Objective: To compare efficacy and safety profile of vinorelbine, ifosfamide and cisplatin (NIP) with etoposide and cisplatin (EP) in the treatment of advanced combined small cell lung cancer (c-SCLC). Methods: From January 2006 to December 2010, 176 patients with advanced c-SCLC were enrolled. The primary endpoint was overall survival (OS) and the secondary endpoints were progression free survival (PFS), response rate (RR) and toxicity. Results: Overall RR was 30.0% in the NIP and 38.5% in the EP group; there was no significant difference (P=0.236). The PFS in the EP group was little longer than that of NIP group, with 6.5 months for EP and 6.0 months for NIP group, but the difference was statistically non-significant (P=0.163). The median OS and one year survival rates were 10.4 months and 36.3% for NIP group, and 10.8 months and 49.0% for EP respectively, EP showing a survival benefit, although this was not statistically significant. Both groups well tolerated the adverse effects. The incidence of grade I-II leucopenia and alopecia in the NIP group was significantly higher than that of EP group (32.5% vs. 10.4% (P<0.001, 35.0% vs. 12.5%, P<0.001). Conclusion: the ORR, PFS and OS in NIP were slightly inferior to traditional regimen EP. The toxicity of NIP can be considered tolerable. The usage of three drugs combination in the treatment of mixed SCLC remains uncertain. Nevertheless, the results need to be further confirmed by large, prospective clinical trials.

The development of chemopreventive approaches using a concoction of phytochemicals is potentially viable for combating many types of cancer including colon carcinogenesis. This study evaluated the anti-proliferative effects of ginger and Gelam honey and its efficacy in enhancing the anti-cancer effects of 5-FU (5-fluorouracil) against a colorectal cancer cell line, HCT 116. Cell viability was measured via MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulphenyl)-2H-tetrazolium) assay showing ginger inhibiting the growth of HCT 116 cells more potently ($IC_{50}$ of 3mg/mL) in comparison to Gelam honey ($IC_{50}$ of 75mg/mL). Combined treatment of the two compounds (3mg/mL ginger+75mg/mL Gelam honey) synergistically lowered the $IC_{50}$ of Gelam honey to 22mg/mL. Combination with 35 mg/mL Gelam honey markedly enhanced 5-FU inhibiting effects on the growth of HCT 116 cells. Subsequent analysis on the induction of cellular apoptosis suggested that individual treatment of ginger and Gelam honey produced higher apoptosis than 5-FU alone. In addition, treatment with the combination of two natural compounds increased the apoptotic rate of HCT 116 cells dose-dependently while treatment of either ginger or Gelam honey combined with 5-FU only showed modest changes. Combination index analysis showed the combination effect of both natural compounds to be synergistic in their inhibitory action against HCT 116 colon cancer cells (CI 0.96 < 1). In conclusion, combined treatment of Gelam honey and ginger extract could potentially enhance the chemotherapeutic effect of 5-FU against colorectal cancer.

Objectives: This review plans to assess the efficacy and effectiveness of oriental medicine for the treatment of Ovarian Hyperstimulation Syndrome (OHSS) through literature research and overview. Methods: Database searching was conducted to identify relevant randomized controlled trials (RCTs) on oriental medicine for the treatment of Ovarian Hyperstimulation Syndrome. Studies were searched from Journal of Korean Obstetrics and Gynecology, Korean Medical Database, Korean studies Information Service System, China National Knowledge Infrastructure, Cochrane library, PubMed and EmBase up to 21^st May, 2020. Results: Seventeen studies were finally selected. Fifteen studies intervened with oral Chinese herb medicine, two studies intervened with acupuncture and moxibustion. Nine studies concluded that intervention with oriental medicine significantly relieved OHSS symptoms. Three studies reporting ovary diameter, four studies reporting abdominal circumference and other four studies reporting pelvic effusion showed significant reduction compared to control groups. Six studies showed significantly shorter duration for hospitalization in intervention groups. Only one study showed significantly higher pregnancy rate. Factors related with vascular permeability and blood cell coagulation were significantly lowered in intervention groups in general. Conclusions: From seventeen studies, oriental medicine relieved OHSS symptoms and showed treatment effectiveness. Further strictly designed studies and long-term observed studies are needed to establish evidences.

공적연금제도는 세대간 연대에 기반한 세대간 계약을 구체화한다. 지난 두 차례의 국민연금 개혁은 수익과 부담을 둘러싼 세대간 공평성에 주목하여, 보장성을 낮추고 미래세대의 부담을 줄였다. 그러나 좁은 의미의 세대간 형평성을 강조한 개혁의 결과, 국민연금은 세대간 연대 확대에 기여하지 못하고 있다. 이 연구는 한국사회에서 세대간 계약의 내용 변화를 살펴보고, 좁은 의미의 세대간 형평성이 아니라 포괄적인 시각에서 사회적 연대에 기여하도록 세대간 계약을 재구성하는 노력이 필요하다고 제안한다. 즉, 연금제도를 통한 사회적 계약은 세대간 공평성에만 집중하는 것이 아니라 사회적 지속성의 관점에서 세대간 연대의 실효성과 안정성을 높이는 방향으로 재구성되어야 한다는 것이다. 그 일환으로 후세대에 대한 사회투자 강화를 제안하였다. 이는 세대간 자원 분배의 갈등적 요소를 줄이는 동시에 인구, 고용 부문의 변화를 통해 재정안정성을 제고할 수 있는 정책 수단 중 하나일 것이다.

HMG-CoA reductase는 체내 콜레스테롤 생합성에 있어서 속도제한단계(율속) 효소이다. 본 연구는 HMG-CoA reductase에 대한 이소플라본 배당체의 저해 효과를 연구하였다. $100{\mu}M$의 농도에서 genistein-7-O-triglucoside(G2-genistin)는 HMG-CoA reductase 활성을 약 18% 정도 저해하였으나, daidzein-7-O-triglucoside는 저해 효과를 갖지 않았다. 시리아햄스터 HMG-CoA reductase의 반응속도 실험에서 G2-genistin은 농도에 관계없이 $V_{max}$의 저해 정도가 일정하였으며, 이것은 G2-genistin이 HMG-CoA reductase의 경쟁적 저해제로 작용함을 시사하고 HMG-CoA reductase의 활성을 직접적으로 저해함으로써 혈중 콜레스테롤 함량을 감소시킬 수 있음을 예상할 수 있다.

Background: To achieve the efficacy and toxic effects of concomitant FP chemoradiotherapy regimen by means of response and survival in patients with advanced head and neck cancer. Patient and Method: Thirty-three previously untreated patients with newly diagnosed advanced head and neck cancer were retrospectively reviewed. Results: Thirty-one patients were evaluable for the tumor response. Total response rate was 93%(complete response 60%, partial response 33%). Disease free survival was 37 month and 3-year overall survival was 63%. Grade 3 or 4 stomatitis was observed in 83% and appeared as the dose limiting toxicity for this regimen. Conclusion: Concomitant chemoradiotherapy with cisplastin and 5-fluorouracil is effective as primary therapy for advanced head and neck cancer. The majority of patients experienced severe stomatitis. Identification of less toxic regiment and improved disease control emerge as important future research goals.

The effect of biological control agent Bacillus sp. (BAC03-3-1, BAC03-3-2, BAC02-4) on pre- and postemergence Sclerotinia rot of perilla (Perilla frutescens var. japonica) caused by Sclerotinia sclerotiorum was determined from greenhouse field trials. The ability of this antagonist to reduce germination of sclerotia of S. sclerotiorum was also evaluated. In the greenhouse, suspension of BAC03-3-1 application as root drench of perilla, which provided as little as 10$\^$7/ cells/ $m\ell$ per gram of soil, significantly increased plant stand in pathogen-infested soil over that in the untreated control. All three isolates reduced the germination of sclerotia of S. sclerotiorum in loamy sand soils in the greenhouse. In loamy sand amended with rice bran the sclerotial germination was inversely correlated (r = -0.79) with perilla stand in the greenhouse. However, a higher rate of bacterial suspension with rice bran(Ig dwt./100g soil) than that applied with bacterial suspensions only was necessary to achieve a comparable reduction in sclerotial germination. In field study, all three isolates added to soil to provide 10$\^$7/ cells/$m\ell$ per gram significantly prevented Sclerotinia rot (73-85％) after 35 days of growth. The isolate BAC02-4, BAC03-3-1 and BAC03-3-2 gave final stands of 65 to 75, 60 to 70, and 55 to 60％, respectively. The addition of rice bran(1 ％) to loamy sand in the field resulted in a 10-fold increase in propagule numbers of the three isolates within 10 days of application.

Purpose : To assess the efficacy and toxicity of the preoperative radiotherapy with or without chemotherapy in locally advanced rectal cancer Methods : Forty three patients (clinically diagnosed stages above or equal to Astler-Coiler stage B2 without distant metastasis) were assigned to preoperative radiotherapy alone arm (n=16) or combined preoperative radiotherapy and chemotherapy arm (n=27). Preoperative radiotherapy of 4500 cGy to whole pel-vis +/-540 cGy boost to primary site and concurrent chemotherapy of 2 cycles of 5-FU (500 mg/$m^2$) and leucovorin (20 mg/$m^2$) were used. Fifteen patients of preoperative radiotherapy alone arm and 19 of combined arm received surgical resection after preoperative treatment. Results : During the preoperative treatment, no significant complication was developed in both groups. Pathologic results were as follows; complete remission 1, Bl 1, B2 6, C1 2, C2, 5 in preoperative radiotherapy alone arm and complete remission 2, Bl 8, B2 4, C2 3, D 2 in combined arm. Postoperative complications were delayed perineal wound healing in three patients, intestinal obstruction in three patients (one managed by conservative medical treatment, two by surgical treatment). Conclusion : The combined preoperative radiotherapy and chemotherapy arm was more effective in pathological response and lymph node negativity rate than the preoperative radiotherapy alone arm. Both the preoperative radiotherapy alone arm and the combined arm were generally well tolerated and did not result in an increased postoperative morbidity.

Inferior alveolar nerve block using lidocaine is the most frequent local anesthetic method in the dental treatment, but clinically it is not always successful. The 2% lidocaine cartridge has been used commonly in dental anesthesia. It contains vasoconstrictor and antioxidant, which presents low pH which provides chemical stability and longer shelf life. But alkalinized local anesthetics has less tissue trauma, easier dissociation of the non-ionized base which penetrates nerve sheath, rapid onset and more intensity. In this study, in inferior alveolar nerve block, alkalinized lidocaine using sodium bicarbonate (experimental group) is compared with plain lidocaine (control group) about injection pain, anesthetic onset, duration and postinjection discomfort. In inferior alveolar nerve block, alkalinized lidocaine using sodium bicarbonate showed lower injection pain. There was significant difference statistically from plain lidocaine(p=0.019). Comparing with plain lidocaine, alkalinized lidocaine produced more rapid onset (lip & pulp anesthetic onset), there was no significant difference(p>0.05). but there was boundary significance (0.050.05). These results suggest that addition of sodium bicarbonate to 2% lidocaine(1:100,000 epinephrine) for inferior alveolar nerve block is more effective for reduction of injection pain and onset time.
