Ethnomedicinal survey have shown that the different parts of Hunteria umbellata plant are used in Western and Southern parts of Nigeria in managing various human diseases such as sexually transmitted infections and to induce or augment labor. This is however, without information on its effect on reproductive functions. This study was therefore designed to ascertain if there is any health benefit or risk in the ingestion of Hunteria umbellata on reproductive functions. In this study, qualitative phytochemistry, acute toxicity test and the sub-chronic toxicity effects of 250, 500, and 1000 mg/kg/day of Hunteria umbellata (HU) methanol seed extract on reproductive functions in male and female Wistar rats were investigated for 90 days. To achieve this, effect of repeated doses of methanolic extracts of Hunteria umbellata seed were investigated on selected reproductive parameters of the test animals. Eighty (80) (40 male and 40 female) Wister rats, were randomly divided into 4 groups of 10 rats each. The first group received 10 ml/kg/day of distilled water and served as the control, while the second, third and fourth groups received 250, 500 and 1000 mg/kg/day of the extract for 90 days respectively. Blood samples were collected by retro-orbital puncture and delivered into plain tubes for hormonal assay, using ELISA hormone test kits (Biotec Laboratories Ltd, UK). After 90 days, the rats were anesthetized using chloroform. The histology of the testes and ovaries were also carried out. Result revealed that the prolonged treatment with methanol seed extracts of Hunteria umbellata for 90 days, caused minimal decreases (p>0.05) in testosterone, estrogen, progesterone level in all the extract treated groups as compared with the control group. Also, no significant distortions were observed in the histology of testes and ovaries. The results suggests that the prolonged oral treatment with 250-1000 mg/kg/day of the methanol extract of the seed of Hunteria umbellata did not have any effect on the reproductive functions as well as the reproductive organs in males and females’ rats treated, and could be safe following repeated use.

Introduction and Aim: Oxidative stress plays a very important role in endosulfan-induced toxic effects on reproductive organs. Vitamin C is a potent antioxidant which plays an important role in decreasing oxidative stress. The present study was aimed to investigate the protective role of vitamin C against endosulfan-induced testicular toxicity in Wistar rats. To investigate a protective effect of vitamin C against endosulfan induced toxicity on biochemical changes. Materials and Methods: Seventy male neonatal Wistar rats were divided into  seven groups. The group  I was taken as the control group, the endosulfan-treated were grouped into II (3 mg/kg body weight (BW) and group III (6 mg/kg BW), Group IV (9 mg/kg BW) and Group V (12 mg/kg BW). Group VI (9 mg/kg BW) and group VII (12 mg/kg BW) were pretreated with vitamin C (20 mg/kg BW) for 60 days. After  the experimental procedures, the testicular weight, lactate dehydrogenase (LDH) enzyme and testosterone in plasma, LDH, steroidogenic enzymes 3?-HSD and 17?-HSD in testis were evaluated. One-way ANOVA was used to determine the statistical significance. Results: Significant improvement in the testicular weight (P<0.05) , LDH (P<0.05) levels both in plasma and testis, increase in testosterone(P<0.001) and steroidogenic enzyme levels(P<0.001) was observed in the group pretreated with vitamin C treated group when compared to the endosulfan treated group. Conclusion: Vitamin C decreases the toxic effect of endosulfan on testis. The present action might be  due to its antioxidative properties.

Background. In this study, the male fertility-enhancing activity of 100, 200, and 400 mg/kg/day of Hunteria umbellata water seed extract (HU) in Wistar rats was studied for 60 days. In doing this, effect of repeated doses of HU was studied on the weight gain pattern, gonadosomatic index (GSI), serum follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone (TS), prolactin (PRL), and estradiol (ES)} as well as testicular antioxidant status of the treated rats as a way of elucidating the mechanism(s) of action of HU. Method. Thirty-six (36) male Wistar rats were randomly divided into six groups (I-VI) of six rats per group. Group I rats were gavaged with 10 ml/kg/day of distilled water and served as an untreated control; Group II rats were gavaged with 0.3 mg/kg/day of clomiphene in distilled water; Groups III-V rats received 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day of HU, respectively, and Group VI rats received 20 mg/kg/day of Vitamin C all in distilled water. All treatments were for 60 days after which the treated rats were humanely sacrificed. Sera of blood samples were processed for the above stated hormonal profile. Similarly, testicular tissues obtained were processed for semen analysis and complete antioxidant profile of the HU-treated testicles by assaying for superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH), glutathione reductase (GSR), glutathione peroxidase (GSH-Px), and Thiobarbituric Reactive Species (TBARS). Results. Prolonged treatments with 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day of HU for 60 days induced dose dependent reductions in weight gain pattern with the most significant (p<0.001) effect recorded with the highest dose of HU. Conversely, significant (p<0.001) increase was recorded for GSI at the same HU dose. Clomiphene and HU also induced significant (p<0.01, p<0.001) dose dependent increases in the total sperm count, %live sperm, but reverse effects on %dead sperm and %abnormal sperm. On the hormonal profile, oral treatment with 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day of the extract induced profound (p<0.05, p<0.01, and p<0.001) dose related increases in the sera TS, LH, and FSH while it caused reverse effect on serum PRL but caused no significant alterations in the serum ES levels. Similarly, oral treatment with vitamin C and 100-400 mg/kg/day of HU induced profound (p<0.05, p<0.01, and p<0.001) increases in the antioxidant enzyme activities. Conclusion. Overall, prolonged oral treatment with 100-400 mg/kg body weight of HU for 60 days significantly improved sperm function which was mediated via enhanced spermatogenesis, steroidogenesis, and antioxidant mechanisms.

The acute and subacute toxicity profile of the aerial extract ofMonsonia angustifoliain Wistar rats was evaluated. The Organization for Economic Cooperation and Development (OECD) 420 guideline was adopted in the acute toxicity testing with a single oral dose of 5000 mg/kg (b.w.). For the 28-day daily oral dosing, the extract was administered at 75, 150, and 300 mg/kg b.w.; 1% ethanol in sterile distilled water was used as control. Clinical toxicity signs were subsequently evaluated. At a single dose of 5000 mg/kg b.w. the extract elicited no treatment-related signs of toxicity in the animals during the 14 days of experimental period. In the subacute toxicity, there was no significant difference in hematological, renal, and liver function indices. However, dose-dependent significant increases were observed on the plasma concentrations of white blood cell and platelet counts of the treated animals compared to the control group. While cage observations revealed no treatment-facilitated signs of toxicity, histopathological examinations of the kidneys and liver also showed no obvious lesions and morphological changes. These results suggest that the extract may be labelled and classified as safe and practically nontoxic within the doses and period of investigation in this study.

Abstract Objective The aim of this study was to analyze the effect of grape seed extract containing cyanidin on osteoclastogenesis (by means of receptor activator of nuclear factor-κ B ligand [RANKL] and osteoprotegerin [OPG] levels) and the number of osteoclasts during orthodontic relapse in Wistar rats. Materials and Methods This study is an in vivo quasi experimental research. A total of 32 male Wistar rats were used in the study, which were randomly split equally into two groups, grape seed (GS) and control group (CG). All rats were given an orthodontic force of 35 cN using a stainless steel 3-spin coil spring that was activated for 7 days and then conditioned to be passive. During this phase, the GS group was administered grape seed extract containing cyanidin once per day. Orthodontic appliances were removed from both groups afterward, and then the alveolar bone tissue was isolated consecutively according to observation days (days 1, 3, 7, and 14), while OPG and RANKL levels were analyzed in their gingival crevicular fluid using a specific enzyme-linked immunosorbent assay (ELISA). Tissues were then stained with hematoxylin–eosin (H&E) and observed under a light microscope to count the number of osteoclast cells. Data were analyzed statistically using an independent t-test (p < 0.05). Results The number of osteoclasts in the GS group was significantly lower than that in the CG group on all experiment days (p = 0.021; p = 0.001; p = 0.024; p = 0.001; p < 0.05). ELISA results showed that the RANKL level of the GS group was significantly lower on days 3 and 7 (p = 0.025; p = 0.039; p < 0.05), while the OPG level was significantly higher on days 1 and 3 in the GS group than in the CG group (p = 0.039; p = 0.021; p < 0.05). Conclusion Grape seed extract can prevent postorthodontic relapse movement by inhibiting osteoclastogenesis and reducing the number of osteoclasts in Wistar rats.

ABSTRACT     Background and Objectives: Probiotics are live microorganisms that, when administered in an adequate amount, confer a health benefit on the host through the gut. Saccharomyces cerevisiae is a widespread yeast found in nature. This microor- ganism has been used as a probiotic agent in recent years. In this study, the effect of microencapsulation on survival rate of S. cerevisiae var. boulardii in the simulated gastrointestinal tract medium and the impact of microencapsulated S. cerevisiae var. boulardii on some serum biochemical factors in a rat model was evaluated. Materials and Methods: 30 male wistar rats were divided into three groups (control, rats receiving microencapsulated S. cerevisiae var. boulardii, and rats receiving S. cerevisiae var. boulardii alone). The probiotic was gavaged at a dosage of 2 gr/ kg BW for 8 weeks. Blood was collected from rats at the end of the treatment period and biochemical factors were measured using Mancompany kits. Results: The results showed a significant increase in viability of microencapsulated S. cerevisiae var. boulardii in compar- ison with free S. cerevisiae var. boulardii (p<0.05). Weight of rats in probiotic treated groups was significantly higher in comparison with the control group (p<0.05). Moreover, probiotic treatment reduced mean levels of triglycerides, cholesterol, free blood sugar and liver enzymes in rats. Conclusion: Microencapsulation could increase the survival rate of yeast probiotics in the gastrointestinal tract; however, more studies are needed for better understanding of the exact effect of microencapsulation on probiotics’ function.

The prevalence of parasitic infections such as malaria, which leads to decrease in hematological indices, the major cause of anemia, constitutes a serious health challenge in many developing countries such as Nigeria. This study investigated the effect of methanol seed extract of Aframomum melegueta on selected hematological indices of 2,4-dinitrophenylhydrazine (2,4-DNPH)-induced anemic rats model. The toxicity study and qualitative phytochemical screening of the extract were carried out using standard procedure. Twenty Wistar rats were grouped into five of four rats each (n = 4). Group I: Normal control; Group II: Negative control; Group III: administered 20 ml/kg b.w. of Astifer (Standard drug); Group IV and V were administered 200 and 400 mg/kg b.w. of the extract, respectively. The animals of Groups II to V were induced with 2,4-dinitrophenylhydrazine (20 mg/kg b.w.) once daily for seven consecutive days; their blood samples were collected by ocular puncture into heparinized capillary tubes for hematological analysis and animals with packed cell volume (PCV) ≥ 30% reduction were considered anemic for the study. The result of the qualitative phytochemical analysis showed that the methanol extract tested positive to alkaloids, carbohydrate, saponins, flavonoids, steroids, terpenoids, and anthraquinones. Acute toxicity and lethality studies on methanol extract showed an oral LD50 equal or less than 5000 mg/kg b.w. in mice. The rats administered 20 ml/kg b.w. of Astifer showed significant (P < 0.05) increase in PCV, hemoglobin, red blood cell (RBC) count, white blood cell (WBC) count, and neutrophils count compared with the normal control animals. The rats administered 200 mg/kg b.w. of A. melegueta showed significantly (P < 0.05) higher PCV and WBC count; non significant (P > 0.05) decrease in hemoglobin count, RBC, platelet, neutrophils and lymphocyte count compared with the normal control animals. The rats administered 400 mg/kg b.w. of A. melegueta showed significant (P < 0.05) increase in hemoglobin, platelet, erythrocyte sedimentation rate (ESR) and neutrophils count; non significant (P > 0.05) lower PCV, RBC, WBC count, and lymphocyte count compared with anemic rats administered with 0.3 ml of normal saline. It can be concluded that Aframomum melegueta seed has beneficial immunological and hematological properties in Wistar rats and possessed erythropoietic potentials at minimal dose that support its use for treating anemia.

The experiment was conducted on 90 adult healthy Wistar rats. Rats were randomly divided in to 15 equal groups, each of 6 rats, and were kept in separate cages. Group I served as normal healthy control without any treatment, while Group II and III served as vehicle (bicarbonate) control and lithiatic control, respectively. In rats of Group III to IX urolithiasis was induced using 0.75 % (v/v) ethylene glycol and 2% (w/v) ammonium chloride in drinking water for 28 days. The rats of Group I, II, and X to XV were given pure wholesome water till 28 days. After 28th day, the rats of urolithiatic treatment Groups IV, V, VI, VII, VIII and IX were given aqueous and alcoholic extracts of Bryophyllum calycium and Solanum xanthocarpum @ 300 mg/kg bwt orally as either single extract or combination as biherbal extracts in 0.5 % sodium bicarbonate using syringe and rat lavage needle, and so also was done for rats of Group X to XV as extract control groups. Blood samples were collected twice: i.e. on day 28 of induction of urolithiasis and then on day 56 of experiment from all rats. No significant difference was observed in any of the haematological parameters and even in serum albumin and globulin levels before and after treatment in different groups. However, increased levels of serum BUN, uric acid and creatinine were observed in the urolithiatic groups as compared to the normal control group on 28th day. While serum total protein levels were decreased in the calculi induced groups as compared to the normal control group. However, co-treatment of aqueous or alcoholic extract of Bryophyllum calycinum and Solanum xanthocarpum significantly restored these changes by 56th day. The effect of biherbal alcoholic extract of the plants was much better in restoring the values and the levels came nearer to normal by 56th day of oral treatment proving nephroprotective effect of these extracts.

This study investigated the hepatoprotective effect of methanol seed extract of Citrus tangerina on liver damage induced by paracetamol in laboratory rats. Wistar rats were used in this study and categorized into five groups. Groups 1 and 2 received 10 ml/kg normal saline orally, groups 3 and 4 were administered 200 mg/kg and 400 mg/kg respectively of Citrus tangerina seed extract orally, while silymarin 100 mg/kg served as standard drug treatment for group 5. Following six (6) days of pretreatment with the extract, hepatotoxicity was induced with paracetamol 3 g/kg (orally) in all the groups except the positive control group. At the end of the experiment (24 hours after induction), blood samples were collected under diethyl ether anaesthesia for biochemical markers of liver enzymes and antioxidative stress and the liver was harvested for histopathological studies. Both doses (200 mg/kg and 400 mg/kg) of Citrus tangerina seed extract significantly (p < 0.05) reduced the liver enzymes level, but significantly (p < 0.05) increased antioxidant enzymes when compared with the negative control group. Liver histology showed that the Citrus tangerina seed extract prevented hepatic injury induced by paracetamol. The methanol seed extract of Citrus tangerina possesses antioxidative and hepatoprotective effects.

Dacryodes edulis (African pear) seed has a long history of use in ethnomedicine. However, there is a paucity of information on its ameliorative potential on hepatic damage. In the present study, the potentials of D. edulis ethanolic seed extract (DET) in attenuating carbon tetrachloride (CCl4)-induced hepatotoxicity in male Wistar rats was assessed. Ninety male Wistar rats were divided into 3 groups (n = 10) designated: control, CCl4, and DET, respectively. Animals in the control group were administered 2 mL/kg body weight corn oil, while those assigned to CCl4 and DET groups were administered i.p. 30% CCl4 in corn oil (1:1 v/v) at 2 mL/kg. Treatment was administered once every 24 h consecutively for 72 h. Thereafter, control and CCl4 groups were treated once daily with 1 mL distilled water by gavage, while DET rats were treated once daily with 1500 mg/kg DET by gavage. At every 7 days interval and for 28 consecutive days, animals were starved overnight, weighed, and six rats from each group were sacrificed under anesthesia to collect blood and liver samples. After 28 days, remarkable improvements in feed intake, body weight, serum levels of hepatic function indicators, and hepatic histology were observed in DET rats compared to CCl4 rats. These results suggest a possible ameliorative potential of D. edulis ethanolic seed extract against CCl4-induced hepatic injury.
