Objectives: The aim of this study was to review the clinical research on antihypertensive effects of Korean herbal medicines that function by inducing diuresis. Methods: Literature searches were performed using PubMed, Cochrane, CNKI, Wanfang, Cinii, Oasis, KISS, NDSL, RISS, DBPia, with the keywords "利水", "利尿", "高血壓", "hypertension", and "lishui." The search range included only randomized controlled trials that verified the effects of Korean herbal medicine interventions on hypertension. The selected studies were assessed by risk of bias (RoB). Results: 26 reports were selected from a total of 532 identified. For these reports, meta-analysis was performed using Revman 5.3. From this analysis, it was observed that the combined treatment of Korean medicine and antihypertensive drugs had a significantly higher total effective rate (TER) and improvement in systolic blood pressure (SBP) and diastolic blood pressure (DBP) than did the use of a single antihypertensive drug. The risk ratio of TER for lowering blood pressure was 1.25. The mean differences of SBP, DBP were -19.63 mm Hg (95% confidential interval (CI), -22.45 mm Hg, -16.80 mm Hg, p<0.00001), and -5.39 mm Hg (95% CI, -7.36 mm Hg, -3.42 mm Hg, p<0.00001) respectively. The use of Korean medicine only did not improve blood pressure, as compared to the use of an antihypertensive drug. Most of items of RoB were unclear, and the methodological quality was low. Conclusions: The combination of antihypertensive drugs and Korean medical treatment can effectively improve SBP, DBP, and TER. This finding could be widely utilized in clinical practice in Korean medicine.

Cancer is one of the major dreaded diseases causing high mortality. Lung cancer is second in position of all cancer related deaths and mainly divided into two morphologic sub-types: small-cell lung cancer and non-small cell lung cancer (NSCLC). NSCLC is an aggressive neoplasm which hardly responds to any conventional chemotherapy. Epidermal growth factor receptor (EGFR) belongs to the ErbB family of receptor tyrosine kinase that is mainly over-expressed in NSCLC. EGFR is mainly involved in the pathogenesis and progression of different carcinoma. In vivo and in vitro studies suggest that EGFR and EGF like peptides are often over-expressed in human NSCLC and these proteins are able to induce cell transformation. The conventional therapies mostly inhibit the EGFR activity and expression level in human NSCLC with the use of some EGFR-inhibitors like HKI-272, EKB569, CL-387785 etc. and some synthetic chemotherapeutic drugs like erlotinib, gefitinib, plumbagin, docetaxel, cisplatin etc., alone or in combination of two or more drugs. These therapies selectively act by competitive inhibition of the binding of adenosine triphosphate to the tyrosine kinase domain of the EGFR, resulting in inhibition of the EGFR signaling pathway. But these chemotherapeutic drugs have some cytotoxic activities to the normal cells and have some adverse side-effects. Recent studies on some traditional alternative therapies including some herbal and plant extracts, active ingredients like curcumin, different homeopathic drugs, etc. can target EGFR-signalling in NSCLC with less toxic side-effects are being currently developed.

The aim of this study was to investigate the feasibility and optimize permeability of slim patch type as a transdermal delivery system of caffein. Slim patch type was formulated and tested in modified Franz diffusion cell across cellulose membrane and hairless mouse skin in pH 5.8 phosphate buffer solution (PBS). The effect of $Pharmsolv^{\circledR}$ and drug concentration on permeation at four model, 1,2% $Pharmsolv^{\circledR}$ with $0.12\;mg/cm^2$ caffein and 0.12, $1.2\;mg/cm^2$ caffein with 2% $Pharmsolv^{\circledR}$ through hairless mouse skin was studied in vitro. The release of caffein from slim patch with various loading was fitted by the Higuchi's diffusion equation. The result showed that chemical $Pharmsolv^{\circledR}$ produced a large and significant increase of permeation. The effect of 2% $Pharmsolv^{\circledR}$ on permeation of caffein was greater about 10-fold greater than 1% $Pharmsolv^{\circledR}$ in first 60 minutes. The effect of drug concentration, however, was lower than that produced by chemical $Pharmsolv^{\circledR}$. Within the tested system, the most efficient combination for caffein slim patch type was $0.12\;mg/cm^2$ caffein with 2% $Pharmsolv^{\circledR},$ although $1.2\;mg/cm^2$ caffein with 2% $Pharmsolv^{\circledR}$ showed highest amounts permeation, because permeated percentages were significantly lower about $1/4{\sim}1/5$ times.

Although the functional ingredient has been evaluated by the Korea Food and Drug Administration (KFDA) based on scientific evidence, the levels of scientific evidence and consistency of the results might vary according to emerging data. Therefore, periodic re-evaluation may be needed for some functional ingredients. In this study, we re-evaluated scientific evidence for the antioxidant activity of coenzyme Q10 as a functional ingredient in health functional food. Literature searches were conducted using the Medline and Cochrane, KISS, and IBIDS databases for the years 1955-2010 with the search term of coenzyme Q10 in combination with antioxidant. The search was limited to human studies published in Korean, English, and Japanese. Using the KFDA's evidence based evaluation system for scientific evaluation of health claims, 33 human studies were identified and reviewed in order to evaluate the strength of the evidence supporting a relation between coenzyme Q10 and antioxidant activity. Among 33 studies, significant effects for antioxidant activities were reported in 22 studies and their daily intake amount was 60 to 300 mg. Based on this systematic review, we concluded that there was possible evidence to support a relation between coenzyme Q10 intake and antioxidant activities. However, because inconsistent results have recently been reported, future studies should be monitored.

Doxorubicin (DOX) is one of the most effective anticancer agents used for the treatment of multiple cancers; however, its use is limited by its short half-life and adverse drug reactions, especially cardiotoxicity. In this study, we found that the conjugate of DOX with APTA12 (Gemcitabine incorporated G-quadruplex aptamer) was significantly more cancer selective and cytotoxic than DOX. The conjugate had an affinity for nucleolin, with higher uptake and retention into the cancer cells than those of DOX. Further, it was localized to the nucleus, which is the target site of DOX. Owing to its mechanism of action, DOX has the ability to intercalate into the nucleotides thus making it a suitable drug to form a conjugate with cancer selective aptamers such as APTA12. The conjugation can lead to selectively accumulate in the cancer cells thus decreasing its potential nonspecific as well as cardiotoxic side effects. The aim of this study was to prepare a conjugate of DOX with APTA12 and assess the chemotherapeutic properties of the conjugate specific to cancer cells. The DOX-APTA12 conjugate was prepared by incubation and its cytotoxicity in MCF-10A (non-cancerous mammary cells) and MDA-MB-231 (breast cancer cells) was assessed. The results indicate that DOX-APTA12 conjugate is a potential option for chemotherapy especially for nucleolin expressing breast cancer with reduced doxorubicin associated side effects.

Objective : Endodermal sinus tumor or yolk sac tumor is an uncommon malignant germ-cell neoplasm. This tumor was originally described as a germ cell tumor of the ovary or the testis. Intracranial endodermal sinus tumor is extremely rare and usually develop in the pineal or suprasellar regions. The authors evaluated the effect of adjuvant therapy(chemotherapy combined with radiotherapy) and radical removal of intracranial endodermal sinus tumors. Material and Methods : Between 1996 and 2001, four patients of intracranial endodermal sinus tumor were diagnosed with tumor marker(AFP) and biopsy. Three patients were treated with surgical removal and chemotherapy with cisplatin($20mg/m^2$), etoposide($100mg/m^2$) and bleomycin($15mg/m^2$) as well as external beam radiation therapy. We compared the management problems for these tumors. Result : In all three patients the tumor size and the level of tumor marker decresed during initial adjuvant therapy. However, Tumors showed regrowth with elevated AFP of serum and CSF possibly related to delayed chemotherapeutic treatment or inadequate administration of chemotherapeutic drugs due to severe bone marrow suppression. An additional chemotherapy and external radiation therapy were given, but tumors could not be controlled with leptomeningeal seeding. Conclusion : Radiotherapy is considered to be less effective. The combination chemotherapy with PVB(cisplatin, vinblastine, bleomycine) or PE(cisplatin, etoposide) is considered to be value in prolongation of the survival rate. But the role of chemotherapy in this tumor has not yet been clarified due to bone marrow suppression and drug resistance. Further study with large series of this tumor is necessary to establish the optimal management.

Vemurafenib has recently been used as drug for treatment of melanomas with $BRAF^{V600E}$ mutation. Unfortunately, treatment with only vemurafenib has not been sufficiently effective, with recurrence after a short period. In this study, three vemurafenib-resistant $BRAF^{V600E}$ melanoma cell lines, $A375P^R$, $A375M^R$ and SKMEL-$28^R$, were established from the original A375P, A375M and SKMEL-28 cell lines. Examination of the molecular mechanisms showed that the phosphorylation levels of MEK and ERK, which play key roles in the RAS/RAF/MEK/ERK signaling pathway, were reduced in these three cell lines, with increased phosphorylation levels of pAKTs limited to SKMEL-$28^R$ cells. Treatment of SKMEL-$28^R$ cells with 100 nM paclitaxel resulted in increased apoptosis and decreased cellular proliferation, invasion and colony formation via reduction of expression levels of EGFR and pAKTs. Moreover, vemurafenib-induced pAKTs in SKMEL-$28^R$ were decreased by treatment with an AKT inhibitor, MK-2206. Taken together, our results revealed that resistance mechanisms of $BRAF^{V600E}$-mutation melanoma cells to vemurafenib depended on the cell type. Our results suggested that paclitaxel should be considered as a drug in combination with vemurafenib to treat melanoma cells.

Several chemotherapeutic agents are known to develop pulmonary toxicities in cancer patients, although the frequency of incidence varies. Cyclophosphamide is a commonly encountered agent that is toxic to the lung. Additionally, granulocyte colony-stimulating factor (G-CSF) being used for the recovery from neutropenia can exacerbate lung injury. However, most of the patients reported previously that the drug-induced interstitial pneumonitis were developed after three to four cycles of chemotherapy. Hereby, we report a case of peripheral T cell lymphoma which rapidly developed a fatal interstitial pneumonitis after the first cycle of combined chemotherapy with cyclophosphamide, adriamycin, vincristine, prednisolone, and etoposide and the patient had also treated with G-CSF during neutropenic period.

We have conducted questionnaire and measured serum kidney function tests on 156 patients whom have received a treatment at a local Oriental medicine clinic in Seoul from Sept. 1, 2002 to Dec. 31, 2002. Patients were categorized into five groups. The groups are control(10 samples), herbal extract group(41 samples), herbal pills group(5samples), western medicines(45samples), and combination group(55 samples). This study was conducted to investigate how these treatment methods can affect the kidney functions. Following results were obtained : 1) Most of the research subjects were male(103 individuals) living in large urban area, with a drinking habit, highly educated, and with normal marriage. For the treatment history, 45 individuals received western medicine treatment(28.85%), 46 with Oriental medicine(29.49%), and 55patients (35.26%) experienced both forms of the treatment. 2) For measuring Mean(SD) of serum kidney functions for all the research subjects, Bun was 12.16(3.90)g/dl, 0.51(0.19) g/dl for Creatinine, and 4.64(1.49)g/dl for Uric acid. All the measurements were within the normal range. 3) Confounding variables which may affect the kidney functions such as age, smoking, drinking, occupation, and residency were eliminated in calculation and no significant differences were witnessed between the control and experiment groups. 4) In measuring affects of treatment duration on the kidney functions, no statistical significances were shown in multiple regression's ${\beta}(SE)$ values. 5) Correlations affecting the kidney functions are duration of drinking, drinking volume per round, drinking volume per week, smoking, gender, and age difference caused significant correlations. From the above results, we can deduce that taking herbal and western medicine didn't cause significant effects between the control and experiment groups in the kidney functions. Further research is needed in this field to verify this evidence by adding odds ratios and etc.
