Question

non diffusible costituent present in blood​

Answer 1

Answer:

The transformation of the Folin-Wu method for the preparation

of protein-free blood filtrates into a method giving protein-free

extracts from unlaked blood (1) involves experimentally only the

simplest sort of modification, but produces results of far reaching

consequences. There will be necessarily a sharp break between

the hospital records or the past published records of blood analyses

based on aqueous extracts from laked whole blood and corresponding records obtained from unlaked blood. But the conclusion

seems inescapable that for nearly every kind of metabolism study,

it must be obscuring and misleading to include in the analyses of

blood as a transportation system, an unknown mixture of residues

obtained from the destroyed cellular elements which have no direct connection with the circulating waste products or food

products.

The disadvantage arising from a loss of continuity between past

records and new ones made on unlaked blood should be partly

compensated for by the fact that in the future there should be less

need for revisions of methods.
