المستخلص: تضمنت هذه الدراسة اختيار خمس محطات اربعة منها على نهر دجلة المار بمدينة سامراء بعد جسر سامراء والمحطة الخامسة والتي تمثل رقم 2 على مياه مجاري سامراء قبل ان تصب في مياه نهر دجلة.وقد تم اخذ العينات للمدة من شهر تشرين الاول 2010 حتى نهاية شهر ايلول 2011 وقد | The study included chosen five stations for water sampleing, four of them at Tigris river while the fifth station was chosen at samara sewage before meeting with Tigris river.Samples were collected monthly started from October 2010 until the end of September 2011. The study included the study of some physical, chemical and biological characteristics for river water and sewage and noticed the effects of sewage water on quality of these water in Tigris River, these characteristics clued in air , water temperature, electrical conductivity, pH, total dissolved solid, Total Suspseneded solid, dissolved oxygen(Do), biological oxygen demand (BOD), total hardness, calcium and magnesium hardness, chloride, alkalinity, nutrients concerteration, ( phosphate, nitrate) in addition the total number of bacteria and coliform bacteria.Water Temperature ranged through out the study ranged between (5° - 35°), while air temperature ranged between(5° - 38°) , Electrical Conductivity in the river ranged between (280 - 1480) mc/cm, where in sewage the electrical conductivity ranged between(1200 - 2180) mc/cm, while pH value tened to be slightly alkaline, it show very close value where ranged between(5.3 - 8.8). It was noticed that the pH value tened to be slightly acidic from January to August 2011. The results also show that the water were in good airation where the value of dissolved oxygen ranged between (3 - 10) mg/L in station one and stations five while the value of dissolved oxygen in stations two and three range between (2 - 6.5) mg/L.The result also showed that the concentration of total suspended solids ranged between(20 - 798) mg/L. where it has high value in April in all stations, this propably due to increase of discharge of the river which accompanied by suspended solid, while the dissolved solids in all station range between (250 - 1470) mg/L.The highest value recorded were, 1470 mg/ L on May 2011in station two.The value of total hardness for Tigris river ranged between hard to very hard(125 - 360) mgCaCO3/L in station one, four and five, whereas its value in stations two and three ranged between (200 - 925) mg/L. Calcium ion which is the cause of calcium hardness was higher than magnesium cencenrteration which is responsible of magnesium hardness, where calcium hardness ranged between (75 - 587.5) mg/ l and magnesium hardness ranged between (5 - 500) mg/l. chloride concentration ranged between (8 - 127.5) mg/l in all station, chloride cencetration in stations one, two, and five were in the allowable wnorld limit(8.5 - 68) mg/l. Alkalinity results showed that it related to carbonate and bicarbonate, and its ranged between (110 - 900) mg/l.While phosphate value ranged between(0.0106 - 1.999) µg atom - PO4/L, the lowest values were recorded in Tigris river, While the high value recorded in sewage station two, while nitrate value were fluctuated in all stations but the high value recorded in the second station is ranged between (0.0103 - 1.140) µg atom NO3/l. Result of microbiological study shown that there is high number of bacteria the average of total count of bacteria were(39.7×105، 17.31×105، 267× 105، 3.17 ×105، 0.0531×105) cell/ ml for all stations respectively, so it has been suggested that the water in Tigris river considered as polluted to very polluted while the resulty of Coliform bacteria were very high and the average number for all stations respectively as follows (209 × 105, 9809×105 , 25× 105, 1×105, 0.004×105 ( cell /ml According to these result the water is not suitable for direct drinking.Statistical analysis for most factors studied show significant differences between station one and station two and between station one and station three as well in stations four and five and there is no significant differences between station two and station three.

عوامل الخطورة لطفرات الجينين CBS وMTHFR لقبل الارتعاج لدى النساء الحوامل في النجف Risk Factors of CBS And MTHFR Gene Mutation For Preeclampsia In Pregnant Women In Al - Najaf

المستخلص: تعد الاصابة بقبل الارتعاجPre - eclampsia من الاعتلالات الخطيرة التي قد تظهر في الثلث الثالث من مدة الحمل اذ تتصف هذه الاصابة بارتفاع ضغط الدم وظهور بروتين الالبومين في الادرار. وقد ظلت اسباب نشوء هذه الحالة غير واضحة المعالم, اذ اعزيت بعض من اسبابها الى ا | Preeclampsia is considered as one of the serious complication in the third trimester of pregnancy. It is associated with hypertension and proteinuria. The causes of preeclamptic are still not well understood. Evidences suggested the involvement of metabolic related mutations in the disease. In the current study, the genetic mutations of CBS and MTHFR genes are studied as markers for the diagnosis of preeclampsia. Sixty preeclamptic pregnant women and forty healthy pregnant women as control group diagnosed by the physicians at Azzahra Teaching hospital for obstetrics &pediatrics in Najaf province from December 2012 to August 2013 The poly merase chain reactions technique was used to evaluate the incidence and frequency of C?S &MTHFR mutations. A questionnaire was conducted to obtain the information of the patients and the control group. Genetic mutation were detected by polymerase chain reaction (PCR)and agaros gel electrophoresis. The information indicated that the age of pregnant women, gestation age, previous history of the patients, family history and parity are involved in the pathogenesis of preeclampsia. The results of the present study of preeclampsia showed a significant increase (P ? 0.01) in patients (25 - 34) years old when compared with the other group. where the results found a significant increase (P <0.01) of Preeclampsia occurred during (33 - 39) weeks of pregnancy. And in the patients with previous history for preeclampsia there was significant increase (P<0.001) compared with healthy pregnants. Pregnants with preeclampsia in the family history showed significant increase (P< 0.01) as for women pregnant for the first time showed and significant (P<0.01) and constituted 8% pregnanst with preeclampsia who had diabetes mellitus. The extraction and quantification of cell free fetal DNA (cff DNA) revealed a significant (P<0.0001)increase in preeclamptic patients when compared with those of healthy pregnant women. It is confirmed by the use of an internal negative control through the monitoring of SRY gene (Y chromosome gene) amplification that the gene belong to the infant and 40 pregnant woman were followed up till the labor. Thus, 9 of them had delivered males, while 30 had delivered females. The wild type SRY gene band was obtained clearly from those of male delivery, but not from those of female delivery. Mutations of C?S gene were analyzed by theuse a primer intended to amplify a fragment of171 bp.The rate of mutation was found to be 51.7% and 5% in preeclamptic patients and healthy pregnant women respectively and Odd Ratio=20.31, P value=10 - 7. The C677T mutation of MTHFR gene was verified by the use of a primer designed to amplify a fragment of 198bp. The prevalence of mutation was indicated to be 68.3% and 17.5% in the preeclamptic patients and healthy pregnant women respectively and Odd Ratio =10.17, Pvalue =6.2*10 - 7. Results demonstrated the wide involvement of C?S and MTHFR gene mutation in the pathogenesis of preeclampsia, but they are no crucial for the development of the disease. In addition there are so many factors thatmay be involved in such development.

دراسة بعض الجوانب المناعية لاصابات اللشمانيا في عينة المرضى العراقيين Study of Some Immunological Aspects of Leishmaniasis In Sample of Iraqi Patient

المستخلص: This study was carried on 145 patients infected with leishmaniasis including; 75 with CL, 70 with VL, attending Al - Karama Teaching Hospital, Central Public Health Laboratory and Central Pediatric Teaching Hospital, during the period October 2013 to February 2014 were enrolled in this study, in addition to 30 healthy control collected from the National Center for blood donation for the same age groups for a group of patients. No clinical autoimmune manifestations such as arthralgia or cutaneous vasculitis were reported in any patients. Based on direct skin smear examination and serum samples analysis, the patients were distributed into two clinical groups : 30 patients suffering from cutaneous leishmaniasis and 30 patients suffering from visceral leishmaniasis patients.The presented study aimed to confirmation of diagnosis cutaneous leishmaniasis depending on direct skin smear and visceral leishmaniasis based on indirect immunofluorescent assay test IFAT, then investigate the association of IgG autoantibodies against some antigens, especially : nuclear antigens, like : ds - DNA, nucleosome, histones, SmD1, PCNA, ribosomal P0, SS - A/Ro60kD, SS - A/Ro52kD, SS - B/La, CENP - B, Scl70, U1 - snRNP, AMA M2, Jo1, PM - Scl, Mi - 2, Ku and against cardiolipin, in order to correlate the types of diseases presentation (cutaneous or visceral) with the presence of these autoantibodies in a sample of Iraqi patients.The study was reached to the following results : 1. The direct microscopically examination of skin smear in CL patients, showed positive results in 30 cases (40.0%) compared to 45 cases (60.0%) negative results, and was a significant difference at the level of (P?0.05).2. The anti - leishmanial antibodies by Indirect immunofluorescent assay test in VL patients, showed positive results in 30 cases (42.9%) compared to 45 cases (57.1%) negative results, and was a highly significant difference at the level of (P? 0.01).3. The age groups most affected in CL were 16 to 40 years, with high significant differences at the level of (P? 0.01) were observed when compared with the other age groups. As for patients with VL, who aged between 3 months to 9 years, they showed variable significant differences between age groups in female while there were no significant differences in male at the level of (P?0.01). The majority of patients were aged 3 to 4 years and they represent 9 (30.0%). The study result showed 16 CL patients (53.3%) have only one lesion, while 11 patients (36.7%) have 2 to 9 lesions and only 3 cases (10%) have ? 10 lesions in different sites of their bodies. There were elevated high significant differences at the level of (P?0.01) when compared between the groups. And 21 cases (70%) have infected for ? two months, and the remaining 9 cases get their infection for > 2 months duration. There were increased high significant differences observed at the level of (P?0.01) when compared between the groups. Dry lesions recorded superiority in 20 (66.7%) of the CL cases, and other 10 (33.3%) have been diagnosed as a wet lesions. There were elevated high significant differences observed at the level of (P?0.01) when compared between the two types of the lesion. And The upper limbs were the dominant site of lesions in the CL cases, 15 (39.4%) of the cases had their lesions in one or both hands, followed by the lower limbs in 11 (29.0%) cases and the less frequent site of infection was the face in only 4 (10.5%) cases and 8 (21.0%) cases common lesions. The results showed obvious high significant differences at (P? 0.01) between the groups.4. For the tests of the autoantibodies, the anti - ds - DNA antibody was positive only in one patients (3.3%) with CL of the total (30) patients, while tests of the rest 29 (96.7%) were negative, while in VL of the total (30) patients, 9 patients (30.3%) were positive and 21 (70.0%) were negative. The anti - ds - DNA in leishmaniasis patients were highly significant at the level of (P?0.01) when compared between the study groups. As for the anti - nucleosomes antibodies, it was positive in 5 patients (16.7%) and negative in 25 (83.3%) among patients in CL, while in VL patients, 16 patients (% 53.3) registered positive and 14 (46.7%) their result werenegative, the anti - nucleosomes antibodies in leishmaniasis patients were highly significant at the level of (P?0.01) when compared between the groups study. No score was recorded for anti - SmD1antibodies in CL patients, no one was positive 0 (0.0%) and all the 30 patients (100.0%) gave negative result for this antibody, while in patients with VL, the result showed 4 patients (13.3%) gave positive and 26 patients (86.7%) were negative, the anti - SmD1antibodies in leishmaniasis patients was significantly different at the level of (P?0.05) when compared between the groups. While the anti - SSA/Ro60kD and anti - SSA/Ro52kD, in VL patients, 9 patients (30.0%) scored positive results and 21 of the patients (70.0%) were tested negative for anti - SS - A/Ro60kD, but 7 patients (23.3%) were positive and 23 of the patients (76.7%) were tested negative for anti - SS - A/Ro52kD. While in patients with CL, no one scored positive (0.00%) and 30 of the patients (100.0%) were negative for anti - SS - A/Ro60kD, whereas one patient (3.3%) gave a positive result and 29 of the patients (96.7%) were negative for anti - SS - A/Ro52kD. About anti - SS - B/La we found that 19 of the patients (63.3%) were scored positive result for this antibody in addition to 11 patients (36.7%) who were negative in VL patients and 4 of the patients (13.3%) have those antibodies and 26 of the patients (86.7%) haven’t these antibodies in CL patients respectively. The anti - SS - A/Ro60kD, anti - SS - A/Ro52kD and anti - SS - B/La in leishmaniasis patients were highly significantly different at the level of (P?0.01), when compared between studied groups.5. VL cases showed a significantly different distribution of anti - nuclear antibodies (ANA) in compare with CL cases, especially; in Anti - Ku antibodies 24 (80%), anti - Mi - 2 antibodies 21 (70%) and anti - SS - B/La antibodies 19 (63.3%) respectively.6. The results of anti - nuclear antibodies level in patients with leishmaniasis like; anti - ds DNA, anti - nucleosome, anti - SmD1, anti - PCNA, anti - SS - A/RO 60, anti - SS - A/RO 52, anti - CNP - B were in high significantly different at the level of (P?0.01) and level (P?0.05) when compared between the groups, while the other autoantibodies like; anti - histone, anti - ribosomal P0, anti - Sc170, anti - U1 - snRNP, anti - AMA M2, anti - J0 - 1 and anti - PM - Sc1 showed no significant differences (P?0.01) between the investigated groups.7. The mean value of anti - cardiolipin IgG antibodies was increased substantially with highly significantly differences (P?0.01) in VL patients as compared with control group (8.123 vs. 1.959), also as compared with CL patients (8.123 vs. 2.402).

The study was performed to see the impact of the pregnancy stages; sex factors of the fetus; body mass index; the mother's age; and residence for pregnant women, in the concentration of : certain blood components (Hb, PCV, WBC); blood sugar; cholesterol; estrogen, progesterone and testosterone hormones; and (TSH, T3, and T4 hormones. The study included (90) women at different stages of pregnancy, and the number of pregnant women at every stage was (30), ranged their ages from (15 - 40) years. A sample of (10) ml blood was taken from the surveyed women. The serum was separated by the common methods of separation, and conducted thereon desired examinations, The outcomes were as follows : - 1. Superiority of the first and second stages of pregnancy significantly (P<0.05) in the concentration of (Hb, PCV), compared with the third stage. 2. Increasing the total count of white blood cells and the concentration of blood sugar and cholesterol significantly with the progress of pregnancy stages. 3. Increasing progesterone hormone concentration significantly with the progress of pregnancy stages, while the concentration of estrogen hormone decreased in the middle stage of pregnancy, and increased significantly in the first and third stages, whereas there were no significant differences in the concentrations of testosterone hormone during the different stages of pregnancy. 4. The concentration of TSH and T3 hormones were decreased significantly with the progress of pregnancy stages, while the concentration of T4 hormone was increased in the first and last stages of pregnancy.5. Superiority of male pregnancy significantly compared with the female pregnancy in the concentrations of Hb and PCV ratios during the first and second stages of pregnancy, while the opposite happened in the third stage.6. Superiority of male pregnancy significantly compared with the female pregnancy in the total count of white blood cells during the first and third stages of pregnancy.7. Superiority of male pregnancy significantly compared with the female pregnancy in the concentrations of blood sugar, while the female pregnancy surpassed significantly in the concentrations of cholesterol compared with the male pregnancy during all the pregnancy stages. 8. Superiority of female pregnancy significantly compared with the male pregnancy in the concentration of estrogen hormone in first stage, while the opposite happened in the third stage, while the male pregnancy surpassed significantly compared with the female pregnancy in the concentrations of testosterone hormone during second and third stages, as well as superiority of female pregnancy significantly compared with the male pregnancy in the concentration of progesterone hormone during the first and third stages of pregnancy, while the opposite happened in the second stage.9. Superiority of female pregnancy significantly compared with the male pregnancy in the concentrations of TSH hormone during the first stage of pregnancy, while the opposite happened in the third stage. while Superiority of male pregnancy significantly compared with the female pregnancy in the concentrations of T4 hormones during the first and second stage of pregnancy but the concentration of T3 superiority all pregnancy stages.10. A significant decrease in the values of Hb and PCV with increasing the body mass index during the second stage of pregnancy while the opposite happened in third stage of pregnancy.11. Increasing the total count of white blood cells significantly with increasing the body mass index in the first stage of pregnancy, while the opposite happened in the last stage of pregnancy. Increasing the concentration of blood sugar with increasing body mass index in first and second stages of pregnancy but concentration cholesterol decreasing significantly with increasing the body mass index.12. Decrease the concentrations of estrogen hormone significantly during first and second stages of pregnancy with increasing the body mass index for pregnant women, while a significant increase appeared in the concentration of progesterone hormone with increasing the body mass index during the second stage of pregnancy, and the opposite happened during the first and third stages. Testosterone hormone increased significantly with increasing the body mass index for pregnant women during first and second stages of pregnancy 13. A significant increase appeared in the concentrations of TSH hormone at pregnant women with decreasing the body mass index. while a significant increase for the concentration of T3 in first stage and T4 hormone increase at pregnant women during all stages of pregnancy with increasing the values of body mass index.14. No significant differences in values of Hb and PCV during the first and second stages of pregnancy for all ages, but the small ages surpassed significantly compared with the old ages during the third stage of pregnancy. while The total count of white blood cells decreased significantly with the progress of pregnant women's age during all pregnancy stages.15. The small age groups for pregnant women increased significantly in the concentration of blood sugar during the first stage of pregnancy, while they decreased significantly during the second stage of pregnancy.while Age did not affect significantly in the concentrations of cholesterol during the first stage of pregnancy, while the old age groups decreased significantly compared with the first and second age groups) 32 - 24), (23 - 15) during the second and third stages of pregnancy.16. The concentration of Estrogen hormone increased significantly with the age progress during the first and third stages of pregnancy compared with the second stage, while the concentrations of progesterone hormone decreased significantly at old ages during the first and third stages of pregnancy.The concentration of testosterone hormone was not affected significantly during the last stage of pregnancy for all ages, but it decreased significantly during the second stage of pregnancy compared with the first stage of pregnancy for all ages.17. A significant increase showed in for the concentration of TSH in first and the last stages while decreased significantly the concentration T3 and T4 hormones with the age - progress at all stages of age.18. No noteworthy impact for residence of pregnant women in all stages of age, cause its impact is very little on all the qualities covered in the present study.

Atotal of 155 sample from different clinical source has been collected during the period from October - 2012 to March - 2013, these include 20 samples from vaginal smear, 8 samples from saliva and 6 samples from human milk.The results of primary isolation, Laboratory diagnosis and biochemical test showed that 34 isolates has bee identified as L.salivarius.Ahigh precent of isolation has been carried out from human milk which was 40%. The ability of all isolates to produce gelatinase and biofilm has been detected and the results revealed the ability of some isolates to produce gelatinase and biofilm. Ahigh percent of gelatinase production has been detected in L.salivarius isolated from milk sample (50%), while alow percent of gelatinase production was 0% in L.salivarius isolated from saliva. The results of optical density of biofilm produced by L.salivarius isolates from milk which was 100% higher than it in isolates from vaginal and saliva which was 85% and 75% respectively. All isolates shows antibacterial effect against some Gram negative bacteria, the diameter of inhibition as between (2 - 8), the results showed the ability of 4 selective isolates of L.salivarius to produce bacteriocin in which the Rf valve of precipitate bacteriocin was (0.42 - 0.6) compard with leaky bacteriocin hich was (0.57 - 0.8), also leaky bacteriocin as more activity against G - ve bacteria than precipitate bacteriocin. The result of plasmid profile in L.salivarius revealed the presence of megaplasmid in all isolate except one which had one megaplasmid and one small plasmid. Bacterial conjugation between L.salivarius that produce bacteriocin and had megaplasmid which used as adonor cell with E. coli Jm 109 as a recipient cell showed transferring of megaplasmid from donor to recipient cell and the transconjugant cells showed high anti - bacterial effect due to bacteriocin production against G - ve bacteria. The result of amplification of Sal P gene encoding salivracin P by PCR confirmed that all isolate had no Sal P gene in there genetic materials which revealed that these isolates had another type of bacteriocin rather than Salivracin P.

المراتب التصنيفية للنباتات البرية من ذوات الفلقتين في منطقة صدور - ديالى Wild Dicots Plant Taxa of Sudoor - Diyala Province

المستخلص: This study examined the current survey of the vascular plants of dicotyledon wild during the study period (2013 - 2012) In the area of Sudoor - Diyala, the study was based on the 774 samples of plants with their duplicates as collected by The Researcher. All of these collections have been cacched in the Iraqi herbariums. To be specific there are 186 species which relate to 133 genus and 43 families. All these, have been scientifically classified with thier local and common Iraqi or arabic names.Besides, their duration and economic importance (medical, toxic, nutritional or forage, artificial, harmful, aromatic, ornamental, fuel plants or other uses). Moreover, their geographical distribution in the districts of Iraq and thier geographical existence in neighboring countries to Iraq (Saudi Arabia, Kuwait, Turkey, Iran, Syria and Jordan) , and the study results statistics have shown that the vast majority of the collected species are Herbal Plants totalling 164 species out of 179 species in all.This, in fact, can be ascribed to the impossibility of txonomizing 7 plants species for the incapacity to obtain their flowers or fruits. As for the shrub species it amounts to 13 species where as the number of woody species of trees is 2 only. As for the economic plants and their significance, let s mention the fact that the number of plants used as forage amounts to 86 species, the medical plants are 83 species, the toxic plants fall into 43 species, the ornamental plants are 23 species, the industrial plants are 14 species, the weed plants are 11 species, the aromatic plants are of 6 species, and the plants used as fuel are of 4 species. It also appears that the majority of the plant in the area of study is widespread in the various districts of Iraq, i.e. the number of such plants amounts to 110 species, however, there are plants of medium spread in the districts of Iraq, i.e. the number of such plants amountsto 54 species.There still are some plants whose geographic distribution has no been identified in the districts of Iraq and their number is 15 species, and as for their geographic extension into the neighboring Countries, these plants amount to 116 species in Saudi Arabia, 84 species in Turkey, 81 species in Iran, 79 species in Kuwait, 69 species in Syria and 26 species in Jordan. Furthermore, the species of plants collected perviously and have not been found during the period of study amount to 32 species and these relate to 13 families.The shrinkage of the vegetation cover in the area of Sudoor is attributed mainly to the drought conditions and the wind soil erosion which the area has undergone in the previous years. Besides, there are some other reasons including the overgrazing, the expansion of agriculture and the unstudied projects of construction, which have resulted in the disappearance of natural plants in the area.

The study aims at estimating some physical and chemical characteristics of water raised from the North Refineries Company / Baiji and can be used to irrigate some crops after treatment with a number of physical methods. It also aimed at estimating some heavy elements and their impact on the growth of plants that have been studied (tomato, eggplant, sweet pepper, hot pepper). The region from which samples have been brought of the area was Albu Juwaree village that is located in the city of Baiji and adjacent to the company. Besides, it occurs near wide agricultural areas. After estimating some physical and chemical characteristics of water, soil, and the proportion of oil waste, qualities of plants were studied as well as the assessment of (carbohydrates, proteins) and some of the heavy elements and their effects on the growth of those plants.The results showed that the water of industrial waste led to a reduction in the proportion and natural growth of plants. The most affected seeds were the seeds of sweet pepper, where the total percentage of germination was(0%) when infected %)100) and the least affected seeds were the seeds of tomato, where the total percentage of germination seeds was (80%) when water is contaminated (100%). The treatment by filtering has achieved the best germination of seeds of tomato and sweet pepper, where the ratio was (100%). It turned out that contaminated water has prevented the natural growth of those plants in respect to the number and the size of leaves, the length of roots and the weight of fresh and dry leaves. The methods of physical treatment showed that lightening (25%, 50%, 75%) made to the contaminated water led to the removal of the significant effects, especially when lightening was (75%).The results indicate that there is no significant differences in the lengths of the roots of tomatoes and eggplants, except for the root of hot and sweet pepper.While the heavy elements, which was part of the study in this research, beginning with cadmium was at its highest value at the treatment by filtering and less value in (100%). Through the study it was found that the percentage of lead in all studied plants were (0.00) ppm. The Results showed that the contaminated water led to the reduction of the proportion of carbohydrates with the increase of pollution(%100), where the least proportion of carbohydrates was at the treatment by filtering. The results also showed a decrease in protein concentration with the least proportion at lightening and less value in. (25%)The results showed that the water content of contaminated industrial heavy metals studied (cadmium - lead - copper - zinc - nickel) has decreased at all treatment when treated by filtering, as well as for the remaining elements, except lead, which was (0.00) in all plants and all lightening ratios.The results of this study show that treatment of contaminated water with industrial oil waste by physical methods led to minimizing the negative impacts of such water in reducing the percentage of germination and the reduction below the natural growth compared with non - treatment water and showed that the best way of treatment for the best growth of plants were lightening with (75%) and treatment by filtering. The best response to the treatment was tomato and the most resistant to pollution were (tomato and eggplant) and the most affected by contamination and least resistant was sweet pepper.

This technique considered a modern technique in this field.Physical, chemical and biological characteristics of the manufactured sludge were determined and compared with organic fertilizers (I.O.F) imported from republic of Estonia (Available in local markets).T.R.D technique induced dewatering of the treated sludge at ratio48.5 - 61.5% and producing highly sterilized organic fertilizers which was free of pathogenic organisms(bacteria, worms and eggs) with high chemical characteristics comparing with those imported from Estonia. Manufactured organic fertilizers M.O.Fs have allow acidity pH ranged between 7.5 - 7.7 ,. electrical conductivity at range 1630 - 1873, organic matter at ratio 4.56 - 5.35%, with a moderate concentrations of Pb, Cd, Zn.The concentration of N and K was 1.8, 5.96% respectively while the concentration of phosphorus are 350 ppm. Three levels of M.O.Fs were used for corn plants(5, 10 and 20ton/acres). Results showed that all these levels significantly induced increasing for some physiological and morphological characteristics of corn plants compared with those treated by I.O.Fs or control plants. The vegetative dry weight of corn plants fertilized by M.O.Fs were 23.95gm/plant compared with 16.3 and 5.3 gm/plant for plants fertilized by I.O.Fs and control respectively. (M.O.Fs) induced significant increase in nitrogen concentration compared with plants fertilized by I.O.F and control while the concentrations of Pb, Cd, Zn were not affected by using of M.O.Fs on the other hand Pseudomonas aeruginosa and Escherichia coli were contributed in reducing and removing some of pollutants from the sludge at three incubation periods (30, 60 and 90 day). These two species caused significant decrease in pH and EC of the sludge, P. aeruginosas showed the highest removing ratio of nitrogen (93.1%). The cooperation of the two species caused high removing ratio for the Total organic carbon(87.72%) at 60 days and organic materials (90.68%) at 90 days of incubation also showed high removing ratio for phosphors 100%) at 90 days of in cubation.) These two species also caused high removing ratio for pb, Cd and Zn at30 days and P. aeruginosa was more effective in removing Pb, Cd and Zn from the sludge then E. coli.

Aspergillus niger Has been Isolated from these sample with 56% appearance in soil & 48% in sptum of TB pateints.these isolated were examined micro and macroscopically. purified Fungi was culture on potato dextrose broth, after incubation period polysaccharide antigen of A.niger cell wall was prepared for isolated from soil and TB patients suptum. Molish, protein and glucose test to provide that these antigen are polysaccharide, then immunuization of local rabbit of Orcyctalagus conninculus age 3 - 5 months & 1 - 1.5 Kg for males only (3 animals for each antigen) After the immunization period (one month) some of local and systemic immune response parameters (cellular and humoral) to test animals were studied and compared with control animals which immunized with normal saline. The results of study showed that the polysaccharide antigen isolated from these two strains lead to stimulate systemic humaral immune response which had been studied by using direct agglutination test for appendix immunoglobulin passive haemagglutination test (both were used to determined antibody titer), radialimmunodiffusion test in order to determine level of concentration of immunoglobulins (IgG, IgM) and complement part (C3, C4). where The results of direct agglutination titer of animals immunized with polysaccharide antigen 128 and 1 for control animals and heamagglutination tests titer of animals immunized with polysaccharide antigen serum (2560). These results were higher compared with control group titer (10) and this is also true for immunoglobulin and concentration of IgG, IgM for immunized animals compared to control one. In addition to that The concentration of C3 and C4 had been increased in immunized animals compared to the control. cellular immunological response had been measured by using rabbit Neutrophil Elastase Kit. The eresult show an increase in the level of phagocytosis in animals immunoized with polysaccharide antigen isolated from A.niger cell wall of TB pateints 0.37±0.03 pg/dl while decreased in animals immunoized with polysaccharide of soil A.niger 0.72294±0.25548pg/dl compared with control animals 0.6±0.16386 pg/dl. on the other hand the humaral adaptive immune response had been identified by measuring cytokine IL - 2, IL - 10 in serum rabbit, the level of IL - 2 in rabbit immunoized with polysaccharide antigen soure TB patients and soil is 5.4129±1.08979 and 4.2641±0.62997 pg/dl respectively compared with control animals 3.9327±0.55587 pg/dl. The level of IL - 10 had been dropped for immunized animals with A.niger of TB pateints and from soil 4.8762±1.15104 and 8.2632±4.31933 pg/dl while the control animals having the highest level 10.2576±5.23356 pg/dl among the groups. IgE concentration measured significant difference at p>0.05 in immunized animals of A.niger in both TB pateints and soil 1.1701±0.05811 and 1.0770±0.19355 ml/Iu compared with control where IgE0.8723±0.0849ml/Iu. Miotic index of bone morrow immunized and control animals show mean difference is signification at p>0.05.where the result demonstrate that the polysaccharide antigen fissed the bone marro cells compared to controlled one. In order to identify the viability of antigen in protection. challenge dose test made by injection animals with 108 spore/ml of A.niger conidia which prove their protection in immunized animals while the control animals undergo many morphological and behavioral changes after 5 - 7 days of their injection.I addition that the size of lung and spleen increased when compared with immunized one. The histological culture of lung and spleen of challenge test animals in order to identify the ability and speed of their body to evadicate and prevent infection, display that A.niger coloni appeared for control animals (6 rabbit) while disappeared in culture of immunized one. Skin test also performed to experimental animals which indicate that polysaccharide antigen of A.niger interact with hypersensitivity test of rabbit, where the level of late hypersenetivity increased clearly with propability of p>0.05 with the highest level after 24 hours of beginning test compared to controlled one.

المستخلص: بحثت الدراسة جمع 100 مسحة من اطفال مصابين بالتهاب اللوزتين الحاد والمزمن ممن راجعوا استشارية الانف والاذن والحنجرة في مستشفى اليرموك التعليمي للمدة مابين كانون الاول للعام 2013 ولغاية اذار للعام 2014. وكانت نتيجة الزرع المختبري موجبة في 67 مسحة منها وبالا | In this study 100 swabs were collected from infected children with acute and chronic tonsillitis who attended at Al - Yarmook Teaching Hospital (Eear Nose Tonsils consultation clinic) from December 2013 until March 2014. The result of laboratory culture were positive in 67 samples. Depending on their cultural, morphological and biochemical characterization of bacterial isolates : (37.31%) of them were identified as Streptococcus pyogenes bacteria and the diagnosis is confirmed by the use of Remel Rapid STR System. Whereas (34.33%) belong to S.parasanguinis, (11.94%) S.mitis, (11.94%) S.oralis and (4.48%) S.thoraltensis were identification of them are confirmed by using Vitek - 2 System also. As well as Sensitivity test for S.pyogenes cultures for some of the antibiotics done and the results revealed that all cultures were sensitive to tetracycline and chloramphenicol drugs 100%, while it was different in their sensitivity for other drugs. According to age (2 - 13) years revealed the highest percentage of infection for both male and female, however the percentage of acute and chronic tonsillitis was higher in males than females. In this study, during investigation of the antagonist action of lactic acid bacterial isolates against these pathogenic bacteria, results revealed that the method of L.acidophilus discs gave a high inhibition zones with a diameter of 11.3 mm, while L.fermentum discs yielded a high inhibition zones with a diameter of 7 mm 24 hrs following incubation in comparison with well diffusion method by using suspension of L.acidophilus produced a high inhibition zones with a diameter 7.25 mm 48 hrs after incubation. L.fermentum suspension produced a high inhibition zones with 10 mm diameter 24 hrs following incubation. Also the study included measurement of the inhibition activity for bacteriocins produced by L.acidophilus bacteria against the pathogenic bacteria S.pyogenes on nutrient agar by well diffusion method in which results revealed stability of the bacteriocins effects under different PH (4, 5, 6) with percent (100, 60, 50)% respectively for 24 hrs at higher stability and the highest stability of bacteriocins during PH was 4 with percent 100%, while it lost a lot of its activity with acidic PH less than 2 and basal pH more than 8. During the study the effect of Nacl, Kcl and MgSo4 with different concentrations (1 - 5%) with constant inhibitory effect for bacteriocins produced by L.acidophilus against pathogenic S.pyogenes, The result revealed that Nacl had little effect in inhibition zone with 1&2% concentrations. The salt MgSo4 and Kcl showed reduction in the inhibitory activity with 1, 2, 3% concentration, however the higher concentration of salt caused great reduction as 5% concentration led to loss of inhibitory activity for bacteriocins completely.Also this study showed light on the inhibitory effect of probiotics suspensions against the adhesion property of S.pyogenes after treated with L.acidophilus and L.fermentum.where the Result shown that L.acidophilus inhibit the adhesion of S.pyogenes with percent 68.92% either L.fermentum inhibit the adhesion of this pathogenic bacteria to epithelial cell with percent 30.28%. The study is consisted of showed the inhibitory action for suspensions of L.acidophilus and L.fermentum on biofilm formation by S.pyogenes, it was noticed the action of L.acidophilus in the side more than from the action of L.fermentum. During the study of the effect of suspension and filter of L.acidophilus and L.fermentum on the production of Hemolysin enzyme by S.pyogenes, it was noticed that the ability of suspension belong to L.acidophilus and L.fermentum to reduce the diameter of hemolysis zone which was beta type more than the ability of filter L.acidophilus and L.fermentum to reduce of the hemolysis zone which was beta type.

دراسة نسجية مقارنة بين عضلات الصدر والارجل في نوعين من الطيور الطائرة وغير الطائرة في عمرين مختلفين Comparative Histological Study Between Pectoralis And Leg Muscles In Flying And Running/Walking Birds In Two Different Ages

المستخلص: تناولت هذه الدراسة عددا من العضلات الهيكلية في نوعين من الطيور الطائرة (الحمام) وغير الطائرة (الدجاج). العدد الكلي للطيور المستعملة 30 طائرا, 15 من الدجاج و15 من الحمام تمت دراسة بعض الخصائص الفسلجية والنسيجية للالياف العضلية الحمر والبيض والوسطية وحساب | This study deals with a number of skeletal muscles in two types of birds ; flying (pigeon) and running (chicken) types. The total number of the studied birds was 30; 15 were chicken and 15 were pigeons. Some of the physiological and histological characteristics of the muscle fibers (red, white, and intermediate) , the percentage of fibers diameter in the studied muscles, and the change noted in the muscle weight with advancing age had been calculated. The species of the chicken in this study was Gallus domesticus , while the species of the pigeons was Columba livia domestica. The muscles that is used in the study were : pectoralis muscle, femortibialis, triceps, biceps brachii, extensor carpi radialis muscle, and gastrocnemius muscles in two age groups of birds; (3 - 6) months and (6 - 12) months in order to know the changes in the weights, numbers, diameters, and sizes of the muscle fibers that occur with advancing age. The aim of this study is to identify the three types of the muscle fibers their role in the muscle movement and the regions in which there is specific type rather than others. The results had shown that the skeletal muscles in birds consist of heterogenous mixture of the three types of muscle fibers (red, white, and intermediate) , and the white muscle fibers are the predominant type in the pectoralis muscle of both types of birds, and the size of white muscle fibers in the pectoralis muscle in the chickens in the first age group was 73.8%, and in the second age group was 82.9%. While in pigeons, the size of white muscle fibers was 75.5% in the first age group, and 75.4% in the second age group. In addition, the present study deals with the relationship between the muscles weights and the age of the bird in that the muscles show increased weight with advancing age in both types of birds and there were significant differences in muscles weight in both age groups (p?0.05), while the triceps muscle did not show significant difference regarding weight between the two age groups in the same type of birds. The results of the study also show the differences in the diameter of the muscle fibers, that is there was continuous increase in the diameters with advancing age and show significant differences (p?0.05) , but regarding pectoralis muscle there was no significant differences in diameters with advancing age in both types of birds. The results of the study also show that the pectoralis muscle was the largest muscle in the body of the bird, and the ratio of its weight to the total body weight was relatively large.

The second factor was the plants density with three levels (66666, 80000, 100000) plants/h - 1 and the third factor three varieties of sunflower (Shemoos, Akmar, Euroflour) , and the important results obtained were : 1. The highest density level (100000) plants/h - 1 gave the highest results in most of the characters studied which were, head or disk diameter, plant yield, yield (ton / h - 1), fertility percentage, oil percentage in seeds, oil yield(ton / h - 1), and protien yield (ton / h - 1).2. Level of 150 Kg/ h - 1 of NPK fertilizer was the best in most of the characters which were head diameter, plant yield, yield (ton / h - 1), oil percentage, oil yield (ton / h - 1), protien percentage and protien yield (ton / h - 1).3. Shemoos variety exceeded other varaieties in leaf area, leaf area index, stem diameter, head diameter, 1000 seed weight, plant yield, yield (ton / h - 1), seeds number in head, oil yield (ton / h - 1), protien yield (ton / h - 1) , but it gave the highest number of days to flower and mature.4. The interaction (Shemoos variety X zero NPK) gave significant highest mean in number of days from planting date to 75% flowering.The interaction (Akmar variety X 150 Kg NPK / h - 1) gave the highest values in stem diameter, head diameter, lodging percentage, but the interaction (Shemoos variety X 300 Kg NPK / h - 1) gave the highest values in leaf area, leaf area index, and number of days from planting date to maturity.5. The interaction (Shemoos variety X 66666 plants per hectar) gave significant differences in number of seeds per head , 1000 seeds weight, one plant yield, and yield (ton / h - 1). The interaction (Akmar variety X 100000 plants/ h - 1) gave significant differences in fertility percentage.6. The interaction (150 Kg NPK / h - 1 X 66666 plants/ h - 1 ) gave the highest significant differences in all quality characters studied. 7. The interaction (Shemoos variety X150 Kg NPK / h - 1 X 100000 plants/ h - 1) gave the highest significant results in seeds yield, oil yield and protien yield.

دراسة التاثير الاليلوباثي لنبات اليوكالبتوس Eucalyptus sargentii في انبات ونمو بعض نباتات الزينة The Allelopathic Effect of Eucalyptus Sargentii On Germination And Growth of Some Ornamental Plants

المستخلص: اجريت تجربتين, حقلية ومختبرية, لدراسة التاثير الاليلوباثي لمسحوق الاوراق الجافة او الطرية لنبات اليوكالبتوس ومستخلصاتها (المستخلص الايثانولي, الزيت, التربينات, القلويدات والفينولات) في الانبات وصفات النمو الخضري والزهري ومحتوى بعض العناصر المعدنية, السكري | Two experiments were carried out, field and laboratory experiment, to study the allelopathic effect of dry or fresh leaves and their extracts of Eucalyptus sp. on four ornamental plants; Calendula officinalis, Tagetes patula, Mathiola incana and Asteriscus graveolens Less. The two experiments were conducted at the field of College of Agriculture/Al - Qadisiya University during the period from 31/10/2012 to 14/3/2013. For the field experiment, dry and fresh leaves of Eucalyptus were used at the rate of 0, 2, 3, or 6 g dry leaves/Kg soil or at the rate of 0, 4, 8, or 12g fresh leaves/kg soil. Plant height, changes in height during plant life time - course, number of branches, number of flowers, and flower diameter were measured. In addition, chlorophyll content in leaves, anthocyanin in petals, dry weight, nitrogen percent, potassium and phosphorous content in leaves were also determined. For the laboratory experiment, ethanol extract, oil, terpenes, alkaloid, and phenols extracted from Eucalyptus leaves at different concentrations were used. Seed germination, coefficient velocity of germination, plumule and radical length, sugar, protein, melanodialdehyde, glutathione and proline content were evaluated. The results were as follow : 1. Ethanolic extract was negatively affect the percent and coefficient velocity of germination in addition to plumule and radicle length. The reduction in these parameters was greater at the highest concentration of the extract, especially in Calendula officinalis. 2. Treatment with oil extracted from Eucalyptus leaves caused a significant reduction in percent and coefficient velocity of germination, plumule and radical length. 3. Terpenes, alkaloids or phenols treatments at different concentrations resulted in significant reduction in percent and coefficient velocity of germination, plumule and radical length. The reduction was increased as the concentration of the treatments increased. 4. Plant height decreased significantly due to the treatment with dry or fresh Eucalyptus leaves, the reduction in plant height increased as the concentration of the treatment increases in all plants except Asteriscus graveolens plant which showed that the small concentrations of both treatments. It was close to ward in an increase in plant height. 5. Number of branches also significantly decreased when ornamental plants treated with dry or fresh Eucalyptus leaves; the Calendula officinalis plant was the most affected. 6. For the changes in ornamental plants height, as a result of treatment with dry or fresh leaves of Eucalyptus, during life time - course, it was clear the growth curve was close to the S - shape growth curve with obvious significant differences for most treatments compare to control. 7. Dry weight percent was significantly affected in all ornamental plants when they treated with dry or fresh Eucalyptus leaves, If decreased with the concentration of the treatments increased. 8. It was obvious that treatment with dry or fresh Eucalyptus leaves resulted in significant reduction in flower number and flower diameter. Number of flowers decreased as the concentration of the treatments increased. on the other hand, flower was diameter increased as the concentration of the treatments increased, but in both cases it was less than the control. All one obvious that reducing significant in flower diameter, It was reducing great in low levels. 9. Chlorophyll content was also decreased in leaves, while anthocyanin content in petals was increased when the ornamental plants treated with dry or fresh Eucalyptus leaves. 10. Nirogen percent, phosphorus and potassium content in leaves of the four ornamentals decreased when they treated with dry or fresh Eucalyptus leaves. 11. Using terpenes, alkaloids and phenols caused significant increase in sugar content in leaves of the ornamentals, reaching its highest values at the highest concentration of the terpenes. For protein content, it was gradually decreased as the terpens, alkaloids and phenols concentrations increased in Calendula officinalis. In Tagetes patula, protein content was noticeably increased with the increasing in concentrations of the treatments. 12. Malondialdehyde, glutathione and proline content increased significantly in Calendula officinalis and Tagetes patula plants when they treated with terpenes, alkaloids or phenols. 13. Interaction between treatments concentrations and kind of plants had significant effect on all parameters measured.
