  • Purpose: In this study, we attempted to ascertain the proton magnetic resonance spectroscopy (${1}^H$ MRS) peak characteristics of human gastric tissue layers and finally to use the metabolic peaks of MRS to distinguish between normal and abnormal gastric specimens. Materials and Methods: Ex-vivo ${1}^H$ MRS examinations of thirty-five gastric specimens were performed to distinguish abnormal gastric tissues invaded by carcinoma cells from normal stomach-wall tissues. High-resolution 400-MHz (9.4-T) ${1}^H$ nuclear magnetic resonance (NMR) spectra of two gastric layers, a proper muscle layer, and a composite mucosasubmucosa layer were compared with those of clinical 64- MHz (1.5-T) MR spectra. Three-dimensional spoiled gradient recalled (SPGR) images were used to determine the size and the position of a voxel for MRS data collection. Results: For normal gastric tissue layers, the metabolite peaks of 400-MHz ${1}^H$ MRS were primarily found to be as follows: lipids at 0.9 ppm and 1.3 ppm; alanine at 1.58 ppm; N-acetyl neuraminic acid (sialic acid) at 2.03 ppm; and glutathione at 2.25 ppm in common. The broad and featureless featureless spectral peaks of the 64-MHz MRS were bunched near 0.9, 1.3, and 2.0, and 2.2 ppm in human specimens without respect to layers. In a specimen (Borrmmann type III) with a tubular adenocarcinoma, the resonance peaks were measured at 1.26, 1.36 and 3.22 ppm. All the peak intensities of the spectrum of the normal gastric tissue were reduced, but for gastric tumor tissue layers, the lactate peak split into 1.26 and 1.39 ppm, and the peak intensity of choline at 3.21 ppm was increased. Conclusion: We found that decreasing lipids, an increasing lactate peak that split into two peaks, 1.26 ppm and 1.36 ppm, and an increasing choline peak at 3.22 ppm were markers of tumor invasion into the gastric tissue layers. This study implies that MR spectroscopy can be a useful diagnostic tool for gastric cancer.

  • According to the result about 'San Jiao(三焦)'recorded on "Yellow Empero's Canon Internal Medicine Ling Shu(黃帝內經 靈樞)", we achieved following results. 1. As we consider the concept of 'San Jiao' recorded on "Ling Shu", in early time, it was related to bladder(膀胱) and there was no divided concept into 'Shang Jiao(上焦)', 'Zhong Jiao(中焦)' and 'Xia Jiao(下焦)'. Later, there was appearance of body metabolism concept in anatomic way and started to emphasize that stomach(胃) is the very beginning of digestion. This point then adjusted into the concept which the core theory of digestion and water metabolism begins with 'Zhong Jiao' and processes to 'Shang Jiao' and 'Xia Jiao' then it established the 'San Jiao' theory adjusted to the functional change than property change. Later as there is set theoretical structure of 'three Yin and three Yang(三陰三陽)', it included the concept of 'San Jiao' onto meridian system theory to complete as a theory. Finally, it completed the theoretical structure that 'San Jiao' runs water metabolism of circulation, body fluid and urine for body to produce blood and Qi to protect and provide nutrition to the human body. 2. From the point of each part, 'San Jiao' means all body composition factor related to the relation to the digestion and water metabolism to produce Qi and blood. Also, the details of entire function of 'San Jiao' tells that 'Zhong Jiao' intakes food and divides the clarity and turbidity of digested substances. The origin of this digestion and water metabolism lies at Xia Jiao. The clean substance including the mood and taste climbs via Shang Jiao. The vapor like substance climbed to Shang Jiao becomes 'defensive Qi(衛氣)' and controls body temperature and sweat by supporting and spreading the Qi by Shang Jiao. The liquid substance climbed to Shang Jiao becomes blood. The blood has stronger character as substance than defensive Qi so Zhong Jiao becomes the base and the way for the blood. The turbid Qi separated at Zhong Jiao passes large intestine and the solid substance is excreted and the liquid is absorbed into bladder. The Xia Jiao that controls this process controls the liquid state of water matabolism so control the urine with bladder. Therefore, 'San Jiao' can be understood as a general concept that controls entire water metabolism as a way of food, Qi and blood.

  • The retinoids (vitamin A and its derivatives) play a critical role in vision, growth, reproduction, cell differentiation and embryonic development. Using the IMpRH panel, porcine cellular retinol binding protein genes 5 and 7 (RBP5 and RBP7) were assigned to porcine chromosomes 5 and 6, respectively. The complete coding sequences (CDS) of the RBP5 and RBP7 genes were amplified using the reverse transcriptase polymerase chain reaction (RT-PCR) method, and the deduced amino acid sequences of both genes were compared to human corresponding proteins. The mRNA distributions of the two genes in adult Wuzhishan pig tissues (lung, skeletal muscle, spleen, heart, stomach, large intestine, lymph node, small intestine, liver, brain, kidney and fat) were examined. A total of nine single nucleotide polymorphisms (SNPs) were identified in two genes. Three of these SNPs were analyzed using the polymerase chain reaction-restriction-fragment length polymorphism (PCR-RFLP) method in Laiwu, Wuzhishan, Guizhou, Bama, Tongcheng, Yorkshire and Landrace pig breeds. Association analysis of genotypes of these SNP loci with economic traits was done in our experimental populations. Significant associations of different genotypes of $RBP5-A/G^{63}$, $RBP5-A/G^{517}$ and $RPB5-T/C^{intron1-90}$ loci with traits including maximum carcass length (LM), minimum carcass length (LN), marbling score (MS), back fat thickness at shoulder (SBF), meat color score (MCS) and hematocrit (HCT) were detected. These SNPs may be useful as genetic markers in genetic improvement for porcine production.

  • 'On the Morbid Pulse of Abdominal Fullness, Cold Mounting, and Abiding Food' in the Chapter 10 of Synopsis of Golden Chamber that enunciates Abdominal Fullness, Cold Mounting, and Abiding Food is related to the stomach and intestines respectively, and is similar to the region and symptom of disease in the light of both abdominal fullness and symptoms of pain. This chapter was united into one because the formula mentioned in this chapter can be applied to three disease patterns. Abdominal fullness shows the symptoms of distention and unease, but judging from the text as well as a specific formula and symptoms, it follows pain. Accordingly Abdominal fullness dealt with in this chapter is the first consideration and it is a kind of a disease pattern attendant on abdominal pain. Cold Mounting does not mean mounting gi disease but means the abdominal pain. The cause of cold mounting is mainly due to insufficiency of yang gi and oversufficiency of cold evil. And the main symptoms of cold mounting follow the severe pain around the naval and sweating, cold of the extremities, pulse deep and tight. Abiding food is of the same meaning such as damage of food today. Abiding food is now referred to as damage of food. Principles which have set forth in this chapter are put to use of the method of ejection in case that abiding food places in the upper part, precipitation in the lower part. The symptoms of abiding food show that the pulse is slight and slippery and the wrist pulse is both superficial and large and rough in applying the pressure, and the cubit pulse is also slight and superficial as well, and that have diarrhea and have little appetite.

  • Purpose: In East Asian countries, there are only a few epidemiologic studies of eosinophilic esophagitis (EoE) and no studies in children. We investigated the incidence and compared the clinical characteristics of EoE and eosinophilic gastroenteritis involving the esophagus (EGEIE) in Korean children. Methods: A total of 910 children, who had symptoms of esophageal dysfunction, from 10 hospitals in Korea were included. EoE was diagnosed according to diagnostic guidelines and EGEIE was diagnosed when there were >15 eosinophils in the esophagus per high power field (HPF) and >20 eosinophils per HPF deposited in the stomach and duodenum with abnormal endoscopic findings. Results: Of the 910 subjects, 14 (1.5%) were diagnosed with EoE and 12 (1.3%) were diagnosed with EGEIE. Vomiting was the most common symptom in 57.1% and 66.7% of patients with EoE and EGEIE, respectively. Only diarrhea was significantly different between EoE and EGEIE (p=0.033). In total, 61.5% of patients had allergic diseases. Exudates were the most common endoscopic findings in EoE and there were no esophageal strictures in both groups. The median age of patients with normal endoscopic findings was significantly younger at 3.2 years, compared to the median age of 11.1 years in those with abnormal endoscopic findings (p=0.004). Conclusion: The incidence of EoE in Korean children was lower than that of Western countries, while the incidence of EGEIE was similar to EoE. There were no clinical differences except for diarrhea and no differences in endoscopic findings between EoE and EGEIE.

  • 본 연구는 전해환원수 음용에 대한 안전성을 조사하기 위하여 실험동물을 이용하여 사망률 확인, 체중 비교, 혈액의 생화학적 변화, 염증, 면역세포의 비교, 내부 장기의 형태적 변화, 장기의 무게 변화 및 조직학적 검사를 통하여 전해환원수가 생체에 미치는 영향을 확인한 결과 다음과 같은 결론을 얻었다. 전해환원수를 급이한 실험군에서 사망, 행동 및 외형 이상 유무 관찰 결과 아무런 증상이 나타나지 않았으며, 체중은 감소하는 경향을 보였다. 실험군에서 혈액의 생화학적요소인 $K^+$, $Cl^-$, $Ca^{2+}$, GPT, GOT, CRE 및 ALP에서는 유의한 수준의 변화가 관찰되지 않았으나 $Na^+$와 BUN에서는 실험군이 대조군에 비해 더 감소되었다. 혈액 내 면역세포를 비교한 결과 호염기구, 호산성구 및 단핵구 등은 큰 차이가 없으며, 실험군에서 호중구는 감소하였고, 림프구는 증가하는 경향을 보였다. 또한 위, 소장, 심장 및 간을 조직학적으로 관찰한 결과 모든 장기에서 병리적 이상 소견은 관찰되지 않았다. 따라서 본 연구를 통하여 전해환원수는 생체에서 큰 문제를 유발시키지 않는 안전한 물임을 알 수 있었고 국내에서 전해환원수에 대한 연구가 거의 없는 실정이기 때문에 전해환원수의 안전성을 입증하기 위한 기초자료 마련 및 제공에 의의가 있다고 할 수 있다.
