43,933 | Modulating effect of body temperature on the toxic response produced by the pesticide chlordimeform in rats | Watkinson, WP; Highfill, JW; Gordon, CJ | 1,989 | Previous studies from this laboratory have demonstrated significant deficits in cardiovascular function in rats exposed to the pesticide chlordimeform (CDM) when body core temperature (TCO) was maintained at 37 degrees C. To investigate the role of TCO on CDM toxicity, similar experiments were conducted over a range of... | 0 |

52,740 | Elicitation of lignin biosynthesis and isoperoxidase activity by pectic fragments in suspension cultures of caster bean | Bruce, RJ; West, CA | 1,989 | ABSTRACT Suspension cultures of castor bean (Ricinus communis L.) which have been treated with pectic fragment elicitor rapidly accumulate lignin as measured by derivatization with thioglycolic acid. The responsiveness of cultured cells to elicitor is dependent on the stage of culture growth. In 6-day (maximally resp... | 0 |
