Pomegranate (Punica granatum L.) has been used widely in the traditional medicine of various civilizations for more than 5000 years. The pomegranate tree has several parts; each part has useful medicinal effects. Previous studies have demonstrated the antibacterial, antioxidant, and anti-inflammatory properties of pomegranate. The aim of the present study was to determine whether administration of pomegranate extract could result in morphometric changes in the kidneys of rats. Eighteen male rats (180-200 g) were divided into three groups that received either: G1, distilled water; G2, 250 mg kg-1 pomegranate extract; and G3, 500 mg kg-1 pomegranate extract via oral gavages daily for eight weeks. At the end of eight weeks, the rats were euthanized and their kidneys were removed and processed for morphometric analyses. In rats received pomegranate extract, the kidney weight, kidney weight/body weight ratio, cortex volume and glomerular volume were increased (p < 0.05), while, medulla volume and the number of glomeruli per kidney did not change. No pathological lesions were observed in the kidney. Therefore, pomegranate hydro-alcoholic extract at doses of 250 and 500 (mg kg-1) increased the volume of some parts of the kidney; however, it did not cause any pathological changes in the kidney.

Grape seed proanthocyanidin (GSP) bears a very powerful antioxidant effects. Studies demonstrated that proanthocyanidins protect against free radicals mediated cardiovascular and renal disorders. The present study was designed to assess the effect of GSP on the heart of diabetic rats. Forty rats were divided into four groups of 10 animals each: Group I: control, Group II: control group were given GSP, Group III: diabetic group, Group IV: diabetic group treated with GSP. Diabetes was induced by a single dose of streptozotocin, and then GSP (200 mg kg-1 body weight) was administrated for four weeks. Blood glucose, glycosylated hemoglobin (HbA1c) and also the levels of lipid peroxidation and antioxidant enzymes were examined in the heart tissues of all groups. Oral administration of GSP to diabetic rats significantly reduced (p < 0.05) heart weight, blood glucose, HbA1c and lipid peroxidation level, but increased (p < 0.05) body weight and activities antioxidant enzymes when compared to diabetic group. The results indicated that GSP could be useful for prevention or early treatment of cardiac disorder caused by diabetes.
