Tissue Residues and Ultrastructural Changes Induced by DDT in Chickens

Metabolic and Ultrastructural Changes Induced in Adipose Tissue by Insulin

The addition in vitro of insulin to rat adipose tissue (epididymal) produces marked metabolic changes which may be followed by measurement of the net gas exchange of the tissue. Using this method to monitor the metabolic action of insulin, concomitant observations with the electron microscope on the tissue have been made. These reveal that pronounced morphological changes are induced by insulin...

Ultrastructural Changes of Sheep Oocytes Follow Vitrification by Different Methods and In Vitro Maturation

Purpose: Our aim was determination of the sheep oocytes ultrastructural changes follow vitrification and in vitro maturation. Materials and Methods: Good quality isolated cumulus-oocyte complexes (COCs) were randomly divided into non-vitrified control, conventional straw, cryotop and solid surface vitrification groups. In the conventional and cryotop methods the vitrified COCs were plunged dire...

Ultrastructural Changes Induced by Imidacloprid in Male Albino Rats

In the present study, ultrastructural alterations induced by oral administration of imidacloprid over 4 weeks was assessed in rats. Forty eight male sprague dawley rats procured from NIN and divided into four groups. Group 1 given with basal diet, group 2 orally gavaged with 80mg/kg/day imidacloprid, group 3 was treated with vitamin C at the rate of 10 mg/kg b.wt/day and group 4 was treated wit...

Changes of The Uterine Tissue in Rats With Polycystic Ovary Syndrome Induced by Estradiol Valerate

Objective : Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders that can lead to irregular menstrual cycles and hyperandrogenism. Reduced levels of progesterone and increased estrogen in these women can perpetually stimulate the endometrial tissue of the uterus. In this study, the effect of PCOS induction was studied using estradiol valerate. MaterialsAndMethods Adult ...
