Deneysel diabet modelinde solanum nigrum meyve ekstresinin antioksidan ve antihiperlipidemik etkisi

Diabetes mellitus (DM) is a chronic metabolic non-communicable disease; it is globally considered as the fifth cause of death and it has attained worldwide epidemic proportions. In addition, extracts of several herbal medicines have been used and recommended to have potential therapeutic effects on diabetes and its complications. Extracts from Solanum nigrum Linn (European black nightshade) which belongs to Solanum genus and Solanaceae family has been reported to exhibit anti-tumor activity against different types of cancers and significant antidiabetic activities against diabetes. In our study, we aimed to investigate the diabetic effects of Solanum nigrum extract using the control group (C), diabetes group (D), groups given the Solanum nigrum extract (SN) and (D + SN). Our results observed the biological effectiveness of Solanum nigrum extract on glucose levels, significant increasing of serum glucose level group (D) (663 ± 21.8 mg/dL) in comparison with C (131 ± 9.8 mg/dL) were recorded. However, there were no significant difference in glucose level between C group (131 ± 9.8 mg/dl) and SN group (196.14 ± 12.1 mg/dL). Moreover, glucose level of D+SN group (484.8 ± 40.0 mg/dL) was significantly higher than C (131 ± 9.8 mg/dl), D (663 ± 21.8 mg/dl) and SN groups (196.14 ± 12.1 mg/dL). Furthermore, despite noticeable changes in blood levels of Cholesterol, triglyceride, HDL, LDL and VLDL in response to the respective extract, results showed no significant differences in levels of those parameters between all groups. These results might reflect non antihypercholesterolemia and hypotriglycemia effects of the extract of Solanum nigrum. These results might be due to the changes of biological and therapeutic activities of this plant according to where is grown and its cultivars are being cultivated. Total antioxidant status (TAS) level in D group (1.85 ± 0.15.7) was significant when compared C group (1.28 ± 0.17). However, significant differences were observed between D group and D+SN group (1.54 ± 0.07).TAS levels showed no significant difference in both SN (1.27 ± 0.10) and D+SN (1.54 ± 0.07) groups in comparison to control. Total oxidant status (TOS) level in D group (6.30 ± 1.41) was given significant differences in comparison with control C (3.87 ± 0.34), SN (4.87 ± 0.80) group and D+SN (4.14 ± 0.34) groups. In contrary, there were no significant differences between all of C, SN D+SN groups. These results suggest an imbalance between antioxidant defense and free radical generation which has an important role in the progression of diabetic complication. The extract of this plant might have therapeutic effect on patients with diabetes. As a result, we can say that the solanum nigrum plant extract is effective on diabetes, but it can not lower the glucose level to normal levels, it needs to be investigated in future studies and its effects at different doses by different extraction methods..
