The change of endogenous opiate peptides and monoamines in cerebral tissue after cerebral ischemia / 临床神经病学杂志

ABSTRACT

Rats were used to establish an animal model of cerebral ischemia and the change of endogenous opiate peptides (LEK, ?-EP, DynA1-13) and monoamines (5-HT, 5-HIAA) levels in the ischemia cerebral tissue were measured. The main findings were as follows The levels of LEK reduced slightly in cerebral ischemia for 60 minutes, but the levels of DynA1-13 and 5-HIAA increased obviously in cerebral ischemia for 60 minutes. At the same time the levels of ?-EP and 5-HT decreased obviously. The results suggest that the endogenous opiate peptides and monomines play a possible role in the development of cerebral ischemic damage.
