| Research Abstract |
This study aimed to verify a hypothesis that recent increase of allergy patients is partly explained by antibodies against plastic resin materials. A new method to detect serum antibodies against plastic resin materials were developed by using western-dot blotting. Among 100 wonlen, the positive rates of IgG against phthalic anhydrate and glutaraldehyde were very high. That against toluene 2,4-diisocyanate was around 50%, and those against bisphenol A diglycidyl ether, P-henylenediamine and formaldehyde were very low. The antibody titers against the causal chemical were related to the severity of allergies. From this study, it is suggested that antibodies against plastic resin materials related the onset of allergies.
