Artigo Effect of sildenafil in renal ischemia/reperfusion injury in rats(2010) Medeiros, Paulo José de; Neto, Arthur Villarim; Lima, Francisco Pignataro; Azevedo, Ítalo Medeiros; Leão, Layra Ribeiro de Sousa; Medeiros, Aldo CunhaArtigo Antioxidant activity and protective effect of Turnera ulmifolia Linn. var. elegans against carbon tetrachloride-induced oxidative damage in rats(Elsevier, 2012-12) Brito, Naira J.N.; López, Jorge A.; Nascimento, Maria Aparecida do; Macêdo, José B.M.; Silva, Gabriel Araujo; Oliveira, Cláudia N.; Rezende, Adriana Augusto de; Brandão-Neto, José; Schwarz, Aline; Almeida, Maria das GraçasThe present study aimed to determine whether the leaves of Turnera ulmifolia Linn. var. elegans extract exert significant antioxidant activity. The antioxidant activity of its hydroethanolic extract (HEETU) was evaluated by assessing (a) its radical scavenging ability in vitro, and (b) its in vivo effect on lipid peroxidation and antioxidant enzyme activities. The in vitro antioxidant assay (DPPH) clearly supported HEETU free radical scavenging potential. Moreover, glutathione content and antioxidant enzyme activities (glutathione peroxidase, superoxide dismutase and catalase) were significantly enhanced in CCl4- treated rats due to oral HEETU-treatment (500 mg/kg b.w.) over 7 and 21 days. In addition, an improvement was observed in lipid peroxidation and serum biochemical parameters (aspartate aminotransferase and alanine aminotransferase), indicating a protective effect against CCl4-induced liver injuries, confirmed by histopathological studies. The HEETU effect was comparable to the standard drug Legalon (50 mg/kg b.w.) under the same experimental condition. Quantitative analysis of the HPLC extract revealed the presence of flavonoids, wich mediate the effects of antioxidant and oxidative stress. In conclusion, extract components exhibit antioxidant and hepatoprotective activities in vitro and in vivo.Artigo Mycobacterium marinum infection simulating chromomycosis: a case report(Universidade de São Paulo (USP), 2020) Bezerra, Guilherme Holanda; Honório, Monica Larissa Padilha; Costa, Vivianne Lira da Camara; Vechi, Hareton Teixeira; Alves, Manoella do Monte; Britto, Maria Helena Marques Fonseca de; Rocha, Keyla Borges Ferreira; Carvalho, Luciana Distásio deSkins infections caused by Mycobacterium marinum occur only rarely. We report one case of chronic and extensive M. marinum cutaneous infection simulating chromoblastomycosis and review the pertinent literature. A 52-year-old farmer reported a 32-year chronic skin problem on his right lower limb, resulting from contact with cacti. It consisted of skin lesion presenting with dyschromic atrophic center plate and verrucous borders with hematic crusts, extending from the knee anteriorly to the inferior third of the right leg. Mycobacterium marinum infection was detected by histopathological examination of a skin fragment, culture for mycobacteria and genetic mapping of the culture material. The patient was successfully treated with Ethambutol, Rifampicin and Trimethoprim-Sulfamethoxazole. The clinical and histopathological findings of M. marinum infection is nonspecific showing clinical polymorphism and bacilli are rarely evident on histopathological examination. Given these difficulties, it is essential to perform tissue culture in a suspicious case and it is important keep this infection in mind in patients with long-lasting indolent verrucous lesions and a history of exposure to sea water, freshwater, aquaria or fish
