Effect of cytogenin, a novel immunomodulator, on streptozotocin-induced diabetes in mice

ABSTRACT The anti-diabetic effect of cytogenin was examined using streptozotocin-induced diabetes in mice. Cytogenin suppressed not only the increase of plasma glucose level but also the


body weight reduction in diabetic mice. Histological examination of the pancreas taken from diabetic mice given cytogenin showed that cytogenin decreased the number of macrophages


infiltrated into islet of pancreas. Further, cytogenin suppressed the nitric oxide generation by macrophages treated with lipopolysaccharide through decreasing of inducible nitric oxide


synthase expression. Cytogenin suppressed interleukin-6 expression by macrophage treated with LPS, suggesting that the anti-diabetic activity of cytogenin might be partly attributed to the


suppressive activity against nitric oxide generation. SIMILAR CONTENT BEING VIEWED BY OTHERS COMPARATIVE IMPACT OF STREPTOZOTOCIN ON ALTERING NORMAL GLUCOSE HOMEOSTASIS IN DIABETIC RATS
