BackgroundTo investigate the pharmacological actions of three groups of drugs containing: Plantago major L. extract, Calendula officinalis L. extract, or mixtures of both. The three investigational drugs were compared to Omeprazole, a standard drug produced in Bulgaria, which inhibits the release of enzymes of the secretary cells of the mucous membranes of the stomach.Materials and MethodsThe effects of the medicinal substances were investigated on “Wistar” breed of white rats. Pathological model of ulcers was formed by injecting the rats with 10% acetic acid (Okabe, Koth.S 1978).The experimental animals were given any of the three versions of the new herbal medicine and compared to the rats given Omeprazole. After treatment the ulcer index, MDA and sialic acids in the serum were determined.ResultThe results showed that in the third day of the investigation, the sialic acid levels in the blood of the test group, which was given the mixture of the two plants, was significantly reduced (p<0.05) compared to the control group.ConclusionThis indicates that medicinal substances given to the rats, which contained the mixture of Plantago major L. and Calendula officinalis L. has accelerated the regeneration of the stomach, decreased the stomach cell damage and overall has antioxidant protective effects.

BackgroundPreliminary clinical studies indicate that liver extract may be helpful in treating hepatic dysfunction. In addition, liver extract seems to work synergistically with interferon in treating hepatitis C and other viral infections. Laboratory studies indicate that liver extract may have some effects that could be useful in treating certain forms of cancer, such as ability to direct migration of metastasizing cells and inhibition of DNA, RNA and protein formation. More research is needed in these areas to determine liver hydrolysate’s properties.Materials and MethodsSeveral biochemical methods were used for determination of chemical compounds in liver extracts: Total protein and nitrogen content was determined by Kjeldahl method; mineral contents – atomic absorption spectrophotometer; Heme iron content – spectrophotometer; Water soluble vitamins - HPLC method. The pharmacological activities of bovine liver were tested by several pharmacological methods: Acute toxicity – LD50 /Prozorovskii 1978/; Acute hepatitis – Carbon tetrachloride (CCl4) induced liver damage in rats /Skakun et al, 1984/; Biochemical parameters in blood serum – Automatic biochemical analyzer.ResultThe values obtained in determination of the biochemical analysis show that 100 g consumption of studied liver hydrolysate can provide 4.3, 2.1 and 0.3 mg vitamin B1, B3 and B9 respectively. Therefore, present data reveal that liver hydrolysate is a good source of most of the analyzed minerals. The liver hydrolysate contains 56.4% total protein and 4.33% amino nutrient.Conclusions:1. From the results of pharmacological study that involves CCl4 induced acute toxic hepatitis, liver hydrolysate has hepatoprotective effect by protecting the liver cells from injury, improving the regeneration process and by correcting metabolic functions of the liver.2. When tested, hydrolysate’s pharmacological parameters can be analyzed reliably with several liver damage experimental designs, further improvements or the use of new designs such as anemia is needed in further pharmacological study.

BackgroundLiver protecting effect of liver hydrolysate is studied on CCl4 induced by acute toxic hepatitis on rats compared with “Raw Liver Glandular” which is similar product of “Swanson”, USA. Result was confirmed with histological study.Materials and MethodsCarbon tetrachloride-CCl4 is considered as a direct hepatotoxin which produces centri-lobular necrosis and steatosis. The mechanism of acute toxic hepatitis induced by CCl4 involves lipid peroxidation of membrane bound fatty acids which result in destructing the cell membrane and the intracellular organells of the hepatocyte.Result:As study result, after 7 days CCL4 exposure, experimental group’s serum ALAT (p<0.01), GGT (p<0.05) and ALP (p<0.05) levels decreased rapidly compared with control groups.ConclusionAlthough, liver hydrolysate is not medicine for treatment liver damage, it might be improved regeneration process in the damaged liver cells. As result, histomorphological study came to the following conclusion: in the seventh day of the model of acute toxic hepatitis of the liver in rats, cytoplasm vacuoles of hepatocytes were decreased sharply, hepatocytes became multilateral, “Kupffer cells” were increased, young hepatocytes were streamlined as columnar-cells, capillaries were became visible and was began regeneration. There were reported that bovine and pork protein hydrolysate contains essential amino acids with antioxidant effect which prevents liver cells from oxidative stress. Besides it, liver hydrolysate containing amino acids, vitamin B1, B6, folic acid and some minerals improves metabolism and regeneration process of damaged liver cells.
