Anogeissus Leiocarpus

Background: This study evaluated the effects of 1:1 mixture of aqueous root bark extracts of Anogeissus leiocarpus (DC) Guill & Perr (Combretaceae) and Terminalia avicennioides Guill & Perr (Combretaceae) in male rats. Methods: Male rats were orally administered a 1:1 mixture of both extracts (250, 500 and 1000 mg/kg body weight) for seven days. Liver and kidney function indices, haematological parameters and the levels of malondialdehyde were evaluated in the animals at 7 days post-administration of the mixture of the extracts. Results: Administration of mixture of the extract significantly (p<0.05) increased the activities of liver and kidney alkaline phosphatase and reduced the serum alkaline phosphatase, liver and serum aspartate aminotransferase, alanine aminotransferase and gamma glutamyl transferase activities. The mixture also decreased the levels of serum chloride ions, liver and kidney malondialdehyde. Furthermore mixture significantly (p<0.05) increased the serum total protein concentrations whereas the levels of serum albumin, creatinine, urea, potassium, sodium and bicarbonate ions, red blood cells, white blood cells and their related indices were not significantly (p>0.05) altered. Conclusions: The present study revealed that the mixture caused functional toxicity of the liver and kidney of male rats without any evidence of haematotoxicity. The consumption of the 1:1 mixture of the plant extracts at 250, 500 and 1000 mg/kg body weight has some toxic implications in male rats.

The aqueous extract of the leaves of Leonotis leonurus (L.) R. Br. at the doses of 125, 250 and 500 mg/kg body weight was investigated for toxicity in male rats following administration on daily basis for 21 days. The extract did not significantly (p > .05) alter the levels of haemoglobin, packed cell volume, mean corpuscular volume, red cell distribution width, basophils, total protein, phosphorus, calcium and chloride ions of the animals. Whereas the levels of lymphocytes, eosinophils, monocytes, triacylglycerol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, atherogenic index, albumin as well as alkaline phosphatase and gamma glutamyl transferase activity were decreased by the extract, those of neutrophil, magnesium, total and conjugated bilirubin, alanine and aspartate aminotransferase as well as liver and kidney body weight ratios increased. There was decrease in the mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration and cholesterol only at the 500 mg/kg body weight of the extract, whereas the large unstained cells, sodium ions, white blood cells and uric acid increased only at 250 and 500 mg/kg body weight of the extract, respectively. The urea, creatinine and potassium increased only at 125 mg/kg body weight of the extract while the globulin content was elevated only at 500 mg/kg body weight of the extract. The doses did not produce any definite pattern of effect on the red blood cells and platelets. These alterations by the aqueous extract of L. leonurus leaves on the haematological together with the liver and kidney functional indices suggests parameter and dose-selective effects of the extract and will have consequential effects on the normal functioning of the blood system, kidney and liver of the animals. The extract is also unlikely to predispose the animals to cardiovascular risk when repeatedly consumed on daily basis at the doses investigated for 21 days. Therefore, the aqueous extract of L. leonurus leaves may not be ‘safe’ as oral remedy in male rats.

The mode of cellular toxicity of aqueous extract of Fadogia agrestis stem in male rats was investigated. Rats were grouped into four: A, B, C and D where A (the control) received orally 1 mL of distilled water; B, C and D (test groups) received orally 18, 50 and 100 mg/kg body weight of the extract, respectively, for 28 days. Infrared spectroscopy indicated the presence of hydroxyl (OH) and primary amine (CONH). Clinical toxicity symptoms such as respiratory distress, epistasis, salivation, hypo- and hyperactivity were not observed at any period of the experiment. No mortality was also recorded. Extract administration significantly reduced (p < .05) the activities of alkaline phosphatase, lactate dehydrogenase and gamma glutamyl transferase in the liver and kidney with corresponding increases in the serum. Serum malondialdehyde also increased significantly in all the extract-treated groups. The liver and kidney body weight ratios of the extract-treated animals compared well (P > .05) with their controls throughout the experimental period. The extract did not cause any swelling, atrophy or hypertrophy of the organs. The other evidence in this study suggests disruption of the ordered lipid bilayer of the plasma membranes of the hepatocytes and nephrons. This might have resulted from peroxidation of the polyunsaturated fatty acids on the membranes of the hepatocytes and nephrons made possible by the functional groups or the product of metabolism of the extract. This may be responsible for the compromise of the integrity of the plasma membranes of the hepatocytes and nephrons.

Background: This study investigated the protective effects of aqueous extracts of Anogeissus leiocarpus (DC) Guill & Perr (Combretaceae) and Terminalia avicennioides Guill & Perr (Combretaceae) root barks, as well as their 1:1 (w/w) mixture on liver redox and haematological parameters of diethylnitrosamine-treated rats. Methods: Rats were orally administered distilled water, diethylnitrosamine (30 mg/kg body weight once a week on weeks 3 and 4), curcumin (200 mg/kg body weight), extracts and 1:1 mixture (200, 400 and 800 mg/kg body weight) for 4 weeks. Malondialdehyde, markers of oxidative stress and hematological indices were evaluated. Results: The extracts and their mixture significantly (P<0.05) reversed the diethylnitrosamine-induced alterations in the levels of liver malondialdehyde, superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glucose 6-phosphate dehydrogenase, glutathione, vitamin C and platelet counts. The other haematological parameters (red blood cell count, haemoglobin concentration, packed cell volume, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, white blood cell count, lymphocyte count and neutrophil count) were not affected by diethylnitrosamine and extracts. Conclusion: The extracts possess antioxidant, hepatoprotective and haemoprotective activities that compared well with curcumin. These activities were better exhibited by the mixture than the individual extracts.

Aloe ferox Mill. is a widely used medicinal plant in South Africa for the treatment of many ailments including constipation. The present study evaluated the toxicological effect of aqueous leaf extract of the herb at 50, 100 and 200 mg/kg body weight for 7 days on the haematological parameters as well as liver and kidney function indices in loperamide—induced constipated rats. The extract did not cause any significant (p > 0.05) effect on the kidney and liver—body weight ratio as well as the kidney function indices including serum levels of creatinine, uric acid, urea, calcium and potassium ions at all the dosages investigated. Whereas the serum levels of total protein, albumin, bilirubin and gamma glutamyl trasferase (GGT) were not affected, the elevated activities of alkaline phosphatase (ALP), alanine transaminase (ALT) and aspartate transaminase (AST) in the untreated constipated animals were normalized following treatment with extract. The data obtained with respect to the haematological analysis indicated that the extracts had no significant (p > 0.05) effect on the haematological parameters with the exception of lymphocyte count which was increased in the untreated constipated rats. This was however attenuated after administering the herb. The available evidence in this study suggests that A. ferox may be safe as an oral remedy for constipation. Generally, the effect of the extract compared favourably well with senokot, a recommended drug for the treatment of constipation.

Malaria, a hazardous infirmity caused by a parasitic malady of the red blood cells, is without question harming to the wellbeing. In the present investigation, the chemosuppresive and haematopoietic activities of 200 mg/kg and 400 mg/kg body weight of unrefined ethanolic concentrates of three Chinese green teas (BIA 849, TD 570 and GB/T19598) were assessed using the 4-day suppressive anti-plasmodial assay in mice Plasmodium berghei (NK65 strain) pre-infected mice. The effect of the extracts on weight of the animals was evaluated. It was observed that 200 mg/kg bw (body weight) of BIA 849 and GB/T19598 were as potent as 5 mg/kg bw of chloroquine, with percentage suppressions of 58.97 ± 5.04, 57.63 ± 5.62 and 57.50 ± 4.5, respectively. TD570 at 200 mg/kg bw was more effective in suppressing plasmodium. 400 mg/kg body weight of TD570 and GB/T19598 extracts were more potent than 5 mg/kg bw of chloroquine having 100 % chemosuppression. The chemosuppression of BIA 849 did not change altogether at 400 mg/kg bw. The haematological parameters, WBC, RBC and MCV did not significantly change in the groups treated with the tea extracts utilizing suppressive model of malaria treatment contrasted with the uninfected group and were comparable to those treated with chloroquine. Haemoglobin concentration nonetheless, varied significantly with respect to the uninfected group. Weight changes were most significant with 200 mg/kg bw of TD 570 treated group (32 % increase) on suppression. All in all, the green teas displayed high chemosuppressive and haematopoietic possibilities and are thusly prescribed as contender for additionally screening as elective antimalarial drugs

Введение. Изменение реологических свойств крови характерно для различных заболеваний, многие из которых связаны с нарушением реологии и, прежде всего, с изменением агрегации эритроцитов. Целью исследования было сравнение влияния малых регуляторных пептидов, являющихся фрагментами нейрогормонов, на агрегацию эритроцитов и тромбоцитов под действием адреналина в экспериментах in vitro. Материалы и методы. Эксперименты проводили на белых беспородных крысах-самцах, массой тела 180-200 г. Использовали пептиды, представляющие собой С-концевые фрагменты вазопрессина (Pro-Arg-Gly-NH2) и окситоцина (Pro-Leu-Gly-NH2). Результаты. Показано, что малые регуляторные пептиды, являющиеся продуктами протеолиза нейропептидов, оказывают существенное влияние на агрегатное состояние клеток крови. При сравнении влияния пептидов на агрегацию клеток крови, стимулированную адреналином, установлено, что фрагмент вазопрессина Pro-Arg-Gly-NH2 вызывал достоверное усиление агрегации как эритроцитов, так и тромбоцитов; тогда как фрагмент окситоцина Pro-Leu-Gly-NH2 ингибировал только агрегацию эритроцитов, не изменяя агрегации тромбоцитов. Заключение. Изучение путей поэтапного протеолиза пептидов может привести к разработке новых препаратов для направленной коррекции различных нарушений в организме, поэтому изучение эффектов С-концевых фрагментов гипофизарных гормонов на гемостаз является актуальным. Introduction. The changing of blood rheological properties is typical for various diseases; many of them are associated with rheology disorder and primarily with change of erythrocytes aggregation. The aim was to compare the effect of small regulatory peptides (fragments of neurohormones) on the aggregation of erythrocytes and platelets under adrenaline action in experiments in vitro. Materials and methods. Experiments were conducted on white outbred male rats, body weight 180-200 g. We used 2 peptides – C-terminal fragments of vasopressin (Pro-Arg-Gly-NH2) and oxytocin (Pro-Leu-Gly-NH2). Results. It was shown that small regulatory peptides (they are products of neuropeptides proteolysis) had a significant effect on blood cells aggregation. We compared the peptides effect on blood cells aggregation stimulated by adrenaline. It was found that vasopressin fragment Pro-Arg-Gly-NH2 significantly increased both erythrocytes and platelets aggregation, while oxytocin fragment Pro-Leu-Gly-NH2 inhibited only erythrocytes aggregation without changing of platelet aggregation. Conclusion. Investigation of phased peptides proteolysis may result in the development of new drugs for targeted correction of various disturbances. So it is of current interest to study the effects of C-terminal fragments of pituitary hormones on hemostasis.

Abstract Considering that the involvement of reactive oxygen species (ROS) has been implicated in the toxicity of various pesticides, this study was designed to study the ameliorative effect of Vitamin E (100 mg/kg body weight) on mice (25 - 30 mg) treated with diazinon (32.5 or 16.25 mg/kg body weight) organophosphate insecticide for 14 days. Subchronic DZN exposure and the protective effects of vitamins E (vitE) were evaluated for their effects on haematological indices, the enzymes concerning liver damage [plasma alanine aminotransferase (ALT), aspartate aminotaransferase (AST), alkaline phosphatise (AIP), and some parameters of kidney function (urea and creatinine) in mice. Additionally, the histopathological changes in liver and kidney tissue were examined. The high dose of diazinon (DZNH) decreased the body weight significantly at the end of experiment. Additionally, the liver and kidney were examines for histopathological changes. The high dose of diazinon decreased body weight significantly. Moreover, there was a statistically significant decrease in haemoglobin (Hb), red blood cell (RBC) and hematocrit (Hct) in diazinon-treated mice compared to controls. This decrease was partially remedied in the diazinon-treated group that also received vitE. Damage in the liver and kidney tissues was also evident as elevated plasma ALT, AST, ALP, urea and creatinine. VitE partially counteracts the toxic effect of DZN and repairs tissue damage in the liver and kidney, especially when supplemented to 1/4 LD50 intoxicated animals. Histopathological changes in liver and kidney were observed only in 32.5 mg/kg DZN given group. These results suggest that the effects of DZN are dose dependent. No pathological findings were observed in vitE + DZN treated groups. According to the present study, we conclude that vitE can reduce the detrimental impacts of diazinon on haematological indicies, as well as liver and kidney function.

A comparison was made of the morphological effects of cold, heat and simulated altitude on adult male rats given exposures of 24 weeks' duration. By the use of covariance analysis it was possible to determine the extent to which organ weights were dependent upon body weight and to adjust the values in order to remove body weight influences. For liver, heart and kidney, adjusted weights indicated temperature-dependency, while pressure-dependency was established for liver and kidney only. Histologically, temperature-dependency was indicated for liver, kidney, thyroid, adrenal and pituitary. Fur weight was reduced in heat but not altered in cold. Fasting in cold induced changes in adrenal and thymus weight and unusually high body weight loss; in heat, fasting caused a significant thymus weight loss without adrenal weight increase. The thymus-adrenal ratio was elevated during a 24-hour fast in all environments except cold, where it was decreased.

The mechanism underlying the reduced Cu status in rats fed on a high-Sn diet was investigated. Male rats aged 4 weeks were fed ad lib. on purified diets containing either 1 or 100 mg Sn/kg and demineralized water for a period of 4 weeks. The high-Sn diet had no effect on feed intake, body-weight gain or weight of liver and kidney but significantly reduced Cu concentrations in plasma, liver and kidney. Biliary Cu excretion was decreased significantly in rats fed on the high-Sn diet. Apparent Cu absorption (Cu intake−faecal Cu) was not affected by the high-Sn diet, but the estimate of true Cu absorption (Cu intake−(faecal Cu−biliary Cu)) was significantly reduced. We conclude that high Sn intake reduces Cu status in rats through inhibition of Cu absorption. The decreased biliary Cu excretion observed on the high-Sn diet is a result of the reduced Cu absorption.

This study aimed to investigate the prophylactic effect of turmeric (Curcuma longa) Rhizome Ethanolic extract (CLRE) at 250 mg/kg as antioxidant effects against penconazole induced sub-acute toxicity. Hepatic, renal and testicular pathological changes caused by oxidative damage induced by penconazole in rats were biochemically and histologically evaluated. Male rats were treated with penconazole, via oral route, at doses of 0.5 mg/ kg body weight (b.w.; acute reference dose, ARfD), 25 mg/kg b.w. (no observed adverse effects level, NOAEL) and 100 mg/ kg b.w. (1/20 lethal dose [LD50]) for 28 consecutive days. Penconazole treatments had significant (p < 0.05) and gradual reductions in body and relative testicular weight accompanied by significant elevation in the relative liver and kidney weights. Significant increase serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dhydrogenase(LDH), gamma-glutamyl transferase (GGT), creatinine (Cre), uric acid and blood glucose was observed due to penconazole treatments. However, total protein and testosterone hormone were significantly decreased. Exposure to penconazole caused increase in lipid peroxidation (LPO) and decreased of liver and kidney antioxidant enzymes activity as catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx). Histopathological studies confirmed the ameliorative beneficial effects of turmeric biochemical parameters. On the basis of this study, the use of tumeric rhizomes as a functional food or as a nutraceutical product could be a useful approach to protect individuals who are regularly exposed to penconazole.
