The advantages of the use of vitamin E and selenium for the prevention and therapy of porcine stress syndrome

In a feeding trial lasting for months Halothane-positive fattening pigs were put on a diet containing different concentrations of vitamin E and selenium. After a Myostress application vitamin E and selenium were additionally injected in order to examine stress resistance (CK-test) and regenerative capacity (histological examination of Musculus longissimus dorsi) of skeletal muscle. The study revealed that neither high dietary levels of vitamin E/selenium nor a vitamin E/selenium treatment applied after stress are capable of preventing stress related myopathy nor can they influence its healing up favourably.

分泌抗鸡Ig单抗杂交瘤细胞系的建立与单抗生物学特性的鉴定

从传染性法氏囊病病毒（ＩＢＤＶ）单克隆抗体（ＭｃＡｂ）杂交瘤细胞系１Ｄ１０、１Ｇ１中得到了３株能稳定分泌抗鸡免疫球蛋白（Ｉｇ）ＭｃＡｂ的杂交瘤细胞系１Ｂ７、１Ｄ７、３Ｇ６。其抗体类和亚类均属ＩｇＧ２ｂ，腹水的ＥＬＩＳＡ效价≥１∶２５６００，琼扩效价为１∶８～１∶１６。３株ＭｃＡｂ能与鸡血清中的Ｉｇ出现沉淀反应，琼扩在２４ｈ以内出现清晰的沉淀线，而不能和鸭、鸽、鹌鹑等禽类及异种动物血清出现沉淀线。纯化的鸡ＩｇＧ、ＩｇＭ经ＳＤＳ－ＰＡＧＥ后，分别用纯化并经辣根过氧化物酶（ＨＰＲ）标记的１Ｂ７、１Ｄ７、３Ｇ６单抗酶结合物进行免疫印迹试验证明，３株单抗识别的均为ＩｇＧ、ＩｇＭ分子的轻链     

Homeopathy: an effective and risk-free alternative to conventional pharmacotherapy? Part 1: Hahnemann and his teaching]

The article considers the attractions and dangers of homeopathic therapy from the view of a pharmacologist. Homeopathic drugs may exert pharmacodynamic (but also toxic) effects at low dilutions (D0-D6), but there is no scientific proof for specific effects of higher dilutions except for substances with a high toxic potential. Most homeopathic drugs have no reasonable basis for clinical use but, in case of toxic compounds, especially those with carcinogenic or allergic potential, homeopathy may bear risks for the animal and, because of residues in food animals, also for humans. Thus, homeopathic treatment should not be used when effective conventional treatments are available, and the use of homeopathic drugs with toxic potential should be avoided.

Laboratory parameters for the control of the course of therapy of canine Cushing's syndrome]

We compared the results of the ACTH stimulation tests with measurements of alkaline phosphatase and serum cholesterol during Lysodren therapy in 23 dogs with pituitary-dependent hyperadrenocorticism. The ACTH stimulation test proved to be a very sensitive parameter, by which the extent of Lysodren under- or overdosage could be reliably estimated. On the other hand, regulation of the individual Lysodren requirement was not possible by measuring AP and serum cholesterol only. However, it is highly probable that those two parameters can be used to evaluate the general state of metabolism, and they appear to be of prognostic value when greatly elevated.     

Cystocentesis in dogs and cats]

The technique of cystocentesis in dogs and cats was studied. The indications and contraindications of this method are discussed, using illustrations.
