The purpose of this research is to evaluate the short term toxicological assessment of the Pentaclethra macrophylla (Benth) oil (oil bean seed) on organs of normal male albino rats. Fresh pods of Pentaclethra macrophylla (Benth) were collected directly from the plant tree in July 2009 at the site opposite the Bells University of Technology, Ota, Ogun State. Twenty four (24) healthy male albino rats purchased from Animal house of Department of Veterinary Pathology, University of Ibadan, and weighing between 92.0 – 105.4 g were used for the experiment. The effect of the oil extract was investigated by oral administration of the oil into different groups of rats using oral cannular (Group A-D). All the administration was carried out as single dose continually for 8 weeks. The toxicity effects of the extracted oil from Pentaclethra macrophylla (Benth) was investigated on five organs of rats (liver, brains, kidney, heart and testis). The animals were divided into four groups (A, B, C, and D) fed with a normal diet and three different levels of concentrations of the oil. With the oral cannular techniques, the first group (A) rats were fed with 0.2 ml/day of oil with a normal diet, second group (B) with 0.4 ml/day with a normal diet, the third group (C) fed with 0.6 ml/day oil with normal diet while fourth group D were treated with normal diet only, serving as the control group for the study. The results of the histological examination indicated that as the concentrations of the oil ingested increases, some of the tissues of the organs were affected. Therefore, the study suggested that Pentaclethra macrophylla (Benth) oil was toxic to the organs of the rats. Therefore, the consumption of the seeds by the human can constitute health hazards and risks.

Aim and Objective: The study was conducted to see the vascular and follicular changes induced by dexamethasone (syntheticcorticosteroid) during involution of hyperplastic thyroid gland in albino rats. Study Design: A comparative histological study done in PostGraduate Medical Institute Lahore in 1998 Procedure: 54 adult rats were taken and divided at random into two control groups having 27 ratsand experimental groups containing 27 rats. Control group was given normal diet along with 2 microgram of Potassium iodide intraperitonealyfor 21 days while experimental groups further subdivided into group A having 3 rats and group B and C containing 12 rats each. All theexperimental groups were treated with Thiourea for 21 days. Group A was sacrificed on day 22 after withdrawal of thiourea. Group B was givenPotassium iodide intraperitonealy after stoppage of TU on day 21 and were sacrificed on days 22,26,30 and 50 in 4 sub groups (B1-B4) tostudy the involution process. Group C was injected dexamethasone from 22 to 50 days after withdrawal of TU and sacrificed on same daysin 4 subgroups (C1-C4) as sub groups B. Results: The results of experimental group. A showed increase in thyroid and relative tissue weight.Histologically this group exhibited significant increase in stromal congestion with tall follicular cells lining the small sized follicles having scantycolloid. The results of experimental groups B and C demonstrated increase in thyroid and relative tissue weight but microscopically subgroupsB revealed early and complete involution whereas subgroups C showed significantly persistent hyperplastic changes in the form of stromalcongestion, vessels wall remained well defined and tall follicular cells lining small empty follicles. Conclusion: It was concluded thatdexamehasone did retain hyperplastic changes during involution evident by stromal congestion and small sized regular follicle lined by tallfollicular cells, so it should be carefully used in thyroid diseases.

The relevance of the topic under consideration lies in the need to analyze the effectiveness of short-term methods of psychotherapy to provide prompt psychotherapeutic assistance in dealing with anxiety states and reactions in employees of medical institutions, including during the period of increased stress associated with the spread of the coronavirus infection. The study was conducted on a sample of 60 medical professionals. The experimental group of 30 people was divided into two groups of 15 people (group A and group B) and a control group of 30 people. According to the results of the study, the positive effect of group methods of short-term psychotherapy on reducing the level of anxiety states and reactions in medical professionals was revealed. It was also found that the psychocorrective influence on medical professionals by means of techniques of eye movement desensitization and reprocessing was more effective than by the techniques of cognitive behavioral therapy.

Protective role of thyme extract against N-nitrosodiethylamine (NDEA)-induced oxidative stress has been evaluated in albino rats. For this, one group of rats were fed diet supplemented with thyme extract (0.5%) and served as the test group, whereas animals of the other group fed on normal diet served as the control group. The rats were fed on respective diets for a period of 2 weeks after which stress was induced to half the animals of each group by i.p. administration of NDEA at 200 mg/kg body weight. Animals were killed 48 h post stress-induction period. Feed intake and body weight decreased significantly in both test and control groups, the effect being less in test group. Increase in osmotic fragility and in-vitro lipid peroxidation (LPO) on stress induction was of lower degree in the test group. NDEA toxicity was mainly reflected in liver as evidenced by increased activities of plasma aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase. The effect was of lower degree in test group as compared with that in the control group. Increase in urea levels observed following NDEA administration was also of lower degree in test groups. Blood glutathione (GSH) levels increased more so in test group compared with control group on stress induction. The activities of superoxide dismutase (SOD), peroxidase (Px), and catalase (CAT) activities decreased significantly on stress induction in erythrocytes. LPO increased in all the tissues through varying degree, and the increase was appreciably of lower degree in test group. The activity of SOD increased significantly in both test and control group on stress induction, whereas activities of Px and CAT decreased following NDEA treatment, and the effects were of lower degree in test group. Thus, supplementation of diet with thyme extract can improve antioxygenic potential and hence help to prevent oxidative stress.

Aim: Herbs are plants or parts of plants used for their therapeutic, aromatic or savoury values. This work studied the potential sub-chronic toxic effects of Goko and BetaB, two herbal remedies used in treating human diseases and sold in Orumba Local Government Area of Anambra state, Nigeria. Design: Experimental adult Wister female albino rats were divided into five groups (A, B, C, D and E) of five animals per group. The first and second groups received 0.1 ml/kg body weight and 0.2 ml/kg body weight of Goko while the third and fourth groups received 0.1 ml/kg body weight and 0.2 ml/kg body weight of BetaB orally. The control group was given standard feed and clean drinking water only. Administration lasted for 14 days after which the animals were sacrificed by cervical dislocation and blood samples collected for biochemical assay. Results: The results of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) activity and concentration of serum total bilirubin and albumin showed varying significant (P < 0.05) differences when compared with the control. Conclusion: Result obtained from this study seems to suggest that Goko and BetaB may not be safe for use sub-chronically at high doses.

Transition metal complexes of Cu(II), Co(II) and Ni(II) with eflornithine hydrochloride hydrate (EFN), an antitrypanosomiasis drug, as ligand have been synthesized and characterized by melting point, elemental analysis, Fourier transform infrared (FTIR), electronic spectra, magnetic susceptibility and electrospray ionization mass spectrometry (ESI-MS). The FTIR spectral data suggested the coordination modes of the ligand to be bidentate, coordinated to the metal ions through its carboxylate oxygen atom and an amino nitrogen atom. From the microanalytical data, the stoichiometry of the metal complexes is 1:2 (metal to ligand). The electronic absorption and magnetic susceptibility studies generally suggested octahedral geometry for the metal complexes. Toxicological evaluation of the ligand (EFN) and complexes were carried out using albino rats. Twenty-five albino rats that were used for the experiment were randomly divided into five groups and animals in group 1 served as a control. All the animals were sacrificed twenty-four hours after completion of their doses. The results revealed a high level of toxicity of EFN than the synthesized metal complexes.                     KEY WORDS: Eflornithine hydrochloride hydrate, Carboxylate moiety, Antitrypanosomiasis drug, Toxicological evaluation, Albino rats   Bull.

Introduction: Cyclophosphamide is one of the alkylating chemotherapeutic drug used in cancer patients that has antifertility effects on female gonads. Ocimum basilicum is a natural herb rich in polyphenols and is known to improve fertility. Aims & Objectives: The study was designed to evaluate the role of natural herb, Ocimum basilicum extract, as a preventive agent against ovarian follicular toxicity induced by cyclophosphamide. Place and duration of study: This experimental study was performed in the Department of Anatomy, Shaikh Zayed Postgraduate Medical Institute, Lahore. The duration of study was 8 months. Material & Methods: 45 female albino rats were divided equally in control group A, experimental group B and group C each contained 15 rats. Group A rats received single dose of 150 mg/kg normal saline intraperitoneally on 8th day of experiment, while group B was given single intraperitoneal dose of 150 mg/kg cyclophosphamide at day 8 of experiment. Group C rats were pretreated with methanolic basil (Ocimum basilicum) seeds extract for 7 days followed by single intraperitoneal dose of 150 mg/kg cyclophosphamide at day 8 of experiment. All the rats were dissected 48 hours after the last dose. Results: Graafian follicles were atrophied showing atretic granulosa cells in group B when compared with control group A with p value <0.001. However, significant improvement in status of Graafian follicles was observed in group C, when compared with group B with p value <0.025. Conclusion: This study depicts that basil seeds extract can prevent the cellular toxicity in Graafian follicles caused by cyclophosphamide treatment. So the use of basil seeds during chemotherapy can significantly limit its toxic effects on Graafian follicles.

Aim: This study was aimed to evaluate the effect of methanol extract of Napoleonae imperialis leaves against methotrexate renal damage in albino rats. Methodology: Thirty (30) male albino rats of mean weight 130 g were used for this study. The animals for the study were grouped into five (5) of six (6) rats each. Group A (normal control) received feed and water only and Group B (positive control) was induced with methotrexate without treatment. Test groups (C and D) were orally given 250 mg and 500 mg/kg b.wt of leaves extract, and group E was orally given the extract only (500 mg/kg b.wt) respectively for 14 days. All the rats used in this study were initially subjected to renal damage using 0.5 ml/kg of methotrexate except the normal control group. The rats were sacrificed after 14 days and the blood samples were collected for biochemical analysis, Results: From the result obtained, there was a significant (p< 0.05) decrease in the groups that received 250 mg/kg and 500 mg/kg b.wt of the plant extract in (Urea, Creatinine and Na+), and a significant increase (p< 0.05) in K+ and Cl-. Also there was a significant (p< 0.05) decrease in (Urea, Creatinine, and Na+) in comparison with the control groups and the group that received the extract only (500 mg/kg b.wt), and a significant increase (p< 0.05) in (K+ and Na+). Conclusion: The study indicates that the methanol extract of Napoleonae imperialis leaves may have exerted renal functioning effects in albino rats, and may also be used pharmacologically in the management of organ toxicity.

The present study was designed to evaluate the antiurolithiatic activity of Prosopis farcta (P. farcta) ethanol fruit extract in ethylene glycol (EG) induced urolithiasis in male albino rats. Lithiasis was induced by oral administration of EG 1% in male albino rats for 28 days. Seventy eight male albino rats weighing 250-300g were used and divided into six experimental groups. Group A is a control group received standard rat chow and tap water ad libitum, while, rest of groups namely group B, C, D, E, F animals received 1% EG in water for 28 days, then from day 15 to day 28 in addition to EG administration, group C received cystone, group D, E and F received 100, 200 and 300 mg/kg body weight (B.W.) of ethanol fruit extract of P. farcta respectively. On day 28, blood was collected for serum biochemical (serum uric acid, creatinine, urea, electrolytes measurements, malondialdehyde (MDA) and superoxide dismutase (SOD)) determinations. While urine was collected to microscopic analysis of formed crystals besides the kidney weight/ B.W. ratio and B.W. gain/ loss values were determined. Intermediate dose (200mg/kg B.W.) of P. farcta extract significantly decreased serum creatinine, urea, MDA and non-significantly recovered SOD toward control value in group E as compared to group B, also significant elevation in kidney weight/ B.W. ratio and reduction in B.W. gains in group B occurred as compared with group A. In conclusion: P. farcta fruit extract has potentially therapeutic effects on EG induced kidney stone which can be used as effective antiurolithiatic agent rather than cystone.
