چکیده مقاله :
شکل گیری طاول و زخم ها ی شدید در محوطه دهانی گاوهای مبتلا به تب برفکی و کافی نبودن روش هـای درمانی موجود، معمولاً خسارات زیادی را به گله های درگیر وارد می کند. عصاره گیاه علف چای یا گل راعی (Hypericum perforatum) و ماده موثره هایپریسین موجود در آن، در شرایط آزمایشگاهی به عنوان سرکوبگر تکثیر ویروس تب برفکی مطرح شده و همچنین نقش موثری در بهبود انواع زخم ها داشته است. مطالعه حاضر با هدف بررسی اثرات درمانیِ عصاره گیاه مذکور بر ضایعات دهانی ناشی از بیماری تب برفکی در گاوهای مبتلا انجام گرفت. بدین منظور، تعداد 72 رأس گاو مبتلا به بیماری مذکور (36 رأس در سه گروه تیمار 12 تایی و 36 رأس در سه گروه شاهد 12 تائی)، در سه کانون درگیری در استان آذربایجان غربی انتخاب شدند. تعیین سروتیپ به روش تثبیت کمپلمان، حاکی از درگیری دام‌های مورد مطالعه با سروتیپ O ویروس تب برفکی بود. گل راعی به روش خیساندن عصاره گیری شده، غلظت‌های 25/0، 5/0 و 5 درصد از عصاره هیدروالکلی آن تهیه شد. در گروه های شاهد از سرم فیزیولوژی و در گروه های تیمار از عصاره با غلظت های مذکور به صورت اسپری دهانی (روزی دو بار به مدت 4 روز) استفاده شد. دام های تیمارشده با عصاره 5 درصد بهبودی چشمگیری در ضایعات دهانی داشته و ترمیم ضایعات در دوره درمان اختلاف معنی داری با گروه شاهد داشت (05/0>p ). نتایج حاکی از این بود که اسپری عصاره 5 درصد گل راعی بر روی ضایعات دهانی ناشی از بیماری تـب برفکـی، اثرات بهبودی قابل توجهی دارد.
چکیده انگلیسی:
Formation of excessive blisters and sores on the mouth of affected cattle with Foot-and-Mouth disease and the insufficiency of existing therapeutic methods, leads to extensive damages to the affected herds. The extract of Hypericum perforatum and its active ingredient, Hypericin, have inhibitory effects on the adsorption ability of Foot-and-Mouth virus to host cells in vitro. The medicinal plant also has an effective role in healing various kinds of wounds. The aim of this study was to evaluate the efficacy of H. perforatum extract on the healing of FMD oral lesions in affected cattle. In this study, 72 affected cattle (36 heads in 3 treatment groups of 12 and 36 heads in 3 control groups of 12) from 3 conflict centers in West-Azarbaijan province were selected. Determination of serotype by complement fixation method indicated that the studied animals were infected with serotype O of FMD. Dry aerial parts of H. perforatum were extracted with maceration method and 0.25, 0.5 and 5% concentrations of hydroalcoholic extract were prepared. In control groups, normal saline solution and in treatment groups, the extract with the mentioned concentrations was used as an oral spray (twice a day for 4 days). Cattle treated with 5% extract had a significant improvement in oral lesions and lesion repair during the treatment period was significantly different from the control groups (p<0.05). The results showed that spraying 5% concentration of H. perforatum extract had significant healing effects on oral lesions caused by FMD.
