放射性

Result: the clinical therapeutic effectof experimental group, was more significant than control group who only underwent external radiation or afterloading intracavitary radiotherapy ,and the adverse reaction of control group exe; the radiation proctitis was more significant than experimental group; compare,58 cases in the experimental group complete the radiotherapy successfully.

结果：58例直肠癌病人采用外照射加后装腔内放疗的治疗效果优于单纯外照射或后装腔内放疗，其临床不良反应，特别是放射性直肠炎，较单纯外照射明显。实验组通过中药保留灌肠清洁肠道、温水坐浴等整体护理，不良反应较未采用整体护理的对照组明显减少， 58例病人均能按计划完成放射治疗。

Results Recurrence and metastasis in surgery, full-dose preoperative intracavitary irradiation, non full-dose preoperative intracavitary and radiotherapy alone groups were 19.8%, 8.1%, 22.2% and 34.6%, respectively. The recurrent rates of vaginal stump were 6.2%, 1.6%, 11.1% and 11.5%, respectively. The rates of proctitis and cystitis in full dose preoperative intracavitary irradiation group were 3.2% and 3.2%, 2.8 and 0.0% in non-full dose preoperative intracavitay irradiation group, and 0.0% and 3.8% in radiotherapy alone group.

结果手术组、术前腔内全量放疗组、术前腔内非全量放疗组及单纯放疗组的总复发转移率分别为19.8％、8.1％、22.2％、34.6％，其中阴道残断复发率分别为6.2％、1.6％、11.1％、11.5％；放疗并发症中，放射性直肠炎、膀胱炎的发生率，术前腔内全量放疗组均为3.2％，术前腔内非全量放疗组分别为2.8％、0.0％，单纯放疗组分别为0.0％、3.8％。

125I seeds interstitial brachytherapy is a new kind of method to treat with malignant tumors. The aim of the experimental research through animals is to investigate the therapeutic effect and the pathological changes on rabbits' VX_2 liver tumor treated with ~(125)I seeds interstitial brachytherapy and percutaneous ethanol injection under CT guidance. We aim to identify the therapeutic effect and the criterion of ~(125)I seeds radiant activity selection, optimize the therapeutic regimen, investigate the tissue damage, its' prothetic time and the relationship between time and dosage effect, and approach to provide fundamental theories for ~(125)I seeds clinical using and arrive at the best dosage range of ~(125)I seeds interstitial brachytherapy. And it can become a new and effective kind of therapies to be applied for the clinical treatment to mid-advanced stage and recurring liver tumor.

放射性粒子组织间植入是肿瘤治疗的一种新方法，本研究通过动物实验探讨CT导引下瘤体内~(125)I粒子植入治疗，以及~(125)I粒子组织间植入联合经皮乙醇注射综合治疗兔VX_2肝转移癌的疗效及其病理基础，确证~(125)I粒子组织间植入治疗肝癌的有效性，确定治疗高度恶性肿瘤的粒子选用标准和最佳治疗方案，同时探索~(125)I粒子在家兔肝脏组织间植入内照射后放射损伤和修复的变化及其时间与剂量效应的关系，提出临床应用~(125)I粒子组织间植入治疗的最佳剂量范围，为该疗法在实际应用中合理化治疗方案的取得提供理论依据，并为临床中晚期及复发肝癌的治疗提供一种新颖、有效的手段。

The suitable concentration of free Ca〓 and the suitable pH for the activity of the tonoplast-bound CDPK was 10μmol/L and 6. 5, respectively. Its active site was provably oriented toward the cytoplasm.

用我们建立的非放射性同位素测定方法和免疫印迹鉴定了液泡膜上存在一种具有钙依赖蛋白激酶活性的膜固有蛋白。

A pilot plant termed Pyrel II has been installed at ENEA laboratories for pyrochemical process studies under inactive conditions.

为了在非放射性条件下研究高温化学工艺，在ENEA实验室建造了一座名为Pyrel-Ⅱ的实验装置。

Copper pyruvaldehyde bis（N -methylthiosemicarbazone） complex, or Cu-PTSM, belonging to a class of neutral, lipophilic complexes ,is a positron emission tomography radiopharmaceutical that can be used to evaluate blood flow in the heart, brain, and tumors without following any side effect .

Cu-PTSM是中性亲脂性复合物，用于PET显像的放射性药物由于该制剂很容易扩散到细胞内，因此注射Cu-PTSM后可以了解心、脑和肿瘤部位的血流灌注状况，它不伴有副反应的发生，且合成比较容易，所以是一种非常有途的新型PET显像剂。
