The purpose of this study was to investigate Na and K balances in healthy adult women. Anthropometric assessments, biochemical analysis of blood, 3-day dietary flood records and collections of 3-day food, 24-hr urine and faces were performed to evaluate intakes and excretions of Na and K in 20 college women living in Seoul. The mean BMI and blood pressure of the subjects were 21.08 and 110.25/67.50mmHg, respectively. Mean daily intake of energy was 1578.84kcal, 79% of Korean RDA. Also, daily intakes of Na and K ware 120.86mEq and 44.20mEq. The urinary and fecal excretions of Na were 99.88 and 4.45mEq/day, and those of K were 30.41 and 8.66mEq/day, respectively. The body retention, retention rate, and apparent absorption of Na were 17.11mEq, 13.23%, and 96.31%, and those of K were 5.82mEq, 8.69%, and 80.12%, respectively. The urinary and fecal Na/K ratio were 3.48 and 0.52. There were significantly positive correlations between 1) urinary Na, K excretions and intakes of Na or K, 2) urinary K and BMI, 3) serum K and serum globulin, and 4) urinary Na excretion and serum haptoglobin level, respectively. The results of this study show that Na intake was higher and K intake was lower than those of other advanced nations. Therefore, nutrition education show instruct people to reduce Na intake and to increase K intake.

본 연구는 ET가 함유된 소금의 섭취가 요를 통한 나트륨 배출에 미치는 단기간의 효과를 확인하기 위하여 연구를 수행하였다. 실험기간 동안 일반소금을 섭취한 대조군, ET가 함유된 소금을 섭취한 실험군 Salt + ET에서 식이섭취 및 체중증가는 Day 7에는 통계적으로 유의적인 차이가 없었으나 물 섭취량은 Day 1과 Day 7에서 모두 Salt + ET에서 높은 경향을 보였다. 요량을 측정한 결과 Salt와 비교하여 ET를 섭취한 Salt + ET에서 약 27% 높았으며 Day 1과 Day 7에서 모두 통계적으로 유의적인 증가가 관찰되었다 (p < 0.05). 시험기간 동안 요를 통해 배출된 총 나트륨과 칼륨의 양을 산출한 결과 ET를 섭취한 Salt + ET에서 1일차와 7일차에 모두 높게 나타났으며, 특히 7일차에 ET를 섭취한 Salt + ET에서 유의적으로 증가하였다(p < 0.01). 혈중 나트륨 농도와 칼륨 농도에서는 두 그룹간 유의적인 차이가 없었다. 이러한 결과들을 종합하여 볼 때 단기간의 ET 섭취에도 ET의 이뇨작용으로 인한 요량의 증가를 통해 전해질 배출에 도움을 줄 수 있으며 부작용이 많은 이뇨제들 대신으로 쓰일 수 있는 이뇨제 역할을 할 수 있을 것으로 사료되며, 향후 더 많은 연구와 분석들을 통해 혈압 강하제의 잠재적인 효과도 기대할 수 있을 것으로 사료된다.

Effects of cadmium exposure on renal $Na^+$ and $K^+$ transports were studied in rats. During the course of cadmium treatment (2 mg Cd/kg/day, s.c. injections for 3 weeks) renal tubular transports of $Na^+$ and $K^+$ were evaluated by lithium clearance technique. During the early phase (first week) of cadmium treatment, urinary $Na^+$ excretion decreased drastically and this was due to an increased $Na^+$ reabsorption both in the proximal and distal nephrons. During the late phase (third week) of cadmium treatment, filtered $Na^+$ load was decreased by reduction in GFR, but the renal $Na^+$ excretion returned to the control level due to impaired $Na^+$ transport in the proximal tubule. Urinary excretion of $K^+$ did not change during the early phase, but it rose markedly during the late phase of cadmium treatment. These results indicate that a light cadmium intoxication induces a $Na^+$ retention, and a heavy intoxication results in a $K^+$ loss. Possible mechanisms for these changes are discussed.

rat에 주사된 lithium 이온의 배설에 미치는 수종의 corticosteroid의 영향을 검색한 결과 다음과 같은 결론을 얻었다. 1. fludrocortisone을 10mg/kg 투여하여 혈청내 lithium 농도를 줄일 수 있었고, lithium의 뇨중 배설량도 증가시켰다. 2. dexamethasone을 0.1mg/kg 투여하여 혈청내 lithium 농도를 줄일 수 있었고, 1mg/kg을 투여하여 lithium의 뇨중 배설량도 증가시켰다. 3. dexamethasone에 의하여서는 혈중 $Na^+$의 $K^+$에 대한 농도비가 감소하였고, 반대로 뇨중 $Na^+$의 $K^+$에 대한 농도비가 감소하였다. 이상의 실험 결과를 미루어 corticosteroid는 lithium의 뇨중 배설량을 증가시키고 그 혈중 농도를 감소시킬 수 있으나, 이러한 작용은 신장을 통한 $Na^+$ 이나 $K^+$의 이동과는 전혀 상관이 없다고 생각된다.

Phellinus linteus (Hymenocaetaceae) is a member of Basidiomycotinae, which has been used for the treatment of gastric cancer, non-insulin-dependent diabetes mellitus, diarrhea, and menstrual irregularity. To investigate the diuretic action of Phellinus linteus, urinary volume, serum parameters and urinary electrolytes in HgCl$_2$-induced acute renal failure rats in vivo were measured. The results showed that its MeOH extract produced significant increases on urinary volume, sodium and potassium excretion, and revealed lowering effects of the abnormally elevated BUN, creatinine and uric acid value in acute renal failure rats.

Purpose of this study was to investigate correlation between blood pressure (systolic and diastolic) and dietary sodium, potassium intake pattern in the family members of normal cerebrovascular (CVA) disease, excluding patients themselves. Both mean values of systolic (125.8$\pm$23.7 vs 119.3$\pm$19.2mmHg) and diastolic(76.1$\pm$16.7 vs 71.6$\pm$12.5mmHg) bllood pressure in the family members of cerebrovascular disease patients were significantly higher than those of normal subjects. Systolic blood pressure was positively correlated with age, weibght, sodium in soybean paste, potassium in hotpepepr paste, soybean paste and meats in normal subjects group. In the family members of cerebrovascular patient, systolic blood pressure was possively correlated with age, weight, sodium in soy sauce, drinking water and potassium in soups. Interestingly, table salt intake was positively correlated with systosolic blood pressure in the family members of cerebrovascular disease patients. Diastolic bolld pressure was positively correlated with age, weight, table salt intake potassium in hotpepper paste and soybean paste in normal subjects group. Diastolic blood pressure was positively correlated with age, weight and table salt intake in the family members of cerebrovascular disease patients. Urinary potassium excretion was negatively correlated with both systolic and diastolic blood pressure in the family members of cerebrovascular disease patients.

고혈압의 유발 원인과 관련이 있는 나트륨의 섭취를 줄일 수 있는 방법을 모색하기 위해 건강한 20대 성인여성 9명을 대상으로 NaCl-KCl 혼합식염으로 조리한 식이를 섭취하도록 한 후 24시간 소변으로 배설되는 나트륨 양을 조사하여 나트륨 섭취량이 평상시보다 어느 정도 감소되는가를 보고자 하였다. 1) 3일간의 일상식이 섭취상태를 조사한 결과 연구대상자들이 섭취한 1일 평균 열량은 1,872.0 kcal였으며 나트륨과 칼륨의 1일 평균 섭취량은 각각 178.2 ${\pm}$ 46.0 mEq, 56.4 ${\pm}$ 21.9 mEq로 나타났다. 2) 실험기간동안 제공된 실험 식이에서 대상자들이 섭취한 열량은 평균 2,031.2 kcal였으며 나트륨의 섭취량은 평균 130.2 mEq이었으며, 칼륨의 섭취량은 평균 120.4 mEq이었다. 3) 조사대상자들의 혈압은 실험 시작 전 수축기 혈압과 이완기 혈압의 평균이 각각 104.6 ${\pm}$ 4.9 mmHg, 69.2 ${\pm}$ 6.3 mmHg였다. 실험식이 섭취 기간 동안 수축기 혈압과 이완기 혈압은 각각 108.1 ${\pm}$ 8.0 mmHg, 70.4 ${\pm}$ 5.7 mmHg로 나타났다. 4) 일상식이 섭취기간동안 소변의 평균 나트륨과 칼륨의 배설량은 각각 139.6 ${\pm}$ 37.3 mEq, 27.7 ${\pm}$ 14.7 mEq이었다. 소변의 나트륨/칼륨 비율은 6.6 ${\pm}$ 4.1이었다. 실험식이 섭취기간동안 소변의 평균 나트륨과 칼륨의 배설량은 각각 100.2 ${\pm}$ 14.5 mEq, 37.1 ${\pm}$ 7.4 mEq이었다. 소변의 나트륨/칼륨 비율은 2.8 ${\pm}$ 0.6이었다. 소변 중 나트륨 배설량과 나트륨/칼륨 비율은 실험식이 섭취기간에 유의적으로 감소하였다 (p < 0.05). 본 연구 결과 NaCl-KCl 혼합식염 식이는 나트륨의 섭취를 감소시키고 칼륨의 섭취를 증가시켜 나트륨/칼륨의 섭취비를 이상적인 수준인 1에 가깝게 변화시켜 주는 것으로 나타나 고혈압의 예방에 효과가 있을 것으로 사료된다. 특히 짠맛에 대한 기호도가 높은 우리나라 사람들에게 짠맛에 대한 기호도를 변화시키지 않고도 실제로 식생활에서 나트륨 섭취를 감소시킬 수 있는 구체적 방안을 제시할 수 있을 것으로 기대된다. 그러나 본 연구는 정상혈압을 가진 성인 여성을 대상으로 하였으므로 고혈압 환자 또는 나트륨과 관련이 있는 환자를 대상으로 한 실험이 이루어져야 할 것이다. 또한 소금 섭취가 높은 대상자들이나 나트륨의 섭취를 제한해야 하는 사람들에게 KCl을 이용한 혼합식염을 공급하여 나트륨 섭취를 감소시킴으로써 얻을 수 있는 건강증진 효과에 대한 후속 연구가 필요하다고 생각된다. 그러나 한편으로는 염화칼륨을 보충제로 과도하게 섭취할 경우 위장장애 등을 일으킬 수 있다고 알려져 있으므로 적절한 섭취량을 찾는 연구가 필요할 것이다.
