Abstract:
This study aimed to develop a simple microfluidic chip analysis technology to study the inhibitory effect of protocatechuic acid on shear-induced platelet aggregation. The microfluidic chip designed in this study simulates 80% fixed narrow microchannels. This microchannel narrow model uses the finite element analysis module of the three-dimensional modeling software solidwork to analyze fluid dynamic behavior. Blood treated with protocatechuic acid at 1, 2, 4, 8, or 16 µg/mL was passed through the microchannel stenosis model at a shear rate of 10,000 s−1. The platelet adhesion and aggregation

Background. Present study was designed to evaluate the protective effects of protocatechuic acid alone and in combination with ascorbic acid in aniline hydrochloride induced spleen toxicity in rats.Materials and Methods. Male Wistar rats of either sex (200–250 g) were used and divided into different groups. Spleen toxicity was induced by aniline hydrochloride (100 ppm) in drinking water for a period of 28 days. Treatment group received protocatechuic acid (40 mg/kg/day, p.o.), ascorbic acid (40 mg/kg/day, p.o.), and combination of protocatechuic acid (20 mg/kg/day, p.o.) and ascorbic acid (20

Abstract:
UDP-glucuronosyltransferases (UGTs) are important detoxification and drug-metabolizing enzymes, which catalyse the glucuronidation of exogenous and endogenous chemicals. The anti-carcinogenic activity of dietary phytochemicals is partly attributed to the induction of phase II enzymes, including UGT1A. Our earlier study showed that protocatechuic acid increased UGT activity in rat liver. A similar effect was observed for indole-3-carbinol and phenethyl isothiocyanate in rat liver.
