Abstract: Objective Illuminate the method of using MS-302 analytical system to determine some physiological norms of the rats.Method 10 clean Wistar rats were used in this study.To determine the frequency of heart beat,the blood pressure of neck artery,the frequency of breath,the extent of breath muscle of the rats using MS-302 physical analytical system.Result The heart rate was 331～378 beat/min.The average blood pressure was 92.4～115.9mmHg,the average blood contract pressure was 101.7～129.3mmHg,the average blood loosen pressure was 92.4～115.9mmHg.The frequency of breath was 56～92 beat/min,the extent of breath muscle was 3.8～6.0g.Conclusion The MS-302 system provides a good reference foundation in determining some physiological norms of animals.

摘要： 清洁级Wistar大鼠颈总动脉插管,使用MS-302生物信息计算分析系统接驳计算机,皮下注射生理盐水(0.5mL/100g),比较分析注射前、注射后15ms、30ms、45ms、60ms、75ms、90ms之Wistar大鼠的心率、颈总动脉收缩压、平均压、舒张压、呼吸频率、呼吸张力的变化。结果显示:清洁级Wistar大鼠的心率为331~378次/min,颈总动脉平均血压为92.4~115.9mmHg,收缩压为101.7~129.3mmHg,舒张压为82~110.2mmHg;呼吸频率为56~92次/min,呼吸肌张力为3.8~6.0g。特别是Wistar大鼠呼吸肌张力指标的测定为应用提供了新的参考依据。
