摘要
本文选用微量组胺测定技术，对中华硬蜱（Ｉｘｏｄｅｓｓｉｎｅｎｓｉｓ）雌性成虫叮咬初次和再次感染宿主（家兔）血液和局部皮肤组织中组胺含量进行测定。研究结果表明：中华硬蜱初次叮咬家兔后吸血量２３３．７８±４０．５３ｍｇ，宿主血液和局部组织中组胺含量第５天达高峰，分别为４０５．４４±１２０．２９ｎｇ／ｍｌ和３６２．３４±８４．７２ｎｇ／ｇ，而中华硬蜱再次叮咬感染组家兔吸血量为９６．４２±３６．２８ｍｇ，宿主血液和局部组织中组胺迅速升高，２４小时达高峰，分别为６４２．４３±１４６．４７ｎｇ／ｍｌ和１１５２．５３±２０３．９６ｎｇ／ｇ，与初次叮咬组胺含量相比有显著性差异（Ｐ＜０．０１）。提示组胺与宿主产生对蜱感染的获得性抵抗力有关。
Using micro determination technology, the histamine content in blood and attachment site of adult female Ixodes sinensis was determined after first and scond infestation of rabbits. The result showed that the engorgement weight of I.sinensis after first infestation was 233 28±40 53mg, histamine content in blood and local tissue of the host arrived the highest at the 5th days, being 405 44±120 29ng/ml and 362 34±84 72ng/g respectively. the engorgement weight of I.sinensis after second infestation was only 96 42±36 28mg. The histamine content in blood and local tissue arrived the highest after 24 hours, being 642 43±146 47ng/ml and 1152 53±203 96ng/g respectively, showing significant difference from that after the first infestation (P<0.01). It is suggested that the histamine content of the host is related to the acquired resistance after Ixodes sinensis infestation.
