This case report that the therapeutic effects of traditional Korean medicine(TKM) treatment on the tumor response in a diffuse large B-cell lymphoma(DLBL) patient. A patient was treated by acupuncture, pharmacopuncture, moxibustion, cupping and herbal medicine once a week at least for 12 months. we evaluated the grade of chief complaints and performed blood tests and sonography, abdominal CT periodically. After 1 month administration with TKM treatment, the symptoms of the patient vanished obviously. the size of inguinal lymphoma decreased gradually through 3 months. then from 3 to 10 months, the size of inguinal lymphoma remained as it is. TKM treatment was maintained continuously. in the abdomino-pelvic CT performed after 12 months, the patient didn't complain any symptom and the size of inguinal lymphoma decreased a little again. This case study supports that TKM treatments may have a efficacy in treating diffuse large B-cell lymphoma(DLBL) patients.

Selenium (Se)-rich binary Cu-Se and In-Se nanoparticles (NPs) were synthesized by a modified heat-up method at low temperature ($110^{\circ}C$) using the gum exudates from a cherry blossom tree. Coating of CISe absorber layer was carried out using Se-rich binary Cu-Se and In-Se NPs ink without the use of any external binder. Our results indicated that the gum used in the synthesis played beneficial roles such as reducing and capping agent. In addition, the gum also served as a natural binder in the coating of CISe absorber layer. The CISe absorber layer was integrated into the solar cell, which showed a power conversion efficiency (PCE) of 0.37%. The possible reasons for low PCE of the present solar cells and the steps needed for further improvement of PCE were discussed. Although the obtained PCE is low, the present strategy opens a new path for the fabrication of eco-friendly CISe NPs solar cell by a relatively chief non-vacuum method.

Glutathione (GSH) is a chief cellular antioxidant, affecting stem cell functions. The cellular GSH level is dynamically altered by the redox buffering system and transcription factors, including NRF2. Additionally, GSH is differentially regulated in each organelle. We previously reported a protocol for monitoring the real-time GSH levels in live stem cells using the reversible GSH sensor FreSHtracer. However, GSH-based stem cell analysis needs be comprehensive and organelle-specific. Hence, in this study, we demonstrate a detailed protocol to measure the GSH regeneration capacity (GRC) in living stem cells by measuring the intensities of the FreSHtracer and the mitochondrial GSH sensor MitoFreSHtracer using a high-content screening confocal microscope. This protocol typically analyses the GRC in approximately 4 h following the seeding of the cells onto plates. This protocol is simple and quantitative. With some minor modifications, it can be employed flexibly to measure the GRC for the whole-cell area or just the mitochondria in all adherent mammalian stem cells.

Three strains which accumulated large quantities of L-hlutamic acid as the chief product of metabolism in the presence of glucose and inorhanic ammonium salt under the aerobic condition sere newly isolated. These strains have the general characters as follows: Gram-positive, short fod-shaped, non-sporulating, non-motile, and facultative anaerobe. A change of cell shates was not almost observed in their life cycles and neither a phenomenon of cell-elongation nor a pleomorphism was recognized in any cases. Together with rigid stability in Gram-stain, these characters as above indicated evidences that newly isolates would belong to genus Brevibacterium clearly differentiated from genus Corynebacterium. At the same time the newly isolates, in addition to nutritional requirement of biotin and thiamine, showed the distinctive character of requirement of special amino acid such as histidine or cysteine for their considerable growth. These physiological characters including nitrates reduction, reaction on milk, and slow formation of acid from sugar also were useful in confirming that these bacteria would be Brevibacterium ammoniagenes.

The malignant germ cell tumor found in the gonad can originate in the anterior mediastinum. Endodermal sinus tumor[Yolk sac tumor] is a kind of malignant germ cell tumor and is derived from extra-embryonic mesoderm. We experienced a case of primary mediastinal endodermal sinus tumor occurred in 22 year old male patient. His chief complaint was anterior chest pain for 2 days. The tumor located in the anterior mediastinum and invaded upper lobe of the deft lung and pericardium. A left upper lobe resection including phrenic nerve and pericardium was performed and the tumor in the anterior mediastinum was excised. The patient has been treated with combination chemotherapy[Cis-platinum, Vincristine, Actinomycin-D, & Cyclophosphamide} and followed up for 4 months with partial remission.

Purpose: Giant cell tumor is the second most common benign neoplasm in upper extremity. Unlike usual chief complaint of painless mass, an atypical case with giant cell tumor presented a distinguishing characteristics of which accompany pain and tenderness and is histologically giant-cell free. Methods: A 31-year-old male patient complained of a rapid growing painful mass on the proximal phalanx of the left ring finger. Under microscopic operation, a $1.6{\times}1.3cm$ sized mass was found to be surrounded by areolar tissue and attached to a tendon sheath, encircling the digital nerve and artery. Diagnostic confirmation was assisted by positive finding in histologic immunohistochemical stain-CD68. Characteristic pathologic finding is an atypical distribution of spindle cells & histiocytes without giant cells in fascicular pattern. Results: Giant cell tumor was carefully removed under microscopic approach, while preserving digital nerve & artery. In postoperative 13th month, the patient presented with a 6mm of static two-point discrimination test, similar to that of the adjacent fingers. Conclusion: We report an atypical case with painful mass on tendon sheath, surrounding the digital nerve and artery that was diagnosed of giant cell tumor, but without giant cells on pathology. This case provides broader understanding of the giant cell tumor that should not only rely its typical findings of the painless mass and positive sign on H&E stain.

A 51 year-old male was admitted with the chief complaints of swallowing difficulty and pain on neck and upper chest for 2 months prior to admission: He was taken biopsy under esophagoscopy, and the result was squamous cell carcinoma. Preoperatively we studied the esophagogram and chest CT. On these, we found the main appreciable mass at midesophagus easily. But, we missed the upper cervical unexpected mass. So we performed the esophagectomy and lymph node dissection from upper clavicle level to the esophagogastric junction by thoracic approach as wide as possible, and cervical esophagostomy and feeding gastrostomy also. At that evening we reviewed the studied films in detail, and we found another mass lesion at C4-C6 level of cervical esophagus. We performed the 2nd operation e.g. cervical esophagectomy on next morning without hesitation. Between these two masses, there was almostly normally looking skip area grossly. The squamous cell carcinoma of the esophagus could be multicentric in character and may have skip area. But, we heard little reports until now. The two masses could be different in origin or be same probably by submucosal spreading. Anyway, it was an alarming case to the surgeon not to neglect the another possible lesions in squamous cell type. Postoperative course was uneventful, he took G-tube feeding with no problems on 7th postoperative day. Now he took the postoperative irradiation at out patient department.

Esophageal cancer is relatively uncommon except in isolated endemic areas, but it generally devastating to the patient. Usually, by the time the disease becomes clinically evident, it is incurable. The aim of treatment is then relegated to attempting to palliate the symptoms in the best possible manner with the least morbidity and mortality. Squamous cell carcinoma in by far the commonest type of malignancy involving the body of the esophagus, accounting for more than 95 percent of all esophageal malignancies. Because the tumor’s microscopic spread is much greater than its macroscopic extent, it is necessary to resect a sufficiently long segment of the esophagus. And second tumors may occur either in the esophagus as a manifestation of a field change or in other organs. Recently we had experienced a case with in situ carcinoma away from the invasive squamous cell carcinoma of the esophagus. A 58 year-old male was admitted with the chief complaint of swallowing difficulty for a month prior to admission. While we studied the esophagogram and chest CT, we found that the mass was protruded to the lumen of esophagus at the level of the 7th-9th thoracic vertebral columns. We performed esophagectomy with lymph node dissection and esophagogastrostomy by thoracic and abdominal approaches. The pathologic result showed separation of another in situ carcinoma away from the invasive squamous cell carcinoma of esophagus at the level of esophagogastric junctions. Postoperative course was uneventful. Now he is taking the postoperative irradiation at out patient department.
