The use of an episiotomy for vaginal delivery is a controversial topic in modern obstetrics. If one is done, however, correct technique of perineal trauma repair is important. The usual episiotomy has traditionally been closed with interrupted suture. The use of a less reactive material, e.g. polyglycolic acid (Dexon), seem to be suitable for subcutaneous skin closure and beneficial in terms of acute postpartum discomfort and healing. The comparison of healing and patient comfort parameters between interrupted and subcutis polyglycolic acid suture used for episiotomy repair after delivery was done. Patients had follow-up during hospital stay, and two months after delivery a self administered questionnaire was sent to all women who participated, enquiring about perineal pain, resumption of sexual intercourse and cosmetics of suture line. Of 52 patients who had repair with interrupted suture, 21 were lost to follow-up. Of 65 gravidas who had repair with subcutis suture, 23 were lost to follow-up. At the 3rd day postpartum examination, patients with subcutis sutures had significantly better healing. An inflammatory process was present in 2 of 52 patients with interrupted sutures comparable with 1 of 65 in the subcutis group, and a gaping wound in 0 of 52 and 1 of 65, respectively. Recovery of function, measured by resumption of sexual activity by 8 weeks, was demonstrated in 5 of 31 patients with interrupted sutures versus 24 of 42 patients who had subcutis sutures. Episiotomy repair with subcutis polyglycolic acid (Dexon) offers significant advantages over traditional interrupted suture, both in terms of wound healing and resumption of sexual activity. 相似文献

Sensitivities at 5.5 deg off-fovea from the aphakic observer superimposed on orange, purple and blue fields were obtained to estimate short-, middle- and long-wavelength cone spectra respectively. The middle-wavelength mechanism had a visible wavelength maximum resembling a nomogram plus an UV sensitivity fitting a cis-peak. The short (and, to a lesser extent, the long) wavelength cone sensitivities are higher in the UV than expected. 相似文献

We have exploited the intramolecular transposition preference of the Tn 5 in vitro transposition system to test its effectiveness as a tool for generation of nested families of deletions and inversions. A synthetic transposon was constructed containing an ori, an ampicillin resistance (Ampr) gene, a multi-cloning site (MCS) and two hyperactive end sequences. The donor DNA that adjoins the transposon contains a kanamycin resistance (Kanr) gene. Any Amprreplicating plasmid that has undergone a transposition event (Kans) will be targeted primarily to any insert in the MCS. Two different size targets were tested in the in vitro system. Synthetic transposon plasmids containing either target were incubated in the presence of purified transposase (Tnp) protein and transformed. Transposition frequencies (Ampr/Kans) for both targets were found to be 30-50%, of which >95% occur within the target sequence, in an apparently random manner. By a conservative estimate 10(5) or more deletions/inversions within a given segment of DNA can be expected from a single one-step 20 microl transposition reaction. These nested deletions can be used for structure-function analysis of proteins and for sequence analysis. The inversions provide nested sequencing templates of the opposite strand from the deletions. 相似文献

1,000 refugees living in Strasbourg have had a stoll parasitologic exam between 1986 and 1990. We have not retained results of South America and other areas of Asia subjects because of their scarce total number. Proportionally, the most numerous are the South East Asia Nationals (51.7%); followed by those from Middle East and Africa (20 and 15.5%) and more recently by those from East of Europe (5.2%). Their parasitic infestation's rate remains important (60.9%) but variable depending on their origin. Thus, people coming from Middle East and Africa are parasited mainly by protozoan, although those from South East Asia are parasited by helminths. It's interesant to notify that the prevalence of D. fragilis is ten times higher among East European people than in the common people. 相似文献

The ease of isolating mutations in zebrafish will contribute to an understanding of a variety of processes common to all vertebrates. To facilitate genetic analysis of such mutations, we have identified DNA polymorphisms closely linked to each of the 25 centromeres of zebrafish, placed centromeres on the linkage map, increased the number of mapped PCR-based markers to 652, and consolidated the number of linkage groups to the number of chromosomes. This work makes possible centromere-linkage analysis, a novel, rapid method to assign mutations to a specific linkage group using half-tetrads. 相似文献
