Background: Infertility is unexplained in about 22% - 28% of infertile couples. Spontaneous pregnancy may occur in them. If did not happen, Expectant management will be via clomiphene citrate (CC) administration, intrauterine insemination (IUI), and IVF & ICSI. Aim: to assess the effectiveness of intrauterine insemination with mild controlled ovarian stimulation compared with expectant management in couples with unexplained infertility more than one year. Methods: 160 couples with unexplained infertility were selected, The couples were randomly divided into two groups: Group (A) “80 couples”: Intrauterine insemination (IUI) with mild controlled ovarian stimulation (combination of CC + hMG) using prepared semen and was performed 36 hours after hCG injection, Group (B) “80 couples”: Couples had no ovulation induction. They encouraged for timed intercourse in the most fertile days of female cycle guided by folliculometry for 6 months. Data were collected quantitatively, coded and analyzed using SPSS. The power of study is 80% and 95% confidence interval. Result: The pregnancy rate was calculated in both groups: In group (A) (IUI/COS): OPR (Ongoing pregnancy rates) was 27.5% and PR (pregnancy rates)/cycle was 8.6%. In group (B) (Expectant management): OPR was 25% and PR/cycle was 5.3%. Conclusion: Mild controlled ovarian stimulation CC + hMG with IUI offers no statistical significance in terms of pregnancy outcomes over expectant management in this study however significance in the response to stimulation.

Background: Transvaginal color Doppler sonography of the uterine artery has been reported useful for evaluation of abnormal uterine bleeding in peri-/post-menopausal women. It may differentiate physiological from malignant endometrial changes. Objective: Evaluating the endometrial thickness and uterine artery Doppler as an initial diagnostic tool to identify patients with abnormal endometrial pathology. Methods: This is a prospective case control study consisted of total 50 women with peri-(n = 35) and post-(n = 15) menopausal bleeding, with 20 women consisting control group (no bleeding) (peri-(n = 10) and post-menopausal (n = 10)). Double layer endometrial thickness and uterine-artery-Doppler waveforms were measured, with the latter being S/D ratio, RI and PI. These were related to histological findings (endometrial biopsy). Result: Patients with abnormal uterine bleeding (both peri- and postmenopausal) had a significantly higher mean endometrial thickness than the control women. Study group showed a significantly lower value of all Doppler indices (S/D ratio, RI and PI). In study group, patients with malignant endometrial pathology showed significantly thicker endometrium and significantly lower Doppler indices than those with benign pathology. Conclusion: The combination of endometrial thickness and uterine artery color Doppler pattern might predict uterine endometrial malignancy, although whether it can discriminate (screen) patients requiring endometrial biopsy is not evident. Further study is needed.

Objective Nephrolithiasis is one of the most common disorders of the urinary tract. The aim of this study was to examine a possible relationship between DNase Ⅰ/Ⅱ activity and E3 SUMO-protein ligase NSE2 in the sera of nephrolithiasis patients to evaluate the possibility of a new biomarker for evaluating kidney damage. Methods Sixty nephrolithiasis patients and 50 control patients were enrolled in a case-control study. Their blood urea, creatinine, protein levels and DNase Ⅰ/Ⅱ activity levels were measured by spectrometry. Serum NSMCE2 levels were measured by ELISA. Blood was collected from patients of the government health clinics in Kuantan-Pahang and fulfilled the inclusion criteria. Results The result indicated that mean levels of sera NSMCE2 have a significantly increase（P〈0.01） in patients compared to control group. Compared with control subjects, activities and specific activities of serum DNase Ⅰ and Ⅱ were significantly elevated in nephrolithiasis patients（P〈0.01）. Conclusion This study suggests that an increase in serum concentrations of DNase Ⅰ/Ⅱ and E3 SUMO-protein ligase NSE2 level can be used as indicators for the diagnosis of kidney injury in patients with nephrolithiasis.

Gallbladder disease is the most common non-obstetrical cause of maternal hospitalization in the first year postpartum. Many risk factors have been associated with gallbladder disease in pregnancy including body mass index, prenatal weight gain, prenatal physical activity, dietary fat, age, parity, a history of gallbladder disease and the number of previous pregnancies were significant factors related to new gallstones and biliary sludge formation in the pregnant group. The aim of this study is to evaluate the risk factors for gallstones formation in pregnancy and one year after labour. The study included 328 female patients (pregnant or postpartum) divided into two groups;patient group (164 patient) that are pregnant or postpartum patient have gallstones and control group (164 patient) that are pregnant or postpartum patient does not have gallstones. All patients were subjected to full history taking;especially about risk factors predisposing for gallstones, physical examination and pre-operative routine laboratory investigations and imaging as abdominal ultrasound study (U/S). Obesity, young age, history of gallbladder disease and use of estrogen and progesterone are the main risk factors that increase incidence of gallstones during pregnancy or one year postpartum. Use of vit C, iron, drinking coffee and practicing regular physical activity are considered protective factors.

S: A dichotomous key and descriptions of the species of pitcher plants recorded from bris forest at Jambu Bongkok is given. Three species of pitcher plants were recognized from the study area. They are Nepenthes rafflesiana, Nepenthes gracilis and Nepenthes mirabilis. These species can easily be identified by their morphological differences. Nepenthes gracilis differed from the other two species in having triangular stem, sessile leaves, winged leaf base, under lid surface of the pitcher sparsely covered with honey glands, inner pitcher cavity wall covered exposed digestive glands and very narrow peristome with the thickness of ≤ 1 cm. On the other hand, Nepenthes rafflesiana and Nepenthes mirabilis have cylindrical stem, stalked leaves, semi-amplexicaul leaf base, under lid surface densely covered with honey glands, inner pitcher cavity wall covered with overarched digestive glands and broad peristome with a thickness of ≥1 cm. Nepenthes rafflesiana can be differentiated from Nepenthes mirabilis by its infundibulate upper pitcher, ellipsoidal lower pitcher, inner pitcher wall cavity wholly covered with digestive glands whereas Nepenthes mirabilis have tublose-ventricose upper and lower pitchers, inner pitcher cavity wall of both pitchers partly covered with digestive glands.
