ABSTRACT
Objective To evaluate the surgical treatment of old patients with acute perforated gastroduodenal ulcer. Method The age, complications, duration of the disease history, operative method, systemic inflammatory response syndrome (SISR) and multiple organ dysfunction syndrome (MODS) in 89 old patients with acute perforated gastroduodenal ulcers were analyzed retrospectively. Results Simple closure operation was performed in 78 cases and subtotal gastrectomy in the other 11 cases. Twelve patients died. The mortality and complications rate were significantly lower in the patients less than 70 -year old than those in the patients more than 70-year old (P
ABSTRACT
The immunoregulatory effects of some anti-cancer drugs have important role in their anti-tumor mechanisms. Our results showed that doxorubicin (DXR) of 0.04 mg ?L-1 could enhance the interleukin 2 (IL-2) release and induction of lymphokine-activated killer (LAK) activity of human fetal thymocytes(HFT). Higher concentration of this drug (4 mg ?L-1) exhibited inhibition on IL-2 release but no effect on LAK activity. These data suggest that lower concentration of DXR have some immunopotentiation effects on HFT.
