[Study of treating experimental ulcerative colitis of spleen deficiency type with "guben yichang tablet" in guinea pigs].

Guinea pigs were perfused with the extract of senna (20%). 3 days later glacial acetic acid (5%) was given intra-anally so as to replicate the animal model of Spleen Deficiency (SD) and ulcerative colitis which is the disease of Western medicine combined with the Syndrome in TCM. The model animals showed the symptoms of SD such as loose stool, anorexia, wasting, aversion of cold, laziness and loss of hair luster and the symptoms of ulcerative colitis such as abdominal distension and mucous bloody stool. The colonic lesion were observed by eyes that the mucosa were edematous, congestive with ulcerative foci. The pathological examinations showed edema and congestion in submucous layers; large amount of inflammatory cell infiltration; and the scaling and ulcer formation of epithelium mucosae. The above-mentioned symptoms and pathological changes were the same as SD and ulcerative colitis in clinical practice. The new medicine "Guben Yichang Tablet" against ulcerative colitis was given to guinea pigs for 7 days could abate their symptoms, increase their body weights and decrease the size of colonic ulcer and edema.
