Change of calcimn metabolism in liver mitochondria and its effect on mitochondrial respiratory function fol- lowing biliary obstruction / 中华肝胆外科杂志

ABSTRACT

Objective To explore the change of liver mitochondrial calcium metabolism and its effect on mitochondrial respiratory function.Methods The model of dog biliary obstruction was made by bile duct ligation. Mitochondria were obtained by differential centfifugation.Mitochondrial calcium content,calcium uptake rate and respiratory function were observed and compared.Results Liver mitochondrial calcium content was increased sig- nificantly,calcium uptake rate and respiratory function were obviously reduced after biliary obstruction.Mitochon- drial calcium content was highly negatively correlated with mitochondrial respiratory function (P
