Purpose. To investigate the effect of EPO administration on postresuscitation renal function.Methods. Twenty-four female Landrace/Large-White piglets aged 10–15 weeks with average weight of19±2 kg were randomly assigned to 2 different groups of 12 subjects each. After the end of an 8-minute ventricular fibrillation, the control group (Group C) received saline as placebo, whereas the EPO group (Group E) received EPO 5000 U/kg. The animals were resuscitated according to the 2010 European Resuscitation Council Guidelines for Resuscitation.Results. Five animals (41.67%) from Group C and 11 animals (91.67%) from Group E achieved ROSC (p=0.027). Eight animals (66.67%, 5 surviving and 3 nonsurviving) from Group C suffered severe kidney damage or AKI compared to animals from Group E, in which none of the swine had evidence of severe kidney damage or AKI (p=0.001). There was a statistically significant difference in all tested biochemical markers between the two groups, as well as a positive correlation of creatinine with NGAL, L-FABP, and IL-18 (summed mean values’p=0.049, 0.01, and 0.004, resp.).Conclusions. Administration of EPO protected swine from postresuscitation acute kidney injury.

Aim.To evaluate the effects of erythropoietin administration on the adrenal glands in a swine model of ventricular fibrillation and resuscitation.Methods. Ventricular fibrillation was inducedviapacing wire forwarded into the right ventricle in 20 female Landrace/Large White pigs, allocated into 2 groups: experimental group treated with bolus dose of erythropoietin (EPO) and control group which received normal saline. Cardiopulmonary resuscitation (CPR) was performed immediately after drug administrationas perthe 2010 European Resuscitation Council (ERC) guidelines for Advanced Life Support (ALS) until return of spontaneous circulation (ROSC) or death. Animals who achieved ROSC were monitored, mechanically ventilated, extubated, observed, and euthanized. At necroscopy, adrenal glands samples were formalin-fixed, paraffin-embedded, and routinely processed. Sections were stained with hematoxylin-eosin.Results.Oedema and apoptosis were the most frequent histological changes and were detected in all animals in the adrenal cortex and in the medulla. Mild and focal endothelial lesions were also detected. A marked interindividual variability in the degree of the intensity of apoptosis and oedema at cortical and medullary level was observed within groups. Comparing the two groups, higher levels of pathological changes were detected in the control group. No significant difference between the two groups was observed regarding the endothelial changes.Conclusions. In animals exposed to ventricular fibrillation, EPO treatment has protective effects on the adrenal gland.

AbstractIntroductionThe American Heart Association (AHA; Dallas, Texas USA) and European Resuscitation Council (Niel, Belgium) cardiac arrest (CA) guidelines recommend the intraosseous (IO) route when intravenous (IV) access cannot be obtained. Vasopressin has been used as an alternative to epinephrine to treat ventricular fibrillation (VF).Hypothesis/ProblemLimited data exist on the pharmacokinetics and resuscitative effects of vasopressin administered by the humeral IO (HIO) route for treatment of VF. The purpose of this study was to evaluate the effects of HIO and IV vasopressin, on the occurrence, odds, and time of return of spontaneous circulation (ROSC) and pharmacokinetic measures in a swine model of VF.MethodsTwenty-seven Yorkshire-cross swine (60 to 80 kg) were assigned randomly to three groups: HIO (n=9), IV (n=9), and a control group (n=9). Ventricular fibrillation was induced and untreated for two minutes. Chest compressions began at two minutes post-arrest and vasopressin (40 U) administered at four minutes post-arrest. Serial blood specimens were collected for four minutes, then the swine were resuscitated until ROSC or 29 post-arrest minutes elapsed.ResultsFisher’s Exact test determined ROSC was significantly higher in the HIO 5/7 (71.5%) and IV 8/11 (72.7%) groups compared to the control 0/9 (0.0%; P=.001). Odds ratios of ROSC indicated no significant difference between the treatment groups (P=.68) but significant differences between the HIO and control, and the IV and control groups (P=.03 and .01, respectively). Analysis of Variance (ANOVA) indicated the mean time to ROSC for HIO and IV was 621.20 seconds (SD=204.21 seconds) and 554.50 seconds (SD=213.96 seconds), respectively, with no significant difference between the groups (U=11; P=.22). Multivariate Analysis of Variance (MANOVA) revealed the maximum plasma concentration (Cmax) and time to maximum concentration (Tmax) of vasopressin in the HIO and IV groups was 71753.9 pg/mL (SD=26744.58 pg/mL) and 61853.7 pg/mL (SD=22745.04 pg/mL); 111.42 seconds (SD=51.3 seconds) and 114.55 seconds (SD=55.02 seconds), respectively. Repeated measures ANOVA indicated no significant difference in plasma vasopressin concentrations between the treatment groups over four minutes (P=.48).ConclusionsThe HIO route delivered vasopressin effectively in a swine model of VF. Occurrence, time, and odds of ROSC, as well as pharmacokinetic measurements of HIO vasopressin, were comparable to IV.BurgertJM, JohnsonAD, Garcia-BlancoJ, FultonLV, LoughrenMJ.

Background: Multiple myeloma (MM) is a disease of B cell population with excessive secretion of immunoglobulins and presence of free light chains (FLCs) that are by products of immunoglobulin synthesis. Free light chains play crucial role in causing renal damage. Interleukine-6 (IL-6) supports the survival and/or expansion of MM cells by stimulating cells as well as by preventing programmed cell death. Aims and Objectives: The aim of this study was to evaluate serum and urine free light chains (FLC)measurement and compare with IL-6 levels in patients with different stages of Multiple Myeloma (MM) and control group of subjects and to determine their relevance in acute kidney injury occurrence. Materials and Methods: Recruitment of patients with MM (n=62) made the hematologist that followed clinical Solomon-Durie MM classification. Control group consisted of 20 healthy individuals. Results: Patients with MM and renal function injury had significantly higher concentration of urine κ chains compared to control group and group of MM without renal function injury (p<0.005), whereas this difference was not observed when the patients were divided into disease stages groups. Concentration of IL-6 was significantly higher in patients at MM steady stage compared to control group (p<0.001) and significant difference was also detected in patients with MM at relapse stage and control group (p<0.0005). Concentration of IL-6 in MM patients without renal function and with renal function injury was significantly higher compared to control group (p< 0.001; p<0.0005 respectively). Statistically significant correlation was determined between sera κ and urine κ chains (rho=0.437; p<0.01) as well as between urine λ and sera λ chains (rho=0.505; p<0.01) and between urine κ and urine λ chains (rho=0.364; p<0.01). Conclusion: Results showed that urine κ chains, sera κ chains and IL-6 are constructing a fine tuned net and point to conclusion that FLC and IL-6 are important for an early treatment response detection for patients with potentially reversible renal failure.

Objectives The aim of this study was to investigate and compare the severity of kidney damage following lower limb ischemia–reperfusion and direct kidney ischemia–reperfusion. Methods Thirty Sprague Dawley male rats were randomly divided into three groups; lower extremity ischemia–reperfusion group (Group 2), renal ischemia–reperfusion group (Group 3) and control (anesthesia and median laparotomy only) (Group 1). In group 3, 1-h ischemia was performed on the kidney and in group 2, 1-h ischemia was performed on the left lower extremity. This procedure was followed by reperfusion for 24 h. Renal tissues were removed after the reperfusion period and the groups were evaluated for glutathioneperoxidase activity, malondialdehyde and GSH levels, and furthermore, their histolopathological scores were calculated. Results Renal malondialdehyde levels were significantly higher in Group 2 and Group 3 than they were in the Control group. There was no significant difference in renal malondialdehyde levels between Group 2 and Group 3. Kidney glutathione (GSH) levels were statistically lower in Group 2 and Group 3 than in the Control group. No statistically significant difference was found between Group 2 and Group 3 regarding their GSH levels. In histological evaluation, there was no statistically significant difference between Group 2 and Group 3 in terms of kidney damage score. Conclusions This study has identified that lower extremity ischemia induces remote kidney damage with similar features to kidney injury, occurring after direct kidney ischemia–reperfusion.

Background: Health problem are culturally associated with smoking in developing countries. Many hazardous chemicals are taken up by direct or passive smoking causing lipid peroxidation resulting in oxidative stress. Objectives: To estimate the occurrence of smoking and its effects on the lipid profile in populations of Hasilpur, Pakistan. Methodology: The current study was conducted from April - August 2014. Out of 247 apparently healthy subjects of both genders (male=220; female=27), 134 were smokers and 113 were non-smokers. In order to analyze lipid profile, blood samples were collected in early morning hours from the selected members who were asked to fast all night. By using Chem-100 chemistry analyzer, cholesterol, triglyceride, HDL, LDL and VLDL were analyzed. Results: The overall prevalence of smokers was 54.25%. The results showed 60.9% prevalence in males and 0% in females. The mean value of serum triglyceride in control, light smokers and heavy smokers was 147.4±11.7mg/dl, 190.8±41.4 and 205.3±29.7mg/dl, respectively. The results of cholesterol in control, light smokers and heavy smokers were 147.38±7.99mg/dl, 136.8 ±12. 8mg/dl and 173.44±8.63mg/dl, respectively. There was a considerable distinction in the mean level of serum triglyceride and cholesterol between the control group, light smokers and heavy smoker groups (P<00.5). The mean value of HDL of control, light smokers and heavy smokers was 30.93±1.30mg/dl, 31.10±2.45 and 34.58±1.55mg/dl, respectively. The mean values of LDL and VLDL of control, light smokers and heavy smokers were 110.46±3.63mg/dl, 106.00±4.52mg/dl, 117.19±3.48mg/dl and 33.54±3.11mg/dl, 49±9.02mg/dl, 41.06±5.34mg/dl, respectively. There was significant difference in the mean level of HDL, LDL and VLDL between the control group, light smokers and heavy smoker groups (P<0.05). Conclusion: This study concluded that smoking is the reasons of variation in the lipid profile. Elevated period of smoking and the number of smoked cigarettes/day reason the alteration in serum lipid levels and is probably related with increased danger for coronary artery disease.

This study aimed to evaluate the effects of nano mineral-supplemented diet on sow productivity. The data were estimated by several parameters consisting of piglet live ratio at newborn stage and weaning stage, piglet weight at newborn stage and weaning stage, metal content in piglet livers. The results showed that live ratio of newborn piglets in group III was highest (93.44 ± 2.83%) comparing with other groups. However, there was no significant difference of live ratio in piglets at weaning stage between nano mineral-supplemented groups with control. The birth weight of piglets in nano mineral-supplemented groups was similar to control group. The birth weight of piglets in nano mineral-supplemented groups was ranged from 1,361.61 ± 47.37 grams (group II) to 1,410.48 ± 44.28 grams (group I). However, the average weight of weaned pigs in groups III and IV was higher than other groups (6,772.92 ± 105.47 grams and 6,818.87 ± 89.59 grams). Moreover, the amount of Fe, Cu, Zn, Mn in piglet liver from nano mineral-supplemented groups have been found to be lower than those in control group. These results revealed that the supplement of nano minerals for sows promoted the reproductive performance of sows and reduced mineral content in the liver of piglets.

A commercially prepared lean meat was fed to young infants as a supplement to a diet already adequate in all food factors. In those infants first fed meat under 2 months of age, there was improvement in physical growth as determined by weight and height measurements. The same group demonstrated an improvement in hemoglobin levels; the elimination of the physiologic drop in total protein levels of the serum, with a prompt sustained rise in values, the greater part of which was composed of the globulin fraction. In those infants first fed meat after 2 months of age, there was a slight improvement in average weight gain, but no significant difference was noted in other body measurements, total protein, albumin or globulin fractions, or hemoglobin levels. Illness rates for the two years of the study demonstrated a 40% lower morbidity rate in the meat-fed group as compared to the control group. In striving for the optimum in infant nutrition protein requirements should be evaluated both quantitatively and qualitatively.
