한약박 및 유기셀레늄이 체내 중금속 축적도에 미치는 영향의 모발 분석과 혈액 및 장기 분석 간의 상관도 연구

This study was carried out to develop a method for decreasing the heavy metal composition of living stock. Sprague-Dawley (SD) male rats were pre-treated with heavy metals administered i.p. at the limits of regulation according to the feed CODEX in Korea. Herbal medicine remnant was administered p.o. (2, 4 ppm of average feeding amount) for the entire period of study with organic selenium (2 ppm of average feeding amount) before any other treatment. 2,2`-azobis(2-amidinopropane) dihydrochloride (AAPH) was also administered i.p. in a single dose of 60 mg/kg body weight before animals were sacrificed. The TBARS test with the FOX assay demonstrates a decrease of heavy metals due to these functional materials in vitro. Moreover, this decrease in heavy metals was also demonstrated by in vivo tests based on SD rats hair analysis and organ analysis after 6 weeks. A good linear correlation between hair analysis and organ analysis represented by liver and blood was shown. The present findings suggest that measurement method of heavy metal composition using hair analysis for healthy livestock can be used in place of detection methods carried out by organ and blood analysis, and herbal medicines with organic selenium may be very effective at decreasing heavy metals of feed materials in feed manufacture industry.
