β¦ Synopsis
The binding of acetazolamide to human erythrocytes was studied in vitro. Blood and plasma samples were analyzed by electron-capture GLC. At 37 degrees, drug equilibrated between plasma and erythrocytes in approximately 40 min. The effect of plasma concentration on the steady-state level of drug within the erythrocytes was examined. Erythrocyte accumulation of acetazolamide appeared to be a composite of two processes: a nonlinear, saturable process and a linear, diffusion-controlled process. By appropriate linear transformation of the data, estimates of the data, estimates of the erythrocyte binding capacity and the dissociation constant for the drug were obtained.

## Abstract The erythrocyte is a cell highly exposed to oxygen pressure that, in turn, provokes oxidative stress involving loss of SHβgroups, cell shrinkage by activation of K^+^βCl^β^ cotransport (KCC) and membrane destabilization which plays an important role in the premature haemolysis of red bl

Myoinositol uptake by rat hepatocytes in vitro was studied. Adult rat hepatocytes were prepared by digestion of the perfused liver with collagenase. Cell suspensions were incubated with tritium-labeled myoinositol in pH 7.4 Krebs bicarbonate solution containing 1% gelatin at 37 degrees. 14C-Carbon-l
