    Plants Used as Natural Dye Sources in Turkey
    (New York Botanical Garden Press, 2003) Doǧan Y.; Başlar S.; Mert H.H.; Ay G.
    This study was carried out in the regions where handcrafts such as carpet and rug weaving are common in Turkey. In the regions where natural dyes are used, 123 plant species belonging to 50 families were identified as sources of natural dyes. In natural dye production, different parts of the plant or the whole aboveground plant is used. Ten different colors are gained from the plants. Sometimes the same color can be obtained from different plants. By mixing different plants, it is possible to produce various colors. We also identified more than 12 natural and more than eight chemical assistant substances (mordant) that are used in the regions to bind dye to fibers, to maintain the strongness and brightness of the colors, and to obtain various colors.

    Background: The aim of the study was to evaluate familial Mediterranean fever (FMF) mutation analysis in pediatric patients with inflammatory bowel disease (IBD). The relation between MEFV mutations and chronic inflammatory diseases has been reported previously. Methods: Children with IBD (334 ulcerative colitis (UC), 224 Crohn's disease (CD), 39 indeterminate colitis (IC)) were tested for FMF mutations in this multicenter study. The distribution of mutations according to disease type, histopathological findings, and disease activity indexes was determined. Results: A total of 597 children (mean age: 10.8 ± 4.6 years, M/F: 1.05) with IBD were included in the study. In this study, 41.9% of the patients had FMF mutations. E148Q was the most common mutation in UC and CD, and M694V in IC (30.5%, 34.5%, 47.1%, respectively). There was a significant difference in terms of endoscopic and histopathological findings according to mutation types (homozygous/ heterozygous) in patients with UC (P < .05). There was a statistically significant difference between colonoscopy findings in patients with or without mutations (P = .031, P = .045, respectively). The patients with UC who had mutations had lower Pediatric Ulcerative Colitis Activity Index (PUCAI) scores than the patients without mutations (P = .007). Conclusion: Although FMF mutations are unrelated to CD patients, but observed in UC patients with low PUCAI scores, it was established that mutations do not have a high impact on inflammatory response and clinical outcome of the disease.
