هدف از این مطالعه بررسی نقش برخی پارامترهای سرم در تشخیص لیپیدوز کبدی در گاو با توجه ویژه به درجه آن و تعیین بهترین نقطه برش این پارامترها به منظور پیشگویی ابتلا به کبد چرب است. نمونه خون و کبد 28 گاو در زمان کشتار گرفته شد. غلظت سرمی آنزیم های کبدی، بیلی روبین، پروتئین و پروفایل چربی تعیین و نسبت لیپیدهای خون به HDL محاسبه شد. نمره بدنی و سن گاوها نیز ثبت گردید. مدل آماری ROC برای تعیین آستانه های بحرانی برای پیش بینی کبد چرب استفاده شد. با افزایش شدت کبد چرب میزان AST، GGT، کلسترل و HDL افزایش می یابد و می توان از این پارامترها به عنوان یک بیومارکر در شناسایی ضایعات شدید و متوسط کبد چرب استفاده کرد. همچنین با کاهش نمره بدنی و افزایش سن، شدت بیماری نیز افزایش می یابد. آنالیز راک نشان داد که AST، GGT، توتال پروتئین، نسبت کلسترول به HDL و نمره بدنی و سن برای پیشگویی ابتلا به بیماری مناسب هستند. بهترین نقطه برش برای پیشگویی ابتلا به کبد چرب برای AST، IU/L05/55، برای GGT،U/L 14، برای توتال پروتئین mg/dl55/6 و برای نسبت کلسترول به HDL، 18/3 پیشنهاد گردید. بهترین نقطه برش برای نمره وضعیت بدنی و سن به ترتیب 25/4 و 5/6 سال بود. نتایج این مطالعه نشان داد که اندازه گیری آنزیم های کبدی و پروفایل چربی در تعیین درجات کبد چرب در گاوهای هلشتاین در شرایط فیلد از اهمیت تشخیصی قابل قبولی برخوردار است و می تواند روش مناسبی برای جایگزینی بیوپسی کبد باشد. پرونده مقاله

Background & Aim: Free radicals play an important role in the development of some diseases, including gastrointestinal ulcers. Current gastric ulcer drugs have side effects, so the tendency to use herbs and replace them with synthetic drugs has increased. In this regard, plants of the Satureja family have been studied in terms of healing and antioxidant properties. The aim of this study was to evaluate the protective effects of Satureja bachtiarica ethanolic extract on ethanol-induced gastric mucosal ulcers in rats.Experimental: Thirty rats were divided into 5 equal groups. Group 1 received 200 mg / kg of ethanolic extract of Satureja bachtiarica (EESB), group 2 received 400 mg / kg EESB, group 3 received 20 mg / kg omeprazole, group 4 received 1 mL of CMC and group 5 received 1 mL of normal saline. One hour after treatment, each animal received absolute ethanol (1ml / rat) orally by gavage. The other 30 mice were treated with oral ethanol after induction of gastric ulcer as described above, but all treatments were once a day for 14 days. At the end of both tests, ulcer index, histopathologic exams, Malonedialdehyde (MDA) and Superoxide dismutase (SOD) were measured.Results: Ethanolic extract of Satureja bachtiarica (400 mg/kg) and omeprazole had a significant effect on reducing ulcer index and increasing ulcer inhibition. It significantly preserved the gastric wall mucosa and reduced the formation of ethanol-induced gastric lesions. Also in this study a significant increase in superoxide dismutase (SOD) activity and a significant decrease in Malonedialdehyde (MDA) in gastric tissue were observed.Recommended applications/industries: The anti-ulcer effect of this plant seems to be due to the reduction of oxidative stress, which is probably due to the presence of thymol and carvacrol in the plant extract. This plant may be considered officially in the treatment and prevention of stomach ulcers in the future. پرونده مقاله

Sebaceous gland neoplasms are one of the cutaneous neoplasms in the canine. A 5-year-old ovary hysterectomy female, mixed breed terrier was referred to veterinary clinic of the Islamic Azad University, Shahrekord Branch due to a mass in the head area. The morphological characteristics of the lesion revealed an encapsulated, round, solitary yellowish-white mass, relatively soft consistency with an approximate diameter of 9 mm in the right midline the forehead and calvarium area with minor hair loss. Next, a complete excisional biopsy was done for pathology diagnosis. After dehydration, clearing and impregnated with paraffin, a tissue sample was stained with Hematoxylin and Eosin method. The microscopic characteristics of the tumor mass showed two different cell types, including mature sebaceous gland cells with vacuolated cytoplasm and small hyperchromic nucleus, and several rows of basaloid cells around sebaceous glands without mitotic division that were not adjacent to hair follicles. Inside several follicles, sections of the middle parts of demodex's body were observed. Our report is a unique example of sebaceous adenoma with infection of hair follicles with demodex mites in an ovariohysterectomy in a female dog. پرونده مقاله
