| 中文摘要: |
| 贝氏高原鳅(Triplophysa bleekeri)泌尿系统由中肾、输尿管、膀胱构成。头肾极小。中肾组织在前中后三部分中无明显差异,也无功能分区的现象。成体中肾组织中除大量成熟肾单位外,还发现少量发生中的肾单位和少量解体中的肾单位。成熟肾单位的肾小体为典型的淡水真骨鱼类肾小体,肾小管分化为第一近端小管(PⅠ)、第二近端小管(PⅡ)和远端小管(D)。PⅠ、PⅡ段上皮为单层柱状上皮,上皮细胞管腔游离面具有丰富的刷状缘和9+2式纤毛。D段为单层矮柱状上皮或单层立方上皮,管腔游离面无刷状缘,也无纤毛。输尿管前、后段组织结构有明显差异。膀胱为不发达的输尿管膀胱。斯坦尼斯小体2枚。 |
| 英文摘要: |
| The urinary system is consisted of kidney,ureter and bladder in Triplophysa bleekeri.The head kidney is small in size.The kidney includes renal corpuscle,renal tubules and lymphoid tissue,and there is no differentiation between cortex and medulla.Morphologically,the renal tubule was differentiated into distinct segments:first and second proximal tubules and distal tubule,without cervical segment.There is evident difference in ureter’s organizational structure between forepart and rear-end.The bladder is in undeveloped tubular form.Two Stanniuse corpuscles are observed. |
