Sheep red cells coated with rabbit IgG antibody may be used to detect IgM rheumatoid factors either by agglutination or microscopically by the fluorescence of antihuman IgM antibody conjugate bound to rheumatoid factors on the cell surface. By substituting for red cells the plastic surface of a filter disc coated with rabbit IgG it was possible to elute the bound conjugate and measure the fluor...

The beneficial effect upon osteogenesis of impregnating allograft (homograft) bone with autologous red marrow has been reported in several publications (Burwell 1964, 1966; Matthes, Gibel, Wildner and Marx 1968; Boyne 1970; Nade 1970). This paper reports a study of the fate of sheep and calf cancellous bone grafts impregnated with autologous red marrow and implanted into rats as composite xenog...

The development of colonies in nutrient rabbit, red cells exhibited enhancing agar in vitro from mouse hemopoietic ability, as did osmotically lysed erythrocells, in the presence of a maximal dose cyte preparations from rats. The use of of colony-stimulating activity (CSA), was red cells in the culture system, in addigreatly enhanced by the addition of lion to a maximum concentration of CSA, wa...

Red corpuscles with nuclei contain heterogeneous sheep antigen when the organs of the same animal possess it. The sera in question contain not only heterogeneous hemolysins but also heterogeneous agglutinins. The hemolytic sera of rabbits immunized with hen red corpuscles are toxic to guinea pigs and kill them, the clinical picture being that of anaphylactic shock. Heterogeneous hemolysins are ...

Recent evidence from humans and rats indicates that nitrite is a vasodilator under hypoxic conditions by reacting with metal-containing proteins to produce nitric oxide (NO). We tested the hypothesis that near-physiological concentrations of nitrite would produce vasodilation in a hypoxia- and concentration-dependent manner in the hind limb of sheep. Anesthetized sheep were instrumented to meas...

In an enclosure-type study, I investigated the use of odor, auditory, and visual cues to enhance lithium-chloride (LiCl)induced prey aversion in coyotes (Canis latrans). Eight adult, male, wild-caught coyotes that killed 2 adult sheep during successive daily, 1 -hr trials were assigned to LiCland sodium-chloride (NaCl)-bait groups. The 4 LiCl-bait coyotes were sequentially presented with leg-of...

Sheep are efficient converters of unutilized poor quality grass and crop residues into meat and skin. Growth is a trait of economic importance in sheep as sheep rearing is an important livelihood for a large number of small and marginal farmers in India. Information about growth model parameters is very useful for selection studies. Growth in farm animals has been investigated for many years [1...

The sheep tick Ixodes ricinus (L.) (Acari: Ixodidae) is an ectoparasite of major economic and pathogenic importance in Scotland. Its distribution in the Scottish uplands is assumed to be governed by the abundance and distribution of its definitive hosts (deer and sheep) and climatic variables such as temperature and rainfall. As the numbers of its major host in Scotland, red deer, have increase...
