Effect of alloxan on calcium metabolism in mice and rats

Effect of AMP on serum minerals in carbon-tetrachloride hepatotoxicity

Carbon tetrachloride twenty-four hours after its administration resulted in a significant increase in serum iron, copper, zinc, calcium, potassium and sodium, while for magnesium no significant change was observed. A portion of this rise was due to the known hepatotoxic effect of CCl4 on the liver. Pretreatment with adenosine-5-monophosphate led to a normalization of the level of serum iron, copper and zinc, while in case of calcium, magnesium, potassium and sodium there was no significant change from that found in CCl4. The normalization of serum copper and iron under the influence of AMP may be due to some protective action of AMP on the liver. However, the disturbance in minerals metabolism may be considered as one of the earliest lesions in CCl4 poisoning.

Serum mineral changes in alloxan diabetes before and after treatment with some hypoglycemic drugs

In alloxan diabetes, serum zinc, copper, iron and magnesium were significantly higher than in normal rats, while the level of serum calcium, sodium, and potassium was lower than normal. Treatment with daonil or insulin led to a normalization, as expected of the level of serum glucose and most of the other elements, except for iron and potassium. When lycanol was used for treatment, the level of all elements returned to the normal except for blood glucose, zinc and potassium.
