Digitalis Inactivation in Vitro Due to Rumen Microbes from Sheep

Permeability to thiamin of the sheep rumen wall in vitro.

In vitro experiments were conducted to study the permeabil i ty to thiamin of sheep rumen wall in either direction. Isolated discs of rumen wall mucosa were used in incubation experiments over 3 hr, controlled by measurements of transmural potentials. In some experiments 14 C-labeled thiamin was used. At thiamin concentrations in the mucosal fluid ranging from .1 to 1.6/ag/ml no changes of the ...

Abortion due to Brucella abortus in Sheep in Iran

[Bidirectional ventricular tachycardia due to digitalis poisoning].

Digitalis intoxication is a frequent outcome of chronic treatment with digitalis glycosides but uncommon following accidental intake or self-poisoning.1 Ventricular arrhythmias are an expression of this complication and can usually be controlled thru conventional means including suspension of the drug. However, in the presence of potentially lethal arrhythmias and kidney failure difficult decis...

Effect of rumen bacteria from sheep adapted to a tanninferous diet on in vitro fermentation parameters of pistachio hulls using bovine inoculum

Sheep adapted to consume tannins rich feeds such as oak leaf (OL) appear to develop defensive mechanisms by their ruminal bacteria against these polyphenols. The capabilities of ruminal isolated tannins resistant bacteria from these animals to ferment a tanniniferous feed (i.e., pistachio hulls, (PH) which were incubated with rumen fluid from Holstein dairy cows was assessed. Six g positive coc...
