초록
Corallina pilulifera (CP) is prevalent along the Korean coastline and belongs to the Corallinaceae family, exhibiting growth throughout all seasons. This study confirmed the role of calcium supplementation through CP, calcined CP (CCP), and a commercial calcium powder, highlighting variations in dosage within animal models induced by a calcium-deficient diet. Analysis of calcium absorption was conducted by assessing the serum and urine calcium levels during the feeding periods. Serum calcium content was significantly higher in the control group (CON, 9.79 mg/dL) than in the calcium-deficient model (CDM, 6.15 mg/dL). The calcium content of urine was significantly higher than that of CON (0.20 mg/dL) compared with CDM (0.08 mg/dL). Reticular bone thickness showed no significant differences between the CON and CDM groups. Additionally, micro-CT results demonstrated a reduction in the trabecular volume and a significant difference between the number of strands and the average interval of the reticular bone. In conclusion, CP serves as a promising source of calcium supplementation. Therefore, these findings emphasize that CP is of sufficient value as an industrial material related to calcium metabolism.
