Kuzgun, Nermin Karaton
Bu çalışmada, farklı konsantrasyonlarda (% 0.1, % 0.5 ve % 1) kullanılan defne esansiyel yağının soğukta depolanan gökkuşağı alabalığı (Oncorhynchus mykiss) filetolarının raf ömrü üzerine etkileri araştırılmıştır. Araştırmada incelenen filetoların 2±1°C’deki muhafazası süresince üç günde bir kimyasal (pH, TVB-N ve TBA), mikrobiyolojik (Toplam aerop bakteri, psikrofilik, laktobacillus, ve maya ve küf grubu bakterilerin sayımı) ve duyusal (Renk, koku, tekstür, lezzet ve genel beğeni) olarak analizleri yapılmıştır. Yapılan analizler neticesinde, taze filetoların 6. günde, % 0.1 defne esansiyel yağı ile kaplanmış filetoların 9. günde, %0.5 defne esansiyel yağı ile kaplanmış filetoların 12. günde, %1 defne esansiyel yağı ile kaplanmış filetoların 15. günde, muhafaza süreleri sona ermiştir. Sonuç olarak, defne esansiyel yağının filetoların raf ömrü üzerinde olumlu etki gösterdiği, özellikle 1% defne esansiyel yağı uygulanmış filetolarda bu konuda kayda değer olduğu ve ürünün kimyasal, mikrobiyolojik ve duyusal kalitesi üzerine olumlu etki gösterdiği gözlemlenmiştir.

The goal of present study is to find the penolic contents, antioxidant activities and antimicrobial capacities in the seeds of five Salvia L. taxa two of which are endemics (Salvia euphratica var. leiocalycina and Salvia euphratica var. euphratica). The flavonoid and phenolic acid are determined by using HPLC while the antioxidant activities are determined based on different methods. Also, the antimicrobial activities of some Salvia species are determined by using the well agar method. The current study found that the studied Salvia species have low flavonoid. It has been found that Salvia euphratica var. euphratica has high vanillic acid, ferulic acid and rosmarinic acid among the studied taxa. Similarly, it has been found that Salvia euphratica var. euphratica has high DPPH and ABTS radical scavening capacity in all concentrations. It has been also found that Salvia euphratica var. euphratica has highest total phenolic content (372,63±0,87 µgGAE/mg) whilst Salvia tricholoda has low total phenolic content (46,41±1,71 µgGAE/mg). In addition, this study demonstrated that Salvia tricholoda has lowest metal chelating activity (37,35±0,51%). Furthermore, present study found that the lipid peroxidation levels of the studied Salvia taxa are between 18,21±0,37 mg/kg and 21,03±0,22 mg/kg while it has been found that the antibacterial properties of the Salvia taxa under study are altering.

The aim of this study was to evaluate the effect of chrysin on testicular damage induced by carbon tetrachloride (CCl4) in rats. Twenty-four male Spraque-Dawley rats were divided into four groups as the control group, Chrysin group, CCl4 group, and Chrysin+CCl4 group. Chrysin (100 mg/kg/body weight/day) and CCl4 (0.5 ml/kg/body weight/day in corn oil (1:1)) were administered by gavage for 14 days. Compared to the control group, it was determined that malondialdehyde (MDA) level increased, reduced glutathione (GSH) level, and superoxide dismutase (SOD) and catalase (KAT) activities decreased in the CCl4 group. It was also determined that many testicular lesions were induced, Johnsen’s Mean Testicular Biopsy Score (JMTBS) decreased, and caspase-3 immunoreactivity increased in this group. Compared to the CCl4 group, it was determined that GSH level and SOD and CAT activities increased, MDA level decreased in the Chrysin+CCl4 group. It was also observed that testicular lesions were alleviated, JMTBS increased, and caspase-3 immunoreactivity was decreased in this group. As a result, it was concluded that chrysin might have beneficial effects in the treatment of CCl4-induced testicular toxicity as a result of its antioxidant and anti-apoptotic properties.
