Nitric oxide (NO) has been known to function as a cellular signaling messenger in various tissues and organs. The present study was aimed to investigate whether the regulatory mechanisms of calcium influx are mediated by the endogenous NO in submaxillary acinar cells. Effects of agents which stimulate or inhibit the NO-cGMP pathway on the calcium influx and potassium efflux were examined in submaxillary cells of the rat in vitro. 1) In the submandibular slices, carbachol (10^-5 mol/L) increased the NO_2 contents, which was prevented by pretreatment with L-NAME. 2) In the submandibular slices, K^+ efflux in response to carbachol (10^-5 mol/L) was significantly inhibited by pretreatment with L-NAME (10^-4 mol/L) which was attenuated by L-arginine (10^-5 mol/L). 3) L-NAME (10^-4 mol/L) did not affect the transient K^+ efflux in response to carbachol (10^-5 mol/L), but decreased the sustained K^+ efflux. 4) In the isolated submandibular acini, calcium influx by carbachol (10^-5 mol/L) was reduced by L-NAME or L-NMA. 5) In the isolated submandibular acini, calcium influx induced by sodium nitroprusside (10^-6 mol/L) was attenuated by pretreatment with hemoglobin (10^-4 mol/L) or methylene blue (10^-4 mol/L). 6) Calcium influx by 8-Br-cGMP (10^-4 mol/L) was inhibited by H8, (10^-4 mol/L). 7) Calcium influx by 8-Br-cGMP was not affected by nifedipine or verapamil (10^-5 mol/L) but was slightly decreased by reduction of extracellular sodium concentration. These results suggest that endogenous NO stimulates Ca^2+ influx through activating a cGMP-dependent protein kinase-activated nonselective cation channel in submandibular acinar cells.

A Continuous Uniform Feeding method is studied with a modified table feeder. The table feeder examined has either two or three scrapers. Powders used in the experiment are talc, calcium carbonate, and quartzsand covering a wide range of flow ability. Precision of feeding is tested with particular attention to characteristics of the feeder and properties of powders discharged. Furthermore, with respect to testing methods of feeder, the effect of characteristics of the feeder and properties of powders discharged on the precision is studied both experimentally and theoretically. As a result, variation of precision with characteristics of the feeder and properties of powders discharged becomes clear even when the powder flow rate has a periodic fluctuation.

「양부 고민 해결담」에 나타난 '속 이야기'에 의한 문제 해결적 말하기 방식

If education intends to bring up adaptable people, it should focus on developing the ability of solving problems. The curriculum of the department of Korean education shows the importance of problem-solving ability in teaching mother tongue. This thesis will inquire into the problem-solving way of speaking in the Story of Solving Stepfather's Problem* by analyzing speaker's 'story in story.' The procedures are as follows: To begin with, grasp the essence of the problem. Then explain the characteristics of the performance-arena in 'story in story.' After that look into the function of 'story in story' in the context of solving problems. In that story, the stepfather has a problem with his son's natural father. The natural father asserts that the son is his. He insists on the ideology that the paternal line takes precedence of maternal line. Because the stepfather regards the ideology as right, he is torn between keeping his son and sending him back to the natural father. To solve his stepfather's problem, the sun emphasizes the importance of 'love and devotion' instead of 'the paternal line' in the relationship of father to son. But it is difficult to convince people of the new ideology in direct way. So the performance-arena-the banquet and the encounter-is created. There are many people in the banquet and court. The king stands for the official event, and the natural father is the person concerned. So the result holds in all cases. By the way, 'the story of seeds and fields' asks for the listener's decision. That story features the trivial matters and common things in life the importance of love and devotion. By performing this story, the speaker let the listener make his own decision, and that the speaker finds some common ground as a basis for his opinion. Therefore, performing the story which is similar to one's own problem can be regarded as a way of persuading the other party.

The dust collection efficiency and pressure loss of a cyclone type air cleaner (Multi microcyclone described in this report) as applied to a four-cylinder four-stroke internal combustion engine and the effect of this aircleaner on the volumetric efficiency of the engine were researched in a series of engine motoring tests. The test results were compared with those obtained in a series of tests by using a blower. The performances of a paper filter were also tested by the same methods. The experimental results are summarized as follows; In the engine test, the dust collection efficiency of the multi microcyclone was about 98% at 3,500 r.p.m. and about 96% at 700 r.p.m. The efficiency of the paper filter was 98~99% at low speed but decreased to 86% at 3,500.r.p.m of engine. The multi micro-cyclone had a little air flow resistance. The test engine with the above cyclone showed rather a higher volumetric efficiency by about 8% than one without any air cleaner at the engine speed of the maximum volumetric efficiency.

Narcotic analgesics has been known as representitive drugs for pain control n terminally ill patient with palliative care, narcotic analgesics use is most effective and best, way to reduce pain in that patients However many patients are poorly complient with narcotic analgesics for lack of knowledgement of narcotics effect, perception of addictive drug, tolerence and adverse reaction. In addition to many doctors do not choose the adequate narcotics according to pain severity. It has been reported that effective pain management has not been achieved by doctors and nurses because of shortness of knowledgement of narcotic use on administration. This study was performed to identify pharmacist knowledgement of narcotic analgesics in respect that the pharmacist are responsible for patient education of narcotic medication, to identify the barrjers of narcotic dispensing and administration and then to compare the knowledgement between doctors, nurses and pharmacist. At first we surveyed the pharmacist's knowledgement and attitude by written questionnaire in SNUH in Sep. 2000, and then we compared this result and doctors and nurses' result has been taken already in SNUH in May 1999. The questionnaires are composed of narcotics classification 11, narcotic pharmacology 8, narcotic administration 5, more detail question 15 cited in Elliot study. The result is analysed by average, S.D., frequency, percentile, comparison of knowledgement of doctors, nurses and pharmacist is analysed by paire t-test, ANOVA. As a result, the pharmacist group has higher average in knowledgement of narcotic analgesics, however it was not different from doctor and nurse's significantly. According to result of attitude analysis, 48% of pharmacist has been hesitated in dispensing and administration of narcotics, that was because of the difficulty in management of narcotic prescription (25%). The role of pharmacist in pain management of patients who take narcotic analgesics is very important and great. We ought to obtain a certain of accurate knowledgement of narcotic analgesic use and perform a effective and responsible medication education and counseling.

The purpose of this study was to identify hindlimb muscle atrophy in stroke induced rat and determine the effect of endurance exercise on body weight, weight of hindlimb muscle during 7 days after stroke induction. Thirty four male Sprague-Dawley rats with 200-270g body weight were divided into four groups : control, control+exercise(Con+Ex), stroke, and exercise after stroke(St+Ex) group. The control group and Con+Ex group received sham operation and the stroke group and St+Ex group received right MCA occlusion operation by using silicon-coated probe. The Con+Ex and St+Ex groups ran on a treadmill for 20min/day at 10m/min and 10 "grade. Daily body weight and diet intake were measured every morning for 7 days. Cerebral infarction of stroke and St+Ex groups were identified by staining with TCC for 30minutes. The data were analyzed by Kruskd-Wallis test and Mann-Whitney U test using the SPSSWIN 9.0 program. Body weight of the control group at the 7th day increased by 18.3% significantly from the first day of experiment, that of the stroke group at the 7th day decreased by 6.7% significantly compared to the day of receiving right MCA occlusion operation. Body weight of the Con+Ex group at the 7th day increased by 10.3% significantly from the first day of experiment, that of St+Ex group at the 7th day also increased by 13.4% significantly compared to the day of receiving right MCA occlusion operarion. The total amount of diet in stroke group decreased significantly compared to that of St+Ex and that of control group. In stroke group the wet weight of both sides of soleus, plantaris, and gastrocnemius muscles decreased significantly compared to that of control group. The relative weight of affected(left) plantaris and gastrocnemius muscles decreased significantly compared to that of the control group. The difference between the weight of affected and unaffected soleus, plantaris, and gastrocnemius muscles were not significant in stroke group. The wet weight of right gastrocnemius muscles in Con+Ex group increased compared to that of control group. The relative weight of right gastrocnemius muscle increased significantly compared to that of the control group. The wet weight of St+Ex group increased significantly compared to that of the stroke group in both sides of soleus, plantaris, and gastrocnemius muscles. The relative weight of affected plantaris muscle increased significantly compared to that of the stroke group. The difference between the weight of affected and unaffected soleus, plantaris, and gastrocnemius muscles were not significant in St+Ex group. Body weight and wet weight of soleus, plantaris, and gastrocnemius muscles in the St+Ex group did not recover to the values of control group. Based on these results, it can be suggested that endurance exercise during acute stage of stroke can reduce muscle atrophv related to denervation. inactivity and undernutrition.
