OBJECTIVE: To observe the effects of the extracts from Herba Lagopsis (HLE) on lymph microcirculation of acute blood stasis rats. METHODS: The acute blood stasis model was made by iv dextran (10 ml/kg) within 1 min. After 6 minutes, HLE(1.0g/kg) was given intravenously to the treatment group and the same volume of NS was done in the normal control group. The changes of contractility of mesenteric micro-lymphatics (ML) was observed by using a vital microscope with TV recorder. RESULTS: HLE could markedly improve the ML spontaneous constraction frequency, lymphatics constractive activity (Index I), total lymphatics constractive activity (Index II) and lymphatics dynamics (L. D-Index) (P < 0.05 approximately 0.01). CONCLUSION: HLE played an important role in lymph microcirculation of acute blood stasis rats.
