ABSTRACT
Epithelial tumours are the most common ovarian neoplasm in postmenopausal age group. Yolk sac tumour is a type of germ cell tumour which is common in younger age group. Occurrence of such tumour in postmenopausal women is extremely rare and not more than 55 cases have been reported so far in English literature. Often in such cases an association with benign or malignant epithelial tumours have been described. We report a strange case of Yolk sac tumour in a 57 year old postmenopausal lady who presented to us with chief complaints of abdominal distension and early satiety. She underwent exploratory laparotomy with presumed diagnosis of carcinoma ovary. Upon exploration she had extensive disease with peritoneal nodules and metastatic deposits over small bowel mesentery. Debulking surgery in form of total abdominal hysterectomy with bilateral oophorectomy, infracolic omentectomy and stripping of anterior peritoneum was done. Postoperative histopathological examination showed presence of high grade adeno carcinoma of left ovary with omental metastasis. On immunohistochemistry cells were immunoreactive for cytokeratin, Glypican 3, SALL 4 and negative for EMA,CK-7,CK-20,PAX8 and OCT 4.The clinical picture was consistent for Yolk Sac tumour. Postoperatively she was planned for chemotherapy with BEP. Her pulmonary function testing was suggestive of severe restrictive disease. She received one cycle of EP. One month later she developed ascites and melena and succumbed to her disease
ABSTRACT
Objective: The primary objective of the present investigation is to evaluate the antihyperglycemic activity of the 50% ethanolic extract of the Tecomella undulata Seem. (TUE) bark in the streptozotocin induced diabetic rats. Methods: Single intraperitoneal injection (i.p.) of streptozotocin (60 mg/kg body weight) was used for induction of diabetes is wistar albino rats. The induction of diabetes was confirmed after 3 days after STZ injection and rats with fasting blood glucose levels greater than 200 mg/dl were considered to be diabetic used in the experiment. TUE at a once a daily dose of 250 mg/kg, and 500 mg/kg, p.o. along with glibenclamide 600μg/kg, p.o. was also given for 21 days. On the 21st day rats from all the groups fasted overnight and the blood was collected from the puncturing the retro orbit of the eye under mild ether anesthetic condition. The oral acute toxicity studies did not show any toxic effect till the dose at 2000 mg/kg. Results: The statistical data indicated that the different doses of the TUE significantly decreases the level of fasting blood glucose, total cholesterol, triglycerides, low density lipoprotein and increase high density lipoprotein in STZ induced diabetic rats. This result indicated that T. undulata extract can protect pancreatic β-cells from STZ-induced damage which is confirmed by the results of the histopathological examination of the pancreas. Conclusion: Our investigation has clearly indicated that the bark extract of Tecomella undulata Seem. showed remarkable antihyperglycemic activity due to its possible systematic effect involving in the pancreatic and extra pancreatic mechanism. Moreover, the antihyperlipidemic activity was exerted possible by lowering the higher level of lipid profile.
