A case associating primary parathyroid hyperfunction with hyperthyroidism]

A case of rare association of hyperparathyroidism with fully developed hyperthyroidism appearing in a woman 23 years old with advanced generalized cystic fibrosis has been presented.     

Combined clofibrate-chlorpropamide therapy in diabetes insipidus complicated with diabetes mellitus]

The authors observed the incidence of diabetes mellitus and diabetes insipidus in three cases. The combined clofibrat-chlorpropamide treatment proved to be successful. They succeeded in ceasing the daily insuline by giving the two drugs together. The daily diuresis diminished considerably in all three patients. The authors advise the combined clofibrat-chlorpropamide treatment in the incidence of the two diseases. This is especially reasonable when there is a disturbance in the lipoid metabolism.     

Post receptor activation of lipolysis in starvation, diabetes mellitus and hyperthyroidism

Activation of lipolysis by cyclic AMP in conditions with accelerated lipid mobilization was examined in subcutaneous adipose tissue incubated in vitro. In (a) 16 obese patients before and during therapeutic starvation, (b) 18 diabetics before and after antidiabetic treatment and (c) 11 hyperthyroid patients before and after anti-thyroid treatment, a positive correlation was found between stimulation of basal cyclic AMP accumulation and stimulation of basal glycerol release using either isopropyl noradrenaline or noradrenaline (r = 0.6-0.9). During antidiabetic treatment stimulation of lipolysis increased in relation to that of cyclic AMP accumulation (F = 10.1, p less than 0.01), whereas during antithyroid therapy there was a decrease (F = 95.2, p less than 0.01). Starvation did not alter the relationship between lipolysis and cyclic AMP in hypogastric adipose tissue whereas in femoral tissue stimulation of lipolysis decreased in relation to that of cyclic AMP accumulation (F = 9.6, p less than 0.01). It is concluded that the amount of cyclic AMP needed to promote lipolysis is increased during starvation and in diabetes mellitus but is decreased in hyperthyroidism. From the studies during starvation it appears that regional differences in the post-receptor activation of lipolysis exist in human adipose tissue.     

糖尿病下肢溃疡影响因素分析及治疗方法

目的探讨糖尿病下肢溃疡的原因和治疗方法。方法回顾总结我院近年来急诊科临床收治的糖尿病并发下肢溃疡患者12例,全部病例均使用胰岛素控制血糖、抗生素抗感染、静脉滴注活血化瘀的中药、常规局部换药并结合使用具有去腐、生肌、消炎作用的中药膏剂进行治疗,同时对患者进行糖尿病相关知识的教育和自我护理技能培训。结果全部病人均治愈出院,其中截趾术后伤口愈合出院1例,点状邮票植皮后伤口愈合1例,经换药伤口愈合10例。随访期间全部病例溃疡未复发。结论糖尿病下肢溃疡是由血管、神经、感染等多重因素造成的。对糖尿病并发下肢溃疡患者采用多种方法综合治疗可以取得较好的疗效,同时强调重视糖尿病的管理和教育。     

Single crystals of amylose with a low degree of polymerization

Single crystals of amylose with a low degree of polymerization were prepared from dilute solution in water or mixtures of water and ethanol. Depending on the concentration of ethanol used, three different polymorphs resulted. From pure water amylose B was obtained and, respectively, from 15% (v/v) ethanol, amylose A, and from 40% (v/v) ethanol, V amylose. The crystals were studied by electron diffraction after quench-freezing and the crystallographic parameters were compared with those already reported in the literature.     

比索洛尔联合甲巯咪唑治疗甲状腺功能亢进合并快速心律失常疗效观察

目的探讨比索洛尔与甲巯咪唑对甲状腺功能亢进(甲亢)合并快速心律失常的临床治疗效果。方法选择2015年1~12月在我院接受治疗的甲亢合并快速心律失常患者78例,随机分为对照组和观察组各39例,对照组给予甲巯咪唑单药治疗,观察组给予比索洛尔联合甲巯咪唑治疗,比较两组临床疗效。结果观察组治疗有效率为92.31%,显著高于对照组的74.36%(χ2=7.65,P0.05);观察组治疗后的FT3、FT4、TSH均显著低于对照组,且观察组的FT3/FT4相对更高(t=10.34、13.50、13.43、12.54,均P0.05);观察组的不良事件发生率和不良反应发生率均显著低于对照组(χ2=5.43、6.17,P0.05)。结论比索洛尔联合甲巯咪唑治疗甲亢合并快速心律失常患者的效果确切,能有效改善患者症状,降低不良事件发生率,具有较高的推广应用价值。     

Hydrocelluloses with low degree of polymerisation from liquid ammonia treated cellulose

The heterogeneous hydrolytic degradation of cellulose after treatment with liquid ammonia has been studied. The level off degree of polymerisation (LODP) of liquid ammonia treated (LAT) linters is reached after 3 h when hydrolysed in hydrochloric acid (6.5 mol/l) at 60 °C. The hydrocelluloses were characterized as trimethylsilyl derivatives and as tricarbanilates. LODPs of non-activated celluloses were in the range from 55 to 77, while LAT celluloses had LODPs between 27 and 39. Trimethylsilyl derivatives and tricarbanilates gave almost identical elution curves in size exclusion chromatography indicating comparable hydrodynamic volumes. Glass transition temperatures of trimethylsilyl celluloses with DPs from 27 to 39 were found to be lower than those of the derivatives of the parent celluloses (Avicel, cotton linters) and showed a dependence on molar mass indicating that oligomeric celluloses are obtained by the method reported. Treatment of cellulose in aqueous ammonia was less efficient than liquid ammonia treatment.
