combined active and passive immunotherapy in honeybee-sting allergy.five honeybee sting-allergic patients in whom bee venom immunotherapy (vit) had previously been stopped because of repeated allergic side effects (se) were resubmitted to bee vit after pretreatment with beekeeper gammaglobulin. the tolerated bee venom dose was increased five to 800 times after this passive immunotherapy, and the maintenance dose of 100 micrograms of honeybee venom (bv) was reached in all patients after 6 to 15 days of a rush hyposensitization. the igg response to bv was not supp ...20133722631
[multifocal hydatid cysts in children].from 1981 to 1983, 112 children have been operated on for hydatidosis, 26 of them presented multifocal hydatid cysts. in half cases the lung was affected, in association with an abdominal affect. in 6 cases it was a bilateral pulmonary localisation. the check-up is essentially with two exams: thoracal radiology, front and side view; and abdominal echography. the hydatic serology confirms the parasitic origin. 40 surgical operations have been necessary for 21 children carried 171 hydatid cysts. t ...20133719886
absence of role of endothelium in the response of isolated porcine coronary arteries to acetylcholine.isolated precontracted arteries of various vascular beds relax in response to acetylcholine only if the endothelium is present. one explanation for this is that this drug stimulates the endothelial cells to release a vasodilator substance that in turn relaxes the underlying smooth muscle. to determine whether this mechanism is concerned also in the acetylcholine contraction of isolated porcine coronary arteries transverse strips of the extramural part of the left circumflex artery were used for ...19863719611
treatment of idiopathic hypercalciuria with indapamide.twenty-six patients with idiopathic hypercalciuria (urine calcium level greater than 300 mg/24 h [7.5 mmol/d]) were treated with indapamide (a nonthiazide diuretic), 2.5 mg/d for 3 consecutive months. a mean decrease in urine calcium levels of 52% was noted (p less than 0.05). when therapy with indapamide was stopped, the calcium levels returned to pretherapy values. the effect of indapamide on urine calcium levels was similar to that of hydrochlorothiazide in 10 patients who were receiving the ...20133719496
