The heart takes the top position as the monarch of the physiological activity in five viscera and six bowels. Activity to think and ponder, or harmony of the function of viscera and bowels and passing smoothly of qi and blood and so on, these depend on the function of heart. So it is called the center of life activity. This thesis studied bibliographically the process of formation of the system of differention of syndromes. First, in the classify of deficiency syndrome, insufficiency of the Heart is classified deficiency of the Heart-yin and insufficiency of the Heart-yang. After it classified insufficiency of the Heart-qi, insufficiency of the Heart-yang, dificiency of the 'Heart-blood and deficiency of the Heart-yin. At lately it classified more subdivide into insufficiency of the Heart-qi, insufficiency of the Heart-yang, dificiency of the Heart-blood, deficiency of the Heart-yin. Deficiency of the Heart-qi yin, deficiency of the Heart-qi blood, deficiency of the Heart-yin yang and sudden exhaustion of the Heart-yang. Second, It were the most important that the phlegm, fire and heat in the classify of excess syndrome. It classified various differentiation of syndrome. In the beginning of a period, it only classified phlegm syndrome and heat syndrome, but recently it classified not only phlegm syndrome and heat syndrome but also phlegm-fire. Also, It classified importantly gradually Heart-blood stasis caused by deficiency of the Heart-qi and the Heart-yang. Variety and subdivision of classify of differentiation of syndrome seemed resault of study to prepare various disease. And that after demanded more and more positive study.

Craniosynostosis, the premature fusion of cranial sutures, presumably involves disturbance of the interactions between different tissues within the cranial sutures. Interestingly, point mutaions in the genes encoding for the fibroblast growth factor receptors(FGFRs), especially FGFR2, cause various types of human craniosynostosis syndromes. To elucidate the function of these genes in the early morphogenesis of mouse cranial sutures, we first analyzed by in situ hybridization the expression of FGFR2(BEK) and osteopontin, an early marker of osteogenic differentiation, in the sagittal suture of calvaria during embryonic(E15-E18) and postnatal stage(P1-P3). FGFR2(BEK) was intensely expressed in the osteogenic fronts, whose cells undergo differentiation into osteoprogenitor cells that ultimately lay down the bone matrix. Osteopontin was expressed throughout the parietal bones excluding the osteogenic fronts, the periphery of the parietal bones. To further examine the role of FGF-mediated FGFR signaling in cranial suture, we did in vitro experiments in E15.5 mouse calvarial explants. Interestingly, implantation of FGF2 soaked beads onto both the osteogenic fronts and mid-mesenchyme of sagittal suture after 36 hours organ culture resulted in the increase of the tissue thickness and cell number around FGF2 beads, moreover FGF4-soaked beads implanted onto the osteogenic fronts stimulated suture closure due to an accelerated bone growth, compared to FGF4 beads placed onto mid-mesenchyme of sagittal suture and BSA control beads. In addition FGF2 induced the ectopic expression of osteopontin and Msx1 genes. Taken together, these data indicate that FGF-mediated FGFR signaling has a important role in regulating the cranial bone growth and maintenance of cranial suture, and suggest that FGF-mediated FGFR signaling is involved in regulating the balance between the cell proliferation and differentiation through inducing the expression of osteopontin and Msx1 genes.

Objectives : To satisfy the demand of good treatment of constipation Methods : we investigated the literatures of Oriental Medicine about Constipation. Results: 1. There are three categories of etimological factors of constipation, that is, endogenous, exogenous and non-exo-endogenous factor. The endogenous factor is caused by seven emotions, called depression of Ki and stagnation of Ki. The exogenous factor is six excessive atmospheric influences, for example, wind, cold, dampness, heat and dryness. And the non-exo-endogenous factors are overfatigue, improper diet, stagnated blood and deficiency of Ki and blood that comes from old age, long disease and after delivery. 2. Classification: According to cause of disease it is classified by constipation due to cold, heat, wind, dryness, retention of undigested and phlegm. According to Internal Organs there are constipation due to deficiency syndrome of the stomach, excess syndrome of the stomach, deficiency syndrome of kidney and splenic constipation. And Differentiation of syndromes according to Ki and blood, there are constipation of deficiency type and excess type. There are constipation due to stagnation and deficiency of Ki, deficiency of blood and stagnated blood. 3. Principles and Methods of treatment 1) Herbal Medicine (1) Excess type [1] Constipation due to heat : Seunggitang(承氣湯) and Majainwhan(麻子仁丸) [2] Constipation due to stagnation of Ki : Samatang(四磨湯) and Yukmatang(六磨湯) (2) Deficiency type [1] Constipation due to deficiency of Ki : Whanggitang(黃?湯) [2] Constipation due to deficiency of blood: Yunjangwhan(潤腸丸) [3] Constipation due to cold : Jechunjun(濟川煎) and Banyuwhan(半硫丸) 2) Enema therapy: It is a method to induce defecation by honey or pig's bile juice for weak people. 3) Acupuncture and Moxibustion: Acupoints used to treat constipation are BL25, ST25 and TE6. Moxibustion at CV8, CV6 is good for constipation due to cold. (4) Diet therapy: It is very important that we eat meals regularly and defecate on the same time even if you don't. And we have to eat food like fruits, vegetables and beans. (5) finger pressure: Finger pressing around these points like ST25, SP25, BL25, BL31, BL32, BL33 and BL34 is good for it. (6) Kigong therapy: Abdominal breathing (7) Old man' s constipation: Hip bath or diet therapy is commended. Laxation with lubricant like Supungyunjangwhan(搜風潤腸丸) is used. (8) Women' s constipation: After delivery, we have to administer tonifying prescription Sipjundaebotang(十全大補湯) and enema can be used. Conclusion : We have to examine the cause of disease and bowl movement carefully. After comprehensive analysis of the data gained by the four methods of diagnosis, we diagnose and treat patients on the base of overall of symptoms and signs.

Adipogenesis as a model system is needed to understand the molecular mechanisms of human adipocyte biology and the pathogenesis of obesity, diabetes, and other metabolic syndromes. Many relevant studies have been conducted with a focus on gene expression regulation and intracellular signaling relating to Peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT/enhancer-binding protein alpha (C/EBPα), which are master adipogenic transcription factors. However, epigenome regulation of adipogenesis by epigenomic modifiers or histone mutations is not fully understood. Histone methylation is one of the major epigenetic modifications on gene expression in mammals, and histone H3 lysine methylation (H3Kme) in particular implicates cell differentiation during various tissue and organ development. During adipogenesis, cell type-specific enhancers are marked by histone H3K4me1 with the active enhancer mark H3K27ac. Mixed-lineage leukemia 4 (MLL4) is a major H3K4 mono-methyltransferase on the adipogenic enhancers of PPARγ and C/EBPα loci. Thus, MLL4 is an important epigenomic modifier for adipogenesis. The repressive mark H3K27me3 is mediated by the enzymatic subunit Enhancer zeste homolog 2 (EZH2) of the polycomb repressive complex 2. EZH2-mediated H3K27 tri-methylation on the Wnt gene increases adipogenesis because WNT signaling is a negative regulator of adipogenesis. This review summarizes current knowledge about the epigenomic regulation of adipogenesis by histone H3 lysine methylation which fundamentally regulates gene expression.
