Abstract


1. Perivascular nerve longitudinal muscle preparation and perivascular nervecircular muscle preparation were prepared from the isolated tortoise intestine.
2. The stimulations of perivascular nerve in both preparations produced contractions of the muscle strips.
3. The motor responses of longitudinal muscle strips to perivascular nerve stimulations were not affected by treatment of the strips with atropine, physostigmine weakened by treatment with regitine, propranolol, guanethidine little affected by chlorisondamine. The same preparations obtained from reserpine pretreated tortoise showed almost same response as that of the control animals.
4. The motor responses of circular muscle strips to perivascular nerve stimulation were weakened by treatment of the strips with atropine; remarkably strengthened by treatment with physostigmine; weakened by regitine, propranolol, guanethidine, chlorisondamine. The same preparations obtained from reserpine pretreated tortoise showed less contractile response than that of the control animals.
5. The above data indicate that the perivascular nerves to the longitudinal muscle contain adrenergic fibers and the perivascular nerves to the circular muscle contain adrenergic and cholinergic fibers, which are functionally excitatory.
