  • Purpose: The purpose of this study is to evaluate the relationship between trochlear medial facet osteophyte (TMFO) and elbow flexion in the elbow joints without trauma history. Materials and Methods: Twenty five patients, who underwent computed tomography without elbow trauma history, were reviewed. Patients were checked for osteophyte or loose bodies in the coronoid and olecranon sides. The height and length of TMFO were measured. Results: The average elbow flexion contracture was $18.6^{\circ}$, and further flexion was $112.1^{\circ}$. The TMFO height and length was 2.2 mm and 4.7 mm, respectively. The average elbow further flexion was $105.1^{\circ}$ in the coronoid block group (n=14) and $119.1^{\circ}$ (p=0.011) in the coronoid free group (n=11). The relationship between further elbow flexion and TMFO was significant with a partial correlation coefficient of 0.687(p<0.000) in the TMFO length. Conclusion: Elbow joints with longer TMFO length decrease further flexion.

  • For effective production of interspecific hybrids of Lilium and valuable new cultivars, we used Lilium Asiatic hybrid 'Tiny Ghost' as the female parent, and Oriental group, and Longiflorum group and Martagon as the male parents. Percentage pollen germination in Oriental hybrid 'Sorbonne' was the highest with 64%. As results of using normal style pollination and cut style pollination methods, all seed sets were formed in normal style pollinated treatment, except in 'Aktiva'. Pollen germination percent of Longiflorum hybrid 'Norina' was higher than that 'Gelria'. However, all crossings using 'Norina' failed to set seeds. Corresponding fertilization ratio was different from genetic compatibility, even in the same group. From the crossing using 'Aktiva' as the male parent one bulb was obtained derived from one embryo sac. And using 'Sorbonne' as the male parent, one plantlet was obtained after four ovule cultures. Crossing using 'Gelria' as the male parent five embryos, 15 embryo sacs, and seven ovules per one ovary were obtained. Among them, 18 plantlets germinated, with the germination percent of 66.7%. Crossings using L. hansonii, Martagon group, as the male parent resulted in 40% germination from five ovules.

  • An Asiatic lily cultivar 'Apricot King' was bred in 2007 at National Horticultural Research Institute (NHRI), Rural Development Administration (RDA), Suwon, Korea. The cross was made in 2002 between Asiatic lily 'Orlando', a light orange colored cultivar, and 'Corrida', yellow and pink colored cultivar. Preliminarily selection was done as 'A04-72' in 2004. Multiplication and bulb formation, and characteristic tests were conducted from 2005 to 2006. The evaluation of this line was performed and named as 'Wongyo C1-84' in 2007 that was registered as 'Apricot King' to the registration office of Korea Seed & Variety Service. 'Apricot King' flowers at the end of June and grows average 121.6 cm. It flowers upward-facing, dark green throat and yellow orange (RHS 20A) with the size of flower 17.9 cm. Mean petal length and width is 12.8 cm and 3.7 cm, respectively. Leaves are 16.1 cm long and 2.1 cm wide. It shows light orange stigma and pollen. The weight and size of bulb is 64.2 g and 17.6 cm, respectively. For long-term storage, bulbs can be stored under -1 to $-2^{\circ}C$ for year-round forcing.

  • In order to promote the efficiency of strawberry breeding programs, pollen viability of strawberry, 'Seolhyang' was investigated using the fluorochromatic reaction test and seed set under controlled environment. Pistil receptivity was also assessed by hand pollination. Four varieties including 'Maehyang' were used for the test of pistil receptivity with 'Seolhyang' as a pollen parent. Pollen viability remained high for several days under dry conditions as below 33% relative humidity while the greatest loss of viability occurred at 76% relative humidity. The viability was rapidly decreased at high humidity and almost all grains were unviable in 7 days after storage. Pollen viability does not appear to be drastically reduced if the relative humidity is low. Therefore, humidity is more important factor than temperature for the pollen viability in Fragaria${\times}$ananassa. The rate of seed set by hand pollination lasted higher than the average of 77.2% from 2 to 8 days after emasculation when the daily average temperature was around $15^{\circ}C$ in plastic house. It began to decline gradually from 10 days and had decreased dramatically after 12 days except several cultivars. Based on the daily mean accumulated temperature, it is recommended to have an artificial pollination between the range of $45{\sim}140^{\circ}C$ after the emasculation to increase the rate of seed set in strawberry.

  • The effects of stigma removal from floral organ and treatment of auxin on those regions were evaluated on the fruit growth and quality in strawberry (Fragaria ananassa Duch.). The removal of stigma reduced the fruit weight, fruit length, and fruit width, while fruit growth declined as the number of removed stigma increased. The removal of stigma also resulted in reduced fruit firmness, sugar content, and total anthocyanin content, and decreased value of Hunter a for red color and increased value of Hunter b for yellow. The number of seeds deceased as the regions of removed stigma increased. The treatment of auxin on the region of removed stigma improved fruit size, while it reduced fruit firmness, sugar content, and anthocyanin content. The delay in fruit ripening was observed from both stigma removal and auxin treatment. The incidence of malformed fruits increased as the regions with removed stigma increased. The treatment of auxin also promoted fruit malformation.

  • Extrusion degree of stigma, numbers of opened florets at different time during anthesis, angle of opening florets and outcrossed seed set percent were investigated in four male sterile rices having background of Korean cultivars; Suwon 296A, Suwon 304A, Suwon 310A and Suwon 296GMS, and the Chinese cytoplasmic genetic male sterile rice Zhenshan 97A as control in order to get basic informations for hybrid rice breeding. The results obtained were summarized as follows; Extrusion degree of stigma in the four Korean male sterile lines tested was lower than in the Chinese one Zhenshan 97A. The better extrusion of stigma showed the higher outcross rate in male sterile rices. There were almost no relationships between peak of anthesis and outcrossed seed set in the male sterile rices tested. Large anthesis angle with long anthesis duration appeared to be essential for high outcrossed seed set of the male sterile rices. The genetic male sterile line showed the larger anthesis angle than the cytoplasmic and genetic male sterile one in the lines having the same background to the Korean rice cultivar Suwon 296.

  • We report a case of an 85-year-old woman with tuberculous subdeltoid bursitis. Tubeculous bursitis without adjacent joint tuberculosis may occur any site but it is rare. It is common in bursae subjected to trauma like trochanteric, prepatellar, olecranon and so on. Because the clinical findings or physical examination of tuberculous subdeltoid bursitis are similar to rotator cuff disorder and the MRI or arthroscopic findings are similar to synovial diseases, careful differential diagnosis is necessary.

  • Olecranon bursitis rarely Progresses to septic arthritis. In our case, the 24 year old woman was visited due to progressing right elbow pain, despite antibiotic treatment of chronic olecranon bursitis caused by elbow laceration 2 months ago. Pus draining sinus, localized heating and swelling could be seen on physical examination. Septic arthritis and pathologic fracture was diagnosed under arthroscopic examination. Arthroscopic irrigation and synovectomy for elbow joint, olecranon bursectomy and curettage of olecranon bone was done. In the operation field, the elbow and draining sinus over olecranon was communicated each other on saline irrigation test. The patient was treated for 3 weeks with intravenous antibiotics. At postoperative 4 weeks, bone graft was done. The possibility of chronic osteomyelitis and septic arthritis must be considered in a patient with chronic olecranon bursitis.
