The effect of decoction of Artemisia, Rheum, and Gardeniae in a piglet model of hyperbilirubinemia.

To find an alternative treatment for neonatal hyperbilirubinemia, the effect of a decoction of Artemisia Rheum Gardeniae was tested in an animal model. Fifteen male newborn piglets (four to six days old) were separated into three groups (five piglets/group). The animals of the first group, or Control Group, were intravenously infused with purified bilirubin (40 mg/kg) to simulate neonatal indirect hyperbilirubinemia. The animals of the second and the third groups received the decoction via oral-gastric tube feeding (Enteral Treatment Group) and intravenous injection (Parenteral Treatment Group), respectively, after infusion of bilirubin. Serum bilirubin levels were determined at 0, 0.5, 1, 2, 4 and 8 hours in these groups. The results revealed no significant effect of the decoction on hyperbilirubinemia within eight hours. The implication of this study suggests that a decoction of Artemisia Rheum Gardeniae may be not useful in the treatment of neonatal hyperbilirubinemia.
