The aim of this study was to compare the antimicrobial activity of essential oils and extracts of Salvia officinalis, Thymus vulgaris, Mentha piperita, Juniperus communis and Rosmarinus officinalis with antibiotics against physiological and pathological strains of microorganisms isolated from the oral cavity. The antibacterial and antifungal activities of essential oils, extracts and antibiotics were evaluated using the disc diffusion method. Essential oils exhibited higher inhibitory activity against physiological microflora and all tested pathogenic microorganism strains than those observed for antibiotics and plant extracts. Essential oils and ethanolic extracts of Thymus vulgaris were the most potent growth inhibitor of all microorganisms isolated from the oral cavity. Depending on the bacterial strain tested, Thymus vulgaris oil had 3–8 times higher inhibitory activity compared with all tested antibiotics and exhibited the same strength of antifungal activity as amfotericin and miconazol against Candida albicans. Essential oils and extracts may be useful in the prevention and treatment of oral diseases caused by oral microorganisms.

ABSTRACT The presence of oestrogen inhibitory activity in oat hay (Avena sativa) and Fahli clover hay (Trifolium alexandrinum var. Fahli) has been established. The antioestrogenic effect was demonstrated by the inhibition of uterine weight increase in rats (Astwood test) in response to oestradiol injected together with the above mentioned plant extracts. The extraction procedures are described in detail and the possible biological implications of antioestrogenic and oestrogenic activity in fodder plants is discussed.

Изучено влияние на репродуктивную функцию коров белково-витаминно-минеральных концентратов (БВМК) с кормовой добавкой «AMG-COMPLEX», состоящей из эфирных масел и растительных экстрактов. Для проведения опыта были сформированы контрольная и опытная группы по 70 голов с учетом количества дней до отела из коров второй и третьей стельности. Животным контрольной группы скармливали основной рацион. Для коров опытной группы были составлены рационы с БВМК, которыми заменяли пропорциональное количество концентрированных кормов и часть витаминно-минерального премикса. Они получали БВМК для сухостойных коров в количестве 300 г на 1 голову в сутки с 60-го по 20-й день до отела и по 200 г на 1 голову в сутки с 20-го дня до отела. После отела 60 дней им скармливали БВМК для раздоя в количестве 1200 г на 1 голову в сутки. Использование БВМК в рационах коров опытной группы способствовало улучшению у них репродуктивной функции и снижению частоты гинекологических заболеваний после отела в 4,5 раза. Индекс осеменения в опытной группе составил 1,73 (P≤0,05), что на 0,76 ниже, чем у животных контрольной группы. Средняя продолжительность сервис-периода в опытной группе составила 87,71 дня (P≤0,01) и была короче, чем в контроле, на 14,72 дня. The effect on the reproductive function of cows of the protein-vitamin-mineral concentrate with the feed additive ʺAMG-COMPLEXʺ, consisting of essential oils and plant extracts, was studied. To experiment, taking into account the number of days before calving, control and experimental group of 70 heads each were formed from cows of the second and third pregnancy. In the scientific and economic experiment, the cows of the control group consumed the feed of the main rations. For the cows of the experimental group rations were made with PVMC, which replaced the proportional amount of concentrated feed and a part of the vitamin-mineral premix. They received PVMC deadwood in the amount of 300 g per 1 head per day from 60th to 20th day before calving and 200 g per 1 head per day 20 days before calving. 60 days after calving they received PVMC lactation in the amount of 1200 g per head per day. Feeding PVMC to cows of the experimental group contributed to the improvement of reproductive function and a decrease in the frequency of gynaecological diseases after calving by 4.5 times. The insemination index in the experimental group was 1.73 (P≤0.05), which is 0.76 lower than in the animals in the control group. The average duration of the service period in the experimental group was 87.71 days (P≤0.01) and was shorter than in the control by 14.72 days.
