Wistar Albino Rats

This study evaluated leucocyte mobilization and platelet aggregation effects of ciprofloxacin, lincomycin and Erythromycin in Wistar albino rats. Thirty-three female Wistar albino rats weighing 130-160 g and three male Wistar albino rats weighing 188-194 g, fed commercial growers’ mash and clean tap water were used. In leukocytes assay, thirty-three adult female Wistar rats were assigned into five treatments, eleven groups of three rats per group. First three groups were treated 10 mg kg-1, 20 mg kg-1 and 40 mg kg-1 of ciprofloxacin, next three groups same doses of lincomycin, next three groups same doses of Erythromycin, the tenth group received Indomethacin 5 mg kg-1 (reference drug), the last group 5 mg kg-1 normal saline. Assay on platelet aggregator activity involved collection of blood samples (10 ml each, 1% EDTA, centrifuged at 3000 rpm for 10 minutes), test drugs dissolved in 1 mg/ml distilled water and   Indomethacin (the reference drug). The three antibiotics significantly reduced leucocyte mobilization into the affected tissue. They all had their maximum inhibitory effects at the highest dose (40 mg kg-1) compared with indomethacin. Erythromycin 40 mg kg-1 showed the highest inhibitory effect on leucocyte migration. Whereas ciprofloxacin and erythromycin had stepwise increase in absorbance from time 0 secs through to time 120 secs, lincomycin showed a sharp decrease in the absorbance at around 30 seconds followed by a continuous increase up to 120 seconds. The testing drugs prevented leukocyte mobilization also had stepwise increase in absorbance from time 0 secs through to time 120 secs in platelet aggregatory activity assay to some extent.

This research aims to investigate the antioxidant property and oral glucose tolerance of stem extract of Andrographis paniculata using standard methods. The antioxidant activity of the extracts were assessed using total phenol, total flavonoid, ABTS (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)), nitric oxide, GSH (gluthatione), super oxide, DPPH [1,1-di-phenyl-2-picryl hydrazyl] and ascorbic acid.  The oral glucose tolerance of methanol stem extract of A. paniculata was carried out using wistar albino rats. The Wistar albino rats were divided into six groups consisting of five rats each.  Group 1 was given water only, group two to group five were induced with 2g/kg of glucose. After 30 minutes, group 3 and 4 were treated with the doses of 15 mg/kg and 30 mg/kg of the extract while group 5 was treated with glibenclamide respectively. The blood glucose level of each group was monitored for 2hours at 30 minutes interval and compared with the control that was given water only. The result shows that the extracts were able to scavenge free radicals but methanol stem extract of A. paniculata performed better in scavenging free radicals as compared to others. The blood sugar levels of the rats treated with doses of 15 and 30 mg/kg of methanol stem extract of A. paniculata were significantly lower than the group of rats that were fed with only glucose and the group of rats treated with glibenclamide. The glucose-lowering efficiency of the extract was between 60-120 minutes. Findings from this present study revealed that A. paniculata is a potential plant that can scavenge free radicals and also possess hypoglycemic activity.

The Impact

To assess the roles of dietary protein (Pr) and calcium (Ca) level associated with excessive fluoride (F) intake and the impact of dietary Pr, Ca, and F on thyroid function, 144 30-day-old Wistar albino rats were randomly allotted to six groups of 24 (female:male = 1:1). The six groups were fed (1) a normal control (NC) diet (17.92% Pr, 0.85% Ca = NC group); (2) the NC diet and high F (338 mg NaF [=150 mg F ion]/L in their drinking water = NC+F group); (3) low Pr and low Ca diet (10.01% Pr, 0.24% Ca = LPrLCa group); (4) low Pr and low Ca diet plus high F = LPrLCa+F group; (5) high Pr and low Ca diet plus high F (25.52% Pr, 0.25% Ca = HPrLCa+F group); and (6) low Pr and high Ca diet plus high F (10.60% Pr, 1.93% Ca = LPrHCa+F group). The areas of thyroid follicles were determined by Image-Proplus 5.1, and triiodothyronine (T3), free T3 (FT3), thyroxine (T4), and free T4 (FT4) levels in serum were measured by radioimmunoassay. The histopathological study revealed obviously flatted follicular epithelia cells and hyperplastic nodules, consisting of thyroid parafollicular cells that appeared by excessive F ingestion, on the 120th day. Pr or Ca supplementation reverses the F-induced damage in malnutrition. The serum T3, FT3, T4, and FT4 levels in the NC+F group were significantly decreased and significantly increased in the LPrLCa+F group. Thus, excessive F administration induces thyroid dysfunction in rats; dietary Pr and Ca level play key roles in F-induced thyroid dysfunction.

Critical Bone Defects

The high costs and extensive time needed for the treatment of critical-sized bone defects are still major clinical concerns in orthopedic surgery; therefore, researchers continue to look for more cost and time-effective methods. This study aims to investigate the effects of a decellularized omentum scaffold with a combination of platelet-rich plasma (PRP) and mesenchymal stem cells on the healing of critical-sized bone defects. Wistar albino rats (n = 30) were investigated in five groups. Critical-sized bone defects were formed on bilateral radius shafts. No scaffold, decellularized omentum, omentum with PRP and omentum + mesenchymal stem cells was used in group 1 (control group), 2, 3 and 4, respectively. In addition, omentum with a combination of mesenchymal stem cells +PRP was used in group 5. After 6 weeks, both radiological and histological healing were evaluated comparatively among the groups. After the use of a decellularized omentum scaffold, vitality of new cells was maintained, and new bone formation occurred. When compared to the control group, radiological healing was significantly better (p = 0.047) in the omentum and omentum + PRP-treated groups. Furthermore, histological healing was better in the omentum and omentum + PRP-treated groups than the control group (p = 0.001). The use of a decellularized omentum scaffold is suitable in the healing of critical bone defects.

Aim: The current study determined phytochemical constituents evaluated the acute and sub-chronic toxic profiles of Lannea acida methanol leaves extract (LAMLE) in Wistar albino rats Methodology: The phytochemical screening of LAMLE was conducted using standard methods. A total of 31 male albino rats were used for the antioxidant studies. A total of 31 male albino rats were used for the toxicological study. The LD50 was determined using six (6) rats according to OECD, 2001 using fixed limit dose. For the sub-chronic study, the rats were divided into five (5) groups of five (5) rats. Control group (group 1) received distilled water orally 2ml/kg. Groups (2-5) received doses of 250, 500, 1000, 2000 mg/kg of the extracts. The experiment lasted for 28 days. Results: The phytochemical screening revealed the presence of Flavonoids, Phenols, Tannins, Saponins, Alkaloids and Steroids. The LD50 of the extract was found to be greater than 5000mg/kg. There were significant reduction in the concentration of ALT, ALP and ALB (P<.05) in the group that received the highest dose of the extract when compared to the normal control while other liver biomarkers were not significantly different (P>0.05) from the control. The sub-chronic dose of 2000mg/kg of the extracts shows significant (P<.05) decrease in all kidney function biomarkers except chloride when compared to the control. The haematological parameters (WBC, RBC, HGB, Neutruphils) showed a significant decrease in Group 5 when compared to the normal control group while MCV and lymphocytes showed significant decrease (P<.05) when compared to the control.   Conclusion: The result suggests that the methanol leaves extracts of Lannea acida is relatively safe and can be used in medicinal formulations.

Most of the mobile phones in Turkey emit 900 MHz radiation which is mainly absorbed by the skin and, to a lesser extent, muscle. The aim of this study was to investigate the effects the 900 MHz electromagnetic irradiation emitted by these devices on the induction of histopathologic changes in skin and the effect of melatonin (Mel) on any of these changes. Thirty male Wistar-Albino rats were used in the study. The experimental groups were composed of: a nontreated control group, an irradiated group (IR) without Mel and an irradiated with Mel treatment group (IR + Mel). 900 MHz radiation was applied to IR group for 10 days (30 min/day). The IR + Mel group received 10 mg/kg per day melatonin in tap water for 10 days before irradiation. At the end of the tenth day, the skin graft was excized from the thoraco-abdominal area. Histopathologic changes in skin were analyzed. In the IR group, increased thickness of stratum corneum, atrophy of epidermis, papillamatosis, basal cell proliferation, increased granular cell layer (hypergranulosis) in epidermis and capillary proliferation, impairment in collagen tissue distribution and separation of collagen bundles in dermis were all observed compared to the control group. Most of these changes, except hypergranulosis, were prevented with melatonin treatment. In conclusion, exposure to 900 MHz radiation emitted by mobile phones caused mild skin changes. Furthermore, melatonin treatment can reduce these changes and may have a beneficial effect to prevent 900 MHz mobile phone-induced rat skin changes.

This study assessed the probable effects of Ethanolic extract of Tanacetum parthenium (EETP) whole plant as hepatoprotective compound that acts on damaged liver due to administration of Sodium arsenite (NaAsO2  — 3mg/kg) in Wistar albino rats for a period of 28 days which results in alteration in Lipid peroxidation, antioxidant enzymes, biochemical factors, and liver enzyme. 30 animals were utilized for the study and are divided into five groups containing 6 rats each. Group –I treated as control received water, Group II-V were treated with sodium arsenite. Group-III received Vitamin-E (reference drug), Group IV treated with EETP 200 mg/kg dose and Group V treated with 400 mg/kg dose after hepatotoxicity induced by Sodium arsenite. Safeguarding effects of Ethanolic extract of Tanacetum parthenium whole plant were screened by analysis of the parameters like alanine transaminase, aspartate transaminase, alkaline phosphatase and total bilirubin, malondialdehyde, antioxidant enzymes. It was explored that administration of EETP at different doses could significantly decrease the enzymatic measures of AST, ALP, ALT, and TB concentration and increase catalase, GSH, GR and GPx levels in comparison with Sodium arsenite-induced control group. The data obtained from this experimental study prefigured the antioxidant potential of EETP and its potential hepatoprotective effects, and its beneficiary therapeutic effects on vandalization or disfigurement of liver due to Sodium arsenite induction in experimental animals.

The in vivo effect of oral administration of varying concentrations (150, 250, 500 mg/kg body wt) of sodium benzoate (a known preservative in the food, cosmetic and pharmaceutical industry) on serum liver marker enzyme activity and electrolyte levels of wistar albino rats were investigated. The oral intake was administered at 24 hour intervals for 7, 14, 21 and 28 days. The groups were labeled; control (group 1), 7days (group 2), 14days (group 3), 21 days (group 4) and 28days (group 5). The rats were fed normal diet ad libitum and blood sample for the determination was taken at the end of the duration. For serum electrolytes, the result obtained for sodium benzoate concentrations administered showed significant (p≤0.05) increase in sodium (Na+) for groups 3, 4 and 5 for 150 mg/kg body wt. and group 2, 3, 4 and 5 for 250 mg/kg body wt and 500mg/kg body wt. of experimental rats. Chloride (Cl-) showed significant (p≤0.05) increase at all administered groups for 250 mg/kg and 500mg/kg. Potassium (K+) was only significantly increased at group 5 for 500mg/kg body wt. while for bicarbonate (HCO3) it showed no significant change in all treated groups. Values were all compared to the control. For liver marker enzymes, sodium benzoate significantly increased (p≤0.05) aspartate transaminase (AST) activity of experimental rats in groups 2, 3, 4 and 5 of 250 mg/kg body wt. and 500mg/kg body wt., alanine transaminase (ALT) showed significant increase (p≤0.05)  in group 4 and 5 for 250 mg/kg body wt and group 2, 3, 4 and 5 for 500 mg/kg body wt., alkaline phosphatase (ALP) showed significant (p≤0.05) increase in group 2, 3, 4 and 5 for 500 mg/kg body wt.These findings suggest possible changes in blood chemistry due to the preservative.

Antianemc potential of aqueous of Justicia galeopsis leaves was studied using Wistar Albino rats after induction of anemia by phenylhydrazine hydrochloride. Forty rats (20 male and 20 female) subdivided into five groups of eight rats were used. There was a group as control (not anemic) and four other anemic groups which had received by gavage respectively 1 ml/kg of distilled water, 1 ml/kg of body weight of Vitafer (reference drug commonly used to treat anemia), 100 mg/kg of body weight of extract of J. galeopsis leaves cooked during 30 min and 30 mg/kg of body weight of extract of J. galeopsis leaves cooked during 45 min. Hematological parameters (red blood cells, hemoglobin and hematocrit) were analyzed as indices of anemia and the weights of specific organs (liver, spleen and kidney) were evaluated. The results of this investigation had showed that aqueous extract of J. galeopsis leaves cooked improved red blood cells, hemoglobin and hematocrit levels. These extracts were not toxic for liver, spleen and kidney. The administration of 100 mg/kg/day of extract of leaves cooked leaves during 30 min promotes a better recovery rate of the number of red blood cells (94.80 %), hemoglobin level (159.53 %) and hematocrit (117.72 %) than Vitafer and the extract of leaves cooked for 45 min. This is suggestive that aqueous extracts of Justicia galeopsis leaves cooked during 30 min may be exploited during 2 weeks in the treatment of anemia.

This study aimed to investigate whether berberine nanoparticles (BBR-NPs) and/or cisplatin supplementation could prevent hepatocarcinogenesis-induced by N-nitroso-diethylamine (DENA) in male rats. Male Wistar albino rats were divided into five groups; Group 1: Control; Group 2: DENA-CCl4; Group 3: DENA-CCl4+Cisplatin; Group 4: DENA-CCl4+BBR-NPs; Group 5: DENA-CCl4+Cisplatin+BBR-NPs. DENA-CCl4 significantly increase AST, ALT, ALP, LDH, GGT, AFP activities and total bilirubin, while, 5, NT,  total protein and albumin decreased. DENA-CCl4 treatment caused increment in MDA levels and reduction in SOD, CAT, GPx and GSH in liver tissues. Moreover, DENA-CCl4 increase the gene expression of ADAM17 and TNF-α however,  P53 was declined. In addition, DENA-CCl4 caused severe histopathological lesions in the liver tissue. Interestingly, administration of berberine nanoparticles alone or in combination with cisplatin improves the hepatocarcinogenesis induced by DENA-CCl4 on the physiological, biochemical, molecular and histological levels by decreasing oxidative stress and preserving gene expression of ADAM17, TNF-α and P53. The present findings suggest that BBR-NPs with cisplatin might offer a promising strategy for the prevention of liver cancer.
