To explore the mechanism of Suanzaoren Decoction in the treatment of insomnia from endogenous bile acid regulation, the present study investigated the hepatoprotective effect of Suanzaoren Decoction and the molecular changes of bile acids in the serum, liver, and ileum of insomnia model mice and Suanzaoren Decoction treated mice. The insomnia model in mice was established by the sleep deprivation method. After Suanzaoren Decoction(48.

Objective: To reveal the effect and mechanism of Jiaotai Pill (, JTP) on insomniac rats.

Methods: The insomniac model was established by intraperitoneal injection of p-chlorophenylalanine (PCPA). In behavioral experiments, rats were divided into control, insomniac model, JTP [3.

Article Synopsis
  • The study investigated how Ploygoni Multiflori Caulis affects bilirubin transporters in both normal and idiosyncratic liver injury rat models (LPS).
  • After administering the herbal powder and extracts for 7 days, pharmacokinetic parameters showed significant changes indicating altered transporter activity, particularly for Oatp1a1, Oatp1b2, and MRP2.
  • Results suggest that Ploygoni Multiflori Caulis inhibits these transporters, leading to potential hepatotoxic effects observed through decreased AST and ALT levels in the rats.

To predict the mechanism of liver injury induced by Genkwa Flos, we investigated the effect of chloroform extract on UGTs and UGT1A1 activities of the liver microsomes in rat and human. In the present study, 4-nitrophenol(4-NP) and β-estradiol were elected as substrates to determine activities of UGTs and UGT1A1 by UV and HPLC. The results showed that there were 1.

Background: Rotigotine is a potent and selective D1, D2, and D3 dopaminergic receptor agonist. Due to an extensive first-pass effect, it has a very low oral bioavailability (approximately 0.5% in rats).

Objective: To prepare ligustrazine (TMPZ) ocular sustained-release implant, and investigate its in vitro drug release, pharmacokinetics in rabbit vitreum and in vitro correlation.

Method: Ligustrazine ocular sustained-release implants were prepared by micro-twin conical screw mixers with hot-melting extrusion method, with polyactic-co-glycolic acid (PLGA) as the matrix. HPLC was adopted to determine the concentration in vitreum after ligustrazine was implanted in rabbit eyes, in order to examine its in vivo sustained-release behavior, and study the correlation between in vitro and in vivo.
