Management of soil water and fertilization is known to primarily affect physiological properties and yield in plant. The effect of soil water potential and nitrogen application on characteristics of photosynthesis and chlorophyll fluorescence in Schisandra chinensis Baillon was investigated on a sandy loam soil. Net photosyntheis rate and transpiration rate increased as a photon flux density and was highest at –50kPa of soil water potential. Light compensation point (1.5 μmol m<SUP>-1</SUP> s<SUP>-1</SUP>) and dark respiration (0.13 μmol CO₂ m<SUP>-1</SUP> s<SUP>-1</SUP>) was lowest at -50 kPa but maximum photosynthesis rate (13.10μmol CO₂ m<SUP>-1</SUP>s<SUP>-1</SUP>) and net apparent quantum yield(0.083 μmol CO₂ m<SUP>-1</SUP> s<SUP>-1</SUP>) was highest at -50 kPa. As results of chlorophyll fluorescence by OJIP analysis, maximum quantum yield (Fv/Fm) of photosystem II (PSII) and PIabs was higher in treatments of –50 kPa and -60 kPa respectively, which reflects the relative reduction state of PSII. But the relative activities per reaction center such as ABS/RC and DIo/RC were low with decreasing soil water potential. Net photosyntheis rate and transpiration rate were highest at treatment of soil testing 1.0 times (92 kg ha<SUP>-1</SUP>). Application of nitrogen resulted in high Fv/Fm, PIabs and low ABS/RC, DIo/RC. This result implies that -50 kPa of soil water potential and nitrogen fertilizer may improve the efficiency of photosynthesis through controlling a photosystem in Schisandra chinensis Baillon.

Purpose: The aim of this study was to evaluate and compare the surgical outcomes of endoscopic total and near-total thyroidectomies in patients with thyroid cancer. Methods: Between February 2000 and January 2009, among 387 patients who underwent endoscopic thyroidectomy in our hospital, we evaluated 50 patients who underwent endoscopic total or near-total thyroidectomy. Thirty- five and 15 patients underwent endoscopic total thyroidectomy and near-total thyroidectomy, respectively. We analyzed the patients' clinicopathologic characteristics and post-operative complications between the two groups. Results: The mean size of tumors was 1.08 cm (range, 0.1∼3.5 cm) and the mean operative time was 192 minutes. Forty-nine tumors were papillary cancers and 1 tumor was a follicular cancer. Two patients in the endoscopic total thyroidectomy group underwent re-operation because of bleeding. In the near-total thyroidectomy group, one patient had transient hypocalcemia and one patient had temporary recurrent laryngeal nerve palsy. In the total thyroidectomy group, nine patients had transient hypocalcemia and one patient had temporary recurrent laryngeal nerve palsy. There was no statistical difference in the post-operative complicationrates between the two groups (P=0.254 for hypocalcemia and P=0.470 for injury to the recurrent laryngeal nerve). Conclusion: Based on our experience, endoscopic total thyroidectomy is a safe and feasible alternative to endoscopic near-total thyroidectomy. (Korean J Endocrine Surg 2009; 9:201-205)

목적: 아메드밸브삽입술 및 트리암시놀론 테논낭밑주사를 시행한 녹내장 환자에서 결막 괴사가 발생한 1예를 보고하고자 한다. 증례요약: 22세 여자 환자가 타 병원에서 우안 섬유주절제술 후 반복적인 마이토마이신 C 결막밑주사에도 불구하고 안압이 조절되지 않아 내원하였다. 우안에 아메드밸브삽입술을 시행하면서 트리암시놀론 테논낭밑주사를 병행하였고, 4주 후 결막 괴사가 관찰되었다. 괴사 부위를 제거하였으나 결막 괴사가 재발하여 자가결막이식술을 시행하였다. 한 차례 더 결막 괴사가 재발하여 양막이식술을 시행 하였고 이후 결막 상피가 완전히 회복되었다. 결론: 트리암시놀론 주사 후 결막 괴사는 매우 드문 합병증으로 알려져 있다. 하지만 본 증례의 환자처럼 이전에 반복적인 마이토마이신 C 결막밑주사와 같이 결막의 조직학적 약화를 초래할 수 있는 기왕력이 있는 경우에서는 발병 위험이 더 높을 수 있을 것으로 보이며, 적극적인 수술적 치료가 결막 상피의 재건에 도움이 될 것으로 보인다. Purpose: We report a case of conjunctival necrosis in a glaucoma patient who underwent Ahmed valve implantation and subtenon triamcinolone injection. Case summary: A 22-year-old female was referred to our clinic for uncontrolled intraocular pressure despite trabeculectomy and repeated subconjunctival injections of mitomycin C in her right eye. Ahmed valve implantation and subtenon triamcinolone injection were performed in the right eye. Four weeks later, conjunctival necrosis was observed. After debridement of necrotic tissue, an additional conjunctival autograft was needed because of recurrence of the conjunctival necrosis. After amniotic membrane transplantation was performed for one more recurrent conjunctival necrosis, conjunctival epithelialization was completed. Conclusions: Although conjunctival necrosis after periocular injection of triamcinolone is a rare complication, previous multiple usage of antimetabolites such as mitomycin C might be associated with a higher risk of developing conjunctival necrosis. In such cases, aggressive surgical intervention may be helpful in the reconstruction of the conjunctival epithelium. J Korean Ophthalmol Soc 2018;59(9):887-892

Purpose: An association between primary hyperparathyroidism and well differentiated thyroid carcinoma has been frequently reported. However, there have been few reports of secondary hyperparathyroidism associated with thyroid carcinoma. This study was performed to evaluate the prevalence of thyroid nodule including thyroid carcinoma in patients with secondary hyperparathyroidism and to suggest more proper diagnostic approach for such cases. Methods: A retrospective study was performed on fifty-two patients who underwent parathyroid surgery for secondary hyperparathyroidism between March, 1986 and December, 2003. Results: In 20 patients (38.5%), thyroid surgery was added because of coexistent thyroid nodules. Five (25%) out of the 22 patients with coexistent thyroid nodule had thyroid carcinoma. Among the 5 thyroid carcinoma patients, 4 had papillary carcinomas and one had a follicular carcinoma. Mean size of thyroid carcinomas was 1.4 cm (0.3∼3.0 cm). Conclusion: The prevalence of thyroid carcinoma in patients with secondary hyperparathyroidism was higher than that in the general population. An aggressive diagnostic approach (ultrasonography and FNAB) should be considered when the patients with secondary hyperparathyroidism present with thyroid nodules.

Background: Onychomycosis, especially toenail onychomycosis has become one of the common fungal infection and has historically been regarded as a cosmetic rather than medical problem by many patients, even by physicians. Recently, however, there are several reports that is a refractory disease which may cause a deleterious effect on patiets quality of life (QOL). Objective: The purpose of this study was to investigate the impact of toenail onychomycosis on QOL in Korea and to assess the chandes of QOL after treatment. Methods: Total 1004 patients with toenail onychomycosis which was confirmed by clinical findings and KOH preparation were were enrolled at 47 dermatologic centers in Korea, and interviewed with standardized QOL questionnaire before and after sytemic antifungal treatment. Responses to the questionnaire were scored by 5-point scale (1∼4) and averaged, and were analyzed for 5 dimensions of emotional impact, social impact, symptorn and functional impact, patients views concerning treatment, and relationship with doctor. Results: 1. Before and after treatment, the most serious impact was emotional dimension showing 1.90 and 1.30 in average score (AS), and social (AS: 1.14 and 0.83) and symptom and functional impact (AS: 1.05 and 0.92) was also affected. 2. In female rather than male, statistically more significant impact on patients QOL was observed in all dimensions. 3. After treatment, 3 of 5 dimensions were improved significantly - emotional dimension (AS : from 1.90 to 1.30), social dimension (AS: from 1.14 to 0.83), patients view concerning treatment (AS: from 1.34 to 1.02). 4. The drgree of patients satisfaction at the therapeutic effect was very high- 62.4% (immediately after treatment) and 65.8% (9 months affer initiation of treatment) of patients answered excellent or good. Conclusion: This study confirms that toenail onychomycosis has significant impact on the overall QOL of patients. Also the effect of antifungal therapy on patients QOL were watisfactory. Therefore, both doctor and patient should pay more attention to the treatment of onychomycosis. [Kor J Med Mycol 3(1): 115∼124]
