«Obtención, caracterización y diseño de una forma farmacéutica semisólida (ungüento) a base de quitosano con efecto cicatrizante» «Obtención, caracterización y diseño de una forma farmacéutica semisólida (ungüento) a base de quitosano con efecto cicatrizante» Lady C. 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.

Injuries and wounds are any sorts of damage to the skin or subcutaneous tissue. Usually, any wounds of such sorts are self-healed. Sometimes, there may be a delay in healing, and that delay is caused due to the functional delays in various processes of wound healing. All the Ficus plants show similar activities like the antioxidant, anti-inflammatory and wound healing properties 7including skin conditions like ulcers and rheumatism. The anthelmintic property and immunomodulatory are also seen. The herbal extracts of the same family of Ficus in different plants were investigated for the wound healing activity in the excision wound method, and the extracts showed significant activity compared to the drug. All the extracts showed a better healing ability, but the extract of FBO-100 showed the highest activity followed by FMO followed by FHO and finally the FRO. Overall, the activity of the extract ointment was comparable and was significant compared to the standard drug ointment. The wound closure of the extract ointment treated groups were better and were completed in 12 days, and the activity was more than 96%. The herbal extracts of the same family of Ficus in different plants were investigated for the wound healing activity in the excision wound method, and the extracts showed significant activity compared to the drug. The plants of microcarpa, benghalensis, religiosa and hispida are compared for the activity, and the order showed for the activity was FBO>FMO>FHO>FRO.

Spirulina is a microalga used in traditional folk medicine in Morocco for the treatment of various health disorders. The wound healing activity of Moroccan Spirulina is unknown. In the current study, aqueous extracts of Spirulina platensis were investigated for acute toxicity and wound healing activity in Swiss Albino mice and White New Zealand rabbits, respectively. The LD50 (amount of substance required to kill 50% of the test population) of the microalga was greater than 5,000 mg/kg. Healing after application of the same amount of ointment on differently induced (mechanical, chemical, and thermal) wounds was about the same, over five weeks. Aqueous extract had remarkable healing activity on rabbits’ skin, possessing significantly greater healing effect for mechanical and chemical burns than controls. Moreover, the hair growing time was faster in treated groups; Spirulina-treated groups did not show any contamination with microbes compared to others. This study affirms that Spirulina platensis can be considered as a potential therapeutic agent for wound healing not only as a complementary medicine but also in conventional medicine.
