We investigated the effects of panretinal photocoagulation (PRP)on macular microcirculation in diabetic retinopathy. PRP using argon blue green laser was performed in 23 eyes of 15 patients with early proliferative diabetic etinopathy and very severe nonproliferative diabetic retinopathy without significant macular edema. The changes in volume, flow, velocity of macular microcirculation were measured before PRP, 1 hour, 1 day, 1 week, and 1 month following PRP, using Heidelberg Retina Flowmeter(HRF). Mean volume, flow, velocity of macular microcirculation decreased to a maximal degree 1 hour following PRP, from 14.87+/-0.40, 387.45 +/-101.40, 1.40+/-0.28(before PRP)to 12.44+/-1.39, 347. 33+/-100.39, 1.27+/-0.34(p<0.05). From 1hour to 1 month after PRP, macular microcirculation gradually increased. However, throughout this period, all parameters of macular microcirculation remained lower than pre-PRP level(p<0.05). Our study suggests that panretinal photocoagulation reduces the macular microcirculation in diabetic retinopathy.

Respiratory syncytial virus is the most common cause of lower respiratory infection (bronchiolitis and pneumonia) of infancy and early childhood. We analyzed clinical and radiological features of 76 patients with lower respiratory infections by respiratory syncytial virus, which were diagnosed by indirect immunofluorescent test or culture of nasal aspirate in Hep-2 cell monolayer, during the period of January-December, 1991. There were peaks of incidences in March-May and November-December, accounting for 87% of eases. Sixty-two cases (82%) were under 1 year of age. Fifty cases(66%) had underlying diseases. Major radiographical findings were overaeration (83%), parahilar peribronchial infiltrates(67%), segmental or subsegmental atelectasis(32%), and segmental or lobar consolidation(16%). In 15 cases(20%), overaeration was the only radiological findings. There was no evidence of pleural effusion or hilar lymph node enlargement in all cases. By considerig clinical features(symptoms, age. Underlying diseases, epidemic seasons) in addition to the radiological findings, radiologists would be familiar with lower respiratory infection by respiratory syncytial virus. Air space consolidation, which is generally though to represent bacterial pneumonia, is also observed not infrequently in respiratory syncytial virus infections.

Chronic osteomyelitis continue to be a therapeutic challenge. The osteomyelitis also implies chronic ischemia of the diseased bone ; thus systemic antibiotic treatment may not be as effective as we want. In 1972, Klemm developed a new procedure to supplement saucerization in the treatment of chronic osteomyelitis, alternative to irrigation and suction-drainage, i.e., Gentamicin-PMMA Beads. The authors analysed 35cases of the chronic osteomyelitis which were admitted and treated by sauceriztion and Gentamicin-PMMA Beads in Department of Orthopaedic Surgery, Korea Veterans Hospital from Aug. 1984 to Jan. 1988.

PURPOSE: Matrix metalloproteinase-2 (MMP-2) and MMP-7 have been implicated in tumor growth and metastasis. This study aimed to investigate the expressions of MMP-2 and -7 in colorectal cancer and to evaluate their values as prognostic markers. METHODS: Immunohistochemical staining for MMP-2 and -7 was done in 144 resected colorectal cancer specimens. Clinicopathological data and survival results were compared with regard to the expression results. RESULTS: The expression rates of MMP-2 in tumor cells in the tumor center and the tumor border were 16.7% and 38.9%, respectively. That of MMP-2 in stromal cells was 27.8%. MMP-7 immunoreactivities of tumor cells in the tumor center and the tumor border were 6.9% and 23.6%. The expressions of MMP-2 and MMP-7 were correlated. MMP-2 expression in stromal cells was more increased in the distal part of the colorectum: 8.8% in right colon cancer, 29.5% in left colon cancer and 36.4% in rectal cancer. MMP-2 expression of tumor cells in the tumor border was correlated with T-stage. MMP-7 expression of tumor cells in the tumor border was increased in case of infiltrative cancer compared with fungating tumor. The expression patterns of MMP-2 and -7 were not correlated with other clinicopathological factors, including tumor markers, node metastasis, distant metastasis, lymphatic invasion, tumor differentiation, and recurrence. No significant associations between the overall and disease-free survival rates and the MMP-2 and -7 expression patterns were noted. CONCLUSION: The high expression rates of MMP-2 and -7 in tumor borders suggest that MMP-2 and -7 have some role in tumor invasion, but in this study, MMP-2 and -7 did not appear to be significant predictors of prognosis in colorectal cancer.

Eight patients in the state of ASA classification l, ll were investigate. Blood samples were collected before, just after, 30 minutes after and 60 minutes after induction of anesthesia. Glucose and electrolyte changes in relation to maintenance fluids in balanced and halothane anesthesia were as follows. 1) In both anesthetic techniques blood sugar level showed increasing tendency according to duration of anesthesia. 2) There were no specific changes in serum electrolytes related to type of anesthesia. 3) The administration of D/S and H/D showed a little increase in Na+ and Cl- level compared to the administration of just DsW. 4) The administration of H/d showed less increase in K+ level than the administration of DsW or D/S. 5) Just after induction of anesthesia the K+ level increased a little and decreased gradually thereafter.

Early gastric cancer(EGC) is defined as carcinoma limited to the mucosa or submucosa, regardless of whether metastasis to lymph nodes have occurred, and the frequency of lymph node metastasis varies from 7 to 18%. The incidence of early gastric cancer has been increasing recently, probably with advance in the diagnostic procedure. Multiple gastric cancer, now cosidered to be a sort of multiple primary cancer by Moertels classification, is a special type of cancer in which two or more tumor lesions arise independently from the stomach. Multiple carcinoma was found in about 8.3% of 500 early gastric cancer cases at the National Cancer Center Hospital in Japan. In 77% of these, two lesions roexisted in the stomach. Coexistence of three lesions were found in 20% and more than four lesions in 3%. We report a case of multiple early gastric cancer of different histologic types in which two adenoma coexisted in the stomach.
