Our study included (84) patients: 86 cases suffering from chronic osteomyelitis: various causes, location and degrees.
All patients operated: after curettage of necrotic and infected tissues; system of continuous irrigation with antibiotics was in
serted to the infected zone; all cases were followed up for 1 year. 86% of positive results were obtained and results were bad in 14% of cases>
The high positive results (86%) confirm high effect of continuous irrigation with antibiotics as a good method for chronic osteomyelitis treatment, because this method allows delivery of suitable antibiotics in high concentration into the infected area, which is enough to kill microbes and allows to obtain best results.
The study was conducted in 2011 on 6-years-old citrus trees "Washington navel
141". It contained four treatments with three replicates for each treatment. The results
showed that:
The wastewater treatments showed superiority on the control in the
number of
vegetative growth and its length.
The number of inflorescence buds, was increased in the second treatment (irrigation
with 50% treated wastewater +50% normal water) (5. 37) which dominated the other
treatments.
The weight of fruit was affected by treated wastewater irrigation. Second treatment
(irrigation with 50%treated wastewater+50 % normal water) was better than the control
treatment. It was increased by (308. 3 g) compared to (259. 5 g) for the control treatment.
Fruit yield production per tree, was increased by second treatment (irrigation with
50% treated wastewater+50 % normal water) (28. 9kg) compared to (15. 3kg) for the
control.
Treated wastewater irrigation had positive effects in the quality of fruit
(Total sugar %), (T. S. S %) and the coefficient of maturity were increased in second and
third treatment compared to other treatments, while (T. A %) was decreased in all
wastewater treatments.
To compare total and subtotal gastrectomy performed by
laparoscopic technique with those performed by open surgery, and to
determine whether laparoscopic surgery has an important role and
advantages in gastric resection.
after the use of systemic chemotherapy pre- and post surgery
the management of malignant bone tumors have been changed and the rate
of survival has improved up to more than 65%, and in some studies more
than 75%.
The Limb Salvage Surgery is now t
he standard treatment of malignant bone
tumors, especially in the lower limb
In the last three decades, the use of prosthesis has sharply risen in the world
in order to have good functional results and better life
Aims: introducing the serious complications of tumor prosthesis by
analysing of 342 cases followed for 10 years.
In the present work, batch electrocoagulation experiments were carried out
to evaluate the removal of polycyclic aromatic hydrocarbon (PAHs) from water
using aluminum electrodes. The effects of initial pH, current density,
electrolysis time, initi
al concentration of PAHs, electrolyte type, and electrolyte
concentration were investigated to achieve the optimal removal efficiency. The
results indicated that the electrocoagulation utilizing the aluminum, as anode
and cathode, was an efficient tool in the reduction of these contaminants. The
treatment process was found to be largely affected by the current density and
the initial composition of water. The removal rate was significantly increased
using NaCl as an electrolyte where indirect oxidation by hypochlorite forming
later during the treatment was occurred. The results demonstrated that the
technical feasibility of the electrocoagulation as a possible and reliable
technique for the treatment of PAHs contaminants in water.
We reviewed sixty patients, who had metastatic fractures, they were
treated in Al Moassat Hospital during the years: 1994-1995-1996. The
location of fractures were:
51 in upper third of the femur
3 in proximal humerus
2 in scapula
2 in tibia
2
in different positions
We studied the methods of treatment, complications and postoperative
survival.
Fluoride ion is present in high concentration in some regions in Syria. As
fluoride occurs naturally in water, We have studied some methods of fluoride
removal such as Nalgonda technique and activated carbon method.
In Nalgonda technique we add Al
um and lime to the water, and we have
found that fluoride removal efficiency remains constant when the initial
concentrations of fluoride changes, or when the chloride ions exists in water,
but it depends on pH, and get better when the method is investigated in two
steps. In addition, adsorption of fluoride decreases with increasing
sedimentation time, or using Ventilated lime or CaCO3 instead of Ca (OH)2.
In activated carbon method we have done different experiments by using
charcoal of coconut coir, date seeds and olive seeds. And we have found that
olive seeds carbon is better than others, and its fluoride removal efficiency
increases after impregnation with solution of 2% Al2(SO4)3.
In this study, microorganism separated from the Syrian soil were used in
treating the waste water from dyehouse and some dyes which are oftenly
applied. A great difference was found in the speed of microorganism growth as
well as the great variati
on in color disappearance, in addition to inactivating
the enzymatic work by some of the dyes. Also, the effect of the dyes density on
the growth of microorganism. The absorption strength measurment in the field
of visible spectrum between ٣٥٠ –٧٥٠ nanometers was adopted for analyzing
the filtrates resulting from the biological treatment .
تعد أزمة الطاقة و التدهور البیئي من أهم المشاكل التي تواجه البشریة في عصرنا الحالي، و یعود السبب
إلى تزاید عدد السكان و تسارع التطور الصناعي التي ینتج عنه كمیات ضخمة من النفایات الصلبة،
فقد أصبح من الضروري الاستفادة من هذه النفایات باستخدام تقانات
ملائمة من أجل التخفیف جزئيا من التدهور البیئي الحاصل و النقص الموجود في مصادر الطاقة.
