Nine refinery streams were tested in both chronic and initiation/promotion (I/P) skin bioassays. In the chronic bioassay, groups of 50 C3H/HeJ mice received twice weekly applications of 50 microl of test article for at least 2 years. In the initiation phase of the I/P bioassay, groups of CD-1 mice received an initiating dose of 50 microl of test article for 5 consecutive days, followed by promo...

A modified version of a simplified in vivo test was applied to assess the susceptibility of Plasmodium falciparum to chloroquine among semi-immune febrile children in Kouroussa, Guinea. In 27% of cases, a partial response (RI/RII) to chloroquine was observed; the remainder showed a good response (S/RI). This test is both practical and useful to assess the efficacy of chloroquine at the intermed...

toxicity of spinosad was primarily evaluated with three bioassay methods: feeding, spraying (residual exposure) and combination with larval medium against one susceptible and one field population. feeding method was selected as efficient method for survey of susceptibility or resistance of seven field populations. in feeding bioassay method, spinosad ld50 of susceptible strain at 24h and 72h we...

NCBI’s PubChem BioAssay database (1-5) (http://pubchem.ncbi.nlm.nih.gov) is a public repository for archiving biological tests of small molecules and siRNA reagents. Small molecule bioactivity data contained in the BioAssay database consist of information generated through high-throughput screening experiments, medicinal chemistry studies, chemical biology research, as well as literature curati...
