N/A Background: Superior hypogastric plexus block has been advocated as a useful technique for the treatment of cancer related pelvic pain. The aim of this study was to evaluate the effect of neurolytic trans-intervertebrodiscal superior hypogastric plexus block for pelvic cancer pain. Methods: Twenty-eight patients with gynecologic, colorectal or genitourinary cancer who suffered intractable pain were studied. We performed superior hypogastric plexus block by trans-intervertebrodiscal approach at L5/Sl level under the C-arm fluoroscopic guide unilaterally or bilaterally. Ten ml of 100% dehydrated alcohol was injected through each needle. We evaluated the change of visual analog pain score (VAS; 0~100 mm) and daily dose of oral morphine sulphate at the time of pre-block and 7 days after the block. Results: Fourteen patients (50%) had satisfactory pain relief (VAS<30) while five patients (18%) had moderate pain control (VAS 30-60). The remaining nine patients (32%) had mild or little pain relief (VAS >60) and their daily oral morphine doses were above 160 mg. Additional pain control method may be needed for those patients who received high dose of opioid before neurolytic block. Conclusions: We conclude trans-intervertebrodiscal neurolytic superior hypogastric plexus block was effective in relieving pelvic cancer pain. Neurolytic block, earlier stage, may provide better effects for more comfortable life at the end stage for cancer patients.

Fe, Co, Zn, Cu, Pt 등의 전이금속과 ZSM-5 2종(SiO₂/Al₂O₃ 몰비: 23, 50)과 γ-alumina를 담체로 사용하여 촉매를 합성하였다. 합성방법은 CVD(화학기상증착법) 과 Dry Impregnation (건식함침법)방법이었다. CVD 방법으로 얻은 Fe/ZSM-5는 지지체로 사용된 ZSM-5의 SiO₂/Al₂O₃의 몰비가 작을수록, 즉 산점의 수가 많을수록 Fe 담지 량이 증가하는 것으로 보인다. 등온 환원 온도 400℃에서 수소 환원 양이 최대로 나타나며, 이는 보고되는 400℃에서의 최대 NOx 제거 반응 속도와 비례하는 것으로 나타난다.
