We investigated the effect of swimming training in rats on morphological characteristics, hypertrophy levels and metabolic and contractile adaptations of different fiber types in rat the rectus abdominis muscle. Rats were randoverly assigned to one of three groups (N = 5 each): a) swimming training for 1 h, twice a week (2x/w), b) 1 h five times a week (5x/w) for 9 consecutive weeks, or c) without any swimming training (Control). Body weight increased in 2x/w rats and decreased in the 5x/w ones. Muscle fiber diameters increased in both trained groups, with higher values in the 2x/w group. Aerobic exercise increased slow oxidative (SO) + fast-oxidative-glycolytic (FOG) fibers and decreased fast glycolytic (FG) fibers. In addition, SO fibers were increased... |

Aspartame is a synthetic sweetener consumed by more than half the adult population in 75 countries. Their metabolites can be toxic, principally to the liver and retina, and there are few studies on the use of aspartame in gestation. Twenty pregnant rats were weighed and allocated randomly (n=5 per group) to receive 14 mg/kg aspartame or water by oral-gastric drip. Treated Tl: aspartame diluted in water at room temperature; Treated T2: aspartame diluted in water heated to 40° C; control Cl: water at room temperature; and control C2: water heated to 40° C. Placentas were weighed, umbilical cords measured and 1000 nuclei of fetal hepatocytes (250 from each group) were analyzed morphometrically utilizing the technique of kariometry, with application of the... |

To evaluate the effects of sodium cyclamate on the rat placenta by its administration in the period of embryogenesis. The sodium cyclamate was administered by intraperitoneal route in rats of the treated group at the dose of 60 mg/Kg, from the tenth to fourteenth day of gestation, while the equivalent volume of saline solution was given to the control group, by the same route. On the twentieth day of pregnancy, 10 fetuses (5 from each group) were chosen at random for study. The technique of cariometry was utilized for evaluation of nuclear parameters of cells in deciduous and spongy layers, and of chorionic villi in the rat placenta. The weights of treated fetuses and their placentas were less than those of the control group, while umbilical-cord length in... |

Sucralose is a sweetener of general use in over three thousand products (beverages, foods and medical diets), with utilization currently permitted for the general population in more than 80 countries, including for women of reproductive age. There is little information on the safe use of sucralose, and experimental studies have suggested that the administration of some sweeteners, by diverse routes, retards not only fetal and placental development but also umbilical cord size. The present study aimed to estimate the fetal and placental weights and umbilical-cord length in fetuses from rat dams, after ingestion and non-ingestion of sucralose. In the treated group (5 dams), sucralose was administered (via gavage) at the dose of 30 mg/kg/day, from the 10th to... |

Phenytoin (diphenylhydantoin, dilantin) has been the chosen anti-convulsive for the treatment of sudden disorders since the late 1930's. Several epidemiological and clinical studies in human beings showed an increase in malformations in descendants of which mothers took phenytoin during gestation, such as cranio-facial development and growth abnormalities, distal phalangeal hypoplasia, and light or moderate mental deficiency. This work had the goal to study the lingual mucosa, under histopathological and morphometric standpoints, in rat fetuses which were given an intraperitonial injection, consisting of a unique dose of phenytoin (70 milligrams/kilogram of their weight). Being that, we included the examined material in paraffin, 6 micrometers thick, and... |

Sucralose is a non-nutritive artificial sweetener, 600 times sweeter than sucrose, and is very stable at high temperatures, among other characteristics. It was approved by the FDA, in 1999, to be utilized in foods, beverages, pharmaceutical products, diets and vitamin supplements. Studies suggest a diffusion, through the placental barrier, of small doses of sucralose and its metabolites. Its hydrolysis products (4-CG e 1,6-DCF) are more rapidly absorbed than sucralose: 4-CG is excreted intact in the urine, and 1,6-DCF undergoes reduction with elimination by the urine or rapid conjugation with glutathione. Various organs can be affected by ingestión of high doses of sucralose. As a result of the rise in global consumption of sweeteners and light- or... |
