The cortical matrix of femur in adult-aged Wistar rats is critically affected by maternal malnutrition during lactation period

Int. j. morphol; 36 (4), 2018
Osteoporosis is associated with poor dietary habits. Malnutrition is characterized as a deficit on the intake of necessary nutrients that are essential for optimal health maintenance. It is known that malnutrition during the lactation period can affect the offspring. The present study aims to evaluate th...

Adaptations of muscle tissue of rats submitted to aerobic and anaerobic physical training in different ergometer models

Int. j. morphol; 36 (4), 2018
SUMMARY The objective of the present study was to analyze the effects of four different training models, two aerobic and two anaerobic models, in relation to muscular hypertrophy, by means of morphometric analysis of the muscle cells of the soleus muscle and the extensor digitorum longus muscle (EDL). Th...

Effect of wheatgrass on DNA damage, oxidative stress index and histological findings in diabetic rats

Int. j. morphol; 36 (4), 2018
This study was aimed to search the effect of wheatgrass on the Total Antioxidan (TAS)-Oxidan Status (TOS) and DNA damage in rat with diabetes. The rats used in the study were randomly divided into 4 groups that each of has 10 rats: Control group; 1 ml single dose phosphate-citrate buffer injected i.p (pH...

Intermittent training followed by detraining provides the preservation of hepatic tissue and body composition of eutrophic rats in relation to obese rats after the detraining period

Int. j. morphol; 36 (4), 2018
The aim of the study was to evaluate the effects of intermittent training followed by detraining on liver tissue and body composition of rats subjected to a normolipidic or hyperlipidic diet. Sixty Wistar rats were divided into the groups Sedentary Control (SC), Exercised Control (EC), Sedentary Control ...

Alterations in morphology and aerobic resistance of rats subjected to different physical training protocols

Int. j. morphol; 36 (4), 2018
The objective of this study was to investigate the alterations in morphology and aerobic resistance of rats subjected to different physical training protocols. The study consisted of 55 rats of the "Wistar" breed, 100 days of age, over a period of 8 weeks. The animals were randomly distributed between fo...

Beneficial effects of Oltipraz, nuclear factor - erythroid - 2 - related factor 2 (Nrf2), on renal damage in unilateral ureteral obstruction rat model

Int. braz. j. urol; 44 (6), 2018
ABSTRACT Introduction: We investigated whether Oltipraz (OPZ) attenuated renal fibrosis in a unilateral ureteral obstruction (UUO) rat model. Materials and Methods: We randomly divided 32 rats into four groups, each consisting of eight animals as follows: Rats in group 1 underwent a sham operation and ...

Macroscopic and microscopic evaluation of flapless alveolar perforations on experimental tooth movement

Abstract Objective: The aim of this study was to evaluate a flapless surgical technique as an alternative to traditional alveolar corticotomy used to accelerate orthodontic tooth movement (OTM). Methods: To induce OTM in Wistar rats, 40 cN of orthodontic force were applied to the maxillary left first ...

Hypericum perforatum chronic treatment affects cognitive parameters and brain neurotrophic factor levels

Objective: To evaluate the effects of Hypericum perforatum (hypericum) on cognitive behavior and neurotrophic factor levels in the brain of male and female rats. Methods: Male and female Wistar rats were treated with hypericum or water during 28 days by gavage. The animals were then subjected to the ope...
