PHARMACOLOGICAL EFFECTS OF SILLICHOL ON BILE SECRETION AND / Монголын эм зүй, эм судлал

ABSTRACT

Varieties of plants and lyophilized bovine bile have been used for increase secretion of bile in traditional systems of medicine of various countries. Following many articles note on the benefi cial effects of lyophilized bovine bile particularly on the wound healing and gastric protection effects, there is paucity of reports in literature on its effects on a bile secretion, a bile bilirubin, bile cholesterol and a plasma cholesterol levels. Sillichol contains lyophilizedbovine bile, liver hydrolisate, yarrow extract and silymarin. The aim of this study was to find out the effect of bile fl ow, bile bilirubin concentration bile cholesterol level and hepatoprotective of Sillichol. Sixteen adult male wistar rats (weighing between 200-250 gr) were used in the study. They were randomly assigned into control and sillichol group comprising 4 in each group. Thereafter, they were weighed and anaesthetized with ketamine (2ml/200gr body weight) muscle leg and quickly pinned to a dissecting board. Laparotomy was performed and liver lobes were defl ected anterolaterally to expose the common bile duct. The common bile duct was cannulated with a portex cannula (0.5 mm diameter) after a semitransection was made on the bile duct. The cannuls was held in place with thread tied over it and around the bile duct.The bile was collected for 8 hours from each rat studied according to method of Rozuet Jousse. The rate of bile fl ow was noted, the volume of bilirubin, bile cholesterol levels were determined in the control and test groups. Moreover, total of 18 wistar rats (200-250 gr) were obtainedfrom laboratory house of Drug research institute and acclimated for 10 days before starting the experiment. Liver toxicity was induced by the subcutaneous injection of carbon tetrachloride (CCL4, 0.4 ml/100gr), 11 diluted with paraffi n oil, for four successive days of the experiment (N.P.Scakun et al, 1983). The rats were divided randomly into 3 groups comprising 6 rats in each group and fed the same diet throughout the experimental period. Mean values of bile cholesterol and bilirubinlevels, rate of bile secretion in the control and sillichol group. Bile cholesterol levels were signifi cantly decreased in the sillichol group compared with the control group (60.3±0.88 mg/dl vs 62.6±1.21mg/dl, p<0.05). Rate of bile secretion was signifi cantly increased in the experimental compared with the control group(10.21±0.25 ml/8hr vs 4.18±0.25 ml/8hr, p<0.05). Total bilirubin, conjugated and unconjugatedbilirubin concentrations in both sillichol and control groups were not signifi cantly different (p<0.01). The activities of GOT, GPT and ALP were estimated in serum samples as the liver function biomarkers using biochemical diagnostic test. The CCL4 treatment markedly affected the liverspecifi c enzymes. It was found that a signifi cant (p<0.05) increase in serum GOT, GPT and ALP activities of CCL4 treated rats. After the treats, hepatic biomarkers were elevated in the serum due to release of the enzymes from damaged liver. GOT (69.8±1.5), GPT (103.9±1.2), ALP (23.8±0.2) and Cholesterol (67.7±13.6) andtriglyceride (64.0±3.3) levels weredecreasedsignifi cantly (p<0.05) in the sillichol groupcompared with the control group. Silichol is decreasing concentration of cholesterol and bilirubin’s level in bile, constantly after administration of drug. Also, liverpreparation is increasing bile acid secretion in hepatocytes and a speed of secretion.From the results of pharmacological study concluded that involves CCL4 induced acute toxic hepatitis, liver preparation has hepatoprotective effect by protecting the liver cells from injury, improving the regeneration process and by correcting metabolic functions of the liver.
