To make a new fairy ring of Tricholoma matsutake in situ, the way of production and transplanting of ectomycorrhizal seedlings of T. matsutake using Pinus densiflora was investigated after transplanting from 2000 to 2005 as well as the method to improve their survival rate for the fungus. For the production of ectomycorrhizal pine seedlings, the seedlings planted at the edge of fairy ring of T. matsutake in November showed 97% of the survival rate, while those planted in April showed 80% of the rate. For the complete infection of the T. matsutake, it required more than two years after planting. The infection rate of mycelia for the ectomycorrhizal seedlings was 17.6% when the natural seedlings were used, whereas it was relatively low when the seedlings prepared from the nursery were used. The survival of T. matsutake mycelium reached up to 22% by the transplanting in April, while the mycelium transplanted in October and November showed less than 5% of the survival. The survival of T. matsutake on the transplanted seedlings was the highest in the seedlings having 50% of infection rate before transplanting. Excavation of the ectomycorrhizal seedling to examine the vitality of ectomycorrhizal roots of T. matsutake resulted in the perishing of them. Therefore, the method using a 'rice bag triers' to check living mycelium of T. matsutake without digging of transplanted seedlings was introduced in this study. In addition, it is recommended that the examination has to be conducted at least two years after transplanting.

Trees, cultivated in containers, are appropriate in soil deformation such as road sites with cutting and filling. This study tested the effectiveness of trees produced in containers for early rootage in street tree transplantation. For the study, Korean Mountain Ashes(Sorbus alnifolia) were used for experimental groups. The groups were categorized into three categories: trees cultivated in containers with mulching treatment(group A), trees cultivated outdoors with mulching treatment (group B), and trees cultivated in containers with weeding treatment(group C). Each group consisted of ten trees of the same size and transplanted to the experimental site. In order to compare each group's rootage, the study was carried out with the chlorophyll fluorescence method by the analysis of photochemical reaction. As a result of the study, group B had the lowest the maximum fluorescence amount(P). The amount of fluorescence increased by OJ transition of the process, and appeared to reduce the photosystem II electron transport efficiency. In photosystem II, electron transfer energy flux through photosystem I(RE1o/RC, RE1o/CS) was also reduced by more than 20% in group B. These results may imply that transplantation of container-cultivated trees with mulching treatment provides the most rapid rootage among the groups. The weeding treatment is also more effective than mulching treatment for rapid rootage of street trees.

In the benign bone tumor such a fibrous dysplasia, destructive lesion is generally treated by curettage and simple bone graft. Such lesions are unlikely to recur if treated local curettage with bone graft or simple excision of the lesion. When it is impossible to cure only with simple bone graft due to wide extent of tumor, vascularized fibular graft have been introduced for functional loss and appearance. The recurrence of the primary tumor in the grafted fibula is rare in benign bone lesion. We experienced a case of fibrous dysplasia which was recurred in the grafted fibula following the initial treatment with vascularized fibular graft. So we report a case of our experience.

Cytomegalovirus (CMV) is the single most common infection following kidney transplantation and despite prophylactic strategies and the development of new antiviral agents, it still remains a cause of considerable morbidity and mortality. Current literature suggests that CMV infection may trigger rejection. We report a case of late CMV disease in a preemptive seropositive recipient who did not receive CMV prophylaxis. Diarrhea and abdominal cramping persisted after the administration of mycophenolate mofetil (MMF) six months after transplantation and resulted in ileal perforation at eight months after transplantation. The boy recovered after six weeks of treatment with ganciclovir. MMF has been mooted as a risk factor for CMV infection since its introduction, and further investigations are required to confirm its role. More attention to infectious complications is necessary and serial monitoring of viral load is recommended when MMF is administered.

Purpose: The purpose of this report was to assess a surgical technique-using an autogenous tricortical iliac crest bone graft in patients with epilepsy-for anatomical glenoid reconstruction for recurrent anterior glenohumeral instability with severe glenoid deficiency. Materials and Methods: We studied two cases of recurrent anterior dislocation of the shoulder due to epilepsy. These cases were treated with anatomical glenoid reconstruction using an autogenous tricortical iliac crest bone graft. Results: Both cases achieved bone union in 5 months. There was no recurrence of instability and pain. Both cases had normal range of motion. Conclusion: Anatomical glenoid reconstruction for recurrent anterior glenohumeral instability with severe glenoid deficiency using an autogenous tricortical iliac crest bone graft is a successful surgical technique for achieving shoulder stability.

Destruction of normal temporomandibular joint architechture may produce serious functional and cosmetic deficiencies. The literature is well documented as to the etiology and pathogenesis of temporomandibular joints. Numorous surgical procedure have been advocated for temporomandibular joint ankylosis from condylectomy to arthroplasty, cartilage transplant, metallic prosthesis, interpositional implant. These were to able reconstruct the normal mandibular function, and any even procedure could obtain the satisfactory results. In this paper, we reviewed young adult patient with TMJ ankylosis and facial asymmetry who was treated with metallic condylar prosthesis and orthognathic surgery.

Twenty-six renal allograft biopsies which showed acute rejection and had renal capsule and medulla in the same specimen were selected in order to compare the severity of acute rejection between superficial cortex, deep cortex and medulla. Disregarding the mid cortical region, the superficial cortex was considered as being one-third of the distance from the renal capsule to the medulla and the deep cortex as being that one-third of the cortex which was adjacent to the medulla. Using semiquantitative histologic analysis the following parameters were compared in superficial cortex, deep cortex, and medulla: interstitial inflammation, edema, tubulitis, and acute tubulointerstitial rejection grade. Also, the presence of lymphocyte activation and polymorphonuclear leukocytes was evaluated. Significantly greater histologic changes of acute rejection were found in the deep cortex vs. supeficial cortex for the following parameters: interstitial inflammation(P=0.013), edema (P=0.023) and tubulointerstitial rejection grade(P=0.016). These findings support the view that biopsies in which deep cortex is not included may result in underestimation of the severity of renal allograft rejection.

This study was carried out to determine whether genistein implants in laying hens could be transferred into their eggs. 250 mg genistein pellet was implanted two or four subcutaneously in the neck of laying hens. The contents of genistein in egg yolk transferred were analyzed with HPLC-MS. In 500 mg genistein pellets, it was detected as 395 ng/egg yolk on the day 18 after implanting and maintained as 546 ng/egg yolk after the day 59. In 1,000 mg, genistein was detected as 240 ng/egg yolk on the day 13, as 514 ng/egg yolk on the day 30 and maintained over 59 days. In conclusion, the direct genistein implants could be more twenty times efficiently transferred to egg yolks than dietary supplement.

These studies were carried out to improve the reproductive efficiency through embryos transfer of Hanwoo IVM/IVF embryos. Following routine IVM/IVF procedure, oocytes and zygotes were cultured far 40 to 44 h in CRlaa medium with BSA. Then 2 to 8-cell embryos were removed the cumulus cell and were cultured in CRlaa medium containing 10% fatal bovine serum and 2.5 mM taurine in 5% $O_2$ and 5% $CO_2$ at 38.5$^{\circ}C$. The fresh embryos of the morulae and blastocysts cultured for 6 to 9 days in vitro or the frozen-thawed embryos were transferred into recipients. The pregnancy rates of the blastocyst produced for 6, 7, 8, and 9 days in vitro culture were 59.4, 68.2, 66.0 and 100%, respectively. In the developmental stage, pregnacy rates of early blastocysts (61.1%), blastocysts(64.7%) and expanded blastocysts(69.5%) were higher than that of morulae stage(20.0%). The pregnancy rates according to the corpus luteum grades of A, B and C in recipients were 73.6, 62.9 and 50.0%, respectively. Effects of donor-recipients synchrony of after day 2, 1 and 0, before day 1 and 2 on the pregnancy rates were 35.7, 65.5, 72.6, 67.9 and 60.0%, respectively. Pregnancy rates of the body condition score of recipients $\leq$2(71.3%) were higher than those of $\geq$3.0 score(40.0%). The pregnancy rates according to the parity of recipients when embryo was transferred to cow(70.6%) was higher than in heifer(59.1%). The pregnancy rates according to hormone treatment before embryo transfer were 69.9% in hCG + GnRH administration group and 63.0% in control group. Fresh and frozen-thawed embryos on the pregnancy rates were 70.6 and 36.4%, respectively. Pregnancy rates in single and AI+single was 90.0% and 64.8%. Pregnancy rates in twin induction was better than in single. These results indicate that pregnancy rates after transfer were affected on the embryo ages, donor-recipient synchrony, body condition score of recipients, corpus luteum status, parity and hormone treatment to recipients.
