Abstract
BACKGROUND Assumptions about the damaging effects of radiotherapy (XRT) are based on studies in which total dose, dose fraction, treatment volume, degree of malignancy, chemotherapy, tumor recurrence, and neurologic comorbidity interact with XRT effects. This is a prospective, long-term study of XRT effects in adults, in which total dose and dose fraction were constrained and data related to tumor recurrence and neurologic comorbidity (e.g., hypertension) were excluded. METHODS The effects of XRT on the cognitive and radiographic outcomes of 26 patients with low-grade, supratentorial, brain tumors yearly from baseline (6 weeks after surgery and immediately before XRT) and yearly to 6 years were examined. Radiographic findings were examined regionally. RESULTS Selective cognitive declines (in visual memory) emerged only at 5 years, whereas ratings of clinical MRI (T2 images) showed mild accumulation of hyperintensities with post-treatment onset from 6 months to 3 years, with no further progression. White matter atrophy and total hyperintensities demonstrated this effect, with subcortical and deep white matter, corpus callosum, cerebellar structures, and pons accounting for these changes over time. About half of the patients demonstrated cognitive decline and treatment-related hyperintensities. CONCLUSIONS There was no evidence of a general cognitive decline or progression of white matter changes after 3 years. Results argue for limited damage from XRT at this frequently used dose and volume in the absence of other clinical risk factors.

Abstract
BACKGROUND The functional derangements in the myocyte cell membrane, the sarcolemma, during short myocardial ischaemia and reperfusion are attributed to excessive influx of Ca2+ ions via the voltage-sensitive calcium channels (VSCC) and to the free radical-related injury. However, it is unclear whether the primary changes in the VSCC should be attributed to the ischaemic effect or to free radical action on channel constituents. Under these circumstances of ischaemia and reperfusion, volatile anaesthetics have exhibited protective properties on the myocardium. The present study is aimed at characterizing the effect of artificially-generated oxygen free radicals on the VSCC in canine sarcolemma, independently of the effect of ischaemia, and the effect of halothane on the membranes during the surge of the free radicals. METHODS Selective production of free radicals (O2-, CO2-) was made by gamma irradiation of isolated sarcolemma membranes with 137 Cesium (Cs), in the presence of 20 mM sodium formate. Control studies were performed without formate in the aqueous solution. In an additional group, liquid halothane (3 microl. 1.9 vol%) was added to the sarcolemma / formate preparation immediately prior to irradiation. The effects of free radicals on the VSCC was evaluated by redioligand binding studies of the calcium channel blocker [3H] isradipine to the sarcolemma. RESULTS In six control studies, the rediolytic aqueous species produced by 137 Cs irradiation resulted in unchanged [3 H] isradipine binding. In the presence of formate [n=9], the free radicals have caused a 23% to 25% decrease, both, in density and dissociation constant (P=0.05) of [3 H]isradipine to the VSCC binding sites. When superoxide radicals were generated in the presence of 1.9% halothane and formate (n=6), a significant increase in maximal binding capacity (by 55% +/- 2; P<0.01) and in the dissociation constant (by 209% +/- 35, P<0.01) occurred. CONCLUSION Oxidative free radicals which are generated by gamma irradiation exerted minimal changes on the normal function of the VSCC as reflected by the non-significant changes in [3 H] isradipine specific binding. Introduction of halothane into free radical generating system causes acute perturbations to the VSCC kinetics, and does not provide protection to the cardiac membranes.

Abstract
One hundred and forty-six patients with acute leukaemia (81 with ANLL and 65 with ALL) received allogeneic bone marrow transplantation from their fully matched siblings. 121 patients underwent T-cell depletion (TCD) using Campath 1 monoclonal rat anti-human lymphocyte (CDw52) antibodies; 67 with Campath 1M and 54 with Campath 1G isotypes. Patients were conditioned for transplant using either total body irradiation combined with chemotherapy (125 patients) or busulfan and cyclophosphamide (21 patients). 112 recipients of T-cell depleted allografts received in addition total lymphoid irradiation (TLI) for prevention of rejection. Engraftment of neutrophils (> 0.5 x 10(9)/l) and platelets (> 25 x 10(9)/l) occurred on days 15 and 18, and on days 18 and 20 in recipients of Campath 1M and Campath 1G treated marrows respectively. Rejection was documented in 6.8% of T-cell depleted transplants. Leukaemia relapse-free survival at 2 years was 83% for patients transplanted in first CR, 76% in second CR (P2 = 0.34) and 42% in advanced leukaemia (P2 = 0.009). 81 marrow recipients, 38 with Campath 1M and 43 with Campath 1G treated marrow, received post-transplant graded increments of donor's peripheral blood lymphocytes (PBL) to induce graft-versus-leukaemia (GVL) effects. Administration of donor's PBL was associated with clinically significant GVHD and with decreased relapse rate especially in patients with ALL. Our data suggest that in patients receiving marrow allografts depleted of T cells by Campath 1 monoclonal antibodies, rejection can be reduced by adequate pregrafting immunosuppression. In patients with advanced disease, post-transplant cell-mediated immunotherapy (CMI) using donor's PBL may be beneficial; however, further studies are needed to define the optimal schedule of CMI for safe and effective prevention of relapse following TCD bone marrow transplantation in malignant haematological diseases.

Abstract
BACKGROUND The management of pleural neoplasms, specifically mesothelioma, remains difficult. We performed a phase I trial in 54 patients with isolated hemithorax pleural malignancy to determine (a) the feasibility of intraoperative, intrapleural photodynamic therapy after debulking surgery; (b) the influence of light dose/sensitizer interval on postoperative morbidity in order to define the photodynamic therapy (PDT) maximal tolerated dose (MTD); and (c) whether first order dosimetry could be applied to this complex geometry. METHODS Cohorts of three patients were given escalating intraoperative light doses of 15-35 J/cm2 48 h after i.v. delivery of 2.0 mg/kg Photofrin II (Quadra Logic Technologies, Vancouver, British Columbia, Canada), and then escalating light doses of 30-32.5 J/cm2 after a 24-h sensitizer/operation interval. Twelve patients could not be debulked to the prerequisite 5 mm residual tumor thickness. The remaining 42 patients underwent 19 modified pleuropneumonectomies, five lobectomy-pleurectomies, and 18 pleurectomies. Intrapleural PDT was delivered using 630 nm light from two argon pump-dye lasers, and real-time and cumulative light doses were monitored using seven uniquely designed, computer-interfaced photodiodes. RESULTS There was one 30-day mortality from intraoperative hemorrhage. In the 48-h sensitizer/operation group (n = 33), possible PDT-related complications included an empyema with late hemorrhage in one of three patients at 17.5 J/cm2 and a bronchopleural fistula at 35 J/cm2. At each of these light doses, three additional patients were treated without complication. Two patients subjected to 24-h sensitizer dosing and 32.5 J/cm2 developed esophageal perforations after pleuropneumonectomy at identical sites. The MTD was declared as 30 J/cm2 light with a 24-h dosing interval when none of the six patients (three original, three repeat) at that level developed toxicity. CONCLUSIONS These data demonstrate that resection and intrapleural PDT can be performed safely with currently available sensitizers and lasers. Phase II and III trials are now warranted at this MTD in a homogeneous population of patients with pleural malignancies.

Abstract
PURPOSE Phase I study designed to determine the maximum tolerated dose of intraoperative photodynamic therapy (PDT) at laparotomy/debulking surgery in patients with refractory or recurrent, disseminated intraperitoneal tumors. METHODS AND MATERIALS Patients received dihematoporphyrin ethers (DHE) 1.5-2.5 mg/kg by i.v. injection prior to surgery. Patients resected to < or = 5 mm of residual disease underwent laser light delivery to all peritoneal surfaces. RESULTS Fifty-four patients entered the study. Thirty-nine underwent resection and light delivery/PDT. PDT dose was escalated by increasing DHE from 1.5 to 2.5 mg/kg, shortening the interval between DHE injection and surgery from 72 to 48 hr, and increasing the light dose. Initially, 630 nm red light alone was used. In this group, PDT of 2.8-3.0 J/cm2 induced small bowel edema and resulted in 3 small bowel perforations after bowel resection or enterotomy. Further light dose escalation, however, was achieved by switching to less penetrating 514 nm green light to the bowel/mesentery. In later patients, whole peritoneal PDT was supplemented with boost doses of 10-15 J/cm2 red light or 5-7.5 J/cm2 green light to high risk areas. Small bowel complications were not seen after switching to less penetrating green light. Dose limiting toxicities occurred in 2 of 3 patients at the highest light dose of 5.0 J/cm2 green light with boost. These patients had pleural effusions that required thoracentesis and postoperative respiratory support for 7-9 days, while one had a gastric perforation. At potential follow-up times of 3.8-43.1 months (median 22.1 months), 30/39 patients are alive and 9/39 are free of disease. CONCLUSION The maximum tolerated dose of intraoperative PDT following debulking surgery performed 48 hr after intravenous administration 2.5 mg/kg DHE is 3.75 J/cm2 of 514 nm green light to the entire peritoneal surface with boosts to 5.0-7.5 J/cm2 of 514 nm green light or 10-15 J/cm2 of 630 nm red light to sites of gross disease encountered at surgery.

Abstract
The power spectrum of instantaneous heart rate fluctuations was used to determine the optimal doses of atropine that induce a maximal vagolytic or vagomimetic effect. In a crossover placebo controlled study, eight volunteers received increasing bolus doses of intravenous atropine (0.1 to 2.3 mg per subject) or placebo, and frequency bands of the power spectrum were integrated. During atropine administration a significant bimodal dose dependence was observed for the respiratory peak (0.2 to 0.4 Hz, p = 0.0006), the midfrequency band (0.09 to 0.15 Hz, p = 0.0035), and mean heart rate (p < 0.0001). Low doses (< 0.4 mg per subject) increased the respiratory and midfrequency band power, with maximal response at 0.2 mg per subject. Larger doses of atropine, 0.5 to 2.3 mg per subject, markedly reduced the power in all frequency bands in a dose-dependent way. The corresponding changes in mean heart rate were simultaneous, but in the opposite direction. We suggest that the respiratory peak of the power spectrum can be used to optimize drug effects on cardiac parasympathetic control.

Abstract
1. The value of low dosage of pyridostigmine (30 mg three times daily) in preventing peripheral anti-muscarinic side effects of a transdermal controlled-release formulation of hyoscine, was tested in a double-blind placebo-controlled study, involving 47 healthy subjects. 2. Salivary excretion was repeatedly measured during 48 h of combined therapy of two transdermal hyoscine patches with pyridostigmine and 14 h after its cessation. Blood acetylcholinesterase activity was also measured, serving as an index of pyridostigmine bioavailability. 3. The adjunctive therapy with pyridostigmine was highly effective in preventing the substantial impairment in salivary flow caused by the transdermal formulation. An associated 23% inhibition of blood acetylcholinesterase activity was observed. 4. Small doses of pyridostigmine may therefore have a role in increasing the tolerability of transdermal hyoscine therapy. In some patients this drug combination might also allow some increment of the hyoscine dose.

Abstract
Nitroxide compounds are stable free radicals which were previously investigated as hypoxic cell radiosensitizers. The stable nitroxide 4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl (Tempol) has recently been shown to protect aerated cells in culture against superoxide generated from hypoxanthine/xanthine oxidase, hydrogen peroxide, and radiation-induced cytotoxicity and to modestly sensitive hypoxic cultured cells. To extend these observations from the cellular level to the whole animal, the toxicity, pharmacology, and in vivo radioprotective effects of Tempol were studied in C3H mice. The maximum tolerated dose of Tempol administered i.p. was found to be 275 mg/kg, which resulted in maximal Tempol levels in whole blood 5-10 min after injection. Mice were exposed to whole-body radiation in the absence or presence of injected Tempol (275 mg/kg) 5-10 min after administration. Tempol treatment provided significant radioprotection (P less than 0.0001); the dose of radiation at which 50% of Tempol-treated mice die at 30 days was 9.97 Gy, versus 7.84 Gy for control mice. Tempol represents a new class of in vivo, non-sulfur-containing radiation protectors. Given the potential for hypoxic radiosensitization and aerobic cell radioprotection, Temporal or other analogues may have potential therapeutic application.

Abstract
An animal model of pulmonary radiation-induced lung injury was established in the hamster and the effects of pretreatment with recombinant human CuZn superoxide dismutase (SOD) on the development of the lesion were evaluated. Hamsters exposed to a single irradiation dose of 2000 cGy delivered to the thorax were treated with 150 mg/kg body weight of SOD or an equivalent volume of saline intraperitoneally 75 min and subcutaneously 5 min before receiving irradiation. At 4, 8, and 16 weeks following irradiation, pulmonary injury was evaluated by the grading of morphologic changes semiquantitatively, measurement of lung hydroxyproline content, and analysis of bronchoalveolar lavage fluid for total and differential cell counts and total protein concentration. Radiation-induced lung injury in saline-pretreated animals was documented at 16 weeks by histologic morphology and increased protein in bronchoalveolar lavage fluid. SOD protected against radiation-induced pulmonary injury as indicated by the absence of severe histopathologic changes and prevention of elevation in bronchoalveolar lavage protein levels. The beneficial effects of SOD in preventing radiation-induced pulmonary toxicity suggests that this recombinant enzyme may play a role in protection against radiation-induced pulmonary injury in humans.

Abstract
The interaction between a low-dose cholinesterase inhibitor, pyridostigmine (PYR), and atropine was investigated by spectral analysis of heart rate fluctuations in eight healthy humans. Each subject was given increasing boluses of IV atropine during treatment with PYR (30 mg.3/day) or placebo. PYR attenuated the bimodal dose-dependent changes in the respiratory peak (which respresents the parasympathetic control) in response to atropine. We suggest that spectral analysis can be used for quantifying the complex dose-dependent cholinergic agonist-antagonist interactions, and may help to disclose an asymptomatic low-dose intoxication with acetylcholinesterase inhibitors.

Abstract
The autonomic cardiac control was studied as a sensitive parameter of anticholinergic treatment in humans, using heart-rate (HR) power spectrum. A cross-over placebo controlled study was performed in 8 young volunteers who received increasing bolusdoses of IV atropine (from 1.3 micrograms/kg to 29.9 micrograms/kg) or placebo. Computing the HR power spectrum and integrating over specific frequency bands, we focused in particular on the respiratory frequency band (usually between 0.2-0.4 Hz) which is purely of vagal mediation. At small atropine doses (less than 5.2 micrograms/kg), the respiratory peak increased, relative to baseline, with maximal response at 2.6 micrograms/kg (from 1.0 to 1.9 +/- 0.9). Larger doses of atropine (greater than or equal to 6.5 micrograms/kg) reduced the power of the respiratory peak, by a few orders of magnitude, in a dose-dependent way. Corresponding changes were observed in mean HR but in the opposite direction i.e., a maximal bradycardia at 2.6 micrograms/kg and a nearly two fold increase in mean HR at 29.9 micrograms/kg. We conclude that atropine has a bimodal dose-dependent effect on parasympathetic cardiac control. Since the use of HR spectral analysis has been demonstrated in various animal species, we suggest that it can be used as a sensitive noninvasive probe for animal to man transformation studies.

Abstract
Patients with disseminated intraperitoneal malignant neoplasms were given intra-abdominal photodynamic therapy. Patients received dihematoporphyrin ethers intravenously 48 to 72 hours before laparotomy at doses of 1.5 to 3.0 mg/kg. At operation, as much tumor as possible was resected. Red light (630 nm) was delivered to all peritoneal surfaces from an argon-pumped dye laser at doses ranging from 0.2 to 3.0 J/cm2 in an escalating fashion. Viscera and peritoneal surfaces were anatomically isolated and exposed to light for intervals calculated to deliver the prescribed energy. Light was delivered to mesentery and bowel by a flat-cut optical fiber, while other areas, including diaphragm, viscera, omental bursa, gutters, and pelvis, were delivered light through a diffusing wand. Twenty-three patients (13 with ovarian cancer, eight with sarcoma, and two with pseudomyxoma peritoneii) underwent photodynamic therapy. Five of eight patients cleared positive peritoneal cytologies after treatment. Six patients remained clinically free of disease for up to 18 months, and five patients had treatment-related complications. Intraperitoneal phototherapy is technically feasible and deserving of clinical evaluation.

Abstract
For a decade, the authors have experimented with treatment for unresectable adult soft tissue and bony sarcomas. Over the last 6 years, they have combined hyperfractionated radiation therapy and intravenous iododeoxyuridine as a radiosensitizer, in regimens designed to minimize toxicity and permit delivery of aggressive radiation therapy. Patients with solitary lesions and those with metastasis (38%) were treated in the hope of both potential cure in some and durable palliation in others. The most formidable of these cancers have been those that are large or massive, often requiring five or more fields and extensive treatment planning. The authors report results from 36 patients with large unresectable sarcomas (tumors ranging from 5 to 35 cm; average 14 cm) treated with hyperfractionated radiation therapy, with a minimum follow-up of 1 year, follow-up of 4 or more years (in 50%), or follow-up until death. Overall local control has been 60%, with control of 66% of lesions from 5 to 9 cm, 63% of those from 10 to 14 cm, 63% of those from 15 to 19 cm, and 57% of those greater than 20 to 40 cm. Morbidity has been modest. This experience compares favorably with the authors' earlier trials with misonidazole, and toxicity has been reduced considerably.

Abstract
A toxicity study was performed in a canine model to explore the feasibility of using intraperitoneal photodynamic therapy for patients with peritoneal carcinomatosis. Dogs received 1.25 mg/kg Photofrin II both intravenously (48 hours) and intraperitoneally (2 hours) before intraperitoneal light treatment. The entire peritoneal surface was illuminated with 0.57-0.74 J/cm2 of red light (630 nm). Thirteen dogs were treated: 4 control and 9 full treatment. Of the fully treated dogs, 5 received a single treatment and 4 received 3 treatments. The dogs were evaluated clinically and pathologically for immediate (4 days) and late (60 days) side effects. All animals tolerated the treatment without significant morbidity. Postoperative blood tests were normal except for low lymphocyte counts and elevated liver transaminases, both of which normalized rapidly. Histopathologically, there was approximately a 50% incidence of mild inflammatory peritoneal response. This study provides the basis for a Phase I human trial.

Abstract
In many pathological situations, tissue damage is caused by cellular generation of superoxide free radicals (O2-). These active species are generated during post-ischemic reperfusion of organs, in hyperoxic tissue, during acute and chronic inflammation and during exposure to ionizing radiation. Exogenous superoxide dismutase (SOD) was shown to significantly prevent such damage. The genes for human cytosolic Cu/ZnSOD and mitochondrial MnSOD were cloned and introduced into an E. coli expression system. The proteins were expressed in high yields and purified to homogeneity, yielding pharmaceutical-grade materials. These enzymes were used in a variety of in vivo animal models for the demonstration of their protective effects against oxidative damage. Comparative pharmacokinetic studies in rats have revealed that the half-life of Cu/ZnSOD was 6-10 min., while that of MnSOD was 5-6 hours, thus indicating that MnSOD may be superior to Cu/ZnSOD for the treatment of chronic diseases. Indeed, MnSOD was found to be effective as an anti-inflammatory agent in the rat carrageenan induced paw edema acute inflammation model. Both enzymes were also effective in ameliorating post-irradiation damage in mice exposed to whole-body or localized chest X-ray radiation.
