The study was carried out to investigate the anti-diabetic effects of two medicinal plants Cataranthus roseus (C.R) and Nauclea latifolium (N.L) on some biochemical indices of streptozotocin induced diabetic albino wistar rats. Methods: Ethanolic leaf extracts of C.R. and N.L. were given at daily doses of 500 mg/kg body weight in two divided doses each for 14 days. Thirty albino wistar rats were divided into five (5) groups, consisting of 6 rats each viz: Group 1(normal control), Group 2 (diabetic control), Group 3 (insulin treated), Group 4 (received N.L) and Group 5 (received C.R.). Results: The results of the phytochemical screening contain flavonoids, polyphenols, and alkaloids were found to be present in appreciable amount in N.L while saponins and tannins were found in traceable concentration. Fasting blood glucose levels showed significant decrease (P<0.05) in all the test groups compared to diabetic control and closely related to the insulin treated groups. A significant increase (P<0.05) was observed in (TG) and (TC) concentration of all treated groups compared to the diabetic control group. The concentration of HDL was significantly increased while there was also a significant decreased (P<0.05) in VLDL and LDL in the diabetic control group and insulin group when compared to the normal control group, except for C.R treated group that shows a significant decrease compared with the diabetic control group. Enzymes activities were increased in insulin and diabetic groups. A significant reduction (P<0.05) was observed with the treated group of C.R. and N.L compared to the normal control group. Also, observed was a decrease in albumin level in groups treated with the extracts. Marked reduction in total protein level was observed in groups treated with extracts and insulin, compared to the normal control group. Serum concentrations of Na+, K+, Cl- in diabetic control groups showed a significant increase (P<0.05) compared to the normal control group. K+ concentration was observed to be significantly decreased (P<0.05) in all groups treated with extract and insulin compared to the normal control group. Conclusions: The results demonstrated that C. roseus and N. latifolium have anti-diabetic and antihepatotoxic properties and could be potential herbal remedy in treating and managing diabetic conditions.

Purpose: To investigate the antidiabetic effect of methanol extract of Aruncus dioicus, and the underlying mechanism(s). Methods: Twenty-four adult female albino mice were randomly assigned to four groups of six mice each: normal control group, diabetic control group and two treatment groups. With the exception of normal control group, the diabetic control and treatment groups consisted of leptin receptor-deficient (db/db) type 2 diabetic mice. The diabetic control group was not treated, while the treatment groups received 200 or 400 mg/kg extract/day orally for 4 weeks. The effect of the extract on fasting blood glucose (FBG), proprotein convertase subtilisin/kexin type 9 (PCSK9), glycogen and lipid profiles were determined. The expressions of PCSK9, low-density lipoprotein receptor (LDL-R) and glucokinase (GCK) were determined in liver tissues using western blotting and real-time quantitative polymerase chain reaction (qRT-PCR). Results: Fasting blood glucose (FBG) was significantly and dose-dependently reduced in the treatment groups, relative to diabetic control group at different time-points (p < 0.05). Total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were significantly higher in the diabetic control group than in normal control group (p < 0.05). However, treatment with methanol extract of A. dioicus significantly and dose-dependently reversed the changes in the levels of these parameters (p < 0.05). The expressions of LDLR and GCK were significantly down-regulated in diabetic control group, when compared with normal control group, but their expressions were significantly dose-dependently upregulated in the treatment groups (p < 0.05). Treatment with the extract significantly and dose-dependently down-regulated PCSK9 expression (p < 0.05). Liver injury characterized by large distended lipid droplets and fat accumulation was seen in diabetic mice, but treatment with methanol extract of A. dioicus significantly reversed the histopathological changes induced by DM. Conclusion: These results indicate that the antidiabetic effect of methanol extract of A. dioicus is exerted via a mechanism involving PCSK9/LDLR pathway.

The influenceof antioxidant supplementation on high fat diet-streptozotocin (HFD-STZ) induced type 2 diabetes mellitus in Wistar albino rats was investigated. Appropriate (RDA) proportions of some antioxidant rich substances which includes; vitamins (A, B3, B6, B12, C and E), minerals (calcium, selenium, chromium, magnesium, potassium and zinc), α-lipoic acid, cinnamon powder, curcumin (Meriva®), cordyceps, resveratrol, quercetin, D-ribose-L-cysteine were pulled together in corn oil and stored at 4°C for use. Serum glutathione (GSH) and malondialdehyde (MDA) levels, as well as activities of antioxidant enzymes: superoxide dismutases (SOD), catalase (CAT), glutathione-s-transferase (GST), glutathione peroxidise (GPx) and glutathione reductase (GR) were measured using standard methods. Data analysis was done with SPSS version 20.0 and significant level was set at P≤0.05. Results of in vitro oxidative stress indices and antioxidant enzyme activity indicate that after 4 weeks of treatment, there was no significant change (p≥0.05) in serum FBS levels of treated groups compared to the normal control group, but there was a significant decrease (p≤0.05) after 8 and 12 weeks of treatment when compared to the diabetic control group. There was no significant difference (p≥0.05) in the activities of antioxidant enzymes when compared to the normal control group, while in the diabetic control there was significant increase (p≤0.05) compared to the other groups. The results after 4, 8 and 12 weeks of treatment showed a significant increase (p≤0.05) in serum GSH level of normal and treated groups compared to diabetic control group, whereas there was a significant decline (p≤0.05) in serum MDA level of treated and normal control groups when compared to diabetic control. The results therefore suggest that the supplement may possess significant (p≤0.05) free radical scavenging potentials which could be beneficial to health.

Purpose: To evaluate the effects of an okra-based diet on streptozotocin-induced diabetes mellitus in adult Wistar rats and its mechanism of action.Methods: Wistar rats (6) were administered streptozotocin (50 mg/kg ip) after an overnight fast. Upon confirmation of diabetes mellitus, the animals were fed ad libitum for 21 days with formulated okrabased test diet in place of normal diet. The rats treated similarly with streptozotocin and fed ad libitum with the normal diet served as diabetic control while rats fed on normal diet and not treated with streptozotocin served as the negative control. Thereafter, the rats were sacrificed, fasting bloodcollected and analysed for glucose concentration and biochemical parameters. Pancreas was also excised for histopathological studies.Results: There was a significant increase in body weight, HDL-cholesterol (p< 0.05) but significant decrease in blood glucose (p < 0.05), serum total cholesterol, triglyceride, LDL-cholesterol and VLDLcholesterol concentrations in the okra-fed diabetic treated rats when compared to the diabetic control group. Furthermore, superoxide dismutase activity (SOD) was significantly higher in the diabetic control, and reduced significantly when fed with okra-based diet (p < 0.05). Catalase (CAT) activity was significantly (p < 0.05) decreased in diabetic control and treated group, whereas it was significantly (p < 0.05) increased in normal control rats. There was a significant (p < 0.05) decrease in reduced glutathione levels. The significant (p< 0.05) increase in malondialdehyde in the diabetic group was significantly decrease in the diabetic rats fed with okra-diet. Also serum insulin level was significantly (p < 0.05) increased and serum α amylase activity was significantly (p < 0.05) decrease in the diabetic treated rats. Histology results show that there was damage to the β cells of the pancreas in the diabetic control when compared to normal control, but rats fed okra diet was able to regenerate endocrine β cells.Conclusion: Okra-based diet lowers hyperglycaemia as well as regenerate/repair endocrine β-cells and exocrine tissues of the pancreas damage by streptozotocin Keywords: Abelmoschus esculentus, Diabetes mellitus, anti-diabetic, Insulin, α-amylase, Mechanism

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.

Effect of fenugreek (Trigonella foenumgraecum) on thymic volume was studied in 30 long Evansrats. Among the total, 10 were treated with only vehicle (non-diabetic control - group A); 10 weretreated with streptozotocin only (diabetic control - group B) and 10 were treated with fenugreek(fenugreek treated - group C). Mean relative thymic volumes were 0.22210.018 ml/100 gm ofcorresponding final body weight (Mean 1 SEM), 0.14710.015 and 0.19910.020 in group A, B and Crespectively. In non-diabetic control group the thymic volume was significantly higher (p=0.005)than that of diabetic control group. In fenugreek treated diabetic group the volume was alsosignificantly higher (p=0.05) from that of diabetic control group and very much nearer to nondiabeticcontrol group (p=0.398). Fenugreek may preserve the thymic volume considerably indiabetic rats.doi: 10.3329/taj.v16i1.3892TAJ June 2003; Vol.16(1): 1-4

Atractylodes Macrocephala

Atractylodes macrocephala polysaccharide (AMP), a traditional Chinese medicine, is thought to have protective effects against liver injury. Therefore, this study was designed to explore the effects of AMP on hepatic ischemia–reperfusion injury (IRI) and elucidate the possible mechanisms. Ninety-six Sprague-Dawley rats were randomly divided into four groups with 24 rats per group: a normal control group, an IRI group, an AMP-treated group (0.4 g/kg/d) and a bifendate-treated group (100 mg/kg). Rats were treated with AMP or bifendate once daily for seven days by gastric gavage. The normal control group and the IRI model group received an equivalent volume of physiological saline. At 1, 6 and 24 h after surgery, the rats were killed and liver tissue samples were obtained to determine interleukin-1 (IL-1) expression by Western blotting and nuclear factor-κB (NF-κB) expression by immunohistochemistry. Liver morphology was assessed by microscopy and transmission electron microscopy. Blood samples were obtained to measure liver function (alanine aminotransferase, aspartate aminotransferase, total bilirubin and direct bilirubin). AMP significantly reduced the elevated expression of markers of liver dysfunction and the hepatic morphologic changes induced by hepatic IRI in rats. AMP also markedly inhibited IRI-induced lipid peroxidation and altered the activities of the antioxidant enzyme superoxide dismutase and malondialdehyde levels. Moreover, pretreatment with AMP suppressed the expression of interleukin-1β and NF-kB in IRI-treated rats. These results suggest that AMP exerts protective and therapeutic effects against hepatic IRI in rats, which might be associated with its antioxidant properties and inhibition of NF-κB activation. More studies are needed to better understand the mechanisms underlying the protective effects of AMP on hepatic IRI.

Local Nigerian men have been using AuriculariaPolytricha as a treatment for sexual dysfunction without supporting evidence from scientific experiments. This study was to investigate the effect of ethanolic extract of A. Polytricha on testicular DNA expression and some oxidative stress markers using STZ-Induced diabetic rats as a model. The experiment included six groups, Group A (Normal Control, treated with normal saline), Group B (treated with 65mg/kg.bw of STZ), Groups C, D, and E (treated with 250mg/kg.bw, 500mg/kg.bw, 1000mg/kg.bw AP after inducing diabetics), and Group F (treated with 40mg/kg.bw metformin after inducing diabetics). The experiment lasted for 35 days. After termination of the experiment, Fuelgen nuclear reaction was used for DNA demonstration to assess testicular DNA distribution while serum Superoxide Dimutase (SOD), Catalase and Melondialdehyde where evaluated using reagent based antioxidant enzyme assay. Results reveals that SOD and Melondialdehyde activities were remarkably (p<0.05) higher in diabetic control animals when compared with the normal control group. Values in Groups C, D and F that were administered with 250, 500mg/kg.bw A. polytricha and metformin respectively were also significantly (p<0.05) increased when compared with the normal control group. However, diabetic animals placed on 1000mg/kg.bw A. polytrichadid not show any statistical significance in comparison with normal control group but was remarkably (p<0.01) decreased when compared to the diabetic group that received low dose A. polytricha, an indication that the reversal is dose dependent. Catalase concentration in diabetic control animals was remarkably (p<0.05) higher when compared to the normal control but was not significantly (p<0.05) different in groups D (DM+500mg/kg.bw A. polytricha) and E (DM+1000mg/kg.bw A. polytricha) when compared with the normal control group. Diabetic control animals showed reduced magenta colour intensity of DNA and increased clustering and cross linking of DNA strands when compared with the normal control. However the degree of cross link in DNA strands was reduced in the diabetic animals placed on 1000mg/kg.bw A. polytrichawhen compared with the diabetic control group. Reversal in DNA damage and values of serum oxidative stress markers following administration of graded doses of A. polytricha could be attributed to essential phytochemical and therapeutic constituents in A. polytricha like polyphenol and flavonoid which can be found useful in prevention and treatment of diabetes induced testicular dysfunction. In summary, AP can contribute to a reversal in DNA damage and levels of serum oxidative stress markers in treating diabetes-induced testicular dysfunction.

Aims: The effect of pre and post-infection administration of zinc and selenium on Trypanosoma brucei brucei infection in wistar rats on some biochemical parameters were investigated. Study Design:  The study was designed to evaluate the effect of pre and post infection administration of zinc and selenium on Trypanosoma brucei brucei infection in wistar rats. Place and Duration of Study: The study was conducted at the Nigerian Institute for Trypanosomiasis Research (NITR), Kaduna and Department of Biochemistry, Ahmadu Bello University (ABU), Zaria, between January 2014 to March 2014. Methodology: Fifty four (54) wistar rats were divided into nine groups of six (6) rats each. Groups III-IX were infected intraperitoneally with 1x103parasite load. Animals in group III were                       infected but untreated while the infected/treated groups received prophylactic (IV, V and VI) and therapeutic (VII, VIII and IX) treatment with zinc and selenium 50mg/kg and 10mg/kg body weight respectively. Results: Results obtained showed that serum alkaline phosphatase (ALP), alanine amino transferase (ALT) and aspartate amino transferase (AST) activities in the infected-untreated control group were significantly different (P<0.05) and higher as compared to infected treated and normal control. Similarly, the two minerals significantly decreased (P<0.05) the levels of Urea and Creatinine in the infected treated when compared to the infected untreated rats, with the exception of creatinine value of the post-infected treated with selenium where there was no significant (P>0.05) decrease. On the other hand, a significant (P<0.05) increase in serum levels of total Protein, albumin and total bilirubin and no significant (P>0.05) difference in direct bilirubin was recorded in infected treated group compared to infected untreated and normal control. Conclusion: It was concluded that administration of zinc and selenium ameliorate the infection-induced biochemical changes in tissues and organs associated with Trypanosoma brucei brucei infection in Wistar rats.

The study performed some experiments and made following conclusions. In the prevention stage, comparing with normal control group, triglycerides, blood sugar (BG), 24-hour urinary protein and cholesterol (CHO) were higher in T2DM group, but weight and urea nitrogen (BUN) was less in that group. 24-hour urinary protein and cholesterol (CHO) were higher in T2DM group than the intervention group. 24-hour urinary protein and BG in the intervention group were also observed to be higher than the normal control group, but BUN was less than the normal control group. In the intervention group, the weight of kidney and the weight of rat were also higher than T2DM group, but CHO and 24-hour urinary protein were less than T2DM group. The expression of TGF-β1 in T2DM group was also observed to be more than the other groups. However, in the treatment stage, serum creatinine (Cr), weight, BG and CHO, TGand 24-hour urinary protein were significantly higher in the DN rats than those in the normal control rats (P>0.05). The expression level of TGF-β1 and triglyceride level in the corn silk dihydroxycorn silk3 treated group were noticeably lower than those in the DN rats.

The methanolic leaf extract of Vernonia amygdalina (MLVA) was assessed to evaluate its antidiabetic potential in rats. Diabetes was induced in male Wistar rats by the administration of alloxan monohydrate at 100 mg/kg of body weight. After 48 h, rats with fasting blood glucose levels of 200 mg/dL and above were considered diabetic and used for the study. The experimental animals were grouped into five groups (A–E) of 10 animals each. Group A rats were non-diabetic normal control, Group B consisted of diabetic control rats that received no treatment, groups C, D and E rats were diabetic rats but treated with glibenclamide, 200 and 400 mg/kg doses of MLVA respectively. Blood samples were collected at days 14 and 28 after induction for haematological and serum biochemical indices such as triglycerides, LDL, cholesterols etc. The intestine was collected and intestinal homogenate was prepared for the antioxidant studies. The extract at 200 mg/kg and 400 mg/kg doses significantly (p < 0.05) reduced blood glucose levels in extract-treated diabetic rats and also significantly increased weight gain in these rats. Most haematological parameters in treated rats experienced, while platelets and neutrophils were decreased. Biochemical indices measured were reduced in MLVA-treated groups compared with diabetic control. Treatment with MLVA also produced significant (p < 0.05) decrease in markers of oxidative stress but increased levels of enzymic and non-enzymic antioxidant markers in intestinal homogenates of treated groups compared with diabetic control. This study showed that V. amygdalina has antihyperglycaemic and in vivo antioxidant effects.
