Urinary N-Acytyl β-D glucoseaminidase EC: 3.2.1.31 is a lysosomal enzyme which is classified in hexosaminidases group. This enzyme is found in different tissues such as, kidney, liver and spleen, but the kidney has maximum level of enzyme.The first step was the standardization of colourimetry and flourimetry of enzyme assay. In colourimerty method para-nitrophenyl N-acetyl β-D-glucosamine is used as substrate and in flourimetry method the subst...

The renin-angiotensin system (RAS) has been implicated in the development of diabetic vascular complications and angiotensin converting enzyme (ACE) has a major role in this system. This study sought to examine the in vivo effect of aqueous extract of garlic (Allium sativum) on the level of ACE activity of serum from streptozotocin (STZ)-diabetic and non-diabetic rats. Serum ACE activity measured by Cushman and Cheung colorimetric assay in the beginning of diabetes indu...
