Interleukin-15 is a multffunctional cytokine,which are the activating and induction factors of the T-cell,B-cell,NK-cell and lymphokine-activated killer cell (LAK).It can stimulate hematopoietic stem cell proliferation and differentiation,enhance immunity and has anti-tumor effects.IL-15 and IL-2 have similar structures and functions,but many activating effects of IL-15 are stronger than the other's.IL-15 is closely related to tumor development,and has broad application prospects in biological therapy of cancer.

ObjectiveTo investigate the protective effect of testosterone on motor neuron after sciatic nerve injury. MethodsTwelve adult C57 male mice were randomly divided into two groups: the sesame oil control group (n= 6) and the testosterone experimental group (n= 6). Unilateral sciatic nerve cutting severed as the animal model. Following operation, sesame oil or testosterone was administered for the control and experimental animals respectively via subcutaneous injection every other day for two weeks. The number and soma area of the anterior horn motor neurons in the lumbosacral cord of the sciatic nerve injury side were then measured on Nissl stained sections. Results In the testosterone group the motor neurons appeared healthier than that in the sesame control group. The neurons were plumper and showed more processes. Their number and average soma size were significantly larger than that in the sesame control (P<0.01). Conclusion The findings demonstrate that testosterone has a significant protective effect on sciatic nerve motor neurons after nerve injury.

Objective To study the changes of leptin and insulin-like growth factor-Ⅰ (IGF-Ⅰ) in adoles-cents with anorexia nervosa(AN) before and after three months of therapy. Methods The plasma levels of leptin and IGF-Ⅰ were measured in 11 adolescents with AN before and after three months of therapy and 11 normal ado-lescents of the same age,and their height,weight were examined and their body mass index(BMI) was calculated,and the results were compared before and after therapy, and were compared with those from age-matched normal adolescents respectively. Results (1)The plasma levels of leptin and IGF-Ⅰ , as well as the BMI in the AN patients after three months of therapy were significantly higher, than those before the therapy, and both were significantlylower than those in the controls. (2)Significant correlations between the plasma leptin levels and IGF-Ⅰ and BMI were detected in the AN patients both before and after the therapy, as well as in the controls. (3)Significant correla-tions between the plasma leptin levels and IGF-Ⅰ were detected in the AN patients both before and after the thera-py, as well as in the controls. Conclusion The plasma levels of leptin and IGF-Ⅰ resulted in significant changes, and these changes were consistent with body fat content in adolescents with AN.

Objective To compare the influence of aging on apoptosis and the expression of apoptosis-related protein in adult and aged male Wistar rat hearts after acute coronary artery occlusion. Methods The acute myocardial infarction rat model was established by left anterior descending(LAD)occlusion.A total of 115 adult and aged rats,aged 6-24 months,were included in the study.The rats were divided into 4 groups:aged model group,aged control group,adult model group and adult control group.Animals were killed 1,3,5 hours,1 and 7 days after coronary occlusion.Hemodynamic parameters[heart rate(HR),left ventricular systolic pressure(LUSP),left ventricular end-diastolic pressure(LVEDP),±dp/dtmax)]were obtained from each group at every time points.The apoptosis and necrosis of myocardium were detected with TUNEL way and TTC stain.The expressions of Bcl-2 and Bax were analyzed with immumohistochemical stain. Results DNA fragmentation occured 1 hour after coronary occlusion and apparently peaked earlier in the aged than in the adult rat hearts.At 3 hour,the apoptotic index of aged model group was obviousily higher than that in adult model group[(51.90±23.15)%us.(18.67±17.15)%,P<0.01].The basal levels of Bcl-2 and Bax were higher in the aged than in the adult rat hearts.The expression of Bcl-2 in aged model group and adult model group were 2.7±0.9 and 1.8±0.8,P<0.05.The expression of Bax in aged model group and adult model group were 6.2±2.9 and 4.2±1.5,P<0.05. Conclusions The ability of aged rats to resist ischemia is poor,aging may alter the expressions of Bcl-2 and/or Bax,increase cardiomyocyte apoptosis,thereby,enhance the myocardial dysfunction during acute myocardial infarction.
