二术茯苓散及组分对鸡离体盲肠张力的影响

为探讨中药二术茯苓散及其组分对鸡离体盲肠运动张力的影响,试验采用离体器官试验法，将鸡的盲肠置于盛有生理溶液的麦氏浴槽内，维持（41±0.5） ℃恒温，分别加入不同剂量的白术、苍术、茯苓及二术茯苓散合剂水煎液，以观察离体肠管运动张力的变化。结果表明，二术茯苓散合剂和其组分药白术、苍术、茯苓水煎液均能抑制肠管的运动，使鸡离体盲肠收缩张力和舒张张力降低，收缩振幅减小。各种水煎液随着浓度的增加其抑制肠管运动的作用加强。

Effects of Erzhu Fuling San and its Components on the Tension of Isolated Caecum in Chook

In order to investigate the effects of erzhu fuling san and its components on the tension of isolated caecum in chook, isolated intestine was adopted, the chook’s caecum was put in the magnus’ bath （maintained （41±0.5） ℃ constant temperature）, then the vary dosage decoction of rhizoma atractylodis, atractylodes macrocephala, tuckahoe and erzhu fuling san were added to observe the effect on the tension of isolated intestine. The result indicated that erzhu fuling san and its components (the decoction of atractylodes macrocephala, rhizoma atractylodis and tuckahoe) restrained the movement of intestine, reduced the contract and diastole tension and contract swing of chook’s isolated caecum.The effects of all kinds of the decoction enhanced with increase of the concentration.
