Objective This research aims to evaluate the preclinical meritorious and anticancer effects of Metformin in a Xenograft model of breast cancer. Methods This interventional trial was conducted during a defined period of 5 months (August 2016 January 2017). We used a Xenograft model of nude BALB/c mice. A sample size of 50 mice, allocated into two groups and designated as Group A and Group B for Metformin and negative control groups, respectively. The anticancer activity of Metformin has been evaluated by comparing the tumour volume, tumour weight, tumour regression ratio, percentage regression, and survival rate. Results Compared with the control group, Metformin can significantly reduce the progression of tumour in the Xenograft model of breast cancer induced by MCF-7. This is reflected by significant differences in tumour volume at the final follow-up ( p = <0.001). Our findings are further supported by a significant reduction of the tumour growth rate ( p = <0.001) and tumour weight ( p = <0.001) in the Metformin group than in the control group. Similarly, the total survival rate and tumour regression are more significantly correlated in the Metformin group. Conclusion This study demonstrates that Metformin can significantly reduce the tumour growth and can increase the survival rate in a Xenograft model of breast cancer.

Aim This research was designed to develop an animal model by inducing polycystic ovary syndrome (PCOS) with dehydroepiandrosterone (DHEA) and observe reproductive and morphological changes after treatment with vitamin D. Materials and Methods Thirty pre‐pubertal female Sprague–Dawley (SD) dams were recruited. The animals were distributed 10 each in control, PCOS and vitamin D‐treated groups. In control group 0.2 ml of sesame oil was given. PCOS group was administered DHEA by the daily dose of 6 mg/kg for 30 days. In vitamin D‐treated group, animals were injected 6 mg/kg/day DHEA daily and 120 ng 1, 25(OH) 2D3/100 g subcutaneously once a week. The occurrence of reproductive phenotypic PCOS was evaluated by estrous cycle, morphology and histological changes of ovary, uterus on light microscope. Results The results of this study showed significant weight gain, obesity, and estrous irregularity in PCOs group as compared to control and vitamin D‐treated group. Conclusion Administration of vitamin D (120 ng 1, 25(OH) 2D3/100) improved the cycle characteristics, reduced body weight and morphological features in PCOS induced animals. The results support the effect of vitamin D treatment for metabolic and reproductive characteristic features in PCOS females.

ABSTRACT… Objectives: Diabetes mellitus is very common disease; the oral hypoglycemic drugs are utilized for diabetes. In Asia therapeutic plants are extensively used for cure of widespread variation of illnesses. Objectives: To study the Therapeutic effect of mango seed extract on diabetes Mellitus. Study Design: A prospective study and longitude. Setting: This study was conducted at Jinnah Post graduate Center, Karachi. Period: From June 2016 to June 2017. Material and Methods: Mango seeds were taken out with ethanol and used for study. The antidiabetic action of mango seeds extracts were well-thought-out at 100 and 200 mg/kg b.wt. The antidiabetic effect of mango seeds extracts were matched with tolbutamide 500 mg/ kg b.wt. Result: The ethanolic extract of mango seeds (200 mg/kg) revealed major (p< 0.01) hypoglycemic outcome in fasted diabetic rats, when matched with normal control group. The mango seed extracts were significantly increased insulin level and decreased HbA1c levels at the dose level (100, 200 mg/kg) in alloxone encouraged diabetic rats. Conclusion: The ethanolic extract of mango seeds ensuring important antidabatic outcome compared to aloxone tempted diabetes in albino rats and its stimulating insulin production in pancreas of albino rats.
