  • To develop Allium victorialis var. platyphyllum (Liliaceae) for an available functional food, pharmacological experiments on the extracts of this plant were undertaken in the rat treated with streptozotocin, poloxamer-407 and $CCl_4$. The two MeOH extracts were obtained from the leaves and the bulbs, respectively. The three agents, streptozotocin, poloxamer-407 and $CCl_4$, were treated to induce diabetes mellitus, hyperlipidemia and hepatic injury, respectively. Treatment with the leaf extract lowered blood glucose by 24.9% at 200 mg/kg (p.o.) in the STZ-treated rat and prohibited the increase of body weight, water consumption and food intake. This exσact also significantly decreased not only thε plasma cholesterol and triglyceride in the poloxamer-407-treated rat by 35.3% but also serum ALT by 49.0%. The potency was found by overall estimation on the experimental results as followings: 200 mg/kg leaf extract> 200 mg/kg bulb extract> 100 mg/kg leaf exσact> 100 mg/kg bulb extract. These results suggested that this plant might have the availability for a functional food. It was also suggested that the leaves are more effective than the bulbs for the functional vegetable, especially in hyperlipidemia and hepatic injury.

  • The present study was performed to determine the protective effect of G009 on liver damage induced bv ethanol $CCl_4$ and thioacetamide in rats. In acute fatty liver animal model induced by ethanol, triglyceride accumulation was markedly decreased to the normal control level by 25 mg/kg G009 treatment. In addition, G009 significantly reduced serum ALT and AST levels in $CCl_4$-induced acute hepatitis animals. Treatment of G009 to the acute hepatitis rats induced by thioacetamide resulted in a dose dependent reduction of serum ALT level as well as AST level up to the normal control level. These protective effects of G009 were confirmed by histological examinations of the liver. These results suggested that G009 could be effective for the protection from the liver damage induced by ethanol, $CCl_4$and thioacetamide.

  • The objective of this study was to examine the biochemical parameters of hepatic function such as serum level of ALT (alanine aminotransferase), AST (aspartate aminotransferase), ALP (alkaline phosphatase), LDH (lactate dehydrogenase), and content of TG (triglyceride) and cholesterol, and tissue immunological changes of the $CCl_4$-treated rats with administration of the mixed sample extract (MSE). The liver weight in $CCl_4$-administered experimental control group (EC) was slightly higher than that of normal control (NC) group. Hepatic damage parameters (ALT, AST, ALP, LDH & TG) in serum of the EC group were significantly higher than those in serum of the NC and silymarin-treated positive control (PC) group. On the other hand, these hepatic damage parameters of MSE-treated experimental (E1 & E2) groups were significantly lower than those of EC group. The number of WBC, neutrophils, lymphocytes and platelets, and the contents of hemoglobin, and hematocrit in EC group were significantly higher than those of NC group. However, the number of WBC and lymphocytes in E1 and E2 groups were significantly lower than those of EC group. Also, the collagen developmental areas in the liver of NC and PC groups by hepatic immuno-histological findings were found slightly positive. Whereas, hepatic fibrous developmental tissue of EC group was strongly positive brown color band, those of E1 & E2 groups were decreased. Therefore, it was concluded that the induction of hepatic fibrous tissue activation had a preventive effect of MSE against the $CCl_4$-induced hepatic damage in rats. However, further study is needed in this filed.

  • Intestinal barrier dysfunction always accompanies cirrhosis in patients with advanced liver disease and is an important contributor facilitating bacterial translocation (BT), which has been involved in the pathogenesis of cirrhosis and its complications. Several studies have demonstrated the protective effect of Vitamin D on intestinal barrier function. However, severe cholestasis leads to vitamin D depletion. This study was designed to test whether vitamin D therapy improves intestinal dysfunction in cirrhosis. Rats were subcutaneously injected with 50% sterile $CCl_4$ (a mixture of pure $CCl_4$ and olive oil, 0.3 mL/100 g) twice a week for 6 weeks. Next, $1,25(OH)_2D_3$ ($0.5{\mu}g/100g$) and the vehicle were administered simultaneously with $CCl_4$ to compare the extent of intestinal histologic damage, tight junction protein expression, intestinal barrier function, BT, intestinal proliferation, apoptosis, and enterocyte turnover. Intestinal heme oxygenase-1 (HO-1) expression and oxidative stress were also assessed. We found that vitamin D could maintain intestinal epithelial proliferation and turnover, inhibit intestinal epithelial apoptosis, alleviate structural damage, and prevent BT and intestinal barrier dysfunction. These were achieved partly through restoration of HO-1 and inhibition of oxidative stress. Taken together, our results suggest that vitamin D ameliorated intestinal epithelial turnover and improved the integrity and function of intestinal barrier in $CCl_4$-induced liver cirrhotic rats. HO-1 signaling activation was involved in these above beneficial effects.

  • A 3-year-old, 5.6 kg, castrated, male, British short hair cat presented with subtle weight-bearing lameness of the right hindlimb when walking suddenly after rest. On physical examination, the patient experienced pain when the right stifle joint was hyperextended. There was no clinical improvement of lameness or pain of the right hindlimb, despite the administration of analgesic drugs for one week. During diagnostic arthroscopy of right stifle, mild synovitis and cranial cruciate ligament (CCL) impingement on osteophyte of the intercondylar notch (ICN) was observed. Computed tomography was applied to determine an accurate surgical plan. Arthroscopy-assisted notchplasty, including removal of the osteophyte, was performed using chisel and arthroscopic burr. At 4 weeks postoperatively, the frequency of subtle weight-bearing lameness of the right hindlimb was significantly reduced. At 6 months postoperatively, the patient exhibited normal ambulation without recurrence of lameness. Impingement of CCL may cause subtle lameness and pain. Arthroscopy can be a good diagnostic tool for early-stage CCL disease. Notchplasty can be recommended for osteophyte-induced CCL disease.

  • Background: This study was conducted to determine the anti-inflammatory effect of astaxanthin, on atopic dermatitis. Methods: Changes in mouse body weight, lymph node weight, and the degree of improvement in symptoms were measured to determine the inflammatory response. Real-time reverse transcription-polymerase chain reaction tests were performed to determine the degree of expression of inflammation-related cytokines (IL-31 and IL-33 and chemokines such as CCL17 and CCL22), and western blot analysis was performed to evaluate the expression of inflammation-related factors (iNOS, COX-2, and NF-kB signaling molecules p-IkBα, p50, p-65 and pSTAT3). Results: The degree of symptoms significantly improved in the PA+AX group. Lymph node weight in the PA+AX group was lower than the PA group. Inflammatory cytokines (IL-31, IL-33, and inflammatory chemokines such as CCL17 and CCL22) were significantly reduced in the PA+AX group compared with the PA group. The expression of inflammatory genes (iNOS, COX-2, NF-kB and signaling molecules (p-IkBα, p50, p65, and p-STAT 3) was lower in the PA+AX group compared with the PA group. Conclusion: Astaxanthin may modulate the inflammatory response in a mouse model of atopic dermatitis and has an anti-inflammatory effect.

  • This study was conducted to investigate the effect of methanol extract of Allomyrina dichotoma larva (MEAL) on carbon tetrachloride $(CCl_4)-induced$ hepatotoxicity in mice. ICR mice were divided into 5 groups [Vehicle control, $CCl_4\;(10{\mu}g/g)$ alone, $CCl_4$ plus a low dose $(50{\mu}g/g)$ of MEAL, $CCl_4$ plus a high dose $(100{\mu}g/g)$ of MEAL]. Silymarin $(2{\mu}g/g)$ was used as the reference in the experiment. Administration of MEAL tended to decrease the serum alanine transaminase (ALT) activity induced by $CCl_4$ treatment in mice. Hepatic concentration of thiobarbituric acid-reactive substances (TBARS) in a high-dose group of diet decreased to the level of silymarin-treated group. Hepatic activity of glutathione S-transferase in MEAL-treated group was lower than that of $CCl_4-treated$ group. Serum concentration of bilirubin was significantly increased by $CCl_4$ treatment, but MEAL or silymarin recovered the level. These results suggest that MEAL may exert the protective effect against $CCl_4-induced$ hepatotoxicity in mice. However, more intensive studies would be needed to elucidate the protective mechanism of the beetle on hepatotoxicity of mice.

  • The protective effects of a powder mixed with solid-cultured and liquid-cultured Lentinus edodes mycelia (2 : 1, w/w) (designate LED) with different doses of carbon tetrachloride ($CCl_4$) on induced hepatotoxicity in male Sprague-Dawley (SD) rats was investigated. The rats were divided into seven groups (6 rats/group) and the following substances were administered orally to each group: Vehicle (0.2 ml distilled water), Control (0.2 ml distilled water), LED (LED 100, 200, 300 and 400 mg/kg BW in 0.2 ml distilled water), and Silymarin (200 mg/Kg BW in 0.2 ml distilled water). After two weeks of daily administration, all groups except for the Vehiclegroup were subjected to abdominal injection with $CCl_4$ ($CCl_4$ : corn oil, 1 : 1 v/v; 0.5 ml/kg BW). One day later, blood and liver samples were collected to analyze biomarkers. All LED treatments elevated hepatic superoxide dismutase (SOD), catalase and glutathione peroxidase (GSH peroxidase) activities, and reduced thiobarbituric reactive substances (TBARS), tumor necrosis factor-$\alpha$ (TNF-$\alpha$), interleukin-$1{\beta}$ (IL-$1{\beta}$) and interleukin-6 (IL-6), resulting in the reduction of glutamate-oxalate transaminase (GOT), glutamate-pyruvate transaminase (GPT) and lactic acid dehydrogenase (LDH) activities in plasma. These results indicate that LED effectively protected SD rat hepatotoxicity induced by $CCl_4$ through its antioxidative activity and reduction of some cytokines. The highest efficacy was found in LED 200 mg/kg BW, showing potential as a useful material for protection from hepatotoxicity in humans.

  • This study was performed to observe the effect of Keughachukeo-tang(KH) extract on the hepatocellular carcinogenesis and acute liver damage induced by Diethylnitrosamine(DENA) and $CCl_4$ in Rats. Experimental groups were divided into four; normal group(Nor), acute liver damage and hepatocellular cancer inducing control group(Con), KH extract 350㎎/㎏/day(KHA), and 700㎎/㎏/day(KHB) administered groups to Con. The results obtained are as follows: The body weight increased in KHA and KHB than Con from 7th week to the 8th week. The activities of Alanine aminotransferase(ALT) were the most increased in the Con among experimental group. The activities of aspartate aminotransferase(AST), alkaline phosphatase(ALP), and lactacte dehydrogenase(LDH) were significantly decreased(p$<$0.05) in the KHA and KHB compared with Con. Alpha fetoprotein(AFP) were the most increased in the Con among experimental groups. The activities of superoxide dismutase(SOD) were the most increased in the Con among experimental groups. The activities of catalase were significantly increased(p$<$0.05) in the KHA and KHB compared with Con. The results of light microscopical observation, a number of hepatocytes were damaged in the Con compared with Nor and KH extract administerd groups. The number of hepatic p53 positive cells was reduced in the KH extract administered groups compared with Con. These results suggest that administration of KH extract suppress or retard on the Hepatocellular Carcinogenesis and acute liver damage induced by DENA and $CCl_4$ in Rats.

  • To examine the effect of overdosed functional food in liver-injured patients, we tried to investigate the dose effect of Allium sativum L. (also called garlic) extract on rats with CCl4-induced liver damage, by comparatively examinating the hepatic function of each group. 42 male Sprague-Dawley rats were selected and divided equally (n=7) into normal, control, positive control, and three experimental subgroups (E1, E2 and E3), respectively. For each kg of body weight, hepatic injury was induced by intraperitoneal administration of $0.5\;m{\ell}$ (0.20 g/kg/day) $CCl_4$, which was diluted in equal amount of olive oil, once a day on every other day for total 5 times. Hot water extraction was performed using domestically cultivated organic garlics, and the obtained extract was injected by sonde, once daily during 4 weeks, to each experimental subgroups by different dosage of 0.35 g/kg(E1), 0.70 g/kg(E2), 1.40 g/kg(E3), respectively. Results showed that the injection of garlic extract positively influenced the physiological activation which lowered the oxidative stress, changed the toxicity, and functionally improved the hepatic condition. Comparing the dose effect between the three experimental subgroups (E1, E2, E3), results of the maximal-dosed subgroup (E3) showed less significance compared with the lower-dosed subgroups(E1 and E2), which seems to resulted from the (increased) toxicity of garlic.
