Wistar Albino Rats

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.

<p class="abstract"><strong>Background:</strong> Nowadays, cyclophosphamide is widely used as anticancer and immunosuppressive agent in various drug regimens in many diseases and in young and old age. The aim of this research is to study the possible histological changes that may occur in the testes of adult male albino rats as a result of chronic exposure to cyclophosphamide and the prognosis of this effect.</p><p class="abstract"><strong>Methods:</strong> Thirty healthy adult male albino rats were used in this study.  They were equally divided into three groups; a control, an experimental and a withdrawal groups. The Animals of the experimental group were treated with daily dose of 5 mg/ kg cyclophosphamide orally for successive 28 days. Animals of the withdrawal group were left without treatment and sacrificed after 28 days from the last dose of cyclophosphamide.  At the time of sacrifice, all animals were anesthetized by ether inhalation and their testes were dissected out carefully and processed for light and electron microscope examinations<span lang="EN-IN">. </span><span lang="EN-IN"> </span></p><p class="abstract"><strong>Results:</strong> Testes of the cyclophosphamide treated group revealed presence of many distorted shrunken seminiferous tubules which appeared with marked reduction in the thickness of the epithelium and wide lumina. Many germ cells with deeply stained nuclei, giant cells in mitosis and intracellular vacuoles were observed. Cross sections in mid pieces of sperms showed marked affection of axoneme, fibrous sheath and mitochondrial sheath. The cytoplasm of the Leydig cells contained mitochondria, dilated SER, Golgi cisternae and RER. Testes of the withdrawal group showed that the seminiferous tubules still had reduced height of their epithelium with wide intercellular spaces. Abnormal stratification and destructed germinal epithelium were evident with desquamated germ cells. Cross sections of mid pieces of the sperms showed distorted axoneme and swollen mitochondrial sheath. The cytoplasm of leydig cells contained many electron dense granules, RER, many dilated SER and mitochondria.</p><p class="abstract"><strong>Conclusions:</strong> Chronic cyclophosphamide treatment not only produced serious histological changes of the testis but also in its serological parameter. These changes persisted after cessation of cyclophosphamide administration which indicates the cumulative irreversible toxic effect of cyclophosphamide. So, it is advisable to avoid the usage of cyclophosphamide as possible especially in young patients<span lang="EN-IN">. </span></p><p class="abstract"> </p>
