The benefit of Silybum marianum in ethanol-induced reprotoxicity of male Wistar rat

Abstract This study investigates the toxic effects of ethanol (Eth) on the reproductive system of male rats and the possible protective role of Silybum marianum seeds-infused solution (SMI) over six consecutive weeks of administration. Animals were divided into the following groups: control, SMI positive...

A influência de macrófagos M1, M2 e TAM, e do receptor P2X7 na invasividade e resistência de neuroblastoma

O neuroblastoma é um tumor sólido muito comum em crianças. O estágio mais avançado da doença é altamente agressivo e invasivo, além de pouco responsivo à terapia, que é limitada por mecanismos de resistência e reincidência relacionados à metástase. Muitos estudos tem sido feitos para identi...

Efecto antimicrobiano in vitro de extractos de Caesalpinia Spinosa (algarrobo) sobre patógenos orales

La resistencia antimicrobiana es un problema de sa-lud pública mundial. Las infecciones por microorga-nismos resistentes pueden ser altamente transmisi-bles e incluso causar la muerte. Este hecho genera grandes costos para los pacientes y para los servi-cios de salud. El objetivo del presente trabajo fu...

The neuroprotective effects of Lutongkeli in traumatic brain injury rats by anti-apoptosis mechanism

Acta cir. bras; 37 (6), 2022
Purpose: To explore the neuroprotective effects of Lutongkeli (LTKL) in traumatic brain injury (TBI) and detect the related mechanism. Methods: TBI model was established with LTKL administration (2 and 4 g/kg/d, p.o.). Motor function of rats was examined by Rotarod test. Nissl staining was used to show ...

Jatrorrhizine reduces myocardial infarction-induced apoptosis and fibrosis through inhibiting p53 and TGF-β1/Smad2/3 pathways in mice

Acta cir. bras; 37 (7), 2022
Purpose: To explore the mechanism of jatrorrhizine on apoptosis and fibrosis induced by myocardial infarction (MI) in an animal model. Methods: The left anterior descending branch of coronary artery was surgically ligated to duplicate the mouse model of MI. The sham and infarcted mice were treated with ...

Liver regeneration after extensive hepatectomy in rats: effect of preoperative chemotherapy with intravenous 5-fluorouracil

Acta cir. bras; 37 (9), 2022
Purpose: To evaluate the effect of preoperative intravenous chemotherapy with 5-fluorouracil on liver regeneration in an experimental model of major hepatectomy in rats. Methods: Wistar rats were divided into two groups of 20 animals each and submitted to 70% hepatectomy 24 h after intravenous injection...

Walnut ointment promotes full-thickness burning wound healing: role of linoleic acid

Acta cir. bras; 37 (9), 2022
Purpose: To investigate the active ingredients of walnut ointment (WO) and its mechanism in repairing wounds. Methods: The ingredients of WO were detected by gas chromatography–mass spectrometry. The effect of linoleic acid (LA) was tested by in vitro Alamar Blue (AB) reagent. Image J software, histol...

Purpose: To evaluate the effects of rosemary leaf essential oil-based ointments on the healing of rat skin lesions. Methods: Sixty adult male rats, with dorsal excisional skin wounds made surgically under anesthesia, were divided into three groups (n = 20): Sham group (untreated wounds); control group (...

Effect of trans-resveratrol on oxidative stress biomarkers associated with atherosclerosis

Growing evidence indicates that oxidative stress plays an important role in the pathophysiology of many cardiovascular diseases, including atherosclerosis. In this context, the use of bioactive compounds with antioxidant action can bring health benefits, especially in the prevention and control of pathop...

Quantificação de substâncias do fator de hidratação natural (NMF) do estrato córneo ex vivo em função do fototipo e idade

A hidratação cutânea ocorre, em parte, pelos componentes do Fator de Hidratação Natural (NMF), originados da degradação da filagrina, sendo alguns exemplos o ácido pirrolidona-carboxílico (PCA), o ácido urocânico (UCA) e a histidina (His). Estes estão presentes no estrato córneo (EC). O obje...
