• 中文摘要： The pharmacological properties of the aque-ous extract of Cordyline terminalis kunth var.ti-bak Ball. were investigated in this paper.The results obtained are summarized as follows:1. Single dose of the extra t can not protect rats from the induction of stress ulcer.2. The extract reduces blood pressure of animal significantly both in acute and chronic treat- ment.3. In perfusion experiments, the extract con- stricts the hindleg vessels of frog in some cases occasionally, but dilates the vessels of the ear, lung, intestine and kidney of rabbit.4. In the isolated heart of frogs, rabbits and guinea-pigs, the extract induces a stimulant action in small doses but an inhibitory one in larger doses. The coronary outflow of the rabbit's heart shows a decrease in larger doses.5. The isolated smooth muscle of the rabbit's intestine and the rat's uterus is inhibited in all doses level.6. The extract has a direct paralytic action on the isolated rat phrenic nerve-diaphragm preparations.7. In mice, the extract causes a rapid death, probably due to respiratory paralysis, in- traperitoneally.
