Tubulogensis

For this strategy to be effective,however,cell biological information about tubule development within the diseased organ is needed.

但是,要使这种治疗方案行之有效,需要了解关于患病肾脏肾小管发育的细胞生物学信息。

1 mg/kg Cd~(2+) solution,no distinct change was observed in epithelia of the renal tubules,for the doses of 0.

1 mg/kg的Cd2+溶液注射20次后,肾小管上皮细胞未发生明显变化;以每次剂量为0。

Methods: Paraffin (7 μm in thickness) and methacrylate resin (25 μm) embedded renal sections were observed using 40× objective lens and 100× oil lens, respectively, and the volume fractions and diameters of the renal tubules and the tubule nuclei were estimated with stereological methods.

方法 :分别用高倍镜 (40×物镜 )和油镜 (10 0× )观察石蜡 (7μm厚 )和甲基丙烯酸树脂 (2 5 μm厚 )包埋的肾脏切片 ,利用体视学方法测量肾小管的体积分数和直径以及肾小管细胞核的体积分数和直径。

Objective:To examine the effect of mercuric chloride toxicosis on enzyme cytochemistry of renal tubules epithelil cells in rats.

目的 :检测氯化汞中毒对肾小管上皮细胞酶化学的影响。

Metrological study of spermatozoon in seminiferous tubule of rats after artificial cryptorchism;

实验性隐睾术后大鼠生精小管内精子的计量学研究

After 80days,the weight of testis,the intradiameter of seminiferous tubules,the .

结果:800mg/kg PNS剂量组睾丸系数、生精小管直径、血清TNF-α和T含量与模型组比较,差异有统计学意义,光镜所见睾丸组织结构接近正常对照组形态;200mg/kg PNS剂量组和模型组生精上皮坏死、脱落,睾丸间质水肿,不同程度炎性细胞增生浸润。

Methods: Segments of seminiferous tubules were obtained from the adult male SD rats,at stages XIII~I of meiosis,and the interstitial cells of the same testis were isolated under the stereomicroscope.

目的:比较成年大鼠睾丸生精小管处于减数分裂期的发育片段和睾丸间质细胞所表达基因的差异,初步筛选出与减数分裂相关的基因,为进一步研究减数分裂相关基因对精子发生的调控奠定基础。
