Pus, deoxyribonucleic acid, and sputum viscosity.
On 100 sputum specimens selected from patients suffering from chronic bronchitis, bronchiectasis, asthma, and cystic fibrosis total deoxyribonucleic acid (DNA) content has been related to macroscopic type, to total dry weight yield, and to the apparent viscosity of the secretion at 1350 s-1: since DNA may be present, either as fibres or within cells, in one-third of the specimens the contribut...
متن کاملSputum viscosity and postoperative pulmonary atelectasis.
The relationship between changes in the viscosity of sputum and the development of pulmonary atelectasis has been discussed.15 The fibers found in sputum which appear to be responsible for the viscosity are
متن کاملdeoxyribonucleic acid
Triostin antibiotics, which contain a cyclic peptide with a disulphide bridge, have been prepared by growing Streptomyces triostinicus in the presence of inorganic [3PS]sulphate. The labelled triostin A has been shown to behave in all respects similarly to the authentic natural product and to enable a much more sensitive radiochemical adaptation of the solvent-partition method for determining a...

The effects of the three antibiotics U-12,241, nogalamycin, and U-20,661 on (i) deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) synthesis in KB cell cultures and cell-free systems of bacterial and mammalian origin and on (ii) oxidative phosphorylation in rat liver mitochondria were compared. Nogalamycin and U-12,241 inhibited RNA synthesis more strongly than DNA synthesis in all test sys...
متن کاملDeoxyribonucleic acid-deoxyribonucleic acid hybridization assay for replication origin deoxyribonucleic acid of Escherichia coli.
Deoxyribonucleic acid (DNA)-DNA hybridization on nitrocellulose filters can be used to assay for replication origin DNA from Escherichia coli if the DNA attached to the filters is enriched for the replication origin sequences. Such DNA can be readily isolated from very rapidly growing cells. When low amounts of this DNA were attached to filters, radioactively labeled DNA from the replication or...
