| [the results of an investigation of the various factors influencing the late patency ratio of coronary bypass grafting]. | the purpose of this communication was to find out the factors influencing the late patency ratio of coronary artery bypass grafts of 42 patients in our institution. the following results were obtained: 1. the size of the measured diameters of coronary arteries and the graft flow rates were correlated well to the late patency ratio (p less than 0.05). 2. the regular physical exercise trainings were significantly important to keep patent grafts (p less than 0.01). 3. in blood serum studies, serum ... | 2009 | 2786538 |

| a fluorescence-based assay for quantitation of lymphokine-activated killer cell activity. | a fluorescence assay for the quantitation of tumor cell lysis by activated and non-activated killer (lak) cells is described. the target cells are labelled with a europium chelate (eu-diethylenetriaminopentaacetate) and after cytolysis caused by the lak cells the eu3+ complex is released into the culture supernatant. the addition of beta-naphthoyltrifluoroacetone to culture supernatant aliquots leads to the formation of a highly fluorescent chelate which can be measured with a time-resolved fluo ... | 2009 | 2785144 |
| heterochromatic modulation photometry. | heterochromatic modulation photometry is a method for obtaining equiluminance for a pair of heterochromatic lights presented in temporal alternation. a series of fixed standard luminance/test luminance ratios are presented, and at each ratio the modulation depth of the pair is reduced in tandem until the observer reports that flicker disappears. the data can be described by a luminance contrast template that appears v shaped when plotted on log-log coordinates. in the fitting of individual data, ... | 2009 | 2795287 |
| severity of precipitated opiate withdrawal predicts drug dependence by dsm-iii-r criteria. | drug diagnoses in dsm-iii-r are based on the dependence syndrome concept which hypothesizes that dependence on drugs is defined by behavioral and physiological changes but is separate from the social problems related to drug use. previous studies provide support for the dependence syndrome in drug use; however, no study has examined whether biological indications of addiction are related to the dependence syndrome. the present study tests this relationship in 52 opiate addicts who were administe ... | 2009 | 2763981 |

| [activation of the complement system in dilated cardiomyopathy]. | the levels of anaphylatoxins (c3a, c5a) in blood, components of complements c3 and c4, antibodies to cardiolipin, igg, iga, igm, ige and circulating immune complexes were measured in 21 patients with dilated and hypertrophic cardiomyopathy (dcmp and hcmp) and in 11 donors. the mean level of c3a in dcmp patients (572 +/- 55 ng/ml) was significantly higher than in hcmp patients (344 +/- 30 ng/ml) and in donors (294 +/- 43 ng/ml) (p less than 0.001). on comparison of c5a concentrations in dcmp pati ... | 2009 | 2763196 |

| 'catatonia' due to disulfiram toxicity. | in an alcoholic patient, catatonia developed while he was receiving disulfiram (antabuse). resolution of the question whether his state was classically catatonic required a detailed review of the literature on the subject. the conclusion reached is that the original definition still holds for psychiatric illness, but application of the term to neurological and metabolic states has often been based on imprecise criteria and failure to consider akinetic mutism and extrapyramidal motor disturbances ... | 2009 | 2742552 |
| [ultraviolet irradiation of the blood and hemosorption in the complex therapy of acute pancreatitis]. | pancreonecrosis and hemorrhagic form of the acute pancreatitis was treated in 76 patients by "traditional" methods which were added by uv irradiation of autoblood (in 12 patients), hemosorption (in 17 patients), uv irradiation of blood followed by hemosorption within 15-20 min (in 46 patients). positive changes of some homeostasis parameters after hemosorption following uvi of autoblood allow to consider their successive use in intensive therapy of patients with acute pancreatitis to be a perspe ... | 2009 | 2750012 |
| pancreatic cystadenoma. a clinicopathologic study. | a retrospective study of 19 patients with pancreatic cystadenoma included 15 patients with microcystic and 4 with mucinous cystadenomas. the typical clinical presentation was that of an elderly woman with an upper abdominal mass. an association with diabetes mellitus and extrapancreatic malignant disease was noted. total tumor resection provided the best chance of cure and removed the risk of compression of adjacent organs and, in mucinous cystadenomas, the risk of malignant transformation. | 2009 | 2818178 |
