The purpose of this study was to determine the hair growth effects of lavender oil (LO) in female C57BL/6 mice. The experimental animals were divided into a normal group (N: saline), a vehicle control group (VC: jojoba oil), a positive control group (PC: 3% minoxidil), experimental group 1 (E1: 3% LO), and experimental group 2 (E2: 5% LO). Test compound solutions were topically applied to the backs of the mice ($100{\mu}L$ per application), once per day, 5 times a week, for 4 weeks. The changes in hair follicle number, dermal thickness, and hair follicle depth were observed in skin tissues stained with hematoxylin and eosin, and the number of mast cells was measured in the dermal and hypodermal layers stained with toluidine blue. PC, E1, and E2 groups showed a significantly increased number of hair follicles, deepened hair follicle depth, and thickened dermal layer, along with a significantly decreased number of mast cells compared to the N group. These results indicated that LO has a marked hair growth-promoting effect, as observed morphologically and histologically. There was no significant difference in the weight of the thymus among the groups. However, both absolute and relative weights of the spleen were significantly higher in the PC group than in the N, VC, E1, or E2 group at week 4. Thus, LO could be practically applied as a hair growth-promoting agent.

The present study was designed to investigate the anti-diabetic effect and mechanism of Korean red ginseng in C57BL/KsJ db/db mice. The db/db mice were divided into three groups: diabetic control group (DC), Korean red ginseng group (KRG, 100 mg/kg) and metformin group (MET, 300 mg/kg), and treated with drugs once per day for 10 weeks. Compared to the DC group, fasting blood glucose levels were decreased by 19.8% in KRG-, 67.7% in MET-treated group. With decreased plasma glucose and insulin levels, the insulin resistance index of the KRG-treated group was reduced by 27.6% compared to the DC group. The HbA1c levels in KRG and MET-treated groups were also decreased by 11.0% and 18.9% compared to that of DC group, respectively. Plasma triglyceride and non-esterified fatty acid levels were decreased by 18.8% and 16.8%, respectively, and plasma adiponectin and leptin levels were increased by 20.6% and 12.1%, respectively, in the KRG-treated group compared to those in DC group. Histological analyses of the liver and fat tissue of mice treated with KRG revealed significantly decreased number of lipid droplets and decreased size of adipocytes compared to the DC group. From the pancreatic islet double-immunofluorescence staining, we observed KRG has increased insulin contents, but decreased glucagon production. To elucidate action mechanism of KRG, effects on AMP-activated protein kinase (AMPK) and its downstream target proteins responsible for fatty acid oxidation and gluconeogenesis were explored in the liver. KRG activated AMPK and acetyl-coA carboxylase (ACC) phosphorylations, resulting in stimulation of fatty acid oxidation. KRG also caused to down regulation of SREBP1a and its target gene expressions such as FAS, SCD1 and GPAT. In summary, our results suggest that KRG exerted the anti-diabetic effect through AMPK activation in the liver of db/db mice.

Objectives The purpose of this study is to understand effect on respiratory disease and satisfaction of parents about acupoint sticking in hottest period of summer. Methods A survey was conducted to the parents of their children who took acupoint sticking in Dog-days for two years in a row. 17 children (10 boys, 7 girls, 4.0-12.11 years) were attached Socheongo to BL-13, BL-15, BL-17 for 3 hours. In terms of the effectiveness of the therapy, the treatment only considered as effective when there is any improvement in respiratory symptoms. Results 11 children (64.7%) from the study group have shown positive effect. There were significant improvements in frequency of having a cold or duration of a cold; duration of rhinitis; frequency of having empyema or its duration; frequency of having bronchitis; frequency of having pneumonia; frequency of having otitis media. Respiratory health VAS (Visual Analog Scale) had significant increase from 5 to 6.71 (p<0.05). 7 parents (41.2%) were satisfied with acupoint in hottest period of summer and 16 parents (94.1%) wanted to have their children get treated again in next year. From the survey, inconveniences of acupuncture were weak attachment of the acupoint (23.5%), long attaching time (11.8%), pressure about number of treatments (5.9%), worry about side effects (5.9%). Side effects have been reported; 2 pruritus (11.8%), 1 pruritus and erythema (5.9%). Conclusions Acupoint sticking in hottest period of summer improves lung symptoms in children older than three years old. However, the ways to reduce the side effects and inconveniences are needed.

본 논문에서는 Magnachip $0.18{\mu}m$ 공정을 이용하여 PMIC용 32bit eFuse OTP IP를 설계하였다. eFuse 링크 아래에 N-Well을 두어 프로그램시 eFuse 링크와 p-기판의 VSS가 단락되는 문제점을 해결하였다. 그리고 디코딩된 WERP (WL Enable for Read or Program) 신호가 eFuse OTP 메모리로 바로 입력되는 경우 듀얼 포트 eFuse OTP 메모리 셀의 RWL (Read Word-Line)과 WWL (Write Word-Line)을 선택적으로 활성화해 주는 WL 구동회로를 제안하였다. 또한 BL 프리차징 회로에서 delay chain을 제거하여 제어회로의 레이아웃 면적을 줄였다. 메모리 테스트 장비를 이용하여 제작된 94개의 샘플 die를 측정한 결과 5.5V의 프로그램 전압에서 100%의 수율을 얻었다.

Exposure to ultraviolet B(UVB) radiation causes skin inflammation such as pigmentation and the induction of cyclooxygenase-2(COX-2) gene expression. In this study, we investigated the effect of natural extracts from Tea, EGb 761 and Korean red ginseng(KRG), on the pigmentation and expression of COX-1 and COX-2 mRNA in UVB-irradiated C57BL/6 mice. Before UVB irradiation, the skin color was significantly showed the lightening effect by topical application of natural compounds (p<.05). In the case of UVB irradiated mice, we observed a decrease in pigmentation by compounds (p<.05). In irradiated skin, COX-1 mRNA expression is not changed following UVB irradiation, but COX-2 gene increases. Also, natural compounds lowered mRNA levels of COX-2. Therefore, these results suggest that COX-2 mRNA increases by UVB irradiation. Also, Tea, EGb 761 and KRG as a topical application may inhibit skin pigmentation and modulate COX-2 mRNA level.

The purpose of this case study is to report the effect of electroacupuncture at acupoints Baliao (BL31 Shangliao, BL32 Ciliao, BL33 Zhongliao, BL34 Xialiao) on patients with voiding problem. Neurogenic Bladder can be classified according to whether impairment of urinary reservoir or emptying. The first case was a patient with urinary emptying impairment. He was diagnosed with areflexic neurogenic bladder, and was managed with suprapubic cystostomy. After starting of electroacupuncture on Baliao, residual urine volume was gradually decreased, at last cystostomy could be removed. The second case was a patient with urinary reservoir impairment. She complained symptoms of urinary frequency, nocturia due to overactive bladder. After starting of electroacupuncture on Baliao, urination frequency was significantly decreased. We consider electroacupuncture on Baliao may have a useful effect on voiding problem, both urinary reservoir and emptying impairment.

고지방식이(High fat diet, HFD)에 의해 유발되는 비만은 정상적인 마우스에서는 연구되지 않았지만 여러 유전자변형마우스의 전립선암(Prostate cancer)에 대한 강력한 위험인자 및 예후인자로 검증되었다. HFD-유도 비만이 정상적인 마우스에서 전립선암의 발생 및 진행에 영향을 미칠 수 있는지 여부를 조사하기 위해, 16주 동안 60% HFD 식이를 급여한 비만 C57BL/6N 마우스에서 전립선의 무게 및 조직학적 구조 변화와 암관련 단백질 발현을 분석하였다. 첫째, HFD 식이를 급여한 C57BL/6N 마우스는 체중, 장기의 무게, 지방축적, 혈청지질 수치의 증가 등을 포함한 비만증상을 성공적으로 유도되었다. 전립선의 무게는 No그룹에 비해 HFD-유도 비만마우스에서 유의미하게 증가하였다. 전립선의 4가지 엽들 중 외측전립선(Dorsolateral prostate, DLP)과 정낭(Seminal vesicle, SV)의 무게는 유의적인 변화가 없었지만, 복부전립선(Ventral prostate, VP)과 전방전립선(Anterior prostate, AP)의 무게는 No그룹보다 HFD-유도 비만마우스에서 증가하였다. 또한, 전립선의 조직학적 구조에서 과형성(Hyperplasia) 및 비호지킨림프종(Non-hodgkin's lymphoma, NHL)의 발생률은 HFD-유도 비만마우스에서 유의미하게 증가하였으며, 같은 그룹에서 AP의 상피두께도 증가하였다. HFD-유도 비만마우스에서 AKT (Protein kinase B) 신호경로에서 주요 단백질의 인산화수준이 유의미하게 증가했다. 따라서 이러한 결과는 HFD-유도 비만은 C57BL/6N 마우스에서 전립선암의 발생과 진행을 촉진할 수 있음을 시사한다.
