  1. Israelensis recombinants, which contained recombinants plasmid pmt4 and pmt9 respectively, were obtained by electroporation. the bioassay results showed that the recombinants b - pmt9 and b - pmt4 had toxicities both to resistant and susceptible c. quinqnefasciatus larvae during vegetative growth stage, having the lc ? o values similar to that of. fi. sssii - 1. however, the toxic levels of the final sporulated cultures of recombinants b - pmt4 and b - pmt9 differed, with a lcso value of 2 49mg / ml for b - pmt9 and little toxicity for b - pmt4 by using the plasmid pmt9, m txl gene from b. sphaericus was ligated with p20 and cytjaa gene, giving recombinant plasmid pmpx2

    含有pmt9和pmt4的大腸桿菌轉化子能表達產生mtx1毒素，發酵液對敏感和抗性致倦庫蚊幼蟲具有中度毒殺作用；含有pmt9和pmt4的蘇雲金芽孢桿菌轉化子b - pmt9和b - pmt4在營養體生長階段對敏感蚊幼和抗性幼蟲也具有毒性，毒力與野生型b . sss - 1相當，而不同轉化子在芽孢形成期的毒力因插入的mtx1基因轉錄方向不同而表現出差異，其中b - pmt4對目標蚊幼毒力極低（ lc _ （ 50 ） 10mg ml ） ，而b - pmt9對蚊幼蟲具有毒性（ lc _ （ 50 ） = 2 . 49mg ml ） 。
  2. The hematoporphyrin sensitizer used in photodynamic therapy produce toxic substance through translating energy to oxygen molecule, so the distribution of oxygen in tissue have special value as there has consumption of oxygen during photodynamic therapy

    光動力療法使用的葉琳類光敏劑主要是通過將能量轉移到氧分子產生單線態氧來產生毒性物質，因此在光動力治療中有氧的消耗，使組織中氧分佈對光動力作用具有特殊意義。

  4. It meaned that simulated acid rain made the toxic effects of zn or cd on growth of the plants more serious. the fresh weights and chlorophyll contents of phaseolus vulgaris l were the highest when ph value of acid rain was 4. 5, zn concentration was 60 mg / kg, and or cd concentration was 0. 5 mg / kg. this showed that lower acidity of simulated acid rain and lower concentrations of zn or cd could promote growth of the plants

    本試驗中，酸雨加zn或者酸雨加cd使小白菜鮮重小於單一污染處理，說明酸雨增加了zn 、 cd對小白菜的毒害作用；而當酸雨ph值為4 . 5 、 zn濃度為20mg / kg或cd濃度為0 . 5mg / kg時，四季豆鮮重達到最大值，這表明低強度的酸雨和低濃度的zn 、 cd促進四季豆的生長。
