Anti-Mullerian Hormone Levels Increase After Bariatric Surgery in Obese Female Patients With and Without Polycystic Ovary Syndrome.

This study was aimed to investigate the effect of weight loss by bariatric surgery on the level of anti-Mullerian hormone (AMH) in morbidly obese female patients with or without polycystic ovary syndrome (PCOS). This prospective study includes 70 females, obese, and fertile patients of reproductive age. All patients were evaluated to determine the changes in weight, body mass index (BMI), serum AMH, and other biochemical parameters at the end of six months. The mean levels of the preop and postop AMH were 1.66±0.87 ng/ml and 5.99±1.39 ng/ml in the PCOS group; 1.35±0.76 ng/ml and 6.23±1.47 ng/ml in the non-PCOS group, respectively. The postop AMH levels were significantly higher than the preop levels for both groups (p<0.001). There were significant differences in the level of glucose, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride, total cholesterol, hemoglobin A1c, HOMA-IR, insulin between preop and postop 6th month. A negative correlation was found between postop AMH and body weight in all patients (r=-0.337, p=0.031). Postop AMH levels were negatively correlated with postop BMI levels in the non-PCOS patient group (r=-0.408, p=0.043). No significant difference was observed between the PCOS and non-PCOS groups in terms of all the parameters examined. In conclusion, our study suggests that the significantly increased AMH levels by losing weight with bariatric surgery in patients with morbid obesity with and without PCOS may indicate the improvement of fertilization potential. It could be considered when evaluating fertility in patients with morbid obesity.

Apoptosis-inducing Effect of a Palladium(II) Complex-[PdCl(terpy)](sac).2H2O] on Ehrlich Ascites Carcinoma (EAC) in Mice.

BACKGROUND/AIM: New compounds for cancer treatment are needed due to persistenly unsatisfactory management of cancer. [PdCl(terpy)](sac)·2H2O] (sac=saccharinate, and terpy=2,2':6',2"-terpyridine) is a compound synthesized for this purpose. We investigated its anti-proliferative and pro-apoptotic effects on Ehrlich Ascites Carcinoma (EAC) in vivo. MATERIALS AND METHODS: 42 Balb-c female mice were subcutaneously (s.c.) injected with EAC cells (1st day) and then randomly divided into 5 groups: control (0.9% NaCl), complex (2 mg/kg), complex (3 mg/kg) cisplatin (4 mg/kg) and paclitaxel (12.5 mg/kg). On the 5th and 12th day animals were drug administrated. At 14th day, animals were sacrificed. Expression of cell death and/or cell cycle-related markers (Bcl-2, Bax, active caspase-3, p53, PCNA) and apoptosis were investigated immunohisto-chemically. Survival-related markers (Akt, GSK-3ß, IGF-1R, IR, IRS-1, p70S6K, PRAS40) were evaluated by luminex analysis. RESULTS: Expression of p53, PCNA, Bcl-2 was found decreased (p<0.001) and that of active caspase-3, Bax, and apoptotic cells was found increased (p<0.001) in all groups. The survival-related markers did not show any statistical difference in complex groups. CONCLUSION: The Pd(II)-complex seems to have a strong anticancer activity on EAC by inducing apoptosis via both suppression of proliferation and activation of apoptosis in vivo, similar to the effects of cisplatin and paclitaxel.
