Loperamide is an over-the-counter antidiarrheal with opioid-receptor agonist properties. Recommended over-the-counter doses (range = 2-8 mg daily) do not produce opioid effects in the central nervous system because of poor oral bioavailability and P-glycoprotein efflux* of the medication (1); recent reports suggest that large doses (50-300 mg) of loperamide produce euphoria, central nervous sys...

OBJECTIVES The purpose of this study was to describe differences in childhood pesticide exposures between counties on the Texas-Mexico border and nonborder counties. METHOD The authors reviewed all pesticide exposures among children younger than 6 years reported to the South Texas Poison Center during 1997 through 2000. RESULTS Nonborder counties had twice the reported exposure rate of bord...

nuated blood, with the altered character of its elements; the dilatation of the pupils; the foaming at the mouth; and the general lethargy, followed by convulsions and death. J This is not a poisonous snake. It is known also, in Bengal, as Betaehra. The term lineatus has been suggested by Dr. Sircar, because of the resemblance of the snake to the one described under that namely Russel at page 3...

Urushiols are the allergenic components of Toxicodendron radicans (poison ivy) as well as other Toxicodendron species. They are alk-(en)-yl catechol derivatives with a 15- or 17-carbon side chain having different degrees of unsaturation. Although several methods have been developed for analysis of urushiols in plant tissues, the in situ localization of the different urushiol congeners has not b...

Strategies for the control of vertebrate pest are identified using mathematical models of poisoning. The models integrate aspects of foraging ecology and toxicology in a probabilistic framework. The structure, assumptions and control implications of the models are presented. Variables (control parameters) influencing the probability that a pest animal dies in a poison programme are identified a...

Poison message failure propagation is a mechanism that has been responsible for large scale failures in both telecommunications and IP networks: Some or all of the network elements have a software or protocol ‘bug’ that is activated on receipt of a certain network control/management message (the poison message). This activated ‘bug’ will cause the node to fail with some probability. If the netw...

Several North American species of Pogonomyrmex harvester ants exhibit group foraging, whereas South American species are exclusively solitary foragers. The composition of the secretions of the poison and Dufour glands in the South American species, Pogonomyrmex vermiculatus, were analyzed, and the secretions and their components were tested as trail pheromones in laboratory bioassays. The major...

Dee Jones is 35 years old, married, and the mother of three children, all younger than15 years of age. She had been healthy all of her life before she presented with a 2-week history of abdominal discomfort and anorexia. Evaluation revealed moderate jaundice, an enlarged liver, and abnormal liver function tests. An image of the abdomen showed a pancreatic mass and widespread metastatic disease ...

Gth August.?A Bungarus Fasciatus, nearly full-grown, was bittea by the same Cobra at 12-22 p.m., at about eight inches from the head. The snake was bitten twice; the Cobra took firm hold, and implanted the fangs deeply. At 2-30, when I left, there was no change; the Bungarus eeemed unaffected. The Bungarus died at 7-30 p.m. of the 7th, about 29 hours after being bitten. At 1 p.m. of the 7th, he...
