Asthma exacerbations can be frequent and range in severity from relatively mild to
status asthmaticus. While the efficacy of intravenous MgSO4 hasbeen demonstrated, the
informations available on its inhaled role still low and conflicting, so the st
udy aim to
investigate the effect of thecombinationof MgSO4and salbutamol in the management of
acute asthma attack.
A randomized clinical trial was conducted on 76 patients, divided into two groups:
experimental (40) and control (36) patients. The trial received nebulised salbutamol with
magnesium sulphate and control nebulised salbutamol with saline serum 0.9% on three
sessions in 20 minutes. Signs of respiratory distress, wheezing, respiratory rate, pulse,
Sao2 and PEF were assessed.
Magnesium sulphate showed a significant effect in improving respiratory rate, Sao2
and PEF starting from the 20th minute( P <0.05), but did not observe the effect of MgSO4
in improving signs of respiratory distress, pulse and wheezing(P> 0,05), no side effects
attributed to magnesium sulphate were observed.Inhaled MgSO4, incombination with
salbutamol, appears to have benefits in the treatment of acute asthma attack.
Three samples of alumina_zirconia mixed oxid AL2O3_Zr2O4(1;0.25;0.1) mole ratio
based on oxides were prepared by sol-gel precipition method. The system AL2O3_Zr2O4
was obtained by mixing tow gel of alumina and zirconia precipited from aqueous solut
ions
of alumina nitrate and zirconium chlorid using ammonium hydroxide solution as precipited
agent. The system after mixing was allwed to settle for 24 h. The resuling precipitate was
filtered off and washed several times with deionized water and dried at 120°C for 24 h.
The powdered oven-dried hydrous alumina_zirconia was immersed in ammonium sulfate
solution(1) M for 24 h to incorporate sulfate ions. The resulting sample was dried at 120°
C for 24 h, calcined at 550°C for 6 h. The textural properties were determined by terating
of adsorption data of N2 at 77 K, and the results showed the changings in the textural
properties.The TG_DTA analysis showed the thermal stable of the samples in a long rang
of temperature. FTIR spectra showed that the sulfate ions were incorperated in the saples.
This study was carried out at the Agricultural Scientific Research center In Sweida -
GCSAR to study the effect of potassium sulfate and organic manure on some of soil
characteristic in addition to tree growth vigor and fruit traits of Starking del
icious apple
cultivar. The results revealed significant effect in reducing the (pH) of the soil in the three
treatments; potassium sulfate fertilization, organic manure fertilization and application of
potassium sulfate and organic manure together which were (6.608), (6.708) and (6.558),
respectively, in the comparison with the control (6.768). In addition, significant differences
were shown in the (EC) between the former treatments (0.1532 ds / m), (0.1692 ds / m) and
(0.0937 ds / m) compared to the control (0.2217 ds / m). Concerning growth vigor and fuit
traits, the results showed a significant increase in the average of shoot length in the
previous treatments (66.43, 77.33 and 71.37 cm, respectively), compared to the control
(59.37 cm), while showed a significant increase in leaf area in organic manure treatment
and potassium sulfate with organic manure together (35.54 and 37.21 cm 2, respectively),
compared to the control (30.54 cm 2). The results of analysis of variance in fruit firmness
showed higher significant variation of potassium treatment (8.477 kg / cm 2) than the
other treatments which, also revealed significant increase of total soluble solids
(16.82%,15.2% and15.37%,respectively) compared to the control (14.23%), and a
significant increase in total sugars and in percentage of treatable acidity. Consequently, the
result showed that the addition of soil fertilizers treatment contributed to improve some of
soil characters, tree growth vigor and some of the quantitative and qualitative traits of
apple fruits.
Some samples of alumina supporting with sulfate ions and molybdenium were
prepared by impregnation method. Supported samples were calcinated at 550°C for 6h.
Presence of sulfate ions and molybdenium lead to decreasing of the specific surface area o
f
alumina, and in the ease of molybdenium the decreasing value was higher. The total pore
volume was decreased with the pore size was increased. XRD patterns showed that the
incorporation of sulfate ions and molybdenium did not affect crystalin structure of
alumina. FTIR spectra showed the bonding between sulfate ionsmolybdenium
and
alumina. The TG-DTA studies showed that the losses mass was decreased when the sulfate
ions and molybdenium were incorporated, sulfate ions and molybdenium oxide
decomposed at ~700°C and ~800°C respectively .
This study aimed to determine the effect of antifungal drug (copper
Sulphate) on blood picture of broiler chickens Vaccinated with
Newcastle Disease Vaccine, We used the drug being tested by two
doses: (50, 100) ppm from the age of 7 till 45 Days.
We used /150/
chick were divided into three equal groups.
This research has included quarterly and periodically physical and chemical analysis of treatment wastewater in the Latakia countryside during year 2011 by testing three treatment plants similar in the mechanism of action and distributed in three v
illages (Happit, Al-Harah, Marg Moairban).
This study has included the measurement of temperature, pH, dissolved oxygen, turbidity, and determination of nitrate, phosphate, sulfate, and chloride.
In this research, potentiometric using Selective Electrodes ISEs, the Visible Spectrum, and the Turbidimetry methods were used.
The results showed significant differences in concentrations of the studied ions between one station to another. The highest nitrate concentrations (228.33mg/l) were recorded in Happit treatment plant especially in summer, and the highest phosphate concentrations (41.81mg/l) were in Happit treatment plant in summer. Whilst the highest sulfate concentrations which ranged between (508.67– 1157.33)mg/l were in Al-Harah treatment plant at all seasons. The highest chloride concentrations (310.33mg/l) recorded in Happit treatment plant in summer.
The statistical study has demonstrated and showed high and sometimes low correlation coefficient R2 so that gives clear indications about the sources of pollution.
A study of the effect of electrostatic charge that is generated in actuator due to drying methods on the delivered dose of metered dose inhaler has been done in tow cases:
Washing actuator and drying it by a clothe.
Washing actuator and let it dry
alone.
A study has been done on metered dose inhaler containing salbutmaol sulfate and manufactured by a local company.
The results show the importance of drying methods on the delivered dose, the delivered doses of metered dose inhaler after washing the actuator and dry it by a clothe hadn't been achieved the USP-34 requirements (out of range 75-125%), while the delivered doses after washing actuator and let it dry alone had been achieved the USP-34 requirements.
The difference in results between the two cases belong to electrostatic charge generated in actuator due to drying methods
Green chemistry requires concepts and industrial ecology using natural systems to rid industrial water flow from heavy metals, which effects badly on health and environment.
For this purpose, the changes in coefficient of distribution of mercury has
been studied in system with two phases, liquid (water contaminated with mercury) - solid (metal pyrite)
correlation of the following factors: Time of mixing phases, size of the developed steel, change the values of pH, concentration of elemental mercury, the concentration of calcium as a competitor to the occupation of sites available on the solid phase, the ratio V / M presents the water phase size on the mass of phase, which reflects the remaining time of water phase in the solid phase. The results show that pyrite can be proposed as safe environmental solution for purification of water phase of mercury, after controlling for some operation transactions.
The purpose of this study was to evaluate the success of Formocresol
pulpotomy compared with Ferric sulfate and Electro coagulation and Laser
pulpotomy in primary teeth. Fourty seven primary second molars of
children aged 5-8 years, were divided r
andomly into four groups: 10
Formocresol , 13 Ferric sulfate , 13 Electro coagulation, 10 Laser.
All teeth were filled with ZOE and sealed with Compomer, and S.S.Crown
as final restoration.
The success rate was 90 % - 84.6 % - 84.6 % - 83.3 % respectively.
These differences were not statistically significant p=0.05), but there were a
relation between the pretreatment physiologic resorption of roots and the
type of hemorrhage during the amputation procedure.
This study revealed that Ferric sulfate, and Electro coagulation, and Laser
pulpotomy are good alternative to Formocresol pulpotomy.
