This study is assessed the urinary hippuric acid (HA) concentration in toluene-exposed workers. Toluene is widely used in the coating, printing, painting and petroleum industries. We analyzed the hippuric acid level of toluene-exposed workers (males: 198, females: 63) from 2008 to 2010 and examined the relationship between hippuric acid and the characteristics of their work. The measurements of the urinary hippuric acid were confirmed by high-performance liquid chromatography. Among the subjects, males had on average more work experience than females (males: 9.17 years, females: 4.45 years), but females showed a higher hippuric acid concentration levels than males (males: 0.26 g/L, females: 0.75 g/L). The mean of the HA concentration according to the age group was 0.19 g/L in 30's, 0.30 g/L in 40's, 0.54 g/L in 50's, 1.36 g/L in 60's. Those in their 60's had the highest concentration. The mean of HA concentration according to the type of work was 0.70 g/L for the coating, 0.52 g/L for the painting, and 0.16 g/L for the printing industries, revealing that the workers in the coating industry had the highest concentration. By the highest order, the mean of HA concentration by working period was as follows; less than 5 years, ${\leq}5\;years{\sim}<10\;years$. The factors that influence the HA concentration are not only how long one is exposed to toluene but also the type of work, worker's age, and their gender.

Purpose: The aim of this study was to analyze the association between sodium excretion and obesity for healthy adults in the Gwangju area. Methods: The participants included 80 healthy adults aged 19 to 69 years in Gwangju. The dietary intake and sodium excretion were obtained using the 24-hour recall method and 24 hour urine collection. The participants were classified into two groups according to the amount of urinary sodium excretion: (${\leq}141.75mmol/dL$, > 141.75 mmol/dL). Results: After adjusting for sex, age, smoking history, and income, the high excretion of sodium group was significantly higher for weight, body mass index, body fat mass, percent body fat, visceral fat area (VFA), waist circumference, hip circumference, and WHR. The energy and nutrients intake were significant after adjusting for sex, age, smoking history, and income. The LSE group had a significantly higher fat intake and Na/K intake ratio. The HSE group had significantly higher fiber intake, and K intake. As the amount of urinary sodium excretion increased, the risk of obesity before correction was 3.57 (95% CI: 1.13-11.25) times greater, and the risk of obesity of T3 increased significantly by 3.33 times (95% CI: 1.05-10.59). After correcting for sex and age, the obesity risk of T2 increased significantly by 4.23 times (95% CI: 1.11-16.06), and after correcting for sex, age, smoking history, and income, the obesity risk of T2 increased significantly by 6.81 times (95% CI: 1.44-32.19) the risk of obesity. Conclusions: An association exists between sodium excretion and obesity in Korean adults. In this study, the high excretion of sodium group was obese and the risk of obesity was higher than the low excretion of sodium group.

Since it has been suggested that atrial receptor may be involved in the mechanism of extracellular volume regulation, it was shown that the granularity of atrial cardiocytes can be changed by water and salt depletion, and that an extract of cardiac atrial tissue, when injected intravenously into anesthetized rats, was shown to cause a large and rapid increase in renal excretion of sodium. Various natriuretic peptides were isolated and synthetized, and the effects were investigated by many workers. Most studies, however, have been carried out under anesthesia and there have teen some controversies over direct effect of the factor on the renal function. Therefore, it was attempted in this study to access the effects of an atrial extract and a synthetic natriuretic factor in unanesthetized rabbits. Intrarenal arterial infusion of atrial extract caused a rapid increase of urinary volume and excretion of sodium. Glomerular filtration rate and renal plasma flow were both increased with no change in filtration fraction. The ventricular extract produced no change in urinary excretion of electrolytes, nor in renal hemodynamics. Intrarenal infusion of synthetic atrial natriuretic factor caused increases of renal excretory rate of sodium, chloride and potassium, and $FE_{Na}$. Glomerular filtration rate, renal plasma flow increased. And free water clearance also increased. Accentuated excretory function correlated well with increased glomerular filtration rate and renal plasma flow during infusion and for 10 minutes following the cessation of the infusion. Renin secretion rate decreased during constant infusion of atrial natriuretic factor. However, no correlation was found with the changes in glomerular filtration rate, renal plasma flow, or urinary excretion of sodium. These results suggest that atrial extract or atrial natriuretic factor induces changes in renal hemodynamics, as in excretion of electrolytes either indirectly through hemodynamic changes or directly by inhibiting tubular reabsorption. At the same time, renin secretory function is affected by the factor possibly through an unknown mechanism.

The purpose of this study is to determine the effect of the first experience of the clinical experience for psychiatric nursing on the urinary 17-ketosteroid (KS) and 17-hydroxycorticosteroid (OHCS) of the nursing students. We analyzed the urine of fifteen students on curriculum who were students of D college in K city, compared with the control. In terms of 17-KS, at the end (4 PM) of the first day (p=0.001) and the last day (p=0.003), there was statistically significant difference between the control and the experimental group. In terms of 17-OHCS, at the end of the first day, there was statistically significant difference between the control and the experimental group (p=0.005), and between at the beginning (8 AM) and at the end during the clinical experience (p=0.035). At the last day, also, there was significant difference on the statistics between at the beginning and at the end in both the control (p=0.018) and the experimental group (p=0.004). In conclusion, 17-KS and 17-OHCS may be used as a indicator of the amount of stress to improve the educational environment for the students.

Purpose: This study was to verify the effects of a fluid therapy education program for aged stroke patients for preventing dehydration, pyuria and bacteriuria. Methods: The study employed a non-equivalent control group pretest-posttest design in quasi experimental basis. Subjects were 38 stroke patients (20 in the experimental group and 18 in the control group) older than 65, hospitalized in a senior care center in S city, Korea. Results: The amount of daily average fluid intake, normal ratio of blood urea nitrogen-creatinine ratio, serum $Na^+$ and urine white blood cells were increased significantly in the experimental group. Normal ratio of bacteriuria increased in the experimental group, but not significantly. Conclusion: The education program is considered to be an effective nursing intervention tool for preventing dehydration and urinary tract infections which related to the secondary wellness of aged stroke patients. However, longer term study is necessary for better quality of nursing and developing more specific education programs for aged stroke patients usually hospitalized for a long period of time.

Oryeong-san which was first recorded in Shanghanrun describing the treatments of acute febrile disease is one of the frequently used oriental medicines. Oryeong-san has been prescribed for the treatment of symptoms accompanied by edema. The purpose of this study was to examine the diuretic effects of Oryeong-san by different routes of administration. Oryeong-san (100 mg/kg body weight) was administrated by three different routes in Sprague-Dawley rats: intravenous infusion, intraperitoneal injection and oral intake. Oral intake of Oryeong-san significantly increased urinary volume and excretion of $Na^+$, $Cl^-$, and $K^+$ compared to vehicle-treated control group. The effects were concentration-dependent. Intravenously administrated Oryeong-san increased urinary volume and electrolyte excretion but without significance in hydrated (0.02 ml/min/rat for 90 min) anesthetized rats. Similarly, intraperitoneally injected Oryeong-san had no effects on water and urine electrolyte excretion compared with saline control group. These findings suggest that Oryeong-san has different effects on water and electrolyte balance by routes of administration.

We treated a 51 year-old female patient of neurogenic bladder. The patient complained of urinary incontinence, lack of urine sense, loss of right leg sense etc. The symptoms developed right after spinal stenosis surgery. The symptoms didn't show any improvement continually. But after admission and treatment in our hospital, symptoms were improved from severe to mild and the score of Assesment of Bladder function got better. We continued to prescribe the herbal medicine over 8 weeks and could observe that symptoms were improved. This result suggests that oriental medical therapy is useful enough to treat the neurogenic bladder. Therefore further study of the approach and application of this treatment for neurogenic bladder would be necessary.

본 연구는 여자대학생을 대상으로 장기간의 자율적 저염식 실시가 짠 맛에 대한 인지와 기호에 영향을 미쳐 나트륨 섭취나 혈압에 변화를 가져 올 수 있는지를 조사하고자 실시되었다. 14명의 실험군 대상자들은 나트륨 관련 영양교육과 정보를 제공받아 저염식을 하도록 지시 받았고 10명의 대상자는 평상시의 식생활을 유지하도록 하였다. 짠 맛의 인지와 기호는 9점 척도의 관능검사로 평가하였고 뇨 나트륨 배설량과 최적 염미 나트륨 정량 분석하였으며 혈압을 측정하였다. 주요 연구 결과는 아래와 같다. 1) 연구 시작시의 실험군과 대조군은 나트륨 관련 식행동, 신체 계측치, 혈압, 24시간 회상법에 의한 나트륨 섭취량, 6단계의 염분용액에 대한 짠 맛 인지나 기호에서 차이가 없었다. 2) 6개월의 저염식 실시 후 실험군 대상자들은 0.5% 이하 염분 용액에서 짠 맛 인지도가 높아졌고 대조군은 낮아져 저염식 실시로 낮은 농도의 염분에 적응한 듯하나 연구시작과 종료시의 paired t-test에서 통계적 유의성은 없었다. 기호도는 시작 시에는 두 군 모두 0.5% 염분 용액을 가장 선호했고 연구 종료시 대조군은 0.75%와 0.5% 염분 용액에 비슷한 기호도를 보인 반면 실험군은 0.5%, 그 다음으로 0.3% 용액에 높은 기호도를 보였으나 그 변화가 유의적 수준은 아니었다. 3) 최적 염미 나트륨 농도는 실험군에서 105.6 mmol에서 저염식 적응 후 80.7 mmol로 유의적 (p = 0.015) 감소를 보였고 대조군은 변화가 없었다. 뇨 나트륨 배설량은 대조군은 연구 시작과 종료시 차이가 없었고 실험군은 연구 종료시 1,398 mg에서 906 mg으로 유의적 감소를 하였다. 4) 수축기 혈압은 실험군 대상자에서 111 mmHg에서 106 mmHg로 유의적으로 감소하였고 이완기 혈압은 대조군, 실험군 모두에서 유의적으로 감소하였다. 혈압과 뇨 나트륨 배설량은 상관관계를 나타내지 않았다. 5) 최적 염미 나트륨 농도와 뇨 나트륨 배설량은 양의 상관관계 (r = 0.418)을 보여 짠맛에 대한 기호가 나트륨 섭취량에 영향을 미친 것으로 보인다. 최적 염미 나트륨 농도와 뇨 나트륨 배설량은 0.5% 이하의 낮은 염분 용액에 대한 짠 맛의 인지와는 음의 상관관계 (r = -0.338~-0.399)를 보여 저염식을 하는 대상자는 낮은 염도에도 잘 반응함을 보여 주었다. 본 연구의 대상자들은 6개월 간의 실험 경과 후 최적 염미도와 뇨 중 나트륨 배설량에서는 대조군과 실험군의 차이가 분명하였고 관능검사 결과는 0.5% 이하의 저염 농도에 실험군 대상자들이 짠 맛 인지와 기호도가 유의적이지는 않으나 향상하였다. 혈압은 수축기 혈압이 실험군에서만 유의적으로 감소하여 전반적으로 6개월 간의 저염식 적응이 유효한 듯하다. 그러나 본 연구결과만으로는 저염식에 적응해 가는 변화과정을 알 수 없고 분석 자료의 표준편차로 보아 개인차 커 일부 비적응자가 있었음을 알 수 있다. 앞으로 저염 적응 기간 중 개인별 반응과 함께 여러 시점에서의 관찰이 필요하다고 본다.
