  • BACKGROUND: The aim of this study was to evaluate the combined effect of low-level laser treatment (LLLT) and recombinant human bone morphological protein-2 (rhBMP-2) applied to hypoxic-cultured MC3T3-E1 osteoblastic cells and to determine possible signaling pathways underlying differentiation and mineralization of osteoblasts under hypoxia. METHODS: MC3T3-E1 cells were cultured under 1% oxygen tension for 72 h. Cell cultures were divided into four groups: normoxia control, low-level laser (LLL) alone, rhBMP-2 combined with LLLT, and rhBMP-2 under hypoxia. Laser irradiation was applied at 0, 24, and 48 h. Cells were treated with rhBMP-2 at 50 ng/mL. Alkaline phosphatase activity was measured at 3, 7, and 14 days to evaluate osteoblastic differentiation. Cell mineralization was determined with Alizarin red S staining at 7 and 14 days. Western blot assays were performed to evaluate whether p38/protein kinase D (PKD) signaling was involved. RESULTS: The results indicate that LLLT and rhBMP-2 synergistically increased alkaline phosphatase (ALP) activity and mineralization. Western blot analyses showed that expression of type I collagen, runt-related transcription factor 2 (RUNX2), and Osterix (Osx), increased and expression of hypoxia-inducible factor 1-alpha ($HIF-1{\alpha}$), decreased more in the LLLT and rhBMP-2 combined group than in the rhBMP-2 or LLL alone groups. Moreover, LLLT and rhBMP-2 stimulated p38 phosphorylation and rhBMP-2 and LLLT increased Prkd1 phosphorylation. CONCLUSION: Combined treatment with rhBMP-2 and LLL induced differentiation and mineralization of hypoxic-cultured MC3T3-E1 osteoblasts by activating p38/PKD signaling in vitro.

  • Objective: To investigate the electronic anti-nausea instrument (EANI) combined with hydrochloride palonosetron for prevention of chemotherapy-induced nausea and vomiting following highly emetogenic chemotherapy. Methods: Patients who received highly emetogenic chemotherapy were randomly assigned to a treatment group (60 patients) treated with EANI combined with hydrochloride palonosetron, and control group (also 60 patients) given only hydrochloride palonosetron. Chemotherapy related nausea and vomiting were observed and recorded in both groups of patients from the start till the end of chemotherapy. Results: Complete control rates of vomiting in treatment and control group were 40%, and 35%, respectively, without any statistical ly significant difference (p>0.05); however the response rates are 95.0%, 78.3%, respectively, with statistical difference (p<0.05). Complete control rates of nausea in treatment and control group were 36.7%, 30%, respectively, without statistical difference (p>0.05); but the response rates are 90.0%, 76.7%, respectively, with statistical difference (p<0.05). Conclusion: EANI combined with hydrochloride palonosetron for prevention of nausea and vomiting induced by chemotherapy could be more effective than hydrochloride palonosetron alone, and can be recommended for use in prevention and treatment of chemotherapy-induced nausea and vomiting following highly emetogenic chemotherapy.

  • Eighty of Sarcoma 180 bearing mice, averaging 30 gm of body weight, were divided into eight groups of animals receiving Saline as the control, Corynebacterium parvum, Tubercin-3 and Cyclophosphamide alone and Cyclophosphamide combined with C. parvum, with Tubercin-3 and with both C. parvum and Tubercin-3 and Tubercin-3 combined with C. parvum respectively. Treatment was initiated 4.8 hours after tumor implantation and repeated three times once a day. Doses were suspended or dissolved in 0.2 ml of Saline: 1.4 mg of C. parvum: 0.5 micrograms of Tubercin-3; and 2.7 mg of Cyclophosphamide either in alone or in combination. All the agents given were administered subcutaneously but Cyclophosphamide was given intraperitoneally. The observation on the general conditions of animal took place twice a day following the treatment until the time of death after tumor implantation was determined. Average survival days in each group were as follows: In Control, Saline (11.2 days), C. parvum (14.8 days), Tubercin-3 (16.7 days), Cyclophosphamide(18.7 days). In combination therapy, Cyclophosphamide with C. parvum(22.8 days) with Tubercin-3 (26.9 days). Cyclophosphamide with both C. parvum an Tubercin-3, however, was somewhat longer than in Cyclophosphamide alone but shorter than in combined with either one of C. parvum or Tubercin-3. Finally, in combination with immunotherapeutic agents, Tubercin-3 and C. parvum each other it (8.2 days) was shorter even than Control. Life span of host is, in generally, inversely related to the number of malignant cells and conclusively, the therapeutic potentiation was reflected to be extended survival in combined treatment of a chemotherapeutic Cyclophosphamide with either one of immunotherapeutics, Tubercin-3 or C. parvum. Tubercin-3 and C. parvum in combination, however, appeared to be antagonistic each other.

  • In order to investigate acute toxicity and bioconcentration of heavy metals for a freshwater fish, the fish used in this experiment was goldfish, Carassius auratus. Each ten goldfish was accommonidated in a water and was treated with different concentration of Pb and Cu compound. The 24 $hr-LC_{50}$ was obtained by plotting on the log-normal distribution graph. Furthermore, the combined effect of Pb and Cu was also investigated the fish was treated with Pb or Cu compound only, and Pb and Cu compound together, respectively. These results were summarized as follows: 1. The 24 $hr-LC_{50}'s$ of Pb and Cu were 7.48 mg/l and 0.666 mg/l, respectively. 2. When single or/and combined treatment with Pb(7.0 mg/l) or/and Cu(0.6 mg/l) to Carassius auratus for 24 hours were performed, there was significant difference between the single or/and the combined treatment in their bioaccumulated Cu concentrations. Cu concentrations in goldfish were higher in the combined treatment than in the single treatment. 3. When Carassius auratus was exposed to 0.748 mg/l (1/10 of 24 $hr-LC_{50}$) and 1.496 mg/l of Pb (1/5 of 24 $hr-LC_{50}$) for 7 days, the bioconcentration factors (BCF) were 79.14 and 100.11 for Pb, respectively. The BCF of Pb was obtained as a linearity according to the concentration and exposure time as follows log BCF=1.014 log $P\cdot T$+1.011 ($r^2$=0.9041) where, P: pollutant concentration(mg/l) T: exposure time(day) 4. When Carassius auratus was pxposed to 0.0666 mg/l (1/10 of 24 $hr-LC_{50}$) and 0.1332 mg/l of Cu (1/5 of 24 $hr-LC_{50}$) for 7 days, the bioconcentration factors (BCF) were 55.42 and 63.24 for Cu respectively. The BCF of Cu was obtained as a linearity according to the concentration and exposure time as follows log BCF=0.571 log $P\cdot T$+1.823 ($r^2$=0.8974) where, P: polutant concentration(mg/l) T: exposure time(day)

  • Extracts from Asian medicinal herbs are known to be successful therapeutic agents against cancer. In this study, the effects of three types of herbal extracts on anti-tumor growth were examined. Among the three types of herbal extracts, H9 showed stronger anti-tumor growth effects than H5 and H11 in vivo. To find the molecular mechanism by which H9 inhibited the proliferation of breast cancer cell lines, the levels of apoptotic markers were examined. Proapoptotic markers, including cleaved PARP and cleaved caspases 3 and 9, were increased, whereas the anti-apoptotic marker Bcl-2 was decreased by H9 treatment. Next, the combined effect of H9 with the chemotherapeutic drugs doxorubicin/cyclophosphamide (AC) on tumor growth was examined using 4T1-tumor-bearing mice. The combined treatment of H9 with AC did not show additive or synergetic anti-tumor growth effects. However, when tumor-bearing mice were co-treated with H9 and the targeted anti-tumor drug trastuzumab, a delay in tumor growth was observed. The combined treatment of H9 and trastuzumab caused an increase of natural killer (NK) cells and a decrease of myeloid-derived suppressor cells (MDSC). Taken together, H9 induces the apoptotic death of tumor cells while increasing anti-tumor immune activity through the enhancement of NK activity and diminishment of MDSC.

  • Objectives : This study was aimed to show the effect of electroacupuncture combined with magnetic acupuncture on abdominal obesity without patient dieting, exercise or use of herbal medication. Methods : Women over 85 cm in waist circumference were treated with electroacupuncture combined with magnetic acupuncture. Acupuncture points were located at the abdomen ($CV_{12}$, $CV_6$, $ST_{25}$, $ST_{21}$, $SP_{15}$, $SP_{14}$), extremities ($LI_4$, $LI_{11}$, $ST_{36}$, $ST_{44}$) and were stimulated 30 minutes with 2.1~3 Gaus, 500 Hz, tolerable strength. The Interference wave forms were by Whata 153 (Medi Lab, Korea). Two or three treatment sessions per week (five or ten sessions in total) were done. Before treatment, and after the last treatment, we measured waist circumference, hip circumference, waist hip ratio, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio, visceral fat area, free fat mass, body fat mass and skeletal muscle mass. We also measured the subcutaneous temperature of the abdomen($CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$, $CV_6$) by using digital infrared thermal imaging(DITI). Results : In this study, significant reductions were shown in waist circumference, hip circumference, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio and body fat mass. There were no significant differences in waist hip ratio, free fat mass or skeletal muscle mass. There were also significant increases of the subcutaneous temperature on $CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$. Conclusions : From the above results, electroacupuncture combined with magnetic acupuncture might be an effective treatment for abdominal obesity.

  • Objectives : Combined treatment (CT) of oriental herbal medicine and prescribed drugs is now being increasingly used among cancer patients around the world. However, in Korea, clinical information on the frequency, efficacy and safety of CT among cancer patients has not yet been thoroughly reported. This study aimed to identify the status and adverse effects of CT for the management of cancer patients. Methods : A questionnaire and medical record survey by oriental medical doctors or physicians were performed at two oriental medical hospitals and one general hospital. Of the initial 400 in-patients, 368 participated in this survey, representing a response rate of 92.0%. Results : Among cancer patients in oriental medical hospitals, the proportion of CT was 45.9%. In contrast, the proportion of CT in the general hospital was only 0.6%. The proportion of CT among breast cancer patients (20) and gastric cancer patients (35) were 85.0% and 51.4%, respectively. The proportion of CT among cancer patients was high in younger, female or married patients groups. 10 respondents (11.1%) among 90 cancer patients experienced several adverse effects including nausea, fatigue, etc. Conclusions : This study suggests that many more patients in oriental medical hospitals than general hospitals use combined treatment of oriental herbal medicine and prescribed drugs for management of cancer. Therefore, medical professionals should provide comprehensive and up-to-date clinical information about potential benefits and risks of CT to cancer patients in Korea.

  • Objective: This study was performed to report the effect of traditional Korean medicine as a treatment for laryngopharyngeal reflux (LPR) combined with depressive and anxiety disorder. Methods: We treated this patient with traditional Korean medicine and measured symptom severity using the reflux symptom index (RSI), Beck depression inventory (BDI), and Beck anxiety inventory (BAI). Results: After 3 weeks of treatment, most symptoms had decreased. The RSI score dropped from 21 to 8, BDI from 27 to 14, and BAI from 29 to 15. Conclusions: Traditional Korean medicine may be effective as a treatment for LPR combined with depressive and anxiety disorder, and a correlation may exist between LPR and psychological factors. However, more rigorous studies are required to identify exactly what treatment is most efficient for relieving LPR combined with depressive and anxiety disorder and whether LPR and psychological factors are clearly correlated.
