Dwarfism stunted growth . this may be due to genetic mutation , causing gibberellin deficiency 矮態(tài):植物生長受到限制形成的植株形態(tài)矮小,可能是由于基因突變?cè)斐傻某嗝顾厝狈σ稹?
In humans , severe and prolonged psychological stress can cause growth to stop in children , a rare syndrome called psychogenic dwarfism 人類兒童要是經(jīng)歷嚴(yán)重而長期的心理壓力,發(fā)育會(huì)停止,那是一種罕見的病,叫作心因性侏儒癥。
2 a number of drastic mutations can produce this kind of dwarfism , ranging from a defect in a gene that releases growth hormone to defects in genes that result in damage to the pituitary gland 注 as a whole 4多種劇烈的突變都可能導(dǎo)致這種侏儒癥,其中包括從釋放生長激素的一個(gè)基因的一個(gè)缺陷,到導(dǎo)致整個(gè)垂體損害的多個(gè)基因的多個(gè)缺陷。
Ancient egyptian society had a strong code of ethics and commandments to be respectful towards dwarfs , the crippled and blind . depictions of dwarfism in tomb and vase paintings , statues and other art forms are numerous and indicate that dwarfs were employed as personal attendants , animal carers , jewellers , dancers and entertainers 在埃及發(fā)現(xiàn)至少有50座墓碑銘,以及眾多壁畫雕像等眾多古埃及文物上對(duì)侏儒的生活和形象細(xì)致的描繪,侏儒在當(dāng)時(shí)還被認(rèn)為擁有諸如驅(qū)趕毒蛇這樣的神奇力量。
Growth and development of animals were regulated by many factors including gene , environment , nutrition and endocrine . in endocrine system , growth hormone ( gh ) always taks up a centerlly regulative place . previous studies have shown that patients with gigantism or dwarfism have abnormal high or low plasma gh levels , respectively , and animals treated with exogenous gh markedly improved its growth . therefore , it is reasonable to enhance the levels of gh in plasma by some techniques will result in improvement of animal production performance 在內(nèi)分泌系統(tǒng)中,盡管任何一種內(nèi)分泌激素都不能單獨(dú)地調(diào)控動(dòng)物全部生長和發(fā)育過程,不過生長激素在其中仍占據(jù)著中心調(diào)節(jié)作用的位置。已知,巨人癥患者生長激素水平極度的升高,而侏儒癥患者的生長激素水平則顯著地降低,同時(shí),注射外源性生長激素可明顯地提高動(dòng)物的生長速度,改善了動(dòng)物的胴體組成。
Dr chahira kozma , of georgetown university hospital , washington , has used inscriptions and representations on tomb and temple walls , papyrus documents and other objects , as well as human remains , to see how achondroplasia , a cause of the most common type of dwarfism , was regarded in ancient times 據(jù)每日電訊12月28日?qǐng)?bào)道,通過對(duì)古代的銘神殿文獻(xiàn)資料和古人類遺骸的研究,美國華盛頓州喬治敦大學(xué)醫(yī)院的科茲馬博士指出,侏儒們?cè)诠虐<吧鐣?huì)受到尊重,享有較高的社會(huì)地位。
