OBJECTIVE The purpose of this study was to evaluate, from the histological point of view, the effect of diode laser irradiation on skin wound healing in Sprague-Dawley rats. BACKGROUND DATA Various biological effects have been described in different studies after low-level laser therapy (LLLT). METHODS Two parallel full-thickness skin incisions were(More)
A simple separation method enabling the quantification of alkaline phosphatase activity in unfixed, isolated, individual, duodenal epithelial cells has been presented. The activity of intestinal brush border-bound alkaline phosphatase has been demonstrated using naphthol AS-BI phosphate as a substrate and hexazotized New Fuchsin as a simultaneous coupling(More)
315 Feeding behaviour in socially living species can be affected by manipulation of their environment. Extensive experimental data related to stressful or aversive influences on food consumption demonstrated that tail pinch decreased food intake in rodents. In addition to these influences the social and environmental factors and their complicated(More)
The objective of the present study was to assess the feasibility of using endogenous fluorescence in intraoperative prediction of skin flap necrosis. The investigation was carried out in 10 Sprague-Dawley rats in which proximally based over-dimensioned random pattern skin flaps were dissected on the back and thereafter fixed into position. Immediately after(More)
Optimal parameters of low-level laser therapy (LLLT) for wound healing are still discussed. Hence, our study was aimed to compare effects of different power densities of LLLT at 635 nm in rats. Four, round, full-thickness, skin wounds were made on the backs of 48 rats that were divided into two groups (non-steroid laser-treated and steroid laser-treated).(More)
The aim of this study was to investigate the effect of a high-fat (HF)/energy diet on the intestinal microbiota, the alkaline phosphatase (AP) activity, and related parameters of growth and obesity during the suckling and weaning periods in male Sprague-Dawley rats. From birth, nutrition in suckling pups was manipulated by feeding rat dams either HF or a(More)
The RNA content of the ventromedial hypothalamus (VMH), the lateral hypothalamic area (LHA), and the cortical neurons of male and female rats, neonatally treated with monosodium glutamate (MSG), were investigated. MSG (2 g/kg b.wt.) was injected subcutaneously to male and female rat pups daily for 5 days after birth. At 12 weeks of age a significant(More)
Dorsal lesions of the septum influenced the maternal behaviour of Wistar and Long-Evans females, as well as of their hybrids, in a different way. The phenomenon of infanticide appeared in Wistar females only, whereas mothering was not impaired in others. However, the mouse-killing activity was not enhanced in Wistar females displaying infanticide. On the(More)
Potential changes in the activity of endocrine axes related to growth as a result of leptin administration during embryonic development of birds were evaluated in the Japanese quail as a model bird with fast growth and development. On day 5 of incubation, 0.1 microg or 1 microg of recombinant mice leptin in 50 microl of phosphate buffered saline were(More)
