AbstractIonically conducting materials containing PEO were prepared from telechelic di(methyl-diethoxy-silane) PEO, synthesized by the hydrosilylation of telechelic diallyl-PEO with methyldiethoxysilane. The network is obtained by the usual sol-gel chemistry. Then, it is filled with LiClO4 by diffusion of the salt and further drying. A comparison is made with the same kind of materials crosslinked using urethane chemistry. Diffusion studies show that the diffusion coefficient of solvent is similar for both types of materials, whilst the ionic conductivity is higher for the networks crosslinked with siloxane bonds. An experiment of diffusion of LiClO4 without solvent showed that this salt has a diffusion coefficient of the order of 2.10-8 cm2.sec-1 at 34°C. The conductivity calculated from this determination is compatible with the mechanism of lithium cation transport by the diffusion of salt molecules. Elasticity modulus measurements show that the salt aggregates are essentially located within the crosslinks at low concentration, but also in the PEO chains for salt concentrations higher than 1 mol/l.

SummaryThe authors report the case of a 45-yr-old male who presented from 1979 to 1986 with several severe depressive episodes. The patient fulfilled Feighner criteria for major depression, Newcastle criteria for endogenous depression: the depressive episodes were all classified as severe recurrent depression without melancholia according to DSM III. The patient was resistant to different types of treatment (ECT, tricyclic and MAOI drugs, lithium, sleep deprivation). With a treatment of 10 cg/day of fenetyline, reduced to 5 cg/day after 6 months, (atypical manic episode), the patient improved considerably for 20 rnonths. The therapeutic response decreased after this period but after a month of withdrawal, the patient again responded. The authors cannot explain the duration of this therapeutic response.

1. Outward bumetanide-sensitive Na+-K+ co-transport was studied in the erythrocytes of 51 subjects, 24 normotensive subjects and 27 hypertensive patients, matched for sex and age. 2. Three kinetic parameters of this cation transport system were considered: velocity of efflux at saturating internal sodium (Nai) concentrations (Vmax.), apparent affinity for sodium (K50%) and index of co-operativity among Nai sites (Hill's n). 3. We correlated these values with clinical and laboratory data determined routinely in hypertension. 4. There were no significant differences between normotensive and hypertensive subjects for the values considered and we did not find any significant correlations between co-transport and clinical data.
