title: [Relation between vitamin A and the fragility of red blood cells subjected to continuous mechanical trauma].
abstract: Is well-known the haemolitic action that A-vitamine exerts on the erythrocytes. With our study we have submitted the erythrocytes, of forty normal subjects, to incubation to 37 degrees C and to constant traumatic action with and without A-vitamine. After we have dosed the haemoglobin and potassium in the plasma to various times of incubation and traumatic action. The results demonstrate that this vitamine determines an increase of the fragility of the erythrocytes beyond the 100% after 120 minutes, while protects the membrane of erythrocytes to the release of potassium.
