The effect of selected membrane active substances on erythrocyte deformability.

Aminoguanidine improved the erythrocyte filterability by 4%, pyridoxyliden-aminoguanidine by 11% and pyridoxal by 13% in healthy subjects. In diabetic patients the aminoguanidine effect on erythrocyte filterability was improved by 7%, PAG effect by 9% and pyridoxal effect by 15% in comparison to the control group. The other investigated haematological variables in both groups were within the range of the physiological standard. All of the tested substances demonstrated a mild protective influence on erythrocyte elasticity both in healthy subjects and diabetic patients. Significant elasticity improvement was obtained only by pyridoxal (p<0.01) in patients with diabetes mellitus. (Fig. 4, Ref. 18.).
