Polyherbal Formulation

Several herbal formulation were not properly documented due to poor scientific data as well as poor standard regulation in preparation and marketing. The study evaluate the effect of aqueous extract of Polyherbal formulation on Macrophages’ phagocytic function and Humoral immune response in Mice A total of Sixteen 16 Mice was used. Group I received normal saline, Group II-IV received 500 mg, 1000 mg, and 1500 mg of Polyherbal formulation respectively for 21 days each. The animals were sensitized and challenged with Sheep red blood cells at day 14th and 19th of the treatment respectively. On day 21st all the animals were injected with 0.1 ml Indian ink for carbon clearance assay and blood sample was collected at 1 minute and 15 minutes of the injection. The phagocytic function of Macrophages and humoral immune response were determined spectrophotometrically and Hemagglutination assay respectively. The results show that the highest carbonic particle clearances index (K) median score (Median=0.0228), Macrophage phagocytose index (α) median score (Median=3.249), organ weight index (g/100g) mean score (M=0.06633) and Hemagglutination antibody titre median score (Median=32.00) was recorded by Group IV when compared with other groups. The carbonic particle clearance (K) (p=0.02), phagocytic index of Macrophage (α) (p=0.03), and organ weight index (g/100g) (p<0.0001) significantly increase with increase in the Polyherbal formulation concentration. Hemagglutination antibody titre against Sheep red blood cells (p=0.02) also significantly increased. The extract has potential immunostimulatory activity on both Macrophages’ phagocytic function and humoral immune response in mice thus could be useful in improving immune responses.

The effects of Korean herbal medicine (B.C.L.) on some parametrs of immunological response were studied in mice, B.C.L. pretreatment given either intraperitoneally subcutaneously in a dose of 0.75 mg/mouse did not significantly inhibit lymphocyte transformation induced by concanavalin A. However, B.C.L. pretreatment in a dose of 2.25 mg/mouse was found to reduce significantly both the plaque-forming cells to sheep red blood cells immunisation as well as total splee cell population. Thus, B.C.L. pretreatment with a higher does (2.25 mg/mouse) can selectively depress the humoral immune response. It is unclear, however, whether this action is mediated by the parent compound or its metabolities.

Salmonella infection is a major cause of death in chickens and this disease can be transferred through meat and egg to humans. The use of antibiotics and vaccines in the prevention and control of this infection are not totally efficient and also have their side effects. Therefore, genetic control is a better approach in finding a lasting solution. One hundred and ten chickens (4th generation) comprising the three genotypes of Nigerian indigenous chickens(NIC) that had shown divergent response (high vs low) to sheep red blood cells antigens were used in this study to investigate the immune response kinetics in NIC after challenged with attenuated Salmonella. There were six classes namely, high titre normal, low titre normal, high titre frizzle, low titre frizzle, high titre naked neck and low titre naked neck. Haematological parameters: packed cell volume (PCV), haemoglobin concentration (Hb),red blood cells count (RBC), white blood cells count (WBC), heterophils (H), lymphocytes (L), eosinophils (E), basophils (B), monocytes (M) and heterophils-lymphocytes ratio (HLR) were used to assess the immune responses of the chickens and data collected were subjected to General Linear Model procedure of SAS 9.2 version. The results showed that genotypeantibody titre had significant effect (p<0.05) on the immune response parameters but sex had no significant effect (p>0.05), while sex by genotype-antibody titre interaction had significant effect (p<0.05). The immune response kinetics of the chickens after challenge with attenuated Salmonella was shown by the significance of the effect of days of blood collection after challenge. High titre naked neck chickens recorded the highest PCV, Hb and RBC values while genotype-antibody titre had no significant effect (p>0.05) on the rest of the parameters. Low titre naked neck males recorded the highest PCV, HB and RBC values while the rest of the parameters were not significant (p>0.05). Generally, days had significant effect (p<0.05) on all the immune response parameters except on H, L and HLR. The study showed that the high titre naked neck males were least affected by the Salmonella vaccine in terms of decrease in packed cell volume, haemoglobin concentration and red blood cell count while the low titre normal females were most affected.
