Since the Km〓 gene of pCS4 and pCS11 was derived from the mesophile plasmid pUB110 and coded for a thermolabile protain, it conferred Km〓 phenotype on the host cell at 48℃ only. Mutant Km〓 gene was obtained by selecting for Km〓 phenotype at elevated growth temperature. In this way improved vectors pCS5 and pCS12 were obtained, which can be used at 65℃ by Km selection.

利用提高培养温度后选择卡那霉素抗性表型的方法，从编码不耐热蛋白质的卡那霉素抗性基因出发，得到了提高其耐热性的突变的卡那霉素抗性基因，从而改造了CS4和pCS11，得到了适用温度达65℃的改进的载体质粒pCS5和pCS12。

RT-PCR was applied to detect changes of hepatic hepcidin gene expression on model different stage. Bone density was detected and decalcification bone microtome section and hepatic histological section were observed and analyzed on the 14th day. Results Compared with control group, hepatic hepcidin gene expression of test group on different stage had obvious differences.

d每天灌胃，14d后形成骨质疏松模型；在实验组中采用RT-PCR方法分别观察灌胃第1、3、5、8、9、10、12、14d肝脏铁调素基因表达变化；要第14d还检测大鼠骨密度、分别脱钙骨切片、观察肝组织切片。

In D3 gene with 5 site mutations. There exists individual variation in the COII gene, but this variation is less than that among other members of Myzomyia Series such as An. aconitus, An. jeyporiensis, etc. In addition, one haplotype different from both An. minimus A and C was found in these 3 genes studied.②The genetic distance between An. minimus A and An. minimus C is less than that among other members of Myzomyia Series. Molecular trees based on different genes and different methods show that An.

种系发生研究表明，微小按蚊复合体亲缘种A、C间的遗传距离远小于与之近缘的同系其它成员间的距离。2个分子标记3种方法构建的基因树显示，微小按蚊A、C的种系地位非常固定，不同地域来源、不同变异类型的微小按蚊始终在同一分"枝"上，与迈蚊系其它成员相比，呈现其相对稳固的单源性。
