Abstract
Blood samples were collected fr01ll50 women for the study of serum calcium.
magnesium. zinc. copper and manganese; before an injection of DMPA in a
dose of 150 118. and 48 hours. one week. 2 weeks. one month and 3 months after
injection. The ”atomic absorption spectrophotometery” method was used to
determine the serum minerals levels.
1- Serum calcium I
Mean serum calcium level showed a statistically significant decrease 48
hours after DMPA injection. Afterwards. one week and 2 weeks after injection.
mean serum calcium level was restored to its normal pre-injection level. One
month after injection. mean serum calcium level showed a significant increase.
Three months after injection. mean serum calcium level returned to preinjection
level again. With both the decrease and increase that occurred. the
range levels were within the normal range of serum calcium.
2- Serum magnesium I
There was no significant change in mean serum magnesium levels.
throughout the study period.
3- Serum zincI
Mean serum zinc levels showed a statistically significant decrease 48
hours. one week. 2 weeks. one month and 3 months after DMPA injection. Once
the decrease occurred 48 hours after the injection. no further decrease
resulted. However. with this decrease. range serum zinc level was within the
normal range of serum zinc.
4- Serum copper I
Mean serum copper levels showed no significant change at all after DMPA
injection. throughout the study period.
5- Serum manganese I
Mean serum manganese showed a statistically significant decrease 48
hours. one week and 2 weeks after DHPA injection. After that. mean level
returned to its pre-injection level and did not showany significant change
one monthand 3 months after injection. However. with the decrease. range
serummanganeselevel was within the normal range of serummanganese.
