The aim of this work is to investigate the photoprotection activity and toxicity level of formulations containing the extract and its fractions obtained from leaves of Arrabidaea chica. The ex vivo percutaneous penetration of the extract was evaluated using the photoacoustic spectroscopy technique. The formulation presented optical absorption in the(More)
The aim of this work was to evaluate the effects of therapeutic doses of Cimicifuga racemosa on cardiovascular parameters and on liver lipid metabolism and redox status in an animal model of estrogen deficiency associated with hypertension, a condition that could make the liver more vulnerable to drug-induced injuries. Female Wistar rats were subjected to(More)
OBJECTIVES To evaluate the effects of dietary restriction on oxidative status, the HuC/D-neuronal nitric oxide synthase (nNOS) myenteric neuron population, HuC/D-S100 glial cells, and the morphometry of the small intestine in rats at various ages. METHODS Fifteen Wistar rats were divided into 7-and 12-mo-old control groups and a 12-mo-old experimental(More)
The effect of graded levels of dietary available phosphorus (AP) on large Nile tilapia (145.87 ± 9.51 g) performance, feed efficiency, body composition and mineral retention in vertebrae was evaluated. All male fish were distributed into three replicates in fiberglass aquaria (800 L each; 12 fish per tank) for 87 days and hand fed to pelletized diets three(More)
OBJECTIVE The effects of a cafeteria diet on the small intestine were investigated in adult Wistar rats under sedentary conditions and after physical training. METHODS Parameters including morphometry, enzyme activities, and total myenteric populations in the jejunum were evaluated. RESULTS The cafeteria diet, characterized as hyperlipidic, produced(More)
Anethole has been reported to have antioxidant, antibacterial, antifungal, antiinflammatory, and anesthetic properties. In the present study, we evaluated the effects of anethole in two pain models of inflammatory origin: acute inflammation induced by carrageenan and persistent inflammation induced by Complete Freund’s adjuvant. We evaluated the effects of(More)
Intestinal ischemia/reperfusion injury can be caused by surgical procedures and inflammatory bowel disease. It is normally associated with the increased production of free radicals and changes in the enteric nervous system. Given the antioxidant and neuroprotective properties of resveratrol, the present study assessed its influence on oxidative stress in(More)
Food restriction may slow the aging process by increasing the levels of antioxidant defenses and reducing cell death. We evaluated the effects of food restriction on oxidative and nutritional status, myenteric cell populations, and the colonic muscle layer in aging rats. Wistar rats were distributed into control groups (7, 12, and 23months of age) and(More)
BACKGROUND This study evaluated the performance, prevalence of ectoparasites and morpho-functional response of the liver and the branchiae of Nile tilapia (Oreochromis niloticus) raised on fish meal with added of the homeopathic complex Homeopatila 100(®) at different concentrations. METHODS Post-reversed juvenile Nile tilapia (O. niloticus) of the GIFT(More)
Vitex agnus-castus (VAC) is a plant that has recently been used to treat the symptoms of menopause, by its actions on the central nervous system. However, little is known about its actions on disturbances in lipid metabolism and nonalcoholic fat liver disease (NAFLD), frequently associated with menopause. Ovariectomized (OVX) rats exhibit increased(More)
