This research was planned and executed to evaluate how the composition of Yack-sun tea can affect the health conditions of people who are suffering from diet-related such as being overweight, are obese and have hyperlipidemia, by taking Yack-sun tea in a form of a nutritional supplement with our daily meals. We produced Kangjieum with Lycium chinense Mill., Polygonum multflorum Thunb, Cassia tora L., Crataegus pinnatifida Bge and Salvia miltiorrhiza Bge. Thus, we approach of oriental diet therapy area research of Kangjieum and analysis proximate composition, water soluble antioxidant content. The content(%, dry basis) of total carbohydrate was 60.23%, crude protein was 18.18%, crude ash was 11.36% and crude fat was 10.23% in Kangjieum. Total water soluble antioxidant content was 1.027 ${\mu}g/m{\ell}$ of Kangjieum. We think that scientific and objective evaluation was done on the components of the Kangjieum prescription. This basic data could help guide the application of oriental medicinal resources into other foods and serve as a stepping-stone for use of Kangjieum in the burgeoning field of nutraceutical foods. Last, the scientific effects of oriental medicinal foods developed according to oriental medicinal theory. This theory is believed to be essential for government policy development concerning validation of medicinal effects and assessment, with the aim of fostering systematic development and providing guidance to food development in the interest of national health.

Purpose: This study examined the influence of the maximal aerobic capacity on the two-year cardiac-related re-hospitalization in patients with heart failure with a reduced ejection fraction (HFrEF) in Korean society. Methods: The maximal aerobic capacity of the study population (n=95, male 63%) was evaluated using a cardiopulmonary exercise (CPX) testing system. Each patient was followed up for two years to divide the HFrEF patients into two groups according to cardiac-related re-hospitalization: re-hospitalization (RH) group (n=29, 30%) and no re-hospitalization (NRH) group (n=66, 70%). Results: The relative peak $VO_2$ (mL/kg/min, p<0.001), exercise duration (p<0.001), respiratory exchange ratio ($VCO_2/VO_2$, p=0.001), systolic blood pressure (SBP) reserve (p=0.004), heart rate (HR) reserve (p=0.007), SBP max (p=0.02), and HR max (p=0.039) were significantly lower in the RH group than the NRH group during the CPX test. On the other hand, the ventilatory efficiency (VE/VCO2 slope, p=0.02) and age (p=0.022) were significantly higher in the RH group than in the NRH group. In binary logistic regression analysis, the relative peak $VO_2$ (p=0.001, Wald Chi-square 10.137) was the strongest predictive factor on cardiac-related re-hospitalization, which was followed by $VCO_2/VO_2$ (p=0.019, Wald Chi-square 5.54). On the other hand, age (p=0.063, Wald Chi-square 3.445) did not have a significant influence on cardiac related re-hospitalization. Conclusion: The maximal aerobic capacity, especially the relative peak $VO_2$, is the strongest factor on cardiac-related re-hospitalization within two years in patients with HFrEF in Korean society.

The object of this study was to develop a gene therapy strategy for ovarian cancer. We have previously shown that AV with a L-plastin (LP) promoter infects breast and ovarian cancer cells and expressed ${\beta}$-galactosidase cDNA in preference to normal fibroblast cells and hematopoietic cells. We now report on the cytotoxicity of Ad.LP.CD, an AV carrying a CD cDNA which converts the pro-drug, 5-Fluorocytosine (5-FC) into the toxic drug 5-Fluorouracil (5-FU). Infection of Ad.LP.CD into either 293 cells or ovarian cancer cells generated the functional CD as measured by HPLC analysis. Using a ratio of AV to OVCAR3 cell of 100 and a 5-FC concentration of 100 ${\mu}$M, we achieve an over 95 % of cell growth inhibition. We are using flow cytometry analysis for ${\beta}$ -galactosidase and ovarian cancer associated folate receptor to screen primary ascites samples for infectivity after infection with an adenoviral vector, i.e., Ad.LP.LacZ. This vector system may be of value in the treatment of microscopic disease of ovarian cancer in the peritoneal cavity.

As a possible step to evaluate in the mammary gland the role of motherwort (Leonurus sibiricus L), a representative medicinal plant used traditionally for the therapy of gynecologic diseases, the effects of the agent on lactation which was suppressed by preganacy-dependent mammary tumors (PDMT) were studied in GR/A mice. Beginning the day of placing with males at 45-50 days of age, female mice were given 60% methanol-extract of the aerial part of motherwort as drinking water at the concentration of 0.5% throughout the experiment. Mice developing PDMT during pregnancy [PDMT(+)] and given motherwort were similar to mice developing no PDMT [PDMT(_)] with or without motherwort treatment and were significantly higher than PDMT(+) mice given tap water in litter growth and mammary RNA/DMA ratio on day 12 of the 2nd lactation. Mammary DNA and RNA contents were also elevated by motherwort in PDMT(+) mice. The results suggest that motherwort can ameliorate lactation suppressed by PDMT through its stimulation of both growth and function of the mammary glands.

Between June 1988 and June 1994, twenty five patients with locAlly advanced esophageal carcinoma received preoperative chemotherapy (Cisplatln, 5-Fluorouracil with or without Etoposide) and followed by resection. All patients had clinical evidence of airway involvement or distant Iymphnode involve- ment (M 1 Iymphnode) on bronchoscopy or computed tomographic scans. The major response rate to chemotherapy decided by the postoperative stage was 48% (12125). The resection rate was 92% (23/25) with overall complete resection rate of 72% (18125). Two patients had exploratory laparotomy (thorn- cotomy) only. Thirteen patients had esophagogastrostomy with a combined abdominl and Rt. thoracic approach (Ivor Lewis operation), slx pAtients had transhiatal esophagectomy, four patients had esophagogastrostomy with a combined Rt. thoracotonly & abdominal, cervical approach. There were three postoperative deaths (12%). Follow-up duration was between 3.3 months to 65 months. Median survival ime of resected patients except hospital death was 14.8 months. Actuarial survival at 12, 24 months was 72.9%, 26.2%. Signifi- cant better survival was associated with responder group (postoperative stage less than lIB) (P=0.029). These results demonstrate that 1) Preoperative Cisplatin based combined chemotherapy Produce high response rate, 2) High complete resection rate with acceptable mortality rate occur after preoperative chemotherapy, 3) Better surviL dl can be anticipated if complete resection performed after major re- sponse to preoperative chemotherapy.

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is a maternally inherited mitochondrial disorder of which m.3243A>G is the most commonly associated mutation, resulting in an inability to meet the energy requirements of various organs. MELAS poses a diagnostic challenge owing to its multiple organ involvement and great clinical variability due to its heteroplasmic nature. We report three cases from a family who were initially misdiagnosed with myasthenia gravis or undiagnosed. Although there is no optimal consensus treatment approach for patients with MELAS because of the disease's heterogeneity, our 21-year-long therapy regimen of ${\text\tiny{L}}-arginine$, ${\text\tiny{L}}-carnitine$, and coenzyme Q10 supplementation combined with dietary management appeared to provide noticeable protection from the symptoms and complications. Prompt early diagnosis is important, as optimal multidisciplinary management and early intervention may improve outcomes.

Termitomyces sp. that grow in symbiosis with fungus-farming Termites have medicinal properties. However, they are rare in nature, and their artificial culture is challenging. The expression of AXL receptor tyrosine kinase and immune checkpoint molecules favor the growth of cancer cells. The study evaluated the optimal conditions for the artificial culture of Termitomyces and their inhibitory activity on AXL and immune checkpoint molecules in lung adenocarcinoma and melanoma cell lines. The culture of 45 strains of Termitomyces was compared. Five strains with marked growth rates were selected. Four of the selected strains form a single cluster by sequence analysis. The mycelium of 4 selected strains produces more fungal mass in potato dextrose broth than in a mixed media. The bark was the most appropriate solid substrate for Termitomyces mycelia culture. The mycelium of all five selected strains showed a higher growth rate under normal CO₂ conditions. The culture broth, methanol, and ethyl acetate of one selected strain (T-120) inhibited the mRNA relative expression of AXL receptor tyrosine kinase and immune checkpoint molecules in cancer cell lines. Overall, these results suggest the potential usefulness of Termitomyces extracts as a coadjuvant therapy in malignant diseases.

Patients with acute pyleonephritis may present with a spectrum of clinical symptoms and signs. There are few noninvasive diagnostic studies, however, to confirm or exclude this diagnosis. To evaluate the clinical utility of $^{99m}Tc-DMSA$ renal scan in diagnosis of acute pyelonephritis, we performed $^{99m}Tc-DMSA$ renal scan in 37 patients suspected with urinary tract infection. Simultaneously, kidney ultrasonography was done in 21 patients diagnosed with acute pyelonephritis, clinically. And we performed the followup scan after treatment in two to six weeks. The results were as follows: 1) $^{99m}Tc-DMSA$ renal scan disclosed single or multiple cortical defects and decreased radiouptake ratio of affected kidney in 23 patients among 25 patients diagnosed with acute pyleonephritis. 2) In the 21 patients with acute pyelonephritis, kidney ultrasonography showed abnormal finding in the 7 patients. And $^{99m}Tc-DMSA$ renal scan disclosed abnormal cortical defects in this 7 patients also. 3) Between the patients with acute pyelonephritis and those with lower urinary tract infection, asymptomatic bacteriuria or pyuria. right-to-left radiouptake ratios (R/L ratio) were significantly different (p < 0.001). 4) In two to six weeks after antibiotic therapy, we performed followup $^{99m}Tc-DMSA$ renal scan for 5 patients among 25 acute pyelonephritis patients. And we have found the improvement of cortical defects and the right-to-left radiouptake ratio. In conclusion, we thought that $^{99m}Tc-DMSA$ renal scan should be useful in diagnosis of acute pyelonephritis and follow-up examination.

The purpose of this study was to investigate the effect of the high voltage pulsed Current (HVPC) stimulation on the healing rate and the proliferative activity of keratinocytes and IGF-I mRNA expression of an incisional wound in rat skin. Twenty male Sprague-Dawley rats ($265{\sim}290g$) were randomly divided into HVPC (n=10) and control group (n=10). Rats received 10 mm length of full-thickness incision wound on the back under the anesthesia. The HVPC group received electrical stimulation with a Current intensity of 50 V at 100 pps for a duration of 30 minutes, while the control group was given the same treatment without electricity for a week. Polarity was negative in first three days and positive thereafter. The wound length was measured and evaluated as percentage. The mean number of nucleolar organizer regions (NORs) per nucleus and level of IGF-I mRNA expression were calculated. The mean percent of wound closure were $51.17{\pm}17.76%$ and $80.71{\pm}11.91%$, respectively, in the sham treated control and HVPC stimulated groups (t=-4.308, P<0.001). The mean NOR number per nucleus of the keratinocytes in the control and HVPC group were $1.85{\pm}0.20$ and $2.70{\pm}0.23$, respectively (t=8.638, P<0.001). The IGF-I mRNA level were $0.76{\pm}0.44$ and $1.32{\pm}0.41$, respectively, in the control and HVPC stimulated wounds (t=2.906, P<0.01). There was a positive correlation between the mean NOR number per nucleus and IGF-l mRNA level with a Pearson product moment correlation coefficient of 0.72 (P<0.05). These findings suggest that the HVPC may activate the rRNA of the basal keratinocytes and upregulate the IGF-I mRNA levels by alteration of the electrical environment, and it may increase proliferative activity of the keratinocytes in the skin wound of the rat.
