The effects of extracellular pH changes on excitation-contraction coupling were studied in isolated rabbit papillary muscles. All experiments were performed in nonbicarbonate-buffered Tyrode solution, using phosphate buffer system for acidosis (pH 7.0, 6.4 or 6.0) and Tris buffer system for alkalosis (pH 7.8), which was aerated with 100% O_2 and kept at 35℃. Action potentials were measured by conventional microelectrode technique in the papillary muscles. The slow response action potentials (SRAP) were induced by superfusing the muscles to a Tyrode solution containing 27 mM KC1 and 10^-5M histamine and stimulating them with slow and intense stimuli (from 0.5 Hz, 5 V to 0.1 Hz, 20V). The results obtained were as follows; 1. Acidosis elicited a degree-dependent negative inotropic effect, whereas alkalosis induced a positive inotropig effect. The increase in isometric tension at pH 7.8 was 150%, compared to that at normal pH, but the decrease at pH 6.4 was about 50%. 2. The acidosis-induced depression of contractility was restored rapidly to normal level by the addition of Ca^2+ to the Tyrode solution or administration of agonists, histamine (10^-5M) or norepinephrine (10^-6M). 3. The parallel changes in resting membrane potential (depolarization) and overshoot, and the obvious shortening of action potential duration were observed after a change from control solution to the alkalotic Tyrode solution (pH 7.8). In acidosis (pH 7.0), however, the parallel declines in resting membrane potential (hyperpolarization) and overshoot were observed, and the duration was almost no changed. 4. SRAP, which were eliminated by Ca^2+ antagonists (verapamil or Mn^2+), were potentiated in amplitude and duration at high pH 7.8, but inhibited obviously at low pH 6.4. The results of this experiment suggest that the alteration in cardiac contractility by extracellular pH change is due to the influence upon slow inward Ca^2+ current.

김희승,윤건호,유양숙,오정아,송민선,신미옥,김경희,송복례 대한당뇨병학회 2002 임상당뇨병 Vol.3 No.1

연구배경 : 당뇨병 환자의 평균 재원기간을 단축시키고, 제한된 입원기간 내에서 질적인 면과 비용효과성을 고려한 총체적인 건강관리체계의 필요성이 요구됨으로써 생겨난 것이 당뇨병 표준진료지침(Critical Pathway: CP)이다. 현재 개발된 당뇨병 CP를 통한 진료가 환자의 당뇨병에 관한 지식을 개선시키고 이에 따라 장기적으로 당뇨병 환자의 혈당조절이 개선되었다는 과학적인 검증은 당뇨병 CP를 여러 병원에 정착시키기이전에 반드시 선행되어야 할 과제이다. 이에 본 연구는 2000년 3월부터 1년간 강남성모병원에 입원하는 당뇨병 환자를 대상으로 현재 개발된 1주일 CP를 적용한 실험군의 혈당, 당뇨병 관련 지식 및 재원일수가 대조군에 비하여 차이가 있는지를 조사하였다. 방법 : 1주일 CP를 적용한 실험군은 내과병동에 입원한 당뇨병 환자 89명이었고, 대조군은 기타병동에 입원한 당뇨병 환자 22명이었으며 CP를 적용하지 않았다. CP를 적용하기 전인 입원시에 실험군과 대조군의 공복혈당, 식후 2시간혈당, 당화혈색소 및 당뇨관련 지식을 측정하였고, 퇴원 시에 실험군과 대조군에게 공복혈당과 당뇨관련 지식을 재측정하고 재원일수를 파악하였다. 그리고 두 군에게 퇴원 3개월 후의 공복혈당, 식후 2시간 혈당 및 당화혈색소를 조사하였다. 결과 : 1) 실험군의 공복혈당은 입원 시 238.7: 1) 실험군의 공복혈당은 입원 시 238.7mg/dL에서 퇴원 시 139.4mg/dL로 감소하는 경향이었으나 퇴원 3개월 후에는 150.6mg/dL로 약간상승하는 경향을 보였다. 대조군은 입원 시 251.5mg/dL에서 퇴원 시 136.2mg/dL로 감소하는 경향이었으나, 퇴원 3개월 후에는 219.3mg/dL로 현저히 증가하는 경향이었다. 2) 실험군의 입원 시 식후 2시간 혈당은 312.5mg/dL에서 퇴원 3개월 후 248.5mg/dL로 감소하는 경향이었다. 대조군도 입원 시 식후 2시간 혈당이 300.1mg/dL에서 퇴원 3개월 후 262.5mg/dL로 감소하는 경향이었으나 실험군보다 감소의 폭이 적은 경향이었다. 3) 실험군과 대조군의 입원 시 당화혈색소는 각각 10.3%와 9.7%로 유의한 차이가 없었으나,퇴원 3개월 후 실험군은 7.5%로 대조군의 9.1% 보다 유의하게 감소하였다. 4) 실험군의 입원 시 당뇨지식 점수는 실험군이 12.1점 대조군은 12.0점으로 유의한 차이가 없었으나 퇴원 시는 실험군이 15.5점으로 대조군의 14.6점 보다 높은 경향이었다. 5) 재원일수는 실험군이 8.4일로 대조군의11.0일 보다 유의하게 적었다. 결론 : 따라서 당뇨병 환자를 위한 CP는 재원일수의 감소뿐만 아니라 환자의 자가관리에 대한 체계적인 교육과 개선의 기회를 가짐으로써 장기적인 혈당 조절의 향상을 도모할 수 있는 효과적인 방법이라고 생각한다. Background: The aim of this study was to examine the effects of the critical pathway for the admitted patients with type 2 dia betes me llitus on glycemic control, the knowledge on the disease, and the length of hospital stay. Methods: 89 diabetic in-patients were applied with the 1 week critical pathwa which was consisted of intensive education program for self-management of diabetes me llitus such as glucose monitoring, excercise prescription, diet control, self-a djustment of the drugs and so on. The results were compared with 22 diabetic inpatients who were treated with conventional way. We assessed the effects of critical pathway on the degree of glycemic control, the knowledge on the disease, and the length of hospital stay. Results: Although fasting and postprandial 2 hours blood g lucose levels did not showed sta tistically significantd ifference between critical pathway group and conventional group on discharge , HbA1c was significantly decreased in critical pathwa group compared with the conventional group (7.5±1.8% vs 9.1±2.6%) on 3 months after discharge . Knowledge on the disease tended to increase in critical pathway group compared with the conventional group on discharge. The Length of hospital stay was significantly decreased in critical pathway group compared with the conventional group (8.4±2.8day vs 11.0±3.9da ) Conclusion: These results showed that critical pathway for the patients with diabetes mellitus might be a usefulway for improving the long term glycemic control through motivation, enhancing the knowledge on the disase as well as reducing the length of hospital stay.

The purpose of this study was to evaluate the effect of concentration and pH of lactic acid on the formation of artificial root caries lesions formation in bovine teeth. The characterictics of artificially produced early root lesions were observed with polarized light microscope and the depth of lesions were mearsured with measuring microscope The results were as follows: 1. In the group of low pH and high concentration of lactic acid, the progress of lesion formation was faster than that of high pH and low concentration lactic acid group. 2. In the same group, initial lesion progress faster, but progression rate was reduced as time goes by. 3. In the development of initial root caries, cementum was act as a barrier to protect dentin from lesion progression.

The purpose of this study was to estimate change of leukocyte subsets on the increased maximal exercise load during the time of exercise intensity and after all-out and recovery. On a sample of 14 male collegiate students they were subdivided into two group(7 athletes group, 7 normal students group). Number of leukocytes increased from rest through All-out exercise intensity and decreased at recovery. Resting levels were again reached after 60 mins of recovery. There were no significant differences between groups. The rate of increase was significantly higher(p<.01) for the athlete group during 40%, 60%, 80%and All-out and exercise intensities. Percent of neutrophils decreased for both groups until All-out time, but the absolute number of neutrophils increased at each level of exercise intensity and reached maximum level during All-out time. There were no statistically significant differeneces between two groups for the percent and absolute number of neutrophils. The rate of increase was significantly higer (p<.05) for the athlete group at 80% exercise intensity. Percent and absolute number of lymphocytes increased from rest to All-out time but decreased at recovery. Although there was no difference for the rate of increase between the two groups, absolute number of lymphocytes was significantly higher(p<.05) for the athlete group from 40% to All-out exercise intensity. Based on those results mentioned above, the follwing conclusion can be reach: Absolute number and percent of leukocyte subsets changes during graded maximal exercise. Specifically absolute number of leukocyte subsets increased from rest to all-out exercise.

Purpose: The purpose of this study was to develop an eye care protocol for intensive care unit (ICU) patients. Method: A systematic review was conducted to develop an eye care protocol for ICU patients. Searches were performed using computerized databases (CINAHL, MEDLINE, EBM Review) and citation search from 1996 to January 2007. For the keywords, "eye care", and "randomized controlled trial" were used to identify experimental studies regarding eye care for ICU patients. After reviewing the collected studies, a preliminary eye care protocol algorithm was created. Then, content validity was examined with ophthalmologists and ICU nurses. Results: Six studies were included to serve as a basis for framing of the preliminary algorithm. The final eye care protocol was completed after verifying the preliminary algorithm's content validity. The final eye care protocol was organized in the following manner: 3 items in the assessment stage, 7 items in the no-risk stage, 4 items in the low-risk stage, and 5 items in the high-risk stage. Conclusion: The results indicate that, for leu patients, nurses can broaden their knowledge regarding ocular diseases, as well as improve their practice-based eye care nursing performance.
