  • Background: Small particles increase airway inflammation upon reaching the alveoli. Here, we investigated the protective or therapeutic effects of Salvia plebeia R. Br. (SP_R) extracts on airway inflammation. Methods and Results: To investigate the anti-inflammatory activity of SP_R extracts, we measured their inhibitory effect on the production of reactive oxygen species (ROS) expression of inflammatory mediators, and immune cell infiltration in MH-S alveolar macrophage cells and in the ambient particulate matter (APM)-exposed airway inflammation mice model. The SP_R extracts inhibited the production of ROS and expression of IL-4, IL-10, IL-15, and IL-17A mRNA in APM-stimulated MH-S cells. Oral administration of SP_R extracts suppressed APM-induced inflammatory symptoms, such as high alveolar wall thickness, excess collagen fibers, decreased mRNA expression of chemokines (Ccr9, Ccl5, Ccr3), inflammatory cytokines (IL-15, TNF-${\alpha}$), and IL-4 Th2 cytokine in the lung. The SP_R extracts also inhibited ROS production, granulocyte ($CD11b^+Gr-1^+$) infiltration, IL-17A, TNF-${\alpha}$, macrophage inflammatory protein (Mip-2), and chemokine (C-X-C motif) ligand 1 (Cxcl-1) production in the airway. The specific compounds in the SR-R extracts that mediate the anti-inflammatory effects were identified. Conclusions: In this study, SP_R extracts effectively inhibited airway inflammatory responses, such as ROS production and granulocyte infiltration into the airway, by regulating the expression of chemokines and inflammatory cytokines.

  • In order to investigate anti-inflammatory, anti-allergic and anti-obesity activities of Samchulkunbi-tang (SCT; Shen zhu jian pi-tang) water and 70% ethanol (EtOH) extracts, in vitro inhibitory activities against nitric oxide (NO), prostaglandin $E_2$ $PGE_2$), interleukin (IL)-6 and tumor necrosis factor (TNF)-${\alpha}$ production in lipopolysaccharide-stimulated RAW 264.7 cells, and macrophage-derived chemokine (MDC/CCL22) and regulated on activation of normal T-cell-expressed and -secreted (RANTES/CCL5) production in TNF-${\alpha}$/interferon-${\gamma}$-stimulated HaCaT and BEAS-2B cells as well as glycerol-3-phosphate dehydrogenase (GPDH) activity and leptin production in 3T3-L1 cells were determined. A HPLC was used for quantification of the seven marker components (albiflorin, paeoniflorin, liquiritin, naringin, hesperidin, poncirin and glycyrrhizin) of SCT water and 70% EtOH extracts. SCT showed inhibitory effects against MDC and RANTES production in HaCaT cells, as well as RANTES production in BEAS-2B cells. In addition, SCT reduced not only NO, $PGE_2$, IL-6 and TNF-${\alpha}$ production in RAW 264.7 cells, but also GPDH activity and leptin production in 3T3-L1 cells. Furthermore, the biological activities and the contents of six compounds (except paeoniflorin) were higher in 70% EtOH extract than water extract. These results suggest that SCT has anti-inflammatory, anti-allergic and anti-obesity activities. These efficacies of 70% EtOH extract are relatively higher than that of water extract.

  • The major components were isolated from the n-hexane, EtOAc and BuOH extract of Galla Rhois(Rhus Javanica Linne). Their structures were characterized as syringic acid, gallic acid methylester, protocatechuic acid, gallic acid and 1, 2, 3, 4, $6-penta-O-galloyl-{\beta}-D-glucose$. This study was carried out to investigate the biological activities of isolated compounds. Five compounds were tested for hepatoprotective effects on CCl4-induced cytotoxicity in primary cultured rat hepatocytes and antioxidative effect on Ferric-Thiocyanate method and TBA method. As a result, isolated five compounds showed stronger antioxidative activity than tocopherol, and the antioxidative activity of gallic acid methylester, protocatechuic acid and syringic acid were similar to that of BHA on Ferric-Thiocyanate method. Specially 1, 2, 3, 4, $6-penta-O-galloyl-{\beta}-D-glucose$ showed stronger effect of lipid-peroxidation inhibition than BHA. Gallic acid appeared stronger inhibitory effect of malondialdehyde on TBA method. Hepatoprotective effect of 1, 2, 3, 4, $6-penta-O-galloyl -{\beta}-D-glucose$ was similar or even higher than that of glycyrrhizin on primary cultured rat hepatocyte cytotoxicity.

  • $Nokyangbotang^{TM}$ (NYBT) is a kind of powerful food for health and have been drunk at a oral dose of 80 ml (99.5 mg) three times per day: It has not been well studied about the anti-fatigue and hepatoprotective activity. In this experiments, we evaluated pathophysiologically the effect of NYBT on swimming time in mouse and hepatoprotective activity in rats intoxicated with carbon-tetrachloride. NYBT was nontoxic in orally acute toxicity test ($LD_{50}$, 320 ml/60 kg): a nontoxic food in more four times of one-shoot dosage (80 ml) to human. Weight-loaded forced swimming test was carried out to measure the swimming time of mice with a 4% load of body weight in plastic cylinder (diameter $10{\;}cm{\;}{\times}{\;}height{\;}20{\;}cm$) on water bath at $25^{\circ}C$, and the anti-fatigue activity represented the ratio of swimming time of experimental group to that of control group. NYBT had dose-dependent anti-fatigue activity Mice administered NYBT at a dose of 320 ml/60 kg once daily for 5 days could swim about two times more than control. Hepatoprotective activities of NYBT were examined by the determination of malonedialdehyde (MDA) and pathological survey in liver and liver function test of rat intoxicated with $CCl_4$ at i.m. dose of 2 ml/kg once daily for 7days. NYBT decreased dose-dependently thiobarbituric acid reactive substance: Oral administration of NYBT at a dose of 20 ml/60 kg was $38.51{\;}{\pm}{\;}3.02$ nmol MDA/g of tissue, that of 80 ml/60 kg was $33.76{\;}{\pm}{\;} 1.84$ nmol MDA/g of tissue, and that of 320 ml/60 kg was $32.87{\;}{\pm}{\;}1.90$ nmol MDA/g of tissue as compared with control group ($43.61{\;}{\pm}{\;}2.85$ nmol MDA/g of tissue). All rats administered NYBT at a dose of 320 ml/60 kg were survival as compared with 40% survival of control animals, and GPT activity of rats administered NYBT at a dose of 80 ml/60 kg was decreased as compared with control. In histopathological survey, NYBT improved slightly the fatty changes of hepatocytes around centrilobular area. These results suggest that NYBT has anti-fatigue and hepatoprotective activity in rats and mice.

  • The $2{\nu}_{C=0}$ + amide III combination band spectrum of acetamide (AA) was obtained in very dilute solutions of AA+lanthanide shift reagents (LSR) in carbon tetrachloride over the range of $15^{\circ}$ to $45^{\circ}C$. It was found that only 1 : 1 AA-LSR complex is formed by the interaction between carbonyl oxygen of AA and central metal ion(Ln(Ⅲ)) in LSR. The thermodynamic parameters for Ln(III)${\cdot}$O=C bond were determined by computer analysis of concentration and temperature dependent spectra. ${\Delta}H^{\circ}$ for the coordination of AA to Eu$(dpm)_3$, Yb$(dpm)_3$, and Pr$(dpm)_3$ have been found to be -39.1, -28.4, and -25.5 kJ/mol, respectively. It has shown that this type of ion-dipole interaction is more than twice stronger compared to the dipole-dipole interaction in the amide linkage, and largely depending on the steric hindrence effect by the bulky dpm groups around central metal ion (Ln(III)) rather than the ionic potential effect of central metal ion itself.

  • Objective: Rutin, also called vitamin P, is a flavonoids from plants. Previous studies have indicated that rutin can alleviate the injury of tissues and cells by inhibiting oxidative stress and ameliorating inflammation. There is no report on the protective effects of rutin on goat rumen epithelial cells (GRECs) at present. Hence, we investigated whether rutin can alleviate lipopolysaccharide (LPS)-induced damage in GRECs. Methods: GRECs were cultured in basal medium or basal medium containing 1 ㎍/mL LPS, or 1 ㎍/mL LPS and 20 ㎍/mL rutin. Six replicates were performed for each group. After 3-h culture, the GRECs were harvested to detect the relevant parameters. Results: Rutin significantly enhanced the cell activity (p<0.05) and transepithelial electrical resistance (TEER) (p<0.01) and significantly reduced the apoptosis rate (p<0.05) of LPS-induced GRECs. Rutin significantly increased superoxide dismutase, glutathione peroxidase, and catalase activity (p<0.01) and significantly decreased lactate dehydrogenase activity and reactive oxygen species and malondialdehyde (MDA) levels in LPS-induced GRECs (p<0.01). The mRNA and protein levels of interleukin 6 (IL-6), IL-1β, and C-X-C motif chemokine ligand 8 (CXCL8) and the mRNA level of tumor necrosis factor-α (TNF-α) and chemokine C-C motif ligand 5 (CCL5) were significantly increased in LPS-induced GRECs (p<0.05 or p<0.01), while rutin supplementation significantly decreased the mRNA and protein levels of IL-6, TNF-α, and CXCL8 in LPS-induced GRECs (p<0.05 or p<0.01). The mRNA level of toll-like receptor 2 (TLR2), and the mRNA and protein levels of TLR4 and nuclear factor κB (NF-κB) was significantly improved in LPS-induced GRECs (p<0.05 or p<0.01), whereas rutin supplementation could significantly reduce the mRNA and protein levels of TLR4 (p<0.05 or p<0.01). In addition, rutin had a tendency of decreasing the protein levels of CXCL6, NF-κB, and inhibitor of nuclear factor kappa-B alpha (0.05

  • The present study was done with two aims. First, to evaluate the radiographic measurements of liver volumes in normal and hepatomegaly dogs induced by carbon tetrachloride. Second, to investigate quantitative tissue echo pattern by ultrasonography. Gray level histogram of the normal liver and the kidney were estimated with carbon tetra-chloride intoxication. In normal, r-square for liver volume to body weight was 0.93372, and this showed direct linear regression. Gray level histograms of the normal liver and the kidney were $19.150{\pm}2.490$(mean${\pm}$SD) and $13.175{\pm}2.686$(mean${\pm}$SD) respectively(p < 0.01). Liver parenchymal echogenicity was more hyperechogenic than kidney cortex echogenicity. Liver/Kidney ratio was $1.504{\pm}0.313$ and it can be used relative comparison of liver and kidney parenchymal echogenicity. In carbon-tetrachloride($CCl_4$) intoxication, changes of liver volume appeared to increase up to 24 hours after administration (p < 0.05), and decreased gradually to normal level after 2~5 days. Gray level histogram of liver parenchyma decreased up to 24hours (p < 0.01) after intoxication and then gradually increased to normal level. But that of kidney cortex had no significant change. Liver/Kidney ratio also decreased by 2 days(p < 0.01) and then gradually increased to normal level. On histopathologic features of hepatic tissues in carbon tetrachloride intoxication, both coagulative necrosis of hepatic cell and hemorrhage of centrilobular & midzonal area were identified. Conclusively, plain radiography is a useful diagnostic method for evaluating liver volume in mild hepatomegaly. Especially, it is considered that an adequate numerical processing of the liver length, depth and thoracic width and depth measurement would be helpful. Using gray level histogram, ultrasonographic evaluation was useful objective methods in early diagnosis of diffuse hepatic disease.

  • Intracellular ions which have a major role in cellular function have been reported to affect repair of radiation damage. Recently it has been reported that ouabain sensitizes A549 tumor cellls but not CCL-120 normal cells to radiation. Ouabain inhibits the $Na^+-K^+$-pump rapidly thus it increases intracellular Na concentration, Vanadate which is distributed extensively in almost all living organisms is known to be a $Na^+-K^+$-ATPase inhibitors, This study was performed to see any change in radiosensitivity of tumor cell by vanadate and any role of $Na^+-K^+$ATPase in radiosensitization. Experiments have been carried out by pretreatment with vanadate in human cell line(A549, JMG) and mouse cell line(L1210, spleen). For the cell survival MTT assay was performed for A549 and JMC cells and frypan blue dye exclusion test for L120, and spleen cells. Measurements of $Na^+-K^+$-ATPase activity in control, vanadate treated cell, radiation treated cell (9 Gy for A549 and JMG, 2 Gy for L1201, spleen), and combined $10^{-6}M$ vanadate and radiation treated cells were done. The results were summerized as fellows. 1. L1210 cell was most radiosensitive, and spleen cell and JMG cell were intermediate, and A549 cell was least radiosensitive. 2. Mininum or no cytotoxicity was seen with vanadate below concentration of $10^{-6}M$. 3. In A549 cells there was a little change in radiosensitivity with treatment of vanadate. However radiation sensitization was shown in low dose level of radiation i. e. 2- Gy. In JMG cells no change in radiosensitivity was noted. Both L1210 and spleen cell had radiosensitization but change was greater in tumor cell. 4. $Na^+-K^+$-ATPase activity was inhibited significantly in tumor cell by treatment of vanadate. 5. Radiaiton itself inhibited $Na^+-K^+$-ATPase activity of tumor cell with high $Na^+-K^+$-ATPase concention. Increase in radiosensitivity by vanadate was closely associated with orginal $Na^+-K^+$-ATPase contents. From the above results vanadate had little cytotoxicity and it sensitized tumor cells to radiation. Inhibitory effect of vanadate on $Na^+-K^+$-ATPase activity might be one of the contributing factors for radiosensitization to tumor cells which has greater enzyme activity than that of normal cell. It was suggested vanadate could be used as a potential radiosensitizer for tumor cells.

  • High resolution transmission electron microscopic observations on the $Hg_{1-x}\;Tl_{x}\;Ba_{2}(Ca_{0.86}\;Sr_{0.14})_{2}\;Cu_{3}\;O_{8+\delta}$(x=0.00, 0.25, 0.50, 0.75) were carried out using side-entry type TEM working at 300 kV. The TEM samples are prepared by powder method. The pellets are crushed in agatar motar and suspended in $CCl_4$, solution and scooped in holely carbon microgrid. The 1223 structures are observed in all samples with [010] zone axis. Except x=0.25 sample, the lattice parameter a and c tend to decrease as the thallium contents are increased ranging from 0.3936 nm to 0.3713 nm for a, and from 1.6131 nm to 1.5138 nm for c parameter. Those of x=0.25 sample are reduced too much, 0.3785 nm for a, 1.5375 nm for c. The sample with x=0.25 shows the intergrowth of 1223 and 1234 structure with the ratio of 19 to 1. As the thallium content increases, the structures become more stable without having any defect. The samples are damaged by electron beam irradiation during the observation, however the structure can endure longer as the thallium contents are increased.

  • This study was conducted to investigate the biological activities of polysaccharide extracted from the fruit body and cultured mycelia of Phellinus linteus IY001. All fractions were extracted by hot water, in the next, Fr. I, Fr. II, Fr. III and Fr. IV were polysaccharide obtained by ethanol precipitation or ultrafiltration. The highest antitumor activity against sarcoma 180 in ICR mice was observed in Fr. III and Fr. IV at the level 85%, but the antitumor activity had no connection with their anticomplementary activity in vitro, it might probably be due to extraction of hot water. All fractions promoted the production of nitric oxide and $TNF-{\alpha}$ in macrophage, addition of Fr. I and Fr. II resulted in production of nitric oxide$3(5.9{\sim}37.6\;{\mu}M)$ and of the $TNF-{\alpha}$ production($8,696.2{\sim}9,420pg/ml)$. All fractions inhibited the lipid peroxidation induced by $AsA/Fe^{2+}$, $ADP/NADPH/Fe^{3+}\;and\;CCl_4/NADPH$ in rat liver microsomes, and Fr. III showed the electron donating ability stronger than tocopherol in assay system using DPPH. From these results, it is suggested that all fractions contain immunoregulatory components which may protect cellular materials from the oxidative damages by their radical scavenging activities.
