RESUMO
BACKGROUND AND OBJECTIVE: While there are multiple studies on the anti-tumoral effects of Panax ginseng as active ingredients (one or more ginsenosides derived from the extract) or as a whole plant extract, there is a lack of studies to assess the effects Panax ginseng's of active ingredients combined with the whole plant extract. Our aim was to study the effect of whole ginseng, enriched in the anti-tumoral Rh2 component and other ginsenosides (Ginseng Rh2+), on the metastatic capacity of non-small cell lung cancer (NSCLC). METHODS: We evaluated the effects of Ginseng Rh2+ on survival, migration and motility, induction of apoptosis, and expression of its apoptosis-related proteins in non-small cell lung cancer (NSCLC) cells in vitro and on primary tumor growth and metastatic capacity in a syngeneic mouse lung cancer model in vivo. The effects of Ginseng Rh2+ on NSCLC cells were studied in vitro using: a colorimetric tetrazolium salt (XTT) assay, annexin V-FITC/PI, western blotting, wound healing motility assay, Transwell migration and cell adhesion assays. In vivo, mice were inoculated with Lewis mouse lung carcinoma cells subcutaneously to evaluate local tumor growth, or intravenously to evaluate the effects of Ginseng Rh2+ on development of experimental metastases. Mice were treated by intraperitoneal administration of Ginseng Rh2+ (0.005-0.5 g kg-1) on days 6, 10, and 14 after tumor injection. RESULTS: We found that Ginseng Rh2+ increased the apoptosis of NSCLC cells in vitro, demonstrating dose dependent down-regulation of the Bcl-2 anti-apoptotic gene and concurrent up-regulation of the Bax pro-apoptotic gene. Ginseng Rh2+ inhibited the tumor cells' capacity to attach to the ECM-related matrix and reduced cell migration. In vivo, Ginseng Rh2+ inhibited local tumor growth and reduced the development of experimental lung metastases. CONCLUSION: Our study suggests that Ginseng Rh2+ may potentially be used as a therapeutic agent for treatment of NSCLC.

OBJECTIVES: Bufonis venonum (BV) is toad venom and is the dried, white secretions of the auricular and the skin glands of toads. This study was performed to evaluate the toxicity of intravenous injection of Bufonis venonum pharmacopuncture (BVP) through a single- dose test with sprague-dawley (SD) rats. METHODS: Twenty male and 20 female 6-week-old SD rats were injected intravenously in the caudal vein with BVP or normal saline. The animals were divided into four groups with five female and five male rats per group: the control group injected with normal saline, the low-dosage group injected with 0.1 mL/animal of BVP, the medium-dosage group injected with 0.5 mL/ animal of BVP and the high-dosage group injected with 1.0 mL/animal of BVP. We performed clinical observations every day and body weight measurements on days 3, 7 and 14 after the injection. We also conducted hematology, serum biochemistry, and histological observations immediately after the observation period. RESULTS: No mortalities were observed in any experimental group. Paleness occurred in the medium- and the high-dosage groups, and congestion on tails was observed in females in the medium- and the high-dosage groups. No significant changes in weight, hematology, serum biochemistry, and histological observations that could be attributed to the intravenous injection of BVP were observed in any experimental group. CONCLUSION: The lethal dose of intravenously-administered BVP in SD rats is over 1.0 mL/animal.
RESUMO
Benign prostatic hyperplasia (BPH), which is a common disorder in aging men, involves inflammation that is associated with an imbalance between cell proliferation and cell death. Because current BPH drug treatments have undesirable side effects, the development of well-tolerated and effective alternative medicines to treat BPH is of interest. Bee venom (BV) has been used in traditional medicine to treat conditions, such as arthritis and rheumatism, and pain. Although inflammation has been associated with BPH and BV has strong anti-inflammatory effects, the effects of BV on BPH are not fully understood. Therefore, in this study, we evaluated the efficacy of BV against testosterone-induced BPH in rats. BV decreased prostate weight compared to the untreated group. In addition, BV suppressed serum dihydrotestosterone concentration levels and the levels of proliferating cell nuclear antigen in the histological analysis. Furthermore, BV significantly decreased the levels of the apoptotic suppressors, Bcl-2 and Bcl-xL, and increased the levels of the proapoptotic factors, Bax and caspase-3 activation. These results suggested that BV suppressed the development of BPH and has good potential as a treatment for BPH.

Accumulative evidence suggests ginseng extract and/or its major components, ginsenosides and compound K, a metabolized ginseng saponin, have anti-cancer effects. In the present study, the effects of a ginseng butanolic extract (GBX) and an enzymatically fortified ginseng extract (FGX), with enriched ginsenosides and compound K, on the growth of KATO3 human gastric cancer cells were investigated using a cell viability assay. While treatment with GBX at 31.25-125 mg/ml for 24 h did not affect the proliferation of KATO3 cells, FGX under the same conditions inhibited cell proliferation in a concentration-dependent manner. Furthermore, Annexin V/PI-staining and flow cytometric analysis demonstrated that the population of apoptotic KATO3 cells was increased following treatment with FGX, which was greater than in the GBX-treated cells, suggesting that FGX had a stronger apoptotic effect than GBX. To investigate the underlying mechanism of the cytostatic and cytotoxic effects of the ginseng extracts, apoptosis-associated proteins were assessed using western blot analysis. The data revealed higher expression levels of B-cell lymphoma 2-associated X protein (Bax), lower expression of nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor α (IκBα) and reduced phosphorylation of mammalian target of rapamycin (mTOR) and protein kinase B (PKB) in the FGX-treated KATO3 cells than in the GBX-treated cells. Collectively, these results demonstrated for the first time, to the best of our knowledge, that FGX had stronger anti-proliferative and pro-apoptotic effects on KATO3 cells than GBX. The anti-proliferative and/or pro-apoptotic effects of FGX appeared to be mediated via the upregulation of Bax, IκBα proteolysis (activation of nuclear factor-κB) and the blocking of mTOR and PKB signals.

OBJECTIVES: Radix Ginseng has been used for thousands of years to treat a wide variety of diseases. Radix ginseng has also been used as a traditional medicine for boosting Qi energy and tonifying the spleen and lungs. Traditionally, its effect could be obtained orally. Nowadays, a new method, the injection of herbal medicine, is being used. This study was performed to investigate the single-dose intravenous toxicity of water-soluble ginseng pharmacopuncture (WSGP) in Sprague-Dawley (SD) rats. METHODS: All experiments were carried out at Biotoxtech, an institute authorized to perform non-clinical studies under the regulation of Good Laboratory Practice (GLP). At the age of six weeks, 40 SD rats, 20 male rats and 20 female rats, were allocated into one of 4 groups according to the dosages they would receive. The WSGP was prepared in the Korean Pharmacopuncture Institute under the regulation of Korea-Good Manufacturing Practice (K-GMP). Dosages of WSGP were 0.1, 0.5 and 1.0 mL/animal for the experimental groups, and normal saline was administered to the control group. The rat's general conditions and body weights, the results of their hematological and biochemistry tests, and their necropsy and histopathological findings were investigated to identify the toxicological effect of WSGP injected intravenously. The effect was examined for 14 days after the WSGP injection. This study was performed under the approval of the Institutional Animal Ethics Committee of Biotoxtech. RESULTS: No deaths were found in this single-dose toxicity test on the intravenous injection of WSGP, and no significant changes in the rat's general conditions and body weights, the results on their hematological and biochemistry test, and their necropsy findings were observed during the test. The local area of the injection site showed minial change. The lethal dose was assumed to be over 1.0 mL/animal in both sexes. CONCLUSION: These results indicate that WSGP is safe at dosages up to 1 mL/animal.
RESUMO
OBJECTIVES: Bufonis venonum (BV) is the dried white secretions of the auricular and skin glands of the toads Bufo bufo gargarizans or Bufo melanosticus Schneider. This study was performed to evaluate the toxicity of intramuscularly- administered Bufonis venonum pharmacopuncture (BVP) and to calculate its approximate lethality through a single-dose test with Sprague-Dawley (SD) rats. METHODS: Twenty male and 20 female 6-week-old SD rats were injected intramuscularly with BVP or normal saline. The animals were divided into four groups with five female and five male rats per group: the control group injected with normal saline at 0.5 mL/animal, the low-dosage group injected with 0.125 mL/animal of BVP, the medium-dosage group injected with 0.25 mL/animal of BVP and the high-dosage group injected with 0.5 mL/animal of BVP. All injections were in the left thighs of the rats. After administration, we conducted clinical observations everyday and body weight measurements on days 3, 7 and 14 after the injection. We also carried out hematology, serum biochemistry, and histological observations on day 15 after treatment. RESULTS: No mortalities were observed in any experimental group. No significant changes in weight, hematology, serum biochemistry, and histological observations that could be attributed to the intramuscular injection of BVP were observed in any experimental group. CONCLUSION: Lethal dose of BVP administered via intramuscular injection in SD rats is over 0.5 mL/animal.
RESUMO
Lung cancer is the most common cancer and the leading cause of cancer-related deaths. Panax ginseng has long been used to treat cancer and other diseases worldwide. Most of the pharmacological actions of ginseng are attributed to a variety of ginsenosides, which are often metabolized by intestinal bacteria into more effective forms. In this study, we found that the antiproliferative activity of ginseng was increased after enzymatic processing of ginseng saponin (50% inhibitory concentration, >70 µg/ml). To elucidate the mechanism by which modified ginseng extract (MGX) induced cell death in human lung cancer cells, the gene expression profiles of A549 cells regulated by MGX were assayed using Agilent PrimeView Human Gene Expression Arrays. The expression of 17 genes involved in the regulation of cell signaling, cell metabolism, transport, and cytoskeleton-regulation was up-regulated, whereas the expression of 16 genes implicated in invasion and metastasis and cellular metabolism was down-regulated in MGX-treated A549 cells. Moreover, nuclear staining with 4',6-diamidino-2-phenylindole revealed that MGX clearly caused nuclear condensation and fragmentation which are observed in apoptosis cell. These results elucidate crucial anticancer mechanisms of MGX and provide potential new targets for the assessment of anticancer activity of MGX.

OBJECTIVES: The main objective of this study was to evaluate the anti-depressant effects of pharmacopuncture using sumsu (Bufonis venenum). METHODS: Animals were divided into three groups (control, sham, and experimental), with eight mice per group. The sham and the experimental groups were exposed to 2 hours of immobilization stress daily for 14 days. They were also injected with normal saline (sham) or subjected to pharmacopuncture with sumsu at the acupoints HT7, SP6, and GV20 (experimental). The depression or anxiety-like behaviors of the mice in each group were evaluated 1 day after treatment. RESULTS: There was no difference in locomotor activity between the groups during the open-field test; i.e., all groups had normal motor function. However, the open-field and the forced-swimming tests revealed that depression and anxiety-like behaviors were decreased significantly in the group treated with sumsu pharmacopuncture. CONCLUSION: Sumsu pharmacopuncture attenuated depressive or anxiety-like behavior in mice stressed with chronic immobilization. These results suggest that sumsu pharmacopuncture has therapeutic potential for treating neuropsychiatric disorders such as anxiety or depression disorder.
RESUMO
INTRODUCTION: Chemotherapy-induced peripheral neuropathy (CIPN) is sensory and motor nerve damage to the peripheral nervous system caused by chemotherapeutic agents. It often causes pain and other varying degrees of neuropathic symptoms accompanied by functional limitations and reduced quality of life. Currently, there is no standard treatment protocol for the treatment of CIPN. OBJECTIVE: In need of more research to develop new therapeutic options focusing on their safety, efficacy, and long-term sustained clinical effects, a pilot study of sweet bee venom pharmacopuncture (SBVP) for CIPN was conducted to build up preliminary efficacy data in the process of preparing for a future larger scale randomized controlled SBVP trial for CIPN. METHODS: We conducted a prospective case series by analyzing the clinical observations made of CIPN patients treated with SBVP. A total of 11 eligible consecutive CIPN patients who visited East-West Cancer Center from June 1, 2010, to February 28, 2011, were treated with total of six SBVP treatments given within the 3-week period. The outcomes were measured using World Health Organization Common Toxicity Criteria for Peripheral neuropathy (WHO grading system), Patient Neurotoxicity Questionnaire (PNQ), Visual Analogue System (VAS), and Health-Related Quality of Life (HRQOL) collected at the baseline, post-second, fourth, and the final treatment. Patients were followed 3 weeks into no intervention to determine the sustained effects of pharmacopuncture. RESULTS: Both of the WHO CIPN grade and PNQ scores have shown a decrease in the level of neuropathy. VAS pain level has also shown a great decrease and improvement in patients' quality of life have also been detected though modest. Changes in WHO grade, VAS and Total HRQOL scores between the baseline and after the last treatment session were significant. Changes in WHO grade, Total PNQ, PNQ-sensory, VAS, Total HRQOL, and HRQOL-functional scores between the baseline and the 3-week follow-up were significant. CONCLUSION: The positive result of the study supports the potential value of conducting a fully powered trial to explore further efficacy of SBVP for CIPN. However a single positive result within this pilot study must be interpreted with caution.

Administration of mountain ginseng (MG) extract can restore advanced cancer to a normal state. To elucidate the mechanism by which MG extract prevents the progression of lung cancer, the processes of proliferation and death of lung cancer cells (A549) were examined after treatment with MG extract. Butanol-extracted MG (BX-MG) showed a high inhibitory effect (IC(50) = 2 mg/ml) by attenuating proliferation and inducing apoptosis in lung cancer cells. By HPLC-UV analysis of BX-MG, ginsenosides, Rb1 was identified as the most abundant ginsenoside, followed by Rg1, Re, Rc and Rb2. BX-MG induced caspase-3 dependent apoptosis by inhibiting NF-κB. In addition, BX-MG activated p53 and p21, resulting in the attenuated proliferation of A549 cells. Reduced activity of the NF-κB promoter and increased activity of the p53 promoter indicate that BX-MG regulates apoptosis at the level of transcription in lung cancer cells. Furthermore, BX-MG blocked the nuclear translocation of RelA and the associated reduction in surviving. These results suggest that BX-MG inhibits lung cancer cell growth by activating tumor suppressors and inhibiting nuclear translocation of NF-κB.

Panax ginseng is a well-known herbal medicine in traditional Asian medicine. Although wild ginseng is widely accepted to be more active than cultivated ginseng in chemoprevention, little has actually been reported on the difference between wild ginseng and cultivated ginseng. Using suppressive subtraction hybridization, we cloned the p-psbB gene as a candidate target gene for a wild ginseng-specific gene. Here, we report that one of the clones isolated in this screen was the chloroplast p-psbB gene, a chlorophyll a-binding inner antenna protein in the photosystem II complex, located in the lipid matrix of the thylakoid membrane. Real-time results showed that the expression of the p-psbB gene was significantly up-regulated in wild ginseng as compared to cultivated ginseng. Thus, the p-psbB gene may be one of the important markers of wild ginseng.
RESUMO
Panax ginseng is a well-known herbal medicine in traditional Asian medicine, and wild ginseng is widely accepted to be more active than cultivated ginseng in chemoprevention. However, little has actually been reported on the difference between wild ginseng and cultivated ginseng. Thus, to identify and analyze those differences, we used suppressive subtraction hybridization (SSH) sequences with microarrays, realtime polymerase chain reaction (PCR), and reverse transcription PCRs (RT-PCRs). One of the clones isolated in this research was the chloroplast rpoC1 gene, a ß subunit of RNA polymerase. Real-time RT-PCR results showed that the expression of the rpoC1 gene was significantly upregulated in wild ginseng as compared to cultivated ginseng, so, we conclude that the rpoC1 gene may be one of the important markers of wild ginseng.
RESUMO
OBJECTIVES: Toad venom, called Chan-Su, is a traditional Oriental medicine secreted from the auricular and the skin glands of the Bufo bufo gargarizanz Cantor or B. melanosticus Schneider and has been widely used in China, Korea and other parts of Asia for the treatment of pain, heart conditions, and cancer. We examined the concentrations of the main chemical constituents within a commerciallyavailable toad venom product and compared the levels for different extraction methods. METHODS: Toad venom was extracted using either cold or hot water, ethanol (EtOH), methanol (MeOH), or ethyl acetate (EtOAc), was fractionated using precipitation or reflux, and was then analyzed using thin layer chromatography (TLC), high-performance liquid chromatography (HTLC), and liquid chroma-tography - mass spectrometry (LC-MS). Individual components were identified by comparisons of the retention times, the ultraviolet spectra, and mass spectras and differences in chemical constituents for different solvents and extraction methods are presented. RESULTS: Components with authentic standards, including serotonin and bufodienolides (cinobufagen, bufalin, cinobufalin, and resibufogenin), were detected. The water extract of toad venom contained the greatest amount of serotonin (75.7 ± 0.1 mg/g), but very small amounts of bufodienolides (3.8 ± 0.0 mg/g). In contrast, the use of MeOH or EtOH extraction solutions resulted in 5-26 times higher concentrations of bufodienolides, with only trace amounts of serotonin. The relative and the absolute concentrations of the component also varied based on the extraction method; i.e., EtOH extracts yielded the greatest total amounts of bufodienolides, and EtOAc precipitation had the lowest amounts of bufodienolides. CONCLUSIONS: Toad venom consists of serotonin and several bufodienolides, and the choice of solvent to extract chemical the constituents is important as a way to enrich the purported active components for treating different conditions.
RESUMO
OBJECTIVE: This is a case series reporting safety and degree of response to 1 dose level of sweet bee venom pharmacopuncture (SBVP) or melittin as a symptom-control therapy for chemotherapy-induced peripheral neuropathy (CIPN). SETTING: All treatments were conducted at the East West Cancer Center (EWCC), Dunsan Oriental Hospital, Daejeon University, Republic of Korea, an institution that uses complementary therapies for cancer patients. METHODS: Five consecutive patients with CIPN were referred to the EWCC from March 20, 2010, to April 10, 2010. Patients with World Health Organization Chemotherapy-Induced Peripheral Neuropathy (WHO CIPN) grade 2 or more were treated with SBVP for 3 treatment sessions over a 1-week period. Measures of efficacy and safety. Validated Visual Analog System (VAS) pain scale, WHO CIPN grade, and Functional Assessment of Cancer Therapy-General (FACT-G) were compared before and after the 1-week course of treatment. To ensure the safety of SBVP, pretreatment skin response tests were given to patients to avoid any potential anaphylactic adverse effects. All patients were closely examined for any allergenic responses following each treatment session. RESULTS: One patient discontinued treatment after the first session, and 4 patients completed all treatment sessions. Using each patient as their own comparator, marked improvements of VAS, WHO CIPN grade, and physical section scores of FACT-G were seen in 3 patients. Most important, there were no related adverse side effects found. CONCLUSION: This safety results of the SBVP therapy merits further investigations in a larger size trial for it to develop into a potential intervention for managing CIPN symptoms. This study will be extended to a dose-response evaluation to further establish safety and response, prior to a randomized trial.

Ginseng is one of the most widely used herbal medicines in the world. Wild ginseng is thought to be more effective than cultivated ginseng in chemoprevention; however, little has been reported on the differences between wild and cultivated ginseng. In the present study we used suppressive subtractive hybridization to identify wild ginseng-specific genes. One of the clones isolated in this screen was the NRT2 gene (designated pNRT2), a high-affinity nitrate transporter. Real-time reverse transcription-polymerase chain reaction results showed that pNRT2 expression was significantly upregulated in wild ginseng compared with cultivated ginseng. However, pNRT2 mRNA levels were similar between mountain cultivated ginseng and mountain wild ginseng. Nitrate is an important nitrogen source for plant growth, and its soil levels can vary in wild environments; thus it is conceivable that pNRT2 expression is upregulated in wild ginseng and may be an important marker of wild ginseng.

This study aims to observe the efficacy of mountain Ginseng (Panax ginseng C.A. Meyer) pharmacopuncture (MGP) on cancer patients using different delivery methods of acupoint injection and intravenous infusion. Six non-small cell lung cancer (NSCLC) patients who met the eligibility criteria were observed. Two patients were continuously infused with MGP (20 mL/day) intravenously, and the other two patients were injected with MGP (10 mL/day) on acupoint LU1 bi-lateral continuously. The remaining two patients received MGP therapy using both methods of delivery. Results were followed by computed tomography (CT) after every cycle; each cycle lasted for 28 days. Two patients infused intravenously showed stable disease and two patients injected on LU1 showed progressive disease. Two patients treated using both methods showed stable disease during the intravenous infusion period and progressive disease during the intraacupuncture injection period. One patient showed progressive disease in the latest chest CT in spite of receiving MGP intravenous infusion. We suggested that MGP may be more effective when used as an intravenous infusion rather than acupoint injection in NSCLC patients.

After administering cultivated wild ginseng pharmacopuncture (CWGP) to advanced cancer patients, the response and survival rate were evaluated. This prospective observational pilot study of CWGP was conducted at the East-West Cancer Center of Daejeon University, Dunsan Oriental Hospital from August 2007 to June 2008. Seven patients were recruited for this study. One cycle of treatment consisted of intravenous infusion of CWGP (20 mL/day) for 2 weeks with an expected treatment duration of four cycles (60 days, 2 months). Blood tests were conducted every cycle and computed tomography was performed every second cycle as follow-up. Overall survival was measured from initial administration of CWGP to death. We used the international standards provided by the Response Evaluation Criteria in Solid Tumors for measuring response rate and Kaplan-Meier analysis to determine statistical significance. Seven patients received a total of 55 cycles (1 with 1 cycle, 2 with 2 cycles, 1 with 3 cycles, 2 with 13 cycles, 1 with 20 cycles). One-year survival rate was 57.1%, and the median survival time was 544 days. Among these patients, two non-small cell lung carcinoma patients and one advanced gastric adenocarcinoma patient showed stable disease. Two patients dropped out after the first and second cycles of treatment without receiving a new computed tomography scan. Two patients showed progressive disease. Although a further large scale study is necessary, CWGP showed potential as an effective treatment for two non-small cell lung carcinoma patients and one advanced gastric carcinoma patient.
