Activity ratio of adrenaline to noradrenaline in various colour reactions.
Toshiyuki Ozaki (尾 崎 俊 行) From the Department of Physiology, Nagasaki University School of Medicine, Nagasaki (Received for publication, March 1, 1955) In estimating adrenaline content of the adrenal medullary tissue or of the adrenal venous blood, various colour reactions have been applied, ad renaline being used as the reference standard. However, it is generally accepted that noradrenaline i...
متن کاملAn action of 5-hydroxytryptamine on adrenaline receptors.
Contractions of isolated strips of cat spleen due to 5-hydroxytryptamine, adrenaline, histamine and acetylcholine were antagonized by phenoxybenzamine. Responses to both 5-hydroxytryptamine and adrenaline were not blocked in strips which were protected by a high concentration of either 5-hydroxytryptamine or adrenaline throughout exposure to phenoxybenzamine. The contraction due to a large dose...
متن کاملAdrenaline and noradrenaline concentrations in rat tissues.
Noradrenaline and adrenaline concentrations have been little studied in rat tissues; this paper deals with their estimation by an extension ofthe method of Weil-Malherbe & Bone (1952, 1953, 1954) for blood; a brief report has already been presented (Montagu, 1955). The results do not appear to support the current hypothesis that the concentration of noradrenaline can be correlated with the dens...

Adrenaline and noradrenaline in cerebrospinal fluid.
The occurrence of adrenaline and noradrenaline in human cerebrospinal fluid (C.S.F.) has not yet been demonstrated. In this note figures for the concentration of these amines in C.S.F. are presented. Since the analysis required a substantial volume of C.S.F., i.e., 15 to 20 ml., the estimations were carried out on specimens withdrawn during air encephalography and came from patients with a susp...
