Abstract:   (4816 Views)
To study the lead effect, we selected 14 females rats in which we had observed vaginal plague after mating, and divided them into a group of 8 female rats as the case group and 6 females as the control group. As drinking water the case group was given 0.13% lead acetate solution and the control group pure distilled water. Immediately after parturition the pups were killed and their livers removed. A small part of the liver was fixed in glutaraldehyde and osmium tetroxide in order to be studied with transmission electron microsope. The fixated parts were dehydrated and embed in Epon 812. using ultramicrotomoe, we prepared semithin seclions of the tissues, stained them with toludine blue, and studied them under light microscope. Further more we prepared thin sections of the tissue to be placed on grids coated with formvar. These sections were stained by uranyl acelate and lead citrate. Electron microscopic study was performed on them. Results: T.E.M. study showed the swelling and blebbing of nuclear envelop and endoplasmic reticulum and mithochondria of hepatocytes.
