Two cases of subdural tension pneumocephalus were introduced after posterior fossa surgery in the sitting position. The possible mechanism for entry of air into the subdural space is explained as the fluid pours out air bubbles to the top of the container. All of two cases manifested generalized seizure at recovery room and were diagnosed with plain skull series and computed tomogram. Subdural air evacuated patient fail to recover as expected, following posterior fossa surgery in sitting position.

PURPOSE: Tumor necrosis factor (TNF)-alpha and eosinophilic inflammation have their role in asthma, but there were no studies on respiratory syncytial virus (RSV) bronchiolitis. The aim of our study was to investigate whether TNF-alpha has a role in eosinophilic inflammation of lower respiratory tract infections with RSV and has the correlation with other cytokines. METHODS: Fifty children with first RSV bronchiolitis (RSV group) and 18 healthy children without any respiratory symptom and sign (control group) were enrolled. Clinical data, such as eosinophil-derived neurotoxin (EDN), eosinophil cationic protein (ECP), were analyzed. We measured interleukin (IL)-5, IL-8, TNF-alpha, granulocyte macrophage-colony stimulating factor (GM-CSF), interferon (IFN)-gamma, eotaxin, and regulated on activation, normal T cell expressed and secreted (RANTES) in nasal lavage fluid in both groups. RESULTS: Eotaxin, GM-CSF, IL-8, IFN-gamma and TNF-alpha were higher in the RSV group than the control group. TNF-alpha correlated with an eosinophil-active cytokine, GM-CSF (r=0.86, P<0.0001), IFN-gamma (r=0.90, P<0.0001), and with eosinophil-active C-C chemokines such as eotaxin (r=0.50, P<0.0001). TNF-alpha also correlated with proinflammatory cytokines such as IL-8 (r= 0.81, P<0.0001). CONCLUSION: TNF-alpha correlated with eosinophil-active chemokines and cytokines. Therefore, TNF-alpha may have a role in eosinophilic inflammation in children with RSV bronchiolitis.

An analytical observation was carried out on clinical features manifested by 435 patients admitted to Sacred Heart Hospital under a diagnosis of hypertension for a period of June 1968 to August 1972. The following results were obtained: 1. The occurence rate of hypertension was like to be higher in males than in females, showing a ratio of 3:2. The group of the 6th decade of age showed the densest distribution followed the groups in the 5th and the 7th decades, in either sex. 2. The average measurement of blood pressure in patients with hypertension for less than 2 years of duration was 174.8+/-25.14/114.0+/-18.72 mmHg. One who had suffered for over 10 years showed 189.7+/-32.02/126.6+/-23.95mmHg. The value had a tendency to increase as the ailment duration prolonged. 3. In eye fundus findings,hypertensive retinopathy of K-W stage II was the most frequent, observed in 39.0% of all. The appearing rate of hypertensive retinopathy increased and the change in the eye ground was accentuated as the ailment lingered longer. There was no noticeable correlative evidence between serum cholesterol and retinopathy by K-W classification, while the appearing rate of arteriosclerosis in the eye ground by Scheie's classification somewhat increased as serum cholesterol elevated. 4. Albuminuria was observed in 62.9% of all cases, a tendency of a higher appearing rate in parallel with the protraction of illness and a higher measurement of blood pressure. 5. The appearing rate of albuminuria increased as the change of eye fundus deepened. 6. The mean value of serum cholesterol was 192.0mg%, and there was no difference in cholesterol determination by age. 7. The ECG revealed an abnormal tracing in 78.0% of all cases, of which LVH was the most common abnormality appearing in 62.3%. The abnormalities in ECG were found more frequently as the illness protracted longer and blood pressure measured higher. 8. The chest X-ray showed abnormal findings in 55.6% of all cases, of which cardiomegaly was the most common change evidenced in 43.9%. 9. The cerebrovascular accident(22.9%), cardiac failure(8.6%) and renal insufficiency(7.9%) were the major complications of hypertension. The cerebrovascular accident was also found in higher occurence in the cases of longer duration of ailment with hypertension.

This study was undertaken to investigate the change of ear swelling response (ESR) of the mice according to repetitive ultraviolet radiation. 100mJ/crn of UVB was irradiated daily for 4 weeks, and a total of 25 C57BL mice were used as subjects. The results were as follows : 1. After 1 day, 2 days and 3 days irradiation of UVB, ESR reached 21.3+/-1.5, 22.3+/-1.1 and 24.3+/-1.6 respectively with increasing tendency, but there was no statistical significance (Wilcoxon rank sum test p>0.05). 2. ESR reached at maximum, 78.0+/-1.8, after 1 week(p<0.01), thereafter ESR decreased gradually with reparative process. 3. Inspite of continued irradiation, ESR decreased gradually after 2 weeks. After 2 weeks, 3 weeks and 4 weeks irradiation, ESR decreased to 51.6+/-11.8, 45.1+/- 3.3 and 42.8+/-6.8 respectively, but, there were still increment of ESR (p<0.01).

BACKGROUND: Several studies have been conducted on the role of the p63 gene family in non-small cell lung carcinoma (NSCLC). Nevertheless, the role of these genes in the development and progression of NSCLC remains controversial. This study was designed to examine the expression and clinicopathologic significance of the p63 family in NSCLC. METHODS: Immunohistochemical staining was performed on 92 cases of NSCLC (47 squamous cell carcinomas [SqCCs] and 45 adenocarcinomas [ACs]) using tissue microarray blocks. The results were analyzed and correlated with clinicopathologic data. RESULTS: The expression of delta Np63 (Delta Np63) was elevated in SqCC (39/47), but not in AC (2/45; p<0.01). Both p63 and Delta Np63 had high expression in 39 SqCCs; p63 and Delta Np63 also had a similar geomorphologic distribution in most positive tumors. The expression of Delta Np63 was correlated with histologic type, gender, pT stage, p53 expression, and p63 expression. pT and pN stages were independent factors in survival (p<0.05, respectively). CONCLUSIONS: The major p63 isoform in NSCLC, Delta Np63, had a strong correlation with p53 and p63, and was exclusively expressed in SqCC. However, our findings suggest that Delta Np63 was not an independent prognostic factor for NSCLC.

BACKGROUND: Xanthium stramarium (XAS) and Psoralea corylifolia (PSC), phototoxic oriental medicinal plants, has been used in traditional medicines in Asian countries. OBJECTIVE: The effects of highly purified XAS or PSC extract combined with ultraviolet A1 (UVA1) irradiation on cell proliferation and transforming growth factor-beta1 (TGF-beta1) expression of the keloid fibroblast were being investigated to define potential therapeutic uses for keloid treatments. METHODS: The keloid fibroblasts were treated with XAS or PSC alone or in the combination with UVA1 irradiation. The cell viability, apoptosis, and expression of TGF-beta1 and collagen I were investigated. RESULTS: XAS and PSC in combination with UVA1 irradiation suppressed cell proliferation and induced apoptosis of keloid fibroblasts. Furthermore, the XAS and PSC in combination with UVA1 irradiation inhibited TGF-beta1 expression and collagen synthesis in keloid fibroblasts. CONCLUSION: These findings may open up the possibility of clinically used XAS or PSC in combination with UVA1 irradiation for keloid treatments.

Retraction of any part of the brain may damage the cortex as well as the parenchyma, so it is advisable to retract the brain with the least force necessary and for the shortest time as possible. The purpose of this study was to examine in cats the damage caused by retraction of the brain by measuring the regional blood flow and brain edema, and to determine which of two methods, continuous or intermittent brain retraction, is less harmful to the brain. Twenty five adult cats weighting 2.5 to 4.0Kg, were used in this study. The twenty five cats were divided into three groups ; control (n=5), continuous retraction (n=10) and intermittent retraction groups (n=10) respectively. The brain retraction was produced by applying the lead weight with the stainless retractor on the right frontal lobe through a craniectomy at the right frontal bone. The weight (20g) was supported throught the pulley so that its long axis was perpendicular to the cortical surface. In the continuous retraction group, the brain was retracted for 180 min with a retraction force of 20g and in the intermittent retraction group, a 15 min period of retraction was applied, followed by a 5 min release, repeated nine times. The regional cerebral blood flow (rCBF) and brain specific gravity measurements were carried out in each animal before and immediately after brain retraction, at the 30th min, 60th min, 90th min, 120th min, 150th min and 180th min after retraction. The rCBF was measured by hydrogen clearance method and the brain edema was measured by gravimetric technique. The results were as follows : 1) After the brain retraction, there were rise in blood pressure and bradycardia in 60 min. 2) Normal control cerebral blood flow (rCBF, ml/100g/min) were 38.7+/-1.9 in right frontal, 38.7+/-1.7 in left frontal, 38.6+/-2.3 in right parietal and 38.2+/-2,3 in left parietal lobes. 3) A considerable reduction in rCBF at the retraction site, has been demonstrated with continuous brain retraction in 60 min after retraction. A reduction in rCBF to 30% of control (RF ; 28.2+/-2.1ml/100g/min) in 180 min after continuous retraction of the right frontal lobe, however, intermittent retraction resulted in a reduction of flow to 12% of control(RF ; 37.5+/-2.9ml/100g/min) at retraction site in 180 min after retraction. 4) The changes of brain specific gravity relatively began to notice at rCBF less than 23.0ml/100g/min. It might be inferred from these that intermittent retraction was less harmful to the brain, which indicate adequate arterial blood flow under the retractor was vital for the preservation and return of the neuronal function following brain retraction.

STUDY DESIGN: An in-vitro experiment using human ligamentum flavum (LF) and the adnovirus-BMP-2 construct, Ad/BMP-2. OBJECTIVES: To determine the dual roles of LF as an osteoinductive agent and carrier for ex-vivo gene transfer. SUMMARY OF LITERATURE REVIEW: LF is known to have osteogenic potential. Pathologically, ossified LF may cause myelopathy and radiculopathy. BMP-2 is known as an important factor in the differentiation, and maintenance, of osteoblast phenotypes. Ex-vivo gene transfer, using human LF for spinal fusion, has never been attempted before. MATERIALS AND METHODS: The LF cells were cultured from the degenerated LF of spinal stenosis patients. An adenovirus construct, containing BMP-2 cDNA (Ad/BMP-2), was also produced. The LF cell cultures were exposed to the adenoviral construct. The Osteocalcin expression was analysed by Western blot analysis. The osteocalcin and BMP-2 mRNA expressions were analysed by RT-PCR. Bone formation was assessed by alkaline phosphatase and Von Kossa stains. RESULTS: The LF cell cultures, with Ad/BMP-2, showed transgene expression in the Western blot analysis. Also, the cultures exhibited the mRNA expressions of both osteocalcin and BMP-2, in a dose-dependent manner. The LF cultures, with Ad/BMP-2, demonstrated alkaline phosphatase expression and bone nodule formations from the Von Kossa staining. CONCLUSION: The genetically modified LF strongly induced osteogenesis, which can be used during a spinal fusion, as an osteoinductive agent and carrier, for ex-vivo gene transfer.
