.../min/well. The uptake of both ascorbic acid and dehydroascorbic acid was dependent on the sodium concentration. The uptake of ascorbic acid does not involve oxidation-reaction steps because the uptake of [ 14 C]-ascorbate was unaffected by the presence of an excess amount of unlabelled dehydroascorbic...

...Péter Ràcz; Miklós Kellermayer Calcium, potassium and sodium concentration in normal and senile cataractous lenses was investigated in the course of a long-term dialysis. It was found that about 20% of the calcium content in normal lenses could not be dialysed, whereas in completely opaque lenses...

... variations in the values for ion and protein contents within any one group were observed. There was a good correlation between the increase in lens sodium and decrease in soluble protein and it is proposed that the Pirie classification scheme should be modified to allow for this cortical involvement. 3...
