ABSTRACT: In case of Sitopbilus oryzae, Periplaneta americana and Gumbusia affinis (girard), 100 % mortality was noted after 24 hours of exposure to the crude extracts and the isolated compounds where as in control group 100% survival was noted. In the initial stage of the experiment on Sitopbilus oryzae, after 30 minutes of exposure, schooling behavior was observed. After 30 minutes the weevils were dispersed there after towards the corners of the petridishes. After 1hour the locomotary movement of the weevils was restricted and these weevils could not be moved afterwards. The Periplaneta americana showed cleaning behavior at the initial stages of poisoning by rubbing their bodies with their legs or sides of the cages. At the later stages of poisoning Periplaneta americana shows incoordination and convulsion leading to paralysis. Gumbusia affinis showed hypersensitivity, an increased respiratory rate by indicating rapid operculum movement. The fishes were become restless and the movement of the body and operculum of fishes becomes lower down and the fishes were settled down at the bottom of the aquarium. At the final stages of intoxication after 24 hours the fishes were dead and found floating on the surface of the aquarium. The area of the brain of dead fishes was found red in color. From the above symptoms it was evident that the toxin found in the crud extract and the isolated compounds of Tetraodon fluviatilis may contains strong toxin.

Background. Morphometry, the measurement of forms, is an ancient practice. In particular, schizophrenic somatology was popular early in this century, but has been essentially absent from the literature for over 30 years. More recently, evidence has grown to support the notion that aberrant neurodevelopment may play a role in the pathophysiology of schizophrenia. Is the body, like the brain, affected by abnormal development in these patients?Methods. To evaluate global deficit in development and its relationship to pre-morbid function, height was compared in a large group (N=226) of male schizophrenics and a group of healthy male controls (N=142) equivalent in parental socio-economic status. Patients in the lower quartile of height were compared to those in the upper quartile of height.Results. The patient group had a mean height of 177·1 cm, which was significantly shorter than the mean height of the control group of 179·4 (P<0·003). Those in the lower quartile had significantly poorer pre-morbid function as measured by: (1) psychosocial adjustment using the pre-morbid adjustment scales for childhood and adolescence/young adulthood, and (2) cognitive function using measures of school performance such as grades and need for special education. In addition, these measures of pre-morbid function correlated significantly with height when analysed using the entire sample.Conclusions. These findings provide further support to the idea that abnormal development may play a key role in the pathophysiology of schizophrenia. Furthermore, this is manifested as a global deficit in growth and function resulting in smaller stature, poorer social skills, and deficits in cognitive abilities.

The immune response in animals and hu-mans is a biological defense mechanism against negative environmental factors. The immune system is a complex of organs and cells of the body, that reacts (protects) against foreign objects-protozoas and hel-minths. The aim of the study was to investi-gate the dynamics of cellular factors of the immune system of healthy minks, experi-mentally invaded with eimeriidosis against the background of specific immunocorrec-tive therapy. To study the dynamics of T-lymphocytes in the blood of animals, being at the specific immunocorrective therapy, a single-center prospective blind randomized comparative study was conducted in parallel groups. At the initial stage of the study, 56 male minks were isolated from the general population. The first group of clinically healthy animals was the control group. From the second to the sixth groups, animals were spontaneously infected with eimerias and isospores. Animals from the third and fifth groups were treated with coccidiostatic "Stop-coccid". Mink of the 4th and 6th groups received the drug "Ametherm 5%". Minks in the 5th and 6th groups after treat-ment with coccidiostatic were adninistered an immunomodulatory drug of plant origin "Phytodoc-immunostim". The 7th group served as an additional control and received a placebo-water with starch. Thus, the analy-sis of the results of the clinical study showed that the use of specific and immunocorrec-tive therapy has a positive effect on the dy-namics of T-lymphocyte levels in the blood of animals with eimeriidosis. In group 3, where infected minks were treated with "Stop-coccid", the level of T-lymphocytes increased by 35.8% to 41.1%; in the 4th group (administered "Ametherm 5%") the level of T-lymphocytes rose from 35.2% to 42.3%; in the 5th group (administered “Stop-coccid” and immunomodulator) the level of T-lymphocytes changed from 36.5% to 43,0% in the 6-th experimental group (treated "Ametherm 5%" and immunomodu-lator) the level of T-lymphocyte growth from 38.6% to 43.9 per cent.

Purpose: The purpose of this study was to investigate how intravenously injected bone marrow-derived mesenchymal stem cells (BMSCs) are distributed in the body of an Alzheimer’s disease (AD) animal model. Methods: Stem cells were collected from bone marrow of mice and labeled with Indium-111 (111In). The 111In-labeled BMSCs were infused intravenously into 3×Tg-AD mice in the AD group and non-transgenic mice (B6129SF2/J) as controls. Biodistribution was evaluated with a gamma counter and gamma camera 24 and 48 h after injecting the stem cells. Results: A gamma count of the brain showed a higher distribution of labeled cells in the AD model than in the control group at 24 (p = .0004) and 48 h (p = .0016) after injection of the BMSCs. Similar results were observed by gamma camera imaging (i.e., brain uptake in the AD model was significantly higher than that in the control group). Among the other organs, uptake by the spleen was the highest in both groups. More BMSCs were found in the lungs of the control group than in those of the AD group. Conclusions: These results suggest that more intravenously infused BMSCs reached the brain in the AD model than in the control group, but the numbers of stem cells reaching the brain was very small.

Obesity is one of the most common complex health problem. The pathway of serotonin synthesis takes part in neuroendocrine regulation, as well as in the regulation of a number of behavioral functions of the body and fat deposition. Serotonin is a mediator of the amine nature, which functions as a neurotransmitter and tissue hormone. The greatest amount of serotonin is synthesized in the brain and 12 duodenum. As a neurotransmitter, serotonin affects both directly and indirectly on the function of most brain cells. Female hormone progesterone influence on serotonin functions. One of the effect of progesterone is increasing of amount of fat tissue during the pregnancy. Long-term using of progesterone in hormone substitution therapy or as part of contraception also lead to fat accumulation effect. The levels of activity of serotonergic system enzymes, tryptophan hydroxylase, tryptophan decarboxylase and monoamine oxidase (MAO), and tryptophan, 5-hydroxytryptophan, serotonin and 5-hydroxyindoleacetic acid concentrations in the rat brain under obesity conditions caused by prolonged administration of progesterone were determined in this study. Studies have shown that the content of tryptophan, 5-hydroxytryptophan, serotonin and 5-hydroxyindoleacetic acid in the brain of rats under obesity caused by prolonged administration of progesterone increased in comparison with the rats of the control group. The levels of tryptophan hydroxylase and MAO activity decreased, and tryptophan decarboxylase activity levels increased in the rat brain under obesity conditions caused by prolonged administration of progesterone. Thus, as a result of our studies, we found an imbalance in the system of serotonin metabolism in the brain of rats with the development of hormonal obesity induced by prolonged administration of progesterone, which may indicate the involvement of the serotonergic neurotransmitter system in the mechanisms of the development of obesity and concomitant diseases.

Purpose An area of workplace well-being, and thus performance, which is now being recognized more widely is the mental health of employees. Research today demonstrates that exercise is good for the body and dramatically affects the brain. While it is widely accepted that regular exercise can promote weight loss, lower blood pressure and decrease the risks of diabetes, heart disease and certain cancers, it is also becoming clear that exercise can improve mood, coping skills and even treat clinical depression and anxiety. These findings further support the upward trend of companies offering a wider range of health benefits to their employees. Design/methodology/approach One example of the combined research, Rethorst et al., published a large meta-analysis exploring the interaction between physical activity and depression. They examined 58 randomized trails and found that participants in the studies who had been randomized to use exercise as a treatment for depression had significantly lower depression scores than participants who had been randomized to the non-exercise or “control” group. Both clinically depressed and non-clinically depressed individuals reported lower depression scores if they participated in the exercise group. Findings Exercise can be as effective as medication in treating depression. Regular exercise can decrease the symptoms of clinical anxiety. Employers who incentivize physical activity can dramatically lower healthcare costs. Benefits packages which promote physical activity can increase productivity and decrease absenteeism. Originality/value There will always be people with an illness which requires medication, but there appears to be a group that will benefit greatly from getting out and moving with regular exercise. The hope is that physicians with patients who have symptoms of depression and anxiety will encourage their patients to get some exercise to see if it helps. This can be something that is done alone or as an adjunct to talk therapy and/or pharmacologic treatment. Exercise is not likely to change the circumstances that make life challenging, but it can help all humans cope better with these challenges.

Introduction: Goko cleanser is one of the popular herbal mixtures used by the Nigerian populace. This study was carried out to evaluate the effects of this herbal mixture on some haematological parameters of adult female Wistar rats. Methodology: A total of twenty five Wistar rats weighing about 160 – 280g were divided into five groups according to their corresponding weights. The groups were designated as groups 1 – 5. Group 1 served as the control group, while groups 2, 3, 4, and 5 received 1000mg/Kg, 1500mg/Kg, 2000mg/Kg and 4000mg/Kg respectively. Results: The TWBC, PCV, PLATELET count, and RBC and Hb showed a statistically significant (p<0.05) increase for the test groups 2 – 5 when compared to the control group. The body weight had a statistically significant (p<0.05) decrease in groups 2, 4, and 5; while group 3 had a statistically insignificant (p>0.05) decrease. Conclusion and Recommendation: This study revealed that Goko Cleanser contains some haemopoietic benefits, but inhibit appetite centres. Hence, this study recommends that further study be carried out on the effects of this herbal mixture on the brain so as to reveal the extent of its effect on the appetite centres.

O Manganês (Mn) é um metal essencial para o organismo. É distribuído no ambiente e utilizado em processos industriais. Apesar de essencial, é neurotóxico à exposições cumulativas, causando uma desordem neurológica, o Manganismo. O estudo avaliou o efeito da administração subaguda de Mn sob a forma de cloreto e acetato de Mn, sobre a função mitocondrial e parâmetros oxidativos no encéfalo, bem como o acúmulo deste metal no encéfalo e tecidos periféricos de ratos adultos. Os ratos receberam 6 mg/kg de Mn i.p. na forma de cloreto ou acetato de Mn, 5 dias/semana por 4 semanas. O grupo controle recebeu solução salina 0,9% pela mesma via de administração e mesmo período. Foi mensurada a concentração de substâncias reativas ao ácido tiobarbitúrico (TBARS) e grupamentos NPSH, a atividade dos complexos I e II da cadeia respiratória no encéfalo e/ou estruturas cerebrais, bem como o peso corporal e a concentração de Mn e Fe no soro, encéfalo, tecido renal e hepático. Foi observada uma diminuição no ganho de peso corporal dos animais que receberam o Mn, um aumento na concentração/depósito de Mn no soro, encéfalo e tecido renal, tanto na forma de cloreto e acetato de Mn, quando comparados com o grupo controle. Além disso, houve um aumento significativo no conteúdo de NPSH no encéfalo e, embora não significativo, uma tendência de aumento da concentração de TBARS, no grupo que recebeu cloreto de Mn. Ainda, foi verificada uma inibição na atividade do complexo I no estriado dos animais expostos ao cloreto de Mn. Não houve diferença entre os grupos nas atividades do complexo I e II no encéfalo e hipocampo. Em conjunto, os dados indicam que a exposição ao Mn em baixas doses contribui para o desenvolvimento de estresse oxidativo e disfunção mitocondrial no SNC, com aparente predileção de dano ao estriado.Palavras-chave: Manganês.

It is distributed in the environment and used in industrial processes. Although essential, it is neurotoxic to cumulative exposures, and can cause a neurological disorder, called Manganism. This study evaluated the effect of subacute Mn as chloride and acetate of Mn administration on mitochondrial function and oxidative parameters in adult rat brain, as well as the accumulation of this metal in the brain and peripheral tissues. The rats received 6 mg/kg of Mn i.p., as Mn chloride or Mn acetate, 5 days/week for 4 weeks. The control group received 0.9% of saline solution in the same way of administration and in the same period. It was measured the concentration of thiobarbituric acid reactive substances (TBARS) and NPSH groups, the activity of mitochondrial complex I and II in brain and/or in the brain structures, as well as the body weight and the concentration of Mn and Fe accumulation. It was observed a decrease on body weight gain in animals exposed to Mn and an increase of concentration/deposit of Mn in serum, brain and kidney, in the both Mn chloride and acetate form when compared to the control group. In addition, there was a significant increase in brain NPSH content and, although it was not significant, a trend of increasing on TBARS concentration in the group that received Mn. Besides that, a significant inhibition of complex I activity was observed in the striatum of the animals exposed to Mn. There was not difference between groups on complex I and II in the brain and hippocampus. Together, these data indicate that exposure to Mn at low doses contributes to the development of oxidative stress and mitochondrial dysfunction in the CNS, with apparent predilection of striatum damage.Keywords: Manganese.

Among vascular brain diseases a special place in its importance takes chronic cerebrovascular pathology in the form of dyscirculatory encephalopathy. The most frequently affected cerebral structures with discirculatory encephalopathy are those parts of the brain that are largely responsible for shaping over segmental vegetative disorders, which are characteristic of clinics chronic cerebrovascular insufficiency. The purpose of this work is to develop a new modern high technology of sanatorium rehabilitation of the patients with circulatory encephalopathy on stage I and to correct autonomic imbalance. The authors observed 60 patients who were divided into 2 groups. The control group received radon baths, the patients from the main group in addition to radon baths received laser therapy paravertebrally C1-Th3, according to scanning technique. In all patients before and after treatment the state of the autonomic nervous system studied. It was found that the initial manifestations of vascular encephalopathy accompanied by autonomic imbalance with a predominance of sympathetic tone, activation and inhibition effects of ergotrop activities segmental systems, primarily due to the parasympathetic division. The results of this study demonstrate feasibility of incorporating laser therapy in complex radon baths for rehabilitation of patients with circulatory encephalopathy autonomic imbalance. The findings suggest that improving the functional state mechanisms vegetative maintenance activities, which help to eliminate the state of surge and flow of adaptive reactions in the body.

The effect of maternal dietary deficiency on the metabolism of nucleic acids and proteins was studied by exchanging the pups of control and undernourished dams during the lactation period. In the pups of control dams fostered by undernourished dams during the lactation period (E3), it was observed that the body and organ weight, and RNA, DNA, and protein content failed to increase normally. Contrary to this, the free leucine and nucleotide contents were higher and their specific activities lower in the plasma and various organs of the E3 group as compared with the control group.Specific activity of protein was higher in the liver, brain, kidney, and lung, and was lower in the spleen and heart of the E3 group as compared with the control group. Specific activity of RNA was higher in the liver, spleen, and lung, and was lower in the brain, kidney, and heart of the E3 group as compared with the control group.In the pups of undernourished dams fostered by the control dams during the lactation period (E1), the body and organ weights, the RNA, DNA, and protein content, the content of free leucine and nucleotides as well as their specific activities, and the specific activity of protein and RNA were partially or completely restored. However, the DNA content of the brain remained unchanged in comparison with those pups of undernourished dams nursed by their own mother (E2). In the brain, kidney, spleen, and lung of the E1 group, the specific activity of RNA increased considerably and even exceeded the control values.The radioactivity results discussed above clearly demonstrate an accelerated metabolism of protein and RNA in the various organs of the E3 group and a partial or complete normalization in the E1 group.

AbstractThe impact of alcohol on the body can be investigated with NMR spectroscopy in vitro, which can detect a wide range of metabolites but preparing samples includes tissue biopsy. Blood sampling is less invasive, but blood metabolic content might not reflect the changes occurring in other tissues. Thus, this study aimed to investigate the liver, brain, and serum metabolism and evaluate the link between tissues and serum metabolic content. Two experimental groups with ten outbred rats each were provided intragastrically with water (control group) and 50% ethanol solution (alcohol group) for 28 days. 1H NMR spectroscopy in vitro was performed on the brain cortex, liver, and serum samples. Student’s t test with Holm–Bonferroni correction was used to investigate significant differences between groups. Partial least-squares discriminant analysis (PLS-DA) and two-way ANOVA were performed to compare liver and serum, brain and serum. In all, 38, 37, and 21 metabolites were identified in the liver, brain, and serum samples, respectively. Significant differences for three metabolites were found in the liver (alanine, proline, and glutathione, p < 0.002) and four in serum (lactate, betaine, acetate, and formic acid, p < 0.002) were detected between the control and alcohol groups. The contents of glucose, betaine, and isoleucine were correlated (r > 0.65) between serum and liver samples. PLS-DA determined separation between all tissues (p < 0.001) and between control and alcohol groups only for liver and serum (p < 0.001). Alcohol had a more substantial effect on liver and serum metabolism than on the brain.
