Abstract

Purified salt and several different types of sea salts showed comutagenicity in the presence of MNNG (N-methyl-N'-nitro-N-nitrosoguanidine). However, the salts exhibited anti-cancer effects in HCT-116 human colon carcinoma cells and AGS human gastric adenocarcinoma cells. Sea salt showed less comutagenicity effects than purified salt. French sea salt (Salines de Guerande) and Korean sea salt I, which contained higher levels of minerals, showed less comutagenicity. In MTT assay, when HCT-116 and AGS cancer cells were treated with the salts, French sea salt (36% and 34%) and Korean sea salt I (35% and 33%) showed higher anticancer activities than Spanish sea salt (33% and 31%), Italian sea salt (29% and 27%), Korean sea salt II (22% and 22%), or purified salt (18% and 15%) at a salt concentration of 1%. French sea salt and Korean sea salt I also showed better anticancer activities than the other salt samples at a low concentration of 0.5% (p<0.05). Apoptosis related genes of Bax and Bcl-2 were regulated by the treatment of the salt in the colon cancer cells. French sea salt and Korean sea salt I especially increased Bax mRNA expression, but decreased Bcl-2 expression, indicating that they can induce apoptosis of the cancer cells. From the experimental results, sea salt showed better health functional effects than the purified salt, and French sea salt and Korean sea salt I which contained high levels of Ca, K, and Mg showed better effects.

국내산 정제염, 천일염과 유럽산 천일염 등의 SEM에서의 형태, 무기질 성분, 보돌연변이와 암세포 in vitro 항암 기능성을 측정하였다. 정제염은 SEM을 이용한 관찰 시 구조가 규칙적이었고 천일염은 불규칙한 표면 구조를 가지고 있었다. 천일염의 크기도 차이가 있었고 프랑스 천일염과 한국천일염I은 다른 천일염보다 크기가 작았다. 무기질 함량은 프랑스 천일염과 한국 천일염I이 Ca, K, Mg 등의 함량이 다른 소금보다 더 많았다. pH도 프랑스 천일염과 한국 천일염I이 가장 높았다. 한국산 두 가지의 천일염은 무기질 함량에 따라 물리적 특성의 차이를 보였고 한국 천일염I은 프랑스 천일염과 비슷한 무기질 함량을 가지고 있었다. 소금은 보돌연변이 효과가 있었지만 특히 무기질 함량이 높았던 프랑스 천일염과 한국산 천일염I은 다른 소금보다 낮은 보돌연변이 효과를 나타내었다. HCT-116과 AGS 암세포에 대한 in vitro 항암 효과에서도 보돌연변이 효과와 비슷한 경향을 나타내었고 많은 무기질을 함유한 프랑스 천일염과 한국산 천일염I의 암세포 성장 억제효과와 암세포의 apoptosis 유도 효과가 가장 높았다. 이상의 결과로부터 소금의 기능성은 무기질 함량이 많은 천일염이 정제염보다 좋으며 천일염 중에도 Ca, K 등의 무기질 함량이 높을수록 기능성도 증가하는 것으로 나타났다.
