Evaluation of the mutagenicity and antimutagenicity of Ziziphus joazeiro Mart. bark in the micronucleus assay.

The aim of this study was to evaluate the mutagenicity (clastogenicity/aneugenicity) of a glycolic extract of Ziziphus joazeiro bark (GEZJ) by the micronucleus assay in mice bone marrow. Antimutagenic activity was also assessed using treatments associated with GEZJ and doxorubicin (DXR). Mice were evaluated 24-48 h after exposure to positive (N-nitroso-N-ethylurea, NEU - 50 mg.

Nongenotoxic effects and a reduction of the DXR-induced genotoxic effects of Helianthus annuus Linné (sunflower) seeds revealed by micronucleus assays in mouse bone marrow.

Background: This research evaluated the genotoxicity of oil and tincture of H. annuus L. seeds using the micronucleus assay in bone marrow of mice.

Bacteriostatic effect of copaiba oil (Copaifera officinalis) against Streptococcus mutans.

This study evaluated the inhibitory activity of copaiba oil (Copaifera officinalis against the cariogenic microorganism, Streptococcus mutans. For such purpose, a minimum inhibition concentration test of copaiba oil against S. mutans was performed, using the serial dilution in broth technique, with a negative control, a positive control (0.

Caries experience in a sample of adolescents and young adults with cleft lip and palate in Brazil.

Objective : To compare the caries experience of adolescents and young adults with cleft lip and/or palate (CL/P) with a noncleft control group. Design : Thirty CL/P subjects and 30 controls were clinically examined to obtain the decayed, missing and filled teeth (DMFT) and the decayed, missing and filled surfaces (DMFS) indices, gingival bleeding index, plaque index, and active caries lesions. Data concerning oral hygiene, access to fluoridated water, mother's education level, and family income were also collected.

Disparity between Multilocus Enzyme Electrophoresis, Microsatellite Markers and Pulsed-Field Gel Electrophoresis in epidemiological tracking of Candida albicans.

Various molecular systems are available for epidemiological, genetic, evolutionary, taxonomic and systematic studies of innumerable fungal infections, especially those caused by the opportunistic pathogen C. albicans. A total of 75 independent oral isolates were selected in order to compare Multilocus Enzyme Electrophoresis (MLEE), Electrophoretic Karyotyping (EK) and Microsatellite Markers (Simple Sequence Repeats - SSRs), in their abilities to differentiate and group C.

[Fungic microbiota of normal conjunctiva, sugar-cane and anemophilous fungi of the region of Monte Belo - Minas Gerais].

Aim: To evaluate the incidence of fungi in the ocular conjunctiva of sugar-cane cutting workers as well in a sugar-cane plantation environment.

Place: Monte Belo - MG, Eye Clinic, Laboratory of Physiology and Biology of Microorganisms of Unifenas, Alfenas - MG.

Methods: Swabs were made from the ocular conjunctiva of one hundred workers of both sexes and material was collected from leaves, stalk, and the environmental air from the sugar-cane plantation.

Cicatrizing and antimicrobial properties of an ozonised oil from sunflower seeds.

The ozonised sunflower oil, Bioperoxoil, was tested for its antimicrobial activity against some pathological strains in vitro together with its healing potential against Staphylococcus aureus in vivo. Bioperoxoil was tested against S. aureus, Pseudomonas aeroginosa, Candida albicans, S.

Use of licit and illicit drugs at the University of Alfenas.

Unlabelled: This paper reports the study of drug consumption carried out within the population of undergraduate students from 2 colleges of Alfenas, in the state of Minas Gerais state. Both licit and illicit drugs were studied, including alcohol, tobacco, marijuana, cocaine, heroin, crack, inhalants, glue, tranquilizers, stimulants, and others.

Methodology: The research included a wide bibliographical search and the application of a questionnaire to approximately 23% of the students (total of 6500 students).
