Diagnostic Outcomes

A complete ultrasound examination (cUS) of the liver was performed on 172 female sheep and compared to the performance of a fast-focused ultrasound technique to diagnose echinococcal cysts. The scanned area was divided in: HYP (right hypocondrium), zone (Z)1 from HYP to the 11th intercostal space (IS), Z2 (10th–8th IS) and Z3 (7th–5th IS). Contiguous scans were also examined (HYP + Z1, Z1 + Z2, Z2 + Z3). Furthermore, during the procedures, the sheep were divided into three groups according to the body weight: Group (G) 1 (lighter), G2 (medium), and G3 (heavier). Finally, diagnostic outcomes were compared with necropsy findings. cUS obtained the highest values of sensitivity (Se) (91%), Specificity (Sp) (80%), and positive-zones (124/138, 90%), as compared to the other scans. cUS was also characterized by high values of Se and Sp and was able to identify a great number of positive-zones, when sheep were divided by body-weight groups. Similar performances were obtained in G1 by HYP (Se: 91%–Sp: 82%; 18/20, 90% of positive-zones) and HYP + Z1 scans (Se: 91%–Sp: 82; 90% of positive-zones, 18/20). Thus, in lighter breeds, the examination of HYP and HYP + Z1 scan windows could be considered reliable techniques for identifying the infected animals, while in heavier sheep the cUS still represents the best option.

Introduction The development of stenoses after correction of an esophageal atresia or acid and lye burn of the esophagus are well-known problems in pediatric surgery. Currently, stenoses are treated in the majority of cases by repeated balloon dilatations. The diameter of the balloons used is not standardized; standard curves do not exist. The aim of this study was to evaluate the diameter of the esophagus correlated to the body weight of the children as measured in upper gastrointestinal (GI) studies to answer the important question to what extent a stenosis should be dilated. Materials and Methods Within the time period from 2011 through 2016, 60 patients with upper GI studies were selected. Evaluations were blinded to two different examiners. The diameters were measured under maximum contrast filling between the second and third rib (cranial point of measurement) and between the seventh and eighth rib (caudal point of measurement). For both, the anteroposterior and lateral aspect was examined. The diameter was calculated as the arithmetic average of both measurements within one level. The diameters were correlated to the weight of the children. Results All children (n = 38) within the 3rd to 97th weight percentile were analyzed. Linear correlation and coefficients of 0.67 at the cranial point and 0.70 at the caudal point were found. Mean diameter at the cranial point of measurement was 6.75 mm at the lowest weight (2.6 kg) and 14 mm at 74 kg. Mean weight of these children (standard deviation [SD]) was 25.3 (18.8) kg and median age was 7 years. Within weight groups (0–10 kg; 10–20 kg; 20–35 kg; 35–50 kg; >50 kg), we calculated SD and two side tested critical 95% confidence interval for all measurements (n = 74). Conclusion Although the variation in measurements is considerable, this evaluation gives a reliable hint to which extent esophageal stenoses should be dilated in relation to the body weight. To the best of our knowledge, this is the first investigation to evaluate the diameter of the esophagus in children in relation to the body weight.

This study aimed to evaluate the production, reproductive performance, and productive efficiency of predominantly Charolais cows and their calves (Straightbred, ¾ C, ¼ N) according to body size at calving. Sixty-three cow-calf pairs were used and classified into three weight groups: Light (331.3±5.8 kg), Moderate (385.9±5.3 kg), and Heavy (424.4±6.2 kg). The classes were formed using half standard deviations above or below the average weight of the cows at calving. For each pair, the body weight was evaluated at calving, at weaning (63 days), at the beginning and at end of the reproductive period, and at 9 months for the calves. Pregnancy rates were similar (P > 0.05) between weight groups. The calves did not differ (P > 0.05) in terms of body weight and weight gain from calving until pregnancy diagnosis (210 days). The heavy cows had greater weight variations from 210 days to 270 days than the light cows. The calf production rate (kg calf/cow kept in herds) did not differ between weight groups. However, in relation to the weight of the cows at 210 days, light cows were 11.28% and 13.02% more productive (P < 0.05), than moderate and heavy cows, respectively. Light cows were more efficient than the other classes of cows at calving and at 210 days old. Our simulations showed that there were more kilograms for sale in herds of light cows (53.085 kg) than moderate and heavy cows (52.310 and 52.870 kg, respectively), while maintaining the structures of the herd constant. The size of the Charolais cow did not influence the weight of calves from calving until 7 months of age or their reproductive performance provided they were weaned early. The need for space for the maintenance of the cow-calf pair increased as the weight of the cows increased. In herds with smaller cows, higher numbers and a higher production of weight for sale are observed than in herds with moderate and heavy cows. Light cows were the most efficient at calving and during pregnancy diagnosis at 210 days.

Eggs obtained from a commercial broiler hatching-egg producer were assigned by weight to seven groups and set for hatching. After hatching, equal numbers of male and female chicks were placed in floor pens according to egg weight groups and weighed at day-old and weekly for 8 wk. Three additional groups of chicks consisted of: equal numbers of females from each egg weight group; equal numbers of males from each egg weight group; and equal numbers of males and females from each egg weight group. Analysis of the data indicated that the influence of egg weight on chick weight decreased with time. Significant differences in body weight among groups occurred for all ages for the females, whereas no significant differences occurred for the last two ages for the males. Chicks grown in the mixed egg weight groups did not differ from those grown separately. Even though statistical evidence indicated that egg weight did influence 8-wk body weight of females, factors such as cost of producing hatching eggs, price of day-old chicks, hatchability of eggs, length of growing period, and availability of hatching eggs, would have to be taken into consideration before deciding whether or not smaller eggs could be used profitably in the industry.

Abstract Salinomycin was evaluated for its toxicity and silymarin for prophylactic management in male rabbits. Male rabbits were randomly divided into 7 groups with 7 rabbits / each. Groups 1, 2, 3 were kept as control group, salinomycin (20 mg / kg ration) and salinomycin (40 mg / kg ration), respectively. Group 4 was fed on feed containing salinomycin (20 mg / kg ration) and silymarin (6.5 mg / kg body weight). Group 5 received feed containing salinomycin (40 mg / kg ration) and silymarin (13 mg / kg body weight). Groups 6 and 7 were nourished feed containing silymarin (6.5 and 13 mg / kg body weight), respectively. Duration of the experiment was 28 days. Weekly body weights showed a significant reduction in the 3rd group when compared with control group. The activity of Malondialdhyde and the values of aspartate aminotransferase, alanine aminotransferase, total protein, albumin, total cholesterol, triglycerides, low density lipoprotein, urea and creatinine were significantly elevated in 2nd and 3rd group while glutathione, catalase, superoxide dismutase and high density lipoprotein were significantly lowered when compared with control group. Thus, it is clarified that salinomycin toxicity is owed to oxidative damage and the usage of silymarin in feed tends to treat and prevent any accidental toxicity. Relative weight of the liver increased significantly in 3rd group. There were mild pathologic changes in liver of 2nd group while there were sever pathologic changes at 3rd group when compared with control group.

Female Sprague-Dawley rats, 10-12-week old and weigh ing about 240 g, were injected intravenously with 237Np nitrate. In the toxicological study 77 rats served as controls and 28 rats per group received single doses of 5.2 and 26 kBq, respectively, per kg body weight. In addition, 12 rats of each injection level, sacrificed at defined points in time, were used for dosimetric studies. During the whole life-span the body weight and 237Np whole body-content of each animal were recorded. After death a detailed pathological examination was made of each animal in the cronical study. One day after injection 48% of the injected activity was in the skeleton, 9.3% in the liver, 3% in the kidneys and 4.4% in the rest of the organs. Whereas in all organs the activity decreased very fast, the half-life in the skeleton was about 1400 days. The bodyweights were comparable in the three groups, but the life span decreased from 800 days (control group) to 644 days after injection (26 kBq kg -1 body weight group). The main lesions in the female rats were mammary tumors (73%) and pituitary gland tumors (52%). With increasing activity the incidence of pituary gland tumors decreased and that of osteosarco mas increased from 1.3% (control group) to 32% (26 kBq kg-1 body weight group), whereas the remaining lesions showed no influence on the activity.

Abstract. Title of the paper: Accuracy of dual energy X-ray absorptiometry (DXA) for the determination of the body composition of pigs in vivo New methods for the measurement of the body composition in vivo (or post mortem) like DXA need to be evaluated before routine use in livestock research or performance testing. Two body weight groups of pigs I) 30–50 kg (n=61) and II) 70–90 kg (n=62) were studied in this analysis. The whole bodies of the pigs were analyzed by a GE Lunar DPX-IQ scanner in vivo for the amount and percentage of fat, lean tissue, bone mineral, and the bone mineral density as well. Three days later, pigs were slaughtered and after a 24 h cooling period, the reference parts (shoulder, loin, side, and ham) of the left carcass half were dissected into lean meat, fat, bone, tendons, connective tissue and skin according to the EU reference method. Generally, DXA variables explained a high proportion of variation (R²>0.8; √MSE=70–784 g) in the tissue masses of the reference parts (fat, muscle, bone) in both weight groups. The fat percentage of the reference parts and the DXA whole body results (in vivo) showed a very high relationship with a maximum R²=0.82 (√MSE=1.47%) for group II. Slightly lower was the relationship between the lean meat content (%) of the reference parts and DXA results in vivo (R2=0.72; √MSE=1.75) for group II. The bone percentage was predicted with R²=0.3 (√MSE=0.64), caused by the very different analysis methods. Generally, DXA is a suitable method for growth studies in the above body weight range. In order to predict the percentage of muscle (lean meat) or fat tissue accurately by DXA, pigs should weigh >50 kg, since the soft tissue percentages of group I resulted in R²≤0.38 (√MSE≤2.55).

Abstract The goal of this study was to determine what effect obese body weight and a burn injury can have on the metabolism of glucose and lipids in rats. We used a 3*3 factorial model design to provide basic glucose and lipid metabolic data characterizing the interaction between different weight and burn injury groups. Two hundred Sprague Dawley (SD) rats were categorized into three weight groups (normal, overweight, obese) and then further divided into control, second degree, and third degree burn groups. Our model compared interactions between weight and burn injury factors according to the above groups. Blood glucose and lipid metabolism indicators were monitored on the 1st, 3rd, 7th and 14th days after burn injury occurred, and burned skin and blood samples were collected for testing. Compared with the normal weight group, the overweight group’s fast blood glucose (FBG), fast insulin (FINS) and homeostasis model assessment of insulin resistance (HOMA-IR) were higher (P&lt;0.05), and FBG in the obese group was higher than the normal weight group (P&lt;0.05).Burn injuries combined with obese body weight had an interactive effect on FBG, FINS and HOMA-IR after burn injury (P&lt;0.05). Burn injury combined with obese body weight had an interaction on low density lipoprotein cholesterol (LDL-C) on the 3rd day after burn injury (P&lt;0.05). Burn injury combined with obese weight had no interaction on triglyceride (TRG), total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) (P&gt;0.05).Rats in the overweight and obese weight groups were observed to develop an adaptation and tolerance to a higher metabolic rate after burn injuries occurred.

Abstract. The purpose of this work was to determine the effect of the body weights of day-old Muscovy ducklings on some slaughter value traits of females aged ten weeks and males aged twelve weeks. The relationships between the body weights of day-old ducklings, daily gains and slaughter value of grown-up ducks were also analyzed. The experimental materials comprised 96 White Muscovy ducklings (46 ♂ and 50 ♀). Males and females were reared separately, to twelve and ten weeks of age respectively. At the completion of the rearing period the birds were fasted for 12 hours and sacrificed. The carcasses were chilled, weighed and subjected to a detailed dissection. Before statistical calculations were carried out, males and females were divided into five weight groups, depending on their body weights on the first day following hatching. At the end of the experiment it was found that the grown-up ducks once classified as light, medium-heavy and heavy ducklings did not differ significantly in terms of body weight, mean daily gains, carcass weight, as well as the weight and percentage of particular tissue components in a carcass. Low and statistically non-significant values of the coefficients of simple correlation and regression suggest a lack of interdependences between the body weights of day-old ducklings and the slaughter value parameters of adult Muscovy ducks. The only exception was the carcass dressing percentage of males, which was found to be significantly negatively correlated with their body weights on the first day of life.

Previously, we have found that the addition of L-ascorbic acid to chitosan enhanced the reduction in body weight gain in guinea pigs fed a high-fat diet. We hypothesized that the addition of L-ascorbic acid to chitosan would accelerate the reduction of body weight in humans, similar to the animal model. Overweight subjects administered chitosan with or without L-ascorbic acid for 8 weeks, were assigned to three groups: Control group (N = 26, placebo, vehicle only), Chito group (N = 27, 3 g/day chitosan), and Chito-vita group (N = 27, 3 g/day chitosan plus 2 g/day L-ascorbic acid). The body weights and body mass index (BMI) of the Chito and Chito-vita groups decreased significantly (p < 0.05) compared to the Control group. The BMI of the Chito-vita group decreased significantly compared to the Chito group (Chito: -1.0 kg/m2 vs. Chito-vita: -1.6 kg/m2, p < 0.05). The results showed that the chitosan enhanced reduction of body weight and BMI was accentuated by the addition of L-ascorbic acid. The fat mass, percentage body fat, body circumference, and skinfold thickness in the Chito and Chito-vita groups decreased more than the Control group; however, these parameters were not significantly different between the three groups. Chitosan combined with L-ascorbic acid may be useful for controlling body weight.
