Effects of insulin on the uptake of D-galactose by isolated rat epididymal fat cells.

In muscle, insulin stimulates uptake of D-galactose as well as D-glucose and certain other sugar isomers (Kono, T. and Colowick, S.P.

Actions of insulin in fat cells. Effects of low temperature, uncouplers of oxidative phosphorylation, and respiratory inhibitors.

When isolated rat epididymal fat cells were incubated with [125I]iodoinsulin for 5 min at 37 degrees, radioactivity accumulated in the plasma membrane fraction (Peak 1) and an unidentified particulate fraction (Peak 2) as reported previously (Kono, T., Robinson, F.W.

Effect of PCO2 on epinephrine-induced lipolysis in isolated fat cells.

The effect of different pHs obtained by changing the PCO2 and the effect of PCO2 at constant pH on the lipolysis induced by epinephrine in isolated fat cells have been investigated. An inhibition of activated lipolysis was found in acidosis while in alkalosis no significant change was detected. When the experiments were performed at different PCO2s but at constant pH, the results showed an inhibition of lipolysis by high PCO2 whereas low PCO2 did not affect it.

Acute renal insufficiency in the rabbit by glycerol.

The appearance of an acute renal insufficiency in the rabbit, after glycerol injection (10, 13 or 15 ml/kg of a 50% solution) is investigated. After a 24 hours of intoxication, especially in the ten following days, cylinders, erythrocytes and renal cells appear in the urine sediment. Proteinuria appears after 24 hours and practically disappears after 72 h.
