Consumption of herbal tea [flower buds of Cleistocalyx operculatus (Roxb.) Merr. et Perry (Myrtaceae)] is associated with health beneficial effects against multiple diseases including diabetes, asthma, and inflammatory bowel disease. Emerging evidences have reported that High mobility group box 1 (HMGB1) is considered as a key "late" proinflammatory factor by its unique secretion pattern in aforementioned diseases. Dimethyl cardamonin (2',4'-dihydroxy-6'-methoxy-3',5'-dimethylchalcone, DMC) is a major ingredient of C. operculatus flower buds. In this study, the anti-inflammatory effects of DMC and its underlying molecular mechanisms were investigated on lipopolysaccharide (LPS)-induced macrophages. DMC notably suppressed the mRNA expressions of TNF-alpha, IL-1beta, IL-6, and HMGB1, and also markedly decreased their productions in a time- and dose-dependent manner. Intriguingly, DMC could notably reduce LPS-stimulated HMGB1 secretion and its nucleo-cytoplasmic translocation. Furthermore, DMC dose-dependently inhibited the activation of phosphatidylinositol 3-kinase (PI3K), phosphoinositide-dependent kinase 1 (PDK1), and protein kinase C alpha (PKCalpha). All these data demonstrated that DMC had anti-inflammatory effects through reducing both early (TNF-alpha, IL-1beta, and IL-6) and late (HMGB1) cytokines expressions via interfering with the PI3K-PDK1-PKCalpha signaling pathway.

This study was carried out to investigate the intake patterns of health food according to the kind of disease of the elderly aged over 60 years living in the Chuncheon area. This study was conducted by using a questionnaire from December 1999 to the March 2000. The data was analyzed using a SPSS program. The results were summarized as follows : The poorer the self-perceived health condition, the lower the level of activity of daily living(ADL) and instrumental activities of daily living(IADL) were the higher. the frequency score of health food intake. The incidence of disease, such as arthritis(44.7%), hypertension(18.8%), digestive diseases(17.1%), diabetes(10.5%) were found to be higher. than other chronic diseases among the elderly. The frequency score of health food intake was not significantly different according to self-perceived health status, disease status, or the level of ADL and IADl.. The must important source of information for health food intake was the recommendation of friends and relatives(68.7%). Twenty eight point two percent of the elderly considered health foods to be effective, however 8.3% of the elderly considered them to be ineffective. The elderly with chronic diseases had taken health floods in the descending order of neuralgia-arthritis, hypertension, digestive disease, diabetes. The elderly with digestive diseases, diabetes, renal disease, neuralgia-arthritis and respiratory disease were inclined to habitually take health floods once or twice per year. Intake of Korean traditional folk food was as high as intake of registered health food and Chinese tonic medicine. The most frequently taken health food was tonic medicine, which is fo11owed by pumpkin, ginseng products, herbal tea formula with black goat, deer antler and Kye-so-ju. Intakes of health food such as tonic medicine, blood of the deer, royal jelly, aloe were found to be higher among the elderly with chronic diseases such as diabetes, hypertension, and digestive disease. However, intakes of ginseng products, deer antler, pumpkin, herbal tea formula with black goat and Kye-so-ju were found to be higher among the healthy elderly. The elderly with neuralgia-arthritis had taken sixteen kinds of health foods. From these results, a wide consumer education program should be developed to convince people of the importance of well-balanced diet and to choose proper health foods according to the elderly's health conditions. Also, comprehensive and scientific research into Korean traditional folk foods are needed for the correct use.

Hepatic veno-occlusive disease (VOD) is a rare disease due to occlusion of the terminal hepatic venules and/or sublobular veins, which is a result of endothelial damage from pyrrolizidine alkaloids in herbal teas, irradiation of the liver, or chemotherapy particularly in association with bone marrow transplantation. We recently experienced three cases of VOD developed after radiation therapy. Two cases occurred in hepatocellular carcinoma patients of a 37-year-old man with B viral chronic hepatitis and a 22-year-old man with B viral cirrhosis and the other in a 64-year-old patient with esophageal squamous cell carcinoma. For the treatment of hepatocellular carcinoma, chemoembolization with lipiodol and adriamycin, and external irradiation on the liver mass were done. The total radiation dose was 5400 cGy and 3000 cGy in each case. Five months and 3 months after irradiation, respectively, the resected liver masses showed extensive necrosis due to pre-operative treatment. To treat esophageal carcinoma, pre-operative concurrent chemotherapy of 5-FU and radiation of 4500 cGY were done. One month after irradiation, the radical esophgectomy and wedge biopsy of the liver were done. The liver of all 3 cases showed a dark red appearance with severe congestion in contrast to the pale brown normal liver, which was not included in the radiation field. On micoscopic examination, the terminal hepatic venules and sublobular veins showed subintimal edema, fibrin deposition, and partial or total luminal occlusion by loose fibrous tissue. The centrizonal sinusoids were markedly dilatated and congested with atrophy of hepatocytes.
