IN 1939, Lissak1 showed that extracts of sympathetic nerves contained a Sympathomimetic substance with an adrenaline-like action on various biological preparations. In a series of papers, von Euler2,3,4 has demonstrated that this type of extract is largely noradrenaline. His chief sources of material were cattle and horses. Lissak5 further showed that if a postganglionic sympathetic nerve was stimulated electrically, and the cut end of the nerve allowed to hang beneath the surface of acidified…

Resistance to the Potato Root Eelworm, Heterodera rostochiensis Wollenweber

The search for resistance to the potato root eelworm among the South American tuber-forming Solanum species in the Commonwealth Potato Collection is now practically complete, and more than 1,200 lines, belonging to more than sixty species, have been found to be resistant.

A Specific Sympathomimetic Ergone in Adrenergic Nerve Fibres (Sympathin) and its Relations to Adrenaline and Nor-Adrenaline

Summary. Extracts have been prepared of various kinds of nerves and their content of sympathomimetic activity determined and the actions analyzed. The thoracic and lumbar sympathetic chain and

l-norAdrenaline in the Suprarenal Medulla

The present report confirms the findings of the previous report that adrenal medullary tumours contain a high proportion of noradrenaline, and confirms these findings with the use of different techniques.

The Presence of a Substance with Sympathin E Properties in Spleen Extracts

The similarity between the action of the purified spleen extracts and the postulated sympathin E on the one hand and nor-adrenaline or D. N. E. on the other is pointed out.

A Sympathomometic Pressor Substance in Animal Organ Extracts

It was observed that most organs contain considerable amounts of a pressor substance different from piperidine, which is likely to be a normal constituent of urine.

Noradrenaline in Adrenal Medullary Tumours

BLASCHKO1 has suggested the stages by which adrenaline can arise from tyrosine, the final stage being the N-methylation of the primary amine noradrenaline. It is possible that this last stage occurs
