A 9-year-old spayed female Terrier dog was evaluated for lethargy, anorexia, polyuria, polydipsia and dysuria. The dog had been diagnosed with diabetes mellitus about 6 months ago and received subcutaneous doses of insulin. The patient showed insulin resistance and severe persistent fasting hyperglycemia in the face of high-dose insulin treatment, hyper-cholesterolemia and urinary tract infection. After a complete evaluation, the dog was diagnosed with a polycystic ovary and a cystic uterine remnant during an exploratory celiotomy. The polycystic ovary and cystic uterine remnant were removed and submitted for histopathological evaluation. Two weeks after surgery the blood glucose level and one month later serum cholesterol level were controlled, using a low level of insulin therapy (0.25 IU kg-1 Neutral Protamine Hagedorn (NPH) insulin, every 12 hr). In the present study, the clinical and laboratory results showed that ovarian remnant syndrome as an infrequently encountered condition in dog was related to some metabolic disorders such as insulin resistance, uncontrolled hyperglycemia, dyslipidemia and also recurrence urinary tract infection. To the best of authors’ knowledge, no reports of hypercholesterolemia in dog have been made before as a complication of ovarian remnant syndrome.

Cynodon dactylon (Bermuda grass) is a perennial plant traditionally used as an herbal medicine in many countries. In the present study, anti-atherosclerotic property of ethanolic extract of C. dactylon was investigated in the experimentally induced hypercholesterolemia in rats. In this study, 36 male Wistar rats were selected and allocated into six groups (n = 6). The control group received a normal diet, sham group received a high cholesterol diet (HCD; 1.50% cholesterol and 24.00% fat) and other groups received a HCD and ethanolic extract of C. dactylon at low (100 mg kg-1), moderate (200 mg kg-1) and maximum (400 mg kg-1) doses via gavages. The last group received atorvastatin (10 mg kg-1) through gavage with a HCD. The study period for all groups was six months. At the end of this period, parameters including total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were assessed in the blood samples. Additionally, histopathological and immunohistochemical examinations on coronary and aorta arteries sections were performed. The results showed an increase in vessels wall thickness and proliferation of smooth muscle cells in the HCD group, while these pathological changes were not seen in C. dactylon-treated groups. Treatment of HCD animals with C. dactylon positively changed lipid profile by lowering of TC, TG and LDL-C. The results indicate that C. dactylon prevents from early atherosclerotic changes in the vessels wall.
