Abstract
Pro-and anti-inflammatory cytokines mediate the inflammatory response in sepsis. Therefore, regulation of cytokines with medications in risky situations may protect the patients from sepsis. Hydroxychloroquine and artemisinin are antimalarial drugs with immunomodulatory properties. In this study, we intended to investigate the effects of artemisinin and hydroxychloroquine on the cytokines released during sepsis in the rat model. Twenty-four rats were randomized into four groups. The control group received oral saline, the sepsis group received oral saline and intraperitoneal lipopolysaccharide toxin (LPS), the artemisinin-treated sepsis group received oral 33.33 mg/kg of artemisinin, and the hydroxychloroquinetreated sepsis group received oral 33.33 mg/kg of hydroxychloroquine before LPS injection. Three hours later, serum cytokines were measured. An increase was detected in TNF-a, IL-1, and IL-6 levels in the sepsis group compared to the control (p<0.01). Oral pretreatment with artemisinin resulted in significant downregulation only of IL-1 levels (p<0.01). Cytokines IL-1 and IL-6 were significantly downregulated in the serum of LPS-induced rats pretreated with oral hydroxychloroquine than rats with sepsis (p<0.01). Decreases observed in TNF-a and IL-10 levels were insignificant. These results demonstrated that both artemisinin and hydroxychloroquine attenuate the release of pro-inflammatory cytokines three hours after LPS-induced sepsis in rats. A significant decrease was observed in serum IL-1 and IL-6 levels with hydroxychloroquine and IL-1 levels with artemisinin. Based on our findings, we suggest that the therapeutic potential of artemisinin and hydroxychloroquine may be beneficial in preventing cytokine storm during sepsis, and further research is needed to determine the optimal timing of administration.

Abstract
OBJECTIVE Methylprednisolone is commonly used to attenuate the cytokine storm and prevent mortality in COVID-19 pneumonia. However, the optimal methylprednisolone dose and duration are unclear. Additional data are required on the effectiveness of methylprednisolone in reducing mortality in COVID-19. This real-life retrospective study aimed to analyze the data of a COVID-19 dedicated ICU and compare the mortality rates of standard care, low-dose, and pulse-dose methylprednisolone in patients requiring mechanical ventilatory support. PATIENTS AND METHODS Methylprednisolone's indication, dose, and duration were determined according to the severity of COVID-19 pneumonia based on the patient's demographic parameters, comorbidities, laboratory data, radiology, and arterial blood gas analysis results. 867 patients were grouped as: no methylprednisolone (standard care), low-dose (0.5-1 mg/kg/day) methylprednisolone or pulse-dose (250-1,000 mg/day) methylprednisolone. RESULTS The overall mortality rate was 63.78%. Adjusting the dose of methylprednisolone according to the severity of the disease resulted in statistically similar mortality rates despite the increase in disease severity. Mortality was 62.71% in standard treatment, 65.76% in low-dose, and 62.10% in pulse-dose methylprednisolone groups (p = 0.633). Invasive mechanical ventilation at admission was associated with increased mortality (HR: 1.826 [95% CI: 1.542-2.161]; p < 0.001). Hematologic disorders and malignancies, arterial blood pH and HCO3, neutrophil count, and NLR at admission were also associated with mortality. CONCLUSIONS Personalizing the dose and duration of methylprednisolone according to the patient's disease severity assessed with demographic, clinical, and laboratory results may benefit mortality in severe COVID-19 patients receiving ventilatory support in the ICU. Hematologic disorders and malignancies, arterial blood pH and HCO3, neutrophil count, and NLR at admission were associated with mortality in our patient cohort.

Abstract
Objective We aimed to investigate effects of different concentrations (0.5-5%) of Sodium Hypochlorite (NaOCl) solution on healthy tissues, and determine the optimal concentration that does not harm to tissue. Materials and Methods 30 tibias of 15 male Wistar albino rats were used. The tibias were randomly divided into 5 groups (Salin, 0.5%, 1%, 2.5%, and 5% NaOCl). Tibias were reamed intramedullary, and irrigated with 20 ml of saline or increasing concentrations of (0.5-5%) NaOCl. The tibias were embedded in paraffin and the sections were stained with hematoxylin-eosin. All sections were assessed for edema, acute inflammation, or necrosis according to their density, in bone marrow and soft tissues. Results Pairwise comparisons revealed that irrigation of tibia with saline or 0.5% NaOCl solutions was not statistically significant in terms of necrosis in the bone marrows (p=0.320). However, irrigation of rat tibia with saline caused less necrosis in the bone marrows compared to high concentrations (1%, 2.5%, and 5%) of NaOCl (saline and 1% NaOCl, p=0.017; saline and 2.5% NaOCl, p=0.0007; saline and 5% NaOCl, p=0.001). Conclusion As an irrigation solution, the effects of 0.5% NaOCl are similar to those of saline in terms of edema, inflammation, and necrosis. There is a need for evaluation of necrosis for extended periods such as one week or one month by immunohistochemical methods and flow cytometry.

Abstract
OBJECTIVE The aim of our study is to determine whether there is a change in the plasma levels of copeptin and there is a relationship among the plasma levels of carboxyhemoglobin (COHb), lactate, and copeptin levels in patients presenting to the emergency department with carbon monoxide (CO) poisoning. METHODS Fifty-seven patients admitted to the emergency department with CO poisoning were included in the study. The blood samples of the patients were collected on arrival 0th, 6th, and 12th hours for copeptin, lactate, and COHb levels. Data were analyzed using SPSS-17 statistical software. RESULTS Arrival serum copeptin levels of the patients were compared to copeptin levels of healthy individuals and a statistically significant difference was found between them (p = 0.008). There was a statistically significant difference between the arrival levels of copeptin and 6th-hour (p = 0.006) and 12th-hour (p = 0.001) levels of copeptin. There was no significant difference between 6th-hour and 12th-hour copeptin levels (p = 0.51). In terms of serum lactate levels, there was a significant difference between arrival and 6th h (p < 0.001), arrival and 12th h (p < 0.001), and 6th and 12th h (p < 0.001). Likewise, in terms of serum COHb levels, there was a significant difference between arrival and 6th h (p < 0.001), arrival and 12th h (p < 0.001), and 6th and 12th h (p < 0.001). There was a positive correlation between COHb and lactate levels on arrival (r = 0.52; p = 0.001). CONCLUSION Copeptin as a stress hormone can be used in the diagnosis and monitoring of patients with CO poisoning. However, the copeptin level was not superior to COHb and lactate levels.

Abstract
OBJECTIVES The purpose of this study was to determine the effects of hypothermia and normothermia on the isolated human saphenous vein (SV) and internal mammary artery (IMA) responses to dexmedetomidine. METHODS The response of human IMA and SV strips with (E+) and without (E-) endothelium subjected to cumulative concentrations of (10-9, 0-6 M) dexmedetomidine were recorded at 37 °C and at 28 °C. OnE-way ANOVA was used for analysis. A p < 0.05 was considered significant. RESULTS At 37˚C dexmedetomidine resulted in similar significant concentration-dependent contractions in both E+ and E- SV strips (p < 0.05). At 37 °C dexmedetomidine resulted in significant concentration-dependent contractions in E+ IMA strips, these contractions were significantly lower at all concentrations of dexmedetomidine in E- compared to E+ IMA strips (p < 0.05). When results between similar groups of SV and IMA strips were compared, the contractions were significantly higher in the IMA strips in E+ and E- at 37 °C and also E- 28 °C groups compared to SV (p < 0.05). CONCLUSION In conclusion, dexmedetomidine causes in vitro vasoconstriction in human IMA and SV grafts. These contractions are greater in IMA compared to SV grafts. Endothelium-derived pathways are possibly involved in the contractile responses of IMA. Moderate hypothermia augments vasoconstriction in SV grafts (Fig. 3, Ref. 27).

Abstract
Background The incidence of otorhinolaryngological emergencies has been steadily increasing. With the increasing number of patients admitted to the emergency room, numerous challenges in healthcare have become more prevalent. This study aimed to evaluate the epidemiological profile of otorhinolaryngological disorders in adults admitted to the emergency department of a tertiary university hospital. Materials and Methods A total of 7028 adult patients with otorhinolaryngological disorders admitted to the emergency department of a tertiary hospital from January 1 to December 31, 2016, were enrolled in the study. Each patient underwent a comprehensive clinical evaluation by the physicians of the emergency department and was consulted by an otorhinolaryngologist. Age, sex, time of visits, and cost of each patient due to healthcare insurance were recorded. Results In total, 3098 patients were male (36.6 ± 16.4 years; 44.1%) and 3930 were female (35.4 ± 16.2 years; 55.9%). The most common otorhinolaryngological disorders were pharyngitis (n = 2713; 38.6%), followed by tonsillitis (n = 1302; 18.5%) and rhinitis (n = 1161; 16.5%). These three infectious diagnoses constituted 73.6% of all otorhinolaryngological disorders. The highest number of medical visits due to otorhinolaryngological disorders was in January, whereas the lowest number of visits was in July. When we excluded the three infection-based diagnoses, otorhinolaryngological disorders were stable at approximately 150 patients per month. The main reason for the increase in the number of visits per month due to otorhinolaryngological disorders appeared to be a result of these three infection-based diagnoses. Conclusion More than 80% of otorhinolaryngological disorders in adults admitted to the emergency department were not truly emergencies requiring attendance at a tertiary hospital emergency room. New policies should be instituted to reduce the workload of the emergency services and to allow more effort to be spent on real emergencies.

Abstract
AIM To understand possible mechanisms underlying lacrimal gland degeneration when facial nerve root ischemia induces pterygopalatine ganglion injury and subsequent dry eye in a rabbit model of subarachnoid hemorrhage. MATERIAL AND METHODS Rabbits were divided into four groups: control, sham, moderate subarachnoid hemorrhage, and severe subarachnoid hemorrhage. Autologous blood recovered from the auricular artery was injected into the cisterna magna to induce subarachnoid hemorrhage in the two subarachnoid hemorrhage groups; animals were then monitored for dry eye development over 21 days before removal of their facial nerve roots, pterygopalatine ganglia, and lacrimal glands for immunohistochemical analyses. Neuronal viability in the pterygopalatine ganglia was measured; lacrimal gland vesicles were counted by stereological methods. RESULTS The mean tear-filled vesicle number and lacrimal gland volumes significantly decreased with an increase in facial nerve root injury severity and damaged neuron numbers in the pterygopalatine ganglion. Increase in injury severity most significantly decreased the tear-filled vesicle numbers in the pterygopalatine ganglion. CONCLUSION Subarachnoid hemorrhage degenerates facial nerve parasympathetic branches entering the pterygopalatine ganglion, and neuronal density in this ganglion may be correlated with tear secretion. Our data suggest that pterygopalatine ganglion degeneration following subarachnoid hemorrhage induces dry eye.

Abstract
BACKGROUND Cardiac arrest is a major life-threatening complication of subarachnoid hemorrhage (SAH). Although medullary cardiocirculatuar center injury and central sympathetic overactivity have been suspected of initiating coronary artery spasm-induced cardiac arrest, we aimed to elucidate the effects of vagal ischemia at the brainstem on coronary vasospasm and sudden death in SAH. METHODS Twenty-six rabbits were randomly divided into 3 groups. Control (n = 5); SHAM (n = 8), and SAH group (n = 13). Experimental SAH was applied by injecting homologous blood into the cisterna magna, and the SHAM group was injected with isotonic saline solution also in the cisterna magna., Twenty-one days after the injection, histopathologic changes of the neuron density of nodose ganglia, the vasospasm index values of the coronary arteries, and the electrocardiographic events were analyzed. RESULTS Increased vasospasm index of the coronary arteries and degenerated neuron density of nodose ganglion were significantly different between animals with SAH, control, and SHAM groups (P < 0.005). If neurons of the nodose ganglia are lesioned due to ischemic insult during SAH, the heart rhythm regulation by vagus afferent reflexes is disturbed. CONCLUSIONS We found that there is causal relationship between nodose ganglion degeneration and coronary vasospasm. Our finding could be the reason that many cardiac events occur in patients with SAH. Vagal pathway paralysis induced by indirect sympathetic overactivity may trigger coronary vasospasm and heart rhythm disturbances. Our findings will aid in the planning of future experimental studies and in determining the clinical relevance of such studies.

Abstract
CONTEXT Somato-sensitive innervation of bowels are maintained by lower segments of spinal cord and the blood supply of the lower spinal cord is heavily dependent on Adamkiewicz artery. Although bowel problems are sometimes seen in subarachnoid hemorrhage neither Adamkiewicz artery spasm nor spinal cord ischemia has not been elucidated as a cause of bowel dilatation so far. AIMS The goal of this study was to study the effects Adamkiewicz artery (AKA) vasospasm in lumbar subarachnoid hemorrhage (SAH) on bowel dilatation severity. SETTINGS AND DESIGN An experimental rabbit study. MATERIALS AND METHODS The study was conducted on 25 rabbits, which were randomly divided into three groups: Spinal SAH (N = 13), serum saline (SS) (SS; N = 7) and control (N = 5) groups. Experimental spinal SAH was performed. After 21 days, volume values of descending parts of large bowels and degenerated neuron density of L5DRG were analyzed. STATISTICAL ANALYSIS USED Statistical analysis was performed using the PASW Statistics 18.0 for Windows (SPSS Inc., Chicago, Illinois). Two-tailed t-test and Mann-Whitney U-tests were used. The statistical significance was set at P < 0.05. RESULTS The mean volume of imaginary descending colons was estimated as 93 ± 12 cm(3) in the control group and 121 ± 26 cm(3) in the SS group and 176 ± 49 cm(3) in SAH group. Volume augmentations of the descending colons and degenerated neuron density L5DRG were significantly different between the SAH and other two groups (P < 0.05). CONCLUSION An inverse relationship between the living neuronal density of the L5DRG and the volume of imaginary descending colon values was occurred. Our findings will aid in the planning of future experimental studies and determining the clinical relevance on such studies.

Abstract
BACKGROUND Cervical cancer is the ninth most common cancer among females in Turkey. Cervical smear is a routine screening test used for the detection of cervical abnormalities and also it detects certain infections of the cervix. OBJECTIVE To analyze cervical smear results of our clinic in order to determine most frequent pathology of the women in North Eastern Anatolia Region of Turkey. MATERIALS AND METHODS In a retrospective study design, 8,495 cervical cytology cases diagnosed at the Pathology Department of the Regional Education and Research Hospital in Erzurum over the last one and half years extending from August 2012 to December 2013 were investigated. RESULTS The most common diagnosis was found to be inflammation, 65.5 % (5,566 out of 8,495), and the least was squamous epithelial abnormalities 0.2% (13 out of 8,495). There was some variation among the three pathologists regarding diagnosis but findings for the latter. CONCLUSIONS Regular cervical smear tests are one of the most important strategies in early diagnosis of cervical cancer but there are conflicting data regarding the prevalence of epithelial cell abnormalities in Turkey, and the reasons of this should be investigated.

Abstract
The purpose of this study was to determine the effect of 3',4'-dihydroxyflavonol (DiOHF) on oxidative damage and antioxidant system in experimental testicular torsion-detorsion.The study included 60 male Wistar albino rats. Study groups were formed as follows: 1. Control; 2. Sham; 3. 720° - 4 hours torsion; 4. 720° - 4 hours torsion + 4 hours detorsion; 5. 720° - 4 hours torsion + DiOHF; 6. 720° - 4 hours torsion + DiOHF + 4 hours detorsion; 7. 720° - 4 hours torsion + 24 hours detorsion; 8. 720° - 4 hours torsion + DiOHF + 24 hours detorsion. Testis were collected for the analysis of glutathione peroxidase (GPx), nitric oxide (NO), malondialdehyde (MDA), glutathione (GSH), and xanthine oxidase (XO).GPx in the Group 8 were higher than the values in the other groups (p < 0.001). Concerning NO, the groups 3, 4, and 7 were found to have higher values than other groups (p < 0.001). MDA levels were higher in the groups 3, 7, and 8, when compared to the levels in other groups (p < 0.001). When tissue GSH levels were examined, the Group 5 had the highest GSH values (p < 0.001).With regard to XO values, the groups 3, 4, and 7 had the highest XO values (p < 0.001). The results of the study indicated that intraperitoneal DiOHF inhibited increased lipid peroxidation in testis ischemia-reperfusion injury in rats (Tab. 5, Ref. 46).

Abstract
OBJECTIVE Gynaecological oncological surgery (GOS) includes a wide variety of surgical procedures and postoperative pain is a major concern. This study compared the impact of intrathecal morphine (ITM) plus patient-controlled analgesia (PCA) with PCA alone on morphine consumption, pain relief and patient satisfaction after GOS. METHODS Sixty women undergoing GOS under general anaesthesia were randomized to receive either 0.3 mg ITM or placebo. On arrival at the postanaesthesia care unit each patient received a morphine PCA pump. The three primary outcome measures were pain, patient satisfaction scores evaluated using a 100-mm visual analogue scale and cumulative PCA morphine consumption. RESULTS No significant differences were observed in the demographic data. Cumulative PCA morphine consumption was significantly lower in the ITM group compared with the control group. Fatigue scores were lower in the ITM group compared with the control group but did not reach statistical significance. Pain, sedation and patient satisfaction scores, and the rate of side-effects were similar for the two groups. CONCLUSIONS Administering ITM in GOS could improve postoperative analgesia and reduce morphine consumption without serious side-effects.

Abstract
A 4 year-old boy was admitted to our clinic with symptoms of pain and ecchymosis in his right leg and foot after injection of benzathine penicilline. There was a localized gangrenous area at the femoral injection site. Doppler ultrasonography showed no arterial flow in the femoral artery and clear evidence of acute thrombosis of the superficial femoral and popliteal veins. Femoral arterial and venous thrombectomy and fasciotomy were performed immediately. After surgery the boy was treated by Iloprost infusion and enoxaparine. One week later necrotic changes had regressed, fasciotomies were closed and only the distal phalanx of the third toe needed amputation. Early surgical intervention and standard management combined with Iloprost infusion may help in healing the lesions by increasing extremity perfusion and may prevent extremity loss.

Abstract
BACKGROUND AND OBJECTIVE Pain on injection is still a problem with propofol. The purpose of the study was to compare the effectiveness of diphenhydramine and lidocaine on pain caused by propofol at the site of injection. METHODS One hundred and eighty ASA I-II adults undergoing elective surgery were randomly assigned into three groups of 60 each. Group I (placebo) received 2 mL normal saline, Group II received 2 mL (40 mg) 2% lidocaine and Group III received 2 mL (20 mg) diphenhydramine intravenously (i.v.) during a 1-min venous occlusion, followed by propofol into a cephalic forearm vein of the antecubital fossa. Pain assessment was made immediately after propofol injection. RESULTS In the placebo group 25 (41.7%) patients experienced pain during propofol injection as compared to 2 (3.3%) and 3 (5.0%) in the lidocaine and diphenhydramine groups, respectively. The prevalence of pain and pain score were significantly less in both the lidocaine and diphenhydramine groups than in the placebo group (P = 0.00). No difference was found between the diphenhydramine and lidocaine groups (P = 0.60). CONCLUSION Previous injection of diphenhydramine with venous occlusion can be considered as an alternative to lidocaine for reducing the prevalence of pain caused by injection of propofol into peripheral veins.

Abstract
The purposes of this study were to evaluate the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on acute nonvaricose upper gastrointestinal bleeding (ANUGIB) and establish whether the NSAID-prescribing physicians take precautions to prevent or reduce GI ulcerations. Clinical characteristics, causes of bleeding and clinical outcomes of patients hospitalised in our gastroenterology clinic with ANUGIB were recorded prospectively over a 1.5-year period. NSAIDs, including aspirin, were used by 127 of 168 patients (73%). Among the NSAID users, 100 patients (78%) had at least one risk factor for serious adverse GI events related to NSAIDs. Only two patients were using proton pump inhibitors and one patient was using H2 receptor blocker of the high-risk group for GI side effects of NSAIDs. NSAIDs have an important effect on GI bleeding, and it seems that risk factors are underestimated by physicians.

Abstract
BACKGROUND This study was designed to evaluate the effects of intrathecal isobaric bupivacaine 0.5% plus morphine and isobaric ropivacaine 0.5% plus morphine combinations in women undergoing Caesarean deliveries. METHOD Twenty-five parturients received ropivacaine 15 mg and morphine 150 micro g (RM group) and twenty-five parturients received bupivacaine 15 mg and morphine 150 micro g (BM group) for spinal anaesthesia. Sensory and motor block, haemodynamics, postoperative analgesia, fetal outcomes, and side-effects were evaluated. RESULTS Intrathecal bupivacaine-morphine and ropivacaine-morphine provided effective sensory anaesthesia and motor block. Time to reach complete motor block was shorter and time to complete recovery from motor block was longer in the BM group than the RM group (P<0.05). The time to regression of two dermatomes and time for the block to recede to the S2 dermatome were similar in both groups (P>0.05). Time to first complaint of pain and the mean total consumption of tenoxicam were similar in both groups (P>0.05). APGAR scores at 1 and 5 min were similar in the two groups, as were mean umbilical blood pH values (P>0.05). Hypotension and pruritus were the most common side-effects in both groups during the operation. CONCLUSION Intrathecal isobaric ropivacaine 0.5% 15 mg plus morphine 150 micro g provides sufficient anaesthesia for Caesarean delivery. The ropivacaine-morphine combination resulted in shorter motor block, similar sensory and postoperative analgesia.

Abstract
We studied the effects of nimodipine on brain tissue lactate and malondialdehyde (MDA) levels one hour after experimental head trauma in 25 New Zealand rabbits. Group 1 (n=5) was the sham operated group. Group 2 (n=10) received head trauma without treatment and in group 3 (n=10) nimodipine was administered for 30 minutes intravenously (2 microg/kg/min) immediately after head trauma. In groups 2 and 3, tissue samples from the non-traumatized side was named as "a" and traumatized side as "b". The lactate and malondialdehyde contents were significantly higher in groups 2a, 2b, 3a and 3b when compared with to group 1 (P<0.05). The differences between non-treated groups (2a, 2b) and nimodipine treated groups (3a, 3b) were not significant (P>0.05). The differences between the traumatized sides (2b, 3b) and non-traumatized sides (2a, 3a) were significant (P<0.05). These results demonstrated that nimodipine is ineffective in suppressing the increase of tissue lactate and malondialdehyde levels in the early period of experimental head trauma.

Abstract
BACKGROUND We studied the effects of sevoflurane on intraocular pressure after induction in children undergoing either tracheal tube (TT) or laryngeal mask airway (LMA) insertion without a muscle relaxant METHODS The study included 38 children. Anaesthesia was induced (8%) and maintained (3-4%) with sevoflurane in 100% O2. No muscle relaxant was used. A TT was inserted in group I (n=20), and an LMA in group II (n=18). IOPs were measured after induction, insertion of TT or LMA and at 1, 2 and 3 min thereafter. The heart rate, mean arterial pressures were also recorded. RESULTS Intraocular pressures increased significantly in group I after TT (P < 0.01) and remained high until after 3 min. The pressures were similar in the LMA group at all measurements. CONCLUSION Sevoflurane does not prevent the increase in IOP after intubation without muscle relaxants. LMA does not increase IOP in children after sevoflurane induction.

Abstract
To examine the effects of calcium antagonists nimodipine and magnesium sulfate (MgSO4) on tissue endogenous antioxidant levels, the authors studied superoxide dismutase (SOD) and glutathione peroxidase (GPx) levels in rabbit brain 1 hour after experimental head trauma. Forty New Zealand rabbits were anesthetized and randomly divided into four groups. Group 1 (n = 10) was the sham operated group. Group 2 (n = 10), the control group, received head trauma and no treatment. Group 3 (n = 10) received head trauma and intravenous (IV) 2 microgr/kg nimodipine. Group 4 (n = 10) received head trauma and IV 100 mg/kg MgSO4. Head trauma was delivered by performing a craniectomy over the right hemisphere and dropping a weight of 20 g from a height of 40 cm. In the right (traumatized) hemisphere, SOD and GPx decreased by 57.60% +/- 9.60% and 72.93% +/- 5.51% respectively from sham values. Magnesium sulfate, but not nimodipine, reduced the magnitude of decrease of SOD and GPx to 19.43% +/- 7.15% and 39.01% +/- 7.92% respectively from sham values. In the left (nontraumatized) hemisphere, MgSO4 increased SOD to 42.43% +/- 24.76% above sham values. The authors conclude that MgSO4 treatment inhibited the decrease in SOD and GPx levels in experimental brain injury.

Abstract
OBJECTIVE To determine the effects of magnesium sulfate (MgSO4) on tissue lactate and malondialdehyde (MDA) levels in rabbit brain after experimental head trauma. DESIGN Prospective, randomized trial. SUBJECTS Thirty New Zealand rabbits. INTERVENTIONS Group 1 (n = 10) was the sham operated group. Group 2 (n = 10) (untreated group) and group 3 (n = 10) received head trauma with the weight drop method. MgSO4 was administered 100 mg/kg (15 %) i. v. immediately after the head trauma to group 3. Trauma was applied to one side. The non-contused side was named as "a" and the contused side as "b". MEASUREMENTS One hour after trauma, brain cortices were resected and the concentrations of lactate and MDA were determined using the spectrophotometric enzymatic and thiobarbituric acid methods. One-way ANOVA and Tukey's HSD tests were used for the evaluation of the results. P < 0.05 was considered as significant. Pearson's correlation test was used between lactate and MDA levels (P < 0.001). RESULTS There were significant differences between MDA and lactate levels of group 1 and all other groups; non-contused (a) and contused (b) sides of groups 2 and 3; groups 2b-3a, 2b-3b (P < 0.05). The difference in MDA levels was significant between groups 2a-3b (P < 0.05). Correlation between lactate and MDA was very good in group 1, and excellent in groups 2a, 2b, 3a, and 3b. CONCLUSIONS These results demonstrate that head trauma leads to an increase in brain tissue lactate and MDA levels, and MgSO4 suppresses the rise in contused tissue when given after head trauma.

Abstract
Lymphoproliferative diseases are the most common disorders associated with autoimmune disturbances. We determined the autoimmune phenotype of 64 non Hodgkin's lymphoma patients' and compared their clinicopathologic properties. Serum direct antiglobulin test [(DAT) n=64], indirect antiglobulin test [(IAT) n=61], platelet autoantibodies [(PAA) n=51], anti nuclear antibodies [n=33], anti-native DNA [n=29], anti phospholipid antibodies [n=40] and, lupus anticoagulant [n=33] were used as autoimmune markers. Twenty five patients (39%) displayed one or more autoimmune marker positivity (+). Three patients with (+) DAT and IAT had autoimmune hemolytic anemia and two patients with PAA had autoimmune thrombocytopenia. Male patients were more susceptible to autoimmunity in low grade lymphomas and the statistical difference was significant (p=0.035). Most of the autoimmune markers (+) patients had low grade and disseminated disease but this was not significant. Remission rates were not found to be different between autoimmune marker (+) and (-) patients. Although statistically not significant. median survival was longer in autoimmune marker (-) patients than in the others (50 versus 39 months). The significance of autoimmunity in NHL in a larger series of patients should be investigated in future studies.

Abstract
The aim of this study was to prevent the complications of gastrocystoplasty by using reversed seromuscular gastrocystoplasty for bladder augmentation. Healthy mongrel dogs were used in the study. A diamond shaped segment was separated from the remainder of the stomach preserving the right gastroepiploic artery in 11 dogs. The gastric mucosa was removed. A reversed seromuscular gastrocystoplasty was performed. The animals were observed for a mean of 7.7 months. Thereafter, relaparotomy was performed in all animals. A bladder stone was found in 1 dog. In the histopathological evaluation of the urinary bladder, it was seen that the gastric serosal surface was covered with the urothelium in all dogs. Transitional epithelial hyperplasia in 1 dog (12.5%) and squamous metaplasia in 2 dogs (25%) were identified. There were no statistical differences between preoperative and postoperative values of urine and blood pH and serum sodium, potassium, chloride, and bicarbonate levels. Complications of gastrocystoplasty such as hypochloremic metabolic alkalosis and hematuria and dysuria syndrome, are prevented by this procedure. The shrinkage of the gastric patch surface may also be prevented by facing the smooth gastric serosa to the internal surface of the urinary bladder.

Abstract
Four-hundred-and-fifteen neonates were evaluated by echocardiographic means in order to detect interatrial septal openings and were followed for a maximum time of 18 months. In 68.67% of them, interatrial septal openings were present at the first week of life. The defects were larger than 3 mm in 50.18% of these infants. At the end of the 18th month, openings persisted in 3 cases. The statistical analyses showed significant difference about the percent of closing between the groups with initial opening sizes lesser and bigger than 3 mm. Also, there was a positive correlation between the initial size and the spontaneous closure time. Spontaneous closure incidences were not different in boys and girls. In a small group of infants (4.64%), interatrial openings close forming septal aneurysms. In 12.3% of the newborns without an opening, septal aneurysms were detected during the initial evaluation.
