The FT - IR measurements showed the materials (PMMA) and (PVA) used in the research with high purity and accordance with the international specifications that are used. Metallic analysis of bentonite by XRD technique showed that the main component of filling material is the Montmorillonite which is 97.54% in addition to Quartz which is 2.45% without any undesirable percentage of Oxides or salts.The maximum absorption of composite films for the two cases (addition ratio 1wt%, 2wt% and particle sizes 25µm &45µm) appears in the Ultra violet region of the electromagnetic spectrum and reached its maximum value at the wavelength of (300nm) for the composite PMMA with treated bentonite of percent 2wt% for the particle size of 45µm. this result is very important for industrial application of PMMA polymer which is considered improvement of Ultra violet absorption in away that can be used for protection purposes such as sun light protection cover, drug sheets, tires painting. It also can be used for medical purposes like sun glasses to protect human eyes from Ultra violet ray which may harm human body tissues because of its poor transmission. The values of allowed and forbidden indirect transition band gap will decrease by increasing the treated bentonite adding ratio to the values (2.4 eV , 1.7 eV) for the percent 2wt% of particle sizes (25µm , 45µm) respectively.So it may be used in manufacturing polymeric sensors and detectors and also in solar cells. Optical constants like (refractive index, extinction coefficient and complex dielectric Constance) when are calculated, we discovered that these constants are influenced by the various of bentonite adding ratio and particle size.

Ablation processes that had been done in various solvents(distilled water and ethanol ,as well as in different concentrations and SDS solution. Structural and optical properties were examined used a scanning electron Microscope (SEM) and transmission electron microscope(TEM) and UV - Vis. Spectrometer. Laser ablation of iron produced multiple nanoparticles spherical nucleus of a grain size less than (10nm) in distilled water, also notes a deviation occurs towards the short wavelengths (blue shift) when using the wavelength (532nm). This shows that the proportion of nucleation is higher than the other wavelengths and that leads to the growth of smaller particles within the plasma. Well happened (blue shift) of nanoparticles with increased energy at wavelength (1064nm) in ethanol solution ,but in the SDS solution showed the best efficiency when the concentration (0.005M) at wavelength (1064nm) .When using a small power lead to production small size and concentration of nanoparticles that reduces collisions with each other and this leads to reduced coalescences. Laser ablation for cadmium showed better efficiency and more stable in ethanol solution, which marked the TEM images of nanoparticles prepared when the wavelength (355nm) more homogeneous than NPs prepared with wavelength (1064nm). Images of SEM and EDX schemes of nanoparticles iron and cadmium colloidal resulting from ablation at the (1064nm) in wavelength ethanol solution show that the purity of the solutions resulting nanoparticleThe nanocolloide solution of Core - Shell system (Cd - Fe) was prepared by using a wavelength (1064) nm in ethanol,where the TEM pictures showed the formation of Core - Shell clearly. As well as the picture showed (TEM) of colloidal nanoparticles with nanoscale particles size less than (10)nm .

The study showed when the input power changed from (126 - 36) mW, then the risetime change from (3750 - 2000) µs respectively, also the spectra response reaching (0.4A/W)at wavelength (450nm).The study shows that spectra properties of panel which doped by dyes have no significant change on dyes properties which dissolved in ethanol, this result confirms that epoxy material is suitable as fluorescent solar concentrators.Spectra properties of panels have been also studied after putting at different weather effect such as heat, rain, wind and dust for three weeks there was negative effect on them ,the absorbance has been decreasing significantly.The study show that panels(LSC) for mixture of dyes have contributed to increase the efficiency of solar cell from 1.775% to 3.534% by using fluorescent panels

تاثير جسيمات (BaTiO3) النانوية على الخصائص الكهرو بصرية للبوليمرات السائلة جانبية السلسلة Effect of )BaTiO3) nanoparticle on Electro - Optical Properties of Side Chain Liquid crystal Polymers

المستخلص: درست في هذا البحث تاثير جسيمات تيتانات الباريوم BaTiO3 النانوية على الخصائص الكهرو - بصرية لمادة بوليميرية بلورية سائلة سايلوكسونية ذات سلسلة جانبية. استخدمت خمسة اوزان جزيئية مختلفة بالوزن الجزيئي تتراوح بين (1.7×〖10〗^6 - 3.1×〖10〗^3) وكانت نسبة المادة النانوية BaTiO3 المضافة (0.07) متساوية لجميع الاوزان الجزيئية ، ولوحظ ان الفولتية تزداد مع زيادة الوزن الجزيئي ، وعند اقل قيمة للشدة نحصل على فولتية التوجيه التام . كما وجد ان اضافة جسيمات BaTiO3 والتي كانت نسبتها متساوية لجميع الاوزان الجزيئية تؤدي الى زيادة كثافة المجموعة الميزوجينية المرتبطة بسلسلة البوليمر وهذا يؤدي الى زيادة اسهام عزم ثنائي القطب الكهربائي في مجموعة (C≡N) الموازية لمحور الجزيئة الطولي للوحدة الميزوجينية ، وكذلك يسهم في زيادة متباينة الخواص العزليةDielectric anisotropy ∆ ε وبالتالي نحصل على ازمان استجابة بصرية (τ_on) ،(τ_off) اقل ، وبذلك تتحسن الخواص الكهرو - بصرية للنظام . وقد قيست ازمان الاستجابة البصرية (τ_on) في حالة الفتح (عند تسليط مجال كهربائي ) وزمن الغلق(τ_0ff) (عند ازالة المجال الكهربائي) وذلك من خلال حساب الفترة الزمنية بين التصفيف الابتدائي والتصفيف الجديد للجزيئات الحاصل بفعل المجال الكهربائي المسلط من ملاحظة التغير في شدة ضوء الليزر اثناء مروره بالخلية الكهروبصرية . ان الفولتية اللازمة لاحداث توجيه تام في جزيئات المادة البلورية السائلة البوليمرية قد حسب لكل البوليمرات المستخدمة ووجد انها تزداد مع زيادة الوزن الجزيئي . وتم قياس التغير في فولتية العتبة عند خطوات ثابتة وتحت درجات الانتقال الطوري TNI لسلسلة من البوليمرات وجد ان الاوزان الجزيئية العالية للبوليمرات تمتلك فولتية عتبة كبيرة وان هذا له علاقة بثابت مرونة النظام . كما وجد ان ازمان الفتح تزداد(τ_on) تزداد عند زيادة الوزن الجزيئي وذلك بسبب زيادة اللزوجة ، وكذلك (τ_on) هو دالة الفرق بين درجة الحرارة المقاسة ودرجة حرارة الانتقال الزجاجي ، وكذلك فان ازمان الغلق (τ_0ff) هي الاخرى تعتمد على درجة الحرارة وهي دالة الى اللزوجة . وقد استخدمت قياسات مطياف الاشعة تحت الحمراء ، وذلك لتحديد معامل الترتيب التوجيهي للبلورات السائلة ذات السلسلة الجانبية وبتحديد اهتزاز حزمة معينة (C≡N) لطيف الامتصاص فقد وجد ان معامل الترتيب التوجيهي يعتمد على درجة الحرارة مع مختلف الاوزان الجزيئية . | In this research study the effect of BaTiO3 nanoparticles on electro - optical properties of liquid crystalline polymers with side chain. Used five different molecular weights of molecular weight ranging from (1.7×〖10〗^6 - 3.1×〖10〗^3)and the percentage of material nanoparticles BaTiO3 added (0.07) equal to all molecular weights, it has been noted that the voltages increase with increasing molecular weight, and when less the value of the intensity we get the operating voltage . . Measured the optic response times (τ_on) when current is switched on (under the electric field) and has also been measured when the electric current is switched off (τ_0ff) (the electrical field is removed), by calculating the time period between the primary layering and new layering molecules which happens under the effect of the electrical field and this period has been measured through calculating the laser light Intensity passing through the cell. The voltages have been needed to bring about a complete guide in the article of liquid crystalline polymer particles may as each polymer used and found to increase with increasing molecular weigh. It has been measured by the change in the threshold voltage when steady steps and under phase transition degree TNI series of polymers found that high molecular weight polymers possess significant threshold voltage, and this has to do flexibility constant of the system . . The response times(τ_on) also found increases with increasing molecular weight due to increased viscosity, meaning that (τ_on) is a function of the degree of difference between the measured temperature and the glass transition temperature. Also, it has been found that switch off times (τ_0ff) the other depends on the temperature which is a function to viscosity . Spectrometer was used infrared measurements to determine the orientational Order Parameters ( )for liquid crystals with a side chain and determining the vibration specific package (C≡N) of the absorption spectrum has been found that the orientational order parameters ( ) depends on the temperature with different molecular weights. It has been found that the addition of BaTiO3 particles lead to increased group density mesogen associated with a series polymer, and this leads to increase the contribution by permanent polar moment in Syano group parallel to the axis of the molecule longitudinal unit mesogen, as well as contributing to the anisotropic increase dielectric anisotropic Δε and thuwe get the responding times ( τ_on), (τ_off) less and thus improve properties electro - optical system.

The equivalent concentration for each of Ra - 226 and Th - 232 and K - 40 has been calculated for all samples and was found to be between (7.60 - 24.04) Bq / kg , (5.39 - 16.98) Bq / kg and (98.78 - 313.10) Bq/Kg respectively.The absorbed dose for these concentrations were calculated using three equations supported by ICRP, UNSCEAR and BECK and we found that the absorbed dose according to ICRP, UNSCEAR and BECK for all samples ranged between (1.378 - 5.675) , (3.85 - 11.00) and (3.881 - 11.496) respectively. The calculated values of the annual effective dose rate and excess lifetime cancer risks (ELCR) were between and (0.591 - 2.436591 ), respectively.The external and internal hazard index also calculated and found ranges between ⁄ and (0.023 - 0.081 ⁄ ), respectively. The results obtained indicate that concentrations of radioactive elements targeted in this study were within safe limits despite the variation in the concentration values between samples. We therefore conclude that the natural radioactivity due to U - 238,Th - 232,Ra - 226,Ra - 228 and K - 40 in crude oil samples collected from al Gharraf oil field in Thi Qar province poses no risk to workers according to standards set by International Commission onRadiological Protection Publication (ICRP60),World Health Organization(WHO)and United Nations Scientific Committee on the Effect of Atomic Radiation (UNSCEAR).

مستويات الاديبونكتين والابلين والهرمونات الاخرى والمعايير الدموية اثناء الحمل وفي مرضى متلازمة المبيض متعدد الاكياس Adiponectin, Apelin and other Hormones Levels and Blood Indices during Pregnancy and in Patients with Polycystic Ovaries Syndrome

المستخلص: The present study aimed to determine the levels of adiponectin and apelin and their relations with all parameters. Investigation in the present study included; hormones, lipid profile, liver enzymes activity and haematological profile in groups of Iraqi Basrah pregnant women during different months of pregnancy and to correlate these levels to maternal age, Body Mass Index, excepted parity and sex of fetuses and correlated with level of adiponectin and apelin hormones only and the results were compared with non - pregnant females as control group. The present study included (180) women ranging from 20 - 40 years old, out of them (70) pregnant and (20) non - pregnant women with polycystic ovary syndrome (PCOs), and (90) females non - pregnant were considered as control group. The pregnant women attended the obsteric units in the general state hospitals in Basra Governorate. They are as follows : Al - Basra General Hospital for Maternity and Childhood, Al - Mawane, Al - Fayha’a and Basra General Hospital which drain most patients from urban and rural areas. None of the selected women suffered from any type of disease. Required data were collected by the researcher depending on direct interview with women before being admitted to the study, using a questionnaire including information on age, parity, month of pregnancy, and geographical area..The Women were divided into two age group (≤ 27 and ≥28 years). Moreover, females were also divided according to BMI into normal (≤ 25), over weight (25 - 30) and Obese (≥30).The month of gestation was determined not only from the date of the women’s last menstruation (LMP) but also according to the ultrasonic reports that pregnant women had. Blood samples (10 ml) were taken from pregnant women at the end of each month of pregnancy and from control group as well as from women with PCOs. Each blood sample was divided into EDTA tube (2 ml) which was used for complete hematological picture study (RBC, Hb, PCV, PLT, WBCs count and WBCs differential count) and the plain tube (8 ml) where the serum was obtained, for biochemical study (Adiponectin, Apelin, testosterone, Progesterone, estradiol, follicular stimulating hormone, luteinizing hormone, insulin, lipid profile and liver enzymes).The results indicated that maternal age had no significant effect on the level of adiponectin, apelin, FSH and LH hormones, while the study showed a significantly effect on level of progesterone, estradiol, testosterone and insulin hormones between pregnant and non - pregnant women. Adiponectin levels decreased in pregnant and non - pregnant females with increased body mass index whereas apelin, estradiol, progesterone and insulin levels increased. When the comparison between pregnant and non - pregnant women was done, a decrease in adiponectin and apelin was noticed. Accompanied by an increase in the level of estradiol, testosterone, progesterone and insulin hormones in pregnant women compared to non - pregnant women.Women with PCOs showed low levels of both Adiponectin and apelin with high levels of Testosterone and Insulin.Results also revealed that age had no effect on total cholesterol, triglycerides, and HDL, in both pregnant and non - pregnant females, but when the BMI was taken in consideration, high levels of these parameters were found in - group of BMI (obese). In addition, the present study showed that age had no effect on liver enzymes (AST and ALT) while ALP showed that the behavior increased up as a different high body mass index in pregnant women, in comparison with the control group. However, ALP activity also increased in high BMI group.Hematological study showed that age had no effect on RBC, Platelets, and hematocrit. Similar results were found when BMI was taken in consideration. Total WBCs showed a non - significant increase in pregnant women as compared with the control group. Adiponectin levels were significantly higher in pregnant females carrying female fetuses compared to those with male fetuses, while the other hormone apelin did not differ between the two groups. The Result of the present study revealed that adiponectin was significantly decreased as apelin was significantly increased with the increased parity.

المستخلص: The present study was conducted in order to evaluate the activity of green alga Enteromorpha intestinalis extracts (methanol and hexane extracts) on growth and development of hydatid cysts of Echinococcus granulosus in vitro and in vivo by using mice type Mus musculus Balb\c that in comparing with albendazole drug. Anti - cancer activity was also evaluated in vitro for both algal extracts by using HeLa cells. Chemical compositions of algal extracts were analyzed by using Gas chromatography - mass spectroscopy (Gc - mass)technique . The hydatid cysts were collected from livers and lungs of infected sheep which slaughtered in Basrah abattoir. While, The algae specimens were collected from Abu Sokhir marshland area /north of Basra. The results revealed that E.intestinalis chemical compounds are carbohydrate , alkaloids, phenols , saponins , triterpenes and sterols compounds. In vitro study showed that the 1 mg / mouse weight of albendazole drug was able to reduce the percentage of protoscolices activity to zero after the third day of treatment. While, the dose 6 98 mg / kg of methanol extract inhibited all protoscolices after five days of treatment, followed by the dose 804 mg / kg of hexan extract that inhibited all protoscolices after six days of treatment.In vivo study revealed that the methanol extract (698 mg / kg) treatment was the best in reducing the weights of organs significantly in comparison with the positive control group it was 2.192 , 0.192 , 0.434 and 0.282 g of liver, spleen, lung and kidney respectively. The methanol extract (698 mg / kg) treatment lowered the average number of hydatid cysts (2.6) more than other extracts treatments , then followed by hexane extract (804 mg / kg) treatment it was 2.8 cyst .This study has identified that the liver enzymes Aspartate transaminase (ALT) and Alanine transaminase (AST) values in the serum of positive control group were higher significantly than negative control group the value of the enzyme ALT was 79 IU / l and the value of the enzyme AST was 118.4 IU / l.All methanolic extracts groups showed a preference in enzyme's values compared with other treatments groups , the value of ALT enzyme of 698 , 688 and 678 mg / kg of methanol extract groups were 46.8 , 45.8 and 44.6 IU / l respectively, while all hexane extracts groups showed a preference in AST enzyme values compared to the other treatments groups, the value of AST enzyme of 804 , 794 and 784 mg / kg of hexane extract groups were 73.6 , 70.2 and 70.4 IU / l respectively. Found a significant increase in the number of white blood cells WBCs in a positive control group ( 4.6 × 013μ), compared with a negative control group and the other groups, While it has been found significant decrease in the Hb (5..8deciliter) and Packed cell volume (PCV) (31..%) values in positive control group as compared with control negative group. The study found that the number of white blood cells WBCs n the methanolic extract group (678 mg / kg) was 4.06 × 103 microliter was as same as in the negative control group, In contrast, hexane extract group (804 mg/ kg) has did not significant difference with negative control group in the Hb and PCV were 11.5 g / dl and 36.8% respectively .Histological study confirmed that there are the histological changes in positive control group included congestion , bleeding , degeneration , infiltration of inflammatory cells and hyperplasia. Whereas the histological changes in group treated with albendazole were bleeding, infiltration of inflammatory cells , atrophy of the glomerulus and fibrosis in some areas . In algal extracts groups the histological changes were infiltration of inflammatory cells, bleeding and congestion.The Gc mass results revealed that the ethanol extract contains loliolide , ethyl stearate , palmitic Acid , ethyl palmitate , phytol , ethyl oleate , ethylhexyladipate and squalene compounds. While, hexane extract has N, Ndimethyltetradecylamine , diisobutyl phthalate , palmitic Acid , ethyl palmitate and ethylhexyladipate compounds.Anti - cancer study showed the algal extracts have an inhibition activity against cancer cells, The half maximal inhibitory concentration (IC50) value of the methanol extract was 79.08 μ/ ml, While, the IC50 for hexane extract was 156.3 μ/ ml.

دراسة تشريحية تصنيفية لبعض من نباتات العائلة السوسبية Euphorbiaceae في العراق Anatomical and Taxomanical study for some plant of Euphorbiaceae family in IRAQ

المستخلص: The study was conducted to investigate several taxonomic aspects which comprised the micro - morphological studies of epidermal layer of leaves, pollen grains, fruits and seeds.In addition to that, the anatomical and molecular studies for 12 species of Euphorbiaceae family which belonged to five genera AndrachneL. , Chrozophora L., Euphorbia L, Mercurialis L. and RicinusL., were performed. One representative species for each genuswas selected; in exception 8 species were chosen for the genus Euphorbia..The current results confirmed that the anatomical characters showed valuable taxonomic traits which can evidently be used to distinguish between species. The most prominent trait was mesophylla tissue in leaves which were observed in three categories;1 - Bifacial leaves : - which found in C.tinctoria, Euphorbia sp ., E. milii, E.annua and R.comminus 2 - Uni - facial (heterogenus) leaves : - this category of the mesophyll was detected in two species only A.telephioides and E.prostrata3 - Uni - facial (homogenus) leaves : - this category were noticed in five species; E.denticulata ,E.helioscopia ,E,macrocarpa , E.microsphaeia and E.peplus The second important comparative anatomical character was the Mid rib, which are in four types with several shapes from which discrimination between the species can be made : - 1. Convex - concave mid rib : - that was showed in E.helioscopia, E.macrocarpa, E.milii and M.annua.2. Convex - convex : - This type was found in three species C.tinctoria , Euphorbia sp.and R. comminus3. Flat - Convex : - This type of mid rib was observed in A.telephioides E.microsphaera, E.peplus and E.prostrata4. Flat - Flat : - This type was observed in only one species E.denticulata In stem, the most prominent parts of taxonomic evidence were pith and vascular bundles.In according to the pith, species can be divided into hollow stem (without pith) and solid stem (containing medulla good configuration). Hollow stem was clear in the stems of A.telephioides , E.microsphaera , E.prostrata and M.annua. While, the solid stem wasseen in the remaining species. Vascular bundles were existed in two types; that's connected vascular bundles that's characterized the hollow stems, and separate vascular bundles. In most of the species with the exception of M. annua, stem with scatteredvascular bundles were in cortex As well as, petiole which have features that a clear taxonomy values .either by outline of petiole or its vascular arc.Micro - morphological studies of epidermal layer of leaves showed very important taxonomical value. This layer of leaves reveals variation in shape of ordinary epidermal cell and nature of anticline cell wall, stomata complexes and Epicuticlular wax crystals.Micro - morphological of pollen was taxonomic evidence as well. It can be considered to divide the species of Euphorbiaceae family into two groups based on the number of germination apertures 1 - Hexocorporate : - this type was confined to C.tinctoria2 - Tricolporate all species studied remainingThe sculpture of pollen wall provided beneficial information invested in the species identification.Both seeds and fruits showed a distinctive role in species identification. Micromorophological study of seeds for species which belong to six genera Andrachne , Chrozophora, Euphorbia, Mercurialis , Phyllanthus and Ricinus were achieved by using Scanning Electron Microscope(SEM). The study concentrated on micro - morphological aspect of Caruncle, seed surface ornamentation and the shape of epidermial cell wall. The result revealed that most studied species were with carunclated seeds ,but some specieswere with ecarunclated seeds as in A.telephioides L. ,C. tinctoria( L) Raf , E.prostrata Atin and P. maderaspatensis L Seed surface ornamentation characteristics showed a significant taxonomical value.Furthermore, current result showed that there are a highly variation in shape, size and color of the seeds walls. With respect to the fruits characteristics, which showed variations in number of mercarpi, shape, size, color and surface ornamentation that can be adopted in the separation of the species studied Molecular study provided significant support for phenotypic and anatomical classification and support genetic convergence between the species in Euphorbiacea family. The genus Euphorbia species showed a significant genetically convergence and participated in predecessors monophyletic. However, the genera in Euphorbiacea family under study probably originated and evolved from different ancestors’ polyphyletic.

دراسة تشخيصية وحياتية لعلقة المياه العذبة Dina punctata Johansson, 1927 (Erpobdellidae : Hirudinea في اهوار السويب من محافظة البصرة جنوب العراق Identification and Biological study of the Freshwater Leech Dina punctata Johansson, 1927 (Erpobdellidae : Hirudinea) in AL - Swaib Marshes From Basrah province south of Iraq

المستخلص: The species Dina punctata is recorded for the first time in Iraq (from Al - Swaib marshes). The identification was conducted morphologicaly and molecularly characteristics. The morphological features summarized as : - - The species D. punctata has vermiform body compressed ventrally, ranging in length from 55 - 60 mm and in diameter from 0.5 - 2 mm. The individuals have a large ability for extening. The pointed anterior end carries small anterior sucker which resembles lips surrounding the mouth opining, while the rounded posterior end carries large rounded posterior sucker. - This species is characterized by heterogeneous features such as the color of the body which changes from blackish gray for Adults to dark brown for Juveniles, as well as the number and arrangement of eyes which is in general four pairs arranged as reverse U shape located on the dorsal anterior edge. The first two pairs of eyes are located on the middle line of the body while the third and the fourth pairs are each located on one side of the body behind the anterior pairs. - The body consists of 34 segments, each of them is divided to five secondary annuli. The fifth annuli of each segment is divided into two subsections, thus the main segment becomes consist of six annuli. - The male and female gonopores are open on the ventral surface of the 12th segment, separated from each other by two annuli, the male gonopore is usually larger and clearer and located forward in the middle of the groove which is separate the annuli b2 and a2 respectively. The female gonopore is smaller and located in the back of the male gonopore in the middle of the groove which is separate the b5 and b6 annuli respectively.Because of the instability in some morphological features, the species D.punctata also identified in the present study according to genetic features.During the genetic study, the region of internal transcription space (ITS2) in DNA was isolated from leech specimens by using special primers for region internal transcription space (ITS2), after isolation, the ITS2 genes are amplified.The results of polymerase chain reaction of DNA were obtained of single bands of 580 base pairs molecular weight for all degrees of hybridization. The sequence of each sample after detecting was entered in the database of National Center Biological Information (NCBI) and the result showed that the sequences of all samples are belonging to the species D. punctata. In the field study, monthly samples of leeches D. punctata was collected from the marshes of Al - Swaib on the eastern side of Shatt Al - Arab river inQurna northern Basrah Province during the period from January 2015 to December 2015. A total of 235 individuals and 623 Cocoon were collected during the study period. The highest number was 58 recorded for individuals during May 2015, while being 335 recorded for cocoons during February 2015. On the other hand there is no occurrence recorded during July - August for individuals, and June - November for cocoons.The study investigates the water temperature, salinity and abundance of individuals and cocoons. The statistical analysis showed negative correlation between temperature and abundance of both individuals and cocoons, while the correlation of salinity was slightly positive with abundance of individuals and cocoons.The study of population sizes structure showed that the size class 40 - 50 mm has the highest frequency during the study period compared with the other size classes. On the other hand, the highest percentage of frequency was 66.7%, which also recorded for the size class 40 - 50 mm.Laboratory experiments showed that the members of a species D.punctata able to tolerate saline concentrations between 2 - 6 psu the survival rate 100%, Also, these worms (D. punctata) feed by different ways, it can be considered Predatory Macrophagous and Scavengers, its food materials consist of invertebrate animals such as Oligochaetes, Lumbriculids, Chironomid larvae; fleshy body of some aquatic snails; and on dead fishes. In the laboratory, the leeches fed well on flesh and livers of chicken, sheeps and caws, The laboratory also studied, Three different types of food effect (chicken liver, zooplankton, and animal feed) on the growth of young leech for a period of six weeks.From the field and laboratory observations, the specie D. punctata reproduces sexually by cross fertilization. The male and female gonopores are easily observed in adults which ranging in length from 45 - 60 mm. as well as the sperm sacs on the mid ventral surface of the body during the reproduction season, which extend in our study during two periods : January - May and December 2015. The sexual reproduction processes were studded in detail and the embryonic development in cocoons was divided into five hypothetical stages according to morphological and anatomical changes and these stages are : - 1 - Depositing Cocoon Stage.2 - Primary Cleavage stage.3 - Development and extension.4 - Differentiation of regions stage.5 - Complement and release stage. The histological structure of the body wall, suckers, reproductive organs and digestive tract of adult leeches were investigated. The body wall consists of thick layers of circular, longitudinal and oblique muscles.The structures of the male reproductive system such as genital atrium, sperm sacs and testis were observed. There are two lateral blood sinuses around the mouth cavity in addition to many nerve cells. The posterior sucker is muscular, and the muscle cells are as a dense net in the peripheral part, while are as a loose cells in the middle what give it a sponge appearance, in addition to primitive glomerular cells, nerve cells and mucus cells

معاملة بذور الذرة الصفراء Zea mays L. بحامض السالسياليك واثرها في تحمل الشد المائي المستحث بمادة الكلايكول متعدد الاثلين The treatment of Corn seeds (Zea mays L.) with salicylic acid and its effects on drought tolerance induced by polyethylene glycol (PEG)

المستخلص: The study was conducted in Plant physiology laboratory, department of biology, college of education for pure sciences, University of Basrah from 1/6/2015 till 10/7/2016 in order to evaluate the effect ofpretreatment (soaking) seeds of corn (Zea mays L.) cv. Baghdad 3with salicylic acid (SA) on germination, early seedlings growth and to minimize the effect of water stress induced with poly ethylene glycol (PEG). The study included the following experiments : 1 - Effect of SA and PEG on germination using a hydroponic culture and Hoagland solution in which corn seeds were soaked in three concentrations (0.1,0.3,0.5) mMof SA in addition to control treatment with distilled water for six hours. Water stress were induced with PEG at concentrations of 0 (distilled water),1%,2%,3%,6%,9% and 12%. This experiment indicated that the optimum soaking concentration with SA was 0.5 mM and that there was no germination at 12% PEG.2 - Effect of interaction between corn seeds pretreatment with DW, 0.5mM of SA for six hoursand PEG at all previous concentrations except 12%, on early corn seedlings growth using hydroponic culture and Hoagland nutrient solution, for three weeks.3 - Effect of interaction betweencorn seeds pretreatment with DW, 0.5 mM of SA for six hoursand water stress induced with PEG at 3% and 6% on vegetative growth using pots filled with a mixture of sand and peat moss for three months.The parameters were evaluated after each of the previous experiments, also , Biochemical test . Plant height, leaves number, root length and number, dry and fresh weight for shoot and roots, while the followingparameters were evaluated in corn leaves after pots experiment : 1 - Biochemical tests included : proline and glycine betain concentrations, total carbohydrates, total chlorophyll, sodium and potassium ions concentrations.2 - Leaves anatomical study to compare the effect of PEG inducedwater stress and the role of its interaction with pretreatment with SA on thegrowth and development of internal structure of corn leaves.The following results were estimated : 1 - Germination percentage : increasing water stress in the nutrient media reduced the % germination significantly when compared with control treatment. Seeds pretreatment with SA enhanced the germination percent and the highest percent was at interaction between PEG at 1%, 2% and SA at 0.5 mM.2 - Growth parameters for seedling at hydroponic culture indicated that plant height, fresh and dry weight for shoot and roots have increased significantly when seeds were pretreated with 0.5 Mm SA All theprevious parameters were reduced significantly under PEG induced waterstress especially at 9%. Interaction between SAand PEG caused apositive significant increases in all studied parameters especially atconcentrations less than 6% and 9% PEG.3 - Growth parameters for corn plants grown at pots have showed a significant increase when pretreated with SA compared with that treated with DW. PEG caused a significant decrease in the growth parameters IIIespecially at 6%. Interaction between DW and 6% PEG recorded the lowest growth in all studied parameters. 4 - Biochemical tests : There was a significant increase in total carbohydrates and total chlorophyll content in leaves of corn plants pretreated with SA in compare with that pretreatdwith DW while the content of proline and glycine betaine were higher significantly in leaves pretreated with DW.In case of PEG induced water stress, the highest total carbohydrates content was at 6%, highest chlorophyll content at 3% while proline and glycine betaine highest content were at 6% PEG. 5 - Sodium and Potassium Concentration : The highest potassium concentration was at plant treated with SA while the highest sodium concentration was at plant treated with DW. Increasing PEG concentrations caused a significant increase in potassium concentration and a significant decrease in sodium concentration. Interaction results revealed that the highest potassium and the lowest sodium concentrations were at interaction between SA and PEG at 6%. 6 - Anatomical study results revealed that increasing water stress effected the leaves tissues structures and this were cleared at vascular bundles tissues (xylem and phloem tissues) and bundle sheath. Upper and lower epidermis, polliform cells were also affected by increasing water stress.The anatomy of leaves also showed that there was a positive enhancement in the structure of leaves tissues in the plants grown from pretreated seeds with SA.

دور مستارجات حشرتي الصرصر الامريكي Periplaneta mericana والبعوض Culex pipiens على فرط التحسس من النوع الاول وعلاقتها مع بعض الائل مستضدات معقد التوافق النسيجي من الصنف الثاني

المستخلص: This study aimed to verify the distribution of Periplaneta americana and Culex pipiens allergy and its association with some HLA class II alleles in asthmatic and allergic patients. 96 healthy (control ) and 96 suspected allergic individuals from the same geographical region ,paired by sex and age were included in this study. Enzyme Linked Immunosorbent Assay test (ELISA) was used to estimate the total and specific IgE antibodies in the sera of studied individuals. The detection of the HLA - DQB1*0602, HLADQB1* 0604 and HLA - DRB1*12 was performed by Polymerase Chain Reaction (PCR).The results of total IgE based ELISA which was conducted on 96 suspected allergic and24 healthy (control ) individuals revealed that there was extremely significant statistical association (P<0.0001) for total IgE concentration with being allergic or non allergic status of individuals. The overall frequency of higher total IgE antibody concentration ( IgE>200IU/ml) was observed in 72.9% of allergic patients and lower serum total IgE levels (IgE<200IU/ml) were associated with 87.5% of healthy individuals. According to the specific IgE based ELISA results the effect of allergic patients age on the IgE seropositivity against cockroach allergens was not considered to be significant(p>0.05),but the effect of sex was statistically significant)P<0.05(.There was no significant effect( p>0.05)for patients age and sex on the distribution of IgE antibodies against mosquito allergens. Out of 96 allergic patients, 59 (61.5%)and 62(64.6%)showed positive IgE antibody response against cockroach and mosquito allergens respectively. Concerning the PCR results the overall frequency of HLA - DQB1*0602 and HLA - DQB1*0604 alleles was %35.6 and %15.3 of cockroach allergic patients respectively and the HLA - DRB1*12 allele was not observed in these patients..Out of 62 mosquito allergic patients, 8(%12.9)showed HLA - DQB1 * 0602 positive results while HLA - DQB1*0604 allele was observed in 4(%6.5)patients and the HLA - DRB1*12 allele was not observed in these patients.The difference in the genotypig results was extremely highly significant(χ2 : 0.030;17.486; degrees of freedom(DF) : 3;p - value=0.00056136) between cockroach and mosquito allergic patients .The association between the presence HLA - DQB1 *0602 , HLA - DQB1 * 0604 and HLA - DRB1*12 and total IgE based ELISA results in allergic patients and healthy individuals revealed that the percentage of HLA - DQB1 * 0602, HLA - DQB1 * 0604 and HLA - DRB1*12 alleles presence in patients having total IgE lower total IgE )IgE<200 IU/ml) was higher than that of high )IgE>200 IU/ml) total IgE patients where HLA - DQB1*0602 appeared in high percentage(69.2%) followed by percentage (15.4 %( of HLA - DQB1* 0604 presence. . The relationship of HLA - DQB1and HLADRB1 alleles with the results of total IgE based ELISA was statistically significant in the least(χ2 : 60.756 and the degree of freedom (DF) : 5;p= P<0.00001) and greatest(χ2 : 11.806 ; the degree of freedom (DF) : 5 ; p = 0.037544) than 200 IU / ml, values .Depending on the association between the presence of HLADQB1* 0602 ,HLA - DQB1*0604 and HLA - DRB1*12 and positive or negative specific results of cockroach or mosquito allergens specific IgE based ELISA results in allergic patients revealed that the percentage of HLA - DQB*0602,HLA - DQB1*0604 and HLA - DRB1*12 alleles presence in cockroach allergic patients having positive results were higher than those ratios that have been observed in patients with negative ELISA results where HLA - DQB1*0602 appeared in high percentage)35.6%( followed by percentage( 15.3% )of HLA - DQB1*0604 . The relationship of HLADQB1and HLA - DRB1 alleles with the results of specific IgE based ELISA was statistically significant (χ2 : 10.412; DF : 3; p - value =0.01536989).Incontrast the percentage of HLA - DQB1*0602,HLADQB1*0604 and HLA - DRB1*12 alleles presence in mosquito allergic patients was found to be higher in negative ELISA results patients also the relationship of these HLA - DQB1 alleles with mosquito allergen specific IgE based ELISA results was not considared statistically significant (χ2 : 3.115 ;DF : 3 and p= 0.37423205).However HLA - DQB1 * 0602 allele was found in the highest percentage (20.6%), followed by allele HLA - DQB1 * 0604 (8.8%).Concerning the presence of HLA - DQB1*0602 ,HLA - DQB1*0604 andHLA - DRB1*12 in cockroach or mosquito allergic patients and healthy individuals,the HLA - DRB1*12 and HLA - DQB1*0602 allels were not found in healthy individuals.The genotyping results difference between cockroach allergic patients and healthy individuals was considered statistically extremely significant (χ2 : 74.485 ;DF : 5 and p =0) as well as the difference in the results of the genotyping of mosquitoes allergic patients and healthy people was statistically with very high significant (χ2 : 23.342 ; DF : 5 and p = 0.00029035).

دراسة تاثيرالتعرض السابق لمادة الايثيلين وايضه في بعض المعاييرالفسيولوجية : دراسة تاثيرالتعرض السابق لمادة الايثيلين وايضه في بعض المعاييرالفسيولوجية والوراثية عند العاملين في معمل البتروكيمياويات في محافظة البصرة والوراثية عند العاملين في معمل البتروكيمي The Study of the effects of previous Ethylene Exposure on Some Physiological and Genetic Parameters in Workers of Petrochemical Plant In Basrah province

المستخلص: The current study was conducted to investigate the genetic and physiological effects of some industrial chemicals on workers of the Petrochemicals Industrial Factory, in Basra Province , as it has been collecting 100 blood samples during the month of January and February of 2011 from each of the exposure in (ethylene section) and the control group of (employees of the University of Basra). and then the samples were divided on the basis of each of the years of occupational exposure to more and less than 15 years , age group to the larger and smaller than 50 years, smoking habits.The results showed that there was a significant decrease in the haemoglobin concentration HB, PCV, RDW and MCV in the more than15 years exposure group in comparison with the control group, while, no significance was detected in the RBC, MCH, MCV ,RDW,MCH and MCHC in less than15 years exposure group . Whereas, a significant decrease in the PCV for the same group was observed.White blood cells parameters’ results showed also variations in their values. In general, WBC did not change significantly in both groups of workers, while, the proportion of the lymphocyte and the of monocyte declined significantly in the more than 15 year of occupational exposure group, in contrast, the proportion of granulated cells increased markedly in the same group. The results of group of less than 15 years exposure revealed that the proportion of monocyte dropped significantly. Conversely, there was a significant increase in the proportion of granulated cells while the proportion of the lymphocyte was not significant . Platelets’ number and average of platelets’ volume decreased significantly in both occupational groupsTurning to the biochemical tests, the results showed significant increase in both liver enzymes ALT ,ASTand bili as well as this increase was found in urea, uric acid and glucose values in both occupational exposure groups. Contrariwise, the ALP creatinine and cholesterol did not reveal significant changes in both groups that in comparison with control group. The total protein decreased significantly in the group of more than 15 year of occupational exposure.Testosterone level revealed a significant decline in both occupational groups, while the Follicle stimulating hormone showed a significant increase in the occupational group of less than 15 year and no difference was observed in another occupational group while LH hormone level was not significant.In case of the genetic effects of the ethylene compounds, DNA was extracted for control and occupational groups and amplification was performed for GSTM1, GSTT1 and Albumin by using PCR technique. The results showed that there was no significant effect of both occupational periods on the GSTM1 gene, while GSTT1 gene was significantly in the workers samples in group more than 15 year of exposure, which was 2.43 times more than the group of less than 15 year of exposure.As regards the impact of exposure to ethylene and loss of genes GSTM1 and GSTT1 showed the results of our study, significant increase in the loss of gene GSTM1 amounted to more than five - fold (5.1) among workers exposed compared to a set of control while the proportion of loss of gene GSTT1 by more than three - fold (3. 1) compared to the group control has been a loss ratio of the two genes together more than eight - fold (8.5) for workers exposed group compared to the control.The light smoke did not reveal a significant effect on the null of GSTM1 and GSTT1 genes that in comparison with the control group, while the study found a significant effect of smoking on gene GSTM1, causing the null of much more than doubled (2.2) times compared with the control group (non - smokers) and the significant effect of smoking on null GSTT1 gene loss as increased visits by the text (1.5) compared with non - smokers also appeared that excessive smoking has an effect on the GSTT1 gene causing loss by seven - fold (7.08) once compared to non - smokers.The effect of the age group (less and more than 50 years old) of the workers on the null of both GSTM1 and GSTT1 was also examined. GSTM1 gene was null six times in both age groups of workers more than the control samples. While the GSTT1 was null in age group less than 50 years old three times more than the control group. As well as this absence was two times in the age group more than 50 years old in comparison with control group.It could be concluded from the present study that the exposure of workers to ethylene and its metabolic impact and clearly on blood standards as well as caused a high level of enzymes AST, ALT and bilirubin and high blood sugar levels and lower total protein and high level of urea and uric acid level as well as the low level of the hormone testosterone as it turns out that occupational exposure to ethylene and metabolic outcomes and length of exposure and smoking for workers exposed role in influencing the genes of detoxification, causing null in each of the gene GSTT1 and GSTM1.

الحساسية الغذائية للروبيان : دراسة وبائية ومناعية وجزيئية في محافظة البصرة جنوب العراق Food allergy of shrimp : Epidemiological,Immunological and Molecular Study inBasra Province, Southern of Iraq

المستخلص: A total of 210 human venous blood samples were collected from Basrah province ( 190 randomly collected from people living in different regions of Basrah province , 10 blood samples from people who did not have a history of shrimp consumption or dealing with it used as negative control group, anther 10 samples of people who are sensitive to shrimp used as a positive control group). The samples were serologically tested by Enzyme Linked Immunosorbent Assay (ELISA) to estimate the distribution of total and specificIgE in the sera of studied individuals . Polymerase Chain Reaction (PCR) was performed to detect the HLA - DQB1*02 , *0302 , *0305 allels. The immunological study included the preparation of two types of Metapenaeus affinis allergens which are the raw allergens and the boiled allergens used in Indirect ELISA test to determin shrimp food allergies by serodiagnosis , while Direct ELISA test was used to estimate the distribution of total IgE by quantitative serological methods in the sera of studied samples. the concentration of protein in antigens extracts was estimated, the protein concentration in the boiled shrimp extract was less than its concentration in the raw extract.The results of direct ELISA test demonstrated a decrease in the level of total IgE antibodies in most of the studied samples , the level of IgE <100 recorded a significant high rate 98.4% which is more than the level of IgE > 100 which recorded apercentage of 1.6% and there was a significant difference between them. The Indirect ELISA test results revealed that the total percentage of IgE distribution of the raw and boiled shrimp antigens were 57.8% and 74.2% respectively and there was a significant difference between males and females .However , the difference was not significant between the age groups P>0.05.The molecular study was conducted to detect the presence of some alleles HLADQB1* 02, *0302, *0305 gene in the blood samples by using PCR . The current study showed that the association of the presence of these alleles and the level of total immunoglobulin is highly significant.Also the current study showed that a high significant difference was found between the positive samples to the studied alleles and the seropositive and seronegative results of raw and boild shrimp allergen specific IgE based on Indirect ELISA (P≤0.01).The results of PCR showed a high frequency ratio of HLADQB1 * 0302 97.2% in allergic patients of shrimp boild allergen and 56.9% in allergic patients of shrimp raw allergen .Also the current study showed a very high frequency ratio of HLADQB1 *0305 98.2% in the individuals who showed positive results for the raw allergen and recorded 65.2%. in the individuals who showed positive results for the boild allergen ,while HLADQB1*02 showed in one sample of studied samples which recorded positive results to raw and boild allergens of shrimp .The current study demonstrated also that the alleles frequency in some of studied samples which are seronegative by Indirect ELISA test , HLADQB1*0302 was 30.9% in raw antigens, while in the negative boild sample was not observed . HLADQB1*0305 was 1.23% in serongative of raw allergen and 16.32% in boild allergen. However, HLADQB1*02 was notobserved in seronagative to raw and boild shrimp allergen.

Three stations were selected to execute the study the former is located in the Euphrates River, while the second is situated about two kilometers apart from the confluence of the Tigris and Euphrates. The third station, however, is located after the confluence of the Shatt al - Arab River with Ghamaj canal. Three replicate samples were collected from each station. some environmental factors were measured ( i.e. water temperature , salinity, pH and dissolved oxygen ) water temperature ranged between 18.4ºC to 32º C during January and May respectively, salinity ranged from (1.9 - 3.8) ppt. during October and May respectively, pH between 6.96 - 8.13 during December, March and April respectively, dissolved oxygen between (7.6 - 16) mg/L during July and September respectively Some other factors concerning the bottom and substrate were also studied namely, bottom texture, pH, salinity, calcium, phosphorus, nitrogen, potassium and organic matter. The study found that the bottom texture was silty clay in station1 while silty in the second and silty mixture in the third station. Other bottom components varied between the three stations. However, pH ranged between 7.24 and 7.55, salinity between (3.2 - 5.3) ppt. Nitrogen from 42 - 150 ppm, PO4 (29.8 - 53.3) ppm, potassium (226 - 346) ppm and Ca+2 from 480 - 986.6 ppm., and organic matter from (10 - 21)%. Three categories of benthic invertebrates were encountered in the studied stations i.e. Gastropoda, Annelida and Insecta, as 25, 16 and 20 taxonomical orders of each respectively. four molluscan species and one order of insects in each of the three stations, while annelida a total of 20 , 11 and 15 species were found in the three stations respectively . the following species were collected during the study Potamothrix hammoniensis (Michaelsen, 1901), Potamothrix bavaricus (Öschmann, 1913) and Psammoryctides moravicus (Hrabe, 1934) of a group of worms Naadd tube and Nais stolci (Hrabe, 1981) and Parainais frici Hrabe, 1941 from Naadd group for the first once in southern Iraq, while generally registers types Nais raviensis Stephenson, 1941 and Homochaeta lactea (Cernosvitov, 1937) of Naadd group for the first time in Iraq. a total of 4497 specimens of benthic invertebrates were collected during the study period (i.e. 1692, 1169 and 1636 from three stations respectively) oligochaetes formed a high proportions in all stations (90.6, 85.2 and 87 %, respectively) and the lowest percentage was for polychaetes amounted to 0.15% and 0.2 % recorded in the first and third stations respectively . out of gastropods Melanoides tuberculata formed the highest proportions ( 55.2 % and 43.7 % and 30.4 % recorded in the three study stations respectively ), but the lowest ratio was 9.7% recorded for the snail Physa acuta in station 2. With respect to tube worm’s group Limnodrilus hoffmeisteri was dominant proportions accounted for 96.9 % in station 1 and 98.6 % in other stations. However, the lowest proportion (0.1 %) was recorded for Tubifex tubifex in station1 and 0.2 % and 0.5% recorded for the species P. moravicus in the stations 2 and 3 respectively. The highest species proportions belong to the group Naididae amounted to 34% and 78.3 % recorded for the species N. stolci in stations 1 and 3 respectively, while in the station2 the worm Pristinella sima was found by 30%. The lowest proportion among all stations was recorded for Pristina aequiseta and Dero nivea amounted to 0.8%. Monthly density of the species recorded during the study was calculated and reached the highest values of 5082, 2058 and 5430 individual / m 2 in the three investigated stations respectively , all recorded for the species L. hoffmeisteri, the lowest value, however, was 11 individual / m 2 were recorded in all the stations for a number of species. Percentage frequency for the species was also studied and found that the species L. hoffmesteria is the only one that occurred during all months in all study stations, as shown by the highest percentage of recurrence (100%) in all months in the stations 2 and 3 , and just eight months in stations1. the lowest frequency (33%) recorded for all stations for a number of species. Stations statistically compared concerning temperature, salinity, pH and dissolved oxygen, as well as densities of molluscs, oligochaetes and the number of species. Significant differences were not found except with dissolved oxygen, which differed significantly between the first and second stations on the one hand and the third on the other hand. Regarding correlation it has been found that mean temperature was positively associated with both pH (r = 0.679) and the mean of salinity (r = 0.350). On the other hand, mean salinity was positively associated with molluscs density (r = 0.331) and temperature was negatively associated(r = - 0.361) with both the number of total species recorded and density of oligochaetes . The total number of species was positively associated with oligochaetes density (r=0.395).

انتاج بروتين cry1I من بكتريا Bacillus thuringiensis بواسطة التنسل الجيني Production of cry1I Protein from Bacillus thuringiensis by Gene Cloning

المستخلص: Bacillus thuringiensis (commonly known Bt) is a ubiquitous, gram - positive and spore - forming bacterium. The organism produces intracellular crystal proteins, which are toxic to insects, during the stationary phase of its growth cycle. Because of its insecticidal activity, B. thuringiensis has been used as a biopesticide. However, it is still necessary to search for more toxins to control insect orders, which have the ability to develop resistance against such pesticides, and also to provide alternatives for chemical insecticides. The purpose of this study is to isolate B. thuringiensis strains that are collected from Basrah, and to identify the cry genes content of these isolations.In this study, 344 Bacillus species were isolated from 22 soil samples collected from different area from Basrah, fifty six of them (16,2%) were identified as B. thuringiensis strains based on colony morphology , microscopic observation of spore position in the cell and genetic analysis . Most isolations were examined by multiplex PCR using for cry 1, cry 2, and cry 9 universal primers in order to identify the type of cry gene content of these isolations. 82% of the isolations amplified cry1 gene, 76% amplified cry9 and 21% amplified cry2 genes.In this study cloned cry1I gene is using specific primer to amplify full length of gene. The cry 1I gene (2169 bp) amplified product was inserted in to the Pst1 and BamH1 sites of pdrive cloning vector joining technique to produce the recombinant vector. The cloning vector then transformed in to E.coli HB101 and the transformant cells colonies were selected by ampicillin sensitive phenotype, the efficiency of transformation was also determined to be 7,8 ×105cfu/μg. After that the cry1I protein is purified from LB broth media supported with ampicillinand used this protein against Tuta absoluta larva within concentrations (100 μg/ml, 150μg/ml, 200μg/ml) .The effectiveness of the toxin is to kill the larvae were in the concentration of (200μg/ml) in the 24 hours after treatment, while least toxicity in the concentration (100μg/ml) need three days to kill all larva.

دراسات تصنيفية وحياتية ووبائية للمثقوبات المتطفلة في الجهاز التنفسي للطيور المائية في اهوار محافظة ذي قار Taxonomic,Biological and Epidemiological Studies of Trematodes Parasitic in the Respiratory System of Some Aquatic Birds in Marshes of Thi - Qar province/Iraq

المستخلص: A total of 420 aquatic birds belonging to four species( Chettusia leucura , Himantopus himantopus, Gallinula chloropus and Fulica atrawere collected in the current study during the period between December 2012 to November 2013 fisolated from Al - Chibayish marshes , eastern of Thi Qar province. Digenetic trematode, Haematotrephus nittanyense was isolated from H. himantopus and C. leucura. Prevalence in those birds were 20.7% , 2.2% respectively. Mean intensity of infection 1.7 , 1.2 respectively. Digenetic trematode , Haematotrephus chengi was found in C.leucura, the Prevalence of infection was 20.7% . These two trematodes were recorded for the first time in Iraqi birds . 2.6% of Ch. leucura were infected with Digenetic trematode , Uvitellina iraquensi , mean intensity of infection was 2.7 . Digenetic trematode , Cyclocoelum mutabile Cyclocoelum mutabile was isolated from F. atra and G. chloropus birds . Prevalence in those birds were 21.2% ,10% respectively. Mean intensity of infection 3 , 3 . Digenetic trematode , Cyclocoelum microstomum was found in 20% of G. chloropus birds and in 15% of F. atra , mean intensity of infection 2.8 , 1.8 respectively.The current study revealed that , most eggs of H. nittanyense , H. chengi and U. iraquensis hatch within the uteri of worms while embryonated eggs of C. mutabile and C. microstomum shed from mature worms hatch within few hours after being placed in water. The mean number of eggs differed between species. Hatching of C. mutabile and C. microstomum eggs did not occur at 12°C . Egg hatching rate of C. mutabile differed from eggs hatching rate of C. microstomum at all temperatures . Temperatures, salinity and acidification of water affectedthe rate of hatching of C. mutabile and C. microstomum eggs , and the results varied between two different species . Storing eggs of C. mutabile and C. microstomum at (0,4)°C for ( 1 - 8) weeks failed to hatch . Storing eggs of C. mutabile and C. microstomum at (7,10,12)°C for (1 - 8) weeks had no effect on hatching success or on eggs hatching rate.A biological study of the miracidia of trematodes which were isolated in the current study showed that , the survivorship and longevity of miracidia were differed among the different species . Temperature, salinity and acidification of water affected the survivorship and longevity of miracidia . Storing eggs of all species at (7,10,12)°C for eight weeks had no effect on survivorship and longevity of their miracidia. The study revealed that , the miracidia of all species were infective to Radix auricularia and Physa acuta snails , but R. auricularia snails more sensitive to infection . The infectivity of the miracidia of all species to R. auricularia and P. acuta snails varied according to the species of these trematodes . Infection rate of R. auricularia snails with the miracidia of all species , mean intensity of infection and the metacercariae output varied according to species of these trematodes, temperature , miracidial density as well as size of snails. Miracidia hatching from eggs stored for 1 - 8 weeks at 7°C not differed in their infectivity to snail. The miracidia of all species hatching from eggs stored for (0 - 8) weeks at 7°C differed in their infectivity to snail according to the species of these trematodes. Age and density of H. chengi miracidia affected the infection rate of R. auricularia snails as well as affected the mean intensity of infection . H. chengi infection had no effect on mortality rate of R. auricularia and P. acuta snails.The results showed that there were differences between the various stages included in the life cycle of the five species of Cyclocoelidae family isolated in the current study . The time required for production and development of these stages varied according to their species, as well as these larval stages were differed among the species in their shapes , sizes and in the product number of them .The current study revealed that , metacercariae of the trematodes which were isolated in the current study fed separately to Gallus domesticus and Anas platyrhynchos failed to produce an infection , although the influence of C. leucura bile on metacercariae of H. nittanyense , H. chengi and U. iraquensis varied according to the species of these trematodes but bile of C. leucura plays a role in increasing excysted juveniles ratios , reduction the time required for excysting and increasing the time of juveniles activity compared with a bile of G. domesticus .In the current study. H. nittanyense showed a clear seasonal cycle of infection in local aquatic birds , H. himantopus ,while the study exposed a clear seasonal cycle of H. chengi infection in local aquatic birds C. leucura . Isolation of U. iraquensis in different periods during the current study from local aquatic birds, C. leucura may refer to its ability to complete its life cycle in a study area. Isolation of C. mutabile from migratory bird at arrival time to the study area may refer to new infections that carried by these migratory birds from their breeding grounds . Abundance of sensitive snails and suitable temperatures in a study area at arrival time of these birds may help this trematode to complete its life cycle in this area thus new infections emerged later and these infections may carry by microstomum isolated from migratory birds only at the arrival time to the study area may refer to new infections that carried by these migratory birds from their breeding grounds as well as this may indicate an inability to complete the life cycle of this trematode in this area.

حياتية القوقع الدخيل Pomacea canaliculata Lamarck, 1822 في شط العرب - محافظة البصرة Biological of the Invasive Snail Pomacea canaliculata (Lamarck, 1822

المستخلص: The present study was concerned with some biological aspects of the invasive snail Pomacea canaliculata (Lamarck, 1822) and for this purpose, monthly samples from Shatt Al - Arab banks in the area of Al - Salhia were collected during the period from October 2014 to September 2015. The study included the monthly variations in the density of snail , its egg masses and the population sizes. In the laboratory, the study included many aspects, these are the relationships between female weight with some measurements of its egg masses, embryonic development duration, hatching percentages under different temperatures, food consumption, salt acclimatization, growth under combined effect of salinity and temperature, effect of food type on growth of newly hatched snails and examine samples of snail to detect the infection with parasites if present. The density of the snail was ranged from four to 13 ind. /m2 recorded during January - February 2015 and October 2014 respectively, while the mean density of egg masses was from two to nine egg mass / m2 recorded during April 2015 and October 2014. The statistical analysis showed that the temperature had positive correlated with density of each of snails and its egg masses. On the otherhand, there are positive correlation between the density of each snail and its egg masses. The snails, which had been collected during the study period, were 19 - 68 mm in length, these measurements were classifying into five size classes. The size class 35 - 45 mm was dominanted for nine months, compared with the size class 55 - 65 mm that had less occurrence.The diameter of eggs varied from 2.5 - 4 mm. The 25°C is the most suitable temperature to get a high percentage of hatching and a short period of embryonic development. There was no significant correlation between the weight of the female and the number of its egg masses.The feeding experiment showed that the amount of food consumed lettuce mild during the study period 30 days by one individual ranged from 3 - 29g. The results of the acclimatization was referred to the ability of all size classes' snails to tolerate the low salinity 2.5 psu with 100% survival percentage, while the snails of size classes at least 10 mm and 10 - 25mm were able to tolerate the salinity of 11psu with 10% and 50% respectivly survival.There are variable effects of the combination of temperature and salinity on growth of newly hatched snails for 9 weeks experiment, these effects were reflected on the weight, length and width, and the highest of these measurements were recorded for snails of 2.5 psu - 27°C combination, while the lowest one was recorded in 7.5 psu - 10°C. The lowest survival percentage was 5% recorded for the individuals of 7.5 psu - 27 and 32°C, compared with 90% of distil water - 17°C. On the other hand, the optimum growth was in 2.5 psu all temperatures, while the optimum growth was in all salinities, and temperature of 27°C.The experimental study of five types of food fresh celery, fresh lettuce, fish food, mixed food and animal protein)on growth of newly hatched snails for 9 weeks. Showed that the mean weight, length and width of snails were depending on the food type. The mixed food gave significant increase in growth 382.1 mg weight, 10.10mm length and7.58mm width compared with the other types of food.The highest survival percentage 95% was recorded for the snails fed on celery, lettuce and fish food. The present study on the snail P. canaliculata does not record any infection by the larvae of parasites

Indian Musa acuminata L. In order to develop a program for micropropagation and were to investigate salt stress tolerance through the effect of NaCl, and water stress through Polyethelen glycol(PEG) and knowledge of the growth retardant of Paclobutrazol (PBZ) in multiplication of the branches vegetative and acclimatization and the effect of Abscisic acid(ABA) on improving salt and water stress tolerance. Halves of shoot tips were used explants which were cultured on MS medium supplied 5 m.l - 1 of Benzyl adenine (BA) to stimulate the multiplication of the branches vegetative and treated with different concentrations of sodium chloride and PEG and salt PBZ and ABA were calculating the number of branches vegetative resulting in diameter and height and number roots and length of follow - up and growth of agriculture and then conduct subculture for several times and then acclimatized and transferred to the plastic house.The results of this study can be summarized as follows : 1 - The addition of 0 or 20 or 50 or 80 or 120 mM of sodium chloride to the MS medium affected the multiplication of the branches vegetative in various percentages. This, in turn, resulted in a signficant increase in the required time to initiate the adventitious buds and lowered their number. There was also a significant difference in the percentage of increasing the numbers of those branches by increasing the salt concentrations. 2 - The addition of the concentrations 0 or 0.5 or 1 or 1.5 and 2 mg.l - 1 of growth retardant PBZ together with 5 mg.l - 1 BA resulted in lowering the required time for initiating the adventitious buds, increasing their number, decreased the number of roots and height of stem by increasing the concentration of PBZ.3 - The initial treatment by 1% PEG significantly increased than the concentration 0.5%. This increase included the number of the adventitious buds, number and length of roots, as well as height and diameter of stem.4 - The addition of 0.1 and 0.3 mg.l - 1 ABA to the nutrient medium led to lower th number and length of roots, stem height and diameter. The leaves became dry and yellow when compared to the control treatment. As far as the interactions between the sodium chloride concentrations in question are concerned, the two concentrations 20 and 50 mM showed a more significant difference than the other concentrations 80 and 120 mM in the number and length of roots, and stem length and height.5 - The addition of the sodium chloride to the nutrient medium resulted in a significat increase in the concentrations of sodium chloride ions and a significant decrease of potassium/ sodium percentage. The addition of PBZ, PEG, and ABA resulted in a significant decrease in chloride ion and a significant increase in potassium/ sodium percentage.6 - The sodium chloride treatment caused a significant increase in the leave content of Proline by incresing the salt. The interaction between sodium chloride salt concentrations and PBZ, PEG, and ABA showed a significant increase in the proline content by increasing salt concentration.7 - The treatment by the two concentrations 20 and 50 mM sodium chloride resulted in increasing the leave content of the total soluble carbohydrates, whereas the treatment by the two concentrations 80 and 120 Mm lowered the leave content. Considering the interaction between sodium chloride and PBZ, PEG and ABA, the interaction showed a significant increase in the leave content of carbohydrates at all concentrations compared to the control treatment.8 - The results showed that the leave content of chlorophyl increased significantly at the two concentrations 20 and 50 mM sodium chloride. Also, the treatment by PBZ, PEG, and ABA showed an increase in the chlorophyl content at all concentrations.9 - The resulted plantlets were acclimatized by sodium chloride salt concentrations and by the interaction of Sodium Chloride and PBZ, PEG, and ABA. The plant height and stem diameter were measured and compared to the control treatment.10 - The treatment by PBZ, PEG, and ABA concentrations that are interacted with Sodium Chloride salt concentrations at 20 and 50 mM led to lower the average percentage of lost moisture and increase the percentage of the success of acclimatization. 11 - Add Sodium chloride to the media has led to changes in the process of gene expression and the emergence of differences in the number and location and intensity of the protein packets.12 - The interaction between the sodium chloride and additives PBZ and PEG and ABA led to the disappearance of some packages and the emergence of other packages in different locations, especially packages 3 and 4.

المستخلص: The purpose of present study was to detection of Rotavirus A and Escherichia Coli from diarrhea cases in children, and characterization of E.coli phag, in addition to study some of factors that influence on Diarrhea.Stool samples were collected between 15/11/2014 and 1/4/2015 from children 0 to 59 months of age who were hospitalized in Basra hospital for women and children, Basra/Iraq. A total of 300 children with acute gastroenteritis were enrolled, including 199 males and 101 females.In this study among children with Diarrhea was 93/300 (31%) Rotavirus positive cases by Immunochromatographic (IC) test as monoinfection (1.66%), coinfection (26.34%), and mixing infections (3%). Out of 50 IC positives fecal samples were tested using electronic microscope, 50(100%) were found positive. A total of 80 stools were examined for Rotavirus using polyacrylamide gel electrophoresis. The overall agreement was 68/80(85%).Furthermore, regardless of the types of infection, monoinfection or coinfection or mixing, Bacteria was isolated, including; 277/300 (92.33%) children had infections with Escherichia coli, 39/300 (13%) cases with Salmonella spp., While, Shigella spp. was reported in 12/300 (4.01%) samples. The identification of bacterial pathogens was later confirmed by Api 20 Enterobacteraceae system. Also parasitic causes were found in 6/300 (2%) samples.Overall, this study recorded 182 /300 (60.66%) of monoinfection cases including; 5 /300 (1.66%) with Rotavirus, 163 /300 (54.33%) with Escherichia coli, 6 /300 (2%) with Salmonella spp., 2 /300 (0.67%) with Shigella spp., 3 /300 (1%) with Entamoeba histolytica, 3 /300 (1%) with Giardia lamblia. Coinfection with another microorganism was observed in 109/300 (36.34%) cases, coinfection with Rotavirus and Escherichia coli were the most common and occurred in 75/300 (25%) cases.Antibiotic susceptibility testing was performed on Muller Hinton agar against five different antibiotics to 30 isolates of E. coli. The antibiotic resistance/susceptibility profile of E. coli isolates revealed that most of the isolates were resistant to three tested antibiotics (Trimethoprim, Ampicillin and Doxycyclin). The phage ɸEC - MH1 was isolation successfully from sewage. The phage titer was determined by serial dilution (10 - 1 to 10 - 9) of the sample by counting the number of plaque forming units (p.f.u.) for each dilution.Results revealed that dilution factor 10 - 2 was the best countable number of plaques. The statistical analysis was significantly decrease P≤ 0.05 in phage titer at the temperature 50C° and 65C° during different times comparing with phage titer at the temperature 37C°. Effects of chloroform on phage titer during different times were completely inactivated comparing with saline environments. Furthermore, regarding some clinical information; the present study showed that 66.33% of the males were more susceptible to the infection with highly significant (P<0.001) than females (33.67%). Mean age (mean ± standard deviation) of all positive cases was 11.02±12.3 months, and the age periods between (0 - 5) and (6 - 11) were significantly prone to the infection.Also, all cases were complained with diarrhea (100%), fever (82.34%), Vomiting (43%) then dehydration (2.67%). In addition, all positive cases become increased in December (32%) and city center (81%). This study showed positive cases increase (69%) of children with artificial feeding

The algal species included Merismopedia glauca, Microcystis flos - aque, Nostoc commune , Oscillatoria pseudogeminata, Four of them were first recorded in Iraq : Lyngbya rubida, Pseudanabaena limnetica, Phormidium laysanense and Stigonema informe. Their ability to produce both anatoxin - a and microcystins was quantified and qualified determined for the first time locally and globally.The growth curve of isolated and purified species was measured after their development in the Chu - 10 liquid medium as measured the growth constant(k) which reached to 0.195, 0.197, 0.246, 0.25, 0.278, 0.29 and 0.528, and the generation time(G) which reach to 1.543, 1.527 and 1.223, 1.204, 1.082, 1.037 and 0.570 hour for the algal species M. glauca, M. flos - aque , P. limnetica, Ph. laysanense, O. pseudogeminata, L. rubida and N. commune , respectively. Neurotoxin (Anatoxin - a) and hepatotoxin (Microcystin) was purified from the blue - green algal species isolated and purified during the current study and quantified and qualitatively by Enzyme Linked Immunosorbent Assay (ELISA). The concentration of purified neurotoxin has been identified as algae M. flos - aque, N. commune , L. rubida, S. informe, L. laysanense, O. pseudogeminata, M. glauca and P.limnetica, which were 0.357, 0.511, 0.598, 0.635, 0.705, 1.119, 1.156 and 1.179 μg/L respectively, While concerning the ability of the species to produce hepatotoxin (Microcystins) it has reached 0.973, 6.128, 1.309, 1.753, 6.209, 3.855, 1.733 and 3.701 µ/L respectively.The Ultraviolet spectrum test showed that the neurotoxin ( Anatoxin - a) had a single absorbance peak at a wavelength of 226 nm , and also the purified hepatotoxin (MCs) showed single absorbance peak at wavelength 240 nm. The infrared spectrum test showed that both types of toxins were present on most of the active constituents or active groups of their standard toxins.The half lethal dose concentration (LD50) of the biomass of the eight species of blue - green algae was determined towards the animal crustacean invertebrates larvae Artemia salina. The results showed that the algal species had high toxicity towards the crustacean animal larvae and that the algae that produce the anatoxin - a at higher concentrations compared to other algae in this study was the most toxic to the larvae as the LD50 reached 29.183, 30.66, 30.716, 33.466, 34.566, 35.866, 36.933 and 37.8 mg / mL for the algae P. limnetica, O. pseudogeminata, M. glauca and S .informe, L. Laysanense, N. commune , L.rubida and M. flos - aque respectively. The half lethal dose concentration (LD50) of neurotoxin(Anatoxin - a) purified from blue - green alga P. malimnica against the larvae of Artemia salina, which reached 0.498 μg/L, while the half - lethal dose concentration reach to 2.59 μg/L for purified hepatotoxin (Microcystin) from the blue - green alga Ph. Laysanense The histopathological effects of neurotoxin anatoxin - a purified from P. limnetica for the first time locally and globally on the brain of white mice type Mus muscules L. were studied under low concentrations of neurotoxin (Anatoxin - a) 0.5 and 1 μg / L for a 15 - day exposure period and increased effects were observed with increased concentration. The results of the microscopic examination at concentration 5µg/L showed begin of occurrence vacuolation ,necrosis in white matter in addition of karyopiknosis of glial cells nuclei, and the beginning of congestion of blood vessel and the decay of the epithelial tissue lining the blood vessel. As demonstrated by the examination the begin of occurrence shrinkage of neuron constituent of the gray matter area as well as less thickness of the gray matter compared with control group . The effects were increased with an increase in concentration to 1 μg/L. In addition to the previous effects, there was a significant deterioration in the thickness of the gray matter and the low percentage of neurons with increasing shrinkage in addition to decay of glial cells in white matter and disappearance or swelling of endothelial cells lining the blood vessel and the expansion dilation , greater congestion , vacuolation and appearance of white matter in spongiform shape, addition to increased necrosis, and hyperpigmentation compared to the control group.Some of the behavioral effects of anatoxin - a were recorded on laboratory mice during periods of injection of neurotoxin represented by weight loss. A significant decrease under probability level p ≤ 0.05 was observed in the weight of mice treated with both concentrations of toxin after 15 days compared with mice in control group , In addition to the loss of sight (blindness) and hair loss thick after 7 - 10 days of injection

عزل وتشخيص مركب ايضي ثانوي جديد لكل من الفطرين Fusarium Trichoderma harzianum وsolani المعزولين من السواحل الرسوبية في محافظة البصرة وتقييم فعاليتهما الحياتية Isolation and Identification of Novel Metabolic Compound From Both Fusarium solani and Trichoderma harzianum Isolated From Sedimentary Coast of Al - Basrah City and Estimate their Activity

المستخلص: with the interest of medical and pharmaceutical uses of the natural products from marine fungi , thirty species of fungi belong to ninteen genus were isolated and identified from sea coast sediment of Al - Faw and Al - Seeba .The fungi Acremonium strictium , Geotricum candidum, Fusarium solani ,F.oxysporum , Penicilium sp. ,Trichoderma harzianum exhibited high inhibition activity toward growth of two reference strains of bacteria Escherichia coli (ATCC25922) and Staphylococcus aureus (NCtC 6571). The six selected fungi were grown in liquid culture media PDB at 25°C for two weeks ethyl acetate was used to extract the active compounds from thefermentation liquid media while ethanol was used to extract the active compounds from fungal mycelia .The crud extracts (fermentation and mycelium ) showed different inhibition activity against the pathogenic bacteria , Proteus mirabilis , S. aureus, isolates E. coli, Pseudomonas aeruginosa Klebsella pneumoniae. and pathoginic yeastes Candida albicans, C.tropicals,Cryptococcus neoformans and dermatophytic fungi Trichophyton verrucosum and Microsporium canis . The results revealed that the fermental fungi extracts has more inhibition activity than mycelial fungal extracts.The minimal inhibitory concentration (MIC) of fungal crude extracts were determined against gram positive and gram negative bacteria and pathogenic yeasts and fungi . antagonisum between studied fungi were evaluated , and the fungus T.harzianum has been the more antagonistic effect against other fungi. The toxicity of the fungal crude extracts were tested by using of human RBC at different concentration the result of this experiment showed that all extracts are non toxic except F.oxysporum extract.From all the above results the both F.solni and T.harzianum extracts showed higher activities ,thus these two extracts chosen for further studies. The anticancer activity of both extracts were studied against Hela cell line and the anticancer activity appeared at 250 Mg/ml and 62.5Mg/ml respectivily. The antioxidant activity of extracts were examined by three different methods ,B - carotene ,hydrogen peroxide scavenger and ferrus ion reduction , the results of three methods showed that both fungal extracts have antioxidant behaviours and the T.harzianum extract had more antioxident activity than F.solani extract and the antioxidant activity of both fungal extracts were increased as the concentration of the extracts increase.An optimization of the fungal growth and bioactivity of both fungi were conducted, by using different Nitrogen sources ( Asparagine , Yeast extract , peptone , Ammonium chloride , Sodium nitrate , Ammonium sulphate ) and carbon sources ( Maltose , Galactose , Glucose , Dextrose , Sucrose ,xylose and Starch ) the results elucidated that yeast extract was the best for growth of both fungi on solid and liquid media and high inhibition activity appear with T.harzianum against bacteria isolates , the carbon source starchenriched the growth of F.solani with more activity in inhibition the bacterial growth while the sucrose give high enrichment to the growth of T.harzianum in solid and liquid media with high activity toward bacterial growth. The study also indicates that the beast temperature and pH which gives the higher activity and growth 25°C and pH6 . The effect of different concentration of salinity were studied as well (1%,2%,3%,4%,5%,6% NaCl)and 2% showed the best concentration .The activity of two studied fungal extracts were superior than commercial antibiotic toward bacterial isolates .Preliminary qualitative chemical tests were carried out on the extracts and their chemical nature were identified .TLC technique were used and the chemical analysis showed that F.solani extract consist of two components with constant Rf values, the components marked as A1 and A2 . A1 shows higher activity against bacterial strains while T.harzianum extract consist of one component.The chemical structures of the isolated compound were

التغيرات الكيميوحيوية المصاحبة للشد الملحي وتقييم دور مستخلص الطحلب الاخضر Cladophora crispata في نبات الرز Oryza sativa L. المستزرع نسيجيا

المستخلص: This study was conducted at the tissue culture laboratory at the Dept. of biology, College of Education pure Sciences from 1/3/2012 - 1/12/2014.With the objective of studing the tolerance of the salt stress of two rice (Oryza sativa L.)cultivars namely Anber and Furat using the technology of tissue culture. . Mature seeds (mature embryo and endosperm) were used as bing parts of explants which were cultivated in a semi - sold( Murashige and Skoog 1962) nutrient medium and some additives such as vitamins and amino acids .The growth regulator Dichlorophenoxy acetic acid (2.4 - D)was used, about 8mg/l , sucrose at 30g.l - 1 . . The study ,also ,tested the effect maltose at 30g.l - 1, and the effect of 0.5g/l of casein hydrolest were tested.the study also included the different of sea water concentrations (0,20,40,60)%on the induction of growth and development of callus ,the effect of green algae extract at Cladophora crispate by adding 1g fresh weight to the nutrient medium with all sea water concentrations.All the features of the callus were tested as well as the effect of the interaction between sea water concentrations and algae extract , as well as interactions among rice cultivar x sea water concentration x algal extract.The study depended on some growth indicators to determine the degree of callus to tolerance towards salt stress .the resistance of callus to salt depended on regeneration through the required of time for the formation of embryos ,number of germinated embryos ,and number of plantlets .The concentration of the major metal ion : sodium, potassium, phosphorus, calcium ,magnesium, potassium/sodium percentage , and the minor metal ions : iron ,copper, manganese were also some chemical components such as protines and amino acid proline measured, were also measured .The randomized block design (C.R.D)and factorial experiments were used depending ten replicates per treatment .The results can be summarized as follows : 1 - The results showed that the addition of sugar di maltose as an energy source and Casein hydrolyses to the nutrient medium had appositive effect on significant decrease in the required time to mitiate the callus ,in the increase of callus induction percentage and in the increase of freshweight of initial callus. .2 - The effect of sea water and algae extract : . A - The current study shaued that the addidtion of 20 and 40 % sea water to the nutrient medium resulted in a significant increase in the required time to induce the callus ,and a significant decrease in the percentage of callus induction and weight of the mitial callus as compared with the control treatment .The concentration 60%0f sea water caused the mature seeds to lose their ability to germinate and induce the callus if no induction occurs at all . The effect of algae extract resulted in a significant decrease in the required time for callus induction ,and a significant increase in the percentage of callus induction ,the weight of the mitial callus and 0,20,40% of sea water as compared with free algae extract medium.B - The results showed that the addition of 20% of sea water to the nutrient medium that is prepared for the growth of the embryo callus led to a significant increase in the fresh weight as compared with the control treatment , whereas the two concentrations 40 and 60%sea water led to a significant decrease in the embryo callus weight .The effect of the algae extracted to a significant increase in the fresh weight of the embryo callus with sea water concentrations as compared with the free algae extract medium.C - The addition of 20,40 and 60%sea water cause a significant decrease in the number of the somatic embryos ,thir germination auerage ,number and germination of the formed plantlets . This addition also caused a significant increase in the required time to stare the germination of the somatic embryos as compared with the control treatment .The addition of the algae extract led to increase the number of formed embryos ,germination percentage ,and number and percentage of plantlets ,wher was the addition led to lower the required time to germination the embryos compared with the free algae extract medium.D - The addition of 20 ,40 and 60% sea water to the nutrient medium resulted in a significant increase in the concentration of sodium ,calcium ,and magnesium ion in the embryo callus ,while a significant decrease occurred in the concentration of potassium and phosphorus ion and thedpotassium/sodium percentage as compared with the control treatment .The abone mentioned concentrations 0f sea water led to significant increase in concentration of ion ,copper, and zinc ions ,and significant decrease in manganese ion ,The addition of the algae extract caused in lowering the concentration of sodium ion .This decrease was significant in the 60 % sea water medium. The ingrease of potassium ,calcium ,phosphorus, and magnesium ion in embryo callus tissue when compared with free algae extract medium and was significant with some sea water concentration.E - The results ,also ,showed that the addition on 20, 40 and 60% concentrations0f sea water resoled in a significant decrease in concentration of some chemical ingredients such as protein and amino acid proline of the embryo callus in comparison with the control treatment . as far as the effect of the algae extract is concerned ,the addition of this extract to the nutrient medium led to a significant increase in the concentration of the proteins and amino acid prolne as well as with all sea water concentrations.F - The results of study showed that the addition of 20,40,60% sea water led to a significant increase in the rate 0f effectiveness 0f the enzyme Super oxide dismutase (S.O.D) and enzyme Ascorbate peroxides (APX),reaching the highest rate of effectiveness of the enzyme at the concentration 0f 60% compared with the comparative treatment , whil the highest average of the effectiveness of enzyme Catalase (CAT)and glutathione piroxidase (GP)and polyphenoloxidase (ppo)was at the concentration 20%sea water then it started to decline when increasing the concentration of sea water from 40 to 60% As for the algae extract it has been shown from the results of the current study that the addition of algae extract to nutrient medium to a high effectiveness of enzyme SOD,CAT ,APX and GP and more significant with all concentration of sea water The impact of algae extract on the effectiveness of the enzyme PPO has led to increasing the effectiveness of this enzyme but did not amount to a significant level except with sea water nutrient medium .G - The results of the current study showed a significant increase of the Amber cutivar in the percentage of the callus induction and the required time of this induction as well as the Wight of the initial and embryo callus ,number and germination percentage of thesomatic embryo , number of plantlets ,as wall as the percentage of the accumulation of potassium ,phosphorus ,calcium, and manganese ions ,as will as in the potassium/sodim ratio focus histidine proline and the effectiveness of the enzyme SOD and CAT enzyme and enzyme GP. While the product was higher than in the accumulation of Firat magnesium ion ,zinc copper and in the effectiveness of the enzyme in APX & PPO . .

تقدير الهستامين في بعض الاغذية المحلية وتحديد جينات الهستدين (hdc) في البكتريا المعزولة منها ودورها في تراكم الهستامين Estimation of histamine in some local food and detection of histidine genes (hdc) from their isolated bacteria and it’s role in accumulation of histamine

المستخلص: ELISA technique was used to estimate of histamine in muscles of several types of local fresh fish, including : Tenualosa ilisha, Megalaspis cordyla , Chirocentrus dorab and Scomberoides commersonianus in addition of the shrimp Metapenaeus affinis , all samples of fish and shrimp were collects from Fao markets in Basarah city .Results showed the percentages of histamine in all types of fish, as well as shrimp were : 4.483 and 3.953 and 3.353 and 3.16 and 2.03 mg/kg respectively.Accumulation of histamine in fish after refrigerating for three days was also determinated. Results showed that the values of histamine accumulate were increased within preservation period .On the third day of histamine accumulate of C. dorab , T. ilisha , M. cordyla , S. commersonianus and shrimp were 4.56 , 3.99 , 3.43 , 3.19 and 2.01 mg / kg, respectively. While , on the first day were 4.01 , 3.65 , 3.03 , 2.98 and 1.89 mg/kg respectively .ELISA technique was also used to estimate histamine in Ripening cheese such as cheddar , Alkuda , Almoszerla and Oloadam cheese and smoked Hajdu . They were 4.267 , 2.433, 1.167 , 3.667 and 1.833 mg / 100 g , respectively.Many bacteria were isolated isolated from fishes and shrimp, they identified according to : growth characteristics on selective media, morphological, and microscopic examinations in addition to biochemical tests.Fifty three isolates of bacteria were found, they were : Klebsiella pneumonia sub. pneumonia , Klebsiella oxytoca , Morganella morganii sub. Morganii, Enterobacter aerogenes, Enterobacter cloacae , Cronobacter sakazakii ,AEnterobacter taylorae, Citrobacter freundii , Citrobacter amalonaticus , Proteus marina, Proteus vulgaris , Proteus mirabilis, Hafnia alvei , Escherichia coli, Serratia marcescens, Serratia fonticola , Vibrio vulnificus, Vibrio diazotrophicus , Vibrio hollisae , Vibrio alginolyticus, ,Vibrio cholera, Vibrio parahaernolyticus, Vibrio fluvialis, Lactobacillus helveticus, Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus reuteri, Lactobacillus rhamnosus, Lactobacillus johnsonii, Lactobacillus salivarius, Pseudomonas aeruginosa, Pseudomonas fluorescens, Staphylococcus saprophyticus, Staphylococcus aureus , Staphylococcus intermedius , Staphylococcus epidermidis, Bacillus pumilus , Bacillus licheniformis , Bacillus firmus , Bacillus subtilis, Bacillus alvei , Aeromonas. caviae , Aeromonas veronii bv.veronii , Aeromonas eucrenophila, A. sobria , Aeromonas veronii and Aeromonas encheleia .Isolation and identification of Lactobacillus from all samples of ripening cheese were done. Six species of Lactobacillus were found and as a follow : Lactobacillus plantarum , Lactobacillus delbrueckii, Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus fermentum and Lactobacillus paracasei .DNA was extracted from all types of G+ and G - bacteria which isolated from fish and shrimp in addition to Lactobacillus bacteria that isolated from ripening cheeses . the DNA of all bacteria was good and pure .Polymerase chain reaction (PCR) technique was used for identification all isolates of Lactobacillus which were isolated from fish and shrimp, as well as ripening cheese depending on the bacterial 16S rRNA gene sequences of bacteria with using different types of diagnosed primers, genes had been identified for : Lactobacillus acidophillus , Lactobacillus plantarum , Lactobacillus delbrueckii , Lactobacillus fermentium , Lactobcillus helveticus , Lactobcillus crispatus ,BLactobcillus gasseri, Lactobcillus reuteri , Lactobcillus rhamnosus, Lactobcillus paracasei, Lactobacillus johnsonii , Lactobacillus salivarius and Lactobacillus casei .Nine primers were in RAPD technique to find out the genetic link between different strains of Lactobacillus bacteria, the results showed that the number and location of randomized bands were differed in some bacterial species but others was fitted and produced a variety genetic of bacterial strains, in particular a number of bands as possible to get a variety of different genetic profiles among Lactobacillus isolates .The results appeared different styles of bands and presence of specific bands in Lactobacillus bacteria in all primers . The results obtained from RAPD technique showed that the total number of bands were 630 bands, the total number of bands which formed genetically was 127 and the percentage of total proportion of genetic variation among the isolates was 20.15% .The results found of genetic primers scheme that the genetic distance was as close as possible between bacteria L.fermentum and L.rhamnosus and was a part of the one genetic group, but L.helveticus was close as possible genetically to this group , and then the L.johnsonii and L.acidophilus was more genetically distant to this group. Also it found that the genetic distance was very near between L.plantarum and L.paracasei and were a part of a one hereditary group and found also that L.reuteri closest genetically to this group, then followed by more genetically L.delbrueckii . However, L.acidophilus was also more genetically distant to this group .CThe results revealed that L.salivarius and L.crispatus were a one hereditary group and the genetic distance for this group was very close to the L.gasseri and it was farther genetically for genetic group, which includes L.fermentum and L.rhamnosus , also found that the bacteria L.casei showed far genetic distance between them and the groups of Lactobacillus .All fifty three isolates of bacteria which isolated from fish , shrimp and ripening cheeses that producing and did not producing histamine subjected to amplified genes which responsible of the histamine production by using the primers HIS1 - F/HIS1 - R ; JV16HC/ JV17HC ; Hdc - f/ Hdc - r ; 106/107 and UNI - L/ UNI - R . Amplification results showed that all primers used to amplified genes of histamine gene different genes sizes depending on the types of bacteria when were positive or negative to Gram stain and their OrigenIt was found the size of the gene was 350 base pairs , was found in G+ bacteria which isolated from fish , shrimp and cheese ripening . These bacteria included : L.acidophilus ,L.helveticus ,L.crispatus, L.gasseri ,L.casei , L.reuteri , L.fermentum,L.rhamnosus, L.paracasei, L.johnsonii, L.salivarius L.plantarum , L.delbrueckii , S.aureus , S. saprophyticus , S.epidermidis , S. intermedius , Bacillus pumilus, B.subtilis, B.licheniformis, B.firmus and B. alvei .May same results were found when amplified HISI - R/HISI - F primer , the size of histamine gene most positive Gram bacteria stain .High size of histamine gene 709 base pair appeared when amplified Hdc - r/ Hdc - f primer .This gene was found in G - bacteria which isolated from fish and shrimp . These bacteria included : Pseudomonas aeruginosa , Pseudomonas fluorescens, Klebsiella pneumonia , Morganella morganii , Enterobacter aerogenes, KlebsiellaDoxytoca, Hafnia alvei, Enterobacter cloacae, Vibrio alginolyticus, Cronobacter sakazakii, Escherichia coli , Enterobacter taylorae, Proteus vulgaris, Proteus mirabilis, Vibrio vulnificus , Vibrio diazotrophicus, Vibrio hollisae , Vibrio fluvialis , Serratia marcescens and Serratia fonticola .However , the size of histamine gene was 530 base pairs , when amplified 106 / 107 primer , the gene was found in most G - bacteria .On the other hand , the UNI - L/UNI - R primer did not amplify in all isolates of bacteria which isolated from fish , shrimp and ripening cheeses .Extraction of plasmids from all isolated bacteria was done . Results showed that isolates have different types of plasmids bands (small and large size) and when the electric deportation of the genetic material of plasmids on gel agarose while some other isolates appeared possess one plasmid.In this study , PCR technique was not detected the presence of histamine genes in plasmid of bacteria , because not occurred any amplify for any type of primers used . This indicates the presence of histamine genes on the genome of the bacteria and not on plasmids of bacteria .
