Estudo comparativo entre cinco diferentes tratamentos sobre as alterações clínicas e laboratoriais do rato diabético induzido pela aloxana

The long-term effects of five different treatments of diabetes were evaluated in alloxan-induced diabetic rats. Seven experimental groups, with 50 rats each (GN--normal control; GD--untreated diabetic control; GI, GA, GIA--treated groups with insulin, acarbose, and insulin plus acarbose, respectively; GTIL, GTPD--treated groups with islet of Langerhans and pancreas transplantation) were studied. Clinical (body weight, water intake, food intake and urine output) and laboratory (blood and urinary glucose, and plasma insulin) parameters were analyzed at the beginning of the study, and after 1, 3, 6, 9 and 12 months of follow-up. Mortality was observed in all groups, except GN, during 12 months (GD = 50%; GI = 20%; GA = 26%; GIA = 18%; GTIL = 4%; GTPD = 20%). Rats from the GD, GI, and GIA groups died due to metabolic or hydrossaline disbalance, and/or pneumonia, diarrhoea, and cachexy. All deaths observed in GTIL and GTPD groups were in decorrence of technical failure at the immediate postoperative, until 72h. Animals from the GI, GA and GIA had significative improving of the clinical and laboratory parameters (p < 0,05) observed in diabetic rats, being the efficacy of theses treatments equal. However, rats from the GTIL and GTPD groups had better control of these parameters than GI, GA, and GIA groups. Transplanted rats had complete restoration, at the normal levels, of all analyzed variables (p < 0.01). Conventional treatments with insulin, acarbose, and insulin plus acarbose improved the severe diabetic state of the alloxan-diabetic rats, but pancreas and islet transplantation have a better performance for treatment of diabetes.

Hypothalamic energy metabolism is impaired by doxorubicin independently of inflammation in non-tumour-bearing rats

We sought to explore the effects of doxorubicin on inflammatory profiles and energy metabolism in the hypothalamus of rats. To investigate these effects, we formed two groups: a control (C) group and a Doxorubicin (DOXO) group. Sixteen rats were randomly assigned to either the control (C) or DOXO groups. The hypothalamus was collected. The levels of interleukin (IL)-1β, IL-6, IL-10, TNF-α and energy metabolism (malate dehydrogenase, complex I and III activities) were analysed in the hypothalamus. The DOXO group exhibited a decreased body weight (p < 0.01). Hypothalamic malate dehydrogenase activity was reduced when compared with control (p < 0.05). In addition, pro-inflammatory cytokine levels were unchanged. Therefore, our results demonstrate that doxorubicin leads to an impairment of \hypothalamic energy metabolism, but do not affect the inflammatory pathway. Copyright © 2015 John Wiley & Sons, Ltd. Conflict of Interest Significance paragraph The hypothalamus is a central organ that regulates a great number of functions, such as food intake, temperature and energy expenditure, among others. Doxorubicin can lead to deep anorexia and metabolic chaos; thus, we observed the effect of this chemotherapeutic drug on the inflammation and metabolism in rats after the administration of doxorubicin in order to understand the central effect in the hypothalamus. Drug treatment by doxorubicin is used as a cancer therapy; however the use of this drug may cause harmful alterations to the metabolism. Thus, further investigations are needed on the impact of drug therapy over the long term.

Estudo comparativo entre cinco diferentes tratamentos sobre as alterações clínicas e laboratoriais do rato diabético induzido pela aloxana

OBJETIVOS: Este estudo visa a analisar os efeitos, a longo prazo, de cinco diferentes tratamentos sobre o controle metabólico de ratos diabéticos aloxânicos. MÉTODOS: Foram analisados 7 grupos experimentais, com 50 ratos cada um, sendo: GN o grupo controle normal; GD o grupo controle diabético, sem tratamento; GI, GA e GIA os grupos tratados, respectivamente, com insulina, acarbose e associação insulina + acarbose; GTIL o grupo tratado com transplante de ilhotas de Langerhans; e o GTPD o grupo tratado com transplante pancreatoduodenal heterotópico. Parâmetros clínicos (peso, ingestão hídrica, ingestão alimentar e diurese) e laboratoriais (glicemia, glicose urinária e insulina plasmática) foram avaliados em todos os animais, no início do experimento, e após 1, 3, 6, 9 e 12 meses de seguimento. RESULTADOS: À exceção do GN, mortalidade foi observada em todos os grupos experimentais no seguimento de 12 meses (GD= 50%; GI= 20%; GA= 26%; GIA= 18%; GTIL= 4%; GTPD= 20%). em GD, GI, GA e GIA os óbitos ocorreram por distúrbios metabólicos ou hidroeletrolíticos e/ou pneumonia, diarréia e caquexia; em GTIL e GTPD todos os óbitos ocorreram por falhas técnicas no pós-operatório até 72h. Animais dos grupos GI, GA e GIA tiveram melhora significativa (p < 0,05) de todos os parâmetros clínicos e laboratoriais observados em ratos diabéticos, sem diferença de efetividade entre os tratamentos. Porém, os resultados observados nestes grupos, biologicamente não foram comparáveis aos observados em GTIL e GTPD, onde observou-se correção completa, aos níveis normais, de todas as variáveis analisadas (p<0,01). CONCLUSÕES: Os tratamentos convencionais com insulina, acarbose e insulina + acarbose melhoraram o estado diabético grave dos ratos tratados, contudo, a eficácia dos tratamentos foi significativamente inferior à oferecida pelo GTIL e GTPD.

Avaliação do consumo alimentar e percepção da imagem corporal de culturistas

In bodybuilding, sport that emerged in Brazil in the 70s, competitors are judged by physical appearance, size and muscle definition. The present study aimed to assess dietary intake, supplement use, and it also investigated body image perceptions of bodybuilders. Practitioners of three different gyms in the state of São Paulo participated in the study. They filled the anamnesis form containing data on food consumption and intake of supplements and also answered a questionnaire on the perception of body image (Satisfaction Scale with Body Appearance). The study showed a considerable food inadequacy with an average of carbohydrate intake of 41.84% ± 10.88%, of lipid, an average of 18.96% ± 6.40% and of protein 39.20% ± 10.41%. In pre-competition, the average of daily carbohydrate intake is reduced to 22.69% ± 12.34%, the lipid increases to 25.68% ± 14.0% and the protein increases to 51.63% ± 10.28%. It was observed that all individuals take some sort of supplement. Considering the perception of body image 60% of the appraised are fully satisfied with the muscular appearance and 40% has greater risk of developing vigorexia. As the bodybuilder has rigid dietary control, it is important nutritional monitoring. So it is necessary a better identification and guidance of risk groups for the development of body image disturbances through specialized professionals such as dieticians, psychologists and coaches for success training, aiming at physical and mental well being of the athletes.
