Two farmed young ostrich chicks were applied to pathology laboratory at Chungnam National University. Grossly, one ostrich showed rotated tibiotarsus, the other showed rolled toes. Case 1 ostrich was hypertrophy of fibualis longus and tibial cranialis tendon and gastrocnemius tendon in crus, inflammation of flexor digitorum longus. In histopathological views, myocytes of fiburalis longus were showed hypertrophy and hyperplasia. It is not found any specific feature in X-ray of the case 2 ostrich. Limb deformities were detected frequently in farmed ostrich chicks in 2- to 3 weeks old. Limb deformities were an important cause of mortality in farmed ostrich chicks during the first 10weeks after hatch. Cause of limb deformities were considered a nutrition problem.

Objectives : As the elderly population is continuing to increase, psychiatric diseases of the elderly are becoming an important social issue. This study looks into the demographical and clinical features of the elderly patients diagnosed with bipolar disorder in a University hospital. Methods : The study subjects include patients admissioned in the closed wards of Soonchunhyang Seoul hospital and Cheonan hospital from March, 2000 to February, 2005 who met the DSM-IV-TR criteria for bipolar disorder at the time of discharge. A total of 146 patients (76 men, 70 women) medical records were studied retrospectively. Subjects older than the age of 50 at time of admission were grouped as the old age group, whereas those who were younger than 50 as the young age group. Also among the old age group, those who had the first onset of episode under the age of 50 were grouped as the early onset group, whereas those who had the first onset after the age 50 were grouped as the late onset group. Results : The number of bipolar disorder patients in the young age group and old age group were 73 and 73 respectively. The number of early onset group and late onset group were 46 and 23 respectively. The old age group had a relatively higher incidence of bipolar II disorder than the young age group. Also in the old age group there was a higher incidence of hypomanic or depressive episode rather than manic episode compared to the young age group. And in the old age group psychotic symptoms were less common and the mean admission length shorter than the young age group. Additionally in the old age group treatment with Lithium monotherapy or with no mood stabilizers at all were relatively common. Among the old age group, late onset group had a higher rate of bipolar II disorder than the early onset group. Conclusion : This study shows differences in the demographical and clinical features among different age groups. But additional research would be required to determine whether the bipolar disorders in the elderly or late onset group are actually a different type of disorder from those of the young.

양해조(Haejo Yang),박현정(Hyunjeong Park),윤형열(Hyeongyeol Yun),김영준(Young-Jun Kim),신영재(Youngjae Shin) 한국식품과학회 2021 한국식품과학회지 Vol.53 No.2

국내에서 재배한 A. melanocarpa 잎의 성숙도에 따른 이화학적 특성 변화, 항산화 물질 조성 변화 및 항산화 능력과 같은 기능적 특성을 분석하여, 아로니아 잎의 성숙도별 이용 가능성을 확인하였다. A. melanocarpa 3품종의 잎의 폴리페놀, 플라보노이드, 페놀화합물 함량은 성숙이 진행될수록 감소하였고, 항산화물질과 상관관계가 높은 ABTS 라디컬 소거능 및 DPPH 라디컬 소거능 역시 감소하는 경향을 보였다. 현재, 블루베리는 잎과 열매 모두 식품원료로 등록되어 있으나, 아로니아의 경우는 식품의약안전처에서 고시한 식품원료목록 상 열매 부위만 등록되어 있는 실정이다. 아로니아 잎에는 chlorogenic acid와 catechol이 다량 함유되어 있고, 아로니아 잎의 항산화 능력은 기타 베리류와 비교하였을 때, 상당히 높은 수준인 것으로 확인된 바와 같이, 아로니아 잎은 향후 가공 식품 이외에 다양한 분야로의 활용 가능성이 충분할 것으로 판단된다. In this study, the leaves of aronia (Aronia melanocarpa) across different stages of maturity were collected and their chlorophyll content, antioxidant content, and activity were analyzed. The leaves of the selected aronia cultivars (‘Viking’, ‘McKenzie’, and ‘Kingstar K1’) were harvested in June (young-stage leaf) and in August (old-stage leaf). The antioxidant content and activity of all three aronia cultivar leaves were significantly higher in the young-stage leaves than in the old-stage leaves. The main polyphenols in aronia leaves were catechol and chlorogenic acid, which tended to decrease as maturation progressed. As a result, the young-stage aronia leaves contained more abundant flavonoids, phenolic compounds, and polyphenols with higher antioxidant activity than those in the old-stage leaves. Overall, our findings indicate that aronia leaves contain potential bioactive compounds that could be used to develop functional food ingredients.

Granulocyte colony-stimulating factor(G-CSF) have been shown to hasten the recovery of neutropenia following anti-cancer chemotherapy. There are controversial opinions on the use of G-CSF in acute myelogenous leukemia(AML) because clonogenic studies have shown that G-CSF stimulates leukemic colonies as well as granulocyte colonies. In this study, we evaluated the effectiveness and safety of recombinant human G-CSF after induction chemotherapy with DAV regimen(Ara-C 100mg/㎡ day 1-8, Doxorubicin 45mg/㎡ day 3-5, VP-16 100mg/㎡ day 6-8) in 9 patients with AML. G-CSF therapy(200 ㎍/㎡/day) was begun 2 days after the end of chemotherapy and continued for 10 days. 17 AML patients who recieved the same chemotherapy before the onset of this study were used as historical control. G-CSF shortened the duration of granulocytopenia (less than 500/㎣) significantly (13 vs 23 days, p<0.001), but it had no effect on platelet recovery. Although the incidence of febrile episodes was almost the same, the duration of febrile episodes was shorter in the group treated with G-CSF( 5 vs 12 days, p=0.03). There was no evidence that G-CSF accelerated the regrowth of leukemic cells and the complete remission rates between the 2 groups were not different. These results show that G-CSF accelerates the recovery of granulocytopenia and shortens the febrile days after chemotherpy in patients with AML, without affecting the regrowth of leukemic cells.

Uterus didelphys with unilateral obstructed hemivagina and ipsilateral renal agenesis usually presents after menarch with progressive abdominal pain during menses secondary to hematocolpos, and indeed a very rare congenital anomaly due to Mullerian duct malformation. An accurate and prompt diagnosis is of importance to permit treatment and to assure the future fertility of the patient. Pelvic ultrasound, physical examination and pelvic MRI established a diagnosis of hematometracolpos secondary to uterus didelphys with unilateral imperforate hemivagina. An incision in the vaginal septum allowed drainage of the hematocolpos, providing relief of the patients symptoms. We report two case of uterus didelphys with obstructed hemivagina with brief review of the literature.

Recently the development of CNC machine tools seems to bring about progressional high speed, precision, and automation in cutting processing, but is unlikely to avoid the generation of burr arising from plastic deformation, which may result in deterioration of improvement in the precision and productivity of products. This study conducted a comparative analysis of the sizes of burrs via two-dimensional low speed cutting experiments under varied different cutting conditions by taking as its materials of cutting A6061, A2014, STS304 and SM40C commonly used for precision machine paets, motor cars, aircrafts, and so on. When the depths of burrs increase, the size of the burrs are inclined to increase linearly at their final stage rather than the lateral sizes of the burrs. When cutting becomes fast in speed, the lateral sizes of burrs appear consistent, but from a relative perspective the sizes of the final burrs tend to be remarkably increased. An increase in the angle of inclination of α is seen as effective in reducing the thickness of burrs, and burrs were more decreased in size on coating tools rather than in uncoating tools.
