This study was carried out to investigate the effect of LAB (Lactic acid bacteria: Lactobacillus acidophilus, Bifidobacterium bifidum and Streptococcus thermophilus) on detoxication of damaged liver in carbon tetrachloride ($CCl_4$) and ethanol (25%)-treated rats. Rats had been daily (twice a day) pre-treated with saline (0.5 ml/kg: untreated group), $CCl_4$ (0.5 ml/kg: other groups) for 6 days. At seventh day, after treating rat with $CCl_4$ and then, mixture of LAB ($10^{11}$/0.5 ml: LAB group), saline (0.5 ml/kg: untreated group, $CCl_4$ group), and biphenyl dimethyl dicarboxylate (DDB) (50 mg/kg: DDB group) were treated orally with $CCl_4$ for 8 days. Ethanol is treated as the same manner instead of $CCl_4$. To investigate the hepatoprotective effect, rats treated with $CCl_4$ and ethanol were analyzed with serum GOT and GPT level. The GOT and GPT levels of LAB group was lower than the level of $CCl_4$ and DDB group. Especially, compared with data of $CCl_4$ group, GPT activity showed statistically significant result in the significance level of p < 0.05. The LAB group treated with ethanol also showed lower level of GOT and GPT than the other control groups treated with ethanol. The triglyceride level of serum decreased more in a group treated special materials (DDB and LAB group) than ethanol group. As well, the effect of LAB on the antifatigue has been investigated. The animals (10/group) were divided into 4 groups (untreated group, Carrier group, Red-ginseng group, LAB group). Each group was given carrier (0.9 mg/0.2 ml), red ginseng extract (200 mg/kg), and mixture of LAB ($10^{11}$/0.2 ml). Special materials were given for three weeks. After finishing treating through oral, horizontal wire test, rotarod test, and forced swimming test were performed. The time of resistance to fatigue of the group, fed with mixture of LAB, was longer than the time when mice treated with red-ginseng that the effect was already revealed. The result of this study revealed that LAB could decrease hepatocelluar injury compared with rats treated orally with $CCl_4$ and ethanol, and could also decrease fatigue.

The effect of methanol extract from Agaricus blazei Murill on the hepatotoxicity was investigated $CCl_4$ is one of the oldest and most widely used toxins for the induction of hepatic damages and fibrosis in experimental animals. In this study, male Sprague-Dawley(SD) rats were randomly divided into 6 groups of the control(C), $CCl_4(T),\;CCl_4$ and high fat group(TL) with matching sub-groups of Agaricus blazei Murill extract-fed groups of CA, TA and TLA. Methanol extracts of Agaricus blazei Murill were fed 50 mg/kg B.W daily via drinking water. A 1.2 mL of $CCl_4/kg$ body weight was administered by oral intubation twice a week for total of six times. The levels of total-cholesterol, TG, LDL and LDL-phospholipids were elevated by $CCl_4$ treatment as compared to the control(C). However, Agaricus blazei Murill methanol extract feeding in the group of TA and TLA significantly(p<0.05) decreased TG by 53.1 % and 17.9% compared to the internal control of T and TL, respectively. Triglyceride of TL was increased by 3.33 times(p<0.05) compared to the control(C) with $CCl_4$ and high fat administration from 3.78 mg/g to 12.60 mg/g liver. The extract(CA) also reduced kidney weight compared to the control(C). With the administration of high fat and $CCl_4$(TLA), the extract reduced the organ weight of both liver and kidney and further, significantly reduced TG, total cholesterol and GTP activity. Hepatoprotective effects of Agaricus blazei Murill on GOT, GPT, AP and LDH activities were enhanced by the extract feeding. Electronmicrograph showed that $CCl_4$ deteriorated the structure of cytoplasmic matrix with its uneven distribution. However, the extract reconstituted the damaged cytoplasm and stimulated mitochondriogenesis. The above results suggest that Agaricus blazei Murill may have a possible protective effect against chemically induced liver damage and further help to reduce the symptoms of fatty liver.

Quercetin은 항산화 및 항염증 활성이 잘 알려져 있으나, 건선 피부염 조절에 대한 효능 연구는 거의 보고된 것이 없어, in vitro 건선 피부염 시험 모델인 TNF-α/IL-17A 유도 HaCaT 세포주를 이용해 quercetin에 의한 건선 피부염 개선 효과를 규명하였다. 먼저, TNF-α에 의해 활성화된 HaCaT 세포주에 quercetin을 처리한 결과, IL-1α, IL-1β, IL-6 등 염증성 사이토카인 발현이 TNF-α 처리군 대비 각각 49.1±7.14, 42.8±8.16, 34.5±2.52% 억제되었다. Th17세포 및 수지상세포 등 면역세포를 염증 반응 부위로 유인하는 케모카인 IL-8 및 CCL20의 mRNA 발현량 또한 TNF-α 처리군 대비 38.4±5.83, 52.9±4.59% 감소하였다. TNF-α 자극에 의해 건선피부에서 비특이적으로 증가되는 케라틴 단백질 KRT6A 및 KRT16 발현뿐만 아니라, IκBα 및 STAT3 단백질의 인산화 또한 quercetin에 의해 유의적으로 억제되었다. 또 다른 건선 유발 사이토카인으로 알려진 IL-17A로 HaCaT 세포주를 자극한 후 quercetin에 의한 영향을 관찰한 결과, IκBα mRNA 발현은 55.8±5.28% 감소하였고, STAT3 인산화는 36.3±6.81% 하향 조절되었다. 마지막으로 TNF-α/IL-17A를 동시 자극한 HaCaT 세포주에 quercetin을 처리한 결과, IL-1α, IL-1β, IL-6, TNF-α, CCL20 유전자 발현이 모두 억제되는 것을 확인하였다. 이를 통해 quercetin은 기존 항산화, 항염증 활성뿐만 아니라 건선 피부염 개선에 활성을 갖는 소재임을 확인할 수 있었다.

Objectives: Psoriasis is a common chronic inflammatory skin disease characterized by keratinocyte hyperproliferation and an excessive inflammatory response. Agents that can attenuate keratinocyte hyperproliferation and excessive inflammatory responses are considered potentially useful for the treatment of psoriasis. Daehwangmokdanpitang (DHMDPT) exhibits a broad range of bioactivities, including anti-proliferative and anti-inflammatory effects. This study aims to evaluate the anti-psoriatic potential of DHMDPT in vitro. Methods: HaCaT keratinocytes were stimulated with a mixture of IL-17A, IL-22, oncostatin M, IL-1α, and TNF-α (M5) to establish an in vitro psoriatic keratinocyte model. Cell viability was measured using the MTT assay. Quantitative real-time PCR (qRT-PCR) was performed to measure the mRNA levels of the hyperproliferative marker gene keratin 6 (KRT6) and inflammatory factors such as IL-6, TNF-α, and IL-23A. Additionally, chemokines including CCL5, CCL2, CCL20, and CXCL1 were measured by qRT-PCR. Results: DHMDPT attenuated M5-induced hyperproliferation, as indicated by a reduction in KRT6 expression in HaCaT keratinocytes. M5 stimulation significantly upregulated the mRNA levels of IL-6, TNF-α, and IL-23A. However, DHMDPT treatment attenuated the upregulation of IL-6 but not TNF-α or IL-23A. Additionally, DHMDPT inhibited the expression of CCL5, CCL2, and CXCL1, but not CCL20. Conclusion: DHMDPT effectively attenuated the M5-induced proliferation and inflammatory response in HaCaT keratinocytes. Therefore, DHMDPT could be an attractive candidate for future development as an anti-psoriatic agent.

Atopic dermatitis (AD) is a chronic, recurrent inflammatory skin disease that is associated with Th2 cell-mediated allergy. The process that leads to infiltration of inflammatory cells into an AD lesion is remarkably dependent on various chemokines, especially TARC (thymus and activation-regulated chemokine/CCL17) and MDC (macrophage-derived chemokine/CCL22). Serum levels of these chemokines are over-expressed in AD patients. Citrus unshiu, which is known as Satsuma mandarin, has anti-oxidative, anti-inflammation, and anti-microviral activity. Therefore, we investigated the effect of EtOH extract of premature C. unshiu on AD. We did this using a DNCB-induced AD mouse model. We also tried to confirm an inhibitory effect for premature C. unshiu on the expression of inflammatory chemokines in IFN-${\gamma}$ and TNF-${\alpha}$ stimulated HaCaT human keratinocytes. We found that extract of premature C. unshiu reduced DNCB-induced symptoms such as hyperkeratosis, increased skin thickness, and infiltrated mast cells, in our AD-like animal model. The extract decreased levels of IFN-${\gamma}$ and IL-4 in ConA-stimulated splenocytes isolated from DNCB-treated mice. Also, extract of premature C. unshiu inhibited mRNA expression and protein production of TARC and MDC through the inhibition of STAT1 phosphorylation. These results suggest that C. unshiu has anti-atopic activity by regulating inflammatory chemokines such as TARC and MDC.

Background: Complementary and alternative medicine has been highly appreciated as a supportive regimen for classical treatment strategies. Here we offer a nutrition-based adjuvant therapy for liver fibrosis, a major risk factor for cirrhosis and hepatocellular carcinoma. Aim of the study: To evaluate the possible hepatoprotective effects of Jerusalem artichoke tubers (JAT) in combination with interferon and ribavirin. Materials and Methods: Twelve groups of rats were administered JAT, interferon and ribavirin either separately or in combination from day one of $CCL_4$ administration until the end of the study. Animals were killed after 8 weeks of $CCL_4$-induced hepatotoxicity. Results: Hepatocytes from rats treated with triple combination of interferon, ribavirin, and JAT showed more less normal architecture compared to $CCL_4$-treated rats. We also detected significantly higher hepatic protein expression levels of p53, BAX and transforming growth factor-${\beta}$ (TGF-${\beta}$) in the $CCL_4$-intoxicated group compared to normal controls, as evidenced by immunohistochemical staining and western blotting analyses. Addition of JAT as a supportive regimen improved response to ribavirin and interferon and effectively participated in retaining normal histopathological and biochemical criteria and significantly lowered protein expression of p53, BAX, and TGF-${\beta}$. Conclusions: We suggest that addition of JAT as a supportive r egimen to interferon and ribavirin effectively potentiates their anti-fibrotic effects.

Atopic dermatitis (AD) is an inflammatory skin disease commonly characterized by infiltration of inflammatory cells into skin lesions. Keratinocytes produce many chemokines that are involved in the pathogenesis of skin disorders. In particular, macrophage-derived chemokine (MDC/CCL22) and thymus and activationregulated chemokine (TARC/CCL17) are Th2-type cytokines. Serum MDC and TARC levels are increased in AD patients. In this study, we investigated the anti-inflammatory effect and mechanism of action of the active fraction from Prunus yedoensis bark. We evaluated their inhibitory effects on the AD-like inflammatory markers (MDC and TARC) and JAK-STAT pathway (STAT1) in HaCaT keratinocytes. The EtOAc fraction of the crude extract (80% EtOH) and the E5 sub-fraction potently inhibited the induction of MDC and TARC mRNA and protein at 50 ${\mu}g$/mL in HaCaT cells. In addition, the E5 sub-fraction inhibited the phosphorylation of STAT1 protein associated with IFN-$\gamma$ signaling transduction in a dose-dependent manner. Thus, P. yedoensis may have antiatopic activity by suppressing the inflammatory chemokines (MDC and TARC).

Oxidative stress and its consequent lipid peroxidation exert harmful effects, which have been currently involved in the generation of carbon tetrachloride (CCl₄)-induced fibrosis(cirrhosis). In this study, it was investigated whether dried extract of 田螺(Concha Cipangopaludinae; CC) has liver functional improvement, antioxidative and antifibrotic effect in rats those were induced liver fibrosis by CCl₄ administration. The female Sprague-Dawley rats were divided into 3 groups(Normal, AC, AC-CC) and were observed in 6 weeks. Except for normal group, liver fibrosis(cirrhosis) in rats were developed by CCl₄ administration(0.8 ㎖/rat/week). And the rats were treated with prepared CC(p. o. 2 ㎖/day/rat). At the time of sacrifice, the liver, kidney and spleen were weighed and the ratio of organ weight/body weight was calculated. The MDA, hyp and biochemical parameters(AST, ALT, ALP, t-bili) were measured in sera and liver tissue of rats. The strong yellow color of urine was observed in all CCl₄-treated group compared with normal group, but jaundice didn't appear in CCl₄-treated group. The mortality of CCl₄-treated group is very low(<13%) during 6 weeks of observation time. The ratio of liver/body as well as the weight of liver in CCl₄-treated rats significantly increased compared with that in normal group(p<0.001). The level of clinical parameters in sera of all liver fibrosis(cirrhosis) developed rats were significantly higher than that of normal group(p<0.001-0.05). Especially the value of BUN, ALP, t-bilirubin in AC-CC group showed 20.9%, 19.6%, 47.9% lower than that in AC group. The content of hyp in CCl₄-treated rats was significantly higher than normal group(p<0.001～<0.05), and showed 12.2% lower value in the AC-CC group than AC group(p<0.05). The production of lipid peroxidation(MDA) in sera and liver tissue significantly increased under the fibrotic(cirrhotic) condition(p<0.001～<0.05). Especially the MDA value of AC-CC group in sera significantly 46.5% decreased compared with that of AC group(p<0.05), and the MDA value of AC-CC in liver tissue showed 21.4% lower than that of AC group. Concha Cipangopaludinae can be improved hepatic function, and maybe have effect of liver protection, antioxidation and antifibrosis.
