Diseases caused by indurate tissues of the internal organs are liver cirrhosis and abdominal sclerosis. The cause of chronic gastro-intestinal disease is a digestive system disorder and a defecation disorder. They impede peristaltic movement and digestive system with the symptom that indurate tissues. The purpose of the present study was to determine the disease grade quantitatively by measuring an indurated standard of tissues and organs. For the measurement of elasticity, we designed the system that measure the displacement of the substance and approved pressure using ultrasound transducer. For verification of developed system, we compared elasticity as results of experiment between the developed system and public elasticity measurement machine at individual plastic phantoms made by plastic hardener and softener. Elasticity of the plastic phantoms is averagely 0.007MPa lower measured by developed system than Micro-indenter, and less than 10% errors. Comparing with economical value and accuracy between developed system and Micro-indenter, the system is significant of measurement for tissue elasticity. Thus, it is possible to measure a elasticity at human tissue and organ. A chronic gastro-disease as well as grade could be decided objective validity using this system.

Objectives: This study was carried out to observe the foot gworeum meridian muscle from a viewpoint of human anatomy on the assumption that the meridian muscle system is basically matched to the meridian vessel system as a part of the meridian system, and further to support the accurate application of acupuncture in clinical practice. Methods: Meridian points corresponding to the foot gworeum meridian muscle at the body surface were labeled with latex, being based on Korean standard acupuncture point locations. In order to expose components related to the foot gworeum meridian muscle, the cadaver was then dissected, being respectively divided into superficial, middle, and deep layers while entering more deeply. Results: Anatomical components related to the foot gworeum meridian muscle in human are composed of muscles, fascia, ligament, nerves, etc. The anatomical components of the foot gworeum meridian muscle in cadaver are as follows: 1. Muscle: Dorsal pedis fascia, crural fascia, flexor digitorum (digit.) longus muscle (m.), soleus m., sartorius m., adductor longus m., and external abdominal oblique m. aponeurosis at the superficial layer, dorsal interosseous m. tendon (tend.), extensor (ext.) hallucis brevis m. tend., ext. hallucis longus m. tend., tibialis anterior m. tend., flexor digit. longus m., and internal abdominal oblique m. at the middle layer, and finally posterior tibialis m., gracilis m. tend., semitendinosus m. tend., semimembranosus m. tend., gastrocnemius m., adductor magnus m. tend., vastus medialis m., adductor brevis m., and intercostal m. at the deep layer. 2. Nerve: Dorsal digital branch (br.) of the deep peroneal nerve (n.), dorsal br. of the proper plantar digital n., medial br. of the deep peroneal n., saphenous n., infrapatellar br. of the saphenous n., cutaneous (cut.) br. of the obturator n., femoral br. of the genitofemoral n., anterior (ant.) cut. br. of the femoral n., ant. cut. br. of the iliohypogastric n., lateral cut. br. of the intercostal n. (T11), and lateral cut. br. of the intercostal n. (T6) at the superficial layer, saphenous n., ant. division of the obturator n., post. division of the obturator n., obturator n., ant. cut. br. of the intercostal n. (T11), and ant. cut. br. of the intercostal n. (T6) at the middle layer, and finally tibialis n. and articular br. of tibial n. at the deep layer. Conclusion: The meridian muscle system seemed to be closely matched to the meridian vessel system as a part of the meridian system. This study shows comparative differences from established studies on anatomical components related to the foot gworeum meridian muscle, and also from the methodical aspect of the analytic process. In addition, the human foot gworeum meridian muscle is composed of the proper muscles, and also may include the relevant nerves, but it is as questionable as ever, and we can guess that there are somewhat conceptual differences between terms (that is, nerves which control muscles in the foot gworeum meridian muscle and those which pass nearby) in human anatomy.

There are eight kinds of formulas for invigorating the liver to cure its asthenic syndrome based on the types of preparation formulas Began-tang, Boganhwan, Bogansan, Bogandan, Boganeum, Boganjoo, Boganjeon and Bogango. Another formula called Bocheonghwan is to invigorate the green colour of liver. There are 22 kinds of Bogan-tang, 12 kinds of Boganhwan, 25 kinds of Bogansan, one kind of Bogandan, one kind of Boganeum, one kind of Boganjoo, one kind of Boganjeon, one kind of Bogango, and two kinds of Bocheonghwan. Combination of herbal medicines, carried out in formulas for invigorating the liver, consists of various kinds depending on medical scientists' personal experience in medical treatment without any general principles, which makes it difficult to apply it to clinical use. The objectives of this study lie in theoretical establishment of Bogan-tang for curing the asthenic syndrome of liver through analyzing the component medicines and combination principles of Hyeongok's Bogan-tang, and furthermore, maximizing the clinical use of Began-tang. This study analyzed the component medicines and combination principles of Hyeongok's Bogan-tang based on the theory for properties and tastes of herbal medicines from the ${\ulcorner}$yellow Emperor's Canon of Internal Medicine${\lrcorner}$ , the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine, and the five elements doctrine. Hyeongok's Began-tang is an odd prescription, composed of 7 kinds of ingredients No.1 Radix Angelicas Sinensis (2don;7.5g), No.2 Rhizoma Chuanxiong (1don;3.75g), No.3 Radii Polygoni Multiflori (1don), No.4 Fructus Lycii (1don), No.5 Cortex Cinnamomi (1don), No.6 Rhizoma Gastrodiae (1don), and No.7 Radix Glycyrrhizae (1don). There are three methods for curing the asthenic syndrome of liver according to the five elements doctrine invigorating the liver, invigorating the kidney and purging the lung. First, if you suffer from the asthenic syndrome of the liver, you need to invigorate your liver. There are two available methods, including taste and property invigoration according to the theory for properties and tastes of herbal medicines. They each imply the pungent taste and the warm property invigorate the liver. In the case of taste invigoration, two herbal medicines with pungent taste, Radix Angelicas Sinensis and Rhizoma Chuanxiong, are combined into the principal and assistant herbal medicine, respectively. For property invigoration, two herDal medicines with the warm property, Cortex Cinnamomi and Rhizoma Gastrodiae, are combined into adjuvant herbal medicines. Secondly, if you suffer from the asthenic syndrome of the liver, you need to invigorate your kidney which is mother in the mother-child relationship in inter-promotion among the five elements. There are two methods to invigorate the kidney, including taste and property invigoration according to the theory for properties and tastes of herbal medicines. They each mean the bitter taste and the cold property invigorate the kidney. Therefore, it is important to use bitter herbal medicines for taste invigoration and cold ones for property invigoration. Both Differ and cold herbal medicines, Radix Polygoni Multiflori and Fructus Lycii, are combined into adjuvant herbal medicines. Lastly, if you suffer from the asthenic syndrome of the liver, you need to purge your lung which is an element being surpassed in the relationship between the elements surpassed and ones not surpassed in inter-restraint among the five elements. There are two methods to purge the lung, which include taste and property invigoration according to the theory for properties and tastes of herbal medicines. Taste invigoration means to purge the lung with pungent taste and property invigoration to purge the lung with warm property. Therefore, it is important to use pungent herbal medicines for taste invigoration and warm ones for property invigoration. Both pungent and warm herbal medicines, Radix Angelicas Sinensis and Rhizoma Chuanxiong, were combined to invigorate and purge the lung. In addition, Radix Glycyrrhizae are combined as dispatcher herbal medicine, harmonizing all the herbal medicines composing the formula. First, to cure the asthenic syndrome of the liver, the methods of invigorating the liver and the kidney, and purging the lung should be used according to the five elements doctrine. Secondly, herbal medicines appropriate for those treatment methods should be chosen according to the theory for properties and tastes of herDal medicine and thirdly, the combination of those herbal medicines should be carried out according to the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine. As a good example, Hyeongok's Bogan-tangon is combined according to the above theories. In conclusion, this formula was created by applying to the theory for properties and tastes of herbal medicines.

This thesis is a study on the diagnostic theory and methods of Macjin(checking of pulse) as described in the Whang Di Nei Qing. There are four methods of Macjin in this text, namely: Dong Macjin(動脈法), Sam Bu Gu Who Macjin(三部九脈診). In Young Gi Gu Macjin(人迎氣口脈診法), Nei Qing's Gi Gu Macjin(內徑의 氣口脈法). Each method developed in it's own way, but they are all closely related and became the basis of today's Macjin. I examined the methods of Macjin in the Whang Di Nei Qing from a perspective of "change". The main questions of this study are: "What brought about the development of the different methods?". "How do the methods differ?", and "how did these methods evoke into today's Macjin?". The method of Macjin generated spontaneously from the observation and treatment of disease. Dong Macjin was the first method developed and became the basis of subsequent forms of Macjin. The accumulation of medical knowledge and the influence of oriental philosophy fueled the evolution of Macjin. Chronologically, Macjin methods developed starting with Dong Macjin and eventually into Sam Bu Gu Who Macjin. In Young Gi Gu Macjin, and Nei Qing's Gi Gu Macjin. The different methods of Macjin vary in how many pulse points are checked, and were established with simplicity and effectiveness in mind. Dong Macjin involves the checking the whole body. Sam Bu Gu Who Macjin involves nine points. In Young Gi Gu Macjin involves four points. and Nei Qing's Gi Gu Macjin involves two. In it's early development, the checking of a patient's pulse was used to diagnose only localized disorders in comparison with symptoms. It evolved with Oh Jang Mad(五臟脈, five main types of pulse) to be able to check internal organs with the introduction of Nei Qing's Gi Gu Macjin. After the division of Chon Kwan Chuck(寸關尺), it evolved further to be able to make a detailed diagnosis by using the result of pules checks. Nowadays, we can make 28 forms of diagnostic indices from these development. In conclusion, Macjin can be used practically and effectively in the diagnosis of disease. In using three methods of Macjin(In Young Gi Gu Macjin, Nei Qing's Gi Gu Macjin, and today's Gi Gu Macjin, which can determine the whole body's Siate of well-being) in conjunction with Dong Macjin(which helps pinpoint the localized disorder), an exact diagnosis can be obtained. I strongly feel that we should acquire objectivity by accommodating Macjin with modern methods of medicine.

Low-fat and sugar-free (LFSF) cookies were developed for patients with metabolic syndrome X, such as obesity, diabetes, coronary heart disease, and hypertention, using artificial sweeteners (mixture of aspartame and saccharin), pectin and herb extracts such as Polygonatum Odoratum (Mill) Druce, Schizandrae Fructus and Lycii Fructus, without sugar and fats. LFSF cookies were composed of 7.5 : 1 of aspartame and saccharin, 5% pectin, 49% protein, and 5% herb extracts, with reduced fat level. The values for area under the curve in oral glucose tolerance tests were significantly lower in 90% pancreatomized-(Px, n = 8) and sham - operated (Sham, n = 8) rats which consumed LFSF cookies, than the control, which consumed regular cookies. Blood glucose levels were higher and the peak levels were significantly lower in the LFSF cookies group than the control group of Px and Sham rats. Blood glucose levels of healthy female college students (n = 10) at 30 and 60 min after the consumption of 30 g LFSF and regular cookies were not different, but they were significantly lower in the LFSF-cookies group in diabetes patients (n = 10). In conclusions, LFSF cookies was considered as a good snack for diabetic patients.

Objective : Moutan Cortex (the root bark of Paeonia suffruticosa Andr.) is widely used in oriental medicine as a remedy for inflammation. However, as yet there is no clear explanation of how MC(Moutan Cortex) affects the production of inflammatory cytokine. This study was to determine the effects of Essence extracted MC on the mast cell-mediated inflammatory responses. Method : We observed the effect of MC on compound 48/80-induced histamine release of rat peritoneal mast cells and the effect of administering MC on PCA in rat. We measured the amount of inflammatory cytokine production induced by the phorbol myristate acetate (PMA) plus calcium ionophore(A23187) in the human mast cell line (HMC-1) incubated with various concentrations of MC. The TNF-$\alpha$ protein levels were analysised by Western blot. The TNF-$\alpha$, IL-6 and IL-8 secreted protein levels were measured by the ELISA assay. The TNF-$\alpha$, IL-6 and IL-8 mRNA levels were measured by the RT-PCR analysis. NF-$\kappa$B, phospho-I$\kappa$B and MAPKs were exmined by Western blot analysis. The NF-$\kappa$B promoter activity was examined by luciferase assay. Result : 1. Enzyme immunoassay indicated that MC suppressed histamine secretion of rat peritoneal mast cells. 2. In PCA dependent on IgE, MC had anti-allergic effect of the internal surface of rat skin. 3. Western blot indicated that MC decreased TNF-$\alpha$ protein levels. 4. ELISA indicated that MC decreased TNF-$\alpha$, IL-6 but MC had no significant effect on IL-8 in HMC-1 cells. 5. RT-PCR indicated that MC decreased TNF-$\alpha$, IL-8 but MC had no significant effect on IL-6 in HMC-l cells. 6. Western blot indicated that MC suppressed the induction of MAPKs, NF-$\kappa$B & phospho-I$\kappa$B activity in HMC-1 cells. 7. Luciferase assay indicated that MC suppressed the PMA plus A23187-induced NF-$\kappa$B promoting activityin HMC-1 cells. Conclusion : In this study, we have found that MC is an inhibitor of NF-$\kappa$B, MAPKs & cytokines on the mast cell-mediated inflammatory responses.

Background and Objectives : Allergic Contact Dermatitis is the disease affected by industrialization. The more industrialization advanced, the more materials that could induce the allergic contact dermatitis have been increased. Therefore in oriental medicine, various studies have been performed. The objective of this study is to investigate the effects of Naetakchunkeum-san on the Allergic Contact Dermatitis induced by 2,4-dinitro-chlorobezene(DNCB). Meterial and Methods : Twenty eight mice were divided into four groups ; normal, control, experimental group A and B. Control and experimental group were induced allergic contact dermatitis by DNCB. Experimental group A was orally administered the Naetakchunkeum-san and experimental group B was orally administered the prednisolone. In this study, ear thickness measurement, observation auricle microphotograph, Myeloperoxidase(MPO) activity measurement, Reverse transcription-polymerase chain reaction(RT-PCR) analysis of the mRNA level of $TNF-\alpha$, $IL-1\beta$, $INF-\gamma$ were performed on these four groups. In addition, the effect of Naetakchunkeum-san on cell viability and the effect of Naetakchunkeum-san on the compound 48/80-induced histamine release from HMC and RPMC were measured, Results : 1. In contact hypersensitivity assay, experimental group A and B showed decreased ear thickness compared with control group, 2. In experimental group A, pathological lesion of dermatitis were alleviated. In addition, the numbers of infiltrated cells were reduced, and cleft was not shown compared with control group, In experimental group B, similar results were shown. 3. There was a significant increase in MPO activity in control group compared with normal group, Experimental group A and B significantly inhibited the increase in MPO activity compared with control group. 4, The level of expression of $TNF-\alpha$, $IL-1\beta$, $INF-\gamma$ in experimental group A and B were significantly lower than those in control group. As the internal control, cyclophilin mRNA was also reverse-transcribed and amplified. 5, In MTT assay, there were no statistically significant differences in 100 ${\mu}g/ml$, 200 ${\mu}g/ml$, 500 ${\mu}g/ml$, 1000 ${\mu}g/ml$ Naetakchunkeum-san treated group from 0 ${\mu}g/ml$ Naetakchunkeum-san treated group as determined by the Tukey test. 6. Naetakchunkeum-san dose-dependently inhibited the compound 48/80-induced histamine release from both HMC and RPMC. Conclusions : According to above experiments, Naetakchunkeum-san may be applied to allergic contact dermatitis.

Arctigenin is the main active ingredient of Fructus Arctii, which has been reported with a variety of therapeutic activities including anti-cancer, anti-inflammation, anti-virus, and anti-obesity effects. In this study, a simple and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the determination of arctigenin in rat plasma. The assay utilized a simple protein precipitation with methanol and the mobile phase consisted of 100% methanol and water containing 0.1% formic acid (65:35 v/v). Arctigenin and the internal standard (psoralen) were monitored using a positive electrospray turbo ionspray mode with multiple reaction monitoring transitions of m/z $373.2{\rightarrow}136.9$ and m/z $187.2{\rightarrow}130.9$, respectively, and total chromatographic run time was within 5 min. The lower limit of quantification (LLOQ) of arctigenin was 5 ng/mL in the rat plasma. The intra- and inter-day accuracy of arctigenin at LLOQ and matrix-matched quality control samples ranged 97.4 - 104.8% and 97.2 - 102.0%, respectively. The intra-day precision was within 4.80% and the inter-day precision was within 5.92%. Application of the present method was demonstrated through a pharmacokinetic study after intravenous and oral administration of arctigenin in male Sprague Dawley rats.

Purpose : To investigate the effects of the lavender, lemon and eucalyptus oil mixture on the atopy dermatitis skin lesions induced on NC/Nga Mice by dinitrochlorobenzene (DNCB). Material and Method : For this purpose, we fabricated the oil mixture blending three essential oils (lavender, lemon, eucalyptus : ELL) with one carrier oil (jojoba) and apply it on the atopic dermatitis skin lesions of NC/Nga Mice. Atopic dermatitis in NC/Nga Mice was induced by DNCB treatment on the dorsal skin of mice for 8 weeks. The mixture of ratio of each essential oil drop was 1 (eucalyptus) : 2 (lemon) : 2 (lavender) and this mixture was blended with jojoba oil 50ml (0.025%). The ELL-ointment was supplied for 8 weeks. We evaluated the effects of ELL on cell viability of mouse lung fibroblast, clinical skin features and severity, the level of serum Immunoglobulin (Ig) E & Ig G1, Interleukin (IL)-4, IL-13 and Interferon (IFN)-$\gamma$. Results : ELL showed safety on the cell viability of mouse lung fibroblast compared with control group. The cell viability was measured by SRB method. The effects of ELL on clinical skin features and severity in DNCB-induced dermatitis model of NC/Nga mice was significant compared with control group. EEL also showed significant effects on clinical symptom score compared with control group. Serum IgE & IgG1 level and development of atopy dermatitis skin lesions were evaluated. Serum IgE & IgG1 production was significantly down-regulated in EEL group compared with control group. ELL also down-regulated the levels of IL-4 and IL-13, and up-regulated the level of IFN-$\gamma$ compared with control group significantly. Conclusion : ELL was effective on atopy dermatitis by modulating Th2 related factors.

In order to investigate the effects of ethylene on the seed development of three corn types (dent, sweet, and super sweet corns), aminoethoxyvinyl glycine (AVG) and silver thiosulfate (STS) and ethephon (2-chloroethylphosphonic acid, CEPA) were applied either on whole plants or shanks of ears at 9 and 21 days after silking. Ethylene production of developing super sweet corn seeds was much higher than those of sweet and dent corns. The cavity in the endosperm tissues of the super sweet corn started earlier and endosperm was collapsed more severely compared to those of sweet and dent corns. Ethylene production seemed to be related to the death of endosperm cells to form a cavity. Application of AVG and STS reduced ethylene production and delayed cavity formation in endosperm of super sweet corn seeds, while CEPA increased ethylene production and enhanced the time of cavity formation. AVG and STS increased 100-seed weight, while CEPA decreased.
