EFEKTIVITAS EKSTRAK ETANOL KULIT TERONG UNGU (Solanum melongena L.) SEBAGAI ANTIMALARIA TERHADAP JUMLAH BASOFIL DARAH MENCIT (Mus musculus) YANG DIINDUKSI Plasmodium berghei

Malaria is one of the disease which spreads through the bite of female Anopheles mosquito caused by Plasmodium parasite. Malaria can be treated with antimalarial drugs such as chloroquine and artemisin, but in some malaria-endemic areas, parasitic resistance to chloroquine has been reported so that malaria eradication becomes increasingly difficult. The occurrence of such resistance causes the need for new antimalarial findings. Eggplant (Solanum melongena L.) has many secondary metabolites, such as alkaloids, terpenoids, and flavonoids which have antiplasmodial activity. The aim of this research is to determine the effectivity of the ethanol extract of eggplant peels as an antimalarial to basophil in mice induced by Plasmodium berghei. Eggplant peel was extracted by maceration method using 70% ethanol. The analysis of secondary metabolites from the ethanol extract of eggplant peels used tube test and thin layer chromatography. The level of parasitemia and the number of basophil were calculated from blood smear of mice (Mus musculus) which were treated with extracts at a dose of 0.075 mg/20 g of body weight; 0.15 mg/20 of body weight; and 0.3 mg/20 g of body weight. 3.744 mg/20 g of body weight DHP was used as positive control and aquades was used as negative control. Research result show that ethanol extract of the eggplant peels contains groups of alkaloids, flavonoids, terpenoids, steroids, phenolic and saponins. 0.075 mg/20 g body weight of ethanol extract of the eggplant peels effectively reduces parasitemia. Ethanol extract of the eggplant peels in all dose groups did not have an effect on basophils. The conclusion of this research is ethanol extract of the eggplant peels has antimalarial activity and does not increase the number of basophils.

Antioxidant potential of ethanol extract of Annona muricata leaves and its inhibitory effect on lipid peroxidation in 1,2-dimethylhydrazine induced colon carcinogenesis

Annona muricata, as it is scientifically called but known in most parts of Nigeria as soursop. A fruit tree with various therapeutic uses, the plant belongs to the family of Annonaceae and has several medicinal properties. The medicinal properties of Annona muricata are well known, and they can be used to treat a variety of illnesses and conditions. Effects of ethanol extract of Annona muricata leaves (EEAML) on the enzymatic antioxidants of the kidney and colon in Wistar rats induced with 1, 2 Dimethylhydrazine (DMH) at 25 mg/kg bodyweight s.c. were investigated in this study. Thirty-six male Wistar rats weighing 110–170g were acclimated for two weeks and randomized into six groups (six per group). Group A (control), Group B (extract; 120 mg/kg body weight of ethanolic extract of A. muricata), Group C (DMH only), Group D (DMH + EXTRACT), Group E (pretreatment), and Group F (posttreatment). The extract was administered daily via oral gavage, while the DMH was given subcutaneously at a dosage of 25 mg/kg bodyweight. This study reveals the carcinogenic effect of DMH induced oxidative stress were ameliorated by the administration of this leaf extract of EEAML at a dose of 120mg/kg b.w. The colon and kidney homogenates of rats administered EEAML (co-treated, pretreatment and post- treatment) showed increased enzymatic antioxidant; glutathione peroxidase, catalase activities and SOD activities. But a reduction in malondialdehyde levels was observed. These findings validate the use of Annona muricata in traditional medicine by showing that the ethanolic extract of the leaves can reduce DMH-induced oxidative stress and alter the enzymatic antioxidant profile in colon carcinogenesis.

The histology of the testicular tissue shows markedly shrunken seminiferous tubules with severe germ cell aplasia and basement membrane thickening following cyclophosphamide administration which was restored to normal after treatment with aqueous extract of Annona muricata. Conclusion: The study reveals that Annona muricata possess protective effect against cyclophosphamide-induced reproductive toxicity in male wistar rats.

Antihyperlipidemic property of Murraya koenigii ethanolic leaf extract on lipid profile of rats fed with cholesterol-enriched diets.

This study was designed to investigate the effect of orally administered ethanolic leaf extract of Murraya koenigii on lipid profile of rats fed with cholesterol-enriched diets for 14 days. The study was carried out on 20 male wistar rats divided into 4 groups (n=5). All animals were given ad libitum access to drinking water. Group A was the control group and received normal rat chow, group B received cholesterol-enriched diet (CED); while group C and D received cholesterol-enriched diet and were treated with 200mg and 400mg/kg body weight of ethanolic extract of Murraya koenigii leaf respectively. Blood samples were collected by cardiac puncture on the last day of the experiment for biochemical analysis. Lipid profile was determined by Colorimetric method. Data were expressed as mean ± SEM. Differences in means were compared using ANOVA and Students T-test, P-values ≤ 0.05 were taken as statistically significant. Results showed a significant increase (p ≤ 0.05) in Total cholesterol (TC) level (117.4 ± 4.6) and low density lipoprotein cholesterol (LDL-c) level (50.1 ± 4.7) of group B rats when compared to other groups. The MK (400 mg/kg) treated rats, showed a significant reduction in TC and LDL-c levels, and a significant increase in HDL-c level when compared to CED group. However, there were no significant changes in all the lipid parameters of the treated groups when compared to the control. This study shows that cholesterol-enriched diet causes dyslipidemia and Murraya koenigii exhibited significant hypolipidemic effect on serum TC and LDL-c and increases HDL-c. Hence, Murraya koenigii exhibit antihyperlipidemic properties. Keywords: Murraya Koenigii, hyperlipidemia, Lipid profile, Cholesterol-enriched diet.

The Evaluation of Biochemical Parameters of Ethanolic Extract of Lepidium meyenii in Male Wistar Rats

he effects of ethanolic extract of Lepidium meyenii on some biochemical parameters were investigated with the purpose of in vivo safety evaluation of the extract. Forty male Wistar rats were grouped into five groups of eight animals each. Group A served as the control and received distilled water throughout the period of administration while groups B, C, D, and E received 25, 50, 75, and 100 mg/kg body weight of ethanolic extract of L. meyenii respectively for seven and fourteen days. After seven days of the administration, four animals from each of the groups were sacrificed and the rest were sacrificed after fourteen days, and biochemical alterations were monitored. The effects after the seven-day administration revealed that there was no significant (p > 0.05) difference in organ-body weight percentage, liver functional indices, kidney functional indices and the activity of some cytosolic and membrane-bound enzymes studied but following the fourteen-day administration, a significant difference (p < 0.05) were observed with increase in organ-body weight percentage of selected organs, increase in serum activity of the enzymes: ALT, AST, ALP; and aberrant variation in the kidney functional indices studied at the 50, 75 and 100 mg/kg body weight showing selective toxicity of the extract. Inconclusive results were obtained in the analysis of the seminal parameters for both the seven- and fourteen-day administration while similar effects on hematological parameters were observed for both the sevenand fourteen-day administration. This study showed that the extract may be hepatotoxic and nephrotoxic when administered beyond seven days in male Wistar rats especially at 100 mg/kg body weight. Keywords: Cytosolic, Haematology, Hepatotoxic, Membrane, Nephrotoxic

Effects of ethanol extracts of Diodia sarmentosa leaves on biochemical and histopathological indices of monosodium glutamate-induced uterine leiomyoma in rats

Background: Diodia sarmentosa leaves have gained application in the local treatment of certain ailments. This study evaluated the effect of ethanol extracts of Diodia sarmentosa leaves on biochemical, antioxidant, and histopathological indices of monosodium glutamate-induced uterine leiomyoma in albino rats. Methods: Twenty-one (21) female adult albino rats were acclimatized for 10 days and then classified into three treatment groups, each containing seven rats. Group 1 was the normal control (NC) without any induction, Group 2 was the positive control (PC) and was induced with 200 mg/kg body weight of monosodium glutamate (MSG) without treatment, and Group 3 was the treated group (TG), induced with 200 mg/kg body weight of MSG, then treated with 400 mg/kg body weight of ethanol extract of Diodia sarmentosa leaves for 30 days. Results: The results of the study showed an impaired antioxidant system in the positive control (untreated group). Some biochemical parameters were also altered in the positive control, mostly revealing a relationship between uterine leiomyoma and renal impairment, or kidney damage. Treatment with ethanol extracts of Diodia sarmentosa leaves significantly (P < 0.05) improved the altered biochemical and antioxidant parameters. These findings were also supported by a histopathology result, which revealed the extent of tumors in the affected tissues. Conclusion: The ethanol extract of Diodia sarmentosa (Sw) leaves mitigated oxidative stress and improved the impaired antioxidant system caused by uterine leiomyoma induction.

Neuroprotective Effect of Ethanolic Extract of Portulaca quadrifida L. in Rotenone-Induced Locomotor Impairment in Drosophila Model and Haloperidol-Induced Catalepsy Rat Model

The neurodegenerative diseases are characterized by the depletion of neuronal physiology and death as a virtue of potential oxidative stress. Parkinson’s disease is a one of the debilitating neurodegenerative disease wherein the depletion of dopaminergic neurons results mainly in motor dysfunction. The present study was focused to study the neuroprotective effect of ethanolic extract of Portulaca quadrifida L. (Portulacaceae) against Parkinson’s like symptoms. The experimental designs included were rotenoneinduced locomotor impairment in Drosophila model and haloperidol-induced catalepsy in rat model; both resembling the motor dysfunction observed clinically in Parkinson’s disease. The behavioral parameters were evaluated. Additionally the biochemical parameters of oxidative stress markers were evaluated in haloperidol-induced catalepsy in rat model. The locomotor behavior of rotenone-exposed Drosophila was improved significantly (p<0.05) when treated with 1 and 2 mg/ml doses of ethanolic extract of Portulaca quadrifida. The behavioral response of the catalepsy induced experimental rats (disease control group) was significantly (p<0.05) lower than that of vehicle control and standard control group. The co-exposed rats with haloperidol showed marked improvement at doses 100 and 200 mg/kg body weight of ethanolic extract of Portulaca quadrifida. The significant improvement in biochemical parameters further confirmed the antioxidant efficacy of ethanolic extract of Portulaca quadrifida. The standard drug used was Zandu Zandopa powder. Thus the study reveals that the ethanolic extract of Portulaca quadrifida imparts neuroprotective effect against motor dysfunction and hence has the potential to be used in the treatment of Parkinson’s disease.

Pharmacognostic and antidysentery screening of mixed ethanol leaf extract of Parkia biglobosa and Acanthus montanus (50:50)

Introduction: Parkia biglobosa belong to the family mimosaceae and Acanthus montanus belong to the family acanthaceae. The plants both have a multipurpose use as herbal medicine. Aim: This work investigate the pharmacognostic standard and anti-dysentery activity of the mixed ethanol extract of both plants on E. histolytical induced dysentery. Method: The phytochemical, chemo microscopy and proximate analysis were carried out using the standard procedures. The mixed extract of ratio 50:50 was administered to different groups of rats at different doses. Loperamide was administered as standard drug. The change in faecal consistency was observed and recorded. Result: The phytochemical analysis shows the presence of alkaloids, tannins, proteins, glycosides and carbohydrates. Chemomicroscopy of both plants showed the presence of starch, calcium oxalate, lignin, cellulose. While the extractive value analysis gave 25.0% and 32.7% for water extractive value and ethanol extractive value respectively (for Acanthus montanus) and 23.0% and 30.0% for water extractive value and ethanol extractive value respectively (for Parkiabiglobosa). The absence of death at 5000mg/kg of the extract shows that the lethal dose of the ethanol extract of the plant mixture is higher than 5000mg/kg which may be an indication of safety of the mixture. The anti-dysentery activity of the mixture of both plants with different concentration of 250mg/kg, 500mg/kg, 1000mg/kg body weight of ethanol extract showed a significant change in the faecal consistency of the rats. The effect obtained on the administration of 500mg/kg body weight of the extract mixture is more comparable to the standard (loperamide). Conclusion: The synergistic use of the extract contains the secondary metabolites glycosides, alkaloids, flavonoids, which may be responsible for their anti-dysentery synergistic activity. Mixed extracts from both leaves of P. biglobosa and A. montanus can be recommended as an anti-dysentery agent.

Aluminum Chloride-Induced Oxidative Damage to Serum and Combined Intervention of Ascorbic Acids and Massularia Acuminata On Selected Markers Of In Vivo Antioxidant Enzymes in Wistar Rats

This study evaluates the synergistic antioxidants effects of extracts of Massularia acuminata and ascorbic acid in aluminum chloride-treated oxidative stress in wistar albino rats with a view to investigate the preventive potential of co-administration of Massularia acuminata and ascorbic acids. The in vivo antioxidant properties of the extract were evaluated using in vivo catalase activity, superoxide dismutase activity and thiobarbituric acid reactive substances assay by standard methods via spectrophotometry. The in vivo studies were carried out on rats, grouped majorly into positive control, negative control and the treated groups. The positive control group was administered with normal saline (distilled water) orally, while the negative control group was orally induced with the toxicant (aluminium chloride). The treated group was orally administered with the extract after toxicant administration. Ascorbic acid was used as standard antioxidant in the study. The effects on enzymatic antioxidants and lipid indices were evaluated. Forty healthy Wistar rats sub-grouped into ten (10) groups were induced with aluminum chloride. Some rats were treated with ascorbic acid which is a well-known antioxidant, while others were treated with various extracts of Massularia acuminata (Pako Ijebu) at various doses. The experiment is designed as follows: in Group 1, animals were used as control group. Animals in Group 2 were the toxicant-treated groups administered with AlCl3 (34 mg/kg body weight). Ascorbic acid treated groups are the standard control (group 3) administered with 200 mg/kg body weight. Animals in Group 4 were co-treated with AlCl3 and Ascorbic acid (34 mg/kg aluminum chloride and 200 mg/kg body weight of ascorbic acid). Animals in group 5 were co-administered with ethanolic extract (50 mg/kg body weight) of Massularia acuminata and AlCl3 (34 mg/kg body weight), respectively. Animals in group 6 were also co-treated and administered with ethanolic extract of Massularia acuminate (100 mg/kg body weight) and AlCl3, respectively. Experimental animals in group 7 were equally co-administered with methanolic extract of Massularia acuminate (50 mg/kg body weight) and AlCl3, respectively. Animals in group 8 were co-administered with methanolic extract of Massularia acuminate (100 mg/kg body weight) and AlCl3, respectively. Group 9 animals were co-administered with butanolic extracts of Massularia acuminata (50 mg/kg body weight) and AlCl3, respectively. Group 10 experimental animals were also co-administered with butanolic extract of Massularia acuminate (100 mg/kg body weight) and AlCl3, respectively. At the end of the experiment, the animal was sacrificed after three weeks by cervical dislocation after they were immobilized using chloroform. Results show that ethanolic and methanolic extracts of Massularia acuminata contain antioxidant properties. Both doses of ethanolic extract dose (50 mg/kg and 100 mg/kg body weight) group of methanol extract also reduced the level of MDA but not as ascorbic acid group. Both doses of methanolic extract of Masssularia acuminata act contrariwise from other extracts in that they show the highest level of malonaldehyde even more than AlCl3. The results of superoxide dismutase (SOD) assay test in this study show that the control group, ascorbic acid combined with AlCl3 group, 50 mg/kg body weight of ethanolic extract. Both doses of methanolic extract groups have the same comparative value of SOD. The group treated with toxicant (aluminum chloride) and ascorbic group has similar relative value. The group treated with 50 mg/kg body weight of butanolic extract shows the highest value of superoxide dismutase activity that follow closely by 100 mg/kg of ethanolic extract group. The study concluded that Massularia acuminata, like ascorbic acids, can induced antioxidant enzymes such as SOD and CAT in aluminium chloride-induced oxidative stressed rats. It may therefore be used to protect the body against any pathological attacks from free radical and oxidative insults.

Objective: To investigate the impact of ethanol extract of Spondias (S.) mombin leaves on the biochemical parameters of testicular function, hormonal profile, sperm profile and reproductive outcomes of guinea pigs. Methods: Sexually matured male [(1000.40±8.12) g] and female [(810.00±7.09) g] guinea pigs were used. In testicular function study, a total of 24 male guinea pigs were randomised into 4 groups of 6 guinea pigs each. Group A (control) were orally administered 1 mL of physiological saline, once daily for 60 days while groups B, C and D were treated like the control group except that they were orally administered 100, 250 and 500 mg/kg body weight of ethanol extract of S. mombin leaves. For the fertility study, the same animal groupings and treatments in the testicular function study were adopted. The male guinea pigs were paired with the females (1:1) and afterwards examined for pregnancy outcomes. Results: The ethanol extract of S. mombin leaves contained saponins, alkaloids, flavonoids, tannins, steroids, phenolics, phlobatannins, cardiac glycosides, cardenolides and dienolides with saponins (4.80 mg/mL) occurring the most whilst cardenolides and dienolides (0.08 mg/mL) were the least. The ethanol extract of S. mombin leaves significantly and dose dependently reduced the activities of alkaline phosphatase, glutamate dehydrogenase, 3-hydroxy-3-methylglutaryl coenzyme A reductase, malic enzyme, 17-β-hydroxysteroid dehydrogenase, lactate dehydrogenase, catalase and superoxide dismutase as well as levels of testosterone, glycogen, total protein and ascorbic acid in the testes when compared with the control group (P 0.05). The ethanol extract of S. mombin leaves at both 100 and 250 mg/kg body weight significantly reduced the total number, circumference, weight and length of the pups whereas the 500 mg/kg body weight of ethanol extract of S. mombin leaves-treated rats did not produce any pup. The 250 and 500 mg/kg body weight of ethanol extract of S. mombin leaves induced degenerative and necrotic changes in the seminiferous tubules with vacuoles in the germinal epithelium and a few to complete absence of spermatozoa. In all of these, the 500 mg/kg body weight of ethanol extract of S. mombin leaves produced the most pronounced alteration on the parameters. Conclusions: S. mombin leaves have induced infertility in the male guinea pigs via endocrine dysregulation, anti-spermatogenic activity, testicular dysfunction and oxidative stress and made possible by the presence of saponins, alkaloids, flavonoids, tannins, steroids, phenolics, and cardiac glycosides.

Colon cancer was evaluated by the formation of Aberrant Cryptic Foci in the colon of DMH treated mice.&#x0D; Results: Administration of the plant extracts (aqueous and ethanolic) ameliorated the carcinogenic effect of DMH in the colon of DMH treated mice in a dose dependent manner by significantly reducing the number of Aberrant Cryptic Foci formed in extract treated mice by 38% for 350 mg/kg body of ethanolic extract and by 22% for 350 mg/kg body of aqueous extract of Phyllanthus amarus.&#x0D; Conclusion: The studied extracts had ameliorative potential on DMH induced colon cancer in Balb/C mice in a dose dependent manner providing evidence for the traditional use of this herb for treatment/prevention of cancer. Notably, 350 mg/kg body of both extracts showed better reduction of Aberrant Cryptic Foci compared to 250 mg/kg body of both ethanolic and aqueous extracts of Phyllanthus amarus.

Anti-anaemic effect of ethanol leaf extract of Cnidosculus aconitifolius on cyclophosphomide-induced anaemia in rats.

The folkloric claim that Cnidoscolus aconitifolius (Chaya) could ameliorate anaemia requires scientific revalidation in anaemic models. The aim of this study is to investigate the anti-anaemic effect of Cnidoscolus aconitifolius on cyclophosphamide-induced anaemia in rats. The leaves of Cnidoscolus aconitifolius were collected, dried and extracted with ethanol. Twenty five Wistar Albino rats weighing 120-180kg were used. Anaemia was induced in groups 2, 3, 4 and 5 with a single injection of cyclophosphamide, while group 1 served as a negative control without anemia and was treated with 0.5mL of normal saline, Group 2 rats were treated with 100mg/kg body weight of Cnidoscolus aconitifolius. Group 3 rats were treated with 500mg/kg body weight of Cnidoscolus aconitifolius. Group 4 served as the positive control rats and was treated with 0.5mL of normal saline. Group 5 which served as the standard control rats and were treated with 5mg/kg body weight of standard drug Chemiron. The treated lasted for two weeks during which blood samples were collected from each rat for haematological analysis. The result shows that hematological parameterswere elevated in groups 2, 3 and 5 rats treated with100mg/kg and 500mg/kg body weight of ethanol extract of Cnidoscolus aconitifolius and chemiron respectively. Ethanol leaf extract of Cnidoscolus aconitifolius at a graded dose of 500mg/kg body weight had higher ameliorative effect on the haematological parameters of cyclophosphamide-induced anemia in rats.

Effect of ethanol extract of Telfairia occidentalis leaf on some biochemical parameters of 2,4-dinitrophenyl hydrazine induced oxidative stress in albino rats

Abstract In this study, we attempt to verify the claim that the leaf-extract of Telfairia occidentalis can remedy oxidative damage condition as well as assess its phytochemical content. Fifteen male albino rats weighing 180 g to 240 g were randomly divided into three groups of five rats each. Group A was designated the control group while group B and C were both induced with 40 mg/kg body weight 2,4-dinitrophenyl hydrazine. Group C was subsequently treated with 200 mg/kg body weight of ethanol extract of T. occidentalis leaf for 21 days. At the end of the treatment, the animals were sacrificed, and serum of the samples were subjected to relevant tests. Result shows that the plant leaf contained saponin, tannins, alkaloids, flavonoids and phenols whereas, terpenes, steroids and anthraquinones were not detected. The serum enzymes alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were significantly elevated from 17.43 u/L and 28.40 u/L to 21.60 u/L and 34.27 u/L respectively. These were significantly lowered in the group C to 18.37 u/L and 29.23 u/L respectively for ALT and ALP. Also, a significant lowering of superoxide dismutase (SOD) activity was observed in the treated group (54.33 u/mg) from 79.40 u/mg recorded in the intoxicated group. Similarly, a significant decrease in malondialdehyde was observed in the treated group (25.80 u/mg) relative to the intoxicated group (35.87 u/mg). Moreover, catalase activity in the treated group (7.43 u/mg) was significantly lower compared with the intoxicated group. Our observation confirmed that ethanolic leaf extract of T. occidentalis reversed the oxidative damage condition in albino rats. The result confirms the ethnomedicinal use of the plant in the management of oxidative stress related diseases.

THE EFFECTIVITY OF THE ETHANOL EXTRACT OF EGGPLANT (SOLANUM MELONGENA L.) PEELS AS ANTIMALARIAL TO MONOCYTE IN MICE (MUS MUSCULUS) INDUCED BY PLASMODIUM BERGHEI

Malaria is a disease caused by Plasmodium that is transmitted to humans by the bite of the female Anopheles mosquito. Malaria can be treated with antimalarial drugs such as chloroquine and artemisinin, but in some endemic areas, it is reported that parasitic resistance to chloroquine was reported so that malaria eradication becomes increasingly difficult. The occurrence of this resistance causes the need for new antimalarial findings. Eggplant (Solanum melongena L.) has many secondary metabolites, one of which is solanidine which is toxic to bacteria, fungi, viruses, and protozoa. Eggplant peel was extracted by maceration method using 70% ethanol. The analysis of secondary metabolites from the ethanol extract of eggplant peels used tube test and thin-layer chromatography. The level of parasitemia and the number of monocytes were calculated from blood smear of mice (Mus musculus) which were treated with extracts at a dose of 0.075 mg/20 g of body weight; 0.15 mg/20 of body weight; and 0.3 mg/20 g of body weight. 3.744 mg/20 g of body weight Dihydroartemisinin-Piperaquine (DHP) was used as positive control and distilled water was used as the negative control. Ethanol extract of the eggplant peels contains groups of alkaloids, flavonoids, terpenoids, steroids, phenolic, and saponins. 0.075 mg/20 g body weight of ethanol extract of the eggplant peels effectively reduces parasitemia and 0.3 mg/20 g body weight of ethanol extract of the eggplant peels effectively increases the number of monocytes in mice. There is no correlation between an increase in the number of monocytes and a decrease in the level of parasitemia.

Biochemical changes in diabetic rats treated with ethanolic extract of Chysophyllum albidum fruit-skin

BackgroundDiabetes mellitus (DM), also known as diabetes, involves a group of metabolic disorders in which blood sugar levels are high over a prolonged period. The present study was designed to evaluate the effect of 21 days administration of 100 and 200 mg per kg bodyweight of ethanolic extract of Chrysophyllum albidum (African star apple) fruit-skin on streptozotocin (STZ)-diabetic Wistar albino rats. A randomized control trial was used. Diabetic state of test rats was induced with streptozotocin at a dose of 60 mg streptozotocin/kg body using saline (0.9% w/v NaCl) as vehicle. Upon confirmation of diabetic state, crude ethanolic extract of C. albidum was dissolved in citrate buffer at pH 4.2 before administration to the rats at specific doses.ResultsResults show a significant (p < 0.05) decreased in the level of plasma creatinine and insulin but increased level of glucose in diabetic rats relative to control. Induction of diabetes significantly increased the activities of alanine aminotransferases and aspartate aminotransferases in the liver and kidney and activities of both enzymes were also correspondingly increased in the plasma. There was significant increase in the level of total cholesterol, low-density lipoprotein-cholesterol, very low-density lipoprotein-cholesterol and triglyceride, but decreased high-density lipoprotein-cholesterol in the test rats. Results also show alterations in the antioxidant status of experimental rats. The diabetic-induced changes were reversed in diabetic rats upon administration of C. albidum extract at a dose of 200 mg/kg body weight to levels comparable with control.ConclusionThe findings obtained revealed that ethanolic extract of C. albidum fruit-skin at a dose of 200 mg/kg body weight reversed the effect of diabetes due to its antihyperglycemic, anti-hyperlipidemic and antioxidant properties. The antidiabetic effect of the extract may be due to its abundant flavonoid and alkaloid contents.

The effect of ethanolic extract of Annona muricata leaf on the basal ganglia

Annona muricata (Linn.) is an evergreen tropical tree of the Annonaceae family that possesses phytotherapeutic bioactive compounds known as annonaceous acetogenins effective for the treatment of cancers and several diseases. This study investigated the effect of ethanolic extract of Annona muricata leaf on the basal ganglia. Twenty four (24) adult wistar rats were randomly divided into four groups (A, B, C & D) of six animals each. Group A served as the control and received 2 ml/kg of distilled water; the experimental groups B, C & D were orally administered 100 mg/kg, 200 mg/kg and 300 mg/kg body weight of ethanolic extract of Annona muricata leaf respectively for thirty days. At the end of administration, the animals were anaesthetized under the influence of chloroform vapour, dissected and their brain harvested for histological examination. The histological result revealed mild increase in the number of basal ganglia nuclei cell body (BGNCB) and fibres (F) with mild necrosis of neurons when compared to their control group. In conclusion, high consumption of ethanolic extract of Annona muricata could result in extrapyramidal side effects. Thus, it should be taken at lower doses.

Folic Acid Reverses the Effects of Cannabis on the Brain of New Born Wistar Rats

There are conflicting reports on the effect of Cannabis on brain cells, some reports support damage to brain cells while others do not. This work was carried out at the neuroscience unit of the Department of Veterinary Anatomy, University of Ibadan Oyo State, Nigeria. It investigated the neurodegenerative effect of extract of Cannabis sativa plant on brain regions in newborn Wistar rats exposed to Cannabis in utero and also combining the antioxidant and cell proliferative properties of folic acid to reverse these changes particularly in the Purkinje layer of the cerebellum in the group that received folic acid and cannabis. Four groups of pregnant Wistar rats were treated from Day 5 to 20 of pregnancy as follows: group A received 2ml of normal saline solution per os, group B received 2.0 mg /kg body weight of ethanolic extract of Cannabis sativa plant dissolved in normal saline per os, group C received 2.0 mg /kg body weight of Cannabis sativa extract and 40 mg/kg body weight of folic acid tablets (Emzor®) and group D received 2 mg/kg body weight of folic acid per os. The rat pups from group B showed deficit in locomotor function with spongiosis and astrogliosis in the corpus callosum, cerebellum and hippocampal regions of the brain. While pups from group A showed normal locomotor activities with no visible lesions in regions of the brain such as the cerebrum, cerebellum and the hippocampus. Group C pups were presented with normal locomotor activities with congestion of vessels in cerebrum and meninges and scattered areas of cell loss in the cerebrum, cerebellum hippocampus and corpus callosum and group D pups showed normal locomotor function, with vascular congestion in the meninges and cerebrum. We, therefore, concluded that folic acid which is a crucial factor in cell division, neurotransmitter production and an antioxidant in the nervous system could have a reversal of behavioural and locomotor deficits on nervous tissues exposed to Cannabis sativa extract by reducing the rate of cell death and increasing cellular stability and integrity in brain.
