The study has been carried out to investigate of the senile dementia by referring to 35 literratures. The results were as follows ; 1. In oriental medical science, senile dementia is belong to the category of dullness(매病), insanity(癲狂證), weak(虛勞), amnesia(健忘), etc. 2. The cause of senile dementia summarize the phlegm preventid-heart hole(痰迷心竅), marrow lack(髓海不足), aged follow weaking of body and disfunction of the internal organs(年老體弱과 臟腑機能 失調), the bad blood with vatal block(氣滯血瘀), feeling inharmony, etc in the view of oriental medical science and make the vanishment of the cerebral atrophy and the cerebral cell but havn't indicated the remarkable cause in that of western medical science. The diseases with cause make a point of Alzheimer's dementia, frequent infarction dementia, etc and psychological and environmental factor too. The marrow lack is related to Alzheimer's dementia, the feeling inharmony, psychologic and environmental factor, the phlegm prevented-heart hole and bad blood with vatal block, frequent infarction dementia. 3. The senile dementia is related cleary to the function of the internal organs in oriental medical sciences respect Especially in relation to kidney and marrow, it is presented new cause view to solve the cure problem of western medical science is studying its cause only the anatomic pathology with cerebrum and is thinking to solve cure possibility. 4. The symptom of senile dementia is as follows. The obstacle of a aspect of the Language, Emotion, Behavior. mute, speech inversion, sometimes a laugh sometimes a cry, behavior strange, failure of memory etc. 5. The treatment of senile dementia is follows. The methodes of cure apply phlegm changed-mud(豁痰化濁), self-kidney and added marrow(補腎益髓), self-energy and nutritive blood(益氣補血), vital blood(祛瘀活血), peace of mind and relief(安神情志). The medicines of cure make the most of (sesimtang, jwagui-hwan, tonggwuhwalhuel tang) add and subtract, daeboweonjeon, guibitang, and so on.

Recently, many lead-free piezoelectric materials have been investigated for the replacement of existing Pb-based piezoelectric ceramics because of globally increasing environmental interest. There has been remarkable improvement in piezoelectric properties of some lead-free ceramics such as $(Bi,Na)TiO_3-(Bi,K)TiO_3-BaTiO_3$, $(Na,K)NbO_3-LiSbO_3$, and so on. However, no one still has comparable piezoelectric properties to lead-based materials. Therefore, new lead-free piezoelectric ceramics are required. $BiFeO_3$ has a rhombohedrally distorted perovskite structure at room temperature and a very high Curie temperature ($T_C$= 1,100 K). And a very large electric polarization of 50 ~ 60 ${\mu}C/cm^2$ has been reported both in epitaxial thin film and single crystal $BiFeO_3$. Therefore, a high piezoelectric effect is expected also in a $BiFeO_3$ ceramics. The recent research activities on $BiFeO_3$ or $BiFeO_3$-based solid solutions are reviewed in this article.

N/A Objectives: The management of hepatocellular carcinoma(HCC) has been frequently complicated due to the variable hepatic dysfunction from underlying chronic liver disease. The validity of UICC staging system based on the anatomical extent of malignant lesion has been questioned because of the poor correlation between stages and clinical outcomes. The purpose of this study is to elucidate the validity of UICC staging system as a prognostic factor and to compare with Child`s classification which represents the functional status of liver. Methods: A total of 831 patients with HCC who received no specific anti-cancer treatment, TACE and/or systemic chemotherapy, between January 1988 and December 1991, were analyzed retrospectively. Factors influencing the prognosis were analyzed by Cox proportional-hazard regression model. Results: Median survival of overall HCC patients was 4 months. There was no significant difference in overall median survival between UICC stage III and IVA; but significant differences between Child A and B, Child B and C were found. UICC staging system for HCC gave less significant clinical value in predicting the survival of HCC patients regardless of the treatment modalities given. In contrast, Child`s classification was better correlated with the survival of HCC patients who received systemic chemotherapy and no specific treatment. In Cox proportional-hazard regression model, Child`s classification was the most influential prognostic factor exceeding the role of UICC system.. Conclusion: UlCC staging system is not a good system for the staging of HCC. We beIieve that the poor correlation between stages and survival originated from the neglect of hepatic dysfunction which is the major prognostic factor in HCC. It is necessary to develop a new staging system which can represent the prognosis better.

N/A Esophageal cancer is widely disseminated in more than 80% of patients at the time of diagnosis and the prognosis of advanced esophageal cancer is dismal with a median survival of 5 to 8 months. Therefore, systemic chemotherapy has assumed an important role in the treatment of these patients. Among various combination chemotherapy regimens, the combination of cisplatin and 5-fluorouracil has been one of the most effective for esophageal cancer because of their synergism. Etoposide, although reported ineffective as a single agent, has been shown to be synergistic with cisplatin in vitro and in vivo. So, we conducted a phase 2 trial to evaluate the effect of a combination of cisplatin, etoposide and 5- FU (PEF) in patients with metastatic or recurrent esophageal cancer. Thirty-four patients with measurable lesion(s) received cisplatin (20㎎/㎡ i.v. Day 1~5), etoposide (100㎎/㎡ i.v. Day 1, 3 & 5) and 5-FU (800㎎/㎡ continuous i.v. for 12 hours, Day 1~5). Of 30 evaluable patients, 1(3.3%) had a complete response and 11(37%) had partial responses. The median duration of response was 29 weeks. The overall median survival was 34 weeks and the survival time in the responders was longer significantly than that of the non-responders. There was no significant prognostic factor influencing the response rate. Among total 135 cycles of chemotherapy, leukopenia was observed in 36% and thrombocytopenia in 4%. There was no treatment-related death. Main non-hematologic toxicities were neurotoxicity (17%), nephrotoxicity (3%), and stomatitis (10%) and diarrhea (10%). All the toxicities were mild and well tolerated. Conclusion: A combination chemotherapy of cisplatin, etoposide and 5-FU (PEF) was effective and well tolerated in patients with metastatic or recurrent esophageal cancer.

N/A The prognosis of esophageal cancer is very poor. Even for those with localized disease who are potentially curable, 5-year survival rates are under 20% in almost all series. We conducted a pilot study to evaluate the safety and possibility of efficacy of neoadjuvant chemotherapy followed by surgery in patients with locally advanced esophageal cancer. Two or three cycles of neoadjuvant combination chemotherapy with cisplatin (20㎎/㎡/day i.v., D1-5), etoposide (100㎎/㎡/day i.v., D1,3,5), and 5-fluorouracil (800㎎/㎡/day continuous i.v., D1-5) were planned to be given before surgery. Total 21 patients entered this trial. Three patients were lost to follow-up after 1 cycle of chemotherapy to make eighteen patients evaluable. Thirteen out of eighteen patients (72%) had objective improvement after neoadjuvant chemotherapy and four (22%) had no change and one (6%) had progression. Among 18 evaluable patients, surgery was performed in 11 patients. Surgery could not be done in 7 patients because of patient's refusal (5), progression of disease (1), and development of lung abscess (1). In 13 patients who were candidates for surgery, curative resection was done in 10 patients to make curative resection rate 10/13 (77%). One of eleven patients having surgical resection had no pathologic evidence of tumor (pathologic complete remission 9%). Postoperative complications of wound dehiscence and anastomotic site fistula developed in 2 patients. Three courses of postoperative adjuvant chemotherapy with PEF regimen were administered to 9 patients. The median survival time for all 18 patients was 60 weeks. Toxicities of PEF neoadjuvant chemotherapy were leukopenia, nausea/vomiting and alopecia, but they were mild and reversible. There was no treatment-related deaths. In conclusion, neoadjuvant chemotherapy with PEF regimen were tolerable, safe and possibly effective in locally advanced esophageal cancer. Based on this study, we will perform phase 2 or 3 study to assess the efficacy of PEF neoadjuvant chemotherapy for locally advanced esophageal cancer.
