The purpose of this research is to evaluate the effect of Mahaenggamseok-tang-gagambang (MGTG) on airway hyper- responsiveness (AHR), immune cells, cytokines and lung tissue in OVA-induced asthmatic mice. C578L/6 mice were injected, inhaled and sprayed with OVA for 12 weeks (3times a week) for asthma sensitization and challenge. Two experimental groups were treated with different concentrations of MGTG (400 mg/kg and 200 mg/kg) extract and cyclosporin A (10 mg/kg) for the later 8 weeks. Enhanced pause (Penh) levels were measured by whole body plethysmography. Immune cells were analyzed by flow cytometer in peripheral blood monocyte cell (PBMC) and lung cells. The IL-1b, IL-12, IFN-${\gamma}$, OVA-lgE, IL-4, IL-5, TNF-${\alpha}$ were analyzed by ELISA kit in serum and splenocyte+a-cCDS/a-CD28. Enhanced pause (Penh) levels of the MGTG groups (400 mg/kg and 200 mg/kg) were decreased significantly compared with that of control group. The numbers of MGTG groups (400 mg/kg and 200 mg/kg) on lung total cells were decreased significantly compared with that of control group. The numbers of MGTG groups (400 mg/kg and 200 mg/kg) on $CD3^+/CD69^+$, $B220^+/CD22^+$, $B220^+/CD23^+$, $B220^+/lgE^+$, $CCR3^+$ cells were decreased significantly compared with that of control group. The number of MGTG group (400 mg/kg) on $CD3^+/CD49b^+$ cells was decreased significantly compared with that of control group. The level of MGTG groups (400 mg/kg and 200 mg/kg) on IL-4, IL-5, IL-12, TNF-${\alpha}$, OVA-lgE were decreased significantly compared with that of control group. The level of MGTG group (400 mg/kg) on IL-1b, IL-1S, OVA-lgE were decreased significantly compared with that of control group. These results demonstrate that MGTG could be a desirable alternative therapy for allergic asthma by inhibiting the expression of immune cells, the activation of inflammatory mediator.

Astragali Radix (AR) has been used in traditional medicinal herb, which is known to tonify the qi and blood. It has been asserted to be a tonic that can improve the function of the lungs, adrenal glands and the gastrointestinal tract, increase metabolism, promote healing and reduce fatigue. Also, Plantago asiatica (PA) has the anti-inflammatory, antiseptic, antitussive, cardiac, diuretic, expectorant, haemostatic effects, though it is considered to be less powerful than the seed. Recent research is showing that it is promising in lowering cholesterol and controlling diabetes. Obesity is characterized at the cellular level by an increase in the number and size of adipocytes differentiated from fibroblastic preadipocytes in adipose tissue. In the present study, we investigated the effects of 3 to 7 extracts of mixed medicinal herbs (water and ethanol extract of Astragali Radix; ARW and ARE, water and ethanol extract of Plantago asitica; PAW and PAE, and those mixed extracts; ARW+PAE, ARW+PAW and ARE+PAE) on adipogenesis and apoptosis in 3T3-L1 adipocytes by MTT assay, Oil-Red-O staining and TUNEL assay. And then, we determined total contents of phenolic compounds and flavonoid compounds in mixed herbal extracts. These result showed that herbal extracts (ARW, PAE and ARW+PAE) affected on adipogenesis and apoptosis in 3T3-L1 adipocytes among 3 to 7 extracts tested. Especially herbal mixed extracts (ARW+PAE) had the highest inhibition on differentiation of preadipocytes and lipoid accumulation of maturing adipocytes. And it did not affect cell viability of mature adipocytes, but herbal mixed extracts (ARW+PAE) increased apoptosis in mature adipocytes, as proved by highest concentration $200\;{\mu}g/m{\ell}$ using TUNEL assay. In addition, contents of total phenoilc compounds and flavonoids showed the highest level in ARE+PAE and PAE than ARW. These results suggest that this main target for adipocyte functions could be effective in improving the metabolic syndrome including obesity.

Hematological and serum biochemical analyses are routinely used to screen dogs for disease and monitor their clinical progression. These values in dogs may be affected by internal factors, such as breed and age, and external factors like environment, diet, and lifestyle. Apparently, subclinical breed-related variations in hematologic and serum biochemical results have been characterized for Bernese Mountain dogs, Alaskan Malamutes, English Setters, and Golden Retrievers. It is possible that some breed-related differences in clinical pathology analyses may reflect evidence of underlying disease and impact clinical decision plan. In this study, we estimated hematologic and serum biochemical parameters in small breed dogs and compared among four different breed dogs. Blood samples were collected from 38 domestic dogs that were 10 Beagles, 9 Malteses, 10 Poodles, and 9 Miniature Schnauzers. In terms of RBC count, Beagle ($7.2{\pm}0.24{\times}10^3cells/{\mu}L$) showed significantly (P<0.05) higher count than other breeds (Maltese, $6.51{\pm}0.25{\times}10^3cells/{\mu}L$; Poodle, $6.35{\pm}0.24{\times}10^3cells/{\mu}L$; and Miniature Schnauzer, $6.35{\pm}0.25{\times}10^3cells/{\mu}L$). For MCV, Miniature Schnauzer ($67.05{\pm}0.84fl$) results were significantly (P<0.05) higher than Beagle with $64.33{\pm}0.8fl$. For cholesterol value, Beagle ($163.3{\pm}9.15mg/dl$) had significantly (P<0.05) higher values than Miniature Schnauzer with $119.12{\pm}9.64mg/dl$. There was no statistically difference among breeds in terms of enzyme markers of liver diseases. In conclusion, data obtained from this study may be valuable as breed-related variability for interpretation of the results in hematologic and serum biochemical analysis among four small breed dogs.

Diabetes is a disease that contains a high concentration of glucose in blood and due to defects in either insulin secretion or insulin action. Although the distinctive causes and factors of diabetes have not been clarified, the genetic factors are suggested as a main susceptibility until now. SNP (Single Nucleotide Polymorphism), as the most common genetic variation, has an influence on personal susceptibility for diseases. A nonsynonymous SNP, which changes the amino acid of the protein and its function, is especially important. Therefore, this study hypothesized that there are associations between specific SNPs of the targeted genes. Transcription factor 7-like 2 (TCF7L2) and fat mass and obesity associated (FTO) genes were selected as target genes from the results of genome-wide association and other related research studies. Second, four nonsynonymous SNPs (three in TCF7L2 and one in FTO gene) were selected as target SNPs by using public database of NCBI (National Center for Biotechnology Information). The recruited personnel was classified into three subgroups of diabetes, impaired fasting glucose (IFG) and normal groups. The individual genotypes of each group were analyzed by resequencing. None of genetic variations at four targeted SNP sites was revealed in all samples of this study. However, this study found two new SNPs that were not reported in TCF7L2 gene. One is synonymous SNP, which is heterozygous of C/T and no amino acid change of asparagine/asparagines, was located at c1641 and found in one normal person. Another is nonsynonymous SNP, which is heterozygous of G/A, was located at c1501 and found in two samples. This new discovered nonsynonymous SNP induce the amino acid change from alanine to threonine. Moreover, this new nonsynonymous SNP was found among two persons, one of whom was a diabetes patient and the other one was a person at boundary between IFG and normal, suggesting that this variant might be associated with IFG or diabetes. Even if there is a limitation of sample number for statistical power, this study has an importance due to the discovery of new SNPs. In the future study, a large sample number of diabetes cohort will be needed to investigate the frequency and association with new discovered SNP.

Vascular tone plays an important role in the regulation of blood pressure. In the present study, the methanol extract of Rosae multiflora Radix (MRM) induced dose-dependent relaxation of phenylephrine-precontracted aorta, which was abolished by removal of functional endothelium. Pretreatment of the endothelium-intact aortic tissues with $N^G$-nitro-L-arginine methly ester (L-NAME) or 1H-[1,2,4]-oxadiazole-[4,3-${\alpha}$]-quinoxalin-1-one (ODQ) inhibited the relaxation induced by MRM, respectively. But, the relaxation effect of MRM was not blocked by indomethacine, glibenclamide, tetraethylammonium (TEA), verapamil, diltiazem, atropine, and propranolol, respectively. Moreover, incubation of endothelium-intact aortic rings with MRM increased the production of cGMP. Taken together, the present results suggest that MRM relaxes vascular smooth muscle via endothelium-dependent nitric oxide/cGMP signaling. These results would be useful for further study to MRM on animal models with cardiovascular diseases.

Mylabris is the dried body of the chinese blister beetle. The species used in medicine are Mylabris phalerata and M. cichorii. In recent studies, it has been found that Mylabris possesses antitumor properties, increases the number of leukocytes, and has irritant effects on the urinary organs. The crude extracts of Mylabris have been noted for their highly irritant action and other traditional uses of Mylabris include treatment of poor local blood circulation. The active constituent of Mylabris is cantharidin. The chemical is notable for its vesicant properties, but with severe side effects such as nephrotoxicity. This experiment examined the effect of extracts and fractions, obtained from Mylabris phalerata Pall. on hair growth activity of the C57BL/6N mice after topical application to skin. First, we examined the effect of an extracts, obtained from the alcohol extracts of dried Mylabris phalerata Pall. on hair growth activity of the C57BL/6N mice after topical application to skin. Second, we examined on hair growth activity of the cantharidin fraction of Mylabris phalerata Pall. compared to the control and 1% minoxidil groups. Third, we investigated the number of hair follicle and mast cells after topical application of extracts of Mylabris phalerata Pall. to skin for 16 days. The results were as follows: Hair growth effect from the extracts of Mylabris phalerata Pall.(0.312%) was observed in 80% of mice whose hair had been removed in 13 days. Hair growth effect from the extract of Mylabris phalerata Pall.(0.312 and 0.625%) and 1% minoxidil group was observed in 100% of mice whose hair had been clipped in 20 days. Hair growth effect from the cantharidin fraction(0.5%) and water fraction(0.5%) of Mylabris phalerata Pall. was observed in 100% of mice whose hair had been clipped in 24 days. The hair growth effect on the cantharidin fraction(0.125%) was observed to be strong compared with the minoxidil(3%) group, commercial hair growth agents, in mice whose hair had been clipped in 19 days. In the spontaneous alopecia mice model, the hair growth effect from the cantharidin fraction (0.125%) was observed to be strong as compared with the states before the 13 days experiment. These experiments suggest that extracts and fractions of Mylabris phalerata Pall. may stimulate the topical hair growth activity in low doses.

통각정보나 과탄산증이 내재진통계를 활성화 시켜서 진통효과를 가져온다는 것은 잘 알려져 있다. 이 러한 일련의 과정에서 중추신경세포의-역활에 대한 체계적인 연구가 요구되는 바, 16마리의 성숙한 고 양이를 u-chloralose로 마취한 후 연수 및 좌골신경을 노출시켜, 상부연수의 복외측부(rostral ventrolateral medulla, 이후 RVLM으로 칭함)세포활동이 탄산가스분압의 변동에 어떠한 영향을 받는 지를 관찰하였다. RVLM에서 세포의 기록법으로 그 변화를 관찰한 바, 총 53개의 세포에서 자발적 인 활동을 보였고, 이 중 28개는 심맥관계 세포, 16개는 호흡관련 세포, 2개는 심맥관계-호흡 동시 관련 세포이었으며, 7개는 자발적 활동은 보이나 심 장주기나 호흡주기와 무관 하였다. 28개의 심맥관계 세포중 11개에서는 동맥혈내 탄산가스분압이 상승하였을때 세포 활동이 증가하고, 13개 세포에서는 반대로 감소하였으며, 나머지 4개 에서는 특별한 변화가 없었다. 16개의 호흡관련 세포중 9개에서는 동맥혈내 탄산가스분압이 상승하였을때 활동이 증가하고, 6개에 서는 감소하였으며 1개는 특별한 변화가 없었다 B개의 심맥관계-호흡관련 세포에서는 탄산\ulcorner스 분압의 상승에 큰 영향을 받지 않았다. 심 장 혹은 호흡주기와 무관하였던 7개의 세포중 4개는 동맥 혈 탄산가스 분압이 상승하였을때 세포 활 동이 감소하였고, 2개는 상승하였으며 1개는 큰 영향을 받지 않았다 말초신경 자극과 동시에 탄산가스분압을상승시켰을 때 심먹관계 세포의 A반응은큰 영향이 없었으 나 C반응은 상승하였다. 결론적으로 RVLM에는 동맥혈 탄산가스 분압이 상승하였을 때 활동이 증가하는 세포들이 존재하고, 이때 말초화학 감수기의 영 향보다는 탄산가스가 중추에 직접 작용할 가능성이 크며 과탄산증에 의한 내 재진통작용도 RVLM을 통하지는 않는다고 생각된다.
