Abstract
We investigated the molecular mechanisms involved in the glucose carrier (Glut 1) regulation in FRTL-5 cells and two derived transformed clones (SRC and Ki-Mol cells). When compared to the wild-type strain, SRC and Ki-Mol cells showed an increase in both glucose consumption and uptake (about 60 fold), associated with 6-8 fold higher Glut 1 mRNA levels. Transcriptional studies revealed a 2- to 3 fold increased activation of the gene in the transformed cells, suggesting that transcription alone cannot fully account for the higher Glut 1 gene expression. Western blot studies showed an increase of the Glut 1 protein in SRC and Ki-Mol cells, associated with a different gel migration pattern and a disparate distribution rate between the plasma membrane and the microsomal fraction. These data indicate that the higher rate of glucose uptake observed in SRC and Ki-Mol cells is associated to an increase in Glut 1 gene expression, and that also changes in the subcellular distribution and probably in the structure of Glut 1 protein are present.

Abstract
A parallel study of the modification in the opioid and immunological systems induced by acute restraint (RT) was carried out in male and female rats 24 hr after the treatment. beta-Endorphin-like immunoreactivity (beta-ELI) was measured in two brain areas (ventral hypothalamus [HYP] and periaqueductal gray matter [PAG]) and in the pituitary (anterior and neurointermediate lobes), together with plasma corticosterone (C) and ACTH. Immune function was measured as mitogen-induced Interferon-gamma (IFN-gamma) production by splenocytes. RT reduced beta-ELI levels in the PAG in males and females. Plasma levels of C and ACTH did not differ from the basal levels in restrained animals. RT reduced IFN-gamma production in both sexes, but this effect was more marked in females than in males. The possible relationship between the immune and opioid system is discussed.

Abstract
We characterized the structure and the function of insulin receptors isolated from 10 human breast cancer specimens. We observed that the insulin receptor content, as determined by a specific radioimmunoassay, was four fold increased in human breast cancer tissue when compared to normal breast tissues. In both cancer and normal breast tissues, insulin receptor mRNA consisted of two major species of approximately 11.0 and 8.5 kilobases. The size of the insulin receptor alpha subunit was determined by 125I-insulin cross-linking followed by immunoprecipitation and polyacrylamide gel electrophoresis; a value of 135kDa was observed for receptors from both breast cancer and normal breast tissues. The functional binding ability of insulin receptors from cancer tissues was slightly lower as compared to normal tissue derived insulin receptor (% B/T = 2.22 +/- 0.50 per ng of insulin receptor as determined by radioimmunoassay vs. 2.96 +/- 0.49, mean +/- S.E.M.). The concentration of insulin that caused half maximal inhibition of 125I-insulin binding was very similar for both cancer and normal breast receptors (80pM). The size of the insulin receptor beta subunit as determined by receptor autophosphorylation was 95kDa. Basal and maximal insulin (100nM) stimulated receptor tyrosine kinase activity, in terms of both receptor autophosphorylation and phosphorylation of an exogenous substrate, was similar in malignant and normal breast tissue derived insulin receptor. Also, a very similar insulin stimulated Km value for ATP was showed by the tyrosine kinase of insulin receptors from breast cancer and normal breast tissue (11.1 and 10.8 microM ATP, respectively). However, in insulin receptors from breast cancer tissue the average tyrosine kinase sensitivity to insulin, as calculated on the exogenous substrate, was higher, although not significantly, with respect to normal breast tissue (ED50 at 0.28 +/- 0.09 and 1.08 +/- 0.33 nM insulin, respectively). A similarly different sensitivity to insulin was observed also for receptor autophosphorylation. In conclusion, this study demonstrates that breast cancer tissues have an increased number of structurally and functionally normal insulin receptors. In some breast cancer tissues, however, the sensitivity of the receptor tyrosine kinase activity to insulin is greatly increased. These data suggest that, in vivo, the mitogenic effect of insulin may play a role in the biology of certain breast cancers.

Abstract
Inhibin and activin are referred to as gonadal glycoprotein hormones whose function is the control of FSH release from the pituitary gland. However, several observations indicate that inhibin and activin are produced in various organs and serve multiple functions. Because bone marrow and spleen produce inhibin and activin, our aim was to evaluate their possible effect on cell-mediated immune function. For this reason we studied 1) monocyte chemotaxis, 2) lymphocyte interferon-gamma production, 3) phytohemagglutinin-induced lymphocyte proliferation, and 4) nonmajor histocompatibility complex-restricted and lymphokine-activated lymphocyte cytotoxicity. All studies were performed on human peripheral blood cells in the absence or presence of various doses of inhibin, activin, or inhibin plus activin. A significant dose-related increase in monocyte chemotaxis was induced by inhibin. Activin increased the migrational activity of monocytes, but via random, not directed, migration. Inhibin significantly decreased interferon-gamma production, and its effect was reversed by activin. Inhibin and/or activin had no significant effect on either phytohemagglutinin-induced lymphocyte proliferation or lymphocyte cytotoxic capability. The present demonstration that inhibin and activin may affect some immune parameters suggests a possible involvement of these hormones in regulating cell-mediated immune function.

Abstract
There is increasing evidence that neuropeptide modulation of the immune response is an important physiological phenomenon which involves the interaction of peptidergic neuromodulators with specific neuropeptide receptors on the plasma membrane of immune effector cells. Many studies have examined the effect of neuropeptides on mitogen-induced lymphocyte proliferation and immunoglobulin synthesis but very little is known about specific lymphokine production. In this study, we describe the effect of somatostatin (SOM) and vasoactive intestinal peptide (VIP) on interferon gamma (IFN-gamma) production by normal human peripheral blood mononuclear cells (PBMC) stimulated in vitro with polyclonal T cell activator staphylococcal enterotoxin A (SEA). Our findings provide experimental evidence that both SOM and VIP reduce the IFN-gamma production by SEA-stimulated PBMC. This reduction was time- (with maximal effect at 72 h) and dose-dependent (at doses as low as 10(-11) M with maximal effect at concentrations between 10(-9) and 10(-8) M of neuropeptides). This effect was absent in resting PBMC. The meaning of inhibitory effect of VIP and SOM on IFN-gamma production and its role in immune response in vivo are discussed.

Abstract
TSH-induced proliferation of FRTL5 cells was studied in a chemically serum-free, defined medium. FRTL5 cells incubated for several days in a medium lacking of serum and hormones were fully able to respond to TSH in terms of cAMP production and iodine uptake. In the same medium, TSH stimulated FRTL5 cell growth as assessed by thymidine incorporation, DNA content and cell count. In these experimental conditions the cellular doubling time was of 7.5 days as compared to 40 h when calf serum was present together with TSH. Cholera toxin, forskolin and (bu)2cAMP, substances able to selectively increase intracellular cAMP levels, were not as efficient as TSH in inducing FRTL5 cell growth. However, both TSH and (bu)2cAMP, in a similar way, induced c-myc gene expression and cellular progression through the prereplicative phase of cell division. These data demonstrate that cAMP-dependent mechanisms are only partially responsible for TSH-induced FRTL5 cell growth, thus suggesting a role of cAMP-independent mechanisms.

Abstract
The authors report their experience in a radiographic study of the treatment of 22 cases of fractures of the acetabulum. All the patients were studied using both traditional radiography and CAT, and the results were then compared. In 17 cases (77%) the CAT images were integrated with a tridimensional reconstruction (3D). The diagnostic aid provided by CAT was of crucial importance in planning treatment and selecting the most suitable surgical approach. Furthermore, 3D reconstruction may provide a valuable link between traditional radiography and CAT in evaluating complex fractures. The authors conclude that a comprehensive radio-diagnostic study should be a routine preoperative procedure in complex fractures of the acetabulum, and in all cases where traditional radiography yields doubtful results.

Abstract
In most cases of brain stem expansive lesion a surgical approach is possible, but in each patient it must be evaluated if the surgical risk is proportional to the therapeutic result. Sometime surgery is limited to a biopsy sample, particularly in malignant lesions. We started stereotactic serial biopsy sampling in all CT or NMR intraaxial brain stem expansive lesions as a preliminary diagnostic procedure. The aim is to look for benign well delimited lesions that we consider for surgical removal or to drain haematomas and abscesses. 35 patients with brain stem expansive lesions were submitted to 47 surgical procedures: 35 stereotactic biopsies (one each patient) and, among them, 12 were major surgical procedures (with craniotomy) for microsurgical removal of the expansive lesions. 15 patients were in paediatric age. Suboccipital transcerebellar approach was performed in 25 mesencephalic, pontine, bulbar expansive lesions and frontal approach was limited to 10 thalamo-mesencephalic lesions. There was no mortality. Two patients were stereotactically drained and definitively cured.

Abstract
In recent years, receptors for calcitriol (the active form of vitamin D3) have been identified in monocytes and activated, but not resting, human B and T lymphocytes suggesting that it may be involved in immune regulation. Because lymphokines are central in the regulation and modulation of immune or inflammatory responses and since the calcium translocation is involved in the mitogen-induced activation of lymphocytes, we thought it interesting to study the role of calcitriol on interferon gamma (IFN-gamma) production in vitro. In this study, we report that calcitriol inhibits the IFN-gamma production by staphylococcal enterotoxin A-stimulated peripheral blood mononuclear cells (PBMC) in a dose-dependent fashion. The inhibitory effect was less potent in calcium ionophore A23187-stimulated PBMC and was absent in resting PBMC.

Abstract
We report on 11 patients who in 1980-1982 had bladder reconstruction, after cystectomy for bladder cancer, utilizing the ileocecal valve as an antireflux mechanism and a direct urethrocecal anastomosis. They received preoperative irradiation (2,000 rad) and had some early complications such as pelvic abscesses and temporary urinary fistulas. We have since omitted preoperative radiation on cases performed in 1984-1987 and they did not have these complications.

Abstract
CT diagnosed brain stem malignant lesions were in the past almost always treated with radiation therapy (RT). Eventually this turned out to be a grave mistake. With stereotactic serial biopsies of all brain stem expanding lesions we have been able to verify the histological nature in all cases but two and to prevent a blind therapeutic approach. In 24 patients bearing CT diagnosed expansive lesions into the brain stem 68 samples were taken during 24 stereotactic procedures. In 8 patients surgical removal of the expanding lesion was attempted after stereotactic biopsy.

Abstract
When human recombinant interferon-alpha 2 diluted in saline was injected s.c. into rabbits, the total amount recovered in thoracic lymph was less than 0.4%. Recoveries increased from 2- to 8-fold if interferon was injected in 4% albumin or with hyaluronidase, respectively. Albumin added to interferon acts as an interstitial fluid expander, thus favoring interferon absorption through lymphatics rather than blood capillaries. This strategy may increase the therapeutic index of interferon.

Abstract
By neutralization tests using anti-rat and mouse interferon (IFN) antibodies, we tested whether the antiviral activity present in abdominal lymph but absent in plasma of healthy rats, could be ascribed to IFN. Antimouse IFN-gamma antibodies neutralized the inhibitor completely while anti-rat IFN-alpha/beta antibodies did not. We conclude that rat lymph contains traces of IFN-gamma and that the antiviral activity is not due to low-density lipoproteins, immunoglobulins, or to cell-produced viral inhibitors. This finding extends previous observations on rabbit lymph and further supports the existence of a physiological low-level interferon response.

Abstract
If interferon is produced by the gut-associated lymphoid tissue of healthy rabbits under normal conditions and is not all bound in situ, it may spill over and be detectable in lymph. We therefore measured antiviral activity in lymph and plasma simultaneously. We found that antiviral activity was consistently measurable in abdominal and thoracic lymph but not in plasma or in the lymph collected from the hind leg duct. The antiviral activity was neither due to lipoproteins, nor immunoglobulins, nor to cell-produced viral inhibitors other than interferons. Extensive characterization of the antiviral activity indicated that the inhibitor is either rabbit interferon gamma or an acid-labile interferon alpha or a mixture; appropriate antisera will be necessary to resolve this uncertainty. The results support the view of the existence of a physiological interferon response.

Abstract
Cells attached to intrauterine devices (IUDs) release interferon (IFN) in the medium during incubation in vitro. Most of the IFN is released during the first hour suggesting that the cells had been previously induced and were probably already producing IFN in vivo. Characterization of the IFN indicates that most of it is of gamma-type with a trace of alpha. Production of IFN in the uterine fluid would represent a first example of the physiological IFN response and may serve to modulate some of the mechanisms preventing implantation of blastocyst. The actual presence of IFN in the uterine secretion remains to be demonstrated.

Abstract
An investigation was made of the distribution and the ontogenesis of various types of receptors in the bladder detrusor muscles and sphincter isolated from human fetuses at different stages of pregnancy. Cholinergic receptors appear very early in the fetal urinary bladder since contractile responses to bethanechol, competitively blocked by atropine, are observed in detrusor muscle preparations at three months and in the sphincter at four months. Later on, the density of cholinergic receptors increases in the detrusor muscle whereas there is a progressive reduction in the sphincter.

Abstract
Erythrocytes incubated in different protein-free media release vesicle other than glycopeptides. The presence of glucose blocks the release of glycopeptides almost completely but not the vesiculation phenomenon. In vitro ageing of erythrocytes provokes a marked discocyte-spheroechinocyte transformation and a redistribution of membrane components.

Abstract
Organochlorine pesticides and their degradation products can affect humans in several ways and are detected in human tissue, including placental tissue and umbilical cord blood. We report the results of preliminary research conducted to determine the levels of p-p'DDT in maternal and umbilical cord blood during labor and to estimate the possible consequences of this product for calcium metabolism. The results confirm that p-p'DDT is transferred to the fetus through the placenta and indicate the existence of a complex fetal-maternal p-p'DDT distribution mechanism.

Abstract
Following a review of the literature, 2 cases of angioimmunoblastic lymphadenopathy with dysproteinaemia are reported. Anatomo-pathological examination of the lymphonodes shows widespread change in the structure with vascular and lympho-immunoblastic proliferation and deposit of amorphous eosinophil substance. The most significant clinical and morphological aspects are reported and these are related to the therapeutic response. The effectiveness of cortisone therapy is shown by comparison of laboratory examination data at admittance and after three months.

Abstract
A quantitative analysis of the modifications undergone by the vascular networks and the perivascular spaces in the rudiment of the adenohypophysis has been carried out in normally developing chick embryos from the 7th incubation day to hatching. The present results point to the existence, during the developmental period mentioned, of a relationship between the extent of the capillary bed and, respectively, of the perivascular spaces, the gradual increment of the former being paralleled by a decrease of the latter. The rate of these events appears to be higher between the 14th and the 16th incubation days, namely when the vessels begin to acquire some of the morphological features typical of sinusoids, their thin walls getting gradually into closer contact with the secretory epithelial cells.

Abstract
Chronic atrophic gastritis and a sessile polyp were diagnosed during gastroscopy of a patient with splenomegaly and portal hypertension. The polyp was removed endoscopically. Histologically, it proved to be an endocrine tumour, which was identified as gastrinoma by immunohistochemistry. Then, hypergastrinemia was found and gastrectomy was performed to ensure complete removal of the tumour. The surgical specimen showed G cell hyperplasia of the antro-pyloric mucosa and severe atrophic gastritis with scattered argyrophil micronodules in the corpus-fundus region. 3 years after this treatment the patient is well.
