Cell-mediated cytotoxicity for melanoma tumor cells: detection by a (3H) proline release assay

An in vitro lymphocyte-mediated cytotoxicity assay using [3H]proline-labeled target cells is described. The assay, modified from an original procedure of Bean et al., assesses the release of [3-H]proline by filtering the total culture fluid containing both trypsinized tumor cells and effector cells. Filtration is performed with a semiautomatic harvesting device using low suction pressure and large-diameter glass filters. Pretreatment of filters with whole serum diminishes adsorption of cell-free radioactive material considerably and thus increases the sensitivity of the assay. Nearly 100% of the radioactivity could be recovered with this harvesting device. The technique allowed the detection of cytolytic activities of lymphocytes after 6 h of incubation. Lymphocytes from patients with primary malignant melanoma showed a significantly higher cytolytic reactivity (P less than 0.001) than normal donors' lymphocytes against three different melanoma cell lines. In a series of parallel experiments on 36 patients and 18 normal donors, this modification of the [3H]proline test was compared with three different assays: the conventional microcytotoxicity test of Takasugi and Klein, the original [3H]proline microcytotoxicity test of Bean et al., and the viability count of tumor cells.

Acute in vivo studies of the Pittsburgh intravenous membrane oxygenator

The efficacy of an innovative intravenous membrane oxygenator (IMO) was tested acutely (6-8 hrs) in seven calves. The IMO prototypes consisted of a central polyurethane balloon within a bundle of hollow fibers with a membrane surface area of 0.14 m2. The IMO devices were inserted through the external jugular vein into the inferior vena cava of anesthetized calves (68.9 +/- 2.3 kg). Rhythmic balloon pulsation (60-120 bpm) was controlled with an intra-aortic balloon pump console. Oxygen sweep gas was delivered through the device at 3.0 L/min. Gas concentrations were monitored continuously by mass spectroscopy. The principal results were as follows: 1) oxygen and carbon dioxide exchange ranged from 125 to 150 ml/min/m2 and 150 to 200 ml/min/m2, respectively; 2) there was at least a 30-50% augmentation of gas exchange with balloon pulsation; 3) maximum exchange occurred with 60-90 bpm balloon pulsations; and 4) hemodynamic parameters remained unchanged. There were no device related complications, and the feasibility of insertion of the device by a cervical cut-down was established. These acute in vivo experiments show that the Pittsburgh IMO device can exchange oxygen and carbon dioxide gases in vivo at levels consistent with this current prototype design, and that intravenous balloon pulsation significantly enhances gas exchange without causing any end-organ damage.

Interaction of soluble C3 fragments with guinea pig lymphocytes. Comparison of effects of C3a, C3b, C3c, and C3d on lymphokine production and lymphocyte proliferation

C3a, C3b, C3c, and C3d were generated from purified guinea pig C3 by trypsin treatment. These fragments were characterized immunochemically and functionally by rosette inhibition. C3b is capable of binding to both C3b and C3d receptors on lymphocytes whereas C3d binds only to C3D receptors. C3b stimulates guinea pig spleen cells to elaborate a macrophage chemotactic factor which is similar in m.w. to that generated in response to PHA or LPS and is antigenically unrelated to C3 or C5. In contrast, neither C3a, C3c, or C3d stimulate guinea pig lymphocytes. Neither C3 nor any of its major fragments induce cellular proliferation. These data are compatible with the hypothesis that C3b triggers spleen cells to release a macrophage chemotactic factor by cross-linking C3b and C3d receptors.     

Hydrothermal Synthesis and Characterization of Pyrochlore Titanate R2Ti2O7(R=Gd3+, Tb3+, Dy3+)

Pyrochlore titanate oxides, R2Ti2O7(R=Gd3+, Tb3+, Dy3+), were synthesized under mild hydrothermal conditions. The crystal growth of pyrochlore titanate oxides and taking place of chemical reaction in the hydrothermal processing were sensitive to the alkalinity, temperature, reaction time, the nature of the rare earth ion and the composition of initial reaction mixture. The as-prepared samples were characterized by powder X-ray diffraction, scanning electron microscopy, Raman spectrum and variable temperature dc magnetic susceptibility(Superconductivity quantum interference device, SQUIDS). The magnetic studies gave 7.29×10-23 A·m2/Gd3+ and -8.28 K, 8.75×10-23 A·m2/Tb3+ and -19.7 K, and 8.85×10-23 A·m2/Dy3+ and 0.84 K effective moments and Weiss constants for Gd2Ti2O7,Tb2Ti2O7 and Dy2Ti2O7, respectively.
