Leucocyte Typing VII

Fourteen-year experience of human leucocyte antigen typing in cases of disputed parentage in Hong Kong.

Seventy-seven cases of disputed parentage were studied using the human leucocyte antigen system over a 14-year period in Hong Kong. Of these, 30 (39.0%) related to the amendment or verification of birth registration details, 20 (26.0%) were for divorce or affiliation proceedings, and 19 (24.7%) were related to overseas resident visa applications. An exclusion of parentage of at least one of the...

Leucocyte typing, cytokine expression, and epithelial turnover in the ileal pouch in patients with ulcerative colitis and familial adenomatous polyposis.

BACKGROUND/AIMS Conventional histopathology, leucocyte typing, cytokine mRNA expression, and crypt cell turnover were compared in ileal pouch biopsy specimens from patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP). METHODS Biopsy specimens were taken from 17 patients with UC and seven with FAP at a median interval of 19 months (range 2-120) after ileostomy closure...

Leucocyte adhesion defect-1.

Leucocyte adhesion defect (LAD) is an inherited disorder of phagocytic function. It is characterized by inability of the leucocytes, in particular neutrophilis to migrate from the blood stream towards sites of inflammation. LAD -1 is characterized by the absence of b 2 integrins (CD 11 / CD18) on leucocytes. This disorder is characterized by delayed separation of the umbilical cord, recurrent s...

Antiserum to Leucocyte Lysosomes

Antisera to rabbit polymorph granules and to rabbit erythrocytes have been prepared in guinea pigs. Both antigranule and antierythrocyte sera are hemolytic and both exhibit striking cytotoxicity on leucocytes. The sequence of toxic events, as observed by phase contrast cinemicrophotography and electron microscopy, consists of explosive granule lysis, cell swelling, cytoplasmic liquifaction, and...
