Antioxidant Enzymes Activities

The fungicide carbendazim (CBZ) and insecticide chlorpyrifos (CPF) are currently applied together by farmers for the control of pests. Here, we investigated the impacts of 7 days oral co-exposure to 10 mg/kg body weight of CPF and 50 mg/kg body weight of CBZ on selected oxidative stress and antioxidant biomarkers in the liver, kidney, and spleen of female rats. The results showed that while the body weight gain and relative organ weights were not significantly affected after separate exposure to CPF and CBZ, there was a significant decrease in the body weight gain with concomitant increases in the relative kidney and spleen weights of rats treated with the mixture. Also, CPF and CBZ co-exposure significantly increased the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), urea, and creatinine ( p < 0.05) when compared with the groups treated with CBZ or CPF alone and the control. The significant decreases in both antioxidant enzymes activities and nonenzymatic antioxidant level following individual administration of CPF and CBZ to rats were intensified in the co-exposure group ( p < 0.05). Additionally, the marked increases in the levels of oxidative stress indices in liver, kidney, and spleen of rats treated with CPF or CBZ alone were intensified in the co-exposure group ( p < 0.05). Histopathologically, co-exposure to CPF and CBZ exacerbates their individual effects on the liver, kidney, and spleen. These findings showed that co-exposure to CPF and CBZ in rats elicited more severe oxidative damage on the liver, kidney, and spleen of the rats, indicative of an additive effect compared to CPF or CBZ alone and as such, may pose a greater environmental risk to humans.

The Impact

Epidemiological and animal studies suggest that the alteration of hormonal and metabolic environment during fetal and neonatal development can contribute to development of metabolic syndrome in adulthood. In this paper, we investigated the impact of maternal high-fat (HF) diet on hypothalamic leptin sensitivity and body weight gain of offspring. Adult Wistar female rats received a HF or a control normal-fat (C) diet for 6 wk before gestation until the end of the suckling period. After weaning, pups received either C or HF diet during 6 wk. Body weight gain and metabolic and endocrine parameters were measured in the eight groups of rats formed according to a postweaning diet, maternal diet, and gender. To evaluate hypothalamic leptin sensitivity in each group, STAT-3 phosphorylation was measured in response to leptin or saline intraperitoneal bolus. Pups exhibited similar body weights at birth, but at weaning, those born to HF dams weighed significantly less (−12%) than those born to C dams. When given the HF diet, males and females born to HF dams exhibited smaller body weight and feed efficiency than those born to C dams, suggesting increased energy expenditure programmed by the maternal HF diet. Thus, maternal HF feeding could be protective against adverse effects of the HF diet as observed in male offspring of control dams: overweight (+17%) with hyperleptinemia and hyperinsulinemia. Furthermore, offspring of HF dams fed either C or HF diet exhibited an alteration in hypothalamic leptin-dependent STAT-3 phosphorylation. We conclude that maternal high-fat diet programs a hypothalamic leptin resistance in offspring, which, however, fails to increase the body weight gain until adulthood.

El consumo de stevia ha sido promovido por su bajo aporte calórico, su efecto antidiabético y antihipercolesterolémico. Sin embargo, los efectos de la ingesta de stevia parecen no ser los mismos para las ratas hembras respecto de los machos. El propósito de este estudio fue evaluar el efecto de la ingesta de stevia sobre el consumo de alimento, peso corporal y niveles de glucosa, insulina, colesterol y triglicéridos en ratas hembras Wistar durante 13 semanas y realizar un análisis predictivo del peso corporal y la ingesta de alimento a 20 semanas. Se utilizaron 20 ratas hembras adultas, que se dividieron en 2 grupos: control (CG) y stevia (SG), ambos grupos recibieron agua y comida a libre acceso, así como una solución de stevia al 0,2 % para el grupo SG. Se registró diariamente el consumo de alimento, agua y solución de stevia; la medición del peso corporal se realizó semanalmente. Al final de las 13 semanas de experimentación, los animales se sacrificaron para evaluar los parámetros metabolicos. El grupo SG mostró un mayor consumo de alimento, mayor proporción de ganancia de peso corporal, niveles de glucosa y colesterol que el grupo CG. No se encontraron diferencias significativas en los niveles de triglicéridos e insulina. Respecto al análisis predictivo (semanas 14-20), se mantiene un incremento significativo en el consumo de alimento y se observa una tendencia de aumento en la proporción de ganancia de peso corporal. Esto indica que el consumo de stevia en ratas hembras parece no tener los mismos efectos benéficos reportados en machos. Consumption of stevia has been promoted due to its low caloric intake, it’s effects as anti-diabetic and anti-hypercholesterolemic. However, the effects of stevia consumption is apparently not the same in females than males. The purpose of this study was to evaluate the effect of stevia intake on meal consumption, body weight and levels of glucose, insulin, cholesterol and triglycerides in female Wistar rats during 13 weeks and develop a predictive analysis of the body weight and meal intake over 20 weeks. 20 adult female rats were utilized, these were divided into two groups: control (CG) and stevia (SG), both groups received free access to water and food, the SG also received a stevia solution at 0.2%. Consumption of food, water and stevia solution was recorded daily, while weight was recorded weekly. At the end of the 13 weeks of experiment, the subjects were sacrificed to evaluate the metabolic parameters. The SG group showed a higher consumption of food, higher proportion of body weight gain, glucose levels and cholesterol than the CG. No significant differences were found in levels of triglyceride or insulin. Respect to the predictive analysis (weeks 14-20), a significant increase in food consumption is maintained and an increasing trend is observed in the proportion of body weight gain. This indicates that stevia consumption appears not to have the same benefit effects in female rats than male rats.

High Carbohydrate

Our earlier studies have shown that the artificial rearing of newborn rat pups [first generation high carbohydrate (1-HC)] on an HC milk formula resulted in chronic hyperinsulinemia and adult-onset obesity (HC phenotype). Offspring [second-generation HC (2-HC)] of 1-HC female rats spontaneously acquired the HC phenotype in the postweaning period. In this study, we have characterized the development of the abnormal intrauterine environment in the 1-HC female rats and the effects on fetal development under such pregnancy conditions for the offspring. 1-HC female rats demonstrated hyperphagia on laboratory chow and increased body weight gain beginning from the immediate postweaning period along with hyperinsulinemia and hyperleptinemia. During pregnancy, 1-HC female rats showed several metabolic alterations including increased body weight gain and increased plasma levels of insulin, leptin, proinflammatory markers, and lipid peroxidation products. Although there were no significant changes in the body weights or litter size of term 2-HC fetuses, the plasma levels of insulin and leptin were significantly higher compared with those of control term fetuses. Quantitation of mRNA levels by real-time RT-PCR indicated significant increases in the mRNA levels of orexigenic neuropeptides in the hypothalamus of 2-HC term fetuses. Collectively, these results indicate that the HC diet in infancy results in an adverse pregnancy condition in female rats with deleterious consequences for the offspring.

The aim of this study was to analyse the effects of different daily intakes of rapeseed bee pollen on the growth and biochemical blood serum indicators in male and female rats. A total of 40 clinically healthy male and female Wistar rats were randomly divided into four groups. In the control group (C) rats were fed a standard complete diet; in the experimental groups standard diets were supplemented with different doses of bee pollen. Treatment group T1 was given standard diet with the addition of bee pollen at a 0.3% concentration; in group T2 the addition was 0.5%; and in group T3 it was 0.75%. The experimental period lasted for 90 days. A significant effect (P < 0.05) of bee pollen on the body weight gain and feed conversion ratio of female rats was found. Significantly (P < 0.05) higher cholesterol concentration in blood serum of male rats was found in the groups with bee pollen addition (groups T2 and T3) compared to the control group. Lower triglyceride serum content in all female experimental groups (T1 and T3) was observed in comparison to the control. Higher serum cholesterol content in the experimental female rats was detected; significant differences were analysed in groups T1 and T3 compared to the control female group. Rapeseed bee pollen at concentrations of 0.5 and 0.75% positively affected the body weight gain of female rats, however, with higher feed consumption (P < 0.05). Rapeseed bee pollen reduced the triglycerides serum content in female rats and increased the cholesterol serum content in male and female rats (P < 0.05).

The Metabolic Syndrome

The estrogen deficiency after menopause leads to overweight or obesity, and physical exercise is one of the important modulators of this body weight gain. Female Wistar rats underwent ovariectomy surgery (OVX) or sham operation (SO). OVX and SO groups were randomized into new groups based on the voluntary physical activity (with or without running) and the type of diet for 12 weeks. Rats were fed standard chow (CTRL), high triglyceride diet (HT), or restricted diet (CR). The metabolic syndrome was assessed by measuring the body weight gain, the glucose sensitivity, and the levels of insulin, triglyceride, leptin, and aspartate aminotransferase transaminase (AST) and alanine aminotransferase (ALT). The exercise training combined with the CR resulted in improvements in the glucose tolerance and the insulin sensitivity. Plasma TG, AST, and ALT levels were significantly higher in OVX rats fed with HT but these high values were suppressed by exercise and CR. Compared to SO animals, estrogen deprivation with HT caused a significant increase in leptin level. Our data provide evidence that CR combined with voluntary physical exercise can be a very effective strategy to prevent the development of a metabolic syndrome induced by high calorie diet.

ABSTRACT Neonatal female rats were treated for 3 weeks (short term) or 8 weeks (long term) with antiserum to rat GH (anti-rGH) with or without replacement therapy with recombinant bovine GH (bGH). Body weight gain and tail length were significantly suppressed within the first 3 weeks and were even more markedly suppressed when treatment was continued for 8 weeks. When treatment was stopped in short-termtreated animals the rate of body weight gain recovered, although without evidence of catch-up growth. These effects were all normalized by concurrent treatment with bGH. Long-term anti-rGH treatment caused a profound reduction (80%) in the number of differentiated adipocytes in two internal fat depots, whilst the subcutaneous depot was only moderately affected (20%). In contrast, after recovery from short-term treatment with anti-rGH, the internal depots were only marginally decreased in both weight and adipocyte numbers, whereas the subcutaneous depot was actually doubled in size compared with controls, due entirely to an increase in the number of differentiated adipocytes. These data clearly demonstrate for the first time that GH is required for the differentiation of adipocytes in vivo. In addition, the results demonstrate distinct effects at different anatomical sites and suggest that GH may be one factor responsible for the differences described in numerous metabolic parameters and hormonal sensitivities of adipose tissue derived from different locations within the body.

The aim of the study was to determine the development of ramie plants (Boehmeria nivea L. Gaud) and the effect of using ramie leaves on feed on the body weight gain of Wonosobo Sheep (Dombos). Research on the development of ramie plants using survey methods in the area of ramie plant development in Wonosobo Regency. While the research on the use of ramie leaves for fattening was carried out in Butuh Village, Kalikajar District, Wonosobo Regency in 2018. 21 male Dombos were divided into 3 feed treatments with forage proportions of 70%, 50% and 30 ramie leaves respectively. %. The results showed that currently ramie plants were being developed in Wonosobo Regency by CV. Ramindo Berkah Persada Sejahtera in Gandok Village, Kalikajar District, Wonosobo Regency, Central Java. Until now the area of the crop has reached 13 ha. Of this area will produce ramie leaves 195,000 kg / year. If one sheep needs 4 kg of ramie / tail / day leaves, then the potential capacity of sheep is 135 heads / year, if the given one is 50% then the Jurnal Litbang Provinsi Jawa Tengah, Volume 16 202 Nomor 2 – Desember 2018potential capacity is 270 heads / year and if it is reduced again to 25% of ramie leaves then the potential capacity 440 heads / year. The use of ramie leaves as a feed for Wonosobo Sheep fattening can be given as much as 30% in fresh form.

The study was planned to evaluate the effect of exogenous fibrolytic enzymes (EFE) supplementation for 56 days @ 240 mg/kg total mixed ration (TMR) on digestibility of dry matter and nutrients in dairy cows. Six dry non-pregnant cows were assigned in each treatment with and without EFE. The digestibility trial of seven days was conducted after 49 days of feeding. Dry matter and nutrients intake of cows was not influenced by EFE. The supplementation of EFE had improved digestibility of dry matter, organic matter, crude fiber, neutral detergent fiber, cellulose (p less than 0.01), as well as digestibility of nitrogen-free extract and acid detergent fiber, was also higher (pless than 0.05). The body weight gain of cows was higher on the supplementation of EFE in TMR. The study concluded that feeding exogenous fibrolytic enzymes (240 mg/kg) supplemented TMR improved digestibility of dry matter and nutrients, which was reflected as higher body weight gain in dry non-pregnant Gir and crossbred dairy cows.
