  • Angiogenesis is an essential process for the growth, invasion and metastasis of cancer. However, it is uncertain that antiangiogenic effects can be a major treatment strategy of oral cancer. The aim of this study was to investigate whether thalidomide, which is known to be a potent inhibitor of angiogenesis, have inhibitory effect on the growth and antiangiogenic effects of oral squamous cell carcinoma(OSCC) xenografted in nude mice and whether antiangiogenesis of thalidomide can be included as a major treatment strategy of oral cancer. After human oral squamous cell carcinoma strain KB was subcutaneously implanted in 20 nude mice, the volume of tumor was measured every three days. When the tumor mass reached $75{\sim}100mm^3$, thalidomide(200mg/kg/d) was administered into 10 experimental nude mice and the same volume of distilled water was administered into 10 control nude mice and the tumor volume was measured every three days. The excised tumor masses on the 30th day after administration were frozen and processed for immunohistochemistry using vascular endothelial growth factor(VEGF) and CD31. We evaluated microvessel density and VEGF expression. The results were as follows ; 1. Thalidomide retarded the growth of human OSCC as compared with the control group, but it was not statistically significant. 2. A statistically significant lower microvessel density was observed in the thalidomide-treated group than in the control group(p<0.01) and thalidomide significantly reduced VEGF expression (p<0.01). Thalidomide exhibited significantly antiangiogenic effect, but did not inhibit the growth of human OSCC effectively. Antiangiogenic therapy of thalidomide alone is not likely to be effective in the treatment of human OSCC, but might be regarded as adjuvant chemotherapeutic strategy.

  • For treating Leishmania major infection in BALB/c mice, we used thalidomide in conjunction with glucantime. Groups of mice were challenged with $5{\time}10^3$ metacyclic promastigotes of L. major subcutaneously. A week after the challenge, drug treatment was started and continued for 12 days. Thalidomide was orally administrated 30 mg/kg/day and glucantime was administrated intraperitoneally (200 mg/kg/day). It was shown that the combined therapy is more effective than single therapies with each one of the drugs since the foot pad swelling in the group of mice received thalidomide and glucantime was significantly decreased (0.9 :t 0.2 mm) compared to mice treated with either glucantime, thalidomide, or carrier alone (1.2 :t 0.25, 1.4 :t 0.3, and 1.7 :t 0.27 mm, respectively). Cytokine study showed that the effect of thalidomide was not dependent on IL-12; however, it up-regulated IFN-yand down-regulated IL-10 production. Conclusively, thalidomide seems promising as a conjunctive therapy with antimony in murine model of visceral leishmaniasis.

  • Background: Body fats, especially both of abdominal fat pad mass and skeletal muscle fat content, are inversely related to insulin action. Therefore, methods for decreasing visceral fat mass and muscle triglyceride content may be helpful for the prevention of insulin resistance. Methods: Thalidomide, used for its anti-angiogenic and anti-inflammatory properties, was administered to rats for 4 weeks. A 10% solution of thalidomide in dimethyl sulfoxide was injected daily into the peritoneal cavity as much as 100 mg/kg of body weight. Results: The total visceral fat pad mass in the thalidomide-treated group was 11% lower than in the control group. The size of adipocytes of the epididymal fat pad mass in the thalidomide-treated group was smaller than in the control group. The intraperitoneal thalidomide treatment increased triglyceride concentrations by 16% in the red muscle, but not in the white muscle. Conclusion: The results suggested that intraperitoneal thalidomide treatment inhibited abdominal fat accumulation, and that the free fatty acids in the blood were preferentially accumulated in the red muscle rather than in the white muscle.

  • Background: Tumor necrosis factor-alpha and other proinflammatory cytokines are becoming well recognized as key mediators in the pathogenesis of many types of neuropathic pain. Thalidomide has profound immunomodulatory actions in addition to their originally intended pharmacological actions. There has been debate on the analgesic efficacy of opioids in neuropathic pain. The aim of this study was to investigate the effect of thalidomide and morphine on a spinal nerve ligation model in rats. Methods: Male Sprague-Dawley rats weighing 100-120 g were used. Lumbar (L) 5 and 6 spinal nerve ligations were performed to induce neuropathic pain. For assessment of mechanical allodynia, mechanical stimulus using von Frey filament was applied to the paw to measure withdrawal threshold. The effects of intraperitoneal thalidomide (6.25, 12.5, 25 and 50 mg/kg, respectively) and morphine (3 and 10 mg/kg, respectively) were examined on a withdrawal threshold evoked by spinal nerve ligation. Results: After L5 and 6 spinal nerve ligation, paw withdrawal thresholds on the ipsilateral side were significantly decreased compared with pre-operative baseline and with those in the sham-operated group. Intraperitoneal thalidomide and morphine significantly increased the paw withdrawal threshold compared to controls and produced dose-responsiveness. Conclusions: Systemic thalidomide and morphine have antiallodynic effect on neuropathic pain induced by spinal nerve ligation in rat. These results suggest that morphine and thalidomide may be alternative therapeutic approaches for neuropathic pain.

  • Objectives: To evaluate efficacy and toxicity in patients with advanced lung cancer, including non-small cell and small cell variants (NSCLC and SCLC), treated with thalidomide plus chemotherapy. Methods: Fourteen patients with advanced lung cancer were scheduled to receive chemotherapy combined with thalidomide. All patients in this study received thalidomide (100 mg orally per night before sleeping, produced by Changzhou Pharmaceutical Factory Co.Ltd) after the start of chemotherapy for at least 14 days. Chemotherapy was administered according to the condition of patients. After at least 14 days of treatment, efficacy and toxicity were evaluated. Results: There were 6 female and 8 male patients with advanced lung cancer recruited into this study, including 2 with SCLC and 12 with NSCLC. The median age was 56.7 (44-65) years. Progressive disease was observed in 12 patients (12/14), and stable disease in 2 (2/14). Grade 1 to 2 myelosuppression was observed in 4/14 patients, and Grade 1 to 2 elevation of hepatic enzymes was recorded in 5/14 patients. Adverse effects on the gastrointestinal tract were documented in 2/14 patients, all beingGrade 1. No Grade 3-4 toxicity was recorded. No treatment related deaths occurred. Conclusions: Our results demonstrate that thalidomide combined with chemotherapy is mildly effective and safe for treating patients with advanced lung cancer. However, further evaluation of this combination is warranted.

  • Behcet's disease is a chronic relapsing vasculitis characterized by recurrent aphthous oral and genital ulcers with uveitis. Multiple organs can be involved. Entero-Behcet's disease is often uncontrollable, relapsing, and can cause acute intestinal bleeding, fistula formation, or perforation. Corticosteroids, immunosuppressors, and colchicines are used to treat Entero-Behcet's disease with varying degree of success. Thalidomide may also be feasible. We present a 29-year-old male Entero-Behcet's patient suffering from abdominal pain, diarrhea, and back pain. He did not respond to prior treatments, but responded to thalidomide.

  • The aim of this study was to evaluate the relaxant and anti-inflammatory effects of two thalidomide analogs as phosphodiesterase-4 (PDE-4) inhibitors in pregnant rat uterus. Uteri from Wistar female rats were isolated at 19 day of pregnancy. Uterine samples were used in functional studies to evaluate the inhibitory effects of the thalidomide analogs, methyl 3-(4-nitrophthalimido)-3-(3,4- dimethoxyphenyl)-propanoate (4NO2PDPMe) and methyl 3-(4-aminophthalimido)- 3-(3,4-dimethoxyphenyl)-propanoate (4APDPMe), on prostaglandin-$F2{\alpha}$ ($PGF2{\alpha}$)-induced phasic, $K^+$-induced tonic, and $Ca^{2+}$-induced contractions. Accumulation of cAMP was quantified in uterine homogenates by ELISA. Anti-inflammatory effect was assessed by using ELISA for determination of the pro-inflammatory cytokines tumor necrosis factor-${\alpha}$ ($TNF{\alpha}$) and interleukin (IL)-$1{\beta}$, and anti-inflammatory IL-10, from uterine explants stimulated with lipopolysaccharide (LPS). Nifedipine, forskolin and rolipram were used as positive controls where required. Both thalidomide analogs induced a significant inhibition of the uterine contractions induced by the pharmaco- and electro-mechanic stimuli. Nifedipine and forskolin were more potent than the analogs to inhibit the uterine contractility, but these were more potent than rolipram, and 4APDPMe was equieffective to nifedipine. Thalidomide analogs increased uterine cAMP-levels in a concentration-dependent manner. The LPS-induced $TNF{\alpha}$ and $IL-1{\beta}$ uterine secretion was diminished in a concentration-dependent fashion by both analogs, whereas IL-10 secretion was increased significantly. The thalidomide analogs induced utero-relaxant and anti-inflammatory effects, which were associated with the increased cAMP levels as PDE-4 inhibitors in the pregnant rat uterus. Such properties place these thalidomide analogs as potentially safe and effective tocolytic agents in a field that urgently needs improved pharmacological treatments, as in cases of preterm labor.

  • A novel and convenient route for the synthesis of a series of thalidomide derivatives is described. Compound 2 was cyclized with different amines under alkaline condition to obtain 4-nitro substituted phthalimidines 3a-d. Hydroxylactams 4a-d were produced via bromination and hydroxylation. Different acyl chlorides were reacted with hydroxylactams to provide the desired esters 5a-d. All compounds were evaluated by MTT assay for their inhibitory activities against HCT-116, MG-63, MCF-7, HUVEC and HMVEC cell lines in vitro. Most of them showed no obvious cytotoxic effect on normal human cells, compounds 4a-d, $5a_2$, $5a_4$, $5a_5$, $5b_2$, $5c_2$ and $5d_2$ exhibited potent antitumor activities, among which compounds $5a_2$ and $5b_2$ were more effective than 5-FU.

  • Objective: To assess the safety and effectiveness of thalidomide (produced by CHANGZHOU PHARMACEUTICAL FACTORY CO.LTD) combined with chemotherapy in treating patients with advanced colorectal cancer. Method: A consecutive cohort of pretreated patients with advanced colorectal cancer were treated with thalidomide combined with chemotherapy. And chemotherapy for patients with advanced colorectal cancer were administered according to the condition of patients. Thalidomide was orally administered at a dosage of 50mg/day to 150mg/day before sleeping for at least 14 days. After at least 14 days of treatment, safety and side effects were evaluated. Results: There were 12 female and 3 male patients with advanced cancer recruited into this study, including 9 patients with colon, 6 patients with rectal cancer. The median age of patients was 57(41-82) years. Partial response was observed in 2 patients (2/15), and stable disease in 3 patients(3/15). Incidences of Grade 1 to 2 myelosuppression was observed in 1/15 patients, and Grade 1 to 2 elevation of hepatic enzyme was recorded in 1/15 patients. Adverse effects on the gastrointestinal tract were documented in 1/15 patients, and were Grade 1. No Grade 3-4 toxicities were diagnosed. No treatment related death was found. Conclusions: Thalidomide combined with chemotherapy was safe and mildly effective in treating patients with advanced colorectal cancer. However, further study should be conducted to clarify the effectiveness of this combination.

  • Background: The type 2 deviated immunological state is predominant in lepromatous leprosy. Erythema nodosum leprosum (ENL) is an immune-complex mediated reaction that typically occurs in lepromatous leprosy. To date, the serum levels of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-2 receptor, IL-10, IL-$1{\beta}$, IL-1 receptor antagonist and monocyte chemoattractant protein-1 (MCP-1) were reported to be higher in lepromatous leprosy. TNF-${\alpha}$ is also known to be higher in ENL, which is reduced after thalidomide treatment. However the serum type 2 chemokine levels in lepromatous leprosy patients have not been reported. Methods: The serum levels of the type 2 chemokines such as thymus and activation-regulated chemokine (TARC), macrophage-derived chemokine (MDC) and eotaxin together with IL-12 and IL-10 in the sera from leprosy patients were detected using an enzyme-linked solvent assay (ELISA) method. Results: The Serum TARC, MDC, eotaxin, IL-10 and IL-12 levels in lepromatous leprosy patients were not significantly different from the normal control levels. The serum levels were not significantly different between the paucibacillary group and multibacillary group. The serum TARC or MDC levels in the ENL patients were more reduced after a treatment containing thalidomide. Conclusion: The type 2 chemokines are not related to the severity of lepromatous leprosy. The larger reducing effect of the TARC or MDC levels in ENL patients by a treatment containing thalidomide suggests the potential role of these chemokines in the development of ENL and the therapeutic mechanism of thalidomide.
