不典型脑转移瘤CT和MR的诊断分析

目的：提高CT与MR对不典型脑转移瘤的诊断准确性。方法：回顾性分析58例经临床手术证实的有完整资料的不典型脑转移瘤的CT和MR表现。结果：病变大部分位于幕上，有钙化者较多，约2／3有强化和水肿，且多发。部分有出血和囊变。结论：不典型脑转移瘤的CT和MR表现多种多样，多发者相对容易诊断，单发者诊断不易。颅外肿瘤的检查有助于鉴别诊断。肺部的影像学检查是必不可少的。

Promoting effect of the Chinese medicinal herb, wikstroemia chamaedaphne and tung oil extracts on carcinoma of the uterine cervix induced by HSV-2 or methylcholanthrene (MCA) in mice

The promoting effect of the Chinese medicinal herb, Wikstroemia chamaedaphne and Tung oil extracts (WC and HHPA) on carcinoma of uterine cervix induced by HSV-2 or MCA in mice was studied. The results showed that WC and HHPA extracts were not carcinogenic themselves. After carcinogen HSV-2 and MCA treatment, WC and HHPA were added separately. The inducing rates by HSV-2 increased from 7.4% to 21.1% and 26.3%, those by MCA increased from 56.5% to 82.8% and 84.4%. There was a significant difference between the combined groups and groups with HSV-2 or MCA only. The experimental results suggest that these two kinds of extracts play a promoting effect on carcinogenesis. The relation between the carcinogenesis of uterine cervix or nasopharynx and WC or HHPA extracts is discussed.
