Opacification of the gallbladder after parenteral administration of contrast material usually indicates diminished renal function but can occur with normal renal function. The authors recently experienced 13 cases of such vicarious excretion of contrast media. Among 13 patients. 9 patients had renal disease unilateral ureteral stone(n=3), staghorn calculi(n=2), acute renal failure from sepsis(n=1), renal contusion(n=2) and unilateral renal artery involvement by dissecting aortic aneurysm(n=1). Of these 9 patients, 3 patients showed abnormal serum creatinine levels at the time of presentation or shortly thereafter. In 6 patients, injection of a large amount of contrast media was possibly the additional cause of vicarius excretion. There was no detectable cause in the remaining 4 patients. Heterotopic excretion of contrast media is clearly a complex phenomenon, the reason for which it is difficult to establish with certainty in each individual case. Anyhow, vicarius excretion of contrast media occurs more frequently than previously thought, and it can occur not only with abnormal renal function but with normal function also.

The aim of this study was to compare with the effects of baclofen using an animal model of neuropathic pain. The sciatic nerve of rats was ligated unilaterally about dorsal half-portion in the tight according to the method of Seltzer and his colleague. After surgical operation, the rats showed painful symptoms of the ipsilateral hind paw, suggesting the possibility of spontaneous pain. And then, the paw withdrawal latency to the local heating on the paw through the glass plate and the frequency of paw withdrawal response to innocuous mechanical stimulation with modified von Frey filaments were determined to compare with the effects of pre-and post-medication of baclofen, respectively, at postoperative 3, 7, and 10 days. The results obtained were as follows: 1) The thermal hyperalgesia and mechanical allodynia produced by partially tight ligation of sciatic nerve appeared continously postoperative 3 days later. 2) In the hyperesthetic rats, the thermal hyperalgesia was inhibited from the 3rd posroperative day with orally administered baclofen 0.2mg and 1.0mg. 3) In the hyperesthetic rats, the mechanical allodynia was inhibited with baclofen 0.2mg, but not with baclofen 1.0mg, These results suggest that baclofen have more specific effects on thermal hyperalgesia than mechanical allodynia.

BACKGROUND: We studied the antibiotic sensitivities to the causative microorganisms of acute simple urinary tract infection for recent 3 years. METHODS: We analyzed 112 microorganisms and their antibiotic sensitivities of the 104 patients who were admitted to or visited the Department of Urology, Catholic University St. Marys Hospital and had more than 10cfu/mL on urine culture from June 1996 to January 1999 retrospectively. RESULTS: The chance of gram negative and positive as causative microorganisms was 72.3% and 27.7% respectively. The most common pathogenic microorganisms were Escherichia coli (67.0%) followed by a-hemolytic streptococci, Entercoccus. In gram negative acute UTI, imipenem, sulperanzone showed relatively higher sensitivity, while cotrimoxazole, ampicillin showed relatively lower sensitivity. In gram positive, vancomycin, penicillin showed relatively higher sensitivity, while ampicillin, imipenem showed relatively lower sensitivity. CONCLUSIONS: We consider that gram negative microorganisms, especially E. coli, is the main cause of acute simple UTI. But, we should be concerned about the increase of gram positive organisms and other gram negative organisms besides E. coli. Regarding to the choice of adequate drug in the treatment of UTI, it is necessary to consider the change of pathologic microorganisms.

A clinical observation was made on 236 cases of bladder tumor admitted to the Department of Urology, Presbyterian Medical Center during the period from August, 1970 through July, 1980 and the following results were obtained. 1. Among 236 cases of in-patients, 188 cases were male and 48 female with 4:1 ratio. 2. Main age distribution was between 40 and 70 years, showing the highest incidence in 60 to 69 years (33. 1%). 3. The clinical manifestation included hematuria (81.4%), dysuria (27. 6%), frequency(24. 6%) and other symptoms. 4. The tumors were located in the base and lateral wall of bladder (67%) mainly. 5. On I. V. P. findings, 135 cases(57. 2%) were normal, 40 cases (17. 0%) showed unilateral hydronephrosis and 14 cases (6.0%) bilateral hydronephrosis. 5. Of 235 cases of bladder tumor, 181 (76.6%) were transitional cell carcinoma, 10 cases (4.3%) of squamous cell carcinoma and 4 cases of adenocarcinoma (1. 7%). 7. On treatment of bladder tumor, T. U. R. was performed on 122 cases, total cystectomy 57. radiation therapy 33 and thio-TEPA bladder instillation 28.

This study was undertaken to document the effect of transforming growth factor-beta2 (TGF-beta2(TGF-beta2) and basic fibroblast growth factor (bFGF) on the proliferation of pig retinal pigment epithelial cells (RPE). Whereas bFGF increased the proliferation, TGF-beta2 showed the inhibitory effect on the proliferation The inhibitory effect of TGF-beta2 disappeared in RPE subcultured with 10ng/ml of bFGF. Both TGF-beta2- and bFGF-specific antisense oligonucleotides blocked the autocrine effect of the growth factors. PLC-71 -specific antisense oligonucleotide inhibited the effect of TGF-beta2 and bFGF. Genistein inhibited the effect of TGF-beta2 and bFGF in dose-dependent man, ner. The data suggest the involvement. of in PLC-/1 and tyrosine kinase in signalling.

Lidocaline if frequently administered as a component of an anesthetic : for local or regional nerve blocks, to mitigate the autonomic response to laryngoscopy and tracheal intubation, to suppress the cough reflex, and for antiarrythmic therapy. Diazepam dectease the potential central nervous system (CNS) toxicity of local anesthetic agents but -may modify the sitmulant action of lidocaine in addition to their own cardiovascular depressant. The potential cardiovascular toxicity of local anesthetics may be enhanced by the concomitant administration of diazepam. This study was designed to investigate the effects of lidocaine dose and pretreated diazepam to cardiovascular system and plasma concentration of lidocaine. Lidocaine in 100 mcg/kg/min, 200 mcg/kg/min, and 300 mcg/kg/min was given by sequential infusion to dogs anesthetized with halothane-nitrous oxide (Group I). And in group II, after diazepam pretreatment, lidocaine was infused by same way when lidocaine was administered in 100 mcg/kg/min, the low plasma levels (3.97+/-0.22-4.48+/-0.36 mcg/ml) caused a little reduction in cardiovascular hemodynamics. As administered in 200 mcg/kg/min, 300 mcg/kg/min, the higher plasma levels (7.50+/-0.66-11.83+/-0.59 mcg/ml) reduced mean arterial pressure (MAP), cardiac index (CI), stroke index (SI), left ventricular stroke work index (LVSWI), and right ventricular stroke work index (PVSWI) and incresed pulmonary artery wedge pressure (PAWP), central venous pressure (CVP), systemic vascular resistance index (SVRI), but was assciated with little changes of heart rate (HR), mean pulmonary artery pressure (MPAP), and pulmonary vascular resistance index (PVM). When lidocaine with pretreated diazepam was administered in 100 mcg/kg/min, the low plasma level, the lower level than when only lidocaine administered. reduced MAP, but was not changed other cardiovascular hemodynamics. While lidocaine was infused in 200 mcg/kg/min, 300 mcg/kg/min in dogs pretreated diazepam, the higher plasma level (7.64+/-0.79-13.79+/-0.82 mcg/ml) was maintained and was associated with reduced CI, SI, LVSWI and incresed PAWP, CVP, SVRI but was a little changes of HR, MPAP, PVRI. After CaCl2 administeration, CI, SI, SVRI, LVSWI was recovered but PAWP, UP was rather incresed than recovered. The foregoing results demonstrate that pretreated diazepam imposes no additional burden on cardiovascular system when a infusion of large dose of lidocaine is given to dogs anesthetized with halothanenitrous oxide. But caution may be advised if the addition of lidocaine is indicated in subjects who have impared autonomic nervous system and who are in hypercarbic, hypoxic, or acidotic states.
