| in vitro activity of amikacin and ten other aminoglycoside antibiotics against gentamicin-resistant bacterial strains. | sixty-nine strains of gentamicin-resistant gram-negative bacilli obtained from different geographical sources were tested for susceptibility to 11 aminoglycoside antibiotics. from the results of determinations of minimal inhibitory concentrations, patterns of resistance were established for 45 strains of enterobacteriaceae and 24 strains of pseudomonas aeruginosa. overall, 81% of the strains were sensitive to amikacin and 33% of the strains were sensitive to butirosin, the next most active compo ... | 1976 | 62815 |
| biogenic amines derived from tryptophan in systemic and cutaneous scleroderma. | blood levels of serotonin (5-ht) and urinary excretion of 5-hydroxyindole-acetic acid (5-hiaa), tryptamine (t), and indole-acetic acid (iaa) were determined in 39 cases of systemic scleroderma and in 7 cases of very severe cutaneous scleroderma. the t/iaa ratio was normal and serotonin elevated in mild and rather severe acrosclerosis alike, i.e. in systemic scleroderma with pronounced vascular involvement. the t/iaa ratio was increased and serotonin normal in severe acroscleroderma, representing ... | 1999 | 84460 |
| thyrotoxicosis during pregnancy. | the diagnosis of thyrotoxicosis during pregnancy is difficult on clinical grounds only. the determination of free thyroid hormones or free thyroid hormone indices is important and is possibly supplemented by the trh stimulation test. thyrotoxicosis during pregnancy should always be treated actively. the authors recommend subtotal thyroidectomy if there are indications for surgical therapy (nodular goitre or large diffuse goitre). otherwise treatment with thyrostatic agents is used. after operati ... | 1999 | 84547 |
