4,4'-diaminodiphenyl sulfone (dapsone) is a sulfone drug that has antibacterial effects on a variety of bacteria, especially Mycobacterium leprae; thus, it has been used to treat leprosy. Previous studies demonstrated that dapsone inhibits integrin-mediated adherence of neutrophils and production of prostaglandin $E_2$ by polymorphonuclear leukocytes. Hence, dapsone may act in immune cells and regulate cell-mediated inflammation processes. However, its anti-inflammatory effects remain unclear. The present study demonstrated that dapsone modulates the production of inflammation-related cytokines in immune cells. We employed the spleen cells of mice, which are major immune cells, and lipopolysaccharide (LPS) as a causative agent of inflammation for experiments. Dapsone induced a proportional change in splenocyte subsets and the apoptosis of spleen cells. Interestingly, dapsone decreased the production of tumor necrosis factor-alpha and interleukin (IL)-10, but not IL-6, in LPS-treated spleen cells. In other assays, we measured the dapsone-induced production of nitric oxide (NO) and the expression of activation markers of spleen cells. Dapsone decreased NO production in LPS-treated spleen cells. Taken together, our results demonstrate that dapsone has anti-inflammatory effects in immune cells and provide new insight into the potential uses of this agent.

Seopcheonsa(葉天士) regarded the cause of Stomach-Eum[胃陰] deficiency as the lack of fluid and humor induced the heat by Eum(陰, yin) deficiency constitution, external pathogen, overexertion and fatigue, misused medication etc. He said that the symptoms of Stomach-Eum deficiency was related to indigestion of food and that it induced the short supply of nutrition for the whole body and the symptoms by disabled Earth[土]-engenders-Metal[金]. He presented the treatment of clearing Stomach-Fire[胃熱] and nourishing Stomach-Eum[胃陰], and used Geumgwemaekmundongtang(金匱麥門冬湯). And he emphasized Stomach-Eum to supplement existing Spleen-Yang[脾陽] centered treatment. Dangjonghae(唐宗海) regarded Spleen-Eum[脾陰] as these, first, it was fluid and humor such as digestive enzyme. Secondly, it was nutritive substance itself. Finally, it contained plaster-oil and blood-agglutination which formed flesh with nutritive substance. Seopcheonsa and Dangjonghae both thought that fluid and humor was necessary to digest food. However, Dangjonghae's Spleen-Eum[脾陰] included nutritive substance as the result of digestion. So we can say that Dangjonghae integrated Spleen-Eum with Stomach-Eum and Spleen-nutrient.

Ginsan is an acidic polysaccharide purified from Panax ginseng, a famous oriental herb. Although a variety of biological activities of ginsan have been studied, the effects of ginsan on spleen cells are not fully elucidated. We investigated the effect of ginsan on the viability and proliferation of spleen cells. Using Cell Counting $Kit-8^{(R)}$ solution and trypan blue solution, we found that ginsan significantly enhanced viability and proliferation. Multiple clusters, indicating proliferation, were observed in ginsan-treated spleen cells and, carboxyfluorescein succinimidyl ester and surface marker staining assay revealed that ginsan promoted proliferation from $CD19^+$ B cells rather than $CD4^+$ or $CD8^+$ T cells. In addition, ginsan decreased the percentage of late apoptotic cells. Ginsan increased the surface expression of CD25 and CD69 as well as production of interleukin-2 from spleen cells, suggesting increased activation. Taken together, these results demonstrate that ginsan increases the viability and proliferation of spleen cells via multiple mechanisms, valuable information for broadening the use of ginsan in clinical and research settings.

Objectives : The purpose of this study was to investigate the anti-oxidative effect of Suhwagije-decoction (SGT) pharmacopuncture solution on the liver and spleen cells of aged rats. Methods : The liver and spleen cells of 10, 52, and 72 week old Sprague Dawley (SD) rats were divided into three groups: distilled water (DW), Vit.C, and SGT groups, which were treated with DW, Vit.C and SGT pharmacopuncture solution respectively. The levels of superoxide dismutase (SOD), glutathione (GSH) and nitric oxide (NO) were then measured. Results : 1. Treatment of SGT pharmacopuncture solution significantly decreased NO concentration in spleen cells of 52 week old rats as compared with that of other groups. 2. Treatment of SGT pharmacopuncture solution significantly increased SOD activity in spleen cells of 72 week old rats as compared with that of other groups. Conclusions : Suhwagije-decoction (SGT) pharmacopuncture solution may have an anti-oxidative effect in the spleen cells of aged rats.

Collagen is a family of proteins which consists of several genetically distinct molecular species and is intimately involved in tissue organization, function, differentiation and development. The purpose of this study was to investigate the concentration of different hydroxyproline (Hyp) fractions viz., total, free, peptide-bound, protein-bound, soluble- and insoluble-collagen hydroxyproline (Hyp) in various bovine tissues. Results showed that liver had the highest concentration of free Hyp followed by kidney, brain, spleen, lungs, muscle and heart. Liver also had the highest concentration of peptide-bound collagen Hyp followed by kidney, heart, spleen, lungs, brain and muscle. The concentration of protein-bound collagen Hyp was highest in the liver, followed by kidney, spleen, lungs, muscle, brain and heart. Total Hyp was highest in the liver, followed by kidney, spleen, brain, heart, muscle and lungs. Liver also had significantly high concentration of collagen as compared to other tissues examined (P<0.001). Spleen had the significantly higher concentration of soluble-collagen Hyp when compared to other tissues (P<0.001). This was followed by heart, muscle, lungs, brain, kidney and liver. Heart had the highest concentration of insoluble-collagen Hyp followed by lungs, kidney, liver, muscle, spleen and brain. The variation among the insoluble-collagen Hyp concentration of heart and muscle, spleen and brain was significant (P<0.001). We speculate that these differences could be due to the variation in turn over of rate of collagen metabolism in this species.

Toxoplasma gondii infection induces parasite infiltration and apoptosis in the spleen. However, dose-dependent parasite infiltration, apoptosis, body weight alternations and survival in mice remain largely unknown. In this study, mice were intraperitoneally infected with 10, 30 or 100 tachyzoites of T. gondii, respectively. Parasite infiltration and apoptosis in the spleen were analyzed on days 3, 7, and 9 post-infection by immunohistochemistry and flow cytometry. Significantly higher levels of T. gondii infiltration and apoptosis in the spleen were found in 30 and 100 tachyzoites infected mice compared to 10 tachyzoites infected mice on days 7 and 9 post-infection. Although 30 and 100 tachyzoites infected mice showed significant body weight loss compared to 10 tachyzoites infected mice, all of the 100, 30, and 10 tachyzoites infected mice died by days 12, 15, and 17, each respectively. Interestingly, T. gondii infiltration in 10 tachyzoites infected mice were limited to capsule area of the spleen on day 9 post-infection. Several areas of parasite infiltrations were found in the 30 tachyzoites infected mice, where noticeable levels of splenic capsule de-adhesion occurred. These results indicated that parasite infiltration and apoptosis in the spleen, as well as body weight loss (survival) are closely correlated with infection dosage. The level of T. gondii infiltration and apoptosis in the spleen and splenic de-adhesion were dependent on the parasite dose.

비장종대를 일으킬 수 있는 질환에는 감염성질환, 간경화, 기타 간질환, 비정상혈구에 의한 혈류질환, 림프계질환, 면역성질환 등이 있다. 따라서, 정상적인 비장의 크기를 아는 것은 비장의 정상 여부와 비장종대의 진단에 도움을 주며, 추적검사에도 유용하게 이용될 수 있다. 초음파검사에서 최대길이 12cm 미만, 두께 5cm 미만이면 정상적인 크기라고 여겨지나 성별, 인종에 따라 다를 수 있다. 저자들은 우리나라 20대 학생들을 대상으로, 초음파 검사로 비장크기를 측정하여, 비장 크기의 정상범위를 제시하고, 신장과 체중에 따른 비종종대 기준의 상한치 조정이 필요한지 알아보고자 한다. 측정결과 남자 비장의 길이는 10.95±1.07 cm(8.9~13.9), 폭은 4.48±0.61 cm 이었으며, 여자 비장의 길이는 9.20±1.30 cm(6.8~12.0), 폭은 3.55±0.44 cm으로 남녀 간에 평균에 유의한 차이가 있었다(p<0.001). 신장의 크기가 증가할수록 비장의 길이는 증가하였으며(r=.57), 체중이 증가함에 따라서 비장의 길이가 증가하는 뚜렷한 양적 선형관계가 있었다(r=.63). 정상 성인에서 비장의 길이가 12cm를 초과한 남자는 5명, 여자는 2명 이었으며, 13cm를 초과한 경우는 남성 2명이었다.

일반적으로 간경변에 동반된 비장은 비대한 것으로 알려져 있다. 본 연구는 간경변을 보유한 환자의 복부 CT 영상을 이용하여 비장의 웨이브 패턴(wave patten)을 관찰하였는데 정상간을 보유한 사람의 복부 CT 영상과 차이가 있음을 발견하였다. 간경변을 가지고 있는 환자의 복부 CT 영상에서 비장은 왼쪽 측면에 깊은 웨이브 부분이 존재하였다. 정상간의 경우에도 왼쪽 측면에 웨이브가 존재하기도 하나 깊이가 깊지 않음을 알 수 있다. 그러므로, 간경변을 가진 비장의 웨이브 부분들의 면적의 합이 정상간을 가진 비장의 웨이브 면적보다 크다는 것을 알 수 있다. 나아가, 간경변을 보유한 영상에서 비장의 웨이브 부분을 추출하여 원형성(circularity)을 살펴보았을 때 정상간에 수반된 비장의 웨이브 부분보다 더 원형에 가깝다는 것을 알 수 있었다. 본 논문은 위와 같이 관찰된 원리를 바탕으로 복부 CT 영상에서 비장의 웨이브 패턴을 이용하여 비장 비대를 효과적으로 진단하는 새로운 방법을 제시한다. 이는 단순히 비장의 크기만을 이용하지 않고 비장의 형태 변화로써 국소적 비장 비대를 자동 판정해 낼 수 있음을 말해주는 것이다.

Objective : This study began with a recognition of the increase in internal disorders caused by functional impairment of the Spleen-Stomach(脾胃) due to modern dietary culture and environment. Method : Way of studying is select and analysis sentences which is include 'Stomach-Yin(胃陰)', 'Stomach-Jin(胃津)', 'Spleen-Stomach-Yin(脾胃陰)', 'Stomach-Yang(胃陽)', 'Spleen-Stomach-Yang (脾胃陽)' in Imjeungjinamuian(臨證指南醫案), and organize relevant paper. Result & Conclusion : In the history of the Spleen-Stomach Theory(脾胃學說), the theoretical mainstream was focused on On-yang(溫養), which was supplemented with methods of sweeten-cool-moisturize(甘凉濡潤) and communication-descent(通降法) by Ye, Tianshi(葉天士). Ye, Tianshi followed the academic theory of Li, Dongyuan(李東垣), putting emphasis on Stomach-gi(胃氣), along with some unique developments of his own. He specifically argued that the Spleen and Stomach be treated separately, and while accepting the methods of Li Dong-yuan in Spleen treatment, asserted that the Stomach-Yin be treated with medicinals with sweet/plain and sweet/cool/moist(甘平與甘凉濡潤) characteristics, and Stomach-Yang be kept firmly, as to prevent obstruction and reflux, by means of medicinals that communicate the Yang softly(通陽柔劑). As a result, the Yin-Yang(陰陽), Dryness-Dampness(燥濕) and Cold-Heat(寒熱) balance of the Yin-Jang (陰臟), Spleen and the Yang-Bu(陽腑), Stomach, the Stomach-Yin and Stomach-Yang was achieved both theoretically and in treatment by means of both communication and supplementation, adding accuracy to clinical application of the Spleen-Stomach Theory.
