Abstract

This study was performed to investigate the cytotoxic effect of the Prunus mume extracts containing beverages on the growth of SNU-16 gastric cancer cell, SNU-C2A colon cancer cell, SNU-449 liver cancer cell and HeLa cervical cancer cell. The inhibitory effect on the growth of the cancer cell lines was examined by MTT(3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay, cytotoxicity test and microscopy. Also this study aimed to compare the changes of blood electrolytes and osmolarity during submaximal exercise for the intake of the Prunus mume extracts containing beverages. 20% Prunus mume extracts containing beverage exhibited the greatest inhibitory effect on the growth of SNU-16 and significantly inhibited at the concentration of $1000\;{\mu}g/mL$ in the MTT assay. Morphological changes in SNU-16 which treated with the same beverage were observed under inverted microscope. The change of blood electrolytes and osmolarity during submaximal exercise showed no significant differences between before and after intake of the beverage in both groups.

본 연구에서는 매실 추출물을 0.5%, 5%, 10%, 15% 및 20% 함유한 매실음료를 제조하여 이들의 위암, 대장암, 간암 및 자궁암 세포주 증식에 미치는 항암효과를 MTT(3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay, 세포독성 test 및 현미경 관찰 등을 통하여 조사해 보았다. 또한 12주간의 매실음료 섭취가 운동선수들의 체내 수분대사 조절 능력에 미치는 영향을 비교해 보았다. 20% 매실 추출물을 함유한 매실음료의 경우 위암 세포주인 SNU-16에 대해 증식억제 효과를 보였고, $1000\;{\mu}g/mL$ 농도에서는 유의적인 세포수의 감소를 관찰할 수 있었다. 매실음료를 배양액에 첨가하여 6일간 배양시켰을 때 SNU-16 세포주의 형태학적 변화를 볼 수 있었고 fibroblast에는 아무런 변화가 없었다. 매실음료를 섭취한 운동선수들의 경우 혈중 Na, K 및 Cl농도는 안정시에 비해서 운동 중 회복기에 유의하게(P<0.05) 증가하였으며 12 주간의 음료섭취 후 두 그룹 모두 거의 동일한 변화양상을 나타내었다.
