Serum tocopheral levels in brucellosis

The levels of various isomers of Tocopherol, a known effecter molecule influencing immune response of host to infectious agents, in sera of patients with brucellosis were measured by utilising high pressure liquid chromatographic techniques and compared with matched controls. Analysis of the results obtained revealed that in patients with brucellosis, serum levels of tocopherol were either markedly reduced or totally absent. These results suggest that the observed decrease or total lack of tocopherol in patients with brucellosis may result in an increase in the invasive disease causing ability of infecting organism, consequently promoting its survival in the host

Normal values for serum alpha-fetoprotein in a regional Arab population

By employing methodology based on enzyme linked immunosorbent assay [ELISA], normal reference values for serum alpha fetoprotein [AFP] in healthy males and non-pregnant females were determined. AFP levels in serum ranged from 0 to 11.5ng/ml for healthy males and from 0 to 12.78ng/ml for healthy non pregnant females.these values covered 95 percentile confidence limit and were similar to those reported for the population of Western Hemishere

normal range reference for peripheral blood lymphocyte subsets in regional Arab population

By utilising monoclonal antibodies, relative proportion of peripheral blood B and T lymphocytes subsets found in healthy regional Arab population were analysed and normal reference ranges within 2.5 to 97.5 percentile were established. The reference ranges for the B-lymphocytes, total T-lymphocyles [CD 3], T-helper/ind ucer cells [CD 4] and T-suppressor/ cytotoxic cells [CD 8] were 2.84 - 11.65, 64.50 - 86.87, 38.50 - 56.44 and 19.11 - 33.72 percent respectively. These values are similar to those reported for western populations
