Visceral leishmaniasis (VL), or kala-azar, is an infection of the reticuloendothelial system, Fatalities due to leishmaniasis are associated with visceral disease. the Leishmaia donovani is a causative agent for this disease. In the current study, white male mice of the Balb /C strain were experimentally infected with the leishmania donovani promastigotes and were then treated with a Viscum extract and compared with the Pentostam. The aim of this study was to evaluate the sensitivity and specificity of polymerase chain reaction (PCR) in the detection of Leishmania DNA in blood samples of infected mice. as well as, evaluation the ability of Viscum album extract to treatment the visceral leishmaniasis. The genetic study gave excellent results in the diagnosis of infection throughout the treatment period compared to the positive and negative control . Using the specific LdI primer , the 700bp of the parasite was diagnosed. This Broad band was shown in the positive control samples, in the pantostam treatment groups, and the muscular injection with viscum extract in the first 15 days and in the oral dosage group in the first 20 days of initiation. While the band did not appear in any other. The current study has shown promising results in the use of V. album in the treatment of visceral leishmaniasis and also gave impressive results in the diagnosis of infection PCR.

The study include 225 specimens that were collected from patients attended Tikrit General Hospital from mid of Septembar to mid December 2016. The specimens included the swab from: burn, wound, otitis media ,pharyngitis, and urine The specimens were incubated on to mannitol salt agar which is considered as selective and differential media for the genus Staphylococcus the results showed that 100 isolate (44,5%) grown on the medium. According to the phenotypic characteristics and tests biochemical they were Staph. aureus ,Staph. Saprophytis , Staph. sciuri, Staph. Xylosus Staph. lentus Staph. haemolyticusi Staph.c aseolytic
The ability of isolates to produce nitrate reductase, hemolysin, urease, DNAas were test . The antiboiotics were tested for resistance to 10 antibiotics. Some spceics showed high resistance to PenicillinG (94), Tobramycin (40%), Amikacin (39%), NitroFurantion (38%) Tetracyclin (36%), ,Novobiocin (24%), Trimethoprim (23%), Gentamycin (13%), Chloromphenicol (10%), Imipenem (3%).,
The inhibitory effect of biological extract of the Staph. species the pylogenetic effect has built of the concentrations of 100,150,250 mg / ml showed an inhibitory effect against types of Staphylococcus bacteria.
It was also found that the higher the concentration of the extract, the greater the inhibitory effect.
The results showed that Staph.aurea bacterial was the most affected by fungal compounds if the highest inhibition dimeter in concentration was 250 mg / ml 26 mm in the case of extract of Trichoderma koningii, whereas the inhibition rate in the same case the concentration was 24 ml. in the case of extract of Trichoderma viride.

The aim of this study was to investigate the accuracy of widal test by compared with enzyme linked immunosorbent assay (ELISA) as standard method and for this purpose 150 blood samples were pulled from patients suspected infected with typhoid fever coming to Azadi Teaching Hospital and Children's Hospital in Kirkuk Governorate from 1-09-2016 to 1-11-2016, and 20 sample of blood were pulled from healthy people considered as a control group. The sample tested by tube titration method of Widal test and also by using ELISA test (antibodies IgM and IgG). The results showed that the percentage of infection in patients with typhoid fever were 74% (111:150) when diagnosed by widal test, and IgM antibodies increasing in ratio 32.6% (49:150) Which indicate as acute phase. IgG antibody recorded increasing with ratio 2.7% (4:150) this indicate as chronic phase. Both types of Ab (IgM and IgG) increasing in ratio 12% (18:150). the accuracy of widal test showed that the Positive and negative predictive value were 49.45%, 87.17% respectively, While the percentage of sensitivity and specificity were 92.95% and 43.03% respectively. We conclude from this study that widal test have high sensitivity for diagnosis typhoid fever but its haven't good Specificity and it must be replace with more accurate testing such as ELISA .

PCOS is one of the most common endocrine disorders among women between 12 and 45 years of age, affecting 5-10% of women. The patients were included in the current study based on the criteria of Rotterdam in the diagnosis of polycystic ovarian syndrome with at least two of the following three criteria: menstrual cycle disorder, chemical criteria for high levels of androgen, detection of polycystic ovary using ultrasound (10 or more cysts of 2-10 mm in diameter). Sixty (60) patients were diagnosed with the syndrome and 30 healthy women were considered as control groups aged between 16 and 46 years.A number of criteria have been adopted to exclude patients who have had previous ovarian surgery as well as women taking contraceptives, steroids and herbal medicines that affect ovarian function for at least two months. The study was conducted at the Azadi Teaching Hospital in the city of Kirkuk for the period from October 2016 to February 2017.
Blood collected for all participants on the second or third day of the menstrual cycle. Body mass index (BMI) was calculated and prostate specific antigen (PSA) level and the level of sex hormones such as Anti-mullarian hormone(AMH),Luteinizing hormone(LH),Follicular stimulating hormone(FSH),Testosterone hormone(T) as well as Luteinizing hormone/Follicular stimulating hormone(LH / FSH) ratio were determined. The relationship between PSA and all studied variables was investigated after dividing the study sample into three age groups A (16-25), B (26-35), and C (36-45) years. Each age group included 30 patients with PCOS and 10 women as a control group).The results showed a significant increase (p <0.05) in the level of the PSA, AMH, LH, T and LH / FSH ratio, conversely the level of FSH was significantly reduced (p <0.05) when comparing women patientswith the control group. Correlation results showed a positive correlation between the PSA level and the values of all the studied variables except for FSH, which was inversely correlated with serum PSA in PCOS patients and for most age groups except for category C where AMH showed a negative correlation with PSA. The results also indicated a significant correlation between PSA and T, LH, and LH / FSH ratio for all ages groups. PSA can therefore be considered as a biochemical marker for androgen activity changes in patients with PCOS.

Beta particle has a huge applications in industry, medicine and research fields. The aim of the present study is to calculate the mass attenuation coefficients (μ / ρ)β_ and the range of Rβ- for negative beta particles within the energy range (0.257-2.25) MeV for 13Al and 79Au respectively. Use the equation of Kisse and Vertes to calculate the mass attenuation coefficient and the Tabata equations to calculate the range of electrons in the same elements. All the equations were adopting by the program (Visual studio professional 2012). The results we obtained were compared with the available experimental one, indicating that they are in good agreement, thus supporting the possibility of applying them to other elements effectively. As for the range it is a function of the negative beta particle energy and then the range in the aluminum is greater than the of the values in gold due to the electronic density of the gold element.
