针刺不同年龄大鼠大脑皮质后,于不同时间点观察神经毡及少突胶质细胞的反应。光镜与电镜下均发现,三个年龄组在针刺后早期都有神经毡的水肿,晚期逐渐恢复,但水肿的出现和消退均以幼年大鼠最早、最显著,同时伴有明显的成髓现象,少... 针刺不同年龄大鼠大脑皮质后,于不同时间点观察神经毡及少突胶质细胞的反应。光镜与电镜下均发现,三个年龄组在针刺后早期都有神经毡的水肿,晚期逐渐恢复,但水肿的出现和消退均以幼年大鼠最早、最显著,同时伴有明显的成髓现象,少突胶质细胞肥大、核仁增大、细胞器和游离核糖体增多等。此外,变性区内仍保持结构正常的突触多见于成年及老年大鼠。上述结果表明,幼年大鼠神经组织对针刺损伤反应较敏感,其恢复速度却较快,而较老动物的胞突间连接比幼年者稳定。 展开更多

In order to ensure the existence of the gender and age differences of middle school students' shame, 1258 Shanghai middle school students are surveyed with the help of the Middle school students' shame measurement scale with the combination of delaminating and random sampling. The results of questionnaire show that there are significant gender differences in middle school students' shame and the average scores of male students' shame are higher than those of female students. Besides, there does exist significant age differences in middle school students' shame, but it is not simple linear relationship between the feeling of shame and ages. The feeling of shame reaches maximum at the age of 14 and intervention should be given at this age, which young students feel sensitive most. It is suggested that collective remission of the shame should be offered to middle school students with the methods such as physical exercises, persuasion etc. 展开更多

Several biometric measures were taken from 48 adult (mean age 2.78 ±1.71 years) Basset Hound dogs (24 males and 24 females) belonging to four different farms. For each animal, the following biometrical measurements were considered: withers height, chest height, chest depth, trunk length, rump length, ischium width of the rump, ear and nose length, chest and cannon circumference. Results showed that sexual dimorphism was not present; however two morphological groups of Basset Hound with some differences were found. The first group consisted of animals with high and broad chest, while the second one was more compact, with more pronounced nose and ears. Considering breed health, it would be interesting to select the subjects of the first group since showing an anatomical less susceptible to some conformational disorders typical of the breed. On the contrary, focusing our interest on the breed hunting attitude, the second group would have some characteristics more suitable for this purpose. 展开更多

We studied the responsiveness of the Sichuan snub-nosed monkey Rhinopithecus roxellana, an arboreal Old World monkey, to the presence of novel stimuli associated with familiar food. We also determined differences in responses by age and sex. Results showed that monkeys exhibited neophilia and neophobia simultaneously when facing novel stimuli. Age affected the response to novel stimuli significantly, with immature individuals responding to novel stimuli most frequently and infants least frequently. No significant differences were observed for sex, although females were more responsive to the novel object than were males. Our results support the "readiness to eat" hypothesis that the presence of a novel object can increase latencies to consume familiar food . 展开更多
