Abstract
Two scales based on the Fagerstrom Tolerance Questionnaire were developed to measure dependence in smokeless tobacco users. The total score for both scales correlated positively with saliva cotinine levels in subjects, and several individual items produced equally positive correlations. Regression analyses yielded two subsets of three items from each scale that predicted cotinine level. Reports of using smokeless tobacco within 30 min of waking served as a predictor in both models. For the purposes of measuring smokeless tobacco dependence, attention should be given to individual items correlated with saliva cotinine levels that could be used to determine the direction of cessation efforts. Future research should also develop additional items specific to the use of snuff or chewing tobacco and eliminate questions not contributing to the overall scale.

Abstract
BACKGROUND Studies show sustained levels of nicotine among young males using smokeless tobacco, causing concern for subsequent cardiovascular risk. Also, there is little information on effects of nicotine replacement on cardiovascular risk in cessation programs. This study investigates the effects of nicotine gum replacement in smokeless tobacco cessation on cardiovascular risk factors. METHODS Smokeless tobacco users, ages 18-65, were randomly assigned in a double-blind fashion to 2-mg nicotine or placebo gum. At baseline, Week 4, and Week 8, dependent measurements, heart rate, blood pressure, and weight were recorded, and fasting lipoprotein profiles were drawn. RESULTS This paper focuses on the smokeless tobacco users who refrained from use during the study period (N = 56). The nicotine gum group weighed less (P = 0.033) than the placebo group throughout the study and weight increased at a significant rate between Weeks 4 and 8 for both groups as gum decreased. Triglycerides were higher for the nicotine gum group than the placebo group (P = 0.031), with triglycerides decreasing between Weeks 4 and 8, with a similar effect seen among nonabstinent smokeless tobacco users. There was no dose, time, or dose by time effect for the other dependent measures. CONCLUSIONS Among smokeless tobacco users who were abstinent, weight increased, with subjects on nicotine gum weighing less throughout the study. The lipoprotein profile, heart rate, and blood pressure did not improve over time, contrary to smokers in whom HDL increases and heart rate decreases with cessation. This could relate to different routes of administration, pharmacokinetics, or by-products of tobacco smoking being absent in smokeless tobacco. In addition, nicotine gum appeared to have neither an adverse nor a positive effect on heart rate, blood pressure, LDL, HDL, or total cholesterol.

Abstract
We have examined the inheritance of 20 rapeseed (Brassica napus)-specific RAPD (randomly amplified polymorphic DNA) markers from transgenic, herbicide-tolerant rapeseed in 54 plants of the BC1 generation from the cross B. junceax(B. junceaxB. napus). Hybridization between B. juncea and B. napus, with B. juncea as the female parent, was successful both in controlled crosses and spontaneously in the field. The controlled backcrossing of selected hybrids to B. juncea, again with B. juncea as the female parent, also resulted in many seeds. The BC1 plants contained from 0 to 20 of the rapeseed RAPD markers, and the frequency of inheritance of individual RAPD markers ranged from 19% to 93%. The transgene was found in 52% of the plants analyzed. Five synteny groups of RAPD markers were identified. In the hybrids pollen fertility was 0-28%. The hybrids with the highest pollen fertility were selected as male parents for backcrossing, and pollen fertility in the BC1 plants was improved (24-90%) compared to that of the hybrids.

Abstract
With increasing waiting lists for admission to hospital, the aim of this study was to investigate the reliability of an orthopaedic waiting list. Questionnaires were sent to every patient listed as waiting for more than three months. The questionnaire addressed the current symptoms and the current need for surgical treatment. In case of no reply, a further evaluation was done before eventual removal from the waiting list. Of 809 questionnaires mailed, replies were received from 409. A total of 376 were removed from the list, including 111 due to registration errors in the central data base. This study has shown how the indication for operation changes during the waiting period but also that information from data bases can be most unreliable. We find the reasons so general, that we recommend a corresponding evaluation of other waiting lists. Altogether, today's waiting list is faulty and thus provides a wrong basis for management.

Abstract
The effects of adrenaline on skeletal muscle differ between fibre types. The aim of the present study was to investigate the beta-adrenoceptor density, affinity and subtype in rat skeletal muscles with different fibre type composition. beta-Adrenoceptors were determined in cryostat sections to avoid methodological problems with variable recovery, using the non-selective beta-adrenoceptor ligand [3H]CGP-12177 and beta 1- and beta 2-selective cold ligands CGP 20712A and ICI 118,551. In the presence of protease inhibitors [3H]CGP-12177 binding was stable, saturable, reversible, and displaceable. Scatchard analysis of binding saturation data was compatible with a single class of specific binding sites. Binding site density (Bmax) was higher (P < 0.02) in adult soleus (9.38 +/- 1.13 fmol x mg protein-1) than in adult extensor digitorum longus (4.74 +/- 0.39 fmol x mg protein-1), whereas the dissociation constants (Kd), 0.37 +/- 0.05 and 0.31 +/- 0.04 nM for soleus and extensor digitorum longus, respectively, were not significantly different. For young rats (5-6 weeks), Bmax was 11.21 +/- 0.33 and 5.45 +/- 0.11 fmol x mg protein-1 (P < 0.05), and Kd was 0.27 +/- 0.02 and 0.24 +/- 0.04 nM for soleus and epitrochlearis, respectively. These results correspond to a receptor density of 2 and 1 pmol x g w.wt.-1 in muscles containing.mainly type I and type II fibres, respectively. Displacement studies with CGP 20712A and ICI 118,551 were compatible with mainly beta 2-adrenoceptors, but 7-10% beta 1-adrenoceptors were present in both types of muscle.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The homeodomain protein Isl-1 and the proto-oncogene Rhombotin (a LIM-only protein), share a double zinc-binding LIM domain and have both been implicated in neural and possibly endocrine development. Isl-1 is expressed in all endocrine cell-types of the islet of Langerhans while Rhombotin mRNA expression was reported in rat insulinoma cells. We have cloned and sequenced Rhombotin cDNA from rat insulinoma (99.4% identical to human and mouse sequences) and demonstrate that it is expressed in normal islets, intestinal tissue, and testis, in addition to the brain; but absent in all other organs tested. Rhombotin mRNA is expressed in phenotypically distinct islet tumours (α-, β, and δ-tumours) at levels comparable to that of normal islets. Antisera raised against two distinct epitopes contained within a short synthetic peptide representing part of the N-terminal LIM domain of Rhombotin surprisingly stain α- and δ-cells, respectively, on sections of rat pancreas. Rhombotin is undetectable by immunocytochemistry using LIM-domain antisera on intact monolayer islet tumor cells or transfected fibroblasts while readily detectable when equipped with a FLAG epitope, as detected with FLAG antiserum. In contrast, recombinant FLAG-Rhombotin is efficiently recognised by Western blotting or immunoprecipitation with all LIM-specific antisera. Almost identical results were obtained with LIM-specific versus homeodomain/C-terminal Isl-1 antisera staining α-cell cytoplasm or all islet nuclei, respectively. We conclude that Rhombotin in addition to Isl-1 is expressed in the islet of Langerhans and propose that the differential staining patterns obtained with antisera towards the LIM domains versus flanking epitopes of both proteins reflect (1) cell-specific protein-protein interactions of these domains or, alternatively, (2) islet cell type specific expression of novel homologous LIM domain proteins.

Abstract
The mediastinum is an uncommon primary site of liposarcoma, which constitutes < 1% of tumors at that site. We report a case of myxoid liposarcoma evaluated with fine needle aspiration biopsy in a 66-year-old male who presented with cardiac tamponade, superior vena cava syndrome and radiologic evidence of a large anterior mediastinal mass. Cytologically the neoplastic cells were strikingly dyscohesive, with ovoid or spindle-shaped, hyperchromatic nuclei. The cytoplasm was abundant and often finely vacuolated with lipid. They were associated with a prominent myxoid, intercellular substance and distinct, arborized capillary structures. Survival is influenced by the tumor cell type and differentiation. The overall prognosis seems to be poorer than that of liposarcomas occurring in other areas. To the best of our knowledge, this is the first reported case of primary mediastinal liposarcoma diagnosed by fine needle aspiration biopsy.

Abstract
The effect of adrenaline on glycogen breakdown in different skeletal muscle fibre types was investigated in the epitrochlearis muscle in vitro. Histochemical studies showed that adrenaline stimulated glycogen breakdown in all three major fibre types, with a higher absolute glycogen breakdown in type IIB fibres compared to type IIA and type I fibres. In biochemical studies we found that the glycogenolytic rate decreased during prolonged incubation with adrenaline, although the percentage phosphorylase in the a form and the concentration of glucose-6-phosphate (G-6-P) remained high. In the dose response studies we found an EC50 of 2.2 x 10(-8) M adrenaline for adrenaline stimulated glycogen breakdown, with an EC50 of 2.0 x 10(-7) M for adrenaline stimulated accumulation of G-6-P, excluding G-6-P as the key inhibitor of phosphorylase a activity.

Abstract
The present study examined the unique and interactive relationships between age and indices of psychopathology (i.e., anxiety, aggression, and depression), with three types of maladaptive cognitions: hopelessness, negative cognitive errors, and attributional bias. Some negative cognitions were not unique to depression and were associated with broader psychopathology. Developmental considerations also influenced some negative cognitions or qualified the association between negative cognitions and depression.

Abstract
Galanin was purified from an extract of the stomach of the rainbow trout, Oncorhynchus mykiss, and its primary structure was established as Gly-Trp-Thr-Leu-Asn-Ser- Ala-Gly-Tyr-Leu10-Leu-Gly-Pro-His-Gly-Ile-Asp-Gly-His-Arg20- Thr-Leu-Ser-Asp- Lys-His-Gly-Leu-Ala. Trout galanin shows six amino acid substitutions compared with pig galanin, but the N-terminal region (residues 1-14) has been fully conserved. The distribution of galanin-immunoreactive (GAL-IR) structures in the trout brain and pituitary was studied via immunohistochemistry. GAL-IR cell bodies were observed only in the caudal telencephalon, the preoptic region, and the mediobasal hypothalamus. GAL-IR fibers, however, are widely distributed throughout the brain, with a much lower density in the midbrain and posterior brain than in the tel- and diencephalon. Particularly dense innervation of the mediobasal hypothalamus, the ventral and supracommissuralis parts of the caudal telencephalon, and the region above and below the anterior commissure was observed. A heavy innervation of the pituitary was consistently detected. GAL-IR fibers were present in neurohypophyseal digitations of both the anterior and intermediate lobes with highest density in the region of the proximal pars distalis, where growth hormone and gonadotropic cells are located. Fibers were also seen in digitations of the rostral pars distalis, in particular between the prolactin follicles. The distribution of GAL-IR neurons in the central nervous system and pituitary of the trout suggests that the peptide may exercise an important role in the regulation of neuroendocrine functions, particularly those related to reproduction.

Abstract
This study assessed the involvement of phagocytic cells in murine resistance to disseminated candidiasis of endogenous origin. SCID mice and their immunocompetent CB.17 (BALB/c) counterparts were colonized with a pure culture of Candida albicans and treated with an antigranulocyte monoclonal antibody (anti-Gr-1), polyinosinic:polycytidylic acid (poly[I.C]), or both to impair macrophage function in vivo. Candida-colonized SCID mice were more susceptible to disseminated candidiasis after treatment with anti-Gr-1 or poly(I.C) than were CB.17 mice. Histopathology of orogastric tissues demonstrated that combined treatments with anti-Gr-1 and poly(I.C) also enhanced the susceptibility of SCID and CB.17 mice to orogastric candidiasis. These data indicate that macrophages as well as granulocytes play an important role in host resistance to mucosal and disseminated candidiasis of endogenous origin.

Abstract
PURPOSE This article addresses the suitability of semirigid fixation for the treatment of mandibular fractures. MATERIALS AND METHODS Between 1986 and 1991, 279 patients with 447 isolated mandibular fractures were treated with miniplate fixation using the tension-band principle of Champy et al. The time from trauma to treatment, etiology, number and location of the fractures, and the presence of preoperative infection and neurosensory disturbances were recorded. Postoperative complications such as infections, neurosensory disturbances, malocclusion, and nonunions also were recorded, as well as the reasons for removal of the miniplates. RESULTS Postoperative infection occurred in 10 patients (3.6%). These infections were controlled by antibiotics and the miniplates were removed after the acute phase. Occlusion disturbances were noted postoperatively in 13 patients (4.7%), and they were corrected by minimal occlusal grinding in the majority of cases. Neurosensory disturbances were noted preoperatively in 26.9% of the patients and 12 months postoperatively in 1.4% of the patients. Forty-seven plates (8.1%) in 32 patients (11.5%) were removed for a variety of reasons. No cases of nonunion occurred. CONCLUSION Semirigid fixation of mandibular fractures with miniplates is a viable treatment option for the management of such injuries.

Abstract
Immune responses to defined antigens of the AIDS opportunistic pathogen Candida albicans that arise as a consequence of alimentary tract colonization or induced candidemia were assessed. Lymphocyte activation and antibody production to the abundant immunodominant antigen enolase were evident in germfree mice colonized with C. albicans. Lymphocytes from colonized or intravenously challenged mice responded to a recombinant C. albicans enolase fusion protein (EFP). The responses to EFP were significantly higher than the responses to a control protein, glutathione S-transferase. In immunoblotting experiments, enolase was the immunodominant humoral immunogen in these mice. These results demonstrate that enolase stimulates cellular and humoral responses and that specific immune responses to enolase are sensitive indicators of the presence of proliferating C. albicans in mice.

Abstract
All first-time admissions from 1970 to 1986 with obsessive-compulsive neurosis (OCD) (ICD-8 diagnosis number 300.39) or obsessive-compulsive personality disorder (OCPD) (ICD-8 diagnosis number 301.49) were analyzed based on an extract from the nationwide Psychiatric Case Register in Denmark. All patients with secondary diagnoses other than neurotic disorders or personality disorders (including "neuroses characterogenes") were excluded from the study. A total of 284 patients were first-time admitted with a main diagnosis of OCD during the period. The sex ratio was 0.67 (males/females). A total of 126 were first-time admitted with a diagnosis of OCPD, with a sex ratio of 1.18 (males/females). Seventy-seven percent of the readmitted patients with a first-time diagnosis of OCD kept a diagnosis within the "emotional spectrum" at the last admission. About half kept OCD as a main diagnosis, whereas only 15% shifted to a severe psychiatric diagnosis such as schizophrenia or manic-depressive psychosis. Of the readmitted patients with OCPD, 13% later developed a diagnosis of manic-depressive psychosis.

Abstract
PURPOSE Recent reports have suggested that precolonoscopy bowel preparation is easier to tolerate if a small volume solution is used. Therefore, the aim of this study was to compare three oral solutions for colonoscopy to determine any changes in either patient compliance or cleansing ability. METHODS Four hundred fifty patients were prospectively randomized to receive either a standard 4-liter polyethylene glycol solution, a newer sulfate-free 4-liter polyethylene glycol solution, or a 90-ml oral sodium phosphate preparation. Before and after bowel preparation all patients were weighed, and serum electrolytes as well as phosphate, magnesium, calcium, and osmolarity were measured. In addition, a detailed questionnaire was used to assess side effects and patient satisfaction. Endoscopists blinded to the type and quantity of preparation used scored the type of residual stool and the percentage of bowel wall visualized for each segment of colon and for the overall examination. Nurses recorded all procedure times as well as the quantity of irrigation and aspiration. RESULTS Four hundred twenty-two age-matched and sex-matched patients completed all phases of the trial. There were no clinically significant changes in weight or in any biochemical parameters. There was, however, asymptomatic hyperphosphatemia in the sodium phosphate group (P < 0.01). The length of time to the cecum was similar for all three groups, with a higher volume of fluid suctioned for sodium phosphate (P < 0.01). Overall, endoscopists scored sodium phosphate as "excellent" or "good" in 90 percent vs. 70 percent and 73 percent after the polyethylene glycol or sulfate-free lavage, respectively (P < 0.01). Particulate or solid stool was found in all segments of the colon more frequently after both large volume preparations than after sodium phosphate (P < 0.05). There were no significant differences in the frequency or intensity of any of the 11 side effects questioned. Eighty-three percent of the patients who received the sodium phosphate preparation stated they would take this same preparation again, vs. only 19 percent and 33 percent for polyethylene glycol and the sulfate-free lavage, respectively (P < 0.01). CONCLUSION The smaller volume oral sodium phosphate was not associated with any clinically significant problem, caused no increase in the incidence of side effects, was preferred by patients, and was more effective in colonic cleansing. However, the hyperphosphatemia seen may limit its use in patients with impaired renal function.
