Über einige vegetative Reaktionen nach Geruchsreizen beim Menschen

Summary The galvanic skin response in man has been found to be altered by olfactory stimuli. A reduction in skin resistance, which is dependent upon the strength of the stimulus, can be seen after a few seconds, returning to the original level after several minutes. Respiratory rate, blood pressure, and pulse rate are likewise influenced.

Experimenteller Nachweis der autochthonen Automatie der Lymphgefässe

Summary It is shown that the peristaltic activity of the isolated mesenterial-lymph vessels of mammals (Cavia porcellus L.) is provoked by two different stimuli:1. by extension (internal pressure of the vessel: 2–25 cm H₂O); 2. by temperature (biokinetic Temperature-Space of 23°; between 22–45°C).Based on these experiments, the autochthonous automaticy of the lymph vessels has been proved.

Die Verstärkung der pressorischen Vasopressin-Reaktion durch 2-Mercaptoäthylguanidin bei der Ratte

Summary 2-mercaptoethylguanidin enhances the blood pressure responses to small doses of vasopressine in the rat. This potentiation is statistically significant. The increase of the vasopressine reaction after 2-mercaptoethylguanidin is not due to an indirect effect of vasopressine on the cardiovascular system.

Functional anatomy of frog's taste organs

Résumé Dans les bourgeons gustatifs deRana pipiens deux groupes de cellules ont été découverts. Le premier est directement en relation avec la réception de stimuli, tandis que le second ne comprend que des cellules d'association. Les cellules sensorielles offrent des contacts synaptiques avec les fibres sensorielles.

Die Blutdruckwirkung des N-Isopropyl-nor-adrenalins

Summary N-Isopropyl-nor-adrenaline (aleudrine), which normally reduces the blood pressure, exerts after treatment with parasympathetic stimulants, especially after pilocarpine, an increase of the blood pressure, which is considerably stronger than that produced by adrenaline. This pressor effect of aleudrine is, contrary to the hypotensive action, cholinergic as it is abolished by atropine, whereas it remains fully unaffected by nicotinization. The pressor effect of aleudrine thus corresponds to the analogous action of choline, the mechanism of which was elucidated byForst.

Fehlerkorrekturen bei stereologischen Messungen an menschlichen Plazenten:2. Die Schnittstauchung

Summary Irreversible compression of the sections, due to cutting on the microtome, which may attain up to 20% in thin paraffin sections, does not influence stereological measurings of volume per cm³ of human placental villi. The measured villous surface, however, must be corrected by multiplication with 1/(1+q/2), whereq means the percentage of compression, expressed as decimal fraction.

Production of lesions in various tissues by amino acids

Zusammenfassung Es wird der Einfluss einer Aminosäure auf verschiedene Gewebsarten und auch auf die Haut kontrolliert. Unterschiedlich starke, z.T. schwere Degenerationen, Entzündungen und auch Zellauflösungen waren festzustellen. Teilweise kam es zu Riesenzellbildungen oder zu Fibrosen in der Leber. Knochennekrosen und Blutungen wurden festgestellt.
