  • In the view of oriental medicine, the liver is the general of the army in its function of protecting against the enemy. So this concept is very closely associated to the immunological function. Its relations with immunological function are as follows. 1. The liver produces most of the proteins and converts them with hepatocytes, composes 80% in total reticuloendothelial system with Kuffer cells & endothelial cells and has typical structure of sinusoidal vessels closely related with the blood system. 2. The liver plays an important role in innate immunity with Kuffer cells as well as with the molecules that the liver produces, related to complementary systems. 3. In the embryonic period, the liver is associated with immune associated cell growth and their maturation. After birth, it is associated with removing old red blood cells and with systematically modulating immune system through hormone metabolism. 4. The liver controls the autoimmune disease resulting from immune complex by removing molecules like immune complex. 5. In the processing of blood 19A from the digestive system, the liver has an important role in protecting the body from unnecessary immune responses. 6. In the oriental medical view, liver plays a major role in the immune function by storing blood and dispersing stagnated hepatoqi with the help of the kidneys and spleen.

  • Cadmium (Cd) is a prevalent environmental contaminant that poses a potential hazard to the health of both humans and animals. In this study, biosynthesized selenium-enriched Lactobacillus plantarum and selenium nanoparticles (SeNPs) were developed and evaluated for their protective effects against Cd-induced hepatic injury in mice through oral administration for 4 weeks. Cadmium exposure resulted in severe impairment of liver function, as evidenced by increased levels of serum markers of liver injury and, oxidative stress and significant damage to liver tissue, and a notable decrease in the diversity of the intestinal microbiota. Oral administration of Se-enriched L. plantarum (LS) reduced cadmium accumulation in the liver by 49.5% and, restored other cadmium-induced damage markers to normal levels. A comparison of the effects with those of L. plantarum (L) and SeNPs isolated from LS revealed that LS could more effectively alleviate hepatic oxidative stress and reduce the intrahepatic inflammatory responses of the liver, further protecting against cadmium-induced liver injury. These findings suggest that the development of LS may be effective at protecting the liver and intestinal tract from cadmium-induced damage.

  • The cabbage extract of the research does not show cytotoxicity, and thus can be used safely. In an experiment performed on an animal model with liver injury induced by a drug (APAP), it could be seen that the cabbage extract exhibited the effects of protecting liver and improving liver function by effectively reducing AST and ALT which are liver injury markers, indicating that the cabbage extract is effective as a pharmaceutical composition for preventing or treating liver disease. In particular, the cabbage extract was effective in treating inflammation of the liver by reducing the expression of the inflammatory mediators iNOS and COX-2 and the proinflammatory cytokine IL-1β, which are involved in acute inflammatory reactions accompanying liver injury. In the research, an extract of cabbage heat-treated at a temperature of 100 to 150℃ had a better liver function-improving effect or anti-inflammatory effect than an extract of raw cabbage.

  • The liver, a multifunctional organ, plays a vital role in maintaining overall health and well-being by regulating metabolism, detoxification, nutrient storage, hormone balance, and immune function. Liver diseases, such as hepatitis, cirrhosis, fatty liver disease, and liver cancer, have significant clinical implications and remain a global health concern. This article reviews the therapeutic potential of silkworm larvae (Bombyx mori) and explores their underlying molecular mechanisms in protecting against liver diseases. Silkworm larvae are rich in proteins, vitamins, minerals, and n-3 fatty acids, making them a promising candidate for therapeutic applications. The anti-inflammatory mechanisms of silkworm larvae involve modulating the production of cytokine such as TNF-α and interleukins, inflammatory enzymes including cyclooxygenase-2 and macrophage polarization, thereby attenuating liver inflammation. Silkworm larvae also exhibit anti-oxidative effects by scavenging free radicals, reducing intracellular reactive oxygen species and enhancing the liver's antioxidant defense system. Moreover, silkworms have been reported to decrease the serum alcohol concentration and lipid accumulation. Understanding the therapeutic properties of silkworm larvae contributes to the development of innovative strategies for liver injury prevention and treatment. Further research is warranted to elucidate the precise signaling pathways involved in the anti-inflammatory and anti-oxidative effects of silkworm larvae, paving the way for potential therapeutic interventions in liver diseases.

  • Objectives : This experiment was conducted to verify the effects of some oriental herbs(Alny Cortex et Ramulus, Artemisiae Capillaris Herba, Aurantii Nobilis Pericarpium, Giseng Radix, Hoveniae Semen, Puerariae Flos, Puerariae Radix, and Xanthii Fructus) which have been used in the treatment of alcoholic diseases, on alcoholic metabolism, and on alcoholic liver damage. Methods : The effects of the herbs on the activities of alcohol dehydrogenase(ADH), aldehyde dehydrogenase(ALDH) were evaluated and their protective effects of liver function and cells from alcoholic damage were analysed. For the evaluation of the protective effects, the levels of glucose, triglyceride, BUN, AST, and ALT in serum of rats were measured. Results and Conclusions : It is concluded that Puerariae Radix interferes with the ADH activity directly, thereby reducing the toxicity of alcohol, resulting in enhancing alcohol-tolerance and protecting liver functions. Also Artemisiae Capillaris Herba interferes both ADH and ALDH activities. Isolation of the biologically active compounds from Puerariae Radix and its detailed characterization are matters for future research.

  • 최근 석류씨 기름은 항암효과를 포함하여 다양한 효과가 있는 것으로 확인되고 있다. 본 연구는 BALB/c 생쥐에 석류씨 기름을 처리한 후 사염화탄소를 주사하여 석류씨 기름이 간 독성에 어떤 영향을 미치는지 확인하기 위하여 올리브 기름만을 처리한 대조군, 사염화탄소만을 처리한 실험군1, 및 사염화탄소를 처리한 후 석류씨 기름을 구강투여한 실험군2로 나누어 24시간 후 혈액을 채취하여 혈청내 AST (aspartate aminotransferase, SGOT), ALT (alanine aminotransferase, SGPT), total protein, albumin, total bilirubin, direct bilirubin 및 alkaline phosphatase의 함량을 측정하였고 광학현미경과 투과전자현미경으로 조직의 변화를 관찰하였다. AST와 ALT는 대조군에서 각각 $88.70{\pm}14.90$$22.00{\pm}3.12IU/L$, 실험군 1에서 $1963.70{\pm}1212.90$$4495.40{\pm}2803.60IU/L$ 그리고 실험군2에서 $432.20{\pm}260.10$$692.30{\pm}433.10IU/L$이었으며 실험군2에서의 측정값은 실험군 1에 비해 유의한 차이를 보였다(P<0.005). 간조직을 관찰한 결과 사염화탄소를 처리한 실험군1에서는 문맥을 제외한 중심정맥 주위에서 간조직의 심한 응고성 괴사가 관찰되었고, 괴사조직 가장자리 주위로 지방변성을 확인할 수 있었다. 이에 비하여 석류씨 기름을 처리한 군에서 중심정맥 주위의 간실질 조직의 괴사가 실험군1에 비하여 현저히 줄어들었고, 간세포의 지방변성은 계속 관찰되었으나 용해소체의 감소와 미토콘드리아가 실험군1에 비해서 보존되어 있는 것으로 보아 석류씨 기름이 간보호에 효과가 있는 것으로 사료된다.

  • Objectives: Alcoholic fatty liver is a potentially pathologic condition which can progress to steatohepatitis, fibrosis, and cirrhosis. The objective of this study is to investigate the effects of Scutellaria Radix (SR) extract on the alcoholic fatty liver induced by long-term EtOH administration. Results: Male Sprague Dawley rats were used in this study. All animals were randomly divided into Normal group, treated with saline (n=10); EtOH group, treated with ethanol (n=10); EtOH+SR group, treated with ethanol+Scutellaria Radix extract (n=10). For oral administration of ethanol in EtOH and EtOH+SR group, the ethanol was dissolved in distilled water in concentrations of 25% (v/v). Throughout the experiment of 8 week, the rats were allowed free access to water and standard chow. Sample group were administrated by Scutellaria Radix extract daily for 8 weeks. Results: The levels of hepatic marker such as aspartate aminotransferase and alanine aminotransferase were altered. Histopathological changes such as ballooning, fatty and hydropic degeneration were reduced and the expression of tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) was significantly attenuated by Scutellaria Radix extract. Conclusions: These data suggest that Scutellaria Radix extract attenuated the alcoholic simple fatty liver by improving hepatic lipid metabolism via suppression of $TNF-{\alpha}$ protein. Scutellaria Radix could be effective in protecting the liver from alcoholic fatty liver.
