MINERAL ELEMENTS IN CORPUS-LUTEUM OF BUFFALO

The changes in concentrations of copper, zinc, manganese, iron, magnes ium, sodium and potassium were measured in the corpus luteum (CL) of b uffalo during its formation, maturation and regression. Maximum concen trations of copper, zinc, iron, manganese and magnesium were observed in CL haemorrhagicum. Sodium and potassium showed a maxima in mature C L. The concentrations of mineral elements decreased significantly (P<0 .05) in regressing corpora lutea. The functional significance of these elements as related to luteal physiology has been discussed.
