Construction of an animal model of autism based on interaction between cerebellar histological, immunohistochemical, and biochemical changes in adult male albino rat.

Methods: Twelve pregnant female rats were divided into a control group and a valproic acid (VPA) treated group (injected intraperitoneally on embryonic day 12 with 600 mg/kg body weight of VPA). Neurobehavioral tests were conducted on the offspring of both groups. The cerebellum was studied by light and electron microscopy as well as GFAP and caspase-3 immunohistochemical staining.

Structural changes in testes of Streptozotocin induced diabetic rats and possible protective effect of royal jelly: light and electron microscopic study.

Diabetes mellitus (DM) is one of the most common metabolic diseases causing damage in many organs in the body including the testes. Royal Jelly (RJ) is one of the honey bee products that has antioxidant, anti-inflammatory and antidiabetic properties. This study was performed to evaluate the changes in the microscopic structure of the testes in Streptozotocin (STZ)-induced diabetic rats, and the possible protective role of RJ.
