The present investigation was aimed to determine the effect of sub-chronic exposure to Solignum<sup>®</sup>, a permethrin-containing wood preservative on biochemical and histological changes in liver and kidneys of male Wistar albino rats. Thirty-two male rats were randomly divided into four groups: control and three treatment concentrations containing 8 rats each. The treatment groups were exposed to Solignum<sup>®</sup> at dose rates of 100, 200 and 400 mg/kg body weight (BW) respectively per day orally for four weeks. Data obtained from the study showed a progressive increase in the body weight of rats in control whereas, rats treated with different concentrations (100, 200 and 400 mg/kg BW) of Solignum<sup>®</sup> decreased significantly (≤0.05) especially at the end of the second and fourth week when compared with control. On the other hand, there was a significant decrease in the relative liver weights of rats treated with 100 and 200 mg/kg BW Solignum<sup>®</sup> while rats treated with 400 mg/kg BW showed a significant increase when compared with control. The relative weight of kidneys in experimental groups increased significantly when compared with control. Biochemical analysis results illustrated that there was a significant increase in marker enzymes namely alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase activity at the end of the fourth week. Similarly, total bilirubin, serum urea, creatinine and electrolytes (Na<sup>+</sup>, K<sup>+</sup> and Cl<sup>-</sup>) levels increased in a dose dependent manner in treated rats when compared with untreated control group. Serum total protein decreased significantly in experimental rats when compared with control. However, cholesterol and triglycerides showed no significant difference when compared with control. Histopathological examination of hepatocytes in treated rats was characterized by mild periportal inflammatory cells and cytoplasmic degeneration. Furthermore, histopathological examination of rat kidneys revealed inflammatory cells, congested vessel and interstitial hemorrhage in rats treated with Solignum<sup>®</sup>. Therefore, this present study is aimed to evaluate the hepatotoxic and nephrotoxic potentials associated with sub-chronic exposure to the commercial pesticide Solignum<sup>®</sup>.

Membrane Bound Enzymes

Membrane bound adenosine triphosphatases (ATPases) shed a massive function into the contraction and relaxation of the heart muscle via keeping the normal ion levels within the myocyte. The current study aims to assess the potency of Zanthoxylum armatum (Z. armatum) fruit on membrane bound ATPases and ions in Isoproterenol (ISO) induced myocardial infracted rats. The hydroethanolic extract of Z. armatum fruit was administered at a dose of 200 and 400mg/kg body weight for 30 days to male Wistar albino rats. On 28th and 29th day, ISO (8.5mg/100g body weight) used to be administered to induce myocardial infarction (MI). ISO treated rats confirmed a significant increase in the levels of tissue sodium (Na+) and calcium (Ca2+) ions and membrane bound Ca2+ ATPase then Mg2+ ATPase activity. A significant decrease in tissue potassium (K+), Na +/K+ ATPase was observed which indicates membrane destabilization. Pretreatment with hydroethanolic extract of Z. armatum fruit to ISO induced rats significantly (p<0.05) prevented the altered membrane bound enzymes to near normal status. The findings of the present study indicate the protective effect of Z. armatum fruit on altered ion pumps and destabilization on the cardiac membrane into ISO induced MI rats which might also be due to the presence of phytoconstituents.

The Impact

Hypericum perforatum, which is known as St. John’s wort (SJW), is a leafy herb that grows in the open areas of the temperate regions throughout the world. Recent research suggests the effectiveness of this plant in treating some diseases, such as cancer, bacterial and viral diseases, and some inflammation-related disorders, and as a neuroprotective agent and an antioxidant. The current study aimed to investigate the Impact of water and alcoholic plant extracts of H. perforatum on histological and some physiological features in the liver of albino rats. 21 male rats were used in the current study. They were divided into groups; each group contains 7 members of animals. The animals were raised a month ago in the animal house before conducting the study to ensure their suitability to the environment of the animal house. Before the start of the study, an appropriate amount of animal blood was obtained through the caudate vein of rats, in order to evaluate the variables of the physiological study before starting treatment with plant extracts. One of the groups (Group 1) was used as a standard control group, receiving only standard water and feed. The other group (Group 2) was treated with St. John's water extract at a concentration of 300 mg/kg/body weight, while the last group (Group 3) was treated with St. John's alcoholic plant extract at a concentration of 300 mg/kg/body weight. Aqueous and alcoholic plant extract were prepared for H. perforatum. Histological slides were prepared from the liver of each group of the study as well as, alkaline phosphatase (ALP), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were evaluated for the rates in each group. Histological examination shows the presence of necrosis in various stages and the presence of Foamy Cells and the occurrence of infiltration of a number of inflammatory cells within the tissue as well as the occurrence of congestion in the central vein and hemorrhage spread throughout the rest of the tissue. We also note the occurrence of necrosis and desquamation of the central vein lining and infiltration of some inflammatory cells in some areas. The effect of treatments on the aminotransferases (AST, ALT) enzymes and the ALP, where appeared as a significant increase of 0.05 in their concentration when comparing the concentrations of each groups before and after treatment with plant extracts. We can conclude that H. perforatum aqueous and alcoholic plant extract can causes mild damages on liver histological features that can be reflected on livers physiological states generally and on the ALT, AST and ALP enzymes specifically.

Sida acuta burm.f belongs to Malvaceae, the mallow family and enjoys tropical and pantropical distribution. The plant is usually known as wireweed in the countryside, and it is highly medicinally valued traditionally and ethnobotanically promised. The species have literature reports on scientific attributes like abortifacient, anthelmintic, diuretic, anti-rheumatic, antipyretic and wound healing properties. The present study is concerned with acute and sub-chronic toxicity evaluation of ethanolic extract of Sida acuta Burm.f leaves in Wistar albino rats. Acute toxicity evaluation was conducted for 14 days. Acute doses of 100, 250, 500, 1000 and 2000 mg/kg BW were administrated to test groups of animals under consideration on the first day of experimental evaluation with three animals in each of total six groups along with control. For the remaining 13 days, animals were observed for noted behavioural changes and body weight were recorded respectively for 7th and 14th day of experimental analysis. At the end of the trial period, all the animals were euthanised, and various biochemical parameters and histopathological examination were carried out to assess the toxicity of extract. The present study revealed that the ethanolic extract of Sida acuta Burm.f leaves is non-toxic up to 2000mg/kg body weight. Subchronic toxicity evaluation was conducted for 28 days with several doses 100, 200, 300, 400 and 500mg/kg BW. Control rats without any treatment were maintained during the entire period of experimental analysis. The results of subchronic toxicity parameters indicate no significant changes to the biochemical parameters (glucose, urea, uric acid, creatinine, AST, ALT and Cholesterol) haematological and histopathological observation in comparison to the control groups. Based on subchronic toxicity parameters data, effective doses (200 and 400mg/kg BW) is determined for further cancer (colon) study in Wistar albino rats.

The protective effect of natural bees' honey to the liver of male albino rats against melamine toxicity was studied. Melamine supplementation at a dose of 20000 ppm in the diet for 28 days induced adverse effects on the liver, decreased serum total protein and increased liver enzyme: alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Histological changes of the melamine supplemented group showed necrosis in the hepatic tissues around the central veins of the liver and precipitation of melamine crystals. Treating the male albino rats (that were presupplemented regularly with 20000 ppm melamine) with natural bees' honey at a dose of 2.5 g/kg body weight for 28 days improved both liver functions and increased serum protein. In addition, a positive impact on the shape of the cells after treatment with honey compared to the positive melamine supplemented group was observed. In conclusion, the results of this study revealed that the use of natural bees' honey has the ability to protect the liver of rats against the toxic effects of melamine.

  Objective: The present study explored the influence of fluoride exposure on gonadotropins and reproductive hormones.Methods: Male Wistar albino rats weighing 100-150 g were administered with 100, 200, and 300 ppm/kg body weight of sodium fluoride daily for 20 and 40 days. The control group was given 1 ml deionized water/kgbw/day for the same period. At the end of the experimental period, half of the animals were sacrificed and blood serum was collected and testis sample was taken concurrently. Remaining half rats were administrated with two doses (250 mg and 500 mg/kg body weight) of leaf extract of Boerhaavia diffusa L. for another 20 days. Serum level of follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and intratesticular level of testosterone were evaluated.Results: It was found that fluoride intoxication resulted in significant increase in the level of FSH (p<0.01) and LH (p<0.0001) while significant decrease in the serum (p<0.01) and testis (p<0.0001) level of testosterone. A significant (p<0.0001) positive correlation was found between level of serum fluoride and gonadotropins: FSH (20 days, r=0.708 and 40 days, r=0.795) and LH (20 days, r=0.779 and 40 days, r=0.891). However, there was significant (p<0.0001) negative correlation existed between serum fluoride and testosterone levels in serum (20 days, r=−0.780 and 40 days, r=−0.862) as well as testis (20 days, r=−0.915 and 40 days, r=−0.938).Conclusion: It was found that administration of B. diffusa L. alleviated the adverse effects of fluoride on reproductive endocrine functions.

Background: Cardiotoxicity (CT) can be developed due to prolonged use of higher doses of some drugs, exposure to some chemicals, toxins or infectious agents and also by some disease conditions. Natural plant foods such as peanut (Arachis hypogaea L.) may have free radical scavenging activity, thereby can be used for the prevention and management of heart disease. Objective: To observe the protective effect of peanut (Arachis hypogaea L.) and its combined action with propranolol on histological changes in isoproterenol induced cardiotoxic rats. Method: This experimental study was carried out in the Department of Physiology, Sir Salimullah Medical College, Dhaka in 2012. For this purpose, 20 Wistar albino rats, age 85- 100 days, weighing 120 to 150g (initial body weight) were included in the peanut treated group. They were sub-divided into CT-ISO-P (Cardiotoxic group with isoproterenol after peanut treatment) and CT-ISO-C (Cardiotoxic group with isoproterenol after combined treatment of peanut and propranolol). Age and weight matched 30 Wistar albino rats without any peanut supplementation were taken and sub-divided into three sub-groups, BC (Baseline control), CT-ISO (Cardiotoxic group with isoproterenol) and CT-ISO-PRO (Cardiotoxic group with isoproterenol after propranolol treatment). Each sub-group consisted of 10 rats. After taking final body weight all the rats were sacrificed on 22nd day. The heart was removed and preserved in 10% formalin for histological processing. To find out the histopathological changes of heart tissue, histological slides were prepared and were observed under microscope in the Department of Pathology, SSMC. Histological findings were categorized by scoring as mild, moderate and severe histological changes. The statistical analysis was done by one way ANOVA and Bonferroni test as applicable. Result: In this study, percent change from initial body weight to final body weight was significantly (p<0.01) lower both in CT-ISO-P and CT-ISO-C as compared to that of BC. Again, histological score was significantly (p<0.01) higher in CT-ISO in comparison to that of BC. Moreover, these scores were significantly lower in CTISO- PRO (p<0.01), CT-ISO-P (p<0.05) and CT-ISO-C (p<0.05) in comparison to that of CT-ISO. Similarly, this score was significantly (p<0.01) lower in CT-ISO-C when compared to that of CT-ISO-P. Conclusion: The present study revealed that peanut can preserve almost normal histological architecture of heart tissue in isoproterenol induced cardiotoxic rats. However, the combined therapy of peanut with propranolol showed synergistic effect on preventing histological changes in heart tissue.

Background and Aim: Tramadol is a potent analgesic effective in the treatment of mild to severe pains. However, the use of the drug can pose a threat to other organs and systems. Therefore, this study evaluated the effect of graded doses of tramadol on sperm profile of male albino rats. Materials and Methods: Eighteen male rats were divided into three groups (A, B and C) using completely randomized design (CRD) with six rats in each group. Rats in group A served as the control group and were given just food and water while groups B and C were given tramadol at 50 and 100 mg/kg body weight (BW) respectively, daily for the period of 65 days. The treatment was administered via oral gavage and at the end of the treatments, the rats were sacrificed. Immediately after sacrifice, a puncture was made in the epididymis with a sterile pin and examined for semen pH. The epididymes were processed for epididymal sperm motility, viability, count and sperm head abnormality. Results: There was no significant difference in the weight of testes and semen pH. Sperm viability, sperm motility, sperm count and weight of epididymes significantly reduced (p<0.05) in tramadol treated animals when compared with the control. Results also indicated statistically significant (p<0.05) increase in sperm head abnormalities in rats treated with tramadol when compared with the control. Conclusion: The results obtained from this study reveal that tramadol has negative effects on weight of epididymes, sperm count, sperm viability, sperm motility and sperm head abnormalities in male albino rat as mammalian models in a dose dependent manner.

The main aim of this study was to screen the selected fruit peel extracts and their polyherbal mixture (PHM) for hepatoprotective activity. Male wistar albino rats (180-200 g), divided into 12 groups after induction of hepatotoxicity, were treated with selected fruit peel extracts and PHM and at the end of 14th day blood and liver samples were collected and analysed. The aqueous peel extract of Malus pumila was a better hepatoprotective among the selected peel extracts. The activities might be due to the conditioning of hepatocytes by protecting the integrity of the membrane from CCl4 induced leakage of serum markers into circulation. All the selected plant extracts and PHM were shown to revert back the liver enzymes to the normal values in diseased rats in a dose dependent manner. In conclusion, the selected fruit peel extracts and poly herbal mixture can be a potent hepatoprotective agent due to their antioxidant and anti-inflammatory actions.

Objective: The objective of this study is to assess the activity of Ulva lactuca polyphenols fraction in protecting the myocardial infarction induced by a high dose of isoproterenol. Methods: This study was carried out using Wistar albino rats divided into six groups. Group 1 was the normal group. Groups 2, 3, 4, 5, and 6 received isoproterenol (85 mg/kg) i.p. twice at an interval of 24 h on the 14th and 15th day. In addition to isoproterenol, Group 3 received verapamil (5 μmol/kg) as a single dose intravenously on the 14th day 10 min before isoproterenol and Groups 4, 5, and 6 received U. lactuca polyphenols fraction at the doses of 50, 100, and 200 mg/kg, respectively, for 14 days. On the 16th day, serum and heart samples were harvested from the animals and the cardioprotective and antioxidant activities were assessed by studying the levels of cardiac functional heart marker enzymes, lipid profile, reduced glutathione, and antioxidant enzymes. Results: U. lactuca polyphenols fraction, at the tested doses, restored the levels of all serum markers and enzymes (aspartate aminotransferase, alanine aminotransferase, creatine phosphokinase, lactate dehydrogenase, cholesterol, triglycerides, and reduced glutathione) and heart homogenate antioxidant markers (reduced glutathione, superoxide dismutase, catalase, and glutathione peroxidase) significantly, in dose-dependent manner. Conclusion: This study suggests that U. lactuca polyphenols fraction has a cardioprotective effect against isoproterenol-induced myocardial infarction and possess antioxidant activities.
