Two techniques are available for endovascular treatment of post-SAH vasospasm: mechanical angioplasty and phamacologic infusion(papaverine or other vasodilator). The advantages of papaverine infusion are simplicity, safety, and the ability to reach small distal vessels. The disadvantages are that the treatment results may be temporary and inconsistant. The advantages of balloon angioplasty are rapid, dramatic result and consistantly successful. It is important to treat vasospasm as soon as possible for two reasons: vascular response is better and permanant ischemic damage is minimized. If ischemic symptom have developed, it may already to be late. So, the treatment of vasospasm should be proreactive rather than reactive.

A variety of technique of dynamic pharmacocavernosometry have been described to evaluate cavernous veno-occlusive function: however, there is no uniquely reliable and standard method so far After intracavernous (IC) injection of 45 mg papaverine and 2.5 mg phenblamine, we performed gravity cavernosometry(GC) and pump cavernosometry(PC), ie, measurement of saline infusion rate needed to obtain and to maintain an erection and measurement of pressure decay for 30 seconds and pressure drop time to 75 mmHg when pump was turned off at 150 mmHg IC pressure. Final diagnosis of venous leakage was made by cavernosoeraphy done at 90 mmHg IC pressure. The parametric values measured by each method to diagnose venous leakage and correlation among these methods were analyzed. The etiology of impotence in 45 patients studied was psychogenic in 8, venogenic in 21, combined arteriogenic and venogenic in 16. The measurement of induction flow rate was less reliable(p<0.05) for the diagnosis of venous leak than the other methods of PC and GC (p<0.01). The standard deviations of the induction and maintenance flow rate and pressure drop time were similar to or even higher than mean values. There was correlation among all these methods. Therefore, GC and PC, particularly measurement of the intracorporeal pressure decay are believed to be valuable methods for diagnosis of the corporal-venous leakage.

Snap Gauge bands were applied to measure nocturnal penile rigidity in the impotent patients and the results were compared with PBI and findings of the papaverine induced artificial erection. The results were as follows: 1. The results of Snap Gauge test were relatively competitive with the degree of erectile dysfunction which organic impotent patients complained of. 2. PBI less than 0.85 implied insufficient rigidity and PBI over 0.95 showed sufficient rigidity in Snap Gauge tests. 3. The possibility of "false positive" or "false normal" in diagnosis of the impotence was higher in the papaverine induced artificial erection tests than in the Snap Gauge tests. Conclusively, Snap Gauge band is simple to use and effective to measure quantitatively the penile rigidity reached during nocturnal erections in impotent patients.

The purpose of this paper is to investigate the possible correlation between the choroidal blood flow and the amplitude of the b-wave in albino rabbits. The following vasoactive drugs were administered intravenously in order to change the blood flow, and the blood flow and the ERG were measured in the dark room after 30 minutes' dark adaptation. Epinephrine (0.5 mg/kg) produced slight reduction in the b-potential only when the blood flow decreased more than 10%. Pitressin (0.1 micro/kg) induced marked degree of blood flow reduction and this changes were always associated with parallel reduction in the b-potentiaI. Papaverine (2 mg/kg) also produced marked increase in blood flow and marked increase in the bpotential parallel to it. Hexamethonium bromide (1 mg/kg) produced parallel changes in the blood flow and the b-potential only when the blood flow decreased. Reserpine (0.2 mg/kg) induced moderate increase in the blood flow and this increase was associated with the increase in the b-potential. The possible applications of these results in the clinical practice were discussed.

PURPOSE: This study was aimed to compare the erectile response when phentolamine of intracavernous trimix(papaverine, phentolamine, alprostadil) was replaced with chlorpromazine. MATERIALS AND METHODS: A total of 65 patients with erectile dysfunction(63.3+/-9.19 years of age) who had already used intracavernous injection with trimix(4.5+/-2.12 years) were recruited for this study. The erection quality and adverse reactions of chlorpromazine solution were compared with those of trimix. RESULTS: Among 65 patients, the erection quality of the intracavernous chlorpromazine solution compared to that of trimix was worse in 26 patients(40%), better in 8(12.3%) and similar in 31(47.7%) when injected at the clinic. Among 45 patients who used the chlorpromazine solution for intracavernous self-injection at home for more than 3 months, however, the erection quality was worse in 13(28.9%), better in 8(17.8%) and similar in 24(53.3%). Intracavernous chlorpromazine solution-either injected at the clinic or self-injected-showed no significant adverse reaction. CONCLUSIONS: Chlorpromazine could be a safe and effective substitude of phentolamine of trimix.
