As a source of biologically active compounds, buckwheat has beneficial effects in nutrition due to its high content of flavonoids, particularly rutin. Aim of our study was to examine effects of buckwheat on plasma lipid status and phospholipids fatty acids composition, histological and parameters of oxidative stress in Wistar rats fed a high-fat diet. This study showed that buckwheat leaf and flower (BLF) mixture supplementation significantly reduce weight gain, plasma lipid concentrations and atherogenic index in rats fed a high-fat diet. Treatment of the high-fat group of animals with buckwheat significantly increased percentage of n-6 fatty acids as well as eicosapentaenoic acid (EPA) and decreased percentage of saturated fatty acids (SFA) and oleic acid. Buckwheat antioxidant effects diminished negative influence of high-fat diet in hyperlipidemic rats, while pathohistological analysis of liver confirmed changes after high-fat consumption. Our results showed hypolipidemic, antiatherogenic and antioxidative features of buckwheat leaf and flower mixture, and these parts of the plant with the highest rutin content could be beneficial in prevention and curing of hyperlipidemia.
BACKGROUND: “VITALPLANT” medicinal plant mixture, aimed at body weight regulation and metabolism enhancement was formulated in order to be incorporated as an ingredient in functional food formulations on the basis of known biological activity of the alder buckthorn bark, peppermint, caraway and parsley. METHODOLOGY: The body weight-lowering potential, hypolipidemic effects and antioxidant activity of “Vitalplant” mixture were examined on five groups of male Wistar rats on different food regimes for 14 weeks. RESULTS: “Vitalplant” mixture supplementation caused an increase in food intake, but induced a decrease in body weight gain. The lipid status and atherogenic index (AI) were significantly improved in “Vitalplant” mixture supplemented hyperlipidemic (HF) groups in comparison to HF group. “Vitalplant” mixture was able to influence the activity of antioxidant enzymes and to protect erythrocytes of the rats fed the HF diet from oxidative damage, which was indicated by significantly lower malondialdehyde (MDA) levels in “Vitalplant”- HF groups in comparison to the HF group. CONCLUSION: “Vitalplant” mixture seemed to be beneficial for the reduction of body weight and improvement of antioxidant status of the erythrocytes, and its antihyperlipidemic property was highly active for enhancing the profile of plasma lipids in rats.
In spite of its benign behaviour and mostly asymptomatic clinical course it is necessary to consider cavernous hemangioma in the differential diagnosis of other pulmonary lesions. The definitive diagnosis can be made only by histopathological and immunohistochemical examination.
Although confirmation of the diagnosis is difficult, a combination of characteristic clinical, radiological and histological findings and either serological results positive for Aspergillus or the isolation of Aspergillus from respiratory samples are highly indicative of CNPA.
Sclerosing hemangioma of the lung is a rare benign tumor that can metastasize to regional lymph nodes. It is a neoplasm that originates from type II pneumocytes and primitive respiratory epithelium. It is most common in middleaged women in form of peripherally localized node. Tumor is composed of two types of cells, and there are papillary, solid, sclerotic, and hemorrhagic histological pattern. Preoperative and intraoperative diagnosis of the tumor is difficult. In a 53-old female patient, radiologically was discovered hyperdense nodule with smooth margins, which was followed for two years, and then underwent enucleation of the tumor. The tumor was 25 mm in diameter and consisting of round and cuboidal cells. Microscopically, it showed papillary and solid arrangement. Based on immunohistochemical analysis, we made a diagnosis of sclerosing hemangioma of the lung. Three months after surgery, the patient was in good health condition. Because of the numerous differential diagnostic dilemmas, diagnosis is almost always based on permanent paraffin sections, using a wide range of immunohistochemical analysis. Type of surgery depends on the tumor location, and in case of larger tumors, lymph node dissection needs to be done as well.
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.
