1935年 Von Euler 在研究人精液和绵羊精囊提取物时,首先发现一类可溶性酸性脂类,后者在体外能使非血管平滑肌收缩,静脉注射后使动脉压降低。设想这类物质可能由前列腺分泌而来,故命名为前列腺素(简称 PG)。以后发现其并非由前列腺分泌,而是来源于精囊。尽管目前已知 PG 可产生于所有组织、器官和细胞,但仍保留该名称。 In 1935, when Von Euler studied human semen and sheep seminal vesicle extract, first discovered a class of soluble acidic lipids, which in vitro can make non-vascular smooth muscle contraction, arterial pressure after intravenous injection to reduce. Imagine such substances may be secreted by the prostate, it is named prostaglandin (referred to as PG). Later found that it is not secreted by the prostate, but from the seminal vesicle. Although it is currently known that PG can be produced in all tissues, organs and cells, the name is retained.
