catha/抗氧化剂

OBJECTIVE Khat (Catha edulis Forsk) is a naturally occurring drug with an amphetamine-like structure and action. It has been postulated that amphetamine induces free radical formation. On this basis, we have hypothesized that Khat may promote synthesis of reactive oxygen and nitrogen species in the

Khat chewing is widely practiced in Eastern Africa and the Middle East. Khat is genotoxic to cells within the oral mucosa, and several studies have suggested an association between khat use and oral lesions like hyperkeratosis and oral cancer. This study investigated the mechanism of khat-induced

BACKGROUND Although various studies have been conducted to shed light on the pharmacological actions of khat, little or no data are available regarding khat's effect on the renal redox system. The aim of this study was therefore to investigate the potential of nephrotoxicity associated with khat

BACKGROUND Cathinone hydrochloride is an active principle of the khat plant (Catha edulis) that produces pleasurable and stimulating effects in khat chewers. To the best of our knowledge no data of cathinone on oxidative stress in limbic areas of mice is available. This is the first study of

The effect of regular khat (Catha edulis) chewing and the combination of khat chewing and smoking on plasma lipid peroxidation as a biomarker of oxidative stress and free radical activity (measured as plasma malondialdehyde, MDA), as well as on the lipid profiles were investigated. The fasting
