Morphological, biochemical and histological effects of aqueous extracts of peanut (Arachis hypogaea) on swiss mice in different diets.

Purpose: To evaluate the morphological, biochemical, and histological effects of aqueous extracts of peanut (skinless and added to 1% skin) in Swiss mice submitted to a high-fat diet.

Methods: Forty male Swiss mice were divided into four groups (n=10 per group): GI) normocaloric diet; GII) high-fat diet; GIII) high-fat diet + 0.5 mL of peanut extract; GIV) high-fat diet + 0.

Human bronchial epithelial cells injury and cytokine production induced by Tityus serrulatus scorpion venom: An in vitro study.

Tityus serrulatus is the scorpion specie responsible for the majority of scorpion sting accidents in Brazil. Symptoms of envenomation by Tityus serrulatus range from local pain to severe systemic reactions such as cardiac dysfunction and pulmonary edema. Thus, this study has evaluated the participation of bronchial epithelial cells in the pulmonary effects of Tityus serrulatus scorpion venom (Tsv).

Morphofunctional alterations of the nonpregnant murine uterus in response to intense and exhaustive exercise are not related to oxidative stress.

Exercise is a common and noninvasive way to improve human health. In contrast, intense exercise causes damage in various tissues and is usually associated with metabolic changes in organs and tissues. Even though intense exercise is associated with dysfunctions in the female reproductive system, much less is known about the cellular mechanisms underlying its effects particularly on the nonpregnant uterus.

Spasmolytic action of the methanol extract and isojuripidine from Solanum asterophorum Mart. (Solanaceae) leaves in guinea-pig ileum.

Solanum asterophorum Mart. (Solanaceae) is a shrub popularly known as "jurubeba-defogo" in the northeast of Brazil. In the present work, the methanol extract (SA-MeOH, 3750 microg/mL) and isojuripidine (10(-7) - 3 x 10(-4) M), a steroidal alkaloid obtained from S.
