The aim of this study was to check the reliability of sonography in measuring small variations in quantities of subcutaneous and intra-abdominal fat. Twenty-six obese women (BMI 39 +/- 6) underwent a 15 day very low calorie diet. The study included, both before and after very low calorie diet, computed tomography measurements of total (AT), visceral (VAT) and subcutaneous (SAT) adipose tissue areas, visceral/subcutaneous area ratio (V/S), waist/hip circumference ratio measurements (W/H), and ultrasound measurements of abdominal subcutaneous skin-muscle thickness, intra-abdominal muscle-aorta thickness and intra-abdominal/subcutaneous thickness ratio. Weight reduction was from 101 +/- 17 to 95 +/- 16 kg (P less than 0.001). W/H dropped from 0.83 +/- 0.06 to 0.82 +/- 0.07 (n.s.). VAT dropped from 158 +/- 72 to 134 +/- 61 cm2 (P less than 0.005), SAT from 572 +/- 151 to 566 +/- 164 cm2 (n.s.) and V/S from 0.29 +/- 0.15 to 0.25 +/- 0.11 (P less than 0.01). Abdominal subcutaneous fat thickness decreased from 36 +/- 8 to 35 +/- 10 mm (n.s.), intra-abdominal thickness from 39 +/- 25 to 20 +/- 20 mm (P less than 0.001) and intra-abdominal/subcutaneous from 1.1 +/- 0.7 to 0.8 +/- 0.6 (P less than 0.005). VAT measurement accurately identified small intra-abdominal fat variations. W/H could not evaluate visceral fat loss, because of simultaneous decreases in waist and hip circumferences. Ultrasound was able to measure small reductions in intra-abdominal fat. 相似文献

Summary We have evaluated by means of immunocytochemistry the distribution of various cytoskeletal and contractile proteins (cytokeratins, vimentin, desmin and -smooth muscle actin) in 23 salivary or lacrimal gland primary tumours (15 pleomorphic adenomas and 8 carcinomas in pleomorphic adenoma), one third of which contained areas of normal gland. Normal epithelial luminal cells were stained by cytokeratin antibodies with a general specificity, while myoepithelial cells were selectively stained by a monoclonal antibody (SK2-27) reacting in immunoblots with cytokeratin polypeptides 14, 16 and 17, according to the classification of Moll et al. (1982) and by an antibody directed against -smooth muscle actin (Skalli et al. 1986). In pleomorphic adenomas, both epithelial and myoepithelial cells displayed typical topographic distributions; moreover, myoepithelial cells showed two distinct cytoskeletal phenotypes. These findings could account in part for the heterogeneity of aspects observed in this tumour. In carcinomas, malignant cells were always positive to cytokeratin antibodies with general specificity and myoepithelial cells were absent as judged by anticytokeratin SK2-27 and anti--smooth muscle actin immunostainings. However, interestingly, there was in all cases a strong positivity for -smooth muscle actin in stromal cells, similarly to what has previously been described for mammary carcinoma (Skalli et al. 1986). Our findings may be useful for the interpretation of the histogenesis of salivary and lacrimal tumour and stromal cells. 相似文献

Summary In a previous study, we observed an impairment of the theophylline-induced suppressive system in recent onset IDDM patients,
and demonstrated also a correlation with metabolic derangement. The aim of this study was to better investigate the relationship
between theophylline sensitivity (ThS) and blood glucose/plasma insulin levels in recent onset IDDM patients subjected to
preprogrammed variations by an insulin/glucose clamp with artificial pancreas. Eight patients were studied within 8 weeks
from the onset of IDDM. ThS was evaluated as the ability of theophylline to inhibit blastogenic response of peripheral blood
lymphocytes (PBL) to Concanavalin A (ConA), after 120 min preincubation of the cells. All patients were connected to an artificial
pancreas. Through i.v. continuous insulin infusion (0.02 U/kg/h) and/or i.v. continuous glucose and saline infusion, the following
experimental conditions, lasting at least 1h, were obtained: T1: relative euglycemia and normal insulinemia; T2: relative
euglycemia and hyperinsulinemia; T3: hyperglycemia and normal insulinemia; T4: hyperglycemia and hyperinsulinemia. ThS was
maintained in 6/8 patients at T1 and in 8/8 patients at T4. ThS was lost in 4/8 patients at T2 and T3. These data suggest
that the loss of ThS induced by hyperglycemia can be corrected by hyperinsulinemia, and that it is maintained when euglycemia
is accompained by hypoinsulinemia. It is lost when these two parameters lose their interrelationship. 相似文献

This study assessed technology-aided programs for helping two post-coma persons, who had emerged from a minimally conscious state and were affected by multiple disabilities, to (a) engage with leisure stimuli and request caregiver's procedures, (b) send out and listen to text messages for communication with distant partners, and (c) combine leisure engagement and procedure requests with text messaging within the same sessions. The program for leisure engagement and procedure requests relied on the use of a portable computer with commercial software, and a microswitch for the participants’ response. The program for text messaging communication involved the use of a portable computer, a GSM modem, a microswitch for the participants’ response, and specifically developed software. Results indicated that the participants were successful at each of the three stages of the study, thus providing relevant evidence concerning performance achievements only minimally documented. The implications of the findings in terms of technology and practical opportunities for post-coma persons with multiple disabilities are discussed. 相似文献

We report a child with post-surgical short bowel state who underwent bowel expansion followed by spiral intestinal lengthening and tailoring (SILT) at 10 months of age. Growth at 1-year follow-up is along the 15–25th centile on 82 % oral calories as normal diet and 18 % as parenteral nutrition, and he is passing 2–3 semisolid motions daily. SILT is a versatile technique for reconstructing dilated bowel towards improved propulsion and absorption, and has a role in the management of the short bowel state. 相似文献

The combined maternal administration of magnesium sulfate and aminophylline reduces intraventricular hemorrhage in very preterm neonates 总被引:3,自引:0,他引:3
Di Renzo GC Mignosa M Gerli S Burnelli L Luzi G Clerici G Taddei F Marinelli D Bragetti P Mezzetti D Della Torre B Fantauzzi A Lungarotti MS 《American journal of obstetrics and gynecology》2005,192(2):433-438
OBJECTIVE: To determine whether the adjunctive administration of aminophylline and magnesium sulfate to mothers at risk for preterm birth can reduce the rate of intraventricular hemorrhage in neonates born at less than 30 weeks of gestation. STUDY DESIGN: A prospective study was conducted to determine whether the rate of intraventricular hemorrhage was different in patients at risk for preterm delivery treated with ritodrine, magnesium sulfate, aminophylline, and corticosteroids (group A) versus patients treated with ritodrine and corticosteroids (group B). During the study period (January 1996 to December 2001), 125 patients enrolled in the study. Treatment was assigned by alternative allocation, and the study was designed to compare the rate of intraventricular hemorrhage in neonates born before the 30th week of gestation (primary outcome), 78 newborns in group A and 68 in group B. The proportion of neonates with intraventricular hemorrhage was calculated, and data were analyzed with Student t test, chi 2 , and logistic regression analysis. RESULTS: The frequency of severe respiratory distress syndrome needing surfactant replacement and high-pressure positive ventilation, patent ductus arteriosus, and retinopathy of prematurity was not different between the 2 groups. However, the rate of intraventricular hemorrhage was lower in neonates born before 30 weeks whose mothers received adjunctive aminophylline and magnesium sulphate (group A) than in the group that did not receive these 2 agents (group B). The overall frequency of intraventricular hemorrhage was 5.1% (4/78) versus 20.6% (14/68) ( P < .001), and the frequency of intraventricular hemorrhage grade 3-4 was 1.3% (1/78) versus 10.3 % (7/68; P < .001), respectively. CONCLUSION: Adjunctive maternal administration of aminophylline and magnesium sulfate was associated with a significant reduction in the rate of intraventricular hemorrhage in neonates born before 30 completed weeks. 相似文献

The first of these two studies assessed whether 11 participants with multiple disabilities of 5.3–18.2 (M = 10.7) years of age would succeed in combining a microswitch for accessing preferred environmental stimuli and a Voice Output Communication Aid (VOCA) for requesting social contact. The second study conducted a social validation assessment of the aforementioned microswitch–VOCA combination. Data showed that all participants learned to use the microswitch and the VOCA. Moreover, the 10 participants, who received a 1-month post-intervention check, largely maintained their responding. The social validation assessment indicated that the raters (i.e., 110 university psychology students) favored the combination of microswitch and VOCA over the microswitch or the VOCA alone, and hypothetical combinations of microswitches or VOCAs. 相似文献

The present two studies assessed the use of an optic sensor together with a scanning keyboard emulator to enable two young
adults with pervasive motor disabilities to click keyboard keys and, as a result, write. The optic sensor used for the participant
of Study 1 was a light-dependent resistor that the participant activated with his tongue. The optic sensor used for the participant
of Study II was a photoelectric device mounted on an eyeglasses’ frame that the participant activated by turning her eyes.
The results showed that the optic sensor together with a scanning keyboard emulator allowed the participants to write fairly
satisfactorily. Writing time per letter as well as numbers of words and letters written significantly improved during intervention
sessions as opposed to baseline sessions. Preference checks showed that both participants favored the optic sensor and related
tongue or eye response over the technology and responses available in baseline. Moreover, teacher trainees and psychology
students involved in social validation checks of the intervention program provided fairly positive ratings. 相似文献
