ABSTRACT

Aims: To assess the therapeutic effect of curcumin supplementation in modulating the expression of NF-κB in the joints of collagen-induced arthritis (CIA) rats. Place and Duration of Study: Department of Postgraduate Studies and Research, International Medical University, between July 2011 and May 2012. Methodology: Arthritis was induced in each group of Dark Agouti (DA) rats, by intradermal injection with collagen emulsified in complete Freund’s adjuvant. Treatment groups which were induced with CIA were treated with: 500 mg/kg curcumin; 1000 mg/kg curcumin; 2000 mg/kg curcumin; 25 mg/kg aspirin. Combination treatment groups which were induced with CIA were treated with: 500 mg/kg curcumin and 25 mg/kg aspirin; 1000 mg/kg curcumin and 25 mg/kg aspirin; 2000 mg/kg curcumin and 25 mg/kg aspirin from day 25 to 38. Efficacy was assessed based on ability to reduce paw oedema, histopathological changes, NF-κB expression, serum tumour necrosis factor alpha (TNF- α), interleukin 1-beta (IL-1β) and gluthathione peroxidase (GPx) levels. Results: Based on histopathological study, immunohistochemical scoring of NF-κB and ELISA analysis of TNF-α, IL-1β and GPx levels, our study found that curcumin given after arthritis in high doses, shows effects of healing and this results were comparable to positive control group, which is the arthritic group treated with 25 mg/kg aspirin. Curcumin given in combination with aspirin, showed better reduction in pathology in arthritic group compared to positive control group, especially with higher doses of curcumin. Conclusion: Curcumin was effective in reducing inflammatory changes seen in CIA joints which were proved through histopathological, immunohistochemical and biochemical analysis, however only at high doses.

ABSTRACT

FUNDAMENTO: A diminuição da variabilidade da frequência cardíaca (VFC) está associada com um prognóstico desfavorável em pacientes com doença cardíaca isquêmica (DCI) e diabete. Ainda não foi provado em definitivo se a mudança no padrão respiratório pode modificar o fator de risco nesses pacientes. OBJETIVO: Avaliar o efeito da respiração diafragmática sobre a VFC em pacientes diabéticos com DCI. MÉTODOS: A população do estudo consistiu em 145 pacientes do sexo masculino selecionados ao acaso, dos quais 45 apresentavam DCI, 52 apresentavam DCI e diabete (DCI-DM) e 48 apresentavam DCI e neuropatia diabética (DCI-ND). A VFC foi avaliada através de ECG de 5 minutos usando o método de domínio de tempo. O grupo de intervenção foi dividido em grupo aderente e não-aderente e o seguimento foi registrado após três meses e um ano. RESULTADOS:A avaliação basal mostrou uma diminuição significante em VFC nos pacientes com doença cardíaca isquêmica com ou sem diabete (p<0,01). Os pacientes com DCI apresentavam VFC mais alta do que os pacientes com DCI-DM (p<0,01) e DCI-ND (p<0,01). Um aumento na VFC foi observado em pacientes que praticaram respiração diafragmática por três meses (DCI-DM: p<0,01; DCI-ND: p<0,05) e por um ano (DCI-DM: p<0,01; DCI-ND: p<0,01). A VFC diminuiu significantemente após um ano em pacientes não-aderentes. A prática regular de respiração diafragmática também melhorou o índice glicêmico nesses pacientes. CONCLUSÃO: A prática regular de respiração diafragmática melhora de forma significante a VFC em uma direção prognosticamente favorável em pacientes com DCI e diabete. Esses efeitos parecem ser potencialmente benéficos no manejo desses pacientes.


BACKGROUND: Reduced heart rate variability is associated with an unfavorable prognosis in patients with ischemic heart disease and diabetes. Whether change in breathing pattern can modify the risk factor in these patients has not been definitely proved. OBJECTIVE: To evaluate the effect of diaphragmatic breathing on heart rate variability (HRV) in ischemic heart disease patients with diabetes. METHODS: Study population consisted of 145 randomly selected male patients of which 45 had ischemic heart disease (IHD), 52 had IHD and diabetes (IHD-DM) and the remaining 48 had IHD and diabetic neuropathy (IHD-DN). HRV was assessed by 5 minute-electrocardiogram using the time domain method. The intervention group was divided into compliant and non-compliant groups and follow-up recording was carried out after three months and one year. RESULTS: Baseline recordings showed a significant decrease in HRV in ischemic heart disease (IHD) patients with or without diabetes (p<0.01). IHD patients had higher HRV than IHD patients with diabetes (p<0.01) or diabetic neuropathy (p<0.01). Increase in HRV was observed in patients who practiced diaphragmatic breathing for three months (IHD-DM: p<0.01; IHD-DN: p<0.05) and for one year (IHD-DM: p<0.01; IHD-DN: p<0.01). The HRV significantly decreased after one year in non-compliant patients. The regular practice of diaphragmatic breathing also improved the glycemic index in these patients. CONCLUSION: The regular practice of diaphragmatic breathing significantly improves heart rate variability with a favorable prognostic picture in ischemic heart disease patients who have diabetes. These effects seem to be potentially beneficial in the management of IHD patients with diabetes.

La VFC se evaluó a través de ECG de 5 minutos con el empleo del método de dominio de tiempo. El grupo de intervención se dividió en grupo adherente y no-adherente y se registró el seguimiento tras tres meses y un año. RESULTADOS: La evaluación basal reveló una disminución significante en VFC en los pacientes con enfermedades cardiaca isquémica con o sin diabetes (p<0,01). Los pacientes con DCI presentaban VFC más alta que los pacientes con DCI-DM (p<0,01) y DCI-ND (p<0,01).

La VFC disminuyó significantemente tras un año en pacientes no-adherentes. La práctica regular de respiración diafragmática también mejoró el índice glucémico en esos pacientes. CONCLUSIÓN: La práctica regular de respiración diafragmática mejora de forma significante la VFC en una dirección pronósticamente favorable en pacientes con DCI y diabetes. Esos efectos parecen ser potencialmente benéficos en el manejo de esos pacientes.
