Linear regression analysis of the results highlighted the close relationships between doses of the medicines and mortalities of the organisms, thus providing a capability to predict toxicity effects from the dose. Toxic effects of the medicines on the ciliates were described in the present paper, and the median lethal concentrations (LC 50 values) were given. Results of measurements indicated that 2 h-LC 50 and 12 h-LC 50 values of formalin on P. coronatum were 59.00×10 -6 and 43.57×10 -6, while those of Lugol’s solutions were 90.13 and 67.84×10 -6 respectively. The tolerance of P. coronatum to formalin is apparently lower than that to Lugol’s iodine solution and potassium permanganate is a suitable medicine to kill ciliates in short time. 关键词：毒性高锰酸钾福尔马林碘酒法节肢动物冠状病毒海洋纤毛虫
