Efeitos do laser sobre a cirrose hepática

Led enhancement in mitochondrial oxidative phosphorylation for hepatectomized rats

“…1,2,3 Both visible red light an infrared light have been shown to present many different effects at the cellular level. Light radiation must be absorbed 4 to promote a biological response; on this basis, we expected any type of light therapy to be an effect of light itself, and not a function of coherency which is a unique property of laser light.…”

“…With this in mind, we performed a series of experiments to demonstrate that the effects of low energy laser therapy are due to the effects of light and not to the unique properties of lasers. 2,3,5 The experiment here reported is a first and involves the observation of variations of respiratory cell function after irradiation with a light emitting diode (LED). Recently, the LED developed by the Optics Group of IFSC-USP has been used instead of laser for the treatment of skin tumors by the PDT (Photodinamic Therapy) (an effect not previously tested by other investigators) because of its low operational cost compared to the use of a laser.…”

Efeito da hepatectomia parcial associada à administração de fatores nutricionais hepatotróficos sobre a morfologia, função e expressão de genes pró-fibróticos na cirrose hepática em ratos Wistar induzida por tiocetamida

“…No entanto, a remoção do tecido hepático pode resultar em insuficiência hepática aguda (Hashimoto e Watanabe, 1999). Portanto, a hepatectomia é um procedimento temido em indivíduos com cirrose (Zimmermann e Reichen, 1998;Araújo-Lima et al, 2000;Moser et al, 2000;Wilasrusmee et al, 2004;Min et al, 2011) e a mortalidade após o procedimento aumenta nestes pacientes (Belghiti et al, 2000).…”
