Vitrous humour magnesium in sea and river water drowning an experimental study

Vitreous humor magnesium was estimated in two equal groups and a control groupof albino rats. Each test group [N-80] was divided into 8 equal subgroupswhich were drowned [first group in seawater, second group in river water] andremained immersed for 6, 12, 18, 24, 48, 72, 96 and 120 hours, respectively. Magnesium was estimated by atomic absorption spectrophotometer after aciddigestion of the vitreous. Significant increase of the vitreous magnesium wasfound in seawater drowning and immersion till the 24th hour after which thechanges became insignificant. In river water drowning, there wasinsignificant decrease with no correlation to immersion interval
