The impact of busulfan on the testicular structure in prepubertal rats: A histological, ultrastructural and immunohistochemical study.

Busulfan is a widely used cancer chemotherapeutic agent. Temporary or permanent sterility in male patients is one of the most common side effects of this drug. The present study was performed to evaluate the changes in the microscopic structure of the testes of prepubertal rats, as well as the changes in PCNA and caspase-3 immune expression, at different durations after busulfan administration.

The possible protective role of melatonin versus garlic on monosodium Glutamate-induced changes in rat cerebellar cortex: histological, immunohistochemical and electron microscope study.

Monosodium glutamate (MSG) is widely used as a flavor enhancer. Melatonin and garlic are well known as antioxidant. The present study was performed to evaluate the microscopic changes in the cerebellar cortex of rats after the administration of MSG and the possible protective effect of melatonin versus garlic on those changes.
