This experiment was performed to investigate whether the combined-preparation of water extracts of germinated brown rice (WGR), water extracts of cultured mountain ginseng (WCG) and 70% ethanol extracts of Longanae Arillus (ELA) has hypnotic effects and/or enhances pentobarbital-induced sleep behaviors through the GABAergic system. The combined-preparation of WGR and WCG reduced sleep latency and prolonged sleep time induced by pentobarbital. ELA also reduced sleep latency and prolonged sleep time induced by pentobarbital. However, WGR or WCG itself did not induce sleep. The combined-preparation of WGR, WCG and ELA strongly reduced sleep latency and prolonged sleep time via chloride influx into primary cultured cerebellar granule cells. In conclusion, the combined-preparation of WGR, WCG and ELA augments pentobarbital-induced sleep behaviors through the modification of GABAergic system.

Lung abscess is often ocuured by aspiration of infectious secretion in stroke patients that has symptom of dysphagia. So we studied the effects of combined eastern and western treatment in lung abscess patient combined with stroke. We performed both antibiotic therapy and herbal medication in a lung abscess patient. We compared a chest x-ray film of early stage of disease with a film of after stage of disease, also compared change of symptom-cough, sputum, flank pain, blood phlem. After dispending antibiotic therapy and herbal medication, a lung abscess patient improved symptoms and in result of chest x-ray. The above results suggest that combined eastern and western trearment can have good effects on improving symptoms of a lung abscess patient.

This project is to establish an annex clinic center under 5 floors with gross floor area of 3,000 Pyeong behind existing Chosun university Hospital main building with 600 beds. The goal of the design is connecting the new clinic center with the existing main building and completing a combined hospital that has synergy effects. Given the old condition of the hospital and characteristics of the ground, I tried to embody the image of Medical Pulse, which is very alive with strong pulse, and suggest vision of 21st century hospital. First, one main entrance as a combined hospital. For optimum access and functions, I used the entrance of existing building as the only main entrance of new combined hospital, rearrange the road in front of the main building and improve traffic system, and upgrade the image and function of combined main entrance by planning new atrium united robby that makes link to the main building easier. Second, section planning considering the optimum functions and convenience. I established 4 floors linking functionally with the existing building, minimized vertical traffic line, and enhanced convenience through barrier free environment, which is a horizontal traffic line without barriers, crucial to hospital. Third, combined zoning generating synergy effects. I linked sterilizing room with logistics center by operating room and service bridge, and arranged central treatment department horizontally, Also, by horizontally arranging cancer center and department of nuclear medicine close with PET and cyclotron center, I established identity of specialized departments.

Polycyclic aromatic hydrocarbons (PAHs) are persistent and commonly detected in marine ecosystem. They coexist with a various contaminants including heavy metals in real environment, but most studies have been still focused on single effects of these contaminants to aquatic organisms. In this study, the single and combined effects of benzy[a]pyrene (B[a]P) and HgCl₂ were investigated in the brackish water flea, Diaphanosoma celebensis. For combined effect study, three mixtures A (3:7), B (5:5), and C (7:3) of benzy[a]pyrene (B[a]P) and HgCl₂ were determined by 48 h - LC₅₀ values of single exposure. Combined effects of both chemicals were estimated by concentration addition (CA) model and independent action (IA) model. As results, 48 h - LC₅₀ values of benzy[a]pyrene (B[a]P) and HgCl₂ was 25.75 ㎍ l^-1 and 3.6 ㎍ l^-1, respectively. TU values of mixture A, B, and C were 1.06, 0.83, and 0.96, respectively, indicating additive effects of mixtures using CA model. This study will be helpful as basic data for understanding the combined effects of contaminants in marine environment.

We investigated the eradication rate and the adverse effects of combined treatment with western and oriental medication on Helicobacter pylori infected patients. We studied the eradication rate and the adverse effects of 1-week-triple therapy and 2-week-oriental medication(Banhasasimtang or Hyangsapeungeuysan) on Helicobacter pylori infected patients confirmed by urea breath test. Comparing 5 patients who took combined treatment with western and oriental medication, the results of this study showed that 4 patients got eradication effect of Helicobacter pylori with no influence on liver and kidney function. A patient had diarrhea and another patient had satiety after meals because of an adverse effect. Despite some possitive effect, the treatment did not make the Quality of Life improved. The findings of this study supports the adverse effects of combined treatment with western and oriental medication for the treatment of Helicobacter pylori infection.

The antimicrobial activity of the essential oil from Pelargonium graveolens and its effects when it was combined with current antibiotics against antibiotic-resistant strains of Streptococcus pneumoniae were evaluated. The minimal inhibitory concentrations (MICs) of the essential oil fraction and the main components of this plant were determined for two antibiotic-susceptible and two antibiotic-resistant strains of S. pneumoniae using broth microdilution tests. The combined effects of the oil with erythromycin, norfloxacin, or oxacillin were evaluated using a checkerboard microtitre assay. The combination of the oil fraction of P. graveolens, or its main component, together with the antibiotics tested significantly lowered the MICs of the antibiotics against all of the tested strains with fraction inhibiting concentration indices (FICs) ranging from 0.16 to 1.50. In particular, the activity of norfloxacin against all of the tested strains of S. pneumoniae was enhanced significantly by combination with citronellol. In conclusion, the combination of P. graveolens oil with antibiotics could be used to reduce the effective dose of antibiotic and to modulate the resistance of S. pneumoniae strains.

Disulfiram (DSF) is a marketed drug to treat patients with alcohol dependence by inhibiting aldehyde dehydrogenase. Over the last few decades, DSF has been shown to have anticancer effects through different mechanisms. Moreover, this effect can be elevated when used with copper (Cu). Subsequent studies have been conducted on various cancers, but few on lymphoma. This study investigated the anticancer effects of DSF on lymphoma and how this effect changed when treated with Cu. DSF synergistically decreased the metabolic activity of EL4 lymphoma cells when combined with Cu. At 1 µM of DSF alone, the metabolic activity of EL4 cells decreased by 49% compared to the control, whereas it decreased by 87% with a DSF + CuCl₂ treatment. Rhodamine 123 and 2',7'-dichlorofluorescein diacetate staining showed that DSF induced the reduction of the mitochondrial membrane potential and promoted the production of reactive oxygen species. In particular, the combined treatment of DSF + Cu induced cell death based on multiple assays, including annexin V-fluorescein isothiocyanate/propidium iodide staining. Overall, DSF has anticancer effects on lymphoma cells and exhibits synergistic effects when combined with Cu. This study provides some valuable information to broaden the use of DSF in clinics and basic research.

BACKGROUND/OBJECTIVES: Colorectal cancer (CRC) is the third most common cancer worldwide with a high recurrence rate. Oxaliplatin (OXA) resistance is one of the major reasons hindering CRC therapy. β-Carotene (BC) is a provitamin A and is known to have antioxidant and anticancer effects. However, the combined effect of OXA and BC has not been investigated. Therefore, this study investigated the anticancer effects and mechanism of the combination of OXA and BC on CRC. MATERIALS/METHODS: In the present study, the effects of the combination of OXA and BC on cell viability, cell cycle arrest, and cancer stemness were investigated using HCT116, HT29, OXA-resistant cells, and human CRC organoids. RESULTS: The combination of OXA and BC enhanced apoptosis, G₂/M phase cell cycle arrest, and inhibited cancer cell survival in human CRC resistant cells and CRC organoids without toxicity in normal organoids. Cancer stem cell marker expression and self-replicating capacity were suppressed by combined treatment with OXA and BC. Moreover, this combined treatment upregulated apoptosis and the stem cell-related JAK/STAT signaling pathway. CONCLUSIONS: Our results suggest a novel potential role of BC in reducing resistance to OXA, thereby enhances the anticancer effects of OXA. This enhancement is achieved through the regulation of cell cycle, apoptosis, and stemness in CRC.

The studies were conducted to investigate the combined effects of several combined preparation of crude drugs and mitomycin C(MMC). The combined effects on the proliferation of Molt-4 cells and activation of human lymphocytes were estimated by MTT colorimetric assays. The drugs itself enhanced the proliferation of Molt-4, but the inhibitory action of MMC was not affected by the combined treatment of the drugs and MMC. Among 9 kinds of the drugs, Sip Jeon Dae Bo Tang(SDT), Saeng Maek San(SMS) and Kwi Bi Tang(KBT) did not inhibit the action of MMC, but activated lymphocytes. When the mice were treated by MMC, the number of leukocytes was decreased significantly at the 1st day, but recovered at the 7th day. In the groups of MMC treated with SDT or KBT, the number of leukocytes was increased significantly than the group of MMC treated only at the 3rd day. The combined treatment of SDT, SMS and MMC retained the body weight of mice at the level of normal mice. The SDT, SMS and KBT did not change the number of plaque forming cells(PFC) and the proliferation of T cells. The combined treatment of SDT and MMC increased the number of PFC significantly than the MMC treated group. The combined treatment of SDT, SMS, KBT and MMC increased the T cell proliferation significantly than the MMC treated group. In conclusion, it is suggested that SDT, SMS and KBT can recover the side effects of MMC, such as weight loss, leukopenia and immunosuppression, without any intercalating the anti-proliferative action of MMC in vivo.
