  • The cyanidin 3-glucoside (C3G) extracted from pigmented rice seeds in 0.5% TFA (Trifluoro acetic acid) -95% ethanol was separated by High Performance Liquid Chromatography (HPLC). A HPLC system using a Develosil ODS-5 column and 0.1 % TFA-$H_2O$~0.1 % TFA-$CH_3CN$ gradient elution was selected for separation and quantitative determination of C3G. Regression equation obtained for the standard content of C3G pigment was as Y=21.95293$^*$X-14.726771 (r=0.99$^{**}$). Using this method, 326 domestic and introduced collections were evaluated for the C3G content. The Korean bred cultivar 'Heugjinjubyeo', showed highest C3G content (552 mg/100g seed) among the tested cultivars. Among the pigmented rice cultivars ten cultivars were selected for containing a high content of C3G. The content of C3G per 100g seeds was in high order as follows: Heugjinjubyeo (552mg)>Cheng Chang (321mg)>Kilimgeugmi (240mg)>PI160979-2 (224mg)>Hong Shei Lo (221mg)>Heugnambyeo (191 mg)>Mitak =PIl60979-1 (186mg)>Suwon425 (163mg)>Sanghaehyanghyeolla (108mg). The C3G pigment was not detected in the common white rice cultivars.

  • The present work is aimed at providing additional new pure cultures of oxalate utilizing bacteria and its preliminary characterization for further work in the field of oxalate-metabolism and taxonomic studies. The taxonomy of 14 mesophilic, aerobic oxalotrophic bacteria isolated by an enrichment culture technique from soils rhizosphers, and the juice of the petiole/stem tissue of plants was investigated. Isolates were characterized with 95 morphological, biochemical and physiological tests. Cellular lipid components and carotenoids of isolates were also studied as an aid to taxonomic characterization. All isolates were Gram-negative, oxidase and catalase positive and no growth factors were required. In addition to oxalates, some of the strains grow on methanol and/or formate. The taxonomic similarities among isolates, reference strains or previously reported oxalotrophic bacteria were analysed by using the Simple Matching (S/ sub SM/) and Jaccard (S$\_$J/) Coefficients. Clustering was performed by using the unweighted pair group method with arithmetic averages (UPGMA) algorithm. The oxalotrophic strains formed five major and two single-member clusters at the 70-86% similarity level. Based on the numerical taxonomy, isolates were separated into three phenotypic groups. Pink-pigmented strains belonged to Methylobacterium extorquens, yellow-pigmented strains were most similar to Pseudomonas sp. YOx and Xanthobacter autorophicus, and heterogeneous non-pigmented strains were closely related to genera Azospirillum, Ancylobacter, Burkholderia and Pseudomonas. New strains belonged to the genera Pseudomonas, Azospirillum and Ancylobacter that differ taxonomically from other known oxalate oxidizers were obtained. Numerical analysis indicated that some strains of the yellow-pigmented and nonpigmented clusters might represent new species.

  • The present study was designed to investigate the hypoglycemic activity and lipid metabolism of ethanol (EtOH) extract from the aleurone layer of anthocyanin-pigmented (AP) rice in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley male rats weighing 210~240 g were divided into 4 groups, normal, diabetic control, and two experimental groups, and diabetes in rats was induced by injection of STZ (45 mg/kg, body weight) into tail vein. The EtOH extract of the powdered aleurone layer of AP rice was administered orally in diabetic rats for 14 days. In order to find the hypoglycemic effects in the animal model, the body weight, plasma glucose levels, cholesterol, HDL-cholesterol, triglyceride (TG), free fatty acid (FFA), aspartate aminotransferase (AST) and alanine amino- transferase activities (ALT) were determined. Oral administration of 1.0 81kg on the EtOH extract for 14 days resulted in a significant reduction in blood glucose, ALT, TG and FFA. However, in the case of 2.0 g/kg, the hypo-glycemic effects were not considerable. This results suggest that the EtOH extract might induce hypoglycemic effects in STZ-induced diabetic rats due to some photochemical components in the aleurone layer of AP rice.

  • 흑미를 첨가한 반죽과 식빵의 품질을 조사하였다. 반죽에 흑미를 첨가함으로서 pH는 낮아졌으며 발효는 촉진되었다. 굽기 손실률은 흑미의 첨가량이 높을수록 낮았다. 흑미 첨가빵은 점착성과 탄력성은 낮았으나 부드러운 조직감이 있었으며, 관능검사 결과 흑미 5% 첨가빵은 와인빛깔로 색상에 대한 기호도가 높게 평가되었으며 대조구보다 촉촉한 느낌을 주었다. 흑미 첨가빵의 조직은 무첨가에 비하여 작은 전분입자의 수가 많으며 더욱 조밀하게 분포하였다. 이러한 경향은 흑미 첨가 비율이 높을수록 뚜렷하였다. 흑미 10% 첨가반죽에서는 렌즈형의 큰 전분입자가 변형된 형태로 관찰되었으며, 식감은 무첨가보다 쫄깃하나 다소 무거운 느낌을 주었다.

  • The content of anthocyanin, cyanidin 3-glucoside (C3G) and the peonidin 3-glucoside (P3G) from 591 rice cultivars and the antioxidative activities of MeOH extract from 8 rice cultivars were evaluated. Among them, C3G content of pigmented rice were ranged from 0 to 451.9mg in 100 g brown rice, while the P3G contents were in the range from 0 to 42.7mg in 100g brown rice. There was no correlation between C3G and P3G content. Total anthocyanin content ranged from 0 to 475.1mg in 100g brown rice. The antioxidative activity, the scavenging activity on DPPH (2,2-diphenyl-picryl-hydrazyl) radical of MeOH extracts from rice grain, were different according to cultivars. The activity of blockish purple pericarp rice cultivars was twice stronger than that of white pericarp cultivar. Especially, the antioxidative activity of Heugjinjubyeo was four times stronger than that of white pericarp cultivar. The scavenging effect on DPPH radical in rice extracts was related to the total anthocyanin contents of the extracts.

  • Pigmented villonodular synovitis (PVNS) is a slowly, progressive, proliferative disorder of synovial tissue characterized by villous or nodular changes of synovial-lined joints, bursae, and tendon sheaths and most frequently affects the large joints, with the knee and hip. A few studies have been reported that occurred PVNS in small joint, but mainly in hands. It is a very rare condition that occurs in the small joints of the forefoot. We have experienced the case, which developed in small joint of the forefoot, and performed total synovectomy. After the operation, there was no recurrence. We report a case of PVNS in forefoot with a review of the literature.

  • Pigmented villonodular synovitis (PVNS) is a rare proliferative disease involving the synovial membranes. Complete excision with a total synovectomy is important for diffuse type PVNS because of its high recurrence rate. In the ankle, complete excision of diffuse type PVNS is difficult due to the anatomical structure of the ankle joint. This paper reports the author's experience of surgical treatment with combined open and arthroscopic synovectomy. In this manner, it is expected that the complications of the open procedure and the recurrence rate of arthroscopic procedure can be reduced.

  • Most pigmented villonodular synovitis (PVNS) is occurred in knee joint and finger of hand. PVNS is rarely occurred in shoulder joint. In English and French literatures, less than 30 cases were reported. We report 3 PVNS cases with rotator cuff tears, which was treated by arthroscoic extensive synovectomy, debridement and rotator cuff repair. The PVNS with rotator cuff tear in shoulder joint was rarely reported in the Korean literature.

  • Diffuse pigmented villonodular synovitis (PVNS) involving ankle joint needs complete mass excision and total synovectomy to reduce recurrence rate, while surrounding ligaments can be easily damaged. So the concurrent ligament reconstruction should be considered for post-excisional instability in subtalar joint as well as lateral ankle joint. We describe our experience in the management of a diffuse type PVNS, invades lateral talocrural joint extended to subtalar joint and introduce a new technique of all-in-one reconstruction for anterior talofibular,calcaneofibular and cervical ligament. Our new reconstruction technique applying modified Chrisman and Snook technique is useful in stabilization for deficiencies of the ligament complexafter PVNS excisionat lateral ankle and subtalar joint.
