THE HISTOLOGIC FEATURES AND HISTOGENESIS OF MALIGNANT OVARIAN BRENNER TUMOR

Eight cases of malignant and 12 0f benign Bren- ner tumor are reported, patient ages ranged 31 69 and 39-53 years. The malignant tumor was bilateral in 6 0f 8 cases, and the benign in l of 12. The greatest diameter of the malignant tumors averaged around 11 cm, and the benign 10. Six of the malignant Brenner tumor patients died, one was lost to follow up, and one survived for 10 years. Pathologic and microscopic findings were pre- sented in some detail. Based on the analysis of the association between the histologic features and type of Mullerian epithelium, we believe that the so called Brenner tumor is in effect a tumor arising from the Mullerian epithelium with a tendency to differentiate into vaginocervical type epithelium.

Benign osteoblastoma of the occipital bone: Case report and literature review

We present a case of benign osteoblastoma of the occipital bone. Benign osteoblastoma is an uncommon primary bone tumor, which usually involves the vertebrae and the long bones. This tumor rarely develops in the calvaria, showing a preference for the temporal and frontal bones when it does. To the best of our knowledge, this case is only the eighth reported case of benign osteoblastoma confined to the occipital bone. A 20‐year‐old male presented with a mild tender mass lesion of the occipital area, just below the lambda. Plain X‐ray films and CT scans demonstrated an osteolytic mass surrounded by the sclerotic rim within the diploic space. MRI proved to be effective for the evaluation of the intracranial and intraosseous extensions of the tumor. However, it was very difficult to formulate a differential diagnosis against other osteoblastic tumors, or osteoid osteoma, in view of its radiological appearance. The final diagnosis was obtained by careful consideration of the histopathological characteristics of the tumor combined with its clinical and radiological features. Although generally regarded as benign, a complete resection is preferred over conventional curettage as this can guard against possible recurrence and malignant transformation.     

通过原生质体融合获得青霉素高产菌株

采用两株分别带有不同抗药性标记的产黄青霉原生质体以1:1相混合,用30％的聚乙二醇(MW6000)原生质体融合处理。将混和物涂布在补给有两种药物同时存在的高渗性分离培养基上,培养后获得异核体菌落。洗下异核体分生孢于继续分离在补给有两种药物同时存在的分离培养基上,得到了同时带有两种抗性标记的重组体。纯化后,进行抗性稳定性和摇瓶效价的测定,将一株具有双重抗性、摇瓶发酵效价较高的菌株作出发菌株,经诱变因子处理后,获得了一株43u7c—57菌株,在摇瓶中效价比生产菌株平均提高4.94％,该菌株在40吨发酵罐试生产后,发酵效价平均提高4.4％,产量则平均增加12.15％。     

Saponins from the roots ofPulsatilla koreana

From the roots ofPulsatilla koreana, three monodesmosides(pulsatilla saponins A, B and D) and two bisdesmosides(pulsatilla saponins F and H) were isolated. The structure of these saponins have been determined as hederagenin 3-O-α-L-rhamnopyranosyl(1→2)-α-L-arabinopyranoside(A), hederagenin 3-O-β-D-glucopyranosyl(1→4)-α-L-arabinopyranoside(B), hederagenin 3-O-α-L-rhamnopyranosyl (1→2)-[β-D-glucopyranosyl(1→4)]-α-L-arabinopyranoside(D), 3-O-α-L-rhamnopyranosyl(1→2)-α-L-arabinopyranosyl hederagenin 28-O-α-L-rhamnopyranosyl(1→4)-β-D-glucopyranosyl(1→6)-β-D-glucopyranosyl ester (F) and 3-O-α-L-rhamnopyranosyl(1→2)-[β-D-glucopyranosyl(1→4)]-α-L-arabinopyranosyl hederagenin 28-O-α-L-rhamnopyranosyl(1→4)-β-D-glucopyranosyl(1→6)-β-D-glucopyranosyl ester(H) on the basis of chemical and spectral studies. Pulsatilla saponin B is the first report of its presence in plants but saponins A, D, F, and H have recently been isolated from the same genusP. cernua.

男性慢性胃炎患者人格特征初探

本文采用卡氏十六种人格因素量表，对纤维胃十二肠镜和活体组织病理检查确诊，剔除可能影响调查的疾患之后的５６例慢性胃炎患者做了测查，结果与中国男性成人常模对照，提示男性慢性胃炎患者的主要人格特征有：严谨、保守、忧郁、紧张、顺从、依赖、有焦虑倾向，非内向个性，不属于心理不健康人群，而与消化性溃疡个性特征有所不同，但是，矫治其人格缺损及属必要。     

5种拟钉螺酯酶同工酶酶谱的比较研究

采用聚丙烯酰胺凝胶垂直平板电泳技术，对湖北和四川两省５种拟钉螺的酯酶同工酶酶谱进行比较研究，并以湖北钉螺作对照，５种拟钉螺酯酶同工酶共分离出８条酶带，酶谱可分成３区，即ＥＳＴ－１、ＥＳＴ－２、ＥＳＴ－３，其基本特征与钉螺显著不同，很容易通过酶谱将拟钉螺与钉螺区分开，同时，５种拟钉螺的酯酶同工酶酶谱之间均存在一定的差异，说明拟钉螺种间酯酶同工酶存在多态，而种间差异程度似与地域隔离的远近有关。结果提示拟钉螺酯酶同工酶的酶谱特征既有助于拟钉螺属的鉴定，又有助于拟钉螺近缘种的区分，从而对拟钉螺的分类有较大的参考价值。
