Embodiment Construction

[0050] Drug preparation: each bottle of lyophilized powder was dissolved with 3ml of normal saline (to restore the original concentration before lyophilization). Biosafety Examples of Drugs

[0051] 1). Acute toxicity test in mice: We selected Kunming mice aged 7-9 weeks and weighing 18-22 g. According to the pre-test common ratio of 0.8, 5 dosage groups of 50.0ml / kg, 40.0ml / kg, 32.0ml / kg, 25.6ml / kg, and 20.5ml / kg were established, with 10 mice in each group, half male and half male. After a single intraperitoneal injection, observe and record the poisoning reaction, death situation and time of the animal immediately after the drug, and observe continuously for 14 days.

[0052] 2). Rabbit pyrogen test: Select 3 Japanese white-eared rabbits with a body weight of 1.8-2.4 kg. Administration is given by 10ml / kg ear vein injection. Measure the body temperature of the anus of the rabbit at a depth of 6 cm, and then measure the body temperature once every 1 hour, a total of 3 tim...
