The effect of consuming the hypercholesterolemia rationed food to the body weight of white rats wistar with administration of lactic acid bacteria

The aim of this study were to identify the in-vitro tolerance of pro-biotic bacteria to acid and bile salt condition; and to prove a hypothesis that the supplementation of oxygenated water has a positive effect on the body weight of rat and on viability of pro-biotic bacteria. The first study was carried out at PAU Laboratory of Bogor Agricultural University, while the second study was conducted at Department of Community Nutrition of Bogor Agricultural University and Microbiology Laboratory of Indonesia Institute of Technology. Forty five rats aged 6 weeks were divided into three groups, i.e., control group without probiotic (a0), Lactobacillus casei Shirota (a1), and Lactobacillus IS-7257 (a2). Each group (consisting of 5 rats each) has three different treatments, namely, control without oxygenated water (b0), 50 ppm oxygenated water (b2), and 80 ppm oxygenated water (b2). Oxygenated water was administered to the rats twice a day in the morning (3.25 ml) and afternoon (3.00 ml). Observation was carried out on the body weight of the rats, fecal lactic acid bacteria, coliform, and anaerob bacteria by plate counting, for 4 periods, i.e, prior to the treatment (C0), after three-day treatment (C1), after seven-day treatment (C2), and on the 10th day treatment or three days after washed out period. The results indicated that probiotic bacteria are resistant to acid and bile acid condition. Oxygen concentration in water has a significant positive influence on the body weight of rats towards viability of probiotic bacteria (p-level < 0.05). The supplementation of oxygenated water 50 ppm significantly increase the population of viable fecal lactic acid bacteria in L. casei Shirota and Lactobacillus IS-7257 groups after 3 and 7 days of treatment. Lactobacillus IS-7257 gave better response than L. casei Shirota. The supplementation of oxygenated water 80 ppm significantly reduces the fecal coliform in-vivo in both L. casei Shirota and Lactobacillus IS-7257 groups (p-level < 0.05).

Ruminal Ph

A ruminant’s digestion depends on microbial degradation of feed rather than endogenous enzyme degradation as in most monogastric animals. The study was conducted to assess the effects of Lactic Acid Bacteria (LAB) strains administered as direct-fed microbials on weight gain and ruminal pH of Damara and Meatmaster sheep breeds. Sixty-four Damara and Meatmaster sheep breeds [Damara males (36.6 ± 8.3 kg); Damara females (28.9 ± 6.9 kg); Meatmaster males (24.6 ± 3.4 kg); Meat master females (21.5 ± 3.1 kg)] were subjected to a 30-day trial and divided into five treatment groups as follows: pellets with no antibiotic and no probiotics administered (T1); pellets with no antibiotics, only Lactobacillus rhamnosus SCH administered (T2); pellets with no antibiotics, only Lactobacillus rhamnosus AF3G administered (T3); pellets with no antibiotics, with the combination of Lactobacillus rhamnosus SCH and Lactobacillus rhamnosus AF3G, administered (T4); pellets fortified with antibiotic and no probiotic administered (T5). The animals were fed on commercial pellets fortified with or without antibiotics. Animals were each weighed, and rumen fluids were collected using a stomach tube, and pH was read immediately, before and at the end of the trials. Data obtained were subjected to analysis of variance using SPSS version 4.0. The results showed that the effect of treatment, sex and some of their interactive effects were significant (p <0.001) on the body weight of sheep irrespective of breed. The effect of treatments revealed that the animals in the combination of probiotics gained more weight than those in other groups. Damara breed had a heavier body weight than Meatmaster while males were 6 kg heavier relative to females (p <0.001). Only breed was significant (p <0.05) on weight gained. Treatment (p <0.05), breed (p <0.001) and their interactive effect (p <0.05) were significant on ruminal pH. The highest pH value was 7.27 for the T5 group and 7.37 for the Damara breed. Results suggest that LAB may have beneficial effects on the growth performances of sheep and therefore may be suitable as future growth promoters in sheep production, as they don't have any harmful residues compared to antibiotics.

Data on the study of the effect of a consortium of lactic acid bacteria on the morphological parameters of blood and the state of the intestinal microflora of white rats using a composition of probiotic strains of L. lactis, Lb. plantarum and E. durans SB18 in a ratio of 50:40:10. Thus, when determining the morphological parameters of the blood of rats at 14 days of use found a positive effect of probiotic strains of lactic acid bacteria on the hematopoietic function of laboratory animals. In particular, a significant increase in hemoglobin concentration, erythrocyte count, leukocyte count and hematocrit value was found by 14.9, 14.0, 22.5 % (P < 0.05) and 5.7 %, respectively, compared with the control group. In addition, the use of the drug for 14 days caused an increase in the average concentration of hemoglobin in the erythrocyte (MCНS) by 9.8 % (P < 0.05) and a tendency to decrease the average hemoglobin in the erythrocyte (MCН) and the average erythrocyte volume (MCV) by 0.45 and 9.0 %, respectively, compared with the control group. Both central and peripheral organs of the immune system were also significantly affected. In particular, the relative weights of the thymus and spleen increased by 21.1 (P < 0.05 ) and 9.8 % (P < 0.05), respectively. When determining the leukogram of peripheral blood of rats, it was found that the use of the study drug in animals of the experimental group caused a tendency to increase the number of neutrophils, lymphocytes and monocytes by 6.0, 0.5 and 19.8 %, respectively, with a slight decrease in eosinophils. The use of a composition of a consortium of lactic acid bacteria stimulated an increase in lacto- and bifidobacteria content of the large intestine of white rats. In particular, a significant increase in the number of bifidobacteria and lactobacilli was found by 4.3 and 5.2 % (P < 0.001), respectively, relative to the animals of the control group. In addition, 14-day application of the studied composition of probiotic strains contributed to a probable reduction in the number of opportunistic and putrefactive microflora. The number of Escherichia coli, Staphylococcus aureus and fungi of the genus Candida significantly decreased relative to control by 4.7 (P < 0.01), 2.6 (P < 0.05) and 13.3 % (P < 0.001), respectively, all this indicated the recovery of the body of laboratory animals. The positive effect of lactic acid bacteria of the formed composition persists until the 21st day of the experiment.

Blood Glucose Levels

In recent years, many authors have investigated the possible antidiabetic effect of lactic acid bacteria. Lactobacillus species constitute a major part of the lactic acid bacteria group and have been found to exhibit beneficial effects on the development of diabetes and its complications. In the current study, we investigated the effects of newly characterised Bulgarian Lactobacillus strains, Lactobacillus brevis 15 and Lactobacillus plantarum 13, on blood glucose levels and body weight of rats fed a fructose-enriched diet. An experiment was conducted over a period of 8 weeks with 24 2-month-old Wistar rats randomly assigned to receive a standard diet (Con, control group), fructose-enriched diet (Fr group), standard diet with probiotics given twice a week (Pro group), and fructose-enriched diet with probiotics given twice a week (Pro+Fr group). At the end of the experimental period, a statistically significant increase in body weight was observed in all experimental groups (P<0.0001). The highest rise was seen in the fructose group (Fr, 169±19 g), followed by the Pro+Fr group (153±15 g), Pro group (149±13 g), and Con group (141±5 g). Moreover, the final blood glucose levels had risen significantly in the groups receiving fructose either without (Fr; P<0.0001) or with lactobacilli (Pro+Fr; P=0.002), while the rise was insignificant in the group of rats given probiotic supplementation only (Pro, P=0.071) and inexistent in the Con group (P=0.999). The highest elevation of blood glucose levels was observed in the Fr group (3.18 mmol/l), followed by the Pro+Fr group (2.00 mmol/l) whereas the Pro group showed the lowest levels (0.60 mmol/l). The results of our study suggest that the newly characterised Bulgarian Lactobacillus strains, L. brevis 15 and L. plantarum 13, could be considered as possible probiotics and might be able to prevent some metabolic disturbances.

Introduction. Historically, pesticides are evaluated more strictly from a medical point of view than other chemicals. Since their features, such as deliberate introduction into the environment, the possibility of contact with them by large masses of the population, and the high biological activity determine their potential danger to humans. Purpose of research - study of the biological effect of a technical product derived from triazoles when it is repeatedly ingested orally in mammals (rats), establishment of inactive and active doses, justification of the permissible daily dose (DSD) for humans. Material and methods. In acute experiments, white rats were used, including 6 animals in the group. Tested dose: 500-4000 mg/kg of body weight. A chronic (12 months) experiment was performed on 80 male rats with a bodyweight of 180-190 g at the beginning of the study. Tested doses: 5.0; 16.0 and 55.0 mg/kg of body weight (1 control and 3 experimental animals, 20 individuals each). In the dynamics of the experiment, we observed the condition and behavior of animals, water, and food consumption, recorded the timing of death, changes in body weight, physiological, biochemical, and hematological indices. Results. Indices of the acute oral toxicity on the studied product LD50 male rats were 2250 ± 483 mg/kg body weight. The dose of 5.0 mg / kg of body weight was not found to cause significant changes in all studied indices. The doses of 16.0 and 55.0 mg/kg of body weight had a polytropic effect on the body in experimental animals. Discussion. The studied product for the acute oral toxicity refers to low-hazard compounds, the doses of 16.0 and 55.0 mg/kg of body weight has a polytropic effect on the mammalian body, causing changes in carbohydrate, lipid, and lipoprotein metabolism in the body of rats - was accepted as acting. The dose of 5.0 mg / kg of body weight, when administered in rats, there are no changes in all the studied parameters throughout the experiment, is accepted as invalid. Based on the inactive dose-5.0 mg/kg of body weight and taking into account the reserve factor of 100, we have scientifically justified DSD for a person at the level of 0.05 mg/kg. Summary. The conducted sanitary and Toxicological studies indicate the need to assess the toxicity of new technical products to the mammalian body, to increase the reliability of the developed hygiene standards in environmental objects and food products.

Suspension for injection “Amoxidev 15” is prescribed to fur-bearing animals (mink, fox), dogs and cats for the treatment of respiratory diseases (tonsillitis, tracheitis, pneumonia, bronchitis, rhinitis, sinusitis, bronchopneumonia), digestive (gastritis, enteritis, enteritis). genitourinary systems (nephritis, urethritis, urocystitis, mastitis, metritis, agalactia), musculoskeletal system (arthritis, osteoarthritis, joint injuries, tendonitis, hoof lesions), skin and soft tissues (eczema, dermatitis) caused by sensitive drug by microorganisms, including colibacillosis, streptococcus, bronchopneumonia, etc. Toxicological evaluation of the veterinary drug “Amoxidev 15” under the conditions of acute and subacute toxicological experiments on a model of white rats. According to the results of an acute toxicological experiment with intragastric administration of the drug “Amoxidev 15” white rats DL50 could not be calculated because the death of laboratory animals was not detected within 14 days after administration. The maximum administered dose (in absolute weight of the drug) was 20000.0 mg/kg body weight, which allows to refer the drug to class VI toxicity of relatively harmless substances (DL50 > 15000 mg/kg body weight), and the degree of safety to class IV – low-hazard substances (DL50 > 5000 mg/kg). According to the results of an acute toxicological experiment with subcutaneous administration of the drug “Amoxidev 15” white rats DL50 could not be calculated because the death of laboratory animals was not detected within 14 days after administration, the maximum dose was 5000.0 mg/kg body weight, therefore, the drug “Amoxidev 15” when administered subcutaneously by toxicity can be classified as class VI substances relatively harmless (DL50 Subcut > 4500.0 mg/kg). When administered subcutaneously to white rats, the drug “Amoxidev 15” under conditions of subacute toxicological experiment in doses of 0.1–1.0 ml/kg does not cause hemo-, hepato- and nephrotoxic effects on the body of laboratory animals, although 3-day administration of the drug in a dose 1.0 ml/kg body weight caused an increase in the activity of hepatospecific enzymes ALT and AST by 12.5 and 11.1 % (P < 0.05), respectively, relative to the control, which was restored to the control level 7 days after cessation.

Cricket farming has shown its potential to address food and nutrition insecurity in parts of the world. However, one of the remaining challenges limiting mass production of edible insects is the affordability of feeds. One possible way to address this issue would be to explore the use of traditional plants such as Moringa oleifera leaf (MOL) and Azadirachta indica leaf (AIL) that are locally available, are protein-rich and possesses some antibacterial properties in insect feed formulation. In this regard, a study was conducted to evaluate the effect of supplementation of MOL (5 or 10%) and AIL (5 or 10%) powder in the commercially used starter chicken feed on growth and microbial load of house cricket (Acheta domesticus) and field cricket (Gryllus bimaculatus). After feeding for four weeks, the supplemented feeds with 10% MOL or 10% AIL in A. domesticus and G. bimaculatus significantly decreased (P<0.05) the body weights. Also, supplementation with MOL (5 or 10%) and AIL (5 or 10%) increased the mortality in both cricket species. Although high counts of total aerobic, Enterobacteriaceae, lactic acid bacteria, bacterial endospores, yeasts and moulds were observed, significantly lower counts (P<0.05) of lactic acid bacteria and bacterial endospores were observed in treatments containing MOL (5 or 10%) and 10% AIL in both cricket species. After processing (toasting and boiling), significant reductions (P<0.001) of all vegetative microbial cells were observed but bacterial endospores were not completely eliminated. Thus, during production and processing of insects and insect-derived products, bacterial endospores would require special attention. Salmonella and Escherichia coli were not detected in processed crickets’ samples. In conclusion, supplementation with 5% MOL or 5% AIL can produce crickets with similar body weight as control feed. Mortality increased significantly when feeds were supplemented with either MOL or AIL powder. Supplementation with MOL and AIL powders significantly reduced the cell numbers for some bacterial groups in both cricket species.

Positive Effect

Naniura is a traditional Batak food that is made without going through a heating process, but is made through a fermentation process using acid and salt. The use of acid and salt acts as a preservative because it can inhibit the growth of pathogenic microbes and spoilage microbes. In addition, naniura fermentation has the potential to be a growth medium for lactic acid bacteria, most of which strains can act as probiotics. However, the potential for probiotic naniura is still rarely studied and studied, so this review article is made to examine the potential for probiotic naniura and the health effects that can be obtained. The writing of this journal uses the literature study method, namely by collecting information from various scientific sources. Several studies have shown that naniura contains lactic acid bacteria that can act as broad-spectrum antimicrobials and can specifically inhibit the growth of Salmonella typhi, Bacillus cereus, Clostridium botulinum, E. coli and S. aureus. Consuming probiotic foods can have a positive effect on health, including improving the quality of the digestive tract, increasing the immune system in the body and degrading lactose so that it can be used for lactose intolerant sufferers.

AGAINST THE NUMBER OF SPERMATOZOA, WEIGHT AND THE WEIGHT OF THE TESTES MALE WISTAR RATS (Rattus norvegicus) ABSTRACTThis research’s objective is to know the influence of injecting ethanol extract from a hibiscus into a number of common male rats (Rattus norvegicus). This research uses the approach of complete randomized design (CRD) onto 24 common white rats (Rattus norvegicus) that is divided into groups, where group 1’s approach is control without treatment, groups 2, 3, and 4’s approach is with treatment, with consecutive doses being 3.6 mg/ml; 7.2 mg/ml; and 14.4 mg/ml. The treatment is induced orally as large as 1cc per day for a total of 50 days following the spermatogenesis cycle. The variables that are being observed are the amount of spermatozoon cells, body weight, and testicle weight. The results of this research indicates that ethanol extract from hibiscuses, from a quantity perspective, can decrease spermatozoon cells, and it may also influence the body weight and testicle weight of the subject, in this case are common rats (Rattus norvegicus) but, from the mathematical results from Analysis Of Variance, ethanol extract from the leaves of a hibiscus cannot decrease the amount of spermatozoon, body weight, and testicle weight of a common white rat (Rattus norvegicus).Keywords: Spermatozoon Cells, Hibiscus (Hibiscus rosa-sinensis L.), Common (white) rat (Rattus novergicus)
