The variation of plastid DNA contents in terms of fluorescere intensities in three kinds of calli producing green and albino pollen plants as well as regenerated albinos exhibits respectively a characteristic regularity of its own. Together with the electron microscopic observation of leaf plastid structure and the result of chlorophyll determination, it is considered that such regularity in variation of ptDNA contents may be the result of their successive deletions during the course of dedifferentiation of pollen cells and the serious deletion of predominant pvDNAs leads to the formation of pollen albinos. It is likely that the successive deletions of ptDNAs are not random in nature but reflect the sequence organization of ptDNA, and the potentiality to suffer deletions of such kind may be of general significance. The characteristics of pollen albinos are mainly directed by the predominant ptDNAs, the minor pt DNAs however still possess some effects.

以质体为单位的愈伤组织ptDNA的荧光强度变化显示出了特有的规律性。结合光培养花粉白苗叶片质体结构的电镜观察及叶绿素等色素的测定等,这种规律性似提示花粉白苗的ptDNA由于发生了相继缺失而显示出高度异质性,花粉白苗的形成则在于其占优势ptDNA的严重缺失。花粉白苗ptDNA的这种相继缺失不是随机的,似反映了ptDNA顺序组织上的特点。故ptDNA发生缺失的潜在可能性具有普遍意义,它与父系细胞质体类核的消失存在着并行关系。花粉白苗的占优势ptDNA指导了植株的性状,而次要ptDNA亦在较小程度上显示出影响。

The effects on variation of different concentration of the extro-hormone in the media,generations of subculture in vitro and the different explants from the three varietied or lines wereprimarily studied. The results showed that No. 631 of banana was stabler than Williams under thesame conditions of culture. The line Taiwan & was similar stablity with No. 631. When the generations of subculture was increased, the rate of variation was obviously enhanced, also.The tests of proportion of hormones showed IBA: BA =0.5: 4.0 (mg / L), was the fairest. Assoon as the proportion was 2.0: 10.0 (mg / L), the rate of variations was the highest. The numberof chromosomes in the cell of root tip from the variable seedling in the fields were increased or decreased because the generations of subculture was too much.

本文初步研究了香蕉离体培养中,培养基内不同激素浓度、继代培养数,以及3个品种(品系)对试管苗变异的影响。结果表明:631和台湾8号比威廉斯(Williams)稳定,培养条件相同,培养代数多时,变异率明显提高。外源激素的配比试验表明:IBA∶BA为0.5∶4.0(mg/L)为最佳配方,当IBA∶BA达到2.0∶10(mg/L)时,异常苗发生率最高。用田间变异株根尖细胞染色体观察结果,发现其染色体数不是增多就是严重缺失。变异株的过氧化物酶同工酶酶谱经电泳分析,表明在迁移率为0.7处的一条带纹消失,而正常对照苗则稳定存在。

Objective The aim of this study was to investigate the role of diphenylhydantoin(DPH) in protection of brain against acute hypoxia. Methods Seventy two Wistar rats served as subjects. They were divided into 6 groups:3 experimental and 3 control(a. stayed at the ground level,b. underwent 7 500 m hypoxia for 1 h and c.for 2 h).To the experimentals diphenylhydantoin (40 mg/kg) was given ip before hypoxic exposure.The contents of dopamine(DA), noradrenaline(NA) and 5 hydroxytrytamine(5 HT) in the brain tissue...

Objective The aim of this study was to investigate the role of diphenylhydantoin(DPH) in protection of brain against acute hypoxia. Methods Seventy two Wistar rats served as subjects. They were divided into 6 groups:3 experimental and 3 control(a. stayed at the ground level,b. underwent 7 500 m hypoxia for 1 h and c.for 2 h).To the experimentals diphenylhydantoin (40 mg/kg) was given ip before hypoxic exposure.The contents of dopamine(DA), noradrenaline(NA) and 5 hydroxytrytamine(5 HT) in the brain tissue were measured by fluoresent method.The histomorphological changes of rat brain were examined by electronmicroscope. Results In experiment als underwent hypoxia for 1 h and 2 h the DA and 5 HT contents of brain tissue were significantly higher than those stayed at ground level.NE content of the rats,underwent 1 h hypoxia was significantly lowered. The differences of DA,NA and 5 HT levels among 3 control groups were nonsignificant.The histomorphological changes of experimental groups were nonsignificant,while swelling of brain cells disappearing of mitochondrial granuals and deformation of nucleus were observed in the control groups underwent hypoxia for 1 h and 2 h. Conclusion It is suggested that DPH is of value in protection of brain against hypoxia,and DA,NA and 5 HT may be involved in the development of tolerance of brain cells to acute hypoxia.

目的探讨苯妥英钠(Diphenylhydantoin,DPH)在急性缺氧条件下的脑保护作用。方法给大鼠应用DPH,用荧光分光法检测其在低压舱模拟升空7.5km后1h、2h的脑匀浆单胺递质含量,同时观察脑细胞形态学改变。结果DPH实验组在缺氧1h及2h时脑多巴胺和5-羟色胺含量升高(P<0.05),而脑去甲肾上腺素在缺氧1h时降低(P<0.05),缺氧2h恢复正常。电镜形态学观察,低压缺氧条件下对照组大鼠脑细胞水肿,线粒体嵴严重缺失,细胞核明显变形;应用DPH的实验组细胞形态基本正常。结论给大鼠应用苯妥英钠后,在急性缺氧条件下,动物脑单胺递质含量的变化可能与缺氧适应或耐受的形成有关。
