Mortellaro’s disease affects up to 25% of Russia's cattle, which causes significant economic damage to dairy products. The indicators of the therapeutic efficacy of existing drugs vary, and obsolete agents and schemes are used for treatment. A drug was developed and tested using the technology of liposomal silver nanoparticles (Ag) for treatment of Mortellaro’s disease in dairy cows. By comparison and grouping method, the effectiveness of 5 drug samples at different stages of development of infectious and pathological processes in 5 experimental groups of cows was compared with 2 control groups: Group 1 received no treatment, Group 2 was treated with Solka Hoofgel. It was established that sample 2 of the developed preparation with Ag content of 15 ml showed 92-96% of the therapeutic efficacy in the treatment of Mortellaro’s disease, which is higher than that of the analog preparation by 25%. The drug provides the appearance of granulation tissue in the affected areas as early as the fifth day after application to the damaged surface of the interdigital space and the epithelization of the damaged areas after 7 days of treatment.

Background: We aimed prospectively investigate the laboratory and electrocardiographic parameters (hearth rate, QRS, QT, QTc, Tpe, Tpe/QTc, arrhythmia prevalance) in patients with graves disease before and after antithyroid therapy. Methods: 71 patients (48 female, 23 male), age between 18-50 (mean±SD: 36.48±12.20 ) with GD were included into the study. Patients treated with antithyroid therapy (thionamids and/or surgical therapy) to maintain euthyroid status. Patients were examined in terms of electrocardiographic parameters before and after the treatment. Results: Mean TSH, free thyroxin (fT4) and tri-iodothyrionine (fT3) levels of all patients were 0.005±0.21, 3.27± 1.81, 11.42±7.44, respectively. While 9 patients (group 2) underwent surgical therapy, had suspicious of malignant nodule or large goiter and unresponsiveness to medical treatment; the other patients (n=62, group 1) were treated with medical therapy. Patients with surgical therapy had more increased serum fT4 (p=0.045), anti-thyroglobulin value (p=0.018) and more severe graves orbitopathy (n=0.051) before treatment when compared to medical therapy group. Baseline Tpe duration and baseline Tpe/QTc ratio and frequency of supraventricular ectopic beats were found to be significantly higher in group 2 when compared to group 1 (p=0.00, p=0.005). Otherwise baseline mean heart rate, QRS duration, QTc values of both groups were similar. Although the patients became their euthyroid status, group 2 patients had still suffered from more sustained supraventricular ectopics beats than group 1. Conclusion: Distinct from medical treatment group, surgical treatment group with euthyroidism at least 3 months had still suffered from an arrhythmia (Tpe, Tpe/QTc, supraventricular and ventricular ectopic beats).

AbstractAbdominal angiostrongyliasis (AA) is caused by Angiostrongylus costaricensis, which inhabits mesenteric arteries. There is no drug treatment for AA, and since intestinal infarction due to thrombi is one of the main complications of the disease, the use of anticoagulants may be a treatment option. Thus, we aimed to assess the effect of high doses of enoxaparin on the prevention of ischaemic intestinal lesions and on the survival of mice infected with A. costaricensis. Twenty-four mice were infected with L3 of A. costaricensis and divided equally into two groups: Group 1, control treated with placebo, and Group 2, treated daily with enoxaparin (2.5 mg/kg) for 50 days. All mice were subjected to necropsy and histological analysis. The results from gross and microscopic assessments showed no variation in the prevalence of lesions between the groups. An analysis was also performed among survivors and non-survivors, showing that animals that died often presented lesions, such as granulation tissue in the serosa, and intestinal infarction and adhesion. The mortality rate did not vary between the enoxaparin-treated and control groups. Thus, we showed that high doses of enoxaparin have no protective effect against AA, as the survival rates and lesions of mice did not vary between the treated and control groups. Considering that the use of prophylactic doses was also shown to be ineffective in a previous study, we do not recommend the use of enoxaparin for AA treatment.

Introduction: Kawasaki disease (KD), which is the most common multisystem vasculitis with unknown causes in childhood, causes coronary artery lesions (CALs). Treatment with a high dose of intravenous immunoglobulin (IVIG), plus steroids if needed, is the most effective therapy for the acute phase of KD. However, there are some very severe cases who need several times additional treatments and are at risk for CALs. In Japan, there are some scoring systems that initially predict IVIG-resistant patients. However, the problem is that these scoring systems fail in multiethnic populations. The aim of this study is to find universal biomarkers that predict treatment-resistant cases of KD. Methods: The subject was 276 KD patients, including Group 1 (n=214) who needed only 1 st line treatment, Group 2 (n=48) who needed 2 nd line treatment, Group 3 (n=14) who needed 3 rd line treatment or more. Tenascin C (TN-C), Pentraxin 3 (PTX3) and Procalcitonin (PCT) values, which were selected by systematic review, were measured before initial treatment in each group. Results: TN-C; 99.8±41.05 ng/ml in Group 1, 118.0±71.4 ng/ml in Group 2 and 183.0±25.0 ng/ml in Group 3. The TN-C level of Group 3 was significantly higher than that of all the others (p<0.01). The cutoff value for distinguishing Group 3 was 142.0 ng/ml (Area under the Curve (AUC)=0.81). PTX3; 16.2±9.0 ng/ml in Group 1, 31.4±19.7 ng/ml in Group 2 and 58.0±33.0 ng/ml in Group 3. The PTX3 level of Group 3 was significantly higher than that of all the others (p<0.01). The cutoff value for distinguishing Group 3 was 35.1 ng/ml (AUC=0.86). PCT; 0.79±0.77 ng/ml in Group 1, 2.55±3.01 ng/ml in Group 2 and 4.15±4.49 ng/ml in Group 3. The PCT level of Group 3 was significantly higher than that of all the others (p<0.01). The cutoff value for distinguishing Group 3 was 2.55 ng/ml (AUC=0.88). When those three biomarkers combined, Group 3 can be predicted with the sensitivity 79%, the specificity 96%, the positive predictive value 50% and the negative predictive value 99%. Conclusions: It may be possible to predict treatment-resistant KD cases with high sensitivity and specificity by combining the measurement from the universal biomarkers, TN-C, PTX3 and PCT, before initial treatment.

AbstractThe study compared the impact of feeding different energy supplements (barley, molassed sugar beet and fat) prior to calving and the effects of feeding supplemental fat post-partum, on subsequent production and reproductive efficiency of dairy cows. Forty-eight multiparous Holstein-Friesian dairy cows were assigned to one of two groups, six weeks prior to expected calving date and fed a grass based total mixed ration according to ME requirements for late gestation. Group 1 was supplemented with barley (B) or molassed sugar beet feed (SB) prior to calving and was then given a high starch lactation ration. Group 2 was supplemented with either fat (F) or no supplement (C) pre partum, and was then given a similar lactation ration as Group 1 but supplemented with fat. Lactation rations were fed through to week-20 post partum and the cows were monitored during this period. Milk yield (P<0.002) and milkfat (P<0.02) production were higher and milk protein concentration (P<0.001) was lower in Group 2. The number of days to first rise in progesterone following parturition was greater (P<0.01) in Group 2. Due to the design of the study, effects of prepartum supplementation were only evaluated within each lactation ration group. Conception rate to first service was higher (P<0.001) for B than SB supplemented cows in Group 1 and higher (P<0.02) for F than C supplemented cows in Group 2. Services per conception were lower (P=0.06) for B than SB supplemented cows in Group 1 and lower (P<0.05) for F than C supplemented cows in Group 2. Overall pregnancy rates and days open were not significantly different between the groups. The data shows that pre-partum nutrition had an important role in determining subsequent fertility. Despite having negative effects early post partum, supplementing with fat did not affect overall reproductive performance but it did improve milk production.

Objectives and designThis trial evaluated the effect of bandaging of acute painful ulcerative bovine digital dermatitis (DD) lesion (stage M2) in dairy cows, tested using two different topical treatments.DesignRandomised clinical trial.SettingThis study was conducted using Holstein-Friesian cows ranging in age from heifers to fourth lactation in a single dairy herd and diagnosed with acute ulcerative DD lesions (stage M2) on the first examination (week 0). Cows were randomly assigned into either a non-bandaged or bandaged group across two treatment conditions: topical chlortetracycline spray (CTC) and Intra Hoof-Fit Gel (IHF). Lesions received standardised bandaging and treatment on a weekly basis. Unhealed lesions could receive up to five repeated treatments, at weekly intervals, within a four-week period. Both M-stage and locomotion were also evaluated and scored weekly. Cows with healthily formed skin (stage M0) were deemed healed and subsequently released from the study.ResultsIn total, 163 M2 lesions were diagnosed at week 0. Bandaged M2 lesions had a significantly higher probability of cure than non-bandaged lesions regardless of treatment type (HR: 4.1; P<0.001; 95 per cent CI: 2.5 to 6.8). Most healing occurred within the first three weeks of trial. Furthermore, bandaged lesions (group 2 and group 4) were significantly less likely to progress into the chronic hyperkeratotic or proliferative stage (M4) than non-bandaged lesions in group 1 and group 3 (HR: 0.10; P<0.001; 95 per cent CI: 0.04 to 0.22). Out of concern for the cow’s wellbeing, this study investigated the effects of bandaging on locomotion. Bandaging had no effect on locomotion for either cows treated with CTC (group 1: median Sprecher score, 2; IQR=1–2; group 2: median Sprecher score, 2; IQR=1–3; P=0.3) or IHF (group 3: median Sprecher score, 2; IQR=1–2; group 4: median Sprecher score, 2; IQR=1–3; P=0.3).

Parturient paresis and subclinical hypocalcemia are frequent metabolic disorders in dairy cows postpartum. The aim of this study was to determine the effect of postpartum partial milking in the first two milkings on blood serum calcium concentration in dairy cows. Twenty multiparous Holstein dairy cows were randomized into two groups. Cows of group 1 (n = 10) were partially milked at the first and second milking postpartum. Cows of group 2 (n = 10) were completely milked. Blood samples were collected from all animals 5&ndash;7 days before calving, within 30 min after calving, and 4, 8, 12, 16, 20, 24, 28, and 32 h after calving for determination of serum calcium (Ca), phosphorus (P), and magnesium (Mg) concentrations. Colostrum production was registered and sampled in the first and second milking. Concentration of Ca in colostrum was determined by atomic absorption spectrophotometry. Serum Ca and P concentrations decreased in both groups after parturition (P &lt; 0.05) and remained low during 32 h postpartum with no difference observed between groups (P &gt; 0.05). Serum concentrations of Mg were stable in all samples and no statistical difference was observed between groups (P &gt; 0.05). Colostrum production was higher in completely milked cows only in the first postpartum milking (P &lt; 0.05), but there was no difference between groups at the second milking. Total Ca secretion in colostrum was higher in the complete milking group at the first and second postpartum milking. Colostrum Ca secretion increased at the second milking with respect to the first one in both groups (P &lt; 0.05). There was no correlation between serum Ca and colostrum Ca (P &gt; 0.05). In this study, the partial milking of colostrum in the first and second milking postpartum did not prevent subclinical hypocalcemia in dairy cows. &nbsp;

Abstract. The effect of growth hormone (hGH) on the hypothalamic-pituitary-thyroid function was studied in patients with pituitary dwarfism. Twenty-six patients were given KABI hGH, 0.5 U/kg/week, for a period of 4—18 months. Three groups of patients were identified according to their T4 levels before and during the treatment. Group 1: T4 levels were initially normal and stayed in the normal range throughout a course of treatment. Group 2: T4 levels were initially normal but dropped to the subnormal range after hGH. Group 3: T4 levels were initially subnormal and decreased further after hGH. Changes in T4 levels after hGH in groups 2 and 3 were accompanied by a decrease in plasma T3RSU without concomitant decrease in plasma T3. Clinically, most of them lacked symptoms and signs of hypothyroidism and exhibited a good growth response to hGH. Plasma TSH response to TRH in these patients revealed a sustained delayed pattern, which was suggestive of hypothalamic hypothyroidism. This pattern of TSH response to TRH became further exaggerated after hGH therapy. In contrast, TSH response to TRH among patients in group 1 was normal and was not influenced by hGH. Administration of 4.0 U of KABI hGH daily for 21 consecutive days to 3 patients resulted in a shortened half-life of T4 and inversely prolonged that of T3. These results suggest that various degrees of TRH deficiency exist among patients with idiopathic pituitary dwarfism. Therapy with hGH discloses a mild TRH deficiency by accelerating the half-life of T4. This also causes a further drop in the T4 levels in those with marked TRH deficiency. The development of clinical hypothyroidism is not so obvious in these patients because of inverse delay in half-life of T3 by hGH.

Objective To investigate the eruption pattern of the cleft-side canine regarding its pre-eruption position relative to the cleft in bone-grafted (BG) and nongrafted (NonBG) patients with cleft lip and palate. Methods Fifty-three patients with cleft lip and palate (21 BG, 32 NonBG) were examined by panoramic radiography and posteroanterior cephalography taken before and after canine eruption. Subjects were categorized into BG, NonBG, and control groups. Canines at the pre-eruption stage were categorized as close to (group 1) or distant from (group 2) the cleft area. The canine angle and its change between the two stages were evaluated. Results No significant differences were noted between the initial canine angle of the BG and NonBG groups. Although canines in the BG group erupted without a significant change in angle, the canine angle increased significantly (p < .0001) in the NonBG and control groups. In group 1, a greater change in canine angle was noted in the NonBG (p < .05) and control (p < .01) groups than in the BG group. In group 2, no significant difference was noted among the three groups. Conclusions In BG patients, a canine located near the cleft appears to erupt at the same angle as it had before grafting. However, in NonBG patients, it erupts more vertically, guided by cortical bone. For canines distant from the cleft area, there is no significant difference in the change in angulation between NonBG and BG patients.

ABSTRACT Objectives: The objective of the following study is to evaluate the interaction between the resin materials used in immediate dentin sealing (IDS) techniques and impression materials with two different techniques to eliminate the oxygen-inhibition layer. Materials and Methods: The occlusal dentin surface of 35 human molars was exposed. The teeth were used in two Groups: Group 1 – Impression with Express XT; Group 2 – Impression with Impregum. Groups 1 and 2 were divided into 14 subgroups: Groups 1a and 2a – Control groups; 1b and 2b – IDS with Clearfil SE Bond (CSE); 1c and 2c – IDS with CSE + additional polymerization with glycerin jelly; 1d and 2d – IDS with CSE + alcohol; 1e and 2e – IDS with CSE and Protect Liner F (PLF); 1f and 2f – IDS with CSE and PLF + additional polymerization with glycerin jelly; and 1g and 2g – IDS with CSE and PLF + alcohol. Five teeth were used in each experimental group, and the tooth surface was photographed using a digital camera. Results: Small quantity of unpolymerized impression material remained attached to the CSE or to the PLF in Groups 1b and 1e. Groups 1c and 1d prevented the interaction. Small quantity of polymerized impression material remained attached to the CSE or to the PLF for Groups 2b and 2e. The same interaction was observed for Groups 2c and 2d. For Groups 2c and 2f, no interactions were observed. Conclusion: Resin materials interacted with impression materials. The application of glycerin jelly and alcohol prevented the interaction of CSE with Express XT and PLF with Impregum; however, these treatments were not completely effective in preventing the interaction of CSE with Impregum and PLF with Express XT.

Objective. To investigate the effects of topical and subconjunctival tigecycline on the prevention of corneal neovascularization.Materials and Methods. Following chemical burn, thirty-two rats were treated daily with topical instillation of 1 mg/mL tigecycline (group 1) or subconjunctival instillation of 1 mg/mL tigecycline (group 3) for 7 days. Control rats received topical (group 2) or subconjunctival (group 4) 0.9% saline. Digital photographs of the cornea were taken on the eighth day after treatment and analyzed to determine the percentage area of the cornea covered by neovascularization. Corneal sections were analyzed histopathologically.Results. The median percentages of corneal neovascularization in groups 1 and 3 were 48% (95% confidence interval (CI), 44.2–55.8%) and 33.5% (95% CI, 26.6–39.2%), respectively. The median percentages of corneal neovascularization of groups 1 and 3 were significantly lower than that of the control group (P=0.03andP<0.001, resp.). Histologic examination of samples from groups 1 and 3 showed lower vascularity than that of control groups.Conclusion. Topical and subconjunctival administration of tigecycline seems to be showing promising therapeutic effects on the prevention of corneal neovascularization. Furthermore, subconjunctival administration of tigecycline is more potent than topical administration in the inhibition of corneal neovascularization.
