Exercise and Endogenous Opiates

The discovery of endogenous opiates in 1975 (1) generated considerable research concerning the effects of exercise on the release of these peptides, particularly on -endorphin, which represents the main focus of this chapter. Previous research considered changes in peripheral blood concentrations induced by different modes of physical activity, influences of training status on the secretion of ...

Endogenous opiates and stress-induced eating.

Maickel, G. K. W. Yim, Life Sci. 26, 2113 (1980)] and failed to observe their reported decrease ofTP eating after naloxone. We have also used greater numbers of TP trials with the same negative results [N. L. Ostrowski, N. Rowland, T. L. Foley, J. L. Nelson, L. D. Reid, PharmacQl. Biochem. Behav. 14, 549 (1981)]. In each case we measured the amount consumed, amount spilled, and duration of food...

Enkephalins and endorphins: the endogenous opiates.

The discovery of the opiate receptors in the central nervous system of man and subsequent identification of endogenous opiate-like ligands (enkephalins and endorphins) has provided a model for the analgesia, euphoria and addiction produced by the narcotics. In this article, the author reviews the background, biosynthesis and degradation, distribution, nociceptive transmission and analgesic effe...
