高原地区病理妊娠弓形体感染的分布调查研究

应用微量间接血凝法（IHA），对289例高原地区（海拔2260米）病理妊娠和正常妊娠孕产妇血清中弓形体抗体进行了检测与分析。结果表明：藏族理妊娠孕产妇血清的弓形体抗体阳性率较高（10.16％），但在藏、回、土、汉四民族间病理妊娠弓形体抗体阳性率差别无统计学意义（X2=0.3295，P＞0.05）；农民病理妊娠孕产妇血清的弓形体抗体阳性明显高于干部、工人及其它职业者，其差别有统计学意义（X2=9.47，P＜0.05）。提示高原地区孕产妇弓形体感染的民族和职业分布较广，应加强产前检查和及时治疗，以达到优生的目的。

INVESTIGATION INTO THE DISTRIBUTION OF PATHOLOGIC PREGNANCY TOXO-INFECTION IN THE PLATEAU AREA

With micre-indirect- hemagglutination (IHA ), the authors test 289 cases of serum toxoplas- antibody of pathologic pregnancy gravida and puerpera in plateau area(2 260 a. s. l). Results: The positive incidence in Tibetan is rela tively higher(10. 16% ), but not statistical difference be observed betwen four nationalities of Tibetan, Hui, Tu and Han(x2 = 0. 3295, p > 0 .05). However the positive incidence in pent is apparently higher than in cadre and worker, ect., showing the statishcal meaning (x2 = 9 .47, p < 0 .05 ). Display: In plateau area the distribuhon of gravida and puepera toxoplas-in fection is fairly high among different nationalities and professions; so the prenatal examination and immediale treatment should be strengthened, for the goal of aristogensis being attained.
