Zur Frage der Beziehungen zwischen Anfällen von Spasmophilie und ultravioletter Sonnenstrahlung

With reference to a communication ofW. Morikofer (Exper.5, 86 [1949]) concerning some remarks on our own communication about the relation between U.V. light and spasmophilic convulsions (Exper.4, 279 [1948]) we point out that:— (1) Our estimations concern not only the radiation of the sun, asMorikofer erroneously assumes, but also the radiation of the sky. (2) The indoor climate is not necessarily a mediator between the open-air climate and the organism; our hypothesis of inhalation of activated substances is not the only possible explanation, however the alimentary mediation of U.V. light is still quite accepted. (3) A causal relation between the meteorological element and convulsions is not derived from the numerical relation, but from clinical and experimental knowledge, which is discussed; and never is the relation said to be necessarily a direct one. (4) Our investigation is a statistical and clinical, not an experimental one. This may be performed by others.
