Methionine-enkephalin and leucine-enkephalin in human sympathoadrenal system and pheochromocytoma.
To elucidate the physiological and pathophysiological significance of methionine- and leucine-enkephalin (Met-and Leu-enkephalin, respectively) in human sympathoadrenal system, the contents of these peptides in normal human sympathetic nervous system, adrenal medulla, and pheochromocytomas were determined by specific radioimmunoassays combined with reverse-phase high-performance liquid chromato...
متن کاملSuggestive evidence for receptors for morphine and methionine-enkephalin on normal human blood T lymphocytes.
This study reports the in vitro influence of morphine, dextromoramide, levomoramide, and methionine-enkephalin upon normal human T blood lymphocytes by using the active and total rosette tests. Morphine and dextromoramide inhibited the percentage of active T rosettes. This effect was completely reversed in the presence of naloxone, their specific antagonist. The specificity was further demonstr...
متن کاملIn vitro release of [5-methionine]enkephalin and [5-leucine]-enkephalin from the rat globus pallidus.
Endogenous [5-methionine]enkephalin (Metenkephalin) and [5-leucine]enkephalin (Leu-enkephalin) are released from perfused slices of rat globus pallidus by increased K(+) in a Ca(2+)-dependent manner. Tissue perfused for 40 min contained only 26% of the Met-enkephalin and 44% of the Leu-enkephalin found in the freshly dissected tissue. After perfusion, the mean (+/-SEM) ratio (wt/wt) of Met-enke...
متن کاملThe human spinal cord: substance P and methionine-enkephalin immunoreactivity.
The distribution of substance P-like (SPLI) and methionine-enkephalin-like (MELI) immunoreactivity in the thoracic, lumbar, and sacral human spinal cord was studied in sections stained by the indirect antibody peroxidase-antiperoxidase method. The laminar distributions of SPLI and MELI were somewhat similar. Immunoreactive axons and terminal-like processes were found in the marginal zone and su...
