using titrations of acetylcholine ( ach ) on guinea-pig ileum the authors have demonstrated that there is no significant statistical difference between the cholinergic activity of extracts of 150 mg of retinal tissue from pilocarpinised eyes ( 0.3 mug of ach ) and the activity of extracts from control eyes not subjected to pilocarpine ( 0.29 mug of ach ) .
