Warfarin and scilliroside were administered orally to the wild roof rat, Rattus rattus, captured in Tokunoshima Island where the control with rodenticides was considered to have been scarcely done. Ten days' administration of warfarin resulted in LD50 of 35mg/kg and single administration of scilliroside resulted in that of 1.2mg/kg, suggesting the susceptible level to these chemicals of this species in Japan. On the other hand, the roof rats captured at several buildings in Tokyo where it has been difficult to control the species with these chemicals, were allowed to feed 0.025% warfarin powdered bait. One of the rats captured at Shinjuku survived for more than 70 days, suggesting that resistance to this rodenticide has developed in the urban area.

Trimeresurus flavoviridis (Tf) serum proteins were fractionated by anmnonium sulfate precipitation to five portions depending on the differences of its saturation percentages, that is, 0-20%, 20-30%, 30-40%, 40-50%, and 50-70%. The effects of these proteins on Tf venom-induced rat skeletal muscle damage were investigated with closer attention to histopathological features of impairment, necrosis, and regeneration ofmuscle fibers. The knowledges which portion of Tf serum proteins is effective for prevention of local lesions caused by Tf venom should shed light on the effective medical treatment after bitten by Tf snake. In consequence, it was found that the necrotic change of the rats inoculated with Tf crude venom together with the serum protein fraction of ammonium sulfate saturation percentage 40-50% was the smallest compared to those of the rats tested with other Tf serum protein fractions.

多様な固有種のいる生態系に、国際自然保護連合が「最も危険な外来種100種」に指定しているジャワマングースによる被害の出ていた奄美大島において、マングースの餌ともなる外来種クマネズミ、両種に捕食される鳥類とイシカワガエル、動物個体群に大きく影響するスダジイ堅果結実量、の動態を調べ、生態系管理の基礎情報を得た。研究成果をふまえ、国内外で外来種管理の重要性と可能性を説明した。
