The hormones of the anterior pituitary.

Comparing various attributes of prolactin hormones in different species: application of bioinformatics tools

Prolactin is mainly secreted by the anterior pituitary and is able to stimulate mammary gland development and lactation in mammalians. Although prolactins share a common ancestral gene encoding, they show species specific characteristics and their efficiency may be different in various mammals. The importance of protein structures of all sequences of this hormone have been studied by various bi...

Sulpiride-Induced Hyperprolactinemia in Mature Female Rats: Evidence for Alterations in The Reproductive System, Pituitary and Ovarian Hormones

An investigation on body weights, blood glucose levels and pituitary-gonadal axis hormones in diabetic and metformin-treated diabetic female rats

Diabetes is a metabolic disorder which affects whole body systems including reproductive system. Diabetes is also a contributing factor to infertility. Metformin is one of the most common drugs to control hyperglycemia. In this study, 36 adult Sprague-Dawley female rats (170-210 g) were divided into 3 groups (control, diabetic and diabetic-treated by metformin). In second and third groups, diab...

Effects of Cypermethrin on Sexual Behaviour and Plasma Concentrations of Pituitary-Gonadal Hormones

Background Pyrethroids are commonly used as insecticides for both household and agricultural applications, and have recently been linked to endocrine disruption. Cypermethrin is a type П pyrethroid which is used widely throughout the world. The present study was aimed to investigate the effects of cypermethrin on the sexual behaviour and plasma level of pituitary-gonadal hormones of adult male ...

The 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...

Comparative studies on the pituitary hormones of vertebrates III. Effects of the pituitary hormones of the tunny, Makaira marlina, on the gonads of mice.

glands. From this result, they indicated that the precocious sexual maturity was caused in the mouse by anuran anterior pituitary substances. It seems to the author that there would be no reference available,concerning the response of mammalian gonads to anterior pituitary hormones of pisces. Hence, in this paper effect of the hypophyseal gonadotropic hormones of tunny(Makaira marlina) to the g...
