The influence of handheld mobile phones on human parotid gland secretion.

掲載誌: Oral Dis 2010; 16 (2): 146-150

この論文は、50人の健常ボランティア(どちらか優勢な頭側で携帯電話を使用している人)の両側の耳下腺から同時に採取した唾液を分析した。唾液分泌速度は、携帯電話の使用側の方が反対側より有意に高く、唾液中のタンパク質濃度は使用側の方が低かったことを報告している。

研究目的(著者による)

To compare the parotid gland salivary secretion rate and protein concentration between dominant and less dominant sides of healthy subjects who use mobile phones.

詳細情報

The study cohort comprised 50 healthy volunteers (25 men, 25 women) with a mean of mobile phone use of seven years. Mobile phone use was assessed by questionnaire (more than half of the subjects used the mobile phone at least five times a day and only 2 % used the phone twice a day). A total of 40 participants (80%) used the right ear more frequently.
For collection of saliva samples the parotid glands were stimulated with citric acid.

研究の主なアウトカム(著者による)

In subjects whose dominant side was the right, the overall mean parotid gland flow rate was significantly higher than the rate from the left parotid gland. In subjects whose dominant side was left, the overall parotid flow rate was almost identical to that of the right parotid gland. Overall, a 2.54-fold increase in salivary secretion rate was found between the dominant and non-dominant sides.
Lower total protein concentration was found in the dominant compared with the non-dominant mobile phone side among the right dominant cell phone users. However, no significant differences were found between the protein concentrations of the two parotid glands in subjects whose dominant side was left.
The authors conclude that parotid glands adjacent to the handheld mobile phone respond by elevated salivary rates and decreased protein secretion reflecting the continuous insult to the glands.
