title: A preliminary study of the levels of testis oxidative stress parameters after MK-801-induced experimental psychosis model: protective effects of CAPE.
abstract: We evaluated the effects of caffeic acid phenethyl ester (CAPE) on antioxidant enzyme levels and histopathologic changes in dizocilpine (MK-801) induced schizophrenic rat testis. A total of 30 adult male Wistar-Albino rats were divided into three groups. Group-I was used as control. Rats in the Group-II were intraperitoneally injected with MK-801, whereas those in Group-III were intraperitoneally injected with CAPE in addition to MK-801. The testes were collected for biochemical and histopathological examinations. Antioxidant enzyme activities, malondialdehyde, protein carbonyl and nitric oxide levels in testicular tissues were analyzed with spectrophotometric methods. Induction of schizophrenia resulted in a significant oxidative stress by increasing the levels of antioxidant enzymes. Tissue malondialdehyde and protein carbonyl levels were also increased. Treatment with CAPE led to significant decrease in oxidative injury. Administration of CAPE reduced the detrimental histopathologic changes caused by MK-801. The results showed that experimentally induced schizophrenia caused oxidative stress in testes of rats and treatment with CAPE reduced these harmful effects.
