MG virus
3.With the prolongation of acting time of drug,the inhibitive effect of chinonin against influenza virus A weakened at low concentration, and it basically kept no change at high concentration not less than 1.4 mg·ml? -1. Also, chinonin had remarkable capacity to decrease the infectivity of influenza virus A.
4.Methods: 50 Guangzhou brown spot ducks were used in this experiment. After the ducks were infected DHBV, they were divided into four groups at random(ACV 200 mg/kg group, Yu Gan capsules 6.5 g/kg group, Yu Gan capsules 3.25 g/kg group and virus control group) and Drugs were given by stomach once a day.
5.4) Adding 3-5mg/L 6-BA or 500mg/L CCC to the medium, keeping it 8 hours in light and 16 hours in darkness every day could obviously improve microtuber production5) Up to over 95% of virus-free seedlings could survive when the seedlings with a length of 8cm were put into the air at 20℃ for 2 days.
7.WSSV(white spot syndrome virus) is isolated from infected crayfish cambarus clarki. , by different speed centrifugation , sucrose cushion , sucrose gradient centrifugation. Quantified by Bradford methods, the concentration of WSSV is 0.912mg/ml.
9.It was showed from the anti virus experiment in vitro that 8mg crude drug/ml of Guizhi decoction could inhibit cytopathy induced by 10 strains of viruses associated with respiratory infection at the different extents.
