Abstract

Chemically derived pesticides have been used to prevent biological damage to domestic cultural property. However, their use is gradually being restricted due to the harmful effects on the human body and environment. Therefore, there is a growing interest in the search for new antifungal biopharmaceuticals whose safety has been confirmed by toxicity evaluation through animal experiments. This paper presents methods of toxicity evaluation of natural biocides using Sprague-Dawley rats and New Zealand White (NZW) rabbits. Safety of the natural biocide extract of Asarum sieboldii was evaluated using single-dose oral and dermal toxicity tests in Sprague-Dawley rats, and eye and skin irritation tests in NZW rabbits. The extract has proven antimicrobial and insecticidal activities against wood-rotting fungi and termites. After single oral administration to rats, the $LD_{50}$ values were determined to be over 4,000 and 2,000 mg/kg for males and females, respectively. After single dermal administration to rats, the $LD_{50}$ values exceeded 10,000 mg/kg for both males and females. The extract was identified to be non-irritant to the rabbit eye, and only slightly irritant to the rabbit skin. In this study, we confirmed the safety of the A sieboldii extract through animal testing. Due to the harmfulness of humidifier disinfectants, focus is on the safety of chemical pesticides, and toxicity evaluation is suggested as the basic method for hazard evaluation.

국내 문화재 생물피해 방제는 농약에서 유래한 화학적 약제를 사용하여 왔다. 그러나 인체와 환경에 대한 유해성 문제로 인하여 사용이 점차 제한되고 있으며, 새로운 방제약제의 탐색과 안전성 연구에 대한 관심이 지속적으로 증가되고 있다. 개발된 천연 생물방제제의 안전성은 동물실험을 통한 독성평가로 확인하고 있으며, 치사량과 자극성 평가를 위하여 경구독성, 경피독성, 안점막자극 및 피부자극 시험법을 이용하여 안전성을 평가한다. 독성평가를 위해 실험용 쥐와 토끼를 이용하며, 쥐에 대해 단회 경구독성과 경피독성 시험을 실시하고, 토끼에 대해 안점막자극시험 및 피부자극 시험을 시행한다. 본 시험에 이용한 천연 생물방제물질은 목재부후균과 흰개미에 대한 항진균활성 및 살충활성이 조사된 족두리풀 추출물을 적용하였다. 쥐에 대한 단회 경구투여한 결과 $LD_{50}$ 값이 수컷 4,000 mg/kg 이상, 암컷 2,000 mg/kg 이상으로 판정되었으며, 단회 경피 투여한 결과 $LD_{50}$ 값이 암수 모두 10,000 mg/kg 이상으로 판정되었다. 토끼의 눈에 대한 자극시험에서는 무자극성으로 판정되었으며, 피부에 대해서는 약한 자극성이 있는 물질로 판단되었다. 본 연구를 통해 천연 생물방제물질인 족두리풀 추출물의 안전성을 동물실험으로 확인함으로써 화학 물질의 안전성 검증을 위한 기본적인 유해성 평가 방법으로 제시하고자 한다.
