The Timed Up and Go (TUG) test quantifies physical mobility by measuring the total performance time. In this study, we quantified the single TUG subcomponents and, for the first time, explored the effects of gait cycle and pelvis asymmetries on them. Transfemoral (TF) and transtibial (TT) amputees were compared with a control group. A single wearable inertial sensor, applied to the back, captured kinematic data from the body and pelvis during the 10-m walk test and the TUG test. From these data, two categories of symmetry indexes (SI) were computed: One SI captured the differences between the antero-posterior accelerations of the two sides during the gait cycle, while another set of SI quantified the symmetry over the three-dimensional pelvis motions. Moreover, the total time of the TUG test, the time of each subcomponent, and the velocity of the turning subcomponents were measured. Only the TF amputees showed significant reductions in each SI category when compared to the controls. During the TUG test, the TF group showed a longer duration and velocity reduction mainly over the turning subtasks. However, for all the amputees there were significant correlations between the level of asymmetries and the velocity during the turning tasks. Overall, gait cycle and pelvis asymmetries had a specific detrimental effect on the turning performance instead of on linear walking.

Objective: Potash known as potassium carbonate (K2CO3) is a mixture of salt with other components, including impurities which coexist in mineral and salt is highly consumed in various forms by pregnant women. The aim of this research is to determine the effect of potash on the weight index of pregnant Wistar rats. Methods: A total of 25 albino Wistar rat with weights ranging from 180 to 300 g were used and allocated into five groups of five animals each (four females and one male) designated as Groups A, B, C, D, and E. The experimental Groups B, C, D, and E were administered through oral route different doses of potash of 300 mg/kg, 600 mg/kg, 900 mg/kg, and 1200 mg/kg, respectively, after pregnancy was detected by checking for mucus plug in the vagina. Group A served as the control group and was administered distilled water only. The animals were allowed for 1 week for acclimatization under normal temperature (270–300°C), which they were being fed with normal feed (grower’s mash) and water ad libitum for 1 week. Results: The result showed a significant (p˂0.05) reduction in weight with the highest level seen with the 1200 mg/kg group when compared to the control. Conclusion: Therefore, the effect of potash alters the physical activity and decreases weight, by implication may induce growth retardation of the Wistar rats which is not healthy for a pregnant animal.

The Central Nervous System

Tributyltin (TBT) compounds have been used as anti-fouling agents and the central nervous system is one of its target organs. TBT-induced modulations of neurotransmitters in the brains of adult mice have been reported. However, little is known about the developmental neurotoxicity of TBT. In this study, we evaluated the effects of TBT on neurotransmitters and their metabolites in discrete brain regions of female ICR mice and their offspring. Pregnant ICR mice were exposed to TBT chloride at concentrations of 0, 15 or 50 ppm in water or 125 ppm in food. Male offspring were sacrificed at one, two and three weeks after birth. The concentrations of norepinephrine, dopamine (DA), dihydoxyphenylacetic acid, homovanillic acid (HVA), serotonin (5-HT), and 5-hydroxyindoleacetic acid (5-HIAA) were determined in different brain regions by HPLC. All offspring from the 125 ppm group died immediately after birth. A significant decrease in the body weight of the TBT-treated F1 groups compared to the control group was observed in the first week. Significant increases compared to the controls were observed for the DA concentration in the striatum of the 50 ppm F1 group, and for the HVA concentration in the cerebrum and the 5-HT concentration in the medulla oblongata of the 15 and 50 ppm F1 groups in the third week. At three weeks of age, the neurotransmitters and their metabolites may be useful indexes for developmental neurotoxicity. For the dams, a significant decrease in the 5-HT concentration was observed in the cerebellum, medulla, midbrain and striatum of the 125 ppm group compared to the control group. A significant decrease in the 5-HIAA concentration was also observed in the cerebellum, midbrain and striatum of the dams in the 125 ppm group compared to the control. TBT may induce a decrease in the synthesis of 5-HT in the dams. The discrepancy between dams and offspring may be due to several factors such as age, dose, route, sex and pregnancy.

The aim of this study was to determine the effect of supplement «Press-Acid» on some parameters of mineral and protein metabolism and resistance of piglets. The study was done in condition «Meta» on two groups of piglets of the F-1 (BWхL) genotype. There were determined indexes of bacterial and lysocim activity of blood serum, calcium and phosphorus in piglets at the age of 21–30–45–75 days. Effect of supplement on the growth rate, morbidity and safety of pigs were revealed. We used hygienic, zootechnical, hematological, biochemical, immunological and statistical methods of analysis. The influence of «Press-Acid», which consist of formic, lactic, citric and fumaric acids, was established for the first time. The concentration of calcium in blood serum of experimental group of piglets were lower than in animals of control group. The level of phosphorus increased in blood serum of experimental animals on 11.83% (30 day), on 3.74% (45%), on 17.65% (75 day) respectively. Concentration of hemoglobin and the amount of erythrocytes increased on 11.8% and on 1.82% (30 day) in animals that feed the supplement. There were established the increase of viability of the pigs with gastro-intestinal diseases which were given the supplement in comparison with that, who did not feed it. Severity of diseases was determined using the Melenberg coefficient which did not higher than 1.2–2.4 score, it was lower on 6,0–9,3 unit than in control group. Using the supplement allowed to increase the intensity of growth of piglets by 3.7% (45 day) and 9.4% (75 day) respectively. Concentration of total protein, albumines and globulins increased on 8.66%, 9.90%, 7.3% respectively. The activity of alaninaminotransphaerasae in the blood serum of experimental animals were lower on 3.45% than in control piglets. Lysocym and bacterial activity of blood serum were higher in experimental group of piglets. Feeding piglets with addition supplement Press Acid promotes higher grow rates in experimental animals, that can be explained increases of oxidative-reducing processes in them organism. Feeding piglets with acidifier «Press-Acid», «Nifulin», zinc oxide, probiotics «Lactisan Complex» promotes growth energy, increase of morphological, biochemical and immunological parameters which indicates a higher level of oxidative reaction in the body. A low coefficient of Melenberg is recorded in the piglets at the age of 1 day. Safety was within 92.1–97.0%. That indicates a more successful elimination of complexes of protein, mineral substances, humoral protection in blood of experimental group of animals.

Effects of neem, betel leaf, devil’s tree, jute and turmeric against natural gastrointestinal nematodes in sheep and on some hematological parameters (TEC, Hb and PCV) and body weight were studied. Thirty (30) naturally parasitized sheep were randomly divided into six groups(A, B, C, D, E and F), each consisting of five sheep. Ten percent water extract of leaves of neem, betel leaf, devil’s tree and jute were administered orally to the sheep of group A, B, C and D, respectively. Sheep of group E was treated orally with 10% water extract of rhizome of turmeric. Sheep of group F was kept as infected control group. Fecal samples, hematological parameters and body weight were examined before treatment and on 7th, 14th, 21st and 28th day. A significant (p<0.01) reduction of EPG count was found following administration of neem (37.60-47.03%), betel leaf (6.43-14.00%), devil’s tree (3.04-11.04%), jute (0.50-5.26%) and turmeric (0.46-8.30) in sheep. The EPG count of the control group (F) were significantly (p<0.01) increased up to the last day of experimental period. After treatment with neem, betel leaf, devil’s tree, jute and turmeric total erythrocyte count (TEC), hemoglobin (Hb) content and packed cell volume (PCV) were increased significantly (p<0.01 and p<0.05) in sheep. The body weight was increased significantly (p<0.01 and p<0.05) in neem, betel leaf, devil’s tree, jute and turmeric treated sheep. On the other hand, body weight was decreased in untreated control group. The present study reveal that 10% water extract of neem was moderately effective and betel leaf, devil’s tree, jute and turmeric were relatively less effective against gastrointestinal nematodes in sheep.

Цель исследования - оценка возможности использования интегральных гематологических индексов для выбора оптимальной модели ушивания послеоперационных ран в эксперименте. Методика. Исследование проводили на 297 белых беспородных крысах-самцах массой 190-210 г, которые были разделены на 3 группы, по 99 крыс в каждой. Одна группа являлась контрольной, у второй группы крыс был смоделирован раневой процесс с натяжением брюшной стенки; у третьей группы животных - модель раневого процесса с применением трансплантата нанокомпозитного материала. Определяли следующие интегральные гематологические индексы: индекс Кребса; коэффициент Бредекка; лейкоцитарный индекс; индекс соотношения нейтрофилов и моноцитов; индекс соотношения лимфоцитов и моноцитов; индекс соотношения лимфоцитов и эозинофилов; коэффициент отношения альбуминов к глобулинам; оксипролиновый коэффициент. Результаты. Установлены статистически значимые колебания показателей интегральных гематологических индексов в динамике заживления послеоперационной раны у крыс. Заключение. На основе полученных результатов был сделан вывод, что особенности динамики интегральных гематологических индексов, выявленные на различных моделях раневого процесса, отражают неспецифические и специфические защитные реакции организма в целом, позволяют делать прогноз дальнейшего течения и исхода раневого процесса, а также обеспечивают возможность выбора оптимальной модели ушивания послеоперационной раны. The article presents results of predicting the wound healing process using integral hematological indexes. The aim of the study was to describe the dynamics of integral hematological indexes of wound healing process in rats to predict its outcome. The study included 297 white mongrel male rats weighing 190-210 g, which were divided into three groups, 99 rats in each. One group was a control group; in the second group, a wound healing process with abdominal wall tension was modeled; in the third group, a wound healing process with a graft was modeled. The following integrated hematological indexes were determined: Krebs index; Bredeck index; leukocyte index; neutrophil/monocyte ratio; lymphocyte/monocyte ratio; lymphocyte/eosinophil ratio; albumin/globulin ratio; and oxyproline coefficient. The study showed that changes in values of integral hematological indexes were mostly statistically and clinically significant. We concluded that changes in integral hematological indexes in different models of wound healing reflect nonspecific and specific protective responses of the body as a whole and allow to predict further course and outcome of the wound healing process.

AbstractHippocampal changes in epilepsy may manifest as hippocampal atrophy/sclerosis. A recent human study suggests that the demonstration of hippocampal volume loss is more reliable using quantitative evaluation methods. The aim of the present study was to obtain volumetric data in both epileptic and healthy dogs, to compare hippocampal volumes in both groups, and to compare subjective and volumetric assessment. Volumetric measurements of the hippocampi, lateral ventricles and hemispheria were performed in 31 epileptic and 15 control dogs. There was a positive association between the body weight and the hemispheric volume, as well as between the hemispheric volume and the ipsilateral hippocampal volume. There was no significant correlation between age and the volume of any measured brain structures. There was no statistically significant difference between the hippocampal volumes of the control group and the epileptic group. A statistically significant difference between the two groups for hippocampus/hemispherium ratio or hippocampal asymmetric ratio was not identified. An extrapolated hippocampal volume based on body weight was not possible in this study population.

This study was conducted to describe the kinematics of bodyroll and investigate whether bodyroll was propelled primarily by the turning effect of the fluid forces (external torque) or by the reaction effect due to the acceleration of the limbs. The performances of 11 competitive swimmers were recorded using two panning periscopes, and the three-dimensional movement of the subjects was reconstructed from digitized video recordings. The external torque acting on the whole body was determined as the first time-derivative of the angular momentum of the whole body. The reaction effect of limb acceleration was determined as the first time-derivative of the angular momenta of the limbs. Shoulder roll and hip roll angles changed synchronously with the stroke frequency but their amplitudes were substantially different, indicating that the bodyroll consisted of a roll of the entire torso and a twist of the torso. The overall contribution of the external torque was to propel bodyroll, while that of the reaction effects of limb accelerations was to resist bodyroll. These results clearly indicate that the primary source for propelling bodyroll was the external torque. Implications towards the mechanical interactions among bodyroll, stroke frequency, and forward propulsion in front crawl swimming were discussed.

Clinical theory suggests that altered alignment of the shoulder girdle has the potential to create or sustain symptomatic mechanical dysfunction in the cervical and thoracic spine. The alignment of the shoulder girdle is described by two clavicle rotations, i.e, elevation and retraction, and by three scapular rotations, i.e., upward rotation, internal rotation, and anterior tilt. Elevation and retraction have until now been assessed only in patients with neck pain. The aim of the study was to determine whether there is a pattern of altered alignment of the shoulder girdle and the cervical and thoracic spine in patients with neck pain. A three-dimensional device measured clavicle and scapular orientation, and cervical and thoracic alignment in patients with insidious onset neck pain (IONP) and whiplash-associated disorder (WAD). An asymptomatic control group was selected for baseline measurements. The symptomatic groups revealed a significantly reduced clavicle retraction and scapular upward rotation as well as decreased cranial angle. A difference was found between the symptomatic groups on the left side, whereas the WAD group revealed an increased scapular anterior tilt and the IONP group a decreased clavicle elevation. These changes may be an important mechanism for maintenance and recurrence or exacerbation of symptoms in patients with neck pain.
