When comparing, in a murine model, the kind of graft-versus-host (GVH) disease (GVHD) induced by the donor strain DBA/2 on the one hand and several H-2-congenic resistant B10 donor strains on the other, we found that strain DBA/2 was a universal nonkilling GVH donor for H-2-incompatible nonirradiated F1 hybrid recipients. In this respect, DBA/2 T cells differed from those of the H-2-identical d...

Various immune response pathways are altered during early, predegenerative stages of glaucoma; however, whether the early immune responses occur secondarily to or independently of neuronal dysfunction is unclear. To investigate this relationship, we used the Wlds allele, which protects from axon dysfunction. We demonstrate that DBA/2J.Wlds mice develop high intraocular pressure (IOP) but are pr...

There is growing agreement that genetic factors play an important role in the risk to develop heroin addiction, and comparisons of heroin addiction vulnerability in inbred strains of mice could provide useful information on the question of individual vulnerability to heroin addiction. This study examined the rewarding and locomotor-stimulating effects of heroin in male C57BL/6J and DBA/2J mice....

People infected with Trypanosoma cruzi remain so for life, yet only 30-40% of these individuals develop characteristic chagasic cardiomyopathies. Similarly, when infected with the Brazilian strain of T. cruzi, DBA/2 mice develop severe cardiac damage while B10.D2 mice do not. To better understand the immunological parameters that may be involved in the disease process, we have used this murine ...

Dibenz[a,h]anthracene (DB[a,h]A) and its microsomal metabolites, trans-3,4-dihydro-3,4-dihydroxydibenz[a,h]anthracene (DBA-3,4-diol), trans,trans-3,4:8,9-tetrahydro-3,4:8,9-tetrahydroxydibenz[a,h]anth racene, trans,trans-3,4:10,11-tetrahydro-3,4:10,11-tetrahydroxydibenz[a,h] - anthracene (DBA-3,4,10,11-bis-diol) and trans,trans-3,4:12,13-tetrahydro-3,4:12,13- tetrahydroxydibenz[a,h]anthracene w...

A 7 year old girl is described with congenital hypoplastic anaemia (Diamond-Blackfan anaemia, DBA) and an apparently balanced reciprocal translocation, 46,XX,t(X;19)(p21;q13). The girl has associated features including short stature, unilateral kidney hypoplasia, and a branchial cyst. Fluorescent in situ hybridisation (FISH) studies with 19q specific cosmids showed that the chromosome 19 breakp...

Implanted tumors and methylcholanthrene Carcinogenesis increase the turnover of phosphorus in the total nucleic acids of histologically normal DBA/1J mouse skin. As the implanted tumors progress for 6 days, the turnover rate of nucleic acid phosphorus in the histologically normal skin increases to 4 times that of control skin from normal DBA/1J mice. At this same time, 68% of the histologically...

This study was designed to measure the sound output of four commonly used brands of forced-air dryers used by dog groomers in the United States. Many dog groomers have questions about the effect of this exposure on their hearing, as well as on the hearing of the dogs that are being groomed. Readings taken from each dryer at 1 meter (the likely distance of the dryer from the groomer and the dog)...

AIMS--To evaluate the immunoreactivities of neoplastic and non-neoplastic monocytoid B cells (MBC) and compare them with hairy cell leukemia (HCL) and mantle cell lymphoma (MCL). METHODS--An immunohistochemical study of paraffin wax embedded sections was done on surgically resected specimens of spleens with MBC clusters from patients with gastric cancer (14 cases), tonsils (five cases), and lym...
