Erythrocyte deformability in acute and chronic kidney failure patients

The authors presented some data on the platelet deforming ability in patients with acute and chronic renal failure treated with hemodialysis. Platelet deformity was studied by means of a proposed method of the filtration of platelet suspension through glass filtering funnels with a porous plate (GOST 9775-69). The deterioration of platelet deformity in patients with uremia and its direct correlation with a degree of nitremia were established. It was assumed that the deterioration of platelet deformity resulted in premature cell destruction and anemia development. Platelet deformity can be used as a test to characterize platelet function in patients with renal failure. The problem of the appropriateness of trental therapy was discussed.     

Predicting weight loss in patients with massive obesity after jejunoileal shunting

Postoperative decrease of the body mass was studied in 105 patients with massive obesity subjected to operation of jejunoileoshunting. Loss of the body mass was proportional to its initial value, inversely proportional to the length of the functioning portion of the ileum. In men the degree of postoperative loss of the body mass was more considerable than in women.     

Bronchial and cardiovascular effects of ocular topical B-antagonists in asthmatic subjects: comparison of timolol, carteolol, and metipranolol

B antagonists eye drops are most effective for the treatment of chronic open angle glaucoma. By this way of administration they have a very good systemic bioavailability. Bronchial, and cardiovascular effects of three of these topicals: timolol, carteolol and metipranolol have been evaluated in three parallel groups of asthmatic patients. The three topics induce bronchoconstriction without significant difference between them, and lower heart rate (sometimes very intensely) whatever the B antagonist studied. From these data, it is recommended to practitioners to follow carefully the rules of administration of B blockers, even in eye drops.     

自体腹白线片修补十二指肠溃疡穿孔(附13例报告)

目的探讨用游离自体腹白线片修补急性十二指肠溃疡穿孔的应用价值。方法从2006年1月至2006年7月对13例用自体腹白线片修补急性十二指肠溃疡穿孔的病人的临床资料和随访情况进行回顾性分析,其中2例穿孔大于2cm2,平均手术时间60分钟,平均失血量20ml,平均住院天数9±1天。结果游离自体腹白线片修补急性十二指肠溃疡穿孔13例均痊愈出院。随访15天至6个月,无手术并发症。结论本方法操作较简单、安全、效果好,其适应症广,是一种可行的新方法。     

On medical screening of civilian candidates for cosmonauts by exposure to the head-to-pelvis acceleration profiles]

The subject of analysis was the data on +3 and +5 Gz tolerance of 130 civilian non-pilot applicants for cosmonauts (men and women, aged 23 to 55) gathered over the past 30 years. Length of the centrifuge arm was 7.25 meters and the total number of primary centrifuge runs was 309. For nearly every second of the applicants (46.7%) acceleration at +5 Gz was an ordeal causing distinct vascular or coronary decompensation. Thus, 29.7% exhibited various combinations of brief visual disturbances, tachycardia, tachypnea, and systolic arterial pressure in the shoulders; in 17%, visual disturbances and/or their precursors were combined with exaggerated cardio-vascular functional parameters, arrhythmia, and serious vegetative disorders. Most of those who had failed to endure the first centrifugation were unable to improve G tolerance during next runs; indeed, they showed negative G-tolerance dynamics. G intolerance grew in significance or was exacerbated by new disorders and their combinations. These results testify against exposure of non-pilot applicants for cosmonauts to +5 G, during the primary medical screening.
