The purpose of this study was to investigate the understanding of immunization and antibody test by region and age. The questionnaire was conducted for those who raised their dogs for more than two years. The survey consisted of 500 people. SNS. The results showed that the perception of the reinforcement vaccination was more prevalent than Seoul / Gyeonggi province. However, in the Seoul / Gyeonggi area, the recognition and comprehension of the antibody test was higher and the participation rate by age was the highest in the 20s. In addition, the percentage of people who knew about vaccination was much higher, and the understanding of reinforcement vaccination showed a similar rate. The results of the questionnaire showed that the importance of antibody test is more important than antibody vaccination. In the case of a large number of antibodies, the reinforcement vaccination should be performed at the appropriate time after the antibody test.

본 연구에서는 차가버섯 추출물의 주름개선 화장품 원료로의 가능성을 확인하기 위하여, 차가버섯의 70 % 에탄올 추출물을 제조하여, DPPH (1,1-diphenyl-2- picrylhydrazyl) radical 소거능, 엘라스타제 저해능, MMPs (matrix metalloproteinases) 발현 저해 및 HAS-2 (hyaluronan synthase-2) 발현 저해 효능을 측정하였다. 차가버섯 추출물 및 함유성분에 대한 DPPH radical 소거능과 엘라스타제 저해 효능을 측정한 결과, 차가버섯 추출물은 농도 의존적으로 DPPH radical 소거능 및 엘라스타제 저해 효능을 보였으며(SC50 = 91 μg/mL, IC50 = 124 μg/mL), 함유성분 중 Gallic acid가 가장 우수한 결과를 나타내었다. MMPs 발현능 평가에서, 차가버섯 추출물은 5 ~ 25 μg/mL의 농도에서 50 ~ 79 % MMP-1 mRNA 발현을 저해하였으며 MMP-2의 발현량을 측정한 결과, 10 μg/mL에서 약 20 %를 감소시켰다. MMP-9의 발현에서도 5 ~ 25 μg/mL의 농도에서 54 ~ 70 %의 저해 효과를 나타내었다. 또한 HAS-2의 mRNA 발현량을 측정한 결과, 차가버섯 추출물이 전 농도에서 농도 의존적으로 HAS-2 발현량을 증가시켰다. 상기 결과를 종합해 볼 때 차가버섯 추출물은 주름개선 화장품 소재로서 개발이 가능할 것으로 사료된다.
