< 0.001), the tension time index (712 ± 381 versus 1333 ± 694,
p
< 0.01), and the double product (5629 ± 2574 versus 7440 ± 3294,
p
< 0.01) were significantly lower during assistance with the PACD than with the CBP. It was concluded that PACD is at least
as effective as CBP for restoring hemodynamic status during acute experimental cardiogenic shock. Moreover, the PACD unloads
the left ventricle more effectively than CBP, making it suitable for left ventricular mechanical support in cases with reversible
myocardial damage. 相似文献

Abstrakt 1. Nimmt ein Patient einen ihm von seinem (Zahn-)Arzt einger?umten Exklusiv-Termin nicht wahr, obwohl er auf dessen Eigenschaft
ausdrücklich hingewiesen wurde, so hat er dem (Zahn-)Arzt den Behandlungsausfall abzüglich eines angemessenen Eigenanteils
des (Zahn-)Arztes zu ersetzen.
2. Die Ersatzpflicht tritt auch dann ein, wenn der Patient den Termin nicht in der in dem Behandlungsvertrag vorgesehenen
Frist absagt. Eine hierfür seitens des (Zahn-)Arztes bestimmte Frist von zwei Tagen vor Behandlungsbeginn stellt sich für
den Patienten grunds?tzlich auch nicht als unangemessene Benachteiligung i.S. des § 307 BGB dar.
3. Ein Anspruch des Arztes entf?llt auch bei nur mündlicher Vereinbarung nicht unter dem Gesichtspunkt des § 4 Abs. 5b BMV-Z,
denn diese Vorschrift ist teleologisch dahin zu reduzieren, dass nur zahn?rztliche Honoraransprüche aus erfolgten Behandlungen
schriftlich vereinbart werden müssen. Soweit es jedoch um einen vertraglichen Anspruch wegen einer Leistungsst?rung geht,
vermag das Schriftformerfordernis des § 4 Abs. 5b BMV-Z grunds?tzlich nicht einzugreifen. (Leits?tze des Bearbeiters) 相似文献

Early during rat thymus ontogeny, an important proportion of thymocytes
expresses IL-2R and contains IL-2 mRNA. To investigate the role of the
IL-2-IL-2R complex in rat T cell maturation, we supplied either recombinant
rat IL-2 or blocking anti-CD25 mAb to rat fetal thymus organ cultures
(FTOC) under several experimental conditions. The IL-2 treatment initially
stimulated the growth of thymocytes and, as a result, induced T cell
differentiation, but the continuous addition of IL-2 to rat FTOC, as well
as the anti-CD25 administration, resulted in cell number decrease and
inhibition of thymocyte maturation. These results indicate that immature
rat thymocytes bear functional high- affinity IL-2R and that IL-2 promotes
T cell differentiation as a consequence of its capacity to stimulate cell
proliferation. Modifications in TCR alpha beta repertoire and increased
numbers of NKR- P1+ cells, largely NK cells, were also observed in
IL-2-treated FTOC. Furthermore, IL-2-responsiveness of different thymocyte
subsets changed throughout thymic ontogeny. Immature CD4-CD8-cells
responded to IL-2 in two stages, early in thymus development and around
birth, in correlation with the maturation of two distinct waves of thymic
cell progenitors. Mature CD8+ thymocytes maximally responded to IL-2 around
birth, supporting a role for IL-2 in the increased proliferation of mature
thymocytes observed in vivo in the perinatal period. Taken together, these
findings support a role for IL-2 in rat T cell development.

A total of 206 patients with Marfan syndrome were ascertained throughout genetic clinics in Wales and Scotland during the period 1970–1990. There were 45 deaths representing 22% of the cohort. Mean age at death was 45.3 ± 16.5 years. 50% median cumulative survival in the total cohort (n = 206) was 53 years for males and 72 years for females. Multivariate analysis confirmed severity as the best independent indicator of survival. These findings and survival curves will assist in the counselling of British families and individuals with Marfan syndrome. 相似文献

We have evaluated the fibrinogen/fibrin fragment E antigen assay as a diagnostic test in patients with clinically suspected venous thrombosis by comparing the results of this assay with venography in 272 patients. The result of the fragment E antigen assay was elevated in 79 of 80 patients with positive venograms for recent venous thrombosis (sensitivity 99%) and within the normal range in 161 of 192 patients with normal venograms (specificity 84%). The fragment E assay was also evaluated in 130 medical and surgical controls without evidence of venous thrombosis by leg scanning and the test was found to be relatively nonspecific. However, in the patient group under study, a correct clinical diagnosis of no thrombosis, based on a normal fragment E result, was made in 161 of 162 cases (negative predictive value of 99%). Therefore, a normal test result effectively excludes a diagnosis of venous thrombosis in clinically symptomatic patients. The assay, as currently performed, is technically demanding and takes 24 hr to complete. Therefore, it will have to be simplified before it can be applied to clinical practice. 相似文献

Following pretreatment with ticlopidine 250 mg bid for three days, a 40-year-old man underwent successful angioplasty and stenting of the proximal left anterior descending coronary artery and balloon dilation of the midcircumflex coronary artery without stenting. He subsequently developed acute coronary thromboses at both arterial sites and cardiogenic shock. The patient survived after an additional percutaneous coronary intervention (PCI) and intra-aortic balloon pump assistance. This was followed by peripheral arterial thrombosis requiring repeated therapeutic interventions. Laboratory tests for thrombophilia revealed the presence of a G20210A prothrombin gene mutation. Two years later the patient remained free of angina and claudication, and underwent an unremarkable maximum exercise treadmill test. This is the first reported case of acute, multiple coronary and peripheral arterial thrombosis following PCI in a patient with previously unsuspected inherited thrombophilia. Inherited thrombophilia should be considered as a possible cause of arterial thrombosis following PCI. 相似文献

Oral Diseases (2012) 19 , 46–58 Sjögren’s syndrome (SjS) is one of the most common autoimmune rheumatic diseases, clinically characterized by xerostomia and keratoconjunctivitis sicca. We investigated the following controversial topics: (i) Do we have reliable ways of assessing saliva production? (ii) How important are the quantity and quality of saliva? (iii) Are only anti‐SSA/Ro and anti‐SSB/La relevant for the diagnosis of SjS? (iv) Are the American‐European Consensus criteria (AECC) the best way to diagnose SjS? Results from literature searches suggested the following: (i) Despite the fact that numerous tests are available to assess salivation rates, direct comparisons among them are scarce with little evidence to suggest one best test. (ii) Recent developments highlight the importance of investigating the composition of saliva. However, more research is needed to standardize the methods of analysis and collection and refine the quality of the accumulating data. (iii) In addition to anti‐Ro/La autoantibodies, anti α‐fodrin IgA and anti‐MR3 autoantibodies seem to be promising diagnostic markers of SjS, but more studies are warranted to test their sensitivity and specificity. (iv) AECC are classification, not diagnostic criteria. Moreover, recent innovations have not been incorporated into these criteria. Consequently, treatment directed to patients diagnosed using the AECC might exclude a significant proportion of patients with SjS. 相似文献

Several animal studies indicate that mercury is a male reproductive toxicant, but human studies are few and contradictory. We examined semen characteristics and serum levels of reproductive hormones in relation to environmental exposure to mercury. Blood and semen samples were collected from 529 male partners of pregnant women living in Greenland, Poland and Ukraine between May 2002 and February 2004. The median concentration of the total content of mercury in whole blood was 9.2 ng ml−1 in Greenland (0.2–385.8 ng ml−1), 1.0 ng ml−1 in Poland (0.2–6.4 ng ml−1) and 1.0 ng ml−1 in Ukraine (0.2–4.9 ng ml−1). We found a significantly positive association between the blood levels of mercury and serum concentration of inhibin B in men from Greenland (β=0.074, 95% confidence interval (CI)=0.021 to 0.126) and in an analysis including men from all three regions (β=0.067, 95% CI=0.024 to 0.110). The association may be due to beneficial effects of polyunsaturated fatty acids (PUFAs), which are contained in seafood and fish. No significant association (P>0.05) was found between blood concentrations of mercury and any of the other measured semen characteristics (semen volume, total sperm count, sperm concentration, morphology and motility) and reproductive hormones (free androgen index (FAI), follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone and LH×testosterone) in any region. In conclusion, the findings do not provide evidence that environmental mercury exposure in Greenlandic and European men with median whole blood concentration up to 10 ng ml−1 has adverse effects on biomarkers of male reproductive health. 相似文献
