Embodiment Construction

[0015] 1. Chlamydia murine has anti-ulcerative colitis effect

[0016] (1) Growth of Chlamydia murine (CM) in the intestinal tract of C57BL / 6J wild-type mice (Table 1)

[0017] Table 1. Growth of CM in the intestine of wild-type mice (log10 )

[0018]

[0019] Note: ND means not detected

[0020] After Chlamydia murine infects C57BL / 6J wild-type mice by intragastric administration, the anus test was used to detect the growth of the intestinal lingloplasma. The results of IFA showed that the growth of Chlamydia in the intestines of wild-type mice was relatively stable. The role of anti-ulcerative colitis lays the groundwork.

[0021] (2) Chlamydia murine (CM) inhibited DSS-induced weight loss in C57BL / 6J wild-type mice ( figure 1 )

[0022] Wild-type murine Chlamydia (G13.32.1) was intragastrically infected (intragastric infection, i.g.) C57BL / 6J wild-type mice were given 3.5% DSS drinking water at 29 days after infection, and continued for 5 days. The results showed t...

Abstract

The present invention shows by experiments that mouse Chlamydia (Chlamydia muridarum, CM) can antagonize the wild-type mouse ulcerative colitis induced by dextran sulfate sodium (Dextran Sulfate Sodium, DSS), suggesting that CM has anti-ulcerative colitis It can be used to prepare anti-ulcerative colitis drugs.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and specifically relates to the application of murine chlamydia in the preparation of anti-ulcerative colitis medicine. Background technique [0002] Inflammatory bowel disease (Inflammatory Bowel Disease, IBD) is a common chronic inflammatory disease of the digestive system. Its clinical symptoms mainly include abdominal pain, diarrhea, and blood in the stool, and extraintestinal clinical manifestations such as skin, joints, eyes, bones, and liver and bile ducts often occur. The pathogenesis of IBD is complex, with multiple stages of pathogenesis, unclear etiology, easy recurrence, easy cancer and difficult to cure, so it is listed by the World Health Organization as one of the modern intractable diseases. Epidemiological surveys found that the incidence of the disease has been increasing year by year in recent years, which seriously endangers people's health and quality of life. Although ...
