| The study aimed to verify the physiological injury behavior by stretching the soleus muscle of rats, using a noninvasive experimental model. Twenty-four rats were used and divided into three groups of eight animals: control group (A), group that performed tetanus followed by electrical stimulation and a sudden dorsiflexion of the left paw performed by a device equipped with a mechanism of muscle soleus rapid stretching (B); and a group that only received the tetanus (C). Three days later, the animals were killed, and the soleus muscle was resected and divided into three segments. Morphological changes indicative of muscle damage appeared in all three segments of group B. In a lesser degree, similar changes were also detected in muscles subjected to only... |

| The current study aimed to analyze the histochemical and morphological characteristics of the levator ani muscle in rats. For this, we used 10 Wistar rats (5 males and 5 females), weighing between 200 and 765g. The animals were dissected fresh and in formalin for the levator ani muscle anatomical observation. Muscle fragments were collected and frozen in n-Hexane previously cooled in liquid nitrogen. Then, the muscles were transferred to a microtome cryostat (HM 505 E Microm), being fixed in metal mounts with the adhesive Tissue Freezing Medium. Histological sections of 6.0µm were removed and subjected to HE staining. Other sections were subjected to NADH-TR and SDH reactions. After being dissected and fixed, the architecture of the female pelvic floor... |

| Physical effort stimulates an increase in oxygen consumption in tissues, generating toxic chemical species derived from oxygen (ROS), which are considered the initiators of the lipid peroxidation process (LPO), the major mechanism of cellular injury. As the essential mechanism for maintaining the electrolyte balance depends on an effective kidney function, oxidative stress in this organ can be a key factor in the development and persistence of hypertension. This study aimed to determine the kidney changes induced by a combination of fluid restriction and exercise in rats. The study consisted of 24 male Wistar rats of 90 days of age, divided into four groups, two of which were submitted to water restriction and exercise on a treadmill.Twenty-four hours... |
