Phytochemical screening and Antimicrobial activity of seeds and fruits extract of Momordica balsamina Linn Mohamed, Mona Abdelmoneim; Hussien, Hanaa Taha; Mohamed, 2Sumya Abdelmoneim Resistant strains are continuously appearing in the treatment of ailments and this necessitates the synthesis of new drugs especially from naturally occurring plants. The aim of the present study was to test the antimicrobial activity and screen the Phytochemical of herbal remedies Momordica balsamina linn. This medicinal plant is a very common indigenous plant of tropical and sub-tropical regions of the world. The plant fruits and seeds were extracted using soxhlet with three solvents with different polarity starting with petroleum ether, chloroform and ethanol. Preliminary Phytochemical screening of each part extracts revealed the presence of alkaloid, glycoside, flavanoide, phenols, diterpenes, protein, and amino acids. Bioassay of antimicrobial activity of all extracts was tested against standard pathogenic microbial strains four bacterial strains and two fungi Candida albicans and Aspergillus niger. Concentration 20 mg/ml showed significant activity in all extracts tested against at least three human pathogens bacteria strains and no significant activity against the fungal strain tested. The chloroform extract shows the higher clear zone of inhibition when compared to other extracts with a diameter of zones of inhibition of 25, 21, 19, and 18 mm for Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginesa, respectively. Moderate activity against Candida albicans showed by some extracts but no activity against Aspergilles niger. The findings revealed the medicinal potential of Momordica balsamina.

A study on the status of reedbuck (Redunca redunca) in Dinder National Parka – Sudan Amolakey, Peter Amum Hussein; Mohamed, Ali Saad The Bohor reedbucks (Redunca redunca) were studied in Dinder National Park (DNP), Sudan to investigate their population dynamics and activity patterns. The road count methods was employed to investigate the population size age and sex structure , diurnal activity of a herd were studied with 10 minutes recording intervals. There were 153 individual of reedbucks in the study site of which 41% (n = 63) was confined to the EinAshamis Mayas. The sex ratio of reedbuck was 1:1. The population was female biased 51.6% (n = 79) was female excluding juveniles, and (39.2%, n = 60) as males. More adults (29.4%, n = 45) were observed more than sub-adults (9.8%, n =15) and juveniles (9.2%, n = 14). The herds were seen in aggregation of up to 45 individuals of reedbuck during the dry season in EinAshamis Mayas. The diurnal activity pattern of reedbuck group showed most animals were active feeding throughout early morning and late in afternoon, with a resting period around midday. The nocturnal activity pattern was not recorded due to the fact that no night spot equipment to scan them and no security measurement available during the night hour in the study site. The predation pressure, poaching and habitat degradation were observed as a threat to the species in the Dinder National Park. Certain management measures have been suggested.

The impact assessment of direct fence with some treatments on rangeland improvement in Semi –Arid area - - Sudan Salih, Elkheir Mugadam; Kodeal, Galal Abas Fashir; Ishaq, Yousif Musa The study was conducted at Babanousa area in West Kordofan State the aim of this study was to assess the impact of direct fence with some treatments on rangeland improvement. The rangelands were divided into four blocks A, B, C and D. the three blocks (A, B, C) were replicated in three sites, block D was taken in open rangeland in three sites used as control. Eighty quadrate samples were taken in the each sites, twenty quadrates for each block were placed in ten meter along transect during two rainy seasons. The three blocks (A, B, C) were treated by different improvement process. For vegetation measurements the quadrate method (Wilm et al, 1944) was used to study the differences in biomass productivity, vegetation cover, and plants diversity. The data obtained were analyzed to compare between the improved blocks A, B and C and the opened area (D control) using stander equations. The results showed that, the average percentages of the three fenced rangeland were higher than opened one in term of ground cover, in addition to twenty sex deferent plant species were found in the three fenced rangeland most of them were desirable plants, while eighteen deferent plant species has been found in open rangeland with more undesirable plant species. Also, the results showed differences in average plant density in the three fenced rangeland that 97 plant/meter² were found, while the average plants density in open rangeland were 62 p/m².

Ketamine hydrochloride as a General Anesthetic for Domestic Fowl Chicks: Quantal Response Elowni, Elsayed E.; Ahmed, Mohamed Fadl; Abdelnabi, Ghada H.; Badawi, Reem M. Ketamine hydrochloride was tested as a general anesthetic administered as a single intramuscular injection at doses of 1, 2, 6.7, 11.4, 20 or 22.2 mg/ bird to 2-day-old male Hisex White domestic fowl chicks weighing 30.75 g on average. In another trial, the drug was given to 6-day-old chicks of the same breed, weighing 37.7 g, at doses of 0.5, 1,2,5,8.6 or 12 mg/bird. Quantal response to treatment was expressed mathematically using probit analysis with LD50 = 3.71 mg/bird (120.7 mg/kg) for 2-day-old chicks compared with 3.75 mg/bird (99.5 mg/kg) for the older group. A dose as high as 51 mg/kg produced no mortality in 2-day-old chicks compared with a dose of 37.2 mg/kg in older birds. There is no significant difference between birds of the two age groups regarding the response to the drug as judged by the LD50 and regressive doses lower than this level. The rationale behind testing ketamine in domestic fowl chicks was discussed.
