Abstract:
The present study deals with the histochemistry of intramural plexus in stomach, duodenum, ileum, caecum, proximal colon, distal colon and rectum of normal adult guinea pig, including the reaction of Mg~(++)-ATPase, Ca~(++)-ATPase, CCO, SDH, G6PDH, carbohydrate, protein, nucleic acid and lipid in the enteric neurons. The reactions of all the enzymes mentioned above are observed under the light microscope and estimated semiquantitatively, among which, Mg~(++)-ATPase and Ca~(++)-ATPase are measured quantitatively with microphotometer (Leitz MPV II). Both results of light microscope, and microphotometer were analysed statistically. It was found that the above mentioned enzyme activities in the enteric neurons, suggesting that the neurons carry out active metabolism with these concerned enzymes. There were significant differences in some enzyme activities between myenteric plexus and submucous plexus, the former showed higher activity in SDH, while the latter in LDH, G6PDH, and two kinds of ATPase. It is suggested that there are some differences in. the major metabolic manner of carbohydrate, energy metabolism and functional activity between, two plexus. Besides, there were marked difference in enzyme activities among myenteric plexus of different part of digestive tract, the highest activity was showed in duodenum and proximal colon, the lowest was in caecum. These results indicate that enteric neurons differ greatly in functional state, but whether or not the variation of enzyme activities is related with the different types of neurons is unknown.
