제충국, 멀구슬의 천적에 대한 독성을 평가하고 배추의 주요해충인 배추좀나방의 방제횟수를 결정하기 위한 시험을 수행한 결과는 다음과 같다. 포식성 천적인 이리응애류는 국제생물방제협회(IOBC) 기준으로 중간 정도의 독성을 보였으며 기생성 천적은 황온좀벌을 제외하고 비교적 안전하였다. 제충국은 1회 살포시에는 21일째부터 밀도가 떨어졌으며, 7일 간격으로 3회 살포한 경우 초기의 밀도 억제는 낮았지만 21일째에는 91.1%까지 올라가 효과를 보였다. 멀구슬을 1회만 살포한 경우 14일째까지 96.7%의 높은 살충율을 보여 주지만 이후 약효가 떨어졌다. 7일 간격으로 3회 살포할 경우 14일째부터 100%의 살충율을 나타내어 28일째까지 100%를 유지하였으며 살포방법은 멀구슬을 먼저 살포하고 제충국을 살포하는 체계가 바람직할 것으로 보인다.

This study was carried out to investigate the anti-fungal effect of Pyrethri Flos Boiled Solution (PFBS) from Chrysanthemum Cinerariaefolium Visiani on Microsporum canis, Microsporum gypseum and Trichophyton Mentagrophytes with 0.5 ml, 1ml, 2 ml. In comparative drugs, on Sabouraud's glucose agar medium to 2 ml respectively and PFBS on the rabbit skin lesions, in vivo experiments, were observed. The results obtained were as follows : PFBS slightly suppresed the growth of the fungi in 0.5 ml and markedly it in 1 ml and 2 ml. In comparative drugs, benzylbenzoate represented similar anti-fungal action in 2 ml compared with PFBS. While, salicylic acid and boric acid represented less suppression of growth of the fungi than PFBS in 0.5 ml. The effects of PFBS on the rabbit skin lesions inoculation with dermatophytes was almost normally recorved about Microsporum gypseum, Trichophyton mentagrophytes except Microsporum canis after 8 days.

Arachidonic acid(AA), which is stored in membrane glycerophospholipids, is liberated by phospholipase $A_2(PLA_2)$ enzymes and is sequentially converted to cyclooxygenase (COX) and lipoxygenase (LOX) then to various bioactive prostaglandins (PGs,) and leukotrienes (LTs). In order to find the specific inhibitors of AA metabolism enzymes such as $PLA_2$, COX-2, 5-LO and lyso PAF acetyltransferase. 195 Korean indigenous plant extracts were evaluated for their inhibitory activity on $PGD_2,\;LTC_4$ production from cytokine-induced mouse bone marrow-derived mast cells (BMMC) and arachidonic acid released from phospholipid and PAF production from lyso PAF. From this screening procedure, methanol extract of eight plants such as Saururus chinensis, Aster tataricus, Chrysanthemum cinerariaefolium, Reynoutria japonica, Disocorea nipponica, Epimedium koreanum, impatiens textori, Veronica rotunda var. subintegra were found to inhibit production of inflammatory mediators in vitro assay system.
