UNLABELLED Periodontal inflammation with alveolar bone resorption is a hallmark of periodontitis. We hypothesized that extracorporeal shock wave therapy (ESWT) could promote the regeneration of alveolar bone following Porphyromonas gingivalis-induced periodontitis in rats. Rats were infected with P. gingivalis for 10 wks, which caused alveolar bone(More)
BACKGROUND Hidradenomas are adnexal tumors that may grow to be very large and frequently recur after excision. Malignant transformation and metastatic spread can occur and histologic distinction of benign from malignant hidradenomas can be very difficult. Some tumors with bland histology have demonstrated aggressive behavior. OBJECTIVE To decide the(More)
We have recently demonstrated that extracorporeal shock-wave therapy (ESWT) is effective in promoting the healing of dermal wounds and in regenerating alveolar bone lost through periodontal disease. The objective of the present study was to determine any antibacterial effect of ESWT on oral bacteria. Monoculture suspensions of 6 bacterial species were(More)
We describe a patient with malignant melanoma that resembled a Merkel cell carcinoma both clinically and histologically. Immunohistochemical studies showed focally positive staining with S-100 protein and strongly positive staining with HMB-45. Ultrastructural study confirmed the diagnosis by demonstrating premelanosomes and melanosomes. Although the tumor(More)
782 Erythropoiesis was evaluated by plasma Fe #{176}disappearance ( T #{189}Fe59 ) and per cent incorporation of Fe59 into erythrocytes ( per cent Fe5#{176}RBC ) of the dog within 4 days without dialysis. Average results are given. Sham-operated and iron-overloaded animals were controls ( N = 10, T#{189}Fe59 92, 82 minutes; per cent Fe59 RBC 90, 71 per(More)
