Ethoxylated rapeseed oil derivatives as novel adjuvants for herbicides.

Ethoxylates of rapeseed oil and of methylated rapeseed oil were synthesized and tested as adjuvants for 2,4-D and phenmedipham. Provided they had less than 6 units of ethylene oxide (EO), 1.0 to 10 g litre(-1) ethoxylates in water induced droplet spreading on barley leaves.

Modulation by alcohol and methadone of 2-deoxyglucose-stimulated pancreatic secretion in the rat.

Alcohol intake is a major problem in drug addicts, and it is not clear whether the effects of alcohol and opiates are additive or potentiating. Vagally stimulated pancreatic secretion in rats is potently inhibited by opiates acting centrally at mu-receptors. In the present experiments, we determined the effects of methadone on 2-deoxyglucose (2DG)-stimulated pancreatic secretion in rats treated with acute (1.

[Drug addicts in the Netherlands].

Dutch Government admit that tolerate attitude toward lower-risk drug abuse could reduce criminality and protect drug addict's health. Some Dutch psychiatrists disagree and try to struggle against this so called "normalization" politic. Morphine legal consumption, per million inhabitants is higher in Netherlands than in France, showing a certain latitudinarianism of health profession.

[Effect of nalbuphine on external pancreatic secretion in rats].

Pancreatic secretion is controlled by neural and endocrine mechanisms. The administration of 2-desoxyglucose (2DG) to rats stimulates pancreatic secretion through a mainly vagal pathway, and provides an useful pharmacological model to study the agents (especially opiates and adrenergic drugs) which can modulate this neural pathway. In the present study, basal and 2DG-stimulated pancreatic secretion were measured in anesthetized rats.

[Multiple drug addiction].

The "polydrug use" well known at the USA, has sprayed in France and Europe during the last ten years. Harms of polydrug use were pointed out by some specialized centers. The aim of this work is to emphasize the dangers of the abuse of some drug associations.
