Triple Super Phosphate, TSP fertilizer, was applied @ 80 kg·ha^-1 as the source of phosphorous on six months old polybag seed- lings of Albizia chinensis, Albizia saman and Pongamia pinnta in nursery beds in Bangladesh. The effects of P-fertilizer on seedling growth and nodulation were comparcd to that of seedlings grown in unfertilized soil or in control at different harvesting intervals. The study revealed that, seedling growth was enhanced significantly with the application of P-fertilizer. The growth was found more pronounced in cases of A. saman and P. pinnata, whereas it was not noticeable and showed depressed growth in case of A. chinensis. The study also suggests that nodulation in terms of nodule number and size was also increased significantly with P-fertilization except in case ofP. pinnata, where higher harvesting intervals lowered the nodulation performance of that species

引用

Open Journal of Obstetrics and Gynecology 2022年第12期12卷 1279-1288页

作者： Hany Mahmoud Abd El Hamid Manal Abdel-Wanees Alsayed Hesham mohammed Hamed Shaimaa belal Department of Obstetrics and Gynecology El-Sahel Teaching Hospital Cairo Egypt Department of Obstetrics and Gynecology Faculty of Medicine Helwan University Helwan Egypt

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.

Doppler Study of Uterine Artery and Ultrasonography of Endometrial Thickness in Perimenopausal and Postmenopausal Bleeding

引用

Open Journal of Obstetrics and Gynecology 2022年第4期12卷 309-322页

作者： Shaimaa belal Manal Abdel-Wanees Al-Sayed Hany Mahmoud Abd El Hamid Hesham mohammed Hamed Department of Obstetrics and Gynecology Faculty of Medicine Helwan University Helwan Cairo Egypt Department of Obstetrics and Gynecology Al-Sahel Teaching Hospital Cairo Egypt

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.

比较了不同浓度无机肥料(尿素和重过磷酸钙)对四种农林作物(楹树、雨豆树、相思树和印度田菁)生物固氮和种苗生长的影响。种子萌发一个月后利用不同浓度肥料(尿素:40kg·hm-2,80kg·hm-2;重过磷酸钙:40kg·hm-2,80kg·hm-2;(尿素+重过磷酸钙)40kg·hm-2和(尿素+重过磷酸钙)80kg·hm-2)处理种苗。结果表明:中等浓度无机肥料促进了种苗的生长,但较高浓度无机肥料也不利于种苗的生长。当施加尿素时根瘤菌的数量大小明显受抑制,但随着增加磷肥(重过磷酸钙)根瘤菌的数量大小增加。本研究有助于农业人员利用无机肥料改善土壤提高农林作物的生物固氮和种苗生长。图2表6参33。

Open Journal of Obstetrics and Gynecology 2022年第11期12卷 1166-1175页

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.
