Bioavailability of two ibuprofen oral paste formulations in fed or nonfed ponies.

The bioavailability and pharmacokinetics of ibuprofen, a nonsteroidal antiinflammatory drug, was studied in healthy Shetland ponies. Ibuprofen was administered IV, as a suspension, and as a solid solution oral paste to ponies from which food was withheld. The suspension paste was also administered to ponies that received hay and water ad libitum. Both formulations had an absolute bioavailability of about 80%. Bioavailability was not influenced by feeding.

A hypervariable pig DNA fragment.

A new hypervariable tandem repeat was isolated from the pig genome and characterized by DNA sequence. The use of this DNA fragment as a probe in order to follow allelic segregation and DNA fingerprinting in pigs, horses and rabbits is documented.

Swine lymphocyte alloantigens (SLA) class I serology and genetics in Belgian Landrace and Pietrain breeds.

Eighty anti-SLA class I reagents were prepared resulting from skin graft and subcutaneous immunizations in 320 fattening pigs of the Belgian Landrace and Pietrain breeds. By means of these alloantisera seven internationally and five locally established specificities were recognized. Three of the locally assigned specificities were new: BM 36, BM 37 and BM 38. They were serologically and genetically defined. The typing battery was completed with French and Danish reagents, and correlation coefficients were calculated for the main alloantisera recognizing SLA class I alloantigens observed in the Belgian breeds. The SLA haplotype frequencies were estimated in 372 Belgian Landrace and 369 Pietrain pigs. The SLA haplotype distribution differs significantly between both breeds and the genetic distance (0.54) at the SLA system is quite high.

A third variant of glucose phosphate isomerase in pigs.

A new variant of glucose phosphate isomerase (GPI), also known as phosphohexose isomerase (PHI), was detected in a primitive pig population.

Evolutionary conservation of the linkage between the structural loci for serum albumin and vitamin D binding protein (Gc) in cattle.

Evidence is presented for close genetic linkage between the structural loci for serum albumin and the vitamin D binding protein (Gc) in Belgian Blue and White cattle. Five recombinants were observed in a total of 342 informative offspring. The recombination frequency between the two loci was estimated as 1.5% +/- 0.9. The observed distribution of the haplotypes deviated from the expected one in the population, probably due to selection and significant linkage disequilibrium.

The position of the epistatic S locus in the halothane linkage group in pigs.

The linkage of the Phi, Pgd, Po2, S, H and halothane sensitivity loci was followed in a Belgian Landrace family, heterozygous for these systems over 6 generations. Recombination next to the S locus occurred mainly in pigs belonging to this particular family. From this investigation the position of the S locus is proved to be outwith the Phi-Pgd region, next to Phi. Therefore the gene sequence S - Phi - Hal - H - Po2 - Pgd is proposed. Higher recombination rates were observed in the female parental line of the multiheterozygous family when compared to the male parental line. Additional data from animals, unrelated to this strain, confirm the evidence of close linkage of the S system to the nearest marker loci.
