The neuroleptic malignant syndrome (NMS) is an uncommon but dangerous complication of treatment with neuroleptic drugs. This syndrome is characterized by autonomic dysfunction, extrapyramidal dysfunction, and hyperthermia. NMS seems more frequent with parenteral neuroleptic use. We report a patient in whom suspicious NMS was developed in the ward after epidural administration of 2.5mg of droperidol with morphine for postoperative pain control. Extrapyramidal symptoms and autonomic dysfunction were treated with diazepam, but temperature was spontaneously decreased after 16 hours and 40 minute after receiving epidural droperidol.

To demonstrate the effect of formulation conditions on the controlled release of protein from poly(lactide-co-glycolide) (PLGA) microspheres for use as a parenteral drug carrier, ovalbumin (OVA) microspheres were prepared using the W/O/W multiple emulsion solvent evaporation and extraction method. Methylene chloride or ethyl acetate was applied as an organic phase and poly(vinyl alcohol) as a secondary emulsion stabilizer. Low loading efficiencies of less than 20％ were observed and the in vitro release of OVA showed a burst effect in all batches of different microspheres, followed by a gradual release over the next 6 weeks. Formulation processes affected the size and morphology, drug content, and the controlled release of OVA from PLGA microspheres.

To estimate the effect of some injectable antibiotics (ampicillin sodium, cefazolin sodium, cephaloridine, cefuroxime sodium and chloramphenicol sodium succinate) on pyrogen tests, the Limulus amebocyte lysate (LAL) test and an ultrafiltration technique were used. The rabbit pyrogen test was also used in the case of cafazolin sodium. At high antibiotic concentrations, these samples which were artificially contaminated with endotoxin inhibited the gelation reaction of LAL. But the gelation reaction occurred when most of the antibiotic was removed by ultrafiltration. Likewise, cefazolin sodium interfered not only with the LAL test but also with the rabbit pyrogen test. From these results it can be said that special modification to eliminate interference should be taken into consideration for valid method of pyrogen tests in the parenteral products containing these antibiotics.

Purpose. Paclitaxel has demonstrated significant activity in clinical trials against a wide variety of tumors. The clinical application of Taxol$\^$\ulcorner/, a commercial product of solubilized paclitaxel with co solvents of ethanol and Cremophor, however, has been limited largely by hypersensitivity of the excipient. The aim of this study was to formulate paclitaxel-loaded lipid nanodispersions (Px-LN) for i.v. administration without toxic excipients, and to evaluate in vitro characteristics and in vivo pharmacokinetic behaviors.

There have been many changes in hospital pharmacy after division of medical practice and dispensing. Many pharmacist leave hospital pharmacy to drugstore. Because reduced number of pharmacist, many of hospital pharmacies are placed in difficulty. Restructuring of hospital pharmacy made us consider substitution hospital admixtured TPN(total parenteral nutrition) with industrial manufactured TPN. But we have no data established to support that, so we have sarried out the comparison of two kinds of TPn formulary. We have divided into groups receiving hospital admixtured TPN and industrial manufactured TPN patients in august. 2002. We have compared with each groups in nutritional related dose, parameters and complication before and after TPN administration and also invertigated the reason of formulary change in each groups. We expect that this study will be good data for selection TPN formulary and substitution hospital admixtured TPN with industrial manufactured TPN.

Lung-resident memory T cells (T_RM) play an essential role in protecting against pulmonary virus infection. Parenteral administration of DNA vaccine is generally not sufficient to induce lung CD8 T_RM cells. This study investigates whether intramuscularly administered DNA vaccine expressing the nucleoprotein (NP) induces lung T_RM cells and protects against the influenza B virus. The results show that DNA vaccination poorly generates lung T_RM cells and massive secondary effector CD8 T cells entering the lungs after challenge infection do not offer sufficient protection. Nonetheless, intranasal administration of non-replicating adenovirus vector expressing no Ag following priming DNA vaccination deploys NP-specific CD8 T_RM cells in the lungs, which subsequently offers complete protection. This novel 'prime and deploy' strategy could be a promising regimen for a universal influenza vaccine targeting the conserved NP Ag.

Purpose: Preterm infants are very susceptible to malnutrition because of a lack of storage of nutrients, immature digestion and metabolism, and accompanying diseases associated with prematurity. The purpose of this study was to evaluate the effects of nutritional support by the pediatric nutritional support team (pNST) on the clinical course of preterm infants in the neonatal intensive care unit (NICU). Methods: Between July 2003 and July 2006, 48 preterm infants who were admitted to the NICU at Seoul National University Bundang Hospital were included. The subjects were divided into the following two subgroups according to the presence of NST activity; pre-NST group (n=23) and NST group (n=25). Hospital records were reviewed retrospectively. Results: Forty-eight preterm babies were included (M：F=27：21; gestational age, 25~33 weeks). A dietician, pharmacists, or the pNST participated in the prescription of total parenteral nutrition (TPN) more rapidly in the NST group (p=0.000). The fasting periods and TPN administration periods were significantly decreased in the NST group compared to the pre-NST group (p=0.017 & p=0.001, respectively). The doses of calories, protein, and lipids administered via TPN were significantly increased in the NST group compared to the pre-NST group (p=0.016, p=0.000, and p=0.000, respectively). The total period on antibiotic therapy was significantly decreased in the NST group compared to the pre-NST group (p=0.007). Conclusion: Because nutritional support by the pNST is of benefit to the clinical course of preterm infants in the NICU, the pNST should recommend to improve the nutritional status and clinical outcome of preterm infants.

Purpose : Cholestasis is a major complication in prolonged use of TPN, especially in the neonatal period, but there are few long-term reviews examining the clinical course in premature infants. Thus, in this study, we reviewed premature infants with TPN-associated cholestasis(TPNAC) to determine the incidence, clinical courses and possible risk factors. Methods : Retrospective review of 66 premature infants less than 2,000 gm of birth weight and on TPN for more than two weeks was performed. Cholestasis was defined as a serum direct bilirubin level greater than 2.0 mg/dL. The clinical course of cholestasis was described, and perinatal risk factors were evaluated. Results : TPNAC developed in 21 out of 66 infants(31.8%). The onset was $41.7{\pm}17.4days$ after receiving TPN, and the mean duration was $33.6{\pm}23.4days$. The incidence of TPNAC was significantly correlated with birth weight, and gestational age, and duration of TPN. But, possible etiologic factors, such as incidence of perinatal asphyxia or infection, showed no remarkable differences between infants with TPNAC and those without TPNAC(control). The enteral intake in the third postnatal week was significantly smaller in infants with TPNAC than in the control infants(P=0.033). Conclusion : The enteral intake in the third postnatal week was smaller in the infants with TPNAC than in the control infants. Thus, the incidence of TPNAC may be reduced by increasing the amount of oral intake during TPN in high risk infants.

Purpose: Ursodeoxycholic acid (UDCA) is known to decrease hepatic injury by promoting the biliary secretion of retained toxic endogenous bile acids in hepatobiliary diseases complicated by total parenteral nutrition (TPN). However, most studies have focused on treatment for complications after TPN. We investigated the preventive role of early administration of UDCA in TPN-induced hepatobiliary complications by a randomized, double-blind, placebo-controlled trial. Methods: Between May 2000 and May 2002, thirteen patients, who were given TPN more than 10 days in the hospital, were assigned randomly to two groups. One was the case group (7 patients) who were given UDCA simultaneously with TPN regimen, and the other, the control group (6 patients) who were given placebo. Their age ranged from 1 day to 13 years. They were affected with diseases impossible for enteral nutrition, such as prematurity, cerebral palsy, chronic diarrhea, anorexia nervosa, pancreatitis, and cyclic vomiting. The duration of TPN ranged from 10 to 70 days. Hematologic parameters including liver function test were measured at regular intervals, and the duration, composition, administration rate, total calorie of TPN were recorded. The serum levels of total bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase were compared between groups after cessation of the study. Results: The autoregressive coefficient of the control group was 0.4419 (p=0.0651) in bilirubin, -0.0431 (p=0.7923) in AST, 0.2398 (p=0.2416) in ALT, and 0.2459 (p=0.1922) in alkaline phosphatase by mixed procedure model when the parameters were referred to the case group. Conclusion: The serum level of total bilirubin did not increase in comparison with that of the control group, but statistically insignificant, when both TPN and UDCA were administered simultaneously from the beginning.

This study evaluated the nutrition intake and changes in laboratory data of surgery patients with hypermetabolic severity on nutrition support. From January 2002 to September 2002, 66 hospitalized surgery patients who had received enteral nutrition (EN, n=19) and total parenteral nutrition (TPN, n=47) for more than 7 days were prospectively and retrospectively recruited. The laboratory data was examined pre-operatively, and on the post-operative 1, 3, 7 day and at the time of discharge. The characteristics of the patients were examined for the hypermetabolic severity, The hypermetabolic scores were determined by high fever ($>38^{\circ}C$), rapid breathing (>30 breaths/min), rapid pulse rate (>100 beats/min) , leukocytosis ($WBC>12,000/{\mu}l$), leukocytopenia ($WBC>3,000/{\mu}l$), status of infection, inflammatory bowel disease, surgery and trauma. The scores for the hypermetabolic status were divided into three groups (mild 0-10, moderate 11-40, severe>41). According to the results of the study, 38.3% (n=23), 45.4% (n=30) and 19.6% (n=13) were in the mild, moderate, and severe groups, respectively. There was a decrease in the serum albumin level and weight loss according to the hypermetabolic severity. However, the white blood cells (WBC), fasting blood sugar (FBS), c-reactive protein (CRP), total bilirubin, GOT, and GPT increased. The nutritional intake was TPN (32.5 kcal/kg, protein 1.2 g/kg, fat 0.25 g/kg), EN (28.1 kcal/kg, protein 1.0 g/kg, fat 1.01 g/kg). The serum albumin, hemoglobin and cholesterol were higher in the EN group than in the TPN group. But the FBS, total bilirubin, GOT and GPT were higher in the TPN group than the EN group. In conclusion, there was a negative correlation between the changes in the laboratory data and the hypermetabolic severity. There was an increase in the number of metabolic complications in the TPN group.
