Abstract
BACKGROUND AND AIM Maytenus ilicifolia has analgesic, healing, antioxidant and anti-inflammatory properties. This study evaluated effect of the hydroalcoholic extract of M. ilicifolia leaves on skin wound repair. EXPERIMENTAL PROCEDURE Wounds were induced on mice and treated with the extract. The treatment was performed daily, until day 7 after wound induction. Wound closure was measured and the features of the repaired tissue were investigated, including mast cell quantification, neutrophil and macrophage activities, collagen deposition, angiogenesis, and pro-metalloproteases and metalloproteases 2 and 9 activity (pro-MMPs and MMPs). RESULTS AND CONCLUSION The M. ilicifolia extract accelerated the closure of wounds. The extract at a concentration of 4% was found to be effective, presenting anti-inflammatory effects and hemoglobin increased, along with increased soluble, total and type III collagens in the wound. In addition, there was an increase in pro-MMP9 and MMP9 activity after day 7th of treatment. The phenolic compounds and tannins present in this plant could be associated with the anti-inflammatory and healing activities observed in this study. Therefore, the ability to modulate essential parameters for accelerated and adequate healing as shown here suggests that the use of standardised extracts of M. ilicifolia and its fractions enriched in polyphenols may represent a therapeutic strategy for the treatment of wounds.

Effects of the aqueous extract of Phyllanthus niruri Linn during pregnancy and lactation on neurobehavioral parameters of rats' offspring. JOURNAL OF ETHNOPHARMACOLOGY 2021; 270:113862. [PMID: 33484906 DOI: 10.1016/j.jep.2021.113862] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Revised: 12/29/2020] [Accepted: 01/18/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Phyllanthus niruri L. (Phyllanthaceae) is a plant used in traditional medicine, mainly to treat kidney stones. However, the effects of maternal exposure to P. niruri remain poorly explored. AIM OF THE STUDY The objective of this study was to investigate the effects of administration of aqueous extract of P. niruri (AEPN) during pregnancy and lactation, in maternal toxicity, reflex maturation, and offspring memory. MATERIALS AND METHODS Pregnant rats were divided into three groups (n = 8/group): Control (vehicle), AEPN 75, and AEPN 150 (each respectively treated with P. niruri at a dose of 75 and 150 mg/kg/day). The animals were treated via intragastric gavage during pregnancy and lactation. Weight gain, feed intake, and reproductive performance were analyzed in the mothers. In the offspring, the following tests were performed: Neonatal Reflex Ontogeny, Open Field Habituation Test and the Object Recognition Test in adulthood. RESULTS Maternal exposure to AEPN did not influence weight gain, feed intake, or reproductive parameters. In the offspring, anticipation of reflex ontogenesis (time of completion) was observed (p < 0.05). During adulthood, the AEPN groups presented decreases in exploratory activity upon their second exposure to the Open Field Habituation Test (in a dose-dependent manner) (p < 0.05). In the Object Recognition Test, administration of the extract at 75 and 150 mg/kg induced significant dose-dependent improvements in short and long-term memory (p < 0.05). CONCLUSION Administration of the AEPN accelerated the reflex maturation in neonates, and improved offspring memory while inducing no maternal or neonatal toxicity.
