    Histocompatibility typing by cellular radioimmunoassay (1978)

    Notes: Abstract A quantitative cellular radioimmunoassay (CRIA) for histocompatibility typing is described. Chicken red blood cells (RBC) were incubated in microtiter plates with specific anti-MHC (B) alloantisera and the alloantibody bound measured indirectly by a second binding step with125I-labeled rabbit anti-chicken IgG. The assay is objective, highly consistent, and three to four orders of magnitude more sensitive than conventional hemagglutination assays. The new CRIA was used to detect minor subpopulations of cells in artificial cell mixtures; as few as 1% of relevant cells were easily detected. Erythrocyte chimerism was induced following the injection of B2/B2 chicken embryos with B15/B21 embryonic stem cells. Five weeks after hatching, erythrocyte chimerism was precisely quantitated by comparing the reaction of RBC from the putative chimeras with artificial cell mixtures using specific anti-B15/B21 alloantisera. The percent varied from 13–40% in 13 chimeric animals. The new CRIA was also used for the sensitive detection of tumor-specific antigens on a T-cell lymphoma. An unexpected finding was that anti-B15 alloantibody bound almost as well to B15/B21 heterozygous RBC as to B15/B15 homozygous cells, suggesting that either the concentration or the steric arrangement of B15 alloantigen at the erythrocyte surface may not conform to conventional expectations.

    MHC control of T lymphocyte-macrophage interactions (1979)

    Notes: Abstract Identity at the major histocompatibility complex (MHC) of primed T cells and macrophages was essential for the development of a T cell proliferative response to Purified Protein Derivative of tuberculin (PPD) in the presence of macrophage-associated antigen and potential allogeneic effects were eliminated by the use of one-way fetal liver chimeras as a T cell source. By contrast, such MHC restriction could not be shown for the T cell—macrophage interaction when antigen was present in soluble form. It was found that the proliferative response of primed (responder × nonresponder) F1 T cells to the Ir-gene controlled antigen, TNP-18 [Glu-Tyr-Lys (TNP) (Glu-Tyr-Ala)5], could only be restored by responder macrophages with bound antigen, while both responder and nonresponder macrophages reconstituted the response to soluble TNP-18. Supernatants from cultured responder or nonresponder macrophages could at least partially replace viable macrophages in the latter case. These results argue for two distinct antigen presentation mechanisms, depending on the physical state of the antigen rather than its chemical nature: one involves recognition of antigen in association with MHC-coded determinants and shows H-2 restriction, while the other, mediated by soluble factors and antigen, does not.

    Isolation and characterization of a virus (RL 1) infective on Rhizobium leguminosarum (1978)

    Notes: Abstract A virus (RL 1) that infects Rhizobium leguminosarum was isolated and studied. The virus has phagelike morphology; it has a hexagonal head and a long, flexible, noncontractile tail with a baseplate. The edgeto-edge diameter of head is 760 Å. The tail is 1515 Å long and 115 Å wide. RL 1 is stable at 4° C in distilled water, with only 20% loss in the titer after one month storage. It does not require any ion for stability, and is stable between pH 6.0 and 8.0. The virus is composed of two components; one is thermal sensitive and the other is relatively thermal resistant. Adsorption and ‘one step growth’ experiments under normal growth conditions showed a slow adsorption rate (0.82×10-9 cm3 min-1) followed by a 90 min latent period. The burst size was approximately 100 virus particles per cell.

    High-resolution diffuse X-ray scattering study from nearly perfect silicon single crystals (1979)

    Notes: High-resolution measurements of diffuse X-ray scattering (DXS) have been made at and above room temperature around 111, 333, 444 and 555 reciprocal lattice points (relps) using highly collimated Mo Kα1 and Cu Kα1 radiations with the specimen set in (1, -1, 1) symmetrical Bragg geometry. The distribution of DXS intensity around different relps has shown that at temperatures up to at least 573 K the contribution of thermal DXS to the observed DXS is very small. This is apparently due to the high value of the Debye temperature (640 K) of silicon. A remarkable feature of these results is that for the same value of the scattering vector |K*| the DXS intensity is different for the parallel and antiparallel orientations of K* relative to R*. The amount of anisotropy varied from sample to sample and depended on the thermal history of the specimen. This and the other features show that the observed DXS is predominantly due to point defects and their aggregates. A typical size parameter for the aggregates is 3000 to 10 000 Å.

    Notes: Bulgur of acceptable quality was prepared from two commercially available cultivars of triticale by boiling 10 min and cooking for 3 min or 10 min at 15 psi and 120°C. Moisture contents of 32-41% were needed to achieve a desirable level of gelatinization of starch. Compared to triticale whole meal, bulgur had almost similar amounts of protein, amino acids and gross energy but lower amounts of crude fat, thiamine, riboflavin, folic acid, vitamin E, calcium, iron, copper, phosphorus, manganese, zinc, potassium, sodium and magnesium.

    Notes: Prior studies and commonsense definitions of the decision-making process suggest that the ascriptive power of the commitment offense, gravity of the commitment offense, psychiatric characteristics of the offender, and the social identity given off by the offender's family would be causally related to variance in the deviance label, i.e., decisions to commit to a mental hospital rather than to a corrections institution. Case records from both settings were analyzed for traces of the decision. However, controlling for each of the alternative variables fails to eliminate the strong relationship between intensity of the offender's prior career of delinquent behavior and the formal deviance label qua type of commitment. The multivariate path model suggests that delinquency intensity and type of commitment are the two most important determinants of mental classification.

    PLASMA PROPRANOLOL CONCENTRATION IN PATIENTS WITH ANGINA AND ACUTE MYOCARDIAL INFARCTION (1976)

    Notes: 1. Plasma levels of propranolol were measured fluorometrically in patients with angina pectoris and in patients admitted to the Coronary Care Unit with acute myocardial infarction.2. In thirty patients with stable angina pectoris, plasma propranolol levels varied almost linearly with doses between 10 and 120 mg during 6-hourly chronic oral administration. Plasma levels greater than 100 ng/ml produced 70–80% reduction in the tachycardia induced by strenous exercise on a treadmill.3. In nineteen patients with acute myocardial infarction given oral propranolol, 20 mg 6-hourly, peak as well as trough plasma levels of the drug increased progressively but remained below 100 ng/ml in all except two patients during the first 24 h after their admission to the Coronary Care Unit.4. The data suggest that the use of low and fixed doses of propranolol may not produce adequate plasma levels or significant β-adrenoceptor blockade in the early stages of acute myocardial infarction in man.
