To evaluate the degree of competitive exclusion against Salmonella gallinarum(S. gallinarum) of Salmonella enteritidis(S. enteritidis) infected chickens, fifty-six, 4-week old Hyline layer suspected of S. enteritidis infection were challenged with S. gallinarum. All chickens were tested for S. enteritidis isolation using cloacal swabs and serum plate agglutination test using S. enteritidis Ag. before challenge and classified into four groups(SE isolated, SE nonisolated, SE seropositive and SE seronegative). None of the SE isolated and the SE seropositive groups died after challenge and the average weight gains were 245.5g and 254.6g, respectively. But in the SE nonisolated and the SE seronegative groups, mortality was 18.2% and 20.6% and the average weight gains were 150.1g and 111.2g. The incidence of reisolation of S. gallinarum of the SE isolated and the SE seropositive groups were 41.7% and 47.6% from liver, 33.3% and 47.6% from spleen and 8.3% and 14.3% from cecum, respectively, and the SE nonisolated and the SE seronegative group were 63.6% and 64.7% from liver, 84.1% and 88.2% from spleen and 47.7% and 52.9% from cecum. The serological response of the SE isolated and the SE seropositive groups hardly changed from 75.0 and 81.8% before challenge to 75.0 and 85.7% after. But, the other two groups were found to be significantly higher after challenge and increased from 0 and 18.2% to 100%. Consequently, S. enteritidis preinfected chickens were found to be significant different in terms of mortality, weight gain, reisolation of S. gallinarum and serological response compared to noninfected chickens. Moreover, our study shows that S. enteritidis infected chickens appear strong competitive exclusion against the colonization of S. gallinarum.

Reversible splenial lesion syndrome can be caused by viral infection. Rubella generally occurs in childhood, and it is rarely accompanied by neurological complications in adulthood. A 35-year-old man visited our hospital due to conjunctival injection, mild fever, and headache 3 days after experiencing skin rash. Brain magnetic resonance imaging (MRI) revealed distinct lesions involving white matter in the splenium of the corpus callosum approximately 3 days following the onset of symptoms. Enzyme immunoassay performed on serum and CSF samples was positive for rubella virus IgM. A follow-up brain MRI was performed 24 days after the onset of symptoms, and reduced lesion size with decreased signals were observed on diffusion weighted image. This case showed that rubella infection can result in reversible splenial lesion accompanied by only mild neurological symptoms.

OBJECTIVE: To analyze the factors affecting on the level of the quality of life of stroke patients and their family caregivers. METHOD: Among the stroke patients receiving rehabilitation treatment at forty three out patient clinic in university hospitals, 289 stroke patients who scored over 24 out of 30 points in MMSE-K and their family caregivers were interviewed using questionnaires. RESULTS: The main contributory variable on the quality of life (QOL) of caregivers was the socio-demographic factor and QOL of caregivers was improved with decreasing age, the higher level of education, the less burden of care and the better condition of patient. High correlation coefficients were showed between QOL of stroke patients and ADL, QOL of caregivers and burden of care, and the burden of care and the neurological impairment. The main contributory variable on the QOL of stroke patients was clinical characteristics factor and QOL of stroke patients was improved with increasing the levels of cognitive function and ADL performance, decreasing the level of neurological impairment, the more social support from friends and the less burden of caregivers. CONCLUSION: In order to improve the QOL of stroke patients, not only patients' physical factors, but psychological factors, socio-demographic factors and QOL of caregivers should also be considered.

Ossifications of the ligamentum flavum(OLF) and the posterior longitudinal ligament(OPLL) are uncommon clinical entities as a cause of the progressive compression myelopathy or radiculopathy. Although there are considerable literatures concerning OPLL or OLF in cervical and thoracic spine, there are only a few references about OPLL or OLF in the lumbar spine. OLF and OPLL have been reported that they may lead to severe complication only with a minor trauma or even without trauma, such as paraplegia. The authors have experienced 2 cases of OLF accompanied by OPLL In the lumbar spine, who were treated with decompressive laminectomy and excision of ossified ligaments. For its rarity of OLF and OPLL in the lumbar region, we report here with review of literature.

Rhino-orbito-cerebral muconnycosis is an uncommon fatal fringal infection, almost exclusively seen in diabetic or other itnmunocompromised patients. Recurrent transient ischemic attacks(TIAs) as initial presenting sign of rhino-orbito-cerebral mycormycosis has not been reported to our knowledge. We report a patient with muconnycosis unusually presenting with recurrent TIAs, followed by central retinal artery occlusion, multiple cranial nerve palsies, and then cerebral infarction in the territory of middle cerebral artery.

Clear cell sarcoma of kidney(CCSK) is a rare pediatric neoplasm characterized by a predominating component of clear cells, a predilection for metastases to bone, and a poor prognosis. The incidence of CCSK peaks during the 2nd year of life and adult cases are very rare. We report a case of CCSK encountered in the right kidney of a 39-year-old man. Grossly, it was a lobulated mass showing infiltrative margin, measured 7x5.5x5cm and had a homogeneous gray-tan color with a soft, fish-flesh consistency. Microscopically, about half of the tumor revealed the classic pattern of CCSK, having tumor cell cords or nests separated by the characteristic alveolar capillary networks. The tumor cells had clear pale cytoplasm, bland looking round nuclei and inconspicuous nucleoli. The other half showed the epithelioid-trabecular pattern forming pseudorosette or cord-like structures. Immunohistochemically, there was only a focal positive reaction to vimentin. Ultrastructurally, the tumor cells showed the primitive nephrogenic mesenchymal differentiation such as electron lucent cytoplasm, a small amount of organelles, scanty heterochromatin, inconspicuous nucleoli, and a lack of flocculant basal lamina material around the cytoplasmic membrane. We consider that this is a case of CCSK occuring in the oldest patient ever reported, confirmed by both immunohistochemistry and electron microscopy.

As the use computed tomographic (CT) scanning spread, the diagnosis of blowout fractures of the medial orbital wall increased. Now, the diagnosis of blowout fracture in the medial wall are not uncommon. Conventionally, the surgery of blowout fractures in medial orbital wall was performed by the various approach with external incision. The conventional method had seveal possible disadvantages, including an external scar, incomplete reduction, increased mobidity rate and general anesthesia. Recently, endoscopic reconstruction of the medial orbital wall has provided good functional and cosmetic results. We performed endoscopic transnasal reduction surgery without external incision in 12 cases of medial blowout fracture under local anesthesia. The fractured bony fragments were removed after the intranasal ethmoidectomy and the entrapped medial rectus was released. And then a sheet of silicone late or uncinate process were placed on the fracture site. For the maintain of the position of fractured wall, Merocel packing or urinary ballon catheter were used in orbital fracture site for 1-3 weeks. There were no specific complications related to this procedure. Result of the surgery in all cases were satisfactory. In this article, we discussed the surgical procedure, the benifit of the transnasal endoscopic approach, the indications for surgery, and possible comlications.

Recently, the detection of traumatic intracerebral hematoma has been greatly expedited by the advent of computed tomography. However, traumatic basal ganglia hemorrhage(TBGH) in child have remained rare. The authors obtained following results with analysis of clinical features and outcome in 8 cases of child's TBGH who had been treated at the department of neurosurgery, chonnam university hospital from January 1984 to December 1986. 1) Age distribution was ranged from 3 to 9 years with an average age 5.1 years and 5 were males and 3 were females. 2) Blow of site of the head were right frontal 3, left frontal 3, right parietal 1 and right temporal 1. However, hematoma in the basal ganglia occurred 6 in the left and 2 in the right. 3) On admission, the consciousness level appeared 2 cases in drowsy state(GCS 13), 3 cases in stuporous state(GCS 8,9) and 3 cases in semicomcatose state(GCS 5,7). 4) CT findings of TBGH were classified into 3 types; Type I; spotty type, Type II; moderate type and Type III : massive type. The number of patients was 4 in type I, 2 in type II and 2 in type III. 5) Neurological examination revealed contralateral hemiparesis to the hematoma in all cases(8), facial nerve palsy in 3 cases, motor aphasia in 4 cases and decerebrate rigidity in 2 cases. 6) Of all cases (8), conservative treatment were done in 5 and surgical treatment in 3. As regards the outcome of all cases (8), showed good recovery in 3, moderate disabilety in 2 and death in 3. It was concluded that the first regimen to be chosen in the management of TBGH in child was medical treatment. The patient of moderately disturbed conseionsness would be successfully managed by conservative treatment. The indication for surgery should be restricted to such cases in which the consciouness status were getting worse in spite of active conservative treatment.
