Osteoporosis becomes a serious health threat for older postmenopausal women by predisposing them to an increased risk of fracture. Osteoporosis and associated fractures are an important cause of morbidity and mortality. Special attention is being paid to early detection, management, and treatment of postmenopausal osteoporosis in women. Biochemical markers can enable dynamic and rapid measurement of total body skeletal metabolism and will be clinically useful in the management of postmenopausal osteoporosis women (PMO) and also for assessing the effects of antiresorptive therapy. With this view, we planned to assess osteoclastic activity by determining urinary hydroxyproline in osteoporotic women. The aim of this study is to measure urinary hydroxyproline (expressed as mg of hydroxyproline/g of creatinine) and serum ascorbic acid in postmenopausal women with osteoporosis and without osteoporosis. These biochemical parameters were determined 3 months post antiresorptive therapy (alendronate ? calcium ? vitamin D) in postmenopausal osteoporosis patients. 60 postmenopausal women with osteoporosis in the age group 45-60 years and 60 healthy postmenopausal women (normal bone mineral density) in the same age group were included in the study. Urinary hydroxyproline levels were significantly increased (P \ 0.001) in PMO at baseline level as compared to control group. These levels were decreased significantly (P \ 0.001) post therapy in PMO patients. Serum vitamin C levels were significantly decreased (P \ 0.001) in PMO patients at baseline level as compared to controls. No significant change occurred of serum vitamin C level post therapy. Raised excretion of hydroxyproline at the baseline level might be due to increased degradation of collagen type I from the bone matrix in osteoporosis. Breakdown of collagen seems to be lowered as reflected by lowering of hydroxyproline excretion post antiresorptive therapy. Alteration in the concentration of this marker can be very well utilized to monitor the effectiveness of therapy. Thus simple, direct urinary assay to measure bone resorption is very useful in monitoring the therapy in PMO and may become an integral part of the management of osteoporosis.
Thermal injury is associated with biochemical changes. The present study was undertaken to investigate relation of oxidative free radical generation and related biochemical parameters in burn trauma. The specific aim was to compare the levels of serum lipid peroxide, Ceruloplasmin and Uric Acid in burn patients during treatment with Silver Sulfadiazine Cream and honey therapy. It is a single blind prospective controlled study involving comparison of biochemical changes after treatment with silver sulfadiazine and honey treatment in burn injury. In burn trauma, there is excessive activity of free radicals at the site of injury. This is reflected in elevated blood levels of Lipid peroxide, Ceruloplasmin & Uric Acid. Honey therapy was was shown to decline the levels of serum Lipid peroxide, while there was mild increments in serum Ceruloplasmin levels whereas there was no significant effect on serum Uric Acid levels as compared to silver sulfadiazine treatment. Honey therapy seems to accelerate the process of healing. It has positive effect in reducing oxidative stressful state in burn trauma than the silver sulfadiazine treatment that results in rapid wound healing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
