Abstract: This study entails some of the theoretical characteristics of Bose - Einstein intensification of the ideal gas properties, since the wave function behavior has been studied and analysed according to the effect three types of external potentials trapping that are used in the production Bose - Einstein condensation which are (harmonic potential, optical lattice potential , and double well potential) that have been used as individual or overlapping potentials, and the value of the non - linear has been confirmed according to fixed values in the whole study in order to the study the effect of the other elements. The effect anisotropy AL has been studied according to the behavior of the wave function and the distribution potential where the harmonic potential has individually at first, than it has been overlapped with the optical lattice potential in order to study this factor. Furthermore,the effect of this factor has been explained due to the distribution potential, function wave and relation type between the factor itself, chemical potential and energy. Additionally, we have used the intertwined harmonic potential with the optical lattice to study the effect of optical lattice potential factor q after confirming the harmonic potential AL at certain values, with exposition of it's effect the wave function behavior and distribution of potential with explanation to the nature of the relation between the chemical potential and energy with this factor. In addition to that, we have studied the influence of the center of double well potential coefficient A on the nature and behavior of the wave function and potential, and the nature of the relationship between this factor and chemical potential and energy. Noting the effect of these factors on the behavior of the wave function and the distribution of potential, therefore it has effect in Bose - Einstein condensation production.

Abstract: In this work, the dynamics of electron transport through a system consists of qubit (two coupled quantum dots) electrostatically coupled with single - electron transistor (quantum dot coupled to leads). The time - dependent Hamiltonian, that is used to describe the system energy, includes the electrostatic coupling between the qubit and the single - electron transistor. The time - dependent equations of motion for all the creation and annihilation operators are expressed in Heisenberg representation to derive the differential equations of motion for the quantum dots occupation numbers of the qubit and the single electron transistor, the related equations of motion for the correlation functions and also the formula that calculates the current which tunnels from the left lead to the single - electron transistor quantum dot. The system of equations of motion are treated by using the wide band approximation, and are solved numerically by using six order Runge - Kutta method, where the error is calculated at each step of time. By getting use of the system of differential equations solutions, the qubit and the single - electron transistor quantum dots occupation numbers are calculated as a function of time, in addition to the current that tunnels from the left lead to the single electron transistor quantum dot as a function of time.The main goal of this study in to investigate the effect of the parameters that related to the qubit and the single - electron transistor and their role in determing the electron transport process features through the whole system. These parameters, that are related to the initialization, manipulation and measurement processes, are the qubit and the single electron transistor quantum dots energy levels, the coupling strength between the qubit quantum dots, the electrostatic coupling between thequbit and the single electron transistor in addition to the coupling strength between the single - electron transistor quantum dot and the leads as well as the leads properties such as tempreture and band width. The effects of quantum dots energy levels tuning and the symmetry of the coupling with leads on the electron transport through the system are also investigated.Our study highlights four important physical features that related to the initialization, manipulation and measurement processes, these are : 1. The occupation numbers of the quantum dots of the qubit and the single electron transistor and the current of SET at the final time of measurement.2. The charge accumulation on the qubit quantum dots, at the final time of measurement, on the far - removed quantum dot and the nearest one to the single - electron transistor, that can be controlled by appling bias voltage and gate voltage.3. The determination of the time - current dependence if it follows the dependence of the far - removed or the nearest qubit quantum dot occupation number on time.4. The role of qubit energy levels tunning and the asymmetric coupling with the leads in determining the suitable initialization and manipulation processes get the quantum measurement with high quantum efficiency.

Abstract: 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.

Abstract: 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.

Abstract: 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.

The H. himantopus was infected with the nematode T.nouveli and the prevalence of infection was 25.8% , bird.Furthermore, the Chettusia leucura was infected, the mean intensity was 3.3 worm in each infected birds. The nematode T.dubia was isolated from H. himantopus with the isolated from the Ch. Leucura mean intensity was 1.7.The nematode T.spinosa was isolated from H. himantopus the the mean intensity of infection was 2.3 and it was isolated from the Ch. leucura , the prevalence of infection 4.3% and the mean intensity was 1.8 worm in each infected worm.The record of these three nematode is considering the first record in Iraq.Microtetrameres inermis was isolated from the Sturnus vulgaris, the each infected birds.Himantopus himantopus from April 2014 to March of 2015.This bird was infected with three species from family Tetrameridae, The seasonal variation study of infection prevalence of Tetrameres spp.in, H. himantopus that there was II Summarycomplete seasonal cycle for nematodes T.nouveli, T.dubia , and T.spinosa .The nematode T.nouveli had hightest infection prevalence in summer the decrease in autumn, winter and spring while the infection prevalence of nematode T.dubia was hight in summer and autumn then decrease in winter and spring. The infection prevalence of nematode T.spinosa was generally low with little increase in autumn .The results of the current of the Ch. leucura indicated that this bird was infected with three species which nematodes T.nouveli, T.dubia and T.spinosa and they had seasonal appearance . There was not any significant effect of host sex on prevalence of infection, and it showed decreased in prevalence of infection when the bird's weight was increased.The study of lifecycle of nematodes : T.nouveli ,T.dubia and M. inermis revealed obtainment the larval stages after success the infection experimental of the grasshopper Schistocerca gregaria for the first time the three isolated nematodes from family Tetrameridae in this study which it was T.nouveli , T. dubia and M.inermis and was included the lifecycle of the three species . The differences were including the period of time to produce and developing the larval stages in addition to the differences in their shapes, it was revealed that were clear differences in the structure and their shape of the tip the posterior end of the third larval stage. The end of the third larval stage of the nematode T. nouveli had three caudal papilla and the posterior end of nematode T.dubia had five caudal papilla while the end of the third larval stage of M.inermis did not have any caudal papilla , so we can distinguish these nematode larval stage depended on the prevalence this character in their third larval stage.The experimental infection of the Columba livia domestica with nematode M.inermis was successful.While the experimental infection to the Columba livia domestica with nematode T.nouveli ,T.dubia .was failed The experimental infection of the Gallus domestica with nematodes of Tetrameridae T.nouveli, T.dubia and M.inermis was failed too.

Abstract: 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

Abstract: 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.

Abstract: 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).

Abstract: 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.

Abstract: 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).

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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
