Software and results were saved in EXCEL for consequent statistic operation and obtaining chromosome patterns. 4 indexes were chose, such as chromosome karyotype, C-band pattern, chromosome behavior and B chromosome for comparative analyses, and adopted SPSS to reconstruct dendrogram. Combined with studies on insect morphology and insect geography, we made a detailed analysis and speculation on the relationship of taxa concerned. Finally we got the conclusions as follows: 1. The number of chromosomes in grasshoppers of Oedipodiae is 2n 〓=23=22+XO. All chromosomes are telocentric chromosomes. Most of the genome formulas are 3L+6M+2S+X and 3

论文选取染色体核型、C-带带型、染色体行为和B染色体这4个方面的指标进行比较分析，运用SPSS系统分析软件建立表达各属和各种之间亲缘关系的系统树，并结合昆虫形态学和昆虫地理学等方面的研究成果，对其亲缘关系进行了比较详细的分析和推测，得出以下结论：一、斑翅蝗科蝗虫的染色体数目都稳定在2n〓=23条，性别决定机制是XO型，染色体均为端部着丝粒，染色体组式以3L+6M+2S+X和3L+7M+1S+X这两种类型为主，即3对大型染色体，6～7对中型染色体和2～3对小型染色体，X染色体以中型为主，在染色体组中主要排列为4～7位。

RESULT: 1.Ouabain act on lens sodium-pump,under the LM,lens anterior capsular membrane discontinuous,epithelium cells clustered,occluding zonule seperated,lens fiber layers fractured.Under the EM,cells totally hollowed,mitochondria swelling,myelin figure appeared.RT-PCR examine the expression condition of αsubunit of sodium pump on mRNA level,α1、α2 and α3-isoform are all decreased.2.Digoxin act on lens sodium-pump,under the LM,lens cell oedema,linkage distructed,extensive exfoliation.Under the EM,plasma appeared little half-transparant hollow region,mitochondria swelling and ridge disappeared. RT-PCR examine,α1、α2 and α3-isoform are all decreased.3.Amphotericin B act on lens sodium-pump,under the LM,lens epithelium cells linked tightly,arranged in-line,lens fiber layers arranged tightly and regularily.Under the EM,abbundant cellular organes,exuberant cells function indicated. RT-PCR examine the expression condition of αsubunit of sodium pump on mRNA level,α1 and α3-isoform are increased significantly,demonstrated isoform-specific action.4D-thyroxine act on lens sodium-pump,under the LM,lens plasmalemma integrated,cells arranged tightly and regularily.Under the EM,nucleus fission appeared,desmosome half-desmosome and tensile microfilaments linked the cells. RT-PCR examine,α2 and α3-isoform are increased, also demonstrated isoform-specific action.5.Vitamin E act on lens sodium-pump,under the LM,lens anterior capsular membrane continuous and smooth,epithelium cells tightly linked,lens fiber layers appearede hollow region occasionally.Under the EM,lateral membrane high density belt appeared,abundant nucleolus. RT-PCR examine,onlyα1-isoform are increased, demonstrated significantly isoform-specific action.6.DMSO act on lens sodium-pump,under the LM,lens anterior capsular membrane slightly thicker,cells linkage partly distructed.Under the EM,plasmalemma denaturation,mitochondria swelling.RT-PCR examine,α1、α2 and α3-isoform are all altered slightly and haven't significant meanning.
