: Melatonin and Roentgen Irradiation of the Testes. .
Melatonin is a free-radical scavenger and antioxidant. Roentgen irradiation of testis (animal model formed of albino rats) was associated with destruction and depletion of the germinal epithelial cells. In roentgen-irradiated, melatonin-pretreated animals, these changes were markedly ameliorated. Thus administration of melatonin before irradiation can protect testis from some of the destructive effects of roentgen irradiation. Read more

Morphological Evaluation of the Radio protective Effects of Melatonin Against X-Ray Induced Early and Acute Testes Damage in Albino Rat: an Animal Model
Irradiation has profound effects on the reproductive function. Our knowledge about radioprotective effects of melatonin against X-ray-induced testis damage is rudimentary. In this investigation, we hypothesized that melatonin can minimize germ-cell depletion and morphological features of cell damage in testis following X-ray irradiation (XRI). To examine these effects, and to test our hypothesis, an animal model comprised of 60 Albino ... Read more

Ultra structural Evaluation of the Radio protective Effects of Melatonin Against X-Ray Induced Skin Damage in Male Albino Rats
Our knowledge about the radioprotective effects of melatonin against X-ray-induced skin damage is still lacking. To examine these effects, an animal model of 60 Albino rats was used. The animals were divided into five groups: Group 1, nonirradiated; Group 2, X-ray irradiated (XRI, 8 Gy); Group 3, XRI pretreated with solvent (ethanol and phosphate-buffered saline); Group 4, nonirradiated group treated ...

Melatonin enhances the toxicity of radio-and chemotherapy in head and neck cancer cells
After reported a melatonin’s gel that protects normal cells from oral mucositis induced by radio- or chemotherapy, we wondered about how melatonin affects tumoral cells. It is well known that both radio- and chemotherapy act at different intracellular levels such as nucleus, membranes and mitochondria. On the other hand, mitochondrion is the main melatonin target. So we evaluated here whether ... Read more
