The fluorinated quinolones are potent antibacterial compounds active against both gram-negative and gram-positive bacteria (1, 3-5, 11-13). Some are also active against mycobacteria in general (3, 9, 10, 13) and Mycobacterium tuberculosis in particular (1; unpublished observations). In view of the limited number of drugs active against Mycobacterium leprae, it was of interest to test some of th...

Mycobacterium marinum strains 1218 and 1219 were inoculated into the hind footpads of T-cell-depleted specific pathogen-free C57B1/6 mice, and the growth and survival of the organisms at the site of injection, the draining popliteal lymph node, and the spleen and lung were quantitated for up to 70 days. T-cell depletion largely ablated the normal cell-mediated antituberculous response to the M....

We have examined the distribution of radiolabeled liposomes in tumor-bearing mice after i.v. injection. Two mouse tumors (B16 melanoma, J6456 lymphoma) and a human tumor (LS174T colon carcinoma) inoculated i.m., s.c., or in the hind footpad were used in these studies. When various liposome compositions with a mean vesicle diameter of approximately 100 nm were compared using a radiolabel of gall...

The mutilated-foot rat (mf rat) is an autosomal recessive mutant with characteristic digit deformities in adult animals, and this phenotype mimics many aspects of human sensory neuropathy. The genetics of mf rats was recently elucidated. To understand whether the genotype is responsible for cutaneous denervation before clinically overt mutilation in adult mf rats, we investigated skin innervati...

Leishmania major (L. major) parasites are intracellular parasites belong to the Trypanosomatidae family and are the causative agent of cutaneous leishmaniasis. This disease affects approximately 1.5 million per year worldwide and there is currently no prophylactic vaccine available. L. major is transmitted by the bite of an infected sandfly and has been considered for decades now as a mouse mod...

The golden eagle is one of the world's largest living birds. Footpad dermatitis, also known as plantar pododermatitis or bumblefoot, is a condition characterized by lesions due to contact with unhealthy "perching" conditions, such as plastic perches, sharp-cornered perches on the ventral footpad of birds. A young female golden eagle (Aquila chrysaetos) in Fars province of Iran was presented to ...

based on experiments showing immunomodulatory effects of garlic (allium sativum l.), we sought to see whether allium hirtifolim boiss., belonging to the same genus of garlic, has any effect on immune responses. hydroalcoholic extract and polyphenolic fraction of a. hirtifolium bulbs were prepared. allicin (diallyl thiosulfinate), a biologically active component, was identified in plant bulbs by...
