Abstract
Recent surveys of patients in New York and Cleveland, among other cities, indicate that there is substantial room for improvement in meeting patients' needs and preferences, particularly in the areas of emotional support, coordination of care, discharge preparation, and the involvement of family and friends. Hospitals are using a variety of techniques to improve patient care and organizational efficiency in this challenging environment. One prominent approach, reengineering, offers a means by which hospitals can integrate highly specialized departmental structures and functions by focusing on interdisciplinary teamwork and organizing the delivery of care around patients. Key elements of successful hospital reengineering efforts have included: - the involvement and commitment of senior management and other key stakeholders, particularly physicians, nurses, and union representatives; - investment in staff training and retraining, and the redesign of staff evaluation and compensation systems; - timely, unit-specific measures of patient satisfaction and the clinical quality of care; - consistent and frequent internal communication between staff and leadership; and - treatment that emphasizes communication among caregivers, patients, and their family members. Several basic issues need to be addressed if hospitals are to offer technically sophisticated medical care that is also responsive to their patients' personal needs, including: - variations among patients regarding the amount of information they want and need, and the amount of involvement they want in their care; - the means by which patients will get information about their medical care, and who will provide any additional support that may be needed by non-English-speaking or socioeconomically disadvantaged patients; and - the specific changes in medical practice and hospital processes that will promote the involvement of patients in their care.

Abstract
OBJECTIVE To investigate the biologic state of Chlamydia and its surface antigen expression in the synovial membranes of patients with Chlamydia-associated reactive arthritis/Reiter's syndrome (ReA/RS). METHODS Expression of chlamydial lipopolysaccharide (LPS), major outer membrane protein (MOMP), and elementary body (EB) antigens was studied by gold labeling immunoelectron microscopy on 6 synovial membrane and 2 synovial fluid (SF) pellet samples from 6 patients with Chlamydia-associated arthritis. The study findings were compared with 24-hour cultures of HeLa cells infected with Chlamydia trachomatis EB. RESULTS Persistent C trachomatis infection was found in all 6 synovial membrane samples from patients who had either early or chronic arthritis. The infection persisted despite antibiotic treatment, including a 1-month course of doxycycline therapy. Most persistent organisms were atypical reticulate bodies (RBs) found in both fibroblasts and macrophages. Specific, but weak, immunogold staining for all 3 antibodies was found on both intracellular RBs and extracellular EBs. In the SF samples, Chlamydia surface antigens were detected only in phagosomes containing degraded electron-dense materials. CONCLUSION The synovial membrane biopsies conducted in this study of Chlamydia-associated ReA/RS revealed atypical RBs with diminished MOMP and LPS expression. Such altered organisms may escape immune surveillance and contribute to disease chronicity; moreover, these organisms may be difficult to detect and treat in some ReA/RS patients.

Abstract
To understand better the mechanisms that lead to dorsoventrality in the lateral organs of plants, mutants at the phantastica (phan) locus of Antirrhinum majus have been identified and characterised. The leaves, bracts and petal lobes of phan mutants show varying degrees of reduction in dorsal tissues, indicating that phan is required for establishing dorsal cell identity. Each phan mutant produces a variety of different leaf morphologies, but has a characteristic and relatively constant floral phenotype. In several different forms of phan mutant leaves and petal lobes, novel boundaries between dorsal and ventral cell types form ectopic axes of growth, suggesting that phan-dependent dorsal cell identity is required for lateral growth of the wild-type leaf and petal lobe. Comparisons between the development of wild-type and mutant petals or leaves reveal that phan acts early in development of these lateral organs. The possible role of the phan gene in evolution of different leaf forms is discussed.

Abstract
Sex differences in period-amplitude-analysed (PAA) sleep EEG activity were evaluated in 20 symptomatic, unmedicated, unipolar, depressed outpatients. 19/20 PAA measures showed significant gender main effects or interactions. Overall, depressed females showed a higher incidence and amplitude of fast frequency, beta activity than males, particularly in the right hemisphere. Moreover, gender effects were also evident in sleep-stage-independent analysis of PAA measures. These findings are in striking contrast to normal controls for whom only slow-frequency activity differentiates males from females. These findings suggest that sex differences are stronger in depressed patients than those observed in normals and that these effects are more pronounced than age-related changes in sleep EEG activity.

Abstract
Urinary bladder outlet obstruction is a common medical problem. In order to understand the effects of outlet obstruction on bladder morphology, physiology, and pharmacology, several animal models of obstruction have been developed using a variety of species. Although there are marked differences in bladder size, capacity, compliance, physiology, and pharmacology among these species, responses to outlet obstruction have many common characteristics. This article will be separated into six areas: introduction, genetic factors mediating the response during the initial period of partial outlet obstruction and overdistension, cytostructural alterations that accompany compensated bladder function, alterations in innervation accompanying bladder hypertrophy secondary to partial outlet obstruction, alterations in calcium translocation during bladder hypertrophy, and metabolic factors involved in the response to partial outlet obstruction.

Abstract
Nonadrenergic imidazoline binding sites (imidazoline I2 sites) have been described to be colocated with monoamine oxidase (MAO) in the mitochondrial fraction of various cell types. In the present work, the authors considered whether this colocation could be associated with a functional interplay. In rat liver membranes, [3H]-idazoxan binding to I2 receptors was competed for by naphazoline and idazoxan, which also shared a high affinity for alpha-2 adrenoceptors (alpha-2 ARs). The chemicals 2-n-heptylimidazoline (S 15430), 1-methyl-5-n-heptylimidazole (S 15674), 2-benzofuran-2-yl-imidazoline (RX 801077) and 2-(1,3-benzodioxanyl)-2-imidazoline (RX 821029) exhibited higher affinity for I2 receptors than for alpha-2 ARs. The most selective agent was S 15430 with a 150-fold higher affinity for liver I2 receptors than for adipocyte alpha-2 ARs. Moreover, [3H]-idazoxan binding was also competed for by several MAO inhibitors (MAOI) that are not imidazoline or guanidinium derivatives such as tranylcypromine, harmaline, clorgiline and pargyline. Rat liver MAO activity was not only inhibited by MAOIs but also by some imidazoline derivatives: cirazoline, naphazoline, S 15674, RX 801077 and RX 821029. Idazoxan had no effect on MAO activity; it neither inhibited MAO nor prevented the inhibition induced by other imidazolines or MAOIs. This suggested that the ligand recognition site of I2 receptors was distinct from the MAOI target site. Furthermore, some imidazolines inhibited the activity of bovine plasma amine oxidase, an enzyme that does not possess the same cofactor as MAO and is insensitive to harmaline or pargyline.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The purpose of this study was to examine the effectiveness of brisk walking as a means of improving endurance fitness and influencing serum lipid and lipoprotein variables in previously sedentary women. Walkers (n = 10, mean (s.e.m.) age 47.3(2.0) years) followed a programme of brisk walking (mean(s.e.m.) speed 1.76(0.03) m s-1) for 12 weeks, after which the training stimulus was withdrawn. Controls (n = 10, mean(s.e.m.) age 41.6(1.2) years) maintained their habitual sedentary lifestyle throughout. Endurance fitness was determined using laboratory measures of responses to treadmill walking. Serum lipid and lipoprotein variables were determined in venous blood (12-h fasted). Body fatness was assessed by anthropometry and dietary practice using the 7-day weighed food intake technique. Measurements were repeated after 12 and 24 weeks. Brisk walking resulted in a decrease in heart rate and blood lactate concentration during exercise, while detraining was accompanied by a reversal of these changes. Changes in body mass and the ratio of circumferences at the waist and hip did not differ between groups but the sum of four skinfolds decreased with brisk walking and increased with detraining. High density lipoprotein (HDL) and HDL2 cholesterol increased with walking and decreased with detraining but no between group changes (analysis of variance, P < 0.05) were found in other lipid and lipoprotein variables. These findings suggest that regular brisk walking can improve endurance fitness and increase HDL cholesterol concentration in sedentary women.

Abstract
BACKGROUND Recent waterborne outbreaks have established Cryptosporidium as an emerging enteric pathogen, but foodborne transmission has rarely been reported. In October 1993, an outbreak of cryptosporidiosis occurred among students and staff attending a 1-day school agricultural fair in central Maine. DESIGN Environmental/laboratory investigation and cohort study. PARTICIPANTS Attendees of the fair and their household members. MAIN OUTCOME MEASURES Clinical or laboratory-confirmed cryptosporidiosis. Clinical cryptosporidiosis was defined as 3 days of either diarrhea (three loose stools in a 24-hour period) or vomiting. RESULTS Surveys were completed for 611 (81%) of the estimated 759 fair attendees. Among attendees who completed the survey, there were 160 (26%) primary cases. Cryptosporidium oocysts were detected in the stools of 50 (89%) of 56 primary and secondary case patients tested. The median incubation period was 6 days (range, 10 hours to 13 days); the median duration of illness was 6 days (range, 1 to 16 days). Eighty-four percent of primary case patients had diarrhea and 82% had vomiting. Persons drinking apple cider that was hand pressed in the afternoon were at increased risk for cryptosporidiosis (154 [54%] of 284 exposed vs six [2%] of 292 unexposed; relative risk, 26; 95% confidence interval, 12 to 59). Cryptosporidium oocysts were detected in the apple cider, on the cider press, and in the stool specimen of a calf on the farm that supplied the apples. The secondary household transmission rate was 15% (53/353). CONCLUSIONS This is the first large cryptosporidiosis outbreak in which foodborne transmission has been documented. It underscores the need for agricultural producers to take measures to avoid contamination of foodstuffs with infectious agents common to the farm environment.

Abstract
BACKGROUND This study evaluated whether a community psychiatric nurse (CPN) team providing a comprehensive aftercare service, using a case management approach, improves psychopathology and social functioning of the long-term mentally ill, and reduces hospital use compared with a generic CPN team. METHOD Patients suffering from severe and persistent mental health problems were randomised to intensive aftercare or generic care after referral to the CPN manager. Each group contained 41 patients who were assessed at baseline and at 6, 12 and 18 months by an independent research psychologist. Outcome measures included the GAS, PSE, SAS, patient and relatives' satisfaction, number of admissions, and length of stay. RESULTS No difference between the groups was found on any of the outcome measures, despite the much higher number of contacts of the intensive (n = 52) versus generic CPNs (n = 13) and the much greater range of interventions. CONCLUSIONS Intensive aftercare for people with persistent mental health problems was not found to be of greater benefit than generic CPN care. Many factors need to be considered for aftercare to be effective, including community resources, process of care, and staff training.

Abstract
Olive (oli) is a recessive nuclear mutation of Antirrhinum majus which reduces the level of chlorophyll pigmentation and affects the ultrastructure of chloroplasts. The oli-605 allele carries a Tam3 transposon insertion which has allowed the locus to be isolated. The oli gene encodes a large putative protein of 153 kDa which shows homology to the products of two bacterial genes necessary for tetrapyrrole-metal chelation during the synthesis of bacteriochlorophyll or cobyrinic acid. We therefore propose that the product of the oli gene is necessary for a key step of chlorophyll synthesis: the chelation of magnesium by protoporphyrin IX. Somatic reversion of the oli-605 allele produces chimeric plants which indicate that the oli gene functions cell-autonomously. Expression of oli is restricted to photosynthetic cells and repressed by light, suggesting that it may be involved in regulating the rate of chlorophyll synthesis in green tissues.

Abstract
The purpose of this study was to examine the influence of brisk walking on endurance fitness and the amount and distribution of body fat in previously sedentary women. Twenty eight women [mean age (SEM): 44.9 (1.5) years] followed the walking programme for 1 year, whilst 16 acted as controls [age 44.4 (2.3) years]. Changes in endurance fitness were evaluated by measuring the oxygen uptake (VO2) at a reference blood lactate concentration of 2 mmol.l-1. Two 1.61-km field tests of walking were completed, one at maximal speed and one at a "brisk" speed, as well as a 1.61-km walk on a motorised treadmill. The amount and distribution of body fat was determined by hydrostatic weighing and anthropometry and energy intake was evaluated using the 7-day weighed food intake method. Walkers completed an average of 157 min.week-1 of brisk walking over the year. The following were increased in walkers, relative to controls: brisk walking speed [walkers 1.73 (0.05) m.s-1 vs 1.88 (0.07) m.s-1; controls 1.69 (0.05) m.s-1 vs 1.70 (0.05) m.s-1 at baseline and 12 months respectively, P < 0.01], maximal walking speed and VO2 at 2 mmol.l-1. In addition, brisk walking reduced heart rate and blood lactate concentration during stepping as well as during standard, submaximal treadmill walking. It did not modify either the amount or the distribution of body fat, despite an unchanged energy intake.

Abstract
The acute effects of low-intensity exercise on plasma lipids were assessed in 22 healthy, normolipidaemic volunteers [mean age (SEM) 21.1 (0.2) years] of whom 11 were untrained and 11 endurance trained. Each subject walked for 2 h on a treadmill at a speed selected to elicit 30% [29.8 (3.9)%] of his or her maximal oxygen uptake. All subjects consumed a similar diet, i.e. 48% of energy from carbohydrate, for 2 days prior to the test. Pre-exercise, high-density lipoprotein (HDL) cholesterol concentration was higher in the trained group than in the untrained group [0.88 (0.06) mmol.l-1 vs 0.73 (0.09) mmol.l-1, P less than 0.05]. The walk elicited an increase in blood lactate concentration (P less than 0.01) but glucose homeostasis was well maintained by both groups. After 2 h of walking total cholesterol had increased by 13 (0.6)% (P less than 0.05). HDL cholesterol concentration increased by 17 (1.6)%, so that the ratio of total to HDL cholesterol was lower after the walk than pre-exercise (P less than 0.05). In the endurance-trained group HDL cholesterol concentration increased progressively, being 7.9 (2.4)% higher after 1 h and 19.7 (1.6)% higher after 2 h. A different response was evident in the untrained group where a rise after the 1st h [25.1 (2.3)%] was followed by a decrease towards pre-exercise values. These results show that one prolonged bout of low-intensity exercise modifies lipoprotein metabolism and hold out the interesting possibility that this response may differ in trained and untrained individuals.

Abstract
To investigate preliminary reports that benzodiazepine-induced sedation may be reversed by thyrotropin-releasing hormone (TRH), we examined the effect of TRH or saline placebo on two variables which are sensitive to benzodiazepine agonists: changes in sedation and saccadic eye movements. Lorazepam 10 micrograms/kg i.v. increased self-ratings of sedation and reduced self-ratings of alertness and these changes were almost completely reversed by TRH. In contrast the slowing of saccadic eye movements by lorazepam was not reversed by TRH. The effects of TRH do not appear to be due to a direct antagonism at the benzodiazepine receptor, since flumazenil reverses changes in both variables. Moreover ligand binding studies reveal that TRH has very low affinity at this receptor. These clinical data provide the first demonstration that it is possible to distinguish between the effects of benzodiazepines on saccadic eye movements and psychological self-ratings.

Abstract
Interleukin (IL)-1 is an early mediator of host response to inflammation, although its contribution to individual components of the acute phase reaction is still unclear. To evaluate how the hemodynamic, metabolic, and hormonal responses to sublethal endotoxemia compare with IL-1 administration, baboons received intravenously either lipopolysaccharide (LPS) or 0.1, 10, or 100 micrograms/kg IL-1 alpha. LPS induced an early tachycardia and a fall in mean arterial pressure, as well as lacticacidemia and hypoaminoacidemia. Similar hemodynamic and metabolic changes were seen with 10 or 100 micrograms/kg of IL-1 alpha. An increase in adrenocorticotropic hormone and fall in serum iron were induced by IL-1 alpha but not by LPS. Plasma tumor necrosis factor-alpha (TNF-alpha) was not measurable after IL-1 alpha administration, whereas LPS induced a monophasic TNF-alpha response. IL-6 levels were significantly greater after LPS than IL-1 alpha administration. Histopathological lesions, similar in LPS- and 100 micrograms/kg IL-1 alpha-treated groups, were present only in the adrenal cortex. We conclude that many, but not all, of the effects of sublethal endotoxemia can be replicated by IL-1 alpha administration, and these responses are dose dependent.

Abstract
The amount and type of exercise needed to maintain or increase bone density in women is unclear. The purpose of the present study was to examine the influence of brisk walking on broadband ultrasonic attenuation (BUA) values for the calcaneus in formerly sedentary women aged 30-61 years (mean 44). Twenty-five women followed the program of brisk walking for 1 year and 15 acted as controls. The walkers completed an average (SEM) of 159 (46) minutes/week of brisk walking at a speed of 1.72 (0.05) meters/second, i.e., about 16-18 km/week. Broadband ultrasonic attenuation was determined at baseline and after 1 year. Analysis of variance showed that values were increased (P less than 0.05) for the walkers relative to controls [walkers 103.3 (4.9) versus 116.1 (3.8) dB/MHz; controls 103.6 (5.5) versus 99.6 (5.4) dB/MHz]. We conclude that, in formerly sedentary women, a modest program of a widely acceptable form of exercise, brisk walking, can provoke an increase in this sensitive index of bone condition.

Abstract
The cases of forty patients who were operated on consecutively for palsy of the posterior interosseous nerve were analyzed. The injury was iatrogenic in sixteen patients, traumatic in fifteen, and nontraumatic in nine. Persistent paralysis (partial or complete) was the only indication for operation. Operative neurolysis was done in twenty-three patients; interfascicular nerve-grafting, in twelve; internal neurolysis, in one; and tendon transfer, in four. An excellent or good functional result was documented for all but three patients, of whom two had had neurolysis and one, nerve-grafting.

Abstract
Nurses employed in acute care hospitals frequently encounter patients who require a pressure-relieving device. It is often difficult for nurses to decide which support surface should be used to best meet a patient's need for a pressure-reducing device because of the multiplicity of products available. One of the variables studied was found not to statistically influence the effectiveness of the various pressure-relieving devices. Body build is not a consideration when determining which support surface is effective in a healthy population of subjects. The two air-flotation low air-loss beds would be defined as effective pressure-relieving devices. The interface pressure readings vary from individual to individual on various bony prominences. The population studied was that of healthy volunteers. Healthy subjects have an increased fat pad in their sacral area compared with the critically ill patient. The heel had the highest interface pressure of the five that were studied. This is a bony prominence that requires additional attention if skin integrity is to be maintained.

Abstract
The influence on protein accretion and whole-body protein turnover of changing dietary protein quality while maintaining constant energy intake was studied by varying the degree of lysine supplementation of a lysine-deficient barley-based diet given to growing pigs. Measurements of nitrogen metabolism and whole-body protein turnover, using both classical and 15N end-product methods following a single dose of [15N]glycine, were made in 49-kg male pigs given diets containing 109 g lysine-deficient protein/kg supplemented to make them (1) 'deficient', (2) 'adequate' and (3) 'in excess' with respect to lysine. The 15N dose and protein intake values used to calculate amino N flux from the cumulative urinary excretion of 15N in urea and ammonia were corrected respectively for apparent digestibilities of [15N]glycine and total N determined in a separate experiment in pigs fitted with simple ileal cannulas. N retention and biological value were significantly increased by lysine supplementation of the deficient diet to the 'adequate' level, but were not further increased by the higher level of supplementation. Rates of growth paralleled these changes. The poorer biological value of the unsupplemented diet 1 was shown also in a significantly higher excretion of urea N compared with diets 2 and 3. N digestibility was not markedly influenced by the level of lysine supplementation. Both whole-body protein synthesis and degradation increased markedly on 'adequate' supplementation of the diet with lysine, but did not increase further with an excess of lysine. It is concluded that the increase in protein accretion rate observed on supplementation of the diet with lysine was due to a greater increase in the rate of protein synthesis than of degradation, rather than a decrease in degradation rate.

Abstract
Sixteen consecutive patients entered in a prospective study of non-neurogenic soft tissue tumours had lesions in the axilla. Delayed diagnosis and inappropriate biopsy prior to referral to a surgical oncologist were frequent findings. Sarcoma and fibromatosis were diagnosed in 14 cases, and the approaches used for these two diseases were fundamentally different. The functional outcome with limb salvage surgery in these patients is presented.

Abstract
In situ hybridization histochemistry was used to identify neurons in rat dorsal root ganglia that contained mRNAs encoding beta-preprotachykinin and preprosomatostatin. The distribution of these neurons was compared with the distribution of neurons containing tachykinins or somatostatin, identified using immunocytochemical techniques. Neurons labelled for beta-preprotachykinin mRNA constituted 20% of the total neuronal population and belonged to the small cell class. Neurons labelled for preprosomatostatin mRNA with either RNA or DNA hybridization probes constituted approximately 10% of the total cells and comprised a small cell group that differed in average size from the beta-preprotachykinin labelled population. The distribution of cells containing tachykinin- or somatostatin-like immunoreactive material was identical to the distribution of cells containing the respective mRNAs and, in addition, individual somata in adjacent sections contained both the mRNA precursor and the peptide. These results suggest that for these neuropeptides the sensitivity of the two methods is equivalent and the respective mRNAs and peptides are co-localized in the same neurons.

Abstract
The vast majority of nuclease activity in yeast mitochondria is due to a single polypeptide with an apparent molecular weight of 38,000. The enzyme is located in the mitochondrial inner membrane and requires non-ionic detergents for solubilization and activity. A combination of heparin-agarose and Cibacron blue-agarose chromatography was employed to purify the nuclease to approximately 90% homogeneity. The purified enzyme shows multiple activities: 1) RNase activity on single-stranded, but not double-stranded RNA, 2) endonuclease activity on single- and double-stranded DNA, and 3) a 5'-exonuclease activity on double-stranded DNA. Digestion products with DNA contain 5'-phosphorylated termini. Antibody raised against an analogous enzyme purified from Neurospora crassa (Chow, T. Y. K., and Fraser, M. (1983) J. Biol. Chem. 258, 12010-12018) inhibits and immunoprecipitates the yeast enzyme. This antibody inhibits 90-95% of all nuclease activity present in solubilized mitochondria, indicating that the purified nuclease accounts for the bulk of mitochondrial nucleolytic activity. Analysis of a mutant strain in which the gene for the nuclease has been disrupted supports this conclusion and shows that all detectable DNase activity and most nonspecific RNase activity in the mitochondria is due to this single enzyme.

Abstract
High resolution CT of the parasellar region was carried out in 50 patients studied for suspected pituitary microadenoma, but who showed normal pituitary gland or microadenoma on CT. This control group of patients all showed an ellipsoid low-density area in the posterior parasellar region. Knowledge of the gross anatomy and correlation with metrizamide cisternography suggest that the low density region represents Meckel's cave, rather than just the trigeminal ganglion alone. Though there is considerable variation in the size of Meckel's cave in different patients as well as the two sides of the same patient, the rather constant ellipsoid configuration of the cave in normal subjects will aid in diagnosing small pathological lesions, thereby obviating more invasive cisternography via the transovale or lumbar route. Patients with "idiopathic" tic douloureux do not show a Meckel's cave significantly different from the control group.

Abstract
The most abundant amine in acid hydrolysates of human skin, eluting in the crosslink region of a reversed-phase HPLC chromatogram, has the same retention time as pyridinoline standard. This amine is not pyridinoline, since it is a weak fluorophore and its U/V spectrum does not agree with that of pyridinoline. The unknown amine was isolated and characterized by fast atom bombardment mass spectrometry and its structure is consistent with a deoxy-analogue of pyridinoline. It may be a crosslink component of some biological importance, since it is not detectable in skin from a patient with Marfan's Syndrome.

Abstract
In brief: Athletes aggravate acne by coming in contact with other competitors, rubbing against sports equipment and tight clothing, and sweating excessively. Another factor is the psychological stress involved in competition. However, these aggravations are part of sports, so it is impossible to avoid them. Athletes should wear clean, dry, loose-fitting, absorbent, cotton clothing and change wet clothing as soon as possible. They should work out with minimal clothing and equipment in a cool, well-ventilated environment whenever practical. Systemic and topical antimicrobial drugs are the most effective, dependable form of acne treatment, although some side effects exist. If these drugs do not control a patient's acne, he or she should be referred to a dermatologist.

Abstract
There is considerable evidence that somatostatin is released from nerve terminals throughout the central nervous system in response to presynaptic stimulation, thus suggesting a neuromodulator role for the peptide. We here report the partial characterization of immunoreactive somatostatin released from rat nervous system in vitro (hypothalamus, spinal cord and hypothalamic, cortical, thalamic and striatal synaptosomes). Serial dilutions of released somatostatin immunoreactivity showed parallelism with dilutions of synthetic somatostatin standard. Somatostatin immunoreactivity released from all tissue areas coeluted with synthetic tetradecapeptide on Sephadex G-25 (fine grade) gel chromatography; more than 85% of this immunoreactivity bound to Sepharose-anti-somatostatin-serum immunoaffinity columns. In addition, immunoreactive material released from hypothalamus, spinal cord and hypothalamic and cortical synaptosomes inhibited somatotropin (growth hormone, 'STH', 'GH') release from perifused anterior pituitary in a dose-related manner, indicating biological similarity to synthetic somatostatin.

Abstract
Fifty smokers and fifty non-smokers were administered the MMPI's Manifest Anxiety Scale (MAS). Mean MAS scores for smokers were significantly higher than those of non-smokers. Item analysis revealed that smokers obtained higher scores than non-smokers on significantly more items in which anxiety is manifested by a physical symptom rather than a psychological symptom. It is possible that physical stimulation by nicotine may contribute to a more ready arousal to anxiety in smokers.

Abstract
The nerve allograft response between closely and distantly related inbred strains of rats was investigated. Lewis rats (RTl1) and Fischer rats (RTl1) have only minor histocompatibility differences, whereas Buffalo rats (RTlb) and ACI rats (RTla) differ from Lewis rats at the major histocompatibility locus. Lewis rats served as the recipient animals; the other three strains of rats provided donor nerves. The 51 Cr release cytotoxicity assay was used to asses antigen recognition. The results showed sensitization with ACI and Buffalo nerves as early as Day 8. When the donor and recipient were matched (Lewis/Fischer), sensitization occurred very late (Day 80). By contrast, with skin allografts, sensitization occurred early with all strains (Day 10), even when the animals differed only at the minor histocompatibility loci. Histological changes were similar in all three donor strains (Fischer, Buffalo, ACI). The strain of origin of the nerve could not be deduced by an unbiased examiner.
