[Driving phenomenon in neurons of the spinal center of frog lymph hearts].

Bioelectrical activity of motor axons of the lower lymphatic hearts was recorded in frogs. When the 5th and 6th dorsal roots were stimulated at a frequency lower than the spontaneous frequency, artificial bursts of motor impulses were usually produced together with spontaneous impulses. Latency of artificial impulses depended upon the time of stimulation in the interburst interval.

[Effect of 7 days of administration of prednisolone and methandrostenolone on the incorporation of glycine-1-c14 into liver, thymus and splenic proteins].

Daily injections of prednisolone (10 mg/kg) for a space of 7 days to albino male-rats cause an increased synthesis of nuclear and mitochondrial proteins without changing the protein synthesis of other liver fractions. Following injection of prednisolone the protein synthesis in the spleen went up and in the thymus remained unchanged. This was paralleled by stronger decay processes of the lymphoid organs.
