For the effective administration of narcotic antagonist, the application of sustained release implantable systems with biodegradable polyphosphazene was examined. Using poly[(diethyl glutamate)-co-(ethyl glycinate) phosphazene]. the implantable devices containing naloxone hydrochloride were prepared and in vivo implantation studies were carried out subcutaneously in rat and rabbit with this preparation for the biocompatibility and pharmacokinetics. The histological finding in rats at initial time period was the inflammation that occurred focally around the implants, but they were showed subsequent mild and limited chronic inflammations and the irreversible changes such as necrosis and degeneration of the muscle or connective tissues were not observed. Therefore the placebo and naloxone implants are considered to be biocompatible formulations histologically. In pharmacokinetic studies, the release of naloxone from the naloxone implants into blood plasma was maintained in 192 hours, but the initial burst effect was observed. If this problem was solved, the application for the narcotic antagonist sustained release systems can be expected.

A recombinant human erythropoietin (rHuEPO) was administered intravenously at dosage levels of 0, 100, 500, and 2500 IU/㎏/day for a period of 13 weeks. There were no observed clinical signs and deaths related to treatment in all groups tested. Decreases in body weight gain and food consumption were observed only in males of 2,500 IU/㎏ group after 2 weeks. In hematological parameters, erythrocyte content, hematocrit values and hemoglobin concentration were dose-dependently increased in rHuEPO treated groups. The ratio between kidney weight and whole body weight was significantly increased in females of 500 and 2,500 IU/㎏ groups. The spleen weight was also increased in both sexes of 500 and 2,500 IU/㎏ groups. However, the absolute weight change of other organs was not observed. In histopathological examinations, the renal tubular basophilia was observed only in males and females of 2,500 IU/㎏ groups. From these results, it is concluded that the no-observed adverse effect level(NOAEL) of rHuEPO is 100 IU/㎏ in rats in the present study.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

Objective Early detection and proper management of mental illness can help to prevent severe deterioration. However, with limited financial and human resources of community mental health services, it is not practical to carry out all conventional screening tools simultaneously. In this study, we aimed to develop and validate a brief but comprehensive screening questionnaire for four common mental illnesses of the elderly. Methods The brief screening for four mental illnesses of elderly (BS4MI-elderly) is a 14-item binary response questionnaire that covers dementia, depressive disorder, sleep disorder, and hwa-byung. To test validity, we compared conventional scale scores for three groups of participants classified using the BS4MI-elderly. The sensitivity, specificity, predictive value of positive test, likelihood ratio of positive test and internal consistency of the BS4MI-elderly were assessed. Finally, a correlation analysis between the BS4MI-elderly and general mental health scales was conducted. Results A total of 254 participants aged over 65 years were recruited. The BS4MI-elderly showed moderate to high sensitivity for the test that distinguishes the normal group from the risk and disorder groups (dementia: 0.61, depressive disorder: 0.88, sleep disorder: 0.85, hwa-byung: 0.94) and high specificity for the test that distinguishes the disorder group from the normal and risk groups (dementia: 0.91, depressive disorder: 0.93, hwa-byung: 0.84, sleep disorder: 0.84). The BS4MI-elderly also exhibited good internal consistency and significant correlations with general mental health scales. Conclusion The BS4MI-elderly, a brief but comprehensive screening tool, could be a useful instrument for screening the elderly in community mental health services.

During the process of melanogenesis, oxidative stress which is one of the main causes of melanocyte damage, is generated from various sources including reactive intermediates, such as NO, and melanin intermediates with oxidant properties. It has been found that NO and NO-induced cyclic guanosine monophosphate (cGMP) pathway plays an important role in Ultraviolet B (UVB)-induced melanogenesis via induction of tyrosinase expression. In an attempt to find a novel compound reducing oxidative stress and melanogenesis, we evaluated anti-inflammatory and NO scavenging effects of (2RS,4R)-2-(2,3- dihydroxyphenyl)thiazolidine-4-carboxylic acid (MHY384) in vitro and in vivo. The purpose of this study is to investigate the effect of MHY384 on NO mediated melanogenesis in vitro and in vivo, using B16F10 melanoma cell and melanin-possessing hairless mice, HRM2 models, respectively. The NO scavenging activity of MHY384 was evaluated in cell-free system. Our in vitro study determined that MHY384 inhibited melanogenesis via regulating tyrosinase activity by NO-induced cGMP signaling pathway in B16F10 melanoma cells. In vivo experiment was conducted in HRM2 hairless mouse mice which are pre-treated with MHY384 and then irradiated with UVB repeatedly. Expressions of phosphorylated cAMP response element-binding protein (pCREB), tyrosinase, and nuclear Microphthalmia-associated transcription factor (MITF), and NO, peroxynitrite and reactive oxygen species (ROS) were measured by morphological, histological or biochemical analyses.MHY-384 was proved to be effective at scavenging nitric oxide (NO), which serves as an important modulator in the melanogenesis signaling pathway. MHY-384 significantly inhibited 200 μM sodium nitroprusside (SNP, a NO donor)-induced NO generation in dose dependent manner. In addition, MHY-384 suppressed tyrosinase activity and melanin synthesis induced by SNP in B16F10 melanoma cells. The effect of MHY-384 on NO-mediated pathway was also investigated. The gene expressions of tyrosinase and MITF and the protein level of pCREB, which are normally increased by UVB and oxidative stress, were down-regulated by MHY-384. HRM2 hairless mice were used to evaluate anti-melanogenic effects of MHY384 in vivo. It was found that MHY-384 modulated UVB-induced morphological, histological and biochemical changes, such as expression of tyrosinase and nuclear MITF and production of NO, ONOO? and ROS. In conclusion, MHY-384 inhibited NO-mediated melanogenesis by direct NO scavenging as well as reducing the expression of tyrosinase via NO/cGMP signaling pathway. It might be utilized for the development of a new candidate for treatment of the hyper-pigmentation disorders.
