Regulatory requirements for biocides on the market in the European Union according to Directive 98/8/EC.

In early 1998, the European Commission and Parliament adopted a new Directive concerning the placing on the market of biocidal products. The Directive is to be implemented in the member states by May 2000. The member states are currently concerned with the national implementation into legislation whereas the Commission is setting up the proposal for a review programme for the existing active substances and the products in which they are used. This paper describes the effort currently undertaken (up to the end of December 1998) to define the procedures to be used and characterise the substances covered.

[Critical study of electric activity of the small intestine in the dog].

Thanks to a cross-circulation, the authors caused to survive in the abdomen of a sacrificed dog, the whole of the small intestine, the motor activity of which was analysed by electro-enterography. This experimental preparation thus eliminates polygraphic recordings of all potential variations outside the small intestine, e.g. stomach, colon, diaphragm, muscle, myocardium. One thus obtains very pure tracings of the variations of potential originating in the small intestine, recorded from bipolar serous intestinal electrodes, they show the activity of the small intestine, consisting of a permanent basal electric rhythm on which are grafted spikes contemporary of motor phenomena. In the abdominal skin there were recorded only a cutaneous slow wave which was contemporary with the deep motor phenomena.
