title: Effect of exogenous calcium deficit on blood pressure and modification of brain proteins GAP-43 and BASP1 in SHR and WKY rats.
abstract: We studied the effect of drinking of low mineralized water containing 8 mg/liter Ca2+ on blood pressure and content of brain proteins in synaptosomes of SHR and WKY rats. Blood pressure increased in WKY rats, but not in SHR rats. In SHR rats, Ca2+ deficit reduced the content of GAP-43 protein and induced the appearance of its fragment GAP-43-3 in brain synaptosomes. In WKY rats, the content of this protein did not change, and its fragment GAP-43-3 was absent. No structural changes in BASP1 protein were found.
