Efficiency of different levels of Satureja hortensis L. (Savory) in comparison with an antibiotic growth promoter on performance, carcass traits, immune responses and serum biochemical parameters in broiler chickens
This study was conducted to examine the effects of different levels of Satureja hortensis L. (Savory) in comparison with an antibiotic growth promoter (flavophospholipol) on performance, carcass characteristics, immune responses and serum biochemical parameters of broiler chicks. In this study, 240 one-day-old mixed sex broiler chicks (Ross 308) were weighed and randomly allocated to the 4 treatment groups, each with 4 replicates and with 15 broilers in each replicate. The dietary treatments consisted of the basal diet (control), antibiotic group receiving 4.5 mg/kg flavophospholipol, and 5 and 10 g/kg savory powder added to the basal diet. Performance parameters were measured in the growth periods. At day 42, two birds per replicate were slaughtered for the determination of carcass traits. Antibody titers against newcastle, influenza viruses and sheep red blood cell (SRBC) were determined. At day 42, biochemical parameters such as albumin, protein, triglyceride, total cholesterol, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) of cholesterol were determined. The results show that supplementing 5 g/kg savory improved body weight of broilers at days 14, 28 and 42 but differences did not show statistical significance. Feed intake and feed conversion ratio (FCR) index were not markedly affected by dietary treatments. Internal organ weights and carcass characteristics were not significantly influenced by the dietary treatments at day 42. The use of 5 g/kg savory powder led to the highest antibody titers against SRBC as compared to other groups (P<0.05). The serum biochemical parameters were not affected by dietary treatments. The results suggest that dietary inclusion of 5 g/kg savory can be applied as alternatives to in-feed antibiotics for broiler diets.Key words: Broiler, growth performance, immunity, Satureja hortensis L., biochemical parameters
Adipose-derived stem cells for wound healing
Wound healing is a complex but a fine-tuned biological process in which human skin has the ability to regenerate itself following damage. However, in particular conditions such as deep burn or diabetes the process of wound healing is compromised. Despite investigations on the potency of a wide variety of stem cells for wound healing, adipose-derived stem cells (ASCs) seem to possess the least limitations for clinical applications, and literature showed that ASCs can improve the process of wound healing very likely by promoting angiogenesis and/or vascularisation, modulating immune response, and inducing epithelialization in the wound. In the present review, advantages and disadvantages of various stem cells which can be used for promoting wound healing are discussed. In addition, potential mechanisms of action by which ASCs may accelerate wound healing are summarised. Finally, clinical studies applying ASCs for wound healing and the associated limitations are reviewed.Alireza Hassanshahi, Mohammadhossein Hassanshahi, Samira Khabbazi,
