13. Comparison of alendronate and sodium fluoride effects on cancellous and cortical bone in minipigs. A one-year study.
Fluoride stimulates trabecular bone formation, whereas bisphosphonates reduce bone resorption and turnover. Fracture prevention has not been convincingly demonstrated for either treatment so far. We compared the effects of 1-yr treatment of 9-mo-old minipigs with sodium fluoride (NaF, 2 mg/kg/d p.o.) or alendronate (ALN, 4 amino-1-hydroxybutylidene bisphosph

14. Transfer of the Pheromone-Inducible Plasmid pCF10 among Enterococcus faecalis Microorganisms Colonizing the Intestine of Mini-Pigs
A new animal model, the streptomycin-treated mini-pig, was developed in order to allow colonization of defined strains of Enterococcus faecalis in numbers sufficient to study plasmid transfer. Transfer of the pheromone-inducible pCF10 plasmid between streptomycin-resistant strains of E. faecalis OG1 was investigated in the model. The plasmid encodes resistan

15. Use of norfloxacin to study colonization ability of Escherichia coli in in vivo and in vitro models of the porcine gut.
The colonization resistance conveyed by the intestinal microbiota can prevent colonization of the intestinal system by new strains. In this study, this resistance was partly circumvented by use of the antimicrobial drug norfloxacin. The colonization abilities of two closely related Escherichia coli strains, which were resistant to nalidixic acid and rifampin

16. Calcium regulation and bone mass loss after total gastrectomy in pigs.
OBJECTIVE: Total gastrectomy often results in postgastrectomy bone disease with decreased bone mass and increased fracture risk. To further elucidate the mechanisms of postgastrectomy bone disease, the authors investigated calcium metabolism and bone mineral density after total gastrectomy in pigs. SUMMARY BACKGROUND DATA: Postgastrectomy bone disease can pr

17. Distraction Osteogenesis Enhances Remodeling of Remote Bones of the Skeleton: A Pilot Study
Bone injuries have a systemic influence on the remodeling of bone. This effect has not been examined concerning its extent and duration. We measured the systemic effect of distraction osteogenesis on the remodeling of bones of the axial skeleton by means of the mineral apposition rate and bone formation rate in an animal experiment. Distraction osteogenesis

18. Detection and Characterization of Porcine Endogenous Retrovirus in Porcine Plasma and Porcine Factor VIII
The pig genome contains porcine endogenous retroviruses (PERVs) capable of infecting human cells. Detection of infectious retrovirus in porcine peripheral blood mononuclear cells and endothelial cells suggested to us that pig plasma is likely to contain PERV. Both PERV env sequences and viral reverse transcriptase (RT) activity were detected in all plasma sa

19. The ultrastructure of the sensory end-organs (baroreceptors) in the atrial endocardium of young mini-pigs.
Light and electron microscopical studies on pig hearts have confirmed the presence in the right and the left atrial endocardium of distinct circumscribed, unencapsulated end-organs (baroreceptors) associated with 4-9 mum thick nerve fibres. The myelin sheath terminates before the entrance of the nerve into the end-organ. The regular presence of thin axon pro

20. Characterization and Cloning of the Genes Encoding Enterocin 1071A and Enterocin 1071B, Two Antimicrobial Peptides Produced by Enterococcus faecalis BFE 1071
The pH-neutral cell supernatant of Enterococcus faecalis BFE 1071, isolated from the feces of minipigs in Göttingen, inhibited the growth of Enterococcus spp. and a few other gram-positive bacteria. Ammonium sulfate precipitation and cation-exchange chromatography of the cell supernatant, followed by mass spectrometry analysis, yielded two bacteriocin-like
