BACKGROUND: In the life cycle, bone mineral density (BMD) is the most optimal condition in the 20s. In Korea, vitamin D deficiency status is very serious in Korean women due to recent lack of activity, weight polarization, and inadequate nutritional intake. The purpose of this study was to compare serum vitamin D and BMD according to obesity status in Korean young adult women. METHODS: A total of 143 female college students participated in the research. Body fat and lean body status were analyzed using a body composition analyzer. Nutrient intakes of the subjects were assessed by 3-days food record method. The BMDs was measured by dual energy X-ray absorptiometry. The subjects were divided into normal weight group and obesity group on their body mass index. RESULTS: Obesity group showed significantly higher weight, body fat (%), and body fat (kg) than normal weight group and T-scores of lumbar-2 spines were significantly lower. Obesity group showed high triglyceride and low-density lipoprotein cholesterol levels and vitamin D levels were significantly lower. Physical fitness and activity status showed that sit and reach and sit up were significantly lower in obesity group. The intake of carbohydrates was higher in the obesity group than in the normal weight group, and the intake of vitamin C and vitamin D was significantly lower. Factors affecting serum vitamin D were analyzed as body fat (%), lumbar-2 T-score, triglyceride, and carbohydrate intake. CONCLUSIONS: Obese women need more effort to manage their serum vitamin D status and balanced nutrition to prevent bone loss.

In this study, the skeletal abnormalities associated with scurvy in subadults crania from three archaeological skeletal collections (Nukdo, Imdang, Yeanri), South Korea was analyzed to examine the prevalence and distribution of childhood scurvy of ancient Korea. For this, 30 subadults crania from the Nukdo, Imdang, Yeanri site were examined. Using criteria described by Ortner and Ericksen (1997) for identifying scurvy in skeletal material we evaluated the cranial skeleton of the subadults for evidence of abnormal porosity. All skeletal materials were macroscopically evaluated for pathological changes associated with scurvy. In results, lesions indicative of probable scurvy were observed in 22 individuals of 30 individuals. Based on the results, childhood disease relating to nutrition and metabolism in ancient Korea might have been widespread, along with scurvy. The results of the present study will be useful for understanding the health condition of the ancient Korean populations. Future work will add significantly to the larger picture of diet and disease within populations of ancient Korea.

This article demonstrates the medicinal usage of ginseng in the West from 1660 to 1914. Asian[Korea] ginseng was first introduced into England in the early 17th century, and North American ginseng was found in the early 18th century. Starting from the late 17th century doctors prescribed ginseng to cure many different kinds of ailments and disease such as: fatigue general lethargy, fever, torpidity, trembling in the joints, nervous disorder, laughing and crying hysteria, scurvy, spermatic vessel infection, jaundice, leprosy, dry gripes and constipation, strangury, yellow fever, dysentery, infertility and addictions of alcohol, opium and tobacco, etc. In the mid-18th century Materia Medica began to specify medicinal properties of ginseng and the patent medicines containing ginseng were widely circulated. However, starting in the late 18th century the medicinal properties of ginseng began to be disparaged and major pharmacopoeias removed ginseng from their contents. The reform of the pharmacopoeia, influenced by Linnaeus in botany and Lavoisier in chemistry, introduced nomenclature that emphasized identifying ingredients and active constituents. Western medicine at this period, however, failed to identify and to extract the active constituents of ginseng. Apart from the technical underdevelopment of the period, the medical discourses reveal that the so-called chemical experiment of ginseng were conducted with unqualified materials and without proper differentiation of various species of ginseng.

OBJECTIVES: Reduced bone quality caused by vitamin C deficiency in older persons may lead to incidental fragility fractures during bisphosphonate treatment, although bisphosphonate increases bone mineral density (BMD). This study aimed to evaluate the effects of minodronate and ascorbic acid (Aa) on BMD, bone quality, and bone strength in Aa(-)deficient osteogenic disorder Shionogi (ODS) rats. METHODS: Six-month-old ODS rats were divided into four groups (n = 20 per group): (1) Aa supplementation (Aa(+)); (2) Aa(-)deficient (Aa(-)); (3) Aa supplementation and minodronate administration (Aa(+) + Mino); and (4) Aa(-)deficient and minodronate administration (Aa(-) + Mino). BMD, bone strength, bone histomorphometry, and bone quality determined using Fourier transform infrared spectroscopy imaging (FTIRI) were evaluated after 4 and 8 weeks. RESULTS: BMD was significantly higher in the Aa(+) + Mino group than in the Aa(-) group (p < 0.05). Bone strength was significantly higher in the Aa(+) and Aa(+) + Mino groups than in the Aa(-) group (p < 0.05). Furthermore, bone strength was significantly higher in the Aa(+) + Mino group than in the Aa(-) + Mino group (p < 0.05). Minodronate treatment irrespective of Aa supplementation significantly decreased bone resorption compared with the Aa(+) and Aa(-) groups (p < 0.05). No significant differences in the parameters evaluated by FTIRI were observed between the groups. CONCLUSIONS: Aa supplementation improved bone strength in ODS rats. Combined treatment with minodronate and Aa, but not minodronate alone, improved bone strength and increased BMD. Aa is required for bone health because it is essential for osteoblast differentiation.

Vitamins are essential micronutrients for maintenance of tissue functions. Vitamin deficiency is one of the most serious and common health problems among both chronic alcoholics and the homeless. However, the vitamin-level statuses of such people have been little studied. We evaluated the actual vitamin statuses of alcoholic homeless patients who visited an emergency department (ED). In this study the blood levels of vitamins B1, B12, B6, and C of 217 alcoholic homeless patients were evaluated retrospectively in a single urban teaching hospital ED. Vitamin C deficiency was observed in 84.3% of the patients. The vitamin B1, B12, and B6 deficiency rates, meanwhile, were 2.3%, 2.3%, and 23.5%, respectively. Comparing the admitted patients with those who were discharged, only the vitamin C level was lower. (P=0.003) In fact, the patients' vitamin C levels were markedly diminished, vitamin C replacement therapy for homeless patients should be considered in EDs.

PURPOSE: The burn increase the requirement for the antioxidative vitamin C and decrease the plasma concentration of vitamin D due to the loss of skin body surface area. We investigated the vitamin C and D status and the prevalence of vitamin C and D insufficiency in adult burn patients undergoing rehabilitative therapy. METHODS: 256 burn patients admitted to the department of rehabilitation medicine from April 2013 to September 2014 were tested for the plasma level of vitamin C and D[25(OH)D]. Vitamin C insufficiency was considered as <26.1micromol/L and vitamin D insufficiency as <20 ng/ml. We compared the mean plasma level of vitamin C and D[25(OH)D] according to burned percent of total body surface area (TBSA). RESULTS: Vitamin C insufficiency in 63.3% and vitamin D deficiency in 87.1%. In burn patients of TBSA> or =20%, mean plasma concentration of vitamin C and vitamin D[25(OH)D] were significantly lower (P=0.023, P<0.001). With adjusting for potential confounder such as age, sex, burn type, mean serum 25 (OH)D levels was significantly decreased 0.07 ng/ml per one percent of burned surface area (beta=-0.07, P<0.001), but with adjusting for age, sex, burn type, length of ICU stay and duration from burn injury to sampling, vitamin C and vitamin D[25(OH)D] were not significantly decreased (P=0.221, P=0.142). CONCLUSION: Vitamin C and D insufficiency were common nutrient problems in burn patients undergoing rehabilitative therapy. Further studies will be needed to establish the effective way to improve vitamin C and D status and prevent nutritional complications.

PURPOSE: Serum vitamin C is one of the indicators for antioxidant levels in the body and it is lower in cancer patients compared with the healthy population. However, there have been few studies on the levels of serum vitamin C in terminally ill cancer patients and related factors. METHODS: We followed 65 terminal cancer patients who were hospitalized in two palliative care units. We collected data of age, sex, cancer type, functional status, clinical symptoms, history of cancer therapy, and various laboratory findings including serum vitamin C level. Patients were categorized into two groups according to the quartile of serum vitamin C level (Q1-3 vs. Q4), which were compared each other. Stepwise multiple logistic regression analysis was used to identify factors related to serum vitamin C levels. RESULTS: The mean serum vitamin C level was 0.44 microg/mL, and all patients fell into the category of vitamin C deficiency. Univariate analysis showed that The serum vitamin C level was lower in non-lung cancer patients (P=0.041) and febrile patients (P=0.034). Multivariate analysis adjusted for potential confounders such as lung cancer, fever, dysphagia, dyspnea, C reactive protein, and history of chemotherapy demonstrated that odds for low serum vitamin C level was 3.7 for patients receiving chemotherapy (P=0.046) and 7.22 for febrile patients (P=0.02). CONCLUSION: Vitamin C deficiency was very severe in terminally ill cancer patients, and it was associated with history of chemotherapy and fever.

BACKGROUND: Vitamin C is an essential nutrient for maintaining human life. Vitamin C insufficiency in the plasma is closely related with the development of scurvy. However, in vivo kinetics of vitamin C regarding its storage and consumption is still largely unknown. METHODS: We used Gulo-/- mice, which cannot synthesize vitamin C like human. Vitamin C level in plasma and organs from Gulo-/- mice was examined, and it compared with the level of wild-type mice during 5 weeks. RESULTS: The significant weight loss of Gulo-/- mice was shown at 3 weeks after vitamin C withdrawal. However, there was no differences between wild-type and vitamin C-supplemented Gulo-/- mice (3.3 g/L in drinking water). The concentration of vitamin C in plasma and organs was significantly decreased at 1 week after vitamin C withdrawal. Vitamin C is preferentially deposited in adrenal gland, lymph node, lung, and brain. There were no significant changes in the numbers and CD4/CD8 ratio of splenocytes in Gulo-/- mice with vitamin C withdrawal for 4 weeks. And the architecture of spleen in Gulo-/- mice was disrupted at 5 weeks after vitamin C withdrawal. CONCLUSION: The vitamin C level of Gulo-/- mice was considerably decreased from 1 week after vitamin C withdrawal. Vitamin C is preferentially stored in some organs such as brain, adrenal gland and lung.
