2. Pharmacological action
1, hypotensive: Pu Tao has hypotensive effect on anesthetized rats, rabbits, cats and dogs, as well as renal hypertensive rats and dogs. Water immersion and decoction are the strongest, followed by fluid extract, and ethanol, ether and chloroform extracts are ineffective. Muscle, vein and oral administration can lower blood pressure. Hot dip and its extract (precipitate obtained by adding calcium chloride after alkalization of hot dip) showed twice antihypertensive effect after intravenous injection in dogs. The first action is strong and short-lived, which appears immediately after injection and recovers in 30-60 minutes. The second effect is mild and lasting. Intramuscular injection and oral administration can only cause a second antihypertensive effect, which can last for 2-3 hours. Intravenous injection of decoction only has the first-order antihypertensive effect, but oral administration is ineffective. The first antihypertensive effect is probably not unique to Haizhou Changshan, and it seems to have no practical significance in treatment. The antihypertensive effect of leaves collected before flowering in Changshan, Haizhou is better than that collected after flowering. When fruit sets, the old leaves harvested every other year have little effect on lowering blood pressure. Heating for too long will also reduce the effect. If it is compatible with earthworm, it has synergistic effect on lowering blood pressure.
As for the hypotensive principle of this product, it is preliminarily considered that it is mainly caused by directly dilating blood vessels, and the blockade of ganglion also has some influence. Some people think that it is mainly through the central (cross circulation and Plutarch block test) to stimulate intravascular receptors to lower blood pressure and reduce the excitability of vascular motor centers. Others believe that all the above factors are at work. A more comprehensive point of view is that the primary hypotensive effect is closely related to direct vasodilation and blocking autonomic ganglia, and may be involved in reflex. The second hypotensive effect is probably caused by the central nervous system above the spinal cord dilating some visceral vessels, which is related to some internal receptors.
