Beneficial effects of valencene on altered glycoprotein components in streptozotocin-nicotinamide induced diabetic rats

Abstract

ABSTRACT
 Objective: To investigate the effect of valencene on dearrangement in glycoprotein levels in the streptozotocin(STZ)-nicotinamide(NA)induced diabetic rats. Materials and Methods: Diabetes was induced in experimental rats by a single intraperitoneal (i.p) injection of STZ (45 mg/kg b.w) dissolved in 0.1 M citrate buffer (pH 4.5) 15 minutes after the i.p injection of NA (110 mg/kg b.w). The levels of glycoproteins were altered in experimental diabetes mellitus. Valencene were administered to diabetic rats intragastrically at 100 & 200mg/kg bw for 30days. The effects of valencene on plasma glucose, insulin, plasma and tissue glycoproteins were studied. Results: Oral administration of valencene (200mg/kg b.w)for 30d, dose dependently improved the glycemic status in STZ-NA induced diabetic rats. The levels of plasma glucose were decreased with significant increase of plasma insulin level. The altered levels of plasma and tissue glycoprotein components were restored to near normal. Conclusions: The results of the present study show the potent beneficial effects of valencene in modifying the levels of glycoprotein components in plasma and tissues of diabetic rats.
