[Objective] To compare the antipyretic and anti-inflammatory actions and acute toxicity between Chuanxinlian Soft Capsules (CSC) and Chuanxinlian Tablets. [Methods] Antipyretic action of CSC was observed on rabbit fever models induced by lipopolysaccharide (LPS) and rat fever models induced by baker's yeast. Rat models with pedal swelling induced by carrageenin, mouse models with auricle swelling induced by dimethylbenzene and mouse models with celiac capillary hyperpermeability induced by acetic acid were used to observe the anti-inflammatory action oi CSC. Its acute toxicity in mice was also evaluated. [Results] High- and moderate-dose CSC reduced fever in rabbits induced by LPS (P 0.05). High-, moderate- and low-dose CSC has an inhibitory effect on acute inflammatory exudation (P

The concentrations of borneol in the serum and brain tissue of rats were determined by gas chromatography. Using brain tissue as a relatively independent system, PHARMFIT and PCNONLIN softwares are applied for the kinetic analysis of the infracorporal process of borneol in order to find out and compare the pharmacokinetic characteristics of borneol in the brain and serum. The results showed that borneol was absorbed very rapidly in the gastrointestinal tract and readily permeates the blood-brain barrier into brain tissue. There was a higher specific value of borneol concentration in the brain and serum. Moreover, the half life of distribution phase of borneol in the brain was three times higher than that in the serum. But the constants of elimination rate of borneol in the brain and serum decreased simultaneously and parallelly, hence the accumulation of borneol in brain will not be found.
