Alpha-amylase inhibitor of amadumbe (Colocasia esculenta): Isolation, purification and selectivity toward α- amylases from various sources
Two proteins (A-1 and B-2) with a-amylase inhibitor activity were extracted and partially purified from Colocasia esculenta tubers through 80% ammonium sulphate fractionation, ion-exchange chromatography on DEAE-Sephacel and gel-chromatography on Sephadex G-100. The molecular weight of A-1 and B-2 were estimated to be about 17000 and 19000 daltons, respectively. The inhibitors inactivated a-amylases of...

Influence of sub-chronic oral exposure to high monosodium glutamate on some serum markers of the renal functions in male Wistar rats
Monosodium glutamate (MSG) is a flavor enhancing food additive that may be present in packaged food without appearing on the label. This could increase the possibility of its inadvertent consumption in high concentration. The study investigated the effects of MSG on some serum markers of renal functions in adult male Wistar rats by daily oral exposure to 3 ml kg-1 dose distilled water (DW) and 15 mg kg-1 MSG...

Adsorption, metabolism and degradation of erythromycin in giant freshwater prawn and tilapia aquaculture in Mekong River Delta
Adsorption, metabolism and degradation of erythromycin in freshwater prawn and tilapia aquaculture in Mekong River Delta were monitored and evaluated. They were fed practical diets medicated with erythromycin (50 and 100 mg. kg-1 body weight for 7 days). Erythromycin residues in their muscle were determined by the liquid chromatography - mass spectrometry/ mass spectrometry (LC-MS/MS) method. Our study provided...
