唾液中A、B、H血型物质的定量研究

Quantitative Investigation of Blood Group A, B, and H Substances in Saliva

以人工合成血型物质作为标准参照物质，应用时间决定性荧光免疫测定法（ＴＲ－ＦＩＡ）测定了１２９例个体唾液中的Ａ、Ｂ、Ｈ型物质含量。其由检出感度以下到４．１６ｍｇ／ｍｌ的范围内呈现连续分布趋势。分泌型的血型物质含量明显高于非分泌型，非分泌型的一部分也检出少量血型物质。Ｏ型的Ｈ物质明显高于Ａ、Ｂ、ＡＢ型，并在Ａ、Ｂ、ＡＢ型个体内与Ａ、Ｂ型物质的含量呈正相关。

We applied time resolved fluorotris immunoassay (TRFIA) to the quantitative detection of the content of A, B, and H substances in saliva with artificially synthesized A, B, and H Substances as control. The quantity of the blood group substances could be used toclassify an individual as a secretor or a nonsecretor. The quantity of H substances was obviously higher in type O individuals than that in A, B, and AB type individuals, and was positively correlated with the quantity of A and B substances in each type.
