发育异常

It is known that cardiovascular risk factors, smoking, fibromuscular dysplasia, or moyamoya disease are frequently found as an aetiological factor in patients with bilateral ICA occlusion, whereas essential thrombocytaemia, giant cell arteritis, and BD are among the very rare causes.

众所周知，双侧颈内动脉闭塞的常见病因为心血管危险因素、吸烟、纤维肌性发育不良、Moyamoya病/烟雾病/脑底异常血管网病等，而特发性血小板增多症（essential thrombocytaemia， essential thrombocythemia， ET）、巨细胞性动脉炎、白塞病则为非常罕见的原因。

Morphology of sexual reproduction abortion in'High Noon', a distant hybridization cultivar of tree peonies(P.delavayi var. lutea×P. suffruticasa), was systematically investigated with light microscopy and cross. The results indicated that:(1)The stamens matured earlier than the gynoecia and pollens dispersed at the early stage of anthesis but the rate of normal 2-celled pollens were merely 2.41%.

采用光镜和杂交等方法对牡丹远缘杂交一代品种'正午'有性生殖败育进行系统形态学观察发现：(1)雄蕊较雌蕊先成熟，初花期即散粉，正常2-细胞花粉仅占2·41%，且花粉在多种培养液中、在自身和其它两种柱头上均不萌发；柱头在谢花期大量分泌粘液，进入最佳授粉状态；(2)同一胚珠中多个大孢子母细胞减数分裂高度不同步，胚囊发育与受精延迟，部分胚乳游离核在细胞化时期分裂异常；(3)自花及品种内异花授粉不结实，天然授粉结实率为0·053‰~0·130‰。
