为了阐明幼虫密度对草地螟Loxostege sticticalis L.(鳞翅目:螟蛾科)细胞免疫能力的影响,本研究调查了在活体灰菜植株上1,5,10和20头/瓶(900 mL)4种密度条件下的其5龄幼虫血细胞种类、数量和组成.结果表明:草地螟幼虫血淋巴中有原血细胞、浆血细胞、颗粒血细胞、珠血细胞和类绛色血细胞等5种(类)血细胞.血细胞总数、浆血细胞、颗粒血细胞数量随幼虫密度的增加而显著递增,但原血细胞、珠血细胞和类绛色血细胞数量在幼虫密度间的差异不明显；各种血细胞所占血细胞总数的比例在4个密度中的排序相同,但10和20头/瓶密度下的浆血细胞比例显著高于l头/瓶的,其余4种血细胞的比例在不同密度之间无显著差异.可见,幼虫密度主要是通过影响草地螟幼虫浆血细胞和颗粒血细胞的数量及血细胞总数,从而影响草地螟的细胞免疫能力.

为了阐明草地螟Loxostege sticticalis大发生种群幼虫取食行为特征,在室内条件下(温度22±1℃,相对湿度70％)对不同幼虫密度[1,10,30头/瓶(650 mL)]饲养草地螟幼虫的食物利用率及消化酶活性进行了研究.结果表明:幼虫中等(或高)密度对草地螟幼虫相对中肠重量、相对取食量、粪便干重、食物利用率和近似消化率及总蛋白酶和亮氨酸氨肽酶活性影响显著.幼虫相对中肠重量以10头/瓶的幼虫密度最大,1头/瓶的幼虫密度最小.随着幼虫密度的增加,幼虫相对取食量和粪便干重增加,而虫体干重减轻,幼虫食物利用率降低.幼虫密度30头/瓶的幼虫相对取食量和粪便干重显著高于1和10头/瓶的,而30头/瓶的幼虫食物利用率显著低于1头/瓶的.幼虫近似消化率随幼虫密度的逐渐增加而显著降低.幼虫密度10头/瓶的幼虫总蛋白酶和亮氨酸氨肽酶的活性显著高于1和30头/瓶的,而淀粉酶的活性受幼虫密度影响不显著.随幼虫密度的增加,幼虫相对中肠重量与总蛋白酶和亮氨酸氨肽酶活性变化趋势较为一致,消化酶活性的变化可能与相对中肠重量大小有关.因此,幼虫密度是影响草地螟幼虫取食行为的重要因子,这些结果为阐明草地螟大发生种群与一般种群的为害特征提供了重要理论依据.

[Objective]To study the effects of different injecting methods of hepatitis B immunoglobulin to block vertical transmission of hepatitis B virus (HBVM).[Methods] 200 cases of hepatitis B markers (HBVM)-positive pregnant, 100 cases of hepatitis B virus DNA (HBV-DNA)-positive pregnant were randomly divided into A group (50 cases) and B group (50 cases); 100 cases of hepatitis B virus (HBV) carriers (HBV-DNA negative) in pregnant women were randomly divided into C groups (50 cases) and D group (50 patients) .Group A and C after 36 weeks were injected with HBIG (hepatitis B immune globulin) 200IU; group B and D were not injected HBIG.200 cases were taken venous blood samples after 36 weeks of pregnancy and childbirth for HBVM qualitative test and HBV-DNA quantification test.Newborns were divided into group A1, B1, C1, D1.Four groups were injected with HBIG 100IU 6 hours and one month after birth, and vaccinated Hepatitis B vaccine 10ug 12h, one month and 6 months after birth .Blood samples of neonatal cord and 6-month-old were taken for HBV qualitative and HBV-DNA quantification.[Results] ① There was no significant differences between group A and B for mean titer of serum HBV-DNA before and after pregnant inoculation (P﹥0.05).Compared group A, B, C, D with each other for mean titer of serum HBV-DNA before and after pregnant inoculation, there were no significant differences (P﹥0.05).② There was significant difference between group B1 and C1 regarding HBsAg-DNA positive rates (P﹤0.05), and the others had no difference between each other.③ The HBV infection rate of 6-month-old of group A1, B1, C1, D1 were 8.0%, 10.0%, 6.0% and 6.0%, Comparing the four groups with each other on the rate of mother to child transmission-blocking, there were no significant difference (P﹥0.05).[Conclusion] The HBV-DNA-positive and HBV carriers in third trimester pregnant, whether they are injected with HBIG or not, cannot affect the effect of blocking HBV vertical transmission with the combined immunodeficiency application of HBIG and HBVac to their newborn at birth.

Physical properties,tissue properties,and protective enzyme systems of five fresh tobacco leaves,and physical properties of five cured tobacco leaves were studied.The results showed that there were distinct differences in physical properties of fresh,flue-cured tobacco leaves,tissues properties,and protective enzyme systems among those five leaves.Among the five different fresh tobacco leaves,the grey and the greenish yellow leaves had poor curing characteristics,normal leaves had typical matural characteristic,organizational structure and cell alignment of odd shaped leaves was very loose,and odd shaped leaves had many cavum.Among five different cured tobacco leaves,the grey and compact leaves had poorer quality,the loose leaves had better quality,the quality of “HE AI” tobacco leaves was normal.
