Amelioration of aluminium-induced liver damage by vitamin E

Objective: To investigate the effects of aluminium sulphate on the microscopic morphology of the liver and on vitamin E amelioration of aluminium-induced liver damage. Methods: Rats were injected intraperitonally with aluminium sulphate alone or aluminium sulphate together with vitamin E, with saline injected rats used as the control group. The study took place in Pamukkale University Faculty of Medicine in 2005. Results: The rats exposed to aluminium showed morphological changes in addition to previously reported biochemical changes in the liver. Ihe anti-oxidant vitamin E significantly diminished the liver damage seen due to aluminium. Conclusion: There is an apparent protective effect of vitamin E on parenteral aluminium exposure

Doğum öncesi dönemde böbrek gelişiminde E-Cadherin ekspresyonunun immunohistokimyasal olarak gösterilmesi

Objective: Cadherins are a protein family of Ca2+ dependent transmembrane cell adhesion molecules that play a key role in the regulation of organ and tissue development during embriyogenesis. We aimed to show E-cadherin expression immunohistochemically in the pre-natal period in the development of kidney. Materials and Methods: In this study, 45 fetuses were obtained from 12 female and 4 male adult Wistar rats bred in Pamukkale University Experimental Research Unit. Fetuses were removed from 11, 13, 15, 17 and 19. day pregnant rats. After routine light microscopy technique, fetuses fixed in 10% formaldehyde were embedded in paraffin. Serial 5 μ thick sections from parafin blocks were taken to slides and the immunohistochemistry method, was applied to determine the E-cadherin expression. Results: In this study, E-cadherin showed negative expression in E11 and 13 days kidney tissues. In the 15, 17 and 19. day kidneys, E-cadherin expression was positive. Tubule structures were more darkly stained than glomerular structures. In lateterm fetal kidneys, E-cadherin expression was gradually diminished in the renal corpuscle. Conclusion: We determined that E-cadherin expression showed differences both in different developmental stages and different areas of kidney. These differences may be important in terms of the investigation of etiologies and diagnosis of congenital kidney diseases and in the evaluation of nephrotoxicity and kidney pathologies. © 2013 by Erciyes University School of Medicine

Transmission electron microscopy study of the effects of cadmium and copper on fetal rat liver tissue

During the entire period of their pregnancies, three groups of adult pregnant Wistar albino rats were provided with tap water (control; group I) or with tap water containing 10 mg/kg CdCl2 (group II) or 10 mg/kg CdCl2 plus 10 mg/kg CuSO4 (group III). At term, the animals were sacrificed and the fetal livers were removed and examined under electron microscopy. The liver tissue of the fetuses in maternal groups II and III showed degenerative changes to their hepatocytes. In group II, the smooth endoplasmic reticulum tubules showed dilatation, and the mitochondria showed a dense matrix. In group III, some mitochondrial degeneration was also seen, with a diluted matrix and mitochondrial dilatation. There were also more heterochromatic nuclei and an increased number of ribosomes. None of these histopathological changes were present in the fetal liver samples from the maternal group I control animals. © Copyright 2007 by Humana Press Inc.

The effect of medroxyprogesterone acetate on bone marrow and testis during cytotoxic chemotherapy

The effect of medroxyprogesterone acetate (MPA) on the mitotic activity of bone marrow and testis during chemotherapy was investigated experimentally in an animal study. A total of 120 male Swiss albino mice were included in this study. Six groups were formed, each consisting of 20 mice. Low-dose MPA (LD-MPA) (15 mg/kg), high-dose MPA (HD-MPA) (100 mg/kg), LD-MPA plus cyclophosphamide (CP) (65 mg/kg), HD-MPA plus CP (65 mg/kg), and CP (65 mg/kg) were administered to the test groups and no drug was administered to the control group. Bone marrow samples and testis were examined for mitotic activity rate (MAR) on days 0, 18, 22, 26, and 30. In groups with regimens containing CP, MAR of hematopoietic cells in bone marrow was suppressed significantly (p 0.05). Mitotic activity rate of the testis cells was significantly suppressed in groups with regimens containing MPA (p <0.05). In conclusion, MPA inhibited mitotic activity of testis, but there was no effect on the mitotic activity of bone marrow. These data do not seem to confirm the hypothesis of a myeloprotective effect of MPA

Clinical Features and Etiology of Adult Patients with Fever and Rash

Background: Patients with fever and rash often pose an urgent diagnostic and therapeutic dilemma for the clinician. The nonspecificity of many fever and rash syndromes mandates a systemic approach to diagnosis. Objective: We aimed to determine the etiology of fever and rash in 100 adult patients followed-up as in- or outpatients prospectively. Methods: All the patients, who presented with rash and fever, were followed-up prospectively and their clinical and laboratory studies were evaluated. Results: The median age was 35 years (14 similar to 79 years); 45 were female and 55 were male. Patients were divided into 3 groups according to the etiology: infectious (50%), noninfectious (40%) and undiagnosed (10%). The most common type of rash was maculopapular, and the most common 5 causes were measles, cutaneous drug reactions, varicella, adult-onset Still's disease (ASD) and rickettsial disease. Viral diseases among infectious causes and cutaneous drug reactions, among the noninfectious causes, were determined as the main diseases. The mortality rate was 5% and the reasons of mortality were as follows: toxic epidermal necrolysis (2 patients), ASD (1), staphylococcal toxic shock syndrome (1) and graft-versus-host disease (1). Conclusion: Adult patients with fever and rash had a wide differential diagnosis. The most common type of rash was determined as maculopapular, and the most frequent five diseases were measles, drug reactions, chickenpox, ASD and rickettsial infection. Viral diseases among infectious causes and drug reactions among noninfectious causes were determined as the leading etiologies. (Ann Dermatol 24(4) 420 similar to 425, 2012
