고주파 열치료는 전극이 부착된 바늘을 이용하여 간암 병소 내에서 열을 발생시켜 조직의 괴사를 만들어 암세포를 파괴시키는 국소 치료법으로 최근 이에 대한 관심과 시행 건수가 증가하고 있으며 비교적 안전하고 상당히 효과적인 치료법으로 보고되고 있다. 아직까지 고주파 열치료 후 발생한 Clostridium 감염은 아직 보고된바 없는데 연자 등은 고주파 열치료를 시행한 간암 환자에서 Clostridium 감염에 의한 간농양이 발생한 예를 경험하였기에 보고하는

N/A To investigate the prevalance of cholelithiasis in liver cirrhosis, a retrospective study using biliary ultrasonography was performed in 222 patients with liver eirrhosis and in 177 controls. Gallstones were found more often in cirrhotic patients (13.5%) than in controls (5.6%) (p<0.05). Their prevalence was the same in both sexes. The prevalence of gallstone increased in decompensated liver cirrhosis (p<0.05). The prevalence was higher in HBs-Ag negative liver cirrhosis than HBs-Ag positive liver cirrhosis (p<0.01). The linear trend of increasing prevalence with increasing age in non cirrhotic group was not observed in patients with liver cirrhosis. This study confirms, by means of sonography, the high prevalence of cholelithiasis in liver cirrhosis in Korean adults.

불염여성에서 복강내액의 독성 유무를 알기 위해서 콤퓨터 정액 분석기를 이용하여 복강내액의 정자 활동성을 분석하였다. 연구대상은 자궁내막증 환자 14예와 자궁내막증이 없는 불염환자로부터의 복강내액 9예로 하였다. 연구방법은 건강인의 정자를 셰척 분리하여 대상환자의 복강내액과 Hams F10 배양액을 동량 흔합하여 (50%) 배양후 정자 활동성을 측정하였다. 정자 활동성의 감소는 배양전 0시간의 수치와 비교해서 1시간, 4시간 그리고 24시간후의 결과를 비교 분석하였다. 자궁내막증 제 1기 및 제 2기 환자와 자궁내막증이 없는 환자의 복수에서의 정자 활동성의 감소는 통계학적으로 의의있는 차이는 없었다. 그러나 자궁내막증이 심한 제 3기의 환자군에서는 의의있는 차이가 있었다(p<.05). 실험군간의 정자 활동성의 평균치 차이는 없었으나,각 군에서의 환자별 개인 성적은 정자 활동성이 현저히 감소한 독성있는 복강내액과 비독성의 복강내액을 쉽게 구별할 수 있었다. 결론적으로 정자 배양을 이용한 복강내액 독성 검사는 비교적 간단하고 경제적이므로 염상적으로 최근에 대두된 복강내 수정 치료법의 예비검사로서 유용할 것으로 사료된다.

Radiologic findings were analyzed in 338 cases with endoscopically proven duodenal ulcer. The results were as follows; 1} Male to female ratio in duodenal ulcer disease was 4 5: I, and occurrence rate was highest among thirties and forties. 2) In 114 cases with duodenal ulcer in active or healing stage proved by endoscopy, cor- rect diagnosis was made in only 54.4% of cases by radiologic examination. In g cases with duodenal ulcer scar proved by endoscopy, 4 cases(44.4%) was diagnosed as ulcer in active or healing stage by radiologic examination. From these findings, it is suggested that the initial diagnosis and decision of healing in cases with duodenal ulcer disease would have to be made by endoscopic examination.

Implantation rates remain low following human in vitro fertilization (IVF). Suboptimal culture conditions may limit the ability of embryos to hatch as blastocysts, and artificial opening of the zona pellucida has been proposed as a means to promote subsequent hatching (assisted hatching). In this study, assisted hatching (AH) by zona drilling using acidic Tyrode's solution was performed in 320 patients, due to their age of more than 38 years (group A), the thick zona pellucida (group Z; $ZP\geq0.18{\mu}m$), and failures in implantation more than 3 times in previous IVF-ET trial (group P). This study was designed firstly, to study the effects of AH on the outcomes of IVF-ET according to the indications and secondly, to verify the appropriate application of AH. The results were as follows; 1. There was no difference in pregnancy rate between AH group (26.6%) and non-AH group (26.5%). 2. Assisted hatching (AH) showed significantly higher pregnancy rate of the patients with thick zona pellucid a than those of the patients with age factor and with the history of repeated implantation failure. But in the patients with age factor only, AH resulted in higher pregnancy rate. 3. Interestingly, the patients with complex factors including zona factor (Z: 33.9%; ZA: 30.4%; ZP: 31.6%; ZAP: 21.4%) showed higher pregnancy rates than other complex factors excluding zona factor (A: 24.4%, P: 0%; AP: 10.8%). From these results, AH is more helpful to the patients with thick zona pellucida rather than patients with older age and/or previous repeated implantation failure.
