RESUMO
By using the fluorescent, DNA specific stain DAPI (4',6-diamidino-2-phenylindole) some microscopic observations of Candida albicans pseudomycelium and chlamydoconidia were performed. In this manner blue fluorescent dots were noted both in yeasts, psudomycelium and chlamydoconidia, so evidencing the presence of a nucleus in C. albicans chlamydoconidia.

Platelet count and platelet function (circulating platelet aggregates, retention by glass beads and aggregation) were studied under basal conditions and after a cycloergometric exercise test in 10 subjects with stable angina pectoris and 10 normal subjects. There were no baseline differences between patients and controls in any of the tests of platelet function, nor did the values change after the exercise test. There was, however, a significant increase in the number of circulating platelets after the test in angina patients. Possible reasons for this phenomenon are discussed, with emphasis on the role of catecholamine hypersecretion induced by the physical exercise.

Serum total lipids, lipoprotein cholesterol, apolipoprotein A (Apo A), and liver function tests have been investigated in patients with acute viral hepatitis and chronic liver disease. Hypertriglyceridaemia, absence of alpha and pre beta bands on the lipoprotein electrophoresis pattern, low level of Apo A, and presence of abnormal lipoproteins (beta-VLDL and beta2-LP) were observed in the early phase of acute hepatitis. A positive correlation was found between Apo A and high-density lipoprotein cholesterol, and a negative one between Apo A and triglyceride, bile acids, total bilirubin, and serum alanine aminotransferase. Lipoprotein abnormalities found in the early phase of acute hepatitis are probably due to low lecithin-cholesterol acyltransferase activity. The reappearance of alpha lipoprotein and the increase of Apo A are sensitive indices of improvement of liver function. In chronic liver disease low levels of cholesterol and Apo A indicate the severity of liver cell injury.
