Bleomycin is a chemotherapeutic agent used in the treatment of different tumours. It has several side effects, including flagellate hyperpigmentation, which is a unique and a well-documented side effect of bleomycin therapy. We report a case of a 23-year-old woman with a personal history of ovarian dysgerminoma, who developed flagellate hyperpigmentation on trunk after bleomycin therapy.

BACKGROUND Despite its widespread use in pulmonary fibrosis research, the bleomycin mouse model has not been thoroughly validated from a pulmonary functional standpoint using new technologies. Purpose of this study was to systematically assess the functional alterations induced in murine lungs by fibrogenic agent bleomycin and to compare the forced oscillation technique with quasi-static pressu...

INTRODUCTION Supplemental oxygen has been reported to cause pulmonary complications after bleomycin. We describe the safe administration of hyperbaric oxygen (HBO2) after bleomycin in 15 patients. METHODS Paper and electronic records were reviewed for bleomycin-exposed patients at the Duke Center for Hyperbaric Medicine and Environmental Physiology from 1979 to 2010. RESULTS Fourteen bleomy...

Native chromosomal structure, breakage, and overall degradation were studied following the reaction of whole cells with the anticancer drug bleomycin and structurally related phleomycin. Electrophoretic analyses of cellular DNA established that phleomycin was more reactive with DNA than equimolar bleomycin in the range of 0.67-33 x 10(-6) M, produced an optimally visible, though less-extended, ...

Introduction: Bleomycin is a chemotherapeutic agent commonly used to treat curable diseases such as Hodgkin’s lymphoma. The major limitation of bleomycin therapy is the pulmonary toxicity. Pirfenidone is a modified phenyl pyridine that has an antioxidant, anti-transforming growth factor and anti-platelet derived growth factor effects. Aim of the study: to evaluate the histological, immunohistoc...

Preferential sensitivity of specific genes in chromatin to the action of bleomycin in different cell types was investigated using restriction enzyme digestion of DNA from drug-treated nuclei in combination with the Southern blotting procedure. The results show that the highly active ovalbumin gene in laying hen oviduct nuclei is more sensitive than the inactive globin gene to the digestion by b...

Pulmonary fibrosis is characterized by excessive deposition of extracellular matrix components in the alveolar space, which hampers normal respiration process. Pathophysiological enzymes, glycoprotein moieties and matrix degrading lysosomal hydrolases are key markers and play a crucial role in the progression of fibrosis. Bleomycin is an anti-neoplastic drug, used for the treatment of various t...

Oxidative stress is involved in the pathogenesis of pulmonary fibrosis, therefore antioxidants may be of therapeutic value. Clinical work indicates that N-acetylcysteine (NAC) may be beneficial in this disease. The activity of this antioxidant was examined on bleomycin-induced lung damage, mucus secretory cells hyperplasia and mucin Muc5ac gene expression in rats. NAC (3 mmol x kg(-1) x day(-1)...

BACKGROUND Pulmonary fibrosis is an untreatable, fatal disease characterized by excess deposition of extracellular matrix and inflammation. Although the etiology of pulmonary fibrosis is unknown, recent studies have implicated dysregulated immune responses and wound healing. Since n-3 polyunsaturated fatty acids (n-3 PUFAs) may beneficially modulate immune responses in a variety of inflammatory...
