We present an epidemiologic study of the cases of cleft lip and cleft palate in Mississippi from 1980 through 1989. Cases were stratified by race (white and nonwhite) but not by association with a major malformation. During this period, a total of 457 new patients with cleft lip or cleft palate were identified from a population of approximately 439,354 live(More)
The ultimate goal in microvascular surgery is to achieve improved patency rates while reducing complications of systemic antithrombotic agents. Using a described model of microarterial thrombosis, the antithrombotic effects of oral aspirin (ASA) were assessed in rats. ASA-treated animals (30 mg/kg orally) exhibited significantly prolonged mean bleeding(More)
SUMMARY Bound gamma globulin was demonstrated by the direct immunofluorescent technique in heart tissue from three patients with severe congestive cardiomyopathy. In two of these patients complement (,81C) was also bound to the heart muscle. Heart tissue from one of six patients who died of myocardial infarction showed a trace of bound gamma globulin, but(More)
Benzidine and its 3,3'-diamino, 3,3'-dimethyl, 3,3'-dimethoxy, 3,3'-difluoro, 3,3'-dichloro, 3,3'-dibromo, 3,3'-dicarbomethoxy and 3,3'-dinitro derivatives together with 2-nitrobenzidine and 3-nitrobenzidine were compared for their in vitro and in vivo genotoxicity. Relative mutagenicity was established with Salmonella strains TA98, TA98/1,8-DNP6 and TA100(More)
C ardiomyopathy is a disease of unknown etiology in which presenting signs and symptoms result predominantly from dysfunction of the myocardium. A number of factors have been implicated in the causation of cardiomyopathy including alcohol,’ nutritional deficiency,2 the postpartal state,3 and virus infections.4*5 Among these considerations is an underlying(More)
Previous studies have suggested that successful transplantation of skeletal muscle to replace previously lost function depends on the mass of the transplanted tissue. In the present experiment, the possibility that careful microneurovascular surgical technique substantially improves the chances of successful transplantation of large-sized muscle was tested(More)
Ketorolac tromethamine (Toradol), a potent nonsteroidal anti-inflammatory drug used for postoperative pain, also strongly inhibits platelet aggregation. The anti-thrombotic effects of intramuscular ketorolac were assessed with a described rat model of microarterial thrombosis. After a single dose of ketorolac mean bleeding times were significantly prolonged(More)
Benzidine and 12 related aromatic amines have been studied for the effects of substituent groups and pi orbital conjugation on their genotoxicity as measured by their mutagenicity in vitro with Salmonella and by chromosomal aberrations (CA) in vivo in the bone-marrow cells of mice. The in vitro studies indicated increases in mutagenicity with increases in(More)
