The analyses on the imaging examinations were performed with the aid of the same computer software as had been used for image acquisition. In accordance with the manufacturer's recommendations, the apparatus was calibrated using a phantom that the manufacturer supplied. The following imaging options were selected: appendicular type I bone high-resolution mode 76 kVp 150 μA collimation at the fine adjustment and areas of standardized size comprising 40 mm in width and 20 mm in length. The images were all acquired with the femurs in the same position, immersed in water at a depth of 2 cm. Densitometric analysis The right femurs were subjected to analysis in a dual-emission X-ray densitometer for small animals (Lunar ® DPX Alpha). The animals and the specimens were weighed simultaneously.Īfter weighing and measurement, the structures were kept in chilled saline solution until the day of the densitometric analysis and mechanical tests (not more than 48 h after the dissection). They were then anesthetized by means of intramuscular injection of xylazine hydrochloride (95 mg/kg) and ketamine hydrochloride (12 mg/kg) and sacrificed by means of exsanguination, using cardiac puncture., The right and left femurs of each animal were extracted from their body segments and the muscle and connective tissues were totally removed.

Experimental design during the exposure period.Įl Aprendiz De Sabio Pdf Gratis. Given that there is evidence that prolonged use of PPIs may change the behavior of bone cells, our objective here was to analyze the bone mineral density and mechanical properties of rat femurs that were subjected to long-term use of omeprazole. Therefore, the relationship between using PPIs and bone demineralization and the risk of fractures associated with prolonged use of omeprazole remains unclear. Suggested that using omeprazole would tend to diminish bone reabsorption and impede the progression toward osteoporosis. Cara Download File Shutterstock Gratis here. It is believed that the mechanism responsible for this consists of elevation of gastric pH, which would interfere with calcium absorption., This occurs because some salts, such as calcium, are insoluble in basic pH and would therefore be absorbed less readily. Reported that administration of omeprazole (20 mg/day), which is one of the most important PPIs, is capable of significantly diminishing bone mineral density (BMD). Epidemiological studies have indicated that there is a relationship between prolonged use of PPIs and bone metabolism, although this relationship is still not totally established. Introduction Proton pump inhibitors (PPIs) are the main drugs used for treating diseases such as duodenal ulcers and reflux esophagitis., Because these drugs present few adverse effects when administered correctly, they have come to be used not only for acute symptoms in clinical practice, but also for long-term purposes, even though such indications are highly debatable., PPIs act mainly toward suppressing gastric acid secretion by the parietal cells of the stomach, since they inhibit the enzyme H + K + ATPase, and this acid suppression may last for up to 48 h.
