The purpose of this study was to assess risk factors associated with food insecurity in the Korean elderly aged over 65 years using data from the Korea National Health & Nutrition Examination Survey 2013 (KNHANES VI). A total of 1,200 subjects were analyzed among the participants of the KNHANES 2013 by using SPSS statistics complex samples (ver. 21.0). Food insecurity was measured by using the modified US Household Food Security/Hunger Survey Module. Thirteen percent of subjects lived in food insecure households. There were differences in the prevalence of food insecurity according to sex, educational level, income level, and household structure. Mean age of the food insecurity group was significantly higher than that of the food security group. The results of logistic regression analysis showed that food insecurity was significantly associated with alcohol intake (OR: 1.82), prevalence of melancholy (OR: 2.07) and suicidal thoughts (OR: 2.67), and intake deficiency of energy (OR: 1.60), calcium (OR: 1.97), iron (OR: 1.97), potassium (OR: 1.96), riboflavin (OR: 1.76), and niacin (OR: 1.64), while not with smoking, physical activity, chronic diseases including obesity, anemia, diabetes, and osteoarthritis, and deficiency of protein, vitamin A, thiamin and vitamin C. These findings suggest that food insecurity is strongly related to mental health and certain nutrient intakes. Prospective research is needed to establish the effects of food insecurity on chronic diseases.

Objectives : This study was carried out to research the protective effects of Sagunja-Tang(SA) through in vivo experiments, and tried to investigate the relation between oxidation of liver tissues and deficiency of Qi. Methods : Acute liver injury which initiated from free radical induced by $CCl_4$, were applied to mice and metabolic data were obtained. In order to measure the degree of liver injury, serum level of alanine aminotransferase(AST), aspartate aminotransferase(ALT), creatinine, blood urea nitrogen(BUN), total protein(TP) and glucose were measured. Lipid peroxidation of liver slice was examined by measuring malondialdehyde(MDA), a product of lipid peroxidation. Results : SA had protective effects on $CCl_4$ induced acute liver injury by decreasing serum level of ALT. Kidney injury was induced by injection of $CCl_4$ too, and SA protected kidney injury by decreasing serum level of creatinine and BUN. Conclusions : Through this study, we found that SA have healing effects on liver and kidney injury of $CCl_4$ induced oxidative stress that is similar to deficiency of Qi. And further studies have to be followed to certify the mechanisms.

The present investigation has been made to study the deficiency symptoms of boron on the formation of cell wall and the development of the individual components of the orchid cell wall. Analytical samples were taken from two sources; one from the individual orchid plants started from an apical meristem culture followed by the generation of the protocorm-like body which was developed into a plant, the other from the plant cultivated in water for 30 days. The amount of boron in the cultrues were controlled and the deficiency symptoms were observed under theelectron microscope, optical microscope with samples taken from the zones of elongation of leaves and compared the dry weight of cell walls and finally the various fractions of the cell wall components. The following results were obtained: (1) The growth of roots and leaves was hampered in the boron deficient plants. (2) In the boron-deficient leaves a severe necrosis and cracks were developed in the tissue of zone of elongation besides the decrease in growth. (3) under the electorn microscope the cell walls of boron-deficient plants showed rough undulated structures unlike the smooth control cell walls. (4) the dry weight of total cells and cell walls of boron deficient plants were higher than the control plants. (5) In the boron deficient plant the amout of pectin and hemicellulose isolated from cell walls were higher and the amount of protein was lower than the controlled plots.

A novel strategy was developed for isolating suppressors from sporulation-deficient mutants. The mutation in the BCY1 gene, which codes for the regulatory subunit of cAMP-dependent protein kinase, when homozygous, results in diploids being meiosis and sporulation deficient. Two plasmids, YCp-MAT.alpha. and YEp-SPOT7-lacZ, were introduced into MAT.alpha. BCY1$\^$+/ or MAT.alpha. bcy1 haploid cells. The transformant of the BCY1$\^$+/ haploid cell produced .betha.-galactosidase under nutrient starvation, but the bcy1 transformant did not. Using this system, the mutagenesis experiment performed on the bcy1 transformant strain resulted in a number of sporulation mutants that produced .betha.-galactosidase under nutrient starvation. One complementation group, sob1, was identified from the isoalted suppressor mutants and characterized as a single recessive mutation by tetrad analysis. Genetic analysis revealed that the sob1 mutation suppressed the sporulation deficiency, the failure to arrest at the G1 phase of the cell cecle, and the sensitivity to heat or nitrogen starvation caused by the bcy1 mutation. However, the sob1 mutation did not suppress the sporulation deficiency of ime1 and of ime2 diploids. These results suggest that the sob1 mutation affects a gene which functions as a downstream regulator in both meiosis and cell cycle regulation.

This survey was carried out to obtain an information for the improvement of nutrition and the enlightment of dietary life in a near by area of DMZ during the later part of July, 1981. A total of 50 households were selected from Tonghyun-ri, Yunchun-eup, Yunchun, Gyunggi province. As a results of survey, the average intake of vegetable food was as high as 98% and that of the protein intake of good quality was not sufficient. Generally energy and nutrition intake were higher than the recommended dietary allowances and national nutrition survey data of Korean. There were no remarkable clinical symptoms related with nutritional deficiency on the entire target, but were some clinical symptoms related with vitamin deficiency on the children. The housewives lived at target area have a tendency to like the food which they are sued to eat daily and that food was mostly self-supplyed.

Objective Sjogren's Syndrome is a chronic inflamatory disorder characterized by lymphocytic infiltration of lacrimal and salivary gland. It may be associated with renal disease such as tubulonephritis or glomerulonephritis. Proteinuria is a kidney disorder resulting in an abnormally high amount of protein in the urine. When the glomeruli are damaged, proteins of various sizes pass through them and are excreted in the urine. This report is a case of proteinuria with Sjogren's Syndrome. Methods The patient was diagnosed as kidney yang deficiency syndrome and treated with Woogyu-eum, Sa-am acupuncture therapy and bee venom acupuncture therapy. Visual Analog Scale was used to estimate the clinical symptoms. Results Clinical symptoms and proteinuria were improved without steroid therapy. Conclusion Therefore, we concluded that oriental medical therapy may be useful to treat proteinuria with Sjogren's Syndrome.

Long-chain fatty acid oxidation disorders (LC-FAOD) are an autosomal recessive inherited rare disease group that result in an acute metabolic crisis and chronic energy deficiency owing to the deficiency in an enzyme that converts long-chain fatty acids into energy. LC-FAOD includes carnitine palmitoyltransferase type 1 (CPT1), carnitine-acylcarnitine translocase (CACT), carnitine palmitoyltransferase type 2 (CPT2), very long-chain acyl-CoA dehydrogenase (VLCAD), long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD), and trifunctional protein (TFP) deficiencies. Common symptoms of LC-FAOD are hypoketotic hypoglycemia, cardiomyopathy, and myopathy. Depending on symptom onset, the disease can be divided as neonatal period, late infancy and early childhood, adolescence, or adult onset, but symptoms can appear at any time. The neonatal screening test (NBS) can be used to identify the characteristic plasma acylcarnitine profiles for each disease and confirmed by deficient enzyme analysis or molecular testing. Before introduction of NBS, the mortality rate of LC-FAOD was very high. With NBS implementation as routine neonatal care, the mortality rate was dramatically decreased, but severe symptoms such as rhabdomyolysis recur frequently and affect the quality of life. Triheptanoin (Dojolvi^®), the first drug for pediatric and adult patients with molecularly confirmed LC-FAOD, has recently been approved by the US Food and Drug Administration in 2020. In this review, the diagnosis of LC-FAOD and treatment including triheptanoin are summarized.
