The radial dependence of the diffuse reflectance from a turbid medium that is due to a point source is basically influenced by the absorption and reduced scattering coefficients. A system consisting of a HeNe laser source and a CCD camera is described for making remote measurements of the spatially resolved diffuse reflectance. Liquid tissue phantoms were made of Intralipid and trypan blue to v...

Observations have been reported which suggest that altered electrophoretic patterns of the serum proteins may accompany pregnancies that terminate in the birth of abnormal offspring . The teratogenic disazo dye, trypan blue, has been shown to cause alterations in the proteins of the maternal serum of pregnant rabbits and in the protein composition of the 9-day rabbit embryo yolk sac fluid (1,2,...

1. The time interval between radiation and the occurrence of epilation is shorter in mice injected with trypan blue than in normal animals. 2. An x-ray unit defined as that causing total spontaneous epilation on the skin of the mouse is suggested. It corresponds to four to five human erythema doses.

Trypan blue injected into an area of cutaneous inflammation induced by Staphylococcus aureus failed to drain readily to the tributary lymphatics when the dye was injected as early as 1 hour after the inoculation of the microorganisms. Trypan blue introduced into an area of cutaneous inflammation induced by Pneumococcus Type I was retained in situ when the dye was injected about 6 or more hours ...

AIM To evaluate and observe the cellular reactions that occur during the interaction/integration between 2-hydroxyethyl methacrylate/host tissue/microbial environment, in a co-culture of human gingival fibroblasts (HGF) and Streptococcus mitis strains. METHODOLOGY Streptococcus mitis were cultured with strains in the presence of 3 mmol L(-1) HEMA for 48 h and 72 h. Cytotoxicity was evaluated ...

PURPOSE To determine the potential risk of contamination of a trypan blue bottle (TB) after first use and after being stored under different temperature and humidity conditions, as well as to identify possible contamination factors, most frequently involved microorganisms and simultaneously evaluate bacteriostatic and bactericide properties of the dye. METHODS An experimental and prospective ...
