Naloxone-precipitated abstinence in mice, rats and gerbils acutely dependent on morphine.

K. Ramabadran
Life sciences
1983

Acute dependence on a single dose of morphine in mice, rats and gerbils was assessed by observing several signs of abstinence precipitated by various doses of naloxone, diprenorphine and Mr 2097. In… (More)

Tail immersion test for the evaluation of a nociceptive reaction in mice. Methodological considerations.

K. Ramabadran, Mylarrao Bansinath, Herman Turndorf, Margarita María Puig
Journal of pharmacological methods
1989

The effect of two commonly used methods to immobilize the animals, viz. tube restrainer and wrapping in a diaper (chux) on the tail flick latency in immersion test, was evaluated in mice using a… (More)

Effects of the benzomorphan kappa-opiate, MR 2266 and its (+) enantiomer MR 2267, on thermonociceptive reactions in different strains of mice.

Mylarrao Bansinath, K. Ramabadran, Herman Turndorf, Margarita María Puig
Neuroscience letters
1990

The effects of the benzomorphan kappa opiate MR 2266 and its dextro enantiomer MR 2267 were assessed on thermonociception in Swiss Webster, C57BL/6, BALB/c and DBA/2 strains of mice. In the hot plate… (More)

Effects of N-methylnaloxone and N-methylnaltrexone on nociception and precipitated abstinence in mice.

K. Ramabadran
Life sciences
1982

Subcutaneous administrations of naloxone and naltrexone have already been shown to enhance nociceptive reactions in mice. The present study was undertaken to examine the effects of N-methyl-naloxone… (More)

Opioid peptides from milk as a possible cause of sudden infant death syndrome.

K. Ramabadran, Mylarrao Bansinath
Medical hypotheses
1988

Milk from breast or baby formula is the exclusive source of nutrition for newborn infants. Short chain opioid peptides such as beta-casomorphins have been isolated from breast milk as well as baby… (More)

Mylarrao Bansinath, K. Ramabadran, Herman Turndorf, Margarita María Puig
Physiology & behavior
1991

The effects of the benzomorphan kappa-opiate antagonist MR 2266 and its dextro enantiomer MR 2267 were assessed on thermonociception in male Swiss Webster mice. Experimental diabetes was induced by… (More)

An analysis of precipitated withdrawal in rats acutely dependent on morphine.

K. Ramabadran
Japanese journal of pharmacology
1985

Acute dependence on a single dose of morphine was assessed in Wistar rats by observing the frequencies of occurrence of several signs of withdrawal precipitated by naloxone, diprenorphine, Mr2097,… (More)

Strain differences in the hyperalgesic effect of a novel kappa receptor agonist, U-50488H in mice.

K. Ramabadran
European journal of pharmacology
1984

The administration of a kappa agonist, U- 50488H produced reduction in jumping latencies in the hot plate test in Swiss and CBA strains of mice but not in CXBH , CXBK and C57BL strains. The… (More)
