Using a bee resin mouthwash for a week doesn't change how well blood flows to the forearm during a temporary blood flow restriction test.
Quantitative
Using a common antibacterial mouthwash for a week can increase sugar and lactic acid levels in saliva, which might make it easier for tooth decay to develop.
Using a common antibacterial mouthwash for a week can lower ammonia levels in saliva, which might make it harder for the mouth to maintain a healthy environment.
Using a bee resin mouthwash for a week doesn't change the levels of important substances in saliva like pH, nitrite, or sugar levels.
Using a common antibacterial mouthwash for a week can make saliva more acidic and less able to neutralize acids, which might make tooth decay more likely.
Using a common antibacterial mouthwash for a week can increase the number of bacteria that cause gum disease.
Using a bee resin mouthwash for a week doesn't change the types or numbers of bacteria that produce nitrite in the mouth.
Using a common antibacterial mouthwash for a week can lower nitrite levels in saliva, which might make it easier for tooth decay to develop.
Using a common antibacterial mouthwash can increase the number of certain bacteria that produce nitrite, but actually makes those bacteria less effective at producing nitrite.
Using a bee resin mouthwash for a week can slightly lower systolic blood pressure (by about 2 points), but it's unclear if this small change actually improves health outcomes.
Using a special mouthwash made from bee resin for a week can raise nitrate levels in the blood, which might help lower blood pressure.
In rats prone to high blood pressure, the types and amounts of bacteria on the skin are affected by the rat's genetic makeup, but this effect is different for male and female rats.
Correlational
In rats prone to high blood pressure, the types and amounts of bacteria in the mouth are affected by the rat's genetic makeup.
The amount of sodium stored in the skin is linked to blood pressure levels in both humans and animals.
Cyanobacteria on the skin might help regulate sodium levels and blood pressure through special transporters that move sodium and chloride.
Mechanistic
Bacteria in the mouth that convert nitrate to nitric oxide (like Actinobacteria) might help lower blood pressure by relaxing blood vessels.
In rats with different genetic modifications that affect blood pressure, the connection between gut bacteria and blood pressure isn't consistent - sometimes more of certain bacteria is linked to lower blood pressure, sometimes not.
In rats with different genetic modifications that affect blood pressure, the types and amounts of bacteria in the gut differ between these strains.
Descriptive
In rats with different genetic modifications that affect blood pressure, the types and amounts of bacteria on the skin differ between these strains.
In rats with different genetic modifications that affect blood pressure, the types and amounts of bacteria in the mouth differ between these strains.
In female rats, a specific part of the genome (RNO5) is linked to the amount of Cyanobacteria bacteria on the skin, and this is connected to blood pressure levels.
In rats, a specific part of the genome (RNO10) controls the amount of Actinobacteria bacteria in the mouth, and this is linked to blood pressure levels.
In rats, the bacteria in the gut are different from those in the mouth and on the skin, with Bacteroidetes and Firmicutes being the most common types in the gut.
In rats, the bacteria on the skin are different from those in the mouth and gut, with Cyanobacteria being the most common type on the skin.
