Microscopic observation of ehrlick ascites tumor cell mitosis and metaphase chromosome
艾氏腹水瘤細胞有絲分裂過程的顯微觀察 -
Their flowers and fruits were removed in this experiment to enhance them to take branch roots on the stems, and then the branch roots were used as materials. five mitosis metaphase cells, with their chromosomes well scattered, were counted. chromosome number of hup is 2x = 24, and its karyotype formula is 2n = 2x = 24 = 8m + 12sm + 4st, being to " 3b " of stebbins
本實驗採取去其花、果實，促其莖節上長側根的辦法，以其側根為實驗材料，統計了5個分散較好的有絲分裂中期細胞，其染色體數目為2x = 24 ，核型公式為2n = 2x = 24 = 8m + 12sm + 4st ，核型類型為3b型。 -
Method of metaphase chromosome preparation from scallop was optimized. the gill tissue and embryo before the stage of trochophoro larve were proved to be good materials for chromosome preparation, while excellent chromosomes can hardly be prepared from the gonad tissue or embryo after the stage of trochophoro larve
確定成體扇貝鰓絲或者擔輪幼蟲期的早期胚胎是較為優良的染色體制備取材來源，而性腺材料、進入d型幼蟲期以後的扇貝胚胎則較難以制備優良的染色體分裂相。 -
In the laboratory experiment part, human peripheral blood, cultured cells and icr mice were study objects. the changes of mitotic chromosome numbers were measured by human metaphase chromosome counts and statistic analyzed used x2 - test. the changes of meiotic chromosome numbers were measured by mice one - cell zygote chromosome counts and statistic analyzed usedx2 - test. the effects of low dose ionizing radiation on the expression of topoisomerase ii were measured by immunocytochemistry, western blot and rt - pcr
流行病學結果顯示長期小劑量輻射接觸與染色體不分離呈正相關，為進一步在細胞遺傳學和分子生物學方面研究小劑量電離輻射與染色體不分離關系及其機制，本課題第二部分以外周血、培養細胞、 icr小鼠為研究對象，用外周血染色體計數和單細胞受精卵染色體計數的方法研究小劑量輻射和拓撲異構酶復旦大學2000級博士生學位論文11a抑制劑及其二者的協同效應對有絲分裂和減數分裂染色體不分離的影響，用免疫細胞化學染色、 westernblot 、 rt pcr等方法研究了電離輻射引起拓撲異構酶a表達變化。 -
Upon the optimization of metaphase chromosome preparation from scallop, analysis and comparison on chromosome number and karyotypes were made between the hybrids and their parents
首先，針對扇貝生物的染色體核型研究，對扇貝染色體制備的條件進行了優化。 -
The total number of r - bands found in the chromosomes is 100, which is approximately 1 / 4 to 1 / 5 of that of the vertebrate metaphase chromosome r - bands. they consist of 57 positive, 33 negative and 10 variable bands
在100條r帶中陽性帶有57個，陰性帶有33個，可變帶有10個，約有722 %的染色體區域顯示r帶陽性結果。
