Following an episode of rheumatic carditis, severe mitral incompetence developed in a 9-year-old girl. A mitral annuloplasty succeeded for a short time in ameliorating her symptoms of cardiac failure. However, mitral incompetence recurred and was accompanied by severe anemia and hemosiderinuria. Distortion of erythrocytes was evident on a peripheral blood smear. A second mitral annuloplasty resulted in resolution of the hemolytic anemia. 相似文献

The behaviour of the aerobic skin flora of the flexor sides of the forearms, under a three-week restriction of washing, was investigated in twenty-four patients for its quantitative and qualitative aspects. The combined scrabbing-washing method was used as described by Burtenshaw with Ringer's solution. After a three-week restriction of washing, using the Wilcoxon-Test, statistically no significant changes in the total number of microorganisms were found in areas investigated in the intermittent sampling of the skin flora. A three-week restriction of washing in the region of the flexor sides of the forearms does not induce significant changes in the composition of the normal aerobic skin flora. The percentage of differences in the total number of bacteria fluctuates up to the mark in wide limits; statements about standard deviations are not permitted because of the technical and experimental conditions. There was no shifting of the Resident flora to other groups of bacteria in the patients under study. Pathogenic microorganisms could not be found in higher numbers after the second sampling. 相似文献

The mass spectra of peracetylated daunorubicin, N-octanoyl-, N-dodecanoyl- and N-(N'-dodecanoyl-glycyl)daunorubicin, and perdeuteroacetylated N-dodecanoyldaunorubicin were analyzed. Major fragmentation pathways were suggested and ion compositions were determined by high resolution measurements. 相似文献

The use of isoniazid (INH) in persons exposed to active cases of tuberculosis has been challenged, Reports of toxic reactions to isoniazid warrant a review of the drug's potential benefits and hazards. This prompted a retrospective survey of cases admitted to a large county hospital to determine admission incidence before and since initiation of a program of case-finding and INH chemoprophylaxis for children in 1953. During the 24-year period surveyed (1950-1973), the population of the county increased twofold while the yearly admission rate for tuberculous meningitis in children fell from a high of eight cases to a low of two. This dramatic drop in cases admitted, coupled with an absence of any toxic reactions to the drug, provides support for continuation of the program of case-finding and isoniazid chemoprophylaxis. 相似文献
