the effects of treatment with dl , d- or l-propranolol ( subcutaneously for 1 week ) on arterial blood pressure and on 6-keto prostaglandin ( pg ) f1 alpha ( stable metabolite of pgi2 ) and pge2 production by aorta , renal medulla and renal cortex were examined in spontaneously hypertensive rats . dl-propranolol and l-propranolol significantly ( p less than .05 ) lowered blood pressures from 148 +/- 9/113 +/- 5 ( n = 6 ) and 133 +/- 4/100 +/- 2 ( n = 12 ) mm hg to 112 +/- 3/80 +/- 3 and 121 +/- 3/81 +/- 3 mm hg , respectively .
