| 1. | There is focal atrophy of tubules seen here to the upper right 右上方可见生精小管的灶状萎缩。 |
| 2. | Microcirculation is the blood circle from arterile to venule 血睾屏障是睾丸内毛细血管与精小管之间存在的屏障结构。 |
| 3. | Study on the tissue structure changes of the seminiferous tubules in the testis of the rat with aging 大鼠生精小管组织结构增龄变化的研究 |
| 4. | Mammalian spermatogenesis is a complex process in which spermatogenic cells undergo differentiating and giving rise to spermatozoa 在曲精小管中的生精细胞经过漫长的分化过程,最终生成精子。 |
| 5. | The capillary vessel were distributed regularly in testis from postnatal i day to postnatal 12 months , and loosely in postnatal 18 months rat , and irregularly in postnatal 24 months rat 从初生组到12月龄组微血管分布很规则;到18月龄组排列变得疏松; 24月龄组生精小管周围的微血管排列不规则。 |
| 6. | Differential display rt - pcr two populations of cells ( dna contains are 2n and 4n ) in seminiferous tubule were sorted , the fragments specifically expressed in 4n cells were obtained and sequenced . 2 差异显示pcr分离曲精小管中的dna含量为2n和4n的细胞群,比较两群细胞的基因表达差异,获取在4n细胞中特异表达的表达序列标签( expressedsequencetagsests ) 。 |
| 7. | The capillary vessel number in every unit area increased and the microvascular wall incrassated gradually with aging . the number ratio between capillary vessels and seminiferous tubules were on the trend of increase from 3 weeks to 3 months and decrease from 3 months to 12 months 随着增龄,单位面积内微血管数目逐渐增多;管壁也明显增厚;微血管数与生精小管数的比值从初生后到3月龄逐渐增大,从3月龄到24月龄呈减小的趋势。 |
| 8. | To observe tsarg2 fusion protein expression in mammalian cell , pegfp - nl / tsarg2 fusion plasmid was constructed and transiently introduced into cos7 cell by liposome transfection . under the fluorescence microscope , the green fluorescence produced by pegfp - nl / rsarg2 was detected on the nucleus of cos7 cells after 24 hours post transfection , while the fluorescence produced by pegfp - nl was detected through the cells 同时将21大、 35天、 49大、 280天小鼠睾丸进行组织石蜡切片,结果表明小鼠翠丸在第21天可见精子细胞,到第35天,精子生成的最后阶段开始发生,部分牛精小管中可见少量成熟的精于。 |
| 9. | 4 . influence of no on microvascular permeability : specimens from postnatal 1 day showed little immunoreactivity for enos . in contrast , blood vessel endothelium and leydig cells and spermatids in postnatal 3 weeks testes were strongly expressed enos . the number of positive blood vessel endothelium , leydig cells and spermatids in postnatal 3 months was conspicuously increased 饱及枯j代细胞均出现了阳性表达: 3月龄组生精小管靠近若腔的精r细胞出现enos阳性,阳性血管内皮细胞数目增多显著: 12月到24月龄阳性l阳乍今内皮细胞数i ] ‘ . ‘增多的趋势。 |
| 10. | Then the arterile eminted intertubular capillaries and peritubular capillaries forming rope - ladder - like pattems . then the venule were collected and became testis veins , then mass into rete venosum , finally some venule formed pampiniform plexus and others entered into varicosity . 3 . changes or testicular microvascular architecture : testicular capillary vessel formed intertubular capillaries and peritubular capillaries . but donot formed rope - ladder - like patterns capillary net in postnatal 3 weeks . there were rope - ladder - like patterns capillary nets around seminiferous tubules in postnatal 3 and 12 months 微血管构筑的增龄变化: 3周龄组睾丸动脉在实质内已形成了管周微动脉和管间微静脉,但绳梯状的毛细血管网尚未形成; 3月龄组与12月龄组微血管构筑呈中文摘要现定的构烈特点,在生精小管周围形成绳梯状的毛细血管网: 18月与24月龄组苹丸萎缩,微而管构筑变得不很规则。 |
