Human diseases are becoming more prevalent, necessitating the development of modalities to overcome the challenges of treating various disorders. In the current research, we analyzed the biomedicinal role of Typha domingensis which is an important medicinal plant. The species is traditionally used in the treatment of neurological disorders and skin malignancies. The chloroform (CFTD) and n-butanol fractions of T. domingensis (BFTD) were subjected to chemical profiling through the determination of total polyphenolic contents and GC-MS analysis. The oral toxicity test was applied to investigate the toxicity of the extracts. Antioxidant capacity was analyzed by four in vitro methods: DPPH, ABTS, FRAP, and CUPRAC. The pharmacological potential was evaluated through clinically significant enzyme inhibition assays, thrombolytic, and antimicrobial activities. In silico molecular docking approach was applied to confirm the role of T. domingensis against the enzymes. The polyphenolic quantification revealed that the BFTD was comparatively rich in total phenolic and flavonoid contents (97.14 milligrams gallic acid equivalent (mg GAE/g) and 362.5 milligrams quercetin equivalent per gram of dry extract (mg QE/g DE), respectively), as compared to the CFTD. The GC-MS analysis of the CFTD and BFTD resulted in the tentative identification of 67 and 29 compounds, respectively, with the major components of fatty acids and essential oil. The oral toxicity test revealed the safety and biocompatibility of CFTD and BFTD. Both the fractions showed promising antioxidant activity. Tyrosinase was found as the major enzyme inhibited by BFTD (78.67%) and CFTD (68.09%), whereas the standard kojic acid showed 85.58% inhibition. The inhibition results of acetylcholinesterase and butyrylcholinesterase by BFTD (71.65 and 60.79%, respectively) are higher than CFTD. Both the fractions were found active against various strains of bacteria. Furthermore, the molecular docking studies of the compounds showed a good docking score against all the docked enzymes among which deoxycaesaldekarin C was found with the highest binding affinities in comparison to the standard. The current study suggests that T. domingensis is nontoxic and can be a potential source of phytoconstituents with promising pharmacological potential.
This study was designed to investigate the protective effects of propolis and vitamin E against time-related metal (aluminum chloride)-induced toxicity on the male reproductive system in albino mice (n = 63). Animals were randomly divided into seven groups (n = 9 each). Group I (control) received 0.9% saline solution; group II was given 50 mg/kg of aluminum chloride (AlCl 3 ); groups III and IV were administered vitamin E (150 mg/kg) and propolis (50 mg/kg), respectively; and groups V, VI and VII were administered AlCl 3 + vitamin E, AlCl 3 + propolis, and AlCl 3 + vitamin E + propolis, respectively, for 45 days. Animals were sacrificed; blood and tissue samples were collected (thrice; fortnightly) for the estimation of hormones i.e., Follicle stimulating hormone (FSH), Luteinizing hormone (LH) and testosterone using Enzyme linked immunosorbent assay (ELISA). Testicular histology, testicular weight, sperm count and motility were estimated. Group II revealed a highly significant decrease in LH, FSH, testosterone, testis weight, sperm count and motility. Groups III-VII showed a significant increase in LH, FSH, testosterone, organ weight, sperm count and motility in the 3 rd sampling, as compared to group II. Hence, it is concluded that vitamin E and propolis, acting individually as well as synergistically, mitigate metal-induced timerelated toxicity on the reproductive system and testicular histology of male mice.
Current study evaluated the synergistic potential of propolis and vitamin E against sub-acute toxicity of aluminum chloride on different biochemical parameters and liver histology. Swiss albino mice (n=42) were randomly divided into seven groups. Group I received 0.2 ml of 0.9 % saline solution, Group II received Propolis (50 mg/kg b.w.), Group III received vitamin E (150 mg/kg b.w.), Group IV received AlCl(3) 50 mg/kg b.w., Group V received AlCl(3) + Propolis, Group VI received AlCl(3) + vitamin E and Group VII received AlCl(3) + propolis + vitamin E. Blood and tissue samples were collected after 7 and 21 days. The body weight of the animals significantly increased in all groups except Group IV. The concentration of serum high density lipoprotein significantly decreased in Group IV and increased in Group V, VI and VII. The level of aspartate aminotransferase, alanine transferase, alkaline phosphatase, triglycerides, total cholesterol, and low density lipoprotein significantly increased in AlCl(3) treated group and increased in Group V, VI and VII. Tissue sections were processed and stained by hematoxylin and eosin. Group II showed cellular necrosis. Group V, VI showed decreased number of vacuolization, sinusoidal spacing and macrophage cell infiltration. Group VI showed less degenerative changes in the third week. Vitamin E and propolis in combination with Al provides more protection against AlCl(3) induced toxicity.
The current study envisioned to evaluate time related protective effect of quercetin, alpha lipoic acid and ascorbic acid on liver of mice against sub-acute exposure of zinc oxide (ZnO-NP) nanoparticle. Male Swiss albino mice (n=72) were randomly divided into eight groups (n=9, each group). G1 received saline solution 0.9%; G2 received quercetin (100 mg/kg b.w); G3 received alpha lipoic acid (100 mg/kg b.w); G4 received ascorbic acid (100 mg/kg b.w); G5 received ZnO-NPs (50 mg/kg b.w); G6 received ZnO-NPs with quercetin; G7 received ZnO-NPs with Alpha lipoic acid and G8 co-treated with ZnO-NPs and ascorbic acid for 21 consecutive days. Body weight, hepatosomatic index and plasma biochemical parameters (total protein, albumin, globulin, total cholesterol, triglycerides, high density lipoproteins, low density lipoprotein, aspartate aminotransferase, alanine transaminase, alkaline phosphatase & bilirubin) were estimated. ZnO showed significant increase in body weight and cause alterations in all biochemical parameters. Co-administration of quercetin (100 mg/kg b.w), alpha lipoic acid and ascorbic acid daily along with ZnO-NPs, significantly ameliorate the dramatic alteration in biochemical parameters and hepatocellular necrosis caused by ZnO nanoparticles. Brine shrimp larvae cytotoxicity assay of ZnO nanoparticles showed 0% mortality. Present study concluded that all three active ingredients showed hepatoprotective effects against nanoparticles induced time dependent toxicity.
