摘要:

Treatment ofE. coliK12 AB1157 with a low concentration of toluene (10 μM) in buffer for as short an interval as ten minutes induced a large shoulder in the X-ray survival curve. This effect was independent of the presence of oxygen at the time of irradiation. A small decrease in the final exponential slope of the survival curve was also observed, which is attributed to chemical protection effected by a small amount of toluene remaining after removal of the bulk of the chemical before irradiation. Although the mechanism of the effect is at present unknown, the alteration in the shape of the X-ray survival curve from exponential to sigmoid suggests that changes in the cell membranes to a more fluid configuration may occur.

摘要:

The sighs of relief given out by the Treasurers of our Health Districts were almost audible after the first wave of enthusiasm following the introduction of fibre optic gastro-intestinal endoscopy had passed. The technique is now well established in most large hospitals in the UK, even though the exact role of these procedures in some clinical situations has yet to be established. But gastrointestinal endoscopy should not be treated as a subspecialty in its own right, but rather as one other technique which is available to help in the management of various gastrointestinal problems.

摘要:

The value of mammography in symptomatic patients is now well established, but its use as a mass screening technique for asymptomatic women is still controversial.In the fourth chapter of this report, the National Committee on Radiation Protection and Measurements of the USA tries to provide a considered view on relative risks and benefits of mammography. An earlier chapter also contains some very useful descriptions of equipment and techniques and the measurements that should be performed to ensure that equipment is operating satisfactorily.
