چکیده
= Abstract = This experiment was performed through the rosette formation method to study the inhibition mechanism of the immune response in the spleen of young rats born to azathioprine-administered pregnant rats. The following results were obtained. 1. In the group I consisting of animals born to normal pregnant rats and immunized with sRBC after birth, there was increase in the number of RFC, compared with that in the group 0 consisting of animals born to normal pregnant rats and not immunized with sRBC. 2. In the group II consisting of animals born to azathioprine-administered pregnant rats and immunized with sRBC, there was decrease in the number of RFC, compared with that in the group I. However the group III, which consists of animals born to azathioprine-administered pregnant rats and inoculated with thymus cells derived from outbred animals and simultaneously immunized with sRBC, showed much more RFC than other groups. 3. Generally the 3rd day post sRBC injection groups showed more RFC than the 7th day post sRBC injection groups. 4. The number of RFC increased with age in the sRBC-injected groups. Above results suggested that peripheral T lymphocytes were depleted due to retarded fetal development of thymus caused by azathioprine.

Place Aversion by Morphine in Offspring Born of Female Morphine Administered Wistar Rats
This research was designed to study sexual differences in place conditioning induced by morphine in offspring born of female Wistar rats mated with drug-naïve males. Mothers were exposed to morphine during the 14th-16th days of gestational. Control dams were simply saline-injected. Female and male virgin offspring born of morphine-treated or saline-treated mothers were separately housed until b...

Enamel hypoplasia is an important clinical problem commonly seen in children born to diabetic women. We aimed to characterize the enamel hypoplasia in Wistar rats born to alloxan-induced diabetes mellitus rats. Groups consisted of pregnant rats supplemented (ISDR) or not (NISDR) with insulin and controls, in which sterile saline solution was administered instead of alloxan or insulin. The mandi...

During pregnancy, diabetes mellitus exerts detrimental effects on the development of the fetus, especially the central nervous system. In the current study, we evaluated the effects of postnatal treadmill exercise on short-term memory in relation with cell proliferation and apoptosis in the hippocampus of rat pups born to streptozotocin (STZ)-induced diabetic maternal rats. Adult female rats we...

Background: Paraquat (PQ), an herbicide, is a very poisonous compound for both humans and animals. This study was conducted to examine the protective effect of the Coenzyme Q10 (CoQ10) in newborn rats from pregnant rats pre-treated with PQ. Methods: The experiments were conducted on 25 rats, divided in five groups randomly and equally: 1 - Control Group received normal saline (0.1ml/day); 2...
