This study was designed to evaluate thyroid stimulating hormone (TSH) and thyroid hormones Concentrations. Setting of the present study was performed in Teaching Hospital in Erbil city - Iraq from 1st of October  2017  to 1st of  March  2018. A total of 433 female  were participated for blood tests to estimate  thyroid function. Only 323 (74.6%) cases showed overall variation in hormonal level and 110 (25.4%) cases were normal. According to educational statue most of cases were with Bachelor level (67%). Generally 291(90%) of cases were married. 52% of the cases were  41 to 45 age group and 14.2 % cases was  in both 26 to 30 and 31-35 age groups.
About 59 (18.3%) cases had high TSH level only 13 (4%) case is considered as hypothyroidism when examined by consultation and collaboration with senior physician, while  54 (16.7%)  cases had low TSH level  but  41(12.7%) cases were considered hyperthyroidism. The result shows that 4 (1.7%) case have high T3 level  and 52 (16.09%) case have  low T3 level. While 26(8.04%) case have high T4 level  and 61 (18.9%) case have  low T4 level. In conclusion, we believe that thyroid diseases are more prevalent in women in Erbil and hyperthyroidism patient was more than hypothyroidism.

One hundred blood samples and burn swabs from septicemic burn patients were collected over a period from July 2017 until may 2018 at Burn Center in Baghdad Teaching Hospital. The age of patients was between one year to sixty years and they were suffering from burn wound sepsis ,the highest number of patients was female among age group 20-29 years old. The highest frequent cause of burn was flame 78% and the least was chemical 1%, it was found that flame burn patients were more vulnerable to sepsis. The mortality rate among male 56%, females 48% and the highest mortality rate was 100% in the age group less than one year and more than sixty years, the least rate of mortality was 27% in the age group 10-19 years old. The number of septicemic patients 36 who is total body surface area (BSA) burned 30-39% and the mortality in this group was 16.6%, however the least number of patients was two of BSA 90-99% with mortality rate 100%. The most frequent aetiological agents isolated from the blood of septicemic burn patients was staphylococcus aureus 34(28.1) followed by Pseudomonas aeruginosa 25(20.7), Klebsiella pneumonia 13(10.8), Streptococcal pyogenes 10(8.3), Escherichia coli 8(6.6%) and Serratia marcescense, Acinnetobacter calcoceticus were 5(4.1) equally. The incidence of gram negative bacteria was much higher than gram positive bacteria in the septicemic burn cases, most  of septicemic attack occur during the first week of admission and especially on the 7th day of staying in hospital and above, and they were much more  likely to result from gram positive organism e.g S.aureus and S.pyogene. After the 1st week the septicemic attack was much more likely to result from gram negative organisms e.g. P.aeruginosa  K.pneumonia, E.coli, Serratia mercescense, Acintobacter calcoceticus, P vulgaris and P. rettger.

Cyclophosphazene and Polyphosphazene have been developed as a fire retarding material by increasing the number of bromine and chlorine atoms and adding azo moieties within the chemical structure. Four azo phenolic compounds with different numbers and places of substituted bromine and chlorine atoms were prepared. The cyclophosphazene and polyphosphazene were functionalized by the azo phenolic compounds. The functionalizing was done  by substituting three chlorine atoms from cyclophosphazene or one chlorine atom from polyphosphazene by the prepared azo compounds through hydroxyl group. (ratio Azo3:1Cyclophosphazoene, and ration Azo1:1 Polyphosphazene). The chemical structure of the phosphazenes were  studied  by IR, 1H-NMR and elemental analysis. The fire retarding efficiency of phosphazenes compounds for many trading constructional materials was examined. The efficiency of the new phosphazenes compounds was increased for both Cyclophosphazene and Polyphosphazene as a fire retardant.

Optimum total efficiency and output power were derived for Nd:YAG laser with symmetrical resonator configuration, taking into account a new interaction factor called spatial interaction efficiency factor. Under the assumption of the same pumping power and the same resonator losses, the results interacted a lower output power and higher lasing threshold provided that the mirror reflectivity was optimized as compared with a laser system that did not take the spatial interaction efficiency factor into consideration.

In the present research, a spectrophotometric method is suggested as an alternative to the gravimetric method used to find mishraq alum purity. The method is based on the complex formation between aluminium ion and either Chrome Azurol S (CAS) or Eriochrome cyanine R (ECR) to give colored products suitable for the determination of aluminium. The same reaction has been applied to the determination of fluoride in tablet, depending on the bleaching effect of fluoride on the formed aluminium colored complex. Statistical comparison of method has given satisfactory results

The results showed positive effects as a significant increase (P≤0.0001) in Adiponectin hormone with significant decrease in Leptin hormone in rabbit's serum that given oat seeds powder and also those treated with simvastatin drug, and insignificant increase in Estrogen hormone in this two groups compared with control group in contrast there is a negative effects as a significant decrease in Adiponectin hormone and Estrogen hormone concentration in ovariectomized rabbit's serum with significant increase in Leptin hormone concentration, while tend in ovariectomized rabbits given oat seeds powder to be in near with normal concentration in control, and ovariectomized rabbits group given simvastatin showed either significant or insignificant near with normal concentration in control. Experimental atherosclerosis by ovariectomy in females led to negative effects on biochemical criteria of blood serum as compared with control group, which was represented by significant increase in the concentration of Total Cholesterol (TC) and Low Density Lipoprotein-cholesterol (LDL-c), beside significant decrease in High Density Lipoproteins-cholesterol (HDL-c) and Paraoxonase enzyme (PON-1), in general treated rabbits with oat seeds powder led to positive willful for all precedent parameters.
Histological sections of aorta artery in ovariectomized rabbits showed atherosclerotic lesions between the muscle fibers in media of aorta in contrast with the normal structure of aorta in rabbits in control group. Ovaiectomy led to negative effects on histological features of healthy and overectomized rabbit's liver.

A total of 220 samples were collected from different sources of infection from the patients of Tikrit Hospital and Samarra Teaching Hospital who showed symptoms of infection, both sexes and different age groups for the period from April 2017 to January 2018. The results of the isolating showed that the number of samples that showed positive bacterial growth on the used media was 135 samples (61.4%),while 85 samples (38.6%) of total samples did not produce significant bacterial growth, The common bacteria isolates in our study were the highest number of isolates with a total of 111 samples and 82.2%, the uncommon bacterial isolates showed in 24 growth samples (17.8%). The results showed that Morganella morganii had the highest percentage of isolates by 3 isolates (12.5%), followed by Aerococcus urinae, Pseudomonas stutzeri, Micrococcus luteus with isolates (8.2%), for other species, only one isolate (4.2%) was obtained, All isolates showed an absolute sensitivity of 100% for Imipenem and 100% absolute resistance to 10 antibiotics,the results showed that both bacteria Kocuria kristinae, O. anthropi, have three virulence factors, Protease, Urease, β-lactamase, While the bacterial species Sphingomonas paucimobilis, Gemella sanguinis, Aerococcus urinae, Pseudomonas stutzeri, Pseudomonas fluorescens, gave a positive test result for the production of β-lactamase, Hemolysin, while Morganella morganii, Alloiococcus Otitis have two factor, Urease, Β-lactamase. As for the isolates Pantoea agglomerans, Kocuria rosea has shown its ability to produce only one type of β-lactamase β-lactamase.

This research was performed to isolate and identify the Microorganisms causing vaginitis and cervicitis and relationship of some risk factors with these infections. Two hundred and seventy high vaginal specimens were collected during the period from December 2012 until the end of May 2013, from pregnant and non- pregnant women of different ages, who had the clinical symptoms of vaginitis and cervicitis infections.
Isolation and identification results showed that (252) specimen (93.3%) were positive for microbial culture, these specimen distributed among (152) specimen (60.3%) appeared single bacterial growth, (13) specimen (5.2%) were mixed bacterial growth, (36) specimen (14.3%) mixed bacterial with candida growth and (51) specimen (20.2%) candidal growth only.
Gram positive bacteria formed the high percentage (63.8%) compared with Gram negative bacteria (36.2%). Staphylococcus spp. were the most isolate among Gram positive bacteria and E.coli were the most isolate among Gram negative bacteria. Candida albicans showed significant appearance among positive microbial cultures either as single or mixed with bacteria.
Results showed relationship between some risk factors with studied infections, it was found that almost all infections were in the married women, aged (20-50) years (93.3%) and the most infections in non- pregnant women (66.7%), in addition to the role of other diseases (such as UTI, diabetes) ,various contraceptive methods and other risk factors.

Due to the unavailability of the drinking water in Mosul city in the period between                      (2014-2017), people started digging wells in their houses to use it in daily life for consumption and irrigation. Forty well water samples were chosen for this study in living quarters (AL-Dubat, Adan, AL-Mouthana, AL-Noor, AL-Zhoor, AL-Jamiea, AL-Falah, AL-Baker). Some pathogenic bacteria were isolated and identified from well water digged in different areas in the left side of Mosul city and to study reconciliation to human consumption. Results showed that fifty-six bacterial isolates obtained included 21 of Escherichia coli, 10 of Aeromonas hydrophila, 8 of Pseudomonas aeroginosa, 7 of Pseudomonas florescens, and show two species ofKlebsiellabacteria, Klebsiella pneumonia and Klebsiella oxytoca 6 and 4 respectively.
Then the ability of these bacterial isolates to form biofilm was studied by using two methods; Tube method and Congo red method, isolates gave 100% positive results in its ability to biofilm formation by tube method. While by congo red Aeromonas and Pseudomons were unable to form biofilm.
Also the study included determination of antibiotic  sensitivity and resistance of bacterial isolates to different antibiotics as it is considered one of the important virulence factors , Results showed that there is variation in its sensitivity and resistance to these antibiotics.
