During the use of API X70 steel as a pipeline structural material for the transportation of natural gas,hydrogen embrittlement can occur due to the hydrogen contained in natural gas. The aim of this study is toinvestigate the effects of the hydrogen content under high-pressure hydrogen gas conditions on the hydrogenembrittlement of air-cooled API X70 steel. The air-cooled API X70 steel was manufactured by hot rollingand was then air-cooled to room temperature. Tensile test specimens were held for 0 h, 1000 h, and 2000 hwithin a pressure vessel filled with 100% hydrogen gas at a gas pressure of 10 MPa, with the tensile teststhen performed at room temperature. The microstructure of the API X70 steel consists of coarse polygonalferrite, coarse pearlite, and fine acicular ferrite. The yield and tensile strength increased and elongationdecreased considerably after a holding time of 2000 h compared to those of 0 h and 1000 h within the pressurevessel. The morphology of the fracture surface changed from ductile to brittle upon hydrogen gas charging. Secondary cracks were observed in both of the hydrogen-gas-charged specimens. No external cracks wereformed on the surface of the tensile-tested specimen with a 0 h holding time; however, many external crackswere observed on the specimen surface subjected to hydrogen gas charging.

Objectives : The purpose of this study is to report a 67-year-old male patient with Herpes zoster(caseⅠ) and a 38-year-old female patient with Herpes zoster(caseⅡ), whose symptoms were relieved after Korean medicine treatment alone. Methods : Both patients took Yeonryeonggobondan and Pyungwee-san daily. Everytime they came to the hospital, they received acupuncture treatment, Hwidam's Su-Gi therapy and External Gigong Therapy. Acupuncture was applied by gall bladder seunggyeok(膽勝格, GB-), spleen jeonggyeok(脾正格, SP+), large intestine seunggyeok(大腸勝格, LI-) of Saam's Acupuncture Method. Hwidam's Su-Gi therapy was applied on neck. External Gigong Therapy was applied on skin lesion area. the patients' symptoms were evaluated with photographs and VAS. Results : The results were as follows: 1. In the case of a 67-year-old male patient, it took 14 days to recover the skin lesions and to reduce the pain after treatment started. And he visited 13 times during that period. 2. In the case of a 38-year-old female patient, it took 23 days to recover the skin lesions to reduce and the pain after treatment started. And she visited 10 times during that period. 3. Intensive treatment early in treating herpes zoster helped to shorten the treatment period. 4. Taking Yeonryeonggobondan and Pyungwee-san and receiving acupuncture treatment(SP+) can help to improve immunity and recover skin lesions in herpes zoster diagnosed with spleen deficiency with dampness encumbrance(脾虛濕困) and blood stasis due to qi stagnation(氣滯血瘀). 5. The combination of acupuncture treatment(GB-) and External Gigong Therapy was effective in controlling pain. 6. External Gigong Therapy is considered to be effective for the recovery of the skin as well as the pain of the herpes zoster. Conclusions : Korean medicine treatment alone has a great effect on the above two patients with herpes zoster. I hope the active research about Korean medicine treatment will be done not only for herpes zoster but also for various intractable pain diseases.

Purpose: Photodynamic therapy (PDT) is a novel treatment modality, which produces local tissue necrosis with laser light following the prior administration of a photosensitizing agent. Radachlorin has recently been shown to be a promising PDT sensitizer. In order to elucidate the antitumor effects of PDT using Radachlorin on cervical cancer, growth inhibition studies on a HPV-associated tumor cell line, TC-1 cells in vitro and animals with an established TC-1 tumor in vivo were determined. Materials and methods: TC-1 tumor cells were exposed to various concentrations of Radachlorin and PDT, with irradiation of 12.5 or 25 J/cm2 at an irradiance of 20 mW/cm2 using a Won-PDT D662 laser at 662 nm in vitro. C57BL/6 mice with TC-1 tumor were injected with Radachlorin via different routes and treated with PDT in vivo. A growth suppression study was then used to evaluate the effects at various time points after PDT. Results: The results showed that irradiation of TC-1 tumor cells in the presence of Radachlorin induced significant cell growth inhibition. Animals with established TC-1 tumors exhibited significantly smaller tumor sizes over time when treated with Radachlorin and irradiation. Conclusion: PDT after the application of Radachlorin appears to be effective against TC-1 tumors both in vitro and in vivo.(Cancer Res Treat. 2004;36:389-394)

It is known that the poor soil fertility of newly reclaimed saline soils is due to the lack of organic matter and available mineral nutrients for crop production. The effect of green manuring with Sesbania aculeata in combination with five rates of urea-N treatments (N0. N25, N50, N75, N100) on the productivity of a subsequent whole-crop barley and the fertility of the reclaimed saline soil in Saemangeum was evaluated in the field during 2013-2014 growing season. Sesbania was grown during summer season (June to October). The amount of Sesbania incorporated was 16.2 Mg ha<SUP>-1</SUP>. Sesbania contributed to 393 kg N ha<SUP>-1</SUP> to the soils when ploughed down and incorporated before whole-crop barley cultivated. The performances of whole-crop barley following sesbania incorporation were significantly affected by a combination of Sesbania manuring and different N rates. The N fertilizer equivalence without N fertilizer following Sesbania was 42.6% (63.9 kgN ha<SUP>-1</SUP>), compared with N100(150 kg N ha<SUP>-1</SUP>) in fallow soils. The whole-crop barley yield responded to N fertilizer rates in both sesbaniaamended and fallow soil. The yield response to nitrogen rates in fallow soil was linear (Y=0.0586X+3.3011, R<SUP>2</SUP> =0.9534), whereas that in sesbania-amended soils was quadratic (Y= -0.001X<SUP>2</SUP>+0.1322X+5.7143, R<SUP>2</SUP>=0.9576). The yield of whole-crop barley in sesbania-amended with increasing N rates was increased up to SN75 (115 kgN) 10.3 Mg ha<SUP>-1</SUP>. Apparent N recovery (ANR) of whole-crop barely showed decreased with sesbania plus increasing rates of N fertilizer. Despite higher yield with sesbania manuring plus increasing N rates, the contributions of N from Sesbania with increasing N rates to whole-crop barley were decreased, whereas those from fertilizer increment due to excessively mineralized Nitrogen. Considering yield, ANR, N contribution from Sesbania and nitrogen fertilizer, the optimum N rate was N50 rate following sesbania incorporation.

Hemolytic Uremic Syndrome Occurred after Esophagectomy: A Case Report

Su Hyeon Park,Sung Tae Jeong,Seok Jai Kim,Hong Beom Bae,Sung Su Chung,Sang Hyun Kwak Korean Society of Critical Care Medicine 2007 Acute and Critical Care Vol.22 No.1

Hemolytic uremic syndrome is an unusual and uncommon disease in adults but more common in children, which is defined by the triad of acute renal failure, thrombocytopenia, and microangiopathic hemolytic anemia. We report a 64-year-old man who developed hemolytic uremic syndrome after esophagectomy and esophagogastrostomy due to esophageal cancer. We treated him using continuous renal replacement therapy and plasmapheresis with large volume fresh frozen plasma transfusion for 9 days. We could not find the cause of hemolytic uremic syndrome, and so finally concluded that it is idiopathic. Bleeding continuously without a particular reason after an operation, it needs an early diagnosis and treatment with considering a possibility of the hemolytic uremic syndrome.

Su Mi Bae,Seung Won Huh,Eun Kyung Park,Keun Ho Lee,Joon Mo Lee,Sung Eun Namkoong,Sei-Jun Han,Chong Kook Kim,Jong-Ki Kim,Yong-Wan Kim,Woong Shick Ahn 대한암학회 2003 Cancer Research and Treatment Vol.35 No.6

Purpose: In order to elucidate the antitumor effect ofphotodynamic therapy (PDT), using a derivative of thephotosensitizing agent hematoporphyrin (Photogem) anda diode laser, the cell death of uterine cancer cell lines(CaSki, HT3, HeLa, and SKOV-3), and mice transplantedwith TC-1 lung cancer cells, were evaluated.Materials and Methods: The morphological changes,MTT assay, flow cytometry, cytotoxicity and tumorgrowth inhibition study were evaluated at various timeintervals after the PDT.Results: The results showed that the survival rates ofeach cell line decreased with time and dose responseafter performing the PDT. Also, the PDT-induced damageof cancer cells was almost entirely confined to necrosisof the tumor cells in the early time courses. The irradiationof CaSki cells in the presence of Photogem inducedplasma membrane disruption and cell shrinkage, indicatingthe plasma membrane as the main target forPhotogem. In the in vivo experiment, significantly longersurvival and a significantly smaller tumor size were seenover the time courses of the Photogem with irradiationcompared to the untreated control groups; resorption ofthe tumor was also observed after the PDT treatment.Conclusion: Collectively, our results indicated that Photogempossesses anti-tumor effects, and necrosis- likedeath, with plasma membrane damage, was postulated tobe the principal mechanism of the antitumor effect of thePDT using Photogem.
