| metaplastic breast carcinoma with epithelial phenotype of pseudosarcomatous components. | a case of metaplastic breast carcinoma was subjected to an immunohistochemical study to characterize its apparent fibrosarcomatous and chondrosarcomatous elements. polyclonal and monoclonal antibodies against epithelial cell components such as keratin proteins, epithelial membrane antigen, membrane and cytoplasmic antigens of human mammary carcinoma cells, and carcinoembryonic antigen were used, as well as antibodies against the mesenchymal antigens, desmin, and vimentin. the cells with a mesenc ... | 1988 | 3337621 |
| regulation of central cholecystokinin recognition sites by guanyl nucleotides. | guanyl nucleotides affected the binding of radiolabeled cholecystokinin (cck) octapeptide to rodent cortical binding sites. micromolar quantities of a stable gtp analogue, guanylyl-imidodiphosphate (gppnp), resulted in a plateau where binding was decreased by 30%. in the presence of 25 microm gppnp, binding analysis revealed a decrease in affinity (increase in kd), without an apparent effect on the maximal number of binding sites. ki values for cck-related peptides shifted up to 1.6-fold. the ra ... | 1988 | 3339367 |
| anterior perineal dislocation of the hip with fracture of the femoral head. a case report. | traumatic anterior perineal hip dislocation with an associated fracture of the femoral head is a rare entity. a 26-year-old man injured in a motorcycle accident was treated by closed reduction of the dislocation within three hours after admission. however, several reports of patients with anterior hip dislocation with associated femoral head fractures were treated nonoperatively and had unfavorable results when treatment failed to achieve anatomical position of the fragments. consequently, this ... | 1988 | 3342566 |
| lactic acidosis and recovery of neuronal function following cerebral hypoxia in vitro. | the rat hippocampal slice preparation was used to study the combined effects of hypoxia and lactic acidosis on neuronal function. control slices were exposed to a standard hypoxic insult while being perfused with normal artificial cerebrospinal fluid (acsf). experimental slices were perfused with acsf containing 1.0, 2.0, 10.0 or 20.0 mm lactic acid, 30 min before and during the same standard hypoxic insult. following at 30-min recovery period the ability of these slices to respond to orthodromi ... | 1988 | 3345436 |
| chemosensory anterior dorsal fin in rocklings (gaidropsarus and ciliata, teleostei, gadidae): somatotopic representation of the ramus recurrens facialis as revealed by transganglionic transport of hrp. | the anterior dorsal fin in rocklings consists of a fringe of 50-80 delicate, vibratile rays, which are densely beset with epidermal chemosensory cells. the innervation of these cells is from the dorsal branch of the recurrent facial nerve, which also innervates all other fins and the skin of the trunk. this nerve carries at least three classes of fibres: small (0.5-1.5 micron in diameter), medium (1.5-4 micron), and large (greater than 4 micron). approximately 12,000 small and weakly myelinated ... | 1988 | 3346379 |
| differences in synaptic inputs to preganglionic neurons in the dorsal and lateral band subdivisions of the cat sacral parasympathetic nucleus. | in the cat, preganglionic neurons (pgns) found in the dorsal portion of the sacral parasympathetic nucleus (dorsal band or db cells) participate in bowel control, while those found along the lateral edge (lateral band or lb cells) influence bladder function. in order to determine whether differences in the synaptic inputs exist between these two populations, hrp was applied to the sacral ventral rootlets of cats, and the s2 cord segment was prepared for sequential light and electron microscopy. ... | 1988 | 3346386 |
| corticotropin-induced changes in enzymatic activities of the post-pregnenolone steroidogenic pathway in rabbit adrenocortical cells. | in an attempt to delineate the effect of corticotropin (acth) on post-pregnenolone steroidogenesis, the activity of enzymatic systems operative in conversion of pregnenolone into glucocorticoids and androgens was studied in adrenocortical cells from control rabbits and from animals treated with acth for 12 days (acth 1-24, 200 micrograms s.c. daily). the cells from acth-treated rabbits exhibited an increased overall steroidogenic capacity and produced much more cortisol (p less than 0.0005) as w ... | 1988 | 3347065 |

| the duck hepatitis b virus dna polymerase is tightly associated with the viral core structure and unable to switch to an exogenous template. | the duck hepatitis b virus (dhbv) has a dna polymerase associated with it which uses the incomplete viral genome as endogenous template. a prerequisite for studying this polymerase is the availability of conditions to open viral cores without destroying their enzymatic activity. in this study, this was achieved by a brief treatment with low ph. dhbv dna in low-ph-treated cores was susceptible to digestion with deoxyribonuclease i and restriction enzymes, and large restriction fragments diffused ... | 1988 | 3347995 |
| susceptibilities of hong kong isolates of multiply resistant shigella spp. to 25 antimicrobial agents, including ampicillin plus sulbactam and new 4-quinolones. | seventy-two percent of 129 shigella isolates from two hong kong hospitals were shigella flexneri. twenty-six percent were s. sonnei, and there was only one isolate each of s. dysenteriae and s. boydii. ninety-six percent of the isolates were resistant to two or more antibiotics, and up to 11 resistances were seen in a single isolate. fifty-seven percent or more of these isolates were resistant to ampicillin, streptomycin, tetracycline, chloramphenicol, and sulfamethoxazole; and up to twenty-thre ... | 1988 | 3348608 |
| [amino acid composition of the lymph and blood in fever reactions of different durations]. | the amino acid composition of the thoracic duct lymph and blood following fever reactions (fr) of various duration has been studied in the experiments on rabbits. the experiments have shown that some changes in protein metabolism in fr are primarily manifested in amino acid lymph composition. irrespective of fr duration the amino acid content in the lymph almost always increases, which confirms the opinion concerning catabolic process predominance in protein metabolism during fr. the lack of "cu ... | 1988 | 3349141 |
| anti-inflammatory activity of oleoresin from brazilian copaifera. | the oleoresin from brazilian copaifera species yielded copalic acid and sesquiterpenes and showed marked anti-inflammatory activity using various experimental models in rats. the oleoresin significantly inhibited carrageenin-induced pedal edema following oral doses from 0.70 to 2.69 ml/kg, but was somewhat less effective than 50 mg/kg calcium phenylbutazone. repeated administration of the oleoresin at a dose of 1.26 ml/kg for a 6-day period reduced granuloma formation with a response comparable ... | 1988 | 3352280 |

| septal thickness in human lungs assessed by computerized interactive morphometry. | we have studied the feasibility of using interactive computerized morphometric methods for the quantitation of septal thickness in the lung with the goal of introducing objective criteria for the diagnosis and grading of pulmonary fibrosis and edema. after reviewing available methods, we have decided in favor of linear intercept measurements of septal profiles which are limited to the tissue and therefore not affected by the level of lung inflation. our method consisted in generating a graphic o ... | 1988 | 3357335 |
