초록
Ethanol 투여(投與) 용량(容量)에 따른 혈압(血壓)과 신기능(腎機能)의 변화(變化)를 알아보고자 흰쥐의 복부대동맥(腹部大動脈)에 catheter 를 삽입(揷入)하고 그 다른 끝을 목뒤로 끌어낸 후(後) 1주일(週日)이상 수술(手術)에서 회복(恢復)시킨 다음 실험(實驗)에 사용(使用)하였다. 실험직전(實驗直前)에 방광(膀胱)을 비운 뒤 metabolism cage에 넣어 안정(安靜)시킨 후(後) 60분(分)에 복부대동맥(腹部大動脈)의 catheter를 통(通)하여 평균동맥혈압(平均動脈血壓)(MAP)을 직접(直接) 측정(測定)하고 동맥혈액(動脈血液)과 뇨(尿)를 채취(採取)하였다. 곧 이어 ethanol 은 10 g% (저농도(低濃度)), 또는 30 g% (고농도(高濃度)) 용액(溶液)을, 대조실험(對照實驗)으로는 물을, 체중(體重) 100 g 당(當) 1 ml 씩 각각(各各) 경구(經口) 투여(投與)하였다. 용액투여후(溶液投與後) 3시간(時間)동안 MAP를 측정(測定)하고, 혈액(血液)은 매(每) 시간(時間)마다, 뇨(尿)는 90분(分) 간격(間隔)으로 채취(採取)하여 다음의 결과(結果)를 얻었다. 혈중(血中) ethanol 농도(濃度)는 ethanol 투여후(投與後) 1시간(時間)에 최고치(最高値)를 나타내고 (저농도(低濃度);
In order to determine the dose-response relationship of ethanol on blood pressure and renal function, 2 doses of ethanol were intubated into albino rats. For a direct measurement of arterial blood pressure, a polyethylene catheter(PE 10) was implanted in the abdominal aorta, and the other end of the catheter was pulled out of the back of the neck. The experiment was conducted after the rats recovered from the surgery. After emptying their bladders, the rats were placed in a metabolism cage. Mean arterial pressure (MAP) was measured and arterial blood samples were collected through the catheter. Following the collection of the control urine sample, 1 ml of 10 g% (low dose), or 30 g% (high dose) of ethanol/100 g BW was intubated. 1 ml of water/100 g BW was intubated into the control group. MAP and blood samples were taken every hour, and urine samples were collected every 90 min for 3 hours. Blood alcohol concentrations reached a peak at 1 hour (low dose:
