Cholesterol, an essential lipid produced by liver, plays a vital role for normal body functioning. It is important in cell membranes as it regulates the membrane over a range of physiological temperatures. However, an excessive amount of cholesterol in the blood can significantly raise the risk of arterial disease (Zhang et al. 2012). Public concerns about the risks of high cholesterol levels in blood began to rise in the 1980s. The normal level of cholesterol concentration in blood is 0.2–0.1 g dl−1 (Ikonen 2008). The high levels of cholesterol in the blood serum lead to coronary heart diseases, hypertension, atherosclerosis and dysfunction of the lipid metabolism (Zhang et al. 2013).

Strange as it may seem, high-density cholesterol (HDL) is a good kind of cholesterol. As the cholesterol package is carried in the blood, HDL not only carries less cholesterol than LDL but also seems to carry cholesterol back to the liver where it can be reprocessed or excreted. The level of blood cholesterol is lowered by the consumption of soluble fibers, monounsaturated or polyunsaturated fats, fatty fish, and by aerobic exercise. The level of blood cholesterol is raised by eating foods high in saturated fat, by eating foods such as eggs or organ meats that are high in cholesterol, by having excess weight, or by smoking (Health Letter Associates, 1991).

Cholesterol is a precursor to the synthesis of bile acids. About 80% of the cholesterol is metabolized by liver tissue and converted to bile acid, which is involved in the enterohepatic circulation. Finally, part of bile acid is reabsorbed by the body.[36,37] de Aguiar Vallim[38] reported that bile acids can bind some food ingredients and then excrete with the digestion of food. Therefore, Cholesterol will be continuously converted to bile acids to maintain the homeostasis of the bile acid pool, thereby reducing the cholesterol content in the blood. In the human body, bile acids are classified into free bile acids (cholic acid, deoxycholic acid, etc.) and conjugated bile acid (cholic acid, deoxycholic acid, etc. combined with glycine and taurine).[39] The conjugated bile acids are generally present in the form of sodium salts, which is more common in the human body. Therefore, in this study, it is applicable that sodium taurocholate and sodium cholate were selected as representative of the conjugated bile acids.

Atorvastatin is used to reduce the biosynthesis of cholesterol by inhibiting the precursor enzyme 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. The applied dose of 0.5 g atorvastatin calcium trihydrate (Sigma – Aldrich, company) was dissolved in 1 mL 70% ethyl alcohol and diluted with 50 mL saline solution. Applied dose of 1 mL3 containing 10 mg/kg body weight was administered by sterile stomach tube on alternating days from the 6th day of conception, during gestation and lactation period up to 21 days post-partum [29].

Moreover, antibacterial efficiency is higher than antifungal activity. Antimicrobial activity against bacteria may be due to the difference between cell structures of bacteria and fungi. While the cell walls of fungi contain chitin, the cell walls of bacteria contain murein [55]. The cell walls of fungi contain chitin, which enhance the rigidity and structural support. In addition, fungi contain ergosterol in cell membrane instead of cholesterol in the cell membrane of animals [9, 54, 60].
