Purpose : Treatment of primary nocturnal enuresis (PNE) includs folk remedies and various treatments based on pathogenesis. We assessed the therapeutic effect of nocturnal water restrict ion as the primary treatment of PNE. Materials and methods : From October 1998 to June 1999, 41 children with PNE (>3 wet nights per week) who visited Ewha Womans University Mokdong hospital and who had good compliances to nocturnal water restriction for 2 months were included. Before and during nocturnal water restriction, daily fluid intake and urine volume were recorded for 2 days every 2 weeks. Responses to nocturnal water restriction were classified according to the decrease of wet nights as complete (>90$\%$), partial (50-90$\%$) and no (<50$\%$) response. Predictors such as age, sex, daytime voiding dysfunction, fluid intake, urine volume, maximum urine volume per void and fasting urine osmolality were evaluated. Results . The response rate to nocturnal water restriction fir 2 month was 82.9$\%$(34/41) [complete response 39.0$\%$(16/41), partial response : 43.9$\%$(18/41)]. The response rate to nocturnal water restriction was significantly higher in monosymptomatic PNE than polysymptomatic PNE and more effective in PNE with or nocturnal fluid intake, nocturnal urine volume, and maximum urine volume than lower nocturnal fluid intake, nocturnal urine volume and maximum urine volume per void (P<0.05). Nocturnal urine volume, maximum urine volume per void and luting urine osmolality after nocturnal water restriction has significantly increased higher in complete response and partial response group than in no response group (P<0.05). Conclusion : The nocturnal water restriction was effective in monosymptomatic PNE with nocturnal polydypsia, nocturnal polyuria and high bladder capacity.

Purpose By ingestion of 18F-FDG of kidney of PET/CT during the inspection, if additional examination is required, depending on whether you want to water intake, we want to confirm a change in the rate of decrease of F-18 FDG of the kidney. Materials and Methods The 80 patients without kidney disease were performed PET/CT examination. Device was analyzed after setting the kidney to a three-dimensional region of interest. In patients require additional examination, and inspection after 30 minutes, a PET/CT torso examination after the water of the 500 cc ingested at a time. After the addition of both water intake group and no hydration group of kidney of SUV, it was compared with PET/CT torso scan. Results High and low of the kidney SUV did not show a significant difference in the rate of decrease. Reduction rates of background (BKG) of additional examination was 2.8% and reduction rates of SUV was 49.7% (Hydration) : -6.8% (No hydration), so did show a significant difference. In the image blind test, the average point score of hydration and no hydration was 34.25 : 17.25. Conclusion An undercurrent of 18F-FDG in the kidney at the time of torso examination, it was confirmed that the reduction rate after the addition of water intake is high. It is considered that can be expected to improve the quality of an image due to a decrease in elongation through the kidneys examination with additional fluid intake as needed intake.

Purpose: The purposes of this study were to examine the amount of daily fluid intake among nursing home residents and to explore the caregiver's perceived barriers to elderly's fluid intake. Method: Data was collected from 111 nursing home residents and 64 caregiver's in 4 nursing homes. A random, non-consecutive three days of 24 hour fluid intake was measured and recorded. The caregiver's perceived barriers to elderly's fluid intake was assessed using a structured questionnaire. Results: The average amount of daily fluid intake was 1,035(SD=359)ml with the range of 210m1 to 2,050ml. About 52% (n=58) of the subjects had a less than adequate fluid intake. The amount of daily fluid intake was significantly associated with age, mental status, physical functioning, and the number of oral medications ordered. The most frequently mentioned caregiver's perceived barrier was elderly's concern about incontinence with increased fluid intake. Conclusion: Inadequate fluid intake among nursing home residents is prevalent. To enhance adequate hydration of nursing home residents, an institution wide nursing intervention is necessary.

The purpose of this study aims guarana ingestion to possibly be Ergogenic Aids(EA) for elite male athletes who do long time exercises. Participators who play long distance belong to H-university. They are measured HRmax by polar and treadmill, and they do run on the treadmill for 60 minutes with HRmax 70%. Participators ingest 200ml guarana and water for 5 times. They were drawn blood for 3 time such as before 30 minutes, after finish, and after 30 minutes later. Data processing was repeated of the measuring, two way repeated ANOVA, according to guarana ingestion, water ingestion, and treatment time. The result of this study identifies that guarana ingestion is more positive effect with glucose, Free fatty acid, and lactic acid than water. Hence, guarana ingestion is including function of EA to increase reserving energy on the body for rising kinetic ability.

Purpose: With the introduction of PET since 1994, test methods have made rapid progress. Accordingly, the studies on the diagnosis and treatment of cancer as well as treatment response evaluation PET test are useful. However, it is difficult to divide stomach lesions and secretion. The purpose of this study is to reduce additional shooting by dividing lesions and secretion of stomach. Materials and Method: This study aiming at total 228 cancer patients was conducted from Aug 18 to Sep. 10, 2010. Among them, 115 patients had a test without water intake before shooting from Aug. 8 to 31 and 113 had a test after drinking 500 cc water right before shooting from Sep. 1 to 10 The Discovery ST PET/CT (GE Healthcare, USA) was used, and pearson's chi-square test was conducted to analyze significance through SPSS (Ver.18). Results: Among the total 228 cancer patients, there were 115 who had a test without water intake before shooting, 89 who had no double additional shooting, 13 who had stomach additional shooting and 13 who had other additional shooting. In addition, 109 had no additional shooting among 113 who had a test after taking 500 cc water, 1 had stomach additional shooting and 3 had other additional shooting. According to the findings above, the patients who had a test without water intake show reduced additional shooting, but for more exact significance, pearson's Chi-square test was carried out and the significance percentage was 0.001 that is smaller than 0.05, which means two groups have a significant relationship. As the minimum expectation frequency was 6.94 and there was no expectation frequency smaller than 5, so that it doesn't need to carry out pearson's exact verification. Conclusion: The above analysis has found that if one drinks 500cc water before the test, not only stomach additional shooting but also other additional shooting can be dramatically reduced, and test delay can be also reduced.

This study was performed to investigate the influence of giant embryo feeding on hypoglycemia in streptozotocin-induced diabetic rats. Streptozotocin -induced diabetic rats were fed four kinds of experimental diets such as corn starch diet as a control, polished rice diet, brown rice diet and giant embeyonic rice diet for 6 weeks. The body weight gain diabetic of control was signaficantly suppressed compared to that of the normal. The supplementation of giant embryo increased the surivival rate. Feeding of giant embryo appeared to have ameliorating effects on diabetic symptoms including features such as polyphasia, polyuria. Giant embryo shortened gastrointestinal transit time and increased total fecal weight, total fecal dry weight and fecal water content compared with diabetic control. Giant embryo showed fasting blood glucose lowering effect compared with diabetic control. The disaccharidase activities in proximal part of intestine such as maltase sucrase and lactase in giant embryo feeding groups were lower than diabetic control. The results of this study show that giant embryo supplementation may have a beneficial Veffect on the hypoglycemia may be useful in the diet therapy for diabetic.

The maintenance of the osmolality of body fluids within a very narrow physiologic range is possible by water balance mechanisms that control the intake and excretion of water. Main factors of this process are the thirst and antidiuretic hormon arginine vasopressin (AVP), secretion regulated by osmoreceptors in the hypothalamus. Body water is the primary determinant of the osmolality of the extracellular fluid (ECF), disorders of body water homeostasis can be divided into hypo-osmolar disorders, in which there is an excess of body water relative to body solute, and hyperosmolar disorders, in which there is a deficiency of body water relative to body solute. The sodium is the predominant cation in ECF and the volume of ECF is directly proportional to the content of sodium in the body. Disorders of sodium balance, therefore, may be viewed as disorders of ECF volume. This reviews addresses the regulatory mechanisms underlying water and sodium metabolism, the two major determinants of body fluid homeostasis for a good understanding of the pathophysiology and proper management of disorders with disruption of water and sodium balance.

Objectives: Water constitutes a majority of the human body and is essential for health. In addition, water intake can prevent dental caries by improving salivary lubrication and self-cleaning. This study aimed to determine the relationship between the amount of daily water intake and the symptoms of oral disease in Korean adolescents. Methods: We used data from the Korea Youth Risk Behavior Web-based Survey (KYRBS), conducted in Korea in 2021, and identified the relationship between daily water intake and oral disease symptoms in Korean adolescents. KYRBS is a nationwide cross-sectional survey conducted by the Korea Disease Control and Prevention Agency (KDCA), and a total of 54,848 participants were included in this study. Results: After adjusting for confounding factors, logistic regression analysis showed that tooth pain was more often experienced by those who drank less than two cups of water per day (odds ratio [OR]: 1.14; 95% confidence interval [CI]: 1.01-1.30) than those who drank five or more cups of water per day. Conclusions: A low daily water intake is associated with tooth pain, a symptom of dental caries. The results of our study suggest that increasing water intake may reduce dental caries. Therefore, adequate water intake may help prevent dental caries.
