Abstract

Absorption and fluorescent cytophotometry techniques were applied to studies of RNA, glycogen and its fractions in hepatocytes of patients with hard mechanic trauma, both with and without endointoxication. For measuring RNA and glycogen contents, slides were stained by gallocyanin-chromalum or underwent fluorescent PAS-reaction, respectively. The repeated aspiration biopsy material was used for investigation of RNA and glycogen contents in dynamics. A quick increase in RNA content took place at the first stage (within the first 3 days) of traumatic illness of both the groups of patients. At the second stage of illness the hepatocyte RNA content in patients without endointoxication was seen to decrease to the initial level, whereas that in patients with endointoxication increased from the initial level by 36%. At different stages of illness the total glycogen content is changed insignificantly in the course of illness, but its labile fraction decreases to 70% of the total glycogen in patients with endointoxication. The increase of hepatocyte synthetic activity and the maintenance of the normal glycogen level may suggest a sufficient compensatory possibility of the liver, in spite of a high functional load under endointoxication.

摘要

采用吸收和荧光细胞光度测定技术,对有或无内毒素血症的机械性重伤患者肝细胞中的RNA、糖原及其组分进行研究。为测定RNA和糖原含量,玻片分别用间苯三酚二甲酸染色液或进行荧光PAS反应。采用重复穿刺活检材料动态研究RNA和糖原含量。两组患者在创伤性疾病的第一阶段(前3天内)RNA含量迅速增加。在疾病的第二阶段,无内毒素血症患者的肝细胞RNA含量降至初始水平,而有内毒素血症患者的肝细胞RNA含量则较初始水平增加了36%。在疾病的不同阶段,总糖原含量在病程中变化不显著,但内毒素血症患者糖原的不稳定组分降至总糖原的70%。尽管内毒素血症时功能负荷较高,但肝细胞合成活性的增加和正常糖原水平的维持可能提示肝脏具有足够的代偿能力。
