OBJECTIVE: Chronic infections in the urogenital area often precede or coexist with vulvar cancer. A strong connection between some tumours and the-appearance of Chlamydia trachomatis infection has been observed, but there is little information concerning a connection of that infection with vulvar cancer and lichen sclerosus vulvae (LS). The aim of this study was the analysis of frequency of antigens appearance and antibodies of IgM and IgG Chlamydia trachomatis in patients with vulvar cancer and LS and we wanted to find the correlation between Chlamydia trachomatis infection and vulvar cancer and LS.r />r /> METHODS: 80 women treated in the Clinic of Vulva Diseases at the Department and Clinical Ward of Gynaecology, Obstetrics and Oncological Gynaecology in Bytom, in the Silesian Medical University in Katowice were divided into two groups - 30 were treated for vulvar cancer and 50 were treated because of LS. We took bacterial smears vagina and cervical smears for presence of Chlamydia trachomatis antigens and peripheral blood to mark antibodies of IgM and IgG Chlamydia trachomastis.r />r /> RESULTS: Chlamydia trachomatis antigen was found in 20% women with vulvar cancer and in 12% women with LS (p>0.05). In 13,3% cases with vulvar cancer we observed IgM Chlamydia trachomatis antibodies. In the group with LS IgM antibodies appeared in 16% women (p>0.05). In 50% patients with vulvar cancer in blood serum we observed IgG Chlamydia trachomatis antibodies, and in 16% women with LS (p<0.001).r />r /> CONCLUSIONS: Previous Chlamydia trachomatis infection can lead to vulvar carcinogenesis....

OBJECTIVE: The relationship between epilepsy and sleep has been known for many years. Yet is still not well understood because of it's reciprocal and intrinsic influences. Epileptic manifestations during sleep may lead to fragmentation of sleep stages. On the other hand insomnia or other sleep disorders may cause sleep deprivation and increase number of epileptic seizures in patients with epilepsy. The study is designed to compare daytime sleepiness and architecture of sleep in patients with epilepsy and control subjects. We tried to evaluate factors that have influence on sleep architecture of patients with epilepsy.r />r /> METHODS: We evaluated the daytime sleepiness through a certain type of questionnaire called Epworth Scale of Sleepiness (ESS). The questionnaire was filled out by patients with epilepsy (83 patients) and a group of healthy controls (80 persons). Furthermore we evaluated the quatity of night sleep in both groups using polysomnograph (electroencephalography - EEG, electrooculography - EOG, electromyography - EMG). Sleep stages were scored according to Manual of Standardized Terminology, Techniques and Scoring System for Sleep Stages of Human Subjects (Rechtschaffen, Kales, 9). Multiple sleep latency test (MSLT) was performed in the group of patients with epilepsy in order to objectivise daytime sleepiness.r />r /> RESULTS: Measuring by Epworth scale of sleepiness we found out that the patients with epilepsy suffered from a significantly higher daytime sleepiness than the healthy controls. Patients with epilepsy also experienced significant changes in sleep architecture, the reduction of NREM S3, S4 and REM stages and the increase of NREM S2 stage. These changes were not related to used antiepileptic medication....

BACKGROUND: Developmental study of dopaminergic and noradrenergic systems in child psychiatric disorders are rare. DBH activity is one of noradrenergic biochemical marker that is correlate in psychiatry to clinical and genetic data.r />r /> OBJECTIVES: The main aim of the present study was to measure DBH activity at the onset of acute schizophrenia and depressive disorder in children and adolescents without pharmacological treatment and to compare these values with DBH activity in healthy controls. The authors also investigated untreated ADHD children.r />r /> METHODS: We examined 42 control healthy children, 15 children non-treated with acute schizophrenia, 15 non-treated children with acute depressive disorders and 30 non-treated ADHD children, all in age 7-14. Plasma DBH level was provided by Nagatsu (1972; 1974). Depressed children were reexamined after clinical remission.r />r /> RESULTS: DBH activity is statistically significantly decreased in non-treated depressive disorder and ADHD in children and adolescents. DBH activity is normalised during antidepressant therapy in child depression. Child schizophrenia patients present with normal DBH activity.r />r /> CONCLUSION: These results are similar to the results that have been observed in adult patients with schizophrenia and depression and in previous studies of DBH activity in children with ADHD. These results also indicate hypoactivity of the noradrenergic system in children with ADHD and depression....

OBJECTIVES: The idea of neuroprotective therapy for ischaemic stroke is based on results from studies on experimental animal models of brain ischaemia demonstrating efficacy of many natural and synthetic agents. Contrary to positive conclusions with antioxidants from animal models, clinical experience failed to find neuroprotectants so efficient in human stroke, infarction, brain trauma, tissue preservation, etc. Thus new highly effective neuroprotective agents need to be discovered.r />r /> METHODS: Effects of 10-day oral treatment with the new pyridoindole derivative, code SMe1EC2, was analysed in the model of ischaemia in vitro measured five days after oral treatment, with focus on neuronal function recovery. The responses were determined by extracellular recording from rat hippocampal slices. Further, effect of SMe1EC2, applied into the incubation medium before and during ischaemia in vitro, was studied on the oedema extent in neurons of the CA1 area.r />r /> RESULTS: Ten-day oral treatment of rats with SMe1EC2 at the doses 50 or 250 mg/kg resulted in improved resistance of hippocampal neurons to 6.5-min hypoxia/hypoglycaemia in vitro measured during reoxygenation, compared to untreated rats. Application of the drug tested into the incubation medium 30 min before and during 6-min hypoxia/hypoglycaemia resulted in reduction of oedema formation in the CA1 area compared to untreated slices exposed to ischaemia in vitro.r />r /> CONCLUSION: The current study confirmed the neuroprotective effect of the pyridoindole antioxidant SMe1EC2 on the level of recovery of neuronal function as well as on affection of morphological changes expressed by reduced oedema extent in the rat hippocampus under ischemic conditions in vitro....

OBJECTIVE: The aim of this study was to determine whether there is an association between ultrasound fetal biometry and lipids and glucose profiles at the beginning of gestational diabetes (GDM) treatment.r />r /> METHODS: In 98 women with GDM plasma glucose and lipid profile were measured between 27-32 weeks' of gestation. The association between the biochemical parameters and the measurements and percentiles of the biparietal diameter (BPD), femur length (FL) and abdominal circumference (AC), estimated fetal weight (EFW) and the actual birthweight (BW) were analyzed.r />r /> RESULTS: There was no significant association between fetal and neonatal biometry measurements and maternal glucose concentrations. Highly significant positive correlation was found between triglicerydes and fetal biometry at the beginning of GDM treatment: AC, BPD, FL and EFW (p=0.007, p=0.018, p=0.018, p=0.013, respectively), as well as between total cholesterol and bi-parietal diameter (p=0.04). Associations between maternal plasma lipids and birthweight or birthweight percentile were not evident.r />r /> CONCLUSIONS: These data suggest that maternal lipids and carbohydrates metabolic disturbance are an important determinant for fetal growth in pregnancy before gestational diabetes is diagnosed....

BACKGROUND: There is now evidence that major depression and myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) are accompanied by partially overlapping pathophysiological mechanisms, i.e. activation of various inflammatory and oxidative & nitrosative (IO&NS) pathways.r />r /> OBJECTIVE: The aim of the present study was to examine the urinary excretion of 8-hydroxy-deoxyguanosine (8-OhdG), a marker of oxidative damage to DNA, in depression; ME/CFS; and depression and ME/CFS.r />r /> METHODS: Toward this end, morning urine was sampled for the assays of 8-OHdG and creatinine, in 44 patients with ME/CFS; 25 with major depression; 23 with depression and ME/CFS; and 17 normal controls. Severity of fatigue and somatic symptoms was measured by means of the Fibromyalgia and CFS Rating (FF) scale.r />r /> RESULTS: We found that 49.0% of the variance in the urinary excretion of 8-OHdG was predicted by the regression on creatinine. Consequently, the urinary 8-OHdG excretion should be expressed as the residualized 8-OHdG values after partialling out the effects of creatinine and not by computing the 8-OHdG / creatinine ratio. We found that the residualized urinary excretion of 8-OHdG (adjusted for creatinine) was significantly higher in patients with depression and ME/CFS than in normal controls and all other patients. In the patient group, there were significant correlations between the urinary 8-OHdG and the total score on the FF scale and sadness and flu-like malaise.r />r /> CONCLUSIONS: The findings show increased oxidatively generated DNA damage in patients with major depression and ME/CFS and, therefore, further extent the role played by IO&NS pathways in the pathophysiology of both disorders. Since oxidatively damage to DNA is a risk factor for atherosclerosis and neurodegeneration, our results also explain previous findings on increased cardiovascular morbidity in depression and ME/CFS, and neurodegenerative processes in depression....

OBJECTIVE: The female animals were already recorded to respond differently to methamphetamine (MET) abuse than males. This gender dissimilarity may be caused by the influence of estral cycles and different susceptibility to behavioural sensitization.r />r /> METHODS: Influences of gender and pre-exposure to MET were studied in the rat model of MET intravenous self-administration (IVSA). The fixed ratio (FR) paradigm was employed in male rats (M) and estrogenized (F-ESTR) and non-estrogenized ovariectomized female rats (F-OVX) either pre-exposed or not-exposed to MET pretreatment.r />r /> RESULTS: In rats that were not pre-exposed to MET, F-ESTR self-administered more MET infusions than each of the other groups, but F-OVX self-administered less than each of the other groups; the same trend was apparent in the MET pretreated groups. MET pre-exposure decreased subsequent MET IVSA in all groups except F-OVX.r />r /> CONCLUSION: Thus, pre-exposure to MET and the loss of inherent estrogen in females notably decreased the intake of MET by rats, suggesting that abuse liability was reduced. Estrogen's effects on MET self-administration here correspond with accumulating evidence of stronger behavioural responses of females to drugs of abuse....

OBJECTIVE: Our earlier studies have shown that MLT exerts the inhibitory effect on murine cancer via membrane and nuclear receptors. We have found that the antagonist of MT1 receptors does not diminish the antiproliferative effect of MLT on Colon 38 cells, and the contribution of MT2 receptors has been suggested to be responsible. Therefore, in the present study we have examined the influence of the 4-phenyl-2-propionamidotetralin (4P-PDOT), which is a selective antagonist of MT2 membrane receptor, and luzindole - an antagonist of both membrane receptors, on an oncostatic action of MLT.r />r /> MATERIALS AND METHODS: The murine cancer cell line Colon 38 was used in the experiments. In 48 hrs cell culture the effects of MLT, 4P-PDOT and luzindole administered alone and MLT applied jointly with either 4P-PDOT or luzindole were examined. The growth of cancer cells was assessed using the modified colorimetric Mosmann method.r />r /> RESULTS: Melatonin at both examined concentrations (10-7, 10-9 M) significantly decreased the viability of cancer cells. The selective antagonist of MT2 membrane receptor, namely 4P-PDOT and luzindole applied separately did not have an effect on the growth of Colon 38 cells. The addition of 4P-PDOT to MLT did not change the inhibitory effect of MLT, whereas luzindole given together with MLT diminished, but failed to block totally, the oncostatic properties of MLT.r />r /> CONCLUSIONS: The obtained data and our previous studies conducted on Colon 38 cancer indicate that membrane melatonin receptors are not indispensable to the oncostatic action of melatonin and thus other pathways such as nuclear signaling and receptor-independent mechanism may be also involved....
