Thermopsis turcica, endemic to Turkey, is in danger of extinction. Studies on this species are very few due to the fact that it was only discovered in 1983 and grows in a small circumscribed area in Turkey. In this study, free radical scavenging activity, total phenolic content, total oxidant status (TOS), and total antioxidant status (TAS) of methanol (TTM) and acetone (TTA) extracts of T. turcica were measured spectroscopically. Free radical scavenging activity was determined according to the elimination of DPPH radicals and total phenol content was determined by the Folin-Ciocalteu reaction. Total oxidant status (TOS) and total antioxidant status (TAS) were measured with commercially available kits. Methanol and acetone extracts of T. turcica were found to have a specific radical scavenging effect. This effect was found to be related to the total phenolic content of the extracts. Since the TTA had a higher phenolic content than the methanol extract, it had a stronger radical scavenging effect. In addition, the total antioxidant capacity of the methanol extract was observed to be higher than that of its acetone counterpart. As a result, due to its antioxidative properties, T. turcica is thought to be a natural source of antioxidants.

Objective:In this study, anti-inflammatory effects of Royal Jelly were investigated by inducing renal inflammation in rats with the use of ethylene glycol. For this purpose, the calcium oxalate urolithiasis model was obtained by feeding rats with ethylene glycol in drinking water.Materials and Methods:The rats were divided in five study groups. The 1st group was determined as the control group. The rats in the 2nd group received ethylene glycol (1%) in drinking water. The rats in the 3rd group were daily fed with Royal Jelly by using oral gavage. The 4th group was determined as the preventive group and the rats were fed with ethylene glycol (1%) in drinking water while receiving Royal Jelly via oral gavage. The 5th group was determined as the therapeutic group and received ethylene glycol in drinking water during the first 2 weeks of the study and Royal Jelly via oral gavage during the last 2 weeks of the study.Results:At the end of the study, proinflammatory/anti-inflammatory cytokines, TNF-α, IL-1β and IL-18 levels in blood and renal tissue samples from the rats used in the application were measured.Conclusion:The results have shown that ethylene glycol does induce inflammation and renal damage. This can cause the formation of reactive oxygen species. Royal Jelly is also considered to have anti-inflammatory effects due to its possible antiradical and antioxidative effects. It can have positive effects on both the prevention of urolithiasis and possible inflammation during the existing urolithiasis and support the medical treatment.

Crocin could contribute to the development of phytotherapeutic approaches in the treatment of obesity, diabetes, and diabesity (obesity-induced diabetes), which is promising as the abovementioned incidences have increased considerably in today's world.

The present study aimed to determine the antioxidative and anti-inflammatory effects of safranal on damage induced by CCl 4. Experimental animals were divided into five groups. The first group was determined as the control group and no treatment was conducted. Second group rats were administered 1 mL/kg-day CCI 4 during the experiment. Rats in Groups 3, 4 and 5 were administered 1 mL/kg-day CCI 4 and 25 mg/kg, 50 mg/kg; 100 mg/kg safranal, respectively via gavage. Oxidative-antioxidant parameters, liver function enzymes and inflammatory cytokine levels were determined in liver samples obtained from the rats. Data analysis demonstrated that oxidative stress and inflammation markers were significantly higher in CCI 4 administered groups (p<0.05). Antioxidant parameters in high-dose safranal administered groups were not different when compared to the control group. Safranal had ameliorating effects on the increased liver function enzymes activities in CCI 4 administered groups. In conclusion, it was observed that CCI 4 administration led to hepatic damage and increased oxidative stress and inflammatory cytokine levels. It was observed that particularly high-dose administration of safranal promoted the antioxidant system. Safranal administration was not effective on IL-1β levels. However, high-dose (100 mg/kg) safranal was found to be inflammatory against TNF-α and IL-6 cytokines. In conclusion, it can be said that safranal has an anti-inflammatory potential and has a strong antioxidative effect.
