为研究草酸钙尿结石期问犬肾功能和肾脏组织结构变化,将10只比格犬随机分为两组,每组5只。按体重(0.13 mL/kg)经头静脉对处理组犬每天注射草酸钾溶液(0.5 mol/L),对照组犬注射等剂量的生理盐水,每天3次,连续注射7 d。观察犬的临床表现,每天采集的血清用于生化检查;在最后一次注射8 h后,用手术方法采取肾脏,通过HE & Pizzolato’s染色和过碘酸.雪夫氏染色(PAS)以及扫描电镜(SEM)与透射电镜(TEM)观察其病理组织结构和超微结构的变化。结果显示,处理组犬。肾有点状出血灶,肾小球呈不同程度的破坏,肾小管中有大量结晶沉积,间质内有炎性细胞浸润;足细胞核皱缩、足突排列紊乱,有明显融合现象,线粒体脊断裂、双层膜结构消失:血清生化检查结果表明肾脏虑过功能下降。因此,草酸钾可导致犬肾小球功能下降,损伤肾小管上皮细胞,草酸钙结晶可在肾小管内大量沉积,并进一步导致肾功能衰退。

Objective： The purpose of this study was to present the dosimetric study and evaluation the dose delivered to the skin tumor by using diode detector with total skin electron therapy （TSET）. Methods： The total skin electron irradiation （TSEI） technique was used to treat ten patients with histological confirmed mycosis fungoides according to the Stanford staging system at the Radiotherapy Department, National Cancer Institute, Cairo University, Egypt. High dose rate electron beams with low electron energy 5 MeV from a Siemens linear accelerator were used for treatment. Diodes were calibrated at TSET distance 300 cm and field size （35 × 35） cm^2. Results： The result of diodes measurements showed the dose to flat surface of the body was within ：1：10 % from the prescribed dose. Special areas of the body such as the perineum ＆ eyelid showed large deviation up to 30% variation from the prescription dose. Conclusion： The diode results of this study will be used as a quality assurance check for all new patients treated with TSET and to compare it to the prescribed dose delivered to the patients. It is recommends to evaluate the diodes measurements for all patients throughout the full treatment cycle and to identify individually the boost dose areas.
