| computed tomographic evaluation of the breast. | experience with a dedicated breast ct scanner (general electric ct/m) using a contrast medium enhancement technique indicates that ct is superior to mammography, thermography, or physical examination for diagnosing both benign and malignant mammary disease especially in dense, thick, or fibrocystic breasts. ct is capable of diagnosing totally unsuspected early miniature carcinomas. it can identify and differentiate potential precancerous lesions from benign fibrocystic disease, and is the diagno ... | 2000 | 98990 |
| immunological purification of sea urchin egg tropomyosin. | the antiserum against lantern muscle tropomyosin of the sea urchin was prepared, and the presence of tropomyosin in the sea urchin egg was shown by immunodiffusion test between the antiserum and the egg tropomyosin fraction which was prepared according to the purification method for muscle tropomyosin. the sea urchin egg tropomyosin was isolated from the immuno-precipitate formed between the antiserum and the egg tropomyosin fraction. the subunit molecular weight of the egg tropomyosin was calcu ... | 2000 | 97282 |
| frontiers of quantitative cytochemistry: a review of recent developments and potentials. | this article attempts to describe the current state of quantitative cytochemical methods and to point out areas where, in the author's opinion, the greatest progress is either being made or can be expected. nearly 300 references to the current literature are cited. | 2000 | 94776 |
| urinary proline to hydroxyproline ratio varies with age. | urinary excretion of proline and hydroxyproline was studied in five groups of subjects, viz. controls, pituitary dwarfs, familial dwarfs, patients with fibrodysplasia ossificans progressive and patients with generalized scleroderma. the ratio pro/hyp in the urinary fraction precipitated with 5 parts of acetone (1 + 5 fraction) was close to one in children and youngsters in all the groups, while in adults it was higher than two. total pro/hyp does not give an accurate index of age. | 2000 | 92150 |
| scanning electron microscopic observations of the development of the somites and their innervation in anuran larvae. | the development of the paraxial mesoderm in tadpoles of xenopus, bufo and rana was observed with a scanning electron microscope. in addition to examination of the differentiation of the surface and the interior of the somites, some attention was also paid to the transformation of the material of the neural crests and to the innervation of the developing myotome. | 2000 | 97358 |

| differentiation of normal pressure hydrocephalus and cerebral atrophy by computed tomography and spinal infusion test. | the diagnostic value of computed tomography (ct) and spinal infusion test (sit) was investigated in 27 patients with normal pressure hydrocephalus (nph) and 35 patients with cerebral atrophy. the most consistent ct finding of nph was dilatation of the temporal horns, that of cerebral atrophy widening of the convexity sulci. however, 43% of patients with cerebral atrophy demonstrated no cortical atrophy. the sit showed an excellent relation with isotope cisternography and continuous intracranial ... | 1999 | 93629 |
| 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 |
| hyperthyroidism in juvenile diabetes mellitus. | three cases of hyperthyroidism occurring in juvenile patients with diabetes mellitus are presented. the presence of hyperthyroidism should be suspected in patients with diabetes mellitus when goiters develop and when there is unexplained weight loss, tachycardia, tremors, unexplained increases in insulin requirement, or instability of the diabetes with a tendency toward development of ketosis and/or ketoacidosis. | 1999 | 96415 |
| hurler/scheie phenotype. report of an inbred sibship with tapeto-retinal degeneration and electron-microscopie examination of the conjuctiva. | an inbred sibship with corneal opacities and deficient alpha-l-iduronidase activity showed signs of a hurler/scheie phenotype. the children were of normal intelligence. in one of the children, electron microscopy of the conjunctiva showed membrane-bound intracellular vacuoles and the electroretinogram was extinguished. the consanguinity of the parents is taken to indicate the presence of homozygosity of a mutant gene different from both the hurler and scheie mutants, thus rejecting the concept o ... | 1999 | 96404 |

| [renewal of noradrenaline in different zones of the central nervous system of inbred mice strains and their recombinants]. | a good correlation exists between the learning capacity and norepinephrine metabolism in the neocortex of c57 and balb inbred mice strains, as well as their f1 hybrids and seven recombinant inbred strains derived from their cross. the animals with a better learning performance are characterised by low levels of norepinephrine, as well as a slow metabolic rate of this neurotransmitter in the cortex. such a correlation has not been found to exist in the other cerebral regions studied. | 1999 | 96976 |
| group systems of serum proteins and erythrocyte enzymes in malignant lymphoma. | four group systems of serum proteins (hp, gc, gm, km) and five group systems of erythrocyte enzymes (ap, pgm1, gpt, ak, esd) were determined in 63 patients with malignant lymphoma. statistical analysis of the distribution of the above mentioned systems in patients and polish population samples did not reveal any significant differences, which points to the lack of any correlation between the disease and the group systems under examination. | 1999 | 85572 |
