新西兰银杏种质资源研究

新西兰位于南半球太平洋南部,介于南极洲和赤道之间,是目前为止南半球唯一一个将银杏作为产业来发展的国家。银杏在新西兰已有100多年的栽培历史,其南岛和北岛的各个城市和地区均栽植有银杏,但主要用作庭院、公园、街道绿化树种零星种植,直到21世纪初才开始被作为一种产业来发展。通过对新西兰的Auckland,Wellington,Hamilton,Hastings等主要城市的银杏种质资源进行广泛调查和定点观测,结果只发现有梅核类、佛指类、马铃类、园子类等四种类型。种核也较小,最大的为2.15g,最小的仅1.44g。本文主要报道了银杏在新西兰的栽培历史、生物学特性、种质资源及发展现状等,以期为中新两国开展在银杏方面的合作提供相关信息。

Delayed intra-tumoural haemorrhage in pineal germinoma: Case report and review

Intraparenchymal haemorrhage in a pineal germinoma is a very rare, though clinically significant event. We report the first case of a significantly delayed intraparenchymal haemorrhage in a pineal germinoma, 14 days after endoscopic third ventriculostomy (ETV), causing precipitous patient deterioration. We discuss potential contributing pathophysiological factors, and seek to illustrate that knowledge of its occurrence, and associated morbidity, is clinically significant in managing pineal germinoma patients with acute deterioration post obstructive hydrocephalus CSF diversion.
