Effects of Crocin on The Pituitary-Gonadal Axis and Hypothalamic Kiss-1 Gene Expression in Female Wistar Rats
Background: Saffron (Crocus sativus L.) is traditionally used as a spice for coloring and flavoring in cooking in some countries. One of the main component of saffron is Crocin. Recent researches have shown Crocin has various pharmacological effects. The aim of this study was to assess the effect of Crocin on the Pituitary-Gonadal Axis and Kiss-1 gene expression in hypothalamus and also ovarian...
متن کاملRole of Nitric Oxide and ATP-Sensitive K+ Channels in Regulation of Basal Blood Flow and Hypercapnic Vasodilatation of Cerebral Blood Vessels in Rabbit
Background: The mechanisms underlying cerebral hypercapnic vasodilatation are not fully understood. Objective: To investigate the role of nitric oxide (NO) and ATP-sensitive potassium (KATP) channels in basal blood flow regulation and hypercapnia-induced vasodilatation in rabbit cerebral blood vessels. Methods: The change in cerebral blood flow was measured by a laser Doppler flowmeter in 18 Ne...
متن کاملThe effect of immobilization stress on the HPG axis (hypothalamic - pituitary - gonad) hormones and the number of spermatogonia
Background & Objective: Stress has different effects on the living organisms. In this study the effect of immobilization stress the HPG (hypothalamic - pituitary - gonad axis) hormones secretion and the number of spermatogonia was studied in adult male rats Materials & Methods: 30 male rats were divided into 3 groups. The Control group: who were not exposed to any kind of stress, and two exper...
متن کاملRole of Local Nerves and Prostaglandins in Regulation of Basal Blood Flow and Hypercapnic Vasodilatation of Cerebral Blood Vessels in the Rabbit
The mechanisms underlying cerebral vasodilatation during hypercapnia are not fully understood. To examine the role of nerves and prostaglandins in the regulation of basal blood flow and in hypercapnia-induced vasodilatation in the cerebral blood vessels of rabbit.Cerebral blood flow was measured by laser Doppler flow-meter in 18 NZW rabbits anesthetized with sodium pentobarbital. Tetrodetoxin ...
متن کاملTHE SUBACUTE EFFECTS OF CADMIUM ON SEX HORMONES IN FEMALE RATS
Toxic effects of trace elements upon the hypothalamic- pituitarytesticular axis and sex hormones have been reported in recent years. It is generally considered that CdCl2 poisoning causes histopathological changes in the testicles of male rats. Little attention had been drawn to the possible toxic effects of CdCl2 on the ovary and female sex hormones. The purpose of the present study was t...
