식품재료인 메주와 다시마 그리고 이들 재료를 사용하여 자연발효에 의해 제조한 전통 막장에 대한 일반성분을 분석한 결과 기존의 막장에 비해 무기물의 함량이 증가하였다. MNNG에 대한 항돌연변이 효과(400$mu$g/plate)에서 S. typhimurium TA100 균주에 대해 다시마 분말 5% 첨가 막장이 다른 첨가 농도보다 높은 95.0%의 강한 억제효과를 나타내었다. 4NQO에서도 5%의 다시마 분말을 첨가한 막장이 TA98과 TA100 두균주에 대해서 400$mu$g/plate에서 각각 81.4%와 88.8%로 다른 첨가 군보다 높은 억제효과를 나타내었다. B($alpha$)P에 대한 억제효과에서는 동일농도에서 TA98, TA100 두균주에 대하여 다시마 분말 5% 첨가 막장이 각각 85.3%와 91.0%로 다른 첨가군보다 높은 억제활성을 나타내었으며, Trp-P-1에 대해 두균주에 대해서는 96.5%와 92.0%로 다른 농도보다 높은 억제효과를 나타내었다. 암세포 성장 억제효과를 검토한 결과에서는 5%다시마 분말 첨가 막장이 1.0mg/ml시료농도에서 A549가 61.2%, KATOIII는 61.8%, 그리고 HepG2는 66.8%의 성장억제 효과를 나타내었다.
This study was carried out to investigate antimutagenic and cytotoxic effects of Korean traditional Mackjang added with sea tangle powder. The content percentage of most of minerals among general composition increased by adding sea tangle powder. By the Ames test, the antimutagenic effect of ethanol extract of Korean traditional Mackjang added with 5% sea tangle powder was strongest exceeding the control, 10%, and 15% sea tangle additions. The ethanol extract (400$mu$g/plate) of Mackjang added with 5% sea tang1e powder in the S. typhimurium TA 100 strain showed inhibition rate of 95.0% against the mutagenesis induced by MNNG. The inhibition rate of ethanol extract (400$mu$g/plate) of Mackjang added with 5% sea tang1e powder in the S. typhimurium TA98 and TA100 strains was 81.4% and 88.8%, respectively, against the mutagenesis induced by 4NQO. Under the same conditions, the suppression against B($alpha$)P and Trp-P-1 in the TA98 and TA100 strains were 85.3% and 91.0%, and 96.5% and 96.5%, respectively. For the anticancer effects, an investigation was done on the cytotoxicity of Mackjang added with 5% sea tangle powder on the cell lines with human lung carcinoma (A549), human hepatocellular carcinoma (HepG2), and human gastric carcinoma (KATOIII). The cytotoxicities were inhibited with increasing the extract concentration. The treatment of 1.0 mg/mL Mackjang added with 5% sea tang1e powder showed relatively strong cytotoxicity of 61.2%, 61.8% and 66.8% against A549, KATOIII, and HepG2, respectively.
