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.

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.

Eczema herpeticum is a herpes simplex virus infection with disseminated skin involvement superimposed on a pre-existing dermatosis. Dariers disease has been reported to be among the dermatoses susceptible to the sudden onset of a widespread vesicular eruption accompanied by high fever known as Kaposis varicelliform eruption. We report a case of eczema herpeticum in a 46-year-old woman associated with Dariers disease.

A case of eosinophilic granuloma in 38-year-old male was reported. The patient was admitted with chief complaints of pain on the left thigh, tenderness and limping associated with localized swelling on upper 1/3 of left thigh. The diagnosis was confirmed by radiological evidence and biopsy findings. This case was healed completely by curettage. The review of literature was made briefly.

PURPOSE: The aim of this retrospective study was to evaluate the risk of local recurrence such as patients who were treated for Dukes stage B and C low rectal cancer by abdominoperineal resection (APR) or low anterior resection (LAR). METHODS: From 1985 to 1995, 81 patients with low rectal cancers which were within 3~8 cm from the anal verge were treated by curative resection, 38 by APR and 43 by LAR. The present study examined clinical and tumor characteristics, type of intervention as potential predictors of local recurrence. Retrospective data were analysed by univariate Chi-square tests. RESULTS: Local recurrence was diagnosed in 17 of 81 patients with a median follow-up period of 24 months. The local recurrence rate was 23.6% (9 of 38) after APR and 18.6% (8 of 43) after LAR. There was no difference in local recurrence between patients who had APR and LAR (P=0.58). Also we could not find any significant differences among age (< or =65 vs >65 years, P=0.53), sex (M vs F, P=0.57), sized of tumors (< or =5 vs >5 cm, P=0.32), distance from anal verge (< or =5 vs >5 cm, P=0.57), Dukes stage (B vs C, P=0.22), histological grade (well and moderate vs poorly, P=0.17), distance from distal resection margin (< or =2 vs >2 cm, P=0.35). CONCLUSIONS: The tumor factors such as Dukes' stage were more critical for pelvic recurrences than other patient factors.

BACKGROUND: Surfactant protein A (SP-A) is important in the regulation of surfactant secretion, synthesis and recycling. SP-A has important roles in regulating surfactant metabolism as well as in determining surfactant's physical properties. Since systemic sepsis is one of the common causes of acute respiratory distress syndrome (ARDS) and abnormalities in surfactant function have been described in ARDS, the authors investigated the effects of endotoxemia on the accumulation of mRNA encoding SP-A and SP-A protein content. METHODS: Adult rats were given various doses of intraperitoneal endotoxin from Salmonella enteritidis and sacrificed at different times. SP-A mRNA was measured by filter hybridization method. Lung SP-A protein content was determined by double sandwich ELISA assay using a polyclonal antiserum raised in rabbits against purified rat SP-A. RESULTS: 1) The accumulation of SP-A mFNA in the endotoxin treated group 24 hours after 2mg/kg and 5mg/kg endotosin treatments was significantly increased 50.9% and 27.3%, respectively, compared to the control group (P<0.001, P<0.025). 2) The accumulation of SP-A mRNA 24 hours in the 5mg/kg endotoxin treated group was significantly increased by 26.5% compared to the control group (P<0.01). 3) Total amount of lung SP-A was not altered at 24 hours by various doses of treatment. Total lung Sp-A content 144 hours after endotoxin administration was significantly decreased by 51.4% compared to the control group (P<0.01) CONCLUSIONS: The specific regulation of SP-A by various time course in vivo is evident. The late decline in SP-A protein content was unexpected and suggests that SP-A may be differentially regulated during lung inflammation. The functional significance of these alterations remains to be clarified.

The most common cause of isolated oculomotor nerve palsy is ischemia of the peripheral nerve caused by a disease, such as diabetes mellitus. Another common cause of isolated oculomotor nerve palsy is compression by an intracranial aneurysm, usually an posterior communicating artery aneurysm. However, it is extremely rare in the pituitary tumor. We report an unusual case of pituitary adenoma presenting with isolated oculomotor nerve palsy in the setting of pituitary apoplexy. We suggest that pituitary apoplexy should be included in the differential diagnosis of a patient with isolated oculomotor nerve palsy and early surgery should be considered for preservation of oculomotor nerve function.
