RESUMEN

BACKGROUND: The association between serum erythrocyte immune function indexes and blue light treatment effect and severity in child patients with pathological jaundice was testified. METHODS: One hundred and seven children with pathological jaundice and 69 children with physiological jaundice were enrolled to analyze the association between erythrocyte immune function indexes and blue light treatment or disease progression. RESULTS: The area under the ROC curve (AUC) of red blood cell immune complex rosettes (RBC-ICR) and red blood cell C3b receptor rosette (RBC-C3bR) in diagnosing pathological jaundice and assessing the efficacy of blue light therapy overweighed 0.8. Meanwhile, the RBC-ICR values of the child patients were positively correlated with the severity of the disease, and the RBC-C3bR and red blood cell immune affinity receptor (FEER) values were negatively correlated with them (p < 0.05). CONCLUSIONS: The erythrocyte immune function indexes of child patients with pathological jaundice were relevant to the disease severity, and was provided with diagnostic value for pathological jaundice or assessed value for the efficacy of blue light therapy.

RESUMEN

The poor correlation of developmental toxicity studies in animals with human outcome data has emphasized the need for complementary assays based on human cells and tissues. As neural tube defects represent an important proportion of congenital malformations, we evaluated here the accuracy of a human embryonic stem cell (hESC)-based assay to predict chemically induced disruption of neural tube formation. As teratogenic compounds, we used cyclopamine (CPA), valproic acid (VPA), ochratoxin A (OTA) and mycophenolic acid (MMF), all suspected or known inducers of human neural tube defects, as well as theophylline and saccharin as negative control compounds. We analyzed their effects on the ability of hES cells to give rise to neural precursors (expressing specific marker Nestin), to form neural tube-like structures (rosettes), and to express specific markers (Sox1, Otx2, Lix1, EvI1, Rspo3) during rosette formation. The results showed that various effects of the selected compounds on early neural development could be specifically revealed in vitro through related alterations of neurogenic differentiation of hESC. Furthermore, it was possible to discriminate toxicants acting at different time points during embryonic development and, therefore, responsible for distinct adverse effects on neural tube formation. By comparing four different hESC lines, we observed a significant (up to fivefold) variability of the line-dependent response to toxicants. We highlight at least two sources of variability: one related to the heterogeneity of hESC lines in culture (stemness/commitment profiles); the second to possible genetically determined differences in individual sensitivity to teratogens.

RESUMEN

The rosette-forming glioneuronal tumor (RGNT) is a novel type of brain tumor recently listed in the WHO 2007 classification of central nervous system (CNS) tumors. We report the case of a 75-year-old woman harboring a thalamic RGNT with third ventricle dissemination. Age and location make the present case exceptional and which has never previously been reported. A review of the clinical, pathological and radiological features is presented along with the relevant literature.

RESUMEN

It was demonstrated that an extract from the pharmacopoeial raw material bilberry fruit (Fructus Myrtilli) co-administered with selected antibiotics: cefuroxime, cefoperazone and doxycycline, positively affects the survival of mouse thymocytes in cultures with hydrocortisone (cytotoxicity test), increases the count of splenocytes forming spontaneous rosettes (E-rosette test) and increases the agglutination titre of mouse serum (active hemagglutination test). In the cytotoxicity test, the best protective effect has been obtained with the combination of doxycycline with bilberry fruit aqueous extract. The increased count of splenocytes capable of binding sheep red blood cells has been observed for cultures with cephalosporins (cefuroxime and cefoperazone). The highest agglutination titre has been demonstrated for mouse serum treated with the extract in combination with doxycycline and cefuroxime.

RESUMEN

OBJECTIVE: To study the erythrocyte immuno-regulatory effect of Patrinia scabra Bunge extracts extracted by macroporous adsorptive resins in tumor bearing mice. METHODS: Patrinia scabra Bunge was extracted by macroporous adsorptive resins, and the amount of polysaccharides and saponins in the extract were determined. Mice bearing S180 tumor were treated with the extract and their survival prolongation rate, erythrocyte rosette formation rates of C3b receptor (ERR-CR), immune complex (ERR-IC) and tumor cell (ERR-TC), as well as the CD35 and CD44s were observed. RESULTS: Polysaccharide content was 21.4%, saponin 41.8% in the extract. As compared with the model group, the survival rate was increased, the erythrocyte immune function was improved (showed increase of ERR-CR and ERR-TC, decrease of ERR-IC), and the amount of CD35 and CD44s in red blood cell membrane increased in mice after being treated with the extract (P < 0.05 or P < 0.01). CONCLUSION: Extract of Patrinia scabra Bunge extracted by macroporous adsorptive resins can regulate the erythrocyte immune function to a certain extent.

RESUMEN

In this study, the authors apply a computer-based strategy to screen thousands of small-molecule, nonpeptidic organic compounds in the Available Chemicals Directory database and to select a series of potential candidates as ligands of the proposed CD4 D1 surface pocket. Then, several cell-based models are used to determine the actual biological functions of these compounds. A small molecule designated A5 (N-((pyridine-4-yl)methylene)thiophene-2-carbohydrazide) was obtained by a virtual screening followed by 3 cell-based functional assays. The results show that A5 could specifically block the CD4-major histocompatibility complex II binding in a rosetting assay, inhibit the mixed lymphocyte reaction-induced T-cell proliferation in a concentration-dependent manner, and reduce the PMA plus ionomycin-stimulated interleukin-2 secretion from peripheral blood mononuclear cells.

RESUMEN

OBJECTIVE: To investigate the effect of Shenmai Injection (SMI) on immunologic function in patients with dilated cardiomyopathy (DCM). METHODS: Fifty-six patients were divided into two groups, the control group treated with conventional western medicine, and the SMI group treated with conventional western medicine plus SMI. The indices including red blood cell (RBC) C3b receptor rosette (RBC-C3bRR) and immune complex rosette (RBC-ICR), T-lymphocyte subsets (CD3, CD4, CD8, CD4/CD8) were determined before and after treatment. RESULTS: The level of RBC-C3bRR, CD4, CD8 and CD3 in patients with DCM were significantly decreased (P <0 .01, P < 0.05), RBC-ICR and CD4/CD8 were significantly increased than those in the normal control group (P < 0.01); While the level of RBC-C3bRR, CD4, CD8 and CD3 in the SMI group after treatment were significantly higher, and the level of RBC-ICR and CD4/CD8 were significantly lower (P < 0.01, P < 0.05) than those in the control group. CONCLUSION: The RBC immune adherence and cellular immune function are lower in patients with DCM, and SMI has the effect in regulating immune function in patients with DCM.

RESUMEN

Demodex canis is a natural inhabiting mite of canine skin. Immunological disorder or genetic disorder induces the Demodex population to proliferate vigorously resulting in generalized demodicosis with consequent chronic immunosuppression. Signs of generalized demodicosis include alopecia, crysting, erythema, secondary pyoderma etc. Amitraz, an acaricide, is used conventionally for the treatment of generalized demodicosis. In many instances, the disease relapses due to the residual immunosuppression. The need of an immunorestorative therapy has been urged in generalized demodicosis. Two immunorestorative drugs, namely, Immuplus, a herbal drug, and T11TS, a sheep erythrocyte surface glycoprotein, has been used in two separate groups of dogs having generalized demodicosis and receiving Amitraz treatment. It was observed that though Amitraz treated group responded to the therapy showing increased E-rosettes and nonspecific cytotoxic efficacy of T-lymphocytes and decrease in phagocytic potential of macrophages, the groups treated with the immunotherapeutics like Immuplus and T11TS, responded better. However, the group treated with T11TS showed best recovery. These results emphasize the need for an immunorestorative therapy in generalized demodicosis and provide data in favor of T11TS as a better immunomodulator in comparison to Immuplus.

RESUMEN

We investigated the effects of polysaccharide extracts from 2 mushrooms, Lentinus edodes (LenE) and Tremella fuciformis (TreE), and an herb, Astragalus membranaceus (AstE), on cellular and humoral immune responses of Eimeria tenella-infected chickens. A total of 150 broiler chicks were assigned to 5 treatment groups: 3 groups were infected with E. tenella and fed with extracts (LenE, TreE, and AstE), and 2 control groups were infected with or without E. tenella. The 3 extracts were given at the level of 1 g/kg of the diet from 8 to 14 d of age. Specific systemic and cecum mucosal antibody production, proliferation of splenocytes, and peripheral T and B lymphocytes were measured during the 3 wk following Eimeria infection. A significantly higher production of specific IgA, IgM (at d 14 and 21 postinfection), and IgG (at d 21 postinfection) were detected in the Eimeria-infected groups fed with the extracts than in the infected group not fed with the extracts. Of the 3 extracts, TreE stimulated a slightly higher production of specific IgM (P = 0.052), and a significantly higher IgG production at 21 d postinfection. The cecal antibody production showed a similar trend to that of serum antibodies. The overall mean levels of cecal-specific IgA and IgG of the groups fed with extracts were significantly higher at 14 and 21 d postinfection compared with the group not fed with extracts. Of the 3 extracts, the AstE-fed group showed the highest IgG production at d 7 postinfection. Both TreE- and LenE-fed groups had significantly higher IgM and IgG levels compared with the AstE group at d 21 postinfection. The extract-fed groups also showed a significantly higher antigen-specific proliferation of splenocytes at 14 and 21 d postinfection compared with the group not fed with the extracts. The overall mean of erythrocyte rosette-forming cells (ERFC %) (at d 14 and 21) and erythrocyte-antibody-complement cells (EAC %) (at d 14) of the groups fed with the extracts was significantly higher compared with the group not fed the extracts. It is concluded from this study that supplementation with mushroom and herb extracts resulted in enhancement of both cellular and humoral immune responses in E. tenella-infected chickens.

RESUMEN

UNLABELLED: The objective of the study was to investigate the mechanisms of action of Purple Coneflower (Echinacea purpurea (L.) Moench) preparations on the immune system and to define which part of the plant is the most effective as an immunostimulator. MATERIAL AND METHODS: The extracts from overground parts and roots of Purple Coneflower were injected into rabbits at the dose of 1 ml/kg. The stimulation of T lymphocytes in vitro was tested by incubation of rabbit blood with the different concentrations of the Purple Coneflower preparation (10, 50, 100 microg/ml) and assessed by the method of spontaneous rosettes. The number of lymphocytes, which bind to heterogenic erythrocytes, was counted. In order to determine the local effect, 30 ml of Purple Coneflower preparation (95 mg of dry material/1 ml) was used for the rinsing of mouth cavity in humans. The reaction of phagocytosis was assessed by using latex particles and calculating phagocytosis activity and phagocytosis index. RESULTS: Purple Coneflower extracts from roots were more effective phytoimmunostimulators than those from overground parts. They significantly increased in vivo the number of leucocytes and lymphocytes, especially T lymphocytes, in peripheral blood of rabbits as compared with the control group (p<0.001). The stimulation of T lymphocytes by Purple Coneflower preparation in vitro was the most pronounced at the concentration of 50 microg/ml (20.8+/-1.01% of spontaneous rosettes, p<0.001 with control). An increase in concentration till 100 microg/ml was followed by non-specific inhibition (9.16+/-1.6% of spontaneous rosettes, p>0.05 with control). Purple Coneflower preparations activated phagocytosis of neutrophils in vitro and in vivo. After rinsing mouth cavity with 30 ml of Purple Coneflower root preparation for 15 minutes, phagocytosis activity was significantly increased till 36% (p<0.05 as compared with the control (27%), where physiological solution was used for the rinsing). This local application of Purple Coneflower root preparation has significantly increased phagocytosis index up to 1.03 (p<0.02 as compared with the control index (0.65) after rinsing of the mouth cavity with physiological solution). CONCLUSIONS: Purple Coneflower preparations from roots activate the cellular immunity and stimulate phagocytosis of neutrophils in vitro, in vivo and after rinsing of mouth cavity.
