5.Effectiveness of mineralized gelatin electrostatic spinning on inducing periodontal tissue osteogenesis
Chinese Journal of Tissue Engineering Research 2015;(47):7583-7588
BACKGROUND:Currently, little is reported regarding the effectiveness of mineralized gelatin electrostatic spinning fibers on periodontal tissue osteogenic induction. OBJECTIVE: To investigate the effect of mineralized gelatin electrostatic spinning on the proliferation and osteogenic differentiation of periodontal ligament fibroblasts. METHODS: Human periodontal ligament fibroblasts were respectively compositely cultured with non-mineralized gelatin electrostatic spinning, gelatin electrostatic spinning after 1 day of nano-hydroxyapatite mineralization and gelatin electrostatic spinning after 5 days of nano-hydroxyapatite mineralization. Cel proliferation was determined at 1, 4, 7, 10 and 13 days of culture using MTT assay. Alkaline phosphatase activity of cels was determined at 1, 7, 14 days of culture using biochemical analyzer. RESULTS AND CONCLUSION:At the 10th day of culture, the periodontal ligament cels on the surface of membrane distributed uniformly, grew wel, spread out as sheets and secreted a large amount of extracelular matrix, linked closely with the materialsl; moreover, the effect was more obvious at 5 days of mineralization. Cel growth density and status were better than those in the non-mineralized gelatin electrostatic spinning membrane group. Cel proliferation and alkaline phosphatase activities at different time points: 5-day mineralized gelatin electrostatic spinning membrane group > 1-day mineralized gelatin electrostatic spinning membrane group > non-mineralized gelatin electrostatic spinning fibers group (alP < 0.05). These results demonstrate that the gelatin electrostatic spinning after nano-hydroxyapatite mineralization may promote the proliferation and osteogenic differentiation of periodontal ligament fibroblasts in a time-dependent manner.
6.Advances in Effects of Cadmium on Calcium Metabolism and Its Associated Potential Mechanisms
Journal of Environment and Health 1992;0(04):-
Cadmium targets on kidney and bone and results in many toxic effects. Disturbance of calcium metabolism is one of the important aspects of cadmium toxicity, which includes reduced intestinal calcium absorption, increased urinary calcium excretion, negative calcium balance, development of osteomalacia and osteoporosis. There exists two potential mechanism of influence of cadmium on calcium metabolism. One is the direct inhibition of cadmium on active transports of calcium. The other is the indirect influence on calcium metabolism due to reduced renal synthesis of 1,25-dihydroxycholesterol induced by cadmium. Further research should focus on revealing how cadmium directly inhibits calcium entering into cells and transporting by calcium binding protein, elucidating whether renal synthesis of 1,25-dihydroxycholesterol is reduced in low-level cadmium exposure population, and also on clarifying the molecular biological mechanism of effects of cadmium on calcium metabolism.
