[Interference of minovine (a Vinca minor alkaloid) on hospital emergency toxicologic tests for derivatives of 5H-dibenzo(b,f)azepine]. / Interférence de la minovine (alcaloïde de Vinca-Minor) au cours de la recherche des dérivés de la 5-H-dibenzo-(b,f)-azépine en toxicologie hospitalière d'urgence

The authors report the possible interference due to minovine when seeking tricyclic antidepressant derivatives in biological material or pharmaceutical substances. However, their work has shown that kinetic studies using absorption spectrophotometry of the colouration obtained with phosphoric-ceric reagent and thin layer adsorbant chromatography make it possible to eliminate the doubt and identify the Vinca-Minor alkaloid.

[Evolution of serum copper and zinc levels in burn patients (author's transl)]. / Evolution des concentrations sériques du cuivre et du zinc chez le brûlé

The study of copper and zinc in 35 patients, over periods of up to 21 days following thermal injury, is marked by an important and early fall in serum copper and zinc levels. The maximum intensity of the biological disturbance appears about two days after the injury. Reversion to near normal values coincides with recovery from the large part of the lesions. The comparison of the evolution of serum levels does not permit any definite relationship to be established between copper and zinc metabolism.
