Antitumor effect of the seashell protein Haishengsu on Ehrlich ascites tumor: an experimental study

The aim of the study was to investigate the in vivo effect of the seashell protein Haishengsu (HSS) on Ehrlich ascites tumor. Mice were inoculated with Ehrlich ascites tumor cells and randomly divided into three HSS groups and a control group. The survival times in the three HSS-treated groups was longer than in the control (P < 0.01) and the increased life span in the high-dose HSS group was greater than in the lower-dose groups (P < 0.05). In comparison with control group, the mice receiving pretreatment of HSS had longer survival times and greater life spans following inoculation of the ascites tumor (P < 0.05). HSS therefore prolongs survival times and increases the life spans of mice bearing Ehrlich ascites tumor. Pretreatment with HSS also diminishes the detrimental effect of Ehrlich ascites tumor on the prognosis of these animals.
