Circadian change of sweating rate measured locally by the resistance hygrometry method in man.

There existed circadian change in the sweating rate locally measured from the anterior of the left thigh: the sweating rate showed a remarkable decline during the period 2.00--5.00 h, while at other times throughout the day it generally remained high. This reduction seemed to be independent of sleep or sleeplessness.     

The effect of temperature on the respiratory function of coelacanth blood

Zusammenfassung Die Sauerstoffdissoziationskurve vomLatimeria-Blut zeigt eine grössere Affinität zu Sauerstoff bei 15°C (P₅₀=2–3 mm) als bei 28°C (P₅₀=18.0 mm). Diese Unterschiede und die geringe Sauerstoffkapazität sind für eine Diskussion über das Überleben des Fisches beim Aufsteigen aus grosser Tiefe an die Gewässeroberfläche massgebend.     

Effect of prostaglandin E1 on cholesterol biosynthesis in rat liver

Riassunto La prostaglandina E₁ (PGE₁) ha un duplice effetto sulla sintesi epatica del colesterolo: a basse concentrazioni determina un incremento della incorporazione di acetato in colesterolo, mentre a concentrazini superiori a 50 nmoli essa determina una riduzione di questo paramentro.     

A quantitative investigation of the response to injury of the central nervous system of rats treated with ACTH and triiodothyronine

Résumé Une êtude quantitative des effets de ACTH et T3 sur la réaction des cellules gliales dans le corpus callosum, après incision, a montré que ces 2 hormones n'ont aucun effet sur cette réaction. Ainsi, on ne peut plus soutenir l'idée généralement acceptée que ces hormones provoquent une régénération partielle de l'axone central du système nerveux, en modifiant la cicatrice gliale.
