TAILIEUCHUNG - Effects of long-term exposure of female rats to low levels of lead: ovary and uterus histological architecture changes

The aim of the current study was to evaluate lead accumulation in the ovaries, fallopian tubes, and uterus and to take note of any consequent histo-architectural changes. The experiment involved a 12-month chronic exposure of 28 Wistar female rats at sexual maturity (221 ± g/individual) to lead acetate in drinking water. | Turkish Journal of Biology Turk J Biol (2015) 39: 284-289 © TÜBİTAK doi: Research Article Effects of long-term exposure of female rats to low levels of lead: ovary and uterus histological architecture changes 1 2 3 4 5 1 Eugenia DUMITRESCU , Viorica CHIURCIU , Florin MUSELIN , Roxana POPESCU , Diana BREZOVAN , Romeo T.

The experiment involved a 12-month chronic exposure of 28 Wistar female rats at sexual maturity (221 ± g/individual) to lead acetate in drinking water. The rats were divided into 4 groups based on the level of lead exposure: E1 at mg L–1, E2 at mg L–1, E3 at mg L–1 , and a control group that received tap water. Lead level evaluation was performed by atomic absorption spectrometry at nm and the histo-architectonics in target organs were evaluated after hematoxylin and eosin staining and microscopy. The exposure to lead acetate produced significant histological alterations
