Recently, with the development of advanced medical technology and the introduction of most advanced medical equipments, life expectancy increases accordingly. Many people want to live long-lived in health. Therefore, if it is possible to pre-diagnose the sub-health condition and formulate an appropriate treatment plan, we can prevent the disease and reduce social expenditure costs. In this study, we statistically analyzed the data in responding to each questionnaire for healthy biorhythm and sub-health among targeted members of a specific group. The analysis for the effects of healthy biorhythm to male and female showed that there was a significant difference between male and female. In the analysis of the effects of the conditions of healthy biorhythm to the 10 sub-health indicators, the significant effects of good and bad condition has been observed. The results of the decision tree analysis showed that all the respondents with poor hormone and urological sub-health status have bad healthy biorhythms. In summary, in this paper we have shown that it may be possible to improve the sub-health condition and prevent disease in advance if the healthy biorhythm is well controlled.

Objective : As for growth hormone(GH) secreting pituitary adenoma, it's remission should be declared on the basis of satisfactory controlling of the tumor, normalization of hormonal level, and symptomatic improvement of the patient. Several modalities of treatment have been applied and administered, and yet, this disease still remains as inveterate one to be fully treated. The purpose of this study is to evaluate the outcome of gamma knife radiosurgery(GKRS) for GH secreting pituitary adenoma, and to identify various factors affecting the outcome of the treatment. Method : A group of 24 out of 35 patients, treated by Leksell gamma knife unit during the period of March of 1992 through October of 1997, had been observed for more than two years. The mean target volume of microadenoma was $449.3mm^3(range 216-880mm^3)$, and that of macroadenoma was $3183.1mm^3(range 1456-13125mm^3)$. The tumor margin was covered with 50% isodose profile, and mean marginal dose was 25.2Gy(range 15-32.4Gy). The mean number of isocenter was 4.3(range 1-6). The exposed dose to the optic apparatus was less than 8Gy. The mean follow-up period was 37.8months(range 24-102months). Result : No patients showed any increase in the tumor volume during the follow-up period. And definite shrinkage of tumor volume(tumor volume reduction rate, TVRR : more than 50%) was obtained in 10 patients(41.7%). Twenty one patients(87.5%) had reduced hormonal level compared than pre-treatment level. Among them, normalization of the hormonal level was achieved in 12 patients(50%). Clinicoendocrinological remission was seen in 3 patients (12.5%). According to the results of statistical analysis, tumor volume(p=0.016),duration of symptoms(p=0.046), initial GH level(p=0.017), and the invasion of cavernous sinus(p=0.036) were significantly favorable to post-radiosurgical outcome. The TVRR was significantly related to post-radiosurgical reduction of serum GH level. Permanent complication was not seen. Conclusion : The authors concluded that GKRS is a safe and effective treatment modality for acromegaly. To otain the better outcome of GKRS in GH secreting pituitary adenoma, more careful and sophisticated treatment-planning is recommended.
Oriental medicine as a candidate for effective cancer treatment recently gain positive concerns in fields of therapeutic oncology. that is why some herbal medicines have been empirically safer in toxicity than anticancer drugs used in western medicine, and to show excellent therapeutic efficacy in human trial. Thus, these effects by clinically applied-herbs have not yet fully demonstrated in experimental tumor model. This study was initiated to evaluate the antitumor effect of Insambaekhaptang as candidate of antitumor-herbal agent against B16 melanoma metastasized into C57BL/6 mice lung. In experiment to test whether Insambaekhaptang can directly kill cancer cells in vitro or not, Insambaekhaptang showed direct killing action in concentration or higher against B16 melanoma cells using MTT assay, and showed lower IC50. Another experiment to know whether Insambaekhaptang can inhibit growth and metastasis of cancer cell or not, Insambaekhaptang significantly inhibited Solid tumor by intraperiperal injected-melanoma and lung metastasis induced by intravenous injected-melanoma in inbred C57BL/6 mice. When quantitative survival time increasing, we could obtain results that increased 113% in treated by Insambaekhaptang. These results show that Insambaekhaptang can inhibit growth of B16 melanoma cells through various biological mechanisms.

Kaposi's sarcoma was first descrided by Kaposi in 1872 as an idiopathic multiple hemorrhagic sarcoma. Its clinical features revealed to be erythematous red or purple macule started out, and developing into palpable dome-shaped nodules. Etiology is not defined to detail at present. Kaposi's sarcoma is classified to 4 categories; Classical, African, Epidemic and Immunosuppressive type. Epidemic categories is found approximately 20% of all AIDS patients and has strong predilection for head and neck region. The first case of immunosuppresive type Kaposi's sarcoma in patients with kidney transplants was reported in 1969. Kaposi's sarcoma accounts for 5% of all tumors associated with transplanted patients. The most common site of Kaposi's sarcoma in immunosuppressed patients are extremities, but rare in head and neck area. A 42 years old woman who had systemic lupus erythematosus visited to our clinic because of gingival hyperplasia, and excisional biopsy revealed Kaposi's sarcoma. We experienced a case of favorable results using excision and chemotherapy, so we report with review of literatures.
The Pancreatic islet are the clusters of endocrine cells scattered through out the exocrine pancreas. Transplantation of a sufficient pancreatic islets can normalize blood glucose level so that may prevent devastating complications of type I diabetes(IDDM) and other side effects of the IDDM. Recently, there are several approaches to transplant sufficient pancreatic islet, and it was comprised in increase or regeneration of the endogenous $\beta$-cell mass from donor's pancreas, but relatively few studies have been devoted to the morphological characters of the isolated and 3 day cultured pancreatic islets. We investigated morphological pattern of intracellular structure of isolated and 3 day cultured pancreatic islets. The morphological characters of the pancreatic islets were observed by scanning electron microscope and transmission electron microscope, and insulin distribution of the each islets were observed by transmission electron microscope, and were labeled with insulin antibody. Intracellular structures including nuclei, mitochondria, RER, Golgi complex and many secretory granules were normally appeared in the isolated pancreatic islets which was extracted immediately dornor's pancreas, however, There is a significant morphological changes between the 3 day cultured pancreatic islets and isolated islets. 3 day cultured pancreatic islet's $\beta$-cells had normal nuclei but increased cytoplasm mass and RER and developed Golgi complex. Insulin secretory granules were decreased in numbers rather than isolated pancreatic islet. In this study, the pattern of intracellular structure variation was examined during pancreatic islet culture. Most distinct features are variation of the insulin secretory granules, and developed RER, and dilated golgi complex. Therefore, we suggested that the various change of the morphological characters on cultured pancreatic islets were responsible for the function(biosynthesis and secretion of insulin) and growth. These results were also cultured islets have greater ability to recover and maintain normoglycemia than isolated islet transplantation.

5-Alpha reductase II, which converts testosterone (T) to dihydrotestosterone (DHT), is a crucial enzyme II in benign prostatic hyperplasia. Inhibitory effects of Curcuma longa L. (CL) extracts on 5-alpha reductase II activity were investigated in rat prostate tissue homogenates as well as LNCaP cells expressing human 5-alpha reductase II. Hot water extract (CL-HW) of Curcuma longa L. significantly inhibited 5-alpha reductase activity by over 80% at a concentration of $100{\mu}g/mL$, whereas 20% ethanol extracts (CL-E20) of Curcuma longa L. exhibited significant inhibitory activity from $50{\mu}g/mL$. These results indicated that Curcuma longa L is a potent 5-alpha reductase II inhibitor for benign prostatic hyperplasia treatment.

In a comprehensive summary use and supplementation of some well defined natural herbal formulations in the European swine breeding and fattening is documented. Along with this data also the quality assurance, hygenic as well as the standards of efficacy of the formulations are presented. Series of experimental and development work over the last several years with universities, research institutes, veterinarians and feed industry proved that the application of such phylo-components (feed supplementation) result in to optimizing swine breeding practices. On the basis of 4 specific formulations tested and used in the European veterinary field most of the common problems of pig breeding and rearing can be successfully handled. Precisely, problems of fertility, respiration, diarrhea and stress; which are directly related to imerse losses in production, with poor quality of piglets associated with immune suppressions. Besides curing common symptoms, one of the most important aspect is of improvement in the self defence mechanism which results ultimately in to increased immunity, vitality and health of the animals; of course, thereby reducing the mortality which is the most economical problem observed in the animal health. Moreover, data presented here reflects on the fact that the use of such high quality alternative formulations successfully replace conventionally used antibiotics or hormonal therapies. They also work synergestically of as complementary in vaccination program or act as growth promoting agents on natural basis.
Ghrelin is a 28 amino acid orexigenic peptide hormone that is secreted predominantly by tX/A cells in the stomach, and it plays a major role in energy homeostasis. Activated ghrelin has an n-octanoyl group covalently linked to the hydroxyl group of the Ser3 residue, which is critical for its binding to the G-protein coupled growth hormone secretagogue receptor-1a (GHS-R1a). According to recent reports, both ghrelin and its receptor, GHS-R1a, are expressed by a variety of immune cells, including T- and B-lymphocytes, monocytes, and dendritic cells, and ghrelin stimulation of leukocytes provides a potent immunomodulatory signal controlling systemic and age-associated inflammation and thymic involution. Here, we report that ghrelin protected murine thymocytes from dexamethasone (DEX)-induced cell death both in vivo and in vitro. Subsequently, we explored the molecular mechanisms of the antiapoptotic effect of ghrelin. According to our experiments, ghrelin inhibited the expression of proapoptotic proteins via the regulation of glucocorticoid receptor (GR) phosphorylation. As a result, ghrelin inhibited the proapoptotic activation of proteins, such as Caspase-3, PARP, and Bim. These data suggest that ghrelin, through GHS-R, inhibits the pathway to apoptosis by regulation of the proapoptotic protein activation signal pathway. They provide evidence that blocking apoptosis is an essential function of ghrelin during the development of thymocytes.

GLP-1-based drugs (GLP-1 analogues and DPP IV inhibitors) and incretin mimetics are currently one of the most exciting classes of agents for type II diabetes. GLP-1, a gut peptide, is an incretin that potentiates glucose-dependent insulin release from the pancreas, slows GI-transit and stimulates the proliferation of beta-cells. DPP IV inhibitors act like incretins by inhibiting DPP IV which inactivates GLP-1. LC15-0133 is a competitive, reversible DPP IV inhibitor ($IC_{50}$ = 24 nM, Ki=0.247 nM) with excellent selectivity over other critical human proteases such as DPP II, DPP 8, elastase, trypsin. and urokinase. LC15-0133 showed long half-life and good bioavailability in rats and dogs. Inhibition of plasma DPP IV activity by LC15-0133 was kept more than 50% 24 hours after oral dosing in rats and dogs at 0.1 mg/kg and 0.02 mg/kg, respectively. The Minimum effective doses of LC15-0133 were 0.01 mg/kg for lowering blood glucose excursion during oral glucose tolerance test and 0.1 mg/kg for increasing glucose-induced GLP-1 response in C57BL/6 mice. Repeat oral administration of LC15-0133 for 1 month delayed the progression to diabetes and reduced HbA1c levels in a dose-dependent manner in Zucker Diabetic Fatty rats. In conclusion, LC15-0133 is a novel, potent, selective and orally active DPP IV inhibitor and showed an excellent blood glucose lowering effects in various animal models.

To evaluate the possible therapeutic effects of growth hormone and vitamin C on multiorgan failure, a rat model was developed for LPS-induced sepsis. Using this model, the effects of growth hormone and vitamin C on tissue damages, catalase and i-NOS activities, and MDA levels were examined in the lung and liver. The level of TNF- in plasm was also examined. Male, Sprague-Dawley rats were injected with LPS intraperitoneally then divided into 3 groups : positive controls injected with LPS only, the ones injected with growth hormone or vitamin C immediately after the LPS injections. The lung and the liver were then isolated, blood samples were collected at 24 or 48 hours after the LPS injection, then examined for histopathological and biochemical changes. The results obtained were as follows. 1. LPS induced sinusoid vasodilation and mild destruction of lobular structure in the liver. In the lung, alveolar structure appeared to be thickened and interstitial edema was observed. The levels of MDA in the liver and the lung was increased by LPS, while the activity of catalase was decreased. The activity of i-NOS of those tissues was also increased, which was more pronounced at 24 hr. The level of TNF- in plasm was increased by LPS 2. In the lung, vitamin C suppressed lymphocyte and neutrophil infiltration, alveolar wall thickening and interstitial edema. In the liver, vitamin C protected against the destruction of the lobular structure. The activity of catalase reduced by LPS was reversed partly by vitamin C. The activity of i-NOS enhanced by LPS was also reversed by vitamin C. The level of TNF- in plasm reduced in some animals by vitamin C, which however was not significant statistically(p<0.05). 3. Growth hormone showed similar protective effects against inflammation and damages in the liver and lung tissues. Growth hormone reversed partly the LPS effects on the level of MDA, the activity of catalase and i-NOS induction in the liver and the lung. Growth hormone reduced plasma level of TNF-${\alpha}$ substantially, which contrasted from vitamin C. Besides this, overall protective effects of growth hormone against LPS-induced experimental sepsis were similar to those of vitamin C. From this results, the mechanism of growth hormone on suppression of LPS-induced tissue damage might be associated with production of antioxidative enzyme and suppression of plasma TNF- level.
