OBJECTIVE To evaluate the hazardous effects of fried potato chips upon the retina of two developmental stages of the albino rats aged 7 and 14 days from parturition. METHODS PREGNANT RATS WERE ARRANGED INTO TWO GROUPS: control pregnant rats and consequently their delivered newborns until reaching 7 and 14 days old from parturition and fried potato chips group in which pregnant rats at the 6th...
Transcription activator-like effector nucleases (TALENs) are valuable tools for precise genome engineering of laboratory animals. Here we utilized this technique for efficient site-specific gene modification to create a fumarate hydratase (FH) gene knockout rat model, in which there was an 11 base-pair deletion in the first exon of the FH gene in 111 rats. 18 live-born targeted mutation offspri...
Introduction: Stress has many effects on the development of systems and organs in the fetal period, and these effects appear after birth. Since hemopoietic system is susceptible to stress, effects of restraint stress were studied in offspring of pregnant rats. Methods: Pregnant rats were divided into one control and three stress groups. The control group did not receive any stress during the ge...
We have investigated whether fetal exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) causes defects in the male reproductive system of the rat using chronically exposed rats to ensure continuous exposure of the fetus. Five- to six-week-old rats were exposed to control diet, or diet containing TCDD, to attain an average dose of 2.4, 8, and 46 ng TCDD/kg/day for 12 weeks, whereupon the rats ...
Poor development and differentiation of three layered cytoarchitectural pattern of brain, degenerating pyramidal cells with pyknotic nuclei and substantial loss of both large and small pyramidal cells of the hippocampal CA1 region were observed in fetuses of pregnant Charles-Foster rats exposed to single high dose of haloperidol (50 mg/kg body weight) on day 12 of gestation. In treated striatum...
Background and Objectives: Maternal prenatal stress while increasing the glucocorticoid level in the embryo, has detrimenal effects on the neural structure. This study examined the effect of maternal stress on the change of the frontal lobe in mice during pregnancy and also the seizure threshold in their offsprings. Materials and Methods: In this experimental study, 30 pregnant female mi...
Objective(s): Smoking opium/cigarette is a global health concern. The aim of this study was to examine learning and memory of rat male offsprings whose mothers had been exposed to either opium or morphine with nicotine during pregnancy. Materials and Methods: Wistar rats were used for the experiments. In the female rats, opium, morphine and nicotine dependencies were induced by daily injection...
BACKGROUND Dipteryx alata Vogel popularly known as "baru" is an important commercial leguminous tree species from the Brazilian Cerrado, which possess medicinal properties, besides its fruits consumption by animals and humans. The use of the "naturally occurring plants" as herbal remedies and foods mainly from leaves, seeds, flowers and roots of plants or extracts require precautions before ens...
The question was addressed of how nitric oxide synthase (NO synthase) inhibition-induced hypertension in rat parents would affect the cardiovascular system in their offsprings. Two experimental groups were set up: Group I -- offsprings of parents who had both been administered NO synthase inhibitor L-nitro-arginine methyl ester (L-NAME 40 mg/kg/day) for 5 weeks, the treatment of dams continued ...
