differential potentiation by nystatin of the effect of antibiotics on yeast and mammalian cells. | the effect of the polyene antibiotic nystatin, used in combination with several other antibiotics, on the membranes of candida albicans sc#8169 (yeast) cells and of chinese hamster ovary and 3t3 (mammalian) cells was investigated. it was concluded from determinations of the viability of the yeast cells and from measurements of deoxyribonucleic acid synthesis by the mammalian cells that nystatin acts synergistically with several antibiotics on yeast cells, but not on cho and 3t3 cells. this selec ... | 1975 | 1171651 |
time-dependent changes in commissural field potentials in the dentate gyrus following lesions of the entorhinal cortex in adult rats. | previous neuroanatomical work has shown that lesions of the entorhinal cortex in adult rats cause the commissural projections to spread from their normally restricted locus in the inner molecular layer approximately 40-50 mum into the outer molecular layer (that is, into the zone deafferented by the lesion). in the present study we measured the effects of the entorhinal lesion on the distribution of short-latency potentials elicited by commissural stimulation in the molecular layer. studies with ... | 1975 | 1175043 |
endogenous prostaglandin release contributes directly to coronary artery tone. | an in vitro coronary artery preparation of beef heart was found to synthesize and release continuously large amounts of a prostaglandin of the e type. inhibition of prostaglandin synthesis with aspirin, indomethacin, or eicosa-5,8,11,14-tetraynoic acid induced a sustained contraction of the coronary artery, and pretreatment with indomethacin diminished markedly the output of prostaglandin into the bathing medium. it appears that prostaglandin e1, generated from within the vessel wall itself, may ... | 1975 | 1175084 |
