2 results about "Fish liver" patented technology

The application belongs to the technical field of biomedicine, and discloses a method for constructing a Channa argus bile stasis model. The application discloses application of rifampicin or a pharmaceutically acceptable salt thereof in construction of a fish liver injury model. The application discloses, for the first time, that the antibiotic rifampicin widely used in aquaculture is used to construct a fish liver injury model. The model is closer to the real scene of the use of a large amount of drugs when bacterial diseases break out in production practice. The injury type of the fish liver injury model is clearly directed to bile stasis, which fills the research blank of the disease model of the fish, and is different from common hepatocyte necrosis or fatty liver models.

The application discloses application of Prunella vulgaris extract in prevention and treatment of fish parasitic disease infection. Inclined tube worm in-vitro soaking experiments show that the insecticidal effect of Prunella vulgaris extract and zinc sulfate is equivalent after 48 hours, and the mortality rate is above 95.44%; based on the growth condition of rainbow trout feeding on Prunella vulgaris extract, the specific growth rate of fish is significantly improved, the growth performance is improved, and the growth of fish is promoted; the plasma biochemical indexes after parasitic infection show that the addition of 0.25% to 1% Prunella vulgaris extract in feed can significantly reduce stress caused by pathogenic stress and protect the health of fish liver.
