  • The purpose of this research was to investigate the effect of Yonggak-san (YGS) on the immune reaction and apoptosis of leukemia cells. Administration of YGS(500 mg/kg) enhanced proliferation of splenocytes, thymocytes and mesenteric lymph node cells, and also YGS accelerated subpopulation of splenic Band T, thymic T and mesenteric lymph node-T lymphocytes, especially significantly increased CD4+-TH cells in BALB/c mice. YGS accelerated phagocytic activity and production of nitric oxide in peritoneal macrophages. YGS induced apoptosis of transplanted-L1210 cells in vivo, increased apoptotic cell death of cultured-L1210 and/or Molt4 human leukemia cells, decreased of mitochondrial transmembrane potential of both cells in vitro. These results suggest that YGS have an immune-regulatory effect and anti-cancer property.

  • The purpose of this research was to investigate the effect of Eunkyo-San(EKS) on the immune system. Administration of EKS(500 mg/kg) enhanced viability of splenocytes and thymocytes in BALB/c mice, and also EKS increased of splenic B, T lymphocytes and thymic T lymphocytes, significantly increased CD4 positive TH cells. EKS markedly enhanced the production of -interferon in mice serum. EKS accelerated the production of nitric oxide in peritoneal macrophages. These results suggest that EKS have an immune-enhancing activity.

  • Ectopic cervical thymic tissue is rarely reported in medical literature, but it should be included in the differential diagnosis of neck masses, especially in children. It occurs in the line of descent of the thymus from the angle of the mandible to the superior mediastinum. A preoperative diagnosis is seldom considered and is often misdiagnosed as a possible tumor or a lymph node. We present a case of a 2-month-old infant with an asymptomatic enlarging right neck mass. Patient underwent complete excision of the mass.

  • We report a case of 36-year-old woman with myasthenia gravis (MG) combined with mediastinal leiomyosarcoma (LMS) and Stevens-Johnson syndrome (SJS). She was admitted to ICU with the symptoms of acute onset headache, diplopia, ptosis, dysphagia, general weakness, and respiratory difficulty for several days. Physical examination revealed tachypnea, decreased breath sounds and dullness to percussion in right lower chest. Neurologic examination showed ptosis, diplopia, decreased gag reflexes, and generalized proximal weakness. Laboratory studies revealed increased serum acetylcholine receptor antibodies and positive Tensilon test. Chest CT showed a huge mass in the right middle mediastium but no evidence of thymic enlargement. Mediastinal LMS was diagnosed by ultrasound-guided needle biopsy. The myasthenic symptoms were fluctuated in spite og intravenous immunoglobulin, plasmapheresis, and corticosteroid. During therapy, SJS developed. She died 4 months after the onset of the myasthenic symptoms despite the chemotherapy for LMS.

  • The purpose of this research was to investigate the immunoregulatory effect, apoptosis of L 1210 leukemia cells of Comus officinalis Sieb.et Zucc. The proliferation of cultured splenocytes and thymocytes were enhanced by the addition of SSY. Splenic, thymic and mesenteric lymph node-T lymphocytes, especially TH cells was significantly increased in SSY-administered (p.o. for 7 days) mice. SSY treatment induced the apoptosis of L1210 mouse leukemia cells. In addition, SSY accelerated the phagocytic activity and nitric oxide production in peritoneal macrophages. These results suggest that SSY have an immuno-regulatory property and anti-cancer effect.

  • The purpose of this research was to investigate the effects of Chungjokupye-tang(CJKPT) on the anti-carcinogenic action. The cell viability of mouse spienocytes and thymocytes were enhanced by the addition of CJKPT. CJKPT were increased of splenic and thymic T lymphocytes, such as T/sub H/ cells were markedly increased by the treatment of CJKPT in vivo. CJKPT treatment induced the apoptotic cell death of Jurkat and HL60 leukemia cells. CJKPT reduced mitochondrial transmembrane potential and increased the expression of ICE, c-myc and p53 gene in Molt-4cells dose dependant manner. These results suggest that CJKPT have an anti-carcinogenic action via immunoregulatory mechanism.

  • internal thoracic artery is used in myocardial revascularization because of many advantages. However, it may not be appropriate in the usual extrapleural or intrapleural route, because it can be easily displaced and injured due to the slender and weak characteristics. We introduce here, a simple technique of repositioning the skeletonized left internal thoracic artery in a stable and straight course by creating a tunnel between the left lateral pericardium and thymic tissue.

  • On day 2 after treatment of Lewis rat with 25mg of hydrocortisone, the cell number in the thymus was reduced to less than 10% of the matched control. By day 12 after hydrocortisone treatment the thymic cell population was recovered almost its original value and on day 24 after treatment the number of thymocytes was equivalent to that of normal thymocytes. The density distribution profile of hydrocortisone treated rats as compared with normal rats showed a marked decrease in the denser fraction D while the lighter fractions. (A plus B, and C) showed a considerable proportional increase. The proportion of dead cells in thymus suspension from hydrocortisone treated rats was higher than that from their normal counterparts. On separation, the dead cells accumulated selectively in the pellet and A fraction. The response of the thymocytes from hydrocortisone treated rats to PHA was increased compared to that from normal rats. Among the subpopulations, D fraction, which was relatively unresponsive in normal rats, showed a marked increase in PHA response and C fraction showed some increase in the response.

  • The purpose of this research was to investigate the effect of Cheongsimondam-tang(CSODT) on the activity of immune cell and anti-carcinogenic effect of mouse leukemia cell. The addition of CSODT(1 ㎍/ml) enhanced the proliferation of cultured-splenocytes and thymocytes. And also administration of CSODT(500 ㎍/kg) accelerated subpopulation of splenic and thymic T lymphocytes especially CD4/sup +/-T/sub H/ cells in BALB/c mice. CSODT treatment decreased cell proliferation and increased apoptotic cell death of cultured-L1210 leukemia cells, and induced apoptosis in addition to decreased mitochondrial transmembrane potential (ΔΨm) of transplanted-L1210 cells in vivo. These results suggest that CSODT have a cellular immuno-regulatory effect and anti-cancer property action.

  • The purpose of this research was to investigate the effects of Calendula officinalis extract (CE) on the activation of murine lymphocytes and macrophages. CE was administered p.o. once a day for 7 days at the concentration of 500 mg/kg. The administration of CE increased the viability of thymocytes, but decreased the viability of splenocytes. Also, CE increased the viability of thymocytes and splenocytes at the concentration of $5{\mu}g$/ml in vitro. The administration of CE did not affect the population of thymic $CD4^+$/$CD8^+$ cells and splenic $CD4^+$/$CD8^+$ cells. Furthermore, the administration of CE enhanced the phagocytic activity of peritoneal macrophages, but decreased the phagocytic activity in vitro. CE decreased the production of nitric oxide from peritoneal macrophages in vivo and in vitro system. These results suggest that CE enhance of cell viability by a direct influence on thymocytes and phagocytic activity by an indirect influence on peritoneal macrophages.
