The somatic hybrids usually showed specific bands and combined all the bands of both parents. In combinations, some new bands were detected, and occasionally specific bands of parents were lost, which indicated that chromosome recombination and exchange happened after fusion. Additionally, in some combinations, specific bands from leaf parent were detected, which revealed the plants were of putative hybrid origin, because leaf protoplast cannot redifferentiate by both single culture and co-culture.

体细胞杂种一般表现为具有双亲的特征带，且综合双亲的所有带，但在部分杂种中检测到了双亲都没有的新带，也发现有丢失亲本的特征带或共有带的现象，说明融合后染色体发生了重组和交换；有的引物只检测到叶肉亲本的特征带，根据柑橘叶肉细胞无论单独培养还是共培养均不能再生的事实，可推测其为体细胞杂种或二倍体叶肉亲本型胞质杂种。

Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.

流纹质岩石总体具富碱、富硅、富铝，贫钙、贫镁特征，其Rb、Th等元素的含量较高，而Ba、Sr、Ti、P等元素含量则明显偏低，并具显著的铕负异常（εEu=0.16'0.44），岩石的εNd值变化于-5.93~~-2.22.I、II旋回玄武岩和流纹岩在地球化学特征上均具明显变异。

Raynauds phenomenon, arthralgia/arthritis, fever, muscle involvement, swollen hands/sclerodactyly and abnormally elevated IgG and ESR levels were seen frequently in the disease course. Morbidity of pulmonary interstitial fibrosis was 40%. Renal involvement was not found in 15 cases of MCTD patients.

首发症状主要为雷诺现象(86.7％)，其次为关节痛／关节炎(13.3％)；临床表现中雷诺现象、关节痛／关节炎、发热、肌无力／肌炎、手指肿胀常见，实验室指标中IgG和血沉增高发生率高，肺间质病变发生率为40％，15例MCTD均无明显肾脏受累。

Followed two-compartment model, the biological half-life of chTNT-3-SL and (chTNT-3/B + SAv-SL) in rats was longer than that of free doxorubicin but shorter than sterically stabilized liposomes.

结果表明，两种主动靶向脂质体给药系统与固定Raji细胞的结合量均显著高于阴性对照组(P＜0.001)。

The tritocerebrum and suboesophageal ganglion show obvious GABA and 5-HT immunoreactivity.

后脑和咽下神经节髓质区均呈现明显的GABA和5-HT阳性反应。

Linear opacities appeared in 14d group and 28d group,bullae and pneumothorax were mainly in 28d group,the difference of appearance of two signs above had statistical significance(P＜0.05).The difference of appearance of ground-glass attenuation and consolidation had no statistical significance in sub-groups.Nodules and subpleural interstitial thickening did not appear in 3d group.

线状影出现于14d组及28d组，肺大泡和气胸主要见于28d组，上述两个征象出现的差异具有统计学意义(P＜0.05)；磨玻璃影和实变在各组中出现的差异无统计学意义；结节影和胸膜下间质增厚在3d组均未出现；蜂窝肺1只及牵引性支气管扩张2只都出现于28d组。3。

It has extensive uses no matter which kind of symptoms of spot and substratal skin, any age is applicable.

用面极为广泛，不论哪种斑症状、不论哪类基质皮肤、不论哪类年龄均可以使用

The results showed that photosynthetic rate, transpiration rate and stomatal conductance of Syzygium hancei Merr.et perry seedlings in the environment of sea sand are greater than in the environment of river sand.

通过对两种不同培养基质下红鳞蒲桃幼苗的光合生理日变化特征研究，表明在海沙环境中生存的红鳞蒲桃幼苗的光合速率、蒸腾速率及气孔导度比在河沙环境中生存的幼苗均较大。

A set of spectific primers was syn thesized according to HBV DNA sequence of Chinese strain, the whole X region was amplified by PCR method from the serum of 9 patients with chronic HBV infection , and then the PCR products were subcloned into pGEM Teasy vectors. Clones were randomly selected to be sequenced. Comparison of the cloned sequence was made to find the difference. After being compared, each sequence of selected clones is o f difference. The point mutation scattered through X region. Deletion mutations were detected in 19 clones of 37(51.4%), which caused different carboxyl endings of X protein. There is a hot region (after 123 aa code) where deletion mutation frequently happens.

以中国株HBV基因序列为依据，设计特异性多聚酶链反应引物，自9例慢性HBV感染患者血清中扩增HBV X基因，克隆入pGEM Teasy质粒，随机挑选克隆进行D NA测序以确定病毒的变异程度。37例测序结果提示来源于不同患者HBV X基因序列高度保守，但每个序列均不一致。X区除了存在广泛的碱基点替换突变外，序列的缺失突变占测序克隆总数的51.4％（19／37）；氨基酸缺失及移框突变多发生于123位氨基酸残基之后，可导致X蛋白多种羧基端形式。

The second group are the mixtures of Jurassic coal-formed oils and Cretaceous-derived oils. The carbon isotope, n-alkanes and isoprenoids compositions of these oils are similar to core extracts from Jurassic coal measures. However, sterane and terpane compositions of these oils show affinity to Cretaceous source rocks. It is deduced that coal-formed oils dissolved the biomarker-rich Cretaceous bitumen of relatively low thermal maturity, and overprinting occurs during oil migration.

第二类原油具有侏罗系煤系烃源岩与白垩系湖相泥质烃源岩混源的特点，这类原油的碳同位素组成、正构烷烃分布特征和姥植比等均表现出煤成油的特征，但甾、萜烷烃类化合物组成与白垩系烃源岩接近，推测是由于侏罗系煤成油在向上运移成藏过程中，受到成熟度相对较低、生物标志物相对丰富的白垩系烃源岩的浸析作用所致。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
