STUDIES ON THE CONTROL OF HIGHER AND PERIPHERAL AUTONOMIC SYSTEMS OVER THE ACTION OF CHOLINE AND CHOLINESTERASE
PART Ⅱ. ON THE REGULATING CONTROL OF HIGHER AUTONOMIC SYSTEM OVER THE ACTION OF SERUM CHOLIN AND CHOLINESTERASE.

Herewith introduced various responses of s-ch and s-ch E after stimulation of autonomic nervous centre (by Kurotsu's sting) or after operations like peripheral sympathectomy or vagotomy in rabbit.
1) S-ch E decreases after stimulation of b-sympathectic zone.
2) S-ch E increases after stimulation of c-parasympathctic zone.
3) S-ch E increases after stimulation of c-parasympathetic zone. Stimulation of c-parasympathetic zone acts as moment for increasing s-ch E as well as s-ch. This phenomenon of parallelismus is usually apparent soon after the stimulating sting.
4) After sympathectomy (splanchnicectomy), increases serum cholinesterase (s-ch E) is usual and it returns to the preoperative level 4 weeks later.
5) After the parasympathectomy (vagotomy) decrease of s-ch E may usually be observed, and 4 weeks later it comes back to the preoperative leveI.
6) S-ch E activity may easily be influenced by peripheral sympathectomy or vagotomy as weII as by stimulating sting of c-parasympathetic or b-sympathetic zone of Kurotsu.
