Abstract:Aim:The objective of this study is to investigate the hypoglycemic, hypolipidemic, and hepatoprotective effects of the aqueous extract of parsley, basil, and chicory whole plant in normal and dexamethasone (Dex) rats.Materials and Methods:50 female albino rats were used in this study and divided into 5 groups (for each 10). Group (1) fed basal diet and maintained as negative control group. Group (2) received Dex in a dose of (0.1 mg/kg b. wt.). Groups 3, 4, and 5 were treated with Dex along with three differen… Show more

Background:This study was aimed to screen the antihyperlipidemic effect of different fractions of Teucrium polium to obtain the most efficient herbal fraction for isolation of bioactive constituents responsible for hypolipidemic activity.Methods:Chloroform, butanol, and aqueous fractions were obtained from hydroalcoholic extract of T. polium aerial parts using partitioning process. To induce hyperlipidemia, dexamethasone (Dex) was injected 10 mg/kg/day (s.c.) for 8 days. In the test groups, animals received 50, 100 and 150 mg/kg of T. polium hydroalcoholic extract and different fractions orally simultaneously with Dex. Serum lipid profile and hepatic marker enzymes were evaluated using biochemical kits.Results:All treatments, especially chloroform and aqueous fractions, reversed serum lipid markers in hyperlipidemic rats. Maximum reduction in triglyceride (60.2%, P < 0.001) and maximum elevation in high-density lipoprotein (HDL) (35.0%, P < 0.01) was observed for chloroform fraction. Maximum cholesterol-lowering effect (29.0%, P < 0.001) and maximum reduction in low-density lipoprotein were found for hydroalcoholic extract (72.9%, P < 0.001). Aqueous fraction improved all lipid markers at the highest dose. Butanol fraction decreased triglyceride at the lowest dose (43.9%, P < 0.001) and increased HDL (33%, P < 0.05) at the highest dose. There was a significant increase in alanine aminotransferase and aspartate aminotransferase levels in all tested groups compared to normal group (P < 0.001).Conclusions:This study showed strong antihyperlipidemic effect of various fractions derived from hydroalcoholic extract of T. polium. Chloroform and aqueous fractions may be worthy candidates for isolation of bioactive hypolipidemic constituents. However, possible hepatotoxicity should be considered for clinical application.

Section: Screening Of the Antibacterial Activity By Micro Broth Dilution Assaymentioning
During the previous few decades, it has been seen that there is a rapid emergence of pathogens resistant to multiple antibiotics. This has now become a global crisis. Some unexplored or less explored plants also provide some antibacterial, bactericidal and antioxidant properties. The antibacterial, bactericidal effects of extracted essential oils (EEOs) of Thunbergia coccinea, Acacia polyacantha, Polygonum micrpcephallum, Abies spectabilis and Clerodendrum colebrookianum was tested in comparison with standard antibiotics. The methods chosen were disc diffusion and deduction of minimum inhibitory concentration (MIC) by microbroth dilution assays of the EEOs against the bacterial strains.The antioxidant activity was found out utilizing DPPH free radical scavenging assay, MDA, Hydrogen peroxide radical inhibition assay and Superoxide radical inhibition assay (O 2 -). Some commonly used standard antibiotics (metronidazole, amoxicillin, clarithromycin, rifampicin, clindamycin and oxacillin,) were utilized to compare the EEO antibacterial action. Clerodendrum colebrookianum (85.17 ± 3.06 µg MDA/g extract) had a reasonable MDA. Acacia polyacantha in MIC had values of 3.86 ± 0.25 to 6.20 ± 0.16. Polygonum micrpcephallum had excessive H2O2 (48.27 ± 2.4 5%). The antibacterial actions determined by the paper disc‑diffusion technique of the EEO extracted from these plants showed that most had some antibacterial actions. Also, it was seen that the bactericidal action of the EEO extracted from E. alba was most potent against S. pyogenes (4.06 ± 0.15). The extract of the plant at varying concentrations (20, 40, 60, 80 and100 mg/mL) demonstrated noteworthy (P< 0.001) anthelmintic action in an effective change when the dose was adjusted. In conclusion, most of the tested plants contain a medicinal value, which can be utilized in the future to supplement artificial medicines and cure emerging diseases that create havoc for mankind.
“…In the present study four plants (Cichorium intybus Linn., Cucumis melo Linn, Cynomorium coccineum, Cynomorium songaricum) were selected for polyherbal preparation. In the traditional system of medicine different preparations of Cichorium intybus L., commonly known as Chicory or Kasni, have been practiced for digestive and hepatic problems and lower glucose levels and inflammation (22,23). Several studies have reported the antioxidant, inflammation-reducing, and blood-glucose-lowering activities of Cichorium and, to some extent investigating the mechanistic approach also (24)(25)(26)(27).…”
In view of many complications of diabetes, kidney failure is considered as one of the main complications. The oxidative stress-induced due to persistent hyperglycemic conditions is the major cause of kidney disease. The present study was designed to explore the nephroprotective efficacy of polyherbal (PH) extract in a diabetic model induced by streptozotocin (STZ). STZ (55 mg/kg body weight, intraperitoneal) was injected in overnight fasting rats to develop the diabetic experimental model. Effect on kidney injury was evaluated by investigating biochemical and histological evidences in renal tissue after 56 days of treatment of PH extract. Results showed the high glucose level in STZ treated rats that suggested hyperglycemia persistence along with the successful establishment of nephropathy in diabetic rats with altered renal function, inflammatory cytokines level as well as oxidative and nitrosative stress. Administration of PH extract significantly improved the glycemic condition, glomerular function and proximal reabsorptive markers. Further, elevated pro-inflammatory cytokines levels and disturbed redox status were restored. Moreover, findings were fostered and substantiated by histopathological examinations. Our work strongly proposes that the nephroprotective effect of the PH extract on renal damage could be attributed due to its anti-inflammatory and antioxidant properties. Thus, PH extract could have potential as a pharmaceutical drug for diabetes mellitus (DM). Additional long-term study or clinical trial is required for further investigations.
