<br /><br /><h2></h2><br />British Journal of Industrial Medicine , Toxicologic Pathology , Toxicology and Applied Pharmacology , Arnott DG, Doniach I The impact of compounds allied to resorcinol upon the uptake of radioactive iodine I by the thyroid of the rat. IARC evaluated the carcinogenicity of resorcinol in and concluded that there aren't any epidemiological knowledge relevant to the carcinogenicity of resorcinol in humans and that the evidence of its carcinogenicity in animals is inadequate; thus, resorcinol is not classifiable as to its carcinogenicity to people. JECFA assessed the hazards from using resorcinol as a meals flavouring agent and concluded that this use is of no safety concern. Overall, the research usually are not enough for a statistical extrapolation method based on the EU Technical Guidance Document EC, a.<br /><br />No resorcinol-related macroscopic findings, organ weight, or opposed microscopic target organ effects had been noticed within the F 0 and F 1 parental animals. The F zero and F 1 females continued to receive the resorcinol all through mating, gestation, and lactation and thru the day of euthanasia for study design, see Appendix 7. There were no F 0 and F 1 parental resorcinol-related deaths or scientific findings in the course of the weekly detailed physical examinations. In controls and the excessive-dose group, a qualitative histopathological evaluation of the brain forebrain, midbrain, and hindbrain was additionally carried out for the aforementioned animals RTF, There were no antagonistic effects regarding reproductive efficiency, mortality, and physique or organ weights.<br /><br /><h3></h3><br />The organisms had been exposed to the take a look at concentrations for 96 h. Biological observations were performed daily.<br />The tolerable intake of 0. It is subsequently attainable that these neurological effects are as a result of acute effect of the gavage administration. CNS effects in humans and animals have been related to acute exposure to resorcinol.<br />Fifty per cent of survivors had been sacrificed 1 week later, and blood and urine samples were taken. Resorcinol confirmed a concentration-dependent increase in labelling index [ 3 H]thymidine , acanthosis, and papillomatosis. After utility of an ointment containing To study the goitrogenic exercise of resorcinol, female Wistar rats were treated twice day by day for 28 days by rubbing 6 g of an ointment containing Increased thyroid gland weights 2.<br />In follow, nonetheless, the incidence of sensitization appears to be low. In animal studies, the toxicological results reported to be attributable to administration of resorcinol embody thyroid dysfunction, irritation to skin and eyes, CNS effects, and altered adrenal gland relative weights. After topical use of excessive concentrations of resorcinol, CNS disturbances, such as dizziness, vertigo, confusion, disorientation, amnesia, or tremors, or red blood cell changes, such as methaemoglobinaemia, haemolytic anaemia, haemoglubinuria, or cyanosis, have been reported. One factor rising potential poisonous effects is the application of resorcinol to injured pores and skin.<br /><br />Other pores and skin effects had been hyperplasia, hyperkeratosis, irritation, and sebaceous gland hyperplasia, whereas there have been no systemic therapy-associated lesions. With resorcinol, several initiation—promotion research with hamsters Maruyama et al. Female Syrian golden hamsters 10—20 per group were handled with two subcutaneous injections of. In a research carried out by Hasegawa et al.<br />Although thyroid results are a big finish-level in each human case-studies and animal research, there is a lack of consistency in the results in the animal studies. Resorcinol brought on no adverse effects in several replica and developmental toxicity research in rats and rabbits. Resorcinol is not thought of to be genotoxic.<br />In one other study, male F rats had been handled with three intraperitoneal injections of three-methyl-. Based on the research of Yeung et al.<br /><br /><h1></h1><br />For the benthic and terrestrial compartments, the obtainable toxicity knowledge can't be considered adequate for a quantitative threat characterization. However, these compartments are much less relevant for resorcinol, due to marginal releases and emissions to these compartments in addition to a very low potential for adsorption of resorcinol to organic matter.<br />According to the results obtained, Daphnia magna is essentially the most sensitive organism, and resorcinol could be classified as acutely toxic only to Daphnia. However, this value is questionable to be used as a limit value in danger evaluation this is the very best concentration examined in this study , and the NOEC could be significantly higher than said in the study. In the ambiance, resorcinol is quickly degraded half-life about 2 h by reaction with photochemically produced hydroxyl radicals. Under cardio conditions, resorcinol proved to be readily biodegradable in a take a look at performed in accordance with OECD TG C, and it is likely to be biodegraded beneath anaerobic situations.<br />Different studies carried out with rats and mice gave no increase in the micronucleus formation in bone marrow cells. Bone marrow smears have been prepared at 30 h, and polychromatic erythrocytes per animal were scored Gocke et al. An interim sacrifice at 15 months gave no distinction in haematology, clinical chemistry, or other medical pathology parameters and no elevated incidence of neoplasms or non-neoplastic lesions. Also, at final sacrifice, there was no proof of carcinogenic activity in males or females of both species.<br />There are differences in thyroid physiology between humans and animals. The weight of proof suggests that rodents are more delicate to thyroid results than people.<br />The acute dermal toxicity of resorcinol was studied in male albino rabbits Koppers Company, Signs of intoxication included salivation, tremors, and convulsions, and handled skin areas showed slight erythema and extreme dryness. Mean data for three donors and sixteen replicates indicate a plateau in receptor fluid focus between 24 and forty eight h, as mirrored by cumulative absorption values of 1.

中文中有那么多好听的花儿名字,英文的对应名称又是怎样的呢?是不是都是些又长又拗口的拉丁文学名?其实有很多花儿的英文名称都很美哦,一起来看看。  满天星 Baby's breath  “婴儿的呼吸”,这样的名字从口中读出来,都有种温馨甜蜜的意味。 [http://ask1.cn/ 点击更多] ,这种花的学名是Gypsophila,这个词可就半点浪漫意味都没了。  牵牛花 morning glory  在我们眼中娇羞如小家碧玉的牵牛花,英文名称居然如此大气而庄严,真让人有几分诧异。这样看来,用牵牛花的另一个名称“朝颜”来对应morning glory,会更匹配一些。同样,它的学名,旋花科植物Convolvulaceae,看上去就没那么诗意了。  水仙 narcissus/daffodil  narcissus这个名字来源于希腊神话中的美少年Narcissus,由于痴恋自己在河中美丽的倒影而憔悴致死,死后化作水仙花。因此我们常说的“自恋”英语中就是narcissistic;narcissus这个词是“水仙花”的总称,而daffodil指的是其中的一种,黄水仙。英国著名湖畔派诗人华兹华斯就有一首脍炙人口的优美小诗《Daffodil》。  勿忘我 Forget-me-not  英文和中文刚好相互对应。原名是希腊文,意为“老鼠的耳朵”,因为勿忘我的叶子长的像老鼠耳朵。更常用的这个forget-me-not最开始是从法文名ne m'oubliez pas(别忘记我)直接翻译过来的。  木槿 Rose of Sharon  《诗经》中曾将美貌女子比喻成木槿:有女同车,颜如舜华。“舜”就是木槿。英文名看上去很奇怪,因为最初将圣经翻译成英文时,译者把希伯来语中的“木槿”一词翻错了,于是就出现了rose of sharon这个名字。  白玉兰 magnolia  上海市的市花是白玉兰。这个词小编一直觉得相当拗口,总是读成mangolia,囧,大家不要读错啊。  萱草 Day lily  萱草又称忘忧草。古时候由于母亲居住的地方,门前总是种满萱草,所以用“萱堂”来指代母亲。这是一种寄托思念的花,在古老的《诗经》中同样出现过:焉得谖草?言树之背。愿言思伯,使我心痗。其中“谖草”就是萱草的古称。英文名day lily来自希腊语,希腊语的原意是“day”和“beautiful”。  康乃馨 carnation  看得出来,康乃馨的名字是从英文音译过来的。大家都知道康乃馨是从给妈妈的花,但是不同颜色的康乃馨也有不同的含义,在法国,紫色康乃馨是献给死者的花,而且在讲法语的国家,康乃馨代表的是不幸。送给妈妈的康乃馨应该是粉红色。传说这种花是圣母玛利亚的眼泪灌溉出来的,所以代表了至纯的母爱。康乃馨的学名在希腊文中的原意是heavenly flower。母亲节快到了,大家是不是要给自己的妈妈准备一束粉色康乃馨呢?<br /><br /><br />
