Resumen
Objective: To determine whether the galactooligosaccharide stimulates calcium absorption in partially gastrectomized rats. Methods: Animals were submitted to laparotomy (sham-operated control) and partial gastrectomy (Billroth II) in groups of 20. They were fed a control diet (AIN-93M) without galacto-oligosaccharide or a diet containing (galacto-oligosaccharide - 50g/kg diet) for eight weeks. The animals were divided into four groups: sham-operated and non-gastrectomized with galactooligosaccharide, shamoperated and gastrectomized without galactooligosaccharide. On the final day of the study, whole blood was collected for determination of serum calcium concentration. Results: In the group with galactooligosaccharides calcium excretion in feces was significantly lower than the group without prebiotics. The apparent absorption of calcium in gastrectomized and normal rats was higher in groups fed with galactooligosaccharide than in the control diet group. Conclusion: The ingestion of galactooligosaccharides prevents osteopenia in partially gastrectomized rats. 38 3 186 191 Axelson, J., Persson, P., Gagnemo-Persson, R., Håkanson, R., Importance of the stomach in maintaining calcium homeostasis in the rat (1991) Gut, 32 (11), pp. 1298-1302 Koga, S., Nishimura, O., Iwai, N., Kishi, K., Takeuchi, T., Hinohara, T., Clinical evaluation of long-term survival after total gastrectomy (1979) Am J Surg, 138 (5), pp. 635-639 Nilas, L., Christiansen, C., Christiansen, J., Regulation of Vitamin D and calcium metabolism after gastrectomy (1985) Gut, 26 (3), pp. 252-257 Hara, H., Suzuki, T., Aoyama, Y., Ingestion of the soluble dietary fibre, polydextrose, increases calcium absorption and bone mineralization in normal and total-gastrectomized rats (2000) Br J Nutr, 84 (5), pp. 655-661 Ohta, A., Ohtsuki, M., Baba, S., Adachi, T., Sakata, T., Sakaguchi, E., Calcium and magnesium absorption from the colon and rectum are increased in rats fed fructooligosaccharides (1995) J Nutr, 125 (9), pp. 2417-2424 Ohta, A., Ohtsuki, M., Hosono, A., Adachi, T., Hara, H., Sakata, T., Dietary fructooligosaccharides prevent osteopenia after gastrectomy in rats (1998) J Nut, 128 (1), pp. 106-110 Rémésy, C., Levrat, M.A., Gamet, L., Demigné, C., Cecal fermentations in rats fed oligosaccharides (inulin) are modulated by dietary calcium level (1993) Am J Physiol, 264 (5 PART. 1), pp. G855-G862 Hara, H., Nagata, M., Ohta, A., Kasai, T., Increases in calcium absorption with ingestion of soluble dietary fiber, guar-gum hydrolysate, dependo on the caecum in partially nephrectomized and normal rats (1996) Br J Nutr, 76 (5), pp. 773-784 Chonan, O., Watanuki, M., Effect of galactooligosaccharides on calcium absorption in rats (1995) J Nutr Sci Vitaminol, 41 (1), pp. 95-104 Chonan, O., Watanuki, M., The effect of 6'-Galactooligosaccharides on bone mineralization of rats adapted to different levels of dietary calcium (1996) Int J Vitam Nutr Res, 66 (3), pp. 244-249 Chonan, O., Takahashi, R., Watanuki, M., Role of activity of gastrointestinal microflora in absorption of calcium and magnesium in rats fed beta1-4 linked galactooligosaccharides (2001) Biosci Biotechnol Biochem, 65 (8), pp. 1872-1875 Hirama, Y., Morohashi, T., Sano, T., Maki, K., Ohta, A., Sakai, N., Yamada, S., Sasa, R., Fructooligosaccharides prevent disorders of the femoral neck following gastrectomy in growing rats (2003) J Bone Miner Metab, 21 (5), pp. 294-298 Reeves, P.G., Nielsen, F.H., Fahey Jr., G.C., AIN-93 purified diets for laboratory rodents: Final report of the American Institute of Nutrition ad hoc writing committee on the reformulation of the AIN-76A rodent diet (1993) J Nut, 123 (11), pp. 1939-1951 Shiga, K., Nishimukai, M., Tomita, F., Hara, H., Ingestion of difructose anhydride III, a non-digestible disaccharide, prevents gastrectomyinduced iron malabsorption and anemia in rats (2006) Nutrition, 22 (7-8), pp. 786-793 Sakai, K., Aramaki, K., Takasaki, M., Inaba, H., Tokunaga, T., Ohta, A., Effect of dietary short-chain fructooligosaccharides on the cecal microflora in gastrectomized rats (2001) Biosci Biotechnol Biochem, 65 (2), pp. 264-269 Sakai, K., Ohta, A., Shiga, K., Takasaki, M., Tokunaga, T., Hara, H., The cecum and dietary short-chain fructooligosaccharides are involved in preventing postgastrectomy anemia in rats (2000) J Nut, 130 (6), pp. 1608-1612 Zittel, T.T., Zeeb, B., Maier, G.W., Kaiser, G.W., Zwirner, M., Liebich, H., High prevalence of bone disorders after gastrectomy (1997) Am J Surg, 174 (4), pp. 431-438 Santos, E.F., Tsuboi, K.H., Palu, B.F., Araujo, M.R., Andreollo, N.A., Miyasaka, C.K., Partial gastrectomy associated to anterior truncal vagotomy: Alterations in metabolism of the calcium (2009) Experimental study in rats ABCD Arq Bras Cir Dig, 22 (2), pp. 105-109 Santos, E.F., Tsuboi, K.H., Araújo, M.R., Ouwehand, A.C., Andreollo, N.A., Miyasaka, C.K., Dietary polydextrose increases calcium absorption in normal rats (2009) ABCD Arq Bras Cir Dig, 22 (4), pp. 201-205 de Prisco, C., Levine, S.N., Metabolic bone disease after gastric bypass surgery for obesity (2005) Am J Med Sci, 329 (2), pp. 57-61 Schölmerich, J., Postgastrectomy syndromes-diagnosis and treatment (2004) Best Pract Res Clin Gastroenterol, 18 (5), pp. 917-933
