[Drug addiction by inhalation of gasoline vapor. Clinical and toxicological aspects]. / Toxicomanies par inhalation de vapeur d'essence. Aspects cliniques et toxicologiques.

Following an epidemic of sniffing petrol fumes and the death of a child, the authors review published findings of this little-known type of toxicomania. They envisage the Clinical and Toxicological problems. Researching and identifying the petrol remain problems. It is possible to detect the traces of petrol directly in the blood by gaz chromatography on a capillary column coupled to flame ionisation detector but it not possible to identify the product with complete certainly. The gas liquid on a packed column detected by Fournier transformed infra-red spectrography can be given to identification with total accuracy.

Drugs as ligands of immunogenic molecules in parasites: an approach to the isolation of target-antigens.

Schistosomicide drugs are used as ligands to isolate the target antigens of schistosome by affinity chromatography. Anti-target antigens immune sera produced in rabbit permit their localization on the parasite using immunofluorescence. Target antigens of some drugs determine a relatively high immunoprotection in rat or mouse schistosomiasis infection.
