1. Pigs were maintained in air or in an atmosphere of nitrous oxide which dramatically changes the S-adenosyl-L-methionine to S-adenosyl-L-homocysteine ratio in neural tissues. Samples of cerebrospinal fluid, cortex, cerebellum and spinal cord were then extracted and analysed for S-adenosyl-L-methionine and S-adenosyl-L-homocysteine. Regression analyses were carried out on values obtained in cerebrospinal fluid and in neural tissues. 2. Highly significant correlations were obtained between… CONTINUE READING
