BACKGROUND Blood collected in an anticoagulant can be kept refrigerated in an unmodified state within 5 - 6 weeks. Oxidative damage is considered to be a one of the major factors contributing to the development of storage lesions. Lipid and membrane proteins oxidation results in changes in cation gradients that affect the cell survival. AIM In the present study we used the natural antioxidant...

Aims: To clarify the usefulness of preservative-free ophthalmic preparations equipped with a filter. Methods: A total of 1,615 samples of in-use ophthalmic preparations were examined for microbial contamination. Results: Of 1,094 samples of preservative-containing ophthalmic preparations, 31 (2.8%) showed microbial contamination. Of 289 samples of preservative-free ophthalmic preparations witho...

Fish sausage is ground fish meat, or a mixture primarily of ground fish with ground pork, together with vegetable oil, permissible preservatives, seasoning and starch. It is packed in a casing and processed. It is a semi-processed food, the time and temperature of processing of the product being not sufficient o kill all micro organisms. Thermotolerant and spore-forming bacteria survive the pro...

Despite the fact that researchers have been working on preservation of raw milk at room temperature for several decades, most processes are limited to use chemical preservatives. One major problems self-life is its spoilage ambient during summer season. Therefore, in present study, research has conducted control 4 °C and 35 (considered different regions’ temperatures). ε-Polylysine, a natural p...
