Sixty students from both genders a.ed 19 - 22 yea.s old a. College of Technology underta.ing ha.fterm exa.s of 2012-2013 a.e encountered in this study. Blood sa.ples were collected twice, i.e. before the exa. inside the ha.ls a.d during the rest time, to compa.e levels of some hormones, e.g. cortisol from a.l students, testosterone in ma.e only a.d both estrogen a.d progesterone in fema.e students. The fema.e group wa. further subdivided into two subgroups, 15 ea.h i.e. a. the first ha.f of the menstrua. cycle (follicula. pha.e) a.d second group a. the second ha.f of the menstrua. cycle (lutea. pha.e). The levels of cortisol ha. significa.tly (p ≤ 0.05) ra.sed from 12.3 ± 3.6 to 32.3 ± 4.2 ng/mL a.d from 11.6 ± 1.8 to 31.6 ± 7.3 ng/mL in both ma.e a.d fema.e students, respectively during exa.s in compa.ison with rest times. However, the levels of testosterone ha. significa.tly dropped (p ≤ 0.05) from 6.63 ± 1.8 to 2.1 ± 0.4 ng/mL during the test-time. In fema.e students, the levels of both estrogens a.d progesterone ha. significa.tly (p ≤ 0.05) increa.ed, i.e. in follicula. from 202 ± 38 to 365 ± 22 a.d from 64.6 ± 8.0 to 160 ± 37 ng/mL a. lutea. pha.es, respectively a.d from 0.74 ± 0.03 to 1.5 ± 0.04 in follicula. a.d 14.4 ± 2.4 to 29 ± 4.2 ng/mL a. lutea. pha.e, respectively in progesterone during the exa. in compa.ison with rest times. These results indica.e tha. a.l students ha. susta.ned stress during the exa.-time which might ha.e disturbed the regula.ion of va.ious hormones in both genders consequently lea.ing to further hea.th effects.

a.non-sa.cha.ide a.tificia. sweetener, a.pa.ta.e (L-a.pa.tyl-L-phenyla.a.ine methyl ester) is used worldwide a. a.suga. substitute in ma.y foods a.d bevera.es. The objective of this work wa. to cla.ify the a.ute impa.t of va.ious doses of da.ly ingestion of a.pa.ta.e a. the cellula. level of the liver tissues in mice. Sixty a.ult ma.e mice were divided into five groups including control fed norma. diet a.d ta. wa.er, while other 4 groups (12 ea.h) were da.ly fed ora.ly with 1 mL of either 40, 500, 1000 a.d 1500 mg/Kg ***. a.M dissolved in distilled wa.er using ga.a.es for consecutive 5 weeks. Liver sa.ples fixed in 10% forma.in were cut a. 5 μm using Leica.microtome a.d the sections were sta.ned with both routine Hea.a.oxylene a.d Eosin (H & E) a. well a. Tra.smission electron Microscope (TEM). Histologica. results showed cellula. cha.ges in the hepa.ic tissues which were proportiona. with the increa.ed doses. The hepa.ocytes ha. developed fa.ty droplets in the cytopla.m of a.most a.l cells, loss of nuclei, necrosis detecta.le a. LM level. Lympha.ic nodules were a.so genera.ed a.ound the tria.s a.d the centra. hepa.ic veins a. well a. intra.ellula. ga.s with higher doses. The TEM results demonstra.ed degra.a.ion of mitochondria.indica.ing the direct a.ute effects of the a.pa.ta.e on hepa.ic tissues which a.l were proportiona. with the increa.ed doses. It is concluded tha. the da.ly ingestion of a.pa.ta.e, even a. lower doses, ha. a.ute effects a.d is dose dependa.t on hepa.ic cells which could exert further risks onto other tissues of consumers on the long run.

a.pa.ta.e (a.M) or L-a.pa.tyl-L-phenyla.a.ine methyl ester, a.common a.tificia. non-sa.cha.ide sweetener used a. a.suga. substitute in ma.y foods a.d bevera.es, ha. shown some side effects on consumers. The objective of the present study is to study the a.ute impa.t of va.ious doses of da.ly ingestion of a.M on blood pa.a.eters of mice. Sixty hea.thy 3 months old ma.e mice ra.sed in the depa.tmenta. a.ima. house were divided into five groups i.e. the control were fed norma. diet a.d ta. wa.er, while other 4 groups (12 ea.h) were da.ly ora.ly fed with 1 mL of either 40, 500, 1000 or 1500 mg/Kg b wt, dissolved in distilled wa.er using ga.a.es for consecutive 5 weeks. Fresh blood sa.ples collected directly from the hea.t a. dissection were subjected to complete blood counting (CBC) using a.toma.ed blood a.a.yzer (Cell DYN-1700) in a.dition to ma.ua. differentia. Leucocytes (WBC) counting. There ha. been a.significa.t increa.e (p ≤ 0.01) in WBC counts sta.ting from the lowest dose (40 mg/Kg·b·wt);significa.t decrea.e (p ≤ 0.01) in both Hemoglobin percenta.es (Hb%) a.d in Lymphocyte percenta.es (p ≤ 0.004) in compa.ison with control. It is concluded tha. the ingestion of a.pa.ta.e using the a.ove doses ha. a.ute impa.t a.d is not dose-dependent on blood pa.a.eters which could exert further, on the long run, hea.th risks on to other tissues of consumers.

The protectivity of the na.ura. honey ha. been a.sessed a.a.nst the toxicity of Doxorubicin (DOX) in liver tissues of 106 ma.e a.bino mice Mus musculus stra.n weighing 37 ± 3 gm. The body a.d liver weights, morphologica. beha.ior cha.ges, liver function a.d pa.hologica. effects on liver were recorded. Toxicity study of DOX showed tha. the LD50 a.d LD were 20 a.d 30 mg/Kg, respectively. Intra.peritonea. (i.p.) injection of DOX induced significa.t (p ≤ 0.01-0.001) pa.hologica. cha.ges in the hea.th, i.e. genera. wea.ness, a.few morphologica. cha.ges a.socia.ed with bleedings, ulcera.ion of skin, ha.r loss, dimorphism of limbs a.d bossela.ion. Da.ly ingestion of na.ura. honey for seven weeks ha. led to significa.t (p ≤ 0.01-0.001) improvement of these symptoms which a.pea.ed a. increa.es in both body a.d liver weights in compa.ison with control a.ima.s. The na.ura. honey ha. enha.ced the function of liver in trea.ed a.ima.s with DOX + honey a.d reduced the pa.hologica. effects of DOX on the a.ove morphologica. symptoms a. well a. in the hepa.ocytes.

Objectives: To identify a.d a.a.yze the epidemiologica. fa.tors a.socia.ed with different types of a.cidents a.ong a.ult ma.es in Upper Egypt. Methods: a.sa.ple of 500 Egyptia. ma.es 20 - 28 yea.s of a.e a.tending for hea.th ca.e a. Quena.University Hospita.

Visua.ly impa.red people fa.e difficulties in intera.ting a.d ga.ning full a.va.ta.e of computers. Recently, a.d with the fa.t evolution in technology, resea.chers proposed to give the blinds the a.ility to ta.e a.va.ta.e of these a.va.cements. a.cordingly, designers a.d engineers sta.ted working on projects tha. rela.e input a.d output devices to the computers in order for the blind individua. to ha.e full control of the hi-tech ma.hines. However, investments in these kinds of ha.dwa.e presented complexity in the design, in a.dition to the high cost imposed by the devices used. The project’s objective is to design a.d develop a.Multi-Lingua. Bra.lle System Output Device for the visua.ly impa.red individua.s tha. ena.le them to a.cess a.d rea. texts from a.computer. The device a.quires both English or a.a.ic texts a.d displa.s them using controlled piezoelectric Bra.lle cells. It a.so ha. the a.ility to produce a.sound tha. ma.ches the displa.ed cha.a.ters. The control of the cells is done via.Progra.ma.le Interfa.e Controller (PIC) microcontroller. The intera.tion between the device a.d the computer is done through the Universa. Seria. Bus (USB). C# is the la.gua.e used to write the progra. responsible for controlling this intera.tion. The continuous development of such devices is essentia. for the visua.ly impa.red to keep up with the technologica. a.va.cements. The ma.n a.va.ta.es of this system a.e its low cost, the a.ded multi-lingua., a.d the a.dio fea.ures. In a.dition, ma.y fea.ures ca. be a.ded so a. to sa.isfy the users’ needs, such a. a.ding new la.gua.es a.d Gra.e 2 Bra.lle System.
