原本没有养犬的意思,常常又受养犬爱犬的美文所感染,被文章所述及的人犬深情所感动。每每此时,我都沉溺于文中主人翁的情感之中,与他们一起悲喜,乐他们之所乐,忧他们之所忧。看到犬英勇救主,奋不顾身时,常常感叹人间奇迹,感慨人犬之深情,自然之造化;看到描写犬讨好主人的媚态(天生的阿谀奉承,讨人喜欢的小精灵),常常禁不住哑然失笑,内心平生许多快乐和爱; 相似文献

These studies report on the production of African swine fever antiserum for use in serological tests. The first attempt to obtain antiserum was made by inoculating ASF virus - infected pig blood into the lactiferous sinus of lactating bovines. This failed to result in the development of detectable antibody, but resulted in propagation of the virus over a 14 to 21 day period. In the second attempt use was made of a tissue culture - attenuated virus to produce resistance in normal pigs. Clinical response to inoculation with the attenuated virus was limited to a one day increase of temperature. These pigs were subsequently orally exposed to virulent ASF virus and later challenged by intramuscular injection. The sera were subjected to testing by the modified direct complement-fixation test and the agar gel double-diffusion technique in order to follow the development of antibodies. Some sera were also conjugated with fluorescein isothiocyanate and used for the detection of viral antigen by the fluorescent antibody technique. It was found that inoculation with the attenuated virus brought about the development of low antibody levels in the pigs. This antibody level did not increase following oral exposure. One pig following intramuscular challenge underwent a series of ascending temperature peaks, coinciding with increased complement-fixing titres. 相似文献

Hypoadrenocorticism (Addison’s disease) has been referred to as “the great pretender,” due to its ability to mimic other common diseases in the dog and thereby represent a diagnostic challenge. Naturally occurring hypoadrenocorticism is an uncommon canine disease. Young, female dogs are overrepresented. Hypoadrenocorticism typically results from immune-mediated destruction of all adrenocortical layers, resulting in deficiencies of min-eralocorticoids (aldosterone) and glucocorticoids (cortisol). A small number of dogs suffer from glucocorticoid deficiency only. Dogs suffering from hypoadrenocorticism may present in a variety of conditions, from a mildly ill dog to a shocky and recumbent dog. This review discusses etiology, pathophysiology, history, physical examination findings, and diagnostic findings in the Addisonian patient. A follow-up article (Part II) will discuss the definitive diagnosis and management strategies for these patients. 相似文献

我第一次接触犬是5岁那年。那是60年代末的一个冬天,我随奶奶去兴城农村的姑姑家过冬。姑姑家住在海边的一个小渔村,虽说地理位置不错,但在极左的年代,不准搞副业,村里人的日子十分清苦。我们刚到那天,姑姑做了几个带肉的菜,以后的饭菜便是窝头、稀粥和咸菜了,但对于一个小孩来 相似文献
