Objective: This study aims to explore the adjuvant effect of multi-strain probiotics with either saffron, cardamom, ginger, or cinnamon herbs to achieve synergistic management for controlling type 2 diabetes (T2D). Methods: Eighty-eight adult male, Wistar rats were used. Eight rats were kept as healthy control. Eighty rats were used to induce type 2 diabetic rats (T2DR) and were randomly assigned to ten groups. One group was an offer to 0.2 ml multi-strain probiotics orally. The rest of T2DR were gavage with 100 mg/kg aqueous extract of saffron, cardamom, ginger, or cinnamon without or with 0.2 ml multi-strain probiotics orally. Bodyweight gain (BWG), and feed efficiency ratio (FER) were recorded. Determination of oral glucose tolerance test (OGTT), serum insulin, C-peptide, HDL, LDL, HDL/total cholesterol ratio were performed. Serum antioxidant activity, Th1and Th2 cytokines and histopathology of the pancreas were done. Results: Comparable with T2DR, solely multi-strain probiotics or with herbs caused a significant reduction in BWG (P<0.05). Groups fed saffron, cardamom, and ginger and enriched with multi-strain probiotic showed significant improvement in OGTT, serum insulin, C-peptide and lipid abnormalities (P<0.05) compared to T2DR. Besides, they had antioxidant and anti-inflammatory effects. The group received ginger alone exerted anti-hyperglycemia and anti-inflammatory effects. However, cinnamon had a moderate anti-diabetic effect and solely probiotics did not show a significant benefit for all parameters except BWG. Conclusion: Cardamom, saffron, and ginger enriched with multi-strain probiotics achieve a synergistic relationship for managing T2D. This finding exhibits a possible new hypothesis to manage diabetes that needs further study.
The male reproductive function, particularly the testes, and the related hormones are sensitive to various xenobiotics. This work aimed for the first time to assess Nigella sativa floral honey (NS floral honey) and multi-floral honey (M-floral honey) versus Nigella sativa oil (NS oil) against rat testicular degeneration induced with azathioprine (AZA). A total of 40 male Wister rats were assigned into 5 groups: (1) control, (2) 15 mg/kg of AZA, (3) AZA + 1.4 mL/kg of M-floral honey, (4) AZA + 1.4 mL/kg of NS floral honey, and (5) AZA + 500 mg/kg of NA oil. Total testosterone (TT), free testosterone (FT), free androgen index (FAI), gonadotrophins, sex-hormone-binding globulin (SHBG), apoptosis markers, and redox status were assessed to clarify the possible protective mechanisms. Pituitary–testicular axis disruption, apoptosis markers, poor redox status, and sperm quality (count, viability, and motility) were set with AZA. Serum TT, SHBG, and absolute and relative testis weight were significantly restored in the NS oil and NS floral honey groups. Meanwhile, the NS oil group exhibited a significant elevation in FT and FAI. Serum gonadotrophins increased significantly in the NS floral honey (p < 0.01) and M-floral honey and NS oil (p < 0.05) groups. Testicular caspase-3, caspase-9, and nitric oxide showed significant improvement in the NS floral honey and NS oil groups. NS oil supplementation significantly normalized redox status (p < 0.05), whereas NS floral honey improved malondialdehyde and superoxide dismutase activity. Sperm quality exhibited a significant improvement in the NS oil group (p < 0.05). M-floral honey did not show reliable results. Although NS floral honey could protect against testicular damage, it did not upgrade to the level of improvement achieved with NS oil. We claim that further clinical studies are essential for focusing on the quality and quantity of bioactive constituents.
Immunity is a major concept in human nutrition. Immunocompromised individuals are at risk for serious infection as COVID-19 which is directed the researchers to use the immunomodulatory plants for prophylaxis. This study was designed to assess the immune response of Wistar rats administrated Achillea fragrantissima (A. fragrantissima) extract versus Endoxan (immunosuppressive) and Echinaid (immune stimulating). Fifty rats were assigned into 5 groups: (1) control, (2) injected intraperitoneal (i/p) with Endoxan 90 mg/kg for three successive days, (3) injected with Endoxan as (2) and administrated with Echinaid 300 mg/kg/day. (4,5) injected with Endoxan as (2) and administrated with 300 and 500 mg/kg/day A. fragrantissima extract respectively. On day 17 all groups were challenged with two doses of sheep erythrocytes (SRBC) i/p, 2 weeks intervals. A high dose of A. fragrantissima extract achieved an increase in total antioxidant capacity significantly(P<0.05), superoxide dismutase, and a decrease in malondialdehyde. Catalase exerted a significant increase with a low dose of A. fragrantissima whereas a high dose had a mild effect. Echinaid and A. fragrantissima raised IgM for the first dose of SRBC and Igs and IgG for the second dose significantly (P<0.05). A. fragrantissima administration ameliorates cytokines (TNF-α, IL-4) and modulated IL-10 significantly (P<0.05). A high dose of A. fragrantissima extract exerted a significant reduction in splenic non-cellular viability% and the highest score of the microscopic immune reaction (immunostimulation++++). Splenic histopathology confirmed the present results. The current study highlights that a high dose of A. fragrantissima extract is preferred over a low dose to restore immune responses in vivo.
