Abstract:
Adult albino rats, weighing 140-380 grams, were chosen for study on the effects of starvation, anaesthesia and nervous stimulation on liver glyco- gen and ribonucleic acid. Tissues were fixed in cold Carnoy's fluid, embedded in paraffin, stained with McManus' PAS method for glycogen and with methyl green-pyronine method for ribonucleic acid. Glycogen decreased considerably after 5 to 6 hours starvation and disap- peared completely after 8 hours. Ribonucleic acid also showed signs of decomposition and became more diffusely distributed. Anaesthetic starvation after intraperitoneal injection of 1% sodium amytal had less effect than that of starvation. When sciatic nerves of old rats were stimulated with 0.7-0.9 volts inducted current for 4 to 6 hours, liver glycogen disappeared completely and the depletion of liver ribonucleic acid was more pronounced than that of starvation. With young rats of 2 to 3 months of age, the influence was indistinct.
