Levamisole, BCG, vitamin E & Selenium are traditional immunopotentiating agents. This study aimed to monitor and compare between their effects on some clinicopathological and immunological parameters. For this purpose, sixty clinically-healthy 6-months Barki male lambs were equally divided into three groups: The first group was injected S/C with l ml of levapan®10% /50kg B.Wt (100 mg of levamisole) for 3 consecutive days, while the second group was injected S/C with 0.1 ml of BCG vaccine, and the third group was injected S/C for one time with E and Se 0.5 ml /10 kg B. Wt. Blood samples were collected at 0, 3, 7, 14, 21, and 35 days. Clinicopathological and immunological parameters were estimated and statistically analyzed. The three groups displayed a significant enhancement in the estimated immunological parameters (elevated neutrophils count, neutrophils phagocytic activity and index, globulin, and acute phase proteins), but the BCG group had the highest degree of immunopotentiating action for a longer time. The E and Se group and levamisole group were almost equal. On the other hand, the erthyrogram, total antioxidant capacity, liver and kidney functions with the BCG, and levamisole groups were negatively affected, while they were enhanced in the E and Se group for 14 days. In addition, the iron profile showed significant hypoferremia, hypotransferrinemia, and hyperferritinemia with the BCG group, and non-significant changes with both, the levamisole and E and Se groups. We concluded that the BCG has a powerful and sustainable immunomodulatory effect and it is recommended to inject it combined with E and Se to avoid its side effects.

This research is aimed to know the attentions of the scientific researches of master in curriculum specialization of teaching methods of legal sciences whence its classifications of its general fields, and its subjects in every field, and scholastic stages which concerned with it, its methodology, its instrument, so as to develop and guide the direction of the scientific research for the students of higher studies. And the research has come to a group of results and the most important are: - The fields of researches according to the researches concern are regulated as following: curriculum, school books, teaching, a pupil, inspector, a teacher, education evaluation, education activities and finally curriculum. - Researchers concerning with stages of study have come as follows: intermediate, secondary, primary, education colleges and finally colleges and military institutes. And there is no research is done about colleges and technical institutes . - Researchers using curriculum research have come as follows: descriptive curriculum then an experimental curriculum. - No research used the following of the curriculum research: documentary curriculum, field curriculum, comparative cause curriculum, connection curriculum and longitudinal curriculum. - The instruments which have seen used by researchers in preparing their researches concentrated on questionnaire followed by test then the card content analysis. Whereas the researches did not use the instruments of interview and observation.

Exposure to LTE 2600 MHz microwaves is increasing very fast as new technologies and become accessible worldwide, and the smartphones being the main source of these waves. The aim of this study is to assess the thermal effect of 4G signals on rats. Forty adult Albino rats were used throughout the study, assigned as control and exposed groups, equally. Rats were kept in Plexiglas cages with intermittent exposure to LTE mobile-phone like signals at an average of 2h/day for up to 30 continuous days with SAR value of 0.982 W/kg. Infrared images were snapped immediately after the end of the exposure time, then one hour, two hours, and four hours later at a rate one collection/week during the study. IR images were analyzed by FLIR Tools software. The results exhibited variation in reflected skin temperatures in the exposed group compared to control images. Furthermore, the analysis of collected data revealed significant variations over the course of the study compared to the first week. The rise in skin temperature observed in response to exposure in the first week, which decreased gradually increased exposure and this drop in reflected skin temperature was significantly related to amount of exposure. The study concludes that the LTE 2600 MHz exposure under controlled laboratory conditions has a thermal effect on the rats.
