The objective of the current study was to estimate the effect of vitamin C on BMD in menopausal women with balanced dietary. In the randomized controlled clinical trial, 150 menopausal women suffering from osteoporosis were chosen in purposive sampling method. In randomized block design, the individuals were placed in the received vitamin C (test) and placebo (control) groups. After integrating groups, the test group received 1000 mg of vitamin C in two divided doses for 6 months and the placebo control group received in the same method. There was a significant correlation between obstetric history with lumbar BMD (r= -295 and p<0.001) and femoral BMD (r= -0.226 and p=0.006). The average index changes of vertebral bone density did not indicate a statistically significant difference in the vitamin C group (0.02±0.05, P=0.001) and the placebo group (0.02±0.04, P<0.001) before and after treatment. With respect to the findings of the study about the effects of vitamin C on BMD, antioxidant is suggested to add to the current treatments.DOI: http://dx.doi.org/10.3126/ijls.v8i4.10930
The Alborz-Azerbaijan magmatic zone in northern Iran is one of the important zones of magmatic activity in the Cenozoic. Lithologically, this complex consists of olivine gabbro, monzogabbro, dolerite, and gabbro with granular, intergranular, and porphyritic textures. The main phenocrysts of these rocks are clinopyroxene, plagioclase, and sometimes iddingsitized olivine. The rocks producing magma has potassic and shoshonitic nature. Enrichment in large-ion lithophile elements (LILEs), i.e., Ba, Rb, and Th, and depletion of high-field strength elements (HFSEs), i.e., Ti and Nb, in the spider diagrams are of the characteristics of subduction and active continental margin rocks. Also, these diagrams show enrichment in the light rare earth elements (LREEs) compared to heavy rare earth elements (HREEs). This feature also is representative of the rocks of subduction zones and active continental margins. The geochemical and petrogenetic studies indicate unique origin of the intrusive rocks in the study area and the role of fractional crystallization with simultaneous crustal assimilation (AFC) and magma contamination with crustal rocks in the evolution of the magma forming these rocks. This magma is obtained from the low-degree partial melting of an enriched mantle source beneath the continental lithosphere with garnet lherzolite composition at a depth of 100 to 110 km in a post-collision extensional basin.
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.
