"[Researchers] values obtained beyond 50µm from
the endplate, range, on the average, from ~100 sites/µm^2
for 3-d denervates to ~200 sites/µm^2 10 d after denervation.
These values are consistent with those given by different
techniques in studies using rodent extensor digitorium
longus, soleus, or sternomastoid muscles (Pestronk et al.,
1976 Change et al., 1975 Levitt-Gilmour and Salpeter,
1986 Loring and Salpeter, 1978). These above mentioned
studies report 150-180 sites/µm^2 4-5 d after denervation,and 200-370 sites/µm^2 7 and 8 d after denervation. Higher
values (~500 sites/µm^2) given by Fambrough (1974) for rat
diaphragm 14 d after denervation may reflect differences in
technique or a continued rise in site density with time after
denervation." |
