    Abstract:
    Twenty-seven histopathologically proved cases of Indian childhood cirrhosis (ICC), 13 parents (father and mother) and nine siblings of ICC patients were studied from serum and urinary Cu, Zn, Mg and Cd levels by Atomic Absorption Spectrophotometer (AAS). Milk and drinking water from various sources were analysed for Cu, Zn, Mg and Cd contents, as was milk boiled and stored for up to six hours in various utensils. Serum and urinary Cu excretion were high (P less than 0.001) in ICC patients and within normal limits in siblings and parents. In ICC patients most hepatocytes contained multiple, coarse and dark brown orcein staining granules representing Cu associated protein. Serum Zn was low and urinary Zn excretion high in ICC patients (P less than 0.001 and P less than 0.01 respectively) and within normal limits in siblings and parents. Mg and Cd in serum and urine of ICC patients, siblings and parents were within normal limits. Cu content of milk boiled and stored in peetal (brass) utensils was high and directly related to the duration of storage; there was no change in Cu level in milk boiled and stored in steel and aluminium utensils. Zn, Mg and Cd levels in milk boiled and stored in peetal (brass) utensils remained unchanged. The levels of these elements in drinking water from various sources were also within limits as recommended by WHO (1971). Milk boiled and stored in peetal (brass) utensils seemed to account for increased Cu intake. Excessive Cu intake in ICC should be eliminated by avoiding brass utensils for boiling and storing milk. Some treatment to chelate excess Cu is also warranted.
