Two cases of ureteral fibrous polyp showing serpiginous filling defect on IVP are presented with characteristic radiologic features; easy flow of contrast medium around polyp. Prolapsed polyp in urinary bladder, and less ureteral obstruction or renal damage than in epithelial lesions. These rediologic findings enable to differentiation of ureteral fibrous polyps from malignant tumor, which is helpful for determining therapeutic approach.

The purpose of this paper is to review the colonofiberscopic findings in the 21 patients with tuberculous colitis, diagnosed by colonofiberscopic findings including histopathology and by follow-up observation after anti-tuberculosis chemotherapy. The results are as follows: 1) The male to female ratio was l. 33(R:4) and the average age of the patiets were 34. 9 years in men and women respectively. 2) The chief complaints were abdominal pain in 15 cases(71.4%), diarrhea in 14(66.7%), weight loss in 12(57. 1%), anorexia in 8(38, 1%), and so on. 3) Anemia and an increase in ESR were major abnormalities in hemogram. 4) On the chest X-ray examination, 65% of the cases showed active tuberculous lesions and the barium enema disclosed the changes suggesting tuberculous colitis in 52. 6% of the cases. 5) On colonofiberscopy 8 cases were ulcerative, 6 were hypertropbic and 7 were ulcerohypertrophic. 6) Histopathologic examination of the biopsy material from the colonofiberscopy revealed granulomata with caseation necrosis in 2 cases, granulomata without caseation necrosis in 8 cases, and the findings of chronic inflammation in 11 cases. 7) This study suggests importance of colonoscopic examination including histopathologic study of the biopsy material in the diagnosis of tuberculous colitis. The diagnostic efficieocy would be much improved if bacteriological examinations of the specimen could be developed.

We experienced 43 cases of traumatic hyphema for one year. The cases of angle recession following traumatic hyphema were 36 of 43 patients(84%). The average degree of angle recession of these patients was 286 degrees. The cases of persistent elevation of intraocular pressure among these 36 anglerecessed patients were 13(36%). Their average degree of angle recession was 309 degrees. Our result suggest necessity of the careful measurement of intraocular pressure and long-term follow-up in traumatic hyphema patient.

The authors evaluated the stress response to cardiopulmonary bypass by measuring plasma Ig G, A, M and C3, C4concentrations. Anesthesia was induced with fentanyl, and all patients were underwent open heart surgery using bubble type heart-lung machine. Blood samples were obtained pre-induction, sternotomy, 10 min. and 30 min. after cardiopulmonary bypass, and 10 min. after termina tion of cardiopulmonary bypass and after transport to L.C.U. IgG, A, M and complement C3, C4concentrations were measured by Turbidmeter using Behring Turbidquant. The results were as follows: 1) Plasma concentrations of IgG, A, M and C3, C4 at preinduction period were 1345. 00+/-194. 42, 289. 10+/-100.4, 177.43+/-72.65, 59.20+/-16.33, 20.50+/-7.54 mg/dl., respectively. 2) Ten min. after cardiopulmonary bypass, the plasma concentration was significantly decreased when compared with the baseline values (p<0.01). 3) Thirty min. after cardiopulmonary bypass, the plasma concentration of the complenent C3, C4 were significantly decreascd (p<0.01). 4) In the 1ntensive care unit, Ig and complement C3, C4 were increased, but did not reach control values. Considering the above results, we conclude that the decrease of plasma Ig G, A, M and complenent C3, C4concentrations are related to mechanical stress of the cardiopulmonary bypass, and to certain activators such as denaturated protein, heterogenous RBCs, and foreign materials, etc.

Although crystalloid solutions such as Ringer's lactate have become the standard for initial volume replacement after hemorrhage, it is controversy whether this fluid alone restores and maintains the depressed physiologic function after severe hemorrhage. Six anesthetized dogs were bled(35ml/kg) and resuscitated with Ringers lactate solution (100 ml/kg). Physiologic variables are measured initialy, after hemorrhage, after resucitation. Compared with initial value, after resuscitation data show marked reduction in hemoglobin, oxygen carrying capacity, vascular resistance, and electrolyte. But cardiac output and blood gas analysis data was not changed. Prothrombin time and partial thromboplastin time was prolongated. From this study crystalloid resuscitation in severe hemorrhagic shock restore cardiac output and perfusion, but fail to maintain adequate oxygen carrying capacity.

The role of the donor and recipient gender have been a controversial point in the outcome of renal transplantation and the pathophysiologic mechanisms are not understood clearly. In order to evaluate the effect of gender on the renal graft survival, we reviewed our 400 consecutive living donor renal transplantation. The patients were divided into four groups, Group 1; male donor and male recipient(n=152), Group 2; female donor and male recipient(n=61), Group 3; male donor and female recipient(n=135), and Group 4; female donor and female recipient(n=52). To estimate the transplant outcome between the groups, we analyzed patient and graft survival, acute tubular necrosis, BUN, creatinine and rejection episode for maximum 5 years after transplantation. The level of BUN(34.7+/- 26.4, 19.8+/- 6.4, 30.5+/- 14.6, 23.1+/- 10.5 in group 1,2,3,4 respectively) and serum creatinine(2.62+/- 2.3, 1.48+/- 1.1, 2.24+/- 1.2, 1.65+/- 0.9 in group 1,2,3,4 respectively) were higher in male recipient groups regardless of donor gender. However, donor and recipient gender had no influence on post-graft blood pressure and acute tubular necrosis(p>0.05). Acute rejection episode was predominent at female donor graft than male donor graft(36.4% vs 30.1%). The 5 year graft survival in group 1,2,3,4 were 67.8, 67.2, 60.1, 72.7% and patient survival were 76.9, 75.6, 72.6, 80.5% in their orders. These results suggest that donor and recipient gender might play a role in the outcome of renal transplantation. The mechanism of these results must be analyzed by further evaluation using larger patient group.
