Ureteral obstruction may result in permanent kidney damage. Research suggests that the Indonesian Propolis Extract (IPE) play a strong role on free oxygen radicals removal and prevents oxidative stress. This study aims to investigate the efficacy of IPE on malondialdehyde (MDA) reduction and systolic blood pressure (SBP) level down-regulationafter unilateral ureteral obstruction (UUO).A total of 32 rats were divided into four groups. Group 1 as control, Group 2 were rats with UUO, Group 3 were rats with UUO that were given IPE (oral 50 mg kg-1body weight) and Group 4 were rats with UUO that were given IPE (oral 100 mgkg-1 body weight). SBP level were measured once every week within duration of experiment and at day30 blood sample were taken for Malondialdehyde analysis. Statistical analysis was performed by one-way analysis of variance. There were statistically significant increase in MDA and blood pressure in Group 2, while there were significant decrease for MDA and blood pressure in Group 3 and 4 (p less than 0.001). In this experiment we suggest that IPE prevents kidney damage by decreasing oxidative stress (MDA) and SBP.

Objectives: We aimed to evaluate the effectiveness of sesamol in preventing the progressive renal damage caused by complete unilateral ureter obstruction (CUUO). Methods: Twenty four Wistar rats were separated into three groups: In the group 1 rats (the sham-control, n = 8), the ureters were exposed and manipulated, but not ligated. In the group 2 rats (CUUO-untreated, n=8), CUOO was accomplished by double-ligating the left ureter using 5-0 silk ties. In the group 3 rats (CUUO -Sesamol treated, n=8), CUOO was created as in the Group 2 rats, also given sesamol daily, commencing on the day of CUUO surgery. The rats’ left kidneys were examined histologically and biochemically within the 8th day Results: Histopathological total score, apoptotic index and MDA values in the group 2 show a significant increase when compared to the group 1. These values were significantly decreased in the group 3 rats when compared to the group 2 rats. Tissue GPx value in the group 2 show a significant decrease when compared to Sham-control group. However, these values were significantly increased in the group 3 rats when compared to the rats 2. Polymorph nuclear leukocyte infiltration in peritubular areas was observed in group II, with moderate interstitial fibrosis and tubular dilatation. Despite the presence of dilated tubule structures in group III, this group showed less bleeding, leukocyte infiltration, and fibrosis than group II. Conclusion: The results of this study have shown that CUOO-induced renal damage can be reduced using sesamol, possibly due to its antioxidant properties. The mechanism by which sesamol causes these effects merits further investigation. Keywords: Complete unilateral ureteral obstruction, renal damage, sesamol, oxidative stress, rat.

Our aim was to evaluate effect of etanercept on oxidative stress parameters in rats with experimental peritonitis and investigate the availability of etanercept usage in the treatment of peritonitis in the future. Twenty-eight rats were divided into four groups as control (group 1), peritonitis (group 2), peritonitis + cefazolin sodium (group 3), and peritonitis + cefazolin sodium + etanercept (group 4). Peritoneal tissue and blood samples were taken from all of the rats for histopathological and biochemical examination. The oxidative stress parameters were examined in blood and tissue samples. It was observed that rats with peritonitis benefit from cefazolin sodium treatment. Evaluating the effectiveness of etanercept was our main objective for this study. In this perspective, we compared group 3 and group 4 and found statistically significant decreases in oxidative parameters and statistically significant increases in antioxidants in serum and tissue samples in group 4. It is observed that there was a significant contribution of etanercept on biochemical and also histopathological results. As a result, the TNF-αinhibitor, etanercept, in addition to antibiotics given in the early treatment of peritonitis results in more significant improvement of histopathological and oxidative parameters as compared to antibiotics alone.

Background: Calcium hydroxide is a dental material used as a gold standard for pulp capping materials. However, calcium hydroxide has several weaknesses which cause many researchers to look for alternative ingredients that come from nature. Propolis in the field of dentistry has long been used because of its ability as an anti-inflammatory, anti-microbial, anti-fungal, and can cure scars. The combination of calcium hydroxide and propolis is proven to have good biocompatibility and anti-bacterial properties. One of the requirements of pulp capping material is to have sufficient compressive strength. Therefore, a research to test the compressive strength value of the combination of calcium hydroxide with propolis is needed. Purpose: To find out the difference in compressive strength of the combination of calcium hydroxide-propolis with a ratio of 1: 1, 1: 1.5, and 1: 2. Methods: The study used 4 treatment groups with each group consisting of 6 replications. Group 1 is a combination of calcium hydroxide-propolis with a ratio of 1: 1, group 2 with a ratio of 1: 1.5, group 3 with a ratio of 1: 2, and a positive control group using calcium hydroxide - sterile aquadest. Calcium hydroxide powder and propolis extract liquid is mixed according to comparison and printed on a cylindrical mold with the size of 4 mm x 6 mm. Then, the compressive strength was tested using an Autograph test instrument. Result: Compressive strength was smaller in group 3 compared to group 2, group 2 compared to group 1, and group 1 compared to the control group. Conclusion: In calcium hydroxide-propolis combination, the more propolis extract used in the combination the lower the compressive strength of the combination will be.

Background: Nerium oleander (NO) distillate is used to either protect heart cells against oxidative stress or reduce the risk of cardiovascular disease by regulating the production of reactive oxygen species. Hypoxia-inducible factors (HIFs) regulate cellular antioxidant defense mechanisms under hypoxic conditions in which heart cells survive; however, the key responsible mechanism of NO distillate for cardioprotection remains elusive. The objective of this study was to evaluate the effects on heart tissue at different time intervals after administering NO distillateintraperitoneally (IP) while considering the transcriptional regulation of HIFs and representative antioxidant enzymes.Materials, Methods & Results: The NO plant was chopped, and distillated water was added. The mixture was distilled, and the distillate separated and collected into tubes, after which it was lyophilized to obtain dry material. Twenty male Wistar albino rats (2-3 month-old, 250-300 geach) were used in the study. The rats were randomly divided into four groups. The control group (n = 5) received IP injections of saline; the remaining 15 rats received IP injections of a single dose of 7.5 mL NO distillate. The NO distillate injected rats were divided into three groupsaccording to the time from injection to harvest the heart tissue samples. The tissues were collected at 0 h (control; n = 5), 2 h (group 2; n = 5), 4 h (group 3; n = 5), and 8 h (group 4; n = 5) after injection and under general anesthesia (60 mg/kg ketamine, IP + 10 mg/kg xylazine, IP).Quantitative polymerase chain reaction (qPCR) was used to assess the expression profiles of the genes of interest in the heart tissues. Hypoxanthine phosphoribosyltransferase was used as the reference gene. The expression of manganese superoxide dismutase (MnSOD) mRNA was in a steady state level between the control group and group 2 (P > 0.05); however, it significantly increased in group 3 and 4 compared with that in the control (P < 0.05). Expression of catalase (CAT) mRNA was significantly higher in group 2 than in the control group (P < 0.05) although it was lower in group 3 and 4 than in group 2 (P < 0.05); however, it appeared to be similar among the control group, group 3, and group 4 (P > 0.05). Copper (Cu) SOD mRNA was equallyexpressed in both the control group and group 2 (P > 0.05) but was lower in group 3 and 4 than in group 2 (P < 0.05). Expressions of HIF1A, HIF2A, and HIF3A mRNA were detected in the rat heart tissues in the control and 2, 4, and 8 h after administration of NO distillate. Expression ofHIF1A mRNA was in a steady state and did not differ among groups 2, 3, and 4 (P > 0.05). Similarly, the expression of HIF2A mRNA did not change between the control group and group 2 (P > 0.05); however, it was higher in group 3 than in the control (P < 0.05) and tended to behigher in group 3 than in group 2 (P = 0.063). HIF3A mRNA expression did not change significantly in the heart tissue of any of the groups (P > 0.05).Discussion: The present study using rats determined that MnSOD, CAT, CuSOD, HIF1A, HIF2A, and HIF3A mRNA are expressed in the heart tissues after administration of NO distillate. The increased expression of HIF2A mRNA after 4 h in accordance with a rise in CAT mRNA after 2 h, and MnSOD mRNA after 4 and 8 h might confirm the role of HIF2A mRNA in oxidative stress defense by regulating antioxidant enzymes; consequently, this study may expand our understanding of uses of NO distillate with respect to molecular pathways.

In this study, the effect of free oxygen radicals on lipid peroxidation and the antioxidant role of α-tocopherol (vitamin E) in these reactions were investigated in haematoma fluid and venous blood samples in rabbits with femoral fracture. There were 21 male rabbits, divided into 3 groups. Conjugated dienes values (as optical density) were compared in venous blood of the rabbits in Group I taken preanaesthesia and after the onset of anaesthesia and the difference between these values proved to be insignificant ( P > 0.05). A control group (Group 2) was given saline before fracture occurrence and the other group (Group 3) was injected with α-tocopherol 20 mg/kg intramuscularly. Venous blood samples and fracture haematoma fluids in both Group 2 and Group 3 were assayed biochemically. It was established that conjugated dienes values in fracture haematoma fluid in rabbits in the control group were higher than the values in the venous blood of the rabbits in the same group (P < 0.05). However, conjugated dienes values in the a-tocopherol injected group both in the haematoma fluid and in venous blood were reduced compared with those in the control group ( P < 0.5). In view of the fact that ischaemia and reperfusion develop in fractured regions and that general body ischaemia develops following serious fractures of the extremities, we consider that prophylactic administration of antioxidants such as α-tocopherol may be beneficial in suppressing the destructive effects of free oxygen radicals in cells.

Objective: Obstruction of the urinary tract has marked effects on renal blood flow, glomerular filtration rate (GFR), and tubular function. Ureteral obstruction results in an injury response that can progress to irreversible renal fibrosis and tubular damage by apoptosis. Materials and Methods: Forty five rabbits aged 13-17 weeks with body weights of 1250-1750 grams were divided into 4 groups. Group 1 underwent a sham operation and group 2 had unilateral ureteral ligation to cause total obstruction. Groups 3 and 4 also underwent unilateral ureteral ligation but with verapamil given on day 0 and day 7 respectively. Apoptosis to the renal tubules were assessed after nephrectomy on day 14 using immunohistochemistry by counting the number cell deaths/high power field (hpf). Results: The groups that received verapamil showed significantly less apoptosis compared to those without verapamil (2,73 vs 12,46 cell deaths/hpf; p<0,05). However, there was no significant difference between groups 3 and 4 (2,73 vs 2,89 cell deaths/hpf; p>0,05), although both groups still showed more cell deaths compared to group 1 (0,38 cell deaths/hpf). Conclusion: Verapamil appears to significantly decrease apoptosis during total unilateral ureteral obstruction. However, it cannot replace the benefit of relieving total obstruction

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.

Effects of Exposure to Mixed Organic Solvents on Blood Pressure in Non-Smoking Women Working in a Pharmaceutical CompanySome studies suggest that exposure to industrial solvents can affect blood pressure. The objective of this study was to investigate the effect of a mixture of organic solvents on blood pressure in women working in a pharmaceutical company in Iran. Four hundred and thirty-three women were included in the study. Women working in packing units (group 1) were not exposed to the mixture of organic solvents, women in new laboratory units (group 2) were exposed to the mixture within the permitted range and women working in old laboratory units (group 3) were exposed to the mixture above the permitted limit. We compared systolic and diastolic blood pressures (SBP & DBP) and prevalence of hypertension and pre-hypertension among groups. The results revealed a significant difference in SBP and pre-hypertension (p<0.001) and hypertension (p<0.05) prevalence between the exposed and the control group, but DBP did not differ significantly. Logistic regression analysis showed a significant association between hypertension and exposure to mixed solvents. Odds ratio for hypertension in the group 2 and group 3 (exposed) workers was 2.36 and 3, respectively, compared to controls. Our results suggest that exposure to a mixture of organic solvents may increase SBP and hypertension and pre-hypertension prevalence in drug manufacture workers. Therefore, more attention should be paid to workers that work in such settings by periodically measuring blood pressure and implementing accurate and comprehensive programs to reduce exposure to organic solvents.

SummaryWe have previously shown abnormalities of haemostasis suggestive of intravascular coagulation in patients with malignant hypertension, a condition associated with retinopathy and renal fibrin deposition. To determine whether such abnormalities are specific to malignant hypertension, we have measured several haemostatic and haemorheological variables in 18 patients with malignant hypertension (Group 1), 18 matched healthy controls (Group 2), and 18 patients with non-malignant hypertension (Group 3) matched for renal pathology, blood pressure and serum creatinine with Group 1. Both Groups 1 and 3 had increased mean levels of fibrinogen, factor VIIIc, beta-thrombo- globulin, plasma viscosity and blood viscosity (corrected for haematocrit); and decreased mean levels of haematocrit, antithrombin III and platelet count. Mean levels of fast antiplasmin and alpha2-macroglobulin were elevated in Group 1 but not in Group 3. We conclude that most blood abnormalities are not specific to malignant hypertension; are also present in patients with non-malignant hypertension who have similar levels of blood pressure and renal damage; and might result from renal damage as well as promoting further renal damage by enhancing fibrin deposition. However increased levels of fibrinolytic inhibitors in malignant hypertension merit further investigation in relation to removal of renal fibrin.
