Adjuvant effects of oral microorganisms on the immunological responses.

Effects of Hangeshashinto on Growth of Oral Microorganisms

Oral mucositis (OM) in cancer patients induced by chemotherapy or radiotherapy has a significant impact on quality of life, and causes considerable morbidity. Oral microorganisms are likely to intensify the inflammatory process and aggravate the formation of ulcers. Hangeshashinto (HST), a Japanese kampo medicine, has been reported to be effective when used as a gargle for the treatment of OM. ...

Effects of C60 Fullerene and its Derivatives on Selected Microorganisms

The contribution deals with preparation of C60 fullerene derivatives (oxo derivative, bromo derivative, hydrolyzed bromo derivative, bromo-ch loro derivative), their identification and pilot testing of their biological effects on unicellu lar organisms. The contribution describes effects of C60 fullerene derivatives, both on prokaryotic organisms (bacteria, cyanobacteria) and eukaryotic organis...

Effects of oral care on development of oral mucositis and microorganisms in patients with esophageal cancer.

We evaluated the effects of special oral care using a toothbrush with combined irrigation and suctioning functions, along with povidone-iodine to treat oral bacteria and mucositis, in esophageal cancer patients undergoing chemoradiotherapy. In the special care group, oral hygiene was performed 3 days a week after dinner. Bacteria in saliva and plague samples were measured at various sampling po...

Nicotine, its metabolism and an overview of its biological effects.

Nicotine is a naturally occurring alkaloid found in many plants. The principal sources of nicotine exposure is through the use of tobacco, nicotine containing gum and nicotine replacement therapies. Nicotine is an amine composed of pyridine and pyrrolidine rings. It has been shown that nicotine crosses biological membranes and the blood brain barrier easily. The absorbed nicotine is extensively...
