RESUMO
Although seclusion and restraint are required for the treatment of mentally ill patients in psychiatric hospitals, these procedures involve potential violations of human rights and pose a potential risk to patients' physical condition. Nursing staffs in psychiatric hospitals often have to manage psychiatric patients who display aggressive, violent, or challenging behavior. However, the guidelines for the use of seclusion and restraint in Korea are too broad to apply in clinical situations. The guidelines in the United States, Australia, the United Kingdom, and New Zealand emphasize that patients' basic needs have to be met and stipulate that patient–staff interaction must be continued during seclusion and restraint procedures. Mental health workers in psychiatric hospitals should pay close attention to patients' verbal and non-verbal expressions while communicating with them. This study reviews the guidelines for seclusion and restraint used in foreign countries to improve current Korean guidelines and provides strategies of the nursing activities to be implemented when patients require seclusion and restraint.

Korl:ICR mice, established by the Korean National Institute of Food and Drug Safety Evaluation (NIFDS), are characterized based on their genetic variation, response to gastric injury, and response to constipation inducers. To compare the inhibitory responses of ICR stocks obtained from three different sources to the anticancer drug cisplatin (Cis), alterations in tumor volume, histopathological structure, and toxicity were examined in Sarcoma 180 tumor-bearing Korl:ICR, A:ICR (USA source), and B:ICR (Japan source) mice treated with low and high concentrations of Cis (L-Cis and H-Cis, respectively). Tumor size and volume were lower in H-Cis-treated mice than in L-Cis-treated mice in all three ICR stocks with no significant differences among stocks. There was a significant enhancement of the necrotizing areas in the histological structures in the L-Cis- and H-Cis-treated groups relative to that in the untreated group. The necrotizing area changes were similar in the Sarcoma 180 tumor-bearing Korl:ICR, A:ICR, and B:ICR mice. However, there were stock-bases differences in the serum biomarkers for liver and kidney toxic effects. In particular, the levels of AST, ALT and BUN increased differently in the three H-Cis-treated ICR stocks, whereas the levels of ALP and CRE were constant. Taken together, the results of the present study indicate that Korl:ICR, A:ICR, and B:ICR mice have similar overall inhibitory responses following Cis treatment of Sarcoma 180-derived solid tumors, although there were some differences in the magnitude of the toxic effects in the three ICR stocks.

The inhibitory effects of Asparagus cochinchinensis against inflammatory response induced by lipopolysaccharide (LPS), substance P and phthalic anhydride (PA) treatment were recently reported for some cell lines and animal models. To evaluate the hepatotoxicity and nephrotoxicity of A. cochinchinensis toward the livers and kidneys of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed in male and female ICR mice after oral administration of 150, 300 and 600 mg/kg body weight/day saponin-enriched extract of A. cochinchinensis (SEAC) for 14 days. The saponin, total flavonoid and total phenol levels were found to be 57.2, 88.5 and 102.1 mg/g in SEAC, respectively, and the scavenging activity of SEAC gradually increased in a dose-dependent manner. Moreover, body and organ weight, clinical phenotypes, urine parameters and mice mortality did not differ between the vehicle and SEAC treated group. Furthermore, no significant alterations were measured in alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and the serum creatinine (Cr) in the SEAC treated group relative to the vehicle treated group. Moreover, the specific pathological features induced by most toxic compounds were not observed upon liver and kidney histological analysis. Overall, the results of the present study suggest that SEAC does not induce any specific toxicity in the livers and kidneys of male and female ICR mice at doses of 600 mg/kg body weight/day.

A dysfunction of endoplasmic reticulum (ER) stress response can result in various diseases, including cancer, inflammation, diabetes and neurodegenerative disorders. To investigate whether ER stress response can play an essential role in the induction and treatment of chronic constipation, alterations in the key parameters for ER stress were measured in loperamide (Lop) induced constipation Sprague Dawley (SD) rats treated with aqueous extracts of Liriope platyphylla (AEtLP), which has been shown to have a laxative effect. Symptoms of chronic constipation including alteration of stool parameters and the transverse colon's structure were successfully induced by Lop treatment. Laxative effects such as enhancement of stools parameters, recovery of the mucosa thickness, increased muscle thickness and recovery of flat luminal surface were also observed in the Lop+AEtLP treated group. Furthermore, enhancement of eukaryotic initiation factor 2 alpha (eIF2α) phosphorylation and inositol-requiring enzyme 1 beta (IRE1β) expression, key indicators for ER stress, that were observed in the Lop+vehicle treated group were significantly recovered in the Lop+AEtLP treated group, although the phosphorylation level of c-Jun N-terminal protein kinase (JNK) remained constant. Moreover, alterations in the transcription level of the marker genes X-box binding protein 1 (XBP-1) and growth arrest and DNA damage-inducible protein (GADD34) were similar to those of eIF2α and IRE1β. However, their level was slightly or completely recovered after AEtLP treatment. Overall, this study provides the first evidence that ER stress response may be tightly correlated with chronic constipation induced by Lop treatment, as well as the laxative effects of AEtLP.

Alzheimer's disease (AD) is known to induce alterations of mitochondrial function such as elevation of oxidative stress and activation of apopotosis. The aim of this study was to investigate the effects of human Presenilin 2 mutant (hPS2m) overexpression on the γ-secretase complex in the mitochondrial fraction. To achieve this, alterations of γ-secretase complex expression and activity were detected in the mitochondrial fraction derived from brains of NSE/hPS2m Tg mice and Non-Tg mice. Herein, the following were observed: i) overexpression of the hPS2m gene significantly up-regulated the deposition of Aβ-42 peptides in the hippocampus and cortex of brain, ii) overexpression of hPS2m protein induced alterations of γ-secretase components such as main component protein and activator protein but not stabilization-related proteins, iii) changes in γ-secretase components induced by overexpression of hPS2m protein up-regulated γ-secretase activity in the mitochondrial fraction, and iv) elevation of γ-secretase activity induced production of Aβ-42 peptides in the mitochondrial fraction. Based on these observations, these results indicate that alteration of γ-secretase activity in cells upon overexpression of hPS2m is tightly linked to mitochondrial dysfunction under the specific physiological and pathological conditions of AD.

Animal models of constipation induced with drugs and diet have been widely employed to investigate therapeutic effects and the action mechanism of drugs against this disease. ICR mice were selected to produce this disease model through oral administration of loperamide (Lop), even though SD rats are commonly utilized in studies of constipation. To compare the responses of ICR mice obtained from three different sources to constipation inducers, alterations in stool number, histopathological structure, mucin secretion and opioid-receptor downstream signaling pathway were measured in Korl:ICR (Korea FDA source), A:ICR (USA source) and B:ICR (Japan source) injected with low and high concentrations of Lop (LoLop and HiLop). The number, weight and moisture content of stools decreased significantly in the Lop treated group of all ICR relative to the Vehicle treated group. Additionally, decreased mucosa layer thickness, muscle thickness, and mucin secretion were observed in the transverse colon of Lop treated ICR mice, while a similar number of goblet cells and crypt of lieberkuhn were detected in the same group. Furthermore, a similar change in the level of Gα expression and PKC phosphorylation was detected in the Lop treated group relative to the vehicle treated group, while some differences in the change pattern were observed in the B:ICR group. Therefore, these results of the present study provide strong additional evidence that Korl:ICR, A:ICR and B:ICR derived from different sources have a similar overall response to constipation induced by Lop injection, although there were a few differences in the magnitude of their responses.

Animal models for gastric ulcers produced by physical, pharmacological and surgical methods have been widely employed to evaluate therapeutic drugs and investigate the mechanism of action of this disease. ICR mice were selected to produce this model, even though several mice and rats have been widely used in studies of gastric ulcers. To compare the responses of ICR mice obtained from three different sources to gastric ulcer inducers, alterations in gastric injury, histopathological structure, and inflammation were measured in Korl:ICR (Korea NIFDS source), A:ICR (USA source) and B:ICR (Japan source) treated with three concentrations of ethanol (EtOH) (50, 70, and 90%) in 150 mM hydrochloric acid (HCl) solution. Firstly, the stomach lesion index gradually increased as the EtOH concentration increased in three ICR groups. Moreover, a significant increase in the level of mucosal injury, edema and the number of inflammatory cells was similarly detected in the EtOH/HCl treated group compared with the vehicle treated group in three ICR groups. Furthermore, the number of infiltrated mast cells and IL-1β expression were very similar in the ICR group derived from three different sources, although some differences in IL-1β expression were detected. Especially, the level of IL-1β mRNA in 50 and 90EtOH/HCl treated group was higher in Korl:ICR and A:ICR than B:ICR. Overall, the results of this study suggest that Korl:ICR, A:ICR and B:ICR derived from different sources have an overall similar response to gastric ulcer induced by EtOH/HCl administration, although there were some differences in the magnitude of their responses.

Asparagus cochinchinensis has been used to treat various diseases including fever, cough, kidney disease, breast cancer, inflammatory disease and brain disease, while IL-4 cytokine has been considered as key regulator on the skin homeostasis and the predisposition toward allergic skin inflammation. However, few studies have investigated its effects and IL-4 correlation on skin inflammation to date. To quantitatively evaluate the suppressive effects of ethyl acetate extracts of A. cochinchinensis (EaEAC) on phthalic anhydride (PA)-induced skin inflammation and investigate the role of IL-4 during their action mechanism, alterations in general phenotype biomarkers and luciferase-derived signals were measured in IL-4/Luc/CNS-1 transgenic (Tg) mice with PA-induced skin inflammation after treatment with EaEAC for 2 weeks. Key phenotype markers including lymph node weight, immunoglobulin E (IgE) concentration, epidermis thickness and number of infiltrated mast cells were significantly decreased in the PA+EaEAC treated group compared with the PA+Vehicle treated group. In addition, expression of IL-1β and TNF-α was also decreased in the PA+EaEAC cotreated group, compared to PA+Vehicle treated group. Furthermore, a significant decrease in the luciferase signal derived from IL-4 promoter was detected in the abdominal region, submandibular lymph node and mesenteric lymph node of the PA+EaEAC treated group, compared to PA+Vehicle treated group. Taken together, these results suggest that EaEAC treatment could successfully improve PA-induced skin inflammation of IL-4/Luc/CNS-1 Tg mice, and that IL-4 cytokine plays a key role in the therapeutic process of EaEAC.

To investigate the beneficial effects of diosgenin (DG) on the multiple types of brain damage induced by Aβ-42 peptides and neurotoxicants, alterations in the specific aspects of brain functions were measured in trimethyltin (TMT)-injected transgenic 2576 (TG) mice that had been pretreated with DG for 21 days. Multiple types of damage were successfully induced by Aβ-42 accumulation and TMT injection into the brains of TG mice. However, DG treatment significantly reduced the number of Aβ-stained plaques and dead cells in the granule cells layer of the dentate gyrus. Significant suppression of acetylcholinesterase (AChE) activity and Bax/Bcl-2 expression was also observed in the DG treated TG mice (TG+DG group) when compared with those of the vehicle (VC) treated TG mice (TG+VC group). Additionally, the concentration of nerve growth factor (NGF) was dramatically enhanced in TG+DG group, although it was lower in the TG+VC group than the non-transgenic (nTG) group. Furthermore, the decreased phosphorylation of downstream members in the TrkA high affinity receptor signaling pathway in the TG+VC group was significantly recovered in the TG+DG group. A similar pattern was observed in p75NTR expression and JNK phosphorylation in the NGF low affinity receptor signaling pathway. Moreover, superoxide dismutase (SOD) activity was enhanced in the TG+DG group, while the level of malondialdehyde (MDA), a marker of lipid peroxidation, was lower in the TG+DG group than the TG+VC group. These results suggest that DG could exert a wide range of beneficial activities for multiple types of brain damage through stimulation of NGF biosynthesis.

Some polymers and bioactive compounds derived from Styela clava tunic (SCT) have been reported as traditional medicine for the treatment of inflammation, oxidative stress and surgical wounds although there is little scientific evidence of their liver and kidney toxicity. To investigate the toxicity of ethanol extracts of SCT (EtSCT) in the liver and kidney of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed following oral administration of 50 and 100 mg/kg body weight/day of EtSCT for 14 days. EtSCT showed a high level of free radical scavenging activity for DPPH (93.1%) and NO (16.2%) as well as the presence of 14.8 mg/mL of flavonoids and 36.2 mg/mL of phenolics, while EtSCT treated groups did not show any significant alterations in the body and organ weight, clinical phenotypes, urine parameters or mice mortality when compared with the vehicle treated group. In addition, constant levels of serum biochemical markers including alanine phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN) and serum creatinine (CRE) were maintained. Moreover, no specific histopathological features induced by most toxic compounds were observed in liver and kidney sections stained with hematoxilin and eosin. Therefore, the present results indicate that EtSCT with strong antioxidant activity cannot induce any specific toxicity in liver and kidney organs of ICR at doses of 100 mg/kg body weight/day.

BACKGROUNDS/AIMS: Recent advances in ultrasonography have contributed to the early detection of gallbladder cancer. We attempted to predict the progression of the disease by comparing the sizes of polypoid lesions, and we suggest that the size of the lesion would be a useful guideline to determine an appropriate primary surgical approach for polypoid lesions of the gallbladder. METHODS: We have retrospectively analyzed 253 patients that, during the operation period from January 2009 to December 2011, had had ultrasonographically detected gallbladder polypoid lesions, and who underwent cholecystectomy at Ulsan university hospital. We have analyzed the demographic data of the patients, the preoperative size of polypoid lesions, and pathologic findings. RESULTS: Of a total of 253 patients, 235 patients had benign lesions, and 18 patients had malignant lesions. Among the malignant polyp patients, 11 had pT1 cancer, 6 had pT2 cancer, and 1 had pT3 cancer. The average size of polypoid lesions was 9.1+/-3.1 mm and that of malignant lesions was 28.2+/-16.4 mm. The receiver operating characteristic (ROC) curve of the benign and malignant groups shows that 14.5 mm is the optimal point of prediction of the malignancy. Of a total of 18 patients of GB cancer, 11 had pT1 and the average size of their polypoid lesions was 20.5+/-5.8 mm 7 had pT2 with a size of 39.1+/-20.7 mm. ROC curve analysis of the pT1 and pT2 groups shows that 27 mm would be the optimal point to predict T2 and above cancer. CONCLUSIONS: In the case of an early cancer, curative treatment can be achieved through a simple and minimally invasive laparoscopic cholecystectomy. We attempted to predict early cancer occurrence among polypoid lesions of the gallbladder using the simplest standard, size. Although there are some limitations, size can be a simple and easy way to evaluate polypoid lesions of the gallbladder.

Although formaldehyde (FA) is known to be a major allergen responsible for allergic contact dermatitis, there are conflicting reports regarding correlation between FA exposure and interleukin (IL-4) expression. To investigate whether allergic responses including IL-4 expression were induced by repeated dermal exposure to low dose FA, alterations in the luciferase signal and allergic phenotypes were measured in IL-4/Luc/CNS-1 transgenic (Tg) mice containing luciferase cDNA under control of the IL-4 promoter after exposure to 4% FA for 2 weeks. High levels of luciferase were detected in the abdominal region of the whole body and submandibular lymph node (SLN) of FA treated mice. Additionally, the ear thickness and IgE concentration were significantly upregulated in the FA treated group when compared with the acetone olive oil (AOO) treated group. FA treated mice showed enhanced auricular lymph node (ALN) weight, epidermis and dermis thickness, and infiltration of inflammatory cells. Furthermore, the expression of IL-6 among T helper 2 cytokines was higher in the FA treated group than the AOO treated group, while vascular endothelial growth factor (VEGF) levels remained constant. Overall, the results presented herein provide additional evidence that various allergic responses may be successfully induced in IL-4/Luc/CNS-1 Tg mice after exposure to low dose FA for 2 weeks. The luciferase signal under the IL-4 promoter may reflect general indicators of the allergic response induced by exposure to low dose FA.

Atopic dermatitis (AD), which is known as the most common pruritic skin disease, is caused by epidermal barrier dysfunction, allergies, microwave radiation, histamine intolerance, and genetic defects. To investigate the therapeutic effects of fermented soycrud (FSC) on AD pathology, alteration of AD phenotypes induced by phthalic anhydride (PA) treatment was assessed by ear thickness analysis, measurement of immune-related organ weights, ELISA, and histological and pathological analyses of ICR mice after FSC treatment for 2 weeks. Except for water content, the concentrations of most major components were lower in FSC compared to common tofu (CMT). Thymus and lymph node weights were significantly reduced in ICR mice treated with PA+CMT or PA+FSC, whereas spleen and body weights were maintained. Elevation of ear thickness induced by PA treatment was rapidly diminished in the CMT- and FSC-treated groups, although there was no significant difference between the two groups. Furthermore, significant reduction of epidermal thickness was detected in both the PA+CMT- and PA+FSC-treated groups. However, IgE concentration and dermal thickness were reduced only by PA+FSC treatment, whereas PA+CMT treatment maintained levels comparable to PA+vehicle treatment. The number of infiltrated mast cells was higher in the PA+vehicle-treated group compared to the untreated control. Following CMT or FSC treatment, mast cell infiltration was slightly reduced, although the CMT-treated group showed greater cell numbers. These results indicate that FSC may significantly relieve the phenotypes of AD induced by PA treatment and should be considered as a potential candidate for AD therapy.

OBJECTIVE: To analysis the 10 cases of relaparotomy for intractable hemorrhage after emergency postpartum hysterectomy with massive transfusion. METHODS: Between January 1995 and December 2008, relaparotomies for intractable hemorrhage and unstable vital sign after emergency postpartum hysterectomy with massive transfusion were performed on 10 patients. Medical records were reviewed and detailed to collect clinical data including patients' clinical status, causes of bleeding, duration from hysterectomy to relaparotomy, bleeding sites, procedures for bleeding control, amount of transfusions, complications and prognosis. RESULTS: In relaparotomies, the points of bleeding were identified in all cases and multiple bleeding foci than one bleeding focus were found, and procedures for bleeding control were performed. In 8 cases, the bleeding were controlled successfully and these patients recovered without long term sequales. But in the other 2 cases, although the bleeding controls were successful during relaparotomy and bleeding amount decreased after relaparotomy, but bleeding amount increased the next day and angiographic embolizations were performed. These patients died due to multi-organ failure and continued bleeding. In one of these cases, the endotracheal intubation had been done on arrival at our hospital with postpartum hemorrhage after vaginal delivery at private clinic. In another case, the cardiopulmonary resuscitation was performed on arriving at our hospital with intractable bleeding after postpartum subtotal hysterectomy in other hospital. CONCLUSION: In most cases, bleeding controls for intractable bleeding after postpartum hysterectomy were successful during and after relaparotomy in spite of development of dilutional coagulopthy due to massive transfusion, and resulted in rapid recovery and good prognosis. Even though dilutional coagulopthy was developed because of massive transfusion, relaparotomy was safe and effective procedure for management of intractable hemorrhage after emergency postpartum hysterectomy with clotting factor replacement. If personnel and adequate clotting factor replacement are available, relaparotomy should not be delayed for management of intractable hemorrhage and unstable vital sign after emergency postpartum hysterectomy.
