윤지희,오민주,안지영,SEKHONSIMRANJEET SINGH,김양훈,민지호 대한독성 유전단백체 학회 2016 Molecular & cellular toxicology Vol.12 No.2

Pigmentary disorders generally indicate that an increased amount of melanin, leading to darker color of skin, called hypermelanosis. Thus, several methods were studied for finding therapy of hypermelanosis until now in worldwide. In this study, the hypermelanosis reduction has been observed with daily lysosome-related organelles (LRO) extract from eggwhite. The scrub was used for enzyme extraction so as to maintain the stability of the extracted enzyme. The LRO extracts were divided and into two groups: free enzyme and fresh enzyme. Free enzyme was extracted on the first day from the LRO and fresh enzyme was extracted by scrub from LRO daily. The melanin dissolved phosphate buffer (pH 7.0) was treated by two groups of enzymes for a period of 30 days. The fresh enzymes were found to be more effective than the free enzymes. The activity of free enzymes decreases with time and as a result it could not degrade melanin after 36 days. The peroxidase activity was also measured and it matched with the results of previous studies. Therefore, the daily fresh enzymes displayed remarkable ability in hypermelanosis reduction than with free enzyme that lost its activity after some time. The present work can be potentially used for dermal disease in medical industry and also in cosmetic products.

In order to prepare the uniform copper particles from copper chloride solution, the reduction behavior of copper particles from copper chloride and the effects of reduction agent and dispersing agent was investigated. In the case that 2.56 M of $C_6H_8O_6$ was used as a reduction agent, the highly dispersed Cu particles with sharp size distribution were generated from 0.96M of copper chloride solution, and the size of Cu particles was $6\~10\;{\mu}m$. To form $Cu(NH_3)_4Cl_2$ complex solution, $NH_4OH$ was added in the copper chloride solution before the reductive reaction of Cu ion. The generated Cu particles have a two kind of shape, spherical and rod-like. In the case that $N_2H_4{\cdot}H_2O$ was used as a reduction agent, the very fine spherical Cu particles with the size of $0.2\~0.5\;{\mu}m$ was obtained. Arabic gum as a dispersing agent was more effective than $Na_4P_2O_7{\cdot}10H_2O$.

Purpose: This study was conducted to investigate the predictors of kidney outcome after laparoscopic adrenalectomy in patients with primary aldosteronism (PA). Materials and Methods: We retrospectively reviewed the medical records of 74 patients who underwent unilateral adrenalectomy for the treatment of PA from January 2011 to December 2019. Patient characteristics and serial data on postoperative changes in kidney function were analyzed and compared between the two groups according to the presence of acute kidney injury (AKI). Postoperative AKI was defined as a decline in the estimated glomerular filtration rate (eGFR) of >50% or an increase in the serum creatinine level of ≥0.3 mg/dL at 1 week after surgery compared with perioperative levels. Chronic kidney disease (CKD) was defined as an eGFR < 60 mL/min/1.73 m2 present for 3 months. Results: Nineteen patients (25.7%) had postoperative AKI. Patients who experienced postoperative AKI had higher aldosterone-to-renin ratios, higher rates of dyslipidemia, and more left ventricular hypertrophy than did patients without postoperative AKI (p=0.015, 0.036, and 0.033, respectively). Twenty-eight patients (37.8%) had CKD at 6 months after surgery, including 15 patients who had newly progressed to CKD postoperatively. In the multivariate regression analysis of patients without preoperative CKD, the only independent predictor of the progression to CKD was preoperative albuminuria (p=0.007). Conclusions: In this study, one-quarter of the patients had postoperative AKI after unilateral adrenalectomy for the treatment of PA. However, postoperative AKI was not directly correlated with CKD progression. Preoperative albuminuria was an independent predictor of the progression of CKD.

Lung Related Complications in Patients with Advanced Thyroid Cancer during Lenvatinib Therapy: Case Series and Literature Review

윤지희,홍아람,김희경,강호철 대한갑상선학회 2022 International Journal of Thyroidology Vol.15 No.1

Lenvatinib prolongs the survival of patients with advanced thyroid cancer. At initiation of lenvatinib therapy,advanced thyroid cancer patients frequently have lung metastasis and are vulnerable to pulmonary complicationsdue to concealed lung damage caused by previous therapies including radioactive iodine (RAI) therapy. Among24 patients treated with lenvatinib, pulmonary events were observed in three patients with lung metastasis,including one with interstitial lung disease (ILD) and two with pneumothorax. One patient who was previouslytreated with 750 mCi RAI developed uncontrolled ILD after lenvatinib therapy and died of respiratory failure. Twopneumothorax cases had previous cavitation of metastatic lung nodules. Pneumothorax resolved spontaneouslyin both patients. Pulmonary events in patients with lung metastases treated with lenvatinib are uncommon andmanageable in most cases, but may be fatal if detection and management are delayed. Special attention shouldbe given to patients with lung metastasis treated with high cumulative dose of RAI therapy or cavitary changesthat develop after lenvatinib therapy.

Background: The association between Graves’ disease (GD) and co-existing thyroid cancer is still controversial and most of the previously reported data have been based on surgically treated GD patients. This study investigated the clinicopathological findings and prognosis of concomitant thyroid cancer in GD patients in the era of widespread application of ultrasonography. Methods: Data of GD patients who underwent thyroidectomy for thyroid cancer between 2010 and 2019 in three tertiary hospitals in South Korea (Asan Medical Center, Chonnam National University Hwasun Hospital, and Pusan National University Hospital) were collected and analyzed retrospectively. In the subgroup analysis, aggressiveness and clinical outcomes of thyroid cancer were compared nodular GD and non-nodular GD groups according to the presence or absence of the thyroid nodules other than thyroid cancer (index nodules). Results: Of the 15,159 GD patients treated at the hospitals during the study period, 262 (1.7%) underwent thyroidectomy for coexisting thyroid cancer. Eleven patients (4.2%) were diagnosed with occult thyroid cancer and 182 patients (69.5%) had microcarcinomas. No differences in thyroid cancer aggressiveness, ltrasonographic findings, or prognosis were observed between the nodular GD and non-nodular GD groups except the cancer subtype. In the multivariate analysis, only lymph node (LN) metastasis was an independent prognostic factor for recurrent/persistent disease of thyroid cancer arising in GD (P=0.020). Conclusion: The prevalence of concomitant thyroid cancer in GD patients was considerably lower than in previous reports. The clinical outcomes of thyroid cancer in GD patients were also excellent but, more cautious follow-up is necessary for patients with LN metastasis in the same way as for thyroid cancer in non-GD patients.

본 연구는 PC방의 세균 오염 실태를 조사하기 위한 목적으로 2004년 7월${\~}$12월까지 서울시내에 있는 PC방(Internet Cafe)들 중에서 34곳을 표본으로 선정하여 연구를 수행하였다. 총 세균수를 측정한 결과, 키보드에서는 $9.0{\times}10^4$ CFU/ml, 마우스에서는 $2{\times}10$ CFU/ml, 그리고 화장실 손잡이에서는 $5{\times}10^3$ CFU/ml의 세균이 검출되었다. 이는 화장실 손잡이보다 키보드와 마우스에서 세균에 대한 오염정도가 더 심한 것을 의미한다. PC방에서 항생제에 대한 내성을 지닌 7개의 균주를 분리해 내었는데, 2개의 균주는 methicillin과 erythromycin에 대한 내성을 나타내었고, 5개의 균주는 gentamicin, ampicllin, cefotaxim, chloramphenicol에 대해서 내성을 나타내었다. 이들 균주들을 동정한 결과, 2 균주는 Staphylococcus aureus로 동정되었고, 4 균주는 Actinobacillus ureae로 동정되었으며. 나머지 1개의 균주는 Pasteurella multocida로 동정되었다. Pasteurella multocida와 Actinobacillus ureae는 잠재적인 병원균으로 이전에 Pasteurella ureae로 알려졌던 Actinobacillus ureae는 인간의 상부 호흡기에 드물게 공생하는 것으로 알려졌으며, Pasteurella multocida는 많은 가축의 비인두강 안에 존재하는 평범한 정상 균총을 구성하는 세균인 것으로 알려졌다. 항생제 내성에 대한 연구 결과 Staphylococcus aureus는 erythromycin과 methicillin의 혼합제에 대해서 $100\;{\mu}g/ml$ 이상의 높은 항생제 내성을 나타내었고, Pasteurella multocida와 Actinobacillus ureae는 gentamicin, ampicillin 에 대하여 $100\;{\mu}g/ml$ 이상의 높은 항생제 내성이 있음을 알 수 있었다. This study was performed to investigate the hygiene condition of PC room(internet cafe) in Seoul Korea. From July 2004 to December, 34 samples were collected, there's an average of $9.0{\times}10^4$ CFU/ml on keyboards, $2{\times}10$ CFU/ml on mouse and $5{\times}10^3$ CFU/ml on door konbs toilets, suggesting that keyboards and mouse are more contaminated than toilet door knobs. Seven antimicrobial resistant strains were isolated from PC Rooms. Two isolates were resistant to methicillin and erythromycin, while five isolates were resistant to gentamicin, ampicllin, cefotaxim, and chloramphenicol. By identification, these strains were identified as Staphylococcus aureus (2 strains). Actinobacillus ureae (4 strains) and Pasteurella multocida (1 strain), respectively. Pasteurella multocida and Actinobacillus ureae are potentially pathogenic bacteria. Actinobacillus ureae, formerly, known as Pasteurella ureae, is an uncommon of the upper respiratory tract in humans. Pasteurella multocida is a part of the normal flora in the nasopharynx of many domestic animals. We concluded that Staphylococcus aureus is highly resistant to erythromycin and methicillin over $100\;{\mu}g/ml$, while Pasteurella multocida and Actinobacillus ureae is highly resistant to gentamicin, ampicillinover over $100\;{\mu}g/ml$.
