2-Amino-6-trifluoromethoxy benzothiazole (PK 26124) prevented convulsions induced in rodents by maximal electroshock, inhibitors of the synthesis of gamma-aminobutyric acid (GABA) and ouabain, but was inactive against seizures provoked by GABA antagonists, unlike diazepam, chlordiazepoxide, phenobarbital and valproic acid. 2-Amino-6-trifluoromethoxy(More)
Two models have been chosen to study the effect of 2-amino-6-trifluoromethoxy benzothiazole (PK 26124) on excitatory amino acid neurotransmission: the pool of cyclic guanosine monophosphate (cGMP) in the cerebellum and the release of acetylcholine in the striatum and olfactory tubercles. The release of acetylcholine induced by N-methyl-DL-aspartate in the(More)
A symbiotic bacteroid matroclinously transmitted is present in the ovocytes and the follicular cells of the sub-species Porcellio dilatatus petiti of the Saint-Honorat island, as well as in all hybrid females born from a petiti mother. It is absent in the Porfellio dilatatus dilatatus females (population of Poitiers) and this seems to cause the lithality in(More)
The authors studied 65 men who had a varicocele by semen analysis, estimating the levels of FSH, LH, testosterone and prolactin and in some cases the rise in FSH using GnRH. 59 cases were treated by operation and in each of these testicular biopsy was carried out on both sides. Indications are given as to the duration in years of the infertility, the(More)
The investigations on the activity of respiratory ciliae in vivo are of considerable interest for the study of physiopathological disorders resulting from chronic infection or inhaled pollutants. We present an image analysis method for the measurement of ciliary beat frequency on mammal or human in vivo samples. Videofilm sequences of samples placed under(More)
One hundred and seventeen shoulders in 113 patients were treated surgically for recurrent anterior dislocation of the shoulder by the Latarjet procedure - transplantation of the coracoid process to the anterior border of the glenoid fossa. 67 p. 100 of the patients engaged in sport and 33 p. 100 did not. The usual lesions found at operation were separation(More)
