The objective of this study was to analyze the morpho quantitative behaviour of duodenum myenteric neurons of Wistar rats (Rattus norvegicus), aged 21, 60, 90, 210, 345 and 428 days, using wholemount preparations of the muscular tunica obtained by dissecting the intestinal tunica for neuronal revealing, through the Giemsa non-histochemical and Myosin-V(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)
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)
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)
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)
The objective of this work was to analyze the morphoquantitative behavior of neurons of the myenteric plexus, as well as the morphometry of elements of the proximal colon wall of Wistar rats (Rattus norvegicus) fed a normoproteic (22%) and a hypoproteic (8%) diet, and sacrificed at 360 days of age. To perform the neuronal evaluation, we used whole-mount(More)
We evaluated the effects of the supplementation with L-glutamine and glutamine dipeptide (GDP) on biochemical and morphophysiological parameters in streptozotocin-diabetic rats. For this purpose, thirty animals were distributed into six groups treated orally (gavage) during thirty days: non diabetic rats (Control) + saline, diabetic + saline; Control +(More)
The action of an Agaricus blazei aqueous extract pretreatment on paracetamol injury in rats was examined not only in terms of the classical indicators (e.g., levels of hepatic enzymes in the plasma) but also in terms of functional and metabolic parameters (e.g., gluconeogenesis). Considering solely the classical indicators for tissue damage, the results can(More)
This study focused on the therapeutic effect of a propolis SLNC 106 (PI) extract on experimental colitis. Wistar adult rats received 0.8 mL rectal dose of one of the following solutions: saline (group S), 20 mg TNBS in 50% ethanol (group TNBS), 20 mg TNBS in 50% ethanol and propolis extract in saline (group TNBS-P), propolis extract in saline (group SP),(More)
Alterations in the gastrointestinal neuromuscular function related to age have been demonstrated in human and animal models. This study analyzes the effects of the aging process on the area of the neuronal cell bodies of the myenteric plexus in the antimesenteric and intermediate regions of the ileal circumference of Wistar, 12 month-old in comparison 3(More)
