هدف البحث هو تقييم دور الكرب التأكسدي معبراً عنه بقياس مستويات مالون ألدهيد malondialdehyde (MDA) لاختبار أكسدة الشحوم كمشعر للكرب التأكسدي في عينات المصل في الأذيات السميّة الناتجة عن التعرض للمبيدات الحشرية المثبطة للكولينستيراز (الفوسفورية العضوية و الكارباماتية) عند العاملين في البيوت البلاستيكية في المنطقة الساحلية في سوريا. تألفت عينة الدراسة من مجموعتين غالبيتهم من الذكور: مجموعة العاملين في البيوت البلاستيكية الذين يقومون بتحضير و رذ المبيدات الزراعية (عددهم 100، العمر 18-61 سنة ) و مجموعة شاهدة من أشخاص لم يتعاملوا مع المبيدات أبداً (عددهم 50، العمر19-58 سنة). تم قياس مستويات مالون ألدهيد باستخدام المقايسة المناعية الممتزة المرتبطة بالأنزيم (ELISA). و كانت النتيجة مستويات MDA في مجموعة العاملين المتعرضين أعلى بفارق معنوي هام مقارنة مع المجموعة الشاهدة (P< 0.05)، و بالتالي يمكن اعتبار MDA مشعراً حيوياً للكرب الناجم عن الأكسدة عند تعرض العاملين في البيوت البلاستيكية للمبيدات الحشرية المضادة للكولينستيراز. و قد تكون وسلية مساعدة في تشخيص و مراقبة التعرض لدى هؤلاء العمال بالإضافة إلى أنزيم الكولينستيراز.
The aim of this study is to examine the role of oxidative stress (OS) by measuring Malondialdehye (MDA) levels to test Lipid Peroxidation as a marker of oxidative stress in serum samples in toxic injuries resulting from exposure to anticholinesterase insecticides (organophosphates and carbamates) in greenhouse workers in the coastal region of Syria. The study population comprised two groups (the majority of males): greenhouse workers who prepare and spray pesticides (100 workers, aged 18-61) and Control group (not never handle pesticides, 50 subjects, aged 19-58). Malondialdehye (MDA) levels were measured using enzyme-linked immunosorbent assay (ELISA). There was a significant difference in MDA levels in greenhouse workers group compared to control group (P˂0.05). Therefore, MDA levels could be considered as a biomarker for oxidative stress in greenhouse workers exposed to anticholinesterase insecticides and might be a useful diagnostic aid and monitoring exposure in those workers as well as cholinesterase enzyme.

This research was carried out in four different regions on the Syrian coast on four herds of Shami goats different in numbers. These were grown in different ways depending on farmers' concepts and needs, and the geographic location of each region. T
he number of goats that were studied was (44). The daily average of milk production per goat was calculated, in addition to the monthly average and overall average for every herd during the lactation season which was divided into two phases (Breastfeeding, Lactation) .In the first phase it was (2493,9 – 2238,6 – 1776,6 – 81,6) L ordered by herd and method of breeding (4 – 2 – 3 – 1) and same was in the second phase. The average production rate was (54,27)% in first method of first herd and in other methods was lower than (50)% and increased in other herds (49,39 – 45,36 – 44,16)% respectively (2 –4 – 3 – 1). It was noticed that in the second phase of Lactation the herd of first method retracted to lower than (50)%and rose in other herds (55,83 – 54,63 – 50,60 – 45,72 )% Respectively (1 –2 – 4 – 3). Statistical analysis demonstrated the lack of significant differences in second and forth herd in spite of the different methods used in the other herds, and in second phase statistical analysis was in four herds in accordance with different methods of breeding.

This study was conducted to investigate the incidence of
infectious bronchitis virus (IBV) QX type in commercial broiler
flocks in the Middle and Coastal Region of Syria.
An assessment of nine vicia faba genotypes (flip84-59fb, AGUADOLCE LB 1266
SML, FLIP84-14FB, GIZE.461, REINA BLANCA, autochthon, Spanish, and Cypriotes)
was achieved, during 2010-2011 and 2011-2012 seasons, in Al_Bassa farm, near Lattakia
city. Su
perior genotypes will be adopted as a high yield improved varieties in that area,
however, the other genotypes (possessing genetic characteristics, superior of local
genotypes), will be used in future breeding programs.
The results indicated a significant differences between studied characteristics of the
genotypes, as Spanish genotype recorded the best pod length (17.16cm), having high
degree of inheritance (68.24), followed by filp84-59fb genotype (15.1 cm), with weight
seeds per pod (33.6 g), having high degree of inheritance (68.45), followed by the Cypriot
genotype, by seed weight (14.66 g), number of pod (4.6), having low degree of inheritance
(23.53), followed by Cyprian autochtone genotype, and Aguadolce.lb1266,and filip84 -
14fb number of pod (3.6).
The Cypriot genotype was the best, in terms of pod weight (23:43 g), having high
degree of inheritance (76.45) followed by Spanish (20.63g), and seed weight (3.93g),
having medium degree of inheritance (54.82), followed by style filip84-59fb (3.73 g), and
100-seed weight (4.1g), having high degree of inheritance (97.49), followed by Aguadolce
genotypes (285 g).
The SML genotype is the best among premature genotypes in terms of flowering (46 days)
and maturity (148 days), followed by Cypriot in terms of flowering (51 days) and flip84-
59fb in terms of maturity (155 days)
Soil water erosion is one of the most important factors of soil
degradation. Soil erosion is a process that causes loss of big
amounts of nutrients and organic matter from the topsoil layer and
pollutes the surface water bodies. The USDA- WEPP (Wa
ter
Erosion Prediction Project erosion model) represents a new
generation technology for estimating soil loss by water erosion and
sediment delivery from hillslopes and small watersheds. The main
purpose of this study was evaluating the capability of WEPP model.
In this study, trends of annual and seasonal precipitation time series for the period of (1971–2006) were analysed for three meteorological stations (Lattakia, Tartous and Safita) located in the coastal region of Syria, by linear regression and Spear
man's rho tests.
The results showed a decreasing trend of annual precipitation in Lattakia and Tartous stations and increasing trend in Safita station. At the seasonal time scale, a decreasing trends of winter precipitation in Lattakia station and of spring precipitation in all stations were observed. While an increasing trends of winter precipitation in Tartous and Safita stations and of autumn precipitation in all stations were observed. Although, all of these negative and positive linear trends, both at the annual and seasonal time scales are not statistically significant at 5% level, but they can have severe effects on water resources, rivers regimes and success of rain-fed crops in the study areas
