Abstract

To identify, the effects of acua-acupuncture of Bletillae rhizoma extract on the duodenal ulcer induced by HCl-aspirin in rats, the changes of histological profiles, number of mucous-producing goblet cells (PAS-positive cells), and morphology and/or number of chole-cystokinin (CCK)-8 and serotonin-immunoreactive (IR) cells in the gastrointestinal tract were observed after acua-acupuncture of Bletillae rhizoma extract on Ganshu locus ($BL_{14}$). Samples were collected at 1, 3 and 5 days after treatment. Histologically, very severe injury, atrophy of villus, necrosis of epithelial cell and hemorrhage, to the duodenal mucosa including epithelium were observed in HCl-aspirin administrated control groups, and these injuries were increased with time intervals. But in acua-acupuncture groups and nontreated normal groups, no gross lesion of ulcer was demonstrated and histologically minor injury to the apex of villas epithelium was observed. Compared to the PAS-positive cells of the control groups, those of the acua-acupuncture groups were increased. Severe degranulation of CCK-8- and serotonin-IR cells were observed in the control groups but these phenomena seldom occur in the acua-acupuncture groups. Serotonin-IR cells were significantly decreased in control groups but increased in the acua-acupuncture groups compared to control groups. However, these degranulation of IR cells of the aqua-acupuncture groups were less severe than those of normal groups, and number of serotonin-IR cells were lower than those of normal groups but these phenomena were decreased with time intervals and in 5 days after treatment, they were observed like those of normal groups. These result indicated that acua-acupuncture of Bletillae rhizoma extract would be accelerated the healing of the duodenal ulcer but the functional mechanisms were unknown.
