[Subrenal capsule (SRC) assay as a chemosensitivity test (IV)--Evaluation of the SRC assay method as a system for growing implanted tumor-xenografts].
Using tumor specimens of human cancer serially transplanted in nude mice, we examined fundamentally the subrenal capsule assay method in order to improve the subrenal space as an area where implanted tumor-xenografts persistently grow. Host reaction in immunocompetent mice treated with cyclosporin A (CsA) (60 mg/kg subcutaneously, daily) was suppressed almost completely, and tumor-xenografts persistently grew similarly to those implanted under the renal capsule of BALB/c-nu/nu mice. CsA treatment, 30 mg/kg given subcutaneously; daily, or 60 mg/kg subcutaneously; every other day, could not suppress the host reaction. Bredinin treatment, 200 mg/kg subcutaneously; every other day, or 100 mg/kg subcutaneously; daily, could not suppress the host reaction also, and tumor-xenografts implanted under the renal capsule were rejected.
