Mastomys Coucha

SUMMARYIntraperitoneal implantation of adult gravid females of the bovine filarial parasite, Setaria digitata in Mastomys coucha was found to induce microfilaraemia lasting for about 125 days. The microfilariae (mf) could be detected as early as 4 days postimplantation (p.i.) and peak levels of about 30 mf in 20 µl of blood were observed by 21 days. A significant positive correlation was found between mf density and the body weight of recipients pre-implantation. The implanted adult worms were generally viable only for less than 1 week. Implantation resulted in a significant decrease in total leucocytes and erythrocytes, induction of eosinophilia, splenomegaly and anti-erythrocyte autoantibodies. The microfilariae in circulation developed into 3rd-stage infective larvae (L3) when fed onto Aedes aegypti (refm, Liverpool strain). The mf in circulation were found to be eliminated by oral administration of diethylcarbamazine citrate, indicating the usefulness of this model for screening potential anti-microfilarial drugs. During the microfilaraemic phase, priming with tetanus toxoid (TT) resulted in significantly decreased production of anti-toxin levels indicating a state of generalized immunosuppression. Induction of antibodies to various fractionated antigenic components of adult parasites could be demonstrated by enzyme immunoassay (EIA) in M. coucha implanted with live or cold-stunned adult worms. The S. digitata–M. coucha model thus is found amenable to perform chemotherapeutic and immunobiological investigations in experimental filariasis.

AbstractThe concentrations of growth hormone (GH), insulin (Ins), tri-iodothyronine (T3) and thyroxine (T4) in blood samples of growing yaks during different bimonthly seasons were determined by radioimmunoassay. The changes of body weight of growing yaks and composition of grass grazed were measured accordingly. The seasonal changes of hormones were significant (P < 0·01 or P < 0·05). Within season, the variances of hormones depended upon the different growing stages. The body-weight gains in the different groups varied in different seasons, increase being significant in May, July and September, decrease being significant from January to May. Correlation analysis indicated that T4 concentration had a significant positive correlation with the body weight of the growing yaks(r = 0·2509, P < 0·05) and other hormones did not have any significant correlation with body weight. The results showed that the annual cycle of weight loss and gain was attributed to the seasonal change of nutrition status. The seasonal change of the assayed hormones depended on the grass growth.

Blood Profiles

γ-Oryzanol (OZ), a bioactive phytochemical abundant in cereals such as rice, has been reported to be mainly hydrolyzed to ferulic acid (FA) in the body. Meanwhile, in our previous study, we revealed that a part of OZ is absorbed into the body and exists in its intact form. However, the comprehensive absorption profile of OZ and its metabolites (e.g., FA) after OZ intake has not been fully elucidated yet. Therefore, in this study, we measured the concentrations of OZ, FA, and FA conjugates (i.e., FA sulfate and glucuronide) in the blood of rats with the use of HPLC-MS/MS after a single oral administration of 300 µmol/kg body weight of rice bran OZ (RBOZ). As a result, intact OZ along with FA and FA conjugates existed in the blood, which implied that these constituents may all contribute to the physiological effects under OZ intake. Additionally, when an equimolar amount of FA (300 µmol/kg body weight) was administered, it was found that the absorption profile of FA was significantly different from that when RBOZ was administered.

Acute oral toxicity of methanol extract of Asiasari radix was evaluated in ICR mice of both sexes. In this study, mice were administrated orally with dosages of 1000, 3000, and 5000 mg/kg body weight of Asiasari radix extract. Mortality, signs of toxicity, body weight, food consumption, and gross findings were observed for 14 days post treatment of Asiasari radix extract. No mortality, signs of toxicity, and abnormalities in gross findings were observed. In addition, no significant differences were noticed in the body and organ weights between the control and treated groups of both sexes. These results show that the methanol extract of Asiasari radix is toxicologically safe by oral administration.

Background. To evaluate the biological response of the sows and their offspring with oral administration of Lactobacillus plantarum CAM6 in breeding sows, a total of 20 Pietrain breeding sows with three farrowings and their descendants were used, randomly divided into two groups of 10 sows each. Treatments included a basal diet (T0) and basal diet +10 mL biological agent containing 109 CFU/mL L. plantarum CAM6 (T1). No antibiotics were used throughout the entire experimental process of this study. Results. The L. Plantarum CAM6 supplementation in sows’ feeding did not affect ( P > 0.05 ) the reproductive performance of the sows; however, the number of deaths for their offspring before weaning ( P ≤ 0.05 ) decreased. In addition, the oral administration of Lactobacillus plantarum CAM6 in sows increased ( P ≤ 0.05 ) the content of lactose, nonfat solids, mineral salts, and the density of sows’ milk, with a decrease in milk fat. Moreover, the probiotic feed orally to the sows improved the body weight ( P ≤ 0.05 ) and reduced the diarrhea incidence of their offspring ( P ≤ 0.05 ). Also, the probiotic administration of sows changed ( P ≤ 0.05 ) the serum concentration of Na+, pCO2, and D-β-hydroxybutyrate and increased ( P ≤ 0.05 ) the leukocytes, lymphocytes, and platelets in their piglets. Conclusion. Oral administration of Lactobacillus plantarum CAM6 in breeding sows improved body weight, physiological status, and the health of their offspring. And preparing the neonatal piglets physiologically is of great importance to the pig farming industry which could decrease the operational cost and medication (especially antibiotics) consumption of the pig producers.

Indian White Leghorn strain-IWK has been improved for higher egg weight as well as number over last twelve generations at ICAR-Directorate of Poultry Research, Hyderabad. The data collected on various economic traits of egg production were analyzed using REML approach of animal model. Current study showed that the heritability estimate of body weight, age at sexual maturity (ASM), egg numbers and egg weight was moderate to high, low to moderate, low and high, respectively. The body weight was positively correlated with egg weight but negatively correlated with egg numbers. The body weight at 16 and 20 weeks were negatively correlated with ASM and were very important for achieving early ASM. ASM was negatively correlated with egg numbers. The egg weight regressed as the egg number increased. The part period egg production EP52 was highly correlated with EP64; therefore EP52 can be used for selecting parents for higher egg number instead of EP64.

Oxygen uptake (VO2) through the gills of a hill-stream fish Glyptothorax telchitta from the Saptakoshi river (Nepal) has been studied in relation to different body weights. The oxygen uptake was determined at 24.0±1°C using a cylindrical glass respirometer with continuous water flow system. The aquatic oxygen uptake through the gills increased from 1.048 to 8.115 mlO2 kg-1.h-1 within the body weight range of 3.215 to 31.355 g. A fish of 17.052 g average body weight consumes 4.461 mlO2-1.h-1. The relation between oxygen uptake (VO2) and body weight was determined by performing regression analysis using logarithmic transformation. It has been found that with a unit increase in body weight, the oxygen uptake per unit time (mlO2h-1) increases by a power of 0.930 showing significant positive correlation whereas, the weight specific oxygen uptake decreases by a power of 0.070 showing significant but negative correlation.

Abstract. This study estimates the additive and non-additive variances for egg production and body weight traits of two lines of quails from a long-term selection with the help of the REML method. For the body weight of 42-day-old females (BW42f) and males (BW42m), a total of 7,934 records for line 1 and 7,214 records for line 2 from 21 generations were used in our analyses. Additionally, 1,717 records of females from line 1 and 1,671 records of females from line 2 contained information on their egg production at an age of 42 to 200 days (EN200), on the average egg weight for the first 11 weeks of their laying season (EW1), on the average egg weight from weeks 12 to 23 (EW2), and on their body weight at an age of 200 days (BW200f). A multivariate additive animal model and one-trait dominance models, which include the inbreeding coefficients as covariates, were fitted to the data. The estimates of the heritability gained from our dominance models were smaller than those from the additive model. For line 1, the heritability values decreased for EN200 from 0.35 to 0.32, for EW1 from 0.66 to 0.56, for BW200f from 0.42 to 0.38, and for BW200m from 0.51 to 0.49, respectively. For the first line, the respective ratio (d2) of the dominance variance to the phenotypic variance for EN200, EW1, BW200f and BW200m was 0.08, 0.22, 0.09 and 0.21, and the values for the second line were 0.12, 0.06, 0.001 and 0.23.

The article investigates into changes of clinical parameters and leukograms of pigs with respiratory syndrome in comparison with the use of unprotected antibiotics penicillins (amoxicillin suspension 15%), third generation cephalosporins (ceftracone) and complex therapy (ceftracone in combination with oral administration of aflubin). In pigs, many pathogens (bacteria and viruses) parasitize, which can affect the upper respiratory tract. Failure to observe the rules for the use of antibiotics for the treatment of animals leads to the formation of resistant forms of microorganisms. Therefore, the introduction of treatment regimens that simultaneously have a polyvectoral action and stimulate the functioning of the body systems (as well as the work of homeopathy), allows you to achieve a positive therapeutic effect more quickly. In a private household where pigs are kept fattened, the disease of pigs with respiratory syndrome is registered, mostly in 14–28 days after purchase. In such animals, body temperature increased to 41.0–41.1 degrees Celsius, fever, weakness, lack of appetite, animals buried in the litter, and in the leukoformula, a slight increase (by 4.8% excess of the upper physiological limit) of lymphocytes and a slight decrease in segmental nuclei neutrophils (by a maximum 1.2% below the minimum physiological level). From pigs with respiratory syndrome, on the principle of analogues, formed three groups of 4 animals. For treatment, the first group used emulsion amoxicillin 15% from the rate of 1 cm3/10 kg of body weight of the animal, the second - ceftriaxone (20 mg/kg body weight 2 times a day for 3–5 days), the third – with ceftriaxone aflubin at the expense 10 drops (0.5 cm3/60 kg body weight for 3 days). Pigs eagerly consumed the drug when we took the drug into the syringe and orally, inserting the cannula for the lower lip. Based on randomized controlled trials, the simultaneous use of ceftriaxone intramuscularly and oral administration of Aflubine every 4 hours (during the first day), and subsequently with an interval of 12 hours for 3 days, contributes to complete clinical healing within the first day after commencing the use of drugs and shortens the treatment period pigs in 2 times, than the introduction of only ceftraxone. Oral use of aflubin in pigs administered intramuscularly amoxicillin provided cure for the next 12 hours, manifested by the restoration of appetite. Consequently, administration of aflubine with ceftriaxone and amoxicillin provides a reduction in the duration of pigs’ treatment with respiratory syndrome, which will reduce the use of antibiotics. Therefore, we consider it expedient to introduce into the schemes of this homeopathic remedy treatment in the therapy of pigs with symptoms of the infectious etiology respiratory system.

The aim of the study was to evaluate the toxic effect of Datura innoxia seeds and leaves on experimental rats by determining the elements content of seeds and leaves, the chemical compounds in aqueous and methanolic extracts of seeds and leaves and the chemical compounds in the stomach content of rats. Seeds and leaves were collected from El-Obied, North Kordofan State, Sudan, in October, 2016. The aqueous and methanol extracts were carried out by using maceration method and soxhelt apparatus respectively. Sixty five male albino wister rats, three months old and with an average body weight ranged 110-120 g, were randomly divided into thirteen groups, consisting of five rats in each group. Group 1 served as control and fed with normal rats food and water for thirty days. Groups 2, 6 and 10 administered aqueous seeds extract, groups 4, 8 and 12 received methanol seeds extract, groups 3, 7 and 11 received aqueous leaves extracts, groups 5, 9 and 13 received methanol leaves extract, all the groups received the same type of extract were administered 40, 60 and 80 mg/kg body weight respectively. The extracts administered to the rats intra gastrically using cathodal tube daily for thirty days. The elements in the leaves and seeds (K, Ca, S, Si, Cl, Fe, Al, P, Mg, Ti, Mn, Zn, Sr, Cu, V, Br and Zr) were determined by energy-dispersive X-ray fluorescence (EDXRF) spectroscopy. K content was the highest in seeds (5.469 ± 0.021%), Ca and S the highest in leaves (2.461 ± 0.019%, 1.254 ± 0.022 % respectively). The elements Ti, Mn, Sr, V, Br and Zr were detected in the leaves with range concentration 0.062-0.002%. The elements Si, Cl, Fe, Al, P, Mg and Zn concentration in seeds varied from 0.002 to 0.942% and in leaves varied from 0.014 to 0.346%. The concentration of these elements did not exceed the standard dangerous toxic levels. The effects of oral administration of leaves and seeds extracts to 60 healthy rats over 30 days were evaluated by monitoring the chemical changes of stomach contents. The analysis by gas chromatography-mass spectrometry (GC-MS) of aqueous and methanolic extracts revealed the presence of alkaloids (scopolamine, atropine and hyoscyamine), fatty acids, esters, amides, amino acids, ketones, coummarins, terpinoids, phenols, alcohols and hydrocarbons compounds. New compounds appeared in the stomach contents in the treated groups and this suggest that some compounds were metabolized and circulated in the body after the oral administration of leaves and seeds extract. The study concluded that the toxicity of seeds and leaves (methanolic and aqueous) extracts are nearly have the same toxic effects on rats due to their same active ingredients (alkaloids) and the oral administration of the extracts was found to be safe up to 40 mg/kg.

Obesity is a significant risk factor for chronic diseases. The effect of ethanol extract from germinated Keunnunjami, blackish-purple rice with a giant embryo, compare to ordinary brown rice, on the body weight and lipid and glucose metabolism in high-fat diet-fed mice was analyzed. Mice were fed with a high-fat diet-fed for 3 weeks and then orally administered with either distilled water (HF) or extract (0.25%, w / w ) from brown, germinated brown, Keunnunjami, and germinated Keunnunjami rice for 4 weeks. Control mice were fed with a normal diet and orally administered with distilled water. The HF group showed markedly higher body weight and triglyceride, cholesterol, fatty acid, glucose, and insulin levels than the control group. However, the oral administration of rice extracts ameliorated this high-fat diet-induced obesity, hyperlipidemia, and hypoglycemia through the modulation of adipokine production, lipogenic and glucose-regulating enzyme activities, and mRNA expression of genes associated with lipid and glucose metabolism. The germinated Keunnunjami extract exhibited greater hypolipidemic, hypoglycemic, and body weight-lowering effects than the other rice extracts. The results demonstrated that germination could further enhance the physiological properties of rice and that germinated Keunnunjami extract has a strong therapeutic potential against high-fat diet-induced obesity, hyperlipidemia, and hyperglycemia.
