Induction of hyperlipemia by carbohydrate-rich fractions isolated from crude papain.
A hyperlipemia was obtained in rabbits injected intravenously with two carbohydrate-rich fractions isolated from crude papain dialyzate. The fractions have an approximative molecular weight of 15,000 and 5,000 daltons and contains 35% and 15% of sugars respectively. The hyperlipemia appears 20 hours after the injection and consists in a hypertriglyceridaemia as suggested by the enrichment of serum in very light lipoproteins of density about 1.006. Concomittantly a decrease of the post-heparin lipase activity (PHLA) of the plasma was observed. After a few days the hyperlipemia disappears and the PHLA returns to a normal value. It is suggested that the hypertriglyceridaemia can be due to an inhibitory effect of the injected fractions on the removal action of the lipases which are released into the blood by an heparin injection.
