The present paper deals with the observations on embryo sacs (ES) isolated by enzymatic maceration in four Campannlaceous species, Platycodon grandiflorum, Adenopora axilliflora, A. tetraphylla, Codonopsis lanceolata. Fixed ovules were macerated in a mixture of pecti nase and cellulase. The mature were cleared with lactophenol for mopholgical observation.The mature ESs of all these species had basically similar strueture: an egg cell, tow synergids and a central cell with a secondary nueleus, the antipodal cells...

The present paper deals with the observations on embryo sacs (ES) isolated by enzymatic maceration in four Campannlaceous species, Platycodon grandiflorum, Adenopora axilliflora, A. tetraphylla, Codonopsis lanceolata. Fixed ovules were macerated in a mixture of pecti nase and cellulase. The mature were cleared with lactophenol for mopholgical observation.The mature ESs of all these species had basically similar strueture: an egg cell, tow synergids and a central cell with a secondary nueleus, the antipodal cells degenerated early. Histoehemical reactions such as PAS reaction, Ⅰ_2-KⅠ treatment, Sudan Ⅲ solation and mercuric bromophenol blue staining were carried out. PAS reaction revealed that all the ESs contained plenty of polysaecharide grandules. These species differed from each othe in some aspects, C. lanceolata had broad ES with sparse ytoplasm and large polysaccharide granules. The ES of P. grandiflorum also contained a lot of oil drops.Based on the above mentioned results, it is concluded that the enzymatic technique is a useful means in comparative studies on ESs but to rapid preparation of specimen and stereographic of ESs.

应用酶解技术分离出桔梗科四种植物(桔梗、轮叶沙参、杏叶沙参和羊乳)的胚囊。对胚囊的形态结构和贮藏物质的变化作了观察比较。它们的成熟胚囊结构基本相同,均由卵细胞、一对助细胞和中央细胞组成。反足器退化较早。但形态、大小等有一定差异。桔梗胚囊狭长,细胞质浓密;沙参(包括轮叶沙参与杏叶沙参)的胚囊也较狭长,细胞质不如前者浓密;羊乳胚囊非常宽大,而细胞质相当稀薄,与前三种植物的差异较大。它们均含有贮藏物质,显微化学反应表明主要系多糖物质。多糖颗粒的形状、大小各有特点,在胚囊受精前后的消长变化也有不同。其中羊乳与其它三种植物之间的差别较大。

Fish flesh, fish viscera,fish liver. fish eggs and dried shrimps were used as samples in comparative experi-ments. The results of this new direct method were extremely close to those of or-dinary method in which lipid was extracted according to Bligh-Dyer's method andfatty acids was esterified according to Metcalfe's method (t

在不需从原料中提取脂质,而直接将磨碎原料中的脂质皂化、甲酯化后,进行气相色谱的脂肪酸分析测定。这种方法与通常采用的先提脂质再行甲酯化的方法进行了比较,结果表明,分析测定的数据与普通法极为一致,其优点是快速、操作方便、节省药品;即使样品很少,用普通法不易提取脂质时,此法也能顺利地完成分析工作。

对72例月经周期正常的健康妇女,分别按月经周期的不同时间,取子宫内膜,以直接法制备染色体标本。结果表明,①子宫内膜中期分裂相,于月经周期的第5~10d即达高峰,持续到月经周期第16d;于周期第17~22d,分裂相明显减少;至月经第23d以后,内膜细胞的有丝分裂活动几近停止。②在正常月经周期的第14d左右可发生排卵,排卵后内膜初受孕酮影响的时间至少在排卵后36~48h,不会严重干扰中期分裂相的出现。③从子宫前壁或后壁内膜取材直接制备染色体标本进行比较,二者无显著性差异(P>0.05)。④所取组织量与获得中期分裂相数目间呈正相关,有极显著意义(P<0.01)。
