Several experiments have demonstrated that there is a relationship between neuroendocrine and immune systems. Despite these interesting findings, only few studies have been performed up to now to evaluate the possible importance of neuroimmune interactions in influencing the biological efficacy and toxicity of cancer immunotherapy with IL-2. To analyze the(More)
Eleven dogs with canine transmissible venereal tumour (CTVT) were given vincristine sulphate chemotherapy to induce tumour regression. Biopsy specimens were collected from tumours during the growth phase, before chemotherapy, and again from the same dogs during the regression induced by chemotherapy. Laboratory assessment included cytology, histology, the(More)
The aim of the study was to determine the properties of a standardized extract of ginseng root in inducing a higher immune response in vaccination against influenza. Attention was also paid to the common cold in this multicentre, two-arm, randomized, placebo-controlled, double-blind investigation. A total of 227 volunteers who visited 3 private practices in(More)
The pineal hormone melatonin (MLT) is able to exert an oncostatic action. Its possible use in the treatment of human tumors, however, has not yet been investigated. The present study was carried out to evaluate the effects of MLT in patients with metastatic solid tumors resistant to conventional therapies. The study included 54 patients, most of them were(More)
It is known that the pineal gland has some antitumor activity. Melatonin, its most important hormone, has been shown to inhibit tumor growth in vivo and in vitro. Moreover, some investigations have demonstrated an altered melatonin secretion in cancer patients. Despite these interesting data, clinical trials have never been carried out to evaluate the(More)
Clinical studies have demonstrated an altered pineal function in cancer patients. Owing to the documented antineoplastic activity of the pineal gland, these anomalies could have a prognostic significance. This study was carried out to monitor changes in blood levels of melatonin, the most important pineal hormone, in relation to the clinical response to(More)
In this paper we extend the basic principles and results of conservative logic to include the main features of many-valued logics with a finite number of truth values. Different approaches to many-valued logics are examined in order to determine some possible functionally complete sets of logic connectives. As a result, we describe some possible(More)
The pineal hormone melatonin (MLT) has been shown to influence many biological functions, including immune response, cancer growth and brain neurotransmitter contents. On the basis of its biological properties, a study was started to evaluate the influence of MLT on IL-2 immunotherapy toxicity. The study was carried out in metastatic renal cancer patients.(More)
