ABSTRACT
The response of seven species of Silene to temperature, salt stress and pH was evaluated. The germination of seeds exhibited considerable variability in germination percentage and germination rate index in response to constant and alternating temperatures [20 to 30°C], salt concentrations [0 to 10.000 ppm] and pH [6 to 8]. The optimum germination temperature was the alternating 20/30°C. The maximum temperature for germination was between 30 and 35°C and the minimum was between 15 and 20°C. The seedlings of S. rubella and S. behen were more tolerant to salt concentration [up to 250 ppm] than the other five species. The optimum pH for seed germination were at pH 8 with decrease in germination at values below pH 6. The radicle length was maximum at an alternating 20/30°C for S. conoidea and the hypocotyl length was maximum at 30°C for S. apetala var. grandiflora. With increased salt concentration [from 0 to 10,000 ppm] the radicle and hypocotyl were reduced in length. Shorter radicles at pH 8 were found with S. nocturna and S. villosa but shorter hypocotyl at pH 4 was S. apetala var. grandiflora

The aim of this study is to explore psychological and social responses and personality dynamics of chronic renal failure patients when they are informed of the nature of their disease and of what is likely to happen to them in their future life. Thirty-five patients with chronic renal failure on regular haemodialysis, who are treated in Assiut University Hospital were investigated. Their ages ranged from 25 to 63 years [means + S.D. = 39.51 years + 9.96]. Thirty controls were also studied their ages ranged from 20 to 60 years [mean + S.D. = 41.56 years + 12.22]. All patients to assess their psychological state after suffering from chronic renal failure. Three types of tools have been used: 1. Psychometric tools. 2. Clinical tools. 3. Analysis of Dreams

Prurigo of Hebra is a chronic pruritic papular skin disease of unknown etiology. The disease affects mainly children and rarely extends into adulthood. The disease is now rarely diagnosed. Very few facts are known about such a condition. Clinical studies and histopathological examination of biopsies from skin lesions and associated lymph node enlargement besides immunological studies for the serum level of immunoglobulins were done for 25 cases. Findings point to the condition of being a possible unusual manifestation of atopy as evidenced by a significant rise of IgE serum level than in control subjects
