The effects of $\beta$-carotene substitutionl for vitamin A and the chronic consumption of ethanol of ethanol on hepatic folate metabolism were studied it rats. The substitution of $\beta$-carotene for vitamin A depressed hepatic 10-formyl-tetreahydrofolate dehydrogenase(10-formyl-tetrahydrofolate : NADP oxidoreductase, E.C. 1.5. 1.6)activity to 65% of controls(p<0.001) and enhanced hepatic 5, 10-methy-lenetetrahydrofolate reductase(E. C. 6.3.3.2)activity by 56% with respect to control levels(p<0.001). Hepatic activity of 10-formyltertrahydrofolate dehydrogenase was depressed to about half that of control levels by ethanol administration to rats(36% ethanol diet, p<0.001). The activity of 5, 10-methyleneterahydrofolate reductase was not changed by ethanol consumption. The increased activity of 5, 10-methyleneterahydrofolate reductase and the decreased activity of 10-formyltetrahydrofolate dehydrogenase appeared to decrease the level of nonmethyl folate conezyme and the rate of one-carbon metabolism. Plasma homocysteine concentrations were significantly higher in rats fed ethanol(p<0.01) o $\beta$-carotene(p<0.001) than in controls, which suggests that increased activity of 5, 10-methylenetetrahydrofolate reductase can depress homocysteine metabolism. We concluded that dietary substitution of $\beta$-carotene for vitamin A or chronic administration of ethanol resulted in changes in the activity of hepatic folate-dependent enzymes, which could affect the distribution of folate derivatives, plasma homocysteine levels and one-carbon metabolism.

Objectives : This study aims to : (i) characterize and differentiate between two different periods of baby boomers, (ii) study the utilization of their health care services, and (iii) establish effective ways of providing better health service utilization and preventive policy strategies for upcoming and older generations. Methods : A multiple regression analysis using descriptive statistics, frequency analysis, and dummy variables was utilized to access the presence of correlations between socio-demographic factors and health care service utilization. Results : Medical insurance type, marital status, and chronic disease were factors that influenced health care service utilization. Furthermore, the factors that influenced individual medical expenses were cohabitation, inpatient days, and chronic disease. Conclusions : Primary findings and exploratory statistics revealed that there were strong correlations and interaction among some of the predictor variables. Because of the chronologically limited nature of the sample data set gathered in 2012, it would be helpful to continue to develop or research related constructs that may capture relationships more effectively among extended populations.

The purpose of this study was to identify chronic diseases and oral health care behaviors in 65-year-old individuals and to determine the factors that influence masticatory mobility. The raw data from the 8th National Health and Nutrition Examination Survey in 2020 were utilized to analyze factors associated with chewing discomfort in 1,278 elderly Koreans. Using IBM SPSS Statistics 27.0, we conducted complex sample cross-analysis to examine the difference in chewing discomfort based on general characteristics, chronic diseases, and oral health care behaviors. Additionally, we performed complex sample multiple logistic regression analysis to identify the factors associated with chewing discomfort. As a factor influencing chewing discomfort, unmet dental care was 3.33 times higher (p<0.001), and subjective oral health was 0.18 times more likely to be moderate (p<0.001) and 0.48 times more likely to be good (p<0.001) lower. In the case of arthritis, the level of chewing discomfort was high (OR=1.08, p=0.694), but there was no significant difference. As a result of the aforementioned factors, it is believed that there is a need for policies and systems to provide dental care to the elderly before their oral health deteriorates. Additionally, tailored oral health promotion programs should be implemented.

Objective : This study was designed to investigate the possibility of AR for chronic renal injury. Methods : The author first investigated the expression levels of DNA by inducing of chronic renal injury. Then, the author investigated the effects of AR on chronic renal injury induced by combination treatment with Adriamycin and cisplatin in terms of changes in body weights and renal tissues, urine volume, BUN and creatinine levels, creatinine clearance and histopathological changes in renal tissues. Total expression levels of 546 genes were elevated or lowered by induction of chronic renal injury. Genes of which whose expression levels were elevated by induction of chronic renal injury were related to the PPAR signaling pathway and fatty acid mechanism, etc. Genes of which expression levels were lowered by induction of chronic renal injury were related to the neuroactive ligand-receptor signaling pathway. Results : Oral administration of AR restored renal mass which was reduced by induction of chronic renal injury. AR also restored creatinine clearance and lowered serum BUN level. In histopathological observation, the AR group has a tendency to prevent tissue damages as shown in the chronic renal injury group. Conclusions : AR can be used to treat patients with chronic renal injury although further study will be needed to elucidate the exact mechanisms in the efficacy of AR on chronic renal injury.

A growing number of people are concerned about their sleep. There are many people with chronic sleep disorders. As there are various causes in a disease, proper treatment according to each cause is necessary for a more effective treatment. In general, insomnia is classified into five categories of physical, physiological, psychological, psychiatric and pharmacological aspects. Sedative-hypnotics including benzodiazepine and non-benzodiazepine have widely been used in chronic insomniacs. However, most hypnotics including non-benzodiazepine cause some of dependence, tolerance, impaired daytime function and rebound insomnia. Therefore, we are looking forward to proposing an effective oriental treatment for insomnia. A 71-year-old male who had suffered from cerebral infarction was admitted to our department for oriental treatment of stroke and insomnia. Initial treatment modalities with administration of paroxetine were not effective. However administration of oriental medicine' Gochimmuwoo-san(Gaozhenwuyou-san)' achieved a desirable effect.

To investigate the effects of Ixeris sonchifolia Hance diets on serum and hepatic lipid levles and enzyme activities in rats administered with ethanol chronically, Sprague-Dawley male rats were AIN-76 diet(control), control diet plus ethanol, control plus Ixeris sonchifolia Hance diet, or control plus Ixeris sonchifolia Hance diet plus ethanol for 30 days. Ixeris sonchifolia Hance diets significantly decreased the serum total cholesterol, triglyceride, LDL-cholesterol, and GOT levels that were increased due to the chronic ethanol administration. In addition, Ixeris sonchifolia Hance diets significantly decreased the liver triglyceride and total lipid levels that were increased due to the ethanol administration. The present findings, combined with previous data showing differences in the effects of cabbage diets having a high or a low level of GABA on the lipid levels and the serum Y-GPT activity of rats(Cha and OH[2000] J. Korean Soc. Food Sci. Nutr. 29, 500-505) raise the possibility that GABA in plants could have a nytraceutical role in the recovery of chronic alcohol-related diseases.

The present study was performed to investigate the effects of chronic administration of quercetin on lipid peroxidation and glutathione concentrations in rat liver. Male Sprague-Dawley rats were divided into two groups, one of which was fed a normal diet and the other a vitamin E-free diet. Each of these groups was divided further into three subgroups and treated with quercetin administered orally at either 2 or 20 mg/day or with vehicle for four weeks. The concentrations of ${\alpha}$-tocopherol in serum and liver increased following quercetin treatment, and these increases were significantly greater in rats maintained on vitamin E-free diet.

Objectives: The purpose of this study was to examine the impact of chronic disease on oral health behavior. Methods: The subjects were 317 adults over 30-years old living in urban and rural areas. They were selected by convenience sampling method and filled out the self-reported questionnaire. The questionnaire consisted of general characteristics, dental treatment, chronic disease, and oral health behavior including oral health self-care behavior and professional oral health care. Results: The self-care oral health behavior and the professional oral health care had a negative correlation with the chronic diseases. Especially, the self-care oral health behavior and the professional oral health care had a statistically significant negative correlation with hypertension and osteoporosis. Multiple regression analysis was performed after including general characteristics, dental treatment, chronic disease. Meanwhile the presence of chronic disease had a significant influence on the self-care oral health behavior and the professional oral health care. Hypertension and Osteoporosis were the most influential factors of chronic diseases and had a significant influence on the oral health behavior. In conclusion, the chronic diseases aggravated the oral health behavior practice. Conclusions: presence of chronic disease affects oral health behavior. Therefore, the effective intervention and education programs related to oral health care are necessary to enhance adult's oral health behavior and total health. The continuous follow-up study will determine the causal relationship between oral health behavior and the presence of chronic disease.

The system most likely responsible for the accelerated metabolism of alcohol with chronic ingestion or at high blood ethanol levels, is the microsomal ethanol-oxidizing system(M EOS). While the increase in the MEOS with chronic ethanol ingestion is thought to be adaptive, it may also have serious adverse effects on the liver. The rates of the NADPH-dependent oxygen consumption by the liver microsomes from the prolonged ethanol fed rats were 2 times higher than the rates from the non-treated rats. With the alcohol ingestion, the total SH and nonprotein SH contents showed the significant decrease and at the same time, MDA in liver and GOT and GPT levels in blood showed the significant increase, which suggests the occurrence of liver damage due to the oxidative stress caused by chronic alcohol consumption. The mitochondrial aldehyde dehydrogenase(ALDH) activity was decreased by chronic ethanol ingestion, whereas the alcohol dehydrogenase activity and the cytosolic ALDH activity were not altered. These results suggest that the induction of cytochrome P450 by the chronic alcohol ingestion increases the oxidative stress which seems to result in the altered the physiological states of the liver including the ALDH activity, which may in turn to lead to the liver disease.
