A Comparative Study of Determination the Spectral Characteristics of Serum Total Protein Among Laser System and Spectrophotometric: Advantage and Limitation of Suggested Methods

Improvement of antibiotics absorption and regulation of tissue oxygenation through blood laser irradiation

A point of this work is to estimate the impact of laser blood irradiation controlled intravenously at the level of an antibiotic. Hundred and twenty grown-up female adult rabbits were utilized in this investigation. They were separated into two equivalent groups relying upon the method for managing of the antibiotic. First group injected with10 mg/kg b. w of Moxifloxacin antibiotic while second group was given the Moxifloxacin but in a type of a tablet, containing 10 mg/kg.b.w orally. Following, each group was partitioned into four equivalent subgroups; control and treated with laser therapy at different time. Gallium-Arsenide (GaAs) laser device, utilized for treatment, in wavelength 904 nm, power of 5mW, its include a connector by optical fiber with fine cannula fixed at its end. Rabbits of laser subgroup; were treated by presenting needle of cannula into ear-marginal vein for 10, 20 and 30min. Blood samples have been collected from both groups after 1, 2, 3, 4, 5 and 6 h intervals after treatment and had transmitted for analysis via a high-pressure liquid chromatography to determine level of Moxifloxacin in blood. The after-effects' revealed a regular increment in Moxifloxacin level (ng/ml) in two groups until 3 h followed with a rapid decline until the end of the experiment. Blood Irradiation through low-level laser enhances the concentration of Moxifloxacin in the serum whatsoever; was the rout of its performance, besides the irradiation help within quickened clearance of blood beginning the drug.

Evaluation of the Significance of Constant Laser Therapy, 532 nm, in Various Exposure Times on the Healing Process of Wounds Infected by Acinetobacter baumannii

Many considerable investigations focused on the stimulation of therapeutic manners of infected injuries in mice. The exaggerated pathogens that induced wounds were gram-positive like staphylococcal and gram-negative, for example, Pseudomonas aeuroginosa and Acinetobacter baumannii. Acinetobacter can generate a scale range of an infection that may be received in a hospital or any wellness concern facility. In order to know the significance of laser 532 nm with a constant irradiance at various exposure times on the healing process of wounds infected by Acinetobacter baumannii, this study was performed on the BALB/C mice. An elliptical full-thickness skin injury was made on the backside of 45 adult female (BALB/C) mice. Injuries were affected via Acinetobacter baumannii and were randomly assigned into 3 groups. Semiconductor diode continuous wave laser, λ = 532 nm, with output power 40 mW was used. The power density was 5.71 mW/cm², while the fluencies were 1.7 J/cm² and 5.14 J/cm². Fifteen mice were classified according to the times of irradiation. The first group was infected and presented as control, without irradiation. The second group was infected and irradiated for 5 minutes. The third group, likewise, was infected but irradiated for 15 minutes. All groups were subdivided according to the following period, 3, 5, and 10 days, after irradiation and the animals were killed after the treatment. Wound healing was made by measuring the rate of wound closure and histopathological evaluation. The study determined that 532 nm laser therapy had an obvious and positive influence on the healing of infected wounds with fluence (5.14 J/cm²).
