Summary. Aim. Comparison of methods for diagnosis of hepatic encephalopathy in patients with cirrhosis. Matherials and Methods. We observed 95 patients with LC who were hospitalized from 2018 to 2020 in the Department of Anesthesiology and Intensive Care, Surgical and Gastroenterological Departments of the Transcarpathian Regional Clinical Hospital. Andriy Novak (Uzhhorod). Neurological status, state of mental and cognitive functions in patients with LC were assessed before and after the course of therapy with psychometric testing, as well as electroencephalographic (EEG) study. The severity of LE was determined by West-Haven criteria. Results. Signs of LE were not diagnosed in 8.4 % of patients with LC. In 13.8 % of patients found a latent form of LE. This was most often observed in the III century. (in 25.2 % of patients), LE II. diagnosed in 22.1 % of patients with LE and Art. — in 17.9 % of examined patients, and in 12.6 % of examined — LE IV. In patients with LC, alpha waves on the EEG are most often registered in the latent form of LE, and with the increase of clinical signs of LE there is a decrease in the frequency of alpha waves, instead of pathological delta and theta waves. Conclusions. According to the MMSE scale, the highest scores are observed in patients of group I (29.9 ± 3.4). The most pronounced disorders of intelligence were determined in patients with LC of group III from the IV century. LE (15.1 ± 3.3). The level of personal anxiety in patients with LC was higher than normal in patients with LE II-IV centuries. surveyed groups with maximum values in group III (55.5 ± 8.2). At patients with LC the expressed cognitive frustration are observed. Signs of LE were not diagnosed in 8.4 % of patients with LC. In 13.8 % of patients found a latent form of LE. This is most often observed in the III century. (in 25.2 % of patients), LE II. diagnosed in 22.1 % of patients with LE and Art. — in 17.9 % of examined patients, and in 12.6 % of examined — LE IV.

We have determined the sites of action of endothelin-1 (ET) in the lamb pulmonary circulation. The influence of cyclooxygenase inhibition and baseline vasomotor tone on ET effects was also studied. Lungs of 14 lambs (6-9 wk of age, 12.1 +/- 0.6 kg body wt) were isolated and perfused with blood. Group I lungs (n = 5) were untreated, group II lungs (n = 5) were treated with indomethacin to inhibit cyclooxygenase, and group III lungs (n = 4) were treated with indomethacin and a thromboxane A2 analogue, U-46619, to elevate vasomotor tone. All lungs were perfused with constant flow in zone 3, with left atrial and airway pressures being 8 and 6 cmH2O, respectively. We measured pulmonary arterial pressure and, by the micropuncture servo-null method, pressures in 20- to 50-microns diameter subpleural venules, both before and after each dose of ET was infused (50, 100, 250, and 500 ng/kg). Group I lungs, with high baseline vasomotor tone, exhibited a biphasic response to ET; 50-100 ng/kg of ET dilated both arteries and veins, whereas 500 ng/kg of ET constricted both arteries and veins. In group II lungs with low vasomotor tone, all doses of ET caused constriction of arteries only. In group III lungs (indomethacin treated with elevated vasomotor tone), 50-100 ng/kg of ET caused dilation of arteries and veins, whereas 500 ng/kg of ET induced constriction, this time only in arteries. We conclude that ET has both dilator and constrictor effects in arteries and veins of isolated, perfused lamb lungs. ET-induced arterial and venous dilation is dependent on initial vasomotor tone but not on cyclooxygenase metabolites.(ABSTRACT TRUNCATED AT 250 WORDS)

Background: The role of fluoride in preventing tooth decay both for children and adult has been acknowledged internationally. There are several types of fluoride modalities either topically or systemic way. In Indonesia the modalities used to apply are fluoride tablet, fluocol solution and fluoride containing toothpaste. The purpose of this research is to find the effectiveness of fluoride modalities.Method: The study design was quasy experimental with 40 extracted teeth (Premolar teeth). The teeth divided into four groups D group I soaked on tablet fluor, Group II ; soaked on fluocol solution, Group III soaked on fluoride tooth paste and group IV soaked on Mill J (Aquadest/ Control solution). Fluoride concentration before and after soaking was determined using Spectrophotometer UV-Vis. Fluoride absorption was determined by the reduction of fluoride concentration after soaking.Result: Research result shown that the highest fluoride absorption was on soaking in fluoride tablet, followed by soaking on fluocol and tooth paste (mean fluoride absorption was 0,32; 0,08 and 0,04 ppm). Anova test shown significance level was 0,000.Conclusion: there were a significance of fluoride absorption on soaking in tablet fluoride, fluocol solution and toothpaste. The mechanism of fluoride regimens shown different fluoride absorption.

The aim of the 21 day toxicity study was to evaluate the pathomorphological effect of flunixin meglumine in layer chicks. The chicks of Group I were kept as control while groups II, III and IV were fed with diet containing flunixin meglumine @ 10 ppm, 25 ppm and 50 ppm respectively for 21 days. Clinical signs viz. anorexia, dullness,lethargy, lameness and uneven growth were noticed in chicks of treatment groups III and IV only. Maximum mortality was observed in group IV (12%) followed by group III (4%). A dose dependant reduction in body weight was observed in all the treatment groups. The mean values of Kidney: Body weight ratio was significantly increased in group IV. The plasma uric acid, creatinine and BUN values were significantly increased in group III whereas increase in group IV was highly significant. Grossly, there was deposition of chalky white urates on serosal surface of kidney, heart and liver in chicks of group IV which died during experiment. Microscopically, lesions were characterized by varying degrees of congestion, haemorrhages, degeneration, necrosis and deposition of urate crystals in visceral organs of group III and group IV chicks. The intensity and distribution of pathological lesions were more severe in chicks of group IV, followed by chicks of group III. The overall lesions gave an impression that flunixin meglumine was nephrotoxic in nature.

Form rotation, figure directionality, and figure-ground discrimination were evaluated before and after 10 days of vestibular or aerobic exercises for 30 boys (7 to 12 yr.) who showed problems in learning, reading, and inattention. Eight subjects had normal vestibulo-ocular reflex (VOR) responses as determined by caloric and rotational testing. They were assigned to a vestibular program (Control Group I). The 22 subjects with abnormal VOR test responses were randomly assigned to either aerobic exercises (Experimental Group II) or a vestibular program (Experimental Group III). Spatial perceptual test scores varied widely, with the majority performing below age-expected norms but no significant differences on vestibular status appeared. Postexercise, only subjects completing the vestibular program made significant gains: Experimental Group III (abnormal VOR) made significant gains in accuracy and normal test responses compared to the other groups, and Control Group I made significantly greater gains in speed of spatial perceptual processing. For boys with problems in learning, reading, inattention, and vestibular function, a vestibular exercise program complementing a traditional or special educational program may enhance the spatial perceptual skills needed for reading.

Objective: The study aimed to compare eye outcomes between the standard and accelerated corneal cross-linking (CXL) protocols over a 1-year follow-up, and assess whether the accelerated protocols are non-inferior to the standard. Methods: A retrospective cohort study including patients older than 18 years diagnosed with progressive keratoconus who underwent a CXL procedure. The primary outcome was defined as an increase of more than 1.5 diopter (D) in Kmax. The analysis included intra- and inter-group comparisons assessing differences in eye characteristics before and 12 months after the procedure. Furthermore, we assessed whether the accelerated procedures were non-inferior to the standard regarding Kmax change after 12 months. Results: Eighty-four patients included in the study of which 23, 37 and 23 underwent the standard CXL (group I), 10-min. (group II) and the 3-min. (group III) accelerated procedures, respectively. Intra-group comparison before and after 12 months of mean Ksteep and anterior corneal astigmatism showed significant improvement only for group I (–0.3D decrease for both). Inter-group comparison showed better results after 12 months for group I (–0.9 ± 1.2) compared to group III (0.1 ± 0.8) in Ksteep, Kmean (–0.5+1. vs 0.1+0.7, respectively) and anterior astigmatism (–0.5 + 0.9 vs 0.3+1.1, respectively). We could not declare that the accelerated CXLs are non-inferior to the standard ( p-value = 0.11 and 0.15). Conclusion: The standard CXL showed better results for keratometry and astigmatism in comparison with the accelerated. Therefore, the wide use of the accelerated CXL should be considered and reviewed for longer follow-up time and larger sample size in focus on the visual acuity parameters.

This article presents the results of a randomized clinical trial, designed to compare the efficacy and therapeutic profiles of YpozaneTM (osaterone acetate—OA) or SuprelorinTM (deslorelin acetate—DA) in male dogs with clinical signs of benign prostate hyperplasia (BPH). Forty-five intact male dogs were used in the study. The Group I (negative control) included 10 healthy dogs, the Group II (positive control) included 10 dogs with confirmed BPH and no treatment, whereas Group III and IV consisted of dogs with BPH and treated either with DA (15 dogs) or OA (10 dogs). The clinical response, testosterone and estradiol levels, hematology, biochemistry, and adverse effects incidence were evaluated. Both OA and DA proved to be effective for BPH treatment in dogs, as they allowed for the clinical remission in all treated dogs. The complete alleviation of BPH symptoms was noticed sooner with the use of OA (in 80% of dogs from day 7) compared to DA (in 40% of dogs within the first 21 days). The recurrence of clinical signs related to BPH was observed from week 24 in dogs treated with OA, whereas no relapse was noticed in dogs treated with DA at the end of the 36 weeks of the observation period. In 5 dogs (33%) treated with DA, a flare-up effect (increase in the clinical signs associated with BPH) was noticed on day 7. Despite individual differences in the clinical action, both medications were effective and safe options for the treatment of symptoms related to BPH in dogs.

Clearance and intratubular microinjection studies were performed in rats during extracellular volume expansion before and after furosemide administration to evaluate renal tubular transport of glucose. Three groups of animals were studied: group I, intact rats; group II, acutely thyroparathyroidectomized rats; and group III, thyroparathyroidectomized rats receiving parathyroid extract after a control period. In all groups furosemide caused a significant increase in the urinary flow rate and sodium excretion. There was no significant change in filtered glucose and glucose excretion. After early distal tubular injections of [14C]glucose, recovery was complete both before and after furosemide infusion. Furosemide had no effect on [14C]glucose recovery after the late proximal injection. These results indicate that furosemide has no effect on the renal handling of glucose in normoglycemic rats. There is no evidence for glucose reabsorption in the nephronal segments distal to the early distal tubular segment in this experimental state. Our data suggest, but do not prove, that no glucose is transported by the rat nephron beyond the pars recta during normoglycemia.

To determine the importance of the fibrinolytic system in renal transplantation on the one hand, and to establish a correlation between possible endothelial damage due to treatment of the renal graft and fibrinolytic parameters on the other, dogs were divided in six groups. Group I dogs were subjected to anesthesia only. Group II was sham operated. In group III, kidneys were perfused with the supernatant of either autologous or homologous cryo-precipitated plasma, and in group IV with albumin. In group V kidneys were cold stored. This was followed by autotransplantation. In group VI kidneys were perfused with albumin and allografted. Before and after transplantation, total plasma plasminogen (pro) activator activities in systemic and renal circulations were measured on fibrin plates after the addition of dextran sulfate and flufenamate to euglobulin fractions. Vascular activator (VA) was measured by adding Cl-inactivator. There was no marked difference between groups III, IV and VI. In comparing, however, group V with any of the perfused groups, an overall higher fibrinolytic activity was recorded both for intrinsic activators (p<.001) and VA (p<.001). in group I a significant drop in both activities (p<.01 -<.02) could be directly related to the duration of anesthesia with recovery within 24 hours. This pattern, though highly accentuated, revealed itself in all the other groups studied, with VA temporarily reaching zero-levels in the renal circulation in group VI. This data indicates the participation of the fibrinolytic system, in particular of the VA, in determining the fate of renal grafts.

Objective. Evaluate if different bleeding patterns associated with the use of the levonorgestrel intrauterine system (LNG-IUS) are associated with different uterine and endometrial vascularization patterns, as evidenced by ultrasound power Doppler analysis.Methodology. A longitudinal study, with each subject acting as its own control was conducted between January 2010 and December 2012. Healthy volunteers with a history of heavy but cyclic and regular menstrual cycles were enrolled in the study. Ultrasonographic examination was performed before and after six months of LNG-IUS placement: uterine volume, endometrial thickness, and subendometrial and myometrial Doppler blood flow patterns have been evaluated.Results. A total of 32 women were enrolled out of 186 initially screened. At six months of follow-up, all subjects showed a reduction in menstrual blood loss; for analysis, they were retrospectively divided into 3 groups: normal cycling women (Group I), amenorrheic women (Group II), and women with prolonged bleedings (Group III). Intergroup analysis documented a statistically significant difference in endometrial thickness among the three groups; in addition, mean pulsatility index (PI) and resistance index (RI) in the spiral arteries were significantly lower in Group I and Group III compared to Group II. This difference persisted also when comparing—within subjects of Group III—mean PI and RI mean values before and after insertion.Conclusions. The LNG-IUS not only altered endometrial thickness, but—in women with prolonged bleedings—also significantly changed uterine artery blood flow. Further studies are needed to confirm these results and enable gynecologists to properly counsel women, improving initial continuation rates.

ABSTRACT The concentration of sex hormones and their binding in the plasma were measured in male patients (20–40 years old), who weighed 140–170 % (I), 170–200 % (II) and > 200 % (III) of their ideal weight. Correlated to body weight, there is a reduction in the total concentration of testosterone, which, in the very obese patients, amounts to 41 % (in group I: 85 % in group II: 68 % P < 0.001) of that found in an age-matched healthy control group of subjects of "normal" body weight (90–115 % of the ideal body weight; n: 20). Androstenedione values show only a trend downwards (from 0.94 to 0.72 ng/ml plasma), while the oestrogen values increase significantly; oestrone increases by a factor of 1.09 (I), 1.43 (II; P < 0.001) and 1.69 (III; P < 0.001) and oestradiol by 1.13, 1.43 P < 0.001) and 1.76 (P < 0.001), respectively. Despite the fall in testosterone there are no clinical signs of hypogonadism, as SHBG (from 5.1 ± 0.8 in the controls to 2.4 ± 0.6 ×10−8 Mol/l in the very obese patients of group III) and the protein-bound fraction of testosterone also decrease. As a result the concentration of free testosterone remains constant (120 pg/ml), except in the very obese (93 pg/ml). Because of the different affinity of the binding proteins for testosterone and oestradiol the ratio of free oestradiol: free testosterone shifts less strongly in favour of the feminizing hormone (11.1 × 10−3 in group III as compared to 4.1 × 10−3 in the controls), than is suggested by the total hormone concentrations. A disturbance in the gonadal function of the pituitary gland or the testes is not present, since the concentration of LH is normal and the testicular response to HCG in very obese patients adequate (increase of testosterone by a factor of 3.11 as compared to 2.23 in the controls). The cause of the decrease in testosterone and SHBG is unknown, while the increase of plasma oestrogens is likely to be due to the increased conversion of androgens to oestrogens in the adipose tissue, which clearly plays an important role for plasma concentrations of sex hormones in obese patients.
