Abstract
Uremia is a common disease, the pace of development very quickly, and death rates were high. In this paper, low-temperature physics Preparation of a new cross-linked PVA microcapsules, the microcapsules good mechanical strength to overcome the current widespread use of sodium alginate - poly-L-lysine - alginate (APA) microcapsules fragile shortcomings , (APA) has completely broken microcapsules mechanical strength, the PVA microcapsules broken rate of 3 percent. Simulation of the in vitro gastrointestinal physiology can maintain stability under the conditions of the physical and chemical properties of urea, vitamins B2, and other small molecules with good permeability. Therefore, in accordance with the current treatment of uremic dialysis principle, PVA microcapsules have a very good development
