Rabies is a fetal viral encephalitis to which all mammals, including man are susceptible. This virus, the genus of Rhabdovirus, is usually present in the saliva of infected animals and is transmitted by their bite. As a rule the virus enter the CNS by ascending along peripheral nervous system and extremely variable in extent. Negri bodies are appear in about 75% of cases. These bodies are eosinophilic, usually rounded inclusions and is located in the cystoplasm of the neurons, most frequently in the pyramidal neurons of the Hippocampus and the Purkinje cells of the cerebellum. We have experienced a case of canine rabies that showed Negri bodies in the Purkinje cells along with diffuse degenerative encephalitis and perivascular mononuclear cells infiltration. The Negri bodies were best demonstrated by Negri body staining although routine H-E staind was also useful. There inclusion bodies were located exclusively in the cytoplasm, and were found occasionally. Electron microscopic findings of the Negri bodies showed aggregates of bulletshaped nucleocapsids. We report a Negri body found in the brain of rabid dog with the light and electron microscopic findings.

PURPOSE: To examine the fate of muscle-derived stem cells (MDSC) after injection into different host conditions and provide an insight for their mechanism of action. MATERIALS AND METHODS: MDSCs differentiated in vitro towards the endothelial lineage and transfected with lentivirus tagged with green fluorescent protein (GFP) were injected into two animal models mimicking vascular diseases: hindlimb ischemia and carotid injury models. Injected cells were tracked at the site of injection and in remote organs by harvesting the respective tissues at different time intervals and performing immunofluorescent histological analyses. Stem cell survival was quantified at the site of injection for up to 4 weeks. RESULTS: MDSCs were successfully tagged with fluorescent material GFP and showed successful implantation into the respective injection sites. These cells showed a higher affinity to implant in blood vessel walls as shown by double fluorescent co-stain with CD31. Quantification of stem cell survival showed a time-dependent decrease from day 3 to 4 weeks (survival rate normalized against day 3 was 72.0% at 1 week, 26.8% at 2 weeks and 2.4% at 4 weeks). Stem cells were also fo und in distant organs, especially the kidneys and liver, which survived up to 4 weeks. CONCLUSION: MDSCs were successfully tracked in different vascular disease models, and their fate was assessed in terms of cell survival and distribution. Better understanding of the donor cell properties, including their interaction with the host conditions and their mechanism of action, are needed to enhance cell survival and achieve improved outcomes.

Bronchiolitis obliterans is a distinct pathologic entity, characterized by the accumulation of pigmented macrophages within respiratory bronchioles and adjacent to air spaces, and thickening of the peribronchial interstitium. It has been reported to be associated with viral infection, drug, toxic fume, bone marrow transplantation, and connective tissue disorders such as rheumatoid arthritis. The etiology of bronchiolitis obliterans in the post-renal transplantation state is not yet clear, although several possibilities such as drug toxicity, graft-versus-host disease or postinfectious condition have been postulated. We presented three patient who had bronchiolitis obliterans, as a complication following renal transplantation. Chest radiograph showed bilateral perihilar reticular infiltration or ground glass appearances that progressed to either diffuse alveolar consolidations or solitary nodule. The main finding in each lung biopsy was the presence of macrophages within respiratory bronchioles as well as in the neighboring alveolar ducts and alveoli. Alveolar septa in these areas often showed nonspecific thickening by fibrosis, mild chronic inflammatory cell infiltrate, and hyperplasia of alveolar lining cells and type II pneumocytes.

Various anatomical defects have been described in the surviving twin who had a stillborn, macerated monozygotic co-twin with Disseminated Intravascular Coargulation. The etiology is thought to be placental transfer of emboli or thromboplastic material through placental vascular anastomoses. We experienced a case of monozygotic twin with deceased co-twin at 30 weeks of gestation and confirmed to have antenatal periventricular germinal matrix and intraventricular hemorrhage, multicystic periventricular leukomalacia and diffuse encephalomalacia by neurosonography on first day of life despite of no clinical evidence of brain damage. The pathologic findings of placenta revealed infarct with massive fibrin deposition. A brief review of related literature is presented.

A retrospective study of 274 patients who presented with constipation was done. The following results were obtained by recording colonic transit time. The male to female ratio was 72 : 197, and most patients were in their third and fifth decade, each age group accounting for 21% of total number. Associated symptoms were anal discomfort(33%), abdominal discomfort (25%), hematochezia (23%), reduced stool caliber (11%), and tenesmus (8%). As a result, 223 patients had normal transit time and 51 patients had abnormal transit time. Eighty-six patients with normal transit time and 51 patients with abnormal transit time underwent barium enema or colonoscopic examination. Abnormal lesions such as polyps and diverticulums were found in 10 patients with normal transit time and 7 patients with abnormal transit time. Therefore barium enema and colonoscopic examination in the patients with abnormal transit time were meaningful (P=0.024). Eighteen out of 25 patients with normal transit time and 8 (67%) of 12 patients with abnormal transit time showed abnormal defecogram results. The rectocele was the most frequent cause of abnormality in defecogram. Abnormal anal manometry results were obtained in 5 (22%) of 23 patients with normal transit time and 3 (50%) of 6 patients with abnormal transit time. Three types were classified in the patients with abnormal transit time. With type II patients, anal manometry findings were normal and 2 patients showed abnormal results in defecogram. With type III patients, 5 (43%) of 12 patients showed abnormal results in defecogram and 3 (50%) of 6 patients had abnormal anal manometry findings. Conclusively, if abnormal transit time is found in the patients with chronic consipation, further evaluations such as barium enema or colonoscopic examination are necessary. And even in the patients without any abnormality in transit time, selected performance of defecogram and anal manometry depending on clinical symptoms are preferable.

BACKGROUND : Borame hospital nuns geriatric wards with 120 beds (40 beds for patients in Dept. of Internal Medicine, 40 for patients in Dept. of Orthopedics 40 for patients in Dept. of Neurology) from December 1996. We studied clinical characteristics of admissions to acute geriatric wards in Borame hospital in order to assess current status of geriatric wards in Korea. METHODS : 334 patients admitted from December 1996 to May 1997 were studied. By reviewing clinical records of these patients, we studied clinical characteristics of patients in geriatric wards retrospectively. RESULTS : 1) Age distribution: 8.6% of patients were over 85 years old. 16.4% of patients were between age of 80-84. 20.0% between 75-79, 31.3% between 70-74, 26.3% between 65-69, respectively. 2) Disease: 43% of patients have single disease, 67% of patients have multiple disease(23% of patients with 2 disease, 25% with 3 disease, 6% with 4 disease, 3% with over 5 disease respectively). 3) Mortality rate :Total mortality rates were 4.3% with 6.1% of patients in Internal medicine, 3.2% of patients in Neurology. These rates were much higher compared with mortality rates of 2.4% in general wards but similar to those (6.7%) in general wards in Internal medicine. 4) Causes of admission: Malignancies were most common causes of admissions in males, and then cerebrovascular diseases, infectious diseases, musculoskeletal diseases, in order. Musculoskeletal diseases were most common causes, and then diabetes mellitus, infectious diseases, cerebrovascular diseases. CONCLUSION : The elderly patients tend to have multiple diseases, longer hospital stays and higher mortality rates compared with younger patients in general wards. but differences of hospital stays and mortality rates are less than be expected.

Jin Sub AHN ; Young Kyung PARK
Korean Journal of Urology 1992;33(1):58-64
A total or 56 patients who underwent TUR-BT for superficial (stages O and A) bladder tumors received various chemoprophylactic treatment to prevent recurrence. 16 patients underwent resection only (Group I). Of the 56 patients treated with chemoprophylactic agents 18 patients were given thio-tepa at weekly interval for 8 weeks (Group 2). 20 patients were given adriamycin. weekly one time for 6 weeks (Group 3). 16 patients were given mitomycin C, weekly one time for 8 weeks (Group 4). All chemoprophylactic groups were followed by monthly one time for 1 year and the dosages of the used agents (thio-tepa, adriamycin and mitomycin C) were 60 mg/l dosage, 50 mg/l dosage and 30 ml/l dosage, respectively. During follow-up period (mean duration; 19.8-25. 2 months), 1umor recurred 56.2 % of group 1 patients, 27.7 % of group 2 patients, 25.0% of group 3 patients, 18.9 % of group 4 patients and 22.2% of total patients. Therefore three drugs were effective to decrease the recurrence rate of superficial bladder tumor and no significant differences in recurrence rate were noticed among drugs. Toxicity of the three agents were negligibly minimal except 2 patients who developed severe gross hematuria after adriamycin instillation.

BACKGROUND: It is well known that ischemic preconditioning protects the heart against infarction or arrhythmias from a subsequent ischemic injury. Recent laboratory data indicate that the adenosine during the ischemic period may trigger protection via A1 or A3 adenosine receptor and also protein kinase C(PKC) plays a central role. This study was designed to determine the role of adenosine receptor subtypes and PKC in the preconditioning protection. METHODS: All cat heart groups were subjected to 40min ischemia and 30min reperfusion. The preconditioning protocol consists of 4min ischemia and then 10min of reperfusion 4 times. The effects of ischemic preconditioning, nonselective adenosine receptor blocker(SPT), an A1 specific antagonist(DPCPX) and protein kinase C inhibitor(Polymyxin B), on ischemic preconditioning were determined by infarction size. There were 5 groups : (1) control group (Group 1, n=10)(2) Ischemic preconditioned group(Group 2, n=9)(3) DPCPX pretreatment group(Group 3, n=6)(4) SPT preteatment group(Group 3, n=6)(5) Polymyxin B pretreatment group(Group 5, n=6). SPT and DPCPX were given intravenously 5 min before ischemic preconditioning. Polymyxin B was administered to cats for 30min during ischemic preconditioning period. RESULTS: Ischemic preconditioning only or pretreatment with DPCPX prior to preconditioning demonstrated a significant reduction in infarct size(22.6+/-1.5, 25.4+/-0.9% infarction of the risk zone, respectively, p<0.05) with respect to control, SPT-pretreatment, and polymyxin B-pretreatment groups(44.0+/-1.7, 43.0+/-2.0 and 40.3+/-0.4% infarction of the risk zone, respectively). CONCLUSIONS: Ischemic preconditioning protects heart from subsequent ischemia. Protection was blocked by SPT and protein kinase C inhibitor(polymyxin B), but not by A1 antagonist DPCPX. The cardioprotective effects by ischemic preconditioning in the in vivo cat heart appear to be dependent on A3 adenosine receptors and activation of protein kinase C.
