Objectives: In our study, we aimed to (1) create a peritoneal metastasis (PM) model in nude mice, administer intraperitoneal chemotherapy using the peritoneal infusion pump we developed in this model, and (2) compare the efficacy of intraperitoneal chemotherapy using various drugs at different temperatures.
Methods: The peritoneal metastasis model was established in nude mice using the CC531 colon carcinoma cell line. Models with peritoneal metastasis (PM) were randomized into four groups of seven animals each: Group 1, control group (n=7); Group 2, normothermic intraperitoneal chemotherapy (NIPEC) with mitomycin C(MMC) (n=7); Group 3, hyperthermic intraperitoneal chemotherapy (HIPEC) with mitomycin C (n=7), and Group 4, NIPEC with 5-fluorouracil (5-FU).
Results: Tumor development was achieved in all animals. While the tumor burden decreased significantly in the treatment Group 3 (p=0.034), no significant difference was found in the other groups. In the PM mouse model, hyperthermic intraperitoneal administration of MMC had the highest tumoricidal effect.
Conclusions: Our PM model provided a good opportunity to examine the efficacy of HIPEC and intraperitoneal infusion pump (IPIP). In future studies, we plan to evaluate efficacies of different drugs in the PM models we have created.

Acute or chronic liver damage can result in Hepatic Encephalopathy (HE), a potentially fatal neuropsychiatric condition that leads to cerebral and neurological alterations. Dapagliflozin (DAPA), an orally active Sodium/Glucose cotransporter 2 inhibitor with long duration of action. The study aim was to evaluate the potential protective impact of DAPA against HE caused by Thioacetamide (TAA) in rats.

Aim: Chronic small-intestinal mucositis (CIM) is a severe gastrointestinal complication that has limited treatment options. This study investigated the potential therapeutic effects of Daikenchuto (DKT), a traditional medicine, on mitigating methotrexate (MTX)-induced CIM in rats.
Methods: Male Sprague-Dawley rats were assigned to four groups: control, MTX, DKT-MTX, and DKT.

Background: Intraperitoneal (IP) chemotherapy (IPC), including hyperthermic intraperitoneal chemotherapy (HIPEC), has emerged as a promising approach to control peritoneal metastases in gastrointestinal (GI) cancers. However, the safety profile and toxicity spectrum of IPC remain incompletely understood. This study aimed to evaluate the incidence of hematologic and biochemical adverse reactions following surgery with or without IPC and to compare the toxicity profiles of normothermic IPC and HIPEC.

Background: Obesity is associated with hormonal imbalance, increased oxidative stress, and inflammation in the testis. These conditions adversely affect sperm quality, leading to impaired male fertility. Therefore, therapeutic interventions to counteract the adverse effects of obesity are crucial.

Objectives: To investigate the therapeutic mechanism of 2,6-dimethoxy-1,4-benzoquinone (DMQ) for alleviating dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice.
Methods: Eighteen male C57BL/6J mice were equally randomized into control group, DSS group and DMQ treatment group. In DSS and DMQ groups, the mice were treated with DSS in drinking water to induce UC, and received intraperitoneal injections of sterile PBS or DMQ (20 mg/kg) during modeling.
