RESUMO
The absolute number of T4 cells and the serum concentrations of Ca, Cu, Fe, K, Mg, P, Se, and Zn were determined in 59 Walter-Reed staged, HIV-infected men, compared to healthy controls, serum levels of Ca, Cu, and Fe were significantly higher, those of P and Se significantly lower in the HIV-infected subjects. In the HIV-infected cases, but not in the controls, the concentrations of Se and Zn, of Ca with Cu and Fe, and of Fe with P, were directly correlated. In the controls, the correlation between the levels of K and Mg was direct, and inverse between those of Zn and P. Trace element levels did not significantly correlate with WR-stage. However, the absolute number of T4 cells was directly correlated with the serum Mg concentration.

The absolute number of T4-lymphocytes was directly correlated with the serum Mg concentration.

The dilution in the circulating blood of lymphocytes lablled in vitro with 3H-cytidine was examined after autotransfusion in 9 patients with Hodgkin's disease (HD) stage II A-IV B, 5 of whom were untreated; in 2 untreated patients with carcinoma, and in 1 treated patient with scleroderma. The blood transit time of exchangeable lymphocytes was 37 +/- 18 min in the patients with HD and 26 +/- 6 min in the other patients. The proportion of exchangeable (recirculating) small blood lymphocytes was 39-84% in HD and 81-91% in the carcinoma patients. The relation between the size of the circulating pool of small blood lymphocytes and the total exchangeable (recirculating) lymphocyte pool was 1:20 to 1:30 in HD and 1:29 to 1:34 in the other patients. The absolute size of the recirculating pool of lymphocytes was 46-90 times 10(9) cells in HD and 100-150 times 10(9) cells in the carcinoma patients.
