Pure red cell aplasia (PRCA) and hypogammaglobulinemia are paraneoplastic syndromes that are rarer than myasthenia gravis in patients with thymoma. Good syndrome coexisting with PRCA is an extremely rare pathology. We report the case of a 50-year-old man with thymoma and PRCA associated with Good syndrome who achieved complete PRCA remission after thymectomy and postoperative immunosuppressive therapy, and provide a review of the pertinent literature.

Coronavirus disease 2019 (COVID-19) exhibits various symptoms, ranging from asymptomatic to severe pneumonia or death. The major features of patients in severe COVID-19 are the dysregulation of cytokine secretion, pneumonia, and acute lung injury. Consequently, it leads to acute respiratory distress syndrome, disseminated intravascular coagulation, multiple organ failure, and death. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative virus of COVID-19, influences nucleotide-binding oligomerization domain, leucine-rich repeat, and pyrin domain containing 3 (NLRP3), the sensor of inflammasomes, directly or indirectly, culminating in the assembly of NLRP3 inflammasome and activation of inflammatory caspases, which induce the inflammatory disruption in severe COVID-19. Accordingly, the target therapeutics for inflammasome has attracted attention as a treatment for COVID-19. Korean Red Ginseng (KRG) inhibits several inflammatory responses, including the NLRP3 inflammasome signaling. This review discusses the role of KRG in the treatment and prevention of COVID-19 based on its anti-NLRP3 inflammasome efficacy.

Teicoplanin은 actinoplanes teicomyceticus의 발효산물로서 vancomycin과 같은 glycopeptide 계열의 항균제이며, 그 작용기전은 세포벽 합성과정중 peptidoglycan의 중합을 억제하는 것으로 vancomycin과 유사하나 vancomycin과 달리 근육에 주사할 수 있으며 "red man's syndrome"이 생기지 않고 vancomycin보다 반감기가 길다. 그람양성균 감염증에 대한 teicoplanin의 효능 및 안전성을 조사하기 위하여, 그람양성균에 의한 감염증 또는 그람양성균과 그람음성균에 의한 혼합감염증이 확인되거나 의심되었던 환자 46명을 대상으로 teicoplanin과 vancomycin을 투여하였다. 투약 환자중 임상적인 반응을 평가할 수 있는 환자의 수는 vancomycin의 경우 투약환자 22명중 21명, teicoplanin의 경우 24명중 19명이였다. Vancomycin군중 임상적 반응의 평가에서 제외된 1명은 수술 후 흉막강에 MRSA 에 의한 농양으로 투약 29일째에 뇌출혈로 사망하였던 예로, 추적-배양검사에서는 MRSA가 제거 되었다. Teicoplanin군에서는 항균제 투여 중 간경변증에 의한 식도출혈 1예, 수술후 위장관 출혈 1예, 뇌 색전중 1예가 사망하였고, 1예는 Teicoplanin에 의한 심한 피부발진으로, 다른 1예는 봉와직염의 임상진단이 조직검사결과 악성종양의 근육침범으로 밝혀져 투약을 중단하였다.

The purpose of the study was to explore the effect of 2 hour infusion of vancomycin(1g) in 200ml of isotonic saline every 12 hour on the frequency of "red man syndrome", phlebitis and length of peripheral catheter placement of infected patients, in order to provide safe infusion method for reducing vancomycinin-duced RMS and phlebitis. The subjects of the study consisted of 16 hospitalized patients; 3 oncology and gastro-intestinal patients, 1 neurological patient, 6 thoracic surgical patients and 6 orthopedic patients, who had received vancomycin from July to October in 1999 at S-hospital. The dependent variables were the incidence of RMS, phlebitis and the length of peripheral catheter placement. The incidence of RMS was checked by an inspector at the first night whenever the infusion method of vancomycin was changed. RMS was observed every 15 minutes during an hour for symptoms of RMS such as itching, erythema, chest pain and systolic blood pressure. Incidence of phlebitis was assessed by inspector twice a day from the insertion of peripheral catheter to the removal of the catheter. The data were analyzed by percentage, mean, $X^2$-test, t-test, repeated ANOVA, and logistic regression analysis using the SPSSWIN program. The results are summarized as follows; 1. No significant difference was identified in frequency of RMS between the experimental group and control group. 2. There was no significant difference in the change of systolic blood pressure as the time goes on between the experimental group and control group. 3. The incidence of phlebitis was significantly lower in the experimental group than in the control group. 4. The length of peripheral catheter placement was significantly longer in the experimental group than in the control group. 5. Other drugs administrated with vancomycin didn't influence the occurrence of phlebitis. However, the infusion method of vancomycin influenced the occurrence of phlebitis. The results suggest that 2 hour infusion of vancomycin(1g) in 200ml of isotonic saline every 12 hours may decrease the incidence of phlebitis and increase the length of peripheral catheter placement compared to 1 hour infusion of vancomycin(1g) in 100ml of isotonic saline every 12 hours. However, it does not reduce the incidence of RMS.

Hookworm infections are rare causes of acute gastrointestinal bleeding. We report a middle aged man with primary nephrotic syndrome and pulmonary embolism. During the treatment with steroids and anticoagulants, the patient presented acute massive hemorrhage of the gastrointestinal tract. The results of gastroscopy showed red worms in the duodenum. Colonoscopy and CT angiogram of abdomen were unremarkable. Capsule endoscopy revealed fresh blood and multiple hookworms in the jejunum and ileum. Hookworms caused the acute intestinal bleeding. The patient responded well to albendazole. Hematochezia was markedly ameliorated after eliminating the parasites. Hence, hookworm infection should be considered in the differential diagnosis of a patient with obscure gastrointestinal bleeding. Capsule endoscopy may offer a better means of diagnosis for intestinal hookworm infections.

In the present study, the possibility of whether the pharmacological effects of Scutellariae Radix Aqueous Extracts(SR) were favorably changed by report that lipopolysaccharide(LPS)-induced rat acute lung injury was treated with Red-Koji(Monascus purpureus 12002) fermentation. Three different dosages of Red-Koji fermented SR extract(fSR), 125, 250 and 500 mg/kg were orally administered once a day for 28 days before LPS(Escherichia coli 0111:B4) treatments, and then 5 hours after LPS treatment(500 ${\mu}g$/head, intra trachea instillation), all rats were sacrificed. Changes in the body weights, lung weights, pulmonary transcapillary albumin transit, arterial gas parameters(pH, $PaO_2$ and $PaCO_2$) bronchoalveolar lavage fluid(BALF) protein, lactate dehydrogenase(LDH) and proinflammatory cytokine tumor necrosis factor-${\alpha}$(TNF-${\alpha}$), interleukin-$1{\beta}$(IL-$1{\beta}$) contents, total cell numbers, neutrophil and alveolar macrophage ratios, lung malondialdehyde(MDA), myeloperoxidase(MPO), proinflammatory cytokine TNF-${\alpha}$ and IL-$1{\beta}$ contents were observed with histopathology of the lung, changes on luminal surface of alveolus(LSA), thickness of alveolar septum, number of polymorphonuclear neutrophils(PMNs). As results of LPS-injection, dramatical increases in lung weights, pulmonary transcapillary albumin transit increases in $PaCO_2$, decreases in pH of arterial blood and $PaO_2$, increases of BALF protein, LDH, TNF-${\alpha}$ and IL-$1{\beta}$ contents, total cells, neutrophil and alveolar macrophage ratios, lung MDA, MPO, TNF-${\alpha}$ and IL-$1{\beta}$ contents increases were detected with decreases in LSA and increases of alveolar septum and PMNs numbers, respectively as compared with intact control. Especially fSR 125 mg/kg showed quite similar favorable effects on the LPS-induced acute lung injuries as compared with 60 mg/kg of ${\alpha}$-lipoic acid and 250 mg/kg of SR. The results suggest that over 125 mg/kg of fSR extracts showed favorable effects on the LPS-induced acute lung injury mediated by their antioxidant and anti-inflammatory effects. Moreover, increases of the pharmacological effects of SR on LPS-induced acute lung injury were observed by Red-Koji fermentation in this study, at least 2-fold higher.

연구배경: 폐포대식세포가 내독소에 노출되면 이 후 자극에 의해 종양괴사인자, 활성산소 등 독성이 강한 분비물 방출이 더욱 촉진되어 성인성호흡곤란증후군과 같은 각종 폐질환이 초래되는 중요한 기전으로 이해되고 있다. 그러나 문헌에 보고된 내독소에 의한 이런 priming효과는 다형핵백혈구, 단핵세포나 동물의 폐포대식세포를 대상으로 한 결과로서, 인체 폐포내에서의 폐포대식세포, 폐포상피세포 및 내독소의 상호작용을 밝히는 면에서는 한계가 있었다. 방법: 폐포상피세포에서 기원한 폐암세포주인 A549 24-well Linbro plate에 배양하여 세포단층을 형성한 후 기관지폐포세척술로 얻은 사람의 폐포대식세포($10^6/ml$)를 A549세포에 부착시켜 생체내와 유사한 환경을 만들어 실험을 시행하였다. 방법은 A549세포 부착 전후에 내독소(500 ng/ml)로 전처치한 다음 PMA, fMLP로 자극하여 방출된 과산화수소를 nM/well/2hrs 단위로 측정하여 대조군과 비교하였고 아울러 A549세포만종 없이 각 well에 직접 폐포대식세포단층을 형성한 후 동일하게 처치하였으며 결과는 다음과 같았다. 결과: 1) 24-well의 표면에 폐포대식세포단층을 형성한 후 내독소로 처치(n=7)한 경우, 대조군은 무자극군, PMA 자극군, fMLP자극군에서 각각 $9.48{\pm}2.44$, $10.38{\pm}2.34$, $10.28{\pm}2.33$ nM/well/2hrs의 과산화수소 분비능을 보였고 내독소 전처치군은 각각 $9.56{\pm}2.15$, $9.82{\pm}1.80$, $11.31{\pm}2.48$ nM/well/2hrs을 보여 내독소에 의한 priming효과는 없었다. 2) 폐포대식세포를 미리 내독소로 처치한 후 A549세포단층에 부착(n=7)시킨 경우에는 대조군의 과산화수소 분비능은 무자극군 $4.82{\pm}1.59$, PMA자극군 $8.31{\pm}1.67$, fMLP자극군 $7.06{\pm}1.82$ nM/well/2hrs이고 내독소 전처치군은 각각 $4.44{\pm}1.41$, $7.05{\pm}1.64$, $6.32{\pm}1.69$ nM/well/2hrs로서 내독소에 의한 priming 효과는 없었다. 3) 폐포대식세포를 A549세포단층에 부착시킨 후 내 독소로 처치(n=11)하면 대조군은 무자극군, PMA자극군, fMLP자극군에서 각각 $4.33{\pm}1.04$, $7.94{\pm}1.42$, $6.00{\pm}1.22$ nM/well/2hrs의 과산화수소를 분비하였고 내독소 전처치군은 각각 $5.43{\pm}1.19$, $7.56{\pm}1.31$, $6.38{\pm}1.19$ nM/well/2hrs를 보여 A549세포 부착후에도 내독소의 priming 효과는 관찰되지 않았으나 PMA나 fMLP로 자극하지 않은 무자극군에서 내독소 전처치군이 대조군에 비해 과산화수소 분비능의 유의한 증가를 보였다(p<0.05). 결론: 이상의 결과는 사람 폐포대식세포에서 내독소에 의한 priming효과는 없으나 폐포상피세포와의 상호작용에 의해 내독소가 폐포대식세포를 직접 자극함을 시사하는 소견이며 향후 추시가 필요할 것으로 사료된다.
