1.Comparative effects of nitroglycerin and nicorandil on conroary circulation in ischemic region in dogs
Chinese Pharmacological Bulletin 1986;0(06):-
To comparet the role of nitrogly-cerin with nicorandil in relieving myocardial ischemia, a critical stenosis of the left anterior descending coronary artery was produced by an ex-ternal micrometer constrictor in 18 open chest dogs. Intracoronary infusion of nitroglycerin ( 1 ?g ? kg-1 ? min-1) had two effects: decreasing large coronary artery resistance (RL) and small coronary artery resistance (Rs) and increasing coronary blood flow (CBF) in first 5 min so as to relieve myocardial ischemia; then increasing RL, decreasing CBF and increasing whole blood viscosity (?o) and hematocrit (Hct) in coronary vein after 10 min so as to worsen myocardia ischemia. However, intracoronary infusion ofnicorandil(l ?g ? kg-1 ? min-1) increased CBF and decreased Rs and reduced ?o and Hct in coronary vein. The vasodilatory effect of nico-randil was moderate but long-lasting and it improved blood supply to the ischemic region in coronary circulation.

Objective To study the effects of measures for preventing early postburn damage in improving survival rate of burn patients during the third stage. Methods 12 568 burn cases admitted to our institute were chronically divided into three groups (1958-1980;1981-1990;1991-2000). Total burn surface area (TBSA), survival rate, incidence of burn shock, systemic infection and organ damage as well as the main treatments adopted in the recent decade were retrospectively analyzed. Results Incidence of burn shock, systemic infection and organ damage were significantly lower, and the total survival rate and the survival rate in patients with different TBSA were markedly higher in the third group as compared with those in the first and the second group. Incidence of organ damage in patients treated with delayed fast fluid infusion, early escharectomy en masse, early enteral feeding, early prevention of inhalation injury and gut bacterial translocation were also significantly lower than in the control. Conclusion Measures taken in the third group for preventing early postburn damage play an important role in improving the survival rate of burn patients.
