A cyto-physiological study of the G-cell secretory cycle in the antrum mucosa of the hamster and of the rat.

The secretory cycle of the antral G cell in the golden hamster and in the Wistar rat has been investigated, using classical techniques of optical and electron microscopy associated with special methods (such as goniometry, densitometry, immunohistology, morphometry) and with radioimmunoassay for gastrin. This paper confirms the secretory cycle of the G cell after refeeding. It clarifies the nature of granule polymorphism and suggests a particular mechanism of emiocytosis with sequential granule fusion. Furthermore, our investigations show some dissociations between the G cell, the parietal cycle, and the seric immunoreactive gastrin in the late phase of the secretory cycle (2 to 6 h after refeeding).

[The Cerebral Function Monitor. Description, functioning and interpretation principles].

The Monitor of Cerebral Function enables continuous monitoring of the cerebral electrical activity and this over long periods due to the slow recording speeds. The cerebral electrical signals picked up by the electrodes attached to the scalp are registered in the form of a curve which fluctuates to a greater or lesser extent depending on the recording speed. The examination of the height of the curve with respect to zero and its amplitude indicates the voltage of the cerebral activity and yields information regarding polymorphism. It is thus possible to monitor variations in cerebral activity over a prolonged period during anaesthesia as well as during the revival phase with the Monitor of Cerebral Function, the electroencephalogram being reserved as an aid to precise diagnosis and for localization and close scruting of the anomalies.

[Cerebral Function Monitor and anesthesia].

The Monitor of Cerebral Function was employed in anaesthesia for a double purpose: as a monitor of anaesthesia, of possible complications and of overdosage that might lead to cerebral damage; a bringing up to date of the comparative data on the various anaesthetic protocols. In this manner, we were able to demonstrate the during anaesthesia application of a cerebral monitor that is well designed and easy to handle. A comparative study of hypnotic anaesthetics and those that induce neuroleptanalgesia demonstrated that, in certain cases, the same anaesthetic stability is achieved when there is an early appearance of the electric silences as when the cerebral electrical activity is only slightly modified.

Combined stereotactic and peripheral surgical approach for spasmodic torticollis.

Thalamotomy with or without pallidotomy and peripheral denervation, if necessary, was performed in 14 cases of spasmodic torticollis or other late dystonias. Of 4 bilateral procedures, 2 had a good result, in 1 there was little change and in another the patient remained with a pseudobulbar syndrome, the only complication in this group. 1 patient only required peripheral denervation with a good result. Of the 9 patients who underwent unilateral thalamotomy, with or without pallidotomy, the result was excellent in 6 and good in 2 others, but in 4 of these 8 patients peripheral denervation was also performed.

[Inflammatory granuloma of the face with a malignant course. Atypical Hodgkin's disease (author's transl)].

A case of Hodgkin's disease beginning in the skin of the face with local lymph node involvement is reported. This was a lymphogranulomatous form without characteristic Reed-Sternberg cells in skin biopsy specimens, rendering the diagnosis difficult. There was a combination of granulomatous inflammation, plaques of necrosis and lesions of fibrinoid necrosis in the vessel walls. This form entered the classification of clinical Stage IV, with its associated serious prognosis.
