The mean ChAc activity (μg of ACh/g acetone-dried tissue/1 hr.) in the guinea-pig brain was 3954 and in the rat brain 4205; in the guinea-pig heart atria it was 99 and in the rat atria 687; in the guinea-pig duodenum and proximal part of the jejunum it was 1855 and in the rat duodenum and proximal part of the jejunum 219; in the distal part of guinea-pig ileum it was 1331 and in the distal part of rat ileum 253; in the guinea-pig uterus it was 9 and in the rat uterus 68; in the guinea-pig diaphragm it was 127 and in the rat diaphragm 262; in the guinea-pig gastrocnemii muscles it was 112 and in the rat gastrocnemii muscles 82.Mean content of ACh (μg of ACh/g of fresh tissue) in the guinea-pig duodenum and proximal part of the jejunum was 7.93 and in the rat duodenum and proximal part of the jejunum 3.39; in the distal part of the guinea-pig ileum it was 7.0...
