Purpose: Many studies have examined the mechanisms of impaired glucose homeostasis after organophosphate (OP) exposure, however no study has evaluated the clinical utility of blood glucose measurements in patients with OP poisoning. The current study was conducted to evaluate the initial glucose level at presentation and the glycemic variables during the first 3 days after admission as a predictor of mortality. Methods: This retrospective observational case series included 228 patients with a history of OP poisoning. Among other clinical data, information on the initial glucose level at presentation and mean glucose level, delta glucose level, and the presence of a hypoglycemic event during the first 3 days of admission, was collected. Results: Survivors had lower initial glucose levels at presentation and glucose variability during the first 3 days of admission compared to non-survivors. The frequency of hypoglycemic events was higher in non-survivors. In multivariate analysis, the initial glucose level (> 233 mg/dl) was an independent predictor of mortality, along with age. Conclusion: The initial glucose level at presentation can be helpful in prediction of mortality in cases of OP intoxication at bedside. The physician should pay attention to patients with a glucose level>233 mg/dl at presentation after ingestion of OP.

면역에 대한 관심은 점차 증가하는 추세이며, 식물유래 천연물을 이용한 면역기능 증강에 관련된 연구 역시 활발히 진행되고 있다. 왕느릅나무 껍질은 줄기 혹은 뿌리의 껍질을 뜻하며 전통적으로 동·서양 할 것 없이 항염, 진통, 항암, 상처치료에 사용되어 왔다. 본 연구는 왕느릅나무 열수 추출물(Ulmus macrocarpa water extract, UMWE)이 면역기능에 끼치는 영향을 조사하기 위해 실시되었다. 실험은 UMWE를 농도 100 mg/kg 또는 200 mgkg로 식이한 군, UMW를 농도 100 mg/kg 또는 200 mg/kg으로 식이하면서 면역억제물질인 cyclophosphamide (CY, 120 mg/kg)를 투여한 군, CY만을 투여한 군, 아무 것도 처리하지 않은 비처리군, 총 6개 군으로 나누어 2주간 매일 식이하면서 진행하였다. 각 군에서 획득한 비장지수와 비장세포 지수를 비교하였을 때 UMWE 식이가 CY에 의한 비장세포의 감소를 완화시키는 것으로 나타났으며, in vitro 실험에서 MTT방법과 7-amino-actinomycin D 방법을 통해 비장세포의 생존을 유지하며 사멸을 지연하는 것이 확인되었다. 또한, UMWE는 YAC-1에 대한 비장 NK 세포 활성을 면역억제제 CY가 존재하는 조건에서도 정상적으로 유지시켜 면역기능 유지에 영향을 주는 것으로 나타났다. Ulmi cortex is the elm bark or root bark of Ulmus macrocarpa Hance and has been used as an ingredient of traditional medicine for anti-inflammatory, analgesic, anti-cancer and wound healing on both the East and the West. This study investigated whether the Ulmus macrocarpa Hance Water extract (UMWE) has the in vivo and in vitro immune activating effect. Animals were orally administrated for 14 days as follows: no treat group with distilled water, cyclophosphamide (CY) group with 120 mg/kg of CY, UMWE 100+CY group with 100 ㎎/㎏ of UMWE and 120 mg/kg of CY, UMWE 200+CY group with 200 ㎎/㎏ of UMWE and 120 mg/kg of CY, UMWE 100 group with 100 ㎎/㎏ of UMWE and UMWE 200 group with 200 ㎎/㎏ of UMWE. The immunosuppressive drug CY was intraperitoneally injected to induce immune suppression. Spleen indices showed small changes in CY injected groups but splenocyte indices showed greater decrease in the same groups. However, UMWE appeared to relieve CY"s immunosuppression. UMWE also delayed in vitro splenocyte death increasing its longevity. These data obtained by MTT assay and 7-amino-actinomycin D which stains preferentially dead than live cells. UMWE alone did not show cytotoxicity based on its apoptototic effect on splenocytes in vitro and in vivo. Splenic NK cell activity was maintained by UMWE under the presence of CY in vitro. The data indicated that UMWE protects splenocytes from the immunosuppressive drug CY under in vitro and in vivo conditions.

약용식물은 염증, 감염증, 암과 같은 질병에 광범위하게 사용되고 있으며, 전통적으로 오래 동안 사용되어 왔다. 왕느릅나무(Ulmus macrocarpa Hance)는 느릅나무의 한 종으로서 중국, 일본을 비롯해 한국 전역에 분포하고 있으며, 줄기와 뿌리의 껍질을 유백피라 하여 한의학에서 피부염, 유방염, 부종 등에 사용하여 왔다. 이 연구의 목적은 유백피의 열수 추출물(Ulmus cortex water extract, UCWE)이 면역조절 기능을 가지고 있는지를 조사하는 것이다. UCWE 식이농도 30 mg/kg, 100 mg/kg, 300 mg/kg의 3개 군으로 나누어 14일 동안 식이한 후 면역반응을 측정하였다. IL-2, IL-12, IFN-γ 의 혈중 농도가 UCWE를 식이한 군에서 유의적으로 증가하였으며, lymphokine activated killer cells (LAK)을 이용한 세포매개 세포독성 시험에서도 정상군에 비해 UCWE를 식이한 군에서 유의적으로 증가하였다. 그러나, 간, 신장, 비장, 흉선의 무게변화는 UCWE를 식이한 군과 정상군과의 차이가 없었다. 이는 300 ㎎/㎏ 고농도의 2주간 식이가 장기에 영향을 거의 미치지 않는다는 것을 암시한다고 생각된다. 따라서, UCWE는 내부 장기에는 영향을 주지 않으며 면역기능을 향상시키는 효과를 가진다고 여겨진다. Traditional medicinal plants are widely used to treat many diseases, such as inflammation, infections, and even cancer. Ulmus macrocarpa Hance, a Chinese elm species, is distributed in Korea, China, and Japan. The stem bark is widely employed in Korean traditional medicine to treat dermatitis, mastitis, and edema. The aim of this study was to investigate whether water extract of U. macrocarpa Hance bark (Ulmus cortex) has a immune-modulating function in a mouse model. Three different concentrations (30 ㎎/㎏, 100 mg/kg, and 300 ㎎/㎏) of Ulmus cortex water extract (UCWE) were orally administered to mice for 14 days, and their immune responses were analyzed. Cytokines, such as interleukin (IL)-2, IL-12, and IFN-γ, increased in the blood of UCWE-fed groups when compared with a control group. In contrast, the IL-4 level did not change in any of the UCWE-fed groups Cell-mediated cytotoxicity was also assayed using lymphokine-activated killer cells (LAK). LAK showed greater cytotoxicity in the UCWE-fed groups than LAK in the control group. Internal organ indices, such as liver, kidney, spleen, and thymus, were similar in all the groups, including the control group, indicating that UCWE may have been nontoxic in the experimental animals. These data suggest that UCWE has an immune-modulating function in a mouse model.

The improved properties of corrosion for 90Cu10NiFe alloy in natural seawater were explained by sodium diethyl dithio carbamate(NaDDC), namely organic compound, which is reagent for heavy metal extractions of waste water. The efficiency of NaDDC as corrosion inhibitor for 90Cu10NiFe alloy has been investigated in seawater after immersion in various concentrations of NaDDC solutions for 12~36hrs at pH 8.2 by weight loss test and electrochemical techniques including potentiodynamic polarization and SEM-EDS measurements. The results showed that the corrosion resistance of 90Cu10NiFe alloy improves with the increasing concentration of NaDDC but it did not improves with increasing time any more, so the highest inhibition efficiency was 93% at 100mg/L, 36hrs. The results obtained from weight losses and corrosion rates in polarization curve measurements were in good agreement. Therefore, it showed that NaDDC is a good inhibitor for copper corrosion of 90Cu10NiFe alloy.

Objective : The purpose of this study is to investigate clinical characteristics with 25 patients who have suffered from headache and were treated. Methods : We classified 25 patients into several groups by IHS classification and evaluated the effects of oriental medical therapy on headache. Results : 1. According to the statistics, instances of migraine were more prevalent than tension headache, especially among women. 2. 28% of patient had entered for treatment within one month of onset. 3. Common associated symptoms included dizziness, nausea, dyspepsia, palpitation and insomnia. 4. In classification by the oriental medical differentiation of symptoms and signs, the rate of stagnation of the humid dam and deficiency of qi, these two types were highest. 5. 56% of patients said they were satisfied with the treatment, reporting half the frequency of headache or better from before treatment. Conclusions : The present results suggest that oriental medical therapy has effects on headache. Further clinical comparative studies on herb-medication versus acupuncture therapy for headache are urged.
