Abstract The search for new substances, alternatives to feed antibiotics in animal husbandry, is relevant in connection with the development of antibiotic resistance of pathogenic microorganisms. Substances of plant and mineral origin including nanoforms are of particular interest. The experiment studied the synergistic effect of iron (Fe; d = 80 nm) and an aqueous extract of oak bark (Ex; 1:10) on the microbiome of ruminal fluid of bulls (age 14 months, n = 5). Group I - control; Group II - Ex (0.6 ml / kg / lm); Group III - Fe (0.1 mg/kg/FM) with Ex in the same dosage. The collection of ruminal fluid was performed through a chronic ruminal fistula. Metagenomic analysis of cicatricial fluid was performed on a MiSeq device (Illumina, USA). Analysis of the data showed that the Bacteria domain is more influenced by Ex, there is a decrease by 27.0% (P ≤ 0.05), while in group III by 3.0% relative to the control. At the phylum level, Bacteroidetes and Firmicutes had the greatest importance, in group I their ratio was 39.3 and 54.7%, in group II - 37.7 and 56.4%, in group III - 46.1 and 47.0% of the total the number of bacteria. The use of Ex increases the amount of Bacilli by 14.7 and 13.4 (P ≤ 0.05) % relative to groups I and III. The introduction of the composition Ex and Fe increases Lachnospiraceae - 15.0% and Ruminococcaceae - 8.1% of the total number of microorganisms and reduces Streptococcus relative to other groups by 1.3 and 14.9% (P ≤ 0.05). Thus, the combined use of Ex and Fe affects the numerical value of microorganisms, as well as their ratio in the rumen through inhibition. At the same time, the data obtained require further research, including in vivo experiments. This research was performed with financial support from the RSF (20-16-00088).

This investigation was carried out to determine the effects of thuza and antim crud (Homeopathic preparations) on bovine cutaneous papillomatosis/wart. Nine calves of one to two and a half years age and of both sexes affected with cutaneous papillomatosis were randomly divided into three equal groups (group I, group II and group III) for this experiment from March 2002 to February 2003. Each calf of group I was first administered with 15 globules sulphur with a potency of 200-power once orally. This was followed after 7 days with 50M (M = 1000-power) thuza at the dose rate of 10 globules twice daily orally for a period of three weeks. The calves of group II were administered with sulphur and antim crud at the same dose, potency, route and duration, respectively and the calves of group III were kept as untreated control. Papilloma tissues were collected prior to treatment and at the sixth week of treatment and they were subjected to histopathological examination. Thuza and antim crud with concurrent use of sulphur were found effective in curing bovine cutaneous papillomatosis with a rate of 66.66% (4/6). Little or no reduction in size of the papillomas was observed within the first two weeks of treatment in both the treated groups (group I and group II). Thereafter, miniature size sessile and pedunculated papillomas started drying with the gradual reduction in size that fell leaving hairless areas at the end of fourth week. By the eighth week there was complete cure of papillomas. One calf of each treated groups (group I and group II) affected with large papillomas (5 X 7 cm) were not completely cured. Microscopic examination of regressive papillomas at sixth week of treatment showed cellular necrosis. Growth recurrence was not observed within one month of recovery. In the untreated control group (group III), the number and size of papillomas increased. Therefore, this line of treatment may be practiced for the treatment of bovine papillomatosis.

Purpose: to evaluate the effects of acute hypoxic hypoxia on eye tissue cells in adult rats and determining the effectiveness of 0.007 % solution of para-aminobenzoic acid (PABA) for apoptotic damage to the tissues of the ocular surface in rats.Materials and methods. In the experiment, 27 male Wistar rats (54 eyes) were used, divided into 5 groups. Group I — intact control, Group II — hypoxic control after 1 hour, Group III — hypoxic control after 3 hours, Group IV — with the injection of the drug 1 hour after hypoxia, Group V — injection of the drug 24 hours before hypoxia. The identification of apoptotic cells in the tissues of the eye was performed by the TUNEL method on frozen sections of the eye stained with Hoechst 33342 nuclear fluorescent dye. The localization and fluorescence intensity of the damaged cells was analyzed under a fluorescence microscope using the Image J. computer program.Results. Under the conditions of simulated acute hypoxic hypoxia, apoptotic lesions of the conjunctiva, corneal epithelium, choroid, and photoreceptor layer of the retina were observed. In group II, the number of damaged cells in the conjunctiva was 67 %, and in group III it was 120 % more compared to group I — the norm (p < 0.05). With the injection of PABA before hypoxia, there were no significant differences compared with the norm (group I) in the state of the affected cells in the conjunctiva. In the group of animals (group III) with the injection of PABA after hypoxia after 1 h, the number of damaged cells does not statistically differ from group II (hypoxic control after 1 h), but significantly lower than in group III (hypoxic control after 3 hours). The same pattern is observed in the corneal epithelium.Conclusion. Para-aminobenzoic acid (0.007 %) has a prophylactic and therapeutic effect, preventing and stabilizing the development of apoptosis of conjunctival cells and anterior corneal epithelium induced in experimental acute hypoxic hypoxia.

Irisin is a new myokine that is suspected to influence metabolic syndrome (MetS). However, there is a great controversy with respect to its level in cases of MetS and its correlation with different metabolic parameters. The present study assesses irisin levels in MetS patients and studies its relationship to metabolic and liver functions to evaluate the possible role of the liver in regulation of this level. Sixty subjects were included in this experiment, who were divided into 3 groups: group I (normal control), group II (MetS patients with normal liver enzymes), and group III (MetS with elevated liver enzymes and fatty liver disease). Serum irisin levels showed significant increases in groups II and III compared with group I, and significant increases in group III compared with group II. Also, irisin levels were positively correlated with body mass index, serum triglycerides, homeostatic model assessment of insulin resistance index (HOMA-IR), and liver enzymes. We concluded that serum irisin levels increased in patients with MetS, especially those with elevated liver enzymes, and had a positive correlation with parameters of lipid metabolism and glucose homeostasis with the possibility of hepatic clearance to irisin.

Determining which forms of mineral feed additives can increase farm animal productivity is a key area of research. This study assessed the mineral composition of ruminal fluid and the effectiveness of calcium and phosphorus used by animals after the introduction of finely dispersed particles (FDP) of SiO2 (group I) and FeCo (group II) with a hydrodynamic radius of 109.6 ± 16.6 and 265 ± 25 nm, respectively. The deposition and use of calcium and phosphorus in the body of the experimental animals exceeded the control values. In group I, 30.8% more calcium was deposited (p ≥ 0.05), and in group II, the value was 30.3% (p ≥ 0.01). In the experimental groups, the calcium utilization rate was 27.3% higher in group I (p ≥ 0.05), and 28.2% higher in group II (p ≥ 0.01) compared to in the control. Phosphorus deposition was 34% higher (p ≤ 0.01) in experimental group I and 6% higher in experimental group II, compared with the control. Group I had a high utilization rate of phosphorus from the feed (with a 29% difference compared to the control). Comparison of the experimental groups revealed that the introduction of SiO2 FDP promoted an increase in the concentration of silicon, phosphorus, and calcium in the ruminal fluid. The introduction of FeCo FDP was accompanied by a decrease in the concentration of iron and cobalt in the ruminal fluid. Thus, the use of feed additive in finely dispersed form in the diet of animals was accompanied by an increase in the use of calcium and phosphorus by the animal’s body, which is advisable when intensifying milk and meat productivity. The obtained results require further research. Keywords: finely dispersed forms of microelements, ruminants, calcium and phosphorus exchange, feeding

It has been shown that guineapigs can be effectively protected against re-infection by the subcutaneous inoculation of embryonated Ascaris eggs (Soulsby, 1957). The purpose of this communication is to report a successful attempt to immunize guineapigs against a lethal oral challenge dose of eggs by the intravenous inoculation of third stage larvae of A. suum.Three groups, each containing nine guineapigs, were infected with Ascaris as follows: Group I was given 10,000 eggs by mouth. Group II Was inoculated intravenously with 2,000 third stage Ascaris larvae which had been obtained from the lungs of other guineapigs on the sixth day of infection. Both groups were challenged at the same time with 250,000 eggs by mouth, along with a control group (Group III) which had no previous infection. The guineapigs in Group I were re-infected after 18 days and those in Group II after 12 days.

Background: Nephrotoxicity is characterized by raised serum urea and creatinine levels and kidneys being one of the primary organs of drug concentration and excretion are vulnerable to many widely used marketed drugs, including anti-cancer drugs, antibiotics, immunosuppressants, and radio contrast agents, are nephrotoxic. Aim: To determine the nephroprotective effect of ethanolic extract of Carica papaya seeds in Aminoglycoside induced acute nephrotoxicity. Study design: Quasi Experimental study. Methodology: Thirty Sprague Dawley rats were sub divided into 3 groups i.e., I, II and III with 10 rats in each group. Group II and III were administered Aminoglycoside drug; Gentamycin in 80 mg/kg) via intraperitoneal route once daily for 5 consecutive days to induce acute nephrotoxicity. At day 6, nephrotoxicity was confirmed by measuring serum urea and creatinine. Ethanolic extract of Carica papaya seeds (1000 mg/kg) was started once daily through oral route in group III for 5 consecutive days to see the nephroprotective effects of seed extract after causing acute kidney injury. All animals were given standard diet pellets manufactured at NIH. Results: Mean serum urea and creatinine for Group I (Control Group) at day 0 were 24.90 mg/dL ± 1.633 and .750 mg/dL ± .0619 respectively. Mean serum urea and creatinine for Group II (Disease Control Group) was 81.00 mg/dL ± 1.247 and 1.980mg/dL ± .0467 at day 6th. This suggested induction of nephrotoxicity by Gentamycin. Mean serum urea and creatinine for Group III (Ethanolic Extract Treated Group) at 11 day was 72.40mg/dL± .991 and 1.680 mg/dL± .0467 after 5 days treatment with ethanolic extract of Carica papaya seeds. Conclusion: We concluded that ethanolic extract of Carica papaya seeds has significant nephroprotective effects on Aminoglycoside induced acute nephrotoxicity in rats.

Abstract Background The duration of birth is an important factor influencing the survival of piglets and the health of sows. A prolonged parturition is usually treated with oxytocin, even though several undesirable side effects are described. Therefore, the aim of this study was to evaluate the safety and efficacy of Prostaglandin E2 (PGE2) of different concentrations as an intravaginal applied gel in sows. MethodsTwelve sows were randomly allocated to one of four treatment groups: Group I (control group) application of placebo gel; Group II application of 2.0 mg PGE2; Group III application of 1.0 mg PGE2; Group IV application of 0.5 mg PGE2. The gel was administered intravaginal after the birth of the fourth piglet. Total duration of birth (time between first piglet and last placenta), piglet interval and placenta expulsion duration (time between first and last placenta) were recorded, and each piglet was scored for meconium staining and vitality. Furthermore, stillborn piglets were categorized into ante-partum and intra-partum deaths. Results Although no significant differences between the groups were detected, a beneficial tendency in several parameters was observed in group III. The duration of birth was 284 min (average of 14.3 piglets per litter), whereas in all other groups it was more than 400 min (average of 18.0 piglets per litter). The piglet interval was 10.1 min in group II compared to 10.2 min in group III, 16 min in group IV and 21.4 min in group I. In group III the placenta expulsion duration was 119 min in contrast to the other groups with more than 266 min. Severe meconium staining in more than 10% of piglets was observed in group II and IV. Moreover, piglets of group II showed oedematous and haemorrhagic umbilical cords, lethargy and anoxia, and intra-partum deaths were recorded. Conclusion Although the sample size is limited in this study, it is assumed that an application of 1mg PGE2 intra-partum instead of lower or higher dosages has the most beneficial effects on the birth process in sows and on the vitality of piglets. Further investigation is necessary to confirm the positive effect of PGE2 in daily practise.

Abstract Background Tumours in mammary glands represent the most common neoplasia in bitches, as in humans. This high incidence results in part from the stimulation of sex hormones on these glands. Among mammary tumours, inflammatory carcinoma is the most aggressive, presenting a poor prognosis to surgical treatment and chemotherapy. One of the most widely used chemotherapy drugs for breast cancer treatment is doxorubicin (DOXO). Alternative therapies have been introduced in order to assist in these treatments; studies on treatments using stem cells have emerged, since they have anti-inflammatory and immunomodulatory properties. The aim of this study was to evaluate the effects of DOXO and canine amniotic membrane stem cells (AMCs) on the triple-negative canine inflammatory mammary carcinoma cell line IPC-366. Methods Four experimental groups were analysed: a control group without treatment; Group I with DOXO, Group II with AMC and Group III with an association of DOXO and AMCs. We performed the MTT assay with DOXO in order to select the best concentration for the experiments. The growth curve was performed with all groups (I-III) in order to verify the potential of treatments to reduce the growth of IPC-366. For the cell cycle, all groups (I-III) were tested using propidium iodide. While in the flow cytometry, antibodies to progesterone receptor (PR), estrogen receptor (ER), PCNA, VEGF, IL-10 and TGF-β1 were used. For steroidogenic pathway hormones, an ELISA assay was performed. Results The results showed that cells treated with 10 µg/mL DOXO showed a 71.64% reduction in cellular growth after 72 h of treatment. Reductions in the expression of VEGF and PCNA-3 were observed by flow cytometry in all treatments when compared to the control. The intracellular levels of ERs were also significantly increased in Group III (4.67% vs. 27.1%). Regarding to the levels of steroid hormones, significant increases in the levels of estradiol (E2) and estrone sulphate (S04E1) were observed in Groups I and III. On the other hand, Group II did not show differences in steroid hormone levels in relation to the control. We conclude that the association of DOXO with AMCs (Group III) promoted a reduction in cell growth and in the expression of proteins related to proliferation and angiogenesis in IPC-366 triple-negative cells. Conclusions This treatment promoted ER positive expression, suggesting that the accumulated oestrogen conducted these cells to a synergistic state, rendering these tumour cells responsive to ERs and susceptible to new hormonal cancer therapies.
