The bronchial tree and lobular division of the gorilla lung

The bronchial ramification in one specimen of gorilla lung was examined from the viewpoint of comparative anatomy, on the basis of the fundamental structure of bronchial ramification in the mammalian lung (Nakakuki, 1975, 1980). The right lung of the gorilla consists of the upper, middle, lower, and accessory lobes. The right lung has the dorsal, lateral, and ventral bronchiole systems, but the medial bronchiole system is lacking. The upper lobe is formed by the first branch of the dorsal bronchiole system. The middle lobe is formed by the first branch of the lateral bronchiole system. The accessory lobe is formed by the first branch of the ventral bronchiole system. The remaining bronchioles constitute the lower lobe. The left lung consists of the middle and lower lobes; the upper and accessory lobes are lacking. The left lung has the dorsal and lateral bronchiole systems, but the ventral and medial bronchiole systems are lacking. The middle lobe is formed by the first branch of the lateral bronchiole system. The remaining bronchioles constitute the lower lobe. The bronchial ramifications of the gorilla lung are rather similar to those of the human lung.

Embryological Studies of Codonopsis pilosula Nannf.

This paper reports the studies of megasporogenesis and microsporogenesis, development of female and male gametophytes, fertilization, and development of embryo and endosperm, The anther wall consists of four layers, i.e. epidermis, endothecium, middle layer and tapetum. Part of the tapetum cells originates from the primary parietal cells, and the other part comes from the basic tissue of the anther partition. Tapeta? cells are uninucleate or binucleate, and belong to the secretory type. Microsporocyte originates directly from the primary sporogenous cell, Cytokinesis is of the simultaneous type. Arrangement of microspores in tetrad is isobilateral. Mature pollen grain is of the 2-celled type. The ovary is tricarpellum, trilocular with many ovules. The ovule is mono-integinous, tenui-nucellar and anatropous. The embryo sac originates from the single-archesporial cell. The one chalazal megaspore in linear tetrad is the functional megaspore. The development of embryo sac is of the Polygonum type. Before fertilization, two polar nuclei fuse in to a secondary nucleus and the antipodal cells degenerate. Fertilization is porogamy, fusion of one sperm with secondary nucleus is faster than that of one sperm with egg nucleus. The development of endosperm is of the cellular type. The first three divisions of endosperm ceils are regular. Two endosperm cells near the ends of chalaza and the micropyle develop into haustorium without division. The haustoria gradually degenerate at the late stage of globular embryo. The mature seeds contain abundant endosperm. The development of embryo is of the Solanad type. The suspensor consists of 12–20 cells. The optimum development of the suspensor is at the early stage of the globular embryo. It begins to degenerate after late globular stage. The embryo develops from proembryo, heartshaped embryo, dicotyledenous- to mature embryo.     

濒危植物瑶山苣苔的大小孢子发生和雌雄配子体发育研究

利用石蜡切片技术对瑶山苣苔大小孢子发生、雌雄配子体发育及胚胎发育进行了细胞学观察,结果表明:瑶山苣苔胚珠倒生,单珠被,薄珠心,具珠被绒毡层。大孢子母细胞减数分裂形成的四分体呈直线排列,合点端的大孢子发育为功能大孢子,其余3个大孢子退化,胚囊为单孢子发生的蓼型胚囊发育方式。花药为四囊形,花药壁由外到内依次为表皮、药室内壁、中层和腺质绒毡层,小孢子形成时胞质分裂为修饰性同时型,小孢子四分体排列方式为四面体形,成熟花粉为2核细胞。胚乳发育为细胞型,在胚的发育过程中被吸收耗尽。瑶山苣苔大小孢子发生和雌雄配子体发育基本正常,不是导致其濒危的原因。但瑶山苣苔果实成熟时,胚仅发育至球形胚时期,需要经过一定时间休眠才能完成形态后熟,表明胚未发育完全可能是该物种天然更新困难的原因之一。     

象牙参种子的解剖学和组织化学研究

象牙参种子解剖学和组织化学的研究结果表明, 种子包括假种皮、种皮、外胚乳、内胚乳和胚。假种皮没有完全包被种子, 由约4~5 层薄壁细胞构成。种皮可以分为外种皮、中种皮和内种皮。外种皮由1 层表皮细胞构成, 细胞壁明显增厚;中种皮包括下皮层、半透明细胞层和3~4层细胞的色素层, 下皮层和色素层细胞均充满红棕色色素;内种皮由1 层体积小、壁局部增厚的砖形薄壁细胞构成。种子在珠孔端分化出珠孔领、孔盖和种阜状结构, 珠孔领为同形型, 孔盖不具石细胞硬层。合点区内种皮出现缺口, 缺口间充满合点区色素细胞, 其整体轮廓成新月形。外胚乳可分为厚区与薄区两部分, 外胚乳细胞壁平直, 细胞内充满淀粉。内胚乳细胞主要含蛋白质, 也有少量脂类物质, 细胞界限不清楚。胚棒状, 两端略膨大, 含大量脂类物质, 也含蛋白质和多糖。
