and other aspects o...BACKGROUND Painless gastroenteroscopy is a widely developed diagnostic and treatment technology in clinical practice.It is of great significance in the clinical diagnosis,treatment,follow-up review and other aspects of gastric cancer patients.The application of anesthesia techniques during manipulation can be effective in reducing patient fear and discomfort.In clinical work,the adverse drug reactions of anesthesia regimens and the risk of serious adverse drug reactions are increased with the increase in propofol application dose application dose;the application of opioid drugs often causes gastrointestinal reactions,such as nausea,vomiting and delayed gastrointestinal function recovery,after examination.These adverse effects can seriously affect the quality of life of patients.AIM To observe the effect of modified ShengYangYiwei decoction on gastrointestinal function,related complications and immune function in patients with gastric cancer during and after painless gastroscopy.METHODS A total of 106 patients with gastric cancer,who were selected from January 2022 to September 2022 in Xiamen Traditional Chinese Medicine Hospital for painless gastroscopy,were randomly divided into a treatment group(n=56)and a control group(n=50).Before the examination,all patients fasted for 8 h,provided their health education,and confirmed if there were contraindications to anesthesia and gastroscopy.During the examination,the patients were placed in the left decubitus position,the patients were given oxygen through a nasal catheter(6 L/min),the welling needle was opened for the venous channel,and a multifunction detector was connected for monitoring electrocardiogram,oxygen saturation,blood pressure,etc.Naporphl and propofol propofol protocols were used for routine anesthesia.Before anesthesia administration,the patients underwent several deep breathing exercises,received intravenous nalbuphine[0.nalbuphine(0.025 mg/kg)],followed by intravenous propofol[1.propofol(1.5 mg/kg)]until the palpebral reflex disappeared,and after no response,gastroscopy was performed.If palpebral reflex disappeared,and after no response,gastroscopy was performed.If any patient developed movement,frowning,or hemodynamic changes during the operation(heart rate changes during the operation(heart rate increased to>20 beats/min,systolic blood pressure increased to>20%of the base value),additional propofol[0.propofol(0.5 mg/kg)]was added until the patient was sedated again.The patients in the treatment group began to take the preventive intervention of Modified ShengYangYiwei decoction one week before the examination,while the patients in the control group received routine gastrointestinal endoscopy.The patients in the two groups were examined by conventional painless gastroscopy,and the characteristics of the painless gastroscopies of the patients in the two groups were recorded and compared.These characteristics included the total dosage of propofol during the examination,the incidence of complications during the operation,the time of patients'awakening,the time of independent activities,and the gastrointestinal function of the patients after examination,such as the incidence of reactions such as malignant vomiting,abdominal distension and abdominal pain,as well as the differences in the levels of various immunological indicators and inflammatory factors before anesthesia induction(T0),after conscious extubation(T1)and 24 h after surgery(T2).RESULTS There was no difference in the patients’general information,American Society of Anesthesiologist classification or operation time between the two groups before treatment.In terms of painless gastroscopy,the total dosage of propofol in the treatment group was lower than that in the control group(P<0.05),and the time of awakening and autonomous activity was significantly faster than that in the control group(P<0.05).During the examination,the incidence of hypoxemia,hypotension and hiccups in the treatment group was significantly lower than that in the control group(P<0.01).In terms of gastrointestinal function,the incidences of nausea,vomiting,abdominal distension and abdominal pain in the treatment group after examination were significantly lower than those in the control group(P<0.01).In terms of immune function,in both groups,the number of CD4+and CD8+cells decreased significantly(P<0.05),and the number of natural killer cells increased significantly(P<0.05)at T1 and T2,compared with T0.The number of CD4+and CD8+cells in the treatment group at the T1 and T2 time points was higher than that in the control group(P<0.05),while the number of natural killer cells was lower than that in the control group(P<0.05).In terms of inflammatory factors,compared with T0,the levels of interleukin(IL)-6 and tumor necrosis factor-alpha in patients in the two groups at T1 and T2 increased significantly and then decreased(P<0.05).The level of IL-6 at T1 and T2 in the treatment group was lower than that in the control group(P<0.05).CONCLUSION The preoperative use of modified ShengYangYiwei decoction can optimize the anesthesia program during painless gastroscopy,improve the gastrointestinal function of patients after the operation,reduce the occurrence of examination-related complications.展开更多

Diverse bacteria contain cGAS-like enzymes that produce cyclic oligonucleotides and induce antiphageactivity, known as CBASS. However, this activity has only been demonstrated through heterologous expression. Whetherbacteria harboring CBASS antagonize and co-evolve with phages is unknown. Here, we identified an endogenous cGAS-likeenzyme in Pseudomonas aeruginosa that generates 3',3'-cGAMP during phage infection, signals to a phospholipase effector, andlimits phage replication. In response, phages express an anti-CBASS protein ("Acb2") that forms a hexamer with three 3',3'-cGAMP molecules and reduces phospholipase activity. Acb2 also binds to molecules produced by other bacterial cGAS-likeenzymes (3',3'-cUU/UA/UG/AA) and mammalian cGAS (2',3'-cGAMP), suggesting broad inhibition of cGAS-based immunity.Upon Acb2 deletion, CBASS blocks lytic phage replication and lysogenic induction, but rare phages evade CBASS through majorcapsid gene mutations. Altogether, we demonstrate endogenous CBASS anti-phage function and strategies of CBASS inhibitionand evasion.展开更多

Methods Forty-nine Kashin-Beck patients in endemic area aged 13-16 years were divided into two groups and were orally given either selenized yeast or sodium selenite to provide 200 μ g selenium per day for 12 weeks. Erythrocyte selenium level, glutathione peroxidase activity, the rosette formation rates of red blood cells complement receptor typeⅠ(CR1), the immune function of red blood cells, and circulating immune complexes(CIC) were determined. Results After supplementing with selenium for 12 weeks, erythrocyte selenium level, glutathione peroxidase activity, the rosette formation rates of red blood cells CR1 were significantly increased. But the difference in rosette formation rates of IC and CIC content was not significant between before and after Se supplementation. Conclusion The increase of the immune function of the erythrocyte by selenium-supplement may be one of the effective mechanisms for the prevention of Kashin-Beck disease.展开更多

文摘In this study,we investigated the effects of major royal jelly proteins(MRJPs)on the estrogen,gut microbiota,and immunological responses in mice.Mice given 250 or 500 mg/kg,not 125 mg/kg of MRJPs,enhanced the proliferation of splenocytes in response to mitogens.The splenocytes and mesenteric lymphocytes activated by T-cell mitogens(Con A and anti-CD3/CD28 antibodies)released high levels of IL-2 but low levels of IFN-γand IL-17A.The release of IL-4 was unaffected by MRJPs.Additionally,splenocytes and mesenteric lymphocytes activated by LPS were prevented by MRJPs at the same dose as that required for producing IL-1βand IL-6,two pro-inflammatory cytokines.The production of IL-1β,IL-6,and IFN-γwas negatively associated with estrogen levels,which were higher in the MRJP-treated animals than in the control group.Analysis of the gut microbiota revealed that feeding mice 250 mg/kg of MRJPs maintained the stability of the natural intestinal microflora of mice.Additionally,the LEf Se analysis identified biomarkers in the MRJP-treated mice,including Prevotella,Bacillales,Enterobacteriales,Gammaproteobacteria,Candidatus_Arthromitus,and Shigella.Our results showed that MRJPs are important components of royal jelly that modulate host immunity and hormone levels and help maintain gut microbiota stability.

文摘BACKGROUND Alzheimer’s disease(AD)is a serious disease causing human dementia and social problems.The quality of life and prognosis of AD patients have attracted much attention.The role of chronic immune inflammation in the pathogenesis of AD is becoming more and more important.AIM To study the relationship among cognitive dysfunction,abnormal cellular immune function,neuroimaging results and poor prognostic factors in patients.METHODS A retrospective analysis of 62 hospitalized patients clinical diagnosed with AD who were admitted to our hospital from November 2015 to November 2020.Collect cognitive dysfunction performance characteristics,laboratory test data and neuroimaging data from medical records within 24 h of admission,including Mini Mental State Examination Scale score,drawing clock test,blood T lymphocyte subsets,and neutrophils and lymphocyte ratio(NLR),disturbance of consciousness,extrapyramidal symptoms,electroencephalogram(EEG)and head nucleus magnetic spectroscopy(MRS)and other data.Multivariate logistic regression analysis was used to determine independent prog-nostic factors.the modified Rankin scale(mRS)was used to determine whether the prognosis was good.The correlation between drug treatment and prognostic mRS score was tested by the rank sum test.RESULTS Univariate analysis showed that abnormal cellular immune function,extrapyramidal symptoms,obvious disturbance of consciousness,abnormal EEG,increased NLR,abnormal MRS,and complicated pneumonia were related to the poor prognosis of AD patients.Multivariate logistic regression analysis showed that the decrease in the proportion of T lym-phocytes in the blood after abnormal cellular immune function(odd ratio:2.078,95%confidence interval:1.156-3.986,P<0.05)was an independent risk factor for predicting the poor prognosis of AD.The number of days of donepezil treatment to improve cognitive function was negatively correlated with mRS score(r=0.578,P<0.05).CONCLUSION The decrease in the proportion of T lymphocytes may have predictive value for the poor prognosis of AD.It is recommended that the proportion of T lymphocytes<55%is used as the cut-off threshold for predicting the poor prog-nosis of AD.The early and continuous drug treatment is associated with a good prognosis.
文摘BACKGROUND Colon cancer(CC)has a high incidence rate.Radical resection is the main treatment method for CC;however,liver metastasis(LM)often occurs post-surgery.The liver contains both innate and adaptive immune cells that monitor and remove abnormal cells and pathogens.Before LM,tumor cells secrete cytokines and exosomes to adjust the immune microenvironment of the liver,thus forming an inhibitory immune microenvironment for colonization by circulating tumor cells.This indicates that the immune state of patients with CC plays a crucial role in the occurrence and progression of LM.AIM To observe and analyze the relationship between immune status and expression of tumor factors in patients with LM of CC,and to provide a scientific interven-tion method for promoting the patient prognosis.METHODS A retrospective analysis was performed.The baseline data of 100 patients with CC and 100 patients with CC who suffered from postoperative LM and were admitted to our hospital from May 2021 to May 2023 were included in the non-occurrence and occurrence groups,respectively.The immune status of the pa-tients and the expression of tumor factor-related indicators in the two groups were compared,and the predictive value of the indicators for postoperative LM in patients with CC was analyzed.RESULTS Compared with the non-occurrence group,the expression of serum carcinoem-bryonic antigen(CEA),CA19-9,CA242,CA72-4 and CA50 in patients in the occurrence group were significantly higher,while the expression of CD3+,CD4+,CD8+,natural killer(NK)and CD4+/CD25 in patients in the occurrence group were significantly lower(P<0.05).No significant difference was observed in other baseline data between groups(P>0.05).Multivariate logistic regression model analysis revealed that the expressions of CEA,CA19-9,CA242,CA72-4,CA50,CD3+,CD4+,CD8+,NK,and CD4+/CD25 were associated with the LM in patients with CC.High expressions of serum CEA,CA19-9,CA242,CA72-4 and CA50,and low expressions of CD3+,CD4+,CD8+,NK,and CD4+/CD25 in patients with CC were risk factors for LM(OR>1,P<0.05).The receiver operating characteristic curve showed that the area under curve for CEA,CA19-9,CA242,CA72-4,CA50,CD3+,CD4+,CD8+,NK,and CD4+/CD25 in the prediction of LM in patients with CC were all>0.80,with a high predictive value.CONCLUSION The expression of tumor factors and immune state-related indices in patients with CC is closely associated with the occurrence of LM.

文摘Background:In China,cage systems with a high space utilization have gradually replaced ground litter systems,but the disease incidence of chickens in cages is higher.Broilers in the ground litter pens may be stimulated by more environmental microbes during the growth process and show strong immune function and status,but knowledge of which microbes and their metabolites play an immunomodulatory role is still limited.This study aimed to explore the differences and correlations in the immune function,gut microbiota and metabolites and the importance of gut microbiota of broilers raised in cages and ground litter pens.Methods:The experiment involved a 2×2 factorial arrangement,with rearing systems(cages or ground litter pens)and antibiotic treatment(with or without broad-spectrum antibiotics in drinking water)as factors.Results:The results showed that,compared with the cage group,the ground litter broilers had stronger nonspecific immune function(Macrophages%and NO in blood),humoral immune function(IgG in blood,LPS stimulation index in ileum)and cellular immune function(T%,Tc%,ConA stimulation index and cytokines in blood).Antibiotic(ABX)treat-ment significantly reduced nonspecific immune function(Macrophages%and NO in blood,iNOS and Mucin2 mRNA expression in ileum),humoral immune function(IgG in blood and sIgA in ileum)and cellular immune function(T%and cytokines in blood,Th and Tc ratio,TLRs and cytokines mRNA expression in ileum).Furthermore,the ground litter broil-ers had higherαdiversity of microbiota in ileum.The relative abundance of Staphylococcus,Jeotgalicoccus,Jeotgalibaca and Pediococcus in the ileum of ground litter broilers were higher.ABX treatment significantly reduced theαdiversity of ileal microbiota,with less Chloroplast and Mitochondria.In addition,the levels of acetic acid,isobutyric acid,kynurenic acid and allolithocholic acid in the ileum of ground litter broilers were higher.Spearman correlation analysis showed that Jeotgalibaca,Pediococcus,acetic acid,kynurenic acid and allolithocholic acid were related to the immune function.Conclusions:There were more potential pathogens,litter breeding bacteria,short-chain fatty acids,kynurenine,allolithocholic acid and tryptophan metabolites in the ileum of broilers in ground litter pens,which may be the reason for its stronger immune function and status.

文摘BACKGROUND Painless gastroenteroscopy is a widely developed diagnostic and treatment technology in clinical practice.It is of great significance in the clinical diagnosis,treatment,follow-up review and other aspects of gastric cancer patients.The application of anesthesia techniques during manipulation can be effective in reducing patient fear and discomfort.In clinical work,the adverse drug reactions of anesthesia regimens and the risk of serious adverse drug reactions are increased with the increase in propofol application dose application dose;the application of opioid drugs often causes gastrointestinal reactions,such as nausea,vomiting and delayed gastrointestinal function recovery,after examination.These adverse effects can seriously affect the quality of life of patients.AIM To observe the effect of modified ShengYangYiwei decoction on gastrointestinal function,related complications and immune function in patients with gastric cancer during and after painless gastroscopy.METHODS A total of 106 patients with gastric cancer,who were selected from January 2022 to September 2022 in Xiamen Traditional Chinese Medicine Hospital for painless gastroscopy,were randomly divided into a treatment group(n=56)and a control group(n=50).Before the examination,all patients fasted for 8 h,provided their health education,and confirmed if there were contraindications to anesthesia and gastroscopy.During the examination,the patients were placed in the left decubitus position,the patients were given oxygen through a nasal catheter(6 L/min),the welling needle was opened for the venous channel,and a multifunction detector was connected for monitoring electrocardiogram,oxygen saturation,blood pressure,etc.Naporphl and propofol propofol protocols were used for routine anesthesia.Before anesthesia administration,the patients underwent several deep breathing exercises,received intravenous nalbuphine[0.nalbuphine(0.025 mg/kg)],followed by intravenous propofol[1.propofol(1.5 mg/kg)]until the palpebral reflex disappeared,and after no response,gastroscopy was performed.If palpebral reflex disappeared,and after no response,gastroscopy was performed.If any patient developed movement,frowning,or hemodynamic changes during the operation(heart rate changes during the operation(heart rate increased to>20 beats/min,systolic blood pressure increased to>20%of the base value),additional propofol[0.propofol(0.5 mg/kg)]was added until the patient was sedated again.The patients in the treatment group began to take the preventive intervention of Modified ShengYangYiwei decoction one week before the examination,while the patients in the control group received routine gastrointestinal endoscopy.The patients in the two groups were examined by conventional painless gastroscopy,and the characteristics of the painless gastroscopies of the patients in the two groups were recorded and compared.These characteristics included the total dosage of propofol during the examination,the incidence of complications during the operation,the time of patients'awakening,the time of independent activities,and the gastrointestinal function of the patients after examination,such as the incidence of reactions such as malignant vomiting,abdominal distension and abdominal pain,as well as the differences in the levels of various immunological indicators and inflammatory factors before anesthesia induction(T0),after conscious extubation(T1)and 24 h after surgery(T2).RESULTS There was no difference in the patients’general information,American Society of Anesthesiologist classification or operation time between the two groups before treatment.In terms of painless gastroscopy,the total dosage of propofol in the treatment group was lower than that in the control group(P<0.05),and the time of awakening and autonomous activity was significantly faster than that in the control group(P<0.05).During the examination,the incidence of hypoxemia,hypotension and hiccups in the treatment group was significantly lower than that in the control group(P<0.01).In terms of gastrointestinal function,the incidences of nausea,vomiting,abdominal distension and abdominal pain in the treatment group after examination were significantly lower than those in the control group(P<0.01).In terms of immune function,in both groups,the number of CD4+and CD8+cells decreased significantly(P<0.05),and the number of natural killer cells increased significantly(P<0.05)at T1 and T2,compared with T0.The number of CD4+and CD8+cells in the treatment group at the T1 and T2 time points was higher than that in the control group(P<0.05),while the number of natural killer cells was lower than that in the control group(P<0.05).In terms of inflammatory factors,compared with T0,the levels of interleukin(IL)-6 and tumor necrosis factor-alpha in patients in the two groups at T1 and T2 increased significantly and then decreased(P<0.05).The level of IL-6 at T1 and T2 in the treatment group was lower than that in the control group(P<0.05).CONCLUSION The preoperative use of modified ShengYangYiwei decoction can optimize the anesthesia program during painless gastroscopy,improve the gastrointestinal function of patients after the operation,reduce the occurrence of examination-related complications.
文摘A fundamental strategy of eukaryotic antiviral immunity involves the cGAS enzyme, which synthesizes 2',3'-cGAMP andactivates the effector STING. Diverse bacteria contain cGAS-like enzymes that produce cyclic oligonucleotides and induce antiphageactivity, known as CBASS. However, this activity has only been demonstrated through heterologous expression. Whetherbacteria harboring CBASS antagonize and co-evolve with phages is unknown. Here, we identified an endogenous cGAS-likeenzyme in Pseudomonas aeruginosa that generates 3',3'-cGAMP during phage infection, signals to a phospholipase effector, andlimits phage replication. In response, phages express an anti-CBASS protein ("Acb2") that forms a hexamer with three 3',3'-cGAMP molecules and reduces phospholipase activity. Acb2 also binds to molecules produced by other bacterial cGAS-likeenzymes (3',3'-cUU/UA/UG/AA) and mammalian cGAS (2',3'-cGAMP), suggesting broad inhibition of cGAS-based immunity.Upon Acb2 deletion, CBASS blocks lytic phage replication and lysogenic induction, but rare phages evade CBASS through majorcapsid gene mutations. Altogether, we demonstrate endogenous CBASS anti-phage function and strategies of CBASS inhibitionand evasion.

文摘Background:Soya saponin(SS),an active compound in soybean meals,has been widely studied in the medical field.However,it was considered as an anti-nutritional factor in poultry diets.The objective of this experiment was to measure the effects of dietary SS using three dietary treatments on egg-laying performance and immune function of laying hens.Birds were fed a low soybean meal basal diet(CON),a low-SS diet(50 SS)containing 50mg/kg SS,or a high-SS diet(500 SS)containing 500 mg/kg SS for 10 weeks.At the end of the 5th and 10th week of the trial,samples were collected for analysis.Results:Results showed that with 50 mg/kg SS supplementation,the egg production rate,feed conversion ratio(FCR),and eggshell quality tended to be improved.Serum follicle stimulating hormone(FSH)and Interleukin-4(IL-4)levels were also elevated as well as the peripheral blood LPS stimulation index,the proportion of B lymphocytes,and antibody titer of bovine serum albumin(BSA).We also found that mRNA levels of follicle stimulating hormone receptor(FSHR)in ovarian,nuclear transcription factor kappa B(NF-κB),Transforming growth factor(TGF-β)and interferonγ(IFN-γ)in spleen were up-regulated at the end of the trial.Additionally,dietary 50 mg/kg SS improved the ileal flora via up-regulating the relative abundance of Lactobacillus,Romboutsia and Lactobacillus delbrueckii.Although the immune related indicators were improved with 500 mg/kg SS supplemented,it seemed to have a negative influence on the laying-performance.Specifically,serum alanine aminotransferase(ALT),alkaline phosphatase(ALP),and the ratio of IFN-γto IL-4 were increased in the 500 SS group at the end of the trial.The m RNA levels of gonadotropin releasing hormone 1(GnRH1)in Hypothalamus,the estrogen related receptor(ERR)in ovaries were downregulated as well as the egg production rate during the trial with 500 mg/kg SS supplemented.Conclusions:The egg production performance was improved by dietary supplemented with 50 mg/kg SS via increasing ovarian FSHR transcription level and serum estrogen level.A beneficial shift in intestinal microflora was recorded,and the immune function of laying hens was also improved with 50 mg/kg SS supplementation.Surprisingly,the long-term supplementation of 500 mg/kg SS exerted a negative impact on the laying performance and physiological functions of the liver of laying hens.

文摘Previous study have demonstrated that a compound composed of water-soluable Ganoderma lucidum polysaccharides(GLP)and Polyporus umbellatus polysaccharides(PUP)in a ratio of 3:1 named GPP enhances innate immune function in mice through enhancing the function of macrophage cells and activity of natural killer(NK)cells.Here in our research,we further investigated the effect of GPP on the diversity and composition of intestinal flora,and explored its effect on colitis model mice.The immunoregulatory verification experiments of GPP were conducted in both normal and DSS-induced mice model.Our research showed that GPP increased the diversity of intestinal microorganisms in mice with the extension of administration time.Daily GPP intake attenuated DSS-induced colon injury,protected the splenic lymphocyte proliferation ability,enhanced the serum hemolysin synthesis,and increased peripheral phagocytes and NK cell activity in model mice.Comparisons of the predominant gene pathways of the bacterial microbiota showed that DNA repair and recombination,base mismatch repair pathways was stronger in GPP-treatment group than in control group,indicating the possible molecular mechanisms of immune function regulation.Our study showed that GPP regulated immune function in both health and colitis model,and had a positive effect on maintaining intestinal flora homeostasis.
文摘Objective:To examine the effects of Astragalus polysaccharide on immune function in B16 melanoma mice.Method:Forty male C57BL/6 mice were divided equally into a control group,model group,Astragalus polysaccharide low-dose group,and Astragalus polysaccharide high-dose group,with 10 mice per group.B16 cells were used to develop a mouse model of melanoma.After B16 engraftment,40 mg/kg and 80 mg/kg Astragalus polysaccharide was administered by gavage every day to the Astragalus polysaccharide low-dose group and Astragalus polysaccharide high-dose group,respectively.Splenic index,thymic index,tumor growth curves,and tumor inhibition rates were measured.Flow cytometry was used to measure proportions of peripheral blood T lymphocyte subsets.Hematoxylin and eosin staining was used to examine histopathological changes in tumors.Immunofluorescence double staining was used to identify myeloid-derived suppressor cells in tumor tissues.Results:In the Astragalus polysaccharide high-dose group,splenic and thymic indices were significantly increased and tumor growth was inhibited in melanoma mice.Flow cytometry demonstrated increased CD4^(+)and CD4^(+)/CD8^(+)T-cell ratios in the high-dose Astragalus polysaccharide group.HE staining demonstrated significantly decreased numbers of tumor cells among mice with melanoma in the high-dose Astragalus polysaccharide group.Immunofluorescence double staining demonstrated significantly decreased numbers of myeloid-derived suppressor cells in tumor tissues in the high-dose Astragalus polysaccharide group.Conclusion:Astragalus polysaccharide inhibits tumor growth,increases splenic and thymic indices,increases CD4^(+)and CD4^(+)/CD8^(+)T-cell ratios,and decreases myeloid-derived suppressor cell numbers in melanoma mice.Our results indicate Astragalus polysaccharide may enhance immune function resulting in inhibition of tumorigenesis and tumor progression.

文摘Objective To investigate the relationship between erythrocyte immune function and selenium (Se) level. Methods Forty-nine Kashin-Beck patients in endemic area aged 13-16 years were divided into two groups and were orally given either selenized yeast or sodium selenite to provide 200 μ g selenium per day for 12 weeks. Erythrocyte selenium level, glutathione peroxidase activity, the rosette formation rates of red blood cells complement receptor typeⅠ(CR1), the immune function of red blood cells, and circulating immune complexes(CIC) were determined. Results After supplementing with selenium for 12 weeks, erythrocyte selenium level, glutathione peroxidase activity, the rosette formation rates of red blood cells CR1 were significantly increased. But the difference in rosette formation rates of IC and CIC content was not significant between before and after Se supplementation. Conclusion The increase of the immune function of the erythrocyte by selenium-supplement may be one of the effective mechanisms for the prevention of Kashin-Beck disease.
