dc.description.abstract |
Phthalate esters, such as di(n-butyl) phthalate, (DBP), are synthetic chemical pollutants commonly used as plasticizers
in the manufacture of plastics. In the present study, we investigated the effects of DBP in the testes of adult male quails
(Coturnix cortunix japonica) exposed by oral gavage to variable doses of DBP (0 [control], 1, 10, 50, 200, and 400 mg/
kgbw−d), for 30 days during the prepubertal period, using histo-morphometric and ultrastructural techniques. Generally,
significant decreases in seminiferous tubular diameter (STD) and epithelial height (SEH) were observed predominantly at
the highest DBP doses (200 and 400 mg/kg), as compared to medium (50 mg/kg), and lowest doses (1 and 10 mg/kg) as
well as the control group. Ultrastructurally, apparent dose-specific degenerative changes were observed in the Leydig cells.
The lowest DBP doses (1 and 10 mg/kg) did not produce significant effects on Leydig cell ultrastructure, whereas, at the
highest doses (200 and 400 mg/kg), the Leydig cells were remarkably conspicuous in the interstitium and appeared foamy.
There was a preponderance of electron-lucent lipid droplets which crowded out the normal organelles of the cell, as well
as increases in the number of dense bodies in the cytoplasm. The smooth endoplasmic reticulum (sER) was less obvious,
compacted, and wedged between the abundant lipid droplets and mitochondria. Taken together, these findings indicate that
pre-pubertal exposure of precocious quail birds to DBP, produced parameter-specific histometric tubular changes, as well as
dose-dependent cyto-structural derangement of the Leydig cells; which consequently may lead to overt reproductive impairments
in the adult bird in the environment. |
