Indomethacin or aprotinin infusion: effect on reversal of chronic two-kidney, one-clip hypertension in the conscious rat. 1982

G I Russell, and R F Bing, and J D Swales, and H Thurston

1. Blood pressure was monitored continuously in conscious rats with chronic Goldblatt two-kidney, one-clip hypertension. 2. Hypertension was rapidly reversed by removal of the constricting clip and the reversal was complete by 12 h, although structural vascular changes persisted for much longer. 3. Blood pressure in this model of hypertension was not affected by a 15 h infusion of either indomethacin or aprotinin. 4. The pattern of fall in blood pressure after removal of the clip was similar when animals were infused with either indomethacin or aprotinin. Blood pressure at 24 h was normal and did not differ significantly from that of unclipped rats given a glucose infusion. 5. The fall in blood pressure produced by unclipping therefore did not appear to be mediated via the prostaglandin or kallikrein systems.

D007213 Indomethacin A non-steroidal anti-inflammatory agent (NSAID) that inhibits CYCLOOXYGENASE, which is necessary for the formation of PROSTAGLANDINS and other AUTACOIDS. It also inhibits the motility of POLYMORPHONUCLEAR LEUKOCYTES. Amuno,Indocid,Indocin,Indomet 140,Indometacin,Indomethacin Hydrochloride,Metindol,Osmosin
D007611 Aprotinin A single-chain polypeptide derived from bovine tissues consisting of 58 amino-acid residues. It is an inhibitor of proteolytic enzymes including CHYMOTRYPSIN; KALLIKREIN; PLASMIN; and TRYPSIN. It is used in the treatment of HEMORRHAGE associated with raised plasma concentrations of plasmin. It is also used to reduce blood loss and transfusion requirements in patients at high risk of major blood loss during and following open heart surgery with EXTRACORPOREAL CIRCULATION.
