Characterization of vitamin D-deficient klotho(-/-) mice: do increased levels of serum 1,25(OH)2D3 cause disturbed calcium and phosphate homeostasis in klotho(-/-) mice?
Klotho(-/-)/Cyp27b1(-/-) mice resemble Cyp27b1(-/-) mice. Since 1,25(OH)(2)D(3) is absent in these mice, our results imply that Ca(2+) homeostasis in klotho(-/-) mice is affected by their excessive 1,25(OH)(2)D(3) levels.
Neurosurgical operation may disrupt the integrality of BBB so that vancomycin can penetrate through the BBB easily and reach therapeutic concentration of CSF when administered intravenously after operation. This finding suggests that vancomycin can be administered intravenously when used to treat intracranial infection after neurosugical operation.
