Aging is the crucial co-morbidity that prevents the full cardioprotection against myocardial ischemia/reperfusion (I/R) injury. Combination therapy as a promising strategy may overcome this clinical problem. This study aimed to investigate the cardioprotective effects of Ginsenoside compound-Mc1 (GMc1) and Dendrobium Nobile Lindl (DNL) in myocardial I/R injury and explore the involvement of the TLR4/NF-κB signaling pathway in aged rats. In vivo I/R injury and myocardial infarction was established by temporary coronary ligation in 22–24 months’ old Sprague Dawley male rats. GMc1 (10 mg/kg) and DNL (80 mg/kg) were administered intraperitoneally for 4 weeks and orally for 14 days, respectively, before I/R injury. Infarct size was measured through triphenyl-tetrazolium-chloride staining. ELISA assay was conducted to quantify the levels of cardiotroponin, and myocardial content of TNF-α and glutathione. Western blotting was employed to detect the expression of TLR4/MyD88/NF-κB proteins. GMc1 and DNL significantly reduced the infarct size to a similar extent ( p < 0.05) but their combined effect was greater than individual ones ( p < 0.01). Combination therapy significantly restored the left ventricular end-diastolic and developed pressures at the end of reperfusion as compared with the untreated group ( p < 0.01). Although the GMc1 and DNL reduced the levels of inflammatory cytokine TNF-α and increased the contents of antioxidant glutathione significantly, their individual effects on the reduction of protein expression of TLR4/MyD88/NF-κB pathway were not consistent. However, their combination could significantly reduce all parameters of this inflammatory pathway as compared to untreated I/R rats ( p < 0.001). Therefore, the combined treatment with GMc1 and DNL increased the potency of each intervention in protecting the aged hearts against I/R injury. Reduction in the activity of the TLR4/MyD88/NF-κB signaling pathway and subsequent modulation of the activity of inflammatory cytokines and endogenous antioxidants play an important role in this cardioprotection.

Dendrobium nobile Lindl. (olho-de-boneca) é uma das orquídeas mais populares do Brasil, ocupando posição de destaque no mercado de plantas de corte e de vaso. Entretanto, o desenvolvimento muito lento da família Orchidaceae tem contribuído para o elevado valor unitário de suas plantas, sendo necessárias técnicas que promovam a obtenção mais rápida de plantas comercializáveis. Objetivando avaliar o efeito do ácido giberélico no alongamento de plantas de D. nobile, foi realizado experimento em delineamento inteiramente casualizado com cinco concentrações de GA3 (0, 50, 100, 200 e 400 mg.L-1) e treze repetições. Efetuaram-se quatro pulverizações com soluções de ácido giberélico a intervalos quinzenais e noventa dias após início dos tratamentos, avaliaram-se as seguintes características: altura e diâmetro do pseudobulbo, número de folhas, largura e comprimento das folhas. A aplicação do GA3 promoveu, em comparação às plantas testemunhas, incrementos de 64,08% em altura e 44,27% no comprimento das folhas e decréscimos de 50% no diâmetro do pseudobulbo e 56,09% na largura das folhas. Não houve diferença entre as concentrações de GA3 testadas. Portanto, o ácido giberélico nas concentrações de 50 a 400 mg.L-1 é igualmente eficiente no alongamento de plantas D. nobile.
