Objectives : Seventh-day Adventists is well known to place a strong doctrinal emphasis on healthy life style that do not consume tobacco, alcohol or pork, and many adhere to a lacto-ovo-vegetarian lifestyle. This study aimed to investigate the difference of mortality between Korean Seventh-day Adventists and the general Korean population. Methods : We got 592 mortality data of Adventist cemetery in Seoul city and Kyunggi provincce of Korea, which contains information on causes of death for 2000-2004. Also we used mortality data of the general Korean population in Korea National Statistics Office for 2000-2004. Results : The mean age at death was 70.45 in Korean Adventists, 65.63 in the general Korean population. Higher neoplasm cause of death, such as of stomach, liver and breast, were observed in Korean Adventists than the general population. The death cause of injury, poisoning and external causes, and cerebrovascular disease were higher in the general population than Korean Adventists. The death cause of stomach cancer was lower in Korean Adventists who had above 10 years religious period than general population above age 50 years. In male, the death cause of lung cancer was lower in Korean Adventists than the general population. Conclusions : The results point to the importance of healthy life-style in Korean peoples, and indicate that lifestyle changes in the population might change the causes of death.

Purpose: We evaluated the results of surgical treatment for metastatic pathologic or impending pathologic fractures. Materials and Methods: From January 2004 to December 2007, 18 patients 19 cases were included. Male were 6 and female were 12. The mean age was 65.1. Mean follow up period was 15.2 months. Pathologic fractures were 14 and impending pathologic fractures were 5. MSTS score, periodic radiologic follow up and postoperative complications were evaluated. Results: The primary malignancies were 6 cases of multiple myeloma, 4 cases of renal cell carcinoma, 2 cases of cholangiocarcinoma, 2 cases of colon cancer, 2 cases of breast cancer and 2 cases of leiomyosarcoma. Metastatic lesions were 10 cases of femur, 4 cases of clavicle, 2 cases of humerus, 2 cases of tibia and 1 case of radius. Surgical options were curettage, cementation, internal fixation and arthroplasty. Mean MSTS score was 15.9. Postoperative complications were 1 case of infection, 1 case of local recurrence and 1 case of implant loosening. Ten patients were alive with disease, 8 patients died of disease. Conclusion: Surgical treatment of metastatic skeletal lesions allowed early ambulation and improving dexterity. It improved pain and emotional acceptance. Surgery is necessary for improving qualities of remaining lives.
The research has been aimed to investigate the effect of different sera including fetal bovine serum (FBS), male bovine serum (MS), female bovine serum (FS), and castrated-male bovine serum (C-MS) on cell proliferation, follicular maturation and ovulation in vitro. Established cell lines and primary cells were cultured in the culture media supplemented with different sera and cells proliferation was observed by cell counting and MTT assay. The results indicated that cell proliferation was significantly different for different serum source. Proliferation of bovine and human myogenic satellite cells was highest in MS. In contrast, proliferation of breast cancer cells and immune cells were the highest in FS and FBS, respectively. There was no difference in the rate of follicular growth, whereas the rate of ovulation was higher in FBS and C-MS. Finally, the wound healing effect and cell proliferation of 3T3-L1 cells showed that wound healing was fastest in FS and cell proliferation was higher in MS. These results suggest the importance of an optimal serum selection in the experiments involving cell culture system, and gender-specific Hanwoo sera may be used as a substitute to FBS.

Purpose: As well as patient survival, the restoration of postoperative function such as ambulation is important in limb salvage operations for treatment of malignant bone tumors involving the proximal femur. The authors analyzed clinical outcomes of limb salvage operations using tumor prostheses for metastatic or primary malignant bone tumors in the proximal femur. Materials and Methods: From February 2005 to January 2014, 20 cases (19 patients) with malignant bone tumor involving the proximal femur with pain or complicated pathologic fracture were treated with segmental resection and limb salvage operations with tumor prostheses. Mean age was 63.1 years (range 35-86). Fourteen patients were male and six ones were female. The mean follow-up period was 20 months (1-94 months). There were 15 cases of metastatic bone tumor, 4 cases of osteosarcoma, and 1 case of multiple myeloma. The primary tumors of the metastatic bone tumors included 4 lung cancers, 3 hepatocellular carcinomas, and 3 renal cell carcinomas. Other primary tumors were breast cancer, thyroid cancer, colon cancer, prostate cancer, and malignant spindle cell tumor, each in 1 case. Modular tumor prostheses were used in all cases; (Kotz's$^{(R)}$ Modular Tumor prosthesis (Howmedica, Rutherford, New Jersey) in 3 cases, MUTARS$^{(R)}$ proximal femur system (Implantcast, Munster, Germany) in 17 cases). Perioperative pain was assessed with Visual Analogue Scales (VAS). Postoperative functional outcome was assessed with Musculoskeletal Tumor Society (MSTS) grading system. Results: Out of 20 cases (19 patients), 11 cases (10 patients) survived at the last follow-up. Average postoperative survival of the 9 deceased patients was 10.1 months (1-38 months). VAS score improved from pre-operative average of 8.40 (5-10) to 1.35 (0-3) after operation. Average postoperative MSTS function score was 19.65 (65.50%, 7-28). The associated complications were 2 local recurrences, 3 hematomas, 3 infections, 2 scrotal swellings, and 1 dislocation. There was no case of periprosthetic fracture or loosening. Conclusion: Limb salvage operation with tumor prosthesis is an appropriate treatment for early pain reduction and functional restoration in malignant bone tumors in the proximal femur with pain an/or complicated pathologic fractures.
Parabens are alkyl esters of p-hydroxybenzoic acid, which are widely used in foods, cosmetics, and pharmaceutic products as preservatives. Absorbed parabens are metabolized fastly and excreted. Actually human body is exposed to complex mixture of parabens. Safety assessment at various toxicological end points revealed parabens have a little acute, subacute and chronic toxicities. Some reports have argued that as parabens have estrogenic activity, they are associated with the incidence of breast cancer through dermal absorption by cosmetics. There is an inference that antiandrogenic activity of parabens may give rise to a lesion of male reproductive system, but also there is an contrary. At cellular level, parabens may inhibit mitochondrial function of sperms and androgen production in testis, but also there is an contrary. Parabens seem to have little or no toxicity in embryonic development. Parabens can cause hemolysis, membrane permeability change in mitochondria and apoptosis, suggesting cellular toxicity of parabens. Parabens evoked endocrine disruption in several fish species and have toxic effect on small invertebrates and microbes. Therefore, the toxicity of parabens should be considered as a potentially toxic chemical in the freshwater environment. In conclusion, though parabens may be considered as a low toxic chemical, more definite data are required concerning the endocrine disrupting effect of parabens on human body and aquatic animals according to route and term of exposure as well as the residual concentration of parabens.

Objectives : The effects of Jaeumkanghwatang (JEKHT) co-administration on the pharmacokinetics of tamoxifen were observed after oral combination treatment of tamoxifen 50 mg/kg with JEKHT 100 mg/kg on JEKHT 6-day repeated oral pretreated rats with 8-day repeated co-administration to confirm the effects of JEKHT co-administration on the pharmacokinetics of tamoxifen. Methods : Six days after pretreatment of JEKHT 100 mg/kg, tamoxifen 50 mg/kg was co-administered with JEKHT 100 mg/kg, once a day for 8 days within 5 min. The blood were collected at 30 min before administration, 30 min, 1, 2, 3, 4, 6, 8 and 24 hrs after end of first and last 8th tamoxifen treatment, and plasma concentrations of tamoxifen were analyzed using LC-MS/MS methods. PK parameters of tamoxifen ($T_{max}$, $C_{max}$, AUC, $t_{1/2}$ and $MRT_{inf}$) were analysis as compared with tamoxifen single administered. Results : Six-day repeated oral pretreatment of JEKHT and 8-day repeated oral co-administration of tamoxifen within 5 min did not influenced on the plasma concentrations and pharmacokinetic parameters of tamoxifen, oral bioavailability, as compared with tamoxifen single treated rats, except for some negligible effects. Conclusions : It is concluded that JEKHT did not influenced on the plasma concentrations and pharmacokinetic parameters, the oral bioavailability of tamoxifen. Therefore, it is considered that co-administration of JEKHT and tamoxifen will be provide an effective novel treatment regimen on the comprehensive and integrative medicine for breast cancer patients, if they showed favorable synergic effects on the pharmacodynamics or reduce the tamoxifen treatment related toxicity and side effects in future studies.
Successful treatment of multi-loculated pleural effusion or thoracic empyema requires effective drainage and definitive diagnosis of causative organism. The purpose of this study was to assess the efficacy of the video-assisted thoracoscopic surgery in the management of thoracic empyema or multi-loculated pleural effusion after chest tube drainage treatment had failed. Material and Method: Between April 2000 and July 2002, 20 patients with thoracic empyema or multi-loculated pleural effusion that failed to chest tube drainage or other procedures who underwent an operation. All patients were assessed by chest-computed tomogram and underwent video assisted thoracoscopic drainage, debridement, biopsy and irrigation of pleural cavity. Result: In 18 cases (90%), underwent successful video-assisted thoracoscopic surgery. In 2 cases, decortications by mini-thoracotomy were necessary. The ratio of sex was 4 : 1 (16 male: 4 female), mean age was 48.9 years old (range, 17∼72 years), mean duration of postoperative chest tube placement was 8.2 days (range, 4∼22 days), mean postoperative hospital stay was 15.2 days (range, 7∼33 days). Causative disease was tuberculosis, pneumonia, trauma and metastatic breast cancer, There were no major postoperative complications. Symptoms improved in all patients and were discharged with OPD follow up. Conclusion: In an early organizing phase of empyema or multi loculated pleural effusion, video-assisted thoracoscopic drainage and debridement are safe and suitable treatment.
Objectives: The effects of Gamiondam-tang (GMODT) co-administration within 5min on the pharmacokinetics (PK) of tamoxifen were observed as a process of the comprehensive and integrative medicine, combination therapy of tamoxifen with GMODT to achieve synergic pharmacodynamics and reduce toxicity on the breast cancer. Methods: After 50mg/kg of tamoxifen treatment, GMODT 100mg/kg was administered within 5min. The plasma were collected at 30 min before administration, 30 min, 1, 2, 3, 4, 6, 8 and 24 hrs after end of GMODT treatment, and plasma concentrations of tamoxifen were analyzed using LC-MS/MS methods. PK parameters of tamoxifen (Tmax, Cmax, AUC, $t_{1/2}$ and $MRT_{inf}$) were analysis as compared with tamoxifen single administered rats using noncompartmental pharmacokinetics data analyzer programs. Results: Co-administration with GMODT induced increased trends of plasma tamoxifen concentrations to 1hr after end of administration, and then showed decreased trends of plasma tamoxifen concentrations, and especially significant (p<0.05) increases of plasma tamoxifen concentrations were demonstrated at 0.5hr after end of co-administration with GMODT and also related significant (p<0.05) decreases of $AUC_{0-inf}$ and $MRT_{inf}$ as compared with tamoxifen single formula treated rats, at dosage levels of tamoxifen 10 mg/kg and GMODT 100 mg/kg within 5 min, in this experiment. Conclusion: Based on the results of the present study, it is considered that single co-administration GMODT within 5min significantly inhibited the oral bioavailability of tamoxifen through variable influences on the absorption and excretion of tamoxifen, can be influenced on the toxicity or pharmacodynamic of tamoxifen.

Listeria monocytogenes infection was considered a rather rare disease and occurs mostly either in newborn babies or in young children. However, there has been increasing reports of this infection in elderly person with various underlying disease. Recently we have experienced two cases of Listeria meningitis; one in a 4-year-old male with an acute lymphoblastic leukemia, and the other in a 43-year-old female with a breast cancer. Both were on various chemotherapeutic agents for their primary diseases when the organism, L. monocytogenes was found in their celebospinal fluid(CSF). The degree of CSF pleocytosis were quite different by cases. The former case showed a marked increase, $3,350/mm^3$, and the latter slight, $410/mm^3$, Both showed a slight decrease of CSF glucose ranging 39 to 43mg/100ml. It seems that a routine CSF analysis bears a limitted value in the diagnosis or Listeria meningitis. A direct smear of CSF with Gram's stain revealed gram-positive bacilli in one case, but none in the other. Bacterial culture of CSF yielded plenty colonies in one case, but a few in the other. It seems that isolation of L. monocytogenes must not be considered very easy, and a negative direct smear does not necessarily mean a negative culture. The two isolates we obtained showed the typical cultural and biochemical characteristics of L. monocytogenes and were found to belong to serotypes 1b and 4b. It was our experience that the identification of this organism was not very much matter because of its distinct characteristics, but the most important matter was how to think of the possibility of this organism at the begining. The two isolates were both susceptible to cephalothin, chloramphenicol, erythromycin, tetracycline and gentamicin; intermediate to ampicillin, penicillin and kanamycin; and resistant to cloxacillin.
Objectives : In our previous study, single co-administration GMODT within 5 min significantly inhibited the oral bioavailability of tamoxifen through variable influences on the absorption and excretion of tamoxifen. Therefore, the object of this study was to elucidate the possible effects on the pharmacokinetics of tamoxifen after single oral co-administration of GMODT with 2.5 hr-intervals. Methods : After 50 mg/kg of tamoxifen treatment, GMODT 100 mg/kg was administered with 2.5 hr-intervals. The plasma were collected at 30 min before administration, 30 min, 1, 2, 3, 4, 6, 8 and 24 hrs after end of GMODT treatment, and plasma concentrations of tamoxifen were analyzed using LC-MS/MS methods. PK parameters of tamoxifen (Tmax, Cmax, AUC, $t_{1/2}$ and $MRT_{inf}$) were analysis as compared with tamoxifen single administered rats. Results : Two-half hr-interval co-administration with GMODT induced variable changes on the plasma tamoxifen concentrations as compared with tamoxifen single treated rats, and especially significant (p<0.05) increases of plasma tamoxifen concentrations were demonstrated at 0.5 (199.61%) and 1 hr (101.06%) after end of co-administration with GMODT, and also related significant (p<0.05) decreases of $t_{1/2}$ (-39.54%) and $MRT_{inf}$ (-43.94%) as compared with tamoxifen single formula treated rats, at dosage levels of tamoxifen 50 mg/kg and GMODT 100 mg/kg with 2.5 hr-intervals, in this experiment. Conclusions : According to the results, GMODT critically decreased on the oral bioavailability of tamoxifen through variable influences on the absorption and excretion of tamoxifen. Hence, the co-administration of GMODT and tamoxifen should be avoided in the comprehensive and integrative medicine, combination therapy of tamoxifen with GMODT on the breast cancer.
