의약품등의 배아(태자) 독성물질에 의해서 유도될 수 있는 태자체중의 감소와 골화지연은 실험동물을 이용한 생식독성 시험에 있어서 자궁내 발육지연 (intrautering growth retardation)으로 평가된다. 태자체중은 측정이 매우 용이한 변수에 속하지만 골화지연의 평가에는 유해인자 (noxa) 의 작용시 기형이 유발되지 않는 골격부위가 가장 적합한데, 어느 골격부위가 발육지연 효과의 평가를 위하여 가장 적합한지를 알아내기 위해서는 태자체중과 골화의 상관성 조사가 필수적이다. 연구결과 골격형성은 골격부위에 따라 큰 차이를 보였는데, 크게는 거의 골화가 종료된 부위 (예: 흉골) 와 골화가 진행증인 부위 (예: 천미추) 로 구분되었고 주요 골격부위의 골화와 태자체중의 관계를 조사한 바, 골격부위에 따라서 상이한 상관관계를 나타내었다. 그런데 본 연구에서 나타난 바로는 ICR 마우스에 있어서 천미추의 골화짐 수가 태자제중과 가장 높은 상관성을 나타내었다. 또한 천미추의 변이계수는 타 골격부위에 비해서 그다지 높지 않았다. 따라서 ICR 마우스를 이용한 생식독성시험에 있어서 천미추의 골화 진행도는 의약품등에 의해 유도될 수 있는 발육지연 효과의 평가를 위한 가장 적합한 지표라고 판단된다.

Hypsizygus marmoreus (white cultivar), also called white beech mushrooms, are edible mushrooms commercially cultivated in Korea and Japan. This study was carried out to evaluate the antioxidant properties of H. marmoreus. H. marmoreus fruit bodies were divided into pileus and stipe. The pileus and stipe were extracted into water and 80% ethanol and their antioxidant activities were analyzed. The total polyphenol content was highest in the water extract (pileus 1137.39±0.38 mg of GAE (gallic acid equivalents)/100 g, stipe 700.86±0.06 mg of GAE/100 g) compared to the ethanol extract (pileus 923.47±0.18 mg of GAE/ 100 g, stipe 324.05±0.03 mg of GAE/100 g). Ethanol extracts from pileus showed better scavenging ability on DPPH (47.32±0.23% at 10 mg/ml) and ABTS (57.33±0.10% at 10 mg/ml) than the stipe and water extract groups. Water extract from pileus were more effective in reducing power and ORAC (oxygen radical absorbance capacity) value than stipe and ethanol extract. The toxicity of water and ethanol extracts was investigated using WST-1 (Water Soluble Tetrazolium salt) assay on the mouse macrophage cell line RAW 264.7. Overall, total polyphenol content and antioxidant activities of extracts from H. marmoreus increased in a dose dependent manner while pileus was showed better total polyphenol content and antioxidant activities than stipe.

Purpose: This study was designed to evaluate the effects on bone mineral density (BMD) and related factors according to the distance from the radiation field at different sites. This study was conducted on patients with uterine cervical cancer who received pelvic radiotherapy. Materials and Methods: We selected 96 patients with cervical cancer who underwent determination of BMD from November 2002 to December 2006 after pelvic radiotherapy at Kosin University Gospel Hospital. The T-score and Z-score for the first lumbar spine (L1), fourth lumbar spine (L4) and femur neck (F) were analyzed to determine the difference in BMD among the sites by the use of ANOVA and the post-hoc test. The study subjects were evaluated for age, body weight, body mass index (BMI), post-radiotherapy follow-up duration, intracavitary radiotherapy (ICR) and hormonal replacement therapy (HRT). Association between the characteristics of the study subjects and T-score for each site was evaluated by the use of Pearson's correlation and multiple regression analysis. Results: The average T-score for all ages was -1.94 for the L1, -0.42 for the L4 and -0.53 for the F. The average Z-score for all ages was -1.11 for the L1, -0.40 for the L4 and -0.48 for the F. The T-score and Z-score for the L4 and F were significantly different from the scores for the L1 (p<0.05). There was no significant difference between the L4 and F. Results for patients younger than 60 years were the same as for all ages. Age and ICR were negatively correlated and body weight and HRT were positively correlated with the T-score for all sites (p<0.05). BMI was positively correlated with the T-score for the L4 and F (p<0.05). Based on the use of multiple regression analysis, age was negatively associated with the T-score for the L1 and F and was positively correlated for the L4 (p<0.05). Body weight was positively associated with the T-score for all sites (p<0.05). ICR was negatively associated with the T-score for the L1 (p<0.05). HRT was positively associated with the T-score for the L4 and F (p<0.05). Conclusion: The T-score and Z-score for the L4 and F were significantly higher than the scores for the L1, a finding in contrast to some previous studies on normal women. It was thought that radiation could partly influence BMD because of a higher T-score and Z-score for sites around the radiotherapy field. We suggest that a further long-term study is necessary to determine the clinical significance of these findings, which will influence the diagnosis of osteoporosis based on BMD in patients with cervical cancer who have received radiotherapy.
