Methods for detection and control of cancer encompass a large area of today's research. Recent use of granulomas as a model for such detection and control may be a promising field, especially for monitoring tumor antigens and immune responses. These granuloma systems are increasingly becoming vehicles in the study of tumor immunology. Although granulomas may be induced naturally by means of foreign bodies i.e. viral, fungal, or bacterial agents, new methods are being established to produce artificial granuloma systems. These systems include chemical or foreign body implantations followed by tumor vaccine challenges.The research presented here involved the use of a golf ball-induced granuloma for the purpose of establishment of a detection system for immune responses. The use of a golf ball-induced granuloma provided a closed system for monitoring cell-mediated and humoral responses to tumor antigens. Immune responses were monitored by means of hematocrits (packed blood cell counts), white blood cell differential counts, and electrophoretic results.Hematocrit results indicated no great immune response to the closed vaccine injected granuloma systems. Observations made on differential white blood cell counts indicated decreasing neutrophil/lymphocyte ratios for cellular immune responses. Electrophoretic results for granuloma fluids indicated decreases in albumin levels concurrent with increases in peak two, and complete loss of peak three following vaccination. Responses to tumor specific antigens in the form of cell-mediated immune responses are indicated by the results presented in this research. Utilization of the golf ball-induced granuloma system provided a means of separating the cell-mediated and humoral immune responses.Tumor specific antigens elicited various immune responses and provide hope for future identification of tumors by this method. Future development and utilization of the golf ball-induced granuloma system may be potential means of monitoring cell-mediated immune responses to tumor malignancies.
