  • Objective: Internal organs indirectly affect economic performance and well-being of animals. Study of internal organs during later layer period will allow full utilization of layer hens. Hence, we conducted a genome-wide association study (GWAS) to identify potential quantitative trait loci or genes that potentially contribute to internal organ weight. Methods: A total of 1,512 chickens originating from White Leghorn and Dongxiang Blue-Shelled chickens were genotyped using high-density Affymetrix 600 K single nucleotide polymorphism (SNP) array. We conducted a GWAS, linkage disequilibrium analysis, and heritability estimated based on SNP information by using GEMMA, Haploview and GCTA software. Results: Our results displayed that internal organ weights show moderate to high (0.283 to 0.640) heritability. Variance partitioned across chromosomes and chromosome lengths had a linear relationship for liver weight and gizzard weight ($R^2=0.493$, 0.753). A total of 23 highly significant SNPs that associated with all internal organ weights were mainly located on Gallus gallus autosome (GGA) 1 and GGA4. Six SNPs on GGA2 affected heart weight. After the final analysis, five top SNPs were in or near genes 5-Hydroxytryptamine receptor 2A, general transcription factor IIF polypeptide 2, WD repeat and FYVE domain containing 2, non-SMC condensin I complex subunit G, and sonic hedgehog, which were considered as candidate genes having a pervasive role in internal organ weights. Conclusion: Our findings provide an understanding of the underlying genetic architecture of internal organs and are beneficial in the selection of chickens.

  • 본 연구는 호흡시에 내부 장기가 움직일 때 시간에 따른 threshold 값을 주어졌을 때 선량분포에 대한 연구를 수행한 것이다. 이전 연구에서 보고 된 것처럼 일정 시간에 따라 움직이는 내부 장기의 움직임은 Rujan 등에 의해 보고된 3차원적 수학적 계산방법에 의해 장기의 위치를 나타내었다. 그 결과 처음exhale에서 1초동안 간의 움직임은 2mm이내에 위치하는 것을 알게 되었다. 그래서 이 연구에서 TGT는 간의 움직임이 가장 적은 처음 exhale에서 1초동안 움직일 때의 선량분포를 평가하였다. TGT 값을 주었을 때 선량분포를 비교하기 위해 다음 조건으로 방사선을 조사하였다. 1) threshold 범위에서 target이 움직일 때(1초, 1.5호), 2) threshold 없이 target이 움직일 때, 3) target이 움직이지 않을때. 각각 조건의 선량분포를 비교 평가하였다

  • An 11-years old spayed female Persian chinchilla cat presented with acute onset of blindness from bilateral retinal detachment and systemic hypertension. On physical examination, the cat was tachycardic (240 beats/min) with a systolic blood pressure of around 250 mmHg. Clinical findings, blood works, urinalysis, thyroid function test, radiography, echocardiogram, and ultrasonography were performed to rule out underlying diseases. Organ injury induced by systemic hypertension including bilateral retinal detachment and left ventricular hypertrophy were confirmed by ultrasound. Based on these results, it was diagnosed as feline idiopathic hypertension with target organ damage (TOD). The cat was treated with a combination therapy using high doses of amlodipine, telmisartan, and atenolol. After the treatment, its hypertension and TOD were improved. This case showed that appropriate therapeutic management can help prevent TOD associated with feline hypertension.

  • Objective: This study reports the effect of Hyungbangjihwang-tang-gami as a treatment for Soyang-in patients with chronic diarrhea. Methods: We treated three male patients with chronic diarrhea who did not improve after taking herbal medicine, as determined by zang-fu (organ) pattern diagnosis. After changing our approach to a Sasang constitution, we prescribed Hyungbangjihwang-tang-gami and assessed the effect by the frequency or form of defecation. Results: The patients' complaints worsened when they were administered a herbal medicine unsuited to their Soyang constitutions, which caused an exuberance of Yang. Changing the herbal medicine to Hyungbangjihwang-tang-gami improved their symptoms. Conclusions: This study suggested that Soyang-in patients may have side effects when administered unsuitable herbs, even if they were diagnosed using zang-fu (organ) pattern diagnosis. When we treat patients, we have to consider their Sasang constitution, as well as the zang-fu (organ) pattern diagnosis.

  • Malaria is one of the most common infectious diseases in the world. Plasmodium falciparum, accounting for nearly all malaria mortality, kills an estimated 1 to 2 million persons yearly and has several features that make it deadlist of malarias. While cerebral malaria is the most common presentation of severe disease, acute lung injury associated with malaria is uncommon but serious and fatal complication. We report two cases of severe malaria with ARDS and multi-organ failure. All two patients traveled to foreign countries, Kenya, Papua New Guinea where choroquine-resistant malaria is distributed. The first case, which developed cerebral malaria, hypoglycemia, multi-organ failure, and ARDS, treated with quinine and mechanical ventilator, but expired due to oxygenation failure. Autopsy showed acute necrotizing infiltration, diffuse eosinophilic fibrinoid deposits along the alveolar space, and alveolar macrophage with malaria pigment The second case also developed multi-organ failure, followed by ARDS, and was treated with quinine, exchange transfusion, plasmapheresis, and mechanical ventilator. He recovered with residual restrictive lung change after treatment.

  • Radiation therapy has been used for the cancer treatment and radiation synovectomy$\^$1-3)/. There are two kinds of radiation therapy; the external radiation therapy and the internal radiation therapy. Hitherto, the external radiation therapy has been widely used, but for the lack of its selectivity it requires strong radiation dose and causes the irritation and damage of the normal tissue or organ. Therefore many researchers give their interests to the internal radiation therapy in which the radioactive materials are injected directly into the target organ or tissue. Many ${\beta}$-emitting radionuclides have been studied for the application of the internal radiation theraily. Among them, Holmium-166 has the many beneficial physical characteristics for the internal radiation therapy such as appropriate half life (26.8hr), high ${\beta}$ energy (max. 1.85 MeV(51%), 1.77 MeV (48%), mean 0.67MeV), and low ${\gamma}$ energy (0.081MeV) easily detected by ${\gamma}$-camera. In the internal radiation therapy, the administered radioactive materials should be retained in the target long enough to increase the therapeutic effects and avoid the damage in the normal tissue or organ. For this purpose, radionuclides are used as complex form with carriers. Carriers should have a high affinity with radionuclides in vivo and in vitro, so the complex can be evenly distributed in the lesion but can not be leaked out from the lesion.

  • 일반적으로 현재 많이 사용하는 장기 투영 시스템은 MRI와 CT이다. MRI와 CT는 전자기장을 이용하여 인체를 절개하지 않고 내부 장기를 의사가 볼 수 있도록 한다. 하지만 문제점은 단면적으로 영상을 보여주기 때문에 의사들이 내부 장기를 입체적으로 관찰하기 어려운 문제가 있다. 이 논문에서는 증강현실의 기술을 이용하여 사람의 내부 장기를 현실에 투영 할 수 있는 시스템을 개발한다. 개발한 시스템은 홀로렌즈를 이용하여 환자의 신체위로 내부 장기를 입체 영상으로 보여주며 핸드 모션을 이용하여 내부 장기를 이동시켜 상세하게 관찰이 가능하게 한다.

  • 연구 배경 : 중환자의 예후를 예측할 수 있는 지표로 현재까지 APACHE II, III 점수체계와 SAPS 등이 임상에 응용되고 있다. 1996년 유럽에서 SOFA 점수체계가 제안되었고 1998년 다기관 전향적 연구를 통하여 장기부전을 평가하고 경과를 감시하는 간편하고 효과적인 점수체계임을 입증하였다. 이 연구는 춘천성심병원에서 내과계 중환자만을 대상으로 SOFA 점수체계의 유용성을 조사하였다. 방 법 : 2000년 5월 1일부터 6월 30일까지 춘천성심병원 내과계 중환자실에 입원한 154명을 대상으로 하였고, 이중 타과환자, 타병원으로 전원된 경우, ECG 관찰만을 위하여 입원한 경우, 처치 후 관찰을 위해 48시간 이내만 체류한 환자를 제외한 105명을 연구에 포함시켰으며, 91명에서 평가가 가능하였다. SOFA 점수와 APACHE III 점수는 입원 시부터 매일 24시간 간격으로 중환자실에서 퇴실할 때까지 하였다. 결 과 : 1) 사망률은 20%였고 중환자실 체류기간의 중앙값은 3일이었다. 2) 사망군과 생존군 간의 24시간 내 SOFA 점수는 각각 $8.17{\pm}4.05$, $3.85{\pm}3.24$로 유의한 차이가 있었다. 3) 장기부전이 없는 경우의 사망률은 6.5%, 5개의 다발성 장기부전이 있는 경우 사망률은 100%였다. 4) 48시간 이상 체류했던 74명을 분석한 결과 사망군에서는 최대 SOFA 점수가 81%에서 증가하였고 생존군에서는 21%에서 증가하여 유의한 차이를 보였다. 5) 24시간 내 SOFA 점수와 APACHE III 점수와의 관련성을 평가한 결과 r=0.85 (p<0.01)로 유의한 상관관계가 있었다. 결 론 : SOFA 점수체계는 다발성 장기부전이 있는 환자에서 장기부전을 평가하고 예후를 예측하며 임상경과를 관찰하는데 이용할 수 있는 간편하고 임상적 효용성이 있는 지표로서 임상적으로 많은 도움이 될 것으로 생각한다.

  • Objective & Method : We investigated the identity of tri-energizer, which was originally described in Huang Di Nei Jing and claimed by traditional scholars, and drew the following conclusions. Result & Conclusion : According to Huang Di Nei Jing tri-energizer is one of the six hollow-organs and is called hollow organs for digestion and elimination, water guffer organ, or solitary hollow organ. It is believed that tri-energizer is regarded as the existing entity based on following several different sources; it functions as the course of channels, regulates wind and link and physiological function-especially intrinsic function of upper, middle, lower internal organs. It also controls syndromes and dysfunction of an illness, the surface of the body, and the cracked surface of the skin. Finally, bold and timidity depend on the tri-energizer. Experts determined the true nature of tri-energizer types. Experts include: Yu Tuan from the Ming dynasty, Tang Jong Hai and Ye Lin from the Qing dynasty, and Zhang Xi Chun from the Zhunghua Minguo period. These experts' claims are based on shape and forms of tri-energizer. Our examinations of anatomical and physiological basis on tri-energizers showed that, in a narrow sense, tri-energizer indicates visceral and parietal peritoneum and omentum surrounding the internal organs, and in a broad sense, indicates the overall membrane wrapping around the whole internal organs including five visceral organs and six hollow organs.

  • Pulse diagnosis, the most popular diagnostic tool in traditional Korean medicine, had had many forms but had been fixed on using wrist pulse and placing internal organs on Cun, Guan and Chi(寸 關 尺). Wang Shuhe(王叔和) suggested placing six viscera(六腑) on Cun, Guan and Chi based on relationship between external and internal meridian vessel, and Zhang Jiebin(張介賓) criticized his suggestion and insisted that pulse diagnosis should be based on the organ system. But the origin of pulse diagnosis which can be found in "(Huangdi's) Internal Classic(黃帝內經)" is a tool mainly for diagnosis of not internal organ system but meridian system. Most of material about pulse diagnosis after Ming dynasty(明代) reinterpreted pulse diagnosis in the aspect of organ system, So there has to be additional discussion about it.
