Paraoxonase and Arylesterase Activities, Lipid Profile, and Oxidative Damage in Experimental Ischemic Colitis Model
Objective. In the present study, since PON1 is known as an HDL-associated antioxidant enzyme that inhibits the oxidative modification of LDL and oxidative stress plays a role in the pathogenesis of mesenteric ischemia, we investigated the changes in PON1 activity and lipid profile in an experimental ischemic colitis model. Methods. Forty male Wistar albino rats were divided into two groups: the control group (N = 15) and the experimental group (N = 25). All animals were anesthetized with ether and ketamine anesthesia to undergo a midline laparotomy. Ischemic colitis was induced by marginal vessel ligation in the splenic flexura (devascularization process). A sham laparotomy was performed in the control group. All animals were sacrificed on the seventh postoperative day. Oxidative stress marker (malonyldialdehyde, MDA), lipid profile, and paraoxonase (PON-1) and arylesterase activities were determined. Histopathological evaluation was done under light microscopy, after sectioning and staining with hematoxyline and eosin. Statistical analysis was conducted using Student's t-test and Mann-Whitney U test, and P 0.05).Conclusions. PON1 and arylesterase play an important role in the pathophysiology of ischemic colitis
Reversible hypertensive brainstem encephalopathy coexistent with acute intracerebral hemorrhage
We report two cases of reversible hypertensive brainstem encephalopathy (RHBE) syndrome with other concurrent manifestations of malignant hypertension. RHBE was accompanied by hypertensive putaminal hemorrhage in one case, and by intra-ventricular hemorrhage resulting acute obstructive hydrocephalus along with multiple small acute infarctions in the other. Diffusion-weighted imaging and corresponding apparent diffusion coefficient mapping disclosed increased diffusion suggestive of vasogenic edema centered in the pons. No lesion indicative for posterior reversible encephalopathy syndrome (PRES) was noted in the supratentorial regions. These cases indicate that mechanisms involved in development of RHBE and hypertensive PRES may have some differences, albeit both share main lines. These cases also underline that awareness and knowledge about relatively specific clinic-radiological syndrome caused by RHBE seem to be critical. Acute treatment and early prognostification are just only accurate with such a familiarity
The frequency of Duchenne muscular dystrophy/Becker muscular dystrophy and Pompe disease in children with isolated transaminase elevation: results from the observational VICTORIA study
IntroductionElevated transaminases and/or creatine phosphokinase can indicate underlying muscle disease. Therefore, this study aims to determine the frequency of Duchenne muscular dystrophy/Becker muscular dystrophy (DMD/BMD) in male children and Pompe disease (PD) in male and female children with isolated hypertransaminasemia.MethodsThis multi-center, prospective study enrolled patients aged 3–216 months with serum alanine transaminase (ALT) and/or aspartate transaminase (AST) levels >2× the upper limit of normal (ULN) for ≥3 months. Patients with a known history of liver or muscle disease or physical examination findings suggestive of liver disease were excluded. Patients were screened for creatinine phosphokinase (CPK) levels, and molecular genetic tests for DMD/BMD in male patients and enzyme analysis for PD in male and female patients with elevated CPK levels were performed. Genetic analyses confirmed PD. Demographic, clinical, and laboratory characteristics of the patients were analyzed.ResultsOverall, 589 patients [66.8% male, mean age of 63.4 months (standard deviation: 60.5)] were included. In total, 251 patients (188 male and 63 female) had CPK levels above the ULN. Of the patients assessed, 47% (85/182) of male patients were diagnosed with DMD/BMD and 1% (3/228) of male and female patients were diagnosed with PD. The median ALT, AST, and CPK levels were statistically significantly higher, and the questioned neurological symptoms and previously unnoticed examination findings were more common in DMD/BMD patients than those without DMD/BMD or PD (p < 0.001).DiscussionQuestioning neurological symptoms, conducting a complete physical examination, and testing for CPK levels in patients with isolated hypertransaminasemia will prevent costly and time-consuming investigations for liver diseases and will lead to the diagnosis of occult neuromuscular diseases.

and Ertaş 31(1): 30-39 (2016)doi: 10.18864/TJAS201604Determination of Water Quality of Arılı Stream (Rize) in Terms of Physico-Chemical Structure This study was carried out purposing to determine water quality of Arılı Stream located in Fındıklı, Rize at Eastern Black Sea Region between October, 2013 and September, 2014. During the study, the water samples were taken periodically from seven chosen stations in every month. The measured data were given as following (minimum, maximum and average): water temperature (6.7518.21-9.68 0.27 C), pH (6.81-8.11-7.330.03), dissolved oxygen (7.53-13.20-9.360.13 mg/L), conductivity (61.2-82.9-73.83 0.45 µS/cm), nitrite nitrogen (NO2?-N)(0.0009-0.0092-0.0042 0.0002 mg/L), nitrate nitrogen (NO3?-N)(0.81-5.29-1.58 0.09 mg/L) and ammonium nitrogen (NO4-N)(0.0001-0.0097-0.0026 0.0003 mg/L). When the physical and chemical characteristics of Arılı Stream were examined according to the inland water quality standards declared in water pollution law, it is obvious that the river has a high water quality standard (Class I). Thus, it can be said that Arılı Stream water can be used not only for drinking purpose by disinfecting it, but also for recreational aims, aquacultures and other aims. GİRİ
