古北飞虱属中国三新记录种

在整理鉴定东北地区飞虱种类时,发现古北飞虱属Jave sella Fennah,1963三个中国新记录种,其中古北飞虱J.pellucida已有文献报道在瑞典传播燕麦不孕矮缩病(Oat sterile dwarf),在欧洲、以色列传播玉米粗缩病(Maize rough dwarf),是一个值得注意的种类。 古北飞虱属全世界已知13种,均分布于古北区,其中有2种分布到新北区。本属种类体色多有变异,形态特征和雄外生殖器构造极为相似,很难确切地区分开来,故本文将其属种特征报道如下,以供鉴定时参考。

THE ORIGIN OF THE ACETYLCHOLINE RELEASED FROM THE SURFACE OF THE CORTEX

—The specific radioactivity of acetylcholine liberated from the surface of the rabbit occipital cortex has been compared with that of the underlying cortical synaptosomal and vesicular acetylcholine at varying times after the administration of [N-Me-³H]choline. Choline was administered by diffusion from solutions placed in cups formed by Perspex cylinders applied to the surface of the cortex. Acetylcholine was collected by diffusion into these cups. The specific radioactivity of the acetylcholine declined progressively. The effect of stimulation of afferent cholinergic pathways was to cause a fall in the specific radioactivity of the released acetylcholine. However this was always higher than that of the synaptosomal or vesicular acetylcholine as represented by fractions P₂ and D of the authors’fractionation scheme. It is concluded that acetylcholine released from the cortex must come from a store or stores more recently synthesized than the endogenous acetylcholine of these subcellular fractions.
