Hyponatremia, the most common electrolyte disorder, has been rarely reported as causing rhabdomyolysis. Osmotic demyelination syndrome (ODS), a demyelinating disease of the central pons and/or other areas of the brain, is infrequently reported as associated with rapid correction of hyponatremia. This paper reports a case of ODS after correction of severe hyponatremia complicated by rhabdomyolysis. A 47-year-old female with a history of chronic alcoholism presented herself at the hospital with altered consciousness after three days of nausea and vomiting. She was on a thiazide diuretic for essential hypertension. Her blood tests upon her hospital admission showed hyponatremia ($Na^+$ 98 mEq/L), hypokalemia ($K^+$ 3.0 mEq/L), and elevation of her serum creatine phosphokinase (3,370 IU/L) with an increase in her serum myoglobin level 11,267 ng/mL). She was treated with intravenous fluid therapy that included isotonic and hypertonic salines along with potassium chloride. She became more alert, and her neurological condition gradually improved after the first five days of her therapy. On the ninth day after her admission, she developed progressive quadiaresis associated with dysarthria, dysphagia, and dystonia despite the resolution of her hyponatremia. Magnetic resonance imaging of her brain on 16th day revealed symmetrical areas of signal hyperintensity in her central pons, basal ganglia, and precentral gyrus in T2-weighted images, which are consistent with ODS. Her neurological symptoms steadily improved after six weeks with only supportive treatment and rehabilitation.

Cadmium (Cd) is well known as a spermatotoxic and gonadotoxic heavy metal ion. This study was performed to assess the possible protective effect of Enerbalance on Cd-induced spermiotoxicity and testicular damage. The control group received isotonic saline; Cd group received Cd (2 mg/kg BW per day) orally; extract-treated groups were orally administrated with Enerbalance (50 mg and 100 mg/kg BW per day) and Cd for 10 days. Morphological changes of testicular tissue, sperm characteristics, oxidative/antioxidative parameters from testis, and serum sexual hormone level were determined. Enerbalance was significantely increased sperm amount in cauda epididymis without changes of ratio of epididymis/body weight and testis/body weight. Cd caused a marked decrease in epididymal sperm concentration and chemotactic sperm motility, testicular superoxide dismutase (SOD), catalase (CAT), Enerbalance was significantly ameliorated loss of epididymal sperm concentration, sperm chemotactic motility, antioxidative parameters, and male hormone whereas decreased abnormal architecture by testis damage. Enerbalance was successfully attenuated these adverse effects of Cd and offers a dose-dependent protection. Our study demonstrated that Enerbalance could proffer a measure of protection against Cd-induced testicular damage and spermiotoxicity by possibly reducing oxidative stress and increasing the antioxidant defense mechanism in mice.
The purpose of this study was to identify the effectiveness of a nutrition education program of reducing children's sugar intake based on social cognitive theory. This education program composed of 6 units was conducted in discretional activity class of the $3^{rd}$ and $4^{th}$ grade elementary school students. The results are as follows: First, the rate of correct answers and score of nutrition knowledge significantly increased after nutrition education. The scores of nutrition education in male students, students whose mothers have no job, and students with skinny physiques were much improved after nutrition education(p<0.05, p<0.01, p<0.001, respectively). Second, the dietary attitudes toward reducing sugar intake and checking nutrition labels significantly improved(p<0.05). And also, it tended to decrease in preference and intake of sweet foods. Third, the consumption of candy caramel jelly(p<0.05), yogurt(p<0.05), jam honey(p<0.05), and ice cream(p<0.001) were reduced after nutrition education. Besides, obese students' consumption of isotonic beverages, carbonated beverages, and fruit juice was reduced. Therefore, a positive change in dietary behavior appeared. Based on the above results, we confirmed that the nutrition education program focusing on reducing sugar intake applied with social cognitive theory was effective for improving the nutrition knowledge, dietary attitude and dietary behavior in sugar intake in elementary school students. Especially, this program showed the improvement in nutrition knowledge as well as dietary attitude and behavior in sugar intake among obese children. Since nutrition education during childhood significantly influences lifetime-health and disease prevention, it is necessary to develop theory-based nutrition education program and practice systematic and constant nutrition education in elementary schools.

The purpose of this study was to identify the difference and correlation in elbow joint maximal flexion strength according to measurement methods and characteristics of muscular contraction, and to develop the predictive equation of elbow joint maximal flexion strength for the optimal exercise intensity setting and accurate measurement. Subjects were 30 male university students. Elbow joint maximal flexion strength of isokinetic contraction, isometric contraction at $75^{\circ}$ elbow joint flexion position, isotonic concentric 1RM, manual muscle strength (MMT) were measured with isokinetic dynamometer, dumbbell, and manual muscle tester. Pearson's r, linear regression equation, and multiple regression equation between variables were calculated. As a result, the highest value was isometric contraction. The second highest value was MMT. The third highest value was isokinetic contraction. 1RM was the lowest. Predictive equations of elbow joint maximal flexion strength between isometric and isokinetic contraction, between isometric contraction and 1RM, among isometric contraction, 1RM, and body weight were developed. In conclusion, 1RM and isokinetic elbow joint maximal flexion strength could be seemed to underestimate the practical elbow joint maximal flexion strength. And it is suggested that the developed predictive equations in this study should be useful in criteria- and goal-setting for resistant exercise and sports rehabilitation after elbow joint injury.
Purpose: This study examined changes in gait speed and stride length after an intervention involving simultaneous scapular and pelvic patterns of proprioceptive neuromuscular facilitation in a hemiplegic patient. Methods: A 58-year-old woman with left hemiplegia who had complained of slowness of gait speed and weakness of leg strength took part in an intervention involving scapular postdepression patterns on the affected side and pelvic postdepression patterns on the nonaffected side. The intervention was performed with the patient lying on her left side, in a half kneeling position, and in a standing posture. Rhythmic initiation was used for teaching the movements to the patient and improvement of kinesthesia, and a combination of isotonic was employed for increasing strength and irradiation of the scapula and pelvic movement. The intervention took place for 30 min. It was implemented twice a day, 5 days a week, for 3 weeks. After three repetitions, the average time taken to complete the 10-m walk test (10 MWT), in addition to stride length, was measured to determine gait speed. Results: After the 3-week program, the patient's performance in the 10 MWT improved from 21.7sec to 17.1sec, and her stride length improved from 31.4cm to 38.7cm. Conclusion: The results showed that trunk movement exercise, especially coordinative movements of the scapula and pelvis can improve gait speed and stride length by increasing trunk stability and mobility. A combination of pelvic and scapular patterns can facilitate trunk rotation, thereby improving gait speed and stride length.
Fungal cell walls and cell membranes are the main targets of antifungals. In this study, we report on the antifungal activity of an ethanol extract from Paeonia lactiflora against Candida albicans, showing that the antifungal activity is associated with the synergistic actions of preventing cell wall synthesis, enabling membrane depolarization, and compromising permeability. First, it was shown that the ethanol extract from P. lactiflora was involved in damaging the integrity of cell walls in C. albicans. In isotonic media, cell bursts of C. albicans by the P. lactiflora ethanol extract could be restored, and the minimum inhibitory concentration (MIC) of the P. lactiflora ethanol extract against C. albicans cells increased 4-fold. In addition, synthesis of $(1,3)-{\beta}-{\small{D}}-glucan$ polymer was inhibited by 87% and 83% following treatment of C. albicans microsomes with the P. lactiflora ethanol extract at their $1{\times}MIC$ and $2{\times}MIC$, respectively. Second, the ethanol extract from P. lactiflora influenced the function of C. albicans cell membranes. C. albicans cells treated with the P. lactiflora ethanol extract formed red aggregates by staining with a membrane-impermeable dye, propidium iodide. Membrane depolarization manifested as increased fluorescence intensity by staining P. lactiflora-treated C. albicans cells with a membrane-potential marker, $DiBAC_4(3)$ ((bis-1,3-dibutylbarbituric acid) trimethine oxonol). Membrane permeability was assessed by crystal violet assay, and C. albicans cells treated with the P. lactiflora ethanol extract exhibited significant uptake of crystal violet in a concentration-dependent manner. The findings suggest that P. lactiflora ethanol extract is a viable and effective candidate for the development of new antifungal agents to treat Candida-associated diseases.
Pulmonary alveolar proteinosis is characterized by the accumulation of PAS positive lipoproteinaceous or amorphous proteinaceous material in the alveolar space with spared delicate septal architecture of the lung interstitium and impaired gas exchange of alveoli. We experienced a case of secondary pulmonary alveolar proteinosis in a 41 year old male patient who have occupational history of engagement as a mason over 4year. He compalined exertional dyspnea and chest discomfort, and presented fine inspiratory crackle at both lower lung field, numerous fine nodular denisties in both lung field with peripheral sparing. Light microscopic finding of lung tissue obtained by transbronchiallung biopsy revealed homogenous eosinophilic colloid-like luminal content in the alveolar space, and electron microscopy of bronchoalveolar lavage fluid concentrate showed electron-dense multilamellated structures. To treat the disease, we tried whole lung lavage of right lung with isotonic saline under general anesthesia. After whole lung lavage of right lung, he showed markid improvement of symptom and partial improvement of chest X-ray findings. The patient has been followed for 12 month until now, with no evidence of aggravation.
Objectives: This study was carried out to analyze the single-dose toxicity of ShinYangHur (SYH) herbal acupuncture injected into the muscles of Sprague-Dawley (SD) rats. Methods: The SYH herbal acupuncture was made in a clean room at the Korean Pharmacopuncture Institute (KPI, Korea-Good Manufacturing Practice, K-GMP). After the mixing process with sterile distilled water, the pH was controlled to between 7.0 and 7.5. Then, NaCl was added to make a 0.9% isotonic solution by using sterilized equipment. All experiments were conducted at Biotoxtech, an institution authorized to perform non clinical studies under the regulations of Good Laboratory Practice (GLP). SD rats were chosen for the pilot study. Doses of SYH herbal acupuncture, 0.25, 0.5, and 1.0 mL, were administered to the experimental groups, and a dose of normal saline solution, 1.0 mL, was administered to the control group. This study was conducted under the approval of the Institutional Animal Ethics Committee. Results: No deaths or abnormalities occurred in any of the four groups. No significant changes in weight, hematological parameters or clinical chemistry between the control group and the experimental groups were observed. To check for abnormalities in organs and tissues, we used microscopy was used to examine representative histological sections of each specified organ; the results showed no significant differences in any of the organs or tissues. Conclusion: The above outcomes suggest that treatment with SYH herbal acupuncture is relatively safe. Further studies on this subject are needed to yield more concrete evidence.
This study investigated the influences of the beverage intake on food behavior and personality for 1295 adolescents. The results were as follows. The favorite beverage was 'fruit juice', and preference of 'coffee' was the lowest. 'Milk and dairy product' was highest and 'milkshake' was lowest in intake frequency of beverage. The preference correlated positively(r = 0.391) with the intake frequency of beverage, especially high in 'green tea and black tea'(r = 0.622), 'coffee'(r = 0.581), 'carbonated drink'(r = 0.538), and 'milk and dairy product'(r = 0.501). The explanation power(R2) of beverage preference on beverage intake was 0.153. The explanation power($R^2$) of beverage intake on food behavior was 0.127, and 'carbonated drink' and 'coffee' as well as 'milkshake' had a negative influence on food behavior: however, 'milk and dairy product', 'green tea and black tea', and 'fruit juice' had a positive influence on food behavior. The relationship of beverage intake and sociality was very low($R^2$= 0.013), and 'isotonic drink' and 'green tea and black tea' had a positive influence on sociality. The relationship between beverage intake and anger expression was also very low. 'Coffee' showed a positive relationship with anger-in. 'Carbonated drink' and 'milkshake' showed a positive result with anger-out. 'Milkshake' showed a negative relation with anger-control, but 'green tea and black tea' and 'milk and dairy product' showed a positive relation. From these results, it was necessary to develop the practical nutritioneducation program on proper beverage choice for adolescents leading to better metal and physical status.
The effect of calcitonin gene-related peptide (CGRP), substance P (SP) and electrical stimulation of the tooth on the intradental nerve activtiy (INA) was investigated in anesthetized cats. The INA was recorded from single pulp nerve units dissected from the inferior alveolar nerve under stereomicroscope. The INA elicited by 3 minute application of 4M NaCl in deep dentinal cavity was compared before and after stimulation at 10 minute intervals. The magnitude of INA was calculated as the total number of nerve impulses produced in given period, and the changes of INA are expressed as % of control INA. The results obtained were as follows. 1. 16 single pulp nerve units were classified as 14 $A{\delta}$-fibers (3.4~19.4m/sec) and 2-fibers (1.5~1.7m/sec) according to the conduction velocity. 2. 4M NaCl evoked an irregular bursts of spikes which continued until washing out. Isotonic saline did not affect INA to subsequent applications of the hypertonic NaCl solution (P>0.05). 3. Local application of CGRP ($200{\mu}g$/ml) in deep dentinal cavity reduced the INA induced by 4M NaCl in $A{\delta}$-fiber units (P<0.01) and some units of those responded to CGRP during application. 4. Local application of SP ($100{\mu}g$/ml) in deep dentinal cavity reduced the INA induced by 4M NaCl in AS-fiber units (p<0.05), but increased the INA in C-fiber unit coincided with large reduction of the INA of $A{\delta}$-fiber units. 5. Monopolar electrical stimulation applied to the crown at intensities high enough to excite C-fibers (12V, 5ms, 10Hz, 10~30min) decreased the INA in $A{\delta}$-fiber units (P<0.01) and systemic pretreatment with phenoxybenzamine (3mg/kg, i.v.) enhanced this inhibitory effect (P<0.01). On the contrary, electrical stimulation increased the INA in C-fiber unit.
