    Notes: Summary A subtemporal-infratemporal and basal subfrontal approach for the removal of extensive, predominantly extradural cranial base neoplasms is described. This approach was used successfully in six of our patients. The advantages of this approach are extensive exposure of the anterior and mid-cranial base as well as the clivus, direct exposure and management of the ipsilateral petrous and cavernous internal carotid artery (ICA), and access to extracranial vessels for microvascular flap transfer. Disadvantages include prolonged operative time and less control of the contralateral petrous ICA. Six patients with extensive cranial base neoplasms had operations using this technique without any mortality or major permanent morbidity. The value of this approach to patients in terms of control or cure of extensive cranial base tumours has to be proven by long term follow-up.

    Notes: [Auszug] This communication is a preliminary report of studies on two such cases (to be reported more fully at a later date). The two patients were middle-aged men in whom the diagnosis of polycythsemia was confirmed by red cell volume studies using chromium-51. The renal lesions were unilateral ...

    Notes: In a series of 250 renal biopsies (transplants excluded) the diagnosis of membranous glomerulonephritis was made in 22. This was done on light microscopy in 17, while the addition of immunofluorescence enabled the diagnosis to be made in a further five. Electron microscopy confirmed the diagnosis in all cases. Immunoperoxidase studies emphasized the basement membrane distribution of the deposits of immunoglobulin and the relative sparing of the mesangium. They showed at an ultrastructural level the presence of IgG in the deposits.

    Notes: Résumé Les conditions expérimentales déterminent la réponse rénale à l'angiotensine chez le rat. Antérieurement, on a seulement demontré une réponse natriurétique à cette hormone. Cependant, chez les rats chargés chroniquement de sodium, on a demontré que l'angiotensine en doses de 0,00005–0,005µg/kg/min est toujours anti-natriurétique. Après une opération récente, ou sous anesthésie ou en présence d'une déplétion de sodium, l'angiotensine à ces doses, chez les mêmes animaux, est soit sans effet ou même natriurétique.

    Notes: Résumé Chez les lapins auxquels on a administré du sel, l'angiotensine en doses de 0.005-0.00005µg/kg/min a réduit l'excrétion urinaire de sodium à une quantité correspondant au logarithme de la dose, tandis que des doses inférieures à 0.005µg/kg/min n'ont eu aucun effet sur la tension artérielle. Chez les mêmes lapins lors d'une déplétion de sel, de telles doses n'ont eu aucun effet sur l'excrétion de sodium. Des doses fortes (〉 0.05µg/kg/min) qui élevaient toujours la pression sanguine, provoquèrent souvent une augmentation lente de l'excrétion de sodium, beaucoup plus marquée quand l'animal était exempt de sel que lors qu'il en était pourvu. On suggère que l'angiotensine agit normalement comme une hormone qui retient le sodium, action produite par de petites quantités sans effet sur la tension artérielle.
