ABSTRACT. Ten boys 9–12 years of age with severe perennial asthma participated in a physical exercise programme lasting 8 months. Pulmonary function and psychological tests were performed before training, immediately after, and one year after the end of the exercise programme. Static lung volumes, flow-volume variables and histamine tolerance were used as indicators of pulmonary function. Ego structure, body image, social development and concentration capacity were used as indicators of personality development. Before the study, the group had high FRC ( p < 0.05) and RV ( p < 0.001), low FEV1 , MEF50 and MEF25 (all p < 0.001) and low histamine tolerance. They showed marked disturbances in their personality development with low scores in psychological variables. During the training period, MEF50 and MEF25 increased slightly ( p < 0.01). Marked improvement was observed in all psychological variables ( p < 0.001). The positive effects remained during the following year. The marked and lasting improvement in personality development was regarded as an essential factor behind the more modest positive clinical and pulmonary function changes. The results emphasize the importance of including exercise programmes in the treatment of children with asthma. 相似文献

ABSTRACT. Hesse B, Rasmussen S, Lund JO, Christensen P, Damkjær Nielsen M. (Department of Clinical Physiology, Glostrup Hospital, and Institute for Experimental Medicine, Copenhagen, Denmark.) Urinary excretion of kallikrein before and after operation for aldosterone-producing adenoma. Urinary kallikrein excretion (UKal), determined by the esterase method, was measured in 10 normotensive volunteers, 10 patients with essential hypertension and in 7 patients with primary aldosteronism before and after operative removal of the adenoma. UKal values were low in 5 of the patients with essential hypertension. Preoperative UKal values in the patients with aldosteronism did not differ significantly from those of the normal subjects, but decreased in all after operation in parallel with changes in urinary excretion of tetrahydroaldosterone and plasma aldosterone concentration. The study supports the assumption of an association between the renal kallikrein-kinin system and the mineralo-corticoid state in man. 相似文献

Abstract. Petersen, S., Christensen, N. C, Jensen, K. M. and Ryssing, E. (Departments of Neonatology and Paediatrics, Rigshospitalet, Copenhagen, and Dumex Ltd., Copenhagen, Denmark). Serum indomethacin concentrations after intravenous administration to preterm infants with patent ductus arteriosus. Acta Paediatr Scand, 70:729,.–Six preterm infants with PDA received 14 treatments with indomethacin 0.2 mg/kg intravenously. Auscultatory and echocardiographic assessment indicated closure of the duct in 2, partial closure in 2, and no effect in 2 infants. The mean serum concentration of indomethacin was: 15 min after the first injection 1314 ng/ml, after 1 hour 970 ng/ml, after 6 hours 718 ng/ml, and after 24 hours 388 ng/ml. The mean half-life of indomethacin in the serum was 20 hours (range 9–50 hours). Side effects in all infants were hyponatraemia, decreased urinary output, decreased urinary sodium excretion, and weight gain. One infant had transient thrombocytopenia and gastrointestinal haemorrhage. By intravenous administration of indomethacin in a dose of 0.2 mg/kg to preterm infants a sufficiently high serum concentration is obtained shortly after the injection. To maintain a high serum concentration for a longer period it is recommended to give a second dose of 0.2 mg/kg after 6 hours and if necessary a third dose of 0.1 mg/kg 24 hours after the first dose. 相似文献

ABSTRACT. A boy with pseudohypoaldosteronism was followed from birth to the age of 7 years. Failure to thrive, vomiting, dehydration, hyponatraemia and urinary sodium loss were prominent findings. Urinary excretion of corticosteroid metabolites was normal. Before treatment, excessively high plasma renin concentration was found, associated with a marked activation of aldosterone secretion. A renal biopsy showed pronounced hypertrophy of the juxtaglomerular apparatus. Persisting metabolic acidosis and an insufficient urinary acidifying capacity suggested the presence of distal renal tubular acidosis. Treatment with sodium bicarbonate and sodium chloride from 19 to 31 months of age resulted in normal growth and normal physical and mental development. The plasma electrolytes were normalized but a pronounced activation of the renin–aldosterone system persisted after therapy, and on sodium restriction this system responded with a considerable further activation. 相似文献

ABSTRACT A simple and practical provocative test is needed for early asymptomatic pheochromocytoma, which is a major risk for patients with multiple endocrine neoplasia type 2 (MEN-2). We measured plasma catecholamines before and after submaximal exercise in 26 MEN-2 gene carriers, eight of whom with asymptomatic pheochromocytoma, nine with medullary thyroid carcinoma and 10 after uni- or bilateral adrenalectomy. Seventeen clinically healthy individuals and 11 patients with neurovegetative lability and symptoms mimicking pheochromocytoma served as controls. Plasma adrenaline, noradrenaline and dopamine increased after excercise except for adrenaline after bilateral adrenalectomy. The post-exercise levels of adrenaline and the adrenalineldopamine ratio were significantly higher in the pheochromocytoma patients compared to the healthy controls and the patients with neurovegetative lability, while the patients with medullary thyroid carcinoma represented an intermediate group with a high probability of developing adrenal tumors. The present method is a physiological test with a high sensitivity and specificity. It is practical and well suited for repeated examinations and seems to be of value for the detection of early pheochromocytoma in MEN-2 patients. Furthermore, the test could be used in the differential diagnosis between pheochromocytoma and neurovegetative lability. 相似文献

Abstract. The effect of captopril on blood pressure (BP) and various components of the renin-angiotensin system was assessed in ten severely hypertensive patients. Captopril acutely reduced the BP with a maximum decrease of 23% at 90–120 min.
Maintenance treatment with captopril alone could not control the BP in any of the patients. Addition of hydrochlorothiazide markedly reduced the BP, while supplementation with propranolol caused no consistent changes.
Three patients attained a supine diastolic blood pressure (SDBP) ≤90 mmHg. Only two patients had a fall in SDBP less than 10 mmHg. One patient stopped because of taste disturbances.
Monitoring the renin-angiotensin system showed suppressed plasma concentrations of angiotensin II and increased levels of angiotensin I and renin, indicating the inhibition of converting enzyme activity. Plasma concentration of renin substrate decreased significantly. This observation has important implications for the methodology of renin assays.
Captropril is an effective alternative in the treatment of hypertensive patients not readily controlled with conventional therapy. 相似文献

ABSTRACT. In 27 mothers to infants with hydrocephalus determinations of platelet antigen Zwa, HLA-typing and ABO-typing were performed in order to evaluate whether undiagnosed alloimmune neonatal thrombocytopenia (AINT) could be an aetiological factor in hydrocephalus. All mothers were Zwa-positive, and the frequency of HLA-antigens and ABO-antigens was as in the normal population. Though sporadic cases of hydrocephalus following AINT are reported, this is not a common cause of intracranial haemorrhage and hydrocephalus. 相似文献

ABSTRACT Nonalcoholic steatohepatitis is a rare complication of obesity with laboratory and histological features indistinguishable from alcoholic hepatitis. Three patients with 50–60% overweight and steatohepatitis are reported. All responded with normalization of the biochemical and/or histological changes after modest weight reduction. 相似文献
