Methods: The rat pups of GC and Wistar strains of different ages ranging from 1 to 14 days were tested by motor subsystem test. The following parameters were accounted: head movements, body movements, locomotion (pacing), immobility time, asymmetric postures during immobility periods, falls onto the back, retropulsions, body tremor, and swimming-like movements. Brain monoamine levels and corticosterone in blood plasma were assayed. The body and organ weights were measurement. Results: Preceding signs of catatonia have been noted in postnatal development in GC pups: (a) the prevalence of dyskinetic movements in the first days; (b) reduction in motor activity; (c) imbalance between the brain serotonin and noradrenaline levels; (d) increased plasma corticosterone concentration; (e) underweight at 1, 7, 10 and 14 days during early development, and the relatively larger weight of the brains and kidneys in GC rats compared with Wistar control. Conclusion: The entire range of observed abnormalities in the behavioral, neurotransmitter, hormonal, and general physical systems may be viewed as prodromal signs of catatonic reactions in GC rats.","PeriodicalId":16091,"journal":{"name":"Journal of Experimental and Integrative Medicine","volume":"22 1","pages":"99-108"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83340235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study therefore aimed to investigate the effect of an ethanolic seed extract of P.nitida on reproductive abilities and developmental indices and to establish its safety for use. \u0000Methods: Secondary metabolite screening, and safety assessment to estimate the NOAEL, and LD50 of P.nitida were conducted. Mating, estrous, fertility, live birth, and weaning indices, and the gestation period in female rodents pretreated with P.nitida (10-1000 mg/kg) for 14 days were determined. In males the number of attempted mounts, sniffing, licking, genital and non-genital grooming, and hesitation time to female, in reproductive orientation (mating) behavior studies were determined with P.nitida treatments. Spermatocyte count and quality (morphology, motility and viability) as well as histopathological study of the seminiferous tubules were also performed. \u0000Results: P.nitida, which had alkaloids, tannins, steroids, glycosides, anthraquinones and terpenoids, present a NOAEL 2000 mg/kg. Treatment with P.nitida in females significantly reduced fertility index (40%), caused dose-dependent reduction in litter size and increased estrous index. Mating index, gestation period, live birth index and weaning index were not affected. In males, there was a significant increase P.nitida-induced sniffing, licking, genital and non-genital grooming and attempted mounts with acute (but not prolonged) treatment. Treatment also significantly reduced the hesitation time of males for attraction towards females and sperm count. Spermatocyte morphology, motility and viability was not affected. Histopathological studies indicated progressive degenerative changes in the seminiferous tubules with increasing P.nitida doses. \u0000Conclusion: Picralima nitida enhances sexual behaviors in both males and females. However, chronic administration reduces fertility in females and sperm count in males; at relatively lower doses the extract is safe to use.","PeriodicalId":16091,"journal":{"name":"Journal of Experimental and Integrative Medicine","volume":"23 1","pages":"200-208"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87537995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Fractions of human placenta extract (HPE) were obtained with gel-chromatography method. Spontaneous hemolysis of erythrocytes was measured spectrophotometrically by free hemoglobin content in supernatant at 543 nm wavelength. Osmotic fragility (resistance) of erythrocytes was assessed by the level of hemolysis in 0.45% NaCl solution. Low-pH resistance of erythrocytes was evaluated by the time of 50% hemolysis in sodium-phosphate-citrate buffer (pH 3.8), calculating the data from kinetic curve of the change of optical density at 700 nm. Electron paramagnetic resonance (EPR) spin probe method was applied for analysis of cytosol dynamic state. Results: We recorded that low temperature storage of placental tissue allows decreasing membranotropic effect, which was inherent to certain aqueous-saline placental extracts and some of their fractions. At the same time, storage of placental tissue at both 20 С and 196 С does not influence the ability of HPE to decrease erythrocyte osmotic fragility. Erythrocytes exposed with HPE derived from placenta stored for 6 months at 20 С displayed decrease of low-pH resistance. This effect was inherent not only to the whole placental extract, but also to its certain fractions, especially those with molecular weight below 5 kDa. Conclusions: Storage of placental tissue at 196 С seems to be advantageous for preservation of studied properties of placental aqueous-saline extract in comparison to storage at 20 С.","PeriodicalId":16091,"journal":{"name":"Journal of Experimental and Integrative Medicine","volume":"33 1","pages":"172-177"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77595546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aimed to evaluate the protective effect of Ipomoea carnea Jacq leaves extracts on streptozotocin (STZ)-induced oxidative stress in rats. Methods: Alterations in stress biomarkers like activities of superoxide dismutase, catalase, glutathione peroxidase, and levels of blood glutathione and malondialdehyde in experimental groups administered with STZ alone and along with aqueous or alcoholic extracts of I.carnea were determined. Results: Single intra-peritoneal administration of STZ (60 mg/kg) caused significant decrease in activities of superoxide dismutase, catalase, glutathione peroxidase, and blood glutathione levels while malondialdehyde level as an indicative of oxidative stress significant increased. Administration of I.carnea extracts at the dose rate of 500 mg/kg body weight through oral gavage continuously for 3 weeks in STZ-treated group reduced malondialdehyde level significantly and increased activities of superoxide dismutase, catalase, glutathione peroxidase, and blood glutathione level as compared to STZ alone treated rats; however, the values of antioxidants remain still lower in comparison to normal control rats.

Many studies have shown intestinal dysbiosis in children with autism. Moreover, gastrointestinal disturbances, probably resulting from abnormal microbiota composition, are commonly reported in children with autism. Another aspect, that may have negative influence on ASD children’s behavior are enzymopathies (enzymatic deficiency). Lack of selected gastrointestinal enzymes leads to inappropriate nutrients decomposition (mainly gluten and casein) and formation of so called exorphins, i.e. substances with opioid activity (opioid therapy). Because of increased permeability of the intestinal barrier and cerebrospinal axis, exorphins and others improperly digested food particles may be transported to the central nervous system. Consequently, disorders in brain development and children’s behavior deterioration may be observed.

Results: The sciatic nerve showed variations in its formation and as well as termination. High division of the sciatic nerve was the most commonly encountered variation (45%). The relationship of the sciatic nerve and its branches with the piriformis muscle was also variable. In majority of the cases (56.67%), the sciatic nerve and its branches were passing inferior to piriformis.
