SEXUAL DIMORPfflSM IN THE ACCESSORY OLFACTORY BULB AND VOMERONASAL ORGAN OF THE GRAY SHORT-TAILED OPOSSUM, MONODELPHIS DOMESTICA... 

This study was designed, therefore, to determine if there is sexual dimorphism in the volume of the AOB and VNO of the Brazilian gray short-tailed opossum. To accomplish this, we determined the volumes of the sensory epithelium of the VNO, and of the mitral/tufted layer as well as the anterior and posterior halves of the nerve fiber/glomemlar layer of the AOB.

Dogs, rats, and rabbits metabolize fluoroacetate compounds to nontoxic metabolites, and excrete fluoroacetate and fluorocitrate compounds peak rate of excretion occurs during the first day after dosing and drops shortly thereafter. Rats dosed with radiolabeled 1080 at 5.0 mg/kg BW had 7 different radioactive compounds in their urine. Monofluoroacetate comprised oifly 13% of the urinary radioactive material, fluorocitrate oifly 11%, and an unidentified toxic metabolite 3% 2 nontoxic metabolites accounted for almost 73% of the urinary radioactivity. Animal muscle usually contained nondetectable residues of any 1080 component within 1-5 days of treatment. Defluorination occurred in the liver by way of an enzymic glutathione-dependent mechanism which in the brush-tailed opossum resulted in the formation of 5 -carboxymethylcysteine and free fluoride ion. A rapid rate of defluorination together with a low reliance on aerobic respiration favored detoxification of fluoroacetate rather than its conversion into fluorocitrate, and may account for the resistance of reptiles to 1080 when compared to mammals.
