Effects of denervation on the neuraminidase activity of slow and fast muscles of rabbits.
The presence in skeletal muscles of rabbits of neuraminidase activity on sialyl lactose was demonstrated. By comparing the specific activity of this enzyme in different control muscles, it was shown that it was 2.3 times higher in the slow than in the fast muscles. Seven days after denervation, we observed a significant increase of activity in fast muscle and a significant decrease of activity in slow muscle. These results, together with previous data, are in favour of the hypothesis that turnover of muscle glycoconjugates is under a type-specific neural control.
