Perspectives on the nursing management of osteoarthritis.

Osteoarthritis is a daily presence in the lives of almost 16 million older people. Without expert nursing care, functional health status and the ability to manage independently may be dramatically altered. Nursing parameters include pain control, medication assessment, use of exercise, diet, joint protection, and attention to the psychosocial factors that affect both pain and disability.

Composition of lipids bound to pure cytochrome P-450 of cholesterol side-chain cleavage enzyme from bovine adrenocortical mitochondria.

Phospholipids bound to highly purified cytochrome P-450 from bovine adrenocortical mitochondria, part of the enzyme complex responsible for catalyzing the conversion of cholesterol to pregnenolone, have been examined for comparison with the bulk phospholipids of the mitochondria from the same tissue. In both cases, the major phospholipids are phosphatidylcholine (PC) (37%) and phosphatidylethanolamine (PE) (56%), as well as smaller amounts of sphingomyelin and diphosphatidylglycerol. The fatty acid compositions of the four classes of phospholipids and of the neutral lipids bound to the pure enzyme are indistinguishable from those of the respective mitochondrial lipids.
