沈阳地区气传致敏花粉探讨

本文报道在沈阳地区1965—1985年间于空气中间断收集大气花粉5年,共收花粉玻片1100张,花粉45780粒,属于24科37属或种。其中9种(或属)超过千粒,为优势种类花粉。每年沈阳市大气中花粉出现两个高峰,一个为春季(四、五月),另一个为夏秋季(七八月)。通过长期观察发现,花粉种类和数量每年虽有不同,伹差异不大,唯有豚草花粉消长明显。大气中花粉种类及数量的变化往往受到气温、国家有关绿化政策以及社会风气的影响。花粉与过敏症关系十分密切,我们采用17种花粉制成浸液为病人皮试和治疗。皮试结果阳性率最高的为蒿属花粉,其次为其它夏秋花粉,春季花粉阳性率不高,致敏性不强。用花粉浸液对过敏症者进行免疫治疗,收到一定的疗效。

A STUDY ON THE AIRBORNE AND ALLERGIC POLLEN IN SHENYANG

A total of 1100 slides containing 45780 airborne pollen grains belonging to 24 families and 37 genera or species were made intermittently for 5 years from 1965 to 1985.Among them there are 9 dominant species with more than 1000 pollen grains in each species.There are 2 peaks of airborne pollens in the atmosphere of Shenyang,one is in Spring (April and May),the other is in Summer and Autumn (July and August).By means of intermittent collection and observation in the past 20 years,it is found that the airborne species and amount of pollen grains are variable,indistinctive,except that Ambrosia L.is significantly.Usually,they vary with the Changes of temperature,national policy for ornamental planting and social hobby.Pollen grains are closely related with allergic diseases.Fluid extracts of 17 species of pollens have been used for skin test and therapy.The fluid extract of Artemisia L.pollen gave the highest rate of positive reaction for skin test,that of the summer-autumn pollens rated the second and that of the spring pollens is the lowest one.Some good results have been obtained by using the fluid extracts of pollens for treatment of allergic diseases.
