COMPARATIVE STUDIES ON THE TOTAL PIGMENT AND PIGMENT COMPONENTS OF GOLDFISH

用色谱和光谱两种方法对金鱼总色素和色素组分进行了研究。研究结果表明,红鲫、草金鱼和红龙睛等红色金鱼总色素光谱在可见光区(472nm附近)有一个吸收峰,黑鲫和黑龙睛等黑色金鱼在可见光区(450nm和472nm附近)有两个吸收峰出现,且红色金鱼所含色素组分以红色(虾青素)为主,黑色金鱼所含色素组分以杏黄色和橙色为主,其他色素组分为辅。金鱼黑色色斑形成是由于黑色素存在时,其他各色素组分的颜色被掩盖的结果;金鱼其他各种色斑的形成则是由于其体内各色素组分以不同比例相互搭配组合的结果。亲缘关系越近的金鱼其总色素组成就越相似,红鲫和黑鲫均含有四种近乎相同的色素组分,红龙睛和黑龙睛均含有六种近乎相同的色素组分,草金鱼虽也含有四种与红鲫和黑鲫相近的色素组分,但Rf值略有差异。据此推测,红鲫和黑鲫、红龙睛和黑龙睛可能分别具有较近的亲缘关系,而草金鱼则可能是介于黑鲫和龙睛鱼之间,且与黑鲫具有较近的亲缘关系。该研究有望为金鱼增色饵料的研制与开发提供理论依据,使金鱼的观赏价值和经济价值得到进一步提高。The study was conducted to investigate the total pigment components of different breeds of goldfish by spectrophotometer and thin-layer chromatography.The results showed the spectrum of total pigment of Red color crucian.Grass goldfish and Red Dragon-eye had one absorption peaks in visible region(472nm). The spectrum of total pigment of Black carp and Black Dragon-eye had two similar absorption peaks in visible region(450nm and 472nm).The pigment components of different breeds of Red color goldfish were mainly Red pigment(astaxanthin). The pigment components of different breeds of Black color goldfish were mainly apricot or orange pigment.The black spots of goldfish may be formed when melanin covered other pigment,other color spots may be formed when the pigment component of all kinds were mixed in proper proportions.The more the relation of color spots is close,the more the total pigment component is similar.Red color crucian and Black carp had same pigment components of four kinds,Red Dragon-eye and Black Dragon-eye had the same pigment components of six kinds,although there are four pigment components,which are close to the ones in Red color crucian and Black carp in the body of Grass goldfish,but Grass goldfish's RF has slight difference with Red color crucian and Black carp.As above,Red color crucian and Black carp,Red Dragon-eye and Black Dragon-eye probably are close relatives,respectively,and the category of Grass goldfish may possibly fall between Black carp and Dragon-eye,which has a closer relative with Black carp.This study will give help to the research and development of goldfish color-adding diet and further enhancement of goldfish ornamental value and market value

Literature review on family influence on smoking behaviour among adolescents

Background: Smoking has long been one of the principal causes for morbidity and mortality and is ranked as the third leading cause for preventable health deaths in the world, posting serious threat to public health. Most smokers start smoking during adolescence. Adolescence describes teenagers aged 13-19 years old which can be considered as the transitional period from childhood to adulthood, about 88% of adult smokers who smoke daily started their smoking behavior by age of 18 years old and 68.2% of smokers started smoking below age of 20 in Hong Kong. Therefore, there is an urgent need to direct the public health effort towards the prevention of smoking in adolescents. It has been found that family has important influences on smoking behavior among adolescents. Objective: The objective of this review is to examine the effect of family influences on adolescents smoking behavior, particularly the association of parenting style, parental smoking and adolescent smoking behavior. Methods: he online databases PsycINFO, Medline and EMBASE were searched by using keywords “adolescents smoking” or “youth smoking” and “family influence” or “parental influence”. The last search was done on 10th August, 2013. Total 13 English articles, of which 10 were cross-sectional studies and 3 were longitudinal studies, were included in this review. Results: Literature showed authoritative parenting style could reduce the risk of smoking among adolescents; all studies showed authoritative parenting style, disapproval to smoke with higher level of parental monitoring could reduce risk of regular smoking behavior among adolescents. On the other hand, results from articles examining the association of parental smoking and smoking behavior among their children were almost homogenous. Adolescents who lived with smoking parents were more likely to initiate the smoking behavior compared to those with non-smoking family members. Meanwhile, studies showed adolescents from single-parent families were more likely to smoke when compared with those came from complete family. A negative association between single parent and daily smoking was observed among the adolescents. Conclusion: Future campaigns on smoking prevention should increase the involvement of family members, encourage parents to quit smoking and act as role model to their children; parents are suggested to practice authoritative parenting which will increase the acceptance of adolescents to their rules and suggestions and thus, avoid them from smoking. On the other hand, adolescents from single-parents are more likely to attain smoking and should increase awareness. More local researches, with randomized control trial studies, are needed in the future to examine family influences that fit the situation in Hong Kong. The aim of campaign is to further decrease smoking prevalence in adolescents.published_or_final_versionPublic HealthMasterMaster of Public Healt

COMPARATIVE STUDIES ON THE TOTAL PIGMENT AND PIGMENT COMPONENTS OF COLOR CARP

用光谱和色谱两种方法对锦鲤的总色素和色素组分进行了研究。研究结果表明,红色锦鲤、乌鲤和绯写锦鲤总色素光谱在可见光区(448nm和470nm)有两个完全相同的吸收峰,黄写锦鲤和昭和三色锦鲤总色素光谱在可见光区(445nm和472nm附近)有两个相近的吸收峰,锦鲤所含色素组分均以杏黄色或橙色为主,其他色素组分为辅。锦鲤黑色色斑是由于黑色素存在时,其他各色素组分的颜色被黑色所掩盖;锦鲤其他色斑的形成则是由于其体内各色素组分以不同比例相互搭配组合的结果。亲缘关系越近的锦鲤其总色素组分就越相似,红色锦鲤和乌鲤均含有六种相同的色素组分,绯写锦鲤除杏黄色和橙色色素组分与前二者的同色色素组分Rf值不同外,其余四种同色色素组分的Rf值均相近;黄写锦鲤与昭和三色锦鲤分别含有三种和四种色素组分且Rf值差异显著。据此推测,红色锦鲤、乌鲤和绯写锦鲤可能具有较近的亲缘关系,而黄写锦鲤、昭和三色锦鲤与前三者之间可能具有较远的亲缘关系。该研究有望为锦鲤增色饵料的研制与开发提供理论依据,使锦鲤的观赏价值和经济价值得到进一步提高。The study was conducted to investigate the total pigment and pigment components of different breeds of color carp by spectrophotometer and thin-layer chromatography.The results showed that spectrum of total pigment of Red Color Carp and Black color Carp and Black Spot-Red color Carp had two same absorption peaks in visible lregion(470nm and 448nm).The spectrum of total pigment of Black Spot-Yellow color Carp and Black-Blue-Red Spot-color Carp had two similar absorption peaks in visible region(445nm and 472nm).The pigment components of different breeds of brocaded carp were mainly apricot or orange pigment.The black spots of color carp may be formed when melanin covered other pigment,other color spots may be formed when the pigment components of all kinds were mixed in proper proportions.The more the relation of color carp is close,the more the total pigment component is similar.Red color Carp and Black color Carp had same pigment components of six kinds,there were similar Rf values of four same color pigment components for Black Spot-Red color Carp as compared with both of the former and there were different Rf values of two same color pigment components for the latter in comparison with both of the former.Black Spot-Yellow color Carp and Black-Blue-Red Spot-color Carp had three and four pigment components respectively,and the difference of their Rf values was notable.As above,Red color Carp and Black color Carp and Black Spot-Red color Carp probably are close relatives,and the former and Black Spot-Yellow color Carp of Black-Blue-Red Spot-color Carp probably are distant relatives.This study will help the research and development of color carp color-adding diet and further enhancement of brocaded carp ornamental value and market value.广东省科技计划项目(2002C20304);; 广州市科技攻关重点项目(2002Z2-E0102)资
