The sciatic nerve of the South African frog (Xellopus laevis) was totally constricted while the animal was under ether anaesthesia, and the animal was kept alive for 4 - 6 weeks.
The slow ventral root potential (VRP) and its relationship with facilitatory processes were studied in tbe spinalized frog; (Xenopus laevis).
The presence of myotonia congenita (Thomsen's disease) was demonstrated in a stud Friesland calf.
The activity of several enzymes was measured in the serum of control and hyperthermic rats.
In order to investigate the effect of constriction on the conducting ability of peripheral nerves the sciatic nerve of the South African frog (Xenopus laevis) was constricted using two different constricting mechanisms.
