Effects of Knowledge and Recognition of Alcohol Use during Pregnancy on Actual Alcohol Use during Pregnancy

PURPOSE: The purpose of this study was to explore the influence in a planned pregnancy of alcohol related family variables, knowledge and recognition of the effects of alcohol use during pregnancy on actual alcohol use during pregnancy. METHODS: The participants were 284 women who had experienced a pregnancy at some time in their lives. The data were collected from December 2011 to January 2012 and the method of data collection was self-report questionnaires. The instruments for this study were AUDIT-K, Knowledge of alcohol use during pregnancy, and Recognition of alcohol use during pregnancy. RESULTS: There were higher incidences of alcohol use during pregnancy when alcohol consumption was a problem, when there was a family member with an alcohol problem, or after having had an artificial abortion. There was no correlation in alcohol use during pregnancy with knowledge, but a correlation with recognition was found. CONCLUSION: The results of this study suggest that the main factor in alcohol use during pregnancy is recognition of the effects of alcohol use during pregnancy.

The Effect of Various Methods of Cross-linking in Type I Collagen Scaffold on Cartilage Regeneration

PURPOSE: Collagen is the principal structural biomolecule in cartilage extracellular matrix, which makes it a logical target for cartilage engineering. In this study, porous type I collagen scaffolds were cross-linked using dehydrothermal(DHT) treatment and/or 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide(EDC), in the presence and absence of chondroitin-6-sulfate(CS) for cartilage regeneration. METHODS: Cartilage defects were created in the proximal part of the ear of New Zealand rabbits. Four types of scaffolds(n=4) were inserted. The types included DHT cross-linked(Group 1), DHT and EDC cross- linked(Group 2), CS added DHT cross-linked(Group 3), and CS added DHT and EDC cross-linked(Group 4). Histomorphometric analysis and cartilage-specific gene expression of the reconstructed tissues were evaluated respectively 4, 8, and 12 weeks after implantation. RESULTS: The largest quantity of regenerated cartilage was found in DHT cross-linked groups 1 and 3 in the 8th week and then decreased in the 12th week, while calcification increased. Calcification was observed from the 8th week and the area increased in the 12th week. Group 4 was treated with EDC cross-linking and CS, and the matrix did not degrade in the 12th week. Cartilage-specific type II collagen mRNA expression increased with time in all groups. CONCLUSION: CS did not increase chondrogenesis in all groups. EDC cross-linking may prevent chondrocyte infiltration from the perichondrium into the collagen scaffold.

Development of biocompatible dressing material made of collagen and amniotic membrane and wound healing experiment in rat

<0.05). 4. Histologic examination revealed that AM protected leukocyte infiltration and epithelial migration was nearly completed at 4 weeks. Terudermis(R) group showed mild neutrophil infiltration until 2 weeks and completion of epithelization at 4 weeks. Control group showed massive leukocyte infiltration until 4 weeks. 5. Microvessels were increased sharply at 1 week and control group at 1 and 4 week showed significant differences with Terudermis(R) group of same interval(p<0.05) but no differences were found with AM group(p<0.05). CONCLUSION: EGF and EGF-R were well preserved in freeze-dried AM. AM attached to collagen acted as excellent biologic dressing which had similar effect with Terudermis(R). AM showed anti-inflammatory action and healing was completed at 4 weeks after full-thickness skin defect.
