Inhibitory effect of Jangkanghwan (Korean traditional food) on experimental ulcerative colitis in mice

다국어 초록 (Multilingual Abstract)

Jangkanghwan (JKH) can delay weight loss in mice, promote weight gain during recovery, and reduce colonic shortening and colon weight. In addition, the murine disease activity index was controlled after treatment using JKH. It can reduce the content of pro‐inflammatory factors in serum and expression in tissues, such as interleukin (IL)‐6, IL‐1β, tumor necrosis factor‐α, interferon‐γ, cyclooxygenase‐2, and nuclear factor kappa‐B; in contrast, the content and expression of IL‐10 and the inhibitor of nuclear factor kappa‐B kinase‐α in the serum and tissues were increased. The mRNA expression of the colitis characteristic biomarker monocyte chemoattractant protein‐1 and macrophage inflammatory protein‐3α were reduced in colon tissues. Using next‐generation sequencing technology, the Bacteroidetes phylum in the JKH group decreased, while the Firmicutes phylum increased, and the number of beneficial bacteria—Bifidobacteriaceae, Lactobacillaceae, and Akkermansiaceae—increased.
JKH is a mixture of colonic healthy foods composed of Atractylodes macrocephala koidzumi, radish leaves, Viscum album var. coloratum, dried Zingiber officinale Roscoe, etc. According to UPLC‐Q‐TOF MS analysis, JKH consists mainly of 17 active substances, such as pheophorbide A, nabumetone alcohol, dehydrocostus lactone, plantamajoside, kaempferol 3, 7‐dirhamnoside, quercetin 3‐D‐glucuronide, and viscumneoside III. We investigated the preventive effects of JKH on dextran sulfate sodium (DSS)‐induced ulcerative colitis in a murine model and found that JKH can reduce the damage in mice caused by DSS treatment.
As a traditional Korean health food, JKH consists of natural anti‐inflammatory ingredients that can reduce the level of inflammation in mice caused by DSS treatment. JKH can balance the destruction of intestinal microbial environment and reduce the number and the colonization of harmful microorganisms in the intestine. JKH can reduce colonic mucosal damage and avoid clinical symptoms of ulcerative colitis.
