The regional distribution and relative frequency of endocrine cells in the GIT of the snakehead, Channa(Oph icephalus) argus were studied immunohistochemically. Five kinds of endocrine cells and one kind of nerve cell were identified in this study. A few numbers of secretin-immunoreactive cells were restricted to the cardia and fundus of the stomach. Moti-lin- and GRP-immunoreactive cells were rare in the epithelium of the distal and proximal intestines. PYY-immunoreactive cells were found in a few number in the pyloric caeca and were rare in the distal intestine. Substance P-immunoreactive cells were distributed relatively numerous from the fundus to the distal intetsine. Also, their nerve cells were detected in occurrence in the lamina propria in the distal intestine. No neurotensin-, met-Enk- and GIP-immunoreactive cells were found in the GIT of the snakehead.
