$Pyunkang-tang^{(R)}$ is a kind of herbal medicine and has been used for the treatment of atopy and allergic disease in humans over forty years. The purpose of this study was to evaluate the hematological, biochemical, and protein and lipid electrophoresis profiles after the oral administration of $Pyunkang-tang^{(R)}$ in healthy dogs. Fifteen clinically healthy beagle dogs were selected and orally administered either 33 ml of $Pyunkang-tang^{(R)}$ (group I, n = 5), 16.5 ml of $Pyunkang-tang^{(R)}$ (group II, n = 5), or 33 ml of distilled water (group III, n = 5) 3 times a day for 4 weeks. The results of the hematological, serum biochemical, and urine analysis did not differ significantly among the 3 groups. The oral administration of $Pyunkang-tang^{(R)}$ for 4 weeks was associated with significant changes in the serum globulin levels and an elevation in the high-density lipoprotein (HDL) concentrations in groups I and II (p < 0.05), compared to group III. The ${\alpha}1-globulin$ and ${\gamma}-globulin$ levels were significantly increased in group I, and the ${\alpha}1-globulin$ and ${\beta}-globulin$ levels were significantly increased in group II. The ${\alpha}2-globulin$ levels were significantly decreased in both groups. During the short-term evaluation of $Pyunkang-tang^{(R)}$ administration, we did not detect any specific adverse effects in the dogs. However, further evaluation of the safety and efficacy of $Pyunkang-tang^{(R)}$ for the treatment of atopic disease in dogs is needed.

This study aimed to evaluate the anti-asthmatic effects of Samjajihwang-tang (SJT) using OVA-induced asthmatic mice model. Asthmatic mice model was conducted by repeated challenge of OVA using C57BL/6 mice. Each group was treated with distilled water, SJT (400 mg/kg and 200 mg/kg) extract or cyclosporin A (10 mg/kg) for the later 8 weeks, Penh (plethysmography and enhanced pause), immune cells subpopulation, eotaxin, IL-5, TNF-${\alpha}$, Anti-OVA-lgE in BALF (bronchoalveolar lavage), and lung tissue was analyzed, No cytotoxicity of SJT was shown on hFCs (human fibroblast cells). Administration of SJT significantly decreased Penh levels comparing to control group. SJT treatment significantly ameliorated the increase of total cells number and eosinophil including of immune cell subpopulation of $CD3^+/CD69^+$, $CCR3^+$, $B220^+/CD22^+$, $B220^+/CD45^+$, and $B220^+/lgE^+$ cells in BALF comparing to control group. Eotaxin, IL-5, TNF-${\alpha}$, and Anti-OVA-lgE level in BALF were significantly decreased by SJT treatment too. Histopathological finding verified the improvement of infiltration of inflammatory cells and collagen tissue in the SJT groups comparing to control group. These results strongly suggest that SJT would be a effective candidate for herbal-originated anti-asthmatic drug. However, this drug should be further studied for characterization of the accurate action and underlying mechanisms using variant disease model in the future.

This study aimed to evaluate the anti-asthmatic effects of Seonpye-tang (SPT) using OVA-induced asthmatic mice model. Scavenging activity of SPT on DPPH free radical and SOD-like activity of SPT were measured at final concentration 62.5, 125, 250, 500 (${\mu}g/m{\ell}$), RBL-2H3 cells were treated with DNP IgE for 24hr, and treated with SPT (1, 10, 100 ${\mu}g/m{\ell}$) for 1hr, followed by treatment with DNP-HSA for 1hr at $37^{\circ}C$. The level of IL-4 and TNF-${\alpha}$ were measured by ELISA. Asthmatic mice model was conducted by repeated challenge of OVA using C57BL/6 mice. Each group was treated with distilled water, SPT (400 mg/kg and 200 mg/kg) extract or cyclosporin A (10 mg/kg) for the later 8 weeks. Immune cells subpopulation, eotaxin, IL-5 and TNF-${\alpha}$ in BALF were analyzed. SPT dose-dependently increased Scavenging activity on DPPH free radical and SOD-like activity. SPT significantly ameliorated the increase of total cells number and eosinophil including of immune cell subpopulation of $CD3^+/CD69^+$, $CCR3^+$, $B220^+/CD22^+$, $B220^+/CD45^+$ and $B220^+/IgE^+$ cells in BALF comparing to control group. Eotaxin and IL-5 level in BALF were significantly decreased by SPT. These results strongly suggest that SPT would be a effective candidate for herbal-originated anti-asthmatic drug. However, this drug should be further studied for characterization of the accurate action and underlying mechanisms using variant disease model in the future.

Objectives: This study aims to investigate the effects of diabetes mellitus care mixture (DCM) on blood glucose and lipid metabolism in type 2 diabetic mellitus mice. DCM consisted of lagerstroemia speciose, allium hookeri, momordica charantia, amaranthus tricolor, and boesenbergia rotunda, which have been proven to have antidiabetic properties. Methods: In this study, we researched the effects of DCM in type 2 diabetic mellitus mice. C57BLKS/J mouse groups had no treatment, db/db mouse randomly assigned to 2 groups, and treated with distilled water and DCM (200 mg/kg/day). Blood glucose levels and body weight were checked every week. After 4 weeks of treatment, liver function indicators (AST, ALT, and LDH) and lipid metabolites (triglyceride, total cholesterol, LDL-cholesterol, HDL-cholesterol) were measured with a biochemistry analyzer. Diabetic factors (insulin, resistin, and leptin) were measured with ELISA. Results: DCM was decreased blood glucose, diabetic factors, liver function indicators, triglyceride, total cholesterol, and LDL-cholesterol significantly. Also, HDL-cholesterol was significantly increased in DCM group. The bodyweight of DCM group decreased but, no significant difference with the control group. DCM may have the potential to improved diabetes mellitus by regulating blood glucose levels and diabetic factors. Also protecting from diabetic complications by adjusting liver function indicators and lipid metabolites. Conclusions: These results suggest that DCM to be used as an oriental medicine for diabetes, the results of clinical trials are needed.

Objective: This study was conducted to investigate the effect of Chaenomelis Fructus (CF) water extract on thioacetamide (TAA)-treated rats. Methods: Rats were divided into five groups: one normal group (n=8) and four with TAA-induced hepatic injury. These treatment groups were administered distilled water (n=8); silymarin 100 mg/kg (n=8); CF 100 mg/kg (n=8); and CF 200 mg/kg (n=8). In the TAA groups, the acute liver injury was induced via IP injection (200 mg/kg), and the silymarin and CF extract were then orally administered for three days. Subsequently, serum levels of GOT, GPT, and ammonia were confirmed as well as protein expressions using liver tissue. Results: In the liver injury-induced rats, CF administration reduced tissue damage and serum levels of GOT, GPT, and ammonia. In addition, CF increased the anti-oxidant proteins Nrf2, Keap1, HO-1, and catalase and significantly regulated matrix metalloproteinases (MMP-2 and MMP-9) and their tissue inhibitors (TIMP-1 and TIMP-2). Conclusions: In this animal model of liver injury induced by TAA, CF extract is determined to have a hepatoprotective effect by increasing anti-oxidant proteins that relieve damage and by regulating the expression of matrix metalloproteinases.

The antibacterial activities of nine oriental herbal medicine extracts were measured against seven kinds of bacteria known to cause food poisoning and disease. The extracts were prepared with distilled water using an autoclave ($121^{\circ}C$ for 30 min). The extraction yields of nine oriental herbal medicines were in the rage of 0.5%-33.4%. The antibacterial activities were evaluated using the paper-disc method. Extracts of Hwangryeon, Jiyu, and Ohbaeja showed antibacterial activities while the others did not. Extracts of Coptis japonica, Hwangryeon, and Sanguisorba officinalis, Jiyu showed antibacterial activities only against Clostridium perfringens and Listeria monocytogenes. Extracts of Rhus javanica, Ohbaeja showed the strongest antibacterial activities against all the bacteria tested. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of R. javanica extracts were in the range of 2.4~20 mg/ml for the bacteria tested. In conclusion, the extract of R. javanica showed superior antibacterial activities against the seven bacterial strains tested. The MIC and MBC values for each bacterium were represented as strain names (MIC, MBC), which were Bacillus cereus (11.2, 20), Clostridium perfringens (2.4, 4.7), Escherichia coli (9.1, 9.1), Listeria monocytogenes (11.1, 20), Salmonella typhi (4.7, 9.1), Staphylococcus aureus (2.4, 4.7), and Vibrio parahaemolyticus (2.4, 5.3). Further purification and study of this antibacterial material would be helpful for developing antibiotics or promoting synergistic effects with known antibiotics, producing antibacterial material for lengthening the shelf-life of food, and so on.

Objectives This study's object was to observe the comparative effects of Yangkyuksanhwa-tang, Palmulgunja-tang and Cheongpyesagan-tang on the chronic LT4(levothyroxine) induced hyperthyroidism in rats.Methods Six groups, each of 8 rats in group, were used in this study. Saline and distilled water treated rats are intact control group. Hyperthyroidism was induced by daily subcutaneous LT4 300 μg/kg treatment for 27 days(LT4 control). Since 12th LT4 treatment PTU(propylthiouracil) 10 mg/kg was intraperitoneal injected(PTU group) and aqueous extracts of Yangkyuksanhwa-tang, Palmulgunja-tang and Cheongpyesagan-tang(YS, PG and CS) 500 mg/kg were orally administrated(YS, PG, CS group), once a day for 15 days. The differences in the body, thyroid gland and epididymal fat pad weights, serum T3(tri-iodothyronine), T4(thyroxine), TSH(thyroid-stimulating hormone), thyroid gland and epididymal fat pad histopathology, liver weight, AST(asparte aminotransferase), ALT(alanine aminotransferase) concentrations, hepatic lipid peroxidation, GSH(glutathione), SOD(superoxide dismutase), CAT(catalase) activities, liver histopathology were observed to evaluate effects on hyperthyroidism, liver damages and antioxidant effects.Results As results of LT4 treatment, hyperthyroidism and related liver damages such as lower body, thyroid weights, higher serum T3, T4, AST, ALT levels, thinner follicular lining epithelium in thyroid glands were observed. However, these symptoms were inhibited by oral treatment of YS, PG and CS. As compared with PTU treatment, these herbal prescriptions showed lower overall efficacy on the hyperthyroidism, but YS showed more favorable effects on the hepatic antioxidant defense systems.Conclusions This results suggest that YS, PG and CS favorably control the LT4 induced hyperthyroidism and related liver damages in rats through modulation of the hepatic antioxidative defense systems.

Objective: As the number of sarcopenic patients worldwide is increasing, the need for the treatment of sarcopenia is increasing. Ginseng has been reported to be a major herbal supplement. We tested whether red ginseng would be effective for sarcopenia using red ginseng preparation which can be easily obtained locally in Korea. Methods: 30 rats were randomly divided into three groups: the control group (n=10) (Group C), the group with Dexamethasone -induced sarcopenia (n=10) (Group D), and the group to which red ginseng was administered group after induced sarcopenia with Dexamethasone (n=10) (Group DH). Dexamethasone was intraperitoneally administered to group D and group DH for 7 days to make sarcopenic model. After that, the red ginseng tablets prepared by Korea Ginseng Corporation were diluted in distilled water and administered orally to the DH group for 2 weeks. Body weight and grip strength were measured 8 times during the experiment. At the end of the experiment, blood was collected by cardiac puncture. In addition, the tibialis muscle was extracted, a myofibril cross section was measured by immunohistochemical staining and MyHC (myosin heavy chain) was quantified by Western blotting. Results: The ratio of the area on myofibril cross-section showed significant differences after administration of the red ginseng tablet. Conclusions: Red ginseng has a significant effect on the recovery of myofibril cross-section on sarcopenia. This experiment will be helpful for future clinical studies on drug effects in sarcopennia.

Objectives: This study was performed to evaluate the skin irritation toxicity of processed sulfur. Methods: All experiments were conducted at Medvill (Korea), an institution authorized to perform non-clinical studies, under the Good Laboratory Practice (GLP) regulations. In order to investigate skin irritation toxicity of processed sulfur, we divided the back of six rabbits into two control sites and two test sites. One of each of the two control and test sites was then designated abraded sites and intact sites. In test sites, 0.5 g of processed sulfur was applied to the back of the rabbit for 24 hours, and in control sites, 0.5 g of sterile distilled water was applied in the same way. We observed and evaluated mortality, weight, general symptoms, and skin irritation toxicity. This study was conducted with the approval of the Animal Ethics Committee (Approval number: IAC2020-1549). Results: In all experiments, no dead animals were observed. In all cases, skin coloration was observed at 24 hours after processed sulfur administration. This coloration lasted up to 48 hours and is believed to be the effect of the administration of test substances. Weight measurement indicated that weight was lost 72 hours after administration in three cases, but this is considered an accidental weight change. Normal weight gain was observed in the remaining subjects. In all animals, no skin irritation toxicity was observed, and the primary irritation index (P.I.I) was calculated as 0.0 according to Draize's evaluation method. Conclusion: The above findings suggest that it is relatively safe to apply a processed sulfur to the skin. Further research on this topic is needed to provide more specific evidence.

목적 : 인진약침이 고지방식이로 유발된 비만 ICR mice에서 비만 및 동반 대사이상에 미치는 효과와 그 기전을 연구하고자 한다. 방법 : 인진약침의 비만 예방효과를 검증하기 위하여, 4주간 고지방식이를 급여하면서 150mg/kg 또는 300mg/kg의 인진약침을 양측 비수($BL_{20}$)에 교대로 매일 피하에 시술하였다. 또한 인진약침의 비만 치료효과를 검증하기 위하여, 4주간 고지방식이를 급여한 비만 ICR mice에 추가 4주간 고지방식이를 유지하면서 300 mg/kg 인진약침액과 vehicle control로써 등량의 distilled water를 양측 비수($BL_{20}$)에 교대로 매일 피하에 약침시술하였다. 인진약침의 항비만효과와 기전을 알아보기 위해, 체중, blood glucose, insulin, total cholesterol, triglyceride, non-esterified fatty acid (NEFA), AST, ALT levels 등 대사지표를 측정하고 부고환조직의 조직학적 관찰을 시행하였으며, AMPK activation과 adipocyte differentiation, fatty acid ${\beta}$-oxidation 및 thermogenesis와 관련된 gene expressions을 평가하였다. 결과 : 인진약침의 치료를 통하여 고지방식이 급여로 인한 체중의 증가가 억제되었을 뿐만 아니라, 비만 ICR mice의 체중을 감소시켰으며, glucose 및 lipid homeostasis를 개선시켰으며 지방조직의 증식을 억제하였다. AMPK의 phosphorylation과 CPT-1 및 UCP2의 발현을 증가시켰으며, PPAR-${\gamma}$, C/EBP${\alpha}$, aP2, LPL,FAS, SCD-1의 발현을 억제하였다. 결론 : 인진약침은 고지방식이 유도 동물모델에서 비만 및 동반 대사이상을 개선시키는 효과가 있으며, 이는 식이억제에 의한 2차적 효과라기 보다는 energy expenditure를 증가시키고, pre-adipocyte differentiation 및 proliferation을 억제하며, lipogenesis를 억제하고 lipolysis를 증가시키는 효과에 의한 것으로 사료된다.
