“…Uma das características sociológicas da aroeira é que a mesma apresenta regeneração por rebrota em vegetação secundária, com grande quantidade de plantas de todas idades, formando algumas vezes bosques quase puros (GUARIM NETO, 1986).…”

RESUMOEste estudo teve como objetivo caracterizar a estrutura paramétrica e o estoque de carbono de indivíduos dearoeira (Myracrodruon urundeuvaAll.) presente em um fragmento de floresta estacional decidual localizadoem Jataí, GO. Para avaliação do fragmento, foi realizado um censo, mensurando todos os indivíduos com cap (circunferência a 1,3 m do solo) ≥ 15,7 cm e georreferenciando-os. Após estabelecer as classes diamétricas,mensurou-se a altura total de 10 árvores por classe para o ajuste e seleção de um modelo hipsométrico e obtenção do volume, biomassae estoque de carbono. Foram identificados 1807 indivíduos distribuídos em toda a área do fragmento,os quais estão distribuídos em classes diamétricas com distribuição sigmoidal, com exceção para as árvores da primeira classe. O diâmetro médio das árvores foi de 15,5 cm. A equação hipsométrica selecionada para o povoamento foi ln (H) = 2,85102 -4,66042 dap -1 , com R 2 = 77,8% e erro padrão residual de ± 1,6 m. O volume de madeira oriundo dos indivíduos de aroeira mensurados foide 45 m³/ha, com produção de 40 t/ha de biomassa e estoque de 20 t/ha de carbono. Palavra-chave: Myracrodruon urundeuva All.; fragmento florestal; censo florestal; volume; alometria. ABSTRACTThis study aimed to characterize the parametric structure and carbon stock of individuals of aroeira (Myracrodruon urundeuva All.) present in a fragment Decidual Seasonal Forest located in Jataí, Goiás, Brazil. For evaluation of the fragment, a Forest Census was conducted, measuring up all individuals with cbh (circumference at breast height at 1.30 m) ≥ 15.7 cm. All trees measured were georeferenced. After establishing the diameter classes, measured to total height of 10 trees per class for setting and selecting a hypsometric model and obtain the volume, biomass and carbon stock. 1807 individuals were identified distributed in the area, which are divided into diameter classes with sigmoidal distribution, except for the trees of the first class. The average diameter tree was 15.5 cm. The hypsometric equation selected for the settlement was ln (H) = 2.85102 -4.66042 dap -1 with R 2 = 77.78 % and residual standard error of ± 1.6 m. The volume of wood obtained was 45 m³/ha with production of 40 t/ha of biomass and of 20 t/ha of stock carbon.

Ethanol extracts from six selected species from the Cerrado of the Central-Western region of Brazil, which are used in traditional medicine for the treatment of infectious diseases and other medical conditions, namely Erythroxylum suberosum St. Hil. (Erythroxylaceae), Hyptis crenata Pohl. ex Benth. (Lamiaceae), Roupala brasiliensis Klotz. (Proteaceae), Simarouba versicolor St. Hil. (Simaroubaceae), Guazuma ulmifolia Lam. (Sterculiaceae) and Protium heptaphyllum (Aubl.) March. (Burseraceae), as well as fractions resulting from partition of these crude extracts, were screened in vitro for their antifungal and antibacterial properties. The antimicrobial activities were assessed by the broth microdilution assay against six control fungal strains, Candida albicans, C. glabrata, C. krusei, C. parapsilosis, C. tropicalis and Cryptococcus neoformans, and five control Gram-positive and negative bacterial strains, Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus. Toxicity of the extracts and fractions against Artemia salina was also evaluated in this work. All plants investigated showed antimicrobial properties against at least one microorganism and two species were also significantly toxic to brine shrimp larvae. The results tend to support the traditional use of these plants for the treatment of respiratory and gastrointestinal disorders and/or skin diseases, opening the possibility of finding new antimicrobial agents from these natural sources. Among the species investigated, Hyptis crenata, Erythroxylum suberosum and Roupala brasiliensis were considered the most promising candidates for developing of future bioactivity-guided phytochemical investigations.

“…is a Brazilian native species; its roots are used by the local population as a tonic or stimulant in the treatment of the central nervous system debilities. Some studies also showed the aphrodisiac characteristic of this substance on male rodents [20-22]. A lyophilized extract of H. tomentosa has proven to inhibit the interaction among biomolecules and free radicals in the brain.…”

BackgroundCyclosporin A (CsA) is an immunosuppressive drug widely used in treatment of auto-immune diseases or after organ transplants. However, several side effects are commonly associated with CsA long term intake, some regarding to loss of reproductive organ function due to oxidative damage. Considering that phytotherapy is an important tool often used against oxidative stress, we would like to describe the beneficial effects of Heteropterys tomentosa intake to minimize the damage caused by CsA to the ventral prostate tissue of Wistar rats under laboratorial conditions.MethodsThirty adult Wistar rats (Rattus norvegicus albinus) were divided into: control group (water); CsA group (Cyclosporin A); Ht group (H. tomentosa infusion) and CsA + Ht group (CsA and H. tomentosa infusion). Plasmic levels of hepatotoxicity markers, triglycerides, cholesterol and glucose were quantified. The ventral prostate tissue was analyzed under light microscopy, using stereological, morphometrical and immunohistochemical techniques.ResultsH. tomentosa did not cause any alterations either of the plasmic parameters or of the ventral prostate structure. CsA caused alterations of GOT, total and indirect bilirubin, cholesterol, triglycerides and glucose levels in the plasma; CsA-treated rats showed alterations of the ventral prostate tissue. There were no alterations regarding the plasma levels of GOT, triglycerides and glucose of CsA + Ht animals. The same group also showed normalization of most of the parameters analyzed on the ventral prostate tissue when compared to the CsA group. The treatments did not alter the pattern of AR expression or the apoptotic index of the ventral prostate epithelium.ConclusionsThe results suggest a protective action of the H. tomentosa infusion against the side effects of CsA on the ventral prostate tissue, which could also be observed with plasmic biochemical parameters.
