Abstract

The aim of the present study was to observe the effect of electroacupuncture (EA) on the gastric interstitial cells of Cajal (ICCs) in a rat model of diabetic gastroparesis (DGP). The gastric tissues were collected from 75 rats, which had been divided into three equal groups (n=25/group): Blank, model and EA. Hematoxylin and eosin and immunohistochemical staining were used to observe the cellular morphology and distribution of c‑kit‑positive gastric ICCs; light microscopy was used to count the number of ICCs; and electron microscopy was used to observe the ultrastructure of the rat ICCs. Compared with the model group, the gastromucosal glandular and smooth muscle cells of the EA group were more regularly arranged, with fewer vacuoles; there was an increased cellular gap and the vacuolar degeneration on the gastric walls was mild. Image analysis showed that the blank group exhibited the greatest number of c‑kit‑positive ICCs, and the number of c‑kit‑positive ICCs in the blank group was significantly different from that in the model and EA groups (P<0.01): Blank group > EA group > model group. In conclusion, DGP rats exhibited a reduced number of gastric ICCs, altered ultrastructural morphology and a reduced number of cell organelles, particularly mitochondria, compared with the blank group. EA may help to reverse the various pathological changes of gastric ICCs in rat models of DGP.
