background: the health risks of crack cocaine smoking on the oral mucosa has not been widely researched and documented. objective: the purpose of this study was to analyze the proliferative activity of oral epithelial cells exposed to crack cocaine smoke using silver nucleolar organizer region (agnor) staining. methods: oral smears were collected from clinically normal-appearing buccal mucosa b...

Folate deficiency is associated with anemia, birth defects, cancer and neuropsychiatric disorders. The purpose of this study was to determine if a moderate folate deficiency during controlled changes in folate intake would affect chromosomal damage in lymphocytes and buccal cells. A study of nine healthy postmenopausal women volunteers (age 49-63 years) was carried out in a metabolic unit (base...

Total protein and deoxyribonucleic acid (DNA) were measured in small-intestinal washings from rats with normal and high rates of DNA (or cell) loss. There was a significant relationship between the loss of these two substances. Preparations of isolated viable epithelial cells contained much less protein in relation to DNA than did the intestinal washings. It was calculated that only 8 to 15% of...

Agglutination of yeast, human group A and guinea pig erythrocytes by multiple clinical isolates of E. coli, K. pneumoniae, and P. aeruginosa was investigated and correlated with hydrophobicity measurements of each bacterial strain. Hydrophobicity of the isolates, as measured by hydrophobic interaction chromatography, was similarly correlated with in vitro adherence of the microorganisms to bucc...

objective: the exfoliated human deciduous tooth (shed) contain multipotent stem cells that identified to be a population of highly proliferative and clonogenic .these cells are capable of differentiating into a variety of cell types including neural cells, adipocytes, and odontoblasts. material and methods: normal exfoliated human deciduous incisors collected from six- to nine-years-old childre...

DNA breakage detection-fluorescence in situ hybridization (DBD-FISH) is a recently developed technique that allows cell-by-cell detection and quantification of DNA breakage in the whole genome or within specific DNA sequences. The present investigation was conducted to adapt the methodology of DBD-FISH to the visualization and evaluation of DNA damage in buccal epithelial cells. DBD-FISH revea...
