المستخلص: بلغ العدد الكلي للعينات التي جمعت وفحصت للفترة من بداية شهر تموز 2007 الى نهاية شهر مايس 2008 (2345) عينة لكلا الجنسين مــن مستشفيات كركوك للتحري عن وبائية طفيلي المشــــــعرات المهبليـــــــــة Trichomonas vaginalis وبعض الجراثيم المسببة للامراض المنقو | A total (2345) specimens were collected & examined from both sexes, from the beginning of July 2007 till the end of May 2008 attending Kirkuk hospitals for epidemiological study of Trichomonas vaginalis & some sexual transmitted microorganisms. The vaginal examinations were done by gynecologist, two high vaginal swabs were taken from (250) women & a cervical swab from some women with vaginal discharge. General urine examination & blood group with Rh factor were performed for each woman with vaginal discharge. Direct microscopic examination, staining & culture of swabs were performed on different methods for diagnosis of Trichomonas vaginalis, followed to diagnose Candida albicans, Neisseria gonorrhoeae, Chlamydia trachomatis & Treponema pallidum as well as some other bacterial groups. The rate of Trichomonas vaginalis was (2.8%) & Neisseria gonorrhoeae (0.8%), while no Chlamydia trachomatis & Treponema pallidum recorded in this study. The highest rate of Trichomonas vaginalis was among the age group between 15 - 29 years (3.6%), the rate of Trichomonas vaginalis infection was higher among illiterate (5.7%) than educated ones. The highest rate of Trichomonas vaginalis was recorded among those with blood group O & Rh (+ve) (3.8%). The same result was found regarding other microorganisms in both sexes. Statistically the results were not significant.The rate of infections in females was higher than males in all infection except Neisseria gonorrhoeae was recorded highest rate in males(35%). The percentage of mixed infections with Trichomonas vaginalis was Candida albicans (1.6%) & B - hemolytic streptococcus (0.4%). The maximum infections rate in vaginal swabs were Staphylococcus aureus (42.3%) & lowest rate of Neisseria gonorrhoeae (2%). Regarding the distribution of microorganisms isolated from urine samples of females suffering from vaginal discharges, the highest rate of infection was Eschirechia coli (22.2%) & lowest rate of Neisseria gonorrhoeae (2%) respectively. The rate of isolated microorganisms from urethral discharge of males were Neisseria gonorrhoeae (35%) & Escherichia coli (5%). Antibiotics Ciprofloxacin & Amikacin showed good inhibition activity against all pathogenic microorganisms. Regarding the effect of different concentration of metronidazole & medical herbs to the Trichomonas vaginalis invitro, metronidazole showed clear effective inhibition at concentration (1.25%) during 24 hours. The inhibitory effect of Zea mays (both alcoholic & watery extractions) was greater than Apium graveolens & Foeniculum vulgare. At concentration (2.5% & 5%) of Zea mays in both extractions was almost identical to metronidazole. Six solvents were used by thin layer chromatography (TLC) in order to separate alcoholic & watery extraction of medical herbs, only three of them A, B & F gave good results in separating herbal extraction with differing in its component. By measuring relative flow rate (Rƒ) of all compounds that separated and determind. The chemical compounds of each herbal extract were established & included alkaloids, flavonieds, amines, pigments, oils, carbohydrates, phenols, purines & tanines.

المستخلص: تهدف الدراسة الحالية للتعرف على بعض الجوانب الفيزيائية والكيميائية والحياتية لمياه نهر دجلة ضمن مدينة تكريت ولمياه المخلفات السكنية في محطة المعالجة.جمعت العينات لمدة سبعة اشهر اعتبارا من شهر تشرين الثاني 2006 وحتى نهاية شهر ايار 2007 وبمعدل مرتين شهريا | The present study aimed to find out some physical, chemical and biological aspects of Tigris river passed in Tikrit - city, and population residence in the treatment unit.Samples were collected over the period of seven months during November 2006 to the end of May 2007 biweekly. Four stations were selected for sample collections over the distance of 25 km. Two stations were in Tigris river and two were in the treatment unit. The first selected station was close to the old water purification unit in Tikrit - city. The second station was selected at the treatment unit in AL - Dubaee before the mechanical treatment unit. The third station was selected at the treatment unit after the biological treatment. The fourth station was selected in Tigris river about ten km south of the treatment unit at AL - Dijla town. The study involved an investigation of some physical, chemical and biological aspects of Tigris river and the residence waste discharges to the river. This included air and water temperature, conductivity, PH, dissolved oxygen, BOD, Turbidity, total hardness, calcium and magnesium hardness, chloride, total alkalinity, nutrients (i.e., phosphate, nitrite, silica) , and the concentrations of heavy metals (i.e., cadmium and cupper). The biological factor included the total bacteria counts cultured on nutrient agar. Results of the study clarify the close relation between air and water temperature which varied (8.5 - 36) C0 and (9 - 27) C0 respectively. Conductivity values were relatively high and ranged (128 - 3530) microsemens/cm. River water almost was alkaline during the period of the study. PH values of the first and fourth stations were close in the river, although a value of 6.12 was recovered at station on during May. In all stations, PH values ranged (8.8 - 6.12). River water has a good ventilation, dissolved oxygen values ranges (8 - 11) mg/L at the first and the fourth stations, while these values were (0.1 - 1.34) mg/L at the second and third stations. Mean dissolved oxygen values pointed out the availability of good oxygen concentration for the continuity of living organisms which ranged (0.3 - 5.8) mg/L in Tigris river, while BOD values at the stations second and third were high and ranged (5.6 - 131.2) mg/L. Turbidity was high during April at the stations one and four and ranged (2.03 - 788) NTU in all stations. Total hardness in Tigris river was slightly low - very hardness and ranged (120 - 360) mg/L at the first and fourth stations, while these values were (180 - 480) mg/L at stations two and three.The high total hardness values coincided with the high conductivity values. Concentrations of calcium ions responsible on the calcium hardness ranged (211.4 - 120.7) mg/ L was higher than magnesium ions responsible for magnesium hardness range (5 - 265) mg/L.Records of chloride ions ranged (14.16 - 169.99) mg/L at all stations. However, chloride values at stations first and fourth were among the allowed world values and ranged (14.16 - 42.48) mg/L.Alkalinity values were due to the carbonate and bicarbonate and ranged (35 - 725) mg/L.phosphate values ranged (0.168 - 25.2) µg phosphor atom - phosphate/L. Low nutrient values recorded in Tigris river, while the highest values recorded at second station (treatment unit).Nitrite values fluctuated at all stations and ranged (0.078 - 14.778) µg Nitrogen atom - Nitrite /L. Silica values ranged (648 - 5961.6) µg silicon atom - silica /L. Heavy metals values (Cadmium and Cupper) clarify that, Cadmium were (un sensible), except one value (0.008) mg/L that recorded at November, and un sensible for Cupper.Results of the statistical analyses of all involved factors showed significant differences at stations first and second, and between the first and third stations as well as the fourth station. While there was no significant differences between the second and fourth stations. And no significant differences between stations first and fourth.Total bacterial counts indicated high bacterial counts, and the average of total bacterial count ranged (2.605X105, 5.44X108, 2.265X108, 2.385X105) / ml at the four stations respectively, so the Tigris river considered pollutant - very pollutant.

المستخلص: يستخدم الكلوروفورم على نطاق واسع في العديد من الصناعات مثل صناعة الورق والمطاط ومطافئ الحريق ومستحضرات التجميل ومواد التخدير. كما يستخدم كمذيب عضوي للعديد من المواد في المختبرات التعليمية والصناعية. وينتج الكلوروفورم من العمليات الايضية التي تقوم بها بعض | Chloroform is widely used in many industries, such as paper, elastic, fire extinguisher, cosmetics and anesthetic materials industries. It also used as an organic dissolvent for many materials in industrial and education laboratories. Chloroform is produced by The metabolism process of living organisms such as macroalgae and some fungus of highly organic matter soil. It can also be produced by process of water cholornation. Because of chloroform is widely used, and few studies achieved on cytogenetic level. Therefore The present study was conducted to identify The effects of chloroform on cytogenetic characteritis in laboratory mice.This study includes : 1 - A Study on Some Cytogenetic Indices For The Effect of Chloroform on The White Mouse.2 - Sperm abnormalities of male mice.The results of The present study showed that The chloroform has the ability to motivate chromosomal aberrations which were represented by (ring chromosom, chromatid break, and centromore break) in somatic cells in both males and females mice and in germ cells in males, The results revealed significant differences in The chromatid break and ring chromosome of both male and females mice, which injected with two concentrations (0, 025 & 0, 05 mg/kg) when compared with control group. It was found That there were asignificant differences in centromore break of females, injected with two concentrations of chloroform in comparison with control group, while non significant were differences observed in The males.Also the present study showed there were significant differences in The chromosomal aberration in The germ cells of males mice, injected with two concentrations (0, 025 & 0, 05 mg/kg) when compared with controlled group.The concentration (0, 05 mg/kg) was more influent in comparison, with The concentration (0, 025mg/kg). It was found that 30 days of injection is more influent in comparison with 15 day of injection, and males are more influenced than females.The present study recorded a significant differences in creating micronuclei in both male and female mice, injected by chloroform with a concentrations (0, 025 & 0, 05 mg/kg)in compared with control group.The result also revealed that The chloroform cause a significant decrease in The mitotic index of The somatic cells in both males and females, morever significant decrease in The mitotic germ cells of The injected males mice was found.An increase in The Blast index factor in The somatic cell in both male and female mice, injected by chloroform when compared with control group was similar result was recoded rgarding The Blast Index factor of The males germ cells. Regarding The sperm abnormality, the result showed significant differences in The sperm abnormality of males injected by chloroform with two concentrations (0, 025 & 0, 05 mg/kg) in comparison with The control group. The concentration (0, 05 mg/kg) was more influent than The concentration (0, 025mg/kg). Besides and the period 30 days of injection was more influent than the period 15 days.

المستخلص: تناولت الدراسة الحالية, دراسة مظهرية وتشريحية مقارنة لـ(10) انواع تعود لـ(9) اجناس من العائلة المركبة Asteraceae (Compositae) في العراق, كما وتبعت الاجناس قيد الدراسة الى عشيرتين Tribes : العشيرة الاولى : (Cardueae), وقد ضمت الانواع : (Arctium tomentosum, Ca | The current study dealt with the morphological and anatomical aspect that compared the (10) Species that followed (9) genera, These Species followed the family Compositae (Asteraceae) in Iraq. It also divided the genera under study to two tribes. The first tribe : (Cardueae), It included the Species : (Arctium tomentosum, Carlina vulgaris, Chardinia orientales, Cnicus benedictus and Notobasis syriaca). The second tribe : (Lactuceae), It included the Species : (Geropogon glabrum, Geropogon hybridus, Hedypnois cretica, Koelpinia linearis and Urospermum pecroides). The morphological study involved the roots according to the characteristics, the form and dimensions (the length and the diameter), the study of the stem by the character, the color and the indumentums, also the dimension (the high and diameter) it resulted good characteristics, enabled us to use it in isolation of the types. It is also discussed the leaf on the based of the quantifier and qualifier that involved the form of the leaf and the form of the peak and the base, the character of the blade margin and the epidermis. The study also high lighted the dimension of the blade (the length and the width), The morphological characteristics of the leaves have given a great Taxonomical value rather than the root and the stem. It also mentioned in this study the Inflorescences in general : the form and the diameter of the receptacle, the dimension of the inflorescence (length and width), and the characteristics of the phyllaries, the study of Achenes, the length of the beak, the character of the filaments that connected by the peak of the beak. The proper morphological characters of the Inflorescences made the contrastive among the characteristics of the Inflorescence in unique type. This great advantage is useful in the classification of the species. The anatomical study contains the study of the dermal tissue system that belong to the types under study, specially the stem, the leaf. It make clear the differences among the characters of the epidermis cells for the stem and the leaf (the upper and lower epidermises), It tackled the study of the Stomata at the leaf and the stem, and measure of the frequency at these members. It also discussed the fundamental and vascular tissue system of the root, the stem and the leaf through the study of their characteristics of the transversal sector. It is also studied the vascular bundles according to the thickness of the regions belonged to the xylem and phloem; the number of the xylem arms in each bundle and the number of the vascular elements in one xylem arm. The study involves the system of the veins into the leaf blade or that called (Venation), and the thickness of the veins and its course, the behavior of the vein's ends and the method of its contact with the leaf margin. In addition, the study dealt with the method of the joining veins the secondary by the primary and the third veins by the secondary. Thus, the study make clear the considerable advantages that distinguish the types each other. It is observed the characteristics of the leaf's venation is a constant character that depends upon to classify the species. At end of the study, It is used the results of the morphological and anatomical characteristics in comparison of the two tribes; Cardueae and Lactuceae that the studied species followed.

The samples were examined by double wet direct smear method to identify the trophozoite and cyst stages of Entamoeba histolytica. The results showed that (112) were infected with amoebic dysentery. The total rate was (20.74 %). (262) are males with a rate of infection (19.84 %), whereas, the number of females was (278) with an infection rate (21.58 %). The study showed an increase rate of infection among the rural population, it was (25.71 %), whereas the urban population rate was (16.6 %). The study covered all ages beginning from less than a year to 75 years old. A highest rate of infection was recorded by (10 - 19) years old, it was (29.4%). The study also, found out that a highest rate of infection was during school months, particularly during November (27.5 %). Examinations of complete blood picture which included Hemoglobin concentration (Hb), packed cells volume (PCV), white blood cells count (WBCc), and erythrocyte sedimentation rate (ESR) were done on all patients infected with amoebic dysentery. The results were compared with those of healthy ones (Control Group). The results showed significant differences between the two groups. According to the significant one (P < 0.05), it recorded a decrease (16.9%) in the (PCV) and (25.1%) in the (Hb) and an increase (241.8%) in the (ESR) and (51.5%) in the (WBCc) for those ones infected with amoebic dysentery if compared with the control group. Clinical biochemistry examinations were performed, on blood sugar (Bs), electrolytes such as Sodium (Na+), Potassium (K+), Calcium (Ca++), Magnesium (Mg++), liver functions tests : total serum bilirubine(TSB), tranceaminase enzyme(GOT, GPT), alkaline phosphetase (AlP), total protein (TP) and albumin (Alb). The results showed that there are significant differences between persons infected with amoebic dysentery and the healthy ones according to the significant level (P < 0.05) in these examinations. The study showed a decrease(21.6%) in the (Bs) mean concentration, (16.8%) in the(K+) mean concentration, (5.8%) in the(Ca++) mean concentration, (4.5%)in the (Mg++) mean concentration, (10.5 %) in the (Na+) mean concentration , (17.2%) in the (TP) mean concentration and(12.2%) in the (Alb) mean concentration and increase (83.7%) in the (Alp) mean concentration, (52.1%) in the(TSB) mean concentration, (81.1%)in the (GPT) mean concentration, (59.9%)in the (GOT) mean concentration and(22.8%) in the (globulin) mean concentration in the persons infected with amoebic dysentery compared with the mean concentrations in healthy ones control group.
