This study was carried out to evaluate the possible mechanisms through which an aqueous extract from MO leaves demonstrates hepatoprotective effects in alloxan-induced diabetic rats. Eighty albino rats were assigned to 4 groups. The control group was orally administered sterile saline. The second group was injected with alloxan (150 mg/kg body mass (b.m.)) by intraperitoneal injection (i.p.). The third group was given MO (250 mg/kg b.m.) orally, daily. The fourth group was injected with alloxan, as for the second group, and administrated an aqueous extract of MO leaves, as for the third group. Alloxan induced degenerative changes in hepatic and pancreatic tissues, increased hepatic lipid peroxidation, and increased gene expression of PC and caspase 3. However, it decreased the activities of hepatic SOD and CAT, and gene expression of GS. In contrast, the MO extract prevented changes to the histoarchitecture of hepatic and pancreatic tissues and normalized the reduced hepatic levels of glutathione, as well as the activities of SOD and CAT, and the gene expression of GS, while reducing blood glucose levels, hepatic lipid peroxidation, and the gene expression of PC and caspase 3. This study indicated that an aqueous extract of MO leaves can be a potent antioxidant and used as an hepatoprotective agent.

To investigate the antihyperglycemic and antihyperlipidemic effect of Momordica charantia (Karala), the aqueous extract of the Karala fruit was tested on streptozotocin (STZ)-induced diabetic rats. Thirty six albino rats were used in the experiment, 30 diabetic and the remaining six as negative control (T1). Diabetes was induced by administering (injecting) STZ at dose of 55mg/kg body weight. Thirty diabetic animals were randomly divided into five groups such as diabetic control group (T2) without any application of treatment, and groups T3,T4,T5 and T6 were treated with aqueous extract of Karala fruits daily at the doses of 250,    500 and 750mg/kg and glibenclamide (at a dose of 5mg/kg body weight) respectively. The body weight was taken and blood samples were collected from individual animal to determine glucose levels at 15 day interval up to 90 days. In addition, Asparate  Transaminenase(AST), Alanine Transaminenase(ALT), Alkaline Phosphatase(ALP), Total cholesterol (TCh) and Triglyceride (TGA) were determined at day 15 and at the end of the experiment. All three doses of Karala extracts reduced diabetic induced blood sugar and the reduction is comparable with standard glibenclamide (GLM) dose particularly with higher doses Karala extracts (500 and 750mg). Karala also prevented body weight loss due to induced diabetes as did by GLM treatment.. The treatment also resulted in a significant reduction of Asparate Transaminenase(AST), Alanine Transaminenase(ALT), Alkaline Phosphatase(ALP), Total cholesterol (TCh) and Triglyceride (TGA) activities of treated rats when compared to the STZ induced  diabetic rats. Higher doses of Karala (500 and 750mg/kg) are as effective as standard GLM dose on measured variables. This study demonstrated that Karala has hyperglycemia and antihyperlipidemic effect against STZ induced diabetic rats. These findings open the possibility of using Karala extract to treat diabetic animal and human patients although further research is warranted. DOI: http://dx.doi.org/10.3329/jesnr.v5i1.11550 J.

Evaluation of the phenolic compounds and antioxidant activity ofCedrela odorataL. andJuglans regiaL. bark extracts was performedin vitro.Juglans regiashowed greater extract concentration and higher antioxidant activity. Hypoglycemic activity in rats was assessed by generating a glucose tolerance curve and determining the area under the curve (AUC). Diabetes was later induced by an injection with streptozotocin (65 mg/kg of b.w.) and confirmed after 24 hours. The extract was administered (200 mg/kg b.w.) over 10 days, and blood glucose was monitored and compared with a control group. The glucose AUC showed a hypoglycemic effect ofJ. regiaandC. odoratain normal rats. Both extracts reduced hepatic lipid peroxidation in diabetic rats. Polyphenolic extracts reduced cholesterol levels in a hypercholesterolemic mouse model and decreased hepatic lipid peroxidation. Polyphenolic extract doses of 100 and 200 mg/kg b.w. were administered alone or with cyclophosphamide (CPA) 50 mg/kg ip, which was used as a positive control. Analyses were performed using leukocytes in a comet assay after 4 and 24 h of treatment. Genotoxic effects were evaluated by the comet assay, which showed that whileJ. regiaextract had no effect,C. odorataextract induced slight damage at 200 mg/kg, with the formation of type 0 and 1 comets.

Annona muricata, an herbal plant commonly used in traditional medicine to manage numerous diseases, diabetes as other diseases could be managed with herbal medicine. This study was designed to be investigated the antidiabetic, hypolipidemic, renal protective, and antioxidant effects of aqueous extracts of Annona muricata as used alone or combined with metformin in streptozotocin (STZ)-induced diabetic rats. Methods: the study was involved twenty adult Wister albino rats in four groups (five rats in each) and designated as groups, control group (1), and experimental groups (2, 3, 4). Diabetes was induced in experimental groups by 60 mg/kg intravenous streptozotocin injection. Group 2: serves as a diabetic control group, Group 3: diabetic rats treated with oral administration of 100 mg/kg of Annona muricata aqueous extract, Group 4: diabetic rats treated with combination (100 mg/kg aqueous extract of Annona muricata + 50 mg/kg metformin). The treatment continuous daily for 4 weeks to determine the levels of blood glucose and biochemical analysis. Result: aqueous extract of Annona muricata was reduced the serum glucose level effectively in streptozotocin-induced diabetic rats, by 48% and 55% after 28 consecutive days of treatment when used alone and with metformin, respectively. These compared to the preliminary values and the reduction was statistically significant compared to a diabetic control group. Daily oral administration of 100 mg/kg aqueous extract of Annona muricata for 4 weeks to streptozotocin-induced diabetic rats significantly reduced the level of total cholesterol, urea, creatinine, and MDA, whereas the reduction was non-significant in triglyceride and VLDL-cholesterol levels as compared to the non-treated diabetic group. However, the reduction is more significant in streptozotocin-induced diabetes rats that were treated with a combination of Annona muricata and metformin when compared to the diabetic control group. Conclusion: Aqueous extracts of Annona muricata have anti-diabetic action through their hypoglycemic, hypolipidemic, renal protective, and antioxidant effects in streptozotocin-induced diabetic rats. Thus, can be used alone or with anti-hyperglycemic drugs as metformin in the management of DM. The combination is preferred in severe hyperglycemic cases with more hypoglycemic effect requirements.

AIM: To find a new concept to show whether or not apoptosis of retinal ganglion cells (RGCs) can be determined in the histology of acute hyperglycemia in the role of expressed Brn3b gene related to nitric oxide (NO), caspase-3, nuclear factor kappa-B (NF-κB), and tumor necrosis factor-α (TNF-α) as an early predictor of primary open angle glaucoma (POAG) eyes and their associations. METHODS: Experimental in vivo study was carried out using adult male, white Sprague-Dawley rats aged ≥2mo, weighing 150-200 g. The animals were divided into two groups, one group receiving intraperitoneal injection of streptozotociz 50 mg/kg in 0.01 mol/L citric buffer and pH 4.5 and a comparison made with the control group. Retinal tissue was divided into two parts (both experimental and control groups respectively): a) right retina for immunohistochemistry (IHC; caspase-3 and TNF-α); b) left retina was divided into two parts for the purpose of real-time polymerase chain reaction (PCR) test (RNA extraction for Brn3b gene expression analysis) and ELISA test (NO and NF-κB). RESULTS: The experimental group showed a decrease in Brn3b gene expression compared to the control group (1.3-fold lower in 2nd month; 1.1-fold lower in 4th month and 2.5-fold lower in 6th month). However, there was a decrease of NO, caspase-3, and an increase of NF-κB and TNF-α quantity. CONCLUSION: The expression of mRNA Brn3b gene is inversely proportional to apoptosis in RGCs. The quantity of NO, caspase-3, NF-κB and TNF-α is influential in expression of Brn3b in RGCs caused by hyperglycemia in diabetic rats.

The effects of crude aqueous extract of Ehretia anacua on alloxan induced diabetic rats was investigated. Male albino rats of weighing between 120 to 150 were used, divided into 6 groups of five animals per group. Group I received distilled water throughout of the experiment and served as the control. Group II received 110 mg/kg of alloxan interperitoneally. Groups III, IV, V and VI received 110 mg/kg of alloxan and in addition administered with aqueous Ehretia anacua extract daily for 14 days. Blood glucose level was monitored at five days interval for fourteen days. Target organs (pancrease) was taken from each rat. The histopathological studies of the pancrease were examined. In alloxan - induced diabetic rats, blood glucose level was significantly increased compared with the control rats. Treating diabetic rats with 50, 100 and 200 mg/kg bw Ehretia anacua caused a significant decrease in the blood glucose level. The Photomicrograph of the histopathology examination of the pancrease (× 100) of the groups treated with alloxan showed poor architecture was destroyed whereas those treated with Ehretia nancua showed normal architecture. This illustrates the amelliorative effects of the extract on the alloxan-induced tocicity. It could be concluded from these results that, Ehretia nancua extract should be used in manufacture processes of the natural products as functional foods or as a dietary supplement with anti-diabecretic activity as hypoglycemic effect.

Background and Aim: Caspase family genes promote degeneration and are involved in apoptotic processes. The Ziziphora clinopodioides from the mint family (Lamiaceae) is one of the plants strong with anti-inflammatory effects and involved in the process of nervous system repair. The present study aimed to determine the effects of aqueous and alcoholic extracts of Ziziphora clinopodioides on apoptosis and alteration of caspase-3 and caspase-9 gene expression after sciatic nerve compression in male rats. Materials and Methods: In the present study, 24 male Wistar rats weighing 200-250 g were randomly assigned to four groups (n=6 in each group): control, compression, treatment with aqueous, and treatment with alcoholic extracts at a dose of 75 mg/kg. The extract was injected intraperitoneally on compression day and seven days later. After 28 days, samples were taken from the lumbar spinal cord subsequent to performing the perfusion method, and the samples were studied in two ways. Thereafter, in each group, total RNA was extracted from the lumbar spinal cord, cDNA was synthesized; subsequently, the expression changes in caspases-3 and caspases-9 were compared. Results: Based on the results, the number of neurons significantly decreased in the compression group, as compared to that in the control group, and demonstrated a significant increase in the aqueous extract group, in comparison with the compression group. Furthermore, the amount of caspases-3 and caspases-9 expression increased significantly in the compression group, compared to that in the control group. Moreover, caspase-3 and caspase-9 gene expression increased in the aqueous extract group, as compared to that in the compression group (P<0.001). Conclusion: It seems that the, the extract of Ziziphora clinopodioides has neuroprotective effects due to its antioxidant and anti-inflammatory properties, as well as phenolic and flavonoid compounds, such as pulegone.

Background: Diabetes mellitus is a global health problem leading to an increase in the search for herbal normoglycaemic agents as alternative to the synthetic ones. Aqueous extract of Parkia biglobosa leaves was assessed for normoglycaemic effects in alloxan-induced diabetic rats. The study aim at providing scientific evidence to authenticate the traditional use of Parkia biglobosa leaves in the treatment of diabetes. Methodology: The plant was extracted using aqueous to obtain Parkia biglobosa Leaf Extract (PbLE), qualitative phytochemical analysis was determined using standard methods. Diabetes was induced in albino rats by intraperitoneal injection of 5% solution of alloxan (150 mg/kg bw). The rats were grouped into 5 groups (A, B, C, D and E) of 5 animals each. Group A consisted of non-diabetic rats which served as the control, Group B consisted of diabetic rats that were left untreated and served as negative control, Group C were given glucophage (reference) at a dose level of 7 mg/kg bw, Groups D and E were administered PbLE at the doses of 250 and 500 mg/kg bw respectively. Results: The glucose levels in the blood of rats were checked with a glucometer using the blood from the tail of the rats. Serum (proteins, lipid profiles, urea and creatinine), ALT, AST and ALP were all determined using standard procedures. The extract and the glucophage reduced the blood glucose level significantly (p < 0.05) from day 3 till the termination of the experiment.                                                                                                                                                Conclusion: Aqueous extract of Parkia biglobosa leaves possess antidiabetic activity and also the extract is relatively safe.  Hence the leaves of Parkia biglobosa can be explored in producing alternative antidiabetic drugs.

AbstractThe extensive use of fipronil (FPN) may trigger hazards to more than insects. The present investigation was carried out to evaluate the abrogating role of Terminalia laxiflora (TL) methanol extract (TLE) against the neurotoxic effects provoked by FPN. Fourty male albino rats were assigned into four equal groups. The first group served as control, the second one was orally administered FPN (10.5 mg/kg BW), the third group was given combination of FPN and TLE) (100 mg/kg BW), and the fourth one was orally given TLE. Our findings highlighted the efficacy of TLE as a neuroprotectant through a significant reduction in malondialdehyde (MDA) content by 25.8%, elevations of the reduced glutathione (GSH) level, catalase (CAT,) and superoxide dismutase (SOD) activities by 30.9, 41.2, and 48.2% respectively. Consequently, the relative mRNA levels of both Bax and caspase-3 were down-regulated by 40.54% and caspase-3 by 30.35% compared with the control group. Moreover, restoration of the pathological tissue injuries were detected. In conclusion, TLE proved to be a potent neuroprotective agent against the FPN-induced toxicity.

Aim: For centuries, plant and plant products have played a pivotal role in medication. This study evaluated the effect of aqueous extract of black seed (Nigella sativa) and uziza leaf (Piper guineense) on electrolytes, urea and creatinine of Wistar rats. Materials and Methods: Twenty-five Wistar rats were used for the study; the rats were arranged into five groups with five rats each. Sucrose and margarine were used to induce hyperglycemia and hyperlipidemia respectively on the rats with the exception of the rats in the positive control group.  The rats in the negative control were induced using the sucrose and margarine but were not treated using the aqueous extracts. The rats in the uziza group were treated with 2 ml of uziza aqueous leaf extract, while the rats in the black seed group were treated with 2 ml of black seed aqueous extract. The rats in the black seed & uziza leaf group were treated with 2ml of the combined aqueous extract. Results: The results showed that the extracts had a decreasing effect which was time dependent on the electrolytes. The highest decrease was obtained on the third week of feeding compared to the control (P=.05). The sodium levels (mmol/L) showed for the negative control (198.23 ± 1.96), positive control (108.15 ± 1.60), uziza leaf (98.28 ± 4.17), black seed (101.67 ± 4.24), black seed & uziza (90.83 ± 2.14).  The decrease for potassium levels (mEq/L) showed for the negative control (0.90 ± 0.06), positive control (0.05 ± 0.10), uziza leaf (0.07 ± 0.18), black seed (0.06 ± 0.19), black seed & Uziza (0.05 ± 0.10). Furthermore, the extracts also had a reducing effect on urea and creatinine levels with the highest reduction obtained on the third week (p=0.05).  The urea levels (mmol/L) showed for the negative control (26.84 ± 0.05), positive control (15.15 ± 1.20), uziza leaf (12.83 ± 0.98), black seed (12.16 ± 2.01), black seed & uziza (11.48 ± 1.78). The extracts also decreased creatinine levels (mmol/L) with the negative control (284.58 ± 0.33), positive control (182.73 ± 3.67), uziza leaf (194.16 ± 18.30), black seed (167.34 ± 14.66), black seed & uziza (174.46 ± 10.66).  Conclusion: The extracts significantly decreased the elevated electrolytes levels and therefore uziza leaf and black seed can be used to restore kidney function.
