Objectives: To investigate the effect of glycopeptide-preferring polypeptide GalNAc transferase 1 (ppGalNAc T1 ) targeted RNA interference (RNAi) on the growth and migration of human bladder carcinoma EJ cells in vitro and in vivo. Methods: DNA microarray assays were performed to determine ppGalNAc Ts(ppGalNAc T1-9) expression in human bladder cancer and normal bladder tissues. We transfected the EJ bladder cancer cell line with well-designed ppGalNAc T1 siRNA. Boyden chamber and Wound healing assays were used to investigate changes of shppGalNAc T1-EJ cell migration. Proliferation of shppGalNAc T1-EJ cells in vitro was assessed using [3H]-thymidine incorporation assay and soft agar colony formation assays. Subcutaneous bladder tumors in BALB/c nude mice were induced by inoculation of shppGalNAc T1-EJ cells and after inoculation diameters of tumors were measured every 5 days to determine gross tumor volumes. Results: ppGalNAc T1 mRNA in bladder cancer tissues was 11.2-fold higher than in normal bladder tissues. When ppGalNAc T1 expression in EJ cells was knocked down through transfection by pSUPER-shppGalNAc T1 vector, markedly reduced incorporation of [3H]-thymidine into DNA of EJ cells was observed at all time points compared with the empty vector transfected control cells. However, ppGalNAc T1 knockdown did not significantly inhibited cell migration (only 12.3%). Silenced ppGalNAc T1 expression significantly inhibited subcutaneous tumor growth compared with the control groups injected with empty vector transfected control cells. At the end of observation course (40 days), the inhibitory rate of cancerous growth for ppGalNAc T1 knockdown was 52.5%. Conclusion: ppGalNAc T1 might be a potential novel marker for human bladder cancer. Although ppGalNAc T1 knockdown caused no remarkable change in cell migration, silenced expression significantly inhibited proliferation and tumor growth of the bladder cancer EJ cell line.

개불 당단백질의 sarcom 180 cell 고형암 성장 저지능은 4mg/kg에서 43.63%로 나타났으나, 20mg/kg이상의 농도에서는 고형암 성장 저지능을 보이지 않았다. Sarcom 180 cell에 대한 수명 연장 실험에서도 2mg/kg와 4mg/kg의 저농도에서는 상당한 수명연장 효과를 보였으나, 2Omg/kg 이상의 고농도 투여군에서는 수명연장 효과를 나타내지 않았다. 개불 당단백질의 sarcoma 180 cell에 대한 직접적인 세포 독성 효과는 농도의 증가에 따라 약간의 종양세포 살해효과를 보였으나, 그 효과는 미약하였다. 개불 당단백질의 면역능 증진효과는 체중에 대한 간과 비장의 중량비 증가, 총 복강세포수의 증가 그리고, 당단백질을 고농도 투여시 30.78%~46.30%정도의 백혈구 수 증가 등으로 확인되었다. 이러한 결과로서 개불에서 추출한 당단백질의 항암효과는 면역활성의 증진과 면역자극의 효과라고 볼 수 있었으나, 전반적인 면역활성의 증가에도 불구하고, sarcoma 180 cell에 대한 고형암 성장 저지실험과 수명연장실험에서 고농도로 투여시에는 오히려 활성이 나타나지 않았다. 따라서 개불 당단백질의 최적투여 농도와 고농도 투여시의 부작용에 관한 더 많은 연구가 필요하였다. 이상의 결과에서 개불에서 추출한 당단백질의 면역자극에 의한 항종양 활성을 확인 되므로, 일반적으로 사용되어지는 항암 화학요법제와 더 불어 병행될 수 있는 면역증진제로서의 개발 가능성이 있다고 보여진다.

The Artemisia capillaris THUNB is a perennial herb that belongs to the family Compositae spp and probably the most common plant among the various herbal folk remedies being used in the treatment of abdominal pain hepatitis chronic liver disease, jaundice and coughing in Korea. Recently the biological and pharmacological actions of herb have been studied well such as antibacterial, antidiabetic and antitumor activities. This experiment was conducted to investigate antitumor and immunomodulatory effects of Artemisia capillarix extracts against Hepa-1c1c7 and Sarcoma 180 cancer cells on in vivo experimental tests. On in vivo experimental tests using 280 ICR mice the gain of body weight in the control-group mice bearing Sarcoma 180 ascites tumor was 1.5 times more than that of the normal-group mice after 33 days. However, the gain of body weight in all experimental groups administered with Artemisia capillaris extracts was significantly lower than that of the control-group mice (P<0.05). The mean survival times of mice administered with Artemisia capillaris extracts of 25 and 100 mg/kg for 28 days were shown to be 25.39% and 15.39% longer than that of the control-group mice injected with saline (P<0.05). Artemisia capillaris extracts showed the highest tumor inhibition effects, which were 42.4% and 27.2% when intraperitoneally injected with doses of 25 and 100 mg/kg once a day for 28 days in inoculated ICR mice with Sarcoma 180 solid tumor cells (P<0.05). The results suggest that Artemisia capillaris methanol extracts have prominent antitumor effects on the cancer cell lines Hepa-1c1c7 and Sarcoma 180.

Purpose: To introduce our early experience with intensity-modulated radiotherapy (IMRT) in the treatment of nasopharyngeal carcinoma. Methods and Materials: Eight patients who underwent IMRT for no disseminated nasopharyngeal carcinoma at the Asan Medical Center between September 2001 and November 2002 were evaluate by prospective analysis. According to the 1997 American Joint Committee on Cancer staging classification, 5 had Stage III, and 3 had Stage IVB disease. The IMRT plans were designed to be delivered as a 'Simultaneous Modulated Accelerated Radiation Therapy' (SMART) using the 'step and shoot' technique with a MLC (multileaf collimator). Daily fractions of 2.2-2.5Gy and 1.9-2Gy were prescribed and delivered to the GTV and CTV and clinically negative neck node, respectively. The prescribed dose was 70A-79.0Gy to the gross tumor volume (GTV), 60Gy to the clinical target volume (CTV) and metastatic nodal station, and 46Gy to the clinically negative neck. All patients also received weekly cisplatin during radiotherapy. Acute and late normal tissue effects were graded according to the Radiation Therapy Oncology Group (RTOG) radiation morbidity scoring criteria. Results: Follow-up period was ranging from 5 to 18 months. All patients showed complete response and loco-regional control rate was 100% but one patient died of malnutrition due to treatment related toxicity. There were no Grade 3 or 4 xerostomia and all patients had experienced improvement of salivary gland function. Conclusion: 'Simultaneous Modulated Accelerated Radiation Therapy' (SMART) boost intensity-modulated radiotherapy technique allows parotid sparing as evidenced both clinically and by dosimetry. Initial tumor response and loco-regional control was promising. It is clinically feasible. A larger population of patients and a long-term follow-up are needed to evaluate ultimate tumor control and late toxicity.

Purpose : This study examined effects of Paljin-tang on endometriosis. Methods : Sugically induced endometriosis in rats were given an oral dose of Paljin-tang for 40 days. The size of the ectopic uterine implants at the serosal wall and the concentration of progesterone, estradiol, tumor necrosis factor(TNF)-${\alpha}$ and interleukin(IL)-2, IL-4, IL-6, and IL-10 in the blood were examined and compared with the control group. Results : The size of the ectopic uterine implants in the experimental group was much smaller than of that in the control group. The concentration of estradiol was significantly lower in the experimental group than in the control group. The TNF-${\alpha}$, IL-4, IL-6 levels was significantly lower in the experimental group than the control group and IL-10 level was higher in the experimental group than the control group. The progesterone, IL-2 levels were similar in the experimental and control groups. Conclusion : These results indicate that Paljin-tang reduces the size of ectopic uterine implants at the serosal wall and inhibits the growth of ectopic uterine implants. This suggests that Paljin-tang is an effective treatment for endometriosis.

Objectives: In Fujian Province, China, gastric cancer is one of the leading causes of mortality among all malignant tumors. Nanjing county and Minqing county are located in inland Fujian and have similar general demographics. However, the adjusted mortality rate of gastric cancer in Minqing was found to be much higher than that in Nanjing. We sought to explore factors associated with this increased risk of gastric cancer between the two counties. Methods: We recruited 231 and 224 residents from Nanjing and Minqing, respectively, and analyzed differences between their dietary habits, Helicobacter pylori infection rates, and concentrations of serum pepsinogen I, pepsinogen II, gastrin-17, and ratio of pepsinogen I:II. Results: Subjects in Minqing had more first-degree relatives who had been diagnosed with upper gastrointestinal tumor, more unhealthy dietary habits, a higher Helicobacter pylori positive rate, and greater proportion of abnormal serum gastrin-17 than those in Nanjing did. Conclusions: The factors that differed between these two counties might indicate that residents in Minqing have a higher risk for developing gastric cancer than those in Nanjing do.
