Identification and HPLC Quantification of a Phytoecdysone and Three Phenolic Glycosides in Lamium takesimense Nakai

The herbs of Lamium takesimense Nakai (Lamiaceae) is used to treat spasmodic and inflammatory disease. The four polar compounds, ecdysterone, isoacteoside, rutin and lamiuside C, were isolated and identified from the BuOH fraction of the L. takesimense MeOH extract. HPLC quantification was performed on a Capcell Pak C18 column (5 µm, 4.6 mm × 250 mm) with a gradient elution of H₂O and 0.05% acetic acid in MeOH. The HPLC method was validated in terms of linearity, sensitivity, stability, precision, and accuracy. The quantitative level in plant material was determined as the following order: lamiuside C (4, 3.75 mg/g dry weight) > ecdysterone (1, 1.93 mg/g) > isoacteoside (2, 1.32 mg/g) > rutin (3, 0.97 mg/g).

Anti-viral Treatment of Chronic Hepatitis B

Patients with chronic hepatitis B virus (HBV) infection are at risk for development of liver cirrhosis and hepatocellular carcinoma. The goal of antiviral therapy for chronic hepatitis B is the permanent suppression of HBV replication; loss of HBV DNA and HBeAg seroconversion. Three antiviral drugsinterferon, lamivudine and adefovir dipivoxil-are avilable now. Although they were proven to have suppressive effects on HBV replication, their antiviral effects are not satisfactory yet and durability of response is low. Emergence of drug resistant mutants is troublesome in lamivudinr therapy. Expense of drugs is another problem for long-term antiviral treatment. Development of new drugs which have stronger and durable antiviral effects and combination therapy with several antiviral drugs to reduce drug resistant mutants are anticipated.

Radioresponse of Hepatocellular Carcinoma-Treatment of Lymph Node Metastasis / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: To analyze the radioresponse of hepatocellular carcinomas (HCC), using accurate measurements of the tumor size in extrahepatic lymph node metastasis, and to obtain information for the future treatment of primary intrahepatic lesions. MATERIALS AND METHODS: Fifty-one extrahepatic lymph node metastases from primary HCCs, which could be treated by external radiotherapy alone, were included in this study. The radiation dose ranged from 30 to 51 Gy with fraction sizes of 2.0~3.0 Gy. Responses were determined by measuring the areas on CT scans 0, 1 and 3 months after the completion of radiotherapy. The median follow-up period of the surviving patients was 10 months. RESULTS: The overall response rate was 76%, and the important factors were; total dose of radiation, time dose fractionation (TDF) value and the biologically effective dose (BED). A dose of 45 Gy or higher showed an objective response rate of 93%, and if the TDF value was higher than 90, a similar result was observed. In about half (47%) of the patients the maximum response was observed at 3 months or later. The response duration was observable in 14 patients surviving 12 months or longer. Regrowth of irradiated lesions were observed in 4 (66.7%) patients among those who received less than 45 Gy, and in 4 (50%) among those who were treated with 45 Gy or more. There was a statistically significant difference in the survivals between the responders and non-responders (p=0.008). Gastrointestinal bleeding or ulceration was observed in 8 patients, including 3 with NCI common toxicity criteria grade III or higher. CONCLUSION: Radiotherapy was an effective palliative modality for extrahepatic metastasis in HCCs. A radiation dose of 45 Gy or higher (or a TDF value > or =90), was required for a major response.

A Case of Acute Hepatitis related to the Chinese Medicine Ho-Shou-Wu / 대한내과학회지

There are few reports of hepatitis related to the Chinese Medicine in Korea. Because herbal medicine contains many ingredients, it is confused what ingredient causes the hepatitis. We experienced a case of acute hepatitis developed after consumption of Chinese herbal medicine, Ho-Shou-Wu, for 75 days which contains only one component, Polygonum multiflorum, in a 55 year-old woman. And gradual recovery from hepatitis was observed after stopping the medication. Drug-induced hepatitis was diagnosed with typical clinical course and exclusion of all the possible causes of acute hepatocellular injury. We report this case with review of literature.

Experiences of Endoscopic Ultrasonography in the 5 cases with Pancreatic Insulinoma / 대한소화기내시경학회지

Of the various endocrine tumors affecting the pancreas, insulinomas and gastrinomas are the most common. In order to facilitate surgery, the localization of tumor is important. However, at the first time of presentation, the localization of tumor was often difficult by CT or ultrasonography because the tumor was relatively too small. The introduction of endoscopic ultrasonography has allowed high-resolution imaging of the pancreas that distinguishes structures as small as 2 to 3 mm in diameter. Thus, it has became easier to detect the lesion site of pancreatic endocrine tumor by endoscopic ultrasonography. We report the 5 patients who had pancreatic insulinoma which were detected and localized by endoscopic ultrasonography.
