إن تحديد سبب العقم، و نوعية النطاف في السائل المنوي، من أهم المحددات لاختيار طريقة العـلاج المناسبة من تقنيات الإخصاب المساعد طبياً التي أثبت اليوم بأنها الطرائق الأكثر فعالية في علاج العديـد من حالات العقم الذكري. و هي تتيح اختيار النطفة الفُضلى لإجراء تقنية الحقن المجهري للنطفـة داخـل .Intracytoplasmic sperm injection (ICSI) البيضة سيتوبلاسما في إطار دراستنا بحثنا عن احتمال ارتباط الخلل في أحد معايير السائل المنوي مع المعايير الأخـرى الأساسية، فقمنا بدراسة كل من تركيز النطاف و حركتها و شكلها. و درست 23 عينة لمرضى سوريين من الذكور الذين يعانون من قلة النطاف، و 5 عينات شاهدة تعود لأفراد غير عقيمة.
Determination of infertility cause and the quality of sperms in semen are the most important factors when we want to choose the suitable method of therapy of assisted reproduction techniques, which has been proven to be the most effective method today in the treatment of many cases of male infertility, and it allows to choose the best sperm for Intracytoplasmic sperm injection technique (ICSI). In our study we tried to find a relationship between one of the semen parameters with the other basic parameters, we studied the concentration motility and morphology of sperms of 23 infertile men with oligozoospermia, and 5 control cases for fertile men.

Textile industries are very important in Syria. Sham Countries are known with it, and the most famous
kinds of it are: Damsko and Brokar, that spread in the world. This industry is a result of many industries
starting, from spinning then fabric and
dyeing and sewing for the final product. Dyeing is an important
phase in this industry, because it offers to the product its beauty and specialty that comes with many
gestations and the changes of fashion and style, and it's an artistic and scientific industry that needs high
skills and numerous staff for work and operating.
The purpose of this research is to study noise caused by machines in three companies working in dyeing
and preparing clothes, by measuring noise levels with anchor equipment and comparing the results to
international standards in order to estimate the amount of dosages that workers in industrial
establishments face, and to come up with recommendation to reduce noise levels.
We have studied the attenuation of the surface rapid magnetic waves in the sun resulting from solar radiation and collisions and their role in heating the layers of the chromosphere and the corona of the sun, considering that this damping may be one
of the reasons for the high temperature of these two layers despite their distance from the main heat source in the sun It is the nucleus (Core).
Food Industries are among the most important and ancient industries in Syria. The most famous kinds of
it are: Yogurt and cheese industries, biscuit and juice industries.
Food industries' factories are special because of its many production lines a
nd its machines and of the
preparation needed.
The purpose of this research is to study noise resulted by machines in companies of food industries by
measuring noise levels with an anchor equipment and comparing the results with international standards
in order to estimate the amount of dosages that workers in industrial establishments face, and then to
conclude appropriate recommendations to reduce noise levels.
This study was carried out at the laboratory of artificial insemination and
embryo transfer in Ezra station Belongs to ACSAD during 2009 to estimate the
efficiency of local diluents (sodium citrate with egg yolk, EYC and skimmed
milk, SM)in compar
ison to Andromed® as a standard diluent for short and long
-term preservation period of semen in Awassi rams. Four rams, two years old
with live body weight 75± 3 Kg, were used. Semen was collected by artificial
insemination twice/ per day per week for 4 months during the breeding season.
Progressive motility and live – dead sperms were evaluated at each step of
semen handling. Results showed that there was a significant effect (p<0.05) for
the ram on ejaculate volume (1.8-2.46 ml) and sperm concentration (2.4-3.8 X
109/ml) and more significant effect (p< 0.01) for the diluents on studied traits
after each step of semen handling. The highest final survival rate of viability
(65.1%) was shown in semen diluted with Andromed® compared with 51.3% in
EYC and 22.3% in SM and the total rates of dead sperms were 41.9, 56.9.
78.9% in the standard, EYC and in SM, respectively. It was concluded that
local diluents can be used for extending and using Awassi semen as a fresh
diluted semen for a short time preservation using SM and as a frozen and
preserved semen for a long time with EYC in artificial insemination programs
and it was suggested that EYC with glycerol can be replaced for Andromed® if
sperm concentrate is increased by 10-15% at dilution.
This Study was carried-out at Shami Goat Improvement Station in Karahta.
Ten growing Shami male goats, aged 8 months, housed and managed under the
same conditions were used to study the semen characteristics. Artificial vagina
was used to collect
semen at weekly intervals, for 13 months to determine the
volume, motility, pH, and sperm concentration using Neubaure- Spectrophotometer
and Spermiodensimeter techniques.
Overall averages and standard errors of volume, motility, concentration,
and pH were 0.9 ± 0.07 ml, 65.24 ± 1.41%, 3.57 ± 0.14 billion/ml, and 6.52 ±
0.07, respectively. Seasonal variations were observed. A positive significant
correlation between volume and motility (r= 0.42, P<0.01) was found, while
negative correlations (P<0.01) between pH and other studied semen
characteristics were recorded.
Linear equations for detecting sperm concentration as measured by either,
Spermiodensimeter or Spectrophotometer were obtained.
