  • Aim and Background: The aim of the present study was to evaluate correlations between serum osteocalcin, osteoprotegerin and NTX (Cross-linked N-telopeptides of Type I Collagen) and urinary NTX in breast and lung cancer patients with bone metastases. These four markers are considered to have important roles in bone formation, resorption and metastases. Methods: Four markers were determined in the sera of 60 breast cancer and 21 lung cancer patients and healthy controls (n=30). Serum levels were studied using ELISA and EIA. Results: The median levels of serum osteoprotegerin (p<0.001) and osteocalcin (p=0.003) were higher in patients. Significant correlations were observed between the serum NTX-osteocalcin (r=0.431; p<0.001), serum NTX-osteoprotegerin (r=0.42; p=0.003) and serum NTX - urine NTX (r=0.255; p=0.022). Conclusion: We conclude that osteocalcin, osteoprotegerin and NTX are independent diagnostic tools. Due to the ease of urine collection, urine NTX may be applied routinely to allow early detection of bone metastases and indicate progression of the disease.

  • 알코올 의존의 음주 행동에 VTA에서 NA로 뻗어 있는 도파민 대뇌 보상 경로가 중요하다. 이러한 경로의 토파민 활성도가 $5-HT_3$계 신경에 의하여 조정되고 있으며, $5-HT_3$ 수용체 길항제인 ondansetron (OND)이 알코올리즘 환자에서 음주량을 감소시키고 금주률을 높인다는 보고가 있다. 이에 생쥐의 섭취량에 대하여 $5-HT_3$ 수용체 길항제인 ondansetron의 투여 효과와, 이러한 ondansetron 및 비 특이적 아편계 수용체 길항제인 naltrexone (NTX)과의 병합 투여 효과를 검증하는데 목적이 있다. 알코올 의존화 된 C57BL/6형 수컷 생쥐를 4군으로 나눈 뒤, 10일간 각 군에 vehicle, OND 0.01 mg/kg 단독, NTX 1.0 mg/kg 단독, 및 OND 0.01 mg/kg과 NTX 1 mg/kg 병합 투여하면서 2시간 알코올의 섭취량, 22시간 물 섭취량, 24시간 사료 섭취량 및 체중을 조사하였다. 본 연구의 결과로 2시간 알코올 섭취량의 10일간 변화에 대해 vehicle 투여 군과 나머지 3군의 약물 투여군과 repeated measure ANOVA를 이용하여 각각 비교하였을 때, vehicle 투여군과 NTX 단독 투여군간에 유의한 교차가 관찰되었으나 (p=0.042), OND 단독 투여군과 NTX과 OND 병합 투여군은 vehicle 투여군과 유의한 차이가 없었다. 일별 2시간 알코올 섭취량에 대하여 NTX 투여군과 vehicle 투여군의 군간 비교시 vehicle 투여군에 비하여 NTX 투여군에서 약물 투여 4일부터 10일까지 유의하게 감소하였다(4일 p=0.010; 6일 p=0.050; 8일 p=0.017; 10일 p=0.005). 그리고 NTX과 OND 병합 투여군과 vehicle 투여군의 양군을 비교하였을 때에는 2시간 알코올 섭취량이 4일과 10일에만 유의하게 감소하였다(4일 p=0.049; 10일 p=0.022). 그러나 22시간 물 섭취량, 24시간 사료 섭취량 및 체중의 10일간 변화에 대해 vehicle 투여군과 나머지 3 군의 약물 투여군과의 repeated measure ANOVA를 이용하여 각각 비교하였을 때, 모두 유의한 교차효과가 없었다. 이상의 결과는 생쥐의 섭취량에 대하여 OND의 투여 효과는 없었으며, OND과 NTX의 병합 투여시에는 NTX의 알코올의 섭취량 억제 효과가 감소되었다. 따라서 앞으로 $5-HT_3$ 신경계와 도파민 및 아편 신경계와의 상관관계에 대한 연구가 필요할 것으로 생각된다.

  • Objectives The object of this study was to observe the effects of Hyeongbangjihwhang-tang (HB; Soyangin prescription) on the 5/6 NTX induced CRF rats. Methods Each of Hyeongbangjihwhang-tang aqueous extracts 200mg/kg were orally administered once a day for 35 days from 4 weeks after 5/6 NTX surgery. Four groups, each of 8 rats per group were used in this study, were sham group, CRF group, ${\alpha}$-Tocoperol group and HB group. Changes on the left remnant kidney weights, serum BUN, creatinine levels, caspase-3, PARP immunoreactivities were observed to nephroprotective effects, and relative immunomodulatory effects were monitored based on the changes of lymphatic organ weights and splenic cytokine contents. In addition, the changes on the kidney MDA, GSH contents and SOD, CAT activities were also calculated for antioxidant effects, and the effects on the CRF related cachexia were demonstrated based on the changes of body and epididymal fat pad weights, serum TG, TC, LDL and HDL levels. Results and Conclusions 1) HB was significantly decreased the left remnant kidney weights, serum BUN, creatinine levels and caspase-3, PARP immunoreactivities. 2) HB was significantly increased lymphatic organ weights and splenic cytokine contents. 3) HB was significantly increased body and epididymal fat pad weights, and was significantly decreased serum TG, TC, LDL and HDL levels. 4) HB was significantly decreased MDA contents, and was significantly increased GSH contents and SOD, CAT activities. The results obtained in this study suggest that HB significantly retarded immunosuppressions and cachexia related to the 5/6 NTX induced CRF through modulations of oxidative defense systems. Especially HB showed the highest favorable effects more than those of ${\alpha}$-tocoperol.

  • To investigate the effects of dietary patterns on bone mineral density and its biochemical markers among Korean healthy college women for 2 years, 34 female college students were recruited through convenience sampling. Bone mineral density was measured using Dual Energy X-ray Absorptiometry (DEXA) twice at baseline and two years later. Osteocalcin and parathyroid hormone were measured in fasting serum and N-teleopeptides of type collagen (NTx) in urine. Dietary intake was assessed by 24-hour recall method 8 times with average 4-month interval. Dietary patterns with percent energy of each food group using cluster analysis were classified into two groups. The first cluster (n = 16) was characterized with high consumption of bread, snack, fast foods, beverage and considerable of rice so it was determined as 'Modified dietary pattern group'. The second cluster was characterized with high consumption of rice and kimchi so determined as 'Traditional dietary pattern group'. There were no significant difference of age, menarcheal age, body mass index but percent of body fat by pattern groups. The traditional group showed higher value of bone mineral density among lumber spine and all femur sites at baseline and 2 years later but it was not significant after adjusted for percent of body fat. Serum osteocalcin and urine NTx was higher among the traditional group at baseline than the modified group. There were similar proportions of carbohydrate:fat:protein between groups but significantly higher intake of protein, iron, vitamin A among the traditional group. In conclusion, there were two distinctive dietary patterns among Korean college women. There was difference of bone mineral density and its biochemical markers between two patterns. Further research would be necessary to explore the relationship between dietary patterns and health risks for larger-sized and various populations.

  • In this study, we investigated the therapeutic effects of a novel formulation of low-dose calcium and vitamin $D_3$ blended with Rehmannia glutinosa Libosch and Eleutherococcus senticosus Max (RE+), in postmenopausal women. The controls were given either a placebo or high dose calcium and vitamin $D_3$ (Ca + D). Bone mineral density (BMD) in the L2-3 lumber spines and femur regions was assessed, and serum osteocalcin, bone-specific alkaline phosphatase (BALP), and cross-linked N-telopeptide of type I collagen (NTx) were used as markers of osteoblast and osteoclast activity. Furthermore, all variables were measured before and after 6 and 12 months of treatment. The osteocalcin level was higher in the RE+ group, and BALP was almost the same in all groups. Serum NTx was significantly decreased in the RE+ group after 12 months (p<0.05). The NTx in the Ca + D and placebo groups showed no significant change. The decrease of femur BMD was further demonstrated in the placebo group, but significantly increased in the RE+ group after 6 and 12 months of treatment (p<0.05). There were significant differences in the percent changes of femur BMD between the placebo and RE+ groups (p<0.01) and Ca+D and RE+ groups (p<0.05). The decrease of spine BMD in the placebo group was inhibited both in the Ca + D and RE+ groups, however, there was significant difference only between the placebo and RE+ groups (p<0.05). These findings suggest that continuous oral therapy of the RE+ formulation reduces rapidly decreasing bone mineral density in postmenopausal women more effectively than high doses of calcium and vitamin $D_3$ alone by inhibiting osteoclastic activity. Therefore, it seems that the RE+ has its own antiosteoporotic effects. We suggest larger clinical studies to determine the most efficacious dosage and benefits of this novel treatment.

  • 본 연구는 20대부터 50대까지의 광주, 전남에 거주하는 180명의 건강한 성인 여성을 대상으로 진행되었다. 골대사지표로 골형성지표인 BAP와 OC, 골흡수지표인 NTx를 측정하였으며 골밀도로는 T-score를 이용하였다. 일반적 특징으로 영향 요인으로 연령, 음주, 신체 활동량, 골다공증에 대한 가족력, 폐경, 건강기능성식품 섭취 여부, BMI, 체지방률을 분석하였다. 연령에 따라 비교했을 때 BAP와 OC는 20대가 다른 나이군에 비해 낮았고 음주군은 비음주군에 비해 BAP가 더 높았다. 활동 정도에 따라서는 차이가 없었고 골다공증에 대한 가족력이 있는 군은 골다공증에 대한 가족력이 없는 군에 비해 BAP가 더 높았다. 또한 폐경군은 폐경전군에 비해 BAP가 더 높았으며 건강보조식품 섭취 여부에 따라서는 생화학적 골대사지표나 골밀도의 차이가 없었다. BMI에 따라서는 생화학적 골대사지표 및 골밀도의 차이가 없었지만 체지방률에 따라 분류했을 때는 정상군에 비해 비만군의 BAP가 더 높았고 골밀도는 더 낮았다. 이상의 결과로 보아 노령군, 음주, 골다공증에 대한 가족력, 폐경, 비만이 있는 경우 골형성지표가 증가하였고 특히 비만군에서 골밀도가 낮은 것을 확인하였다. 따라서 골대사지표로 보았을 때, 한국인 여성들은 골 건강을 위해서 나이가 증가함에 따라 음주 및 비만 관리가 중요함을 시사하였다.

  • Chemotherapy-induced peripheral neuropathy (CIPN) which is one of the common chemotherapy related toxicity poses a significant clinical challenge. Here we conducted a prospective pilot study to evaluate the efficacy of acupuncture on CIPN. Patients with CIPN were administered acupuncture procedure with continuation of previous conventional medication. Acupuncture procedures were conducted three times per week for 3 weeks. We assessed patients with Common Terminology Criteria for Adverse Events (CTCAE) v4.0, Visual Analog Scale (VAS), Functional Assessment of Cancer Therapy/Gynecologic Oncology Group Neurotoxicity (FACT/GOG-Ntx) at the time of baseline and every week after the acupuncture procedures. Total 5 patients were included and treated with acupuncture. CTCAE grades were the same of 2 in all patients. VAS mean value changed from 5.2 to 3.2, and FACT/GOG-Ntx total score that suggests the higher relates to better quality of life changed from 93.3 to 110 as mean value at the end of the 3rd week, though this index difference did not show any statistically significant difference. This pilot study suggests that acupuncture procedure may have a role for CIPN treatment. Launching a more larger and properly controlled study will be required to ascertain the efficacy of acupuncture.

  • BACKGROUND/OBJECTIVES: Soy isoflavones are expected to improve menopausal symptoms and osteoporosis in women. However, their efficacy is still inconclusive, and there was limited data for postmenopausal women in South Korea. We examined the effects of soy isoflavones on climacteric symptoms, bone biomarkers, and quality of life in Korean postmenopausal women. SUBJECTS/METHODS: A randomized, double-blind study design was used. Eighty-seven participants who had undergone natural menopause were randomly administered either 70 mg/day isoflavones (n = 43) or placebo (n = 41) for 12 weeks. We assessed the Kupperman index for climacteric symptoms and the menopause-specific quality of life (MENQOL) questionnaire for quality of the life. Biomarkers of bone metabolism were also measured in serum bone-specific alkaline phosphatase (BALP), osteocalcin (OC), N- and C-terminal cross-linking telopeptides of type Ι collagen (NTx, CTx), and urine-deoxypyridinolin (u-DPD). RESULTS: Scores of the Kupperman index were decreased in both the isoflavones group ($-7.0{\pm}15.8$, P = 0.0074) and placebo group ($-6.3{\pm}14.6$, P = 0.0064) during the intervention, but no significant difference was noted between the groups. Regarding the bone formation markers, the level of serum BALP increased by $6.3{\pm}4.1%$ (P = 0.004) and OC increased by $9.3{\pm}6.2%$ (P < 0.001), meanwhile those of the placebo were not changed. For the bone resorption markers, NTx, CTx, and u-DPD were not significantly different in either group. MENQOL was significant decreased in the isoflavone group ($-0.6{\pm}0.5$) and placebo group ($-0.6{\pm}0.4$), with a significant difference between groups (P = 0.0228). CONCLUSIONS: Our study suggests that 70 mg isoflavones supplement has beneficial effects on bone formation markers; however, it showed no benefit compared to the placebo on climacteric symptoms or quality of life.
