5-fluorouracil (5-FU) is a potent antineoplastic agent used for the treatment of various malignancies. The L-arginine nitric oxide (NO) pathway involved in the pathogenesis of chemotherapy induced kidney damage. This work investigated the beneficial mechanism of L-arginine supplementation in 5-FU induced nephropathy. Eighty male Wistar rats were divided into four equal groups: control group; L-arginine group (378 mg/rat/day for 4 weeks); 5-FU group (189 mg/rat/week for 4 weeks) and L-arginine for 1 week before and 4 weeks concomitant with 5-FU group. At the end of experiment, the kidney functions were assessed and kidneys specimens were processed for paraffin sections and stained with haematoxylin and eosin (H&E), Masson’s trichome (MT) and periodic acid-Schiff (PAS) stains. Other sections were processed for immunohistochemical demonstration of caspase-3 and inducible NO synthase (iNOS). Image analyser was used to analyse the results morphometrically and statistically. L-arginine administration to 5-FU treated animals elicited significant reduction in serum urea and creatinine levels, urine volume, urinary protein excretion and kidney/body weight ratio in comparison to fluorouracil treated group. L-arginine improved glomeruloscelerosis, degeneration of convoluted tubules and interstitial fibrosis in 5-FU treated animals. L-arginine attenuated effectively some biochemical and histological changes in 5-FU nephrotoxicity. (Folia Morphol 2017; 76, 4: 608–619)
Background: The current study aimed to elucidate the protective role of combined fenugreek and α-tocopherol against cadmium induced histopathological changes in the testes. Materials and methods: Thirty adult male albino rats divided into three equal groups 10 rats each. Group I is the control group. Group II received 5 mg/kg/ day cadmium chloride. Group III received 5 mg/kg/day cadmium chloride and 150 mg/kg/day fenugreek and 100 mg/kg/day of α-tocopherol. The treatment of all groups was done by oral gavage for 60 consecutive days. The testes were removed and subjected to histopathological and ultrastructure study. Results: Rats exposed to cadmium showed severe histopathological changes in the testicular spermatogenic series, many vacuoles and multinucleated giant cells. Treatment with fenugreek and α-tocopherol partially improved the morphological changes, reduced tissue damage and rebuilt of the spermatogonia layer. Conclusions: Fenugreek and α-tocopherol might represent a promising medicinal combination to ameliorate the toxic effects of cadmium exposure. (Folia Morphol 2015; 74, 3: 325–334)
Background: Knowledge of the anatomical variations of the profunda femoris artery and its circumflex branches is important during angiographic diagnostic procedures as well as during performing surgery in the femoral region. The aim of this study was to examine the original sites, distances and variations of the profunda femoris artery and its circumflex branches. Materials and methods: The study was conducted in the Department of Anatomy, Faculty of Medicine, King Abdulaziz University from October, 2011 to May, 2013 after the approval of the medical ethical committee. Dissections of 90 femoral triangles of 25 male and 20 female adult human cadavers were performed to demonstrate the origin and distribution of the profunda femoris artery and its circumflex branches. Results: The profunda femoris artery mostly originated from the posterolateral aspect of the femoral artery in 42% of male limbs and in 42.5% of female limbs, from the posterior side in 24% of male and 27.5% of female limbs, from the lateral side in 20% of males and female limbs and from the posteromedial aspect in 14% of male limbs and in 7.5% of female limbs. The mean distance of origin of profunda femoris artery from the midpoint of inguinal ligament was 51.5 ± 1.9 mm in right male, 49.7 ± 1.9 mm in left male, 48.5 ± 2.2 mm in right female and 48.9 ± 2.2 mm in left female limbs. The medial and lateral circumflex arteries originated mostly from the profunda femoris artery (60% in males; 57.7% in females) at a mean distance of 18.6 ± 2.1 mm and 20.2 ± 2.2 mm in right male, 19.6 ± 1.9 mm and 22.5 ± 2.3 mm in left male, 18.8 ± 2.7 mm and 21 ± 2.6 mm in right female and 19.1 ± 2.1 mm and 21.7 ± 2.6 mm in left female limbs, respectively. The original incidence of the medial and lateral circumflex femoral arteries from the femoral artery including the common trunk was 40% in male and 42.3% in female limbs. Conclusions: Awareness of the original sites and distances of the profunda femoris artery and its circumflex femoral branches will allow the surgeon to define the vascular pattern before performing any invasive procedure and to avoid unexpected iatrogenic injuries.
