Variable response to long-term 1alpha-hydroxycholecalciferol in haemodialysis osteodystrophy.

Ten uraemic patients on regular haemodialysis were treated with 1alpha-hydroxycholecalciferol (1alpha-H.C.C.

Post-natal developmental changes in the length-tension relationship of cat papillary muscles.

The length-tension relationship and the effect of paired electrical stimulation were studied in right ventricular papillary muscles obtained from cats. The animals were divided into three age groups: neonatal kittens, less than 24 hr of age; infant kittens, 16--18 days of age; and adult cats. 2.

An oxygen enrichment attachment for use with humidified air.

, , 371-376. An oxygen enrichment attachment is described which fulfils the basic requirements for intubated patients. Using values for tidal volume and inspiratory time found in the type of patients for whom the attachment is intended, a range of mean inspired oxygen concentration has been given for 2, 4, 6, 8, and 10 1/min oxygen flow.
