斑点

It is an unusual clinical presentation of speckled lentiginous nevus which must be differentiated from benign pigmented lesions due to a potential for malignant changes.

此例为斑点状小痣样母斑临床上较特殊的表现，且因其有恶性变化的可能，故须与其他良性色素病灶作鑑别。

Results The relevant spots of Radix Paeoniae Alba,Rhizoma Chuanxiong and Radix Puerariae Lobatae on TLC plates were clear without the interference of the blank control.

Results Mottling and patchy infiltrats were observed in 42 patients, irregular shape cavities in 41 patients, 28 patients had satellity lesions, 8 had fibrotic stripes, 10 had mottling califacations, 2 had lymphy node enlargement.

结果得到42例均见斑片状高密度灶影，其中41例不规则空洞影，4例与支气管相通；28例卫星灶影，8例纤维索条影，1例仅见小斑片状影伴卫星灶影，10例见斑点状钙化影，2例淋巴结肿大等。

Results We obtained a lysogenic bacteriophage MZTP01with clear plaque and 1 mm diameter. Fragment D with 2362bp (Genebank No. AY639599) was obtained after the phage DNA hydrolyzed by HindⅢ/EcoRⅠ. Among fragment D, the pep gene with molecular weight of 47 kDa and length of 1101bp was cloned and expressed. Recombinant M15 (pQE30pep) was built and overexpressed in Escherichia coli with a 47kDa clear band. At the same place a clear band was observed by Western blot. Judging from the time course expression, we could conclude that PEP protein produced at 1 hour after induction and then increased gradually. PEP protein was mainly in the form of inclusion body in the recombinant and slowed the growth speed of host. Homologous comparison of PEP protein from phage MZTP01 with other PEPs from BLAST were that phage MZTP01 PEP protein had 100% homologe with that of Escherichia coli K12, and most of others took the similarity in the range between 37%~84%.

诱导获得的溶原性噬菌体MZTP01斑点清晰，直径约1mm，成斑时间12h；从噬菌体基因组DNA双酶切(HindⅢ/EcoRⅠ)片段中回收长度为2362bp的D片段(Genbank登录号： AY639599)，又从D片段中克隆了长度为1101bp、编码367aa、分子量为47kDa的pep基因，表达载体M15(pQE30pep)在大肠杆菌(Escherichia coli， E.coli)中表达获得了47kDa的清晰表达带，在1h 时开始产生蛋白并有逐步上升的趋势； Western blot 也在47kDa处得到一条清晰的条带；可溶性分析表明PEP蛋白在重组菌株中是以不可溶的包含体形式存在的，该蛋白的产生明显地抑制了宿主的生长速度；噬菌体PEP氨基酸序列之间的同源性比较表明，噬菌体MZTP01 PEP蛋白与来自E.coli K12噬菌体的PEP蛋白的同源性程度最大。

Based on using those specific PCR primers, a unique 190 bp hand was obtained by PCR amplification from genomic DNA of Venturia inaequalis of apple and it can be accurately distinguished from patbogens of Alteraria mali, Marssonia mali and Podosphaera leucotricha, the common apple leaf spot diseases.

利用这对引物能从苹果黑星病菌基因组DNA中扩增出一条分子量为190bp的特异性条带，准确地把苹果斑点落叶病、苹果褐斑病和苹果白粉病等常发性苹果叶斑病害区分开。

Although atypical lymphocytes are often present in cases of either CMV or EBV infection, the appearance of atypical lymphocytes in CMV infection may be delayed for several weeks, as appeared to happen in this case, and may persist for months.2 During the course of CMV infection in many patients, a rash develops that has been described variably as macular, papular, morbilliform, and scarlatiniform.
