The unregulated use of antibiotics has emerged as a major driving force antibiotic resistance and public health hazard, particularly in developing countries. This necessitates to find out solution that benefits humans animals. Probiotics are one such alternative; they simply known beneficial bacteria exert living beings. Probiotic microorganisms crucial for the biotechnology food industries. Th...

BACKGROUND To investigate the efficacy of different probiotic strains, their combinations and forms (alive or lyophilized) in nonalcoholic fatty liver disease (NAFLD) prevention. METHODS In this study, 70 rats have been used divided into 7 groups of 10 animals in each: I - intact rats, II-VII - rats with monosodium glutamate (MSG)-induced NAFLD. Rats with NAFLD were untreated (group II, MSG-o...

Isoimmune sera, prepared in BALB/c mice by immunization with living or lyophilized tissue from C57Bl/6 mice, were found to possess both hemagglutinating and cytotoxic activity for donor cells. Comparative titrations indicated a good correspondence between these two activities. Absorbtion with living or dead donor tissue caused removal or proportionate reduction of both activities. The results a...

Gelatin, chitosan and hyaluronic acid are natural components used to prepare polymeric scaffold in tissue engineering. The physical properties of these materials confer an appropriate microenvironment for cells, which can be used as a regeneration system for skin and cartilage. In this work, we prepared and characterized a Gelatin/Chitosan/Hyaluronan lyophilized-polymer. Physical properties of ...

The case of a 67-year-old woman with chronic venous leg ulcers and severe gonarthrosis is described. In spite of intensive therapy, the leg ulcers had persisted for 4 years and made the intended orthopaedic operation of the right knee impossible. The patient was treated with lyophilized cultured epidermal allografts and her leg ulcers healed within 40 days. Lyophilized cultured epidermal allogr...
