Active-phase Plasma Alkaline Phosphatase Isozyme Activity Is a Sensitive Biomarker for Excessive Fructose Intake.

Background/aim: Excessive fructose intake reportedly leads to the development of nonalcoholic fatty liver disease (NAFLD). In our previous study, we reported that plasma activities of alkaline phosphatase (ALP) isozymes were markedly changed in rats with excessive fructose intake-induced hepatomegaly. In this study, we examined ALP isozyme activity prior to the occurrence of hepatomegaly, and investigated the effect of the timing of sample collection, to explore its potential as a biomarker.

Estimation of potential risk of allyl alcohol induced liver injury in diabetic patients using type 2 diabetes spontaneously diabetic Torii-Lepr (SDT fatty) rats.

In order to estimate the potential risk of chemicals including drug in patients with type 2 diabetes mellitus (T2DM), we investigated allyl alcohol induced liver injury using SD rats and Spontaneously Diabetic Torii-Lepr (SDT fatty) rats as a model for human T2DM. The diabetic state is one of the risk factors for chemically induced liver injury because of lower levels of glutathione for detoxification by conjugation with chemicals and environmental pollutants and their reactive metabolites. Allyl alcohol is metabolized to a highly reactive unsaturated aldehyde, acrolein, which is detoxified by conjugation with glutathione.
