    Notes: A minialurized method of determining the toxicity of pesticides to large numbers or soil mitroorganisms is described. Bacteria. actinomycetes, yeasts, fungi and algae can be used as test organisms. A modification of the method allows determination of minimum inhibitory concentrations of pesticides to specific microorganisms. Some results obtained with herbicides are presented.

    Notes: Abstract Spiperone reduced latency to feed and prolonged the total duration of feeding in a foodpreference test in which novel and familiar foods were presented simultaneously to food-deprived rats. The increase in feeding duration could be accounted for in terms of an increase in time devoted to eating the novel foods, leaving the time devoted to eating the familiar food relatively unaltered. However, closer analysis of the data revealed that, at the level of mean duration of individual eating episodes, spiperone prolonged the eating-episode duration equally for both novel and familar foods. This apparent paradox was resolved by noting that whilst spiperone did not alter the number of eating episodes in the test, it did alter the ratio of eating episodes in favour of novel foods. The data was incorporated into a control system model which depicts actions of spiperone in the food-preference situation with total eating duration as the final behavioural output.

    Notes: Surface modification of cellulose acetate dialysis membranes was carried out by 60Co radiation induced graft copolymerization of the hydrogel, hydroxyethyl methacrylate (HEMA). The degree of grafting was controlled by varying the HEMA monomer concentration in the grafting solution and the radiation dose. A continuous flow platelet adhesion test was designed which allows testing under conditions more closely approximating hemodialysis than other small scale in vitro tests. Platelet adhesion on treated membranes fell substantially with increasing surface HEMA concentration. The presence of HEMA on the membrane surface did not affect the membrane activated clotting times significantly.
