Evolution of HIV infection was studied in 480 hemophiliacs A and 78 hemophiliacs B treated in the "Centre-West" Region. 23.3% hemophiliacs A and 46.

Different effects of halothane on diaphragm and hindlimb muscle in rats.

The effects of halothane administration on diaphragm and tibialis anterior (TA) muscle were investigated in 30 anesthetized mechanically ventilated rats. Diaphragmatic strength was assessed in 17 rats by measuring the abdominal pressure (Pab) generated during supramaximal stimulation of the intramuscular phrenic nerve endings at frequencies of 0.5, 30, and 100 Hz.

[Immunohistochemical study of 4 cases of mucoid and argyrophilic carcinoma of the breast].

Three to 5% of breast carcinomas are argyrophilic, including some which are mucinous and thus "composite", whereas there are no argyrophilic cells in normal breast nor in benign breast pathology. This raises the problem of the origin and type of these argyrophilic cells. We carried out a histologic and immunohistochemical study in 4 such cases of mucoid tumors containing at least 50% argyrophilic cells.
