liv ANNUAL REPORT the department to buy an Aminco-Bowman speetrophotofluorimeter and we can now estimate minute amounts of each fluorescent amine in their mixture Professor Brownlee Mr Carlyle and Mr Johnson were concerned with the release of active substances from smooth muscle and their estimation Mr Carlyle described novel nerve-muscle preparation which proved useful in identifying the mechanism of action of depolarizing drugs Mr Johnson identified and described specific ganglionic site of action of 5-hydroxytryptamine in the guinea-pig small intestine Dr Paterson continued his investigations of the actions of catechol amines on striated muscle and with Mr Huskisson investigated the nature of the dual action of depolarizing neuromuscular blocking agents The mode of inhibition of intestinal muscle by stimulation of adrenergic nerves and by sympathomimetic amines was carried further by Dr Wilson who advanced evidence for novel site of action of adrenaline in smooth muscle Dr Birmingham's researches were on the effects of spasmolytic drugs on phosphorylase activity in smooth muscle and on the anti- thrombotic action of some amine oxidase inhibitors department of physiology Number of Students 249 γ4 ivftW ί 33 Ancillary 10 Sc Special ph ia aetk Total 305 Results of Examinations Sc Special 1st Class 2nd Class Upper Division 2nd Class Lower Division Higher Degrees Ph Lewis study of induced broncho-constriction in the guinea-pig Ph Sani Reactions of isolated arteries to some pharmaco- logical and physical stimuli
