A simple one-step procedure for the determination of thymosin beta 4 in whole blood, various blood corpuscles, plasma and serum by reversed-phase high-performance liquid chromatography (HPLC) is described. The blood cells were isolated by a Ficoll density gradient technique. The isolated cells were lysed and deproteinized with perchloric acid in the(More)
OBJECTIVE To study the immediate effects of exogenous surfactant therapy on blood gases, lung volumes, and lung mechanics in adult rabbits with experimentally induced respiratory distress syndrome. DESIGN Prospective randomized, controlled study. SETTING Laboratory and animal facility of a large university. SUBJECTS Twelve adult New Zealand white(More)
The aim of this study was to investigate targeting of the liver metastases by directly 99mTc-labeled complete (IgG) and fragmented antibodies [F(ab')2 and Fab'] in relation to their kinetics and metabolic fate. A total of 127 patients with metastatic colorectal cancer were examined [IgG1, BW 431/26 (Behringwerke, Marburg, Germany) n = 50; F(ab')2, F023C5(More)
We measured clearance of 99mTc-labeled diethylenetriamine pentaacetic acid (99mTc-DTPA) in rabbits with experimentally increased alveolar surfactant content. In one group of animals, surfactant production was increased by treatment with ambroxol, and another group of animals was treated with tracheal instillation of natural surfactant. A group of untreated(More)
To establish testosterone-dependent growth in organ-culture, anlagen of preputial glands from normal wild-type and from androgeninsensitive mouse embryos carrying the testicular feminization mutation (Tfm) were explanted and cultured in the presence of testosterone. Within six days a size difference developed between Tfm and wild-type explants involving(More)
Surfactant replacement therapy may be a promising approach for treatment of respiratory failure caused by viral pneumonia. This study in mice demonstrates that during the development of lethal influenza A pneumonia, thorax-lung compliance (Ctl/kg) and lung volume at 5 cm H2O PEEP (V5/kg) significantly decrease (28 and 54%, respectively), whereas lung water(More)
The effect of intratracheal surfactant instillation on pulmonary function in rats withPneumocystis carinii pneumonia (PCP) was investigated. In those animals which developed PCP with severe respiratory failure after administration of cortisone acetate s. c. over 8–12 weeks, pulmonary function was improved by surfactant instillation. PaO2 values 30 min after(More)
In this study the importance of a low-weight surfactant protein (11 kDa) is demonstrated by selectively blocking this protein with a monoclonal antibody. In adult rats respiratory failure was induced by repeated bronchoalveolar lavage to remove all pulmonary surfactant. It was shown that surfactant mixed with the antibody was not capable of restoring lung(More)
The steroid sulphokinase activity in 105 000 g supernatant fractions from rat and bovine ovarian tissue has been determined by measuring the radioactivity incorporated into conjugated steroids after incubation with 14C-labelled androgens and oestrogens. The enzyme from bovine ovaries was partially characterized, changes in its activity with pH were measured(More)
The effect of intratracheal surfactant instillation on pulmonary function in rats with pneumocystis carinii pneumonia (PCP) was investigated. In these animals which developed PCP with severe respiratory failure after s.c. administration of cortisone acetate over 8-12 weeks, pulmonary function could be improved by surfactant instillation, as measured by an(More)
