The aim of  the  study  was  to  analyze  the  microvasculation  of  the  liver  in  administration  of  tautomeric forms of orotic acid for a methionine-induced liver pathology to assess the efficacy of the modified drugs and the potentialof their clinical use.Material and  methods. The  study  included  30  white  outbred  rats,  that  were  simulated  methionine induced hyperhomocysteinemia by the administration of methionine, dosage 0.15 g/100 g of the body we ight, via food  during  4  weeks.  Animals  with  hyperhomocysteinemia  were  divided  into  4  groups:  animals  of  group  1  received orotic acid (OA) in the initial form (oxo-tautomer), animals of group 2 received hydroxy–tautomer OA after mechanomodification for 1 hour, animals of group 3 received dihydroxy-tautomer OA after mechanomodification for 6 hours. Histological preparations of the liver were used to evaluate the area of hepatocytes; diameters and areas of the central vein, the interlobular vein and artery, the bile duct, and the Visotto coefficient were calculated.Results. Morphometric  data  of  the  hepatic  microvascular  bloodstream  with  simulated  hyperhomocysteinemia evidenced a general increase in the diameter and area of blood vessels, changes affected the system of blood inflow and outflow at the organ level. Administration of OA had a normalizing effect on the liver bloodflow, but the effects were different: the most pronounced effect was detected in administration of the hydroxy-form of the preparation, this can be explained by a modificationin the dispersion of the preparation (without changing the crystal lattice), an increase in the rate of dissolution in water and aqueous solutions, an increasein the number of functionally active groups in the heterocycle of the hydroxy-form of OA. Thus, the hydroxy-tautomer of orotic acid had the greatest efficacy relating to vasodilation of microvessels of the liver bloodstream in hyperhomocysteinemia; the fact suggesting feasibility of its further study in the clinical environment.

This study was conducted to find out hepatoprotective activity of hesperidin (HES) 100mg/kg body weight (b.w.) against ciprofloxacin (CPX) 100 mg/kg induced hepatotoxicity in local breed rabbits .CPX is a broad spectrum antibiotic used for treatment of many bacterial infections. Twenty four male rabbits were divided into four groups ,group1: control, (1 ml/kg Saline orally) group 2: CPX (100 mg/kg orally) for (14) consecutive days , group 3: HES (100 mg//kg) orally for (14) consecutive days group 4: CPX (100 mg/kg orally) plus HES (100 mg//kg orally ) for (14) consecutive days. All the rabbits were killed on the (15) day of the experiment, and then the blood, and livers samples were taken. CPX induced hepatotoxicity was proved by a significant (p less than 0.01) reduction in the body weight ,and a significant (p less than 0.01) increased serum aspartate transaminase (AST), alanine transaminase (ALT) , Malonaldehyde enzyme (MAD) and histopathological changes. Protective hepatic toxicity effect and oxidative damage caused by CPX significantly (p less than 0.01) increasing in body weight and significantly (p less than 0.01) decreasing AST , ALT, MAD and improving tissue morphology in HES (100 mg//kg) . These results assure that HES (100 mg//kg) antioxidant effects can protect CPX-induced hepatotoxicity in rabbits.

Study design: Four groups, between-subjects study. Objectives: To investigate the effects of exercise on adaptation of normal subjects who had been artificially spatially disoriented. Background: Many patients referred for rehabilitation experience sensory changes, due to age or disease processes, and these changes affect motor skill. The best way to train patients to adapt to these changes and to improve their sensorimotor skills is unclear. Using normal subjects, we tested the hypothesis that active, planned head movement is needed to adapt to modified visual input. Methods and measures: Eighty male and female subjects who had normal balance on computerized dynamic posturography (CDP) and the dynamic gait index (DGI), were randomly assigned to four groups. All groups donned diagonally shift lenses and were again assessed with CDP and DGI. The four groups were then treated for 20 min. Group 1 (control group) viewed a video, Group 2 performed exercise that involved translating the entire body through space, but without separate, volitional head movement, Group 3 performed exercises which all incorporated volitional, planned head rotations, and Group 4 performed exercises that involved translating the body (as in Group 2) and incorporated volitional, planned head motion (as in Group 3). All subjects were post-tested with CDP and DGI, lenses were removed, and subjects were retested again with CDP and DGI. Results: The groups did not differ significantly on CDP scores but Groups 3 and 4 had significantly better DGI scores than Groups 1 and 2. Conclusions: Active head movement that is specifically planned as part of the exercise is more effective than passive attention or head movements that are not consciously planned, for adapting to sensorimotor change when it incorporates active use of the changed sensory modality, in this case head motion.

Background: We investigated whether the frequency of lower urinary tract symptoms (LUTS) increased in patients in whom double-J stents were applied. We also evaluated several medical therapy protocols to treat symptoms related with ureteral stents.Materials and Methods: A total of 108 patients, in whom unilateral double-j stent was applied during ureteral stone treatment, were included. Before the double-J stent was applied, all patients completed storage components of the “International Prostate Symptom Score” (IPSSs), quality of life components of the IPSS (IPSS-QOL) and “Overactive Bladder Questionnaire” (OABq) forms and scores were calculated. After the procedure, cases were randomized into 5 groups, an antiinflammatory was given to Group 1, spasmolytic to Group 2, anticholinergic to Group 3 and α-blocker to Group 4. No additional drug was given to Group 5 as this control group. During the fourth week of the procedure, IPSSs, IPSS-QOL and OABq forms were again completed and scores were compared with the previous ones.Results: When all the cases were evaluated, the IPSSs, IPSS-QOLand OABq scores of patients in whom the double-J stent was applied were statistically significantly higher the procedure. Compared to the control group, the cases where the double-J stent was applied showed a higher IPSSs, IPSS-QOL and OABq scores and none of the medical therapies could prevent this increase.Interpretation: The frequency of LUTS increased in cases where the ureteral stent was applied and discomfort continued as long as the stent stayed in the body.

In medical sciences, toxicity is an area wherein extensive studies have been carried to improve the diseases as well as to prevent. So, there is a high requirement for novel and improved alternative therapeutic strategies to manage diseases. The liver is the largest gland in the body, which executes several important mechanisms; it stores minerals and vitamins and releases them in periods of need. The main aim of this study was to give a closer insight into potent non- toxic compounds that is capable of modifying the responses. Animals were divided into five equal groups viz control (Group 1), administered with food and water ad libitum, (Group 2) administered with olive oil, (Group 3) administered with zingerone, (Group 4) administered with concanavalin A, (Group 5) administered with cyclosporine A followed by zingerone. Our results revealed significant changes in liver marker enzymes and liver histology of zingerone treated rats when compared to control rats.  A corollary, zingerone has no toxic effect on hepatocytes and was found to be safe at a dose of 10mg/kg b wt and also ameliorates hepatotoxicity.

Background Hypothyroidism is a metabolic disorder affecting the functions of many tissues in the body including the testis. Testis is rich in the polyunsaturated fatty acids content and lacks strong intrinsic antioxidant system making it prone to such oxidative stress. L-carnitine (LC) regulates long chain fatty acids metabolism; and is considered a valuable antioxidant factor. Aim It was to evaluate the effect of hypothyroidism induced by propylthiouracil (PTU) on rats’ testes and the possible protective role of LC. Methods Forty-eight adult male albino rats were used in this work. The animals were divided into three groups with sixteen animals in each. Group 1 (Control): Animals were kept without medications. Group 2 (PTU-treated): was subjected to administration of PTU; while group 3 (PTU and LC) received both PTU and LC. By the end of the experiment “30 days”, blood samples were taken for hormonal assay; then animals were anaesthetized and sacrificed. Specimens were homogenized for biochemical analysis; epididymal content of each rat was obtained immediately for semen analysis. Testes’ specimens were harvested, prepared and examined by light microscope examination. Results Induced hypothyroidism was noticed to cause histopathological, morphometric and biochemical changes in rat’s testes. LC protected the testicular specimens against such changes; it also improved the seminal quality and quantity as well as testicular structure and biochemistry. Conclusion Hypothyroidism could result in hazards to the structure of testis. Fortunately co-administration of LC might reduce such hazards.

Introduction. The influence of the dental apparatus on the balance of the body in an upright position has been widely discussed in the literature for several decades. Examination of the patient taking into account his postural balance makes it possible to clarify the reasons for the low effectiveness of pain syndromes treatment of the craniocervical region caused by malocclusion, as well as ineffective correction of musculoskeletal dysfunction of the temporomandibular joint (MSD TMJ) associated with posture disorders.The aim of the study is to evaluate the effectiveness of treatment of patients with dental anomalies and musculoskeletal dysfunctions of the temporomandibular joint and concomitant somatic dysfunctions (if any) by methods of orthodontic and osteopathic correction.Materials and methods. The study involved 102 patients aged from 18 to 45 years with TMJ. All patients underwent orthodontic and osteopathic examination. 3 groups of patients were formed: № 1 — exclusively with dental anomalies TMJ (occlusive dysfunction), who received only orthodontic treatment, № 2 with concomitant somatic (extra-occlusive) dysfunctions, who received only orthodontic treatment, and №3 with concomitant somatic (extra-occlusive) dysfunctions, who received both orthodontic and osteopathic treatment. Orthodontic treatment of musculoskeletal dysfunction of the TMJ consisted of the occlusive kappa manufacturing. Osteopathic correction was carried out individually, taking into account the identified somatic dysfunctions, on average 3 sessions. Patients also received drug therapy, and they performed myohymnastics for the masticatory muscles. The clinical dysfunction index (Helkimo M.) was used to control the elimination dynamics of the TMJ's musculoskeletal dysfunction symptoms. The assessment of the pain dynamics in the TMJ was carried out by a visual-analog scale (VAS). The evaluation of the osteopathic treatment effectiveness was carried out on the basis of computer stabilometry data and osteopathic examination data. A stabilometric study was performed on the «ST-150» («Biomera») stabiloplatform in the Romberg sample (European foot installation) with open and closed eyes in two positions of the lower jaw: 1) in a state of physiological rest (tooth rows are separated); 2) in the kappa with closed tooth rows.Results. The MSD TMJ symptoms were eliminated 10 weeks after the start of treatment in all (100 %) patients of group № 1 and group № 3. Among the patients in group № 2, only 12,1 % of patients had complete absence of MSD TMJ symptoms, while all patients in this group had a statistically significant decrease in the clinical index of Helkimo dysfunction. In one third of the group № 2 patients on the 12th week of orthodontic treatment, headaches and/or pains in other parts of the musculoskeletal system (neck, back, shoulders, arms) prevailed among complaints and which were previously indicated in the anamnesis. This occurred after the elimination of the MSD TMJ symptoms. The absolute majority of patients in group № 3 (97,1 %) noted the complete disappearance of headaches and/or pains in other parts of the musculoskeletal system (neck, back, shoulders, arms). Also, in patients of this group, stabilometric indicators were normalized in a state of physiological rest and in the kappa.Conclusion. Patients with somatic dysfunctions need complex treatment with the participation of an osteopath and a dentist. When assessing the osteopathic status of a patient, it is important to determine whether the patient has only occlusive dysfunctions or there are also extra-occlusive ones. Additional osteopathic correction is recommended for patients with extraocclusive dysfunctions in order to achieve treatment results comparable in effectiveness and timing.

Introduction: Hyperthyroidism increases the basal metabolic rate and affects most systems in the body. Patients with hyperthyroidism have been shown to have a higher incidence of ischemic stroke. There is a paucity of information regarding its effects on the short-term outcomes of patients admitted with ischemic stroke. Hypothesis: Hyperthyroidism is associated with worse in-hospital outcomes in patients admitted for ischemic stroke. Methods: We queried the National Inpatient Sample to identify adult patients(aged 18 and above) admitted for ischemic stroke between January 2011 and December 2014. We compared those with a history of hyperthyroidism (group 1) and thyrotoxicosis on admission (group 2) with the rest of the patients (group 3). The main outcome was in-hospital mortality. Secondary outcomes included the length of hospital stay and cost of hospitalization. We used the logistic regression model and adjusted for baseline characteristics and co-morbidities. Results: There were 643,786 patients in the study, 0.44% had a history of hyperthyroidism, and 0.01% had thyrotoxicosis at the time of presentation. The odd of mortality in group 1 compared to group 3 was 0.89, 95% CI 0.75-1.05, p=0.16 while in group 2 compared to group 3, it was 2.42, 95% CI 1.29-4.52, p<0.006. The mean length of stay was also longer in group 2 with a mean difference of 8.06, 95% CI 4.74 - 11.39, p<0.0001. Conclusion: From the study, there was no significant difference in in-hospital mortality between patients with previously diagnosed hyperthyroidism and those without diagnosed hyperthyroidism. Patients who had thyrotoxicosis on admission, on the other hand, had worse outcomes compared to patients without thyrotoxicosis.

This study was performed to test the hypothesis that tissue O2 extraction capabilities during hemorrhage may be greater when hematocrit (Hct) is initially reduced. Twenty-four anesthetized and splenectomized dogs were randomly assigned in three groups of eight dogs each: group 1 (Hct 40), 40–45% Hct; group 2 (Hct 30), 30–35% Hct; and group 3 (Hct 20), 20–25% Hct. In each animal, the desired Hct was obtained by normovolemic hemodilution using hydroxyethyl starch 450/0.7 and maintained throughout the experiment. O2 delivery (DO2) was progressively reduced by hemorrhage. At each step, DO2 and O2 consumption (VO2) were measured separately. Critical DO2 obtained from a plot of VO2 vs. DO2 was lower in the Hct 30 and Hct 20 groups than in the Hct 40 group [(in ml.min-1.kg-1) Hct 30, 7.9 +/- 2.2; Hct 20, 7.8 +/- 1.0; Hct 40, 10.4 +/- 1.1; P < 0.05]. Critical DO2 obtained from blood lactate levels was also significantly lower in the Hct 30 and Hct20 groups than in the Hct 40 group. Critical O2 extraction ratio was also greater in the Hct 30 and Hct 20 groups than in the Hct 40 group (Hct 30, 73.0 +/- 13.9%; Hct 20, 70.1 +/- 9.6%; Hct 40, 57.1 +/- 11.5%; P < 0.05). In the conditions of our study, moderate hemodilution was associated with an improvement of the O2 extraction capabilities of the body, probably related to the reduction in blood viscosity.

Background: Neonatal hyperbilirubinemia is one of the commonest problems in newborn. It can be due to different etiologies. Most often it is physiological jaundice. The main reasons for physiological jaundice is that in an infant the liver is not mature enough to handle the freely circulating bilirubin due to higher volume of short life erythrocytes in the circulation and low level of albumin. Early detection of neonatal jaundice is essential to prevent developing kernicterus as well as discharge the babies early. Albumin is synthesized by liver and helps in the transport of unconjugated bilirubin by binding to bilirubin it and thus making it nontoxic to the body. Low levels of albumin make bilirubin free and toxic to the body. Hence, this study was done to evaluate effectiveness of cord blood albumin as a predictor of neonatal Hyperbilirubinemia.Methods: 50 term healthy newborns were included in the study with the term babies of both genders from any mode of delivery, birth weight >2.5 kg, APGAR score more than 7 at 1st and 5th minutes of life and without Rh incapability. Cord blood albumin levels were measured. Blood test for bilirubin was done when required and baby was managed accordingly.Results: Out of the total 50 neonates enrolled, 7 belonged to group 1 (albumin <2.8 g/dl), 34 to group 2 (2.8-3.3 g/dl), and 9 to group 3 (>3.3 g/dl). Out of the total 7 neonates in group 1, 6 (85.71%) was icteric at 24-48 hours and 1 (14.29%) was icteric at >72 hours. All the 7 neonates developed Hyperbilirubinemia requiring phototherapy. 3 (42.86%) out the 7-neonate required phototherapy for more than 24 hours. Out of the total 34 neonates in group 2, 20 (58.82%) was icteric at >72 hours, 12 (35.29%) at 48-72 hours and 2 (5.88%) at 24-48 hours. Only 12 (35.29%) neonates had Hyperbilirubinemia requiring phototherapy. Out of the total 9 neonates in group 3, 1 was icteric at 48 - 72 hours and 8 was icteric at >72 hours. But only 2 had Hyperbilirubinemia requiring phototherapy.Conclusions: Cord blood albumin is an effective way to predict neonatal Hyperbilirubinemia in term healthy infants.

<b>Background:</b> Acute appendicitis is the most common cause of acute abdomen. Delay in diagnosis increases the mortality and morbidity. <br><b>Aim: </b>In this study, we aimed to investigate whether the body mass index is useful in diagnosis and whether the neutrophil /lymphocyte and platelet/lymphocyte ratios can help in determining the inflammation level of acute appendicitis. <br><b>Meterial and Methods:</b> Cases of appendectomy performed between June 2012 and December 2018 in our clinic were analyzed retrospectively. Based on the pathology results of the cases included in the study, 4 groups were formed, i.e.: Group 1 (initial stage), Group 2 (catarrhal stage), Group 3 (phlegmonous-gangrenous stage) and Group 4 (perforation). The study compared age, body mass index, leukocyte values, red cell distribution width (RDW), neutrophil/lymphocyte ratio (NLR), platelet /lymphocyte ratio (PLR), and mean platelet volume (MPV) between groups. <br><b> Results:</b> 828 cases were included in the study. When compared between groups, the values of Group 3 and Group 4 were higher than those of Group 1 and Group 2 for PLR and NLR. There was no difference in RDW and MPV values in the blood. When Body Mass Index (BMI) was compared between groups, it was found to be significantly higher with increasing histopathological stage. <br><b>Conclusion:</b> In acute appendicitis, the blood leukocyte value, elevated PLR and NLR are helpful in diagnosis. We aimed to emphasize that the diagnosis of acute appendicitis is delayed in patients with a BMI above 30 and/or at age of over 40 years, with the perforation rate being determined more frequently.
