在２８只兔体上用二道生理记录仪分别记录了三种麦饭石（Ｎ０１、Ｎ０２、Ｎ０３）对动脉血压（ＢＰ）、心率（ＨＲ）、心电图（ＥＣＧ）和呼吸频率（ＲＲ）的影响。结果表明，静脉点滴麦饭石浸泡液后，三组动物的ＢＰ和ＨＲ均有所降低，但只有Ｎ０１组改变显著，１２ｍｉｎ时其ＢＰ从对照９．２±１．３～１３．５±１．２ｋＰａ降至６．１±３．５～１０．１±４．０ｋＰａ（Ｐ＜０．０５），同时ＨＲ从３１０．０±３３．５降至２７３．３±２７．８次／分（Ｐ＜０．０１）。三种麦饭石对ＲＲ和ＦＣＧ无明显影响。
Two physiologic recorders were used to record the blood pressure (BP), heart rate (HR), electrocardiogram (ECG), and respiratory rate (RR) of three maifanites (N01, N02, and N03) on 28 rabbits. influences. The results showed that the BP and HR of the three groups of animals decreased after intravenous drip of Maifan stone soaking solution, but only the N01 group changed significantly. At 12 min, the BP from the control was 9.2±1.3 to 13.5±1. .2kPa was reduced to 6.1±3.5 to 10.1±4.0 kPa (P<0.05), while HR was decreased from 310.0±33.5 to 273.3±27.8/min ( P<0.01). Three types of Maifanite had no significant effect on RR and FCG.
