Chemotherapeutic therapies for cancer are frequently associated with cytotoxic side effects that can be harmful to human health, including the development of intestinal mucositis (IM). It mostly affects the gastrointestinal tract, causing ulceration, inflammation, and the formation of lesions in the colon. Surprisingly, despite the frequency of IM, therapeutic choices remain restricted. In our search for new intestinal mucositis therapies, we wanted to see how Lentinan (LT), derived from Lentinus edodes, would fare in mouse models of intestinal mucositis. To create the intestinal mucositis model in mice, we gave them intra-peritoneal doses of 5-fluorouracil (5-FU) (50 mg/kg) and then tested the effects of Lentinan on intestinal mucositis. This examination required constant monitoring of several factors, such as body weight fluctuations, food consumption, and diarrhea. In addition, we measured the levels of certain inflammatory cytokines (Tumour Necrosis Factor-alpha (TNF-α), Interleukin-1 (IL-1), Interleukin-6 (IL-6), and Interleukin-10 (IL-10), looked at the expression of tight junction proteins (Zonula Occludens-1(ZO-1), Claudin-1), measured mucin-2 levels, and looked into changes in the gut flora. In the mouse model of intestinal mucositis, our findings showed that LT effectively reduced weight loss, increased food intake, and relieved diarrhea. Concurrently, we saw a decrease in the expression of inflammatory cytokines such as TNF-α, IL-1, and IL-6, as well as a considera...
