Red Dye

Nowadays synthetic food dyes are mostly preferred than natural plant derived dyes due to low cost and intense coloration. In this study hematological and biochemical parameters were determined in male wistar rats after 30 days treatment with synthetic red dye orange red and natural plant derived red dye alizarin. 25 male wistar rats were divided into 5 groups with 5 animals per group. Group I rats were taken as control treated with normal rat diet and distilled water. Group II and III rats (experimental) were oral gavaged with 50 mg and 150 mg/kg body weight of alizarin dye. Group IV and V rats (experimental) were gavaged with 50 mg and 150 mg/kg body weight of orange red dye. Treatment of group V rats with 150 mg/kg body weight of orange red dye produce significant changes in RBC, Hb, Hct, MCH, serum aminotransferase enzymes and serum protein fraction. In comparison to this in group IV rats a significant change was observed only in Hb, serum aminotransferase enzymes and serum protein fraction when compared with control (group I) rats. However in group II and III alizarin treated rats no significant change was observed in different biochemical and hematological parameters relative to their respective control. In conclusion synthetic orange red dye proved to be more toxic than natural plant derived red dye alizarin.

Aims: To study the protective effect of hydroalcoholic bark extract of Terminalia arjuna against DBTC induced pancreatic cancer in male wistar rats. Study design: Healthy male Wistar Albino rats weighing 150-200 g were segregated into four groups (n=6). Group I was considered as normal control, received normal saline (0.9%w/v, 1 ml/kg body weight, orally). Group II rats were treated with DBTC (6 mg/kg body weight, i.p.) which served as negative control. Group III and IV received Terminalia arjuna Linn bark hydroalcoholic extract at doses of 250 mg/kg body weight, per oral and 500 mg/kg body weight, per oral respectively. Place and Duration of Study: University College of Pharmaceutical Sciences, Andhra University, Visakhapatnam, Andhra Pradesh, India, between May 2020 and July 2020. Methodology: The experimental animals were segregated into four groups of six rats each. According to acute toxicity data, 250 mg/kg as low dose and 500 mg/kg as high dose of the test compound have been chosen for administration. All the drugs were given for 28 consecutive days to all the respective groups with standard pellet diet and water ad libitum. The assessment of serum parameters such as α-Amylase, Lipase and blood glucose levels were carried out on 1st day, 14th day and 28th day to the respective groups. Results: Pretreated groups of Terminalia arjuna Linn bark hydroalcoholic extract (250 mg/kg and 500 mg/kg body weight, orally) showed significant (‘#’p<0.001) decrease in the levels of α-Amylase, Lipase and glucose in the blood when compared to DBTC (6 mg/kg body weight, i.p.) induced group which served as negative control. Conclusion: This study suggests that Terminalia arjuna may have a protective role against DBTC induced pancreatic cancer in male wistar rats and further investigation may be required to confirm its therapeutic potentials clinically.

Introduction: The use of antiepileptic drugs (AEDs) such as carbamazepine and phenytoin are part of strategies for the management of epilepsy. Acute exposure of epileptic patients to AEDs can cause sensory impairment. Aim: This study seeks to assess sensorimotor changes in male Wistar rats upon single-large dose exposure to carbamazepine, phenytoin and their mixture. Methods: 24 male Wistar rats (160-210 g) were randomly separated to four groups with 6 rats each. Groups I, II and III was given distilled water (2 ml/kg), carbamazepine (1950 mg/kg); and phenytoin (820 mg/kg) respectively, while Group IV (CBZ+PHY) was co-exposed to carbamazepine (1950 mg/kg) and phenytoin (820 mg/kg). The treatment was orally administered once by gavage (on Day(D) 1), then followed by weekly monitoring of body weight, clinical signs and neurobehavioural parameters for four weeks (D0, D1, D7, D14, D21 and D28). Results: The body weight revealed insignificant improvement (p > 0.05) in all groups. A significantly (p < 0.05) lower grooming frequency, increased locomotor activity and a reduction in the frequency of urination and defecation were recorded in the CBZ and PHY groups. Also, the number of missed rungs, inclined plane and grip fore-paw time reduced significantly (p < 0.05) in CBZ, PHY and CBZ+PHY groups. Significance: A single large dose of CBZ, PHY and their combination caused anxiogenic and sensorimotor impairment.

Hepatotoxicity caused by chemotherapeutic drugs (e.g., doxorubicin) is of critical concern in cancer therapy. This study focused on investigating the modulatory effects of diosmin against doxorubicin-induced hepatotoxicity in Male Wistar rats. Male Wistar rats were randomly divided into four groups: Group I was served as control, Group II was treated with doxorubicin (20 mg/kg, intraperitoneal, i.p.), Group III was treated with a combination of doxorubicin and low-dose diosmin (100 mg/kg orally), and Group IV was treated with a combination of doxorubicin and high-dose diosmin (200 mg/kg orally) supplementation. A single dose of doxorubicin (i.p.) caused hepatic impairment, as shown by increases in the concentrations of serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Doxorubicin produced histological abnormalities in the liver. In addition, a single injection of doxorubicin increased lipid peroxidation and reduced glutathione, catalase, and superoxide dismutase (SOD) levels. Importantly, pre-treatment with diosmin restored hepatic antioxidant factors and serum enzymatic activities and reduced the inflammatory and apoptotic-mediated proteins and genes. These findings demonstrate that diosmin has a protective effect against doxorubicin-induced hepatotoxicity.

Abstract Objectives Exposure to light-at-night (LAN) has been reported to impair blood glucose regulation. The liver modulates blood glucose through mechanisms influenced by several factors that include peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1α) and glucose-6-phosphatase (G6Pase). This study investigated the effect of intermittent exposure to green and white LAN on some hepatic glucose regulatory factors in male Wistar rats. Methods Animals were divided into three equal groups. Group I (control) was exposed to normal housing conditions. Groups II and III were each daily exposed to either green or white LAN for 2 h (7–9 pm) for 14 days. Body weight and blood glucose was monitored on days 0, 7, and 14. Thereafter, retro-orbital sinus blood was obtained after light thiopental anaesthesia and serum insulin was determined. Liver samples were also obtained and evaluated for glycogen, PGC-1α, and G6Pase activity. Insulin resistance was estimated using the HOMA-IR equation. Results Body weight and blood glucose on days 7 and 14 increased in groups II and III compared to control. Hepatic PGC-1α and G6Pase increased in group II (2.33 ± 0.31; 2.07 ± 0.22) and III (2.31 ± 0.20; 0.98 ± 0.23) compared to control (1.73 ± 0.21; 0.47 ± 0.11). Hepatic glycogen was 71.8 and 82.4% reduced in groups II and III compared to control. Insulin in group II increased (63.6%) whiles group III values reduced (27.3%) compared to control. Insulin resistance increased in group II (0.29 ± 0.09) compared to control (0.12 ± 0.03) and group III (0.11 ± 0.03), respectively. Conclusions Exposure to 2 h green and white LAN in the early dark phase increases hepatic glycogenolysis and gluconeogenetic activities resulting in increased blood glucose. In male Wistar rats, exposure to green but not white LAN may predispose to insulin resistance.

Objective: The objective of the study was to study the silymarin’s pancreatoprotective effect in alloxan-induced Type I diabetes mellitus. Numerous studies have evidence to prove the fact that antioxidant defense mechanism of flavonoids has overcome the progression of chronic diabetic complications. Methods: A total of 24 male Wistar rats were divided into four groups (n=6): Group I normal control, Group II, Group III, and Group IV were induced diabetes with alloxan. Group I and Group II diabetic rats received the vehicle (PO). Group III was treated with silymarin 400 mg/kg (PO). Group IV was treated with glibenclamide 0.5 mg/kg, per orally for 21 days. Fasting blood samples were collected from all four groups of animals at the end of 21 days to evaluate serum glucose and glycosylated hemoglobin (HbA1c). Pancreatic tissue extraction, to perform lipid peroxidation and histopathological study confirms the level of oxidative damage to tissues and recovery after treatment. Results: The serum glucose and HbA1c levels significantly increased in untreated diabetic rats, also a significant rise in lipid peroxidation and necrosis of beta cells in the pancreatic tissue. The rise in serum glucose levels was ameliorated in rats treated with silymarin, pancreatic tissue showed increased antioxidant levels, decreased lipid peroxides, and minimal changes and signs of regeneration of beta cells. Conclusion: This study adds experimental evidence to the fact that silymarin is an effective nutritional supplement to treasure pancreatic beta-cell reserve and to delay diabetic complications.

Abstract. This study was designed to investigate the hepatorenal protective effects of trévo, on cadmium-induced renal and hepatic injury in male Wistar rats. Methods. Fifteen healthy male Wistar rats were divided into three groups of five rats per group. Group I (control); group II (35mg/kg cadmium chloride (CdCl2); Group III (2 ml/kg trévo+ CdCl2. The rats were treated with trévo (2ml/kg orally) and administered CdCl2 3 hrs later. Twenty-four hours after the last administration rats were sacrificed and blood was collected via cardiac puncture and processed for hematological parameters and assessment of urea, creatinine (CREA), and uric acid (UA), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and albumin (ALB). The liver and kidney were excised and processed for markers of oxidative stress. Results intraperitoneal administration of 35 mg/kg of CdCl2 caused a significant increase in serum concentration of urea, CREA, UA, AST, ALT, while the concentration of ALB was significantly lower (P<0.0001). CdCl2 caused a significant reduction in packed cell volume, hemoglobin while the total white blood cell count, neutrophils, lymphocytes, monocytes, eosinophils, and basophils were increased. Oxidative stress was significantly pronounced in the liver and kidney of rats exposed to CdCl2 as observed in the high concentration of malondialdehyde, decreased concentration of glutathione, the activity of catalase, superoxide dismutase, and glutathione-S-transferase. Pretreatment with trévo was able to significantly prevent the anemic, oxidative damage, renal and hepatic injury initiated by CdCl2. Conclusions. The study reveals that trévo is effective in attenuating cadmium-induced hepatorenal toxicity in male Wistar rats.

The Impact

Abstarct Polyherbal compound (Bronco-T) has been extensively used as a traditional medicine for various therapies. However, very few report studies on anti-inflammatory and lung regeneration properties are evidenced. In the present study, we evaluated the beneficial actions and anti-inflammatory properties of polyherbal medicine, Bronco-T, exhibited by treating the lungs of rats exposed to formaldehyde to evaluate the beneficial properties. For this study, we divided into five groups’: i.e. Group-I served as a control and the other four groups such as II, III, IV, and V are experimental. All animals maintained by regular feed and water ad libitum during the study. Formaldehyde vapors exposure at a single period of time (1 hour) daily (40%formaldehyde at room temperature) for 21 days period exposed all groups. The Bronco-T extracts about 50 mg/kg BW administered to experimental groups and group IV rats treated with 500μ grams/Kg BW salbutamol. To understand the impact of formaldehyde exposure on the beneficial effects of Bronco-T, we evaluated hematological parameters, bronchoalveolar lavage (BAL), histamine levels, and histological alterations of lung architecture. Formaldehyde-induced adverse effects in lung and increased histamine levels in BAL compared to Bronco-T-treated rats act as a preventive immunological role in blood toxicity and recovery of lung architecture in Bronco-T-treated rats. This study showed the evaluation of antihistamine levels through HPLC analysis. Bronco-T has antioxidant and anti-histamine properties as the widest therapeutic window, and we continue to evaluate the pharmacological evaluations needed in our further studies.
