Objective

We investigated the influence of β-receptor blocker metoprolol on return of spontaneous circulation (ROSC) during cardiopulmonary resuscitation (CPR) in rats with induced myocardial infarction (MI).

Methods

Male Sprague-Dawley rats were randomly divided into three groups: the sham-operated group, the MI group without metoprolol, which was fed the vehicle, and the MI+metoprolol group receiving intragastric metoprolol. Each group was further divided randomly into three subgroups, depending on the dosage of epinephrine administered during subsequent CPR applied after the induction of asphyxial cardiac arrest.

Results

The ROSC rate was significantly decreased in the low dose subgroup of MI group, unchanged in the medium dose subgroup of MI group, and significantly decreased in the high dose subgroup of MI group, compared with the same dose subgroup of sham-operated group. MI+metoprolol group had a lower ROSC rate than MI group in the medium dose subgroup, and a higher ROSC rate than MI group in the high dose subgroup. There was no difference in blood K+ values of successful rats between MI group and MI+metoprolol group. The rats with successful CPR had lower blood K+ values than rats with unsuccessful CPR in each of the three treatment groups.

Conclusions

Metoprolol administered to MI rats over a long period significantly improved ROSC rates under an appropriate dose of epinephrine during CPR. An increasing high blood K+ value would attenuate the rate of a successful CPR.  相似文献

The aim of the present investigation was to study the major chromosomal aberrations (CA) like deletion, translocation, inversion and mosaic in prostate cancer patients of Tamilnadu, Southern India. Totally 45 blood samples were collected from various hospitals in Tamilnadu, Southern India. Equal numbers of normal healthy subjects were chosen after signing a consent form. Volunteers provided blood samples (5 ml) to establish leukocyte cultures. Cytogenetic studies were performed by using Giemsaanding technique and finally the results were ensured by spectral karyotyping (SKY) technique. In the present investigation, major CA like deletion, translocation, inversion and mosaic were identifed in experimental subjects. Results showed frequent CA in chromosomes 1, 3, 5, 6, 7, 9, 13, 16, 18 and X. In comparison with experimental subjects, the control subjects exhibited very low levels of major CA (P〈0.05). In the present study, the high frequency of centromeric rearrangements indicates a potential role for mitotic irregularities associated with the centromere in prostate cancer tumorigenesis. Identification of chromosome alterations may be helpful in understanding the molecular basis of the disease in better manner.  相似文献

Two studies were undertaken to assess the value of exposing people to performance visualization in order to help them cope with communication apprehension (CA) in employment interviews. The first study, which took place in a laboratory, employed a pre/post‐test experimental design. Seniors who were preparing to enter the job market took part in mock interviews, completed a state communication apprehension (CA) measure, a trait CA measure, and a scale designed to measure negative thinking. Participants were then assigned to performance visualization, placebo, or control conditions. After exposure to the requisite treatment, they participated in another mock interview and completed the same battery of measures. The second study took place in the field. In this study, participants, who were about to undergo a screening interview for a job, completed state and trait CA measures, were exposed to performance visualization, and completed the state and trait CA measures the second time. These studies indicated that exposure to performance visualization related negatively to CA and negative thoughts, as well as positively to being offered a job. It showed no relationship to being asked back for a second interview. The implications of these findings are discussed in the conclusion of this report.  相似文献

Effectiveness of a video self-modelling (VSM) intervention was examined with primary schoolchildren who attended a full-time special education programme for pupils with social emotional and behavioural difficulties and who exhibited inappropriate behaviour during small-group reading instruction. A randomised multiple-probe baseline design was used in this study in four subjects with a follow-up phase 6 weeks after intervention. Four children aged 10 were videotaped during reading instruction to determine levels of active learning and behavioural difficulties. Intervention took place at the teacher’s desk or table 3–5 minutes immediately before the child’s designated time for reading group instruction. During intervention, the children were shown carefully selected brief segments of their own video that had been recorded during the previous session. Results indicated VSM was an effective intervention for increasing active learning responses and for reducing behavioural difficulties during reading instruction. Optimum results were maintained for more than 8 weeks after intervention. These results support VSM as an effective antecedent intervention and add to the growing body of evidence-based practices for elementary school pupils who have social emotional and mental health difficulties.  相似文献

Global DNA hypomethylation has been associated with increased risk for cancers of the colorectum, bladder, breast, head and neck, and testicular germ cells. The aim of this study was to examine whether global hypomethylation in blood leukocyte DNA is associated with the risk of hepatocellular carcinoma (HCC). A total of 315 HCC cases and 356 age-, sex- and HBsAg status-matched controls were included. Global methylation in blood leukocyte DNA was estimated by analyzing long interspersed element-1 (LINE-1) repeats using bisulfite-polymerase chain reaction (PCR) and pyrosequencing. We observed that the median methylation level in HCC cases (percentage of 5-methylcytosine (5mC)=77.7%) was significantly lower than that in controls (79.5% 5mC) (P=0.004, Wilcoxon rank-sum test). The odds ratios (ORs) of HCC for individuals in the third, second, and first (lowest) quartiles of LINE-1 methylation were 1.1 (95% confidence interval (CI) 0.7–1.8), 1.4 (95% CI 0.8–2.2), and 2.6 (95% CI 1.7–4.1) (P for trend <0.001), respectively, compared to individuals in the fourth (highest) quartile. A 1.9-fold (95% CI 1.4–2.6) increased risk of HCC was observed among individuals with LINE-1 methylation below the median compared to individuals with higher (>median) LINE-1 methylation. Our results demonstrate for the first time that individuals with global hypomethylation measured in LINE-1 repeats in blood leukocyte DNA have an increased risk for HCC. Our data provide the evidence that global hypomethylation detected in the easily obtainable DNA source of blood leukocytes may help identify individuals at risk of HCC.  相似文献

Automatic segmentation of bladder in CT images   总被引:1,自引:0,他引:1  
Segmentation of the bladder in computerized tomography (CT) images is an important step in radiation therapy planning of prostate cancer. We present a new segmentation scheme to automatically delineate the bladder contour in CT images with three major steps. First, we use the mean shift algorithm to obtain a clustered image containing the rough contour of the bladder, which is then extracted in the second step by applying a region-growing algorithm with the initial seed point selected from a line-by-line scanning process. The third step is to refine the bladder contour more accurately using the rolling-ball algorithm. These steps are then extended to segment the bladder volume in a slice-by-slice manner. The obtained results were compared to manual segmentation by radiation oncologists. The average values of sensitivity, specificity, positive predictive value, negative predictive value, and Hausdorffdistance are 86.5%, 96.3%, 90.5%, 96.5%, and 2.8 pixels, respectively. The results show that the bladder can be accurately segmented.  相似文献

The motor control of 49 unmedicated boys clinically diagnosed with ADHD, case‐matched with 49 non‐ADHD boys, was assessed while playing Crash Bandicoot I, a SonyTM Playstation platform computer video game. In Crash Bandicoot participants control the movements of a small‐animated figure through a hazardous jungle environment. Operationally defined measures of motor control were designated by (1) the stage of the game completed (ie, the number of obstacles successfully passed) before losing the figure's ‘life’, (2) the level of complexity that the stage represented and (3) the time taken to get to that point during the video game play. These measures were assessed under contrasting conditions of low or high working memory and distracter loads. Four tasks were administered (totalling 12 trials), incorporating both with and without distracter conditions. For those trials with the distracter, a segment of the television show The Simpsons was simultaneously played on a television screen adjacent to the computer game monitor. A 5‐way MANOVA revealed that ADHD boys took less time to complete their trials under the direct condition (ie, no working memory load) on Crash Bandicoot, compared to their matched non‐ADHD peers. When the task required additional working memory, however, the ADHD boys took significantly longer. Cumulative frequency plots of game performance revealed that in terms of the number of obstacles completed, the control participants successfully navigated more obstacles on the low working memory load task than the ADHD participants, but that the performance of the two groups was less distinguishable on the high working memory load task. The findings have implications for assessment and management of children with ADHD.  相似文献
