BACKGROUND: A significant association of cola beverage consumption and increased risk of bone fractures has been recently reported. The present study was carried out to examine the relationship of cola soft drink intake and bone mineral density in ovariectomized rats. METHODS: Study 1. Four groups of 10 female Sprague-Dawley rats were studied. Animals from groups II, III, and IV were bilaterally ovariectomized. Animals from groups I and II received tap water for drinking, while animals from groups III and IV each drank a different commercial brand of cola soft drink. After 2 months on these diets, the following were measured: solid diet and liquid consumption; bone mineral density; calcium in bone ashes; femoral cortex width; calcium; phosphate; albumin; creatinine; alkaline phosphatase; 25-OH hydroxyvitamin D, and PTH. RESULTS: Study 2. Two groups of seven ovariectomized rats were compared. Group A animals received the same management as the group III animals from study 1 (cola soft drink and rat chow ad libitum), while rats from group B received tap water for drinking and pair-feeding. After 2 months plasmatic ionized calcium, phosphate, creatinine, albumin, calcium in femoral ashes, and femoral cortex width were measured.Study 1. Rats consuming cola beverages (groups III and IV) had a threefold higher liquid intake than rats consuming water (groups I and II). Daily solid food intake of rats consuming cola soft drinks was one-half that of rats consuming water. Rats consuming soft drinks developed hypocalcemia and their femoral mineral density measured by DEXA was significantly lower than control animals as follows: group I, 0.20 +/- 0.02; group II, 0.18 +/- 0.01; group III, 0.16 +/- 0.01, and group IV, 0.16 +/- 0.01 g/cm(2). Study 2. To rule out the possibility that these calcium and bone mineral disorders were caused by decreased solid food intake, a pair-fed group was studied. Despite a lower body weight, pair-fed animals consuming tap water did not develop bone mineral reduction or hypocalcemia. CONCLUSIONS: These data suggest that heavy intake of cola soft drinks has the potential of reducing femoral mineral density. 相似文献

The mission of the Heart Failure and Heart Transplantation Section of the Spanish Society of Cardiology is to study, promote interest in, and disseminate information about all aspects of myocardial dysfunction and heart transplantation. Heart failure is a highly prevalent disorder that consumes a substantial proportion of healthcare resources. Consequently, there is a very high level of interest in the condition and a wide range of preclinical and clinical research is being carried out, including research into new ways of looking at the disease that will increase our understanding. The aim of this article was to describe current developments concerning this disease and its treatment. Firstly, the latest publications on heart failure are summarized. Then, the most recent studies on advanced heart failure and ventricular assist devices are reviewed. Finally, the latest findings on heart transplantation are reported. 相似文献

Time Frames for Analysis of Inflammatory Mediators in Acute Pancreatitis: Improving Admission Triage
Andrés Duarte-Rojo Jorge Suazo-Barahona María Teresa Ramírez-Iglesias Luis F. Uscanga Guillermo Robles-Díaz 《Digestive diseases and sciences》2009,54(10):2282-2287
Improving the outcome of acute pancreatitis through prognostic markers has been a matter of ample research. We evaluate the
clinical usefulness of four serum markers in comparison to Ranson’s score. Serum measurements of C-reactive protein (CRP),
interleukin-6, -10 (IL-6, IL-10), and pancreatitis-associated protein (PAP) were performed. The usefulness of each marker
for predicting severity was compared with that of Ranson’s score. Time of evolution was considered for improving their usefulness.
Seventy-one patients were studied. Severe cases had higher levels of all markers, although only IL-10 had better accuracy
than Ranson’s. In patients admitted during the first 48 h, IL-6, IL-10, and PAP had improved accuracy over Ranson’s; however,
after this time frame, only CRP outperformed Ranson’s score. Analysis of time frames improved the accuracy of all markers.
Therefore, time of evolution should be considered when using these parameters for a better prognosis. 相似文献

Abstract.
Background Condyloma acuminata is the most
common anorectal lesion in patients infected with human
immunodeficiency virus (HIV). Surgical treatment can be
challenging in cases where the size and extension into the
anal canal make individual excision impossible. These
patients require large resections and reconstruction using
grafts or local flaps.Methods Six patients were treated
for giant perianal condylomas between 1999 and 2001.
Four patients were HIV–positive, and were selected for
surgical intervention after achieving a T4 count >350 and
low viral replication. In 5 cases, the lesions were circularly
resected up to the pectinate line and the defect was
reconstructed using a bilateral V–Y plasty. In the remaining
case, fulguration was possible on one side and a unilateral
V–Y plasty was performed.Results There were no
infections or healing delays in this series, and the functional
and aesthetic results are satisfactory.Conclusion V–Y
plasties are a valid method for perianal reconstruction
after resection of giant anal condyloma, with good results
in selected patients with HIV infection. 相似文献
