[Study on cellular and serum concentration of calcium and magnesium in peripheral blood cells of cirrhosis].
OBJECTIVE
To study on the changes of intracellular calcium and magnesium in cirrhosis and its clinical significance.


METHODS
The calcium and magnesium were determined in serum (SCa, SMg), platelets (PCa, PMg), mononuclear cells (MNCCa, MNCMg), polymorphonuclear cells (PMNCa, PMNMg) and erythrocytes (RCa, RMg) of 50 patients with uncompensative cirrhosis (group A) and of 35 patients with compensative cirrhosis (group B). 35 health persons were the control group.


RESULTS
The SCa and SMg of group A were lower significantly than those of both group B and control group. The MNCCa, PMNCa, RCa, PMg, MNCMg, PMNMg, RMg of group A [(4.76+/-1.91) micromol/10(9), (7.56+/-2.88) micromol/10(9), (0.66+/-0.13) mmol/L, (5.53+/-2.25) micromol/10(11), (6.64+/-3.53) micromol/10(9), (10.12+/-4.32) micromol/10(9), (2.02+/-0.76) mmol/L] and those of group B [(5.34+/-2.41) micromol/10(9), (8.32+/-2.34) micromol/10(9), (0.67+/-0.11) mmol/L, (5.55+/-2.67) micromol/10(11), (6.56+/-3.44) micromol/10(9), (10.95+/-4.45) micromol/10(9), (2.21+/-0.74) mmol/L] were lower significantly than those of control group [(6.86+/-2.02) micromol/10(9), (9.89+/-3.23) micromol/10(9), (0.72+/-0.10) mmol/L, (7.43+/-2.78) micromol/10(11), (8.68+/-4.1) micromol/10(9), (13.96+/-5.76) micromol/10(9), (2.74+/-0.92) mmol/L]; t (group A vs. control group)=4.88, 3.48, 2.31, 3.45, 2.46, 3.52, 4.00, 0.01, 0.01, 0.05, 0.01, 0.02, 0.01, 0.01; t (group B vs. control group)=2.87, 2.34, 2.00, 2.89, 2.33, 2.45, 2.65, 0.01, 0.05, 0.05, 0.01, 0.05, 0.02, 0.02. The PCa of the patients with hepatic encephalopathy was higher, the SMg, PMg, MNCMg, PMNMg and RMg were lower than those of the patients without hepatic encephalopathy significantly. The SCa, SMg, PMg, MNCMg, PMNMg and RMg of the patients in Child stage C were lower significantly than those of the patients in Child stage B. There were no significant differences of PCa, MNCCa, PMNCa and RCa between Child stage C and Child stage B. There were no significant differences of SCa, MNCCa, PMNCa and RCa between the patients with and without hepatic encephalopathy. The ratios of PCa/SCa, MNCCa/SCa and PMNCa/SCa of the patients with decreased SMg were lower than those of control group. The SMg, MNCMg, PMNMg and RMg were correlated directly with the level of serum albumin.


CONCLUSIONS
There are calcium and magnesium deficiencies in the patients with uncompensative cirrhosis and compensative cirrhosis, this deficiency aggravates with the severity of the disease. There is relative increase of intracellular calcium. The magnesium deficiency may be one of the reasons for both hepatic encephalopathy and relative increase of intracellular calcium.
