[Study of zinc and copper serum levels in dislipemias].

The possible alterations of zinc and copper serum levels in dyslipemies were studied. The population were classified taking into account total cholesterol HDL and triglycerides levels and the serum test at 4 degrees C in 4 groups: 1) Hypercholesterolemia (type II A), 2) Endogenous hyperlipemia (types II B and IV), 3) Mixed hyperlipemia (type V), 4) Exogenous hyperlipemia (Type I), and also the presence of over weight ("15% ideal weight body, according to Bray), that occurred in the 29.5% of the sample.

[Changes in various hematologic parameters following treatment with zinc acetate].

The effect of different doses of zinc acetate (1,000 and 3,000 ppm) on several haematological values was studied on Wistar rats. Decreased haematocrit, mean corpuscular volume and white cell counts were appreciated, along with increased red cell counts. The leucocyte differential count was also modified, an important reduction of the percentage of neutrophils and monocytes being registered.

[Levels of Zn and Cu in the serum of a diabetic population].

The zinc and copper content in serum as well as glucose and insulin was determined in 140 diabetics and compared with the results obtained from 162 healthy patients. Their mean values are significantly different. Each group was classified accordingly to the presence or not of overweight (greater than 15% relative body weight).

[Pancreatic secretion in rats treated with intra-aortic prostaglandin E1].

The effects from one dose of PGE1 on the endocrine pancreatic secretions have been studied in rat. The dose is injected i.a.

[Effect of alloxan in pancreatectomized rats (author's transl)].

Sensitivty to alloxan of pancreatectomized rats is studied injecting on the seventh day after surgical resection with different dose of monohydrated alloxan. Totally pancreatectomized rats develop a strong diabetes just the same as the control group, but the former present higher glycemias and longer survival.
