Burn patients basically go through the sequential stages of physiological, psychological and social emergency after the burn injury. In the present study, 88 burn patients were classified into three groups according to the stages as mentioned above. Then, we observed the states of anxiety, depression, inward activities, various psychological responses measured by SCL-90-R, and body image changes in each stage. The study results were as follows: 1) We found that depressive symptoms increased as the stage advanced. They were correlated with family conflicts and low level of education. The state of anxiety was not correlated with the staging. 2) There were differences between stages I and III in ANX, DEP, SOM, PHOB axes of SCL-90-R. 3) The mood of burn patients and the patients' cooperation to the treatment observed by the nurse was partially correlated with depression and anxiety, while the patients' relation to others and interpersonal relationship were not. 4) Variables such as the size of burned area, duration of hospitalization and darkening skin affected the patients' body image. 5) We found that burn patients have psychological difficulties. Therefore, the treatment of burn injury should be done in parallel with the psychological treatment by professionals.

BACKGROUND: Acute myocardial infarction is one of major cardiovascular disease that increases according to the changes of diet and life style. Early diagnosis and treatment of acute myocardial infarction is critical for better prognosis and for reducing mortality. But early diagnosis of acute myocardial infarction is limited by several factors. Recently it was reported that measurements of several serum cardiac enzymes were useful for early diagnosis of acute mocardial infarction. This study was performed to investigate which method of serum creatine kinase measurement is the faster and accurate and whether serum creatine kinase is an early noninvasive predictor of coronary artery patency following thrombolysis in patients with acute myocardial infarction by means of analysis of serial changes in serum creatine kinase. METHODS: This study included 32 patients who had acute myocardial infarction. Serum CK-MB was measured by electrophoretic method and enzymatic immuoasssay method. and compared with EKG and total CK activity which measured by photoabsorbance method. Also we studied whether CK time-activity could be predictor for reperfusion. RESULTS: Immunoassay method accurately measures the serum CK-MB and correlates well with that of electrophoretic method in patients with acute mocardial infarction. Immunoassay method is more sensitive than EKG and has the similar sensitivity to electrophoretic method in diagnosis of acute myoardial infarction. Reperfusion of an occluded coronary artery results in early elevation of serum creatine kinase and CK-MB reflected by earlier appearance time, peak, and onset of clearance. CONCLUSION: Because immunoassay measurement of serum creatine kinase is faster than electrophoresis and requires less technical expertise, it is possible to make diagnosis in patients with acute myocardial infarction in a more timely and cost effective manner and creatine kinase is good predictor of recanalization of an occluded coronary artery after intravenous thrombolytic therapy.

Sinomenium acutum has been long used in the preparations of traditional medicine in Japan, China and Korea for the treatment of various disorders including rheumatism, fever, pulmonary diseases and mood disorders. Recently, it was reported that Sinomenium acutum, has sedative and anxiolytic effects mediated by GABA-ergic systems. These experiments were performed to investigate whether sinomenine (SIN), an alkaloid derived from Sinomenium acutum enhances pentobarbital-induced sleep via γ-aminobutyric acid (GABA)-ergic systems, and modulates sleep architecture in mice. Oral administration of SIN (40 mg/kg) markedly reduced spontaneous locomotor activity, similar to diazepam (a benzodiazepine agonist) in mice. SIN shortened sleep latency, and increased total sleep time in a dose-dependent manner when co-administrated with pentobarbital (42 mg/kg, i.p.). SIN also increased the number of sleeping mice and total sleep time by concomitant administration with the sub-hypnotic dosage of pentobarbital (28 mg/kg, i.p.). SIN reduced the number of sleep-wake cycles, and increased total sleep time and non-rapid eye movement (NREM) sleep. In addition, SIN also increased chloride influx in the primary cultured hypothalamic neuronal cells. Furthermore, protein overexpression of glutamic acid decarboxylase (GAD(65/67)) and GABA(A) receptor subunits by western blot were found, being activated by SIN. In conclusion, SIN augments pentobarbital-induced sleeping behaviors through GABA(A)-ergic systems, and increased NREM sleep. It could be a candidate for the treatment of insomnia.

Rhynchophylline (RP) is a major tetracyclic oxindole alkaloid of Uncariae Ramulus et Uncus which has been used to treat hypertension, seizures, pain and anxiety in the oriental countries. A recent report revealed that RP attenuated ischemia-induced neuronal damage and kainite-induced convulsions in animals. This study was performed to investigate whether RP enhances pentobarbital-induced sleep behaviors and modulates sleep architecture in mice. Locomotor activity was significantly inhibited by RP at 0.25 and 0.5 mg/kg, similar to 2 mg/kg diazepam (a benzodiazepine agonist) in mice. RP shortened sleep latency and increased total sleep time in a dose-dependent manner when administrated with pentobarbital (42 mg/kg, i.p.). RP also increased the number of sleeping mice and total sleep time by concomitant administration with the sub-hypnotic dosage of pentobarbital (28mg/kg, i.p.). On the other hand, RP (0.25mg/kg, p.o.) itself significantly inhibited sleep-wake cycles, prolonged total sleep time, and rapid eye movement in rats. In addition, RP also increased chloride influx in the primary cultured hypothalamic neuronal cells. In addition, we found that glutamic acid decarboxylase (GAD(65/67)) was activated by RP. In conclusion, RP augments pentobarbital-induced sleeping behaviors, and can be a candidate for treating insomnia.

BACKGROUND: Interest in pharmacist participation in the multidisciplinary intensive care team is increasing. However, studies examining pharmacist interventions in the medical intensive care unit (MICU) are limited in Korea. The aim of this study was to describe the current status of pharmacist interventions and to identify common pharmacologic problems requiring pharmacist intervention in the MICU. METHODS: Between September 2013 and August 2014, a retrospective, observational study was conducted in the 22-bed MICU at a university hospital. Data were obtained from two trained pharmacists who participated in MICU rounds three times a week. In addition to patient characteristics, data on the cause, type, related drug, and acceptance rate of interventions were collected. RESULTS: In 340 patients, a total of 1211 pharmacologic interventions were performed. The majority of pharmacologic interventions were suggested by pharmacists at multidisciplinary rounds in the MICU. The most common pharmacologic interventions were adjustment of dosage and administration (n = 328, 26.0%), followed by parenteral/enteral nutritional support (n = 228, 18.1%), the provision of drug information (n = 228, 18.1%), and advice regarding pharmacokinetics (n = 118, 9.3%). Antimicrobial agents (n = 516, 42.6%) were the most frequent type of drug associated with pharmacist interventions. The acceptance rate of interventions was 84.1% with most accepted by physicians within 24 hours (n = 602, 92.8%). CONCLUSIONS: Medication and nutritional problems are frequently encountered pharmacotherapeutic problems in the MICU. Pharmacist interventions play an important role in the management of these problems.

There are several reports to demonstrate that rifampicin, a major anti-tuberculosis agent, is associated with some adverse renal effects, with a few cases of rifampicin-induced minimal change disease (MCD). In the present case, a 68-year-old female presented with nausea, vomiting, foamy urine, general weakness and edema. She had been taking rifampicin for 4 weeks due to pleural tuberculosis. The patient had no proteinuria before the anti-tuberculosis agents were started, but urine tests upon admission showed heavy proteinuria with a 24-h urinary protein of 9.2 g/day, and serum creatinine, albumin, and total cholesterol levels were 1.36 mg/dL, 2.40 g/dL, and 283 mg/dL, respectively. MCD was diagnosed, and the patient achieved complete remission after cessation of rifampicin without undergoing steroid therapy.

BACKGROUND/AIMS: Not only scintigraphic measurement of gastric emptying(GE) is not standarized, but also several discrepancies exist in the influence of technical factors including instrument and methods of analysis on gastric emptying studies. The aim of this study was to determine whether investigating instruments, methods of analysis, affect gastric emptying rates of a radiolabeled meal in scintigraphic measurement. METHODS: Using two different scanners (single-headed gammma camera and double headed gammma camera), gastric emptying studies of radiolabeled meal (consisting of 1 g of resin) labeled with 2mCi of 99mTc-DTPA (50g of egg, 150ml of milk, 100g of rice; 611Kcal) were done in 16 healthy volunteers (16 men, age 27.5+/-3yrs). Anterior and posterior image were obtained from the supine position with two scanners at every timing interval. Anterior image only was analyzed to determine whether the differences in instruments affect gastric emptying rates. Sum of anterior and posterior counts obtained by double-headed gamma camera were compared to geometric mean. RESULTS: There were significant difference in gastric emptying rates obtained with anterior image between a single-headed scanner and a dual-headed scanner (P < 0.05, T1/2= 105.8+/-16.3 min vs 80.9+/-14.7 min). Sum of anterior and posterior counts was correlated well with geometric mean (r=0.93). Also observed difference between intraobserver and interobserver variation. CONCLUSIONS: These results indicate that instrumental variations in gastric emptying studies should be considered in interpreting individual study results. The simple sum of anterior and posterior counts could be an useful parameter in the analysis and interpretation of gastric emptying data.

Primary carcinoma of the fallopian tube is a rare malignancy of the female genital tract and infrequently diagnosed before an operation. The majority of patients have extensive disease at the time of diagnosis. We have experienced incidentally a case of a carcinoma of the fallopian tube coexisting with a benign cystic teratoma of the ovary in a 25-year-old woman. We report this case with a brief review of literatures.

Bacterial lipopolysaccharide (LPS) plays a major role in stimulating the synthesis and release of the principal osteoclast-activating cytokines, namely, interleukin 1 and tumor necrosis factor-alpha from immune cells. Although monocytes/macrophages are the main producers of these cytokines, recent evidence has indicated that polymorphonuclear leukocytes (PMN) have the ability to release IL-1 and TNF-alpha. Calcium hydroxide has been shown to be an effective medicament in root canal infections, reducing the microbial titre within the canal. It has been proposed that the therapeutic effect of Ca(OH)2 may also be the result of direct inactivation of LPS. The purpose of this study was to investigate whether treatment of Porphyromonas endodontalis LPS with calcium hydroxide alters its biological action as measured by human PMN secretion of IL-1 and TNF-alpha, and it was compared with Escherichia coli LPS. P. endodontalis ATCC 35406 was cultured in anaerobic condition, and LPS was extracted using the hot-phenol water extraction method and purified. Purchased E. coli LPS was also purified. 100 microg/ml of each LPS in pyrogen free water were incubated with 25mg/ml Ca(OH)2 at 37degrees C for 7 days. The supernatants were subjected to ultrafiltration, and the isolates were lyophilized and weighed. PMNs were obtained from peripheral blood by centrifugation layered over Lymphoprep. The cells were resuspended (4x106 cells/ml) in RPMI 1640 followed by treatment with various concentrations of LPS (0, 0.1, 1, 10microg/ml) for 24 hours at 37degrees C in 5% CO2 incubator. The supernatants of cells were collected and the levels of IL-1alpha, IL-1beta and TNF-alpha were measured by enzyme-linked immunosorbent assay. The results were as follows; 1. The levels of IL-1alpha, IL-1beta, TNF-alpha from PMN treated with each LPS were significantly higher than those released from unstimulated PMN of the control group (p<0.05). 2. The levels of all three cytokines released from PMN stimulated with each calcium hydroxide treated LPS were significantly lower than those released from PMN stimulated with each untreated LPS (p<0.05), while they were not significantly different from those released from unstimulated PMN of the control group (p>0.05). 3. The levels of secretion for all three cytokines were affected in a dose-dependent manner in PMN stimulated with each LPS (p<0.05), but not in PMN stimulated with each calcium hydroxide treated LPS (p>0.05). 4. The levels of all three cytokines released from PMN stimulated with P. endodontalis LPS were significantly lower than those released from PMN stimulated with E. coli LPS (p<0.05).
