Effect of cyanamide on transaminases and other serum proteins in the rat.

| Abstract |
The changes of the serum biochemical features induced by cyanamide, a drug used in the pharmacological treatment of alcoholism, were studied in Wistar rats. Sixty five Wistar rats were divided into 6 groups, 4 experimental and 2 control. Two experimental groups received cyanamide intraperitoneally, at a dose of 1 and 16 mg per kg of body weight, for 8 weeks. One experimental group received CCl4 and the other one CCl4 and cyanamide for 13 weeks. In addition to a delay in the increase of body weight as compared with the control group, the rats receiving cyanamide underwent a marked dispersion of the transaminase and LDH values. This could be explained by the double effect of cyanamide: its capacity to depress the cellular activity (lowered synthesis of proteins, transaminase and LDH among them) and cellular damage. Therefore, some animals showed a marked depression of protein synthesis, causing low enzyme values while cytolysis prevailed in the rest as seen in higher enzyme values. When cyanamide and CCl4 were employed simultaneously, the cyanamide tended to diminish the higher enzyme values caused by CCl4 when used alone. These findings can explain why patients on cyanamide may develop severe liver damage without serious alterations in tests for liver function.
