  • A 13-year-old girl was diagnosed with non-cystic fibrosis (CF)-related multifocal bronchiectasis accompanied by nephrotic-range proteinuria of unknown cause. On renal biopsy, there were many segmental homogeneous deposits of amyloid tissue with positive Congo red staining in the glomeruli and interstitium. On electron microscopy, relatively straight, non-branching, randomly arranged amyloid fibrils were showed in the mesangium of the glomeruli. These fibrils were approximately 10 nm in diameter, compatible with secondary amyloidosis. Her level of serum amyloid A was remarkably elevated. To our knowledge, this girl is the first case of secondary renal amyloidosis induced by bronchiectasis in Korean children.

  • We have investigated that a couple of soft ferrite ceramic powders having a spinal structure have shown the effect on growth and secondary metabolites production of some medicinal plants cultured in vitro. The addition of the ceramic powders as bare state to culture medium has stimulated the growth of Achyranthes japonica callus and plantlet, adventitious root of Hyoscyamus niger and Platycodon grandiflorum hairy root about 65, 75, 150 and 50%, respectively. Whereas Centella asiatica callus and plantlet, Scopolia parviflora hairy root, and Hyoscyamus albus adventitious root were not affected markedly. Moreover, the ceramic powder has enhanced the growth of H. niger adventitious roots even under conditions of irradiating alone without any direct contact between ceramic powder and media. Based on growth stimulation effect, the ceramic powders have enhanced the gross production of tropane alkaloid in H. niger adventitious root, and polyacetylene in P. grandiflorum hairy root about 35 and 30%, respectively.

  • 리그닌함량이 감소한 펄프소재의 육성을 위해 OMT유전자와 리그닌생합성 간의 관계를 2종의 포플라 수종을 이용하여 실험하였다. OMT유전자의 발현은 리그닌생합성이 가장 많이 일어나는 developing secondary xylem에서 높앗다. 이 사부조직에서의 리그닌함량의 증가는 봄에 성장을 개시할 때부터 증가하기 시작하여 8월 말 경에 가장 높았다. 이러한 리그닌의 증가는 OMT유전자의 발현 증가와 일치하였으며, 이는 OMT유전자가 리그닌생합성에서 매우 중요한 역할을 함을 나타내는 것이다.

  • Chronic Achilles tendon rupture is likely to result in functional impairment in gait and sports activity. The presence of a large defect secondary to retraction of the tendon ends, atrophy of the calf muscles, and vulnerable vascularity of the soft tissue envelope make it a challenging problem to treat. Surgical reconstruction aims to restore the length and tension of the gastrocnemius-soleus complex. Various surgical treatment options have been described, depending on several factors, including residual gap size after scar tissue removal, remaining tissue quality, and vascularity. Despite good results being reported, there is a lack of high-level, evidence-based clinical guidelines available to select the first-line surgical procedure. This paper overviews the current available surgical options for patients with chronic Achilles tendon rupture.

  • The aim of this case report is to present a case of 68-year-old male with a history of multiple myeloma and the intravenous use of Zometa (zoledronic acid) who had developed medication-related osteonecrosis of the jaw (MRONJ) following a hot pizza burn to the palate. Clinical and radiographic findings revealed grade 1 MRONJ of the right side of the hard palate. Soft tissue trauma and delayed epithelialization may be associated with some cases of MRONJ. Patients on anti-resorptive medications or anti-angiogenic drugs should be informed of the risk of bone exposure and subsequent MRONJ secondary to physical/chemical insults to the bone and soft tissue in the oral cavity.

  • A depressed alvelolar ridge and a collapsed interdental papilla in the anterior region may interfere with esthetic prosthodontic repair. The resultant sequelas will cause overcontoured prosthesis or dark shadow under pontic which may not suffice our patients' esthetic demands. So, surgical periodontal treatment has been needed for esthetic repair in deformed ridges and extensive interproximal spacing. Our treatment option alters Dr.Abram's roll technique to make palatally extended connective tissue secondary pedicle flap to obtain additonal connective tissue. Blood supply maintenance, least trauma, and no secondary wound is advantages in this modification.

  • The oral lesion of acquired syphilis - primary, secondary, and tertiary - is comparatively rare. Most of the time secondary syphilis manifests itself as a systemic disease with maculopapular eruptions of the skin, generalized lymphadenopathy, fever, and occasional eruptions on the mucous membranes. The lesions of the tertiary stage may occur anywhere in the body, including the oral cavity. Necrotizing faciitis of the head and neck is an uncommon, rapidly spreading soft tissue infection of polymicrobial origin characterized by extensive necrosis and gas formation in the subcutaneous tissue and superficial fascia. This is characterized by its fulminating, devastating, and rapid-progressing course. The mortality rate is high if it is not treated promptly and vigorously. Patients with an impaired immune system and those with small-vessel disease such as diabetes mellitus are more prone to develop this infection.

  • 국내 두 품종의 고구마를 대상으로 경단분열조직 배양에 의한 체세포배발생과 이들로부터 식물체 재분화 체계를 확립하였다. '부여재래' 나 '율미'의 경단분열조직 절편을 1mg/L 2,4-D가 첨가된 MS배지에서 배양하여 6주후에 80% 이상의 절편으로부터 배발생 캘러스를 얻었다. 이 캘러스를 0.1 mg/L 24-D와 0.1 mg/L kinetin이 첨가된 배지에 옮겼을때 '부여재래' 와 '율미'의 체세포배 발생률이 각각 71% 및 63%로 다른 처리에 비해 현저히 높았다. 형성된 체세포배를 상하로 이등분하여 1 mg/L 2,4-D가 첨가된 MS배지에 치상하였을 경우 품종에 관계없이 길이가 짧은 체세포배의 상반부에서 이차배가 더 많이 발생하였다. 이들 체세포배는 MS 기본배지에서 90% 이상이 완전한 식물체로 발달하였다. 이러한 결과는 우리가 이전에 확립하였던 고구마의 경단분열조직으로부터의 체세포배발생 방법(SABRAO J 21:93-101)이 광범위한 고구마 계통에 적용될 수 있음을 시사한다.

  • Purpose: The aim of this study was to identify a role for endodontic intervention in enhancing the regenerative potential of the periodontal ligament when combined with periodontal treatment in seriously involved teeth with a secondary endodontic component. Methods: Patients who exhibited radiolucency extending to the periapical region, abnormal electric pulp testing values, and deep probing depth derived from primary periodontal disease with secondary endodontic involvement were included. Intentional root canal treatment was applied to those teeth in which the apical lesions were presumed to communicate with those of the periodontal lesion of the teeth that remained vital. In all three selected cases, regenerative periodontal therapy incorporating either bone graft or guided tissue regeneration was instituted 3 months after the endodontic intervention. Results: Remarkable enhancement in radiographic density was noticeable around the affected teeth as evidenced by changes in radiopacity. There was a significant reduction in the probing pocket depth and gain in the clinical attachment level. Chewing discomfort gradually disappeared from the commencement of the combined treatment. Conclusions: An intentional endodontic intervention may be a worthwhile approach for the sophisticated management of teeth suffering from serious attachment loss and alveolar bone destruction with concomitant secondary endodontic involvement.
