We designed this study to investigate the effects of adenosine on penile erection in Sprague- Dawley rats, in vivo. This was performed by simultaneous monitoring intracavernosal pressure( ICP) and systemic blood pressure with UROCOMPACT 6000 plus( WIEST, Germany) after intracavernosal injection of adenosine, papaverine and adenosine plus papaverine. Increment of maximal ICP was observed in the adenosine treated-group (0.015 to 0.15mg, n=30) in dose dependent manner, i.e., 15.8+/-0.95cmH2O with 0.015mg adenosine to 44.6+/-2.72cmH2O with 0.15mg adenosine, in mean ICP(n=l0, P<0.05). A similar finding was observed in the papaverine treated-group (0.015 to 0.15mg, n =30) in dose dependent manner. i.e., 28.1+/-2.88cmH2O with 0.015mg papaverine to 62.3+/-4.93cmH2O with 0.15mg papaverine, in mean ICP (n=10, P<0.05). The additive effect of adenosine plus papaverine treated-group( 0.015 + 0.015 to 0.15 +0.l5mg, n=30) was to enhance the results obtained by adenosine or papaverine alone in dose dependent manner. i.e., 50.7+/-1.71cmH2O with 0.015mg + 0.015mg papaverine to 79.5+/-5.63cmH2O with 0.15mg adenosine + 0.15mg papaverine. in mean ICP(n= 10, P<0.05). These results suggest that adenosine plays an important role on penile erection in rats. Adenosine may be useful for the future management of impotence, although the clinical effect remains to be investigated.

A retrospective review was performed of 297 patients admitted to Chung Ang Gil Hospital between June 1995 and December 1996 with a diagnosis of blunt chest trauma. Of these patients, 34% suffered either immediate or delayed complications. Immediate complications included hemothorax in 58.8%, pneumothorax in 26.5%, and pulmonary contusion in 20.5%. Delayed complications occurred in 9.1% of patients overall; these included pulmonary contusion in 12.7%, pneumonia in 9.8%, pulmonary embolism in 2%, poeumothorax in 2%, and hemothorax in 2%. The mean age of the patients were 43 years. 210 patients(70.7%) were under age 50 and 87(29.3%) were 50 years of age or older. Male to female ratio was 1.9:1. Mean Initial Revised Trauma Score (RTS) and the Injury Severity Score (ISS) were 7.10+/-0.94 and 14+/-8.69, respectively. There were associated injuries in 225(75.8%) patients. Overall mortality rate was 7.1% and the mortality rate was significantly greater in patients with a RTS<6, ISS>or=16, associated injuries, advanced age(50 years of age or older), and pulmonary complications. Pulmonary complications were significantly greater in patients with a RTS<6, ISS>or=16, and an associated injuries.

Priapism is a well recognized complication of some oral medications. Those most commonly cited are: antipsychotic drugs, especially the phenolhiazine: trazodone and chlorpromazine :and the antihyperlensive drugs hydralazine, guanethidine and prazocin. We report a case or priapism associated with the use of chlorpromazine who experienced 2 episodes or priapism and never experience priapism after cessation of the drug.

Suprapubic cystostomy by trocar is a simple, safe and useful method for urinary diversion in acute urinary retention. But rarely, severe complications occur during or after suprapubic cystostomy such as bowel perforation, through and through perforation of the bladder, rectal injury and severe hematuria. We studied the complications of suprapubic cystostomy retrospectively and compared 19 patients who performed ultrasonographic examination with 30 patients without ultrasonographic examination. The complications in 30 patients without preliminary ultrasonographic examination were initial failure in 4 cases (13.3%), extravesical Foley indwelling in 2 cases (6.7%), puncture site closed to the pubic bone in 2 cases (6.7%), spontaneous bladder rupture in 1 case (3.3%) and bowel injury in 1 case (3.3%). But, the complication in 19 patients with preliminary ultrasonographic examination was only 1 retried case (5.3%) because of extravesical Foley indwelling. As above results, the brief preliminary ultrasonographic examination of the bladder is a very useful method with minimal risk during suprapubic cystostomy by trocar.

The ultrasonographic features in 26 cases of blunt testicular trauma were reviewed. Ultrasonography diagnosed correctly in 11 surgically proven cases of testicular rupture. There were three false-positive cases, two with a large scrotal hematocele and one with epididymis rupture. there were no false-negative cases. The sensitivity and specificity of ultrasonographic diagnosis were 100% and 80% respectively. The positive and negative predictive values were 78. 6% and 100% respectively. Therefore, the negative diagnosis by ultrasonography can warrant conservative therapy.

The ultrasound-guided fine needle aspirations were performed in order to diagnose a suspected neoplastic orinfectious diseases in 52 patients with focal liver disease. Of these, neoplastic lesions were suspected in 31patients and infectious lesions in 21 patients ultrasonically and/or clinically. The overall accuracy for bothsuspected malignant and infectious disease was 79%(41/52). The primary indication for fine needle aspiration wasto document the presense of malignancy and to avoid a diagnostic laparotomy, and to drain hepatic abscesses.Consequently we were convinced that the ultasound

Holoprosencephaly is a rare and complex malformation affecting the cleavage of the developing forebrain and is usually associated with defects of the mid Face. We have experienced a case of holoprosencephaly, diagnosed prenatally by ultrasound examination at 31 weeks of pregnancy in a 31-year-old primigravida woman. This case is characterized by holoprosencephaly, cleft palate, cleft lip, left renal aplasia and right renal hypertrophy. The chromosomal study showed a deletion of the long arm of chromosome 7, 46, XX, del(7)(q32), We report with a terminal deletion of chromosome 7q associated with atypical clinical picture and holoprosencephaly.
