The ANRL was derived from the renal venous effluent as the kidney exerted its nonexcretory antihypertensive function. This was made possible by three developments: (1) improvement in the extraction of ANRL from fresh renal medulla; (2) the fact that purified ANRL caused an acute vasodepressor effect (acted as a vasodilator); and (3) experience with unclipping the one-kidney, one-clip hypertensive rat. Unclipping after an anastomosis between the
ureter
and the vena cava caused the
MAP
to return to normal levels in an average of 20 hr. At an average of 5 hr, when the
MAP
had dropped an average of 34 mm Hg (from approximately 190), an exchange infusion was started and blood was collected from the renal vein. The plasma was separated, lyophilized, and extracted for total lipids. The lipids were subjected to two TLC procedures and tested for vasodepressor activity. Renal venous effluent, under those conditions, yielded a considerable amount of vasodepressor lipid that was similar to that derived from fresh renal medulla. Controls (normal, nephrectomized, and hypertensive animals) yielded little or no such lipid. Indomethacin did not interfere with the derivation of the vasodepressor lipid. As the
MAP
was lowered and the ANRL-like lipid appeared in the renal venous blood, the RICs degranulated. The RICs appear to be the source of the antihypertensive lipid.

Quantitative chemical analysis of 225 urinary calculi (128 Renal, 57 bladder and 40
ureter
) collected from hospitals of different districts of Haryana was carried out. CaOxM was found to be present as a major component in all the stones analysed, while
MAP
, HA, CA and UA were found in 83.7%, 83.6%, 13% and 78.9% cases, respectively. The content of CaOxM was found to be higher in renal stones as compared to
ureter
and bladder stones, while the concentration of
MAP
was higher in bladder stones as compared to kidney and
ureter
stones. HA content was higher in
ureter
and UA was higher in bladder stones as compared to other urinary stones.
