Objective : If the penetration ratio of the intestinal mucosa is increased, the toxic or unhealthy materials - which should not be absorbed into our bodies - will be come into our bodies. They cause a sort of anti-toxic response or confusion of the immune system, and ultimately bring various types of diseases. This syndrome is related "Poison in Excrement" or "Internal Damage(內傷發癍)" and Leaky Gut Syndrome, so I will study on the relationship between them. Method : Study on the relationship between Dae-Jang-Jung-gyeok and Leaky Gut Syndrome. Result : Korean doctors in ancient times called this syndrome "Poison in Excrement" or "Internal Damage(內傷發癍)" and treated it with "Dae-Jang-Jung-Gyeok(大腸正格)". Leaky Gut Syndrome is a sort of clinical lesion, which allows foreign and harmful toxins in and results in a disorder of the immune system due to the leaking intestinal mucosa. Conclusion : Based upon the analyses, Dae-Jang-Jung-Gyeok and Leaky Gut Syndrome are closely related. Therefore diseases caused by the Leaky Gut Syndrome might be expected to be cured by Dae-Jang-Jung-Gyeok. Particularly the use of treatments for self-immune diseases and allergic diseases such as atopyic dermatitis and articular rheumatism should be expected to reveal a new path of treatment for other disorders such as Leaky Gut Syndrome.

Chronic gut inflammation promotes the development of metabolic diseases such as obesity. There is growing evidence which suggests that dysbiosis in gut microbiota and metabolites disrupt the integrity of the intestinal barrier and significantly impact the level of inflammation in various tissues, including the liver and adipose tissues. Moreover, dietary sources are connected to the development of leaky gut syndrome through their interaction with the gut microbiota. This review examines the effects of these factors on intestinal microorganisms and the communication pathways between the gut-liver and gut-brain axis. The consumption of diets rich in fats and carbohydrates has been found to weaken the adherence of tight junction proteins in the gastrointestinal tract. Consequently, this allows endotoxins, such as lipopolysaccharides produced by detrimental bacteria, to permeate through portal veins, leading to metabolic endotoxemia and alterations in the gut microbiome composition with reduced production of metabolites, such as short-chain fatty acids. However, the precise correlation between gut microbiota and alternative sweeteners remains uncertain, necessitating further investigation. This study highlights the significance of exploring the impact of diet on gut microbiota and the underlying mechanisms in the gut-liver and gut-brain axis. Nevertheless, limited research on the gut-liver axis poses challenges in comprehending the intricate connections between diet and the gut-brain axis. This underscores the need for comprehensive studies to elucidate the intricate gut-brain mechanisms underlying intestinal health and microbiota.

Objectives The purpose of this study is to give an account of the effects of the Traditional Korean herbal medicine therapy which is based on the Sasang constitutional medicine on psoriasis Methods We diagnosed her as Soyangin(少陽人) based on her nature and emotion, physical chracteristics, symptoms. We thought Leaky Gut Syndrome is related to Soyangin Food Stagnation, stuffiness and fullness(食滯痞滿). So we applied Dokhwaljihwang-tang(獨活地黃湯) which is used to Soyangin Food Stagnation, stuffiness and fullness because her symptoms recurred as a result of Food Stagnation(食滯) after eating meat. The improvement of the skin condition was observed by Psoriasis Area and Severity Index (PASI) score Results Psoriasis patient who was treated with Soyangin Dokhwaljihwang-tang showed improvement in Psoriasis symptom. This case study describes the effectivenss on psoriasis symptoms by using Soyangin Dokhwaljihwang-tang. Conclusions The PASI score of the patient reduced from 10.8 to 1.2 after three months of treatment. According to the result, we concluded that Dokhwaljihwang-tang had a good effect on psoriasis.

Objectives: The aim of this study is to investigate anti-imflammatory and protective effect for intestinal epithelial cells with Atractylodes macrocephae (AM), a traditional Korean Herbal medicine and fermented Atractylodes macrocephae (FAM) with Lactobacillus plantarum. Methods: HCT-116 and Raw 264.7 cells were used in this study. Using NO assay, we measured lipopolysaccharide (LPS)-induced anti-inflammatory effect. We measured permeability of intestinal epithelial cells with transepithelial electrical resistance and horseradish peroxide flux assay. Water soluble tetrazolium salt assay was used to see cell proliferation. All the results were presented in mean and standard deviation. We used Student's t-test for analyzing significance of results. Results: In Raw 264.7 cells NO production decreased 22.4% with pre-treatment of AM and FAM, especially with FAM in high concentration. In HCT-116 cells LPS-induced intestinal permeability had a protective effect with both AM and FAM, which was also tend to be proportional to the concentration. Cell viability increased up to 135.52% after treatment of high concentration of FAM in HCT-116, while there was no significant change in Raw 264.7 cells with herb treatments. Conclusions: These results show evidence that AM, especially fermented ones, significantly reduced intestinal membrane permeability. They also had a protective effect as well as an anti-inflammation effect for HCT-116 and Raw 264.7 cells. This suggest that FAM may be a therapeutic agent for Leaky gut syndrome by reducing intestinal permeability.

This study was designed to examine influence of bacteria and herbal applications of Lonicerae Flos on the permeability of intestinal epithelial cells. The HCT-116 human intestinal cell was used as an in vivo model of "leaky gut". Dextran sodium sulphate (DSS) was used to induce an increase in the permeability of epithelial cell tight junctions. Probiotics including Lactobacillus acidophilus, Lactobacillus plantarum, Salomonella spp. and Staphylococcus aureus were used to evaluate bacterial influence on the intestinal epithelial cells. Herbal extract Lonicerae Flos was also assessed to find out what kind of effects it has when used alone or fermented with Lactobacillus plantarum. The permeability of intestinal cell lines was assessed using transepithelial electrical resistance (TEER) and horseradish peroxide (HRP) assessments. This data provides evidence for the probiotic benefits of intestinal permeability. The data also provides promising evidence of herbal effects on reducing intestinal permeability, especially when fermented with probiotics.

Objectives : The purpose of this study is to review the latest discussions on the mechanism of Itching. Methods : Articles that reviewed the mechanism of itching were searched from Pubmed (January 2016 to June 2021). In addition, review articles discussing the gastrointestinal tract and the mechanisms of pruritus were searched seperately. Results : The articles are classified into three categories. These categories are the classification according to the passage of time (acute, chronic), the immune factors involved (inflammatory, non-inflammatory), and the neurophysiological mechanism (pruritoceptive itching, neuropathic itching, neurogenic itching, psychogenic itching). In each category, the articles over the past five years are summarized and reviewed. Also, how the status of the gastrointestinal tract is reflected in itching was discussed in terms of leaky gut syndrome, neuro/gastrointestinal peptides, and gut microbiota. Conclusions : This review introduces the recently discussed mechanism of itching, and in particular, examines how the gastrointestinal tract is related to skin itching. Based on these considerations, it is expected that more diverse therapeutic approaches can be explored in the future.
