摘要：

On the basis of the concentration of unconjugated bilirubin and available albumin for the binding of bilirubin it is possible to calculate the level of unbound bilirubin in a serum sample. The solubility of bilirubin can further be calculated when the pH is known. In cases of threatened kernicterus the free bilirubin concentration in serum samples from newborn infants surpasses the solubility by a factor close to one hundred. It is hypothesized that deposition of bilirubin in tissues takes place as an ongoing event, the deposited pigment being eliminated by bilirubin oxidase in healthy infants. Kernicterus results when the rate of deposition becomes overwhelming as a result of high bilirubin concentration, low albumin reserve, low pH, after administration of a displacing drug, or if the bilirubin oxidase system has been compromised by preceding birth asphyxia or other forms of central nervous system injury.
