introduction: this paper presents the results of a study on the effects of two differentdoses of low-power laser irradiation on healing of deep second degree burns. material and methods: 60 rats were randomly allocated to one of four groups. adeep second-degree burn was inflicted in each rat. in the control group (cg) burns remained untreated; in groups lg1 and lg2 the burns were irradiated wit...

Background: Wound healing is one of the main problems faced by medical scientists. Nowadays, herbal compounds are used to accelerate the repairing process. Coumarin is a plant compound with anti-inflammatory and anti-oxidant effects. In the present study, the benefits of using coumarin in accelerating wound healing were investigated in mice.Methods: Sixty...

We report observations suggesting that the transcription elongation factor NusA promotes a previously unrecognized class of transcription-coupled repair (TCR) in addition to its previously proposed role in recruiting translesion synthesis (TLS) DNA polymerases to gaps encountered during transcription. Earlier, we reported that NusA physically and genetically interacts with the TLS DNA polymeras...

The purpose of present study was determination of number changes of mast cells in a honey treated experimental model of third degree burn. A third degree burn was made in 24 adult female rats by direct contact of skin with boiling water for 8 seconds. Rats were divided randomly into four groups. Group 1: Burns of this group remained untreated (control group). Groups 2 and 3: Burns of these grou...
