XI. BIOCHEMISTRY OF CEMENT. Based on biochemical analyses of cement, the main amino acids present are leucine, serine, tyrosine and glycine, but only low concentrations of histidine and methionine are present Kemp et al., 1982. Due to the fact that the cement cannot be easily dissolved, protein identification is very difficult.
This study was conducted to assess the immunomodulatory potentials immunoglobulin E IgE, interferon-gamma IFN-ampgamma and tumor necrosis factor-alpha TNF-ampalpha of cement dust in individuals occupationally exposed to cement. Potentials of cement particles to modulate immune responses have not been documented in occupationally exposed Nigerians. Twenty-nine male cement
