Objective : This study was carried out to investigate the effect of Hwangryeonhaedoktang pharmacopuncture solution (HRHDT) and microneedle therapy system (MTS) on hair growth in an alopecia model of C57BL/6N mice.Methods : Six-week old mice were depilated and separated in 4 groups ; CON (saline), MXD (3% Minoxidil), MTS and HRHDT+MTS. The treatments were applied twice a week for 17 days. The hair growth was determined photographically. The hair density, thickness and length were identified by Folliscope and the weights of body and organs were measured. In dorsal skin tissue, the expression of hair growth-related gene and protein was analyzed by RT-PCR. In addition, the hair follicles in the dermis were observed by H&E staining.Results : The promotion of hair growth was observed in HRHDT+MTS and MTS compared to CON. The hair density, thickness and length were also improved in HRHDT+MTS and MTS compared to CON. The mRNA expression of IGF-1, PRL and PL and the protein expression of VEGF and IGF-1 were increased in HRHDT+MTS and MTS compared to CON. The hair follicles and hair root growth were improved in HRHDT+MTS and MTS compared to CON. In the above results, HRHDT+MTS were more effective than MTS.Conclusions : These results suggest that HRHDT and MTS have a hair growth activity and can be useful for the treatment of alopecia.

Objectives : The purpose of this study was to find out the efficacy of ginseng on the skin by comparing the difference effect between only MTS (microneedle therapy system) and the ginseng solution application after MTS treatment. Methods : The present author performed once a week and total 3 times of MTS treatment. The treatment time took about 5~10 minutes and the depth of the needle was adjusted according to the participant's skin condition. In the control group, skin toner was applied after MTS and in the experimental group, ginseng extract dissolved toner was applied. One week after each treatment, the change of skin condition was measured. Two weeks after the end of the clinical trial, the skin condition was checked again. Results : In the case of t-zone oil, there was a significant decrease in the test group and in the case of pores and pigmentation, there was a significant decrease in both the test group and the control group, but the degree of significance was greater in the test group. In the case of skin tone, there was an increase, but no significance. Conclusion : The MTS treatment itself showed good effects on t-zone oil, pores, pigmentation, and skin tone. But the effect was much better when the ginseng extract solution was applied to the skin after MTS treatment. This study suggests that ginseng solution increases the efficacy of MTS.

Objectives : The purpose of this research was to find out the efficacy of Castanea crenata Inner Shell (CCIS) on the skin by comparing the difference effect between only MTS (microneedle therapy system) and the CCIS essence application after MTS treatment. Methods : The present author performed once a week and total 3 times of MTS treatment. The treatment time took about 5 ~ 10 minutes and the depth of the needle was adjusted according to the participant's skin condition. In the control group, essence base was applied after MTS and in the experimental group, CCIS powder dissolved essence was applied. One week after each treatment, the change of skin condition was measured. Two weeks after the end of the clinical trial, the skin condition was checked again. Results : In the case of the test group and the control group, there was a significant decrease in thermography temperature and there was a significant increase in skin tone. In the case of pores and pigmentation, there was no significant difference on both group. In the case of moisture, there was a significant increase only in the test group. Conclusion : The MTS treatment itself showed good effects on thermography temperature and skin tone. But in the case of the moisture effect, it was much better when the CCIS essence was applied to the skin after MTS treatment. This study suggests that CCIS essence increases the efficacy of MTS on the point of moisture.

The development of selective targeting of drug molecules towards the mitochondria is an important issue related to therapy efficacy. In this study, we report that gallic acid (GA)-mitochondria targeting sequence (MTS)-H₃R₉ exhibits a dual role as a mitochondria-targeting vehicle with antioxidant activity for disease therapy. In viability assays, GA-MTS-H₃R₉ showed a better rescue action compared to that of MTS-H₃R₉. GA-MTS-H₃R₉ dramatically exhibited cell penetration and intercellular uptake compared to MTS and fit escape from lysosome release to the cytosol. We demonstrated the useful targeting of GA-MTS-H₃R₉ towards mitochondria in AC16 cells. Also, we observed that the antioxidant properties of mitochondrial-accrued GA-MTS-H₃R₉ alleviated cell damage by reactive oxygen species production and disrupted mitochondrial membrane potential. GA-MTS-H₃R₉ showed a very increased cytoprotective effect against anticancer activity compared to that of MTS-H₃R₉. We showed that GA-MTS-H₃R₉ can act as a vehicle for mitochondria-targeting and as a reagent for therapeutic applications intended for cardiovascular disease treatment.

암조직의 내부에서 hypoxia와 glucose depletion 등의 microenvironmental stress를 받게 되면 necrosis가 유도되고, 실제로 암 조직 내부에서 necrotic core 형성이 관찰된다. Necrotic cells은 high mobility group box 1(HMGB1)를 extracellular space로 방출하는 것으로 알려져 있다. 방출된 HMGB1은 tumor-promoting cytokine으로 작용함으로써 tumor development 시 inflammation, metabolism 및 metastasis에 기여한다. 본 연구에서 non-invasive breast cancer cells MCF-7이 solid tumor의 in vitro model인 multicellular tumor spheroid (MTS) 배양을 통해 완전한 구형의 MTS를 형성하며 MTS가 성장함에 따라 inner region에 necrosis가 유도됨을 밝혔다. 또한 MCF-7 세포의 MTS 배양은 Snail 의존적으로 epithelial-mesenchymal transition (EMT)를 유도함을 관찰하였다. HMGB1의 cell surface receptors인 RAGE, TLR2, TLR4 발현이 MTS 배양에 의해 증가됨을 발견하였다. RAGE, TLR2, TLR4 를 knockdown한 결과 MTS 성장을 억제할 뿐만 아니라 MTS에 의해 증가되는 Snail 발현을 억제함을 밝혔다. 이는 MTS-induced Snail 발현이 RAGE/TLR2/TLR4의존적으로 조절되며 RAGE/TLR2/TLR4-Snail이 MTS 성장에 관여하는 것으로 보인다. 또한 Snail, RAGE, TLR2, TLR4 shRNA는 MTS 배양에 의해 유도되는 EMT를 억제함을 밝혔다. 실제 인간 암조직에서 정상조직에 비해 RAGE, TLR2, TLR4 유전자의 발현이 높음을 관찰하였다. 따라서 HMGB1이 RAGE/TLR2/4-Snail axis를 통해 MTS 배양에 따른 성장 및 EMT에 중요하게 작용할 것으로 예상된다.

Two genes encoding maltooligosyltrehalose synthase (SaMTS) and maltooligosyltrehalose trehalohydrolase (SaMTH) were isolated from a hyperthermophilic microorganism, Sulfolobus acidocaldarius (ATCC 49462). ORFs of the SaMTS and SaMTH genes are 2,163 and 1,671 bp long and encode 720 and 556 amino acid residues, respectively. A bifunctional fusion enzyme (SaMTSH) was constructed through the gene fusion of SaMTS and SaMTH. Recombinant SaMTS, SaMTH, and SaMTSH fusion enzyme were overexpressed in E. coli BL21. SaMTS and SaMTH produced trehalose and maltotriose from maltopentaose in a sequential reaction. SaMTSH fusion enzyme catalyzed the sequential reaction in which the formation of maltotriosyltrehalose was followed by hydrolysis leading to the synthesis of trehalose and maltotriose. The SaMTSH fusion enzyme showed the highest activity at pH 5.0-5.5 and $70-75^{\circ}C$. SaMTS, SaMTH, and SaMTSH fusion enzyme were active in soluble starch, which resulted in the production of trehalose.

This study investigated the effect of allium vegetable intake on the storage and utilization of energy substrates before, during, and after exercise in tissues of rats. Ninety mts were fed either a control diet or a diet with added allium sativum (AS), allium cepa (AC), allium fistulosum (AF), or allium tuberosum (AT) for 4 weeks and then subdivided into 3 groups: before-exercise (BE) during-exercise (DE) after-exercise (AE). The DE group exercised on treadmill for 1 hour just before being sacrificed at the end of the 4th week of the dietary treatment Rats in the AE group were allowed to recuperate for 2 horns after being exercised like the DE group. Pyriooxal 5'-phospwe (PLP) levels were compared in plasma, liver and skeletal muscle of rats. There was no difference between AS animals and control animals in plasma PLP levels regardless of exercise. The plasma PLP levels of AC animals were higher than those of control animals before exercise but this PLP was decreased with exercise and lower than that of control animals after exercise. The plasma PLP levels of AF animals were higher than those of control animals during exercise but there was no difference before and after exercise. The plasma PLP levels of AT animals were higher than those of control animals regardless of exercise. Compared to those of control mts, the PLP levels of liver and muscle were significantly lower in AS, AC, AF and AT mts before exercise. The levels of liver PLP were significantly decreased in control mts while not changed in AS, AC, AF and AT mts during exercise. The levels of liver PLP tended to decrease in AS, AC and AF mts after exercise. The levels of muscle PLP were significantly decreased in control rats, while not changed in AS, AC and AF mts during exercise. The levels of muscle PLP were decreased in control mts but not changed in AS, AC and AF mts after exercise. Thus, it is suggested that the changes of PLP concentrations in plasma and tissues induced by exercise are affected by allium vegetable diet and demonstrated that allium vegetable intake induced an alteration in the redistribution of PLP among tissues.
