Abstract

Antimutagenic and anticarcinogenic effects of alginic acids extracted from sea mustard(SM) and sporophyII of sea mustard(SSM) were studied by Salmonella typhimurium assay system and cytotoxicity and transformation tests using C3H/10T1/2 cells, respectively. alginic acid-SM andalginic acid-SSM showed antimutagenic effects on aflatoxin B1(AFB1)and N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) in Salmonella typhimurium TA100 strain. The antimutagenic effect showed concentration dependent manner. At the 2.5mg/plate concentration , alginic acid-SSM exhibited 92% antimutagenicity against AFB1 ,while alginic acid-SM revealed 54% antimutagenictity ,s howing effectiveness of the alginic acid-SSM for the antimutagenicity. Alginic acidSSm also significantly decreased the cytotoxicity induced by 3-methylcholanthrene(MCA) and MNNG in C3H/10T1/2 cells (p<0.05). The type II and type IIItransformation foci formation by MCA and MNNG were also decreased when the alginic acid-SSM was treated, indicating that the alginic acid -SSM reduces the carcinogenesis induced by these carcinogens. The MCA-treated culture produced 10.5foci of type II +III in C3H/10T1/2 cells, however, MCA + 0.2mg/ml alginic acid-SSM treated culture formed only 1.8 foci of the types II + III in C3H/10T1/2 cells, however , MCA+0.2mg/ml alginic acid -SSM treated culture formed only 1.8 foci of the types II+ III(p<0.05). While MNNG-treated culture formed 13.0 foci, MNNG + 0.2mg/ml alginic acid -SSM treated one produced 3.0 foci of type II+III(p<0.05). These results suggest that alginic acid-SSM can effectively prevent the mutagenicities and also decrease cytotoxicity and transformation induced by some carcinogens.
