임선혜,정우진,채정우,강찬,윤휘열,Lim, Seon-Hye,Jung, Woo Jin,Chae, Jung-woo,Kang, Chan,Yun, Hwi-yeol 한국임상약학회 2020 한국임상약학회지 Vol.30 No.3
Background: The indication of denosumab for osteoporosis was expanded from second-line to first-line therapy in 2019. The aim of this study was to evaluate the efficacy of denosumab as both first- and second-line therapy in postmenopausal women with osteoporosis and osteopenia with risk factors by using the Fracture Risk Assessment Tool (FRAX). Methods: We conducted a medication use evaluation of denosumab in 98 patients who had been treated three or more times for osteoporosis or osteopenia at Chungnam National University Hospital from July 1<sup>st</sup>, 2017 to January 31<sup>st</sup>, 2020. Risk factors were identified using quantitative N-gram analyses of FRAX estimations. Patient information, including menopause status and results of bone mineral density tests (T-score), was obtained from electronic medical records. Results: Age, body mass index (BMI), prior medication use, and T-score were identified as risk factors and were included as variables in the evaluation of denosumab use. Since no significant differences were detected between groups, denosumab is likely effective regardless of age or BMI. In addition, no significant difference was detected in T-scores following denosumab treatment, between groups who took bisphosphonates and selective estrogen receptor modulators (SERMs) with denosumab as first-line therapy for postmenopausal osteoporosis. Denosumab may, therefore, be effective as second-line therapy. Conclusion: Efficacy of denosumab was evaluated in postmenopausal women with osteoporosis. Denosumab may be used as first- and second-line therapy regardless of age, BMI, and prior use of bisphosphonates and SERMs.

The purpose of this study was to target housewife membership golfers attending beginner’s class and was also to ask them to join a 15-week golf training course in indoor and outdoor golf range (forming two groups), so that it could find out which group had better golf shot performance. To achieve the goals, total 16 subjects were divided into indoor group and outdoor group (8 subjects respectively), but both groups were asked to join same golf training program at same place for 15 weeks. Summing up, it is found that outdoor exercise group shows higher improvement in all factors of driver shot than indoor exercise group, and the former also shows higher improvement in both distance and head speed than the latter. But it is found that both groups show lower impact after exercise. Hence, it is concluded that outdoor group shows higher improvement in overall golf shot performance than indoor group after training program.

파고지 추출물의 렛트에 대한 단회 경구 투여 독성 및 복귀돌연변이능 평가
김선아,임선혜,안지윤,김성란,하태열,Kim, Sun-A,Lim, Sun-Hye,Ahn, Ji-Yun,Kim, Sung-Ran,Ha, Tae-Youl 한국식품영양과학회 2007 한국식품영양과학회지 Vol.36 No.8
천연생리활성물질 소재로서 파고지 추출물의 안전성을 검증하기 위하여 렛트에 대한 단회 경구투여 독성 평가와 복귀돌연변이평가를 실시하였다. 파고지 에탄올 추출분말 2 g/kg, 5 mL를 암${\cdot}$수 각각 5마리씩 경구 투여한 후 14일 동안의 일반증상, 체중변화 및 부검시의 육안적 소견을 관찰한 결과, 사망례, 일반증상 및 체중변화는 관찰되지 않았고 부검결과에서도 특이할 만한 육안적 이상소견은 관찰되지 않아, 파고지 추출물은 $LD_{50}$값이 렛트 체중 kg당 2g 이상이며 단회 경구 투여에 대한 독성을 가지는 않는 것으로 평가되었다. 파고지 추출분말의 복귀돌연변이 유발성 여부는, 히스티딘 요구성 Salmonella Typhimurium TA98, TA100, TA1535, TA1537 균주 및 트립토판 요구성 Escherichia coli WP2uvrA(pKM101) 균주를 이용하여 S9 mix 첨가 여부에 따라 실험하였다. 용량설정시험 결과, S9 mix 첨가 여부에 관계없이 사용한 모든 시험균주에서 생육저해가 관찰되었다. 시험물질의 석출은 S9 mix 첨가 여부와 상관없이 사용한 모든 시험균주의 1,250, 2,500 및 5,000 ${\mu}g/plate$에서 관찰되었지만 콜로니 계수에는 영향이 없었다. 따라서, 본 시험의 용량은 S9 mix 미첨가 TA100, TA1537 균주 및 S9 mix 첨가 RA1535 균주의 경우에는 생육저해가 관찰된 625 ${\mu}g/plate$를, S9 mix 첨가 여부에 관계없이 TA98 균주 및 S9 mix 첨가TA100, TA1537, WP2uvrA(pKM101) 균주의 경우에는 생육저해가 관찰된 1,250 ${\mu}g/plate$를, S9 mix 미첨가의 TA1535 및 WP2uvrA(pKM101) 균주의 경우에는 2,500 ${\mu}g/plate$를 최고용량으로 하였고, 그 이하 공비 2로 최고용량을 포함한 5용량의 시험물질군과 음성대조군 및 양성대조군으로 하여 실험을 실시하였다. 그 결과, 모든 시험균주에서 시험물질에 의한 복귀변이 콜로니수는 S9 mix의 첨가 여부에 관계없이 용량의존적으로 증가되지 않았으며, 음성대조군과 비교하여 2배 이상의 증가를 보이지 않았다. 시험물질에 의한 균주의 생육저해는 S9 mix첨가 여부에 관계없이 사용한 모든 시험균주의 최고용량에서 관찰되었다. 시험물질의 석출은 S9 mix 첨가 여부에 관계없이 1,250 및 2,500 ${\mu}g/plate$에서 관찰되었지만 콜로니 계수에는 영향이 없는 것으로 나타났다. This study was performed to examine the toxicity of Psoralea corylifolia L. by the single-dose oral toxicity tests in rat and bacterial reverse mutation assay. In single-dose oral toxicity tests, 5 mL ethanol extract of P. corylifolia L. were directly injected into 10 rats (5 males and 5 females) at a dosage of 2 g/kg. Death practice was not detected during breeding periods (14 days), and $LD_{50}$ was calculated over 2 g/kg. No difference were observed with control group in the growth rate and histological observations. In bacterial reverse mutation assay, his(-) Salmonella Typhimurium TA98, TA100, TA1535, TA1537 and trp(-) Escherichia coli WP2uvrA (pKM101) were used for assessing the toxicity of ethanol extracts of P. corylifolia L.. No significant difference in formation of the colonies and no dose-dependent increase was observed regardless of the addition of S9 mix. The results showed that ethanol extracts of P. corylifolia L. did not have single-dose oral toxicity and mutagenic toxicity.
