[Human basophil degranulation test (HBDT) for diagnosis of respiratory allergic disorders. A study of eighty-four HDBT performed in forty-seven patients (author's transl)].

The HBDT uses basophils of patients with respiratory allergic disorders. In this simple method the basophils are stained by toluidine blue and the erythrocytes are destroyed. The basophils are then exposed to solutions containing different concentrations of the antigen. The basophil degranulation rate in response to a given antigen can be determined. The test is positive if the degranulation rate is over 50% and negative if the rate is under 30%. Our clinical study induces 47 patients. The correlate rate between HBDT and skin tests is 81,5%. This test's technical simplicity allows it's routine use by a non specialized laboratory.

[The treatment of hemoptysis by embolization of the systemic arteries (author's transl)].

The authors present their still limited experience of embolization of systemic arteries as the treatment of hemoptysis. Their cases illustrate the indications, contra-indications, causes of failure and effectiveness of this therapeutic method in pneumology. They had to refuse who patients: in the first, the pathological bronchial artery arose from a common trunk with the intercostal which gave rise to an anterior spinal artery. The second patient showed signs of medullary involvement on injection of a pathological right intercostal artery, which in their opinion is also a contra-indication of embolization, although no anterior spinal artery was demonstrated on the arteriogrammes. Six patients were treated by embolization. In the case of one patient, treatment was a failure owing to incomplete embolization. A main esophageal pedicle supplied a high flow bronchial artery anastomosis. These important collateral esophageal vessels compromize the effectiveness of bronchial embolization.
