OBJECTIVEAging is associated with the development of diseases because of immunosuppression and altered functioning of the neuroendocrine system. The medicinal properties of Morinda citrifolia L. have been widely exploited for the treatment of age-associated diseases. This study aims to investigate the in vitro and in vivo effects of noni (M. citrifolia) fruit juice (NFJ) on neuro-immunomodulation in the lymph node lymphocytes of F344 rats.

METHODSLymphocytes isolated from axillary and inguinal lymph nodes of young (3-4 months) and old (18-21 months) rats were treated in vitro with different concentrations (0.0001%, 0.01%, and 1%) of NFJ for a period of 24 h. In the in vivo study, old (16-17 months) male F344 rats were treated with 5 mL/kg body weight of 5%, 10% and 20% of NFJ, twice a day, by oral gavage, and lymph node lymphocytes were isolated after 60 d. Concanavalin A (Con A)-induced lymphocyte proliferation, interleukin-2 (IL-2) and interferon-γ (IFN-γ) production and expression of intracellular markers, such as phospho-extracellular signal-regulated kinase (p-ERK1/2), phospho-cAMP response element-binding protein, phospho-protein kinase B (p-Akt), phospho-tyrosine hydroxylase (p-TH), phospho-nuclear factor of κ light polypeptide gene enhancer in B-cells inhibitor-α (p-IκB-α) and phospho-nuclear factor-κB (p-NF-κB p65 and p50) were examined in the lymphocytes of lymph nodes.

RESULTSNFJ increased Con A-induced lymphocyte proliferation, IL-2 and IFN-γ production, and p-ERK1/2 expression both in vitro and in vivo. In in vivo NFJ-treated old rats, lymph node lymphocytes showed increased expression of p-TH and Akt, nitric oxide production and decreased expression of p-NF-κB p65 and p50.

CONCLUSIONThese results suggest that the immunostimulatory properties of NFJ are facilitated through intracellular signaling pathways involving ERK1/2, Akt and NF-κB.

OBJECTIVETo investigate the effects of Morina Officinalis How (MOH) on the abnormal levels of serum luteotrophic hormone (LH) and LH receptor (LHR) in the testis tissue induced by cellphone radiation (CPR) in rats.

METHODSFifty adult male SD rats were randomly divided into five groups of equal number: sham CPR, untreated CPR, negative double distilled water (DDW) control, aqueous MOH extract, and alcohol MOH extract. All the animals were exposed to mobile phone radiation except those of the sham CPR group. Then, the rats of the latter two groups were treated intragastrically with MOH at 20 g per kg of the body weight per day in water and alcohol, respectively. After 2. weeks of treatment, all the rats were sacrificed for measurement of the levels of serum LH and LHR in the testis tissue.

RESULTSThe levels of serum LH and LHR were 30.15 ± 8.71 and 33.28 ± 6.61 in the aqueous MOH group and 0.96 ± 0.06 and 0.94 ± 0.08 in the alcohol MOH group, both significantly decreased as compared with the negative DDW controls (P < 0.05), but with no remarkable difference between the two MOH groups (P > 0.05).

CONCLUSIONMOH can improve CPR-induced abnormality of LH and LHR in adult male rats.

OBJECTIVETo study the effect of Morinda officinalis (MO) extract on cytoxan (CTX) -impaired spermatogenesis of adult male SD rats.

METHODSWe randomly divided 56 adult male SD rats into seven groups of equal number: blank control, CTX model, CTX + NS, CTX + 10 g/kg MO, CTX + 20 g/kg MO, CTX + 30 g/kg MO, and CTX + 40 g/kg MO. We made the models of impaired spermatogenesis in the SD rats by intraperitoneal injection of CTX and treated the animal models by intragastric administration of MO at the concentrations of 10, 20, 30, and 40 g per kg per d, respectively. After two weeks of medication, we observed the changes in the body weight, testicular and epididymal indexes, and microstructure of the testis tissue, measured the mean seminiferous tubule diameter (MSTD) , and obtained testicular biopsy scores (TBS) in different groups, followed by comparative analyses.

RESULTSAfter treatment, the CTX + NS group showed no remarkable differences in the body weight ([234.83 ± 28.77] g) and epididymal index (2.71 ± 0.34) from those of the four CTX + MO groups, but exhibited a significantly lower testicular index ([12.15 ± 1.04] g) than those in the CTX + 20 g/kg MO ([13.71 ± 0.97] g), CTX + 30 g/kg MO, ([13.30 ± 0.29] g), and CTX + 40 g/kg MO group ([13.48 ± 0.51] g) (P < 0.05). Light microscopy revealed obvious pathological changes of the testis tissue in the CTX + NS group and significantly ameliorated structures of the seminiferous tubules in the CTX + MO 10, 20, 30, and 40 g/kg groups, with the MSTD of (204.78 ± 11.03), (216.55 ± 10.93), (218.03 ± 11.23), and (218.59 ± 14.06) μm, respectively, and the TBS of 9.03 ± 0.39, 9.69 ± 0.26, 9.83 ± 0.18, and 9.89 ± 0.11, respectively, all significantly higher than (189.74 ± 8.55) μm and 5.95 ± 1.21 in the CTX + NS group (P < 0.05). The efficacy of MO extract was increased in a concentration-dependent manner.

CONCLUSIONMorinda officinalis extract can repair cytoxan-induced damage to rat spermatogenesis, with may achieve the best effect at the concentrations of 30 and 40 g per kg per d.

To study the in situ intestinal absorption of five oligosaccharides contained in Morinda officinalis How. (sucrose, kestose, nystose, 1F-Fructofuranosyinystose and Bajijiasu). The absorption of the five oligosaccharides in small intestine (duodenum, jejunum and ileum) and colon of rats and their contents were investigated by using in situ single-pass perfusion model and HPLC-ELSD. The effects of drug concentration, pH in perfusate and P-glycoprotein inhibitor on the intestinal absorption were investigated to define the intestinal absorption mechanism of the five oligosaccharides in rats. According to the results, all of the five oligosaccharides were absorbed in the whole intestine, and their absorption rates were affected by the pH of the perfusion solution, drug concentration and intestinal segments. Verapamil Hydrochloride could significantly increase the absorptive amount of sucrose and Bajijiasu, suggesting sucrose and Bajijiasu are P-gp's substrate. The five oligosaccharides are absorbed mainly through passive diffusion in the intestinal segments, without saturated absorption. They are absorbed well in all intestines and mainly in duodenum and jejunum.

To investigate the intervention effects of Morinda officinalis How. on 'Kidney-yang deficiency syndrome' induced by hydrocortisone in rats, the metabolic profiles of rat urine were characterized using proton nuclear magnetic resonance and principal component analysis (PCA) was applied to study the trajectory of urinary metabolic phenotype of rats with 'Kidney-yang deficiency syndrome' under administration of M. officinalis at different time points. Meanwhile, the intervention effects of M. officinalis on urinary metabolic potential biomarkers associated with 'Kidney-yang deficiency syndrome' were also discussed. The experimental results showed that in accordance to the increased time of administration, an obvious tendency was observed that clustering of the treatment group moved gradually closed to that of the control group. Eight potential biomarkers including citrate, succinate, alpha-ketoglutarate, lactate, betaine, sarcosine, alanine and taurine were definitely up- or down-regulated. In conclusion, the effectiveness of M. oficinalis on 'Kidney-yang deficiency syndrome' is proved using the established metabonomic method and the regulated metabolic pathways involve energy metabolism, transmethylation and transportation of amine. Meanwhile, the administration of M. officinalis can alleviate the kidney impairment induced by 'Kidney-yang deficiency syndrome'.

Chuankezhi (CKZ), a new Chinese medicine, plays an important role in immunoregulation. Cytokine-induced killer (CIK) cells have been commonly used for immunotherapy in recent years. In this study, we aimed to investigate the immunoregulatory effect of CKZ on CIK cells. Peripheral blood monocytes were isolated from healthy donors, and CIK cells were generated by culturing monocytes with interferon-gamma (IFN-γ) and interleukin 2. Different concentrations of CKZ were added on day 2. After incubation for 14 days in culture, the antitumor effects of CIK cells were measured by cytotoxicity assay. Flow cytometry was used to explore the effect of CKZ on CIK cell immunophenotype, intracellular cytokine production, and apoptosis. The effect of CKZ on the antitumor activity of CIK cells in nude mice was also investigated. CKZ increased the percentage of CD3+CD56+ CIK cells but did not significantly change the percentage of CD4+, CD8+, or CD4+CD25+ CIK cells. CKZ-conditioned CIK cells showed a greater ability to kill tumor cells, as well as a higher frequency of IFN-γ and TNF-α production, compared with the CIK cells in the control group. CKZ also suppressed the apoptosis of CIK cells in vitro. Furthermore, CKZ combined with CIK cells had a stronger suppressive effect on tumor growth in vivo than the CIK, CKZ, or normal saline control groups. Our results indicate that CKZ enhances the antitumor activity of CIK cells and is a potential medicine for tumor immunotherapy.
