黑人原发性高血压临床研究——附205例报告

依据世界卫生组织的统计,高血压按纠正年龄后的患病率,非洲黑人最高(25％),白种人其次(17.2％),印度人最低(14.19％)。在成年的黑人人群中,高血压是一种引人注目的疾病。其发生率是很高的。死亡常常是由于脑出血,尿毒症和心力衰竭,而且6％的高血压的黑人合并有糖尿病。高血压作为主要临床表现而病因不明者称为原发性高血压或高血压病。临床所见高血压的绝大多数属于原发性高血压。作者于1983年元月至1985年3月,在南部非洲博茨瓦纳共和国朱必利医院工作期间,诊治了205例确诊为原发性高血压的当地黑人,并对他们进行了临床研究,以探讨黑人高血压病的特殊性及其它的并发症,现报告如下:     

ALTERATION OF CHOLESTEROL SULFATE IN HUMAN SERA DURING THE COURSE OF PREGNANCY

Objective To determine the concentrations of cholesterol sulfate ( CS) in human sera and pla-cental villi during the course of pregnancy. And to analyze its inhibitory activity on thrombin and further characterize the functional significance of CS. Methods The concentrations of CS were determined by thin-layer chromatog-raphy (TLC) on 60 cases of normal pregnant women and 30 cases of normal placental villi. The effect of CS in human sera on the activity of thrombin was analyzed. Results The concentrations of CS in human sera gradually increased from the first to third trimester of gestation with a correlation coefficient of 0. 69, and a correlation between the concentration of CS and weeks of gestation (P <0. 01). CS was also contained in the placental villi, and its concentrations at the second and third trimester of gestations were 4. 7 and 6. 2-fold of that at the first trimester of gestation. CS inhibited the activity of thrombin. Conclusion Placental CS is one of the sources of CS in the serum , pr

先天性胆总管囊性扩张症的诊断与治疗

先天性胆总管囊性扩张症俗称胆总管囊肿,可发生于除胆囊外的肝内、外胆管的任何部位.Caroli 于1958年详细描述了肝内胆管的囊性改变,所以先天性胆总管囊肿等名称已经不能包括此类病的全部,统称为囊性扩张或胆管囊肿为宜.本病好发于婴幼儿,但成年病例仍约占总病例数的1/4.女性发病率高,约为男性的4倍,在西方国家其发病率较低,约为0.01%[1].     

灵芝对应激性溃疡的影响和抗乙酰胆碱作用

灵芝浸膏给小鼠灌胃，每日1．0g／2．0g／kg，连续3d，末次给药后1h，用束缚水浸法造成应激性溃疡。结果表明，灵芝能显著降低溃疡的发生率及减少胃粘膜出血。灵芝拮抗乙酰胆碱对离体肠肌的收缩，IC50为8．5×11-4g／ml。灵芝抑制应激性溃疡的形成，可认为是其对外周副交感神经的阻断作用。     

胆内瘘的诊断与治疗

收治２９例胆内瘘患者，其中胆囊十二指肠瘘８例，胆总管十二指肠瘘６例，胆囊胃瘘６例，其余类型共９例，胆结石与本病有密切关系，同时医源性因素在胆内瘘成因中也不可忽视，手术治疗应掌握适应证。
