ABSTRACT
Medicinal plants are rich in nutrients and phytochemicals which prevent and treat a wide range of ailments. Accumulating experimental studies exhibit that some bioactive ingredients extracted from medicinal plants have suitable therapeutic effects on hepatic and renal injuries. This review focuses on the hepato- and reno-protective effects of thymoquinone, crocin, and carvacrol. The relevant literature was retrieved from PubMed, Scopus, Web of Science, and Google Scholar databases from the beginning of 2015 until the end of November 2021. According to the scientific evidence, the considered phytochemicals in this review have been applied with useful therapeutic effects on hepatic and renal damage. These therapeutic effects were mainly mediated through the amelioration of oxidative stress, suppression of inflammatory responses, and inhibition of apoptosis. Intracellular signaling pathways linked to nuclear factor kappa B (NF-κB), adenosine monophosphate-activated protein kinase, c-jun N-terminal kinase, and extracellular signal-regulated kinase 1/2 and Toll-like receptors are the most important pathways targeted by these phytochemicals. Up-regulation of transcription factor Nrf2 and down-regulation of transforming growth factor-beta 1 by these natural compounds also contribute to the alleviation of hepatic and renal injuries.
ABSTRACT
Introducción: La Enfermedad Renal es un problema de salud mundial. El Factor de Crecimiento Epidérmico actúa como citoprotector y trófico reparador. Objetivo: Evaluar el efecto reno-protector y reno-reparador del Factor de Crecimiento Epidérmico en biomodelo de Insuficiencia Renal Crónica. Material y Métodos: Se estudiaron 120 ratas, Wistar, en 6 grupos: Control Negativo y positivo, Solución Salina Dosis Única y Múltiple, Factor de Crecimiento Epidérmico Dosis Única y Múltiple. Se aplicó para efecto reno-protector dosis única antes del daño, y para el reno-reparador dosis múltiples posterior al daño, a razón de 100 µg/kg de peso. Resultados: La creatinina, urea y ácido úrico disminuyeron significativamente en los grupos experimentales, con mayor disminución para el grupo experimental dosis única, por lo que el efecto reno-protector fue mayor que el reno-reparador para los esquemas de tratamiento utilizados. Conclusiones: El Factor de Crecimiento Epidérmico mostró efecto reno-protector y reno-reparador al disminuir las variables hematológicas de daño renal(AU)
Introduction: Kidney disease is a world health problem. Epidermic Growth Factor acts as cyto-protector, and trophic restorative. Objective: To assess the reno-protective and reno-restorative effect of the Epidermal Growth Factor in biomodel of Chronic Renal Failure. Material and Methods: 120 Wistar rats were studied in 6 groups: Negative and Positive Control, Saline Solution Single-Dose and Multiple-Dose, Epidermal Growth Factor Single-Dose and Multiple-Dose. A single dose was applied before the damage for the reno-protective effect, and multiple doses after the damage for the reno-restorative effect, at a rate of 100 µg/kg of weight. Results: Creatinine, urea, and uric acid diminished significantly in the experimental groups, with a higher decrease for experimental group with single dose; therefore, the reno-protective effect was higher than reno-restorative one for the treatment patterns used. Conclusions: Epidermal Growth Factor showed reno-protective and reno-restorative effect by diminishing the hematological variables in kidney damage(AU)
