title: Therapeutic associated with occupational exposure to silica.
abstract: Occupational exposure to silica dust has been increasing the possible risk of varieties of pathologies. The aim of this study was to evaluate the protective activity of ethanolic extract of Glycyrrhiza glabra roots at doses of 500 and 1000 mg/kg, p.o., given for 7 days against the toxicity of SiO(2) nanoparticles (50mg/kg intraperitoneal for 6 weeks) in rats. Exposure to silica altered various respiratory and biochemical variables, including ALT, AST, albumin, urea, uric acid, creatinine, catalase, LPO and GSH. Treatments with G. glabra extract significantly improved antioxidant status towards control. Stone workers in the Gwalior region exposed to silica dust had higher prevalence of cough, wheezing and shortness of breath. Increased serum ACE level was noted in the silica exposed group. It is of immense need to monitor this problem for betterment of worker's health.
