Indices of the body's neurohumoral activity and hemodynamic types in hypertension

A study of neurohumoral parameters in patients with essential hypertension and different hemodynamic types demonstrated different patterns of hormonal change in patients with hyperkinetic, eukinetic and hypokinetic hypertension. Elevated blood tri-iodothyronine and thyroxine, seen in patients with hyperkinetic hemodynamic type, and increased catecholamine excretion in patients with hypokinetic hemodynamics may be indicative of the pathogenetic significance of the hormones in question for the formation of respective variants of essential hypertension.     

APPLICATION OF ACUPOINT-INJECTION THERAPY TO PAIN SYNDROME: CLINICAL ANALYSIS OF 250 CASES

In this paper,250 cases of headache,shoulder pain,lumbago and leg pain weretreated with 20％Angelicae Sinensis mixed with Vitamine B_(12) point-injection therapy.The total effective rate was 95.2％and in which the cure rate was 53.6％.Authors have found a close correlation between the effectiveness and the duration of disease.     

Binswanger's disease in the absence of chronic arterial hypertension

Summary The cerebral changes are described in a woman of 54 who suffered from Binswanger's encephalopathy: there were no signs or symptoms of chronic arterial hypertension. The disease presented as dementia of about 3 years duration. Computed tomography of the brain 2. 5 years before her death showed bilateral widespread hypodense lesions in the cerebral white matter. She died of an asthmatic attack. Autopsy disclosed extensive bilateral degeneration of the central white matter, lacunes and gliosis. Severe obliterative arteriolosclerosis occurred in the meningeal vessels and those supplying the affected parts of the brain. Light microscopy showed that the most severe lesions occurred in the arterioles. Immunohistochemistry demonstrated profound extravasation of plasma proteins chiefly albumin, indicating dysfunction of the blood-brain barrier. Thus, the lesions characteristic of Binswanger's encephalopathy may develop in the absence of chronic arterial hypertension. Additional pathogenic factors, possibly genetic predisposition to vascular injury may play a role in the development of this condition.Supported by grants from the Swedish Medical Research Council, Project No 12X-03020 and 1987 Års Stiftelse för Strokeforskning     

川芎嗪和维拉帕米对缺血性急性肾衰初期保护效应的实验研究

１８只犬切除右肾，钳夹左肾动脉６０分的肾缺血模型，再灌注５小时。将动物随机分成对照组、川芎嗪组及维拉帕米组。观察尿量、菊糖清除率、利钠指数、平均动脉压及心率；再灌注５小时取肾组织作形态学检查。结果显示川芎嗪对肾功能及形态有保护作用，维拉帕米则无此作用，提示在手术中有肾缺血时以川芎嗪作为肾保护药物优于维拉帕米。     

Functional changes of myocardial contraction and relaxation in hypertension patients as affected by reflexotherapy

49 patients with initial stages of essential hypertension (EH) were investigated using phase systole analysis and echocardiography during acupuncture (reflexotherapy) treatment. It was established that even at the initial stages of EH increasing of myocardial mass and the disturbances of contractile and diastolic activity of myocardium take place. As a result of acupuncture a stable hypotensive effect, improvement or normalization of contractile function and diastolic values, a decrease of energy loss, reversal of myocardial hypertrophy were achieved. It is the decrease of sympathetic influences on the circulation system that plays an important part in the onset of these positive changes.     

Triploid origin of the gibel carp as revealed by 5S rDNA localization and chromosome painting

5S ribosomal DNA (rDNA) was isolated and sequenced from the gibel carp Carassius auratus gibelio with 162 chromosomes and crucian carp Carassius auratus with 100 chromosomes, and fluorescent probes for chromosome localization were prepared to ascertain the ploidy origin and evolutionary relationship between the two species. Using fluorescence in-situ hybridization (FISH), major 5S rDNA signals were localized to the short arms of three subtelocentric chromosomes in the gibel carp and to the short arms of two subtelocentrics in the crucian carp. In addition, some minor signals were detected on other chromosomes of both species. Simultaneously, six chromosomes were microdissected from the gibel carp metaphase spreads using glass needles, and the isolated chromosomes were amplified in vitro by degenerate oligonucleotide primed-polymerase chain reaction (DOP-PCR). Significantly, when the DOP-PCR-generated probes prepared from each single chromosome were hybridized, three same-sized chromosomes were painted in each gibel carp metaphase, whereas only two painted chromosomes were observed in each crucian carp metaphase spread. The data indicate that gibel carp is of triploid origin in comparison with diploid crucian carp.     

中国古代的男性生殖崇拜

当男性在社会生产中的地位日趋重要，并且人们开始将生殖与男性相联系时，男阴便受到崇拜，古人常以鸟作为男性生殖器的像征，这或许是因为鸟头和颈具有与男性生殖器有相似的伸缩功能的缘故，
