Sunscreen Recovery Studies in the Mexican Hairless Dog

The skin injury induced by high energy dose of ultraviolet in hairless descendants of Mexican hairless dogs.

Histopathological changes in the dorsal skin of hairless descendants of Mexican hairless dogs (MHDs) exposed to artificial irradiation with high energy dose (180 kJ/m2) of ultraviolet (UV) rays (UVA + B) were investigated. Macroscopically, erythema and edema were observed in the irradiated skin at 1 day after irradiation (DAI), and blister formation occurred except one dog at 2 DAI. Erythema al...

Effect of a static magnetic field on bone healing in the dog: radiographic and histopathological studies

Although the promotional effects on bone healing of pulsed electromagnetic fields (PEMF) have beenwell demonstrated, the effects of static magnetic fields (SMF) remained unclear. In this study, effects of acustom-made magnetic wrap on radiographic and histopathological aspects of bone healing using a canineunstable osteotomy gap model were investigated. After an osteotomy of the midshaft radius...

Local Recovery in Experimental Pneumococcus Lobar Pneumonia in the Dog

An investigation has been made of the process of local recovery occurring in the pulmonary lesions of dogs with experimental pneumococcus lobar pneumonia. Six animals showing simultaneous healing and spread of the pathological process in different parts of the lungs were sacrificed during the active stage of the disease for bacteriological and histological study. It was found that with few exce...

Granulocytic recovery in the polycythemic dog treated with endotoxin postirradiation.

This experiment was designed to test the hypothesis that, in hypertransfused dogs with suppressed erythropoiesis, endotoxin-induced increased myelopoietic stimulation 24 hours after irradiation would enhance leukocytic recovery. The treatment combination of transfusion polycythemia and endotoxin was compared to a control group receiving no therapy or to the results obtained from groups of dogs ...
