The objective of this study was to confirm the effects of curcumin and to investigate the effects of its combination with a reduced dose of rosuvastatin in an adenine-induced model of chronic kidney disease (CKD) and associated dyslipidemia in rats. Renal function and morphology, as well as lipid status, were assessed using laboratory parameters and histopathological analysis. Male Wistar rats (n=36) randomly divided into six groups, were treated for 24 days: normal control (standard diet), CKD control (adenine diet, 0.

Aim To determine the value of angles between the left coronary artery main trunk (LMT) and its branches, the anterior interventricular branch (LAD) and the circumflex branch (CX), and their possible relationship with the LMT length. Methods A total of 29 cadaveric hearts were used. The left coronary artery and its branches were dissected.

Background: Zearalenone is a widely spread mycotoxin, contaminant of most cereal grains. It has uterotropic, estrogenic and anabolic activity in farm animals. The results are hormonal disbalances as hyperestrogenism, Zearalenone inhibits follicle-stimulating hormone production, thus supressing ovarian follicle development and ovulation.

Objectives: The aim of this study was to investigate the effects of pinealectomy and melatonin treatment on the rat thymus gland characteristics, taking into consideration possible gender differences.

Materials And Methods: Thirty adult Wistar rats of both sexes were divided into three groups. Group C and group PX served as control groups and included sham-pinealectomized and pinealectomized animals that were treated with 10% ethanol solution (0,1ml/daily, subcutaneous).

The aim of this research was to assess the reactive changes of rat proximal tubules caused by gentamicin and the effect of relatively low doses of melatonin. 48 adult male Wistar rats were distributed into six groups of equal size which all received one of the following daily intraperitoneal injections: vehicle (5% ethanol in Ringer solution) during 11 days (C); gentamicin (80 mg/kg) during 8 days (G), two groups which concomitantly received gentamicin (80 mg/kg) during 8 days and melatonin in two different test doses (5 or 20 mg/kg) during 11 days (GM1, GM2) and two groups treated only with melatonin in two different doses (5 or 20 mg/kg) during 11 days (M1, M2). Histological analysis included qualitative and semi-quantitative light microscopy analysis of proximal tubules.

We have investigated heart type fatty acid binding protein (H-FABP) rat serum values at different time point following subcutaneous (s.c) isoproterenol (ISO) administration and their correlation with severity of myocardial lesion. Thirty adult, male, Wistar rats were used for this study.

The advent of multicellular organisms was accompanied by the development of short- and long-range chemical signalling systems, including those provided by the nervous and endocrine systems. In turn, the cells of these two systems have developed mechanisms for interacting with both adjacent and distant cells. With evolution, such mechanisms have diversified to become integrated in a complex regulatory network, whereby individual endocrine and neuro-endocrine cells sense the state of activity of their neighbors and, accordingly, regulate their own level of functioning.

The present study was carried out to evaluate the renoprotective antioxidant effect of Spirulina platensis on gentamicin-induced acute tubular necrosis in rats. Albino-Wistar rats, (9male and 9 female), weighing approximately 250 g, were used for this study. Rats were randomly assigned to three equal groups.

Seven days after the application of 2% lidocaine (4 ml doze, the speed of application 3 ml/min, mean application pressure 15 +/- 2.47 kPa) into mesoneurium of adult rabbit sciatic nerve, a nerve segment was intravitally excided from the injection site with a length of 1 cm and qualitatively and quantitatively analyzed. Histological changes at the level of total nerve structures were found, especially of its sheaths.

Pineal gland has and antistressogenic role. Its main hormone, melatonin, has radio protective effect on endocrine and other dynamic tissues. In our previous study, we have shown that pinealectomy changes the behavior of suprarenal gland in totally irradiated rats.

Haloperidol (4'-fluoro-4-[4-Hydroxy-4-p-chlorophenylpiperidino]-Butyrophenone), a neuroleptic, drug is the first choice in the treatment of schizophrenia. Experimental studies on rats show that haloperidol, at female, causes: decreasing of the ovarian weight, inhibition of the ovulation, producing a state of distrust and stimulation of lobuloalveolar development of the mammary glands and increasing of serum prolactin levels in both male and female rats. At male rats haloperidol causes damage of Leydig cells and cells depletion of seminal lineage with sequels on the excretory ducts level and accessory genital glands.

In the last few decades there has been a great development of regional anesthesia; all the postulates are defined and all the techniques of usage are perfected. However, like any other medical procedure, the block of brachial plexus carries a risk of certain unwanted complications, like possible intraneural and intravascular injections. The reason for great discrepancy between the injury of brachial plexus and other periphery nerves while performing the nerve blockade is the frequent usage of this block, but also the specific proximity of neurovascular structures in axilla.

Histological changes of sciatic nerve in adult dogs 7 days after single application of 2% lidocaine (4 ml dose, speed of injection 3 ml/min) and measurement of the application pressure was studied, with a goal to investigate structural changes of the nerve in relation to the established pressure values. The application pressure was determined by using Bio Bench software. In intrafascicular puncture an average application pressure of 198.

Background: Unintentional intraneural injection of local anesthetics may cause mechanical injury and pressure ischemia of the nerve fascicles. One study in small animals showed that intraneural injection may be associated with higher injection pressures. However, the pressure heralding an intraneural injection and the clinical consequences of such injections remain controversial.

Melatonin, the major product of the pincal gland, is also synthesized in the retina of several vertebrate species. Retinal melatonin levels show a marked daily variation, with high levels at night and low levels during the light period. Melatonin rhythm generating system includes photodetector, circadian clock and melatonin synthesis machinery and they are located in pincal organ and retina.
