the aim of present study was to investigate the potential antioxidant and lung protective activities of sambucus ebulus (se) against toxicity induced by gamma irradiation. hydro alcoholic extract of se (20, 50 and 100 mg/kg ) was studied for its lung protective activity. . phenol and flavonoid contents of se were determined. male c57 mice were divided into 10 groups with five mice per group. on...

Ribs from 3 preterm infants, who had died after prolonged intravenous feeding and artificial ventilation, were examined histologically and assessed for the degree of osteomalacia and osteoporosis in cancellous bone of the shaft. A grid counting technique was used. Osteomalacia was noted in all 3 cases but to a lesser degree than in classical vitamin D-deficient controls. Osteoporosis was pronou...

Background: Adenocarcinoma of the lung, once considered minimally related to cigarette smoking, has become the most common type of lung cancer in the United States. The increased incidence of this cancer might be explained by advances in diagnostic technology (i.e., increased ability to perform biopsies on tumors in smaller, more distal airways), changes in cigarette design (e.g., the adoption ...

Giant cell arteritis (GCA) is a systemic granulomatous vasculitis of unknown aetiology, which typically affects the branches of carotid artery (especially the temporal artery), but it can involve any medium-size or large artery, and then its diagnostics becomes much more difficult. The aim of our study is to point up typical histopathological changes in the aorta of GCA patients. In the study w...
