[Antigenicity study of T-3761].
Antigenicity studies of T-3761, a new quinolone derivative, were conducted and the following results were obtained. 1. By active systemic anaphylaxis test in guinea pigs, neither immunogenicity nor allergenicity of T-3761 was noted. 2. By homologous 4-hour passive cutaneous anaphylaxis (PCA) test using the serum obtained from these guinea pigs, neither immunogenicity nor allergenicity of T-3761 was noted. 3. The potential of IgE antibody production in mice was examined by heterologous 24-hour PCA test in rats. But neither the potential of IgE antibody production nor allergenicity of T-3761 was noted. 4. By passive hemagglutination assay, we analysed the antibody titer in rats and dogs serum obtained from three-month toxicity repeated dose studies (oral and intravenously administration). But the hemagglutination response was negative and specific antibodies were not detected.
