Propagação vegetativa de aroeira-pimenteira (Schinus terebinthifolius Raddi)

Este trabalho foi realizado com o objetivo de avaliar os melhores métodos e épocas de realização da enxertia, sobre o pegamento de enxertos de aroeira-pimenteira (Schinus terebinthifolius Raddi). Foram conduzidos dois experimentos, instalados na Faculdade de Ciências Agronômicas, da Universidade Estadual Paulista - Câmpus de Botucatu-SP, nos períodos de 16 de dezembro de 2005 a 30 de janeiro 2006 e de 03 de junho a 17 de julho de 2006. O delineamento utilizado foi de blocos casualizados, com cinco tratamentos, três repetições cada e dez plantas por parcela. Os tratamentos foram: garfagem no topo em fenda cheia, inglês simples, inglês complicado; borbulhia em T normal e T invertido. As diferentes épocas do ano alteraram o índice de pegamento, o que restringe o período de coleta de garfos. A maior porcentagem de pegamento ocorreu no mês de dezembro, com a enxertia em fenda cheia (40%). No mês de junho, não houve pegamento significativo, mostrando então que o mês de dezembro é o mês ideal, entre os estudados, para a realização da enxertia em aroeira. As garfagens em geral foram superiores à borbulhia. Houve baixo índice de pegamento, quando não foi nulo, e, além disso, suas borbulhas não apresentaram brotos dentro de 45 dias. A maior porcentagem de plantas com brotos, aos 45 dias, foi pelo método inglês simples, com 92%.

Avaliação clínica e microbiológica do tratamento da estomatite protética com tintura de Schinus terebinthifolius Raddi (Aroeira)

Objective: To evaluate the clinical efficacy of Schinus terebinthifolius Raddi (aroeira) tincture in the treatment of denture stomatitis. Method: Eighteen removable denture wearers with clinical diagnosis of type II denture stomatts and presence of candidosis associated to the denture use, as confirmed by clinical and mycological examinations, were selected for the study. The patients were allocated to two groups: TG (test group) - treatment with Schinus terebinthifolius Raddi (aroeira) tincture; CG (control group), treatment with nystatin. All patients were instructed to clean the dentures with toothbrush and dentifrice, and then apply the product on the palatal mucosa and on denture surface 3 times a day, during 15 consecutive days, removing the denture at bedtime and keeping it in a receptacle with water. At the 15th day of use, the clinical and mycological examinations were redone to evaluate treatment efficacy. Data were analyzed statistically by Wilcoxon and Mann-Whitney tests at 5% significance level. Results: The inflammatory process and Candida spp. infect on were eliminated in 66.7% and 77.8% of the cases, respectively, in TG. In CG, elimination of the inflammatory process and fungal infect on occurred in 77.8% and 88.9% of the cases, respectively. These results were statistically significant (p=0.01). There was no statistically significant difference between the treatments (p>0.05). In all cases, fungal infect on was detected only on the denture, and C. albicans was the most prevalent microorganism, being present in 94.4% of the cases. Conclusion: The treatment with Schinus terebinthifolius Raddi (aroeira) tincture was effective in the treatment of denture stomatitis, promoting remission of the inflammatory process and Candida spp infection.

Produção de frutos e características morfofisiológicas de Schinus terebinthifolius Raddi., na região do baixo São Francisco, Brasil

Forest species with economic potential, such as aroeira (Schinus terebinthifolius Raddi.), require selection of individuals with superior characteristics for use in forest restoration projects and for establishment of commercial plantations. These plantations can contribute to the sustainability of natural populations of species in the remaining forest fragments, in areas of permanent preservation, legal reserves or other areas of ecological significance. It was evaluated the fruits' yield, morphometry and viability of seeds from 15 individuals of aroeira, collected in different fragments in the region of Lower São Francisco river, Sergipe State. The fruit yield was estimated by Fornier's intensity index, and the morphometric characteristics were obtained with a digital paquimeter and analytical balance. The viability and vigor were evaluated by germination percentage and germination speed index (GSI), under controlled conditions. The results of fruit yield were subjected to variance analysis, and the means were compared by Tukey (p <0.05). The other variables means were compared by Scott-Knott test (p<0.05). The individuals differed in Fournier's indices (indices 1, 2, 3 and 4) and in the size of fruits and seeds. The germination varied from 0 to 83% and the GSI from 0.00 to 0.98. The phenotypic differences observed among individuals for fruit yield, and morphophysiological characteristics can be used in forest restoration and establishment of provenances/progenies tests, aiming discrimination of superior material for future commercial plantations.

Mast cell concentration and skin wound contraction in rats treated with Brazilian pepper essential oil (Schinus terebinthifolius Raddi)

PURPOSE: To evaluate wound contraction and the concentration of mast cells in skin wounds treated with 5% BPT essential oil-based ointment in rats. METHODS: Twenty rats, male, of adult age, were submitted to skin surgery on the right (RA) and left antimeres (LA) of the thoracic region. They were divided into two groups: control (RA - wounds receiving daily topical application of vaseline and lanolin) and treated (LA - wounds treated daily with the topical ointment). The skin region with wounds were collected at days 4, 7, 14 and 21 after surgery. Those were fixed in 10% formaldehyde and later processed for paraffin embedding. Sections were obtained and stained by H.E for histopathology analysis. The degree of epithelial contraction was measured and mast cell concentration were also evaluated. RESULTS: The treated group showed higher mast cell concentrations (p<0.05) associated with increased contraction at day 7 and 14 respectively. CONCLUSION: Ointment containing 5% Brazilian pepper tree oil increases mast cell concentration and promotes skin wound contraction in rats.

In vitro cytotoxic activity of Brazilian Middle West plant extracts

Cytotoxic activity of eight plant extracts, native from the Mid-West of Brazil comprising Cerrado, Pantanal and semideciduous forest, was evaluated for MDA-MB-435, SF-295, and HCT-8 cancer cell strains. A single 100 µg.mL-1 dose of each extract was employed with 72 h of incubation for all tests. Doxorubicin (1 µg.mL-1) was used as the positive control and the MTT method was used to detect the activity. Cytotoxicity of distinct polarities was observed in thirty extracts (46%), from different parts of the following species: Tabebuia heptaphylla (Vell.) Toledo, Bignoniaceae, Tapirira guianensis Aubl., Anacardiaceae, Myracrodruon urundeuva Allemão, Anacardiaceae, Schinus terebinthifolius Raddi, Anacardiaceae, Gomphrena elegans Mart., Amaranthaceae, Attalea phalerata Mart. ex Spreng., Arecaceae, Eugenia uniflora L., Myrtaceae, and Annona dioica A. St.-Hil., Annonaceae. Extracts of at least two tested cell strains were considered to be highly active since their inhibition rate was over 75%.
