Animal experiment: |
Rats[2]Twenty male Wistar rats, approximately 6-7 weeks of age and weighing approximately 175-200 g upon receipt, are used. A total of 12 rats are dosed intramuscularly with L-(+)-Abrine at 0.63, 3.13, and 5 times the expected Abrin LD50 of 20 μg/kg. Although no toxin is used here, the concentration of the biomarker is increased by a factor of 4 to estimate an equivalent level of toxin, assuming that Labrine is present in rosary peas at a concentration four times greater that the toxin abrin. A total of 12 rats are dosed intramuscularly with L-(+)-Abrine: four at approximately 50 μg/kg body weight (bw), four at 250 μg/kg bw, and four at 400 μg/kg bw. Four control rats are dosed with water, which is the vehicle for all dosing experiments. Another four rats are dosed intraperitoneally with 20,000 μg/kg L-tryptophan to verify that endogenous L-tryptophan is not metabolized to L-(+)-Abrine[2]. |

体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
