Chinese Journal of Immunology 1985;0(01):-
The concentration of the cyclic nucleotides and its relation with the E-RFC were determined by using ginseng rhizome saponin in human peripharal leukocytes.Result were compared with the ckange of the E-RFC by using cAMP.cGMP and theophylline. Experiments proved that girseng rhizome saponin mainly affected the lymphocytes and significantly increased the concentration of cAMP and cGMP,especially,the cAMP. Lymphocytes were incubated with ginseng rhizome saponin to form Et-RFC. It is different where lymphocytes were incubated in diffierent times. cAMP and theophylline reduced the Ea-RFC and Et-RFC, cGMP increased the Ea— RFC,but no effect to the Et-RFC. Ginseng rhizome or root saponin could promote the Ea-RFC,but inhibited the Et-RFC. It is consistent with the effect of both cAMP and cGMP. Experiments showed that ginseng rhizome saponin increased the concentration of cAMP and cGMP in human lyphocytes followed by that of E-RFC.It was suggested that the change of cyclic nucleotides in lymphocytes may be a mechanism of adjusting the immunity on cell level.

[Aim] The expressed system of sterol regulation by SCAP/SREBP Pathway was established in the oocyte of the Xenopus laevis and was applied to investigate the effect of cucurmin on the SREBP pathway.[Methods] The plasmid of PLXRN-4SRE-fpa was restructed and injected into the nucleus of Xenopus Oocytes in phase V or VI. The oocyte was incubated with different concentrations of the curcumin. After three days the fluorescence intensity on the membrane of the Oocytes was measured by Fluoroanalyzer.[Results] The fluoresecence intensity on the membrane of the oocyte increased with increasing of the concentration of the curcumin. The trail group which have all regulation elements of SCAP/SREBP pathway can express more fluorscence protein than the control group. [Conclusion] The experiment provides that the curcumin can upgrade the expression of low density lipoprotein receptor by SCAP/SREBP regulation pathway. The model can be applied for quick screening of the scap ligand drugs and inverstigating the mechanism of the drugs.

Objective Two-dimensional electrophoresis and mass spectrum were used to study the effects of Liuwei Dihuang Decoction on hepatic mitochondria proteome of kidney-yin deficiency rat induced by hyperthyrea. Methods The protein of liver mitochondria from kidney-yin deficiency rats and the kidney-yin deficiency rats treated with Liuwei Dihuang Decoction were isolated by two-dimensional electrophoresis, then stained with silver staining method. The gels were respectively imaged by UMAX ImageScanner and spot-features of proteome difference were analyzed by ImageMaster2D6.0 software. MALDI-TOF MS was used to identify the different protein with abundant changes more than 2 folder between normal rats and kidney-yin deficiency rats. Results In the treated group it was found that major urinary protein precursor, peroxiredoxin-6, endoplasmic reticulum protein 29 precursor, chain D rat transthyretin were increased, while 78 kDa glucos eregurated protein precursor, glutathione S-transferase Mu 1, 60 kDa heat shock protein, peptidyl-prolyl cis-trans isomerase, H~+ -transporting ATP synthase, nuclear factor kappa B 2, BNIP1 protein were decreased. Conclusion The mechanism of nourishing kidney-yin action of Liuwei Dihuang Decoction lies in its relieving energy metabolism, regulating inflammatory factorderangement and apoptosis inhibition, antagonizing free radical damage, enhancing gonadal hormone level by the down regulation of NF-κB, H~+-transporting ATP synthase, and the up-regulation of PDX6.

The blood and urine estrogen (E2) and progesterone (P) were measured in 133 patients with fibrocystic disease (FCD) of breast and 17 healthy subsjects during menstrual cycle phases. According to the characteristics of the secretion, the patients were divided into five types. Type A (54 patients): The secretion peak of E2 and P appeared beforehand and secretion of P was prolonged and E2 decreased significantly in ovulatory phase. Type B (16 patients): The secretion peak of E2 disappeared in ovulatory phase although the secretion of P was normal. Type C (16 patients): The secretion peak of P deferred its disappearance and maintained at higher level till pre-menstrual period and sc did E2: the secretion of E2 decreased in ovulatory phase. Type D (41 patients): The secretion peak of E2 in ovulatory phase was normal but could not return to normal level in pre-menstrual period, in the mean time the secretion of P also deferred its disappearance. Type E (6 patients): There was no secretion of P and the blood and urine concentrations of E2 deccreased in all phases. The average value of E2 in the patients with FCD was compared with that of healthy subjects. The concentration of E2 in all the patients increased in follicular and pre-menstrual phases. However, the concentration of E2 in ovulatory phase was much lower in the patients than in healthy subjects.

Objective:To observe the effect of Astragalus polysaccharides(APS) on inducing the cord blood monocytes into mature dendritic cells(DCs) in vitro and to investigate their morphous,cellar immunological characteristics,and contribution to T cell proliferation.Methods:①The cord blood monocytes were isolated by lymphocyte isolating solution under axenic condition,and three groups were divided.②Cells cultured with APS in concentration of 100 mg/L as the experiment group, that with the cytokines of GM-CSF/IL-4/TNF-? as the positive control, and another without either GM-CSF/IL-4/TNF-? or APS as the negative control, respectively. The morphology of DCs was identified by inverted optical microscope or scanning electron microscope. The phenotype of 12 days cultures of DCs(CD1a, CD80, CD86 and CD83) were identified by flowcytometry. The DCs preparations from the experiment group were treated with mitomycin for 45 min to remove their proliferative activity as incentive cells in the mixed cultures with allogenic peripheral blood mononuclear cells from healthy volunteers as responders. T cell proliferation induced with the DCs preparations was detected by MTT chromatometry.Results:After cultured for 72 hours, the cell of both the experiment group and the positive control grew dusteringly and began to change from round to irregularin shapes. The longer the cells were cultured, the more obvious the dendritic structure is. The cells of experiment group and the positive control group when cultured for 12 days had the most typical dendritic structure. The negative control group cells had no dendritic structure and became macrophages when cultured for 12 days. The experiment group cells cultured for 10 days showed typical dendritic morphology by SEM. The experiment group cells and the positive group cells cultured for 12 days significantly expressed high level of the phenotypes of DCs(CD1a, CD80, CD86 and CD83) by flowcytometry.And the difference exhibitied statistical significance when compared with the negative control group(P0.05).The mixed lymphocyte reaction showed that the DCs induced by APS trigerred proliferation of allogenic T cells obviously.Conclusion:Both APS and cytokine could induce the cord blood monocytes to differentiate into functional DCs committedly. DCs reduced by APS stimualate proliferation of the allogenic T cells obviously.
