Streptococcus bovis endocarditis associated with colonic adenocarcinoma: report of a case.

Streptococcus bovis (S. bovis) endocarditis has been increasing over recent decades, especially among the senile population. A 74-year-old man presented with intermittent fever for two months.

Cardiac metastasis of hepatocellular carcinoma mimicking pericardial effusion on radionuclide angiocardiography.

A 51-year-old man presented with exertional dyspnea for two months. He had a history of hepatocellular carcinoma that was totally resected three years earlier. Radionuclide angiocardiography disclosed a large photopenic area separating the heart from the liver, and lung blood pools mimicking a large pericardial effusion.

Inhibition of experimental carcinogenesis by painting with garlic extract.

The inhibitory effect of topical garlic extract on 7,12-dimethylbenz[a]anthracene (DMBA)-induced oral carcinogenesis in Syrian hamsters was studied to define the local anticarcinogenicity of garlic. Two other chemicals, benzo[a]pyrene (BP) and 5-nitroso-2,4,6-triaminopyrimidine (NTP), were also testing materials. All chemicals were applied topically to the cheek pouches of hamsters.

Desmoplastic amelanotic melanoma of palate: a case report with immunohistochemistry and electron microscopic studies.

A 24 year-old male with painful swelling over the right side of his palate for about two weeks was presented. An incisional biopsy was performed. In a routine hematoxylin and eosin examination by light microscopy, spindle and epithelioid cells with a bizarre appearance were discernible in the submucosal area.

The inhibitory effect of oral administration of garlic on experimental carcinogenesis in hamster buccal pouches by DMBA painting.

The inhibitory effect of oral administration of garlic on experimental carcinogenesis in buccal pouches induced by painting 9,10-dimethyl-1,2-benz(a)anthracene (DMBA) was studied on 40 golden Syrian hamsters. The animals were grouped at random into four experimental groups (oral administration of garlic, NTP, BP or mineral oil followed by DMBA painting on buccal pouches), three chemical control groups (oral administration of garlic, NTP or BP without DMBA painting) and a DMBA control group (only painted DMBA on buccal pouches). Starting from the fourth week after DMBA painting, the pouch mucosae were examined biweekly for its tumor formation and blood vessel architecture.

Hypothalamic monoaminergic mechanisms of aspirin-induced analgesia in monkeys.

Microinjection of sodium acetylsalicylate (aspirin, 0.2-0.6 mg) into the preoptic anterior hypothalamic area, but not the dorsal raphe region or the periaqueductal central gray matter, produced a dose-related analgesia in conscious monkeys.

Possible role of central serotoninergic neurons in the development of dental pain and aspirin-induced analgesia in the monkey.

The effects of aspirin or 5-hydroxytryptamine (5-HT)-related drugs on the dental pain induced by electrical stimulation of tooth pulp afferent fibers were assessed in conscious monkeys. The electrical current required for producing jaw opening is referred to as the pain threshold. Both systemic (25 to 75 mg/kg, i.

Collagenase: localization in polymorphonuclear leukocyte granules in the rabbit.

Polymorphonuclear leukocyte granules were submitted to zonal fractionation through a discontinuous sucrose gradient. Azurophilic and specific granules were enzymatically characterized by peroxidase and alkaline phosphatase activity, respectively. The enzymes formed modal distributions like those reported by others.
