Context: Maytenus macrocarpa (Chuchuhuasi) has long been employed in Peru as a traditional alternative therapy for several diseases, including cancer, arthritis and diarrhea. Recent studies show that several species of Maytenus have effects on nociceptive and inflammatory signaling, as well as toxic effects on behavioral neuronal pathways. Aims: The aim of this study is to evaluate the anti-inflammatory effects and neurobehavioral side manifestations of the leaf of Maytenus macrocarpa (Ruiz and Pav{\'o}n) Briquet. Methods and Materials: Experimental study, double blind. 60 male albino mice strain Balb/c were divided in ten groups and each group, was orally feed with different doses of ethanolic extracts of Maytenus macrocarpa (500, 750, 1000, 1250 and 1500 mg/kg), others group received distilled water, caffeine 32 mg/kg, diazepam 32 mg/kg, diclofenac 15 mg/kg and the last group without substance. Neurobehavioral effects were assessed by the Irwin test. The anti-inflammatory activity was measured by the Carrageenan paw oedema test. Statistical analysis was performed with ANOVA test and Fisher exact test. Results: Anti-inflammatory effects of M. macrocarpa were observed in a non-significant trend of dose dependent form. M. macrocarpa displayed an anti-inflammatory effect at 1250 mg/kg and these effects were higher in comparison with diclofenac (74.14\% vs 58.62\%, one way ANOVA, p\<0.05). Neurobehavioral side effects secondary to M. macrocarpa therapy were also identified, these included excitation, abnormal gait, abdominal cramps, piloerection, stereotypes and scratching (Fisher exact, p\<0.05, CI 95\%). Conclusion: M. macrocarpa leaves presented anti-inflammatory activity and concomitants neurobehavioral side effects.

Introduction: Maytenus macrocarpa (Chuchuhuasi) is an Amazonian Peruvian traditional plant, traditionally used as anti-inflammatory, antipyretic, antihemorrhagic and antidiarrheic agent. Also, chuchuhuasi is known as a master plant, attributing to it properties in the central nervous system. In addition, depression is a disorder of the mood that cause disability to millions of people around the world. For this reason, the aim of this study was to determinate the antidepressant and antipsychotic-like activity of the ethanolic extract of Maytenus macrocarpa. Methods: It was used the ethanolic extract of the leaves of Maytenus macrocarpa (EELMM) in female mice at the experimental model of the Forced Swim Test described by Porsolt. As control, it was used distillate water, fluoxetine and haloperidol. Results: The immobility time of the groups of EELMM has a mean of 38.26 \± 21.57, 84.32 \± 26.68 and 32.17 \± 25.55 for the doses of 750, 1000 and 1250 mg/Kg respectively; and the immobility time had a median of 7.5 [4.07 \– 20.3] and 20.93 \± [17.63 \– 23.75] for the doses of 500 mg/Kg and 1500 mg/Kg. It was seen a positive dose-response between the dose of 500 to 1000 mg/Kg (Pearson correlation of r=0.8339 and R=0.6954) and a negative dose-response between the dose of 1000 to 1500 mg/Kg. (Pearson correlation of r= -0.7590 and R= 0.5760). Conclusion: It was demonstrated the antidepressant-like activity of the ethanolic extract of the leaves of Maytenus macrocarpa with a dose of 500 mg/kg and an antipsychotic-like activity with a dose of 1000 mg/kg.

Introduction: Jatropha curcas L. seeds are used in traditional medicine to treat a variety of diseases or conditions. The aim of this study is to evaluate effects on inflammation and the nervous system of ethanol extract of J. curcas seeds. Materials and methods: It was used 64 mice divided in 8 groups; respectively, 4 groups received 400, 600, 800 and 1000 mg/kg of ethanol extract of J. curcas seed; and the rest intake Diclofenac, Diazepam, Caffeine and a control group not received any substance. The effects on inflammation was evaluated by Carrageenan-Induced paw oedema test and by Paw skin temperature. Neurological symptoms of toxicity were evaluated using the Irwin test. For the analysis of quantitative variables were used the following tests: one-way ANOVA, Tukey, Shapiro-Wilk and Pearson correlation; for qualitative variables Chi square was used. Results: According to the paw oedema, it was showed a trend on an inflammatory effect of the seeds of J. curcas; this activity was statistically significant in doses of 1000 mg/kg. Also, the skin temperature measurements outcomes reveal a positive dose response manner. Regard to neurological manifestations, Straub tail was founded in doses of 400 mg/kg. Stereotypies were founded in doses of 400, 600, 800 and 1000 mg/kg throughout the evaluation. Conclusion: J. curcas seeds were showed an inflammatory effect. In addition, effects on the nervous system were founded as stereotypes and Straub tail.
