conclusions results showed that whereas knowledge by itself cannot guarantee men’s participation in prostate cancer screenings, perceived barriers can play an important role in discouraging men from cancer screening participation. therefore, designing programs to address these barriers is very important. results the most common barriers to screening for prostate cancer were a lack of knowledge ...

The pathogenesis of chronic cold agglutinin disease (CCAD) has been enigmatic. To determine if abnormal erythrocyte membrane constituents might provide the stimulus for antibody production, we compared the electrophoretic pattern of radiolabeled membrane glycoproteins of four patients with CCAD to that of normal control erythrocytes. For the CCAD erythrocytes, fluorographs revealed the appearan...

The reason for the compatibility or otherwise between two bloods was discovered by Landsteiner in I900. He found by a series of cross-testings with red corpuscles and blood sera from different individuals that all bloods could be divided into four chief groups according to the presence or absence from the corpuscles of one or other or both of two agglutinogens A and B. Two corresponding aggluti...

The lectin slide agglutination test for Neisseria gonorrhoeae has been modified and improved. Results show that wheat germ agglutinin and soybean lectin agglutinate 100% (193 of 193 tested) of clinical isolates of N. gonorrhoeae. Lectin-reactive meningococci can be readily identified by the hydrolysis of gammaglutamyl-3-naphthylamide. Branhamella catarrhalis, Neisseria lactamica, Neisseria sicc...

Virulent and avirulent strains of Aerococcus viridans (var.) homari were used to extend previous studies to determine and confirm differences between the 2 types. Virulent strains possessed polysaccharide capsules and were not agglutinated by lobster hemolymph serum; avirulent strains did not have capsules, were agglutinated by the lobster hemolymph serum, and most did not grow well in lobster ...

By WILLIAM C. BOYD AND ELIZABETH SHAPLEIGH F OR THE DIAGNOSIS of secretors amid non-secretors it is customary to use anti-A or anti-B agglutimiating sera, depending on the blood group of the person being tested. In many investigations, no attempt is made to separate the individuals of group 0 imito secretors and non-secretors, although it was shown9 that the absorbed sera of certaimi cattle, or...
