[A precursor of phospholipids in the treatment of severe traumatic comas]. / Etude d'un précurseur des phospholipides dans le traitement des comas traumatiques graves.

CDP Choline, a metabolic precursor of phospholipids, has been tested against placebo in a controlled randomized double blind study concerning 60 cases of severe head injuries (wide-spread cerebral contusions and/or severe concussion). In the treated group, a shortening of the comatose period and an acceleration of neurological deficits recovery have been observed. These results are tentatively attributed to an effect of the drug against brain edema, already documented on experimental models.

[Levels of axial lesion in severe head injuries (author's transl)]. / Les niveaux de souffrance axiale du traumatisme cranien grave. Etude critique.

Over the past few years considerable amount of clinical syndromes describing brain stem levels of lesion were reported. This work was undertaken to establish, if possible, a simplification of criterions of axial lesions in head injuries. 125 patients with severe head injuries were strictly selected. Statistical analysis of careful examination of clinical pattern was performed and correlated, when possible, with anatomical lesions. Only four homogeneous groups were isolated:--group I represents the cortico-sub-cortical level,--group II représents the diencéphalie level,--group III represents the upper brain stem level with two subdivisions dependent upon the mechanism of herniation : central or uncus,--group IV represents the lower brain stem level.

Direct high-performance liquid chromatographic resolution of the enantiomers of tiaprofenic acid using immobilized human serum albumin.

Resolution of racemic tiaprofenic acid (TA) has been performed using immobilized human serum albumin as the stationary phase. The eluent was phosphate buffer-acetonitrile-n-octanoic acid (90:10:0.015, v/v). Detection was achieved at 305 nm. The pharmacokinetics of the enantiomers were studied following oral administration into humans and after subcutaneous injection in rats. Plasma concentrations of (+)-TA were much greater than those of (-)-TA. For the rat, the pharmacokinetic parameters between (-)-TA and (+)-TA were all statistically different (p < 0.005).
