[Acute hydrothorax as a complication of peritoneal dialysis: report of a case and review of the literature].

Report a case of a patient suffering from acute pancreatitis with renal failure, who needed peritoneal dialysis and developed acute hydrothorax as a complication of the procedure. The diagnosis was made by the high levels of glucose on pleural effusion (455 mg/dL) and glycemia of 81 mg/dL). This complication probably occurs because of a pathological diaphragmatic defect, communicating peritoneal and pleural cavities.

Study of interactions between Listeria monocytogenes and experimental tumors.

Objective: to verify the effects of Listeria monocytogenes (LM) inoculation in the survival of animals bearing Ehrlich's tumor. KIND OF STUDY: experimental. Animals-isogenic mice, Balb/c, female, 19-21 g.

[Action of 3,5,3'-triiodothyronine (T3) on Walker's 256 carcinosarcoma development].

In order to verify the effects of triiodothyronine (T3) administration in animals bearing Walker tumor, the authors have carried out an experimental study utilizing Wistar rats inoculated with both ascitic and solid Walker tumor, and Balb/c isogenic mice for the study of spreading of macrophages. The animals were treated with T3 20 micrograms/100 g of body weight and the data were analysed by Chi-square and Mann-Whitney tests. The authors conclude that T3 increases significantly the survival of rats bearing Walker tumor, and the spreading of macrophages when inoculated into the peritoneal cavity of mice.

[Effects of H2 blockers on the spreading of macrophages in vitro].

Purpose: To verify if cimetidine, ranitidine, and famotidine, when inoculated by ip route in mice, do enhance macrophage activation and whether or not such activation is altered with prior use of sodium thioglycolate. KIND OF STUDY: Experimental.

Animals: isogenic, Balb/c mice, 19-21 g.
