Evaluation Of The Quality Of Life Levels Of Undergraduate And Associate Degree Students Studying In Health Departments

@#Quality of life is at the forefront of the goals that all societies aim to achieve today. This is the main reason why measuring quality of life is a routine procedure in many studies. This study was carried out by undergraduate and associate degree students of health sciences; the aim of this study was to evaluate and compare the quality of life. The research was carried out on a total of 200 undergraduate and associate degree students studying in the health sciences departments of the same university in a one-year period. In order to obtain the demographic information of the students; the personal data collection form created by the researchers and the World Health Organization Quality of Life Scale-Short Form (WHOQOL-Bref) were applied by one to one interview technique. The voluntariness of the participants was taken as a basis in filling out the questionnaires. SPSS-22 program was used to evaluate the data in our study. By making descriptive statistics, two independent groups were compared between the groups. The mean age of the associate degree students participating in our study was 20.6 ± 1.26, and the undergraduate students were 20.8 ± 3.07. When the last question, the 27th environmental question, is included in the WHOQOL-Bref scale, which consists of four sub-parameters, the name of the scale is named WHOQOL-Bref-TR. In our study, which we evaluated with WHOQOL-Bref-TR, the scores of undergraduate students in the "psychological field" sub-category were found to be significantly higher (p>0.05) than associate degree students in comparisons made based on education level. In the comparison made according to genders, the difference in general health, psychological, and environmental dimensions was not significant (p>0.05). In conclusion; in all comparisons, the level of quality of life and problem solving abilities do not differ depending on gender. As the education level increases; the psychological state, which has an effect on the quality of life, increases positively. With the data obtained, suggestions were made to curriculum arrangements and university administrations in order to increase the quality of life of young adults.

Comparison Of The Problem Solving Skills Levels Of Health Department Students Educed At Undergraduate And Associate Degree Level

@#Our study was conducted with the aim of comparing the parameters such as personal control, self-care level, academic achievement and family characteristics that affect the problem solving skill levels of undergraduate and associate degree students studying in health departments. Our research is cross-sectional; those who study at the same university in one year; It was carried out on 200 students, 100 of whom are at undergraduate level and 100 of whom are at associate degree level. In order to obtain the demographic information of the students; The personal data collection form created by the researchers was used and the "Problem Solving Inventory (PSI)" was used to determine problem solving skill levels.Data collection forms and questionnaires were applied with one-on-one interview technique. The voluntariness of the participants was taken as a basis in filling out the questionnaires. After the descriptive statistics (frequency, mean, standard deviation) of the socio-demographic data obtained and the scale scores and sub-dimension scores were made, two independent groups were compared by looking at their normal distribution conformity. The mean age of associate degree students participating in our study was 20.6 ± 1.26, and 20.8 ± 3.07 for undergraduate students. In comparisons made with PSI, which consists of three different sub-parameters, associate degree students are significantly more successful than undergraduate students in terms of "approach-avoidance", "personal control" and "problem solving questionnaire total score" (p>0.05). No difference was found in terms of "confidence in problem solving ability" sub-dimension. In the comparison of the Problem Solving Questionnaire by gender; no significant difference was found in sub-dimensions and total score(p>0.05). As a result; In all comparisons, problem solving abilities do not differ according to gender. The problem solving skill level was found to be moderate for both genders. As the education level increases; The psychological state, which has an effect on the quality of life, increases in the negative direction. In terms of problem solving abilities, a negative correlation was found with education level in all sub-categories.

Predicting clinical outcomes in neuroblastoma with genomic data integration.

BACKGROUND: Neuroblastoma is a heterogeneous disease with diverse clinical outcomes. Current risk group models require improvement as patients within the same risk group can still show variable prognosis. Recently collected genome-wide datasets provide opportunities to infer neuroblastoma subtypes in a more unified way. Within this context, data integration is critical as different molecular characteristics can contain complementary signals. To this end, we utilized the genomic datasets available for the SEQC cohort patients to develop supervised and unsupervised models that can predict disease prognosis. RESULTS: Our supervised model trained on the SEQC cohort can accurately predict overall survival and event-free survival profiles of patients in two independent cohorts. We also performed extensive experiments to assess the prediction accuracy of high risk patients and patients without MYCN amplification. Our results from this part suggest that clinical endpoints can be predicted accurately across multiple cohorts. To explore the data in an unsupervised manner, we used an integrative clustering strategy named multi-view kernel k-means (MVKKM) that can effectively integrate multiple high-dimensional datasets with varying weights. We observed that integrating different gene expression datasets results in a better patient stratification compared to using these datasets individually. Also, our identified subgroups provide a better Cox regression model fit compared to the existing risk group definitions. CONCLUSION: Altogether, our results indicate that integration of multiple genomic characterizations enables the discovery of subtypes that improve over existing definitions of risk groups. Effective prediction of survival times will have a direct impact on choosing the right therapies for patients. REVIEWERS: This article was reviewed by Susmita Datta, Wenzhong Xiao and Ziv Shkedy.

Diagnostic performance of real-time strain sonoelastography in BI-RADS 4 and 5 breast masses.

PURPOSE: The purpose of this study was to evaluate the diagnostic performance of sonoelastography by using real-time strain ratio and qualitative 5-stage elasticity score in breast lesions for which ultrasonographic evaluation suggested malignancy (BI-RADS 4 and 5 lesions). MATERIALS AND METHODS: From January 2012 to October 2012, 168 solid breast lesions were investigated using sonoelastography. The strain ratios and the elasticity scores were calculated. Final diagnosis was made by histopathological analysis. Areas under the curve and cut-off points were used to assess diagnostic performance of sonoelastography. The sensitivity, and specificity of these two imaging tests were compared using McNemar test. RESULTS: The strain ratios of malignant lesions (mean value=9.3) and benign lesions (mean value=3.75) were significantly different (P<0.00001). Using a cut-off value of 4.79, strain ratio had 78.8% sensitivity, 78.3% specificity, 86.7% positive predictive value (PPV) and 67% negative predictive value (NPV). Using a 5-stage elasticity score system, a 83.3% sensitivity, 74.6% specificity, 85.7% PPV and 71.0% NPV were obtained. CONCLUSION: Our study indicates that sonoelastography has good clinical value to discriminate between benign and malignant breast lesions. There are no differences in terms of diagnostic performance in differentiating malignant from benign lesions when strain ratio or color scoring are used alone. However the diagnostic performance is increased when strain ratio and color scoring evaluations are used in combination.

Refractive errors and refractive development in premature infants.

PURPOSE: To examine refractive errors and refractive development in premature infants. METHODS: Premature infants in the retinopathy of prematurity (ROP) screening program were recruited and examined longitudinally between 28 and 58 weeks postmenstrual age. For performing cycloplegic retinoscopy, 1% tropicamide was administered, two drops with a 10-minute interval, in order to paralyze accommodation and to achieve cycloplegia. Birth weight, gestational age, gender and acute ROP disease were recorded. The relationship between spherical equivalent, astigmatism and postmenstrual age was evaluated. RESULTS: A total of 798 readings were obtained from 258 infants (131 females, 127 males) between 28 and 58 weeks postmenstrual age. The median number of examinations was 3 (minimum 1, maximum 7). In the comparisons of birth weight, gestational age, spherical equivalent and astigmatism between genders, there were no statistically significant differences (P>0.05). Gestational age (regression analysis, r(2)=0.30, P<0.01) and birth weight (regression analysis, r(2)=0.22, P<0.01) had a significant effect on refractive error development. Preterm babies with lower birth weight and those born more prematurely had lower spherical equivalent. The spherical equivalent of the eyes correlated significantly with the postmenstrual age of the infants (r=0.512, P<0.01). CONCLUSIONS: Infants with low gestational age and low birth weight also had low spherical equivalent. Moreover, spherical equivalent correlated with increasing postmenstrual age. However, astigmatism did not correlate with postmenstrual age and did not associate with gestational age or birth weight.

Thrombocytopenia in pregnancy: do the time of diagnosis and delivery route affect pregnancy outcome in parturients with idiopathic thrombocytopenic purpura?

The objective of this study was to investigate the determining effects of diagnosis time on pregnancy outcomes in a population of pregnant women with idiopathic thrombocytopenic purpura (ITP). Records of all the pregnant women with thrombocytopenia were evaluated. Those with a confirmed diagnosis of ITP were included in the study. Main outcome measures were antenatal thrombocyte count, postpartum haemorrhage rate, and route of delivery. Foetal outcomes such as foetal thrombocyte count, haemorrhage, and birth weight were also reported as secondary outcome measures. Time of diagnosis either antenatal or preconception did not significantly alter the investigated parameters. Delivery route had no impact on complication rates. Time of diagnosis also did not affect treatment modality. ITP is rare disorder accounting for less than 5 % of all pregnant thrombocytopenias. Time of diagnosis does not affect maternal-foetal outcomes or treatment modality unless diagnosis is made during labour. Compared to gestational thrombocytopenia, treatment rates may differ but treatment modalities remain the same and the effort put into making the differential should be weighed against maternal stress factors for lengthy laboratory evaluation as long as the thrombocytopenia is of pure nature without any systemic involvement.

Microphthalmia in a case of Edward syndrome.

AIM: To present an infant of trisomy 18 (Edwards Syndrome) with unilateral microphthalmia. METHODS: A female infant who was born at 41 weeks of gestation had been diagnosed with Edwards Syndrome (ES). On ophthalmic examination, microphthalmia, microcornea, optic disc coloboma, and persistent hyaloid artery were determined in the left eye. In addition, abnormalities in the ears, hands, feet, and cardiovascular system were present. DISCUSSION: With this case report, we aimed to highlight the relationship between ocular disgenesis and chromosomal disorders and the importance of prenatal testing and genetic counseling for parents.

Diagnosing early onset dementia and then what? A frustrating system of aftercare resources.

Recent studies indicate that the prevalence of early onset dementia (EOD) is more common than it was once presumed. As such, and considering the substantial challenges EOD presents to the patient, caregivers, and health care providers, this study sought to investigate the mechanism of care delivered to these patients. A medical record chart review was conducted for 85 patients attending a memory disorder unit who initially presented to rule out EOD as a working diagnosis. The results suggest that while the majority of these patients received an extensive work-up and were heavily medicated, they remained at home, where they lacked adequate age-related services and could not be placed, despite the crippling caregiver burden. This manuscript is a platform to discuss our current system limitations in the care of these patients with an eye on new opportunities for this challenging group.

The importance of staphylococci and threshold value of somatic cell count for diagnosis of sub-clinical mastitis in Pirlak sheep at mid-lactation.

This study investigated the bacterial agents causing sub-clinical mastitis and the mean somatic cell counts (SCC) of milk in Pirlak sheep at mid-lactation. The percentage of infected udder halves was 11.4% (53/464). The most frequently isolated species were coagulase-negative staphylococci (CNS) (64.2%), followed by Staphylococcus aureus (24.5%) and Escherichia coli (11.3%). Among the CNS, the most common species was Staphylococcus epidermidis (38.2%). The other species isolated from milk samples were Staphylococcus xylosus (17.7%), Staphylococcus chromogenes (14.7%), Staphylococcus simulans (8.8%) and Staphylococcus hyicus (8.8%). The mean SCC for culture positive and negative samples was 1742×10(3) and 161×10(3) cells/ml, respectively. A significant difference (p<0.05) was determined between with and without microbial growth groups in terms of the SCC values. Threshold limit for SCC was 374×10(3) cells/ml for Pirlak sheep. In conclusion, it was considered that SCC is an important predictor of sub-clinical mastitis in Pirlak sheep. This is the first study to describe the bacterial agents causing sub-clinical mastitis and threshold limit for SCC in Pirlak sheep in Turkey.

A new ocular trauma score in pediatric penetrating eye injuries.

PURPOSE: To assess the prognostic value of a new ocular trauma score (OTS) in pediatric penetrating injuries. METHODS: Children ≤ 15 years of age that presented to the emergency room with penetrating eye injuries between April 2007 and August 2008 were evaluated prospectively. All patients were reviewed on the basis of age, gender, time of injury and how it happened, time of admission, time of surgery, type of penetrating injury, initial and final visual acuity (VA), and concomitant eye pathology. Injuries were classified based on a new OTS, and we assessed the relationship with final VA and the new OTS. RESULTS: In total, 30 eyes in 29 patients (41.38% female, 58.62% male) with a mean age of 6.83 ± 4.00 years (range: 1-15 years) were included in the study. Initial VA, which was evaluated in 22 patients, was as follows: no light perception (NLP) in 2 (9.09%) patients, light perception (LP) to hand motion (HM) in 8 (36.36%) patients, counting fingers in 6 (27.27%) patients, 0.1-0.5 in 4 (18.18%) patients, and ≥ 0.6 in 2 (9.09%) patients. Final VA, which was evaluated in 27 patients, was as follows: NLP in 3 (11.11%) patients, LP to HM in 3 (11.11%) patients, counting fingers in 2 (7.41%) patients, 0.1-0.5 in 11 (40.74%) patients, and ≥ 0.6 in 8 (29.63%) patients. The relationship between initial VA and final VA was statistically significant (P < 0.001). CONCLUSIONS: The new OTS calculated at initial examination may be of prognostic value in children with penetrating eye injuries.

Topical cyclosporine A for the dry eye findings of thyroid orbitopathy patients.

PURPOSE: To determine the beneficial effect of topically administered Cyclosporine A (CsA) for the dry eye findings of thyroid orbitopathy patients. PATIENTS AND METHODS: This prospective pilot study included 73 eyes of 42 patients with thyroid orbitopathy who had documented dry eye findings. Patients were randomly assigned into two groups: in group 1 (48 eyes), patients received topical artificial tear-drop treatment. In group 2 (25 eyes), patients received topical CsA and artificial tear-drop treatment. During a mean follow-up of 6 months, change in Schirmer's test with aneasthesia, tear break-up-time (BUT) and impression cytology results were analyzed and were compared between groups. RESULTS: The two groups were age (P=0.449) and gender (P=0.942) matched. The Schirmer's test (P=0.441), tear BUT (P=0.718) and impression score (P=0.103) were also similar before the treatment in both groups. In group 1, all three parameters improved significantly with treatment (P<0.001 for all). In group 2, Schirmer's test (P=0.001) and tear BUT (P<0.001) improved, but the impression score (P=0.175) did not change significantly after treatment. The percentage of patients with improved tear BUT (P=0.04) and improved impression score (P<0.001) were higher in group 1. At the end of follow-up, group 1 patients had better Schirmer's test (P=0.004), tear BUT (P=0.021) and impression scores (P<0.001), than group 2 patients. CONCLUSIONS: The combined CsA use with artificial tear drops is not more advantageous than the use of artificial tear drops alone, for the dry eye findings of thyroid orbitopathy patients.

Effect of diabetes mellitus on female sexual function and risk factors.

The study was conducted to investigate the effect of diabetes mellitus upon female sexual function, and to detect possible risk factors that might predict sexual dysfunction. The study consisted of 127 married women: 21 women with type 1 diabetes, 50 women with type 2 diabetes and 56 healthy women as a control. Female sexual functions were evaluated with a questionnaire to assess sexual desire, arousal, lubrication, orgasm, satisfaction and pain. The prevalence of sexual dysfunction was 71% in the type 1 diabetic group, 42% in the type 2 diabetic group and 37% in the control subjects. The scores for sexual desire, arousal and lubrication were significantly lower in the type 1 diabetes group than in the control subjects (p < 0.05). The scores of orgasm, satisfaction, dyspareunia and total sexual function were slightly lower in the type 1 diabetic group than in the other groups. No factor predicted sexual dysfunction in the diabetic women while further age, poor education, absence of occupation and menopause predicted sexual dysfunction in the control subjects. The prevalence of sexual dysfunction was significantly higher in the type 1 diabetic women than in the type 2 diabetics and control subjects. However, no risk factors that might cause sexual dysfunction could be predicted in diabetic women.

Interferon alpha-2b may impair testicular histology including spermatogenesis in a rat model.

Interferon-alpha has been used in various diseases at the reproductive ages. However, the effect of interferon-alpha on testicular histology has not been studied in literature. The aim of this study was to investigate the effects of interferon alpha-2B on testicular histology including spermatogenesis in a rat model. Seventeen adult male Wistar albino rats were divided into 3 groups: Six rats received 7.500 units (5 MIU/m2) of interferon alpha-2B (Intron), considered clinical treatment dose range. Six rats received 30.000 units (20 MIU/m2) of interferon alpha-2B (Intron), considered high treatment dose. Five rats served as a control group receiving 0.5 mL of saline injection. All injections were done intraperitoneally 3 times weekly for 3 weeks under inhalation anesthesia. All rats underwent bilateral orchiectomy 30 days after the experiment. Histological examination included the mean seminiferous tubular diameter (STD), germinal epithelial cell thickness (GECT), and testicular biopsy score (TBS). The mean STD was significantly lower in the low-dose interferon and high-dose interferon groups than in the control group (p = 0.008 and p = 0.004, respectively). The mean GECT was significantly lower in the low-dose interferon and high-dose interferon groups than in the control group (p = 0.008 and p = 0.004, respectively). The mean TBS was significantly lower in the low-dose interferon group (p = 0.05) and the high-dose interferon group (p = 0.01) than in the control group. The decreases in the mean values of the STD, GECT and TBS were not related to the interferon dose. Interferon alpha-2B may impair testicular histology even in clinical widely used treatment dose. Therefore, men at the reproductive ages should be fully informed for the use of interferon-alpha in the treatment of various diseases.

Is routine hormonal measurement necessary in initial evaluation of men with erectile dysfunction?

To prospectively compare serum hormone levels and the incidence of hormonal pathologies between men with and without erectile dysfunction, and investigate risk factors that might predict hormonal pathologies in men complaining of erectile dysfunction. The study included 262 men with erectile dysfunction and 53 healthy men with no erectile dysfunction as a control group. All men enrolled in the study were evaluated with a detailed history, physical examination, international index of erectile function (IIEF-5), and serum hormone measurement. Hypotestosteronemia was considered as serum total testosterone value of < 3 ng/mL, and hyperprolactinemia was considered as serum prolactin level of > 18 ng/mL. Serum hormone levels and the incidence of hormonal abnormalities were compared between the two groups. In addition, risk factors for hormonal abnormalities were investigated. There were no significant differences in the mean serum FSH (p = 0.212), LH (p = 0.623), testosterone (p = 0.332) and prolactin values (p = 0.351) between the men with and without erectile dysfunction. Hypotestosteronemia was detected in 29 (11%) of the erectile dysfunction group and in 2 (3.7%) of the control group, revealing no significant difference (p = 0.104). Hyperprolactinemia was detected in 25 (9.5%) of the erectile dysfunction group and in 2 (3.7%) of the control group, revealing no significant difference (p = 0.171). To investigate risk factors that might predict hormonal pathologies, there were no significant differences in the patient age, duration of the sexual dysfunction, smoking history and duration, the presence of chronic disease and the type of erectile dysfunction. Our findings suggest that hormonal measurement should not be routinely performed in the initial evaluation of men presenting with erectile dysfunction, and may be necessary based only on the findings obtained with a careful history and physical examination.

Three words three shapes: A clinical test of memory.

Three Words - Three Shapes was designed as an easy "bedside" test for elderly patients that assesses verbal and nonverbal memory within the same modality. In the present study, it was administered to patients with probable Alzheimer's disease (PRAD), a control group of non-demented older subjects (NC) and a group of patients with Korsakoff's amnesia (KA). Incidental recall and several other measures of learning, retention and recognition differentiated control from PRAD and KA subjects. PRAD and KA subjects' performance was similar, but there were some material-specific interactions. This test is relatively easy and some of the derived measures could prove useful in staging amnesia progression beyond the earliest stages of PRAD when more difficult tests yield floor effects.

The central role of the prefrontal cortex in directing attention to novel events.

The physiological basis for the striking decrease of attention to novel events following frontal lobe injury is poorly understood. In this study, event-related potentials (ERPs) were recorded from patients with frontal lobe damage and matched subjects, who controlled the duration of viewing of background, novel and target stimuli. Frontal lobe patients did not differ from normal controls in terms of age, education, estimated IQ or mood. However, they were judged to be more apathetic as measured by self-report and informants' ratings. Patients with frontal lobe damage exhibited markedly reduced amplitude of the novelty P3 response and the duration of viewing of novel stimuli. In contrast, injury to the frontal lobes had a limited impact on P3 amplitude and behavioural responses (viewing duration and reaction time) to target stimuli. A strong correlation was found between measures of apathy and both attenuated P3 amplitude and viewing duration in response to novel but not target stimuli. Differences in amplitude of the novelty P3 response explained a large portion of the variance associated with duration of viewing of novel stimuli. After controlling for the influence of P3 amplitude, there was no association between frontal lobe injury and reduced viewing of novel stimuli. The results of this study suggest that frontal lobe damage leads to diminished visual attention to novel events through its disruption of neural processes underlying the novelty P3 response. These processes appear to regulate the allocation of attentional resources and early exploratory behaviours, and are not limited to immediate orienting responses. Damage to the frontal lobes may prevent the generation of a signal which indicates that a novel event in the environment requires additional attention due to its potential behavioural significance. The disruption of these processes is likely to contribute to the apathy observed in patients after injury to the frontal lobes.

Disruption of attention to novel events after frontal lobe injury in humans.

OBJECTIVE: To investigate whether frontal lobe damage in humans disrupts the natural tendency to preferentially attend to novel visual events in the environment. METHODS: Nine patients with chronic infarctions in the dorsolateral prefrontal cortex (DLPFC) and 23 matched normal controls participated in a study in which subjects viewed repetitive background stimuli, infrequent target stimuli, and novel visual stimuli (for example, fragmented or "impossible" objects). Subjects controlled viewing duration by a button press that led to the onset of the next stimulus. They also responded to targets by pressing a foot pedal. The amount of time spent looking at the different kinds of stimuli, and the target detection accuracy and speed served as dependent variables. RESULTS: Overall, normal controls spent significantly more time than frontal lobe patients looking at novel stimuli. Analysis of responses across blocks showed that initially frontal lobe patients behaved like normal controls by directing more attention to novel than background stimuli. However, they quickly began to distribute their viewing time evenly between novel and background stimuli, a pattern that was strikingly different from normal controls. By contrast, there were no differences between frontal lobe patients and normal controls for viewing duration devoted to background and target stimuli, target detection accuracy, or reaction time to targets. Frontal lobe patients did not differ from normal controls in terms of age, education, estimated IQ, or mood, but were more apathetic as measured by self report and informants' judgments. Attenuated responses to novel stimuli significantly correlated with degree of apathy. CONCLUSIONS: This study demonstrates that DLPFC injury selectively impairs the natural tendency to seek stimulation from novel and unusual stimuli. These data provide the first quantitative behavioural demonstration that the human frontal lobes play a critical part in directing and sustaining attention to novel events. The impairment of novelty seeking behaviour may contribute to the characteristic apathy found in patients with frontal lobe injury.

Effects of different inotropes with antioxidant properties on acute regional myocardial ischemia in isolated rabbit hearts.

1. The antiischemic properties of the flavonoids acetylvitexin-rhamnoside (AVR) and luteolin-7-glucoside-(LUT), combining phosphodiesterase (PDE)-inhibitory and antioxidant properties, were studied in comparison to amrinone (AMR) or superoxide dismutase (SOD). The effects of the new dihydropyridine-type calcium-agonist Bay T 5006 were studied in comparison to Bay K 8644. 2. In isolated Langendorff-rabbit hearts perfused at constant pressure, acute regional ischemia (MI) was induced by coronary artery occlusion (CAO) and quantitated from epicardial NADH-fluorescence photography. Drugs were applied either before or after CAO (pre-treatment or treatment) to permit distinguishing the influence of functional and direct cytoprotective actions in the poorly collateralized rabbit hearts. 3. SOD did not affect left ventricular pressure (LVP) or coronary flow (CF) and reduced MI only if applied before CAO. LVP and CF were enhanced by LUT or AMR but not by AVR. MI was reduced to a similar extent in hearts treated with either drug. Cardioprotection by LUT was not improved by starting drug application before CAO. 4. Bay K 8644 reduced LVP and particularly CF, whereas Bay T 5006 did not affect functional parameters. MI was enlarged by Bay K 8644 and remained unaffected by treatment or pretreatment with Bay T 5006. 5. AMR, LUT and AVR possess antiischemic properties related to an improvement of myocardial perfusion. Although oxygen free radicals contribute to ischemic tissue injury, as shown by the cardioprotective effectiveness of SOD, antioxidant properties of the flavonoids LUT and AVR do not seem to be relevant for the antiischemic effects. Our findings also give no evidence for antioxidant properties of dihydropyridines relevant for cardioprotection.

Functional and antiischemic effects of luteolin-7-glucoside in isolated rabbit hearts.

1. The functional effects of the flavonoid luteolin-7-glucoside (LUT) were investigated in Langendorff-rabbit hearts perfused at constant pressure. Repetitive myocardial ischemia was induced by coronary artery ligature and quantified from NADH-fluorescence photography. 2. LUT significantly enhanced left ventricular pressure and the global and relative coronary flow (= global coronary flow/pressure-rate product). 3. LUT significantly diminished epicardial NADH-fluorescence area and intensity. 4. LUT is an inodilator possessing cardioprotective properties. These might be related to an improvement of myocardial perfusion and/or to free radical scavenging properties.
