  • Objectives : Hippocampus, a region of temporal lobe, plays an important role in the pathogenic mechanisms of brain diseases such as Alzheimer's disease, depression and temporal lobe epilepsy. This research is designed to investigate hippocampal changes after acupuncture stimulation at Shinmun(HT7) using 2-dimensional gel electrophoresis(2-DE). Methods : On postnatal-day 15, rat pups were randomly devided into Normal(NOR) or HT7 group. All of Pups kept with their mothers for 7 days, but pups in HT7 group received acupuncture stimulation at HT7 daily. On postnatal-day 21, hippocampus of each rat pup was dissceted 30 minutes after last acupuncture stimulation and the protein expressions were investigated using 2-DE. Results : After acupuncture stimulation at HT7, expression of 20 proteins were significantly increased. Succinate semialdehyde dehydrogenase, glyceraldehyde-3-phosphate dehydrogenase-like, transketolase, aconitate hydratase and phosphoglucomutase-1 were related to glucose methabolism. Eukaryotic initiation factor(eIF) 4A-II, eIF 4A-III, mitochondrial Tu translation elongation factor and chain A of crystal structure of the 70-Kda heat shock cognate protein involve in the protein synthesis in ribosome. Tubulin ${\beta}$-4 chain, tubulin T ${\beta}$-15 and tubulin ${\alpha}$-1B chain comprise cytoskeleton. Glutathione S-transferase(GST) ${\omega}$-1, GST P and GST Yb-3 can reduce oxidative stress. ${\beta}$-soluble N-ethylmaleimide-sensitive fusion protein attachment protein is required for vesicular transport between the endoplasmic reticulum and the Golgi apparatus, glycerol-3-phosphate dehydrogenase plays a major role in lipid biosynthesis, creatine kinase U-type catalyses the conversion of creatine and consumes adenosine triphosphate to create phosphocreatine and adenosine diphosphate. Platelet-activating factor acetylhydrolase IB subunit alpha and voltage depedent anion-selective channel protein 2 were also increased. Conclusions : The results suggest that acupuncture stimulation at HT7 may enhance glucose and lipid metabolism, protein synthesis, cytoskeletal substance and anti-oxidative stress in hippocampus.

  • Systemic Lupus Erythematosus(SLE) is a autoimmune disease characterized by combined symtoms of malar rash, discoid rash, neuropsychiatric disorder, renal disorder, hematologic disorder, photosensitivity immunologic disorder, oral ulcer, anti-nuclear antibody, arthritis, pleuritis and pericarditis, etc. Multiple genetic or environmental causes are supposed to facilitate antiboby production to autoantigen such as ds-DNA, histone, phospholipid, red blood cell, platelet, etc. And defective complementary system fail to remove autoantigen-antibody complex, which deposit in multiple organs and result in inflammatory damages. SLE does not correctly correspond to any specific category of oriental medicine. But, accoring to previous reports, it can be controlled by herb medications used differently patients-to-patients. So we are to report this one SLE case being successfully controlled by classic corticosteroids with herb medications based on oriental diffrential diagnosis of symptoms and signs.

  • This is a retrospective study of 42 pregnancies from 33 women with prosthetic heart valves who were on anticoagulation regimen prior to or during their pregnancy. Material and Method: Of the 17 women with bioprosthesis, 15 had 21 pregnancies following cessation of the anticoagulation therapy which resulted in the delivery of 20 healthy babies and 1 abortion. Remaining 2 had 3 pregnancies maintained with heparin, resulting in 2 healthy babies and 1 spontaneous abortion. Result: Among 16 women with mechanical heart valves, there were 7 pregnancies during which warfarin was used and this was associated with 4 fetal wastages(2 therapeutic abortion, 1 spontaneous abortion and 1 stillbirth with cerebral hemorrhage). However, in pregnancies where heparin was used, there was no fetal wastage. A patient who did not take anticoagulant for the first trimester and took warfarin for the remaining period and a patient who did not take anticoagulant during pregnancy delivered normal babies. There was an other fetal wastage in a patient on anti-platelet therapy for the first trimester and warfarin therapy for the remaining periods. There was 1 minor petechial complication in a heparin administered group. Conclusion: The study indicates that woman with bioprosthetic heart valves can go through pregnancy without undue risks or complications. On the other hand, the use of warfarin during pregnancy in women with mechanical heart valves, was shown to be associated with unacceptable high risk for the fetus. However, in the same group of women, judicious use of heparin during pregnancy was accompanied by a much reduced risk. The safety and adequate therapeutic range of heparin usage under such circumstances are subject to further studies.

  • A total and consecutive 156 patients have undergone cardiac valve surgery including 13 closed mitral commissurotomy, 13 open mitral commissurotomy, one mitral annuloplasty, 75 mitral valve replacement, one aortic annuloplasty, 24 aortic valve replacement, 3 tricuspid valve replacement, 25 double valve replacement and one triple valve replacement. 155 prosthetic valves were replaced in a period between September 1976 and August 1985. There were 68 males and 88 females with age range from 8 to 69 yrs [mean 36.5 yr]. Out of replaced valves, 61 was tissue valve including 54 Carpentier-Edwards, and 4 was mechanical valves including 74 St. Jude Medical, and the position replaced was 101 valves for mitral, 46 for aortic and 8 for tricuspid. Single valve replacement in 102 cases, double valve replacement in 25 cases [17 for AVR+MVR, and 8 for MVR+TVR], and only one case was noted in the triple valve replacement. Early mortality within 30 days after operation was noted in 11 cases [7%]; 7 after MVR, 2 after DVR, and each one after open mitral commissurotomy and mitral annuloplasty. Cause of death was valve thrombus, cerebral air embolism, low output syndrome, uncontrollable arrhythmia, parapneumonic sepsis, acute cardiac tamponade and left atrial rupture. 7 late deaths were noted during the follow-up period from 1 to 104 months [average 48 month]; three due to valve and left atrial thrombus formation, two due to CVA from overdose of warfarin, and each one due to congestive heart failure and chronic constrictive pericarditis, Anticoagulants after prosthetic valve replacement were maintained with warfarin, dipyridamole and aspirin to the level of around 50% of normal prothrombin time in 79 cases, and Ticlopidine with aspirin in 47 cases to compare the result of each group. There were 11 major thromboembolic episodes including 3 deaths in the warfarin group. Two cases of CVA due to overdose of warfarin was noted in the warfarin group. In the ticlopidine group, there was only one left atrial thrombus confirmed at the time of autopsy. Among the survived 138 cases, nearly all cases[136 cases] were included in NYHA functional class I and II during the follow-up period. In conclusion, surgical treatment of the cardiac valve disease in 156 clinical cases revealed excellent result with acceptable operative risk and late mortality. Prevention of thrombus formation with anti-platelet aggregator Ticlopidine has better result than warfarin group presently with no specific side effect such as bleeding or gastrointestinal trouble.

  • Objective : The spot sign is related with the risk of hematoma expansion in spontaneous intracerebral hemorrhage (ICH). However, not all spot sign positive patients undergo hematoma expansion. Thus, the present study investigates the specific factors enhancing the spot sign positivity in predicting hematoma expansion. Methods : We retrospectively studied 316 consecutive patients who presented between March 2009 to March 2011 with primary ICH and whose initial computed tomography brain angiography (CTA) was performed at our Emergency Department. Of these patients, 47 primary ICH patients presented spot signs in their CTA. We classified these 47 patients into two groups based on the presence of hematoma expansion then analyzed them with the following factors : gender, age, initial systolic blood pressure, history of anti-platelet therapy, volume and location of hematoma, time interval from symptom onset to initial CTA, spot sign number, axial dimension, and Hounsfield Unit (HU) of spot signs. Results : Of the 47 spot sign positive patients, hematoma expansion occurred in 26 patients (55.3%) while the remaining 21 (44.7%) showed no expansion. The time intervals from symptom onset to initial CTA were $2.42{\pm}1.24$ hours and $3.69{\pm}2.57$ hours for expansion and no expansion, respectively (p=0.031). The HU of spot signs were $192.12{\pm}45.97$ and $151.10{\pm}25.14$ for expansion and no expansion, respectively (p=0.001). Conclusions : The conditions of shorter time from symptom onset to initial CTA and higher HU of spot signs are the emphasizing factors for predicting hematoma expansion in spot sign positive patients.

  • Objectives: This study aimed to investigate the preventive effect of red ginseng (RG) on 5-fluorouracil (5-FU)-induced side effects focusing on myelosuppression. Methods: Rats (n = 50) were divided into five groups, nave, control (ip, 5-FU injection of 150 mg/kg), and RG pre-treatment (po, 25, 50 and 100 mg/kg for 5 days before 5-FU injection). On the $7^{th}$ day after 5-FU injection, we evaluated the effects using peripheral hematological parameters, colony-forming assay, cytokine levels and histopathological finding. Results: The peripheral white blood cell and the differential count were dramatically suppressed by 5-FU, while RG (50 and 100 mg/kg) treatment significantly improved total white blood cell, neutrophil, lymphocyte and platelet counts. Also, RG (100 mg/kg) pre-treatment significantly increased the number of CFU-GM colony compared with the control group. RG pre-treatment also ameliorated the histopathological damage in bone marrow, spleen, stomach and small intestine tissue. Conclusions: These results demonstrate that Korean RG has preventive effects against 5-FU-induced myelotoxicity and gastrointestinal damage.

  • Hepatic fibrosis represents the main complication of most chronic liver disorders and, regardless of its etiology, is characterized by excessive deposition of extracellular matrix components. In this study, we examined that 1-O-Hexyl-2,3,5-Trimethylhydroquinone (HTHQ), a potent anti-oxidative agent, could prevent experimental hepatic fibrosis induced by dimethylnitrosamine (DMN) in male SD rats. Except for vehicle control group, other groups were induced hepatic fibrosis by intraperitoneal injection with DMN (10 mg/ml/kg) on 3 consecutive days weekly for 4 weeks. During the same 4 weeks, control and DMN groups were given vehicle and HTHQ 50, 100 and 200 groups were orally administered HTHQ (50, 100, 200 mg/kg respectively). In HTHQ 100 and 200 groups, relative liver weight and serum chemistry level improved significantly. HTHQ reduced hydroxyproline (p < 0.05) and malondialdehyde (p < 0.05) level in the liver. Histopathological examination of H&E, Masson's trichrome stain showed the reduced fibrotic septa in HTHQ 100 and 200 groups. HTHQ administration showed reduced mRNA level of PDGF (Platelet-derived growth factor), $\alpha$-SMA ($\alpha$-smooth muscle actin) and TGF-$\beta$ (transforming growth factor-$\beta$) than DMN-induced hepetic fibrosis animals in the liver tissue. In this study, we showed that HTHQ improves against DMN-induced liver fibrosis in male SD rats.

  • Since 1931, sporadic reports have appeared noting an apparent association between hyperthyroidism and idiopathic thrombocytopenic purpura. Recent various studies suggested that these two diseases may share a similar immunologic background, but the the exact mechanism is still a matter of speculation. This 22-year old female patient visisted this hospital because of general weakness and purpura of legs for 2 months. The laboratory findings were compatible with Graves' disease associated with idiopathic thrombocytopenic purpura. The palatclet count was 16000/$mm^3$, hemoglobulin was 10.9g/dl and MCV was 60.1tL. T3 was 490.53ng/dL, T4 was 24ug/dL and free T4 was 5.66ng/dL. Antiplatelet antibody and anti-microsomal antibody were positive. The bone marrow findings were compatible with tron deficiency anemia and idiopathic thrombocytopenic purpura. The thyroid biopsy showed adenomatous goiter. She was administered with propyl thiouracil, Beta-blocker, iron and prednisolon. On the 10th hospital day, platelet count was 184000/$mm^3$, hemoglobulin was 12.0gm/dL and MCV was 67.5fL. On the 20th hospital day, T4 was 10.35ug/dL and free T4 was 2.30ng/dL. Therefore she was discharged and followed up.

  • Gamma-aminobutyric acid (GABA) is a non-protein amino acid. It is well known for its role as an inhibitory neurotransmitter of developing and operating nervous systems in brains. In this study, a novel function of GABA in the healing process of cutaneous wounds was presented regarding anti-inflammation and fibroblast cell proliferation. The cell proliferation activity of GABA was verified through an MTT assay using murine fibroblast NIH3T3 cells. It was observed that GABA significantly inhibited the mRNA expression of iNOS, IL-$1{\beta}$, and TNF-${\alpha}$ in LPS-stimulated RAW 264.7 cells. To evaluate in vivo activity of GABA in wound healing, excisional open wounds were made on the dorsal sides of Sprague-Dawley rats under anesthesia, and the healing of the wounds was apparently assessed. The molecular aspects of the healing process were also investigated by hematoxylineosin staining of the healed skin, displaying the degrees of re-epithelialization and linear alignment of the granulation tissue, and immunostaining and RT-PCR analyses of fibroblast growth factor and platelet-derived growth factor, implying extracellular matrix synthesis and remodeling of the skin. The GABA treatment was effective to accelerate the healing process by suppressing inflammation and stimulating re-epithelialization, compared with the epidermal growth factor treatment. The healing effect of GABA was remarkable at the early stage of wound healing, which resulted in significant reduction of the whole healing period.

  • Background : Although chronic non-bacterial prostatitis is increasing, it is hard to treat effectively. In western medicine, antimicrobials drug, ${\alpha}$-adreno-ceptor antagonists, anti-inflammatory drugs, tricyclic antidepressants and anticholinergic agents are used commonly, but chronic prostatitis/chronic pelvic pain syndromes is confusing and frustrating for urologist. IDS(Indongsoyeom-bang) is used in treatment of chronic prostatitis/chronic pelvic pain syndromes. And it is reported that GLS(Gleditsiae spina) and TOF(Toosendan fructus) components of IDS have significant effect on protection of the glandular epithelial cells. Objective : In this study was conducted to investigate the therapeutic effects and action machanism of IDS in the rat model of non-bacterial prostatitis induced by castration and testosterone treatment. Methods : We observed six experimental objects of normal group, control group, testosterone group, and IDS 50 mg/kg, 200mg/kg, 400mg/kg group. Rats were treated with 17 ${\beta}$-estradiol after castration for induction of experimental non-bacterial prostatitis, which is similar to human chronic prostatitis in histophatological profiles. IDS and testosterone were administered as an experimental specimen and a positive control, respectively. The prostates were evaluated by histological parameters including the epithelial score and epithelio-stromal ratio for glandular damage. Also, the prostates were observed by Hematological alterations of WBC, RBC, hemoglobin and platelet. Results : While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation, the rats treated with IDS-50 showed a diminished range of the tissue damage. Epithelial score was improved in IDS than that of the control. The epithelio-stromal ratio was lower in IDS when compared to that of the control. Also, the examination of bloods were not observed hematological change. Conclusion : These finding suggests that IDS may protects the glandular epithelial cells. We concluded that IDS could be a useful remedy agent for treating chronic non-bacterial prostatitis.
