【Abstract】 AIM: To study the cardiovascular effect of total soyabeans saponins (TS) in brain and its relation￣ship with monoamines. METHODS: After injection of TS (75 μg) into ventriculus lateralis cerebri (VLC) the changes of blood pressure (BP) and heart rate (HR) were observed and the contents of monoamines both in peripheral blood and brain (telencephalon, diencephalon, brain￣stem) were measured respectively by HPLC ECD and fluoro￣photometry. RESULTS: After injection of TS into VLC, BP rised from 11 59±0 84 to 14 59±0 69 kPa; HR increased from 411±21 to 465±14 bpm; the contents of NE and E in peripheral blood increased from 6±3 to 64±44, from 6±2 to 38±34 nmol/L plasma, respec￣tively, NE in brainstem increased from 14±0 to 18±3 nmol/g wet tissue respectively, but the contents of 5 HT in the 3 areas measured in the experiment decreased: in telecephalon from 9±1 to 5±1, in diencephalon from 14±2 to 7±2, in brainstem from 14±3 to 6±1 nmol/g wet tissue. CONCLU￣SIONS: The cardiovascular effects of TS in CNS were involved in the monoamine transmitters.更多还原
