网络"恶搞"电影作品的法律问题研究

对电影作品的网络"恶搞"是我国网络产业发展的新产物,在形式和内容上都有其显著特点。网络"恶搞"能够迅速流行有深刻的文化和技术背景。从性质上说,网络"恶搞"属于新型文艺评论,也具备构成改编作品的条件。网络"恶搞"在网络的传播可能对电影作品的著作权、相关主体的名誉权和肖像权构成侵犯,尽管如此,我们应当在保护公民言论自由的基础上寻求对其进行规制。     

The generalized Shwartzman reaction in association with E. coli enterotoxemia in a pig.

A pig at the age of approx. 10 weeks died after four days of illness. Distinct necrotic changes were found both in the skin and the cortex of the kidneys. The histological examination revealed fibrinoid thrombi in skin vessels. In the kidneys similar thrombi were observed in capillaries of the glomeruli and in their afferent arterioles and in the interlobular arteries. In these vessels there were also a fibrinoid mural necrosis. These changes were in accordance with those expected to occur in the generalized Shwartzman reaction (GSR). The diagnosis of Escherichia coli enterotoxemia was based on the pathomorphological changes in the alimentary tract. The E. coli enterotoxemia was considered the cause of the GSR-changes.     

The Applicability of Agar-Diffusion Test in Measuring Deoxyribonucleases in Pig Intestinal Content

The suitability of an agar-diffusion test (ADT) using toluidine blue deoxyribonucleic acid agar (TDA) for measuring DNase activity in pig intestinal contents was investigated. The ADT was compared with a spectrophotometrical method. Distinct metachromatic zones around wells in the DNA-containing agar, into which the intestinal content was applied, indicated DNase activity. The DNase activity was determined semiquantitatively by making serial twofold dilutions of the intestinal content. The spectrophotometrical method was optimal at pH 7.2. The ADT proved to be most sensitive at pH 5.6. The ability of the 2 methods employed to measure low concentrations of DNases was equal. However, the ADT was considered more suitable than the spectrophotometrical method because ADT measured reduced amounts of enzyme. DNase activity was demonstrated throughout the small intestine and in the large intestine. By the zymogram technique, at least 3 different DNases could be demonstrated in the lower parts of the small intestine, 1 of which could be of extrapancreatic origin.     

地方猪种对纤维饲料利用的研究——Ⅱ.消化道形态与大肠内容物重量的变化

以三元杂种猪为对照,研究了东北民猪在3种NDF水平(0、10、20％)下消化道形态及后肠内容物鲜重的变化。试验从活重30千克开始,80千克结束时,每组在最后一次给食后的2、4、8、12或16小时随机屠宰2头。电击晕死后立即开膛取出内脏,分为胃、小肠、盲肠和结肠4段进行测量。结果表明猪对饲粮纤维含量的增加从胃肠道形态上发生明显的适应性变化,消化道长度、鲜重增加,尤其结肠长度增加明显,胃、小肠和结肠的鲜重显著地高于基础饲粮组。民猪胃重和结肠鲜重及长度的增加比对照杂种猪明显,消化道总鲜重及其占空体重的比例显著地高于对照杂种猪。随NDF水平的提高,大肠内容物鲜重明显增加,其中民猪更为突出,后肠是吸收水分的主要场所。     

Development of a leukocytopenic baby guinea pig model with azathioprine and cyclophosphamide

Immunosuppressive agents were given to baby guinea pigs to develop a leukocytopenic baby guinea pig model. Azathioprine in different doses, and cyclophosamide and methylprednisolone combinations did not result in predictable leukocytopenia without significant mortality. A combination of azathioprine 20mg and cyclophosphamide 20mg administered once daily for 5 days to 42 baby guinea pigs resulted in a mean white blood cell count of 2531/mm³ ±1198 (a reduction of 3931 ± 1413 from pretreatment values). The mean counts for polymorphonuclear leukocytes and lymphocytes on day 6 were 398/mm³ and 2035/mm³, respectively. Only 7% mortality was seen in these animals. This model can be utilized to study a variety of bacterial and viral infections in “immunocompromised hosts”.     

畜牧生产中营养物质转化规律及其影响因素

本文以生长猪、鸡为对象,着重探讨了品种间对饲料能量与球白质在消化、代谢、合成过程中的效率异同;研究了某些微量元素及其有关酶对能量、蛋白质及其它物质利用的影响。     

肥育猪肌纤维组织学特性的研究

试验用不同品种和杂种共30头肥育猪做了复因子试验,观察品种、屠宰体重和解剖学部位对肌纤维组织学特性的影响。结果表明,在肌纤维直径上存在品种X部位互作。一般而言,限肌肌纤维直径小于股二头肌,但高度培育的瘦肉型猪例外。屠宰体重间在肌纤维直径和密度上无显著差异,但屠宰体重×品种互作显著。试验的各品种间在肌纤维直径和密度上存在显著差异,以东北民猪肌纤维直径最小,肌纤维密度最大,此乃迄今为止所见国内外各品种猪最具特色的性状,可以认为这是东北民猪独特的优良肉质性状。     

Hematological and blood chemical data of pigs fed various amounts of mink manure

The effect of feeding mink manure to pigs and the utilization of its protein and mineral content was studied by blood analyses. Individual variation was large, and the differences between groups were small. Growth of the animals had a significant effect on the levels of several blood components. Judging from the blood analyses, mink manure feeding did not have any harmful effects on the health of the pigs, and the differences to normal feeding were small.     

大约克母猪排卵规律的研究

通过对大约克母猪在发情不同时间分批屠宰测定表明，大约克母猪排卵时间是在发情开始后４８小时左右至７２小时之前这一范围。并采用杜洛克和大约克公猪分别在母猪发情的不同阶段先后配种，从所产仔猪的遗传特征鉴别结果判断，排卵大多集中在发情３６小时后至６０小时左右范围内，与屠宰测定基本一致。据上试验结果，确定掌握适配期为母猪发情开始后３６－４８小时期间第一次配种，间隔１２－２４小时内复配一次。经两年配种实践取得良好效果，情期受胎率分别达到９１．２７％（２０９／２２９）和９３．３６％（２６７／８６）。     

复方噻胺酮对小型猪血清中多种元素的影响

试验采用动物给药前后自身对照的方法,观察了我国新研制的兽用复合全麻药——复方噻胺酮对10头小型猪血清中的常量元素(K,Na,Ca,Mg)和微量元素(Cu,Fe,Zn)含量的影响.结果表明,小型猪肌肉注射临床麻醉剂量(15mg/kg)的复方噻胺酮后,血清中 Na,K,Cu,Fe 可在一定时间内呈显著升高(P<0.05),Ca 显著下降(P<0.05);Mg 和 Zn 未发生显著变化.但上述诸元素的变化均未超出正常范围。尽管如此,若对已患上述诸元素缺乏或过高的动物进行麻醉时,或是需在麻醉状态下进行有关元素方面的研究时,对这种影响也应给予足够重视.
