Moderate capsaicin-containing kochujang alleviates memory impairment through the gut-brain axis in rats with scopolamine-induced amnesia. Biomed Pharmacother 2024; 178:117091. [PMID: 39024840 DOI: 10.1016/j.biopha.2024.117091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 06/25/2024] [Accepted: 07/02/2024] [Indexed: 07/20/2024] Open
Abstract
This study investigated the efficacy and mechanism of traditionally made kochujang(TMK) with different capsaicin levels to alleviate memory impairment in rats with scopolamine-induced amnesia. Sprague-Dawley male rats were administered scopolamine (2 mg/kg bw/day) intraperitoneally to suppress the parasympathetic nervous system(PNS) and induce memory impairment. The rats were divided into four experimental groups, each consuming a diet containing 1 % kochujang in a 43-energy% high-fat diet(HFD) for 8 weeks. The TMK samples used for the study were categorized according to their capsaicin(CPS) content as follows: Low-CPS(0.5 mg%), medium-CPS(1.2 mg%), and high-CPS(1.7 mg%). In addition, factory-made kochujang (FMK; 1.1 mg% capsaicin) was also tested. The effects of kochujang were compared with the Control group(scopolamine), Positive-control(scopolamine+donepezil), and Normal-control(saline) fed HFD. Kochujang consumption reduced body weight and fat mass compared to the Control group. Compared to the Control, memory function measured using passive avoidance, water maze, and novel object recognition tests was enhanced in kochujang-fed rats, especially in the Medium-CPS group, similar to Positive-control. The Medium-CPS and Positive-control groups also exhibited inhibition of hippocampal cell death and increased cholesterol and triglyceride contents and mRNA expression of TNF-α and IL-1β in the brain tissue compared to the Control group. Additionally, TMK elevated short-chain fatty acid, particularly, butyrate concentration in the portal vein. Scopolamine disturbed large intestine cell morphology and gut microbiota composition, and kochujang improved them. Kochujang in the medium-CPS (1.2 mg%) had a more significant impact on the gut microbiota in the interaction analysis between gut microbiota and memory function. In conclusion, kochujang, especially with medium-CPS (1.2 mg%), is a potential dietary intervention to mitigate memory impairment and promote overall cognitive health through improving eubiosis, potentially linked to the gut-brain axis in PNS-suppressed rats.

Abstract
Colitis can significantly impact daily life. This study utilized DSS to induce acute colitis in mice and examined the regulatory effect of arabinogalactan (AG). The findings demonstrated that AG intake effectively alleviated the phenotype of DSS-induced colitis in mice and protected against small intestine damage. Furthermore, AG suppressed the secretion of pro-inflammatory factors TNF-α and IL-1β, while promoting the secretion of anti-inflammatory factor IL-10. It also inhibited the secretion of LPS in serum and MPO in colon tissue. Additionally, AG regulated the NF-κB/MAPK/PPARγ signaling pathway and inhibited the NLRP3 inflammasome signaling pathway, thereby ameliorating DSS-induced colitis inflammation in mice. AG also influenced the metabolism of short-chain fatty acids, particularly butyrate, in the intestinal tract of mice. Moreover, AG modulated and enhanced the composition of intestinal flora in mice with colitis, increasing the diversity of dominant flora and promoting the growth of beneficial bacteria. These results highlight the protective effects of arabinogalactan against colitis and its potential applications in the food industry.

Abstract
The prevalence of constipation, one of the common gastrointestinal (GI) diseases, has been gradually increasing. Gochujang, a traditional Korean fermented paste, has various microbiota and exerts diverse health beneficial effects. However, the ameliorative effect of Gochujang on constipation is unexplored. Seven-week-old ICR mice were divided into five groups: the normal group, the loperamide (LOP) group, the LOP + mosapride citrate (3 mg per kg BW, MOSA) treated group, the LOP + BMG Gochujang (2 g per kg BW) group, and the LOP + VMG Gochujang (2 g per kg BW) group. Gochujang alleviated constipation by increasing defecation frequency and water content in feces by reducing AQP3 mRNA expression. Additionally, Gochujang increased GI transit time and excitatory neurotransmitter levels and decreased inhibitory neurotransmitter levels. Moreover, Gochujang reduced mitogen-activated protein kinase (MAPK) activation and increased the c-Kit/SCF signaling pathway, suggesting that Gochujang regulates the enteric nervous system (ENS). Interestingly, BMG and VMG differently influenced the gut microbiota composition. Both Gochujang groups significantly decreased the Bacteroidetes and Firmicutes ratio compared to the LOP group. However, among Firmicutes genera, Acetatifactor was only reduced in BMG, and VMG only decreased Caproiciproducens and Acutalibacter. In summary, Gochujang effectively alleviated LOP-induced constipation outcomes regardless of their different microbial communities by ameliorating GI motility and changing the gut microbiota composition.

Microorganisms 2023; 11:microorganisms11040911. [PMID: 37110334 PMCID: PMC10141003 DOI: 10.3390/microorganisms11040911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 03/29/2023] [Accepted: 03/30/2023] [Indexed: 04/03/2023] Open
Abstract
Abnormal fat accumulation with gut microbiota dysbiosis results in hepatic inflammation by upregulating the release of lipopolysaccharide (LPS) and inflammatory cytokine. Gochujang, a traditional fermented condiment, has beneficial effects, such as anti-colonic inflammatory effects. However, Gochujang has been controversial because of its high salt content (the Korean Paradox). Thus, the present study aimed to investigate the preventative effects of Gochujang on hepatic inflammation and related gut microbiota through discussing the Korean Paradox. The mice were divided into groups including a normal diet (ND), high-fat diet (HD), HD with salt (SALT), HD with a high percentage of beneficial microbiota Gochujang (HBM), and HD with diverse beneficial microbiota Gochujang (DBM). Gochujang markedly reduced lipid accumulation, hepatic injury, and inflammation response. Furthermore, Gochujang attenuated protein expression involved in the JNK/IκB/NF-κB pathway. Additionally, Gochujang regulated the gut microbiota-derived LPS production and Firmicutes/Bacteroidetes ratio. Gochujang regulated the levels of gut microbiota such as Bacteroides, Muribaculum, Lactobacillus, and Enterorhabdus, which were correlated with hepatic inflammation. Salt did not have foregoing effects, meaning that the salt content in Gochujang did not affect its anti-inflammatory effect. In conclusion, Gochujang showed anti-hepatic inflammation effects via reduced lipid accumulation, hepatic injury, and inflammatory response together with reorganization of gut microbiota dysbiosis regardless of salt content and the difference of micro bacteria composition.

Abstract
High-fat and high-salt diets are risk factors for metabolic syndrome development. However, gochujang, which has a high salt content, possesses antiobesity properties in cell and animal models. We aimed to evaluate the effects of Sunchang traditional and modern factory produced gochujang on metabolic syndrome factors in high-fat diet (HFD)-induced obese mice. For 14 weeks, 4-week-old C57BL/6J male mice were separated into five groups and fed a normal diet (ND), a high-fat diet only (HD), a HD with salt (SALT), a HD with traditional Sunchang gochujang (TS), and HD with modern factory made Sunchang gochujang (FS). Compared to HD and SALT groups, the gochujang groups had lower body weight, blood leptin, and insulin levels with reduced Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) index and improved serum and liver lipid profiles. In addition, gochujang supplemented groups exhibited a significant reduction in mRNA expression of anabolic lipid metabolism related factors; PPARγ, CEBPα, and FABP4, and a significant increase in mRNA expression of energy expenditure-related factors; PPARα and CPT1. Protein expressions of SREBP1 were downregulated in the gochujang fed groups. TS and FS intakes improved obesity in HFD-induced obese mice. Compared to the gochujang groups, the SALT group did not exhibit any of those benefits suggesting that the high salt content of gochujang has different effects compared with added salt alone. Our findings provide evidence that gochujang could be a functional food to attenuate metabolic syndrome.

Abstract
Inflammatory bowel diseases, including Crohn's disease and ulcerative colitis, is a chronic relapsing gastrointestinal inflammatory disease mediated by dysregulated immune responses to resident intestinal microbiota. Current conventional approaches including aminosalicylates, corticosteroids, immunosuppressive agents, and biological therapies are focused on reducing intestinal inflammation besides inducing and maintaining disease remission, and managing complications. However, these therapies are not curative and are associated with various limitations, such as drug resistance, low responsiveness and adverse events. Recent accumulated evidence has revealed the involvement of mucin-degrading bacterium Akkermansia muciniphila (A. muciniphila) in the regulation of host barrier function and immune response, and how reduced intestinal colonisation of probiotic A. muciniphila can contribute to the process and development of inflammatory bowel diseases, suggesting that it may be a potential target and promising strategy for the therapy of inflammatory bowel disease. In this review, we summarise the current knowledge of the role of A. muciniphila in IBD, especially focusing on the related mechanisms, as well as the strategies based on supplementation with A. muciniphila, probiotics and prebiotics, natural diets, drugs, and herbs to promote its colonisation in the gut, and holds promise for A. muciniphila-targeted and -based therapies in the treatment of inflammatory bowel disease.

Protective effects of amoxicillin and probiotics on colon disorders in an experimental model of acute diverticulitis disease. Inflammopharmacology 2022; 30:2153-2165.

Abstract
AbstractAcute diverticulitis disease is associated with inflammation and infection in the colon diverticula and may lead to severe morbidity. This study aimed to evaluate and compare the protective effects of amoxicillin antibiotic, either alone or in combination with probiotics (Lactobacillus acidophilus and Bifidobacterium lactis), in a rat model of acute diverticulitis disease. Acute diverticulitis was induced, in albino rats, by adding 3% weight/volume of dextran sulfate sodium (DSS) to the rats’ drinking water; daily for 7 days, in addition to injecting lipopolysaccharide (LPS) enema (4 mg/kg). The impact of treatments was assessed by measuring the physiological and immunological parameters and evaluating colon macroscopic and microscopic lesions. The results showed that both treatments (especially probiotics with amoxicillin) alleviated the adverse effects of DSS and LPS. This was obvious through the modulation of the rats’ body weight and the colon weight-to-length ratio. Also, there was a significant (p < 0.001) decrease in the colon macroscopic lesion score. The pro-inflammatory cytokines [(TNF)-α, (IL)-1β, (IFN)-γ, and (IL)-18]; in the colon tissue; were significantly (p < 0.001) decreased. Also, both treatments significantly ameliorated the elevation of myeloperoxidase activity and C-reactive protein levels, in addition to improving the histopathological alterations in the colon tissue. In conclusion, amoxicillin and probiotics–amoxicillin were effective in preventing the development of experimentally induced acute diverticulitis, through their anti-inflammatory and immunomodulatory effects. Furthermore, this study has explored the role of probiotics in preventing DSS/LPS-induced acute diverticulitis, so it can be applied as a promising treatment option for acute diverticulitis disease.
