Fetuin-A is synthesized in the liver and is secreted into the bloodstream. Clinical studies suggest involvement of fetuin-A in metabolic disorders such as visceral obesity, insulin resistance, diabetes, and fatty liver. Curcumin is extracted from the rhizome Curcuma longa and has been shown to possess potent antioxidant, anticarcinogenic, anti-inflammatory, and hypoglycemic properties. In this study, we investigated the effect of curcumin treatment on serum fetuin-A levels as well as hepatic lipids and prooxidant–antioxidant status in rats fed a high-fat diet (HFD). Male Sprague–Dawley rats were divided into six groups. Group 1 was fed control diet (10 % of total calories from fat). Groups 2 and 3 were given curcumin (100 and 400 mg/kg bw/day, respectively ) by gavage for 8 weeks and were fed control diet. Group 4 was fed with HFD (60 % of total calories from fat). Groups 5 and 6 received HFD together with the two doses of curcumin, respectively. Curcumin treatment appeared to be effective in reducing liver triglycerides and serum fetuin-A levels. These findings suggest that the reduction of fetuin-A may contribute to the beneficial effects of curcumin in the pathogenesis of obesity. 相似文献

Quantitation of exact total protein content is often a key step and is common to many applications in general biochemistry research and routine clinical laboratory practice. Before embarking on any type of protein analysis, particularly comparative techniques, it is important to accurately quantitate the amount of protein in the sample. In order to assess the quality of total protein estimation results, five methods were tested and were applied to the same pooled plasma sample. For this aim, Bradford (Coomassie Brilliant Blue), Lowry (Folin-Ciocalteau), Biüret, Pesce and Strande (Ponceau-S/TCA), and modified method of Schaffner-Weismann (Amido Black 10B) were used. The last two methods employ simultaneous precipitation of proteins with the acid containing dye solutions followed by dissolution of precipitate in a NaOH solution. It is shown that each assay has advantages and disadvantages relative to sensitivity, ease of performance, acceptance in literature, accuracy and reproducibility/coefficient of variation. All of the methods tested show a CV % < 6. Besides pooled plasma, a known concentration of human serum albumin was also analyzed and discussed by means of standardization of plasma total protein content. 相似文献

Isolated ACTH deficiency is an uncommon cause of secondary adrenocortical insufficiency and accompaniment with primary empty sella has been reported in several cases. We present a case of isolated ACTH deficiency associated with empty sella. A sixty-two year old woman was admitted to our endocrine clinic with complaints of weakness, fatigue, weight loss, nausea, vomiting, and lack of appetite for about one month. Physical examination indicated orthostatic hypotension and epigastric tenderness. Laboratory investigations revealed hypoglycemia, hyponatremia and anemia, in addition low plasma cortisole and ACTH levels. Serum cortisole responses to short and prolonged ACTH stimulation were tested and partial and accurate responses were obtained, respectively. Plasma ACTH and serum cortisole levels failed to respond after intravenous injection of human corticotropin releasing hormone. Other hypophysial hormone levels were within the normal reference ranges. Although cranial and abdominal computerized tomography images were evaluated as normal, cranial magnetic resonance imaging of the pituitary gland revealed 'primary empty sella turcica'. Replacement therapy with methylprednisolon resulted in the improvement of hypoglycemia, hyponatremia and clinical symptoms. Based on these results, the patient was diagnosed as isolated ACTH deficiency and was scheduled for follow up by our outpatient clinic. Our report is consistent with other reports pointing out that primary empty sella may be responsible for pathogenesis of isolated ACTH deficiency. 相似文献

It has been proposed that salicylic acid (SA) acts as an endogenous signal molecule responsible for inducing abiotic stress tolerance in plants. The effect of varying salicylic acid (SA) supply (0, 0.1, 0.5 and 1.0mM) on growth, mineral uptake, membrane permeability, lipid peroxidation, H(2)O(2) concentration, UV-absorbing substances, chlorophyll and carotenoid concentrations of NaCl (40 mM) stressed maize (Zea mays L.) was investigated. Exogenously applied SA increased plant growth significantly both in saline and non-saline conditions. As a consequence of salinity stress, lipid peroxidation, measured in terms of malondialdehyde (MDA) content and membrane permeability was decreased by SA. UV-absorbing substances (UVAS) and H(2)O(2) concentration were increased by increasing levels of SA. SA also strongly inhibited Na(+) and Cl(-) accumulation, but stimulated N, Mg, Fe, Mn and Cu concentrations of salt stressed maize plants. These results suggest that SA could be used as a potential growth regulator to improve plant salinity stress resistance. 相似文献
