Large vessel vasculitis is characterized by chronic inflammation within the aortic wall and its major branches. The inflammation is considered to occur as a result of immune dysregulation. Hematologic malignancy is one of the rare causes of secondary vasculitis. Herein, we report a rare case of large vessel vasculitis associated with acute myeloid leukemia mimicking primary vasculitis.

This study investigated sex determination through serum steroid hormone level and compared hematological characteristics of one-year old cultured eels, Anguilla japonica. Four different groups were divided with total length at 40∼45, 45∼50, 50∼55, and 55∼60 cm. Males dominated eels of 40∼50 cm in total length group, while females dominated eels of more than 50 cm. All females and males were immature. Hematocrit levels of males (total length: 40∼50 cm) were higher than those of females (total length: 50∼60 cm). Hemoglobin content also differed between males and females. Glutamate oxaloacetate transaminase (GOT) levels of 40∼45 cm males tended to be higher (157$\pm$3.46 IU/L) than that of other sized males, but there were no significant differences between groups (P<0.05). The highest GOT levels were found in of 55∼60 cm females (148$\pm$3.46 IU/L) compared with that of other female groups (P<0.05). Glutamate pyruvate transaminase (GPT) levels of males and females in the 55∼60 cm size range was significantly higher thanothers (P<0.05). The result of this study indicated steroid hormone content of males and females were very low, but testosterone (T) and estradiol-17$\beta$, (E2) contents of females were higher than those of males. For further research of sex determination in cultured eels, it needs to investigate in more defined body length.

The acute oral, intraperitoneal and subacute toxicity of monocrotophos, an insecticide, was studied in albino rats. The acute oral $LD_{50}$ values for female and male rats were 5.0mg/kg and 8.7mg/kg, respectively. Conversely the intraperitoneal $LD_{50}$ values for female and male rats were 4.9mg/kg and 6.0mg/kg, respectively. Plasma cholinesterase (ChE) activity in rats treated with a single dose was the most depressed 4 hours after administration, but returned to normal within 72 hours of administration. Significant depression of body weight gain and food consumption was observed in rats receiving the 3.5mg/kg/day dose level for 28 days as compared with the controls. Additionally plasma ChE activity depression was also observed.

Objectives : We study the feasibility and pharmacokinetics of cisplatin concurrent chemoradiation for advanced head and neck cancer patient undergoing hemodialysis. Materials and Methods : A 57-year old male with end stage renal disease developed stage III external auditory canal cancer. Complete resection surgery was done. Postoperative 6 months, local recurrence was occurred. Despite excision and adjuvant radiotherapy, local tumor was recurred. We decided to treat a cisplatin concurrent chemoradiotherapy. Cisplatin was administered at a dose of $20mg/m^2$ for 30 min. Hemodialysis was started 30 min after completion of the cisplatin infusion and performed for 4 hours. Hemodialysis was performed on day 3 and 5 of chemotherapy. Plasma samples were collected at specified times after administration of cisplatin. Result : At the end of the third cycle of cisplatin concurrent chemoradiotherapy, the tumor size was markedly decreased. The maximum plasma concentrations of plasma platinum and free platinum were 0.74 and $0.37{\mu}g/ml$ respectively. The area under the curve of plasma platinum and free platinum were 94.7 and $11.3{\mu}g{\cdot}h/ml$ respectively. Conclusion : We report a case of Cisplatin concurrent chemoradiation for hemodialysis patient with advanced head and neck cancer and suggest full dose cisplatin concurrent chemoradiotherpay is tolerable for these patients.

Purpose: Despite the advance of medical science, the number of cancer patient have increased and the mortality rate is also on the rise. Therefore, a perfect cure for cancer is crucial, but the value and meaning of the remaining life for the patient are also becoming more and more important. The principal aim of this study is to examine the differences in the quality of life, physical and psychosocial symptoms according to the performance status of terminal cancer patients. Methods: We evaluated the performance status, demographical data, blood analysis and quality of life of cancer patients who visited the Department of family Medicine at Myoung-ji Hospital in Korea between September 1, 2003 and August 31, 2005. Their performance status (ECOG) was divided into two groups ($ECOG\;0{\sim}1/ECOG\;2{\sim}4$) and analyzed by ANOVA to see if there was a difference in their blood analysis and quality of life. A P value of less than 0.05 was considered to be significant. Results: A total of 104 patients were evaluated, among which 71 patients (23 male and 48 female) scored $0{\sim}1$, and 33 patients (8 males and 25 females) scored $2{\sim}4$ in the ECOG. The blood analysis showed that patients whose performance status was $2{\sim}4$ had lower levels of lymphocytes, hemoglobin, protein, albumin and sodium. The evaluation on their quality of life showed that the overall health status of patients with $2{\sim}3$ functional ability were poor (P=0.02). Also, from a functional perspective, these patients had poor physical (P=0.05) and role (P=0.01) scores, and in terms of symptoms, they showed a significant loss of appetite. Conclusion: If a patient's performance status was poor, levels related to certain nutritions were also found to fall in blood tests, thereby leading to an overall weakened state of health. However, there was no difference in symptoms except for a loss of appetite. In conclusion, it is most important to increase the appetite in patients with poor performance status.

Tumor hypoxia caused by the unique characteristics of solid tumor sites such as lowered vascular density, irregular vasculature, longitudinal oxygen gradient, and unbalanced oxygen consumption has decreased therapeutic efficacy in several clinical trials such as radiation, chemotherapy, and surgery. Hence, tumor oxygenation studies at microvascular levels are important to provide better understanding of the complexity of microvasculature oxygen transport and exchange with tissue. However, polarographic microelectodes, was employed to measure $pO_2$ at the microvasculature level, but it is difficult to perform and does not provide significant spatial and temporal information of oxygen delivery. In this research, we introduce the hyperspectral imaging system able to provide a wide range of vascular characteristics by spatial maps on hemoglobin saturation information for better understanding of the relationship between blood oxygen delivery, hypervascularity, aberrant angiogenesis at microvasculature levels during tumor growth.

Opioid aberrant behavior is an emerging problem as strong opioid is increasingly used to alleviate cancer pain in patients with cancer. Although the treatment of opioid addiction and physical dependence for non-cancer pain is well known, few studies have been conducted with cancer patients, particularly in the Korean population. Presented here are ten cases of cancer patients who were physically dependent on strong opioid and successfully treated with a partial mu-opioid receptor agonist, buprenorphine. This is the first report showing the efficacy of transdermal buprenorphine as a treatment for physical dependence on opioid medication in cancer patients.

마늘과 감초. 둘 다 약성이 뛰어난 식품이다. 마늘은 항암 식품의 대표격으로, 중국에서 최근 실시된 역학조사 결과에 따르면 연간 1.5㎏씩 마늘을 먹는 사람이 암에 걸릴 위험은 거의 안 먹는 사람에 비해 50%나 낮았다. 정자의 수를 늘리고 발기를 돕는다는 동물 실험 결과도 있다. 혈액순환을 돕고 혈압을 내려주는 효과도 있다. 감초는 '약방에 감초' 라는 말이 있을 정도로 한약재에 두루 쓰이는 약초다. 한방에선 대개 여러 약 성분을 조화시키고약의독성을완화시키기위해사용한다.

To elucidate the effect of phytoestrogens on the prevention of neurodegenerative disease in postmenopausal women, the expression of occludin which build up the blood-brain barrier was examined in hippocampus following oral administration of estrogen (E2), genistein, diadzein or combination of genistein and diadzein in ovariectomized (OVX) female rats. E2 significantly increased occludin mRNA level in OVX rat hippocampus, suggesting that estrogen is a physiological regulator for structural integrity of the blood-brain barrier in hippocampus. Following isoflavone diet for 4 weeks, there was significant increase in occludin mRNA level in hippocampus, suggesting that isoflavone diet may be effective for protection of structural integrity of blood-brain barrier in hippocampus from degenerative changes in estrogen deficiency.

Proteome patterns reflect the underlying pathological state of a human organ. It is believed that the anomalies or diseases of human organs are identified by the analysis of the pattern. There are many ways to analysis these patterns. <중략> (colon cancer and leukemia dataset) indicates that the proposed method shows better classification performance and more stable results than other single kernel functions.
