Conversely, the ducts of chronic pancreatitis may be atypical and pseudoinfiltrative as a result of acinar atrophy and fibrosis.

相反，慢性胰腺炎由于腺泡萎缩和纤维化，其导管会变得不典型和假浸润样。

The expressions of E-cadherin and α-catenin in specimens of 54 breast carcinomas and 21 normal breast tissues around tumor were measured by immunohistochemical method. Results In normal breast tissues, E-cadherin and α-catenin were expressed on cell membrance of ductal and acinic cells. No abnormal expressions were found in normal breast tissues. The abnormal expression rates of E-cadherin and α-catenin in breast cancer were 51.9% and 63.0% respectively.

结果 21例癌旁正常组织中，上皮钙黏蛋白和α-连接素均主要定位于腺泡或导管上皮细胞膜上，显示了细胞－细胞间交界和细胞轮廓，二者均表达正常；54例乳腺癌组织中上皮钙黏蛋白和α-连接素的异常表达率分别为51.9%和63.0%。

A portion of ductal cells and individual serous acinic cells of the minor salivary gland also expressed Fas not only in membranous but also in cytoplasmic pattern.

结果发现，在正常鼻咽粘膜表面及隐窝的假复层纤毛柱状上皮细胞胞膜、部分小涎腺的导管上皮和个别浆液性腺泡上皮细胞的胞膜和胞浆Fas阳性表达；鳞状化生上皮的表层细胞胞膜有Fas表达，但基底细胞未见Fas表达；浸润的淋巴细胞也不表达Fas.45.9%（17/37）的鼻咽非角化性癌Fas阳性，但只有不足10%的癌细胞胞膜微弱表达Fas。

There were 2 lobular carcinomas in situ, 2 gradually pipe carcinomas, 3 heavy degree atypical mazoplasias, 38 fibroadenomas, 36 mazoplasias, 9 cases of adenosis of mammary gland, 3 cystic hyperplasias, 1 skin purple.

结果：病理诊断原位癌2例，浸润性导管癌2例，重度不典型增生3例，纤维腺瘤38例，乳腺增生症36例，乳腺腺病9例，乳腺囊肿3例，1例皮下青紫。

The results suggest the expression of Nm23-〓 Protein is more often seen in the cases of adenosis with atypical hyperplasia than in the cases of carcinoma, the expression of Nm23-〓 might be a marker of adenosis with atypical hyperplasia in cases of FCD; Lower level of Nm23-〓 suggests in had a high metastatic potentiality in breast cancer.

在浸润性导管癌组中，有腋窝淋巴结转移组的Nm23-〓含量显著低于无液窝淋巴结转移组。结果提示：Nm23-〓蛋白在不典型增生上皮中的表达比癌组织更常见，Nm23-〓蛋白过度表达可能是乳腺上皮不典型增生的一个特征；在乳腺癌病例中，Nm23-〓蛋白表达与腋窝淋巴结状态有关。

Preliminary Identification of A Single Dominant Gene Conferring Resistance to Leafminer in Lycopersicon hirsutum Dunal;2. Biological characteristics of adult Opius caricivorae Fischer, a parasitoid of Liriomyza sativae Blandchard ;3. Opius caricivorae Fischer (Hymenoptera: Braconidae) is an important endoparasitoid of the vegetable leafminer, Liriomyza sativae Blandchard (Diptera: Agromyzidae) in China.

本文以检疫性害虫—美洲斑潜蝇 Liriomyza sativae Blandchard及其优势种天敌—黄腹潜蝇茧蜂opius caricivorae Fischer这一寄生体系为研究对象，对黄腹潜蝇茧蜂的毒液器官形态和超微结构、类病毒颗粒存在与否及其分布、毒液的蛋白组分及其对寄主的生理影响等进行了初步的研究，取得以下结果：(1)位于雌蜂腹部近背面的黄腹潜蝇茧蜂的毒液器官属于类型Ⅰ，由一个土黄色、锥状的毒囊、7个透明的椭圆形的毒腺和一个导管构成的，其中毒囊由发达的纵肌环绕。

There were some important discovery in structure character as the follows: in sarcotesta that materials making experiment, all possessed the structure of bandshape and like primary thickening meristem; sarcotesta possessed amphivasal vascular bundle and the vascular bundle that xylem distribute in two sied of phloem on inside and outside were discovered; new structure patterns of root that possessed more plentiful secondary cortex etc.

其中，发现外种皮中均具明显的似初生增厚分生组织的带状结构；且发现在外种皮的组织中具有双木维管束及周木维管束，发现了苏铁科植物根具较丰富的次生皮层等新的结构形式；在对比材料鳞秕泽米铁的羽片中发现了导管，这些在苏铁植物方面过去均未见有报道。

In an attempt to determine non-invasively the sino-atrial conduction time, we recorded the sinus node electric activity by placing bipolar electrodes at the level of the right atrium anteroposteriorly across the chest of the dog.

本实验采用成年狗，以6极心导管电极从颈外静脉插至上腔静脉与右心房交界处，能记录到一个在心电图P波以前19—26毫秒的&P前波&。通过夹除窦房结和高血钾等实验证明，&P前波&可与P波分离而存在，并随窦房结夹除而消失。
