Effect of naringerin on biochemical parameters in the streptozotocin-induced diabetic rats
Fernandes, Ana Angélica Henrique;Novelli, Ethel Lourenzi Barbosa;Fernandes Junior, Ary;Galhardi, Cristiano Machado;
Brazilian Archives of Biology and Technology , 2009, DOI: 10.1590/S1516-89132009000100007
Abstract: amongst the numerous co-adjuvant therapies which could influence the incidence and progression of diabetic complications, antioxidants and flavonoids are currently being tested in clinical trials. we investigated the effect of naringerin on biochemical parameters in streptozotocin-induced (stz - 60 mg/kg, i.p.) diabetic rats. male rats were divided into four groups: g1: untreated controls; g2: normal rats receiving naringerin; g3: untreated diabetics; g4: diabetics rats receiving naringerin. the naringerin (50mg/kg, i.p,) decreased the hyperglycaemia and hyperlipidaemia associated with stz-diabetes. the concentrations of serum insulin in treated diabetic rats tended to be increased. naringerin treatment prevents stz-induced changes in the activities of alt, ast and ldh in the liver and heart, indicating the protective effect of naringerin against the hepatic and cardiac toxicity caused by stz. the glycogen level in cardiac and hepatic tissues elevated with naringerin in diabetic rats. the naringerin can improve the glucose and lipid metabolism and is beneficial in preventing diabetic complications.

Abstract: the objective of this study was to determine the prevalence of overweight and obesity, the correlation between body mass index (bmi) and indices: waist hip ratio (whr) and waist circumference (cc) and to compare between genders, the relationship between the indices in patients of down syndrome (ds) aged 15 to 44 years. the sample consisted of 33 individuals of ds residents in the cities of itaperuna - rj and bom jesus itabapoana - rj, being 15 females aged between 14 and 38 years (mean ± sd, 23.8 ± 7.4 years, bmi = 29.67 ± 5.64 kg/m2) and 18 males aged between 14 and 44 years (mean ± sd, 26.4 ± 8.4 years, bmi = 27.68 ± 5.97 kg/m2). the anthropometric measures of body mass, height, waist and hip, were used to obtain the bmi, the whr and wc. the level of association between variables was obtained by spearman and pearson tests. the highest correlation coefficients between the variables bmi and wc in male groups (r = 0.926, p = 0.000), female (r = 0.874, p = 0.000) and overall (r = 0.892, p = 0.000). thus, the strongest associations between bmi and anthropometric indicators suggest that these cc integrated indicators are good predictors of general and central obesity, in patients with ds.

Brazilian Journal of Microbiology , 2006,
Abstract: The goal of this work was to investigate a possible synergistic effect between ethanolic extracts of propolis from Brazil and Bulgaria and some antibiotics (Amoxicillin, Ampicillin and Cefalexin) against Salmonella Typhi. Brazilian and Bulgarian propolis showed an antibacterial action, but the sample from Bulgaria was shown to be more efficient. Both samples showed a similar synergistic effect with these antibiotics. One may conclude that the propolis samples show an important antibacterial action, as well as a synergistic effect with antibiotics against Salmonella Typhi.

Abstract: As propriedades biológicas da própolis de Apis mellifera s o amplamente relatadas sendo comuns varia es nas mesmas em fun o da regi o onde foram produzidas. A a o antimicrobiana de própolis obtidas em três regi es do Brasil (Botucatu-SP, Mossoró-RN e Urubici-SC) foi investigada sobre linhagens isoladas de infec es clínicas humanas (Staphylococcus aureus, Escherichia coli, Enterococcus sp, Pseudomonas aeruginosa e Candida albicans). Foram preparados extratos alcoólicos de própolis (EAP) e determinada a Concentra o Inibitória Mínima (CIM) seguida do cálculo da CIM90%. A própolis de Botucatu foi a mais eficiente sobre S. aureus (0,3%v/v), Enterococcus sp (1,1%v/v) e C. albicans (2,1% v/v). Para E. coli, a própolis eficiente foi de Urubici (7,0%v/v) e para P. aeruginosa a de Mossoró (5,3%v/v). Os resultados mostram maior sensibilidade das bactérias Gram positivas e levedura em rela o às Gram negativas. é possível concluir que, para os microrganismos testados e amostras de própolis testadas, há diferen as na atividade antimicrobiana em fun o do local de produ o e que isso se explica pela diferen a de composi o química da própolis.

Abstract: surveys of the tree community, topography and soils of a fragment of tropical semideciduous forest were carried out with the purpose of assessing the impacts of a fire that struck the forest in 1999 on the community structure and tree species composition and diversity, as well as the relationship between fire severity and variables of the physical environment. the forest fragment, with an area of 57ha, is situated at 21o09's of latitude and 44o50'w of longitude, in the municipality of ibituruna, minas gerais state, brazil. the surveys were carried out in two sectors of the fragment. there were two surveys in the slope sector: the first, in 1997 (before the fire), within fifteen 5×50 m sample plots, and the second, in 2001 (after the fire), within thirteen 20×20 m sample plots. a single survey was carried out in the valley sector within thirteen 20×20 m sample plots distributed along the frontline, defined by the maximum fire propagation. the surveys registered the species, the circumference at breast height and the total height of trees with diameter at breast height (dbh) > 5 cm. topographic variables, soil chemical and textural variables, a fire damage index (fdi), and an edge factor were obtained for each sample plot. the fire caused considerable impacts to the arboreal component of the vegetation. tree density and total basal area decreased and this was particularly concentrated in the classes of smallest diameter and height. where fire severity was higher (> fdi), there were higher proportions of standing dead over surviving trees, expressed as both density and basal area. in the slope sector, the species of lower stature at maturity dropped in the rank of relative abundances after the fire. two years after the fire, there was an increase in tree species richness and diversity probably due to the addition of pioneer species in fire-opened areas. no correlations were detected between the fdi and the edge factor, not even any of the topographic or soil variables,
