The isolated rabbit kidney was perfused with the blood collected from the donor rabbits. in order to investigate the substrates taken up by the rabbit kidney as the fuels of energy source. Perfusion pressure was set at 150 mmHg which was within the range of autoregulation. Blood glucose was determined by the Somogyi-Nelson method, and O2 and CO2 contents in renal artery and vein were measured by the VanSlyke mercury manometric technique. Radioactivity of 14CO2 in the blood sample derived from 14C-UL-glucose was measured by use of liquid scintillation counter. Respiratory quotient (R.Q.) of rabbit kidney was calculated from the CO2 production and O2 consumption rate. Relative specific activity (R.S.A.) of CO2 was also calculated from the specific activity of plasma glucose and specific activity of CO2. The results were as follows: 1) Average renal blood flow was 1. 41 ml/min-gm kidney. 2) COs content of renal artery and vein were 13.6 mM/L and 15. 5 mM/L respectively. (AV. difference of CO2... 1.9mM/L) and O. content of renal artery and vein were 13.6 vol% and 8.3 vol%. (Av-difference of O2.., 5. 3vol%) 3) COs production rate (VCO2) was 5l. 6 uL/min-gm kidney and O2 consumption rate(VO2) was 73. 6uL,min.gm kidney. Therefore respiratory quotient of kidney was O. r3. 4) Glucose concentration in the perfused blood was 242mg% and the specific activity of plasma glucose was 4, 439 c.p.m/,mgC of glucose. 5) The specific activity of CO2 was 40c,p.m/mgC of CO2 and the relative specific activity was 0.90%. From the above results, it was concluded that glucose is almost not used as the fuel of energy source in the rabbit kidney as found in human and dog kidneys, and suggested the possibility that fats such as free fatty acids are utilized as predominant energy source.

To determine the value of ultrasonography for the diagnosis of testicular rapture due to blunt trauma, we reviewed 69 patients of blunt scrotal trauma, which were evaluated by ultrasound before treatment. Thirty patients were managed conservatively, of which 3 cases were explored lately due to persistent pain or mass, and 39 explored immediately. Of the 30 patients treated conservatively the injury was resolved in 27. Surgical exploration of the 42 cases revealed testicular rupture in 29 and simple hematocele in 13. Analysis of the 29 cases with testicular rupture demonstrated that orchiectomy rates were 20% in early exploration and 53% in delayed exploration. in the 27 cases the testicular rupture was correctly diagnosed by ultrasonography, and there were 4 false-positive and 2 false-negative diagnoses of rupture. The specificity and sensitivity for the diagnosis of testicular rupture are 70% and 93%, and the positive and negative predictive values are 87% and 82%, respectively. Ultrasonography used in conjunction with a thorough physical examination is highly sensitive in identifying testicular rupture, and can provide objective information supporting the need for early surgical exploration in patients with blunt scrotal trauma.

A clinical observation was made on 34 patients with renal injury, who were admitted to the Department of Urology, National Police Hospital from January 1982 to December 1986. Most of patients(33 of 34) were male and 22 patients (65%) were in the age group of 3rd decade. Common causes of injury were in order of blow (29.5%), fall down(23.5%), sport mishap(23.5%) and traffic accident (20.5%). Associated injuries were noted in 30% of the cases and rib fracture was most common. Renal injuries were classified as a minor, major and pedicle injury. Of the 34 cases, 30 were minor injury, 4 were major injury, and pedicle injury was absent. Most common symptoms and signs were hematuria and flank pain. Abnormal DIP findings were noted in 11 cases (30%) and renal displacement was showed in 3 cases with perirenal hematoma and incomplete filling and extravasation were revealed in 4 cases with major injury. Of the 30 cases with minor injury conservative treatment was performed in 26, hematoma removal in 3 and nephrectomy in 1 due to UPJ obstruction. Of the 4 cases with major injury conservative treatment was performed in 2 and nephrectomy in 2.

PURPOSE: The overuse and misuse of antimicrobial agents and their resultant emergence of resistant microorganisms have made choices regarding antimicrobial therapy more difficult. We studied the changes of antibiotic sensitivity to the causative organisms of urinary tract infection(UTI) for recent 5 years in order to give some useful informations about the choice of adequate drug in the treatment of UTI. MATERIALS AND METHODS: We analysed 1191 uropathogens and their antibiotic sensitivities of the 1132 patients who admitted or visited the National Police Hospital and had more than 105cfu/ml on urine culture from January 1994 to December 1998 retrospectively. RESULTS: The common pathogenic organisms were E. coli(51.5%), staphylococcus(15.7%), pseudomonas(9.1%), klebsiella(7.5%) and enterobacter(4.0%), enterococcus(3.4%), proteus(3.1%) in order. The incidence of E. coli decreased from 50.8% in 1994 to 41.3% in 1998 but the incidence of other gram negative organisms like pseudomonas, klebsiella, enterobacter, proteus and acinetobacter increased from 24.8% in 1994 to 42.6% in 1998. In E. coli isolates(the majority of positive cultures), resistance to six antibiotics changed significantly: ampicillin(19.4% to 15.5%), piperacillin(44.1% to 32.0%), cephalothin(70.6% to 58.6%), gentamicin(62.8% to 60.2%), tobramycin(95.0% to 88.1%), and ciprofloxacin(87.6% to 76.3%). The sensitivity rates of the gram negative organisms including E. coli were very low in 1998 (ampicillin 11.6%, piperacillin 36.6%, and trimethoprim/sulfamethoxazole 49.3%). CONCLUSIONS: We think that E. coli is still the most important organism in the UTI but we shoud be concerned about the increasing incidence of other gram negative organisms like pseudomonas, klebsiella, enterobacter, proteus and acinetobacter. And prior to receiving the bacteriological report, using ampicillin, trimethoprim/sulfamethoxazole as the first choice in the treatment of UTI shoud be reconsidered.
