Korean ginseng (Panax ginseng C. A. Meyer) is one of the most popular medicinal herbs in the world. This plant is known to have many health benefits and contain a wide variety of bioactive components. However, the knowledge on its lipid compound is still far from being fully explored. Although glycosyl inositol phosphoceramides (GIPCs) are the main sphingolipids in plant tissues, GIPCs of P. ginseng are unknown. The present study employed nanoESI-MS n , which generated characteristic fragmentation pattern that were used for the structural identification of P. ginseng GIPCs. In addition to detecting a typical mass fragmentation pattern for GIPC in positive ion mode, novel fragmentation correlating with cleavage of the last carbohydrate and fatty acyl chain of the ceramide moiety was identified. In total, 42 GIPC species were detected in P. ginseng. The major P. ginseng GIPC structure was hexose (R 1 )-hexuronic acid-inositol phosphoceramide, with three types of R 1 (amine, N-acetylamine, or hydroxyl). The most intense peak was found at m/z 1136.3 ([M+H] + ion), corresponding to a GIPC (d18:0/h16:0, R 1 = OH). Only three GIPC subtypes showed significantly different levels in five- and six-year-old P. ginseng tap roots.

In this case report, we present the radiologic and pathologic findings of atypical ductal hyperplasia (ADH) in the male breast. It is well known that a high-risk lesion such as ADH is a precursor of breast cancer in females. However, the clinical significance of these lesions in the male breast is still uncertain because male breasts mainly consist of ducts without lobule formation, unlike the female breast. To our knowledge, imaging findings of ADH in the male breast have not been reported previously, except for a few studies on the pathologic findings of these lesions. Through this paper, we would like to present the possible imaging features of this high-risk lesion in the male breast and review the related literature.

Metabolomics has been used as a powerful tool for the analysis and quality assessment of the natural product (NP)-derived medicines. It is increasingly being used in the quality control and standardization of NP-derived medicines because they are composed of hundreds of natural compounds. The most common techniques that are used in metabolomics consist of NMR, GC-MS, and LC-MS in combination with multivariate statistical analyses including principal components analysis (PCA) and partial least squares-discriminant analysis (PLS-DA). Currently, the quality control of the NP-derived medicines is usually conducted using HPLC and is specified by one or two indicators. To create a superior quality control framework and avoid adulterated drugs, it is necessary to be able to determine and establish standards based on multiple ingredients using metabolic profiling and fingerprinting. Therefore, the application of various analytical tools in the quality control of NP-derived medicines forms the major part of this review. Veregen® (Medigene AG, Planegg/Martinsried, Germany), which is the first botanical prescription drug approved by US Food and Drug Administration, is reviewed as an example that will hopefully provide future directions and perspectives on metabolomics technologies available for the quality control of NP-derived medicines.

Alcohol dependence is a serious disorder that can be related with a number of potential health-related and social consequences. Cortical thickness measurements would provide important information on the cortical structural alterations in patients with alcohol dependence. Twenty-one patients with alcohol dependence and 22 healthy comparison subjects have been recruited and underwent high-resolution brain magnetic resonance (MR) imaging and clinical assessments. T1-weighted MR images were analyzed using the cortical thickness analysis program. Significantly thinner cortical thickness in patients with alcohol dependence than healthy comparison subjects was noted in the left superior frontal cortical region, correcting for multiple comparisons and adjusting with age and hemispheric average cortical thickness. There was a significant association between thickness in the cluster of the left superior frontal cortex and the duration of alcohol use. The prefrontal cortical region may particularly be vulnerable to chronic alcohol exposure. It is also possible that the pre-existing deficit in this region may have rendered individuals more susceptible to alcohol dependence.

BACKGROUND/OBJECTIVES: Rubus Coreanus Miquel (RCM), used as a traditional Korean medicine, reduces chronic inflammatory diseases such as cancer and rheumatoid arthritis. However, its mechanism has not been elucidated. In this study, we examine the anti-inflammatory effects of RCM and their possible mechanisms using RAW 264.7 cells. MATERIALS/METHODS: Unripe RCM ethanol extract (UE), unripe RCM water extract (UH), ripe RCM ethanol extract (RE), and ripe RCM water extract (RH) were prepared. Inflammatory response was induced with LPS treatment, and expression of pro-inflammatory mediators (iNOS, COX-2, TNF-alpha, IL-1beta, and IL-6) and NO and PGE2 productions were assessed. To determine the anti-inflammatory mechanism of RCM, we measured NF-kappaB and MAPK activities. RESULTS: UE and UH treatment significantly reduced NF-kappaB activation and JNK and p38 phosphorylation and reduced transcriptional activities decreased iNOS, COX-2, and pro-inflammatory cytokines expressions, and NO and PGE2 productions. RE and RH treatments reduced IL-1beta and IL-6 expressions through suppressions of JNK and p38 phosphorylation. CONCLUSIONS: In this study, we showed that RCM had anti-inflammatory effects by suppression of pro-inflammatory mediator expressions. Especially, unripe RCM showed strong anti-inflammatory effects through suppression of NF-kappaB and MAPK activation. These findings suggest that unripe RCM might be used as a potential functional material to reduce chronic inflammatory responses.

Estimation of biological profile for skeletal remains by forensic anthropological examination would be possible based on physical anthropological studies which were statistically analyzed. However, physical anthropological studies for Korean population are not enough to establish biological profile for Korean because there is lack of documented osteological specimens in Korea. Recent study suggested that physical anthropological examination could be possible on the three dimensional data which were reconstructed from computed tomography, instead of preparing skeletal specimen by defleshing bone. One of the aim of this study is to evaluate Digital Korean database which were composed of computed tomographic images of 100 cadavers. The other is to perform statistical analysis on morphometrics for segmented atlas whether the results could be helpful to estimate sex in Korean. We measured 100 segmentation atlases (male 51, female 49) from the Digital Korean database which were under the control of Catholic Institute for Applied Anatomy, The Catholic University of Korea. Measurements of segmented atlas were carried out by using Mimics software (Simulation module, Version 13.0, Materialise NV, Belgium), and values of measurement were performed statistical analysis by IBM(R) SPSS(R) (version 20.0, Armonk, New York). Among 19 measurements, the width of atlas showed most crucial element for estimating sex, which was consistent with the result using dried bones of atlas and hit ratio of discriminant functions was 88.0%. 76.7 was the cut-off score of discriminant functions. This results showed that morphometrics for segmented atlas could be helpful in estimating sex using the Digital Korean database. In the future, we expect that the other researchers could more actively use the Digital Korean database as a good specimen for physical and forensic anthropological study.

PURPOSE: The aim of this study is to report on the results and discuss the role of free flap followed by ipsilateral vascularized fibular transposition (IVFT) for reconstruction of large bone and soft tissue defect combined with infection by open tibia fracture. MATERIALS AND METHODS: During the research period, lasting from December 2002 to June 2008 (Kyung Hee University Medical Center), data were collected from three patients who underwent IVFT after free flap. We analyzed the successiveness and persistency of the infection using free flapping, bone union, and hypertrophy between transposed fibula and tibia. RESULTS: Regarding free flap, successive results were observed in all examples. In the final follow-up results, transposed fibulas all survived, having hypertrophy similar to that of adjacent tibia. CONCLUSION: Reconstruction of tibia defect with free flap followed by IVTF is a useful and safe method for avoidance of the potential risk of infection for patients with a large tibial bone defect and soft tissue defect associated with infection.

Korean raspberry, Rubus coreanus Miquel (RCM), contains high concentrations of phenolic compounds, which prevent oxidative stress. To determine the effect of RCM on antioxidant capacity in humans, we assessed in vivo lipid oxidation and antioxidant enzyme activities from plasma in 15 healthy men. The subjects ingested 30 g of freeze-dried RCM daily for 4 weeks. Blood was taken at baseline and at the end of the study to determine blood lipid profiles, fasting plasma glucose, liver function, lipid peroxidation, and antioxidant enzyme activities. RCM supplementation had no effect on blood lipid or fasting plasma glucose concentrations but decreased alkaline phosphatase activity. RCM supplementation increased glutathione peroxidase activities (P < 0.05) but had no effect on lipid peroxidation. These results suggest that short-term RCM supplementation may offer health benefits by enhancing antioxidant capacity in a healthy population.

Rib seriation has not been used to identify individual human skeletal remains in Koreans. Accurate rib seriation is important for determining rib number and for establishing an individual's age at death. The aim of this study was to use a previously published quantitative method to correctly predict rib sequencing in Koreans. We used complete rib sets of 54 individuals and measured three variables: AFTAL (articular facet of the tubercle-toangle length), HAFL (head-to-articular facet length), and SCTCH (superior costo-transverse crest height). AFTAL and SCTCH were more useful than HAFL for predicting rib seriation, and AFTAL produced the simplest equation for determining sex. In the ranking, the cumulative percentage of AFTAL was 79% with an error of 0, and the range of seriation error was +/-4. Compared to other studies using European measures, AFTAL showed greater accuracy of rib seriation in this study of Korean ribs. In fact, both AFTAL and AFTAL with SCTCH accurately predicted rib 4 in 94% of cases. AFTAL was the most accurate, and use of both SCTCH and AFTAL yielded better results than either alone. Thus, the high accuracy and predictive ability showed that this method is useful for measuring rib seriation in Koreans.
