We conclude that the optimal treatment of pulmonary sequestration is surgical resection to avoid infection and destruction of the normal pulmonary parenchyma, even in asymptomatic cases. Moreover, in the case of pulmonary infection and the destruction of normal tissue, major resection such as lobectomy or pneumonectomy may be considered, instead of limited resection.
Surgical resection for bronchiectasis can be performed with acceptable morbidity and mortality at any age. The involved bronchiectatic sites should be resected completely for the optimum control of symptoms.
The higher lung tissue elasticity and delayed symptoms due to localizations of the cyst are the reasons for the occurrence of giant hydatid cysts in the lung. A parenchyma-saving operation should be performed instead of anatomical resection because of the low complication rates and because most complications can be treated conservatively.
SummaryBackgroundProanthocyanidin is a bioflavonoid known to have protective effect against oxidative injury. We investigated the cardioprotective effect of proanthocyanidin.Material/MethodsThirty-two Rattus Norvegicus rats were categorized equally as the control group (CG), proanthocyanidin group (PCG), ischemia group (IG) and proanthocyanidin-treated group (PCT). Rats in CG and IG were fed standard rat food and PCG and PCT were fed standard rat food plus proanthocyanidin (100 mg/kg/day twice a day by oral gavage) for 3 weeks. In CG and PCG the myocardial samples were prepared immediately, and in IG and PCT hearts were placed in transport solution and kept at 4°C for 5 hours, then prepared for evaluation. Malondialdehyde (MDA) level, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities were measured.ResultsMDA levels were significantly higher in IG and PCT than in CG and PCG. The activity of SOD was significantly lower in IG and higher in PCG than in the other groups. The activity of GPx was significantly lower in IG than in the other groups. The activities of CAT were significantly lower in IG and PCT than in the other groups and were significantly lower in IG than PCT. Histopathologic evaluation revealed normal findings in CG and PCG. While ischemic injury was observed in IG, the content of muscle fibers was better preserved in PCT.ConclusionsProanthocyanidin may have a protective effect on myocardial ischemic injury.
BackgroundThe aim of the present study was to investigate the cardioprotective effect of Taurine on the donor hearts during cold ischemic period.Methods32 rats were divided into four groups (sham, taurine, ischemia, treatment group, 8 rats in each). All rats were fed with rat food for three weeks. Taurine and treatment groups were given a 200 mg/kg/day dose of Taurine by oral gavage besides rat feed. Cardiectomy was performed in all rats after three weeks. In ischemia and treatment groups, harvested hearts were kept in 0.9% sodium chloride at +4 degrees C for 5 hours. Tissue samples were taken from left ventricle in all groups. These samples were evaluated by histopathologic and biochemical examination.ResultsIn the present study results of the biochemical and histopathological examination reveals the protective effects of Taurine. As a marker of lipid peroxidation, Malondialdehyde (MDA) levels in ischemia group were significantly higher than both Sham and Taurine groups. MDA values were recorded; 3.62 ± 0.197 in the sham group, 2.07 ± 0.751 in the Taurine group, 9.71 ± 1.439 in the ischemia group and 7.68 ± 1.365 in the treatment group. MDA levels decreased in treatment group. (p < 0.05) In accordance with MDA findings, while superoxide dismutase and glutathione peroxidase levels decreased in ischemia group, they increased in treatment group. (p < 0.05) There was no differences in Catalase (CAT) enzyme level between treatment and ischemia group (p = 1.000). CAT level results were recorded; 7.08 ± 0.609 in the sham group, 6.15 ± 0.119 in the Taurine group, 5.02 ± 0.62 in the ischemia group, and 5.36 ± 0.384 in the treatment group. Less intracellular edema and inflammatory cell reaction were observed in histologic examination in favor of treatment group. (p < 0.01)ConclusionTaurine decreased myocardial damage during cold ischemic period following global myocardial ischemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
