This paper presents the results of observation by means of histochemical, electron microscope cytochemical and biochemical techniques designed to investigate the effect of gossypol on the Na-K-ATPase activity in the renal tubules and musculus gastrocnemius of animals. The results obtained are as follows:

本文报道用光镜组织化学、电镜细胞化学定位和生化测定的方法分析棉酚对动物肾小管及腓肠肌Na-K-ATP酶活性的影响。实验结果表明: 1.细胞化学反应显示了Na-K-ATP酶定位于腓肠肌肌膜,肾远曲小管的基底膜和细胞反褶膜以及髓袢升支的细胞膜上。肾集合管与近曲小管的基底膜及细胞反褶膜上亦有轻微的阳性反应。 2.抗生育剂量棉酚(10毫克/公斤,20毫克/公斤,30毫克/公斤)对大鼠和豚鼠的Na-K-ATP酶组化反应未见有明显的影响,雄猴实验亦得到类似结果。但当棉酚剂量加大到60毫克/公斤时,大鼠和豚鼠的肾小管及腓肠肌的Na-K-ATP酶反应均明显减弱。豚鼠肾细胞膜酶活性的生化定量测定结果亦表明棉酚对肾的Na-K-ATP酶活性有明显的抑制作用。这一结果表明棉酚可引起Na-K-ATP酶活性的降减,而且与剂量成正相关,为棉酚引起肾性失钾的可能性提供了实验依据。本文对细胞膜Na-K-ATP酶细胞化学定位、酶活性以及棉酚对该酶抑制作用的可能机理进行了讨论。

Collecting duct carcinoma of the kidney is rare and its biological behavior is not well known. 5 cases of collecting duct carcinoma(3 males and 2 females,age 41~67 years)were identified in the last 4 years.The clinical,pathologic and immunohistochemical characteristics of these tumors were presented.The most common symptoms were hematuria, fatigue,marasmus and low fever.4 patients underwent radical nephrectomy,of those 3 have been alive without evidence of recurrence for 3 months,2 and 2.5 years,respectively,whereas 1 died of lung metastasis 14 months after operation.One patient was submitted to simple nephrectomy because of extensive regional nodal invasion and bone metastasis was noted 2 months afterwards.Grossly the tumor had a whitish appearance with the bulk of the mass located in the renal medulla.Histologic examination showed prominent tubulo-papillary structures.Marked desmoplastic reaction was noted and atypical hyperplastic changes were found in the adjacent collecting ducts.Immunohistochemical studies revealed positivity with antibodies to epithelial membrane antigen,high molecular weight cytokeratins and peanut agglutinin,With a review of the literature some issues concerning the diagnosis and management of these tumors were discussed.

肾集合管癌少见,其生物学行为尚不十分清楚。我们在近4年间收治5例,男3例,女2例,年龄41~67岁。主要临床表现为血尿、消瘦、低热。4例行根治性肾切除术,3例分别经3个月,2、2.5年随访无复发,l例术后1年2个月死于肺转移。1例因肾门、腔静脉旁淋巴结广泛受累仅作姑息性肾切除,术后2个月出现骨转移。病理所见:肿瘤灰白,位于髓质,镜检呈腺管乳头状结构,间质丰富,邻近集合管异型增生。免疫组化检查高分子细胞角蛋白,花生凝集素及上皮细胞膜抗原均阳性。结合文献对集合管癌的若干诊断和治疗问题进行讨论。

The epithelial cells of collecting tutules of tats different age were studied by TEM image analysor in this study. The results showed,(1) The nueleoplasmic index (NP) of the epithelial cells of collecting tubules in the newborn group was significantly higher than that of the young and adult groups, but no difference was found between the young and adult groups (2)The cell morphology including cell junction and plasma membrane infolding was greatly different between the newborn and the othet two groups.

本文利用透射电镜和图象分析仪对三组不同年龄大鼠肾集合管上皮细胞进行了观察和分析。结果表明:(1)初生组大鼠肾集合管上皮细胞的核质比明显大于青年组和成年组,而青年组与成年组的核质比则无明显差别;(2)细胞形态包括细胞间连接、细胞基底部的质膜内褶等方面,初生组与青年组、成年组都有较大的变化。
