Effet de l'ablation partielle ou totale du tissu rénal sur l'hypertension rénovasculaire chez le rat

Summary Arterial hypertension, elicited in the rat by partial renal artery constriction, appears faster and affects more animals when the controlateral kidney is removed simultaneously. Excision of the ischemic kidney after hypertension of 1 to 3 weeks duration is not followed by any fall of blood pressure during the first 24 h. If the arterial constriction is not accompanied by controlateral nephrectomy, hypertension disappears after removal of the ischemic kidney, diminishes after bilateral nephrectomy and is increased by excision of the un-touched kidney.

Potential juvenile hormone analogues containing piperidine ring: Synthesis and biological assay on insects

Summary Some compounds containing piperidine rings have been synthesized, and submitted to biological tests on insects for their hormonal activity on pupae ofTenebrio molitor L. andBombyx mori L. Some of them display a hormoneanalogue or toxic activity.The editors do not hold themselves responsible for the opinions expressed in the authors' brief reports. — Les auteurs sont seuls responsables des opinions exprimées dans ces brèves communications. — Für die Kurzmitteilungen ist ausschliesslich der Autor verantwortlich. — Per le brevi comunicazioni è responsabile solo l'autore. — . — Solo los autores son responsables de las opiniones expresadas en estas comunicationes breves.This research has been supported by the Italian National Research Council (CNR) special ad hoc program Fitofarmaci e Fitoregolatori, Subproject. 7.Acknowledgments.
