One of the factors of the successful military career guidance Cadet schools students is preserving and promoting their health. Medical support of children and adolescents aged 10-17 years should include the full range of medical and preventive measures defined for this group. The state of providing outpatient care for pupils at the Cadet School in St. Petersburg was studied. These results show that full medical care in accordance with the standards can be based only on children's health clinics. It is important that the organization of medical support pupils cadet schools should be cooperate with civilian health care. 相似文献

ESR-spectrometry was used to investigate radiation-induced paramagnetic centers in enamel of mammals: carnivores (polar bear and fox), ungulates (reindeer, European bison, moose), and man. Values at half the microwave power saturation of the radiation signal, P1/2, evaluated at room temperature, was found to range from 16 to 26 mW for animals and man. A new approach to discrimination of the radiation induced signal from the total ESR spectrum of reindeer enamel is proposed. ‘Dose-response’ dependencies of enamel of different species mammals were measured within the dose range from 0.48 up to 10.08 Gy. Estimations of ‘radiosensitivity’ enamel of carnivores and ungulates showed good agreement with radiosensitivity enamel of man by ESR method. 相似文献

海马头部浅沟消失对海马硬化诊断价值的探讨 总被引:3,自引:0,他引:3
目的 探讨海马头部浅沟消失对海马硬化的诊断价值。方法 对 18例经组织学检查证实的海马硬化患者的MRI检查资料和 18例年龄相匹配的对照组进行回顾性分析 ,观察海马头部浅沟的显示情况、海马头部大小和信号改变。结果 18例海马硬化患者中 ,16例硬化侧海马头部浅沟消失 ,1例硬化侧海马头部浅沟明显变浅 ,几乎消失 ,1例硬化侧海马头部浅沟存在。硬化侧海马头部均有萎缩 ,并在T2 WI和液体衰减恢复 (FLAIR)成像呈高信号。海马头部浅沟消失对海马硬化诊断的敏感性为 88.9% ,特异性为 10 0 %。结论 海马头部浅沟消失是诊断海马硬化的一个可靠征象 ,结合患侧海马有萎缩性改变和T2 加权成像信号增高 ,可肯定诊断海马硬化。 相似文献

肝癌转移机制研究进展 总被引:1,自引:0,他引:1
肝癌细胞的侵袭和转移是肝癌治疗失败和患者致死的主要原因,因此,了解肝癌侵袭转移的相关机制十分重要。肿瘤转移是一个多步骤的复杂的生物学过程,多个因素参与了肿瘤转移的调控,癌基因的表达上调、抑癌基因的失活、免疫基因的失调、肿瘤细胞间粘附作用的丧失、新生血管的形成、蛋白水解酶的合成、细胞的迁移能力增强、肿瘤细胞和基底膜的粘附等等,都是促进肿瘤转移复发的重要因素。 相似文献

军队人员智齿预防性拔除的评价 总被引:2,自引:0,他引:2
智齿,在口腔临床被称为第3磨牙,是口腔中最后萌出的牙齿,上下左右各一颗(亦有先天缺失的情况),萌出年龄大约18-30岁,常常引起冠周炎及间隙感染而需要拔除,临床上有许多没有症状的智齿还能引起相邻的第2磨牙的龋齿、牙列拥挤错乱及颞颌关节紊乱等相关疾病。军队人员的主要年龄段正是智齿萌出的时期,现就军队人员是否应该智齿预防性拔除进行评价。 相似文献

Analysis of the results of the international comparison of activity measurements of a solution of Fe
The results of an international comparison of activity measurements of a solution of 55Fe organized by the BIPM in 2005 are reported and analysed. This exercise, which follows the procedures of the CIPM mutual recognition arrangement to update older comparisons, is a renewal of the comparison organized by the BIPM that took place in 1978. A EUROMET comparison was organized in 1996 specifically to compare activity measurements of a 55Fe solution by means of liquid-scintillation techniques. Results of these three comparisons are presented and discussed in this paper.
The radionuclide solution was provided by the NPL, which also distributed the samples to the participants. The activity of the ampoules was measured by 16 laboratories using 12 methods producing 25 results. Some general considerations on uncertainty assessments pertaining to the different techniques used are drawn. The outcome of four different estimators is compared from which the presence of at least one outlier can be confirmed. Further measurements should be made to try to reduce the discrepancy between the results. To date the outcome of the present comparison does not show an improvement to that of the 1996 comparison. 相似文献

A new method of non-surgical treatment of varicocele syndrome is described: it consists in sclerotherapy of spermatic vein by trans-femoral percutaneous catheterization with balloon-catheters. In 8 cases venous thrombosis has been induced by direct electric clotting. The techniques and a 6 months follow-up are discussed. It is pointed out that this procedure should be considered as the method of choice for tubular lesions and sub-fertility prophylaxis in young people and in childhood. 相似文献
