BACKGROUND Mycobacteria, such as M. leprae and M. tuberculosis infect billions of humans. However, because of appropriate immune responses and antibiotic therapy, overt mycobacterial diseases occur far less frequently. M. avium subspecies paratuberculosis (MAP) causes Johne's disease in ruminants, an affliction evocative of inflammatory bowel disease (IBD). Several agents used to treat IBD (5-A...
from five obligate heterozygotes for type II hyperprolinemia. We also demonstrated a reduction in leukocyte AL-pyrroline-5-carboxylic acid dehydrogenase activity in three successive generations of a family. A portion of this work was presented at the Annual Meeting of The Society for Pediatric Research in Washiilgton, D. C., 3 May 1974, and at the National Meeting of The American Society for Cl...
The increased susceptibility to pyogenic infections noted in cattle with the Chediak-Higashi syndrome trait has been related to an impairment of leukocyte function at the cellular level. Investigations of the relationship of abnormal granule formation to increased susceptibility to infection, conducted with cell suspensions containing high concentrations of polymorphonuclear leukocytes, reveale...
Since B-lymphocytes are targets and a continuing habitat of Epstein-Barr virus (EBV) and the cell-mediated immune system becomes secondarily involved, one may anticipate that primary and persistent EBV infections in immunologically compromised individuals take unusual courses. Depending on the immunological defect, the clinical, hematological, and serological responses to primary EBV infections...
The effects of endotoxin administration on in vitro granulocyte function were studied in normal man. Four healthy volunteers received an intravenous injection of Pseudomonas endotoxin, 0.1 mug/kg. Endotoxemia resulted in transient neutropenia followed by a rebound neutrophilia. The nadir of the granulocyte count occurred at about 1 hr and maximal neutrophilia 2-4 hr after endotoxin administrati...
A patient with unexplained erythrocyte glutathione-S-transferase (GST) deficiency has been detected among 513 unrelated persons with hemolytic anemia. An otherwise healthy adult male, the deficient individual had a mild hemolytic anemia with splenomegaly, indirect hyperbilirubinemia, and cholelithiasis. Because he was adopted and childless, the hereditary nature of the defect could not be estab...
Background: Protective immune responses induced in the majority of people infected with Mycobacterium tuberculosis enable them to control TB infection. Objective: The aim of this study was to investigate CD56 and CD16 positive peripheral blood mononu-clear cells (PBMCs) and leukocyte subsets from multi-drug resistant pulmonary tuber-culosis (MDR-TB), and compare them with nonresistant (NR) TB p...
INTRODUCTION Current cell therapy for cartilage regeneration requires invasive procedures, periosteal coverage and scaffold use. We have developed a novel transplantation method with synovial mesenchymal stem cells (MSCs) to adhere to the cartilage defect. METHODS For ex vivo analysis in rabbits, the cartilage defect was faced upward, filled with synovial MSC suspension, and held stationary f...
