The present study was performed to evaluate the effect of medicinal plant extract on relieving hangovers in mice administered alcohol. The animals were divided into three groups. Each group was treated with fermented plant extract, non-fermented plant extract, or water 30 min after consuming ethanol (2 mL/kg). A locomotor activity test showed that all groups had decreased motor activity until 40 min after plant extract administration. The mice treated with water had lower motor activity until 100 min post-administration. However, the group treated with non-fermented plant extract showed increased motor activity 40 min post-administration, and the higher activity level was maintained until 120 min post-administration. The animals treated with fermented plant extract had a level of motor activity between those of the groups treated with water or non-fermented plant extract. Blood was collected from each mouse 120 min post-administration and aldehyde concentration was measured. The group treated with non-fermented plant extract had a significantly higher (p 0.05) aldehyde concentration than the other groups. These results demonstrate that the non-fermented medicinal plant extract helped alleviate hangovers 40 min after administration by reducing aldehyde concentrations in the blood.

Resistance to antibiotics is a problem all over the world, and this problem also is so extended in veterinary fields. Therefore, this study aimed to find out the antibacterial substances from natural medicinal herbs against bovine mastitis pathogens, especially methicillin-resistant Staphylococcus aureus (MRSA). Among seventy two medicinal herbs, Terminaliae chebula extract showed antimicrobial effect against MRSA isolated from mastitis milk in cow and patient in human. However, Terminaliae chebula extract didn't show antibacterial effects on various strains including other contagious and environmental pathogens related with mastitis of dairy cows.

This study evaluated the antibacterial effects of a mixture of Sophorae radix and Glycyrrhiza uralensis Fischer (1 : 1) ethanol extracts (SGE) on mice infected with Streptococcus (S.) pyogenes. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration of SGE necessary for antibacterial effects against S. pyogenes were 20§¡/mL. Based on the time-kill curves for S. pyogenes, SGE was effective at 4 ¡¿MIC after 16 h. On Day 12 after challenge, the survival rate of mice treated with 2.0 mg/kg SGE was 60%. In conclusion, SGE had potent in vitro and in vivo antibacterial activities against S. pyogenes.

To assess the antioxidative activity of 12 medicinal plants on lipid peroxidation, twelves traditional medicinal plants extracted with 95% methanol were investigated the antioxidative activity using DPPH, thiocyanate acid method, and thiobarbituric acid (TBA) methods. Out of 12 medicinal plants extracted with methanol, the extraction yields of Sedum kamtschaticum was the highest values (49.46%) among them and Geranicum sibiricum, Saururus chinensis root (R), Agrimonia pilosa leaf (L), Agrimonia pilosa root was the lowest value (9.97%). Radical scavenging effect of the selected traditional medicinal plants extracted from different extract solution were examined by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical method.

In the conditions of the Republic of Belarus by an example model of a purulent wound at rats there was realized an experimental study of pharmacological activity of a medical remedy PhytoMP (containing active substances of Macleaya microcarpa (Maxim.) Fedde of Papaveraceae family; and Plantago major L. of Plantaginaceae family) in the form of powder. It was established, that the intensity wound-healthing effect depended on a ratio of the components plume poppy / greater plantain 1 + 1:1, 2:1, 1:2. Studying of the remedy safety showed that PhytoMP in the maximal dozes was not toxic for animals after a single unitary intragastric administration in dose of 50000 mg/kg to mice and in dose of 20833 mg/kg to rats. The mentioned above indexes surpassed the recommended for human dose after application tonsilles (1,428 mg/kg) in 35014 and 14589 times, and also the recommended for human doses for application at a wound with size of 2x2 square cm (11,424 mg/kg) - in 4377 and 1824 times, respectively.

In the conditions of the Republic of Belarus there was studied the propagation, botanical characteristic, chemical composition and pharmacological properties of marsh cinquefoil (Comarum palustre) and its application in the veterinary practice against strongylatosis (Strongylata) of gastrointestinal system of cattle young stock. Reserch results showed that the perennial herbage plant marsh cinquefoil from Rosales (Rosaceae) family possessed different therapeutic properties: antipyretic agent; styptic agent; diuretic agent; bonding agent; wound healing substance; tonic agent; promotoring agent. Research results showed that the preparative forms (broth; liqueur; liquid juice; powder) of marsh cinquefoil possessed an active agent proanthocyanidin, a condensed tanning substance which were included into composition of a polyphenolic complex and proved to be efficient for treatment of cattle young stock strongylatosis.

Results of studying the local of irritating properties of preparative forms of marsh cinquefoil (Comarum palustre) which were intended for treatment of parasitic of diseases of animals, namely, strongylatosis of gastro-intestinal tract of sheep and calves realized in the conditions of the Republic of Belarus were presented. Preparative forms of Comarum palustre (liquor, tincture, liquid extract and powder) had poorly expressed irritating properties after application into skin of animals and weak irritating action, excluding native forms of tincture and liquid extract on mucous coat eye, that confirms their low toxicity action as a whole on organism of animals.
