โฆ Synopsis
Currently, the use of silicone-filled devices, mainly in plastic surgery for breast reconstruction or augmentation, is being debated by the scientific community in connection with the risk to the patient. In this study the response of whole blood or isolated peripheral blood lymphocytes from patients with silicone-gel-filled breast implants was assessed in vitro, in order to verify the hypothesis of silicone material acting in vivo as a sensitizing agent. Both quantitative and qualitative changes of lymphocyte subpopulations of patients carrying silicone devices were assessed and compared with healthy subjects. Upon 24-72 h in vitro re-exposure of patients' lymphocytes to silicone extract, lymphocyte surface antigen expression was monitored by flow cytometry, and the functional response of lymphocytes was measured by radioactive tracer uptake and biochemical changes.

Cultures of human tonsil lymphocytes were exposed in a Crawford cell to a 450-MHz field (peak envelope intensity 1 .O mW/cmz), sinusoidally amplitude modulated (depth 80%) at frequencies between 3 and 100 Hz for periods up to 60 min. The Crawford cell was housed in a temperature-controlled chamber (
An in vivo-in vitro test system with high sensitivity to teratogens has been developed and validated. A single acute intra-peritoneal injection of teratogens (1 8) and non-teratogens (13) was administered to pregnant rats on the 12th day after fertilisation, and uteri were removed after 16 h by lapa
