Objective To study the effects of complex polysaccharides immune milk (CPIM) on cellular and humoral immune functions in mice. Method Sixty ICR mice were divided into five experimental groups and a control group. The mice in experimental groups were given i.p. Ganoderma lucidum polysaccharide (GLP) immune milk,Lycium barbarum polysaccharides (LBP) immune milk and different doses (low,medium and high) CPIM,and the control group was given equivalently skimmed and sterilized goat's milk respectively for 15 d. The cellular and humoral immune functions and the feces were examined. Results Transformation ability of spleen lymphocytes:There were highly marked differences between all experimental groups and control group,between medium dose group of CPIM and GLB group,LBP group (P

Objective To investigate the clinical features and incidence of depression in patients with different lo-cations and pathological types of brain tumors. Methods Hamilton Depression Scale (HRSD) was used to assess the de-pression in 140 patients with brain tumor before and after operation. Results The preoperative mean depression rating score was 15.36 ± 6.52 and the prevalence rate of depression was 50 cases (35.7%) in 140 patients with brain tumor. The postoperative mean score of depression was 9.71 ± 5.55 and the prevalence rate of depression was 9 cases (6.4%) in 140 patients with brain tumor. The postoperative depression score and the prevalence rate was significantly decreased after op-eration (P<0.05)(χ2=36.10,P<0.05). The postoperative depression score in either benign or malignant brain tumors was significantly lower after than before operation(all P<0.05)The postoperative depression score in either the left or right or bilateral brain lesions were significantly decreased after than before operation(all P<0.05).Conclusion Pa-tients with brain tumors have different degrees of depression in perioperative. Depression may be associated with brain tu-mour pathological types and lesion sites in patients with brain tumors.
