Ping chuan-fang prescription is carefully composed accordingly. The clinical investigation shows that PCHF can not only alleviate symptoms and physical sign of the patients effectively, but also shorten the course of disease and obviously can not only alleviate symptoms and physical sign of the patients effectively, but also shorten the course of disease and obviously improve the pulmonary function of the patient. The animal experiment showed that PCHF can prolong the asthmatic time and low the concentration of WBC, EOS, IL-4, ET-1 in the blood and BALF. It can restrain the collection of EOS in the lung and relieve the inflammation caused by EOS. It also can cut down the secretion of the respiratory air-way and relieve the obstruction of it.

The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

On the basis of sand-bodies Isopach figure drawing, the distribution of major reservoir sand-bodies of Neopaleozoic in south of North China Basin was studied. Basing on the distribution of sand-bodies in sequence stratigraphic framework, combining the development and distribution features of barrier and underwater distributary channel, there is a disquisition on the distribution regularity of pay reservoir sand-bodies of Neopaleozoic in this area.

The above facts indicated that silicon accumulation in the rice leaf sheath inside, the leaf surface and the sclerenchymatous cell, played the physical barrier role, delayed the hypha of sheath blight expansion.5、Analysing the physiological and biochemical mechanism of the resistance to rice sheath blight improved by silicon application in several respects.(1) After being inoculated with R.solani, O2 and POD activities disordered, CAT activities obviously declined. O2 producingvelocity in 91SP\'s leaves and leaf sheaths of Si+ rice plants were lower than those of Siriceplants, MDA content in leaves and leaf sheaths of Si+ rice plants were lower thanthose of Si- rice plants significantly in three days after inoculating, SOD、POD、CATactivities in leaf sheaths of Si+ rice plants were higher than those of Si- rice plantssignificantly in one day after inoculating, SOD、POD、CAT activities in leaves ofSi-treatment were higher than those of Si- rice plants significantly in three days afterinoculating. O2 producing velocity and MDA content in Lemont\'s leaves and leafsheaths of Si+ rice plants were lower than those of Si- rice plants significantly afterinoculating, and SOD、POD、CAT activities of Si+ rice plants were higher than those ofSi- rice plants significantly.
