A variety of factors such as the pattern of intake (acute or chronic), monitoring interval and the characteristics of the radionuclides could have a significant influence on the estimates for the intake and internal dose. The relative differences of the assessed intakes based on the assumption of an acute intake to that of a chronic intake were evaluated by using the predicted bioassay quantity in the whole body or organs for an acute and chronic intake through the inhalation of $^{125}$ I, $^{137}$ C, $^{235}$ U with the AMAD of 1 ${\mu}{\textrm}{m}$ and 5 ${\mu}{\textrm}{m}$ for the monitoring intervals of 7, 14, 30, 60, 90, 120, 180, 360 days, respectively, The relative difference of the assessed intakes based on the intake pattern is affected by the monitoring interval, radionuclide and absorption type, but the particle size has little influence on the difference of the assessed intakes based on the intake pattern. The maximum monitoring interval, which is defined as the monitoring interval that the relative difference of the assessed intakes based on the assumption of an acute intake to that of a chronic intake is less than 10%, is 60 d for $^{125}$ I with Type F, 180 d for $^{137}$ C with Type F, 90 d for $^{235}$ U with Type M, and 360 d for $^{235}$ U with Type S. It was concluded that an intake pattern has little influence on the estimates of the assessed intake in the case where the monitoring interval is shorter than the maximum monitoring interval for each radionuclide.

The purposes of this study were to investigate the effects of the popularity of menu items in nutrient consumption of school-aged children participating in a School Breakfast Program. The weighed plate waste method was used to determine the nutrient intake of students. The nutrient intake was evaluated based on the popularity of the menu item, gender, and grades. The average intakes of all nutrients except energy, fiber, and sodium were well within the goals. Actual nutrient intake varied based upon the popularity of $entr{\acute{e}}es$ and the popularity of menu items was a main effect in nutrient content of meals. When the most popular $entr{\acute{e}}es$ were served, school-aged children's energy intake and School Breakfast Program participation rate increased. Saturated fat and sodium intakes also were higher than the goal when the most popular $entr{\acute{e}}es$ were served. The significant main effect was grades for total fat (p < 0.05) and calcium (p < 0.05), which was qualified by the two-way interaction between gender and grades for saturated fat (p < 0.05), protein (p<0.1), iron (p<0.01), vitamin C (p<0.01) and carbohydrates (p<0.001). Gender itself was not a significant main effect. Based on the findings, the suggestions for educating school-aged children on more healthful breakfast food choices and reformulating recipes for the popular $entr{\acute{e}}es$ are made.

The purpose of this study was to evaluate changes of body composition, cardio-respiratory function in ventilation threshold (VT) and maximal state exercise, systolic (SBP) and diastolic blood pressure (DBP) and serum nitric oxide (NO) production during acute reducing salt (RS) supplementation in college elite athletes. Variables of cardio-respiratory function during rest, ventilation threshold and maximal exercise was not shown a significantly difference between RS supplementation and non-supplementation, there was shown a significant increase in ventilation threshold time (p<0.05) and exhaustion time (p<0.05) during RS supplement compared to non-supplement. SBP and DBP were not shown a significant difference between RS supplement and non-supplement. This result suggests that acute intake of RS is not increased a blood pressure. Serum NO production was not significant difference in the RS supplement group, but it was shown a significantly increased levels (p<0.01, vs. recovery 30 min.) immediately after maximal exercise in the non-supplement group. This result suggests that acute intake of RS have important role in inhibition of serum NO production during maximal exercise. Conclusively, This study suggest that acute intake of RS was not influence in body composition variables, but it was positive effect in ventilation threshold time, exhaustion time, maintenance of blood pressure and inhibition of serum NO production in maximal treadmill exercise.

This study was carried out to investigate the acute changes in R-A-A system following lasix administration, and to evaluate the materials in plasma R-A-A system and electrolytic excretion every 30 minutes for 2 hours after lasix administration with normal high sodium Korean food, moderate sodium restriction, and severe sodium restriction, and it was concluded as followed; 1. Plasma renin activity, angiotensin II concentration, and aldosterone concentration elevated in course of time after lasix administration with high sodium Korean food, but the R-A-A system takes insignificant part because of the increasing rate was so slight. 2. Although the increasing rate of plasma renin activity reached lower levels, angiotensin II and aldosterone concentration were significantly increased after lasix administration with moderate sodium restriction. 3. It was observed that higher rise in aldosterone concentration following lasix administration during severe sodium restriction than when moderate sodium restriction. 4. Urinary sodium and potassium excretion during two hours after lasix administration showed decrease as little as the amount of sodium intake, but K/Na excretion ratio showed increase with small amount of sodium intake because of the decreasing rate of potassium was low value. 5. Sodium excretion after lasix administration reached more than 1.5 times of sodium intake, even though R-A-A reaction showed significantly. 6. As our results showed, R-A-A reaction following acute diuresis was insignificant with high sodium Intake, the increasing ratio of aldosterone concentration showed high rise compare with of plasma renin activity as little as the amount of sodium intake, and the participated rate in sodium reabsorption of R-A-A system was increased.

Arsenic poisoning has three types of poisoning. First, acute arsenic poisoning is usually caused by oral intake of large amount of arsenic compound with purpose of homicide or suicide. Second, chronic arsenic poisoning is caused by inhalation of arsenic in the occupational setting or by long-term oral intake of arsenic-contaminated well water. Third, arsine poisoning occurs acutely when impurities of arsenic in non-ferrous metal react with acid. Clinical manifestation of acute arsenic poisoning is mainly gastrointestinal symptoms and cardiovascular collapse. Those of chronic poisoning are skin disorder and cancer. Arsine poisoning shows massive intravascular hemolysis and hemoglobinuria with acute renal failure. Exposure evaluation is done by analysis of arsenic in urine, blood, hair and nail. Species analysis of arsenic is very important to evaluate inorganic arsenic acid and mono methyl arsenic acid (MMA) separated from dimethyl arsenic acid (DMA) and trimethyl arsenic acid (TMA) which originate from sea weed and sea food. Treatment with dimercaprol (BAL) is effective in acute arsenic poisoning only.

This research objected to the diagnosed patients as acute lymphoblastic leukemia, acute myelogenous leukemia, neuroblastoma, non-Hodgkins lymphoma, Hodgkin's disease, kidney tumor, myelodysplastic syndrom and juvenile chronic leukemia after admission in the 'P' hospital in Pusan from Aug. 1. 1999 to Jan. 31. 2000. The results of this study are summarized as follows. 1. On the specific character between the experimental(exp.) group and the control (con.) group : there were 7 of 4-7 years old patients(the most) in the experimental group(53.8％), 5 of 12 years old or older patients in the control group (38.5％). Patients who experienced operation were 7 in the exp. group(53.8％) and 6 in con. group(46.2％). The largest number of the patients' diagnosis was acute lymphoblastic leukemia by 5 in the exp. group(38.5％) and 4 in the con. group (30.8％). The hardest nausea came on the second day by 5 in the exp. group(38.5％), 9 in the con. group(69.2％). 2. P-score of the nausea vomiting on the number of daily anticancer drug administration : first day, the exp. group got 9.6 and the con. group 17.6(P = 0.03). 2nd day, 10.9 and 19.4(P = 0.00), 3rd day, 10.6 and 18.3(P = 0.00), 4th day 10.0 and 18.0, 5th day 10.9 and 16.8(P = 0.05). The score showed statistically significant difference(P < .05). 3. Oral intake didn't show statistically significant difference between two groups. However the average of Oral intake of the exp. group was continually higher than the con. group except to the first day after administration. In conclusion, nursing intervention and nutrition care are much more needed on the 2-3th day after administration to reduce nausea vomiting, and for remission of nausea and enlarging oral intake it is utilizable to apply the easy, economic Oral Cryotherapy to the young patients who undergo chemotherapy.

[Purpose] The purpose of this study was to investigate the effects of short-term creatine intake on muscle fatigue induced by resistance exercise in healthy adolescent men, i.e., lactic acid concentration and wrist and head tremor measured by an accelerometer. [Methods] Twelve healthy adolescent men who had no experience with creatine intake were included. The subjects were randomly assigned to the creatine group and the placebo group, followed by 5 days of creatine and placebo intake, and 5 times of 5 sets of leg press, leg extension, bench press, and arm curl exercises at 70% repetition maximum (RM). The lactic acid concentration before and after exercising, rate of perceived exertion (RPE), and accelerometer-based wrist tremor and head tremor during exercise were measured. Subsequently, after 7 days to allow for creatine washout, the same exercise treatment and measurement were performed in each group after switching drug and placebo between the groups. [Results] The level of lactic acid before and after the acute resistance exercise trial was significantly lower in the creatine group than in the placebo group (P <0.05). The mean RPE during the resistance exercise was significantly lower in the creatine group than in the placebo group (P <0.05). There was no difference between the two groups in the mean wrist tremor during resistance exercise, but the mean head tremor values were significantly lower in the creatine group than in the placebo group in the arm curl, the last event of the exercise trials (P <0.05). [Conclusion] Short-term creatine intake reduces the blood fatigue factor increased by resistance exercise, and is thought to suppress fatigue, especially in the latter half of resistance exercise. Therefore, these findings indicate that short-term creatine intake can have an improved effect on anaerobic exercise performance.

Objective: An experiment was conducted to investigate the effects of feed intake restriction during late pregnancy on the function, anti-oxidation capability and acute phase protein synthesis of ovine liver. Methods: Eighteen time-mated ewes with singleton fetuses were allocated to three groups: restricted group 1 (RG1, 0.18 MJ ME/kg $W^{0.75}$ d, n = 6), restricted group 2 (RG2, 0.33 MJ ME/kg $W^{0.75}$ d), n = 6) and a control group (CG, ad libitum, 0.67 MJ ME/kg $W^{0.75}$ d, n = 6). The feed restriction period was from 90 days to 140 days of pregnancy. Results: The ewe's body weight, liver weights, water, and protein content of liver in the restricted groups were reduced compared with the CG group (p<0.05), but the liver fat contents in the RG1 group were higher than those of the CG group (p<0.05). The increased hepatic collagen fibers and reticular fibers were observed in the restricted groups with the reduction of energy intake. The concentrations of nonesterified free fatty acids in the RG1 and RG2 groups were higher than those of the CG group with the reduction of energy intake (p<0.05), but there were decreased concentrations of lipoprotein lipase and hepatic lipase in both restricted groups compared with the CG group (p<0.05). In addition, the increased concentrations of ${\beta}$-hydroxybutyric acid, triglycerides, malondialdehyde, total antioxidant capacity and activities of superoxide dismutase activity and catalase were found in the RG1 group, and the concentrations of cholinesterase in the RG1 group were reduced compared with the CG group (p<0.05). For the concentrations of acute phase proteins, the C-reactive protein (CRP) in the RG1 group were reduced compared with the CG group, but there were no differences in haptoglobin relative to the controls (p>0.05). Conclusion: The fat accumulation, increased hepatic fibrosis, antioxidant imbalance and modified synthesis of acute phase proteins were induced in ewe's liver by maternal malnutrition during late pregnancy, which were detrimental for liver function to accommodate pregnancy.

A 42-year old male patient was referred to the Department of Oral Medicine, Kyungpook National University Hospital due to the chief complaint of limite mouth opening. Three years ago, the patient was diagnosed as an infarction of both cerefellar hemispheres, acute obstructive hydrocephalus and acute epidural hematoma of frontal lobe at the department of neurosurgery.Both of the infarcted cerevellar hemispheres and the epidural hematoma of frontal lobe were removed with suboccipital and frontal craniectomu. After the brain surgery jaw opening range was decreased progressively and ultimately mouth opening became almost impossible. Spasmodic and rhythmic contractions of the masseter muscles occurred intermittently during daytime as well as sleeping. Food intake was available only through Levin -tube. Actibe jaw opening exercise was prescribed with the aids of tongue blades. A moist hot pack and indomethacin phonophesis were also applied 20 minutes three times a day to decrease discomfort muscle activities. After a month of treatments, the opening range was increased to 5mm at the premolar area and oral food intake was possibel. The L-tube was removed and the patient was discharged.

The effectiveness of the extracts of Alnus japonica and Portulaca oleracea, which are effective in improving alcohol-induced liver damage, was confirmed using acute and chronic alcoholic liver injury animal models. In the acute alcoholic liver injury model, dieting Alnus japonica and Portulaca oleracea complex (ALPOC) at a dose of 50 mg/kg showed no significant change in liver or body weight, while measured plasma ALT activity to be deficient (28.12 U/ml) compared to the alcohol intake group (42.5 U/ml), and confirmed that restored it to an average level. It showed an improvement of 34.9% compared to the alcohol intake group. AST activity confirmed that it showed a very effective liver protection activity by showing a gain of 12.6%. The chronic alcoholic liver damage animal model demonstrated that ALT showed an improvement effect of 25%, and AST showed an effect similar to that of the positive control group, Hovenia extract. In addition, through H&E staining analysis, observed that the ALPOC improved the necrosis and bleeding of the liver. And the ALPOC group showed intense antioxidant activity of 127% or more compared to the alcohol intake group, and this was confirmed to have a very high activity, which is more than 20% higher than that of the hovenia fruit extract.
