Abstract

Apicultural products comprise honey, bee pollen, propolis, bee wax and royal jelly which are known for their medicinal and health promoting properties. Among these, bee collected pollen allure much attention for its high nutritional properties. Here, we have investigated the protective role of bee pollen against Salmonella typhimurium induced biochemical alteration in BALB/c mice. Experimental animals (BALB/c mice) were divided equally into 10 different groups including normal and treated. Oxidative stress was induced by injecting Salmonella typhimurium (0.2 mL of 2×104 CFU/mL) intraperitoneally in mice. Bacteria induced sufficient alterations in serum enzymes within 5 days. Aqueous extracts of bee pollen of different crops (250 mg/kg) were administrated orally to control and experimental mice for 21 days. Then, hepatic and renal enzymes were measured with the help of standardized kits. Results of this study have revealed that bacterial infection increases the levels of the hepatic and renal enzymes levels (P <0.001) but after treatment with bee pollen extracts, altered levels of enzymes were normalized up to the normal levels. This normalization was highest with bee pollen of Helianthus annus. Administration of bee pollen alone did not produce any negative effects in mice.
