Atorvastatin has no effects on kidney tissues of wistar albino rats in the long-term Intake: an electron microscopic Study / Atorvastatina no niene efectos sobre los tejidos renales de ratas wistar albinas en el consumo a largo plazo: un estudio de microscopia electrónica

In this study, we evaluated the ultrastructural findings of kidney with systemic administration of different doses of atorvastatin in a rat model. Statins may have anti-inflammatory effects that would play a role in preventing the cellular damage. The aim of this study was to investigate how atorvastatin could play a role in kidney tissues. Forty adult male Wistar albino rats (200­250 g) were randomly divided into 4 groups of ten rats each (A1, A2, A3 and Control). Three different doses of atorvastatin were used to determine the effects on kidney tissues during 90 day period. The kidneys of A1 (0.1-mg group), A2 (0.5-mg group) and A3 (1-mg group) group were excised and the tissues were examined after the 90 days by transmission electron microscopy. Despite increasing the dose of atorvastatin intake, the histological structures of atorvastatin groups were appeared normal in the same period. In conclusion, long-term use of atorvastatin was not found to have an adverse effect on kidney tissue.

En un modelo de rata, se evaluaron los hallazgos ultraestructurales del riñón provocados por la administración sistémica de diferentes dosis de atorvastatina. Las estatinas pueden tener efectos anti-inflamatorios que desempeñan un importante rol en la prevención del daño celular. El objetivo de este estudio fue investigar cómo la atorvastatina podría desempeñar un papel en los tejidos del riñón. 40 Ratas Wistar albinas Adultas (200-250 g) machos fueron divididas aleatoriamente en cuatro grupos de 10 ejemplares cada uno (A1, A2, A3 y Control). Tres diferentes dosis de atorvastatina se utilizaron para determinar los efectos sobre los tejidos del riñón durante un período de 90 días. Los riñones de los grupos A1 (0,1 mg), A2 (0,5 mg) y A3 (1 mg) fueron extirpados a los 90 días y los tejidos examinados por microscopía electrónica de transmisión. A pesar de haberse aumentado la dosis de ingesta de atorvastatina, las estructuras histológicas se asemejaron al grupo normal del mismo período. En conclusión, el uso de atorvastatina en un plazo prolongado, no produce efecto negativo sobre el tejido renal.

Coexisting of aortic arch variation of the left common carotid artery arising from brachiocephalic trunk and absence of the main branches of right subclavian artery: a review of the literature.

The variations in the aortic arch and its branches are of surgical interest. Many anomalies of the aortic arch and great vessels are uncovered as serendipitous findings on imaging studies, in the anatomy laboratory, or at surgery. A 56-year-old woman had an arch angiogram as part of an evaluation for cardiovascular disease. A two-vessel left aortic arch was identified consisting of the brachiocephalic trunk and left subclavian artery. In this study, we present a case of the left common carotid (LCC) artery arising from the brachiocephalic trunk (BT) and absence of the main branches of right subclavian artery in her angiographic imaging findings. There is no previous report about LCC artery arising from BT and absence of the main branches of right subclavian artery in the same person.

The demonstration of the inferior sternal cleft using three-dimensional reconstruction: a case report.

Congenital sternal cleft is a rare disorder in which there is a gap in the midline of the anterior chest wall between the two halves of the sternum. Typically, the contour of the mediastinal structures can be seen beneath the skin. It is rare and the exact incidence is not known. It results from failure of fusion of the two lateral mesodermal sternal bars by 8 weeks of gestation. Most cases are diagnosed shortly after birth and are reported only rarely in adults. We report here one of the congenital major chest wall deformities; inferior sternal cleft is rarely seen, associated with sternal and costal variations in a 22-year young man.
