Germinative testicular cells and bone marrow mononuclear cells transplanted to a rat model of testicular degeneration.

The aim of this study was to evaluate the ability of rat mononuclear bone marrow cells to recover testis cell associations and multiplication in busulfan-treated rats, and to compare these data to germinative testicular cell transplant. The germinative testicular cells were obtained by the trypsin digestion method, and bone marrow cells were harvested from femurs and tibias, and purified using by Ficoll gradient. Cell transplantation was performed by the injection of cells through the efferent ducts into the rete testis in busulfan-treated animals.

Effects of subchronic exposure to radio frequency from a conventional cellular telephone on testicular function in adult rats.

Purpose: We investigated the effects of subchronic exposure to radio frequency emitted from a conventional cellular telephone on the testicular function in adult rats.

Materials And Methods: A total of 16 male Wistar rats at age 30 days were randomly divided into 2 groups, including experimental and control groups. The experimental group was exposed to radio frequency emitted from a conventional GSM (global system for mobile communications) cellular telephone (1,835 to 1,850 MHz) for 1 hour daily during 11 weeks.

Seminiferous epithelium of rats with food restriction and carbon tetrachloride-induced cirrhosis.

Objective: Analyze the changes in the seminiferous epithelium in rats with carbon tetrachloride-induced cirrhosis (CCl4).

Materials And Methods: Forty-eight male Wistar rats aged 45-50 days, weighing 150-180 grams were used. Twenty-two rats underwent CCl4-induced cirrhosis with CCl4 0.
