In the present study, the GC-MS profiles and effect of ethanolic extracts of stem bark and leaves of Daniellia oliveri on lipid peroxidation, Na+/K+-ATPase activity and thiols status in H2O2 and Fe2+ (fenton reaction) assaulted cerebral and hepatic tissue homogenates was investigated. The stem bark and leaves were extracted with absolute ethanol for 72hrs and concentrated in a rotary evaporator. Wistar rats were euthanized and the brains and livers were removed, homogenized, centrifuged and the supernatants were used for lipid peroxidation, Na+/K+-ATPase activity, and thiol assays in the presence of prooxidants (1mM H2O2 or 10μM Fe2+ or H2O2 and Fe2+).The results revealed that ethanol extract of both the leaf and stem-bark inhibited lipid peroxidation induced by H2O2, Fe2+ and combination of H2O2 and Fe2+ and this was evident in the reduction of lipid peroxidation adducts formation in rat liver and brain homogenates with the stem-bark possessing more efficacy. Furthermore, the results of  Na+/K+-ATPase and thiol assays revealed that H2O2 and Fe2+ inhibited the activity of cerebral Na+/K+-ATPase, while  H2O2/Fe2+ caused a marked reduction in the levels of both protein and non-protein thiols in the tissues homogenates. However, the ethanolic extract of Daniellia oliveri extirpated this anomaly by increasing the activity of cerebral Na+/K+-ATPase as well as the thiol level in the rat hepatic and cerebral tissues. Finally, GC-MS analysis was carried out on the ethanolic extracts of the stem bark and leaves of Daniellia oliveri and results revealed the presence of 21 compounds including 1,2-Benzisothiazol-3-amine, 1H-Indole-2-carboxylic acid, 2-Ethylacridine, Ethyl 2-(2-chloroacetamido)-3,3,3-trifluoro-2-(3-fluoroanilino) propionate and trans-1-Butyl-2-methylcyclopropane in the stem bark and 10 compounds including Methylthio-acetonitrile, 2-Methyl-Z,Z-3,13-octadecadienol, Desulphosinigrin and 4H-1,2,4-triazole-3,5-diamine in the leaves, justifying the observed biological activities of Daniellia oliveri and the higher potency of the stem bark may be attributed to the presence of more bioactive constituents found in it. This study therefore justifies the medicinal usage of leaves and stem-bark of Daniellia oliveri and suggests its consideration in the treatment and management of degeneration diseases with etiology associated with oxidative stress.","PeriodicalId":8535,"journal":{"name":"Asian Journal of Research in Biochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89439527","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}

Hence, utilization of medicinal herbs in the development and formulation of products, as an alternative to conventional drugs, is one of the method options to achieve this. \u0000Aim: This study was designed to assess the contraceptive potentials of hydro-ethanolic leaf extract of Sida acuta, through evaluating its effects on fertility hormones, pregnancy status, and body weight of female albino rats. \u0000Method: This experiment was conducted using thirty five (35) sexually matured albino rats. Using a CRD, the rats were randomly divided into five (5) groups of seven (7) rats each, with five (5) female and two (2) male replicate assigned to each group. The Control group (Group 1) did not receive any treatment. The females in the standard group (Group 2) were administerd with levonorgestrel-etinyl estradiol (standard drug) 7.5/0.75mg/kg b.w./day p.o. The females in the test groups (Groups 3, 4 and 5) were administered the plant extract at different doses of 100mg/kg b.w./day (Low dose), 200mg/kg b.w./day (Medium dose) and 400mg/kg b.w./day (High dose) p.o. respectively, for 28days. The initial and final body weights of the animals were measured. The qualitative and quantitative phytochemical analyses of hydro-ethanolic leaf extract of Sida acuta, as well as the GC-MS analysis were also performed using standard methods. Furthermore, the effects of the extract were checked on the reproductive hormones (FSH, LH, Progesterone and Estrogen), pregnancy status as well as the body weight of the animals. \u0000Results: The results revealed the presence of bioactive compounds in the hydro-ethanolic leaf extract of Sida acuta which may be responsible for the contraceptive potentials of the plant. There were decreased levels of FSH across the groups. There was no pregnancy outcome in group 5 (high-dose group). And there was a significant weight reduction in group 5 (high-dose group). \u0000Conclusion: The result suggested that the hydro-ethanolic leaf extract of Sida acuta has suppressive effects on the reproductive hormones (especially the gonadotropins) at higher dose, thereby establishing its contraceptive potentials as confirmed by the pregnancy outcome. Also, the extract is capable of significantly decreasing body weight at a high dose.","PeriodicalId":8535,"journal":{"name":"Asian Journal of Research in Biochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90429496","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}

In pregnant blood serums, zinc and copper levels were studied on fully automatic analyzers with a new method. The new technique kits used in the study are Rel Assay Diagnostics brand. The zinc ion reacted with 5-Br-PAPS and gave an absorbance at a wavelength of 548 nm in direct proportion to the total zinc level. The copper ion reacted with 3,5-DiBr-PAESA and showed absorbance at 572 nm in direct proportion to the total copper level. Zinc and copper measurements were made in this way by the colourimetric method. Additionally, copper/zinc ratios were calculated. In addition, determined the APGAR (Activity-Pulse-Grimace-Appearance-Respiration) score of the babies. Statistical studies of the obtained data were performed at p<0.05 significance level. \u0000Results: Zinc and copper parameters; No statistically significant relationship was found in the analyzes performed with gestational age, gestational week, birth weight, APGAR score, gravida and the number of living children (p>0.05).
