The invention belongs to the technical field of
biology, and particularly relates to a construction method and application of a loach
cholestasis model.The standardized loach
cholestasis model construction method is established in loaches for the first time, and the method comprises the steps that the loaches with the weight
ranging from 6.37 g to 6.41 g are selected as animal models; continuously feeding
animal feed containing 0.3 w / w%-0.4 w / w% of alpha-naphthyl
isothiocyanate, feeding for 6-8 days to obtain an
animal model, and during the feeding period, the
ammonia nitrogen content of a feeding
water body is less than 0.5 mg / L, the temperature is 24-28 DEG C, the pH is 7.4-7.6, the dissolved
oxygen content is greater than 7.0 mg / L, the
nitrite content is less than 0.05 mg / L, and one third of the
water body is replaced every day. The construction method of the loach
cholestasis model is easy to operate, the modeling rate is as high as 92.96%, the model is stable, and the detection method is multi-dimensional.
