| ABSTRACT The objective of the study was to investigate the influence of anise seed (Pimpinella anisum L.) powder supplemented to the drinking water on selected blood parameters of broilers. In total, 360 one-day-old Hubbard Classic chicks were randomly divided into four groups with three replicates of 30 birds each. Anise seed powder was added at 0, 500, 750, and 1000mg/L to the drinking water offered to the C (control), T1, T2, and T3 groups respectively. The supplement was supplied for 56 days. When broilers were 28 and 56 days old, blood samples were collected (30 birds per group) by brachial vein puncture to evaluate the cellular components of blood (RBC, WBC, Hgb, HCT, H/L). The following serum biochemical parameters were evaluated: CHOL, GLU, TP,... |

| Candida-associated denture stomatitis is the most common form of oral candidal infection, with Candida albicans being the principal etiological agent. Candida adheres directly or via an intermediary layer of plaque-forming bacteria to denture acrylic. Despite antifungal therapy to treat denture stomatitis, infection is reestablished soon after the treatment ceases. In addition, many predisposing factors have been identified as important in the development of oral candidiasis, including malnourishment, common endocrine disorders, such as diabetis mellitus, antibacterial drug therapy, corticosteroids, radiotherapy and other immunocompromised conditions, such as acquired immunodeficiency syndrome (AIDS). These often results in increased tolerance to the most... |

| Leishmaniasis is a complex of diseases caused by Leishmania protozoa which treatment is restricted to a limited number of drugs that exhibit high toxicity, collateral effects and are often costly. There are a variety of tropical plants distributed in Brazil, and for many poor people the therapy for several diseases is based mainly on the use of traditional herbal remedies. In this work, the cytotoxic activity of 17 plant methanol extracts was evaluated on several Leishmania species and murine macrophages. Among them, the extract of Casearia sylvestris, Piptocarpha macropoda, Trembleya parviflora, Samanea tubulosa and Plectranthus neochilus showed a promissing leishmanicidal activity, exhibiting IC50 values below of 20 µg/mL against at least one species of... |

| Rauvolfia sellowii Müll. Arg. (Apocynaceae), a Brazilian native tree rich in indole alkaloids, is known as "pau-pra-tudo" and popularly used as hypocholesterolemic, hypoglycemic and antihypertensive. The aim of this work was to study the anatomy of the young stems and stem barks of this medicinal plant, in order to contribute to the identification of the species as a drug. The plant material was fixed and prepared according to standard microtechniques. The young stems have remaining epidermis, but a suberified peridermis is evident. The phellogen is located in the cortical region, forming suber externally. Underneath the phellogen, lies the phelloderm and collenchymatic region. In the cortex, there are numerous laticifers and some fibers. There is an... |

| The species Cordia curassavica (Boraginaceae), known popularly as "erva baleeira", is used in folk medicine for the treatment of several inflammatory processes and as a healing agent. The objective of the present study was to evaluate the antiedematogenic activity of crude dichloromethane extracts of Cordia curassavica and of the artemetin-enriched fraction. The crude extract and artemetin fraction were tested in the model of carrageenin-induced paw edema in male Swiss mice (25-30 g). The crude dichloromethane extract (300 and 1000 mg/kg, po, N = 6) showed significant antiedematogenic activity, reducing the edema by 42, 57 and 45% and 46, 62 and 69%, 3, 4 and 5 h after carrageenin administration, respectively. Indomethacin (10 mg/kg, po, N = 6) reduced the... |

| Abstract Natural products, especially phytochemicals, have been extensively studies and have exhibited important antiproliferative effects. The American native species Urera baccifera (L.) Gaudich. ex Wedd. (Urticaceae) is widely distributed in Brazil, where it is known as urtiga-vermelha or urtigão. The leaves are popularly used as anti-inflammatory, antirheumatic and in the treatment of gastric disorders. However, the antiproliferative potential of this plant against human tumor cells remain to be elucidated. In this study, we evaluated the antiproliferative effects of U. baccifera leaves extracts and fractions against a panel of human tumor cell lines in vitro besides a chemical evaluation of the most active sample by mass spectrometry (ESI-IT-MSn). The... |

| Although it is widely believed that an important function of protected areas is to conserve species that are unable to survive elsewhere, there are very few empirical studies in which a comparison is made between biodiversity of protected areas and that of the cultivated landscape surrounding them. We examined the diversity of trees, birds, and macrofungi at 58 sites in three land-use types in a tree-covered landscape in Kodagu district in the Western Ghats of India. Ten forest reserve sites in the formal protected area, and 25 sacred groves and 23 coffee plantations in the neighboring cultivated landscape were sampled. A total of 215 tree, 86 bird, and 163 macrofungus species were recorded. The forest reserve had a large number of trees that were... |

| ABSTRACT Solanum guaraniticum is a medicinal plant traditionally used to treat gastric and liver diseases. However, there is no documented evidence corroborating its safety. The present study evaluated the potential toxicity of S. guaraniticum leaf extract after acute administration in rats. Single doses of the extract (1.250, 2.500, and 5.000 mg/kg) were administered by gavage, and the rats were then monitored for 48 h and/or 14 days. Mortality, acute signs of toxicity, and general activity in the open field test were assessed as well as hematological and biochemical parameters, enzymatic activity (δ-aminolevulinate dehydratase and acetylcholinesterase), and oxidative stress parameters (lipid peroxidation level, non-protein thiol content, tissue catalase... |
