Psychopharmacological impact of ferulic acid on depressive-like behaviors induced by high fat diet in rats models of depression.

Previous studies have been demonstrated that high fat diet can leads to the development of obesity. Obesity is strongly linked with several kinds of neurological and physiological disorders such as type 2 diabetes and cardiovascular diseases. Furthermore studies also suggested that obesity may cause behavioral changes that mainly deal with less locomotor activity and anxiety obesity linked behavioral changes induced by HFD. By using different parameters like growth rate, food intake, levels of anxiety and locomotor activity the finding of this study showed that, that repeated administration of ferulic acid has great profound effect on impairments that were caused by HFD. In our experiments we have observed that those rats which were on HFD and were treated with water only was seemed to be more depressed, less active, and more anxious than those which were administered by ferulic acid doses. From these results we can also suggest that there must be disturbance in the levels of neurotransmitters in an obese individual that caused such kind of changes in the body. This study has implications in the recovery of the changes in the body that were produced by HFD. And ferulic acid can be used as the drug to cure behavioral consequences that were induced by HFD.

Assessment of neuropharmacological consequences induced by dexamethasone administration in rats model of neurodegenerative diseases.

Stress is a well-known and frequently used term among present generation. It has been referred to the response of body to any challenge for a change. It is a natural process and our body is designed to cope with it. However, if stress becomes chronic, it can lead to mental health problems. Stress due to the prolonged administration of glucocorticoid is enabled to produce impressive alterations in rats model shoeing depressive like behavior. In this investigation; purpose was to study the impact of episodic treatment of dexamethasone with respect to behavioral changes in rats. It was hypothesized that repeated administration of dexamethasone could increase stress and thus, psychological stress leading to mood disorders and behavior deficits in rats. Rats were injected daily with DEX (10 mg/ml/kg, orally) and the different behavioral models of the animals were assessed. DEX-treated rats exhibited depressive behavior like greater time to start mobility in a novel environment and elevated anxiety-like behavior in elevated plus maze. However, time spent in light compartment was shorter with repeated administration of DEX. From results it is demonstrated that the administration of DXM for weeks induced stress and consequently, induced a depression-like behaviors in rats models.
