Abstract：
:Two methods of measuring body temperature were compared in common marmosets. Subcutaneous temperatures were measured remotely via previously implanted subcutaneous microchips (Plexx BV, IPTT-100) prior to measurement of rectal temperature using a conventional rectal probe. Marmosets were treated with saline or the brain penetrant, 5-HT1A/B/D receptor agonist SKF-99101H (3-(2-dimethylaminoethyl)-4-chloro-5-propoxyindole hemifumarate) (0.3-3 mg/kg SC), which has previously been shown to induce hypothermia in guinea pigs. Body temperature was sampled immediately before drug administration and at 30-min intervals thereafter for a period of 2.5 h. SKF-99101H dose-dependently induced hypothermia in the common marmoset and there was close agreement between rectal and subcutaneous body temperatures, with an average difference in absolute body temperature of 0.26+/-0.02 degrees C. The data show that subcutaneously implanted microchips provide a simple, reliable measure of body temperature in common marmosets which is sensitive to pharmacological intervention, minimizes handling induced stress, and is minimally invasive.
