It is well known that $^{99m}Tc-sulfur$ colloid or phytate hepatic scintigraphy is highly sensitive but not specific. Both $^{99m}Tc-DISIDA$ and bilirubin have been shown to share the same anionic transport pathway in the liver. Hepatocellular carcinoma(HCC) retains the ability to produce bile but has marked limitation to excreting it resulting in accumulation of bile within the tumor cells. Based upon such a fact, $^{99m}Tc-DISIDA$ hepatobiliary scintigraphy is used for the diagnosis of HCC. The present communication deals with our experience of DISIDA scintigraphic exploration of 9 cases of HCC in a retrospective way. We have made an observation on intensity of positive radio nuclide accumulation in the cold area of HCC as it is demonstrated by phytate scintigraphy. In addition we have semi quantitatively analyzed time-activity pattern and the following results were obtained. (1) All of 9 cases showed an increased uptake of $^{99m}Tc-DISIDA$ in delayed scintigrams. Of these 5 cases showed accumulation less than, 3 equal to, 1 more than the surrounding liver tissue. (2) The mean of the first appearing time of $^{99m}Tc-DISIDA$ activity in tumoral region was 2 hours and 20 minutes. (3) DISIDA scintigraphy provides us with positive informations of diagnostic value.

The multicellular layers(MCL) of human cancer cells is a three dimensional(3D) in vitro model for human solid tumors which has been used primarily for the assessment of avascular penetration of anti-cancer drugs. For anti-cancer drugs with penetration problem, MCL represents a good experimental model that can provide clinically relevant data. Calcein-AM is a fluorescent dye that demonstrates the cellular vitality in a graded manner in cancer cell culture system. In the present study, we evaluated the use of calcein-AM for determination of anti-proliferative activity of anti-cancer agents in MCL model of DLD-1 human colorectal cancer cells. Optical sectioning of confocal imaging was compromised with photonic attenuation and penetration barrier in the deep layers of MCL. By contrast, fluorescent measurement on the cryo-sections provided a feasible alternative. Cold pre-incubation did not enhance the calcein-AM distribution to a significant degree in MCL of DLD-1 cells. However, the simultaneous determination of drug penetration and cellular vitality appeared to be possible in drug treated MCL. In conclusion, these data suggest that calcein-AM can be used for the simultaneous determination of drug-induced anti-proliferative effect and drug penetration in MCL model.

Facial nerve paralysis(or Bell's palsy) which commonly occurs unilaterally, gives rise to paralysis of facial expression muscle. This condition is classified into symptomatic facial nerve paralysis due to intracranial tumor, post operative trauma, etc. and idiopathic facial nerve paralysis. To explain the etiology of idiopathic facial nerve paralysis, many hypothesis including ischemic theory, viral infection, exposure to cold, immune theory etc. were suggested, but there is no agreement at this point. The method to evaluate the facial nerve paralysis, when it occurs, consists of three stage scale method, image thechnics like CT and MRI, laboratory test to examine the antibody titers of viral infection, neurophysiologic test to evaluate the degree and prognosis of paralysis. Treatment includes medication, stellate ganglion block(SGB), surgery, physical therapy and other home care therapy. In medication, systemic steroids, vitamins, vasodilating-drug and ATP drugs were used. SGB was also used repeatedly to attempt the improvement of circulation and to stimulate the recovery of nerve function. Physical therapy including electric acupuncture stimulation therapy(EAST) and hot pack was used to prevent the muscle atrophy. When No response was showed to this conservative therapies, surgery was considered. After treating two patients complaining of Bell's palsy with medication(systemic steroids) and EAST, favorable result was obtained. so author report the case of facial nerve paralysis.

When 10 kinds of herbal medicines were fractionated into hexane, MeOH, cold-water, and hot-water extracts, hot-water extracts from Acanthopanax senticosus (AS), Glycyrrhiza uralensis (GU), Cichorium intybus (CI), and Polygonatum odoratum (PO) showed the potent intestinal immune system modulating activity (1.72-, 1.62-, 1.60-, and 1.53-fold of control at $100{\mu}g/mL$, respectively). Especially, hot-water extracts from AS (215% compared with the control) and GU (187%) also had macrophages stimulating activity and mitogenic activity of splenocytes (7.1- and 6.5-fold) at $100{\mu}g/mL$. In addition, the effects of hot-water extracts from herbal medicines on anticancer activities were studied in mice. Hot-water extracts from AS and GU enhanced cytotoxicity of natural killer cell against cancer cell, Yac-1 (37 and 34% cytotoxicity) at E/T ratio 100:1, and colon 26-M3.1 cancer cell lines had significantly inhibited (82.1 and 75.2%) in experimental lung metastasis. These results suggest that hot-water extracts from A. senticosus and G. uralensis can be used as biological response modifiers to stimulate immune system and inhibit tumor.

Pancreatic cancer is a highly aggressive malignant tumor of the digestive system and radical resection, which is available to very few patients, might be the only possibility for cure. Since therapeutic choices are limited at the advanced stage, prevention is more important for reducing incidence in high-risk individuals with family history of pancreatic cancer. Epidemiological studies have shown that a high consumption of fish oil or ${\omega}3-polyunsaturated$ fatty acids reduces the risk of pancreatic cancers. Dietary fish oil supplementation has shown to suppress pancreatic cancer development in animal models. Previous experimental studies revealed that several hallmarks of cancer involved in the pathogenesis of pancreatic cancer, such as the resistance to apoptosis, hyper-proliferation with abnormal $Wnt/{\beta}-catenin$ signaling, expression of pro-angiogenic growth factors, and invasion. Docosahexaenoic acid (DHA) is a ${\omega}3-polyunsaturated$ fatty acid and rich in cold oceanic fish oil. DHA shows anti-cancer activity by inducing oxidative stress and apoptosis, inhibiting $Wnt/{\beta}-catenin$ signaling, and decreasing extracellular matrix degradation and expression of pro-angiogenic factors in pancreatic cancer cells. This review will summarize anti-cancer mechanism of DHA in pancreatic carcinogenesis based on the recent studies.

Background: Thyroid cancer is a relatively rare neoplasm and its incidence varies geographically and ethnically around the world. Thyroid cancer is the most common endocrine malignancy, but it has a wide spectrum of biologic behavior, histologic appearance, and management. Purpose: The purpose of the study was to analyse and evaluate all aspects of the clinical consideration in thyroid cancer. Method: Between 1986 and 1995, a retrospective analysis of 77 thyrod cancer patients admitted at the Department of Surgery, Hangang Sacred Heart Hospital, Hallym University was made to assess clinical entities. Result: By the pathological classification, the papillary carcinoma was the most common type(83.1%). Male to female ratio was 1 : 5.4 and most prevalent age group was noted from fourth decade to fifth decade(46.8%). The most common duration of illness between the appearance of the symptoms and the treatment was below 6 months(44.2%), and the most common symptom was the palpable mass at the anterior portion of the neck(96.1%). Most cases of the thyroid cancer were appeared as cold nodule in the $^{99m}$Tc-thyroid scan(95.7%). In the site of tumor location, the right and left lobe was distributed similarly. In the extent of tumor, incidence of intrathyroidal location was 41.6%, and that of the metastasis to the cervical lymph nodes was 44.2% and that of the direct capsular invasion was 27.3%, and incidence of both involved case was 13%. Surgical procedures were total thyroidectomy alone in 27 cases(35.1%) or with modified neck dissection in 6 cases(7.8%), or with radical neck dissection in 2 cases (2.6%), near total thyroidectomy alone in 22 cases(28.6%), ipsilateral lobectomy with isthmectomy alone in 12 cases(15.6%) or with modified neck dissection in 1 case(1.3%), and biopsy only in 7 cases(9.1%). The most common postoperative complications were transient hypoparathyroidism(5.2%) and transient unilateral recurrent laryngeal nerve paralysis(5.2%). Conclusion: The major problem of management of thyroid cancer include a wide spectrum of clinical behaviour of this tumor entity, the lack of reliable prognostic factors and lack of an objective assessment of the various treatment modalities. But because of showing the favorable prognosis for most thyroid cancer, appropriate and aggressive management should be recommended.

목 적 : 두경부 종양의 방사선치료에서 동일 방사선 조사면을 분리하여 X-선과 전자선을 인접시켜 조사하는 경우는 빈번히 사용되는 방법이다. 따라서 본 연구는 X-선과 전자선 조사면의 인접면에서의 선량을 측정하여 임상에 적용할 수 있는 자료를 얻고자 하였다. 대상 및 방법 : 본 연구는 Clinac1800 (Varian, USA) 선형가속기에서 방출되는 6MV X-선과 9 MeV 전자선을 이용하였다. 흡수선량을 측정하기 위해 X-OMAT V film을 사용하였다. 조사야 $10cm{\times}10cm$에 0.1Gy - 4Gy를 조사하여 film densitometer (WP102 : Welhofer, German)로 OD 값(광학 밀도)를 얻어 film의 특성 곡선을 얻었다. X-선과 전자선 조사면을 분리하여 인접 조사할 때 X-선 조사면은 $10cm{\times}10cm$의 X축 중심에서 2 cm부터 폭 3cm의 차폐를 하고 X-선 조사면에서 차폐된 부분을 전자선 조사면으로 하였다. 전자선 조사면은 $15cm{\times}15cm$ cone을 이용하였다. 흡수선량 측정은 solid water phantom에서 깊이 0 cm(표면), 0.5 cm, 1.5 cm, 2cm, 3 cm에서 film을 설치하고 X-선은 8 cm 깊이에 100 cGy를 조사하고 전자선은 SSD(source surface distance) 100cm로 표면에서 X-선 조사면에 일치시키고 1Gy를 조사하였다. 선량 측정은 X-선과 전자선 조사면의 인접면에서 film densitometer로 scan하여 OD 값을 구하고 6 MV X-선의 Dmax의 OD값을 기준으로 비교하였다. 기준 흡수선량을 구하기 위해 X-선과 전자선 각각의 흡수선량을 깊이 0 cm(표면), 0.5cm, 1.5cm, 2cm, 3cm에서 측정하였다. 결 과 : X-선과 전자선의 조사면을 인접시켰을 때 깊이 0 cm, 0.5 cm, 1.5 cm, 2 cm, 3 cm에서의 두 조사면의 인접면에서의 선량 분포의 분석에서 X-선 조사면에서 선량 증가는 깊이 1.5 cm에서 폭 7 mm에 걸쳐 있었고 최고 $6\%$의 증가를 보였으며 다른 측정 깊이에서는 선량증가가 허용범위 내에 있었다. 그리고 전자선 조사면쪽에서 선량 감소는 전 측정 깊이 0.5 cm-3 cm에서 각각 폭이 1mm-12.5 mm에 걸쳐 $4.5\%-30\%$의 주변부보다 선량감소를 보였다. 결 론 : 본 연구에서 X-선과 전자선을 표면에서 인접시켜 조사 할 때 두 조사면의 인접면을 중심으로 X-선 조사면 쪽에서 선량증가, 전자선 조사면쪽에서 선량 감소가 있음을 확인하였다. 위의 연구 결과는 X-선과 전자선의 인접 방사선조사를 할 때 유용한 참고 자료가 될 수 있겠다.
