왕겨가 Agaricus blazei Murill (AB: 신령버섯)균사체 액체배양 추출물의 항암성을 증가시키는지에 관한 연구를 수행하였다. AB균사체를 대두박을 기본으로 한 액체배지에 다양한 조건으로 배양하여, β-glucan 함량, Brix, 균사체를 측정하여 적정 생육조건을 선정하고, 이들의 열수추출물의 S-180 cell로 유도한 mouse 복수암에 대한 항암성을 조사하였다. AB균사체는 25℃에서 5일간 배양하였을 때 최적 생육을 나타내었고, 이 배양물이 다른 조건에서 배양한 배양물보다 우수한 항암성을 나타내었다. AB균사체의 생육 및 항암성은 변온배양에 따른 효과는 없었다. 따라서 이 최적배양조건(25℃, 5일 배양)에서 AB균사체를 1% 왕겨분말이 함유된 액체배지에 배양하고, 이의 열수 추출물의 항암성을 검증하였다. 1% 왕겨가 함유된 액체배지에서 배양한 열수추출물의 항암성은 왕겨가 함유되지 않은 배지의 열수추출물보다 항암성이 유의성 있게 증가되었다(p<0.05). 왕겨의 첨가는 AB균사체의 생육을 오히려 촉진시켰다. 이 결과는 왕겨가 AB균사체 뿐 만 아니라 다른 버섯균사체 액체배양물의 항암성 증진을 위한 원료로 활용될 수 있을 것임을 의미한다. The effects of rice hull (RH) powder on the anticarcinogenic activity of submerged-liquid cultures of Agaricus blazei Murill (AB) were assessed for mouse ascites cancers induced by mouse Sarcoma S-180 (S-180) cancer cells. Optimal growth of AB mycelia in the basal liquid culture medium, containing soybean meal, was achieved by culturing at 25℃ for 5 days, when evaluated by β-glucan content, Brix, and mycelial weight, relative to other culture conditions. Hot-water extract (HWE) of the submergedliquid culture of AB mycelia grown at 25℃ for 5 days exhibited a stronger anticarcinogenic activity, relative to HWE from other culture conditions. No such effects were obtained from AB mycelial cultures by alternative temperature-controlling cultures. Both cytotoxicity for S-180 cells and anticarcinogenic potentials for mouse ascites cancer of the HWE from AB mycelia grown in the basal medium containing 1% RH powder for 5 days at 25℃ were significantly (p<0.05) enhanced, relative to HWE from the AB mycelia culture of the basal medium without RH powder. These results indicate that HWE of submerged-liquid culture of AB mycelia, incubated in media containing 1% RH powder at 25℃ for 5 days, enhanced anticarcinogenic activity against S-180 cell-induced mouse ascites cancer, and suggest that RH powder is an excellent ingredient for the improvement of the anticarcinogenic potentials of the submerged-liquid culture of mushroom mycelia.

Conjugated Linoleic Acid ( CLA ) 급여가 난황의 콜레스테롤과 CLA 함량에 미치는 효과
박구부(G . B . Park),이정일(J . I . Lee),박태선(T . S . Park),김진형(J . H . Kim),신택순(T . S . Shin),강석중(S . J . Kang),하영래(Y . L . Ha),주선태(S . T . Joo) 한국축산학회 1999 한국축산학회지 Vol.41 No.1
The effects of dietary conjugated linoleic acid (CLA) on the concentration of cholesterol and CLA in egg yolk were investigated. CLA was synthesized according to the method of Alkali isomerization using safflower oil. A total of 250 hens (200 days age) were fed a control diet (a commercial laying hen feed) or CLA-supplemented diets (T1 ; 1% CLA and 4% safflower oil, T2; 2.5% CLA and 2.5% safflower oil, T3; 5% CLA, and T4; 5% safflower oil) for 6 weeks. Eggs were collected for analysis of CLA, cholesterol and fatty acid levels in the yolk. CLA concentration in egg yolk was increased by level of dietary CLA or dwation of feed. The yolk CLA concentration of T3 rapidly increased for 2 weeks, and maintained there after. On the other hand, the concentration of T4 was not significantly different from that of control during the feeding period. These results implied that CLA could not be synthesized by hen and it was necessary to supplement the diet with CLA for CLA accumulation in egg yolk. The level of CLA in egg yolk depended on the amount of CLA supplemented, and over-supplementation of CLA was not necessary. As the yolk CLA increased, the levels of cholesterol, linoleic acid and arachidonic acid decreased but that of palmitic acid increased. It was suggested that a lowcholesterol egg might be produced with over 1% CLA-supplemented diet. The concentration of CLA in egg yolk was unchanged during 28 days storage at 4℃. However, the level of cholesterol decreased during the storage.
