- The objectives of this study were the assessment of healthcare waste management and the characterization of healthcare waste material generated in the hospitals in Nablus city, Palestine, and furthermore, to estimate the prevalence of hepatitis B among the cleaning personnel working in these hospitals. The medical waste generation rate in kg per bed per day was between 0.59 and 0.93 kg bed— 1 day—1. The waste generation rate in the healthcare facilities of Nablus city hospitals was similar to some other developing countries; however, the percentage of medical wastes in the total waste stream was comparatively high. The density of medical waste at the four hospitals studied ranged between 144.9 and 188.4 kg m— 3 with a mean value of 166.7 kg m—3. The waste segregation and handling practices were very poor. Other alternatives for waste treatment rather than incineration such as a locally made autoclave integrated with a shredder should be evaluated and implemented. The system of healthca

- Background
A comparative food ethnobotanical study was carried out in fifteen local communities distributed in five districts in the Palestinian Authority, PA (northern West Bank), six of which were located in Nablus, two in Jenin, two in Salfit, three in Qalqilia, and two in Tulkarm. These are among the areas in the PA whose rural inhabitants primarily subsisted on agriculture and therefore still preserve the traditional knowledge on wild edible plants.
Methods
Data on the use of wild edible plants were collected for one-year period, through informed consent semi-structured interviews with 190 local informants. A semi-quantitative approach was used to document use diversity, and relative importance of each species.
Results and discussion
The study recorded 100 wild edible plant species, seventy six of which were mentioned by three informants and above and were distributed across 70 genera and 26 families. The most significant species include Majorana syriaca, Foenicul

- The effect of indigenous Trichoderma isolates against the soil-borne phytopathogen Rhizoctonia solani was investigated in dual culture and bioassay on bean plants. Ap- plication of the bioagent isolates as a conidial suspension (3*107) greatly reduced the disease index of bean plants caused by R. solani in different rates and the most effective Trichoderma harzianum isolate (Jn14) reduced the disease by 65%. In dual culture, the T. harzianum (Jn14) overgrew the pathogen R. solani in an average of 16.75 mm/day at 30 °C. In addition, the results showed that T. harzianum (Jn14) and T. hamatum (T36) were the most effective isolates at 25°C and inhibited R. solani mycelial growth by 42% and 78% respectively, due to fungitoxic metabolites production. The Effect of Trichoderma on bean seedlings growth was obvious; height was nearly doubled (160% - 200%), while fresh and dry weights increased by 133% and 217%, respectively. Ger- mination of bean seeds in treated soil with Trichoderma isolates occurred about f

- A new series of substituted 8-fluro-4H-pyrimido[2,1-b] [1,3]benzothiazole-4-ones () substituted 7-methyl-4H-isoxazolo[2,3-a]pyrimidin-4-ones, and substituted 2-methyl-5,6,7,8-tetrahydro-9H-isoxazolo[2,3-a]pyridopyrimidin-9-ones, compounds I–VII, have been prepared via condensation of β-keto esters with 2-aminopyridine derivatives, in the presence of polyphosphoric acid. The same technique has also been used to prepare diazepine compounds, VIII–X, by condensation of a γ-keto ester with 2-aminopyridine derivatives. Details of synthetic procedures are shown. The new compounds have been characterized by elemental analysis, GC–MS, FT-IR and NMR spectrometry. Antibacterial, antifungal and anticancer (cytotoxic) activities, for three of these compounds, have been investigated and are presented.

- The occurrence of entomopathogenic fungi was investigated in irrigated vegetable fields and citrus orchards soils, over a nine-month period (April-December 1999),using the Galleria bait method (GBM). Entomopathogenic fungi were found to occur in 33.6% of the soil samples studied, with positive samples yielding 70 fungal isolates, belonging to 20 species from 13 genera. Conidiobolus coronatus was the most frequent and abundant entomopathogenic species recovered, comprising 31.4% of the total number of isolates. Soil pH, soil moisture content and the geographical location had minor or no effect on the isolation of entomopathogenic fungi in the fields studied. On the other hand, organic matter content of soil, and vegetation type were found to significantly affect the occurrence of entomopathogenic fungi in soil habitats, with orchard fields yielding larger numbers of isolates than vegetable fields. Using Koch's postulates the pathogenicity of fungal isolates to Galleria larvae was found to range from 16–1
