Antihypertensive polar and neutral renopapillary lipids. Which is a hormone?

Antihypertensive Polar and Neutral Renopapillary Lipids

Two antihypertensive lipids can be derived from the renal papilla, the antihypertensive polar (APRL) and the antihypertensive neutral (ANRL) renomedullary lipid. The renal venous effluent of the undipped kidney contains both ANRL and APRL. This effluent lowers the arterial pressure (AP) of the normal rat when infused i.v. As it lowers the AP the heart rate (HR) and sympathetic nerve activity (S...

Cardiovascular effects of antihypertensive polar and neutral renomedullary lipids.

Two antihypertensive lipids can be extracted from fresh renal medulla. One is polar (the antihypertensive polar renomedullary lipid, or APRL) and the other is nonpolar (the antihypertensive neutral renomedullary lipid, or ANRL). APRL and ANRL differ in their biologic activities: APRL in bolus intravenous injections causes a very rapid decline in the arterial pressure (AP) while ANRL, after a la...

Is Nitric Oxide a Hormone?

Nitric oxide (NO) is a simple ubiquitous signaling molecule and plays important roles in almost every biological system. Recent evidences suggest that NO may act as an endocrine molecule. The aim of this review is considering available literature on endocrine roles of NO and/or its metabolites, i.e. nitrite and nitrate. Existing data suggest the idea that NO is a hormone that after production i...

Which is which and who is who: Roger Waters up against Media

Pink Floyd was a British band whose work began in the late 60s. Roger Waters, the main contributor of the band, wrote almost all the lyrics and was also a main figure behind producing the motion picture of the album. He deliberately attacks Western media in both the lyrics he has written for the band and his solo projects. The present study finds this tendency of assaulting the media deeply roo...
