This study aimed to determine prevalence rate of Sudanese infertile women with hyperprolactinemia attended Reproductive Health Care Center. The selected period of the study started from 2005 to 2010. The data was obtained from the statistical records available in the center to determine the prevalence rate of target group .Prolactin, FSH and LH serum levels were determined using Enzyme Immunoassay Technique ( EIA). A total of 14129 infertile women attended the center during the study period, 4096 of them with hyperprolactinemia ( prolactin < 400 IU / L ) and a prevalence rate of 29% . Among the hyperprolactinemic subjects, 39.4% with FSH > 12.9 IU/ L and 12.2 % with LH > 9.6 IU/L Two groups were selected from hyperprolactinemic subjects. Group A which composed of 2333 (16.5% of total infertile women or 57% of hyperprolactinemic patients) were hyperprolactinemic with regular menstrual cycle . Group B which composed of 491 ( 3.5% of total infertile women or 12 % of hyperprolactinemic subjects ) amenorrhic hyperprolactinemic patients . In conclusion, high prevalence of infertile Sudanese women with hyperprolactinemia was observed . Prevalence of women with hyperprolactinemia associated with high FSH was more common compared to those with hyperprolactinemia and high LH. Higher prevalence of Infertile hyperprolactinemic women with regular menstrual cycle compared to infertile hyperprolactinemic women with a menorrhea was observed.

This is a case-control study conducted in Omdurman Military Hospital and Zenam Diabetic Center in Khartoum state, Sudan, during the period from March to June 2012. The study aimed to assess plasma levels of triglycerides, total cholesterol, HbA1C and body mass index (BMI) of 100 Sudanese patients with type 2 Diabetes mellitus. (49 males and 51 females) as a test group and 50 Sudanese healthy (non-diabetic) subjects (24 males and 26 females) as a control group. The test and the control groups were matched in term of age and gender. Plasma levels of triglycerides and total cholesterol were measured using Biosystem BTS- 305 spectrophotometer and commercial kits from Biosystem Company, Glycosylated Haemoglobin (HbA1c) for each sample was measured using Nycocard reader II and commercial kits from Nycocard Company. Statistical package for social science (SPSS version 11.5) computer software was used for data analysis. The results showed that the means of plasma levels of total cholesterol, triglycerides, HbA1C and body mass index (BMI) were significantly higher in test group compared to the control (P > 0.050).The study showed a significant weak positive correlation between HbA1C % and the plasma levels of both total Cholesterol (r = 0. 283, p = 0.028) and Triglycerides (r =0.288, p =0.026) of diabetic group. The study also showed a significant moderate positive correlation between the body mass index (BMI) and the plasma levels of total Cholesterol (r = 0.447, p = 0.000), and insignificant week positive correlation between the body mass index and the plasma levels of Triglycerides (r = 0.124, p =0.346) of the diabetic group. From the results of this study it is concluded that: Total Cholesterol, Triglycerides, HbA1C and body mass index in diabetic patients significantly increased when compared with non diabetic control subjects. Also there was a significant weak positive correlation between HbA1C % and plasma levels of total Cholesterol and triglycerides in diabetic group, Furthermore, there was a significant moderate positive correlations between body mass index and plasma levels of total Cholesterol in diabetic group. Moreover, there was an insignificant weak positive correlation between body mass index and Triglycerides.

Assessment of Qat Consumption on Blood parameters in Yemeni Individuals in Sana’a City – Yemen
Mansoor Mohammed Mansoor
This work was a cross sectional hospital based study aimed to determine the effect of Qat chewing on CBC parameters. The subjects were 328 (289 mals and 39 females) Qat chewers selected from adult Yemeni healthy individuals attending the blood bank in Police Hospital in Sanaa, with an age between 18-65 years. After obtaining informed consent from each participant, 5 ml of venous blood was collected into an EDTA container then Hb, PCV, RBC, WBC, Plts, MCV, MCH, MCHC, RDW and WBC differential count were measured using blood auto analyzer. The results showed that the means of Hb, PCV, RBC, WBC, Plts, MCV, MCH, MCHC, RDW, neutrophils, lymphocytes, monocytes and eosinophils were 15.63 gm/dl, 47.02%, 5.40×106cell/cmm, 6.40×103cell/cmm, 289.32 mm3, 84.61 fl, 28.61 pg ,32.83 g/dl, 14.32%, 49.93%, 38.83%, 6.70%, 4.28%, respectively. In regard to control, these results indicated that platelets count was significantly reduced (p? 0.05) while other CBC components were not affected by Qat chewing (p? 0.05). The results also showed that, the effect of Qat hat on CBC parameters in this study was not associated with duration of Qat chewing, the dose of Qat consumed or gender of the subject. Based on the results, this study concluded that, Qat consumption may predispose thrombocytopenia.
