Methionine-enkephalin and vasopressin in SHR: effects of dehydration

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1986
Enkephalins are found in the posterior pituitary, can alter vasopressin secretion, and have greater pressor effects in spontaneously hypertensive rats (SHR) than in Wistar-Kyoto (WKY) rats. Measurement of the plasma methionine-enkephalin concentration (PMet-Enk) has provided equivocal results in humans and has not been reported in rats.

Pharmacodynamics and Biophasic Drug Levels of Methionine Enkephalin

Pharmaceutical Research, 1991
Methionine enkephalin (Met-E) is a naturally occurring pentapeptide. It appears to mediate pain perception by blocking CNS pathways. Using rabbits, a log dose relationship was obtained between Met-E-induced dilation of the pupil (mydriasis) and constant intravenous infusion dose rates (14, 20, 28, 37, 56, 73, and 129 micrograms/min/kg).

Self-administration of methionine enkephalin into the nucleus accumbens

Pharmacology Biochemistry and Behavior, 1984
Microinfusions of the endogenous opiate neurohumor, methionine enkephalin, into the nucleus accumbens initiated a reinforcing stimulus in a dose-related manner. The reinforcing nature of this intracranial self-administration was evaluated with intermittent schedules of reinforcement and a two-lever discrimination procedure.

Methionine Enkephalin: Immunomodulator in Normal Volunteers (in Vivo)

1986
The enkephalin, methionine enkephalin (met-enkephalin) was originally discovered to be one of the endogenous ligands for morphine receptors (Hughes et al., 1975; Simontov and Snyder, 1976). However, Plotnikoff et al., (1976) discovered anti-depressant, anti-anxiety, and anti-convulsant effects of the enkephalins, identifying a much broader spectrum of ...

Conformational analysis of Methionine-Enkephalin and some analogs

Biochemical and Biophysical Research Communications, 1977
Abstract Conformational energy calculations on Methionine-Enkephalin and on several of its analogues indicate that the calculated lowest energy conformation of the native enkephalin may not be the conformer which interacts at the opioid active site.
