The bleomycin family of glycopeptide anti-tumour antibiotics has recently been shown to be markedly photosensitive. This photosensitivity has been observed not only for the free antibiotics but also for complexes with metal ions and with DNA. More importantly, the pattern of DNA cleavage by bleomycin, and some of its metal complexes, is significantly(More)
The immunogenicity and adverse effects of an acellular pertussis vaccine consisting of a purified pertussis toxin inactivated with hydrogen peroxide (PTxd) was evaluated. Children aged 15 to 30 months were injected with 10 (n = 33) or 50 micrograms (n = 34) of PTxd or with diphtheria and tetanus toxoids and whole cell pertussis vaccine (DTP) (n = 34). All(More)
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a chronic obstructive lung condition, diagnosed in patients with dyspnoea, chronic cough or sputum production and/or a history of risk factor exposure, if their postbronchodilator forced expiratory lung volume in 1 second (FEV1)/forced vital lung capacity (FVC) ratio is less than 0.70, according to(More)
Incubation of supercoiled plasmid DNA (both pBR 322 and pPLC-28) with increasing concentrations of bleomycin in the presence and absence of light (300-350 nm) showed extensive conversion of supercoiled to linear DNA which occurred at much lower levels of bleomycin (BLM) in the light than in the dark. Preliminary results indicate that superoxide dismutase(More)
