Abstract
|
|
|
This study was carried out to investigate the effect of Heapyoyangjintang and Haepyoejintang extract on the contractile force of the isolated guinea pig trachea smooth muscle and elucidate its mechanism.
The results were obtained as follows :
1. The isolated trachea smooth muscle was suspended in the organ bath with oxygenated kreb’s Henseleit bicarbonate buffer solution at , and the developed tension by the drug was recorded with Isometric transducer(nacro F-60). The resting tension was approximately 0.5g.
2. The trachea smooth muscle of the isolated guinea pig was significantly relaxed by the administration of Haepyoyangjintang and Haepyoejintang extract.
3. The contractile response of the trachea smooth muscle of the isolated guinea pig to histamine Was significantly inhibited by Heapyoyangjintang and Haepyoejintang extract.
4. The contractile response of the trachea smooth muscle of the isolated guinea pig to acetylcholine was considerably inhibited by Haepyoyangjintang and Haepyoejintang extract.
5. The contractile response of the trachea smooth muscle of the isolated guinea pig to 5-hydorxytrtrypptamine was considerably inhibited by Haepyoyangjintang and haepyoejintang extract.
