✦ Synopsis
This brief communication describes the immunocompetent activity of the Chinese folk-medicinal herbs, Hedyotis corymbosa, H. diffusa and Mollugo pentaphylla in mice after moderate whole body x-irradiation. These antitumour drugs, given at doses of 500 and 1000 mg/kg/day for 7 consecutive days before x-irradiation protected ICR strain mice from the sublethal effects of radiation at a dose of 4 Gy, especialy for the dose at 1000 mg/kg. Prior administration of H. corymbosa and H. diffusa ameliorated the leukopenia and splenic cellular decrease induced by sublethal irradiation, and slightly increased the immunocompetence of splenic cells after being stimulated by mitogens. However, administration of M. pentaphylla before x-irradiation exerted a less protective effect on ameliorating leukopenia and on splenic cellular immunocompetence. These findings suggest that some types of Peh-Hue-Juwa-Chi-Caoi (PHJCC) may also be effective in the prevention of haematopoietic damage when used in combination with radiotherapy.
