Objective :To establish a simple, reproducible brain edema model induced by endotoxin in infant rats and explore the role of intracellular free calcium and calmodulin (CaM). in the development of brain edema. Methods: A total of 45 infant rats were divided randomly into endotoxin treated( n = 36) and control( n = 9) group. The animals were intraperitoneally injected with 10mg/kg of endotoxin or saline respectively. The brain tissue intracelluar free [Ca2 + ] as well as the expression of CaM was detected by fluorescence and protein hybridizaton methods respectively. The tissue water content,Evans Blue content and pathology under electronic microscope were also observed. Results:Brain water and EB content were remarkably increased in endotoxin treated animals compared with those in the control, in which the intracellular free [Ca2+ ] was also significantly increased and the expression of CaM up - regulated. Electron microscopic studies revealed that the blood - brain barrier(BBB)was disrupted with neuronal degeneration,neurogliocyte swelling and necrosis. Conculsion :These results suggest that LPS increases the intracellular free [Ca2+ ] ,and activates the CaM - dependent function via Ca2+ /CaM pathway,which might relate to the increased BBB permeability and brain edema formation.

Strontium-89(89Sr)therapy has been recognized as an effective method for treating bone metastases. It functions as a calcium analog that binds with collagen matrix produced by the MC3T3-E1 cells during collagen mineralization. 89Sr emits pure β rays which palliate bone pains and reduce the number of new metastasis sites. Response to 89Sr is affected by factors such as the location, size and histological type of lung cancer, the type of metastasis and the duration of treatment, and can be predicted by relief of bone pain, elimination of metastasis, CD4 +/CD8 +, ALP, and others. 89Sr therapy is safe and effective. Repeat administration or combined used with other treatments can improve the therapeutic effect of 89Sr.
