Effect of Kuwanon G Isolated from the Root Bark of Morus alba on Ovalbumin‐induced Allergic Response in a Mouse Model of Asthma

The root bark of Morus alba L. (Mori Cortex Radicis; MCR) is traditionally used in Korean medicine for upper respiratory diseases. In this study, we investigated the antiasthmatic effect of kuwanon G isolated from MCR on ovalbumin (OVA)‐induced allergic asthma in mice. Kuwanon G (1 and 10 mg/kg) was administered orally in mice once a day for 7 days during OVA airway challenge. We measured the levels of OVA‐specific IgE and Th2 cytokines (IL‐4, IL‐5, and IL‐13) in the sera or bronchoalveolar lavage (BAL) fluids and also counted the immune cells in BAL fluids. Histopathological changes in the lung tissues were analyzed. Kuwanon G significantly decreased the levels of OVA‐specific IgE and IL‐4, IL‐5, and IL‐13 in the sera and BAL fluids of asthma mice. Kuwanon G reduced the numbers of inflammatory cells in the BAL fluids of asthma mice. Furthermore, the pathological feature of lungs including infiltration of inflammatory cells, thickened epithelium of bronchioles, mucus, and collagen accumulation was inhibited by kuwanon G. These results indicate that kuwanon G prevents the pathological progression of allergic asthma through the inhibition of lung destruction by inflammation and immune stimulation.

Protective Effects of Tannins in Sanguisorbae Radix on Myelosuppression Mice

Objective To explore the protective effects of tannins in Sanguisorba Radix(TSR) on myelosuppression mice induced by cyclophosphamide(CTX). Methods TSR was iggiven at the dose of 20 mg/kg for 10 d after ip administration of CTX(200 mg/kg). Results TSR could significantly increase the numbers of white blood cells, red blood cells, and platelets of myelosuppression in mice. And it could accelerate bone marrow haemopoietic stem/progenitor cells(HSPCs) in myelosuppression mice and enhance cell proliferation by promoting cell cycles from G0/G1 phase to access into S and G2/M phases, then the reduced number of HSPCs induced by CTX was reversed. Moreover, TSR could increase the mRNA and protein expression levels of O(6)-methylguanine-DNA methyltransferase(MGMT) in HSPCs of myelosuppression mice. Conclsion TSRhas a protective function against CTX-induced myelosuppression. The mechanism might be related to protecting hematopoietic stem cells of bone marrow, stimulating hematopoiesis recovery, as well as preventing the apoptosis of hematopoietic stem cells induced by CTX.

Anti-inflammatory activity of Lychnophora passerina, Asteraceae (Brazilian "Arnica")

Aim of the study

Boehmeria nivea (L.) Gaud. was commonly used to treat miscarriages clinically. The aim of this study was to examine its safety for embryonic development.

Materials and methods

Pregnant mice were randomly assigned into 5 groups, i.e. mice were oral-treated with distilled water (G1), with Boehmeria nivea extract of 2, 8 or 32 g/kg/day (G2, G3 or G4), and with 3 doses of vitamin A of 200,000 IU/kg as positive controls (G5). Meanwhile, IC₅₀ values for both embryonic stem cells (ESCs) and 3T3 cells were detected by cytotoxicity assays.

Results

(1) The resorptions and malformed fetuses in G5 were significantly higher than G1 (P < 0.001), whereas the maternal body-weight and uterus-weight were lower than G1 (P < 0.05); (2) there was no difference in the fetal body-weight, maternal relative body-weight gain, liver-, kidney- or heart-weight, relative organ-weight, and histological examination among five groups; (3) there was no difference in IC₅₀ values between ESCs and 3T3 cells, but high concentration of Boehmeria nivea extract might significantly lower ESCs’ viability (P < 0.05).

Conclusion

Boehmeria nivea extract at 32 g/kg/day did not cause significant embryotoxicity or maternal toxicity in mice, although it might cause cytotoxicity in cultured ESCs at a high dose.

Piperine,a Pungent Alkaloid from Black Pepper,Inhibits B Lymphocyte Activation and Effector Functions

Piperine has several well‐documented anti‐inflammatory properties; however, little is known regarding its effect on humoral immunity. In this study, we describe the immunosuppressive effect of piperine on B lymphocytes, which are integral to the humoral immune response. Mouse B cells were cultured in the absence or presence of non‐cytotoxic concentrations (25, 50, and 100 μM) of piperine during T‐dependent or T‐independent stimulation. Piperine inhibited B cell proliferation by causing G0/G1 phase cell cycle arrest in association with reduced expression of cyclin D2 and D3. The inhibitory effect of piperine was not mediated through transient receptor potential vanilloid‐1 ion channel (TRPV1) because piperine also inhibited the proliferation of B cells from TRPV1‐deficient mice. Expression of class II major histocompatibility complex molecules and costimulatory CD40 and CD86 on B lymphocytes was reduced in the presence of piperine, as was B cell‐mediated antigen presentation to syngeneic T cells. In addition, piperine inhibited B cell synthesis of interleukin (IL)‐6 and IL‐10 cytokines, as well as IgM, IgG2b, and IgG3 immunoglobulins. The inhibitory effect of piperine on B lymphocyte activation and effector function warrants further investigation for possible application in the treatment of pathologies related to inappropriate humoral immune responses.

氧化苦参碱延长小鼠异体移植心肌存活期及其免疫机理的研究

本实验观察到肌肉注射氧化苦参碱具有明显延长小鼠异体游离移植心肌存活期的作用,并随剂量加大其作用增强。检查药物对移植和非移植小鼠的脾脏淋巴细胞转化和免疫球蛋白分泌细胞的影响。实验发现,移植术后10天小鼠体外脾脏细胞自发增殖增强,对刀豆蛋白 A(ConA)刺激的转化反应则明显减弱。氧化苦参碱显著抑制正常小鼠的脾细胞的自发增殖及对 ConA 或脂多糖(LPS)刺激的转化反应,而对手术已使之显著降低的脾细胞对 ConA 刺激的转化反应无影响。这种选择性抑制作用可能利于避免用其他常规非特异免疫抑制剂所带来的危害。
