At the surface of the pollen grains there are three types of aperturates, including three porates type, three colpates type and three porate - colpates type ; and four types of sculpture, namely, reticulate, striate, striate - reticulate and verrucate. the upper epidermal cells of the leaves of 12 species plants are detected with hpias - 1000 image analytic system through the treatment of binarization, and the experimental methods are proved stable. the results indicated that the waviness of the anticlinal walls ( sfc ) and the ratio of the feret ' s diameter ( slf ) of the epidermal cells of the middle lamina in the third node of leaves starting from the lowerest part of the stem have a relative constant range and could distinguish from each other. oieanolic acid, l, 5, 8 - trihydroxy - 3 - methoxyxanthone and swertiamarin are separately detected on the tlc, and the different chromatogram of various plants can be considered as characters of identification. the contents of oleanolic acid in 12 species of plants are determinated by hplc, but among the different plants and botanical organs their contents are different, and the highest content in flowers
本文對川鄂產獐牙菜屬藥用植物資源進行了野外調查、標本採集和鑒定,對12種乾燥藥材的性狀進行了描述,提供了可以鑒別的特徵。通過掃描電子顯微鏡觀察的12種本屬藥用植物的花粉粒均為單粒花粉,萌發
孔有3
孔型, 3溝型和3
孔溝型三種類型;表面紋飾包括網狀紋,條狀?網狀紋,條狀紋和
瘤狀紋四種類型。用hpias ? 1000高清晰度彩色病理圖文分析系統對葉片上表皮細胞作圖像分析,並進行方法學研究,結果表明,同種植物莖上第3節葉片中段主脈和第1側脈之間葉上表皮細胞垂周壁彎曲程度sfc值和細胞縱、橫向直徑的比值slf值,種間有顯著差異,每種都有相對恆定范圍值。
There are mat - shaped thickenings at the base of spines in the certain species of machilus. the most reliable characters for the delimitation of species are the features of the perforation, mat - shaped thickenings. the evolutional trends of the extine ornamentations in the pollen grains were discussed

Conclusion ( 1 ) depending on location , size and invading extension of the tumor , above different approaches are adapted selectively which can provide excellent exposure and allow for an aggressive resection of the tumor. ( 2 ) the tumor tissue of the cavenous sinus and foramen lacerum is resected carefully by microsurgery. ( 3 ) the dural deficiecy must be repaired and sutured tightly to avoid craniocerebral fluid leak
