Unlabelled: The objective of our survey is to value the availability of the antidotes in the main Moroccan hospitals., Material and Method: A questionnaire constituted of 15 items and permitting to appreciate the availability of 43 antidotes selected in the literature, has been addressed to 9 hospitals of which 3 soldiers., Results: Five per cent of the antidotes were available in all hospitals having answered to our questionnaire. Forty two per cent of the antidotes missed to all structures, the rest (47%) had a variable availability according to the structures. The list of the missing antidotes is long and contains classified vital products of group A of the recommendations of the IPCS (International Program on Chemical Safety) like the specific antibodies of the digoxine and the methylene blue., Conclusion: The found results are troubling and often unveil sometimes a big problem of management of these products vital and constituent the unique treatment.

Iodine-deficiency disorders are a major problem of public health in Morocco. To mitigate this deficiency, the iodination of all the salt intended for human consumption in a proportion of 80 +/- 10 mg/kg of salt has become obligatory since a decree published in 1995. We estimated that this rate of iodized salt issued risked inducing an iodine excess in the population. To check this hypothesis, we provided 7 families made up of 28 subjects, who at the start were consuming a non-iodized salt, with the decreed, iodized salt and we followed the evolution of their urinary iodine excretion over a period of 3 weeks. The mean values of urinary iodine excretion of the 28 subjects were 12.8 micrograms/dl before use of iodized salt and 26.8, 35.5 and 63.2 micrograms/dl, respectively, after 7, 14 and 21 days from the introduction of iodized salt into their diet. After 21 days of the use of iodized salt, 84.6 per cent of the subjects had an iodine excess. We conclude that prolonged use of this iodized salt exposes the population to the risk of thyroid disorders.

Baclofen (4-amino-3-(4-chlorophenyl)butyric acid) is the only selective agonist for GABA-B receptors. Its R-(-)-enantiomer is about 100 times more active than the S-(+)-enantiomer. In the search for new compounds that bind to GABA-B receptors, it is very important to clarify the structural requirements. The authors report the synthesis and separation of isomers of various 3-heteroaromatic (benzo[b]furan and thiophen) aminobutyric acids. The 4-amino-3-(7-methylbenzo[b]furan-2-yl)butanoic acid is a potent and specific ligand for GABA-B receptors, with an IC50 value of 5.4 microM for the displacement of [3H] GABA.
