Rhus verniciflua Stokes (RVS) is a widely used herbal plant with various biological properties. Our previous study using in vitro platelet aggregation in whole blood showed that the fractions of RVS had strong anti-aggregatory activity. In this study, using in vitro platelet aggregation in PRP and coagulation parameters, to investigate the anti-platelet activity and anticagulant effects of RVS ethyl acetate layer, the layer was subsequently fractionated by ODS columm chromatograph (50％ MeOH).

Alcohol oxidation activities and optimization of extraction conditions of Rrhus verniciflua Stokes (RVS) extract were evaluated for the development of a functional biomaterial for improving liver function. When alcohol oxidation activities of RVS was analyzed, the Rrhus verniciflua Stokes bark (RVSB) were higher than the Rrhus verniciflua Stokes heartwood (RVSH). Alcohol oxidation activity value of RVSB increased in a concentration-dependent manner. In the comparative analysis between Hovenia dulcis Thunb (HOT) and Alnus japonica Steud (AJS) which was reported as a alcohol oxidation material, alcohol oxidation activity is much higher than the others. The experimental conditions were optimized for alcohol oxidation-active components production from RVSB. The extraction conditions such as temperature, time, pH and particle size were performed. It was recommended to extract the alcohol oxidation-active components from RVSB by hot water (pH 7.0) at $85^{\circ}C$ for 8 hours.

The study was conducted to investigate the correlation and regression analysis between the factors - diameter, hight and crown width - and collection amount of Rhus lacquer by the sex of Rhus verniciflua. The relationship between the diameter and the collection amount of the lacquer by the sex of the lacquer tree indicated that, for both of the male and the female, the lacquer amount was likely to increase as the diameter got larger. In general, the male trees tended towards the higher amount of the lacquer than the female. The relationship between the crown width and the collection amount of the lacquer by the sex showed little difference. As the crown became wider, however, the lacquer amount showed the increasing trend. The regression analysis by the sex of the tree indicated that the major factors of the female had larger influence on the lacquer amount than those of the male. The no differences of statistical significance were found among the diameter, the height, the crown width, and the lacquer amount.

Renal cell carcinoma(RCC) is one of the major malignant renal cell tumors. Although RCC can metastasize to almost every organ, the most common metastatic sites are the lung parenchyma, the bones, the liver, and the brain. Adrenal metastasis from RCC is extremely rare. Adrenal metastasis from RCC shows poor prognosis, with little benefit from chemotherapy, radiation therapy, hormone therapy or immunotherapy. In this report, we describe a case of an RCC patient who showed lung and adrenal metastasis. The patient underwent left nephrectomy and chemotherapy(sunitinib), which were not effective. He refused further conventional medical treatment, and instead started treatment with Traditional Korean Medicine using allergen-removed Rhus verniciflua Stokes. After about 3 months of this treatment, the size of the adrenal tumor had decreased significantly with good performance status. Further study will be needed to demonstrate the tumor regression effect of allergen-removed Rhus verniciflua Stokes on patients with metastatic renal cell carcinoma.

Background : Lung cancer is one of the most common malignancy in the world. Types of lung cancer are Non small cell lung cancer and small cell lung cancer. Subtypes of Non small cell lung cancer are adenocarcinoma, squamous cell carcinoma and large cell carcinoma. Knowing the type of lung cancer is important in determining both treatment and prognosis. Recently, due to newly developed anti-cancer drugs, squamous cell carcinoma has relatively poor prognosis than non-squamous cell carcinoma. Case : We report a squamous cell lung cancer case treated with allergen removed Rhus verniciflua Stokes (aRVS) extract. The patients initially diagnosed stage squamous cell lung carcinoma, but she refused recommended operation. She initiated aRVS extract monotherapy in October. 2006. The follow up Computed tomography in March. 2007, she diagnosed stable disease of tumor response on aRVS treatment. However, this case was lost to follow up for 6 months while she was treated with tomotherapy. In October 2007, she came back to our cancer center after diagnosed stage IV metastasized lung to lung, and aRVS monotherapy was restarted. She had survived 2 years after metastasis of squamous cell lung carcinoma. Conclusion : Allergen removed Rhus verniciflua Stokes(aRVS) sucessfully prolonged overall survival of a squamous cell lung cancer patient.

The heartwoods of Rhus verniciflua was extracted with $H_2O$ and the concentrated extract was partitioned with $CHCl_3$, EtOAc, n-BuOH and $H_2O$, successively. From the EtOAc and n-BuOH fractions, four compounds were isolated through the repeated silica gel, ODS and Sephadex LH-20 column chromatographies. They were determined as sinapyl aldehyde (1), 2,4-dihydroxybenzaldehyde (2), 2,4-dihydroxybenzoic acid (3) and 2,4-dihydroxyphenylglyoxylic acid (4) on the basis of spectroscopic data, respectively. Among the isolated compounds, sinapyl aldehyde $(34.7{\pm}0.6%)$ and 2,4-dihydroxyphenylglyoxylic acid $(43.8{\pm}0.9%)$ showed the strong antioxidative activity than artificial antioxidant BHT $(14.4{\pm}0.3%)$ in DPPH radical scavenging activity.

Objective : We introduce a case of non-small cell lung cancer patient treated with allergen removed Rhus verniciflua Stokes. Methods : This patient started Allergen-removed Rhus Verniciflua Stokes from Feb 2010 right after his firstline chemotherapy, and maintained his Oriental medicine regimen until now. Results : It shows 12.0 months of progression-free-survival since starting point of maintenance chemotherapy, and 9.3 months of overall-survival since progression disease after 2nd chemotherapy, compared with 6.3 months of its known overall survival. Conclusion : Allergen removed Rhus verniciflua Stokes prolonged overall survival and slowed disease progression of a non-small cell lung cancer patient.

This case report documents a case in which the administration of an herbal product, an extract of the lacquer tree, Rhus verniciflua Stokes was related with a prolonged survival in a elderly advanced non-small cell lung cancer(NSCLC) patient. A 79-year-old man who had been diagnosed with advanced NSCLC refused conventional therapy and treatment with the allergen-removed Rhus verniciflua Stokes(aRVS) had continued from September 2007 to July 2010. He had survived for 35 months after the administration of aRVS and maintained good performance status with European Cooperative Oncology Group performance status(ECOG PS) of 1. This case suggests that aRVS be alternative treatment for the elderly advanced NSCLC patients.

Papillary thyroid carcinoma is the most common type of thyroid malignancy. It has better prognosis and rarer incidence of distant metastasis than other types of thyroid malignancy. However, once distant metastasis happens, its result will be bad. They mostly spread to the lungs and bones. and rarely to the brain. We report a patient with a papillary thyroid carcinoma metastasis to the lymph nodes. the ribs. the brain, and the lungs. The patient underwent total thyroidectomy, radioiodine ablation, rib partial resection, and lung wedge resection. However, upon progress of metastasis. the patient insisted on being treated with traditional Korean medical treatment using allergen-removed Rhus Verniciflua Stokes (A-RVS) instead of the conventional treatment including chemotherapy. The size of the tumor partly decreased, and the patient showed no side effects. This case report brings forth the importance of a thorough study in papillary thyroid carcinomas and their metastasis from the traditional Korean medical point of view, along with the long-term effect of allergen-removed Rhus Verniciflua Stokes (A-RVS).
