the paper contains the first report on the biology of snail-killing flies (sciomyzidae) in khuzestan. it is based on field and laboratory studies conducted during november 1971 and april 1973, as well as field observations in may 1972, at the dezful medical research station. additional biological information obtained during studies is given for pherbellia fuscipes (macaquart), p.grisescens (mei...

A radio assay employing 14C-uridine to measure the intracellular killing of Candida albicans by phagocytes is presented. The principle of this new method is that after killing of Candida albicans by phagocytes RNA synthesis stops and therefore uridine uptake is diminished whilst viable candida in cultures would take up uridine and as a result, high CPM counts can be obtained within 135 min...

Killing appears to perpetuate itself even in the absence of retaliation. This phenomenon may occur in part as a means to justify prior killing and so ease the threat of prior killing. In addition, this effect should arise particularly when a killer perceives similarity to the victims because similarity should exacerbate threat from killing. To examine these ideas, the authors developed a bug-ki...
