In order to investigate the ontogeny of the pituitary prolactin ( prl ) expression of sheep fetuses during gestation , the pituitary glands were collected at days 60 , 90 , 120 of gestation , the first day after birth , respectively . the cells containing the prolactin ( prl ) were detected using immunohis ' ochemistry method 為了研究綿羊胎兒垂體中催乳素細胞( lactotrophs )的發育和功能變化，分別在胎兒發育的第60 、 90 、 120天和出生期采集垂體，利用免疫組織化學方法研究了垂體中催乳素( prolactin ， prl )的表達及其變化。
In this paper the floral ontogeny and the ovary development of rivina humilis l . were observed . the results showed that ( 1 ) the tepal primordia initiated in 2 / 5 spirals . the abaxial one initiated first , then the adaxial one , finally the lateral two initiated nearly simultaneously . the third one initiated on the position near the first tepal , and there is a gap between itself and the second tepal . ( 2 ) the 4 stamineal primordia initiated in one whorl at the same time . ( 3 ) the carpellary primordium initiated from the abaxial side of flower primordium ; the carpellary primordium grew upwards and towards axis after it was formed , therefore an elliptic orifice was formed at the adaxial position of ovary , which was the remainder of the mouth of ovary before the ovary was fused completely . with the ovary maturing , the orifice was narrowed because of the ovary growth , at last fused completely . the gynoecium is composed of a single carpel . ( 4 ) in the series developmental sections of ovary , the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed 對數珠珊瑚的花器官發生和子房的發育過程進行了觀察.結果表明: ( 1 )數珠珊瑚花被呈2 / 5螺旋狀發生,遠軸側的1枚先發生,其次為近軸側的1枚發生,最后側方的2枚花被幾乎同時發生,第3枚花被在靠近第1枚的位置發生,第2枚和第3枚之間有1個空隙; ( 2 ) 4枚雄蕊是同時發生的; ( 3 )心皮發生于分生組織的遠軸側,心皮原基形成后,向上向軸生長,在子房成熟前在近軸側非正中位形成1個孔,該孔為心皮最終愈合前的殘跡,到子房成熟時,因子房的生長孔被擠壓縮小,在進一步的生長過程中愈合.子房由1枚心皮構成; ( 4 )從子房發育過程的切片看,該植物的胚珠是在子房發生后不久發生的,子房上的圓孔形成時,從近軸側的分生組織發生胚珠原基,由胚珠原基分化出珠被與珠心
So far few studies have examined the ontogeny of the overall synaptic responses in rat hippocampal ca1 neurons during postnatal development a systematical study of the evoked synaptic responses during development is useful for understanding the developmental integration of neural signals on the ca1 pyramidal neurons 到目前為止，還未見對發育過程中大鼠海馬ca1錐體神經元總突觸反應的生后發育進行研究的報道，因此對發育過程中誘發的突觸反應進行系統的研究有利于闡明ca1錐體神經元對神經信號的發育整合。
The trend is refered to combine the evidence from several genes representing both nuclear and organella genomes with morphology , ontogeny and life history for systematic studies ; while studies at the population level by applying molecular techniques with high differenciation lead an important direction 指出同時應用能夠代表核和細胞器基因組的多個基因結合形態、個體發育和生活史進行系統學分析是其必然發展趨勢；而應用高分辨率的分子手段進行居群研究是一個重要的發展方向。
Ontogeny three types of female cones of ephedra are recognized according to the number of seeds per cone , namely uni - ovulate cone , bi - ovulate cone , and tri - ovulate cone . it is suggested that terminal bud of primary cone axe is developed in tri - ovulate cone and disappears in bi - ovulate cone 這三種類型也代表了麻黃屬球花演化的三個階段，三胚珠球花代表麻黃屬雌球花的原始式樣，而單胚珠雌球花則為麻黃屬雌球花最為特化的式樣。
Mouse homeobox gene pem was newly isolated in 1990 ' s . its expression pattern during the murine ontogeny and in the adult tissues is unique , namely , in a stage and spatial specific manner Pem基因在小鼠發育過程及成體部分組織中呈時間和空間特異性表達，并在一系列腫瘤細胞株中持續表達。
The ontogeny and phylogenesis of vessel elements in litchi chinensis . are also discussed 分別對其進行了描述，并從導管分子個體發育與系統發育的角度進行了討論。
