Hydroxyproline peptides and bone mass in postmenopausal and osteoporotic women. 1978

J F Aloia, and S H Cohn, and I Zanzi, and C Abesamis, and K Ellis

Total and nondialyzable hydroxyproline excretion was measured in 59 postmenopausal women and 68 women with spinal osteoporosis. Hydroxyproline excretion was similar in both groups of women and the hypothesis that hydroxyproline excretion is normally distributed could not be rejected for either group. No relationship was found between hydroxyproline excretion (total and percentage of nondialyzable) and body weight, height, body surface area, or total body calcium or bone mineral content of the radius, or these latter values normalized for age, sex, and body size. There was no difference in hydroxyproline excretion in osteoporotic women who took supplemental calcium as compared to those that did not. These data fail to provide any evidence that bone turnover in osteoporotic women differs from that in younger postmenopausal women, or that osteoporosis arises from a subpopulation of women with rapid bone loss.

UI MeSH Term Description Entries
D008593 Menopause The last menstrual period. Permanent cessation of menses (MENSTRUATION) is usually defined after 6 to 12 months of AMENORRHEA in a woman over 45 years of age. In the United States, menopause generally occurs in women between 48 and 55 years of age. Change of Life, Female
D010024 Osteoporosis Reduction of bone mass without alteration in the composition of bone, leading to fractures. Primary osteoporosis can be of two major types: postmenopausal osteoporosis (OSTEOPOROSIS, POSTMENOPAUSAL) and age-related or senile osteoporosis.

D010455 Peptides Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS. Peptide,Polypeptide,Polypeptides
D011392 Proline A non-essential amino acid that is synthesized from GLUTAMIC ACID. It is an essential component of COLLAGEN and is important for proper functioning of joints and tendons. L-Proline,L Proline

D001842 Bone and Bones A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principal cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.
