Influence of methyl methacrylate on quantitative gel diffusion assay of immunoglobulins
Abstract:
Infection is not a common problem following implant surgery using the bone cement, polymethyl methacrylate. When infection occurs, its often disastrous results makes for major complications. Many methods have been used in an attempt to reduce bacterial contamination at the time of implant surgery, but little attention has been given to the problem of possible effects of implant materials on the immune mechanisms of the host. In the experiments reported here, the in vitro effect of methyl methacrylate monomer on human immunoglobulins was determined using a quantitative gel diffusion technique. When methyl methacrylate monomer was added to serum samples containing immunoglobulin, it caused no statistically significant change in the immunoglobulin concentration of immunoglobulin-G, immunoglobulin-A, or immunoglobulin-M. It is possible that methyl methacrylate could affect other types of antigen antibody reactions which may be important in resisting infection, but the evidence reported here indicates that in low concentrations, methyl methacrylate monomer does not affect the normal reactivity of immunoglobulins of the G, M, or A class.
Insights
Methyl methacrylate monomer, used in bone cement, did not significantly alter immunoglobulin levels in vitro. This suggests it may not impair key immune responses like immunoglobulin-G, immunoglobulin-A, or immunoglobulin-M in low concentrations.
Area of Science:
- Biomaterials Science
- Immunology
- Surgical Infection Prevention
Background:
- Bone cement, specifically polymethyl methacrylate, is widely used in implant surgery.
- While infection is uncommon, it can lead to severe complications.
- The impact of implant materials on host immune mechanisms remains under-explored.
Purpose of the Study:
- To investigate the in vitro effect of methyl methacrylate monomer on human immunoglobulins.
- To assess potential alterations in immune system components crucial for fighting infection.
Main Methods:
- Quantitative gel diffusion technique was employed.
- Human serum samples containing immunoglobulins were exposed to methyl methacrylate monomer.
- Concentrations of immunoglobulin-G, immunoglobulin-A, and immunoglobulin-M were measured.
Main Results:
- Methyl methacrylate monomer did not cause statistically significant changes in immunoglobulin-G, immunoglobulin-A, or immunoglobulin-M concentrations.
- Low concentrations of the monomer did not affect the normal reactivity of these major immunoglobulin classes.
Conclusions:
- Methyl methacrylate monomer, at tested concentrations, does not appear to directly impair human immunoglobulin-G, -A, or -M.
- Further research may be needed to explore effects on other antigen-antibody reactions relevant to infection resistance.
