RESUMO

The aim of the study was to investigate if alcohol and disulfiram (DSF) individually and in combination affect bioelements' and red-ox homeostasis in testes of the exposed rats. The animals were divided into groups according to the duration of treatments (21 and/or 42 days): C21/C42 groups (controls); OL21 and OL22-42 groups (0.5 mL olive oil intake); A1-21 groups (3 mL 20% ethanol intake); DSF1-21 groups (178.5 mg DSF/kg/day intake); and A21+DSF22-42 groups (the DSF ingestion followed previous 21 days' treatment with alcohol). The measured parameters in testes included metals: zinc (Zn), copper (Cu), iron (Fe), magnesium (Mg) and selenium (Se); as well as oxidative stress (OS) parameters: superoxide anion radical (O2•-), glutathione reduced (GSH) and oxidized (GSSG), malondialdehyde (MDA), hydrogen peroxide (H2O2) decomposition and activities of total superoxide dismutase (tSOD), glutathione-S-transferase (GST) and glutathione reductase (GR). Metal status was changed in all experimental groups (Fe rose, Zn fell, while Cu increased in A21+DSF24-32 groups). Development of OS was demonstrated in A1-21 groups, but not in DSF1-21 groups. In A21+DSF22-42 groups, OS was partially reduced compared to A groups (A1-21>MDA>C; A1-21

RESUMO

Examination of cadmium (Cd) toxicity and disulfiram (DSF) effect on liver was focused on oxidative stress (OS), bioelements status, morphological and functional changes. Male Wistar rats were intraperitoneally treated with 1 mg CdCl2/kg BW/day; orally with 178.5 mg DSF/kg BW/day for 1, 3, 10 and 21 days; and co-exposed from 22nd to 42nd day. The co-exposure nearly restored previously suppressed total superoxide dismutase (SOD), catalase (CAT) and increased glutathione peroxidase (GPx) activities; increased previously reduced glutathione reductase (GR) and total glutathione-S-transferase (GST) activities; reduced previously increased superoxide anion radical (O2·-) and malondialdehyde (MDA) levels; increased zinc (Zn) and iron (Fe), and decreased copper (Cu) (yet above control value), while magnesium (Mg) was not affected; and decreased serum alanine aminotransferases (ALT) levels. Histopathological examination showed signs of inflammation process as previously demonstrated by exposure to Cd. Overall, we ascertained partial liver redox status improvement, compared with the formerly Cd-induced impact.

RESUMO

The objective of our study was to examine testicular toxicity of cadmium (Cd), focusing on oxidative stress (OS), essential metals and androgenic status and morphological changes. Male Wistar rats [controls and four Cd-subgroups (n = 6) organized according to the exposure (1, 3, 10 and 21 days)] were intraperitoneally (i.p.) treated with 1 mg CdCl2/kg/day. Testicular Cd deposition was noticed from the 1st day. After 10 and 21 days, copper (Cu) and iron (Fe) increased by 60-109% and 43-67%, respectively, while zinc (Zn) decreased by 24-33%. During 1-21 days of the exposure, decrease in testicular total superoxide dismutase (SOD) and total glutathione-s-transferase (GST) activities occurred gradually by 30-78% and 15-84%, respectively, while superoxide anion radical (O2(-)) increased gradually by 114-271%. After 10-21 days, decrease in testicular catalase (CAT) activity appeared by 13-31%. After 21 days, malondialdehyde (MDA) decreased by 44% and the ratio of oxidized glutathione/reduced glutathione (GSSG/GSH) increased by 130% in testes of the rats exposed to Cd. Additionally, decreased testicular testosterone level and the relative testes mass, along with induced microscopic and macroscopic changes were occured, what can be explained as the consequence of instantly developed OS, impaired essential metals status and Cd testicular deposition.

RESUMO

INTRODUCTION: Chickenpox is highly contagious childhood disease which occurs as a result of varicella-zoster virus primary infection. Symptomatic therapy is usually adequate for chickenpox, but in some cases it requires combinations of antiviral drugs and antibiotics. OBJECTIVES: To present our expirience with chickenpox therapy in children and adult patients. MATERIAL AND METHODS: Study included 120 randomly chosen patients, 60 adults and 60 children, with confirmed chickenpox infection, hospitalised at Clinic for infectious diseases in Sarajevo. Observed period was 1st January 2005. to 30th June 2011. We compared used therapy and outcome of disease. RESULTS: We had 333 patients with confirmed chickenpox in mentioned period. Male sex prevailed. Antiviral (acyclovir) therapy was initiated in 8(13.5%) adults and 16(27%) children. Most frequently used antibiotic was Co-Amoxiclav in a group of adults and Ceftriaxone in a group of children. DISCUSSION AND CONCLUSION: We use different terapeutical approaches to chickenpox according to the severity of the clinical picture and the existence of underlying diseases. Symptomatic treatment is indicated in all immunocompetent patients with no signs of complications. Use of corticosteroids remains open dillemma. Our therapeutical approcach followed by actual guidelines proved to be usefull. No death cases were recorded in these

RESUMO

INTRODUCTION: Staphylococcal sepsis is one of the most serious bacterial infections in the world, in most cases accompanied by metastatic foci in various organ systems. OBJECTIVE: analyze the metastatic foci patients suffering from staphylococcal sepsis. PATIENTS AND METHODS: we analyzed the patients treated for staphylococcal sepsis during the ten year period. RESULTS: 67 patients were included, of which 45 (67,2%) with the outpatient acquired infection and 22 (32.8%) hospital acquired. Male was present in higher percentage 58.2% and the average age of patients was 39 years. Meticillin-sensitive strains are present in 73.1% and resistant isolates in 26.9%. Chi square test of independence showed a dependence isolated pathogens in relation to the place of infection p = 0,003. From the total number of metastatic foci, 39 was in the lung, 32 in the skin and subcutaneous tissue, 24 in the abdomen, 15 in the bones and joints, 11 heart and brain 2. CONCLUSION: The greatest number of metastases was in the lung. Significantly large number of patients had outpatient infection with predominance of meticillin sensitive strains while in hospital infections in a greater percentage were meticillin rezistent strains. Proven dependence of isolated pathogens in relation to the place of infection (outpatient/hospital).

RESUMO

CONFLICT OF INTEREST: none declared. INTRODUCTION: Varicella or chickenpox is highly contagious, childhood infectious disease caused by primary infection with varicella - zoster virus from the herpes family of viruses. Usually it has a mild clinical course, rarely with described complication, mostly affecting respiratory tract and rarely the central nervous system. CASE REPORT: The case present 8 year old boy hospitalized eighth day of disease with clinical pictures of varicella complication. Upon receipt tachydyspnea, high fever, tachycardia, hypotensive with positive findings on lung auscultation in the sense of pneumonia. Extremely high values of non-specific inflammatory parameters are implied on bacterial infection which is treated using triple antimicrobial therapy and antiviral. A detailed clinical, laboratory and radiological evaluation is determined of clinical disease complication under a picture of MODS that required prolonged multidisciplinary treatment in ICU. CONCLUSION: The disease had a favorable clinical outcome in terms of training completely without consequences but, with the detected congenital absence lower lobe of right lung and transposition of the brachiocephalic trunk.
