比较了 4株不同云芝菌PVC0、PVC1、PVC2和PVC3对含有美拉德反应色素、碱降解色素及焦糖色素的模拟废水的生物降解脱色能力及云芝多糖生产能力。

Patches lighter in color than the normal skin may be completely depigmented or have lost only part of their pigment. This is an important distinction, since certain conditions are or may be hyposigmneted such as tinea versicolor, nevus anemicus, leprosy, hypomelanotic macules of tuberous sclerosis, hypomelanosis of Ito, seborrheic dermatitis, and idiopathic guttate hypomelanosis.

比正常皮肤颜色浅的斑片可能是完全或部分丧失了色素，这是一个重要的特征，因为某些疾病就可能是色素沉着减少的，如花斑癣、贫血性痣、麻风、结节性硬化性低色素性斑疹、伊藤黑素过少症、脂溢性皮炎、特发性点滴状色素减少症。

METHODS: The authors measured MPOD with heterochromatic flicker photometry, serum lutein and serum zeaxanthin by high performance liquid chromatography, and central foveal retinal thickness by optical coherence tomography in 176 patients (age range, 18-68 years) with typical forms of retinitis pigmentosa; 37 (21%) of these patients had cystoid macular edema by OCT.

作者对176例（年龄范围18-68岁）典型视网膜色素变性患者进行以下测量：采用异色闪烁光度法测量黄斑色素光密度，高效液相色谱法测量血清脂色素和血清玉米黄质，和光学相干断层扫描法测量中心凹中央视网膜厚度；其中37例（21％）患者OCT检查有黄斑囊样水肿。

The results indicated that 40% ethanol and water can dissolve Berberis heteropoda pigment better; the pigment is stable in acidic condition; iron ion can increase the absorbency of the pigment; the influences of reducing agent is greater than oxidizer＇s.

结果表明，小檗色素在40％的乙醇溶液及水中的溶解效果最好；在酸性条件下色素较稳定；铁离子对其有增色作用；氧化剂、还原剂对色素稳定性均有影响，其中以还原剂影响较大。

The paper studies the color range of papaver rhoeas red pigment under pH values, and compares it with the other indicators by the acid-base titration.

本文研究了虞美人色素在不同pH值溶液中的颜色变化，并通过虞美人色素和其它指示剂进行酸碱滴定的比较，结论为：虞美人色素能准确指示酸碱滴定的终点，其变色范围pH 6.33~8.25，颜色由紫红色变为棕色

In the seedlings time, the content of chlorophyll decreased by the deficiency of B, but the content of chlorophyll in the high efficiency cultivar decreased slowly than that of the low efficiency cultivar. This suggested that the leaves of the high efficiency cultivar can capture more light energy and the photosynthetic rate of the high efficiency cultivar decreased slowly. In the bolting time and blooming time, after two weeks of B deficiency treatment, the content of chlorophyll in the top leaves of the high efficiency cultivar decreased, and in the late time, the content of chlorophyll decreased slowly. But, the content of chlorophyll in the bellow leaves of the two cultivars had little changes. The reason may be that B in the high efficiency cultivar distributed to the propagative organ in the late growth, and the leaves were short of B.

苗期，缺硼导致甘蓝型油菜色素含量降低，且高效品种色素含量下降的幅度小于低效品种，表明营养生长阶段，同等程度的缺硼条件下，高效品种叶片对光能的收集能力以及光合速率下降的程度相对较小；苔期和花期，在两周的缺硼处理后，高效品种上部叶色素含量依然呈下降趋势，但随着生育期的推移，其下降幅度减小；而高效品种下部叶和低效品种叶片含量变化不大，可能是甘蓝型油菜进入生殖生长阶段后，高效品种将硼更多地分配到繁殖器官，而其叶片却承受了相对较大的缺硼胁迫。

IntroductionSmooth surfaced endoplasmic reticula contain plenty of cyto-chromes, which are mainly cytochrome P450 ( CYP450 ) and b5 and are very important in the process of the biotransformation of exogenetical fat - soluble compounds and the metabolism of some endogenetical matrices, such as bile acid forming^ bile pigment metabolism and steroid synthesis.

CYP450是50年代中期Williams和Klingeberg发现、60年代初木村和佐藤验证的一类b族细胞色素，由于还原型细胞色素与一氧化碳结合后在光谱的450nm处具有最高吸收峰，因而命名为CYP450以别与其它b族细胞色素，P是英文Peak的缩写。

At the 10th day after cultivation, the visual pigment immunoreaction was suffusive in the whole cell membrane and apical process; while at the 30th and 40th day, it gathered at the membrane of apical process or one pole of the cells.

体外培养10 d时，视色素弥漫地分布于整个细胞膜及顶端突起；培养20 d时视色素逐渐向顶端突起或细胞的一端集中；到培养30、40 d时，视色素聚集于顶端突起或细胞的一端，呈现极性分布特征。

PONI skin health research centre, with advanced skin care technology and causes skin pigment, successful research and development of a "'8 'black-suppression, the corresponding treatment and conditioning" technology, not undermine, not suppressed, does not damage the ecology of the skin Under the circumstances, the skin pigment formation of a smart decomposition, hypnosis pigment cells, skin in a relatively short time, reaching Suji elegant, Whitening Source lucent effect, lasting effect, the relative safety of similar products increased 68 percent.

Diagnosis/testing. A diagnosis of ocular albinism is probable in the presence of congenital nystagmus, iris translucency, and significant hypopigmentation of the ocular fundus periphery in males with normal skin pigmentation and foveal hypoplasia, reduced visual acuity, and aberrant optic pathway projection, as demonstrated by crossed asymmetry of the cortical responses on visual evoked potential. X-linked inheritance is documented by either a family history consistent with X-linked inheritance or the presence of typical carrier signs (irregular retinal pigmentation and partial iris transillumination) in an obligate carrier female.

诊断/检测。对于皮肤色素沉着正常、中央凹发育不全、视敏度降低以及视径投射异常（VEP，表现为视觉诱发电位中皮层反应的交叉不对称）的男性患者，当存在先天眼球震颤、虹膜半透明以及显著的眼基底层边缘色素减退的症状时，可被疑似诊断为眼白化病。X连锁性遗传则以存在与X连锁遗传一致的家族病史，或在一个应当为携带者的女性中存在典型的携带者迹象（视网膜色素沉着不规则以及部分虹膜透射）而被确认。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
