Abstract

The objective of this study was to obtain data on safety-in-use of yeast hydrolysate with a molecular weight of 10~30 kDa as a dietary supplement by assessing its subacute oral toxicity in ovariectomized rats. Yeast hydrolysate did not produce mortality or significant changes in general behavior or gross appearance of internal organs of rats. There were no significant differences in organ weights between control and yeast hydrolysate groups. Hematological analysis and blood chemistry revealed no toxic effects of yeast hydrolysate. Neither gross abnormalities nor histopathological changes were observed. These results show that yeast hydrolysate possesses very low toxicity as indicated in a postmenopausal animal model.

본 연구에서는 갱년기 완화 연구에 앞서 처치 대상자를 폐경 이후로 한정하여 난소절제를 통해 폐경을 유도한 암컷 흰쥐를 대상으로 효모 가수분해물의 안전성 평가를 하였다. 효모 가수분해물을 8주 동안 아급성 처치한 후 관찰한 결과 갱년기 모델 쥐에서도 건강한 쥐와 마찬가지로 이전 연구와 같이 효모 가수분해물은 체중, 식이 섭취를 비롯해 임상적 소견과 혈액 생화학적 분석, 그리고 장기 무게 및 조직 병리학적 분석에서 안전한 것으로 평가되었다. 이에 효모 가수분해물은 폐경기 동물 모델에서 아급성으로 처치 시 독성을 일으키지 않는 것으로 생각된다.
