H. armigera, by contrast, must be prepared to counter a wider range of potential toxins. 5.

The UV and IR spectroscopic studies of the monomer films showed that the photoreaction ratio of monomer (about 50%) was higher than the corresponding photosensitive polymer (about 10%, PVCi). The polarized IR spectra proved that obvious anisotropic absorption was displayed in the irradiated photosensitive film. With polarizing microscopy method, we found that these kinds of photoalignment films exhibited good alignment ability, and the stability of the photoalignment film could reach about 100℃. 2 A photosensitive self-assembled monolayer was fabricated that contained photo-cycloadditable groups, such as, coumarin and cinnamate. The reaction process were detected by contact angle method because the IR absorption of monolayer was very weak. The photosensitive self-assembled monolayer promote uniform alignment of nematic liquid crystals by LPUV, and it thermal stability could reach about 130℃. 3 A cationic bolaform amphiphiles was synthesized that had two photosensitive double bonds, and can be polymerized by ultraviolet. A layer-by-layer self-assembled deposition film was prepared in aqueous solution by using this material and poly (sodium 4-styrenesulfonate). The UV-Vis. spectra proved that the multilayers film was uniform and layer-by-layer. When LPUV irradiated the film, the photopolymerizable double bond underwent [2+2] cycloaddition, and the production of the reaction distributed along the polarized direction of incident LPUV. Polarized UV-Vis. spectra indicated that the irradiated self-assembled multiplayer film was anisotropic, and the dichromic ration is about 0.09, it is higher than the spin-coating method of photosensitive polymer or monomer. We used this anisotropic film as alignment layer of nematic liquid crystals, and obtained a uniform and stability alignment result, the static contrast ratio is about 100, which is very close to application of liquid crystal device. This thesis is an instance that the photochemical material was used in the physics region of liquid crystals, the route that was from photosensitive monomer, self-assembled monolayer film to self-assembled multiplayer film was undergone, by this logical research method photoailgnment of liquid crystal was extended and consummated.

We conclude that KB-R7843 has protective effects on contrast media-induced nephrotoxicity. The protective role of KB-R7943 may be related to its positive effects on renal hemadynamics through inhibiting the increase of ET-1 and TXA2 induced by contrast media in the environment of hypercholesterolemia and its cytoprotective influence on renal cells.

据此推导：（1）KB-R7943对高胆固醇血症环境下造影剂注射所致的肾损害有保护作用；（2）KB-R7943对造影剂肾损害的保护作用可能与其阻止高胆固醇血症环境下造影剂注射所致的肾皮质ET-1、TXA2浓度的上升从而阻止高胆固醇血症环境下注射造影剂所致的肾血流动力学的紊乱有关以及其对肾脏细胞的细胞保护作用有关。

DST showed that the pretreatment with dexamethasone can not repress the total number of CRF immunoreactive neurons in the rat model induced by CUMS, by contrast with a normal repression in the number of CRF neurons in rat induced by acute stress. In brief, the rat model induced by CUMS represented decreased body weight, obvious depression-like behavior, hyperactivity in HPA axis and nonsuppression on the DST, which fits the criteria and neurobiological feature of depression.

However, the piercing flavour of LuHsun"s essays made his essays subject to censure by many critics. And LuHsun himself was often mistaken and refuted by the compromising ones because of his sharping critical attitude toward one vital part but ignoring the other aspects of the objects. Especially those readers who never read the articles by LuHsun"s counterparts would think him too harsh, but the value of LuHsuns essays could be uncovered sufficienty by contrast to those by the counterparts.

鲁迅杂文深刻犀利的文风也多受指责；其对生活、社会问题看法超出一般人的理解范围而受误解；其只抓要害、不及其余以及连类而及，对具象的类型化批评的论辩方式为中庸、和为贵的受众所指责，尤其是难以见到鲁迅论辩对手文章的读者，更会留下刻薄的印象，因为鲁迅的现实性极强的杂文与对立之文共存才显现它的价值。
