According to measured data, testis sizes from animals captured in september 2000 were different remarkably from that in april and july 2001, and not differences among their age groups, which was indicated that l. lagurus in september 2000 did not have reproductive abilities. by use the same method, we have observed that l. lagurus in april 2001 and groups from - age and - age ( old ) in july 2001 have reproductive abilities. in addition, the reproductive ability from the - age group in july 2001 was intermediated between the groups in september 2000, - age group in april and - age group in july 2001
我們對不同時間參與繁殖的雄鼠睪丸大小的測定結果表明， 2000年9月雄鼠睪丸大小與2001年4月和7月的有顯著性差異，表明2000年9月草原兔尾鼠雄鼠進入繁殖休止期； 2001年4月種群中齡和齡雄鼠睪丸大小無顯著性差異，與2001年7月的相比有顯著性差異，但與2001年7月種群的齡鼠和齡鼠的相比無顯著性差異，表明2001年4月和2001年7月種群的齡和齡草原兔尾鼠雄鼠具繁殖能力； 2001年7月的齡雄鼠睪丸大小與2000年9月的有顯著性差異，表明該時期齡雄鼠的繁殖力介於2000年9月種群和2001年4月和7月種群的齡鼠和齡鼠之間。 -
According to the live coefficient c, we modified the predictions for this age group and come to a conclusion that is corresponding to actual field data. in other words, the numbers of - age and - age were nearly zero with their densities below 4 / hm2. these results suggest that l. lagurus population began to decline
運用校正後的存活系數繼續預測，其結果與2001年9月的野外調查結果基本一致，證實當年草原兔尾鼠的數量非常少，低於4 . 0隻/公頃，且齡鼠和齡鼠幾乎為零。 -
In addition, for construction of prototype dna vaccine, pcmv4 - lzp3, the cloned lzp3 full - length cdna was subcloned into a eukaryotic expression vector, pcmv4. these preliminary results could lead to further investigation for the development of immunocontraceptive vaccine based on lzp3 for lagurus population control
本工作首次克隆了草原兔尾鼠卵透明帶3全長cdna ，已向genebank申請注冊為新基因，保護了我國的野生動物基因資源，為哺乳動物生殖機理的研究提供了新的資料。 -
The harmfulness of l. lagurus is a serious problem for long time, because of undulation of population number and perniciousness
由於其種群數量變動較大，加之它對草場的危害嚴重，長期以來一直困擾著人們。 -
As one of the most promising population control tools in the world today, immuno - contraception using zona pellucida glycoprotein antigens, specifically zp3, may be used to control lagurus population
卵透明帶3 （ zp3 ）蛋白是哺乳動物生殖過程中介導精卵結合的關鍵因子，已被用作免疫不育控制鼠害研究的主要靶抗原。 -
After rt - pcr of total rna isolated from the ovaries of lagurus lagurus, the lzp3 cdna was cloned into pucm - t and further identified with sequence analysis
將擴增產物連接到pmd18 - t載體上進行測序，序列分析表明已克隆出lzp3全長cdna 。 -
With a set of primers designed according to the sequence of the cloned cdna fragment, the 3 " and 5 " ends of the cdnas were obtained by 5 " and 3 " rapid amplification of cdna ends ( race ), respectively. combining the sequences of the 3 " ends, 5 " ends and cloned partial cdna, the full - length sequence of the lagurus lagurus zp3 ( lzp3 ) cdna was assembled
根據已測序的lzp3保守序列設計特異性引物，使用3 '和5 ' race的方法擴增lzp3cdna的3 '末端和5 '末端序列並進行測序，所測序列經與lzp3保守序列相互重疊、核對與拼接，獲得了lzp3全長cdna序列。
