Abstract
Several monomers isolated from Tripterygium wilfordii Hook f. (Celastraceae) have attracted worldwide interest. In this study, we established a simple and reliable kidney transplantation model in beagle dog to evaluate the immunosuppressive activity of demethylzeylasteral (T-96), an immunosuppressive monomer isolated from the root xylem of T. wilfordii. Recipient and donor male beagle dogs were obtained from two different breeders to ensure MHC mismatching. All dogs were randomly divided into six groups following kidney transplantation, and different doses of T-96 or cyclosporine A (CsA) were administered to each group during 14 days of observation. The results showed that T-96 alone at a dosage of 10 or 20 mg/kg/day prolonged graft survival up to 10.83 ± 1.47 or 11.17 ± 1.47 days. A combination of T-96 and CsA significantly prolonged the survival time to 13.33 ± 1.75 days. The results demonstrated that T-96 can inhibit acute rejection in kidney transplantation, and the inhibitory effect of T-96 was enhanced when combined with CsA, which suggests the possible use in organ transplantation to prevent immune rejection.

JOURNAL OF ETHNOPHARMACOLOGY 2011; 137:1381-1387. [PMID: 21855621 DOI: 10.1016/j.jep.2011.08.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2011] [Revised: 08/01/2011] [Accepted: 08/02/2011] [Indexed: 05/31/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The fruit of Thladiantha dubia has been used in Chinese manchu nationality folk medicine for treatment of various pains, such as rheumatic pain, lumbocrural pain, and dysmenorrhea. The aim of the present study was to evaluate the anti-rheumatic effect of Thladiantha dubia fruit crude polysaccharide (TF-P) fraction in rats. MATERIALS AND METHODS TF-P was evaluated in mice for analgesic activity using acetic acid-induced abdominal contractions test and for anti-inflammatory activity using xylene-induced ear oedema model. Moreover, rheumatoid arthritis (RA) was induced by injection of CFA into the subplantar surface of the hind paw of the male Wistar rats. Joint swelling was measured. In order to evaluate the effect of TF-P on disease progression, proinflammatory mediators (TNF-α and IL-2), and antioxidant indicators (SOD, MDA, and NO) were determined in rats induced by CFA. Pathologic changes of RA in rats were also observed under light microscope. RESULTS AND CONCLUSIONS In the present study, TF-P at the dose of 200mg/kg (according to the clinical traditional dosage) significantly reduced writhings and stretchings induced by the acetic acid in mice. TF-P significantly inhibited xylene-induced ear oedema in mice, compared with control group. TF-P significantly inhibited inoculated and non-inoculated joint swellings in rats induced by CFA. TF-P had no effect of body weight in rats. The histopathological analysis suggested that TF-P obviously alleviated the degree of RA rats. TF-P treated rats preserved a nearly normal histological architecture of the joint. Results of the present study confirm the use of Thladiantha dubia traditionally for the treatment of painful and inflammatory conditions. Those results suggest TF-P has protective and therapeutic effects on RA rats induced by CFA.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease with higher morbidity and mortality among ethnic Chinese patients than Whites. Corticosteroid and other immunosuppressive drugs, including cyclophosphamide, azathioprine, and hydroxychloroquine are traditional therapies for this disease. Since the year 2000, mycophenolate mofetil and rituximab have been widely used in refractory SLE or severe lupus nephritis. Because the high disease activity remains, even after active therapy, and serious side effects from Western medicines may develop, more than 40% of SLE patients in Western countries are pursuing complementary and alternative therapies (CATs). CAT remedies are multiplex, and include herbal medicines, diets and vitamins, acupuncture, chiropractice, folk medicine, massage, spiritual healing, etc. Many herbal formulas have been used but in general their efficacy in treating lupus is doubted because of the lack of strong evidence. Tripterygium (T2) has demonstrated good efficacy in rheumatoid arthritis (RA) and SLE, but widespread use is limited due to the side effects. Through randomized clinical trials, we hope in the future that some Chinese medicines may be found helpful as CATs for SLE.

Abstract
In this study, we examined the immunosuppressive activity of demethylzeylasteral (T-96), isolated from the traditional Chinese herbal medicine, Tripterygium wilfordii Hook f. Its immunosuppressive effect was investigated using mouse splenocytes in vitro, and in an in vivo rat kidney transplant model. T-96 inhibited mouse splenocyte proliferation in a dose dependent manner. In the rat kidney transplant study, rats were randomly divided into eight groups following kidney transplantation, and different doses of T-96 or cyclosporin A (CsA) were administered to each group. T-96 alone at doses of 10 or 20 mg/kg/day significantly prolonged the survival of kidney-transplanted rats, compared with transplanted but untreated control rats. A combination of T-96 and prednisone also significantly prolonged survival: 10 mg/kg/day T-96 with 10 mg/kg/day prednisone increased the survival time to 31.8+/-6.5 days. Moreover, the combination of T-96 and prednisone was also effective in suppressing rejection of rat transplanted kidneys. These results demonstrate the strong immunosuppressive activity of T-96 and suggest a possible clinical use for T-96 as an immunosuppressive agent in the fields of organ transplantation and autoimmune disorders.

Abstract
Prostaglandins (PGs) are active biologic substances that are involved in a wide range of physiologic processes; when their production is out of balance, they are factors in the pathogenesis of illness. Modulation of PGs by inhibition or stimulation is promising for the management of various conditions. PG inhibitors are widely used to relieve pain and inflammation in patients with rheumatologic disease. Interest in the use of PG inhibitors to prevent cancer and cardiovascular events is growing. More than 27 y ago, investigators found that PG depresses antibody production in vivo; reduces serum iron, hemoglobin, and leukoid series in bone marrow during acute and chronic blood loss; reduces albumin during antigenic stimulation; suppresses hypercalcemia after bleeding; and reduces fasting blood sugar and hyperglycemia after ether anesthesia and bleeding. Chronic conditions that produce large quantities of PGs are associated with immunosuppression and secondary anemia. Investigators in the present study hypothesized (1) that the overproduction of PGs is responsible for immunosuppression and secondary anemia in conditions associated with increased PG synthesis, such as pathologic inflammation, malignancy, trauma, and injury, and (2) that PG inhibitors reverse immunosuppression and secondary anemia, thereby enhancing the immune response. This is supported by many reports that show the immunosuppressive effects of PGs and their role in the immunosuppression associated with pathologic inflammation, burns, trauma, and tumors. Inhibition of PGs can be achieved through the use of synthetic medicines and natural products. This article reviews the effects of PGs and inhibition of increased synthesis of PGs on the lymphoid system, hematologic indices, and bone marrow elements in trauma, injury, burns, and tumors. The Medline database (1966-2006) was used in this study. Investigators in the present study and others have provided evidence that shows the involvement of PGs in immunosuppression and secondary anemia, as well as the efficacy of inhibited overproduction of PGs in many pathologic conditions other than rheumatologic disease.

Abstract
Background Extracts of Tripterygium wilfordii Hook F (TWHF), a traditional Chinese herb, have been reported to show efficacy in patients with rheumatoid arthritis (RA). Since RA is not only characterized by inflammation but also by synovial proliferation in the joints, we examined whether triptolide (a constituent of TWHF) could influence the proliferation of rheumatoid synovial fibroblasts (RSF) by induction of apoptosis. Results RSF were obtained from RA patients during surgery and were treated with triptolide under various conditions. The viability and proliferation of RSF were measured by the 4-[3-(4-iodophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate (WST-1) assay and by 5-bromo-2'-deoxyuridine incorporation, respectively. Apoptosis was identified by detection of DNA fragmentation using an enzyme-linked immunosorbent assay and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (TUNEL). The role of caspases in apoptosis of RSF was analyzed by measuring caspase-3 activity. Activation of the peroxisome proliferator-activated receptor (PPAR) γ was assessed by a luciferase reporter gene assay using RSF transfected with a plasmid containing the peroxisome proliferator response element. Triptolide decreased viability, inhibited proliferation, and induced apoptosis of RSF in a concentration-dependent manner at very low (nM) concentrations. Caspase-3 activity was increased by treatment with triptolide and was suppressed by caspase inhibitors. Although PPARγ activation was induced by 15-deoxy-Δ12,14-prostaglandin J2, triptolide did not induce it under the same experimental conditions. An extract of TWHF also induced DNA fragmentation in RSF. Conclusion The mechanism of action remains to be studied; however, triptolide may possibly have a disease-modifying effect in patients with RA.
