There are results of the histological research of the immune system organs of rabbits after injection with a prophylactic drug «Pneumo-Pro», which includes two components: Streptococcus pneumoniae and 4% ethanol-water extract of propolis. Tentative reseaches on the development of preventive drug «Pneumo-Pro» showed enhancement of post-vaccination immunity in the application on the basis of propolis preparations. Histological reseaches of the diverticulum of the ileum and appendix found a significant amount of lymphoblasts, frequently visualized mitosis of lymphocytes in the center of submucosal lymphoid nodules is. Large, medium and small lymphocytes, macrophages are located in the dome of submucosal lymphoid nodules. The crown of the lymphoid nodules contains mainly lymphocytes of different maturity. Necrotic cells are rare. There is increase the amount of volume crowded lymphoid nodules in the lamina propria and submucosa in compare with the control group. Most of lymphoid nodules are located under the crypts, only a few of them are in contact with the intestinal lumen. Histological reseaches of the appendix of the experimental group of animals injected with «Pneumo-Pro» found B-lymphocytes, macrophages and interdigitive cells  are located in the periphery of the lymphoblasts. Quite often mitosis of lymphoid cells are visualized. Some lymphocytes are exposed with necrotic changes, resulting in small intervals are present between lymphoid elements. The peripheral part of the lymphoid nodules and interfollicular zone contain a significant number of T-lymphocytes. Crypts are placed above the top of many follicles. In the lamina propria and submucosa of the appendix there are numerous, voluminous accumulations of lymphoid tissue, which form the clusters of submucosal lymphoid nodules. The reseaches indicate an increase in the functional activity of nonspecific factors of resistance and immunobiological reactivity of organism of animals after injection with a prophylactic drug «Pneumo-Pro».

Complex classical morphological methods of studies were used in investigation. Pneumatic saccus is placed over the dorsal side of the pharynx and aside of it. Extended basis is attached to the ventral surface of the body and alar processes of sphenoid bone. Lateral wall of the pneumatic saccus is connected with the medial stylohyoid by loose connective tissue. In front, the dorsal wall is adjacent to the alar processes of sphenoid bone. Palatine processes of incisive bone are the basis of the hard palate in front part, maxillary palatine processes – in the middle part and horizontal plates of the palatine bones in the back part. Macroscopically tonsils are clusters of lymphoid tissue limited by connective tissue capsule under the epithelium of the tongue, soft palate and pharynx. Oral cavity mucosa in the tonsils area of cattle and small ruminants forms sinuses or numerous folds, which are separated by furrows of tongue and pharyngeal tonsils in other animal species. The cluster of separate lymphoid nodules and diffuse lymphoid tissue located at the root of the tongue between secretory units of serous mucous glands form the lingual tonsils. In the pharyngeal mucosa between secretory units of mucous glands lymphoid nodules of odd pharyngeal tonsil are located. Even palatine tonsils are located caudal to the palatoglossal arch and from sides of the tongue root. In horse diffuse tonsils crypts are located on the side of the tongue. Clusters of lymphoid nodules form tonsils of pharyngeal lymphoid ring. They have crypts, which look like hollow of the epithelium into lamina propria of mucosa, surrounded by lymphoid nodules and diffuse lymphoid tissue. The epithelium of the mucous membrane is flat non-keratinized stratified, infiltrated with lymphoid cells. Lamina propria of mucosa in the tonsil area forms a connective tissue membrane, from which layers of connective tissue with blood vessels depart to the middle. Glands’ secretory units are found in the connective tissue base, glands’ excretory ducts open into the lumen of the crypts. Lymphoid tissue is the basis of parenchyma, which is formed by reticular tissue and lymphoid cells.

AbstractOur aim was to detect type 2 innate lymphoid cells (ILC2s)-related cytokines of infants with bronchiolitis by using Elisa, Liquidchip technology and RT-PCR and investigated its correlation with bronchiolitis. We recruited 26 infants with bronchiolitis and 20 healthy infants as control from Xiangya Hospital. Compared to the control group, the serum levels of interleukin-5 (IL-5) [41.99 (21.11) vs 25.70 (19.64)], IL-9 [27.04 (37.51) vs 8.30 (0.54)], IL-13 [184.05 (132.81) vs 121.75 (176.13)], IL-33 [83.70 (46.69) vs 11.23 (55.31)] and thymic stromal lymphopoietin (TSLP) [31.42 (5.41) vs 28.76 (2.56)] were significantly increased in infants with bronchiolitis (P < 0.05), while the level of IgE had no significant difference between the two groups [19.05 (14.15) vs 14.85 (20.2), P > 0.05]. The mRNA expression of IL-17RB (9.83 ± 0.35 vs 9.19 ± 0.58), TSLP (16.98 ± 2.12 vs 15.07 ± 2.25), retinoid acid receptor related orphan receptor α (7.18 ± 0.71 vs 5.46 ± 1.09) and trans-acting T-cell-specific transcription factor 3 (4.86 ± 0.66 vs 4.19 ± 0.90) were significantly increased in infants with bronchiolitis versus the control group (P < 0.05), while there was no statistical significance for suppression of tumorigenicity 2 (5.59 ± 0.68 vs 5.41 ± 0.87, P > 0.05). Our findings suggested that ILC2s possibly play a specific role in immunopathology of bronchiolitis.

The increasing prevalence of allergic asthma has become the world’s major health issue. Current treatments for allergic asthma focus on treating symptoms, while permanent cures still remain undiscovered. In this study, we investigated the effect of Korean traditional herbal remedy, Pyunkang-tang (PGT)—composed of six plants—on asthma alleviation in a mouse model. The PGT mixture was orally gavaged to mice (PM group, 20 mg/mouse/day) from 7 days before sensitization with ovalbumin (OVA) (day −7). On day 0 and day 14, mice from OVA-control (n = 9) and PM group (n = 8) were sensitized with OVA and alum through intraperitoneal injection. On days 18~20, OVA was challenged to mice through nasal injection and sacrificed next day. Cell profile in lung tissue was analyzed by flow cytometry and RT-qPCR analysis, and the number of eosinophils and expression of siglec-F were significantly reduced in the PM group. Lung tissue was examined with hematoxylin and eosin (H&E) and Alcian blue/periodic acid–Schiff (AB-PAS) staining. Noticeably reduced eosinophil infiltration around bronchioles was displayed in the PM group compared to the OVA-control group. Furthermore, PGT-treated mice showed a significant reduction in IL-13 and a mild reduction in IL-5 in lungs. A decreasing tendency of IL-5/13 (+) CD4+ T cells and IL-13(+) innate lymphoid cells (ILCs) and a significant reduction in IL5(+) ILCs were also observed. When treating PGT on murine lung epithelial cells stimulated by papain, there was a significant reduction in IL-33 mRNA expression levels. Taken together, oral delivery of PGT successfully alleviated asthmatic responses provoked by OVA in a mouse model and could lead to novel therapies for allergic asthma.

Abstract The objective of this study was to evaluate the modified hydrated sodium calcium aluminosilicate (HSCAS) adsorbent ability to reduce the toxicity of T-2 toxin in broilers. 96 one-day-old male broilers were randomly allocated to 4 experimental groups with 4 replicates of 6 birds each. The four groups 1–4 were received the basal diet (BD), BD plus 6.0 mg/kg T-2 toxin, BD plus 6.0 mg/kg T-2 toxin with 0.05% modified HSCAS adsorbent, BD plus 0.05% modified HSCAS adsorbent, respectively, for 2 weeks. The growth performance, nutrients digestibility, and digestive tract histopathology were analyzed. Compared with the control group, dietary supplementation of T-2 toxin decreased (P &lt; 0.05) body weight gain, feed intake and feed conversion by 11.4–31.8% during d 1–7, d 8–14 and d 1–14. Dietary supplementation of T-2 toxin also decreased (P &lt; 0.05) the apparent metabolic rate of crude protein, calcium, and total phosphorus by 14.9–16.1% during d 8–14. These alterations induced by T-2 toxin were mitigated or prevented (P &lt; 0.05) by the supplementation of the modified HSCAS adsorbent. Meanwhile, dietary modified HSCAS adsorbent supplementation also prevented (P &lt; 0.05) T-2 toxin-induced morphological changes and damage, such as severe degeneration and desquamation of the villous epithelial cells, congestion in intestinal lamina propria, and edema and thicken in the serosa with infiltration of numerous lymphoid cells, in the gizzard, duodenum, jejunum, and ileum of broilers. Notably, dietary supplementation of the modified HSCAS adsorbent alone did not affect (P &gt; 0.05) any of those parameters. In conclusion, these findings indicate this novel HSCAS could be used as a promising adsorbent for protecting against T-2 toxin-induced toxicity in chicks (This work was supported in part by the National Key Research and Development Program of China, Projects 2018YFD0500601 and 2016YFD0501207).

Background: High fat diets are known to cause a positive fat balance and consequently to the accumulation of adipose mass, this diet does not seem to stimulate fat oxidation in the same way in obese and lean subjects. HFD was an inducing factor for ICAM-1 expression in the aorta of Wistar rats. HFD effect on ICAM-1 seems to be time dependent. ICAM-1 is one of the first events in the formation of atherosclerotic lesions. HFD up-regulated Cav-1, regulated expression other biomarker in HFD is eNOS. Recent studies showed that E. longifolia Jack protected HFD animal model from atherosclerosis based on the reduce atherosclerotic plaque size and formation HFD-rats treated with E. longifolia Jack.Objective: To prove that Eurycoma longifolia has anti inflammatory effect on endothelial cell blood vessels of Sprague Dawley rat with high fat diet.Method: Study design was experimental study, by used Randomized Post Test only Control Group Design with Kruskal-Wallis test was used to analyze the differences among groups and followed by a Mann Whitney test. Treatment is ethanolic or water extract of Eurycoma longifolia Jack, and out come are sICAM-1 and eNOS levels. Thirty Sprague Dawley (SD) Rat, were divided into 6 groups. C(-) was SD group, C(+) was group with HFD, X1 (SD treated with EL dosage 10 mg/kg), X2 (SD treated with EL dosage 15 mg/kg), X3 (HFD treated with EL dosage 10 mg/kg), X4 (HFD treated with EL dosage 15 mg/kg).

Infectious laryngotracheitis (ILT) is a respiratory tract disease affecting chickens around the world. The disease generates severe production losses due to increased mortality, decreased egg production, delayed body weight gain, and a predisposition to other respiratory pathogens causing enormous economic losses to the intensive poultry industry. Two licensed vaccines, comprising live or vectored ILT, are available to control the disease. The present trial was conducted to determine changes in chicken interferon gamma fold expression levels in chicken spleens and to evaluate tracheal lesion scores before and after vaccination with live and vectored infectious laryngotracheitis vaccines. Broilers were kept under commercial conditions until 35 days of age. Spleen and trachea samples were taken at 14, 28, and 35 days of age. Tracheas were stained with H&E, histopathology was performed, and the INF-γ fold expression level in spleen samples was analyzed. In the spleens of birds vaccinated with the live ILT vaccine, the increase in INF-γ expression levels was statistically significantly (p < 0.01) lower at 28 days of age, or 7 days post vaccination, (trial 1) and higher at 35 days of age, or 14 days post vaccination, (both trials). At 7 days post vaccination with the live ILT vaccine, the mean tracheal lesion score was significantly higher (p < 0.01) than it was in the control group (both trials). At 14 days post vaccination with the live ILT vaccine, the mean tracheal lesion score was significantly higher (p < 0.05) than it was in the control group 3 (trial 1). No significant differences were found between the control group 3 and group 2, which was vaccinated with the vectored HVT/LT vaccine (both trials). The results of the histology of trachea lesions indicate that vaccination with live ILT may have induced early local immunity. The INF-γ analysis results might indicate that the birds in group 2 (HVT/LT) did not develop local immunity until 35 days of age From the practical point of view, the vectored ILT vaccine is more beneficial because of its ease of administration in the hatchery, lower labor cost, and the absence of clinical signs post vaccination. Its potential drawback, however, is poor local immunity and the slow onset of optimal immunity in commercial broiler chickens

Abstract Background Streptococcosis and Motile Aeromonad Septicemia (MAS) are important diseases of tilapia, Oreochromis spp. and causes huge economic losses in aquaculture globally. The feed-based vaccination may be an alternative to minimize major infectious diseases in tilapia. Thus, this study aims to evaluate the haemato-immunological responses and effectiveness of a newly developed feed-based killed bivalent vaccine against Streptococcus iniae and Aeromonas hydrophila in hybrid red tilapia. A total of 495 hybrid red tilapia of 61.23±4.95 g were distributed into 5 groups (each with triplicate). The fish were immunized orally through bivalent (combined S. iniae and A. hydrophila ) spray vaccine (BS group), bivalent formulate vaccine (BF group), monovalent S. iniae vaccine (MS group), monovalent A. hydrophila vaccine (MA group) and unvaccinated as a control group. The vaccine was orally administered on days 0, 14 and 42 applied feed-based bacterin at 5% body weight. The blood and spleen samples were collected from all groups on 7, 21 and 49 days post-vaccination, and also 96 hours post-infection to assess their haemato-immune responses. Results Compared with the unvaccinated group, leukocyte, lymphocytes, monocytes, granulocytes counts in vaccinated groups were significantly ( P < 0.05) increased on 21, 49 days post-vaccination and also 96 hours post-infection, while erythrocytes, haemoglobin and haematocrit in vaccinated groups were significantly ( P < 0.05) enhanced only 96 hours post-infection. Additionally, the lysozyme and phagocytic activity and, serum antibody (IgM) were significantly higher ( P < 0.05) against S. iniae and A. hydrophila in vaccinated groups compared to the unvaccinated group in the pre- and post-infection. Results from the challenge through co-infection with S. iniae and A. hydrophila showed the relative percent survival (RPS) in BF group was 76.37±5.14%, which had the capacity to induce significant protection ( P < 0.05) compared to others groups. Conclusions This study demonstrates the bivalent formulate (BF) group could elicit significant non-specific and specific immunological responses with higher protection in hybrid red tilapia. In addition, this newly developed feed-based bivalent vaccination can be a promising technique for effective and large scale fish immunization in the aquaculture industry.

The effectiveness and high degree of biological effect of dead bees extract in medium doses on the nature and degree of morphofunctional rearrangements in the immunocompetent structures of the central and peripheral immune organs and immunocytological reactions in them have been established. A scientifically based scheme for the use of dead bees extract is proposed to improve the livability of livestock, increase live weight and improve the biochemical indicators of the quality of quail meat. Dead bees extract in low and especially in medium doses increase the production of the red bone marrow cells of the granular germ of white blood cells by 22,2 and 25,6 %, lymphoid cells by 4,7 and 6,9 %, erythroid germ by 2,3 and 11,0 %. Under the action of dead bees extract in the Fabricius bag quail strengthens the processes of maturation and differentiation of B-lymphocytes, which is manifested by extension immunocompetent cortical area in the 2nd and 3rd experimental groups (30 and 60 days of experiment by 10,4 and 22,1 % and 12,3 and 24,3 %, respectively), a reduction in brain area. The increase in the weight of the Fabricius bag (despite its general involution) in the 2nd and 3rd experimental groups on 30 and 60 days was 1,24 and 1,47, 2,59 and 3,0 times, respectively. In the thymus of quails under the influence of low and medium doses of dead bees extract the intensifi cation of maturation and differentiation of T-lymphocytes, resulting in the expansion of the cortical substance on 30, 60 and 90 days of 1,55 and 1,62, 1,42 and 1,73, 1,61 and 1,95 times, respectively, against the background of the depletion of brain matter, in excess of the thymus weight (with its expressed total involution) by 1,32 and 1,42, by 1,38 and 1,5, by 1,24 and 1,34 times, respectively. Dead bees extract activates the processes of antibody formation, increasing the immunological activity of the spleen in the form of expansion of the area of lymph nodes without light centers in the 2nd, 3rd and 4th experimental groups by 1,39, 1,83 and 1,5 times, respectively, and with light centers by 1,57, 1,79 and 1,19 times (B-zone). It increases the area of the perivascular lymphoid coupling (T-zone) by 1,5, 1,8 and 1,28 times, respectively, activates immunocytological reactions, increases the weight of the spleen of quails. The live weight of the males of the 2nd, 3rd and 4th experimental groups exceeded the control by 27,6, 31,8 and 18,9 g, and the females by 17,6, 27,7 and 9,9 g, respectively. The livability of livestock in the control group was 78,0 %, in the 2nd, 3rd and 4th experimental groups 89,0, 95,0 and 85,0 %, respectively.

Abstract Background and Aims The IgA nephropathy (IgAN) is the most frequent primitive glomerulonephritis. In the last years, the role of mucosal immunity in IgAN, together with that of the gut microbiota in the activation of innate and adaptive immune cells, has gained importance. Particularly interesting is the role of the microbiota and intestinal immunity in IgAN. BAFF and APRIL can be produced by the intestinal epithelium, in response to signals triggered by TLRs once activated by the commensal bacteria present in the intestinal lumen, representing the link between microbiota and intestinal immunity. To date, even if hypothesized, this relationship in IgAN patients has not been investigated. Here, we studied the intestinal-renal axis connections analyzing levels of BAFF, April and intestinal-activated B cells in IgAN patients. Method Serum and fecal samples were collected from 44 IgAN patients, 22 non-IgA glomerulonephritides (controls) and 22 healthy subjects (HS) with similar clinical features. BAFF and APRIL serum levels were measured by ELISA assay. Metabolomic analysis of fecal microbiome was performed using Biochrom 30 series amino acid analyzer and gas-chromatography mass spectrometry/solid-phase microextraction (GC-MS/SPME) analysis. B cell subsets were investigated by FACS. Results IgAN patients had increased serum levels of BAFF cytokine compared to the control group of patients with non-IgA glomerulonephritis and compared with HS (p&lt;0.0001and p=0.012, respectively). We found that serum BAFF levels positively correlated with the levels of 24h-proteinuria in IgAN patients (r2 = 0.2269, p &lt;0.001). We correlated serum BAFF levels with fecal concentration of 5 different metabolites of 30 IgAN patients, which were previously investigated for the fecal microbiota. These organic compounds had been found at significantly higher levels in the feces of IgAN patients compared to HS. Serum BAFF levels positively correlated with the levels of fecal metabolites: 4-(1,1,3,3-tetramethylbutyl) phenol (r2 = 0.2882, p = 0.0027), p-tert-butyl-phenol (r2 = 0.386, p = 0.0003), methyl neopentyl phthalic acid (r2 = 0.3491, p =0.0007), hexadecyl ester benzoic acid (r2 = 0.2832, p =0.003) and furanone A (r2 = 0.1743, p = 0.024). Serum levels of APRIL were significantly increased in IgAN patients respect to control groups (4.49 ± 0.54 vs 2.27 ± 1 ng/ml, p=0.0014). We found a correlation between APRIL and serum creatinine (r2 = 0.159, p =0.04) and eGFR (r2 = 0.2395, p =0.0082), while no correlation was found between APRIL and fecal metabolite levels in IgAN patients. In addition, we found that subjects with IgAN have a significantly higher proportion of circulating Bregs, Memory B cells and IgA secreting-plasmablasts activated at the intestinal level (CCR9+INTB7+) compared to HS. Conclusion The results of our study showed for the first time an important correlation of serum levels of BAFF with intestinal microbiota in patients with IgAN, confirming the hypothesis of the pathogenic role of intestinal mucosal hyperresponsiveness in the IgAN patients. The intestinal-renal axis plays a crucial role in Berger's glomerulonephritis, whose complex pathogenesis may contribute several factors as genetics, pathogens and food.

There is dearth of information on the haematological changes associated with Mannheimia haemolytica vaccination in goats, hence this report which describes some haematological changes observed following vaccination with intranasal Recombinant Mannheimia haemolytica vaccine in goats naturally infected with peste des petits ruminants (PPR) virus. Twenty one (male, n=11; and female, n=10) goats were assigned to three vaccinated groups (A, B and D) with five goats per group (male: 3, female: 2), while the control group had 6 goats. Group A was vaccinated once intranasally, group B was vaccinated intranasally twice at one week interval and group D was vaccinated intranasally twice at two weeks interval . The control group (C) was not vaccinated. The vaccinated and control groups were challenged by comingling with pneumonic goats to simulate the field experience. PPR virus infection was later diagnosed in all the groups post vaccination. An average of four animals per treatment group in post-vaccination days were bled once weekly for six weeks (every week) to evaluate some haematological changes. The PCV values were within the normal range, while there was a decline in lymphocyte count at week 5, and a steady increase in neutrophil count in group A. In Group B, there was similar decline in lymphocyte count from the sixth week, while in groups C (Control) and D, the lymphocyte count declined at the 7th week, as the neutrophil counts increased. There were no significant changes in monocyte and eosinophil counts. The degree of changes in lymphocyte and neutrophil counts was mild in group B and marked in group D. This study revealed that intranasal vaccination of recombinant Mannheimia  haemolytica vaccine in the presence of PPR virus outbreak results in mild hematological derangement when the goats were vaccinated with  Mannheimia haemolytica bacterin at a week interval.Keywords: Goats, Haematology, Intranasal Recombinant Mannheimia haemolytica, Peste des Petits Ruminants, Vaccination
