The effect of drilling speed and the chip load on the hole quality in a printed circuit board was investigated. The hole defects considered were smear, burr, nail heading and void. Holes drilled with different combinations of the speed and chip load

Sprague-Dawley rats which produce "naturally occurring" antibodies to glycerol teichoic acid (GTA) displayed immunosuppression of anti-sheep erythrocyte plaque-forming cell and serum antibody responses when a single dose of lipid-free GTA was adminis

A gentle technique for preparing spheroplasts of Capnocytophaga ochracea strain 25 is described. Cells in the exponential phase were washed with 1.0 M-NaCl, agitated in 1.0 M-NaCl for 2 h at 30 degrees C and exposed to lysozyme in a Tris/salts buffer

In an effort to determine the origin of natural antibodies to teichoic acid, rats were fed a sterile liquid diet free of detectable teichoic acid and virtually free of gram-positive bacteria. Both germ-free and conventional Sprague-Dawley rats raised

The purpose of this study was to evaluate lymphocyte subset densities and distributions within gingival biopsies from active sites (greater than or equal to 2 mm clinical attachment loss within three months of biopsy) versus clinically similar but st

Exopolysaccharide (EP) purified from spent culture fluid of three Capnocytophaga species was examined for its ability to activate the human complement system. Heparinized plasma was absorbed with bacterial cells to remove natural antibody. Aliquots o

The mechanism of immunosuppression produced by an extracellular polysaccharide (EP) from Capnocytophaga ochracea strain 25 (Socransky) was evaluated in vitro. Adherent (A), nonadherent (NA), and whole spleen cells (WS) from C57BL/6 inbred mice were p

Normal adult Sprague-Dawley rats were bled serially over a 30-week period and their sera were examined for antibodies to polyglycerophosphate (PGP) by a standardized passive hemolysis test. Levels of "natural" antibodies to PGP fluctuated during this

Naturally occurring cellular and humoral immunity to a purified polyglycerophosphate (teichoic acid) have been observed in normal albino rats. Skin tests as well as in vitro correlates of delayed hypersensitivity yielded positive results in more than
