High Serum Levels of Soluble IL-2 Receptor, Cytokines, and C Reactive Protein Correlate with Impairment of T Cell Response in Patients with Advanced Epithelial Ovarian Cancer

The serum levels of interleukin-(IL-)1α, IL-1β, IL-2, IL-6, TNFα, and sIL-2R and the proliferative response of peripheral blood mononuclear cells (PBMC) to phytohemagglutinin (PHA), anti-CD3 monoclonal antibody (mAb), recombinant IL-2 (rIL-2), and the combination of PHA or anti-CD3 mAb with rIL-2 were studied and correlated with serum levels of C-reactive protein (CRP) in women with advanced epithelial ovarian cancer. The expression of CD25 and CD122 subunities of membrane-bound IL-2R on PHA- or anti-CD3 mAb-stimulated PBMC was also studied. In comparisons with the controls, PBMC response to PHA, anti-CD3 mAb, and rIL-2 was significantly lower in the cancer patients. The addition of exogenous rIL-2 to the PBMC cultures increased response in both controls and patients but did not modify the significance of the differences. After stimulation with PHA or anti-CD3 mAb, the percentage of PBMC CD25⁺or CD122⁺was significantly lower in patients. The serum levels of IL-1α, IL-1β, IL-6, TNFα, sIL-2R, and CRP were significantly increased in patients compared to the controls. Instead, no differences were observed for serum levels of IL-2. A strong association was found between high serum levels of the above-mentioned cytokines, sIL-2R, and CRP. The results of our study on advanced stage (IIIb–IV) ovarian cancer patients are consistent with the previously reported hypothesis that high IL-6 and/or CRP serum levels may represent an important and independent prognostic factor of the likely outcome in cancer patients.     

Phase II study of Temodal in the treatment of patients with advanced nasopharyngeal carcinoma

Purpose: A single-institution phase II trial of Temodal (temozolomide, SCH52365) in Chinese patients with advance nasopharyngeal carcinoma was undertaken to determine the efficacy and safety of the drug in this population. Methods: A total of 14 patients with metastatic or locoregionally recurrent nasopharyngeal carcinoma were entered into the study. One patient was unevaluable. Temodal was given at doses of 150 or 200 mg/m² daily on days 1–5 every 28 days. Results: In all, 30 cycles of Temodal were given with no significant toxicity. All 13 (100%) evaluable patients had progressive disease after 2 (84.6%) or 4 (15.4%) courses. Conclusion: Temodal given on this schedule has no activity in advanced nasopharyngeal carcinoma.

Anti -addiction effects of agmatine against heroin self-administration in rats

Rationale： Drug abuse is serious and costly health problems. Present understanding that drug addiction is a chronic brain disease paves the way for pharmacotherapy. Unfortunately, few medications have proven effective for the treatment of addiction and dependence. Searching novel strategies of pharmacotherapy against drug addiction are challenging. Agmatine （ decarboxylated L - arginine）, an endogenous imidazoline receptor ligand, with multiple pharmacological profiles including its NMDA antagonistic properties, attracts the attention for its potential therapeutic efficacy for drug addiction.     

Acetylcholine Transmission in Nucleus Accumbens and VTA on Heroin- Seeking Elicited by Contextual and Conditioned Cues

The involvement of cholinergic transmission in heroin self - administration and the reinstatement of heroin - seeking was examined in rats trained to nose - poke for intravenous heroin. Systemic treatment with physostigmine modestly reduced the acquisition and rate of heroin self-administration. Following 10 -14 days of self-administration, rats were left in the home environment for 14 days. Withdrawn animals were evaluated for context-induced nosepokes during the first hour after being returned to the self-administration apparatus. One hr later a conditioned stimulus （ house light, light in the nose-poke hole, sound of the infusion pump） was presented to initiate cue-induced reinstatement.     

Monosynaptic and disynaptic projections from the substantia nigra pars reticulata to the parafascicular thalamic nucleus in the rat

We examined a direct pathway and an indirect pathway via the reticular thalamic nucleus (RT) from the substantia nigra pars reticulata (SNr) to the parafascicular thalamic nucleus (PF) by using anterograde and retrograde tract tracing methods. After biotinylated dextranamine (BDA) injection into the dorsolateral part of the SNr, many labeled fibers and axon terminals were distributed in the ventral part of the RT, as well as in the ventrolateral part of the PF, bilaterally with an ipsilateral dominance. After BDA injection into the ventral part of the RT, a plexus of labeled axons was found bilaterally with an ipsilateral dominance in the ventrolateral part of the PF. After combined injections of BDA into the dorsolateral part of the SNr and cholera toxin B subunit (CTb) into the ventrolateral part of the PF on the same side, overlapping distribution of BDA-labeled fibers and CTb-labeled neurons was observed in the ventral part of the RT ipsilateral to the injection sites, where the BDA-labeled axon terminals made symmetrical synaptic contacts with soma and dendrites of the CTb-labeled neurons.
