Abdominal compartment syndrome (ACS) is a life-threatening disorder caused by rapidly increasing intra-abdominal pressure. ACS can result in multiorgan failure and carries a mortality of 60~70%. The treatment of choice in ACS is surgical decompression. There are very few reports of ACS and experience in Korea. We report 12-year-old male patient who developed an abdominal compartment syndrome due to traffic-accident-induced retroperitoneal hematomas, Which was successfully treated by performing a bedside emergency surgical decompression with open linea alba fasciotomy with intact peritoneum. When patients do not respond to medical therapy, a decompressive laparotomy is the last surgical resort. In patients with severe abdominal compartment syndrome, the use of a linea alba fasciotomy is an effective intervention to lower intra-abdominal hypertension (IAH) without the morbidity of a laparotomy. Use of a linea alba fasciotomy as a first-line intervention before committing to full abdominal decompression in patients with abdominal compartment syndrome improves physiological variables without mortality. Consideration for a linea alba fasciotomy as a bridge before full abdominal decompression needs further evaluation in patients with polytrauma abdominal compartment syndrome.

조생종 '쓰가루' 사과의 단기저장 중 품질유지를 위한 몇 가지 수확후 처리 효과를 살펴 출하시기조절을 위한 방안을 마련하고자 하였다. 저장한 과실의 품질은 수확후 처리보다는 숙기에 많은 영향을 받았다. 경도 및 내적 품질을 고려하였을 때 착색정도가 중간 단계인 과실이 저장에 유리하였다. 수확후 처리 중 단순 PE포장은 증산억제에 따른 무게감량 방지에 효과적이었으나 기타의 품질에 대한 효과는 뚜렷하지 않았다. 그러나 에틸렌제거제 포장처리는 과실품질 유지에 긍정적인 효과를 보여주었다. 특히 산 함량이 높게 유지되어 과실은 더욱 신선하였다. 본 연구 수행 중 $0-1^{\circ}C$ 저장온도에서 생리적 장해가 주로 악편부위에 발생하였으며 미숙한 상태의 과실일수록 그 정도가 심하였다. 증상은 부정형의 작은 반점이 형성되었으며 반점부위의 표피조직은 함몰되었는데 일부 과실은 수침증상의 반점이 비교적 크게 형성되기도 하였다. 따라서 앞으로의 연구에서는 '쓰가루' 사과의 적정 저장온도에 대한 보다 세밀한 검토가 필요하였다.

Chronic exposure to high levels of manganese leads a pronounce and debilitating disorder known as manganism. Research on the toxic manifestation of manganese have focused primarily on its neurological effects because exposure to high levels of the metal produces a distinct and irreversible extrapyramidal dysfunction resembling the dystonic movements associated with Parkinson's physiological and biochemical systems in the body. The purpose of this study was to evaluate the effect of manganeses on primary rat calvarial cell growth and toxicity. The experimental groups were in concentration of 0, 10, 30, 60, 100, 300 ${\mu}M$. Cell activity was assessed at day 1 and day 3 using a fluorescent molecular probe. Cell proliferation was evaluated at day 1 and day 3 by MTT assay. The amount of total protein synthesis was measured at day 3 and day 7. The results were as follows: The proliferation of primary rat calvarial cells were inhibited by $MnCl_2$ in the concentration exceeding $100{\mu}M$. The primary rat calvarial cells treated with $MnCl_2$ showed similar protein synthesis to the control group except in 100 ${\mu}M$. These result suggest that manganese suppress the viability and protein synthesis of primary rat calvarial cells in concentration exceeding $100{\mu}M$.

Chronic exposure to high levels of manganese (Mn) leads a pronounced and debilitating disorder known as manganism. Research on the toxic manifestation of manganese have focused primarily on its neurological effects because exposure to high levels of the metal produces a distinct and irreversible extrapyramidal dysfunction resembling the dystonic movements associated with Parkinson's physiological and biochemical systems in the body. The purpose of this study is to determine the effects of Mn on mineralization in primary rat calvarial cells. The experimental groups were in concentration of 0, 10, 30 and 60 ${\mu}M$. The results were as follows: 1. ALP activity was decreased in concentration of 30 and 60 ${\mu}M$ (p<0.01). 2. Bone nodule formation was depressed in concentration of 30 and 60 ${\mu}M$ at day 14 and 21 (p<0.01). 3. RT-PCR results showed an altered expression of bone matrix proteins. These result suggested that manganese might decrease or alter the expression of the osteoblast phenotype.

Byobusan area of Aomori prefecture in Japan was a marshy sand dune and had developed for agricultural land use with a large-scale sprinkler system. Recently, it becomes an agricultural problem at this area that distinctive damage with browning maculation and fissures frequently occurs in Chinese yam tubers. Acetaldehyde is one of the factor candidates of underground part damage in plants. In this study, incidence rate of the tuber damage, and the morphological character and elemental composition of the damage parts in tubers were investigated with applications of excessive irrigation water or acetaldehyde water solution into the yam field. The incidence rate of the distinctive tuber damage increased as the input amount of irrigation water was increased. At the browning maculation parts of the tubers, many fissures and damages of cork layer were observed under scanning electron microscopy. In addition, the periderm of tubers was significantly thicker in damaged parts than in non-damaged parts. Funguses, bacterium and nematodes were not observed in the damaged part under scanning electron microscopy. The weight ratio of each constituent element in an analyzed area relative to the total weight of major essential elements was measured with energy dispersive X-ray spectrometry. The results showed that the weight ratios of boron, carbon, phosphorus, sulfur and calcium were higher in damaged parts than in non-damaged parts whereas the weight ratios of oxygen and chlorine were lower in damaged parts than in non-damaged parts. It was also shown by this spectrometry that iron, cadmium, lead and zinc were not directly involved in occurrence of the tuber damage. In this study, there was no remarkable difference of tuber appearance between non-acetaldehyde and acetaldehyde application treatments. From the above results, it is shown that the damage would be a physiological disorder induced by the input of a large quantity of water in the sandy field.

Rheumatoid arthritis is a chronic, systemic, and inflammatory autoimmune disorder that affects 1% of the adult population worldwide. Osteoarthritis is a multifactorial disease with high morbidity that is characterized by degradation of the matrix and destruction of articular cartilage. In this study, we examined the inhibition effect of Trachelospermi Caulis on the inflammation($TNF-{\alpha}$, $IL-1{\beta}$, NO), cartilage protection(MMP-13), and cell death in arthritis. RAW 264.7 and SW 1353 cells were cultivated in DMAE(GibcoBRL, USA) with 5% FBS and Fungizone in $37^{\circ}C$, 5% CO2. THP-1 cells were cultivated in RPMI(GibcoBRL, USA) with 5% FBS and Fungizone in $37^{\circ}C$, 5% CO2. Activity of caspase-3, XIAP, Cytochrome C in the cell was examined by using western blot. The results obtained were as Follows; Concentration of nitric oxide in Trachelospermi Caulis treatment group significantly decreased compared with that of non-treatment group (P<0.05). In treated group, Concentration of Trachelospermi Caulis was not significantly associated with cell death. Concentration of $TNF-{\alpha}$ and $IL-1{\beta}$ in Trachelospermi Caulis treatment group decreased significantly compared with that of none treatment group (P<0.05). Relative density of MMP-13 in Trachelospermi Caulis treatment group decreased significantly compared with that of none treatment group and dose-response relationship was observed. After treatment of staurosporin in SW1353 which increases cell death, in Trachelospermi Caulis treated group, the cell death was effectively decreased. In conclusion, these results suggest that Trachelospermi Caulis inhibit inflammation and cell death in arthritis. More researches about effect of Trachelospermi Caulis are considered to need.

Benign prostatic hyperplasia(BPH) is a common disease among male. However, its cause and treatment are not known and it is easy to relapse to the patients again after some treatment. Chinese has got an active research on BPH of traditional Chinese medicine. We researched the Chinese clinical papers from 2000 to 2014. After translating those papers, we analyzed total 45 papers by classifying those according to frequently used prescriptions, differentiation of symptoms, signs, addition and subtraction of each medicine and the quantity of frequently used medicines. Through this study it was to provide evidence in the diagnosis and treatment of BPH. The prescription of BPH was classified according to its stage. Mainly damp heat patterns(濕熱型) induce dysuria, Qi-stagnation and blood stasis patterns(氣滯血瘀型) induce pain, While Kidney deficiency patterns(腎虛型) induce sexual function disorder. This analysis report would be able to provide the basis of taking a research on BPH. In addition, it could be applied on a stereotype of BPH as well as a variety of symptoms with frequently used prescription and addition and subtraction of each medicine.

Warm disease: Any of various heat disease characterizer by rapid onset and shifts, pronounced heat signs, and a tendency to form dryness and damage yin. Exterior heat sign: exterior heat patterns are characterizer by pronounced heat signs, such as a red sore pharynx and a relatively red tongue with dry fur, the pulse is floating and rapid, cough and the production of thick white or yellow phlegm. If wind-heat evil exist in weifen, it becomes exterior syndrome, and a remedy about that is dispelling wind-heat but when wind-heat evil invades in nasal and throat part so the disease occurs, you need to add relieving sore throat worsens invades in lung it makes disharmony of diffuse in lungs. So a remedy about it is diffuse the lung. disharmony of diffuse in lungs makes metabolic disorder of qi and liquid and humor malfunction therefore it occurs cough and heat-phlegm syndrome. heat from weifen invades the whole of lungs and form lung heat. So a remedy about lung heat is clearing away lung heat, this lung heat makes inevitably bleed in lungs, therefore a remedy in this case is clearing the lung to stop bleeding, or moistening the lung. Exterior heat sign means that exterior syndrome coexists with heat syndrome and it means that a remedy of this syndrome need to mix prescriptions for relieving exterior syndrome and heat-clearing prescriptions to treat this syndrome.
