The molecular characterization of the mutations in hemophilia A patients is hampered by the large size of the factor VIII gene and the great heterogeneity of mutations. In this study, we have performed a protocol involving multiplex polymerase chain reaction in which 19 exons were amplified in four different combinations followed by nonradioactive single-strand conformational polymorphism (SSCP) to screen for mutations. Southern blotting was used to detect inversion of the factor VIII gene resulting from recombination between copies of the gene A (F8A) located in intron 22 of the factor VIII gene and two copies close telomeric region of X chromosome. Forty-two hemophilia A patients (21 with severe and 21 with mild-to-moderate disease) were studied. The inversion of factor VIII occurred in 13 of 21 patients affected by severe hemophilia A. One patient showed a large extra band in addition to the three bands observed after Southern blotting with the F8A probe. An abnormal electrophoretic pattern of SSCP was detected in 85% and 50% of the patients affected by mild-to-moderate and severe disease, respectively. Sixteen different mutations were identified. Eleven mutations were novel and comprised 9 point mutations and 2 small deletions. This study shows that the methodology used is safe and rapid and has potential for detecting almost all of the genetic defects of the studied hemophilia A patients. 相似文献

Background: Optimum pain relief following thoracotomy is essential for patient comfort and to reduce the incidence of postoperative pulmonary
complications.
Methods: A randomized clinical trial was conducted on 90 patients scheduled for pulmonary resection. The patients were randomly divided
into three groups. Group 1 received 0.125% bupivicaine with fentanyl 10μg.ml−1, Group 2 received 0.25% bupivicaine with fentanyl 10μg.ml−1 and Group 3 received only fentanyl 10μg.ml−1 in a calculated dose as a continuous thoracic epidural infusion. Adequacy of anglesia was assessed at rest and during movement
over 24 hours. Analgesic efficacy was assessed using a visual analogue score and an observer verbal ranking scale.
Results: Pain scores were significantly higher in Group 3 during the assessment period. (p<0.01) as compared to the other groups.
The use of intraoperative vasopressors was significantly higher (p<0.05) in Group 2 as compared to the other groups. No neurological
complications were encountered in any of the study groups.
Conclusion: We conclude that in the early postoperative period, the use of 0.125% bupivicaine improves fentanyl epidural analgesia in
patients undergoing lung resection. 相似文献

Objective
To evaluate the toxicity, predatory efficiency of Delonix elata (D. elata) and Mesocyclops aspericornis (M. aspericornis) against dengue vector, Aedes aegypti (Ae. aegypti).Methods
A mosquitocidal bioassay was conducted at different concentration of plant extract followed by WHO standard method. The probit analysis of each tested concentration and control were observed by using software SPSS 11 version package. The each tested concentration variable was assessed by DMRT method. The predatory efficiency of copepod was followed by Deo et al., 1988. The predator, M. aspericornis was observed for mortality, abnormalities, survival and swimming activity after 24 h treatment of plant and also predation on the mosquito larvae were observed.Results
D. elata were tested for biological activity against the larvae, and pupae of Ae. aegypti. Significant mortality effects were observed in each life stage. The percentage of mortality was 100% in first and second instars whereas 96%, 92% in third and fourth instars. Fitted probit-mortality curves for larvae indicated the median and 90% lethal concentrations of D. elata for instars 1-4 to be 4.91 (8.13), 5.16 (8.44), 5.95 (7.76) and 6.87 (11.23), respectively. The results indicate that leaf extract exhibits significant biological activity against life stages. The present study revealed that D. elata is potentially important in the control of Ae. aegypti. Similar studies were conducted for predatory efficiency of Copepod, M. aspericornis against mosquito vector Ae. Aegypti. This study reported that the predatory copepod fed on 39% and 25% in I and III instar larvae of mosquito and in combined treatment of D. elata and copepod maximum control of mosquito larval states and at 83%, 80%, 75% and 53% in I, II, III and IV instars, respectively.Conclusions
The combined action of plant extract and predatory copepod to effectively control mosquito population and reduce the dengue transmitting diseases. 相似文献10.

With increased access to HIV treatment throughout Africa, a generation of HIV positive children is now transitioning to adulthood while living with a chronic condition requiring lifelong medication, which can amplify the anxieties of adolescence. This qualitative study explored how adolescents in Tanzania with HIV experience their nascent sexuality, as part of an evaluation of a home-based care programme. We interviewed 14 adolescents aged 15–19 who had acquired HIV perinatally, 10 of their parents or other primary caregivers, and 12 volunteer home-based care providers who provided support, practical advice, and referrals to clinical services. Adolescents expressed unease about their sexuality, fearing that sex and relationships were inappropriate and hazardous, given their HIV status. They worried about having to disclose their status to partners, the risks of infecting others and for their own health. Thus, many anticipated postponing or avoiding sex indefinitely. Caregivers and home-based care providers reinforced negative views of sexual activity, partly due to prevailing misconceptions about the harmful effects of sex with HIV. The adolescents had restricted access to accurate information, appropriate guidance, or comprehensive reproductive health services and were likely to experience significant unmet need as they initiated sexual relationships. Care programmes could help to reduce this gap by facilitating open communication about sexuality between adolescents and their caregivers, providers, and HIV-positive peers. 相似文献
