The liver is critical organ for metabolic homeostasis and toxic substance clearance and plays an important role in the systemic response to critical illness. Acute panreatitis (AP) progresses with a local production of inflammatory mediators, eventually leading to systemic inflammatory response syndrome. Knowing that almost all pancreatic mediators released from the pancreas to the blood stream may pass through the liver before their dilution in the systemic circulation, it would be reasonable to assume a determinant role of this organ in development of the inflammatory response associated with acute pancreatitis. Objectives: The study aimed to investigate the time courses of the effects of the exogenous glucocorticoids agonist dexamethasone on microscopical changes occurring in the liver of rats used as a model of AP induced by L-Arginine. Materials and Methods: 60 adult male albino rats weighing 150-200 gm were used. They were divided into 3 groups: Control group: Which is also divided into 2 subgroups (a & b) each of animals of the first were IM injected with 0.5ml/100gm B.W saline and those of second were injected by 0.5mg/100gm B.W dexamethasone. L-Arginine group: which received L-Arginine to induce AP. The animals of this group were divided into 3 subgroups a, b and c the animals of which were sacrificed 3 days, 2 weeks and 1 month after L-Arginine injection respectively. Dexamethasone and L-Arginine group: in which the animals were injected with both L-Arginine and dexamethasone. They were also divided into 3 subgroups a, b and c, the animals of which were sacrificed 3 days. 2 weeks, one month after the injection of the drugs. The liver of the scarified animals were dissected out and prepared for microscopical examination. Results: The histopathological changes that occurred in the livers of acute pancreatitis (AP) model animals started in the periphery of the classic hepatic lobules and progressively extended in a centripetal manner to involve all the cells of the lobules in the late period of the experiment. These changes were in the form of ballooning of the hepatocytes, progressive vacuolation of their cytoplasm most propably with fat globules and depletion of the PAS+ve glycogen granules. Injection of dexamethasone in AP model animals did not improve the case, but on the contrary it made the changes more intense, severe, and rapid. One month after injection of L-Arginine and dexamethasone, the hepatocytes all over the hepatic lobules were severely affected. They were markedly ballooned with severely vacuolated cytoplasm which was completely depleted from its PAS +ve glycogen granules, indicating severe fatty degeneration of the liver. Conclusion: From the previous data, it can be concluded that treatment of AP with dexamethasone is caused a late bad effect on the liver, where it causes its late fatty liver changes.Full article

In this review proteins associated with tight junctions (TJs) is described with an emphasis on prostate cancer. Overall tight junctional proteins do not seem to play a decisive role in prostate carcinoma pathogenesis. Of TJ proteins, expression of some claudins show an association with clinical behaviour of the tumors. Claudin 1 expression appears to be related to a better prognosis partly due to its involvement in EMT abrogation. Claudin 3 and 4 are highly expressed in prostate cancer and their expression is associated with aggressive behaviour. Inhibition of claudin 8 promotes prostate carcinoma invasion and spread but studies are few. CPE has been known to bind to especially claudins 3 and 4 and cause cell lysis. Several experiments with modified CPE have been made in prostate cancer cell lines. Regardless of this effective CPE based human treatment for prostate cancer have not yet been developed.Full article

The purpose of this study was to examine the Free Sanitary Pad Intervention Programme for Girls’ Education and School Retention in Tolon District in the Northern Region of Ghana. Quantitatively, a descriptive cross-sectional research design was adopted for the study. The study population consist of female menstruating school adolescent girls from these five St, Monica’s R/C, Nyankpala D/A, Nizamia E/A, Islamia E/A and Nawaria E/A junior high schools between the ages of 10 to 22 years who were beneficiaries of CAMFED intervention programmes in the Tolon district. A homogeneous purposive sampling technique was used to select the five junior high schools and the one-hundred and fifty (150) adolescent girls in their menstrual cycle stage. The main instrument for data collection was a semi-structured questionnaire. The data entry and analysis were done by using the SPSS version 20 software package. The data was edited, coded and analysed into frequencies, percentages with interpretations. The study concluded that, there were frequent distribution of free sanitary pads among the beneficiaries’ schools. The study also indicated that the education given to the respondents during the distribution of the free sanitary pads led to improved menstrual hygiene management practices. It is recommended that, schools within the Tolon district should put in place the necessary and adequate toiletry and disposal systems to ensure menstrual hygiene among students especially, girls, during that time of the month. It is also recommended that, Government should make it a priority to provide every school with some sanitary products and drugs to cater for the female student taken by surprise with her monthly flow or the pain associated with mensuration not interfering with her academic work.Full article

The purpose of the study was to evaluate of Social Studies Teachers Knowledge in Nature, Goals, and Objectives in the Lesson Presentations The study adopted qualitative research approach. Data were collected through the use of individual interviews, observation and focus group discussions for triangulation purposes. Purposive, convenient and simple random sampling techniques were used to select the schools, teachers for the study. In all, seventeen (17) Social Studies teachers were selected from six (6) Senior High Schools. The study revealed that teachers were grossly deficient about the goals of Social Studies. To improve this system, it is recommended that the researchers suggests that the highest priority should be given to the training and development of a new breed of educator who are vocationally competent and academically sound. This can be done by heads of institutions to allow teachers who specialise in their respective areas to teach those subject areas at the various levels of education particularly Social Studies at the High school level.Full article

The therapeutic effect of Cyclophosphamide (CPA) is thus attributed to phosphoramide mustard and acrolein leads to the formation of high levels of reactive oxygen species (ROS), which results in decreased antioxidant activity. Excessive production of ROS could also culminate in oxidative stress. Objectives: This study aims to evaluate the effect of sub-lethal dose of the cyclophosphamide, 5-FU, combination of 5-FU, and CPA on testicular antioxidant status, and oxidative stress in male albino rats. Materials and Methods: Twenty-eight male adult rats were grouped randomly into four groups (n=5 each group). Group I (control): Rats were injected with saline intraperitoneally and at a dose of 1.0 ml/kg b.w. for 14 days. Group II cyclophosphamide (CPA): Cyclophosphamide at a dose of 10 mg/kg day by day through i.p. to rats for 14 days. Group III Fluorouracil (5-FU): 5-Fluorouracil at a dose of 10 mg/kg day by day in saline was given through i.p. to rats for 14 days. Group IV (CPA+5-FU): Rats were given CPA followed by 5-FU at a dose of 10 mg/kg per day (day by day) through i.p. to rats for 14 days. At the end of the experimental period, rats were anesthetized using light ether. Blood and testes tissue samples were taken and prepared for biochemical measurements. Biochemical parameters in rat serum and tissues were evaluated. Results: Individual injection of CPA and 5-FU to rats were reduced testes TAC, GSH concentration, GR, and CAT activities compared to control. However, the combination treatment of rats with 5-FU and CPA increased the levels of these non-enzymatic and enzymatic antioxidant compared with those treated with CPA alone. Also, results showed significantly increased TBARS and NO concentration in the testes of CPA treated rats when compared to normal ones, while 5-FU increased NO only compared with the control. Conclusion: It can be concluded that treatment of rats with CPA is associated with the production of free radicals that leads to hazardous alterations in certain non-enzymatic, and enzymatic functions. The increase in lipid peroxidation probably leads to the intracellular accumulation of ROS with the subsequent development of testes tissue injury. However, 5-FU and CPA combination could produce a significant amelioration in most cases for these changes, and it may be considered as a potentially useful candidate in the combination chemotherapy with CPA to combat oxidative stress mediated non target organs injury even if it was not a complete protection. Future work should consider combined chemotherapy regimens, as two or more mechanisms of action of chemotherapeutic drugs could be more powerful than one mechanism.Full article
