Purpose: The study examined the effects of preoperative patient controlled analgesia (PCA) education on postoperative pain, knowledge of PCA, and attitude toward pain medication. Methods: The participants were patients who underwent surgery in H University Hospital,and were assigned to PCA group (experiment group, n=30) or the control group (n=30). Results: Knowledge of PCA and positive attitude toward pain medication were higher in the experiment group than in the control group. Postoperative pain scores in the experiment group were significantly lower than those in the control group at 48 and 72 hr after surgery, but there was no significant difference at 24 hr after surgery. The experiment group had more positive attitudes on the medication than the control group. Conclusions: Preoperative PCA education could be an effective nursing intervention for pain management of patients after surgery.

Purpose : The purpose of this study was to evaluate the effects of back muscle stretching on the flexibility of spinal column. Methods : The subjects were consisted of healthy adults (18 of females, 22 males ; mean aged 21.83) from 18 to 29. All subjects randomly assigned to the control group, back muscle stretching group. back muscle stretching group received back muscles stretching for 20 minutes per day and 3 times a week during 3 week period. Spine motion analyzer (Spinal Mouse) was used to measure the flexibility of spinal column. All measurement of each subjects were measured at pre-experiment, after 10 days, and after 21 days. Results : The results of this study were summarized below 1. The sacral tilt angle of the hip joint of control group, back muscle stretching group was no significantly differences at pre-experiment and after 10 days(p>0.5), but differency of each group occurred at after 21 days(p<0.5). the sacral tilt angle significantly increased at the back muscle stretching group rather than the control group. 2. The thoracic vertebral tilt angle of the control group, back muscle stretching group was no significantly differences at pre-experiment, after 10 days, after 21 days(p>0.5). 3. The lumbar vertebral tilt angle of the control group, back muscle stretching group was no significantly differences at pre-experiment, after 10 days, after 21 days(p>0.5). 4. The spinal tilt angle of control group, back muscle stretching group was no significantly differences at pre-experiment and after 10 days(p>0.5), but differency of each group occurred at after 21 days(p<0.5). the spinal tilt angle significantly increased at the back muscle stretching group rather than the control group(p>0.5). 5. The length of the spinal column of control group, back muscle stretching group was no significantly differences at pre-experiment and after 10 days (p>0.5), but differency of each group occurred at after 21 days(p<0.5). the length of the spinal column significantly increased at the back muscle stretching group rather than the control group(p<0.5). Conclusion : These data suggests that 3-week back muscle stretching improved the flexibility of sacrum, spinal column, and also improved spinal column lengthening.

Objectives: This experiment was conducted to verify the effects of Chungganhaeju-tang(Qingganjiejiu-tang) on the alcohol metabolism and liver functions, by measuring the activity levels of ADH and ALDH, as well as glucose, triglyceride, and BUN. Damage of the liver cells caused by alcohol was determined through the examination of serum levels of AST, ALT, ALP, LDH, and uric acid. Methods: Sprague-Dawley rats were used in this experiment and the rats were divided into control and experiment groups. Chungganhaeju-tang(Qingganjiejiu-tang) extract was orally administered in the experiment group for three weeks. Each group was further classified into two sub-groups, and control group's blood was taken without oral ingestion of alcohol, while the experiment group' s blood was withdrawn after ingestion of alcohol. Evaluation of damage level was done considering the presence of extract and alcohol. Results: In this experiment, Chungganhaeju-tang(Qingganjiejiu-tang) significantly suppressed the activity of ADH which is a precursor enzyme of acetaldehyde, but didn't cause significant changes in the activity of ALDH which is a catabolic enzyme. Decreased glucose level due to alcohol consumption was recovered back to the normal level and increased levels of triglyceride, BUN, AST, ALT, ALP, LDH, and uric acid were significantly reduced. Conclusions: These experiment results suggest that Chungganhaeju-tang(Qingganjiejiu-tang) inhibits the formation of acetaldehyde in the metabolism of alcohol, and affects the recovery of weakened liver functions due to alcohol.
