Background and Aim: Momordica charantia is mainly characterized by its antimicrobial and antioxidant properties. The current study aimed to evaluate the healing activity of gel and cream formulations based on M. charantia on induced wounds in mice. Materials and Methods: Acetonic extract of M. charantia was prepared and incorporated into gel and cream formulations. Mus musculus Balb/c (n=30) with induced injury were distributed into five groups: Group I (control – day 7), Group II (control – day 14), Group III (1% gel – day 7), and Group IV (1% gel – day 14) to which 1% M. charantia gel was dermally applied daily for 7 and 14 days, respectively, Group V (1% cream – day 7) and Group VI (1% cream – day 14) to which of M. charantia 1% cream were dermally applied daily for 7 and 14 days, respectively. Time of wound closure was determined during the experimentation; rats were euthanized with sodium pentobarbital 60 mg/kg/pc v.ip. for obtaining skin samples for histopathological analysis. Results: Groups IV and VI showed a higher percentage of wound closure on day 14, and in histopathological analysis, effect was greater in Group VI with the presence of fibroblasts and abundant collagen and elastic fibers. Conclusion: M. charantia gel and cream showed wound healing activity on induced wounded mice; the most effective treatment was M. charantia 1% cream formulation.

Fluid extract of leaves of Tessaria integrifolia Ruiz & Pav. presents leishmanicidal activity on Mesocricetus auratus with experimental leishmaniasis. Fraction F8 presents leishmanicidal activity on infected macrophages at a dose of 14 μg/mL. An eudesman type sesquiterpene was identified, according to 1 H, 13C, and LC / MS NMR analysis.

Learning and memory are linked, but they are different. Learning is a process by which knowledge about the environment is acquired and memory is the process by which knowledge is encoded, consolidated, stored and then retrieved. [10][11] Coding involves processes by which newly learned information is received when it is for the first time.Consolidation is a process that modifies newly stored and still labile information to make it more stable for long-term storage. Consolidation involves the expression of genes and the synthesis of new proteins, resulting in structural changes that store memory in a stable way over time. Storage refers to mechanisms and places that retain information over time. Recovery are processes that enable the retrieval and use of stored information. [12][13][14] Various types of memory have been proposed over the years,

Background: Ipomoea batatas (L.) Lam. (I. batatas) is a root native from South America that is characterized by its antioxidant, antimicrobial and anti-inflammatory properties. These properties contribute to the wound healing process. Objective: To evaluate the healing activity of a gel based on I. batatas on dermal wound healing in mice. Material and methods: An acid ethanolic extract (1.5 N hydrochloric acid: Ethanol 96 ° 15:85, v / v) was prepared with the peels of the roots of I. batatas "purple sweet potato", which was incorporated into the formulations 0.5% and 1% gel. Mus musculus Balb / c with induced injury were distributed in four experimental groups: Group I (Control), which did not receive any treatment. Group II (Gel base), Group III (Gel I. batatas 0.5%) and Group IV (Gel I. batatas 1%) received the daily administration of topical treatments for 14 days. Wound closure was determined during the experimentation time, then they were euthanized with sodium pentobarbital 60 mg / kg / pc v.ip. to obtain skin samples for histopathological analysis. Results: Group IV shows a higher percentage of wound closure, which is also evidenced in histopathological changes. Conclusions: The 1% gel based on the ethanolic extract of the peels of the roots of Ipomoea batatas (L.) Lam. they show healing activity in wounds induced in mice, being the most effective treatment.
