    Notes: [Auszug] Starting from this hypothesis, I have made extracts of relaxed vessel muscles using water or salt solutions of ionic strength either lower than that in the intra-cellular fluid or equal to it. The muscle of the relaxed cow carotis was separated from other tissues. Then it was minced in a small meat ...

    Notes: [Auszug] IT was shown earlier1, that after section of a cholinergic nerve (the cervical sympathetic of the sheep) choline acetylase rises much above the normal concentration in the proximal trunk while, coincident ally, it falls steeply in the distal trunk. Unlike true cholinesterase2, lipolytic esterase5 ...
