Objective
The aim of the present study was to investigate effects of resveratrol (RSV) over ovarian hyperstimulation syndrome (OHSS) in rat model.Materials and Methods
24 female Wistar rats (22 days old) were divided into four groups. Group 1 (control group; n = 6) received 0.1 ml intraperitoneal (IP) saline from days 22–26; group 2 (mild-stimulated group; n = 6) received 10 IU pregnant mare serum gonadotropin (PMSG) on day 24 and 10 IU of hCG 48 h later (day 26); group 3 (OHSS group; n = 6) was given 10 IU of PMSG for 4 consecutive days from day 22 and 30 IU hCG on the fifth day to induce OHSS; group 4 (OHSS + RSV group; n = 6) was treated the same as group 3, but received 60 mg/kg RSV 2 h before PMSG injection for 4 consecutive days and 2 h before the hCG injection on the fifth day.Results
Weight gain was highest in the OHSS group. Ovarian weights were lower in the treatment group than OHSS group. Peritoneal fluid VEGF levels were lower for RSV group compared to group 2 and 3. Total VEGF immunoreactivity was higher in OHSS group than group 1, 2 and 4.Conclusion
These results indicate that RSV is beneficial for prevention of OHSS by reducing the increases in body and ovarian weight and VEGF activity. These effects may be mediated by anti-inflammatory, anti-oxidant and anti-angiogenic capacity of RSV. 相似文献42.

Objective: Growth Arrest-Specific 6 (GAS6) is a vitamin K-dependent protein. Despite a similar structure to Protein S, it has no anticoagulant activity. An association between GAS6 and some diseases for adults has been reported. In the absence of prospective clinical studies of GAS6 in neonates, so far, the objective of this study is to obtain, for the first time, plasma GAS6 levels before and after vitamin K1 prophylaxis in full-term and pre-term newborns.Methods: 80 newborns (40 term and 40 preterm) were recruited for this study. Cord blood samples and peripheral blood samples 48?h after vitamin K1 injection were collected into EDTA-tubes. GAS6 levels were measured in platelet-poor plasma by ELISA.Results: Cord blood plasma GAS6 levels in preterm and term newborns were 9.07?±?5.30?ng/mL and 9.75?±?4.34?ng/mL, respectively. In response to vitamin K1 injection, GAS6 levels increased in preterm newborns (10.50?±?5.28?ng/mL) (p?.05), but not in term newborns (9.12?±?3.42?ng/mL, p?>?.05).Conclusion: This pilot study provided, to the best of our knowledge, the first report that GAS6 levels increased significantly after vitamin K1 prophylaxis in preterm newborns but not in term infants. This study may serve as a first step toward more extensive studies in neonates. 相似文献

Objective
Endometriosis is a chronic gynecological disease characterized by the growth of hormonally responsive, endometrial tissue outside the uterine cavity. The present study aims to analyze two vascular endothelial growth factor (VEGF) polymorphisms (−460 C/T and +405 C/G) in Turkish women with and without endometriosis. 相似文献44.
目的:探讨敲低PI3Kp85α表达对人乳腺癌细胞系MCF-7细胞生长的影响和机制.方法:用靶向PI3Kp85α的siRNA转染人乳腺癌细胞系MCF-7,使用Real-time PCR法鉴定转染PI3Kp85α表达水平;MTT法评价PI3Kp85α siRNA对乳腺癌细胞系MCF-7生长的影响;流式细胞术检测转染后细胞周期分布和凋亡;采用免疫荧光染色及Western blot方法观察IA型PI3K/AKT通路主要成员的表达.结果:Real-timePCR结果显示PI3Kp85α siR-NA转染导致PI3Kp85α表达下调;MTT结果显示PI3Kp85α siRNA转染抑制肿瘤细胞生长;流式细胞术检测可见PI3Kp85α siRNA转染组细胞周期存在G_0/G_1期阻滞而且凋亡率显著高于对照组与空载体组(F=19.255,P=0.002).结论:应用PI3Kp85α siRNA转染人乳腺癌细胞系MCF-7细胞,可抑制其增殖和诱导细胞凋亡,因此PI3Kp85α可以作为人乳腺癌基因治疗的候选靶点. 相似文献

OBJECTIVE: Although radio-frequency ablation (RFA) has been recently applied as a minimally invasive treatment option for renal cell carcinoma (RCC), indication of this modality remains a critical issue due to the lack of complete tumor destruction as well as the uncertainty of its long-term efficacy. We report the efficacy of RFA for nine carefully selected patients with RCC who had significant reason to avoid invasive surgical treatment under general anesthesia. METHODS: Radio-frequency ablation was performed under epidural or local anesthesia by ultrasound or computed tomography (CT) guidance in nine patients with biopsy proven RCC (mean diameter, 38 mm; range, 20-53 mm), who were at significant operative or anesthetic risk for invasive surgery. Follow-up enhanced CT scans or magnetic resonance images were evaluated every 3-6 months and an evaluation of metastasis was performed every 6 months. RESULTS: At a mean follow-up of 17 months, seven (78%) of the nine patients with renal tumor showed no tumor enhancement. The renal function of all patients was well preserved. All patients were able to continue undergoing their respective treatments for active diseases in other organs in parallel to the RFA treatment. No distant metastasis, urine leakage were reported and one case of temporary hematuria and one case of peri-renal hemorrhage not requiring blood transfusion were encountered. Intra-operative ultrasonography was useful in the real-time monitoring of the minimally excessive extension of ablation into the normal parenchyma. CONCLUSION: Radio-frequency ablation appears to be an effective and safe minimally invasive therapeutic option for selected patients with RCC who have reason to avoid invasive surgery under general anesthesia. 相似文献

目的 评价放射吸收法(RA)测量2、3、4指骨中节骨密度的精确度和准确性.方法 对19例尸体的双手,用铝制楔型标志物,分别进行了50 kV 400 mA和60 kV 300 mA两次X线照射,对每只手指的第二至第四节指骨的骨矿含量(BMC)和骨密度(BMD),以Au(指骨指数)为单位进行测量和分析.结果 对于BMC-AU来说,这种方法的精密度误差是1.0%,对于BMD-AU来说,精密度误差是0.6%.通过5 mm和6mm 酒精厚度所获得的X射线图可以观察到BMD-Au有2.0%到2.4%的降低,与对照组相比有明显的统计学差异(P<0.01).采用X射线吸收测定法得到的BMC-Au 和前臂的BMC有良好的相关性(r=0.887),并且在指骨的BMC-AU与骨灰重量之间也有较好的相关性(r=0.983).结论 放射吸收法(RA)测量外周骨骨密度具有较高的精确度和准确性. 相似文献

We surveyed a random sample (n = 75) of doctors and dentists at University
College Hospital, Ibadan, Nigeria. They were offered anonymous testing for
hepatitis B surface antigen (HBsAg), hepatitis Be antigen (HBeAG),
antibodies to hepatitis B core antigen (anti-HBc) and to hepatitis C virus
(anti-HCV), by enzyme immunoassay. The results suggest a high prevalence of
hepatitis B virus (HBV) with a high potential of transmissibility, as well
as a high prevalence of HCV infection. The majority of the doctors and
dentists use universal precaution for protection against viral hepatitis on
< 50% of the occasions when they carry out procedures on their patients.
Infection with HBV was associated with type of specialty (surgeons,
dentists) and lack of HBV vaccination (p < 0.05). After logistic
regression, these factors were independently associated with HBV infection
(p < 0.05). Sixty (80%) had not received prior HBV vaccination.
Unvaccinated personnel were more likely to be surgeons, dentists, < 37
years of age, and have fewer years of professional activity (p < 0.05).
After logistic regression, only fewer years of professional activity
remained independently associated with lack of vaccination (p < 0.05).
To reduce the occupational exposure of HBV, universal precautions must be
rigorously adhered to when the doctors and dentists carry out procedures on
their patients, and all health-care workers should be vaccinated with HBV
vaccine and the HCV vaccine, when it becomes available.
