RESUMO

Although several studies have been conducted to elucidate the relationship between psychedelic consumption and cognition, few have focused on understanding the long-term use influence of these substances on these variables, especially in ritualistic contexts.  To verify the influence of ritualistic ayahuasca consumption on the cognition of experienced ayahuasca religious users (> 20 years) and beginners (< 3 years), which participated in rituals of the Centro Luz Divina (CLD), a Santo Daime church in Brazil. Observational, descriptive, and cross-sectional study was carried out in which 48 people participated divided into three groups: (a) experienced ayahuasca users (n = 16), (b) beginner ayahuasca users (n = 16) and (c) control group (n = 16). All groups were matched by sex, age, and education and contained 8 women and 8 men. Cognition was assessed with the WASI (intelligence quotient), Digit Span (verbal working memory), Corsi Block-Tapping Task (visuospatial-related and working memory), Rey-Osterrieth Complex Figure test (visual perception, immediate memory), and Wisconsin Card Sorting and Five Digit Test (executive functions). Groups were homogenous in terms of sociodemographic characteristics, with participants presenting average intellectual performance. There was no evidence of cognitive decline amongst ayahuasca users. The experienced group showed higher scores compared to the less experienced group in the Digit Span and Corsi Block-Tapping tasks, which assess working verbal and visuospatial memories respectively. We confirmed the botanical identities of Psychotria viridis and Banisteriopsis caapi and the presence of the alkaloids both in the plants and in the brew. Short and long-term ayahuasca consumption does not seem to alter human cognition, while long-term use seems to be associated with improvements in aspects of working memory when compared with short-term use.

RESUMO

Some of the vernacular or scientific names are related to possible medicinal and/or toxic properties that can reveal the presence of potential bioactive agents, contributing to the discovery of new drugs and/or knowledge of the risks associated with their use. This study sought to list the scientific and vernacular names of plants whose lexicons are related to those possible properties of plants and to compare them with the "ethno" (ethnobotanical and ethnopharmacological) and pharmacological data available in the scientific literature. A floating reading of the two classical and reference works on Brazilian medicinal plants was performed, and plants with vernacular and/or scientific names related to the possible medicinal and/or toxic properties were listed. Correlations between the meanings of the species' names (lexicon) and their possible biological properties were made from their translation from Latin by consulting dictionaries. A bibliographic survey was conducted on the "ethno" and pharmacological data for each species. Finally, data from these three dimensions (lexicon, "ethno," and pharmacology) were classified and compared using a bioprospection classification. It resulted in a list of 90 plant species belonging to 47 families. 66 of the 90 species presented "ethno" data from the scientific literature, while 46 species presented pharmacological data. Of these, 46 (69.7%) and 27 (58.7%), respectively, showed equivalence with the possible medicinal and/or toxic properties of plants according to their lexicons. According to this study, half of the plants investigated demonstrate equivalence in the three dimensions analyzed (lexicons, "ethno," and pharmacological data from the scientific literature). Gastrointestinal and nervous system categories are among the most common in all three dimensions. Plant lexicons may be closely linked to the possible medicinal and/or toxic properties and the study of plant lexicons may represent one more approach for the search for new drugs, mainly considering the gastrointestinal, nervous, and parasites categories.

RESUMO

Ethnobotanical studies that use the participatory research approach seek to involve the residents of a community in different stages of the study, promoting the registration, dissemination and strengthening of local knowledge, as well as the empowerment of decisions related to the sustainable use and management of resources. Using the participatory methodology, this study recorded and made a comparative analysis on the use of plants in two quilombola communities (Quilombo do Cambury-QC and Quilombo da Fazenda-QF) in the State of São Paulo. After a training on anthropological and botanical methods, local researchers selected and interviewed the local experts, recording their knowledge on plant uses and collecting the indicated plants, to be identified and deposited in herbariums. In addition, participant observation and field diaries were used by the academic researchers, helping to analyze the data. To test the differences in the composition of species known to local community, a Jaccard dissimilarity matrix was created, and a Permanova test was employed. During the 178 days of fieldwork, three local researchers from the QC and two from the QF, selected nine and eight experts on the uses of the plants in each quilombo, respectively, corresponding to 214 plant species, indicated for eight ethnobotanical categories. Our hypothesis has been confirmed, since the traditional knowledge found in both quilombos, regarding plant uses and the number of plant species by category, are distinct, since each community occupies particular plant areas and different phytophysiognomies. Most of the indicated species are native to the Atlantic forest, and no significant differences were observed in the proportion of native species vs. introduced among quilombos for any of the categories of use studied. Furthermore, the innovative methodology used, participatory ethnobotany, contributed to the empowerment of community members with regard to the use of their available resources in the environment in which they live, while retaining the intellectual property rights over their own knowledge.

RESUMO

Doxiciclinaé um fármaco do grupo das tetraciclinas indicado para tratamento de diferentes doenças, em principal a coriza infecciosa. Entretanto, antimicrobianos do grupo das tetraciclinas tem capacidade de se ligarem e indisponibilizar minerais importantes para a formação dos ovos. O objetivo do projeto foi de avaliar a interferência da doxiciclina na qualidade de ovos comerciais. Realizou-se um estudo com 100 poedeiras Dekalb Brown®onde se avaliou a cor da gema, unidade Haugh, cor da casca, peso e espessura da casca. O delineamento adotado foi o inteiramente casualizadosem um esquema fatorial 2x2, resultando nos tratamentos: sem doxiciclina ao 5° dia; com doxiciclina ao 5° dia; sem doxiciclina ao 10° dia; com doxiciclina ao 10° dia. Coletou-se 4 ovos por repetição,totalizando 48 ovos analisado por tratamento em cada um dos períodos analisados. Não foram encontradas diferenças significativas entre os tratamentos para as variáveis de qualidade interna dos ovos (cor da gema e unidade Haugh). Para as variáveis de qualidade de casca, houve uma redução significativa dos níveis de amarelo com o uso de doxiciclina por 10 dias, além da redução do peso da casca e da espessura apical e equatorial da casca, principalmente no 10º dia e com o uso de doxiciclina. Conclui-se que o uso da doxiciclina não interfere na qualidade interna dos ovos, porém confere tonalidade acinzentada as cascas, e redução de peso e espessura das mesmas.(AU)


Doxycycline is a drug from the tetracycline group indicated for the treatment of different diseases, mainly infectious coryza. However, antimicrobials from the tetracycline group can bind and make minerals important for egg formation unavailable. The aim of this project is evaluated interference of doxycycline in quality of commercial egg. A study had carried out with 100 Dekalb Brown®laying hens where evaluated the yolk color, Haugh unit,color eggshell, weight and thickness eggshell. The delimitation had completely randomized in a 2x2 factorial scheme, resulting in treatments: without doxycycline at day 5; with doxycycline a day 5; without doxycycline at day 10; with doxycycline at day 10. Four eggs had gathered per replicate, totaling 48 eggs analyzed per treatment in each of the analyzed periods. No significant differences were found between treatments for internal egg quality variables (yolk color and Haugh unit). For the shell quality variables, there was a significant reduction in yellow levels with the use of doxycycline for 10 days, in addition to a reduction in shell weight and apical and equatorial shell thickness, mainly on the 10th day and with the use of doxycycline. It is concluded that the use of the doxycycline does not interfere in the internal quality of the eggs, but it gives a greyish tonality to the eggshells, and reduces their weight and thickness.(AU)


La doxiciclina es un fármaco del grupo de las tetraciclinas indicado para el tratamiento de diferentes enfermedades, principalmente el coriza infeccioso. Sin embargo, los antimicrobianos del grupo de las tetraciclinas tienen la capacidad de unirse y hacer que minerales importantes para la formación de huevos no estén disponibles. El objetivo de este proyecto es evaluar la interferencia de la doxiciclina en la calidad del huevo comercial. Se realizó un estudio con 100 gallinas ponedoras Dekalb Brown®donde se evaluó el color de la yema, unidad Haugh, color del cascarón, peso y grosor del cascarón. La delimitación tuvo completamente al azar en un esquema factorial 2x2,resultando tratamientos: sin doxiciclina en el día 5; con doxiciclina al día 5; sin doxiciclina el día 10; con doxiciclina el día 10. Se habían recolectado cuatro huevos por réplica, totalizando 48 huevos analizados por tratamiento en cada uno de los períodos analizados. No se encontraron diferencias significativas entre tratamientos para las variables de calidad interna del huevo (color de la yema y unidad Haugh). Para las variables de calidad de la cáscara, hubo una reducción significativa de los nivelesde amarillo con el uso de doxiciclina durante 10 días, además de una reducción del peso de la cáscara y del espesor apical y ecuatorial de la cáscara, principalmente al décimo día y con el uso de doxiciclina. Se concluye que el uso de la doxiciclina no interfiere en la calidad interna de los huevos, pero da una tonalidad grisácea a las cáscaras, y reduce su peso y grosor.(AU)

RESUMO

Abstract This paper aims to assess the area of ethnoecology within funding provided by the São Paulo Research Foundation (FAPESP) to projects and events in order to discuss the importance of this area for the conservation and sustainable use of biodiversity and the opportunity to advance this area of knowledge, The paper presents a retrospective analysis of the 75 projects and 21 events organized in the area of ethnoecology that received support from FAPESP in the last 60 years. For this purpose, a search was performed in the FAPESP databases using the keywords Ethnoecology, Ethnobiology, Ethnoscience, Ethnoichthyology, Ethnotaxonomy, Ecological Anthropology, Ethnobotany, Ethnozoology, Ethnopharmacology, Traditional Knowledge, Traditional Ecological Knowledge, Indigenous Knowledge, Ethnography, Human Ecology and Ethnoarcheology. Research Support modality accounted for most of the projects (88%), with 45.3% of funding occurring in the decade of 2000-2009. No project was supported in the first two decades and only eight were part of the BIOTA Program. The main areas of submission were Biological Sciences (46.7% of projects and 47.6% of events) and Humanities (38.7% of projects). The research questions and methods of the projects developed over the last four decades were analyzed critically and comparatively. Given the data collected, an increase of ethnocecological projects supported by the BIOTA Program and through the thematic modality may contribute to advance this area of knowledge and to cross the path from inter to transdisciplinar science.

RESUMO

O temperamento pode ser considerado a base do humor, do comportamento e da personalidade do indivíduo. Assim, o objetivo deste estudo foi verificar a influência do consumo ritual da Ayahuasca pelos adeptos daimistas do Centro Luz Divina, em relação ao temperamento de usuários experientes e iniciantes. Foi realizado um estudo transversal, do qual participaram 48 pessoas, distribuídas em dois grupos: (a) grupo estudo: subdividido em grupo experiente (16 pessoas com mais de 20 anos de uso ritual da Ayahuasca) e grupo iniciante (16 pessoas com menos de 3 anos de uso ritual); (b) grupo controle (16 pessoas que nunca utilizaram Ayahuasca), pareado por sexo, faixa etária e escolaridade. Foi utilizada a Escala Composta de Temperamento Emocional e Afetivo(AFECTS). Observou-se efeito significante entre os grupos na dimensão emocional Vontade [F(2,48)= 4,75; p=0,013],ressalte-se que o grupo experiente (47,00) obteve melhor pontuação que o grupo controle (42,68). Verificou-se o efeito da interação entre grupo e sexo na dimensão emocional Controle [F(5,48)= 7,04; p=0,002], grupo feminino experiente (46,50) versus grupo feminino controle (39,87). Considerando apenas o grupo estudo (experiente e iniciante), constatou-se: correlação positiva da dimensão emocional Vontade com Maturidade (coping) e Estabilidade; correlação positiva da dimensão emocional Controle com Maturidade (coping), Estabilidade e Cautela, e negativa com Raiva. Em conclusão, todas as mulheres do grupo experiente obtiveram classificação do temperamento “Estáveis”e atingiriam escores significativos na dimensão emocional Controle, enquanto o grupo experiente, de ambos os sexos, sobressaiu-se na dimensão emocional Vontade.(AU)


Temperament can be considered the basis of the individual’s humor, behavior and personality. The aim of this study was to verify the influence of Ayahuasca’s ritual consumption, by the daimist adepts of Centro Luz Divina, in relation to the temperament of experienced users and beginners. A cross-sectional study in which 48 people participated was performed. They were distributed into two groups of 16 people: (a) study group subdivided into an experienced group (16 people with over 20 years of Ayahuasca’s ritual use) and a beginners group (16 people with less than 3 years of ritual use); (b) control group (16 people who never used ayahuasca) paired by sex, age and scholarity. The Affective and Emotional Composite Temperament Scale (AFECTS) was applied. A significant effect was observed in the Volition dimension [F(2,48)= 4,75; p = 0,013]. The score of the experience group (47,00) was higher than the control group (42,68). It was verified the effect of the interaction between group and sex in the Control dimension [F(5,48)= 7,04; p = 0,002]: experienced female group (46,50) versuscontrol female group (39,87). Considering only the study group (both experienced and beginners) it was verified: positive correlation of the Volition dimension with Coping and Stability; positive correlation of the Control dimension with Coping, Stability and Caution, and negative correlation with Anger. In conclusion, all women in the experienced group obtained “stable” temperament rating and achieved significant scores in the emotional dimension Control; while the experienced group, of both genders, stood out in the emotional dimension Volition.(AU)

RESUMO

Leishmaniasis is a neglected tropical disease that affects people living in tropical and subtropical areas of the world. There are few therapeutic options for treating this infectious disease, and available drugs induce severe side effects in patients. Different communities have limited access to hospital facilities, as well as classical treatment of leishmaniasis; therefore, they use local natural products as alternative medicines to treat this infectious disease. The present work performed a bibliographic survey worldwide to record plants used by traditional communities to treat leishmaniasis, as well as the uses and peculiarities associated with each plant, which can guide future studies regarding the characterization of new drugs to treat leishmaniasis. A bibliographic survey performed in the PubMed and Scopus databases retrieved 294 articles related to traditional knowledge, medicinal plants and leishmaniasis; however, only 20 were selected based on the traditional use of plants to treat leishmaniasis. Considering such studies, 378 quotes referring to 292 plants (216 species and 76 genera) that have been used to treat leishmaniasis were recorded, which could be grouped into 89 different families. A broad discussion has been presented regarding the most frequent families, including Fabaceae (27 quotes), Araceae (23), Solanaceae and Asteraceae (22 each). Among the available data in the 378 quotes, it was observed that the parts of the plants most frequently used in local medicine were leaves (42.3% of recipes), applied topically (74.6%) and fresh poultices (17.2%). The contribution of Latin America to studies enrolling ethnopharmacological indications to treat leishmaniasis was evident. Of the 292 plants registered, 79 were tested against Leishmania sp. Future studies on leishmanicidal activity could be guided by the 292 plants presented in this study, mainly the five species Carica papaya L. (Caricaceae), Cedrela odorata L. (Meliaceae), Copaifera paupera (Herzog) Dwyer (Fabaceae), Musa × paradisiaca L. (Musaceae), and Nicotiana tabacum L. (Solanaceae), since they are the most frequently cited in articles and by traditional communities.

RESUMO

Objectives: The objectives of this study were (a) to describe the history of the formation of the Centro Luz Divina (CLD), Piedade, São Paulo, (b) to describe the plants and recipes involved in making ayahuasca, and (c) to provide information for future chemical and pharmacological studies of ayahuasca. Methods: During the 578 hours of fieldwork between 2017 and 2019, 10 interviewees were interviewed (two priests and eight CLD leaders). The methods and techniques from cultural anthropology were used to conduct a snowball sampling to select respondents and record data through unstructured interviews, participant observation and field diaries. Data on the history of the CLD's formation, plants and beverage recipes were recorded. The plants were dry collected and deposited at the UNIFESP Herbarium. Results: The history of the formation of the CLD, which was founded in 2002, was detailed. This center produces several recipes of the ayahuasca beverage during rituals named feitios in Portuguese by using the plants Psychotria viridis and Banisteriopsis caapi. The process of making two of these recipes was detailed in the present study, and they are the "First Degree beverage" and "Second Degree beverage", which vary in preparation time, concentration, diversity and amount of the plant used and may lead to different "potencies of the beverage", according to the interviewees' reports. From a pharmacological point of view, higher degree beverages are probably richer beverages from the chemical and pharmacological perspectives. Conclusion: Ayahuasca recipes produced at the CLD may have different "potencies". However, future chemical and pharmacological investigations should consider these and other types of ayahuasca found in other Daimist centers in their protocols since many studies suggest the use of the substances in this beverage for treating Parkinson's, anxiety, depression, and other ailments, as described in the scientific literature.

RESUMO

The Atlantic Forest is considered the fourth most important biodiversity hotspot. Although almost 96% of its original area has been devastated, a large part of its remaining conserved area is inhabited by traditional communities. This research focused on two Quilombola communities who reside within the Núcleo Picinguaba of the Serra do Mar State Park, State of São Paulo, Brazil. The objective was to use a combination of ethnoecological and ecological approaches to select priority species for which to develop participatory conservation and sustainable management plans in protected areas in Brazil. We collaborated with community members to collect ethnobotanical and ethnoecological data and then measured the abundance of native species in local forests through phytosociological sampling. We used this information to assess the degree of threat to useful species using the Conservation Priority Index, adding an additional layer of analysis based on habitat successional categories. We then overlayed those useful species identified as highest risk locally with those federally listed as threatened or endangered. Based on this, we identified three species as priority for the development of sustainable management plans: Virola bicuhyba, Cedrella fissilis and Plinia edulis.

RESUMO

INTRODUCTION: Ethnobotanical studies that include participatory methods aim to engage residents in different steps to promote the strengthening and perpetuation of local culture, and empowerment in making decisions about the use of available environmental resources. Thus, the aim of this project was to perform an ethnobotanical survey based on traditional knowledge of medicinal plants with the active participation of residents living in Bairro do Cambury, Ubatuba, São Paulo State, Brazil. MATERIALS AND METHODS: During meetings held between the researchers and community members, locally used plants were regarded as an important means for preserving local knowledge for future generations. Some residents showed interest in participating as local partners, and training courses for collecting ethnobotanical data were offered. Local partners and researchers from São Paulo Federal University (Universidade Federal de São Paulo) utilized ethnobotanical methods to select and interview the specialists in medicinal plants for 80 days between 2016 and 2018. Data on plant use were recorded, and plants were collected and deposited in two herbaria. Furthermore, participant observation and fieldwork diaries were used by the researchers, aiding the data analysis. RESULTS: Three local partners participated in objective definitions, data collection, analysis and publication. Nine local specialists were interviewed by the local partners and indicated the use of 82 plant species in 90 recipes for 55 therapeutic uses. These uses were grouped into 12 categories. In addition, a video and booklet were created. CONCLUSIONS: Data obtained during participatory research show that training local communities in the registration of their own knowledge is feasible and necessary since they register knowledge based on local perceptions, as well as valuing knowledge and approaching the current discussion about intellectual property is a global concern.
