This study reports in vivo effects of P. pinnata on glucose, lipid and liver in diabetic rats and its possible action mechanism. Stem bark extract of P. Pinnata was prepared using the soxhlet apparatus. Experimental induction of diabetes was carried out by giving a single dose of alloxan monohydrate. Plant extracts treatment was started on the 7th day of the alloxan treatment (i.e. Day 1) as a single dose in the morning and was continued for 3 months with respective groups. Blood was collected from the retro-orbital plexus at specific periodic intervals for three months for the purpose of biochemical investigation. In diabetic rats (DC), the Serum BSF, AST, ALT, TG, TC levels were significantly increased in correlation with Normal control (NC). Treatment with PPAlcExt produced significant reduction in levels of TG (76.06 mg/dl) as compared to DC (200.63 mg/dl), TC (54.6 mg/dl) as compared to DC (89.7 mg/dl), AST (293.28 U/L) as compared to DC (564.09 U/L), and ALT (74.5 U/L) as compared to DC (238.0 U/L). Treatment with PPAqExt and PPAlcExt showed remarkable recovery on all the parameters, while a highly significant reduction was achieved with PPAlcExt treatment. The results proved that hydroalcoholic bioactive phytochemical constituents from plants can be a good alternative to synthetic drugs, and can constitute a potentially novel approach for the treatment of diabetes.","PeriodicalId":15364,"journal":{"name":"Journal of Biologically Active Products from Nature","volume":"11 1","pages":"406 - 412"},"PeriodicalIF":0.0,"publicationDate":"2021-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46023134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In animals pretreated with Eudistoma ovatum (EO) and Didemnum perlucidum (DP) drugs, there was significant and dose-dependent inhibition of Carrageenan-induced posterior paw edema. A variety of antioxidant enzymes, such as Superoxide dismutase (SOD), Glutathione peroxidase (GPx), and Glutathione reductase (GRd) can scavenge and minimize the formation of reactive oxygen species (ROS). SOD protects cells against the damages of ROS. GPx in the presence of glutathione (GSH) accelerates the reduction of H2O2 or other organic hydroperoxides and serves as a second line of defense against hydroperoxides. The amount of platelets is affected by the increased plasma concentration of active proteins in the acute response to inflammation. Anti-inflammatory activity in carrageenan-induced paw edema in rat model was found in the extract of both ascidians E. ovatum and D. perlucidum. But the methanolic extract of E. ovatum showed more significant anti-inflammatory activity. The study includes the investigation on the effects of EO and DP on some oxidative parameters such as lipid peroxidation (LPO), SOD and GSH level, hematological parameters (RBC, WBC and Platelets, cytokines (IL 6 and TNF α), hepatic enzymes (Acid phosphatase - ACP and Alkaline phosphatase - ALP) and membrane-bound glycoproteins (hexose, hexosamine, sialic acid, and fucose).

Therefore, research on drug development from members of natural sources has gained much importance. Lichens are a unique association of fungi and algae, producing a wide array of secondary metabolites which has immense pharmacological activities. Lichen extracts have been used in traditional systems of medicines and are known to cure several diseases. Parmotrema is a large genus of foliose lichen belonging to the family Parmeliaceae. Parmeloid lichens are a diverse and ubiquitous group of lichens. Members of the Parmeliaceae family have been used in several traditional systems of medicines. One hundred and nine articles have been reported till date regarding pharmacological activities of Parmotrema species. Studies reveal that Parmotrema exhibits numerous biological activities ranging from anti-microbial, anti-fungal, anti-oxidative, and anti-proliferative properties. These properties can be attributed to the presence of pharmacologically active compounds like depsides, depsidones, phenolics, polysaccharides, lipids, diphenyl ethers, and dibenzofurans. The free radical scavenging activity and cytotoxicity specifically towards cancer cells infer that this lichen genus can have potential anti-cancer properties and should be extensively investigated for pharmaceutical purposes.
