Influência da Calcarea phosphorica e do alendronato sódico na remodelação óssea de ratas ovariectomizadas

Abstract

A osteoporose é uma doença crônica degenerativa caracterizada por deterioração progressiva e silenciosa da microarquitetura óssea, que requer tratamento, pois aumenta o risco de fraturas. Entre os medicamentos mais utilizados para tratar osteoporose estão os bifosfonatos como o alendronato. Na literatura, há poucos trabalhos que descrevam a ação de medicamentos homeopáticos com possível indicação para o tratamento da osteoporose. O objetivo deste trabalho foi analisar a ação da Calcarea phosphorica em comparação à ação do alendronato sódico na remodelação óssea no fêmur de ratas com deficiência estrogênica. Foram utilizadas 120 ratas divididas em quatro grupos de 30 animais. Aos três meses de idade, três grupos foram submetidos à ovariectomia (OVZ) e um grupo à falsa castração (Sham). Após 60 dias os tratamentos foram iniciados de acordo com os seguintes grupos: Sham com placebo, OVZ com placebo, OVZ com Calcarea phosphorica 6CH (2 glóbulos/ml de água/dia/animal) e o OVZ com alendronato sódico (1,2mg/kg/três vezes/semana/animal). Os animais em grupo de 6 foram sacrificados após 3, 6, 10, 17 e 28 dias de tratamento. O fêmur direito de cada animal foi submetido às analises, histomorfométrica do volume ósseo no colo do fêmur e imunohistoquímica para osteocalcina. Os resultados mostraram que os animais tratados com Calcarea phosphorica responderam ao tratamento com estímulo à proliferação de osteoblastos e aumento de volume ósseo no colo do fêmur enquanto o tratamento com alendronato influiu apenas na diminuição de reabsorção óssea. Concluiu-se que o tratamento com Calcarea phosphorica é valido para o controle da remodelação óssea na osteoporose

Ostoporosis is a chronic degenerative disease characterized by bone loss due to progressive damage in the bone microarchitecture. It requires treatment because of the increased risk of fractures. There are few reports describing the effects of homeopathic medication on bone remodeling regarding its possible application in the treatment of osteoporosis. The aim of this study was to analyze the effect of Calcarea phosphorica in comparison to Alendronate on bone remodeling of the proximal area of femurs of osteoporotic rats. For that 120 rats 3 months old were used, divided in 4 groups of 30 animals. Three groups went through bilateral ovariectomy in order to induce osteoporosis, and one group had a sham surgery to become a control group. After 60 days the following treatments began: Sham treated with placebo, ovariectomized treated with placebo, ovariectomized treated with Calcarea phosphorica 6CH (2 globules/1 ml of water/day/animal) and ovariectomized treated with Alendronate sodium (1,2mg/kg/3 times a week/animal). The animals (n= 6) were sacrificed after 3, 6, 10, 17 and 28 days of treatment. The right femur was removed, and representative sections of the femoral epiphysis and trocanter area were selected to histomorphometric and imunohistochemical analyzes. The results showed that the animals treated with the homeopathic remedy Calcarea phosphorica 6CH had a positive response with proliferation of osteoblasts while treatment with alendronate had effect on the osteoclasts inhibiting bone resorption. It is concluded that treatment with Calcarea phosphorica is valid to control bone remodeling in osteoporosis
