Objective: The role of chemotherapy in locally advanced head and neck cancer has been established in nasopharynx and larynx as definitive therapy and organ preserving therapy, respectively. Oral cavity cancers are relatively uncommon and local recurrence is the main cause of treatment failure. We planned this retrospective study to evaluate the role of neoadjuvant chemotherapy in locally advanced oral cavity cancer patients. Materials and Methods: From 1988 March to 2001 February, locally advanced, previously untreated oral cavity cancer patients who received neoadjuvant chemotherapy were examined. Chemotherapy had been done in the following patients: Histologically proven squamous cell or poorly differentiated carcinoma, stage 3 or 4, and performance state 0-2 patients. Chemotherapy regimen consisted of cisplatin and infusional 5-fluorouracil. Response was evaluated after 2 cycles and in case of no response, definitive local therapy was done; otherwise 3 cycles was done before local treatment. Results: 48 patients were treated and 47 patients were evaluable for responses. Complete response rate was 6.4%(3/47) and partial response 80.0%(38/47), scoring overall response rate of 87.2%. Median time to progression was 27.0 months (95% CI : 0-58months) and overall 5 year survival was 54.8%. 5-year disease-free survival in the patients in remission after local treatment was 51.9%. In multivariate analysis, contributing factor to the survival were response to neoadjuvant chemotherapy and local treatment modalities. Extensive surgery was done in 10 patients and 25 patents (52.1%) was followed up with preserved function. With median follow-up of 57.0 months, 19 recurrences were detected, most of which were local or regional type. Conclusion: Neoadjuvant chemotherapy followed by local treatment in oral cavity cancer showed high response rate and was thought to be effective therapeutic approach especially in view of organ preservation.

Objectives: The aim of this study was to estimate the single oral toxicity of Peucedani Radix (PR) ethanol extracts. PR is one of the important herbs for removal of phlegm, the viscous turbid pathological product that can accumulate in the body and cause a variety of diseases. However, research on the pharmacologic toxicity of PR is lacking. Methods: In this study, PR was orally administered to 5-week-old male ICR mice at an oral dose of 2,000, 3,000, or 5,000 mg/kg. After a single-dose administration, the mortality and behavioral changes were observed daily and body weights were measured every two days. After 14 days, the organ weight, organ index, macroscopy, hematological analysis, and serum biochemistry analysis were determined. Results: No mortality, body weight changes, abnormal behavioral changes, or anatomical signs of toxicity were found. The organ weight, organ index, hematological analysis, and serum biochemistry analysis were also within the normal ranges. Conclusions: These results suggest that the 50% lethal dose of PR is more than 5,000 mg/kg. This could indicate that PR is a safe drug without acute toxicity and side effects.

The cough is generally known as a symptom occurred from Lung. But it was descriptive of the symptom every internal organs can cause in "HwangjenaegyeongSomun Haelon". The reason is that, when a pathogenic Gi attack human body, the body skin which have the relationship to Lung is attacked firstly. But the internal organs preside over each seasons of the year, so the season's presiding organ is ultimately attacked. And in "Somun Haelon" the partner symptoms of five solid organs cough and six hollow organs cough are being described, so we can distinguish between each internal organs coughs. Clinically, the cough is most common symptom and one of the most difficult symptom. In my opinion, the origin organ of cough is very various, but the doctor fix their thinking to the Lung, so the cough became a most difficult symptom. This thesis describe pathogenesis and partner symptoms of five solid organs cough and six hollow organs cough. And illustrate clinical examples and some medical prescriptions. Intend to show that various treatment after differentiation of syndromes[辨證施治] surely needed for effective curing of a cough.

Exponential growth has been observed in nuclear medicine procedures worldwide in the past decades. The considerable increase is attributed to the advance of positron emission tomography and single photon emission computed tomography, as well as the introduction of new radiopharmaceuticals. Although nuclear medicine procedures provide undisputable diagnostic and therapeutic benefits to patients, the substantial increase in radiation exposure to nuclear medicine patients raises concerns about potential adverse health effects and calls for the urgent need to monitor exposure levels. In the current article, model-based internal dosimetry methods were reviewed, focusing on Medical Internal Radiation Dose (MIRD) formalism, biokinetic data, human anatomy models (stylized, voxel, and hybrid computational human phantoms), and energy spectrum data of radionuclides. Key results from many articles on nuclear medicine dosimetry and comparisons of dosimetry quantities based on different types of human anatomy models were summarized. Key characteristics of seven model-based dose calculation tools were tabulated and discussed, including dose quantities, computational human phantoms used for dose calculations, decay data for radionuclides, biokinetic data, and user interface. Lastly, future research needs in nuclear medicine dosimetry were discussed. Model-based internal dosimetry methods were reviewed focusing on MIRD formalism, biokinetic data, human anatomy models, and energy spectrum data of radionuclides. Future research should focus on updating biokinetic data, revising energy transfer quantities for alimentary and gastrointestinal tracts, accounting for body size in nuclear medicine dosimetry, and recalculating dose coefficients based on the latest biokinetic and energy transfer data.

Objectives : Hyangsayangyi-tang (香砂養胃湯) is a polyherbal formula, has been used as one of the representative So-eumin (少陰人) prescriptions in Sasang-medicine (四象醫學), a famous Korean medicinal theory. The aqueous extract of Hyangsayangyi-tang (HSYYT) was evaluated for its possible ameliorative effect in the regulation of hypothyroidism related reproductive organ damages in propylthiouracil (PTU)-induced rat model. Methods : HSYYT aqueous extracts were administered, once day for 42 days from 2 weeks before start of PTU treatment as an oral dose of 500, 250 and 125 mg/kg (bodyweight), and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28days. Results : PTU induced hypothyroidism and related male reproductive organ (testis, epididymis and prostate) damages were favorably and dose-dependently inhibited by treatment of HSYYT 500 and 250 mg/kg, and they also effectively regulated the PTU-induced abnormal antioxidant defense system changes in the testis. No effective or any harmful changes on the PTU induced hypothyroidism and related male reproductive organ damages were observed in HSYYT 125 mg/kg treated rats as compared with PTU control in this experiment. Conclusions : The results obtained in this study suggest that oral administration of 500 and 250 mg/kg of HSYYT showed favorable effects on the hypothyroidism and related reproductive organ damages through augmentation of antioxidant defense system in the testis, and it is considered that HSYYT may be help to ameliorate the hypothyroidism and related organ damages in clinics.

The aim of this study was to understand the function & the character of meridians through the theory of Gae-Hap-Chu (開闔樞). Methods : First, We researched the meaning of Gae-Hap-Chu from Internal Classic (內經). Then, We investigated the theory of Gae-Hap-Chu (開闔樞) comparing with the principle of Oriental studies. The last, we considered the function & the character of Gae-Hap-Chu (開闔樞). Results & Conclusions : Gae-Hap-Chu represents distributing-gathering-controlling of meridians and suggests the place of meridians acting. Gae-Hap-Chu is true to the principle of Sam-Jae (三才原理) and interrelationship of Jang-Bu organ (臟腑相關) is also true to the study of Sang-Su (象數學). Descending & ascending meridians make a interrelationship of Jang-Bu organ individually. The function of gathering & distributing is expanded on Yang meridians. Heart & Gallbladder Meridians control Hap (闔) and Kidney& Triple Energizer meridians control Gae (開).
