BACKGROUND: Respiratory infection in pregnancy can cause various side effects and affect the fetus. Therefore, efforts to prevent infection during pregnancy are essential. This study investigated knowledge and compliance regarding the prevention of respiratory infection among pregnant women. METHODS: A survey was conducted on May 10, 2012 on 300 pregnant women who attended a maternity school education program in a tertiary care hospital. The responses of 259 women were collected and analyzed. RESULTS: Only 2 women (0.8%) had been educated about respiratory infection prevention methods, while 106 (40.9%) experienced respiratory infection during pregnancy. The mean score of respiratory infection prevention knowledge was 11.63 out of 15 points (percentage of correct answers: 77.5%). The mean score for compliance to respiratory infection prevention was 32.34 out of 52 points (percentage of practice: 62.19%). Knowledge and compliance were found to be positively correlated. CONCLUSION: Although many pregnant women experience respiratory infection during pregnancy, few have opportunities to be educated about prevention. Thus, the positive correlation between knowledge and compliance highlights the need for respiratory infection prevention education programs.

Prenatal development of the thoracic aorta of the human during the period ranging from gestation weeks 7 (C-R length 20mm) to 30 (C-R length 260mm) was examined by transmission electron microscopy and the following results were obtained. The early form of cuboidal or columnar endothelial cells at 7-9 weeks of gestation changed gradually to typical flat endothelial cells at 12-14 weeks of gestation. At 9 weeks of gestation, the mesenchymal cells begin to differentiate to myoblasts, which have small clusters of myofilaments with dense bodies and rough endoplasmic reticulum. And from 14 weeks the differentiating cells begin to form a parallel concentric lamellar structure. At 12th week of gestation, elastic fibers were first seen in subendothelial connective tissue and the intercellular spaces between smooth muscle cells. Elastic fibers appeared as small globular shape which composed of a central core of elastic and peripheral microfibrils. From this period the amount of elastic fibers and their aggregation increases gradually in both the subendothelial space and the intercellular spaces between smooth muscle cells. At 30th week of gestation, subendothelial elastic fibers almost completed the internal elastic lamina and also well formed elastic laminae were seen between the smooth muscle cells adjacent to endothelial cells. However, in the space between the smooth muscle cells near the adventitia the elastic lamina formation is delayed. In the adventitia elastic fiber were scanty but collagen fibers are abundant.

Epidemiological studies are important in both the prevention and treatment of mycobacterial infections. This study was initiated to establish the pulsed-field gel electrophoresis (PFGE) method, which are not yet extensively studied. The most apprpriate restriction endonucleases included Dral, AsnI, and XbaI. The optimal PFGE condition was different according to the enzymes used. Two stage PFGE was performed, in case of DraI first stage was performed with 10 seconds of initial pulse and 15 seconds of findA pulse, while the second stage was performed with 60 seconds of initial pulse and 70 seconds of final pu',se. The electrophoresis time for DraI-PFGE was 14 hours for each stage. Electrophoresis was performed for 22 hours, in case of XbaI, with 3 seconds of initial pulse and 12 seconds of final pulse. Electrophoresis was performed for 22 hours, in case of AsnI, with 5 seconds of initial pulse and 25 seconds of final pulse. In all cases the voltage of the electrophoresis was maintained constantly at 200 voltage. Standard mycobacterial strains, which included Mycobacterium bovis BCG, M. tuberculosis, and M. fortuitum, could not be differentiated by PFGE analysis. PFGE analysis was performed to differentiate 9 clinically isolated M. fortuitum strains using AsnI. All M. fortuitum strains showed different genotypes except 2 strains. Cluster analysis divided M. fortuitum strains into 2 large groups. PFGE analysis was performed to further differentiate M. fortuitum isolates using XbaI. The undifferentiated 2 M. fortuitum strains showed different PFGE patterns with Xba I. Cluster analysis of the XbaI-PFGE patterns showed more complex grouping than AsnI-PFGE patterns, which showed that XbaI-PFGE analysis was better than AsnI-PFGE in M. fortuitum genotyping. The top dissimilarity values of AsnI-PFGE and XbaI-PFGE were 0.74 and 0.75, respectively. This value was higher than that of arbitrarily primed polymerase chain reaction (AP-PCR) analysis and lower than that of restriction fragment length polymorphism (RFLP) analysis. This suggested that PFGE can be used as a supportive or alternative genotyping method to RFLP analysis.

The DNA fragment containing the phoA of Klebsiella pneumoniae was cloned into pACYC184. The size of the insert. was 4.0 kb and the restriction map showed it contained 3 Pstl sites and 4 PvuLI sites. The nucleotide sequence of the phoA region was determined, which showed strong (80%) sequence similarity with that of Escherichia coli. This suggested that these two species are phylogenetically very close to each other.

OBJECTIVE: Our purpose was to compare the expression of endothelial nitric oxide synthase in the placenta and umbilical cord of preeclamptic placenta with that of the normotensive placenta. METHOD: We compared placental endothelial nitric oxide synthase expression in preeclamptic (n=5) with in normal (n=5) pregnancies. Frozen sections of umbilical cords, chorionic plate vessels, and terminal villi were immunostained with a monoclonal endothelial nitric oxide synthase antibody. RESULTS: The age revaled no difference between control (28.1+4.2 years). and study group (26.1+4.7 years). The gestational age was statistically different between control (38.9+1.7 weeks) and study group (34.9+3.5 weeks). The neonatal body weight and placental weight were also statistically different between control (3060+528 g) and study group (2160 417 g). No difference in endothelial nitric oxide synthase immunostaining in the endothelium of the umbilical vessels and stem villous vessels was found between preeclamptic and normotensive pregnancies. In contrast, in the preeclamptic placental endothelial nitric oxide synthase immunostaining was seen in the terminal villous vessels. In the syncytiotrophoblast endothelial niric oxide synthase immunostaining appeared primary basal in location and diffuse in distribution in the preeclamptic placentas but primary apical in the normotensive placentas. CONCLUSION: Differences in endothelial nitric oxide synthase expression in terminal villous vessels and syncytiotrophblast may be a result of vascular alterations or damage that take place in the placenta in preeclampsia.
