Groundwater arsenic (As) has affected millions of people globally distributed over 20 countries. In parts of West Bengal (India) and Bangladesh alone, over 100 million people are at risk, but supply of As-free water is grossly inadequate. Attempts to remove As by using orthodox medicines have mostly been unsuccessful. A potentized homeopathic remedy,(More)
We investigated whether the interoceptive discriminative stimulus (IDS) arising from ethanol withdrawal was related to decreased activity of the gamma-aminobutyric acid (GABA) system by determining whether the sensitivity of rats to the GABA antagonists was altered by chronic treatment with ethanol. Rats were trained to obtain food reward by responding on(More)
The present experiment was designed to determine whether disulfiram produced an interoceptive discriminative stimulus (IDS) in rats similar to that exhibited by the anxiogenic drug pentylenetetrazol (PTZ). Rats were trained to discriminate PTZ (20 mg/kg IP) from saline, according to an FR10 schedule of food reinforcement. After training criteria had been(More)
Rats were trained with food reinforcement to discriminate the anxiogenic drug pentylenetetrazol (PTZ, 20 mg/kg) from saline in a two-lever-choice task. In Experiment 1, ethanol, 8.25% w/v was given by gavage (7/day) for 4 days, with doses titrated to maintain moderate intoxication. After termination of ethanol, the rats exhibited mild overt signs of(More)
