The ultrastructure of the hepatocyte in bufo bufo gargarizans cantor between pro - hibernation and initial post - hi be rnation was studied in this paper. the results show that : 1. the hepatocytes in pro - hibernation period have very plenty of glycogen granules, but nearly not glycog en granules in post - hibernation period ; 2. the hepatocytes in pro - hibernation peri od have very developed rough endoplasmic reticulum, but a few scattered dilatant rough endoplasmic reticula in post - hibernation period ; 3. the quantity of mitocho ndria, and the structure of nuclei and bile canaliculi in pro - hibernation period have not obvious difference from that in post - hibernation period ; 4. two types o f hepatocytes in pro - hibernation were found. the significance of the results men tioned above is also discussed
冬眠前和出眠初期的中華大蟾蜍肝細胞的超微結構有如下特點： （ 1 ）冬眠前肝細胞堆積有大量糖元顆粒，而出眠初期幾乎無糖元顆粒； （ 2 ）冬眠前肝細胞的粗面內質網非常發達，而出眠初期的粗面內質網不發達，常呈零散膨大； （ 3 ）線粒體的數量，細胞核和膽小管的形態結構在這兩個時期無明顯差異； （ 4 ）冬眠前肝細胞可分為兩種不同的類型.對上述結果的生理意義作了討論At present, in an attempt to stimulate specific antitumor immunity, experimental models and clinical studies are currently evaluating the potent antigen - presenting capacity of dc combined with single or multiple tumor antigen epitopes. however, there are several problems in utilizing pulsing dc with synthetic immunodominant peptides from identified antigens. 1 ) the potential induction of tolerance ; 2 ) the need to determine the patient ' s hla haplotype, the limitation of therapy to patients whose tumors express defined specific tumor antigens in the context of the correct hla phenotype, the unavailability of peptides for all hla haplotypes ; 3 ) the lack of cd4 help cell - related epitopes for most antigens ; and 4 ) the ctl resulting from such protocols have a good in vitro capacity to kill peptide - pulsed target cells but only a modest capacity to kill tumor cells
但是，學者們發現這一療法存在著如下的缺陷：單一ctl表位抗原肽的應用其抗腫瘤作用弱於多種腫瘤抗原的聯合應用，且有誘導免疫耐受的潛在危險，有時反而會促進腫瘤的生長；事先需對患者的hla單倍型進行鑒定，以確定ctl表位與hla單倍型是否匹配，目前尚缺乏能與所有hla單倍型相匹配的ctl表位，從而限制了這一療法的應用；這一療法所產生的ctl在體外能有效殺傷經腫瘤抗原肽共孵育過的靶細胞，但對腫瘤細胞的殺傷能力較弱：這種l表位抗原肽缺乏cd4汀h細胞相關的表位，因此，不能誘導有效的th細胞免疫應答。High feed intake pre - farrowing can also lead to bacterial endotoxin production in the gut, which can have an adverse effect on the muscle cells that trigger milk letdown with the same results and make the sow unwell
產小豬前採食大量的飼料也會導致細菌內毒素在內臟產生，這樣會對肌肉細胞產生不利的影響，那就是引發產奶量下降並且導致母豬亞健康的原因。We detected the transcription and translation change of different thrs genes by semiquantitative reverse transcription - polymerse chain reaction ( rt - pcr ) analysisjelisa respectively. at same time the differentiated cell were identified by immunocytochemistry method. results ( l ) nsc induced by mitogens were nestin - positive and incorporated by brdu
以pdgf 、 t _ 3對nsc進行誘導分化，並分別用rt - pcr半定量法、 elisa法檢測nsc在不同誘導因子作用下分化前後thr各亞型在轉錄與翻譯水平上的表達變化，用免疫細胞化學方法鑒定分化后的細胞類型。The synthesis of poly ( - hydroxybutyrate - co - - hydroxyvalerate ) by the strain g - iiiy from different precusor was studied. it was found that the strain g - iiiy could accumulate phbv with sucrose as carbon source and propionic acid or valeric acid as precursor. in 2l self - controlled fermentor, the dry cell weight, phbv concentration and phbv content reached 35. 8g ? l - 1, 22. 6g ? l - 1 and 38. 4 % respectively in the case of fermentation for 42 hours and the propionic acid as precursor
研究了添加不同前體物， g - y菌株生產聚-羥基丁酸和聚-羥基戊酸共聚物（ phbv ）的發酵條件，結果表明，此菌株能以丙酸或戊酸為前體，在蔗糖為碳源的條件下合成phbv共聚物；在2l發酵罐中，以丙酸為前體，發酵16小時開始流加丙酸，根據發酵液ph值變化控制丙酸流加量，發酵42小時，細胞干重、 phbv產量和含量分別達到35 . 8g / l ， 22 . 6g / l ， 63 . 13 。4. effect of resolution vector on the expression of pesticidal crystal protein genes this work successfully introduced pesticidal crystal protein genes into crystal negative strain bmb171 by using resolution shuttle vectors. after resolution, the expression of cry1ac and cry 1c genes have no obvious change, but the expression of cry3a genes has great increase in the same condition
解離反應對殺蟲晶體蛋白基因表達的影響成功地利用解離載體將crylac10 ， crylc和cry3a基因導入蘇雲金芽胞桿菌無晶體突變株， crylac和crylc基因解離前後的表達量和殺蟲毒力未見明顯變化， cry3a基因在相同條件下則表達量有所提高，至於為何只對基因cry3a有作用尚不清楚，國內外也未見有人作相關報道。The metastatic tumor on the forearm continued to progress and the patient eventually died of the disease 32 days after diagnosis even after immediate concurrent chemoradiotherapy

貝南先生對師父關心並派同修前來幫忙這些從未見過面的同胞之博大愛心稱贊不已，同時他也提到，雖然平常彼此並不相識，不過在災難發生之時，大家皆能完全投入，發揮人饑己饑人溺己溺的精神，對同胞們伸出援手，幫助那些最需要幫助的人，就像此次許多救災消防及工作人員們暫時放下親友家人，日以繼夜地投入工作，都是因為由內心深處發出人類最原始的慈悲心及愛心。Title ： overseas chinese home town village development transformation research ? ? case study of fuqing city xincuo town suanling villiage abstract ： the province of fujian is famous for large quantity of people overseas. these people always try their best to help their home town develop. the overseas chinese capital has deeply involved in fujian, and to some extent, it is one of the main motives of the fujian ' s economic miracle. the research on overseas chinese and development of native place has getting hot in mainland china and also in the world. but for some reason, fieldwork and case studies, to some extent, are neglected in research
在僑胞的投資與捐助下，福建省經濟社會發展取得了巨大進步，走出了一條有特色的僑鄉發展道路。這引起了學術界及政府的廣泛關注。針對華僑華人及僑鄉發展的研究不斷升溫，然而目前此類研究中在田野調查和實證研究的基礎上形成的研究成果較少，而且實證研究中又側重於有大華僑大資金注入的僑鄉，對那些缺乏大筆資金注入的僑鄉農村則關注不足。Standing beneath this serene sky, overlooking these broad fields now reposing from the labors of the waning year, the mighty alleghenies dimly towering before us, the graves of our brethren beneath our feet, it is with hesitation that i raise my poor voice to break the eloquent silence of god and nature
