objective(s) this investigation was conducted to evaluate the effects of diabetes on the structure and function of testicular tissue. materials and methods diabetes was induced in male adult rats by a single intraperitoneal injection of streptozotocin. body and testicular weight, hormonal analyses, histological and ultrastructural analyses were measured. results the body and testicular weights ...

Background and Objective: Sciatic nerve transection is characterized by a rapid wave of motoneuron death associated with progressive synaptic lesions. The purpose of this study was to evaluate the long term synaptic changes. Materials and Methods: This basic study was carried out on paraffin- or resin-em...

Background: The aim of this study was to use Japanese quail as an animal model to evaluate the effects of cadmium (Cd) on the ultrastructure and the activity of metallothionein (MT) in the liver and kidneys. Methods: One hundred male Japanese quails were randomly divided into two Cd and control groups in 2015. The first group received 100 ppm Cd for 60 days in their feed. The ultrastructural c...
