日本血吸虫虫卵在日本血吸虫病病理学上起重要的作用。所以,了解有关虫卵代谢方面的知识是更好了解发病机制的基础。在一种化学成分限定的培养基内培养血吸虫卵由单一卵细胞发育为一个毛蚴是严格研究其代谢的前提。作者(1983)已报道虫卵完全发育需要14种L-氨基酸(精氨酸、半胱氨酸、组氨酸、异亮氨酸、亮氨酸、赖氨酸、甲硫氨酸、苯丙氨酸、丝氨酸、苏氨酸、色氨酸、酪氨酸、缬氨 Schistosoma japonicum eggs play an important role in the pathology of schistosomiasis japonica. Therefore, understanding the knowledge about egg metabolism is the basis for better understanding of the pathogenesis. It is a prerequisite to strictly study the metabolism of Schistosoma japonicum eggs in a chemically defined culture medium that a single egg cell develops into a miracidia. The authors (1983) reported that 14 species of L-amino acids (arginine, cysteine, histidine, isoleucine, leucine, lysine, methionine, Serine, Threonine, Tryptophan, Tyrosine, Valine
