ABSTRACT
Bee venom (BV) showed therapeutical effects to treat various diseases as it contains at least 18 pharmacologically active components including various enzymes, peptides, and amines. This study aimed to evaluate the action of BV on some hematological parameters, humoral and cellular immunity, and the determination of antioxidant levels in male albino rats. The study included 40 male albino rats (190-210 g), divided into four groups. Three groups were injected subcutaneously with three different doses of BV (2.5, 5, and 10 mg/kg, respectively). The control group was injected with saline solution. Blood samples were obtained to measure total leucocytes count (TLC), differential leukocytes count, hematological parameters (hemoglobin (Hb), hematocrit (HCT), red blood cells (RBCs), mean cell volume (MCV), mean cell hemoglobin (MCH), mean cell hemoglobin concentration (MCHC) and Platelets. Sera were used to assess immunoglobulins (IgM, IgG, IgA, and IgE), some cytokines e.g., tumor necrosis factor-alpha (TNF-α), tumor growth factor beta (TGF-ß), interleukins 6 and 10 (IL-6, IL-10), and some antioxidant levels malondialdehyde (MDA), super oxide dismutase (SOD), and glutathione (GSH). Data showed that BV therapy increased antibody production levels (IgM, IgG, and IgA) while decreasing IgE levels. Hematological markers (Hb and lymphocytes) were increased. BV increased total TGF- ß and IL-10 but decreased total TNF- α and IL-6. On the antioxidant scale, an increase in SOD, CAT, and GSH levels was observed, accompanied by a decrease in MDA levels. However, the BV treatment led to a significant reduction in the number of eosinophils, monocytes, and neutrophils (p < 0.05). In conclusion, our findings suggested that BV may be utilized to increase the effectiveness of various immunological and hematological parameters.
