This study was carried out to investigate the role of both calcium chloride and Vitamin C in protection against the deterioration effect of sodium fluoride (NaF) exposure on thyroid function .Fifty adult male rats were used, which divided randomly into five equal groups, the first group: The animals of this group served as control group administrated distilled water orally by gavage. Second group: administrated NaF (5.2mg/kg.bw/day) orally by gavage. Third group: administrated NaF (5.2mg/kg.bw/day) + Calcium Chloride (20mg/kg.bw/day) orally by gavage. Fourth group: administrated NaF (5.2mg/kg.bw/day) + Vitamin C (100mg/kg.bw/day) orally by gavage. Fifth group: administrated NaF (5.2mg/kg.bw/day) + Calcium Chloride (20mg/kg.bw/day) + Vitamin C (100mg/kg.bw/day) orally by gavag . The treatment continued for 45 days. At the end of the experiment, animals were sacrificed under anesthesia. Blood samples were taken and the serum was separated for the study of the thyroid hormones, and tissue samples of the thyroid gland were taken for histological changes. The study showed a significant elevation in thyroid stimulation hormone (TSH), and a significant reduction in tri-iodothyronine (T3) and thyroxin (T4) hormones concentration in NaF treated group compared with control, however a significant improvement were recorded in above cited parameters in all treated groups. Histopathological study revealed hyperplasia include presence of large number of small follicles in NaF treated group whereas a significant amelioration were found in all other treated groups which appeared semi-normal compared with control group

A total of 60 one-day old Ross broiler chicks were used in this study. The birds were divided into four groups. The first group A was vaccinated against IBD with a Cevac IBD L vaccine at one-day old by intra-yolk sac method (lYS) with a dose of 0.5ml using a (1ml) syringe, whereas the second group B was vaccinated against IBD with the same vaccine at 14 days of age by drinking water method (DW). The third group C and fourth group D were considered as a positive and negative control respectively . On day 35, the birds were weight and killed to collect blood samples and lymphoid organs were removed and weight to study the effects of (lYS) rout on body weight , lymphoid organ weights and the humeral immune response to IBD vaccine which measured by ELISA test. The results showed significant differences at (P≤0.05) in body weight of group A, in addition significant (p<0.05) increase in the all lymphoid organs weight , Bursa of fabricius (BF) was 1.643 a ±0.066 in group comparison with other groups which had been recorded 1.102 b ±0.022, 0.850 c ±0.067 in group B and C respectively. Group B indicated that was a significant decrease at (p<0.05) in the weight of of spleen which was 1.102 b ± 0.022 in comparison to control groups. With regard to serological test, bird from group A recorded higher Ab titer 24038 a± 685 compared to those of other groups , and this increment was statically significant (p<0.05), however both group A and B revealed a53 significant differences( p <0.05) from the control groups. Generally the results indicated that intra-yolk sac method was highly effective rout of IBD vaccine administration

The oral use of pregabalin was evaluated in this study to reveal its effects on some hematological and biochemical parameters of laboratory mice. The animals of this study were divided into three groups (twelve mice each). The control group was fed on a standard ration. The first treated group (Pregabalin 1) were dosed orally with one ml of distilled water containing Pregabalin (20 mg/ml/mice/ day). The second treated group (Pregabalin 2) were dosed orally with one ml of distilled water containing pregabalin (40mg/ml/mice/ day). The experiment continued for two successive months. The results showed that the use of pregabalin caused a significant declination in R.B.C., HGB, HCT, W.B.C., M.C.V., MCH, and MCHC of both treated groups compared them with control group and the declination was more significant in (pregabalin 2) group compared with (pregabalin 1) group. The RDWCV, RDW-SD, and PLT increased significantly in both treated groups as compared with those of the control group. However, PCT, PDW and MPV were not affected by the use of pregabalin except the MPV of (Pregabalin 2) group was significantly less than that of (Pregabalin 1) but without a significant difference compared with that of control. The Fe++, and GLU decreased significantly in both treated groups compared with the control and they declined more significantly in (Pregabalin 2) compared with (Pregabalin 1). Both the TP and Ca++ did not affected by the use of pregabalin compared with the control group (P≤0.05)

The present study was designated to illustrate the morphological , histological and histochemical features of adrenal gland of local domestic pigeons (coulumba livia domestica) in Basrah province . Ten adrenal glands used in the study collected from Karrmat Ali Village, Iraq . Immediately after collection the adrenal glands were subjected for morphological histological and histochemical study. The study revealed that the pigeon have paired small glands located in the abdominal cavity at the anterior pole of the kidneys . The gland was elongated in shape and showed creamy or grayish in color. Histologically , the glands was unsheathed with thin fibro – elastic connective tissue capsule containing many blood vessels . The cortical tissues were arranged into two zones; peripheral (sub capsular) and inner (central). The cells of sub capsular are arranged in curved cord , each cord had polyhedral acidophilic cells. On the other hand, the histological examination of the cortex of adrenal glands contains autonomic ganglia associated with glandular capsule ,contains nerve cells and fibers. The inner cortical cells showed straight and curved cords in longitudinal sections, each composed of two types of cells acidophilc cells and chromaffin cells .The Histochemical study revealed presence lipids droplets in the gland , in addition to elastic fibers in the capsules and among the cells of glands .

Two hundreds of different food samples i.e. cream, beef meat, frozen beef meat, burger,cooked rice and minced rice were collected from local markets in Basrah city. The testedsamples of each food type were found to be contaminated with Bacillus cereus (B. cereus) in aratio of 36.36 % for cream, 26.47 % for beef meat, 50 % for frozen beef meat, 36.36 % forburger, 18.18 % for cooked rice and 51.51 % for minced rice. Mannitol egg-yolk agar (MYP)supplemented with polymyxin B sulfate is a selective media used for isolation. Identification ofthe isolate was done by detection of 16SrDNA and conformed by sequencing. Antimicrobialsusceptibility test was used for screening the isolates, which were resistance to tetracycline.Bacillus cereus isolates were resistance to tetracycline TE 30 mg/disc (100 %) in cream and (0%) in cooked rice. Polymerase chain reaction was used for detection of the presence oftetracycline resistance gene in the percentage 32 % and 44% for tet (K) and tet (L), respectively.

John's disease or paratuberculosis is a chronic mycobacterial infection that affectsruminants, adversely, leading to huge economic losses throughout the world. Theestimation of sero-prevalence and molecular confirmation of this disease in the cattlepopulation of south-Iraq were the objectives of this study. One of the diagnostic toolsused to detect an antibody in plasma samples was the Enzyme Linked Immuno-Sorbent Assay, indirect-ELISA was used to diagnose and estimate the sero-prevalenceof paratuberculosis in cattle. Out of 156 bovine plasma samples, 81 (51.9%) werepositive and this MAP-seroprevalence is not significantly connected to age or breedof cows (P>0.05). In this study, a PCR-based detection of IS900, distinct insertionsequences of MAP from the buffy coat of seropositive cattle (n = 81) were used as aconfirmative diagnosis. The positive PCR-based detection of IS900 was observed inanimals having high S:P% ELISA values (n=29 :35.8%).

Extraction of Amygdalin from apple seeds by alcoholic extraction procedure were doneand applied a high-performance liquid chromatographic (HPLC) procedure for quantification ofit to investigate extraction efficiency and (16) bacterial isolates ( 4 isolates of Staphylococcusaureus, 4 isolates of Escherichia coli , 4 isolates of Pseudomonas aeruginosa and 4 isolates ofStreptococcus pyogenes from skin infections samples are choose by accomplished of drugsensitivity tests as a multidrug resistant, the antimicrobial activity of methanolic extract ofAmygdalin from crushed apple seeds was tested against each group of four pathogenic bacteriaspecies of gram positive (Staphylococcus aureus and Streptococcus pyogenes ) and gramnegative (Escherichia coli and Pseudomonas aeruginosa) by well diffusion method, the resultsshown that plant extract gave antibacterial activity through the inhibition zone , but theconcentration of the raw material was more inhibited than the dilute substance concentration,inhibition of the substance was obtained on all types of bacteria were in Staphylococcus aureus,inhibition zone of substances concentrations (100 mg/ml, 50 mg/ml) were (40, 28 mm)respectively , in Pseudomonas aeruginosa inhibition zone of substances concentrations (100mg/ml, 50 mg/ml) were (50, 35 mm) respectively, in Escherichia coli, inhibition zone ofsubstances concentrations (100 mg/ml, 50 mg/ml) were (40, 25 mm) respectively, also thisresults showed that three types of bacteria above were inhibited in synergistic effect, whileinhibition zone of Streptococcus pyogenes in concentration 100 mg/ml was 30 mm and inconcentration 50 mg/ml was 20 mm.

In present study the effect of feeding frequency on some health aspects (biologicalparameters) of fingerling of common carp were investigated. Three groups of common carp(average weight4.31±0.1 g) designed with three feeding frequencies one meal a day (D1),two meals a day (D2) and three meals a day (D3) with three replicates of each treatment. Fishin experimental treatments were fed by 4% of body weight. No significant differencesobserved in Hepatosomatic Index, Gill Index and muscle ratio (Weight without Viscera andWeight without Viscera & Head) in all feeding frequencies, feeding one and two time perday were significantly higher than three times/ day in each of Kidney index and SpleenIndex. Intestine weight index was significantly higher in T2 and T3, Intestine Length Indexwas higher significantly in T3.

The present study was carried out in ewes to investigate the causes of dystocia andeconomic effect, reared in Basrah governorate (Basra – Iraq ) .The current study was started from August 2017 to May 2018 , and conductedon 60 ewes,1.5-10 years old. Animals were divided into two groups,First treated group: 40 ewes suffered from dystocia. and theSecond normal group: 20 ewes with normal parturition served as a healthy control.Ewes with dystocia were diagnosed on the bases of clinical inspection .The study showed that the ewes that suffered from dystocia have a low serumlevel of calcium compared with control group.

This study was designed to evaluate the ameliorating role of CoQ10 and DHEA and theircombination on norfloxacin induced maternal toxicity and fetal growth retardation in pregnantfemale rats and their fetuses. Twenty pregnant rats were divided equally into 5 groups, 4 animalsper each group as following: Control group (G1): 4 normal pregnant female received0.5ml/animal/day DMSO by using gastric gavages from 5th - 19th day of gestation. First treatedgroup (T1): 4 normal pregnant female received 400 mg/kg norfloxacin daily by gastric gavagesas a single dose. Second treated group (T2): 4 normal pregnant female received orally 400 mg/kgnorfloxacin once daily and after 1hour later injected daily with CoQ10 200 mg/kg IP. Thirdtreated group (T3): 4 normal pregnant female received orally 400 mg/kg norfloxacin once dailyand after 1hour later injected daily with DHEA 25 mg/kg IP. Fourth treated group (T4): 4 normalpregnant female received orally 400 mg/kg norfloxacin once daily and after 1hour later injecteddaily with combination of CoQ10 200 mg/kg and DHEA 25 mg/kg IP for the same period. Alldams were sacrificed at 20th day of gestation and their fetuses were collected and subjected to themorphological examinations. The obtained results showed that exposure to norfloxacin inpregnant female rats during gestational period from 5th -19th day demonstrate clearly increased inresorbed and stillbirth fetuses (dead fetuses at birth), and caused a significant decreased in fetalbody weight, fetal body length, fetal tail length, maternal weight gain and placental weight. It has been concluded that CoQ10 and DHEA prevented and treated morphological anomalies in ratfetuses. Therefore, CoQ10 and DHEA are potential therapeutic antioxidant agents againstfetotoxicity induced by oxidative stress generated by norfloxacin intoxication
