Baltodano T., Juan E. Yaipen Ch. y César M. Fuertes R. DOI: https://doi.org/10.33017/RevECIPeru2009.0028/ RESUMEN En el presente trabajo se estudió el efecto cicatrizante del quitosano, obtenido por desacetilación a partir de quitina de los caparazones del cangrejo de la variedad Cancer cetosus «Cangrejo Peludo», bajo la forma farmacéutica de ungüento a diferentes concentraciones. Para ello se aisló la quitina de los caparazones de cangrejos, se obtuvo el quitosano por desacetilación y se identificó por método espectrofotométrico (IR), solubilidad y determinando el grado de desacetilación mediante titulación potenciométrica y posteriormente se formuló el ungüento. Para la determinación del efecto cicatrizante se utilizó el test de cicatrización descrito por Howes y col, para heridas incisas, en el cual se emplearon 48 ratones albinos hembras de la especie Mus músculos de 1 mes y medio de edad, con un peso dentro del rango de 25 a 33g. Las muestras se administraron cada 12 horas por un periodo de 72 horas, al término del cual se cuantificó la resistencia que ofrecían las heridas tratadas, comparándolas con sus respectivos controles y se realizaron cortes histológicos para observar el grado de evolución histológica del proceso de cicatrización. El quitosano, obtenido por desacetilación a partir de quitina presenta mayor efecto cicatrizante bajo la forma farmacéutica de ungüento al 0,25% (79,28% efecto cicatrizante) en comparación con el grupo control (base del ungüento) se concluye que en las condiciones de ensayo el quitosano posee un significativo efecto cicatrizante. ABSTRACT In the present work the wound healing effect of the chitosan was studied, the chitosan obtained for desacetylation of chitin from the crab´s shells of the variety Cancer cetosus «Shaggy Crab «, under the pharmaceutical form of unguent at different concentrations. For it there was isolated the chitin from the shell of crabs, the chitosan was obtained for desacetylation and identified by spectrophotometric method (IR), solubility, determining the degree of desacetylatión by way of potentiometric qualifications and later the unguent was formulated. For the determination of the wound healing effect we used the test of wound healing described by Howes and col., for incision wounds; we used 48 female albino mice of the species Mus músculos of 1 month and a half of age, with a weight inside the range of 25 to 33g. The samples were administrated every 12 hours for a period of 72 hours., at the conclusion of the experiment the resistance that the treated wounds were offering, was quantified verifying them with their respective controls and histological cuts were realized to observe the degree of histological evolution of the process of wound healing. The chitosan, obtained by desacetylation from Chitin presents major wound healing activity under the pharmaceutical form of unguent at 0,25% (79,28% wound healing effect) in comparison with the group control (base of the unguent), it is concluded that under the test conditions chitosan possesses a significant healing wound effect.

Rich amount of phenolic compounds are available in Trianthema portulacastrum L. (TP) leaves and are traditionally utilized as a wound dressing material. Oxidative stress and inflammation affect the Wnt/β-catenin pathway by modulating the glycogen synthase kinase-3β (GSK) activity subjected to delay in wound healing. The objective of the current study was to explore the wound healing effect of ferric oxide nanoparticles biosynthesized with fractionated TP extract (FeTP). The ability of TP active components (polyphenols) to inhibit the GSK was explored by using molecular docking studies. FeTP were synthesized, characterized, utilized to prepare an ointment and its efficacy was investigated against full-thickness dermal wounds. Different wound healing parameters, level of enzymatic antioxidants, hydroxyproline content and tissue cytokines level were analyzed. Histopathology was performed to confirm the healing by newly formed tissue architecture. Rats treated with FeTP showed significantly swift healing with faster wound contraction rate, high tensile strength and hydroxyproline content along with the utilization of less time for epithelialization. Histopathological study also validated the potential wound healing effect of FeTP with complete re-epithelialization. The results of the present study cumulatively revealed that the green synthesized FeTP ointment approach may serve as a potential tool for dermal wound healing.
