The survival of flap has a vital importance in the reconstructive surgery. This study was designed to investigate the relation of the survival area and the variation of flow value measured by laser Doppler flowmetry and to elucidate the effect of PGE1 on flap survival with an objective index. Sixteen New Zealand White rabbits were divided into 3 groups (8 of control group, 4 of intravenous PGE1 group and 4 of topical PGE1 group). The lower abdominal island flap (10 x 5 cm) based on the superficial epigastric pedicle was elevated and reset again at the previous location. The flow values were checked and it was taken as the value of LD. LD ratio was obtained by calculating the ratio of LD value in each experimental period to that of the baseline data taken before flap elevation. Finally, the data of flap survival area on the 8th experimental day was collected by using the plannimetry method. The results: the survival areas of intravenous PGE1 group (72.0 +/- 22.3%) and topical PGE1 group (78.0 +/- 22.7%) showed a significant increase compared to that of control group (46.5 +/- 14.3%, p < 0.01). The flap survival has the close relationship of the LD ratio measured immediately after flap elevation. The neovascularization period for the survival is considered at least 6 days. In conclusion, these experimental results can show an evident relation between the survival area of the flap and the LD ratio value measured immediately after the flap elevation. The LD ratio value measured immediately after flap elevation has the great significance as a critical limit for expecting the fate of flap survival. Therefore this value will be used as one of the beneficial standards for expecting the prognosis of microsurgical reconstruction in clinical trials.

PURPOSE: Intracavernosal self injection therapy is now being widely used to treat patients with erectile dysfunction. However, there is a large number of patients who give up the self injection program due to the fear of injection. Therefore, less invasive route of drug administration is highly recommended. We investigated the efficacy of intraurethral instillation of Prostaglandin El (PGE1 ) solution in the patients who showed full erection with intracavernosal injection of PGE1. MATERIALS AND METHODS: Twenty-nine impotent patients who showed full erection with intracavernosal injection of PGE1 were included in this study. We estimated the grades and durations of the penile erection after intraurethral instillation of PGE1 RESULTS: Sixteen out of 29 patients(55.2%) showed full erection with intraurethral instillation. Two patients(6.9%) showed urethral pain which disappeared within 24 hours. But there was no systemic side effect CONCLUSIONS: Intraurethral instillation of PGE1 appears to be safe, well tolerated, and less invasive treatment modality Thus it can be selected as an alternative treatment of impotence in selected cases.

PURPOSE: To evaluate whether radial rigidity measured using RigiScan(R) represents the intracorporeal pressure effectively. MATERIALS AND METHODS: From January 1998 to May 1999, total of 23 patients with erectile dysfunction were evaluated by RigiScan(R) and duplex ultrasonography after the intracorporeal injection of prostaglandin E1. Peak systolic velocity and end diastolic velocity were measured by duplex ultrasonography and then the resistance index was calculated as (peak systolic velocity-end diastolic velocity)/(peak systolic velocity). Radial rigidity of penile tip and base was measured by RigiScanR . The results were analyzed statistically by PC-SPSS version 7.5. RESULTS: There were statistically significant correlations between radial rigidity of penile tip and base and the resistance index by Spearman's correlation analysis, respectively (r=0.680, p<0.001)(r=0.703, p<0.001). When radial rigidity of penile tip and base exceeded 60% of maximum, radial rigidity of penile tip and base again correlated well with the resistance index, respectively (r=0.659, p=0.020)(r=0.759, p=0.011). Based on clinically determined degree of erection, radial rigidity of penile tip and base represented the intracorporeal pressure effectively. CONCLUSIONS: Radial rigidity measured by RigiScan(R) represents the intracorporeal pressure effectively.

Penile necrosis is a very rare complication because of its rich collateral supply. Conservative management is apt to be ineffective; thus penectomy is usually performed. We present a case of penile necrosis and claudication of both legs with multiple atherosclerosis in a type II diabetes mellitus patient who was successfully treated with angioplasty, penoplasty, and additional intracavernous injections of prostaglandin E1. The treatment resulted in relief of the leg pain and healing of the penile ischemic lesions.

Duplex ultrasonography (USG) is an accepted method to assess noninvasively arterial inflow to the penis. Optimal pharmacological agents as well as timing of the scan and stimulation during the scan continue to be debated. Between August 1994 and May 1996, 24 normal males (control group) and 45 impotent patients (impotence group) underwent penile doppler sonography, and their records were reviewed. Scans were performed at 1, 3, 5, 10, 15, 20 and 30 minutes after intracavernous injection of PGE1 (10 pg) in all subjects. Any subject not having a full erection at 15 minutes performed private self-stimulation for at least 5 minutes before the 30 minute scan. If we define normal arterial inflow as a peak systolic velocity (PSV) of 30 cm. per second or greater in the best artery, 46% of control group and 55% of impotence group achieved this velocity until 5 minutes. One (4%) of control group and three (6%) of impotence group achieved maximum velocity at 1 or 3 minutes but continually PSV of 30 cm. per second or greater after 5 minutes, so any subject may not have had an incorrect diagnosis. When we calculated maximum velocity in the best artery in relation to percentage tumescence, maximum velocity were recorded most often at 10% tumescence (46% of control group and 51% of impotence group). If we define normal arterial inflow as PSV of 30 cm. per second or greater in best artery, the cumulative percentage of patients who achieved this velocity at 1, 3, 5, 10, 15, 20 and 30 minutes were 4, 34, 46, 88, 96, 96 and 100% in control group and 6, 28, 55, 90, 92, 94 and 96% in impotence group. In conclusion, we support delaying the initial scan until 5 minutes, performing the additional scans until 30 minutes and self-stimulation when necessary. We believe all efforts should be made to have studies performed in the setting of least anxiety to the patient.

CD64 (Fc gamma RI) is the one of the three Fc gamma receptors on monocytes and represents a high affinity immunoglobin G receptor. CD64 is rapidly upregulated on monocyte in response to gamma interferone. X-linking of CD64 triggers an oxidative burst as well as antibody dependent cytotoxicity. In this experiments, peripheral blood mononuclear cells (PBMC) were separated and incubated with or without gamma interferone and PG E1. The samples were divided into four groups, the first was PBMC alone, the second was PBMC with gamma interferone 100 U/ml, the third was PBMC with gamma interferone 100 U/ml and Prostaglandin E1 1 micro M/L, and the fourth was PBMC with gamma interferone 100 U/ml and Prostaglandin E1 10 micro M /L. Flow cytometric measurements of CD64 on monocyte were performed at 0, 3, 6, and 9 hours after incubation and the mean fluorescence intensities (MFI) and the mean percentages of CD64(+) cell in monocytic gated area were obtained. After 6 hours of incubation, although there is no statistical significance, all gamma interferone added groups show the higher mean fluorescence intensity than PBMC alone group. Furthermore, at 6 and 9 hours of incubation, the mean percentages of CD64(+)cells between the PBMC with gamma interferone group and the PBMC with gamma interferone and PG E1 10 micro M/L group showed 74.83 +/- 9.72% vs. 34.07 +/-12.98%, 80.04 +/- 11.30% vs. 29.42 +/- 19.86% respectively, and there are statistical significances, p=0.05, p=0.05 respectively. It appears that PG E1 inhibits the expression of CD64 on monocyte.

After pelvic trauma, complications of urethral stricture and organic impotence may develop. Certain cases of these are combined with penile curvature, which treatment method of artificial erection alone is not suitable, because severe penile pain may occur during erection, Therefore proper surgical methods should be added for straightening the penile curvature. After pelvic trauma, complete urethral stricture and organic impotence with penile curvature developed in 3 patients who complained severe pain due to curvature during the intracavernosal injection test. To all, treatment of choice for complete urethral sticture was visual internal urethrotomy for prevention of further development of curvature, and for curvature, Nesbit's penile straightening operations were performed, one by one. All patients could well urinate and enjoy their sexual intercourse after intracavernosal injection of PGE1 or papaverine. We recommend visual internal urethrotomy and the Nesbit's operation as effective methods to treat the case of penile curvature combined with complete urethral stricture after pelvic trauma.
