Skull base surgery has developed through the evolution of imaging, anatomic research, surgical approach and reconstructive techiques. The basic disciplines of approaching skull base lesions are to provide direct vision, minimize brain retraction, allow excellent exposure and minimal blood loss. Although many advantages listed above are reported, objective long-term follow up results about post-operative complications of this procedures were not introduced. This study was designed to review the complications of skull base approach that we experienced 43 cases by a team approach with neurosurgery-supraorbital rim osteotomy, orbitozygomatic osteotomy, orbitozygom aticoglen-oidotomy, orbitozygomaticoglenoidocondylotomy, and transfrontonasomaxillary osteotomy-through objective evalutation criteria. The result of this study demonstrated that the type of complications were consisted with perioperative infection (5 cases), subdural empyema (1 case), CSF leakage(1 case), hematoma (1 case), meningitis (3 cases), ophthalmic nerve injury (1 case),facial nerve injury (2 cases), T-M joint problem ( 2 cases), & enophthalmos ( 2cases). In conclusion, after performing the different skull base approaches, we analyzed several complications of the above procedures. We analyzed with the purpose of preventing complications in the next skull base approach.

BACKGROUND: Intracellular calcium overload is a common final feature of the ischemic-reperfused heart and mediates the genesis of irreversible cell damage. Reactive oxygen medabolites have been known to play and important role as toxic mediators in myocardial injuries resulting from ischemia and reperfusion. In order to investigate the mechanism of intracellular calcium accumulation in the ischemic-reperfused myocardium, the present study observed the possible contribution of the reactive oxygen metabolite to the calcium transport of cardiac mitochondria. METHODS: Mitochondrial were isolated from rabbit hearts. The effects of a reactive oxygen metabolite, H2O2 on calcium uptake and release, redox states of endogenous pyridine nucleotides and glutathiones of mitochondria respiring with succinate were observed. Calcium uptake and release were monitored by dual-wave length spectrophotometer using a calcium indicator, arsenaze III. Contents and redox states of pyridine nucleotides and glutathiones were measured by enzymatic methods using spectrofluorometer and HPLC. RESULTS: Hydrogen peroxide(10-500microM) promoted calcium release dose-dependently from CA++-preloaded mitochondria, but did not affect the mitochondrial calcium uptake. The H2O2-induced calcium release was accompanied by simultaneous oxidation of the pyridine nucleotides and decrease in the content of the reduced form of glutathione(GSH). When mitochondria were treated with BCNU(N,N=bis(2-chloroethyl)-N-nitrosourea) to inhibit glutathione reductase and so as to reduce the GSH content, there were no increase in calcium release from the mitochondria. These results may indicate that H2O2 increases the permeability of cardiac mitochondrial membrane to calcium in association with the changes in redox state of endogenous pyridine nucleotides, but not with that of glutathiones. CONCLUSION: It is suggested that the reactive oxygen metabolites induce the release of calcium from mitochondria by altering the redox state of pyridine nucleotides, and it may partly be involved in the elevation of cytosolic calcium concentration in the ischemic-reperfused myocardial cells.

Pneumocystis carinii pneumonia is caused by Pneumocystis carinii. It usually occurs in premature or debilitated infants. Recently sporadic cases of human disease in patients who have been on long term steroid therapy, cytotoxic drug therapy, immunosuppressive drug were significantly increased. We recently experienced 35 cases of Pneumocystis carinii pneumonia in infants of an institution for foreign adoption in three epidemic period of Feb.1979, Mar. 1980, and Jan. 1980. The clinical review of 35 cases was made. Patients' age was between 1 to 4 months. Twenty-one cases (60%) occurred in 2-month-old infants. Many patients were included in poor weight gain and development. The common symptoms were tachypnea, cyanosis, restlessness, cough, diarrhea in order of frequency. The roentgenological findings were classified into three groups. normal finding, pulmonary emphysema only, and various forms of pneumonic infiltration. The roentgenological findings were somewhat characteristic. The most common finding (24 cases) showed streaky and mottled densities which began in both hill and were spreaded peripherally. The pneumonic infiltrations were spared peripheral lung, but progressed to total involvement. The prominence between alveolar and interstitial infiltration was almostly equal when patients were admitted. Nineteen cases (54%) showed pulmonary emphysema.

Lawsonia intracellularis is not culturable with a standard bacteriologic culture. One step PCR assay as a clinical diagnostic method was developed for the rapid detection of porcine proliferative enteritis (PPE) caused by L. intracellularis. Primers were designed based on the p78 DNA clone of L. intracellularis. The one step PCR resulted in the formation of a specific 210-bp DNA product derived from L. intracellularis. The nonspecific amplification product was not detected with swine genomic DNA or other bacterial strains causing similar symptoms to L. intracellularis infection. The one step PCR was as sensitive as 100 pg of L. intracellularis genomic DNA. We applied this method to field specimens diagnosed as PPE by macroscopic observation. Of 17 mucosal scraping specimens, 16(94%) were identified as positive to PPE and 15(88%) of 17 feces specimens. These results suggest that the one step PCR can be used as a rapid diagnostic method for L. intracellularis infection.

Benzoyl peroxide has been known to have bacteriostatic activity against Corynebacterium acnes and to have comedolytic action in patients with acne vulgaris. The present study was undertaken to evaluate the therapeutic effect of Renoxal, a 5% benzoyl peroxide lotion, in patients with acne vulgaris. A total of 35 patients entered this study at the Department of Dermatology, Seoul National University Hospital during the five months period from March to July, 1978. All patients were instructed to apply Benoxal on their affected sites once or twice daily; and the number of lesions on three fixed areas were counted before and every week for four weeks after the treatrnent. Two female patients stopped the application due to developrnent of contact dermatitis to Benoxal The results observed in the 33 patients were as follows: 1. The percentage decrease in total number of lesions in four weeks after treatment was 51.1% 2. Closed and open comedones were gradually eliminated; and their numbers were decreased in four weeks after treatment by 45. 8% and 55. 3% respectively. The papules were decreased. by 59. 1 @2 after the first week of treatment, but showed. a transient lag around tbe second week and then marked 61. 5% in four weeks after treatment. 3. Observed side effects included burning sensation,(3 cases), tightness (3 cases), itching sensation (2 cases) and scaling (1 case). All were tolerable without any specific measure or discontinuance of the application. The authors concluded througb this experiment that Benoxal (5% benzoyl peroxide lotion) is a very effective local therapeutic agent in the treatment of acne vulgaris patients.

BACKGROUND: The importance of the determination of cell viability has prompted the development of several assays of viability that utilize the exclusion of certain dyes by viable cell membranes. Recently, flow cytometry has been adapted to estimate cell viability by using fluorescent dye which is excluded by living cells on the basis of altered dead cell properties. OBJECTIVE: We have developed a flow Cytometric method for measuring cell viability after staining with propidium iodide (PI) and have compared it with the classical colorimetric method, MTT assay, which is currently widely used in cytotoxicity assays in the research field. METHODS: We performed flow cytometry and MTT assay for the comparison of the sensitivity of the assessment of cell viability. RESULTS: Decrease of cell viability was measured by flow cytometry with the addition of as little as 0.002% Triton-X 100 in comparison to MTT assay which could only reveal a similar decrease of cell viability with the new method to 0.008% Triton-X 100. CONCLUSION: Our results demonstrate this new method to be more sensitive and simple for the assessment of cell viability.
