전영진,박수병,손우성 대한치과교정학회 1997 대한치과교정학회지 Vol.27 No.2
본 연구는 골격성 III급 부정교합자에서 상하악절치의 치성보상 양상과 골격형태 사이의 상관관계를 규명하기 위해 시행되었다. 정상교합자 59명, 미약한 골격성 III급 부정교합자 91명 그리고 심한 골격성 III급 부정교합자 58명을 연구대상으로 선정하였으며 특히 미약한 골격성 III급 부정교합자는 전치부 반대교합의 유무에 따라 반대교합이 없는 군과 반대교합군으로 세분하여 연구하였다. 측모두부방사선규격사진을 15개의 골격형태 계측항목과 16개의 상하악절치 경사도 및 위치 계측항목으로 분석한 뒤 통계 처리하여 다음과 같은 결과를 얻었다. 1. 각 군의 상하악 전치부 치성보상 양상을 보면 II-B군에 비해 II-A군과 III군의 상악 중절치는 순측경사 되어 있으며 II-A군이 III군 보다 크게 순측경사 되어 있었다. 하악절치는 II-A군과 II-B군에 비해 III군이 설측경사 되었으며 II-A군과 II-B군의 차이는 없었다. 2. II-A군과 II-B군 사이의 수직적인 골격형태 차이는 크지 않았고 하악절치 보다는 상악절치 위치 및 경사도에서 큰 차이를 보였다. 3. II-A군의 하악절치와 II-B군의 상악절치 계측항목이 골격형태와 상관성이 높았으며 특히 하악절치 계측항목중에서는 ∠IMPA, ∠FMIA, 상악절치 계측항목중에서는 ∠U1-FH, ∠U1-SN이 높은 상관성을 보였다. 4. 하악절치 계측항목중 ∠IMPA, ∠FMIA는 모든 군에서 골격형태와 높은 상관성을 보였다. 상악절치 계측항목중에서는 ∠U1-SN, ∠U1-FH, U1-facial plane(mm)이 다른 계측 항목에 비해 상관성이 높았다. This investigation was designed to analyze the degree of dental compensation according to horizontal components of craniofacial skeleton and to investigate correlation between dental compensation and craniofacial pattern in skeletal class III malocclusion. The material selected for this study consisted of standard lateral cephalogram of 59 subjects in normal occlusion group, 91 subjects in mild skeletal class III malocclusion group and 58 subjects in severe skeletal class III malocclusion group, The mild skeletal class III malocclusion group was divided into two groups, one was class III malocclusion without anterior crossbite group and the other was class III malocclusion with anterior crossbite group. 1. Mild skeletal class III malocclusion without anterior crossbite group showed the most labial inclination of upper incisors, followed by severe skeletal class III malocclusion group and mild skeletal class III malocclusion with anterior crossbite group, the latter showing the least. The amount of lingual inclination of lower incisors was the largest in severe skeletal class III malocclusion group, and there was no statistically significant difference between mild skeletal class III malocclusion without anterior crossbite group and mild skeletal class III malocclusion with anterior crossbite group. 2. There were little differences in vertical skeletal structure between mild skeletal class III malocclusion without anterior crossbite group and mild skeletal class III malocclusion with anterior crossbite group, they showed statistically significant differences in the upper incisors measurements. 3. The measurements of lower incisors in mild skeletal class III malocclusion without anterior crossbite group and upper incisors in mild skeletal class III maloclusion with anterior crossbite group represented a high correlation with skeletal structure. Especially, ∠IMPA and ∠FMIA of lower incisor measurements, and ∠U1-FH, ∠U1-SN of upper incisor measurements showed high correlation with skeletal structure in each group. 4. ∠IMPA and ∠FMIA of lower incisor measurements showed high correlation with skeletal structure in all groups. ∠U1-FH, ∠U1-SN and U1-facial plane(mm) of upper incisor measurements represented higher correlation with skeletal structure than any other upper incisor measurements.

The purpose of this study was to produce regression equation of VO₂max prediction appropriated to elementary, middle and high school male students, and to eveluate the validity of their predictions. The predictions of VO₂max (ℓ/min, ml/㎏/min and ml/FFW/min) were obtained by multiple regression procedures from a sample of 53 students, aged 7∼17 years. The prediction for VO₂max were obtained from the subjects’age, height, weight,% fat and fat-free weight. From the result of multiple regression for VO₂max, the following equations were obtained. ------------------------------------------------------------------------------- Inde.

The multiple correlations for the prediction in ml/㎏/min (No.4,5,6) were quite different (R=0.45, 0.41, 0.29), but the relative errors of estimation, ±9.9%, ±10.1% and ±10.6% respectively, were quite similar. The multiple correlations and relative errors of estimate for the predictions in ml/FFW/min (No.7,8,9) were quite similar (R=0.68, 0.62, 0.45; CV= ±9.3%, ±10.2%, ±11.6%). The validity of prediction equations was tested from the validity group (7∼17 years, 19boys). It is 0.92∼0.94 for equation 1∼3, 0.50∼0.65 for equation 4∼6, and 0.59∼0.64 for equation 7∼9. Their prediction equations were quite stable, % errors approximately -0.8∼-3.2%. It indicated that the predictive equations in this study provide more reliable than the Astrand-Ryhming nomogram and that reasonably and accurate of VO₂max for the male students may be obtained from their age, height, weight, %fat and fat-free weight.

Clinical effects of rhG-CSF were investigated in 17 patients receiving chemotherapy for non-Hodgkin's lymphoma. Patients were given G-CSF 2㎍/㎏/day after 2nd cycle chemotherapy for least 14 consecutive days, and clinical and laboratory results were compared to results of the first cycle. Treatment with G-CSF resulted in increase of mean WBC count(952.9±152.2㎜³vs 1882.4±350.4/㎜³) and neutrophil count(212.9±53.0/㎜³vs 841.5±238.0/㎜³), reduced the duration of leukocytopenic days(12.4±1.3 days vs 5.5±1.0 days, WBC count less than 4000/㎜³) and neutropenic days(4.5±0.9 days vs 2.3±0.7 days, neutrophil count less than 500/㎜³), and reduced the duration of neutropenic fever(5.8±1.1 days vs 0.9±0.5 days). The side effects of G-CSF were not so significant. These results demonstrated that G-CSF is safe and useful for the treatment of neutropenia induced by anticancer chemotherapy of non-Hodgkin's lymphoma and reducing the incidence of febrile periods and duration of antibiotic administration.

Hematopoietic stem cell transplantation (HSCT) can cause various complications involving lung, liver intestine and other organs, Chemotherapy, radiation therapy, and graft-versus-host disease (GVHD) may injure the cells in the intestinal mucosa of HSCT recipients. Pneumatosis cystoides intestinalis (PI) is a condition that presence of air in the bowel wall is demonstrated by radiologic or pathologic tests, It is one of the infrequent complications after HSCT and is associated with several medical and surgical conditions. However its pathogenesis and definite etiologic factors are still unknown. Here, we present a case of PI in a HSCT recipient, who was diagnosed of bronchiolitis obliterance accompanied with chronic GVHD and pulmonary disease caused by Mycobacterium abscessus.

<P><B>Abstract</B></P> <P>We propose silicone implants capable of the local, controlled release of a glucocorticoid drug, triamcinolone acetonide (TA), for the prevention of fibrosis. The shells of these silicone implants were coated with two different loading amounts of TA, which could release the drug in a sustained manner for 12 weeks. The drug-loaded implants were inserted into the subcutaneous space in living rats, and the tissues were biopsied at scheduled times during 12 weeks. For the drug-coated implants, the capsule thickness and collagen density decreased compared with those of the non-coated implant. Because of the effect of TA, inflammation and the expression of pro-inflammatory cytokines were downregulated, thereby decreasing the number of monocytes during acute inflammation. This effect in turn decreased the number of macrophages at the later stage of inflammation, leading to the expression of less TGF-β and consequently fewer fibroblasts and myofibroblasts. Our findings also revealed that with an appropriate dose control, skin and muscle atrophy, major side effects of TA, could be avoided while still effectively reducing fibrosis. Therefore, we conclude that the local, sustained release of an appropriate dose of a glucocorticoid drug can be a promising strategy for safely preventing fibrosis around silicone implants.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
