Abstract
PURPOSE Biallelic loss-of-function variants in ST3GAL5 cause GM3 synthase deficiency (GM3SD) responsible for Amish infantile epilepsy syndrome. All Amish patients carry the homozygous p.(Arg288Ter) variant arising from a founder effect. To date only 10 patients from 4 non-Amish families have been reported. Thus, the phenotypical spectrum of GM3SD due to other variants and other genetic backgrounds is still poorly known. METHODS We collected clinical and molecular data from 16 non-Amish patients with pathogenic ST3GAL5 variants resulting in GM3SD. RESULTS We identified 12 families originating from Reunion Island, Ivory Coast, Italy, and Algeria and carrying 6 ST3GAL5 variants, 5 of which were novel. Genealogical investigations and/or haplotype analyses showed that 3 of these variants were founder alleles. Glycosphingolipids quantification in patients' plasma confirmed the pathogenicity of 4 novel variants. All patients (N = 16), aged 2 to 12 years, had severe to profound intellectual disability, 14 of 16 had a hyperkinetic movement disorder, 11 of 16 had epilepsy and 9 of 16 had microcephaly. Other main features were progressive skin pigmentation anomalies, optic atrophy or pale papillae, and hearing loss. CONCLUSION The phenotype of non-Amish patients with GM3SD is similar to the Amish infantile epilepsy syndrome, which suggests that GM3SD is associated with a narrow and severe clinical spectrum.

Abstract
AIMS LMNA-linked familial partial lipodystrophy type 2 (FPLD2) leads to insulin resistance-associated metabolic complications and cardiovascular diseases. We aimed to characterise the disease phenotype in a cohort of patients carrying an LMNA founder variant. METHODS We collected clinical and biological data from patients carrying the monoallelic or biallelic LMNA p.(Thr655Asnfs*49) variant (n = 65 and 13, respectively) and 19 non-affected relative controls followed-up in Reunion Island Lipodystrophy Competence Centre, France. RESULTS Two-thirds of patients with FPLD2 (n = 51) and one-third of controls (n = 6) displayed lipodystrophy and/or lean or android morphotype (P = 0.02). Although age and BMI were not statistically different between the two groups, the insulin resistance index (median HOMA-IR: 3.7 vs 1.5, P = 0.001), and the prevalence of diabetes, dyslipidaemia, and non-alcoholic fatty liver disease were much higher in patients with FPLD2 (51.3 vs 15.8%, 83.3 vs 42.1%, and 83.1 vs 33.3% (all P ≤ 0.01), respectively). Atherosclerosis tended to be more frequent in patients with FPLD2 (P = 0.07). Compared to heterozygous, homozygous patients displayed more severe lipoatrophy and metabolic alterations (lower BMI, fat mass, leptin and adiponectin, and higher triglycerides P ≤ 0.03) and tended to develop diabetes more frequently, and earlier (P = 0.09). Dilated cardiomyopathy and/or rhythm/conduction disturbances were the hallmark of the disease in homozygous patients, leading to death in four cases. CONCLUSIONS The level of expression of the LMNA 'Reunionese' variant determines the severity of both lipoatrophy and metabolic complications. It also modulates the cardiac phenotype, from atherosclerosis to severe cardiomyopathy, highlighting the need for careful cardiac follow-up in affected patients.

Abstract
Reunion Island is a French oversea department in the Indian Ocean with 1.6/1000, an estimated prevalence of deafness that is almost double as compared to the mainland France. Twelve children having isolated bilateral prelingual profound deafness along with motor delay attributed to vestibular areflexia were enrolled. Their mean walking age was 19 months. Electroretinography and temporal bone CT-scans were normal in all cases. A novel homozygous frameshift lipoma HMGIC fusion partner-like 5 (LHFPL5) variant c.185delT p.(Phe62Serfs*23) was identified using whole-exome sequencing. It was found in seven families. Four patients from two different families from both Reunion Island and mainland France, were compound heterozygous: c.185delT p.(Phe62Serfs*23) and c.472C > T p.(Arg158Trp). The phenotype observed in our patients completely mimics the hurry-scurry (hscy) murine Tmhs knock-out model. The recurrent occurrence of same LHFPL5 variant in Reunion Island is attributed to common ancestor couple born in 1693.

Abstract
Background Pulmonary alveolar proteinosis (PAP) is very rare in children. Only a few small series have been published, with little information about long-term progression. The objective of our study was to describe the clinical, radiological and pathological features, and the long-term course of PAP in a cohort of 34 children from La Réunion Island. Methods Data were retrospectively collected from medical files. Radiological and pathological elements were reviewed by two pediatric radiologists and three pathologists, respectively. Results Thirteen cases were familial and 32/34 (94%) cases were family connected. Disease onset occurred in the first six months of life in 82% of the patients. Thoracic computed tomography scans showed the typical “crazy-paving” pattern in 94% of cases. Respiratory disease was associated with a liver disorder, with the detection of liver enlargement at diagnosis in 56% of cases. The course of the disease was characterized by frequent progression to chronic respiratory insufficiency, accompanied by the appearance of cholesterol granulomas and pulmonary fibrosis. Overall prognosis was poor, with a mortality of 59% and an overall five-year survival rate from birth of 64%. Whole-lung lavages were performed in 21 patients, with no significant effect on survival. Liver disease progressed to cirrhosis in 18% of children, with no severe complication. Conclusions PAP in children from la Réunion Island is characterized by an early onset, associated liver involvement, poor prognosis and frequent progression to lung fibrosis, despite whole-lung lavages treatment. The geographic clustering of patients and the detection of many familial links between most of the cases strongly suggest a genetic etiology, with an autosomal recessive mode of inheritance.

Abstract
CONTEXT Mutations in LMNA, encoding A-type lamins, lead to multiple laminopathies, including lipodystrophies, progeroid syndromes, and cardiomyopathies. Alterations in the prelamin-A posttranslational maturation, resulting in accumulation of farnesylated isoforms, cause human progeroid syndromes. Accumulation of mutant nonfarnesylated prelamin-A leads to cardiomyopathy or progeria in mice, but no data have been provided in humans. OBJECTIVE, DESIGN, SETTING, AND PATIENTS: We searched for LMNA mutations in seven women originating from Reunion Island who were referred for a severe lipodystrophic syndrome. Clinical, molecular, genealogical, and cellular studies were performed in probands and relatives. RESULTS The seven probands showed a severe partial lipodystrophic syndrome with diabetes and/or acanthosis nigricans, liver steatosis, hypertriglyceridemia, and low serum leptin and adiponectin levels. Three probands also had severe cardiac rhythm and conduction disturbances. We identified in all probands a homozygous LMNA p.T655fsX49 mutation leading to expression of a mutated prelamin-A with 48 aberrant C-terminal amino acids, preventing its physiological posttranslational farnesylation and maturation. Genealogical and haplotype analyses were consistent with a founder mutation transmitted from a common ancestor in the 17th century. In probands' cultured fibroblasts, mutated prelamin-A was associated with typical laminopathic nuclear dysmorphies, increased oxidative stress, and premature senescence. Heterozygous relatives were asymptomatic or partially affected, in favor of a codominant transmission of the disease with incomplete penetrance in heterozygotes. CONCLUSIONS We reveal that a homozygous mutation of prelamin-A preventing its farnesylation leads to a severe lipodystrophic laminopathy in humans, which can be associated with cardiac conduction disturbances, stressing the pathogenicity of nonfarnesylated prelamin-A in human laminopathies.

Abstract
Beriberi is an uncommon disorder related to thiamine deficiency. It is mainly found in underdeveloped countries among populations with poorly diversified diet, consisting largely of milled white cereals, a poor source of thiamine. In industrialized countries, thiamine deficiency with cardiac failure is more frequently found than the dry beriberi in high risk groups like chronic alcoholics. Nevertheless our attention was drawn to an outbreak of 70 cases of dry beriberi which occurred from 1997 to 2005 in the French territories of Reunion and Mayotte islands. It was characterized by an acute or sub-acute sensorimotor polyneuropathy with axonal lesions, affecting the lower limbs and occasionally the upper limbs, sometimes associated with cardiac beriberi. It affected young, non alcoholic individuals from the Mahoran and Comorian community who were in apparent good health when the illness occurred. Our study highlighted the feeding habits which are partly responsible for the development of the disease due to a chronic lack of thiamine and which probably contributed together with multiple cofactors to trigger off the illness. But many elements and mainly biological ones, also lead us to think that there is a genetic predisposition to develop this neuropathy.

Abstract
OBJECTIVE Breech delivery is known to increase maternal and fetal morbidity. Several methods have been suggested to increase the rate of fetal reverse. The aim of this study was to assess the efficacity of acupuncture or more exactly moxibustion at the 34th AW to increase the rate of fetal reverse. MATERIALS AND METHODS Clinical trial over 68 major pregnant women, adjusted on parity, whose fetus was in breech presentation at the 8th month. They were randomised to receive or not the treatment. It is the first randomised clinical trial performed on this subject in France, from January 1st 2006 to April 30th 2008. RESULTS The rate of fetal reverse is not statistically higher with moxibustion for the primipara (7/19 versus 6/19) and for the multipara (9/14 versus 11/19). CONCLUSION Moxibustion, such as performed in this trial, has not modified the fetal rate reverse either on primipara or on multipara.

Abstract
BACKGROUND Although cannabis has been used as a medicine for several centuries, the therapeutic properties of cannabis preparations (essentially haschich and marijuana) make them far most popular as a recreational drugs. STATE OF THE ART Scientific studies on the effects of cannabis were advanced considerably by the identification in 1964 of cannabinoid D9-tetrahydrocannadinol (THC), recognized as the major active constituent of cannabis. Cloning of the centrally located CB1 receptor in 1990 and the identification of the first endogenous ligand of the CB1 receptor, anandamide, in 1992 further advanced our knowledge. PERSPECTIVE AND CONCLUSIONS Progress has incited further research on the biochemistry and pharmacology of the cannabinoids in numerous diseases of the central nervous system. In the laboratory animal, cannabinoids have demonstrated potential in motion disorders, demyelinizing disease, epilepsy, and as anti-tumor and neuroprotector agents. Several clinical studies are currently in progress, but therapeutic use of cannabinoids in humans couls be hindered by undesirable effects, particularly psychotropic effects. CB1 receptor antagonists also have interesting therapeutic potential.

Abstract
PURPOSE Unverricht-Lundborg disease (ULD) is the most frequent form of progressive myoclonus epilepsy. ULD is caused mostly by a homozygous expansion of a dodecamer repeat in the cystatin B gene (CSTB) promoter. We present here a clinical and molecular study of 14 ULD patients originating from Reunion Island, a French island in the Indian Ocean. METHODS These ULD patients were clinically evaluated, and the diagnosis of ULD was confirmed molecularly. We analyzed 12 microsatellites flanking CSTB and estimated the date of introduction of the ULD mutation on Reunion Island. RESULTS These cases were clinically very similar, with the typical myoclonus syndrome associated with generalized tonic-clonic seizures, cerebellar involvement and, in some cases, mild mental deterioration. The mean age at onset was 9.6 years (range, 5-14 years), and the mean disease duration was 27 years (range, 5-47 years). The 14 patients harbored the typical ULD mutation, with variable degrees of expansion (mean of 56.3 repeats; range, 49-63). A founder effect was detected, with all but one of the Reunion ULD chromosomes displaying expansions belonging to the same haplotype, 1-1-1-2-6-4-3. We estimated the date of arrival of the most recent common ancestor (MRCA) of these patients on Reunion Island to the middle of the eighteenth century. CONCLUSIONS These Reunion ULD patients displayed a homogeneous phenotype. Our molecular results are compatible with the instability of the repeat expansion and revealed a founder effect in Reunion ULD patients and the existence of a MRCA about 12 generations ago.

Abstract
Unverricht-Lundborg disease (ULD) is a progressive myoclonus epilepsy common in Finland and North Africa, and less common in Western Europe. ULD is mostly caused by expansion of a dodecamer repeat in the cystatin B gene ( CSTB) promoter. We performed a haplotype study of ULD chromosomes (ULDc) with the repeat expansion. We included 48 West European Caucasian (WEC) and 47 North African (NA) ULDc. We analysed eight markers flanking CSTB(GT10-D21S1890-D21S1885-D21S2040-D21S1259- CSTB-D21S1912-PFKL-D21S171) and one intragenic variant in the CSTB 3' UTR (A2575G). We observed a founder effect in most of the NA ULD patients, as 61.7% of the NA ULDc (29/47) shared the same haplotype, A1 (1-1-A-1-6-7), for markers D21S1885-D21S2040-A2575G-D21S1259-D21S1912-PFKL. Moreover, if we considered only the markers D21S1885, D21S2040, A2575G and D21S1259, 43 of the 47 NA ULDc shared the same alleles 1-1-A-1, haplotype A. As previously shown, the WEC ULDc were heterogeneous. However, the Baltic haplotype, A3 (5-1-1-A-1-1), was observed in ten WEC ULDc (20.8%) and the CSTB 3'UTR variant, which we called the Alps variant, was observed in 17 ULDc (35.4%). Finally, as almost all NA patients, like Scandinavian patients, were of the haplotype A, we assumed that there was an ancient common founder effect in NA and Baltic ULD patients. We estimated that the putative most recent common ancestral ULD carrier with this haplotype A must have existed about 2,500 years ago (100-150 generations). Finally, this work provides evidence for the existence of only a small number of founder mutations in ULD.

Abstract
BACKGROUND Familial hemiplegic migraine, an autosomal dominant disorder characterized by attacks of transient hemiparesis followed by a migraine headache, is classically divided into pure familial hemiplegic migraine (affecting 80 percent of families) and familial hemiplegic migraine with permanent cerebellar signs (affecting 20 percent of families). Mutations in CACNA1A, which encodes a neuronal calcium channel, are present in 50 percent of families with hemiplegic migraine, including all those with cerebellar signs. We studied the various clinical manifestations associated with mutations in CACNA1A in families with hemiplegic migraine with and without cerebellar signs. METHODS CACNA1A was analyzed and nine mutations were detected in 15 of 16 probands of families affected by hemiplegic migraine and cerebellar signs, in 2 of 3 subjects with sporadic hemiplegic migraine and cerebellar signs, and in 4 of 12 probands of families affected by pure hemiplegic migraine. Genotyping of probands and relatives identified a total of 117 subjects with mutations whose clinical manifestations were assessed in detail. RESULTS Eighty-nine percent of the subjects with mutations had attacks of hemiplegic migraine. One third had severe attacks with coma, prolonged hemiplegia, or both, with full recovery. All nine mutations, including five newly identified ones, were missense mutations. Six mutations were associated with hemiplegic migraine and cerebellar signs, and 83 percent of the subjects with these six mutations had nystagmus, ataxia, or both. Three mutations were associated with pure hemiplegic migraine. CONCLUSIONS Hemiplegic migraine in subjects with mutations in CACNA1A has a broad clinical spectrum. This clinical variability is partially associated with the various types of mutations.

Abstract
Familial hemiplegic migraine (HM) is an autosomal dominant migraine with aura. In 20% of HM families, HM is associated with a mild permanent cerebellar ataxia (PCA). The CACNA1A gene encoding the alpha1A subunit of P/Q-type voltage-gated calcium channels is involved in 50% of unselected HM families and in all families with HM/PCA. Four CACNA1A missense mutations have been identified in HM: two in pure HM and two in HM/PCA. Different CACNA1A mutations have been identified in other autosomal dominant conditions: mutations leading to a truncated protein in episodic ataxia type 2 (EA2), small expansions of a CAG trinucleotide in spinocerebellar ataxia type 6 and also in three families with EA2 features, and, finally, a missense mutation in a single family suffering from episodic ataxia and severe progressive PCA. We screened 16 families and 3 nonfamilial case patients affected by HM/PCA for specific CACNA1A mutations and found nine families and one nonfamilial case with the same T666M mutation, one new mutation (D715E) in one family, and no CAG repeat expansion. Both T666M and D715E substitutions were absent in 12 probands belonging to pure HM families whose disease appears to be linked to CACNA1A. Finally, haplotyping with neighboring markers suggested that T666M arose through recurrent mutational events. These data could indicate that the PCA observed in 20% of HM families results from specific pathophysiologic mechanisms.

Abstract
The different steps of development of chemically induced brain tumors were investigated in rats by MRI using a superparamagnetic contrast agent, magnetite-dextran nanoparticles (MD3). Sprague Dawley strain pregnant female rats were injected intravenously with ethylnitrosourea solution at the end of pregnancy. Offspring whelped by the inoculated mother were followed. MRI examinations were performed at 0.5 T. MD3 nanoparticles were injected intravenously at a dose of 5 mg Fe kg(-1) body weight 30 min before rat sacrifice. After sacrifice, histological slices were stained with hematoxylin-eosin. Relaxation times were measured at 40 MHz and 37 degrees C. MD3 nanoparticles act differently according to the step of the tumor development. Before tumor appearance, at a step characterized by the presence of abnormal cell clusters, relaxation time T2 increased significantly. The T2-weighted image showed a small increase in signal intensity in the lesion. Image contrast was improved by MD3 nanoparticles injection because of the decrease in healthy tissue signal intensity. The T1-weighted image did not provide any additional information. In presence of a minute tumor, relaxation times decreased in tumor but increased in surrounding tissue. The T1-weighted image showed a hypersignal on the border of an hyposignal. T2-weighted image showed a hypersignal in the same area. Signal intensity was not modified after MD3 nanoparticles injection. When new vascular capillaries developed in the tumor, MD3 nanoparticles cross into the cerebral parenchyma. Transmission electron microscopy showed magnetite crystals in this specific area on cytoplasm vesicles of glial cells and in tumor-specific membrane arrangements. On T2-weighted image, the hypersignal consisted of a well defined part and a second more fuzzy part, its signal being extinguished after MD3 nanoparticles injection. Necrotic areas and edema can be discriminated. The use of such a superparamagnetic contrast agent would be helpful in early detection of tumor development and in improving distinction of tumor mass from its vascular environment in patients.

Abstract
Modifications of water state were analyzed during ethylnitrosourea-induction of brain tumor in rats. Four different steps were identified in the cancerization process according to NMR and histological findings. Two analogies were observed in the pattern of bound' water at decreasing temperatures: first the pattern was similar in tumor area and white matter, second the pattern was similar in the same area of normal brain tissue and cortical gray matter. This phenomenon, which corroborates previous reports on liver cancerization, points out that pathological proliferation of glial cells, and their progressive organization into multiple layers, is accompanied by a transformation of water properties at the cellular level.

Abstract
High-resolution one-dimensional proton and phosphorus and two dimensional COSY proton Magnetic Resonance Spectroscopy were used to investigate the lipid and carbohydrate metabolism of human brain tumors. Sixteen meningioma (MG) (benign tumors) and ten glioblastoma (GB) (malignant tumors) samples from brain surgery were treated for dual extraction of lipidic and aqueous phases before NMR processing. A highly significant variation of the 1H metabolite spectral pattern was observed between benign and malignant tumors. Double extraction method combined with both 1H and 31P NMR in vitro analyses provided a large set of biochemical information which may be statistically analyzed to elucidate tumor-specific biochemical pathways and to improve interpretation of in vivo spectra.

Abstract
We have studied the action of peripheral blood lymphocytes (PBLs) and intrathyroidal lymphocytes (ITLs) on the biochemical and hormonal metabolism of autologous thyrocytes cultured in follicles in a collagen gel. The production of tumour necrosis factor alpha (TNF-alpha) in culture was also measured. Thyroid tissues and lymphocytes were obtained from ten patients with Graves' disease and from five control subjects. Lymphocyte-induced cytotoxicity was evaluated in autologous thyrocytes cultured in a collagen gel by several tests; neutral red uptake, lactate dehydrogenase activity and glutathione level. Hormonal metabolism was assessed by evaluating tri-iodothyronine (T3) and total cAMP production under TSH stimulation. TNF-alpha levels were measured in supernatants after 5 days of coculture. PBLs altered biochemical metabolism, T3 synthesis and cAMP production in autologous thyroid follicles. These inhibitions were greater than those obtained with ITLs. No difference was seen between cells obtained from patients with Graves' disease and those from normal subjects. TNF-alpha levels secreted by PBLs were higher than those secreted by ITLs. The concentrations of this cytokine decreased in coculture. Significant correlations were observed between the decrease in biochemical and hormonal parameters and TNF-alpha levels. Exogenous TNF-alpha and high doses of interferon gamma inhibited follicle metabolism, especially hormone secretion. In conclusion, thyrocytes cultured in follicles provide a more sensitive model than monolayer cultures for analysis of lymphocyte-induced interactions. Lymphocytes gradually inhibit the biochemical and hormonal metabolism of autologous thyroid follicles depending on the isolation method. These alterations may be particularly attributed to TNF-alpha secreted by lymphocytes. The cytokine-induced inhibition of thyroid hormonal function apparently involves the adenylate cyclase system.

Abstract
In medullary carcinoma of the thyroid (MTC), drug resistance remains the major obstacle to effective chemotherapy. In this work, we studied the effect of S9788 on doxorubicin (DOX) efficiency in a MTC cell line (TT cells) injected in nude mice. After two passages, TT cells were injected in 40 nude mice divided into four groups [controls and groups receiving DOX alone (10 mg/kg), S9788 alone (50 mg/kg) or both DOX + S9788]. The weight of the mice, tumoral volume (TV), doubling time (DT) of the tumor and survival time of mice were evaluated in each group. In addition, the efficiency of DOX with or without S9788 was assessed by the inhibition of tumoral growth and specific growth delay. In vitro, glycoprotein P 170 (P-gp) was detected on tissular sections and on tumoral cells by immunocytochemistry or flow cytometry with several monoclonal antibodies: JSB1, MRK 16, C219 and UIC2. In vivo the weight of the mice decreased slightly with DOX and dropped dramatically with DOX + S9788. The DT of the tumors increased with DOX over controls (22.5 +/- 8.5/12.7 +/- 3.9 days) and showed a higher value with DOX + S9788 (29.2 +/- 11.4 days). Inhibition of tumoral growth, 89% with DOX, fell to 47.6% with DOX + S9788. Specific growth delay increased with the double treatment (130 versus 75% with DOX alone). In vitro, P-gp was not detected on tissular sections and cells whatever the method and the antibody used. In conclusion, S9788 potentiates the efficiency of DOX treatment in vivo. The absence of P-gp may result from the absence of translation of the MDR1 gene. The reversal effect of S9788 may involve another resistance mechanism such as the MDR Sister of MRP.

Abstract
In a previous study, we identified regions on the surface of tumor cells which act as acceptor sites for putrescine (Put) and studied the competition between structural analogs of Put (N,N'-tetramethyl-alpha,omega-diaminoalkanes) and Put bound to latex microspheres. A chain of four to seven carbons was necessary for inhibition of Put-latex binding to the cell surface of human glioblastoma (U251) cells. We show here that under the experimental conditions, N,N'-tetramethyl-1,4-butanediamine and N,N'-tetramethyl-1,7-heptanediamine exhibit an antitumor effect. In a first step (1-48 h after treatment), cells exposed to these compounds show large intracellular vacuoles. We failed to detect any acid phosphatase activity in these intracellular structures revealing that they were not lysosomes. Electron microscopy observations argue for the conclusion that these vacuoles are an hypertrophy of the endoplasmic reticulum (ER) and/or of the Golgi vesicles. Our hypothesis is that this typical effect of the analogs reveals that ER could be a physiological target of endogenous polyamines. At a later stage (6 days after treatment), the cells undergo morphological and biochemical changes: thin and long expansions characterize the cells and the GFA protein is overexpressed. Correlated to both these effects, karyotypic modifications are found in chromosomes 3 and 6. These changes evoke a differentiation of the treated cells. The work provides evidence that N-methylated polyamine analogs taking the place of endogenous putrescine demonstrate a hopeful antitumor effect.

Abstract
Case report of the appearance of a highly malignant cerebral non-Hodgkin's lymphoma of a diffuse large cell type, type B, occurring at the immediate onset of chemotherapy for a stage IV (mediastino-pulmonary) Hodgkin's disease (nodular sclerosis) diagnosed in a 16-year-old boy. The treatment of this cerebral lymphoma associated primary chemotherapy with high dose methotrexate, high dose aracytine, etoposide, and ifosfamide. The chemotherapy proved to be highly efficient, producing complete remission. Thoracic and abdominal irradiation for Hodgkin's disease was performed concomitantly with chemotherapy for the non-Hodgkin's lymphoma. This treatment was followed by 36 Gy of cerebral irradiation. Thirty-six months after the discovery of the cerebral non-Hodgkin's lymphoma the patient was still disease-free and doing well.

Abstract
An unusual protocol based on a preliminary clinical study on cylindromas metastasized to the lung was proposed to brain glioma patients: Day 2 100 mg/m2 i.v. Cis platinum (Cis PII) followed at days 3 and 5 by 6 Gy irradiation (RT) in two fractions and three days. Five cycles were scheduled at 21 days interval. On disease progression a three fractions per day radiotherapy regimen (3 FRT) in split-course (two series of 22.50 Gy in 15 fractions and five days separated by a two weeks period of rest) was then delivered to the patients. All patients had a measurable mass on the CT scan. 19 were entered into the study: 13 as first line therapy (group A) and six for salvage treatment (group B). Tolerance was globally good. Eight patients were considered responders at the end of five cycles of Cis PII-RT. They were all group A patients. Median symptom-free interval was six months for the whole population. Survival was twelve months. The 3 FRT was well tolerated but does not seem to have improved the therapeutic gain of the chemoradiotherapy combination. The present study concerns patients whose prognosis was poor on inclusion: surgery inadvisable or unsatisfactory and diagnosis mainly based on biopsy only. The number and the duration of responses justify further study into Cis PII as first line therapy as either an effective cytotoxic drug or a potential radio enhancer.

Abstract
An almost complete prevention of tumor growth was achieved in U-251 human glioblastoma xenografted nude mice, by partial decontamination of the gastrointestinal tract and feeding of a polyamine-free diet containing inhibitors of ornithine decarboxylase (DFMO) and of polyamine oxidase (MDL 72527). After one week of polyamine deprivation, spermidine concentrations were lowered, and spermine levels were increased in all tissues. In contrast, putrescine concentrations were only reduced in tumor and in brain. Erythrocyte polyamine determinations revealed differences similar to those observed in tissues: spermidine concentration was lowered by 50% and spermine level was 3-fold increased. If this or related treatments should become of therapeutic importance in the future, then the determination of erythrocyte polyamine levels might be of diagnostic value.

Abstract
Since the polyamine metabolism system is very active in proliferative glioma cells, polyamine linked drugs are to be considered as potential antineoplastic agents against malignant gliomas. This study reports the trial of a new compound lineage, the Polyamine Linked Cyclophosphazenes, on human glioblastoma heterografts in nu-nu mice. Two agents are tested: DIAM 3 and DIAM 4. Both show an important antineoplastic action either on a chronic treatment schedule or as single dose. Systemic tolerance is satisfactory.

Abstract
ALDH activity measured fluorimetrically using a high concentration of aliphatic aldehyde as substrate was studied in human glioblastomas grafted in nude mice. Compared with normal brain, ALDH activity is significantly increased in malignant glioma tissue, especially in the cytosolic subcellular fraction. Correlatively, in comparison with normal brain tissue, MDA levels were significantly reduced in whole homogenates and in cytosolic fractions of xenografted glioblastoma tissue. Preliminary results concerning human malignant glioma biopsies are in good agreement with our experimental data. In view of previous works, these results suggest a relationship between alterations in ALDH iso-enzymes activities and cytosolic aldehyde concentrations with respect to normal or tumoral cell growth.

Abstract
Treatment of gliomas remains disappointing in spite of a great number of experimental biological data and of randomized therapeutic studies. This could be partly explained by the inefficiency of our conventional methods to assess the regional metabolism of these tumors. The use of positron emission tomography (PET) brings encouraging possibilities in this field. We report our preliminary experience of measuring regional cerebral methionine uptake with PET after intravenous injection of [11C]L-methionine. Twenty-two patients with histologically confirmed gliomas were studied. An ECAT II positron emission tomograph was used for scanning. The position of the plane was chosen to include a major section of the tumor in the reconstructed brain slice. The protocol required a two-step examination: 1) after injection of 15 to 25 mCi of [11C]L-methionine, 12 scans were performed over a period of 46 minutes; and 2) 18 hours later, regional cerebral blood volume was measured in the same slice after intravenous injection of 2 to 4 mCi of 68GaCl3. The tumoral region of interest was determined as being the area of maximum activity. For each patient we calculated the ratio, R, between the activity in this tumor region of interest and the activity in the contralateral healthy symmetric region of interest which was used as an "internal standard" for the same patient. We correlated the ratio R with the histological grading. In 22 patients, mean values of R were calculated for each tumor: Grade II (n = 5): R = 1.04 +/- 0.27; Grade III (n = 5): R = 1.68 +/- 0.22; and Grade IV (n = 12): R = 2.33 +/- 0.86.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The differentiation potential of the human retinoblastoma cell lines Y-79 and WERI-Rb1 was evaluated in vitro for up to 120 days in a matrix system and in rotary suspension for 30 days. Matrix cultures were grown with 10% fetal calf serum (FCS), with and without differentiation-promoting agents. The latter were applied for a total of 5-45 days (usually 30 days) and included 7S nerve growth factor, dibutyryl cyclic AMP, sodium butyrate, retinoic acid, hydrocortisone, and ascorbic acid. Fully defined, serum-free medium and medium containing 5 or 15% FCS were also used for matrix cultures, and medium with 5 or 10% FCS for suspension cultures. By immunoperoxidase (performed on matrix cultures, both untreated and treated for 30 days with differentiation-promoting agents), the cells of both lines were positive for neuron-specific enolase (NSE), microtubule-associated protein 2 (MAP2), class III beta-tubulin (human h beta 4) isotype, and synaptophysin. In addition, the WERI-Rb1 cells expressed 200 kd neurofilament protein (NFP-H) and retinal S-antigen. Both lines were invariably negative for glial fibrillary acidic (GFA) protein, myelin-associated glycoprotein, myelin basic protein, the epitope recognized by the Leu-7 monoclonal antibody, opsin, and hydroxy-indole-O-methyltransferase. In the Y-79 line the presence of NSE and the absence of NF proteins-H, -M and -L, of GFA protein, and of retinal S-antigen were confirmed biochemically. No differentiated features were found by electron microscopy in either line. Thus, in the matrix system employed, both lines exhibited solely a potential for neuroblastic differentiation, which was more advanced in the WERI-Rb1 line, as reflected by the antigenic expression of NFP-H and of retinal S-antigen.

Data obtained during post-surgical monitoring (2 to 28 months) of 32 histologically confirmed malignant supratentorial glioma patients, are reported here. It was observed that: whatever the grade of malignancy, 100% of the patients whose tumor recurred showed, on at least one occasion, abnormal red blood cell (RBC) spermidine (SPD) (greater than 14 nmoles/8.10(9) RBC) or spermine (SPM) (less than 2 nmoles/8.10(9) RBC) levels. 30% of the patients whose tumor recurred had abnormal RBC polyamine concentrations, one to six months before any other sign of tumor progression. In patients with normal RBC polyamine values, clinical and tomodensitometric indications of tumor progression have to be reconsidered. During individual follow-up, RBC SPD levels of each patient were generally significantly correlated to those of SPM, and the slopes of their straight regression lines (SRL) appeared to be related to the importance of the intracranial cell proliferation. In such conditions we established the regression equation of the group of all recurring patients taken together. We propose a graphic model, including a space corresponding to RBC SPD and SPM levels observed in case of tumor recurrence, which can be utilized routinely in neuro-oncology during the monitoring of post-operative malignant supratentorial glioma patients.

Abstract
137 samples of intracranial tumours have been studied in proton NMR spectroscopy. T1 and T2 relaxation times are above those of normal grey and white matter. Differential diagnosis between benign and malignant brain tumours does not seem feasible upon proton T1 and T2 alone. Histological correlations allowed us to specify secondary changes accounting for T1 and T2 variations (oedema, microcyst, stroma reaction, necrosis).

Abstract
Brain protein synthesis may be evaluated in vivo by a PET three compartment methionine model. 14 human brain tumor patients were studied. Protein synthesis rate (PSR) was increased in any glial tumor even in low grades, but this increase was statistically more important in anaplastic tumor. Radiotherapy action was evaluated in two patients. Local tumoral PSR was reduced to normal brain PSR after treatment. No difference was seen in normal cortex contralateral to the lesion between pre and post radiotherapy examination. 11 C-L-Methionine incorporation measured by PET looks as a very sensitive method for studying tumor metabolism and treatment effects.

Abstract
Polyamine levels have been studied in brain tumor patients. We focused our study on the relationship between tumor, cerebrospinal fluid (CSF) and red blood cell (RBC) polyamine levels. Our results are the following: Polyamine levels in CSF are consistently increased, whatever the histological type may be. The highest tumoral concentrations are found in medulloblastoma. In glioblastomas, the RBC spermidine levels are higher than in the other types of tumors and there is a highly significant correlation between the spermidine/spermine ratio in tumor and RBC. Therefore, RBC polyamine determination might be of clinical interest in the monitoring of patients with glioblastomas.
