The mechanism enhancement of the optical brightener is not known. shapiro et al. postulated that selected brightener including m2r inhibit or alter the chitinous peritrophic membrane ( pm ), creating gaps in the membrane or gut lining and perhaps allowing more virions to pass from the gut lumen into the hemocoel
光增白劑對桿狀病毒的增效作用的機理存在兩種推測一種觀點認為光增白劑是通過破壞圍食膜結構的完整性，促使更多的病毒粒子穿越圍食膜而發動感染的；另一種意見認為光增白劑能延遲中腸上皮細胞的脫落，促進病毒的復制繁殖。In this thesis, the development of emulsion polymerization theory and related new technologies are comprehensively reviewed, and the synthetic technologies of acrylate latex modified by organosilicon both at home and abroad are also reviewed. based on the current development and research in this field, attentions of this study are focused on three ways for preparing novel acrylate latexes modified by organosilicons, that is, 1 ) the acrylate monomers are copolymerized with unsaturated silicons by emulsion copolymerization ; 2 ) a new latex with microphase separation morphology is synthesized, which shows a core - shell structure character ; 3 ) soap - free polymerization is explored for preparing a higher - performance latex using an unsaturated silicon monomer, different acrylates and a reactive emulsifier. by using techniques of delaying addition of organosilicon monomer and a hydrolysis inhibitor, the hydrolysis and condensation of 3 - ( trimethoxysilyl ) propyl methacrylate during polymerization can be effectively prevented, as a result, organosilicon content in the macromolecular chain is increased
同時採用有機硅單體延遲滴加及添加水解抑制劑等技術，有效防止了-甲基丙烯酰氧基丙基三甲氧基硅烷在乳液聚合過程中的過渡水解及縮合反應，提高了聚合物大分子鏈中有機硅鏈節的含量；利用紅外光譜與差示掃描量熱儀對產物分子結構進行了表徵，並通過對共聚產物力學和吸水率的測試，證實了本研究所制備的有機硅改性丙烯酸酯共聚物具有比純丙烯酸酯聚合物更優良的力學及耐水性能；從分子設計角度出發，利用醇解反應合成出水解、縮合反應速率較慢的兩種新型不飽和有機硅單體： ?甲基丙烯酰氧基丙基三乙氧基硅烷和?甲基丙烯酰氧基丙基三異丙氧基硅烷；利用核磁共振對新型硅烷單體結構進行了證實；研究表明利用新型硅烷單體可以制備出高硅烷含量的有機硅改性丙烯酸酯乳液，且其聚合產物具有較高的力學及耐水性能。Rat cumulus - enclosed oocyte ( ceo ) and denuded oocyte ( do ) both spontaneously resume meiotic maturation in vitro, when cultured for 2h, the germinal vesical breakdown percentage of do reaches up to 88 %, and ceos get 53 %. oocytes begin to extrude first polar body 1 ( fb1 ) when cultured for 8h. mouse oocyte spontaneous maturation in vitro can be inhibited by 4mm hypoxanthine ( hx ) or 25um 3 - isobutyl - methylxanthine ( ibmx ). while, 4mm hx can not inhibit the spontaneous maturation of rat oocyte, and the lowest effective concentration of ibmx to inhibit rat oocyle spontaneous maturation in vitro is 50um. treated with the same concentration of ibmx, gvbd percentage of rat ceo is lower than that of do, the results indicat that cumulus cells delay rat oocyte spontaneous maturation and potentate the inhibition effect of ibmx, but it ' s not the case on mouse
Ceo和do培養8h時都開始排出pb1 ；在卵母細胞成熟抑制模型中， 4mm次黃嘌呤（ hx ）和25 m的異丁基甲基黃嘌呤（ ibmx ）是小鼠卵母細胞成熟的有效抑制劑，但4mm的hx抑制大鼠卵母細胞成熟效果不理想，用hx - m199和hx - mem培養24h ， gvbd率分別為61 ， 81 ，而ibmx有效抑制大鼠卵母細胞自發成熟的最小濃度為50 m ， ibmx可以降低大鼠ceo和do的gvbd率，但ceo中的卵母細胞gvbd率要顯著低於do的gvbd率， 100 m的jbmx處理24h后，大鼠ceo和do的gvbd率分別為24 ， 84 ，提示卵丘細胞的存在可以延遲大鼠卵母細胞的自發成熟，有助於抑制卵母細胞成熟，但在小鼠上ceo和do的自發成熟差異不明顯。
