| binding of insecticides to serum proteins in mosquitofish (gambusia affinis). | incubation of various organochlorine insecticides with mosquitofish serum leads to their association with, primarily, the vitellogenin/lipoprotein and albumin fractions. a significant variation in the quantity of each insecticide bound in the particular fractions was observed. binding appeared to increase with compounds of increasing polarity, suggestive of protein binding. preincubation of serum with endrin or aldrin significantly reduced the quantity of [3h]ddt subsequently bound while the rev ... | 1985 | 2861033 |

| on the relationship between alcohol narcosis and membrane fluidity. | we have examined the relationship between membrane fluidity and the alcohol-induced loss of righting reflex at different temperatures using the fish gambusia affinis. the potency of ethanol and hexanol increased dramatically with temperature. ethanol-induced narcosis could be antagonized by a reduction in incubation temperature. both an increase in temperature and the addition of ethanol caused an increase in membrane fluidity. however, membrane fluidity itself did not correlate with narcosis an ... | 1982 | 6897749 |
