GLP-1-based drugs (GLP-1 analogues and DPP IV inhibitors) and incretin mimetics are currently one of the most exciting classes of agents for type II diabetes. GLP-1, a gut peptide, is an incretin that potentiates glucose-dependent insulin release from the pancreas, slows GI-transit and stimulates the proliferation of beta-cells. DPP IV inhibitors act like incretins by inhibiting DPP IV which inactivates GLP-1. LC15-0133 is a competitive, reversible DPP IV inhibitor ($IC_{50}$ = 24 nM, Ki=0.247 nM) with excellent selectivity over other critical human proteases such as DPP II, DPP 8, elastase, trypsin. and urokinase. LC15-0133 showed long half-life and good bioavailability in rats and dogs. Inhibition of plasma DPP IV activity by LC15-0133 was kept more than 50% 24 hours after oral dosing in rats and dogs at 0.1 mg/kg and 0.02 mg/kg, respectively. The Minimum effective doses of LC15-0133 were 0.01 mg/kg for lowering blood glucose excursion during oral glucose tolerance test and 0.1 mg/kg for increasing glucose-induced GLP-1 response in C57BL/6 mice. Repeat oral administration of LC15-0133 for 1 month delayed the progression to diabetes and reduced HbA1c levels in a dose-dependent manner in Zucker Diabetic Fatty rats. In conclusion, LC15-0133 is a novel, potent, selective and orally active DPP IV inhibitor and showed an excellent blood glucose lowering effects in various animal models.

Objectives: The aim of this study was to investigate the preventive effects of Sambok-go for upper respiratory tract infection. Methods: Sambok-go was performed to outpatients which had visited Daejeon university oriental medicine hospital. The number of participants who received Sambok-go at least once were 85, 21 patients did not receive Sambok-go three times were excluded first. Participants who received treatment three times were 64 patients. After the 2011 winter, 2012.05 we follow-up by telephone, except eight, 56 patients were analyzed. Sambok-go is composed of 8 kinds of medicinal herbs. Each Sambok-go weighs about 1.1g and attatchment surface diameter is about 1.5 cm. Sambok-go was attached to both side of 폐유(肺兪)(BL13), 심유(心兪)(BL15), 폐유(膈兪)(BL17), patients under the age of 15 were attached for an hour, patients over 15 years age were attatched for 3 hours. Results: Among the finally analyzed 56 participants, we compared the number of flu outbreak during winter before and after treatment. Before treatment measured $6.14{\pm}6.57$, after treatment measured $1.57{\pm}1.14$. In conclusion, the number of flu outbreak was significantly decreased(p<0.001). To investigate the effect of worsening factors on the pre-existing upper respiratory diseases, we checked whether the patients had pre-existing upper respiratory diseases. The patients who already had old upper respiratory diseases were 34. The increase in the frequency of deterioration in 5 patients, 4 patients no change, decreased in 24 cases, one patient was unresponsive. After evaluating the satisfaction of The patients who were treated with the Sambok-Go, the 29 cases were very satisfied, the 23 were satisfied, None of the paitents showed dissatisfaction or bad dissatisfaction. Conclusion: Sambok-go seems to be effective in the prevention of URI. Further studies are recommended to confirm this effect.

Acupuncture and Radix Astragali aqua-acupuncture stimuli have long been used to cure human diseases. However, it still remains to be unkown on its action mechanism, physiolosical and biochemical aspects. Thus, many attempts were made to show the scientific background covering the above mentioned mechanisms. Most recent studies show that these tests improve blood circulatory system and increase leucocyte counts. In this study, we have applied the acupuncture stimuli to mouse Sinsu(BL-23), which is a stimulative point of oriental medicine, to see if cytokine such as IL-6 can be detected. Mice were treated with lipopolysaccharide(LPS) for inflammation induction, and then reverse transcriptase-polymerase chain reaction (RT-PCR) using each primer set was performed to trace the amounts of mRNA. The results are summarized as follows ; 1. IL-6 was not temporarily expressed in normal mice 15 min after the acupuncture was pulled out. But, it started to show a feeble expression at 30 min after the removal of acupuncture and it started to reduce at 1h. after the acupuncture was pulled out 2. IL-6 was specifically expressed in LPS-treated mouse 30 min after the acupuncture was pulled out. The transcriptional expressions of LPS-treated mice were more effective than those of normal mice at 30 min after the removal of acupuncture 3. IL-6 was not temporarily expressed in normal mice 15 min after Radix Astragali aqua-acupuncture. But it expressed most highly at 30 min, and the transcriptional expressions of IL-6 was continued to 3 h. 4. IL-6 was not expressed in all the time after Radix Astragali aqua-acupuncture in LPS-treated mice. Therefore, a follow-up of cytokine IL-6 can be used not only a basis of the effect of acupuncture and Radix Astragali aqua-acupuncture but a diagnosis giude through the immunological action of thats. And, it is suggested that cytokine's expression by Acupuncture and Radix Astragali aqua-acupuncture stimulation should be continuously elucidated.

To investigate the hair growth activity of fractions and extract of Arisaematis Rhizoma in the hair removed skin of normal and spontaneous alopecia areata model in C57B/6N mice. These experiments were performed with the macroscopic, microscopic, immunohistochemical(VEGF, c-kit, PKC-${\alpha}$, TGF and FGF) and RT-PCR(TGF-${\beta}$, IGF, prolactin and placenta lactogen) methods. The results were as follows: Macroscopic observation after topical application of vehicle, 50% EtOH as control and extract of Arisaematis Rhizoma to the hair removed skin of C57BL/6N mice on the 9th, 11th and 15th day. Extensive hair growth activity was observed in treated group with extract of Arisaematis Rhizoma on the 9th, 11th and 15th day. In Arisaematis Rhizoma extracts treated group, hair follicles of middle stage of anagen was observed and it were grown down to subcutaneous tissue of skin in all the normal mice on 15th day. But in control group, most of hair follicles of telogen phase was observed in skin. The treatment of extract of Arisaematis Rhizoma increased expression of IGF(145%) and placenta lactogen(108%) in the skin of normal C57BL/6N mice on the 11th day compared to control group(100%). But expression of TGF-${\beta}$(90%) and prolactin(91%) decreased in the skin of normal C57B/6N mice on the 11th day compared to control group(100%). After application of fractions(chloroform, ethyl acetate and water fractions) of Arisaematis Rhizoma extract for 9th day, hair growth effect was observed in whole skin area in 50% of normal mice. But in control group, hair growth effect was not observed in whole skin area of normal mice. Immunoreactive density of VEGF, c-kit, PKC-${\alpha$ and FGF in skin of fractions of Arisaematis Rhizoma extracts was strongly stained in epidermis, bulge, secondary hair germ cells, cutaneous trunci m., subcutaneous tissue, root sheath compare to control group on the 9th day. In spontaneous alopecia areata model, The hair growth activity of Arisaematis Rhizoma extrat treated group(75%) was observed to be strong compared to control group(O%) on 7th day. These experiments suggest that fractions and extracts of Arisaematis Rhizoma may stimulate the topical hair growth activity. Thus it can be useful for treatment of alopecia areata.

This study was conducted to develop effective manufacturing methods of a total mixed ration(TMR) composed of broiler litter(BL) and bakery by-product(BB) for ruminants. Five experiments included a small-scaled manufacture of TMR using a deepstacking method(Exp. 1), its pelletization(Exp. 2), its field-scaled manufacture(Exp. 3), a field-scaled manufacture using an ensiling method(Exp. 4), and a mixing process of deepstacked BL and BB prior to feeding(Exp. 5). BL and BB were mixed at a ratio which makes total digestible nutrients of the TMR 69%. For each experiment, temperature, appearance and physico-chemical properties were recorded and analyzed. The chemical composition data revealed that the mixture of BL and BB showed nutritionally additive balance which resulted from a considerable increase(P<0.05) of organic matter and a desirable decrease(P<0.05) of protein and fiber up to the requirement level for growing ‘Hanwoo’ steers. Deepstacking of BL and BB in Exp. 1 and 3 resulted in a sufficient increase of stack temperature for pasteurization, little chemical losses, appearance of white fungi on the surface, and partial charring due to excess stack temperature. For Exp. 2, its pelleting, which was successful using a simple, small-scaled pelletizer, resulted in a little loss(P<0.05) of organic matter and an increase(P<0.05) of indigestible protein(ADF-CP). Ensiling the mixture in Exp. 4 made little effect on chemical composition; however, one month of the ensiling period was not enough for favorable silage parameters. Deepstacking BL alone in Exp. 5 tended(P<0.1) to decrease true protein : NPN ratio and hemicellulose content and increase ADF-CP content due to the heat damage occurred. Deepstacking or ensiling of BL-BB mixtures and simple incorporating of BB into deepstacked BL prior to feeding could be practical and nutrients-preservative methods in TMR manufacture for beef cattle, although ensiling needed further hygienic evaluation.

In this study, 4-week-old rats were fed bread supplemented with Terminalia chebula (TC), Plantago asiatica (PA), Linder obtusiloba (LO), and Capsosiphon fulvescens (CF) ethanol extracts, to determine the decrease in blood glucose levels, as well as the anti-inflammatory and lipid-enhancing effects. Previous studies have demonstrated the antioxidative effects of these ethanol extracts. After sacrifice, the liver tissue, whole blood, and serum samples were collected for biochemical analysis. The results showed a significant decrease in blood glucose level, lipid peroxidation, malondialdehyde (MDA) level, HbA1c level, total cholesterol, and low-density lipoprotein (LDL)-cholesterol (p<0.05) and an increase in high-density lipoprotein (HDL)-cholesterol level in rats fed bread supplemented with LO and CF ethanol extracts (p<0.05). Therefore, the results of this study demonstrate that bread supplemented with LO and CF ethanol extracts can potentially affect the blood glucose level and lead to lipid enhancement.

Sprain is the injury of meridian-muscle, and is caused by qi and blood obstruction or regional stagnation of qi and blood. So we take the channel points where pain flows. If we take the locations that feel pain, those locations are treatments points and ashi points. So we searched over the ashi points appearing on the patients with wrist sprain. Ashi points appeared on LI5, TE4, SI5 around wrist joints, LI10, LI11, LU6 around elbow joints, LI14, LU3, LU4, PC2 around upper arm. Also, ashi points appeared much on ST17, KI23, PC1, SP18, ST18 around thoracic region, and, on BL15, BL44, BL13 around anterior and thoracodorsal region, in order stated. Ashi points of the highest frequency appeared on LI14 around upper arm, and on LI5, TE4 around wrist joint, and SI5, ST17, KI12, PC1, SP18 appeared with second highest frequency. And ashi points on elbow points and thoracodorsal region appeared with the same frequency. Therefore, it is possible for us to know that the pain location appears in order of upper arm, anterior thoracic region, elbow joint region, and, thoracodorsal region, in treating wrist joints. There was a tendency that pain and movement disturbance recovered more quickly, depending on the pain reduction, as we found out the ashi points closely from stagnated qi and blood caused by wrist arthritis, and relaxed the stiff location. Rubbing treatments in treating pain ashi points is considered to play an important role to reduce pain effectively, so it is necessary to make a further study.

Objectives Acupoint sticking in Dog-Days is one of Oriental medical prophylaxis to prevent winter diseases over the summer. The research has been conducted to evaluate the efficacy of Acupoint sticking in Dog-Days. Methods We visited one kindergarten in Dog-Days of 2011, and the subjects were 72 children (38 boys, 34 girls, $58.24{\pm}12.28$ months, 37-105 months). 72 children were attached Socheongo to BL-13, BL-15, BL-17 for 4-6 hours. Exacerbating effect or non-improvement in respiratory symptoms before and after the treatment were nullified. Results 31 children (43.1%) have shown positive effect in Socheongo, with no significant differences among the groups. There were significant improvements in Socheongo group in frequency of having cold, duration and visits; duration under tonsillitis, frequency of having otitis media, duration and visits (P<0.05). Lung weak score also had significant decrease in the three times Socheongo group, from $11.27{\pm}5.61$ to $9.90{\pm}4.66$ (P=0.030). Side effects has been reported in Socheongo group; 7 erythema (9.7%), 2 heating (2.8%), 9 pruritis (12.5%), 2 vesicle (2.8%), 13 scar (18.1%). Conclusions Acupoint sticking in Dog-Days improves lung weak symptoms such as common cold, tonsilitis, and otitis media in children older than three years old, throughout the three times of the treatment. However, the ways to reduce the side effects are needed.
