Absence of Middle Hepatic Vein Combined with Retro-Aortic Left Renal Vein: a Very Rare Case Report

The hepatic and renal veins drain into the inferior vena cava. The upper group of hepatic veins consists of three veins which extend to the posterior face of the liver to join the inferior cava. The left renal vein passes anterior to the aorta just below the origin of the superior mesenteric artery. We detected a variation in the hepatic and renal veins in a multislice CT angiogram of a nine-year-old male patient in the Radiology Department of Afyon Kocatepe University Medical School. The upper group hepatic veins normally drains into the inferior vena cava as three separate trunks, namely the right, left and middle. In our case, we found that only the right and left hepatic veins existed and the middle hepatic vein was absent. Furthermore, the left renal vein, which normally passes anterior to the abdominal aorta, was retro-aortic. Left renal vein variations are of great importance in planning retroperitoneal surgery and vascular interventions. Knowledge of a patient's hepatic vein and renovascular anatomy and determining their variations and anomalies are of critical importance to abdominal operations, transplantations and preoperative evaluation of endovascular interventions

The effect of ozone on blood pressure in DOCA-salt-induced hypertensive rats

Background: Hypertension is a risk factor for the cardiovascular diseases. Ozone as a therapeutic agent for the treatment of several disorders. We aimed to observe the effects of ozone on the blood pressure in DOCA-salt hypertensive rats. Methods: Twenty three young Sprague Dawley male rats were divided into three groups; Control (C), Hypertension (H) and Hypertension + Ozone (HO). Hypertension was induced by injection of DOCA-salt (25 mg/kg, s. c.) twice weekly, 4 weeks, whereas intraperitoneal ozone was administered (1.1 mg/kg) for 10 days. Serum endothelin-1, nitric oxide and renin levels were measured with ELISA. Blood pressures were monitored using a tail cuff system. Endothelin-1, ET receptor A and ET receptor B mRNA expression in heart and vascular tissue were assessed by quantitative reverse transcription polymerase chain reaction. Results: Blood pressure, serum endothelin-1 and ET receptor A mRNA expression levels were increased in H group, whereas serum renin, nitric oxide and ET receptor B mRNA expression levels in the heart and vascular tissue decreased compared with C and HO groups, which were counteracted by ozone treatment. Conclusion: Ozone treatment decreases blood pressure and is effective in preventing the progression of hypertensive disease, the mechanisms of which are associated with anti-vasoconstrictor effects through reducing the levels of serum endothelin-1 and ET receptor A mRNA expression in the heart and vascular tissue

Assessment of pulmonary functions and anthropometric measurements in women with polycystic ovary syndrome

Objectives. The aims of this study were to compare pulmonary function tests of patients with polycystic ovary syndrome (PCOS) versus healthy women, and to investigate correlations between pulmonary function tests and anthropometric measurements of them

Protective Effect of Alpha Lipoic Acid on Rat Sciatic Nerve Ischemia Reperfusion Damage

Background: Alpha lipoic acid is a potent antioxidant that plays numerous roles in human health. This study examined the effect of ALA on rat sciatic nerve ischemia reperfusion damage
