Isozymes in different tissues of three stains of crucian carp were studied comparatively . the results indicated that pengze crucian carp is different from silver crucian carp in biochemical level , they probably came from different region . the electrophoretogram of pengze crucian carp and silver crucian carp all included the basal patterns of wild crucian carp 通過對三種鯽魚品系不同組織同工酶的電泳圖譜的比較研究,揭示了彭澤鯽和銀鯽至少在生化水平上已有明顯的分化,很可能起源于不同的地區,獨立演化而形成。

The formation of the population of the allotetraploid hybrids of red crucian carp and common carp is the first case in the world which both the female and the male of allotetraploids are fertile , they are the good materials for studying the biological characteristic of tetraploid animals , this paper reports the hereditary characters of allotetraploids including the stability of hereditary gynogenesis and androgenesis 異源四倍體鯽鯉是世界上首例人工培育的兩性可育的四倍體魚,這為研究四倍體的生物學特性提供了良好的實驗材料,本文對異源四倍體鯽鯉的遺傳特性進行了研究,主要包括其遺傳穩定性、雌核發育、雄核發育方面的研究。

For the cryogenic preservation of fish , in this paper we made the primary culture of the kidney of allotetroploid crucian carp and primary studies were carried out on cryopreservation culture offish embryo cells derived from misgurnus auguillicaudatus or grass carp , the results of the experiments are as follows : the primary cell culture of the kidney tissue derived from allotetroploid crucian carp was carried out using tissue adherent culture , the primary observations of the growth conditions and morphology of the primary culture and subculture cells which originally come from the kidney tissue were also made 本文主要從魚類種質保存的目的出發,一方面以四倍體鯽鯉魚為材料,對四倍體鯽鯉魚腎臟組織進行初步培養,為建立相應細胞庫及下一步培養凍存的魚類胚胎細胞奠定基礎;另一方面,以魚類組織細胞培養技術為基礎,泥鰍胚胎細胞為材料,對魚類胚胎細胞凍存培養方法進行初步研究,并應用該技術方法對草魚早期胚胎細胞進行凍存培養實驗。報告如下:本文用組織貼壁法對四倍體鯽鯉魚腎組織進行原代、傳代培養。

Using cd , cu , zn and cr as experimental toxicants and crucian as experimental creature , we employed the environmental biotechniques ( flame atomic absorption spectrophotometry , the method of improved pyrogallol autoxidation and electron microscopy ) to study the acute toxicity and secure concentrations of heavy metals to crucian ; the accumulation and distribution of mixed heavy metals to fingling crucian ; the activities of superoxide dismutase ( sod ) of gill and liver tissues and the hispathological and ultrastructural change of superfine structure of liver and kidney of crucian after cadmium exposure . through which , we intended to fully and systemically study the toxic influence of heavy metals to fish , and preliminarily discuss the influence of heavy metals pollution to the diversified level of fish such as individual , organ , tissue , cell and molecule . thus we tried to provide scientific evidence to establish preventative management measures , avoid and relieve the harm of heavy metals pollution to aquicolous ecosystem in time 隨后以這幾種重金屬作為實驗毒物,以鯽魚為實驗動物,應用環境生物技術、火焰原子吸收分光光度法、鄰苯三酚自氧化法、透射電鏡等技術研究了重金屬cu 、 zn 、 cd和cr對鯽魚的急性毒性及其安全濃度評價、混合重金屬在鯽魚幼體組織內的積累和分布、 cd對鯽魚鰓和肝臟中sod活性的影響、 cd對鯽魚肝細胞和腎細胞超微結構的影響等,全面和系統地研究了水環境中重金屬暴露對魚類的毒性影響,初步探討了重金屬污染對魚類的個體? ?器官? ?組織? ?細胞? ?分子等各水平層次的影響,為制定漁業生產上預防性的管理措施提供科學依據,及時避免或減輕重金屬污染對水生生態系統造成的損害。

Therefore , one can not claim to have been to the yellow mountains without reaching the celestial capital peak . descending the celestial capital peak westwards , travelers go through the immortal gate keeper cave with vivid peach - resembling rock formations on the cave , pass crucian carp peak formed during the glacial period and cross the heavenly bridge where the sea exploring pine stands 在天都峰的西側往下走,人們要依次經過“仙人把洞門” ,鯽魚背和天橋, “仙人把洞門”上有形狀如桃花的巖石,天橋鯽魚松形成于冰川時期,天橋上生長有探海松。

The results showed : ( 1 ) the activity concentration of 95zr in water reduced quickly for subsidence , soil absorption , crucian intake , hornwort ' s absorption and adsorption . the dynamics of its disappearance accorded with binomial index regression law : cw . = 43 . 36e - 1 . 74t ' + 12 . 85e - 0 . 15 ( 2 ) the hornwort had stro 結果表明: ( l )從水體中引入的95zr由于沉降、土壤吸附、被魚體攝入和金魚藻的吸收、吸附作用使水體中的gszr比活度呈快速下降,其消失動態符合二項指數衰減規律, cw = 43 . 36e . , . 74t + 12 . 85e一住‘ ” 。

The safe concentrations of zn , cd and cr to crucian were far exceeded the standard . the short - term accumulation and distribution in young crucian tissue of mixed secure concentrations of heavy metals cu , zn , cr and cd pollution was studied . the results showed that associated interaction of the four heavy metals was synergistic effect of accumulated toxic 研究了安全濃度的混合重金屬cu 、 zn 、 cr 、 cd污染在鯽魚幼體組織中短期的積累和分布,實驗結果表明: cu 、 zn 、 cd和cr四種重金屬之間的聯合作用為毒性劇增的快同作用。

2 . the gynogenesis of allotetraploid hybrids without the treatment to double the chromosome number , the diploid eggs produced by the females of tetraploid hybrids of red crucian carpx common carp were able to develop to living diploid fish after subjecting to activation of the uv - irradiated sperm 人工誘導異源四倍體鯽鯉的雌核發育異源四倍體鯽鯉能產生二倍體卵子,用uv處理鏡鯉的精子,不進行染色體的加倍處理,能獲得二倍體雌核發育魚,通過冷休克對“受精卵”進行處理,仍然獲得了二倍體雌核發育魚。

The appearance of the gynogenetic fish was similar to that of f2 hybrids , the diploid gynogens were able to produce diploid eggs that were proved by the presence of the triploids with 150 chromosomes among the offspring produced by mating the diploid females of the gynogens with the diploid males of the red crucian carp 在第三年可育的雌核發育魚的比例有所增加。在外形上與湘螂fz相似,在繁殖特性上,二倍體雌核發育魚也與湘螂fz相似,能產生二倍體卵子,其與紅螂后代的染色體數為3n = 150 。

The results showed that the electrophoretogram patterns of isozymes , serum and muscle protein of bumper crucian carp were the same as those of its female parent and significantly different from its male parent . it is speculated that the function of heterogeneous sperm was only in dna level and not behave on the isozyme expression of grown progeny 結果發現:異源子代的血清、肌肉蛋白和同工酶的電泳圖譜與母本彭澤鯽相同而與父本海鯉顯著不同,推測異源精子的作用可能是在dna水平上對后代產生影響,這種影響沒有表現在成體同工酶的表達上。

Two isozymes ( peroxidase and - amylase ) of six tissue ( heart , liver , kidney , brain , eye and muscle ) of “ allogynogenetic crucian carp “ , its female parent qihe crucian carp and male parent red carp ( cyprinus carpio ) were analyzed by vertical polyacrylamide gel electrophoresis 摘要采用聚丙烯酰胺垂直平板電泳,對異育淇鯽及其母本淇鯽和父本興國紅鯉的6種組織(心臟、肝臟、腎臟、腦、晶狀體和骨骼肌)中的過氧化物酶和-淀粉酶同工酶進行比較研究。

Descending the celestial capital peak westwards , travelers go through the immortal gate keeper cave with vivid peach - resembling rock formations on the cave , pass crucian carp peak formed during the glacial period and cross the heavenly bridge where the sea exploring pine stands 在天都峰的西側往下走,人們要依次經過“仙人把洞門” ,鯽魚背和天橋, “仙人把洞門”上有形狀如桃花的巖石,天橋鯽魚松形成于冰川時期,天橋上生長有探海松。

Gui miao ( college of life science , south china normal university , guangzhou 510631 ) pengze crucian carp , carassius auratus of pengze , is a unique model system for studying evolutionary genetic and selective breeding , owing to its specific genetic background and reproductive modes 結果表明同源和異源精子激發的胚胎發育過程在mdh 、 ldh和sod同工酶表達上存在明顯差異,充分說明了“異精生物學效應”的存在。

If you thought you were the champion of holding your breath under water as a kid , think again . crucian carp , a fish closely related to the goldfish , can live months without oxygen , scientists have discovered . fish holds breath for months 挪威科學家日前在英國實驗生物學協會年會上說,生活在淡水中的鯽魚crucian carp是最強的“憋氣高手” ,因為即使是在沒有氧氣的情況下,鯽魚仍然可以“好好地”活上好幾個月。

The mature females were only found among the two - year old gynogens , not being found among the one - year old gynogens , indicating that the ovary in the gynogens developed slowlier than that in the normal diploids such as the red crucian carp 二倍體雌核發育魚的性成熟比普通的二倍體鯉、魚即魚的性成熟得晚,在一齡的雌核發育魚沒有發現達到性成熟的個體,只有到二齡時,才發行性成熟魚。
