The cortical cells had thin walls and mitochondrium, and nucleus wassurrounded by chloroplasts, and vesicles were next to cell plasmalemma. However, cellwalls of velamen, cortex and exodermis in the mycorrhiza of D. nobile had ring orpapillary thickenings in many cases. The hyphae were surrounded by moremitochondria and vesicles of plant, and the hyphae were digested and their structure waschanged at last. The cell wall of endodermis also had typical ring thickenings, and manysieve orifices in sieve tube elements of phloem were covered by callose, while therewere liaison cords in a few sieve orifices.

金钗石斛菌根的根被细胞的细胞壁多处出现环形圈，外皮层细胞壁加厚，木质化，也有环形圈存在，皮层细胞细胞壁多角形明显，加厚，皮层细胞中存在被消化、失去结构的真菌菌丝，在菌丝周围有较多的线粒体、小泡，内皮层细胞的细胞壁呈现的典型的加厚及木质化环形圈，韧皮部筛管的筛板结构，绝大多数筛孔已为胼胝质所覆盖，仅个别筛孔中还存在连络索。

Result］ The extracted liquid from D. stramonium could decrease the germination rates of 4 vegetables and the seed germination of tomato and pepper. After treatment by 0.2, 0.4 g/ml extracted liquid , the seed germination of tomato and pepper were decreased by 10.2％, 9.4％ and 46.7％, 34.7％ than that of CK resp. The extracted liquid at 0.2 g/ml could inhibit the growth of vegetable root, but had some promotion on growth of vegetable stem. The extracted liquid at 0.4 g/ml had the strong inhibition on the growth of vegetable root, but its inhibition on growth of vegetable stem was greatly variable in different species.

结果］曼陀罗浸提液可降低4种蔬菜种子的发芽速率，降低番茄和辣椒种子的发芽率；0.2、0.4 g/ml曼陀罗浸提液处理后，番茄和辣椒种子的发芽率分别比对照降低了10.2％、9.4％和46.7％、34.7％。0.2 g/ml曼陀罗浸提液抑制蔬菜根的生长，而对茎的生长却表现出促进作用；0.4 g/ml曼陀罗浸提液对蔬菜根的生长有很强的抑制作用，对茎段生长的抑制作用因物种不同而有很大差异。

Results show that root elongation and the mitotic index of the root tip cells were significantly decreased with the increasing Cd concentration and treatment duration.

结果表明，随着Cd浓度增加和处理时间延长，水稻幼苗根的生长及根尖细胞有丝分裂指数明显降低。

Nickel-Titanium instruments have become widely used in the endodontic treatment. However, their unexpected separation was a serious concern in endodontics. To date, no scientific methods have been developed to evaluate the functional lifespan of Ni-Ti instruments. In this study, we used resonance frequency analysis to nondestructively detect the fatigue life of Ni-Ti instruments to determine the feasibility of this technique for use in the clinic.

镍钛合金根管锉已经广泛的使用在牙髓病的治疗上，但其无预警的断裂也是令牙医师关心的问题，之前并无一科学性的方法来评估镍钛合金根管锉的寿命，而本研究室利用自然频率的分析方式对镍钛合金根管锉做非破坏性的疲劳检测，确定此方式可行且在临床上有应用的价值。
