Our experimental study was conducted on twenty seven healthy male albino mice, whose ages ranged from 5 to 6 weeks and weight range was 23-26gm with standard deviation (Std) equals to 1.83. The mice were randomly divided into three groups (9 mice each). The first group of mice was served as a control and not irradiated with laser, while both second and third groups of mice were anaesthetized and irradiated by using diode laser (λ = 890nm)  which was focused on the upper right quadrant of the abdomen where the liver is located. It was concluded from our study that although laser exposed to both second and third groups of mice for 5 and10 minutes once daily respectively during the entire period of experimentation (6 days), the laser did not affected their hepatic tissue structure. https://biomedpharmajournal.org/vol12no2/histological-investigation-of-the-hepatic-tissue-in-mice-induced-by-soft-laser-with-different-doses/ Histological Alterations Laser Treatment Liver Mice
