研究麦冬块根87Sr/86Sr同位素比值在麦冬原产地溯源中的应用.利用热电离质谱检测浙江和四川麦冬样本的87 Sr/86 Sr同位素比值,对不同产地麦冬样本的87 Sr/86 Sr同位素比值进行了置信区间分析和方差分析.结果表明,产自浙江和四川的麦冬样本87 Sr/86 Sr同位素比值具有显著性差异.麦冬87 Sr/86 Sr同位素比值与原产地有显著相关特征,可以利用TIMS测定麦冬的87 Sr/86 Sr同位素比值并进行原产地溯源.

瘫痪是指骨骼肌随意运动能力减弱或丧失.后躯瘫痪俗称“腰痿”,主要病状为腰部僵硬,后躯运动不灵活,局部反应性降低,不愿起立,若强迫行走,则运步迟滞.轻度麻痹时,预后良好;若陷入严重麻痹,预后慎重[1].引起犬后躯瘫痪的原因有很多:肥胖压迫神经、外力作用引起脊髓挫伤、椎间盘突出致脊髓受压等,常发于贵宾、京巴、腊肠、比格等小型犬[2].
为了给东北虎细小病毒感染病例的临床诊断和治疗提供借鉴,本试验通过临床诊断、血常规检查、病原PCR检测、影像学检查、组织器官剖检、病理组织切片观察等方法,分析1例东北虎细小病毒群发感染病例,并采用抗病毒、调节免疫、止血止吐对症治疗、控制继发感染、营养支持和调节电解质平衡等疗法对该东北虎及其他患病东北虎大群实施治疗.结果 表明,通过及时确诊、综合治疗、细心护理,能促进感染细小病毒的东北虎群尽早恢复正常,病情得到有效控制.
淋证的主要症状表现为小便频急、淋漓不尽、尿道涩痛、小腹拘急、痛引腰腹等,类似于西医概念中的急、慢性尿路感染,泌尿系结石,前列腺炎,膀胱炎,乳糜尿等疾病的症状.淋证最早见于黄帝内经《素问.六元正纪大论》中,“淋者,淋漓不尽,如雨淋而下;閟,通秘,不通之意也.”指出了淋证既有可能是小便淋漓不畅,又有可能是闭阻不通之象.淋证主要由情志失调、饮食不节、禀赋不足、劳伤过度、久病缠身等因素引起,造成湿热蕴结下焦,肾与膀胱气化不利[1].

皮肤无力(Cutaneous asthenia),同义词Ehlers-Danlos综合征,是一种罕见的因遗传性胶原蛋白生成障碍引起的结缔组织发育不全综合征.患病特点为幼年发病,皮肤过于脆弱和过度伸展,皮肤极易撕裂.由于患猫精神、体格、血常规和生化等均正常,表现出的症状以皮肤抓伤为主,容易被诊断为普通的皮肤病和外伤,延误治疗和松懈管理,导致频繁受伤.可通过病史、伤口特点、伤口愈合进程、皮肤延展性指数和组织病理学检查等作出诊断.暂无明确有效的治愈方法,良好的管理可以使患猫达到正常寿命,目前国内该病的病例报道罕
