Analysis of Myenteric Neurons of the Cecum of Diabetic Rats After Supplementation with Ascorbic Acid International Journal of Morphology
Zanoni,Jacqueline Nelisis; Pereira,Priscila Goncalves Cardoso; dos Santos Pereira,Marli Aparecida.
The objective of this work was to investigate the neuroprotective action of the ascorbic acid over the myenteric neurons in the cecum of Wistar rats, four months after induction of the diabetes mellitus experimental with streptozotocin. Three groups with five rats each were used: C- controls, D- diabetic, DA- diabetic treated with ascorbic acid. For evidentiation of the myenteric neurons was carried out to Giemsa's technique. Were evaluated the areas of cell bodies of 500 neurons in each group studied. The quantitative analysis was carried out in an area of 16.6 mm2 in each cecum studied. In the animals diabetic observed elevation of the glycemia and glycated hemoglobin. The supplementation with ascorbic acid was effective under the myenteric neurons of...

Morphometry and Quantification of the Myenteric Neurons of the Cecum of Rats (Rattus norvegicus) Submitted to Experimental Chronic Alcoholism International Journal of Morphology
Pereira,Marli Aparecida dos Santos; Miranda Neto,Marcílio Hubner; Arantes,Márcia Alessandra; Molinari,Sonia Lucy; Pereira,Priscila; Zanoni,Jacqueline Nelisis.
Morphometric and quantitative analyses were accomplished to study the effects of the consumption of alcohol above the size and density of the myenteric neurons of cecum of rats. Ten rats with 90 days were divided in the groups: control (C), and alcoholic (A). After 120 days of treatment with ethanol the cecum of both groups were collected, submitted it prepared of membranes that after carried out to Giemsa´s technique, permitted to evaluate the neuronal density, in an area of 13.44mm², and measure the cell body area of 300 neurons by group. The alcoholic rats presented an increase in the number of small neurons and a reduction of the big and medium neurons. The neuronal density verified in alcoholic rats was significantly reduced regarding the controls...

Wheat bran- but not oat bran-enriched diets increase the mucosal height of the cecum and colon of newly weaned and aged rats BJMBR
Cavaglieri-Felippe,C.R.; Polacow,M.L.O.; Campos,M.R.; Vecchia,M.G.; Curi,R..
The effect of diets enriched with oat or wheat bran (prepared by the addition of 300 g of each fiber to 1000 g of the regular diet), given for 8 weeks, on the mucosal height of the colon and cecum was investigated. Newly weaned (21 days old) and aged (12 months old) male Wistar rats were used in this study. As compared to controls, diets enriched with wheat bran provoked a significant increase in the mucosal height, whereas oat bran did not cause any effect. In newly weaned rats (21 days old), wheat bran increased the mucosal height (µm) in the cecum by 20% (mean ± SEM for 8 rats; 169.1 ± 5.2 and 202.9 ± 8.0 for control and wheat bran, respectively) and in the colon (218.8 ± 7.2 and 264.5 ± 18.8 for control and wheat bran, respectively). A similar effect...
