    Notes: Summary There has been considerable interest in using safeguarded needles to reduce needlestick injury. In a randomised design, we studied the efficacy and safety of two such needles (the Insyte AutoGuard and the Protective Acuvance), by comparing them with a conventional catheter needle (Insyte), for intravenous cannulation (18 G) in 150 patients and for intra-arterial cannulation in another 150 patients (20 G). For intravenous cannulation, the success rates were similar in the three groups but insertion of the AutoGuard or Acuvance catheter was significantly more difficult than the conventional catheter. For the Acuvance, the back-flow of blood into the chamber was sometimes too slow. For intra-arterial cannulation, insertion of the AutoGuard was significantly more difficult than the other two devices, mainly because the backflow chamber of the AutoGuard was too short so that the chamber often filled with blood before cannulation. Insertion of the Acuvance was significantly more difficult than the conventional catheter. For both intravenous and intra-arterial insertion, handling of the withdrawn needle was judged significantly safer in the AutoGuard group than the other two groups, whereas there was no significant difference in the safety between the Acuvance and conventional groups. In five subjects from the AutoGuard group, blood splashed on retraction of the needle. Blood contamination during needle withdrawal occurred frequently in the control and Acuvance groups, but rarely occurred in the AutoGuard group. Therefore, the AutoGuard needle is more suitable for intravenous cannulation, and the Acuvance is more suitable for intra-arterial cannulation.

    Association of ACE I/D polymorphism with cardiovascular risk factors (2000)

    Notes: Abstract. Since the identification of an insertion/deletion (I/D) polymorphism in the angiotensin-converting enzyme (ACE) gene, the D allele has been recognized to be associated with cardiovascular disease. Moreover, significant associations of this polymorphism with multiple cardiovascular risk factors have been reported, although some studies failed to detect such associations. In the present study, we investigated the association of the ACE gene polymorphism with the parameters of multiple risk factors in 300 Japanese men who participated in a medical check-up. This investigation detected a significant association of the polymorphism with systolic blood pressure (P=0.007) and diastolic blood pressure (P=0.026), with their highest values in DD subjects and lowest values in II subjects. This significant association is consistent with the proposition that the polymorphism influences blood-pressure variability in men. Furthermore, we investigated the association of the polymorphism with four major disorders (obesity, hyperlipidemia, hypertension, diabetes mellitus) correlated with the risk for cardiovascular disease in the same 300 subjects. This investigation failed to detect any significant association of the polymorphism with each disorder. However, there was a trend that all four disorders were more frequent in ID and DD subjects than in II subjects. We therefore analyzed the association between the ACE gene polymorphism and having at least one of the four disorders in the same population. This analysis detected a significant difference: that ID and DD subjects had at least one of the four disorders more frequently than II subjects (P=0.008; odds ratio=1.89, 95% confidence interval=1.19–2.99). Taken together, the results of this study are compatible with the proposition that the ACE polymorphism is associated with cardiovascular disease partially mediated through the four disorders in our population.

    Autogenous bone marrow graft to non-ossifying fibroma with a pathologic fracture (2000)

    Notes: Abstract Non-ossifying fibroma with a pathological fracture of the radius in a 10-year-old girl was successfully treated by curettage and autogenous bone marrow graft. The lesion was completely replaced by normal bone at 1 year after the operation. Autogenous bone-marrow graft was considered to be a useful method for the treatment of non-ossifying fibroma with minimal morbidity of the graft-harvesting site.

    Notes: Abstract. Studying monogenic hereditary disorders that manifest age-related phenotypes in cells, tissues, and the total organism would be helpful for clarifying the mechanisms of aging. In this context, seven human disorders that manifest age-related phenotypes have been found to be caused by aberrations of five proteins with seven helicase motifs conserved in most of the helicases. These disorders are xeroderma pigmentosum, Cockayne syndrome, trichothiodystrophy, Bloom syndrome, Werner syndrome, X-linked α -thalassemia/mental retardation syndrome, and Juberg-Marsidi syndrome. A decline of probably pleiotropic and fundamental function of helicases in these disorders is, therefore, implied to underlie not only the various age-related phenotypes of the disorders but also the pleiotropic and universal nature of ordinary aging. Consistent with this implication, studies of these seven disorders suggest that their various age-related phenotypes are caused by aberrations in multiple processes, especially transcription. Furthermore, a few studies imply some association between aberration of the helicases and phenotypes in ordinary aging.

    Notes: Abstract Adenosine A1 receptor agonists given prior to myocardial ischemia limit ischemic injury in several species. However, the ability of adenosine receptor agonists to limit infarct size when given at reperfusion has proved controversial. We designed a three-center experimental study using a blinded, randomized treatment protocol to test the hypothesis that adenosine A1 receptor activation during early reperfusion can attenuate lethal reperfusion injury, thereby reducing infarct size. Sixty anesthetized rabbits (20 in each laboratory) underwent 30 minutes coronary artery occlusion followed by 120 minutes reperfusion. The selective adenosine A1 receptor agonist GR79236 (10.5 μg/kg, a dose shown to limit infarction in this model when given before ischemia) or vehicle were administered IV 10 minutes before reperfusion. Infarct size was assessed by tetrazolium staining and, after the randomization code was revealed, data from the three laboratories were pooled for statistical analysis. Infarct size was not modified by administration of GR79236. In the vehicle-treated group, the infarct-to-risk ratio was 28.9 ± 2.7% (n = 24) compared with 31.9 ± 2.6% (n = 26) in the GR79236-treated group (not significant). Risk zone volume was similar in the two groups (1.06 ± 0.05 cm3 vs 1.00 ± 0.05 cm3, respectively). A modest reduction in rate-pressure product was noted following the administration of GR79236, but this effect was transient. The same dose of GR79236 was found to limit infarct size when given prior to coronary artery occlusion. We conclude that A1 receptor activation does not modify lethal reperfusion injury in myocardium.
