RESULTS: Microscopically, the lesion consisted of abundant collagen fibrils, proliferated histiocytes and numerous infiltrated plasmocytes, lymphocytes and eosinophilic granulocytes. Fusiform or polygonal histiocytes had abundant, granular, eosinophilic cytoplasm or clear cytoplasm containing radially oriented strands or resembled xanthoma cells. Emperipolesis of numerous small lymphocytes was seen in the cytoplasm of some large histiocytes.

结果： 镜下可见丰富的胶原纤维和组织细胞增生以及大量浆细胞、淋巴细胞和嗜酸粒细胞浸润，组织细胞呈梭形、多边形，胞质嗜酸性颗粒状、放射条纹状或泡沫状，一些大组织细胞质内有多量小淋巴细胞。

It is the first time that these phenomena were observed: Two nuclei are surrounded by plasma and locate at the central of the female gametophyte and the others nuclei are positioned at the fringe of the female gametophyte; Before the pollen tube enters the female gametophyte. the nuclei in chalazal end begin splitting of plasma and form multinuclear cell.4. The pollens of Gnetumc are spherical or applanate with single aperture. The ornamentation of exine is spine. The basis part of spine is lenience and the top part of spine is tip or obtuse sphere.

首次在买麻藤属植物的雌配子体中观察到2个游离核位于配子体的中央位置，且被一团原生质所包围的，其余的游离核位于边缘的现象以及花粉管进入雌配子体前，合点端的核已经发生胞质分裂形成多核细胞的现象 4、买麻藤的花粉近球形或扁平型，有单萌发孔，外壁表面具小刺状纹饰，小刺基部宽大，末端尖或钝圆。

The location and structures of sex-pheromone-producing gland in female H.insularis were studied by EAG,GC,SEM,and TEM.These studies showed that thegland situate in the intersegmental membrane between the eighth and ninthabdominal segments,and is an eversible abdominal fold;Many plump cones disturbon the surface of the gland.The glandular cells of 2-day old virgin female H.insularis are arranged in one layer,among which the central cells are columnarepithelial cells and flat on two sides.The nucleus is irregular elliptical.There isevident conjugation between cells and the involution is more in the basal membraneof cell.Microvilli are distributed on the cytoplasmic membrane and linked withendocuticle on which there are many layers of chitin,and the outer cuticule is staineddeeper.The cell contains bubbles,mitochondria,glycogen deposits,roughendoplasmic reticulum and smooth endoplasmic reticulum.

结合触角电位、毛细管气相色谱、扫描电镜、透视电镜等技术对小线角木蠹蛾雌蛾腹尖末端不同组织部位提取物的测定分析以及腺体位置和形态结构的观察发现：小线角木蠹蛾性信息素分泌腺位于腹部末端8～9节之间，是一个由节间膜特化而成的上皮结构，为一可外翻的腹褶，腺体表面分布着饱满的锥形体，羽化后2天未交尾的雌蛾腺体细胞呈单层排列，腹面中央由密集的柱形上皮细胞组成，细胞排列向两侧延伸至背部，其形状由柱形逐渐变为扁平形，细胞核为椭圆形，细胞与细胞间有明显的胞连接，细胞基底膜基褶较多，质膜上分布着微绒毛，并与内表皮连接，内表皮上有多层几丁质，外角质层染色较深，细胞质中含有空泡、线粒体、脂质粒、粗面内质网和光面内质网。
