Aim of the work: In the present study we revised the taxonomy of the mammalian species Fat Sand Rat Psammomys obesus inhabiting the Coastal Desert of Egypt by using protein separation to establishment the pervious taxonomy or not. Material and methods: The study includes electrophoresis on serum, liver, kidney and muscle proteins of three subspecies of desert rodent Fat Sand Rat Psammomys obesus. Results: The serum protein separation of subspecies terraesanctae and subspecies nicoli has the same number of proteins while in subspecies obesus has the small number of proteins. The liver protein separation of the investigated subspecies is different from each other in the number of proteins. The kidney protein separation of subspecies nicoli and subspecies obesus showed that the same number of proteins while subspecies terraesanctae has the smallest number of proteins. In the muscle of femur bone, the protein separation in subspecies nicoli, terraesanctae and obesus had the same number of proteins. As a result of the high similarity between subspecies obesus and terraescantae, must be collected in one subspecies called obesus and the third subspecies still as it nicoli.

Cabbage, one of the favorite food in Egypt and many other parts of the world, has been reported for its potent action as antioxidant as well as its content of anticancer compounds. The main objective of this work is to test the antioxidant activity of cabbage seed extract against the effect of gamma rays on the structure of cauda epididymis and epididymal sperm morphology in rat. Silymarin, a plant extract, is a potent antioxidant was used in this study as a comparing reference for the extent of Brassica extract activity. Ninty male albino rats were used and divided into six groups: Group 1 (control), group 2 (irradiated control), group 3 (cabbage seed extract), group 4 (cabbage irradiated), group 5 (silymarin extract) and group 6 (silymarin irradiated). The experimental rats were scarificed at 1, 7 and 21 days post- 6 Gy whole body irradiation. Specimens of the cauda epididymidis dissected, smears of semen were collected from them, placed on slides and stained by H and E for studying of spermatozoa. Paraffin sections of cauda epididymidis were prepared and stained by H and E for histological study. Irradiation caused a highly significant decrease in the tubular diameter of the cauda epididymis.Itinduced degenerative changes in the form of decreased thickness in the lining epithelium of the tubules,congestion of blood vessels, tubular collapse and reduction of luminal spermatozoa with increased abnormal forms as compared to the control. In Brassica drenched rats and after irradiation, there was non significant decrease in the diameter of epididymal tubules as compared with the corresponding control. There was a marked improvement in the height of the lining epithelial cells that appeared more or less similar to the control. In most specimens of the epididymidis from silymarin drenched and after one day of irradiation, the tubular epithelium was thin and the lumen was small, irregularly shaped with sticky luminal spermatozoa. However, after three weeks of radiation, sections of the epididymidis showed ameliorative effect of silymarin. In conclusion, Brassica seed extract proved to be radioprotective as much or even better than silymarin against radiation effect on epididymis as well as sperms.

The Study area in wadi Hasanat, Salah District, Taiz is located between latitude 14° 989' 26'' and 14° 994' 18'' north and longitude 43° 395' 463'' and 43° 395' 702'' east. Regular periodic field visits (three visits/month) were carried out during the years 2007-2008 to study and collect plant samples for the different taxa and to collect soil samples from the different habitats of the wadi. All the collected plant samples were correctly identified and classified. This study aimed to enumerate and identify the plants in the study area which reached 165 species belonging to 49 families. Out of them are four species of Pteridophyta distributed in three families. Gymnospermeae are represented by three genera, and 46 families. The Angiospermeae were represented by 128 species for 98 genera within 40 families of the Dicotyledoneae, and 33 species from 25 genera within six families of the Monocotyledoneae.. The study showed that the largest five families in the wadi Hasanat are Poaceae "Gramineae" (26 species), Asteraceae "Compositae" (16 species), Acanthaceae (13 species), Euphorbiaceae (11 species) and Asclepiadaceae (9 species). Out of 165 plant species identified in this study, 29species disappeared as a result of road paving at the bottom of the wadi the and exposure of the wadi to over grazing and wrongful woodcutting seriously threatened the wadi. The wadi is considered a beautiful green patch, and wonderful view for Taiz City, and an important center for air purification from the pollutants coming out of Taiz city located on its north. Therefore , it is necessary to preserve the wadi disturbance by a planned way especially with the shrinkage of the green areas surrounding Taiz City day after day.
