Evaluating the Reliability of Different Radiodensitometric Softwares by Calibration with Cone-Beam Computed Tomography Waleed Suleiman

Abstract:
Background and aim of the study: Nowadays, radiographic bone density measurement softwares became a commonly used techniques in the daily practice. This study aims to evaluate the reliability of four different softwares compared with Cone-beam CT values.
Materials and Methods: A 100 different cross-sectional projections were obtained from 25 patient’s CBCT files. Regions of interests ROIs were alveolar process in the posterior maxillae. Bone densities were measured in the original sections using the CBCT software, the same sections then loaded to obtain the radiographic bone densities from the studied softwares. Pearson’s correlations coefficients “r” were studied between the previous variables and Alpha Cronbach’s test used to evaluate the reliability of these softwares.
Results: The correlations between densities derived from cone-beam CT and density values derived from Digora 1.51 and 2.5 were strong (r=0.697, P=0.000) and (r=0.602, P=0.002) respectively, whereas the maximum “r” value obtained when correlating CBCT values with Idrisi Kilimanjaro software values (r=0.855, P=0.001). The correlation was moderate with other softwares. Alpha Cronbach’s test showed low reliability of these softwares.
Conclusion: Idrisi Kilimanjaro software showed the most validity for radiodensitometric determination. The version 1.51 of Digora seems to be better than version 2.5, whereas Scion Image and Image J showed moderate validity. All studied softwares have low reliability when calibrated with cone-beam CT.

Pharmacognostic study of Melissa Dr. Emmad Al-Haddad

Abstract:
In October 2014 the collected air-green samples of melissa
officinalis were gathered. Then the volatile oil from fresh samples
was extracted with N-hexane and other samples with steam
distillation.
Suitable conditions were chosen to separate the components of the
volatile oil by GC-MAS and we noticed :
(25) compounds were found in the extracted volatile oil of the first
sample ( extraction by N-hexane ).
3 compounds of them are alcohol noncyclic MonoTerpine class and
they form 3,46% of the volatile oil weight, 1 alcohol cyclic
Monoterpine compound forms 1,83% of the volatile oil total
weight, 1 compound from cyclic DeTerpine class and it forms
2.31%, 2 compounds from cyclic MonoTerpine class and they form
3,14%, 2 compounds from Aldyhol group which form 52.03% from
the volatile oil’s weight.
13 compounds from SesquieTerpine class with a 35,14% of the
total weight, 2 Ester compounds and they form 2,12%, and 1 acetic
compound which is Lenolenic acid with a 0,97% form the volatile
oil total weight.
Also volatile oil of the second sample ( extraction by steam
distillation) contain (21) compounds.
5 compounds are from alcohol noncyclic Monoterpine class and
they form 23,34% from the volatile oil weight.
4 compounds are alcohol cyclic Monoterpine and they are 10,13%,
1 cylcic MonoTerpine compound and is 2,17% from the total
weight, 2 compounds from Aldyhol group and they form 25,85%, 8
compounds from SesquieTerpine and they forms 35,31%.
And 1 compound from Keton group which forms 2,9% from the
volatile oil weight.

Study of extraction of active ingredients of Fennel Herb medicineDr.Emmad AL- Hadad

Abstract:
In September, 2014, the collected air-green samples of Fennel herb
were gathered. Then the volatile oil from fresh samples was
extracted with N-hexane and other samples with steam distilled
water.
Suitable conditions were chosen to separate the components of the
volatile oil by GC-MS and we noticed :
(10) compounds were found in the extracted volatile oil of the first
sample ( extraction by N-hexane ).(6) compounds of them are from
MonoTerpin class , and they form 22.5%. (four of them are cycle
Terpin and they form 19.86%) (tow of them are open Terpin and
their form 2.64%) of the volatile oil weight .
Phenol-ethers form 73.36% of the volatile oil weight. Anethol is the
main compound of the oil total weight. and Acetate form 4.55%.
Also volatile oil of the second sample ( extraction by steam
distilled water) contain fourteen compound. Four compounds are
cycle MonoTerpintine and their form 13.99% from the oil total
weight and three compounds from Phenol-ethers and their form
74.4% from the oil total weight (Anethol is the main compound of
the oil total weight and it form 64.06% ).
Also we found on compound from sesqy Terpin it form 1.07% from
the oil total weight.
And we found three esters compounds and their form 6.36% from
the oil total weight and we found diterpen compound ( phytol) it
form 2.13% from the oil total weight.
Also we found one alcohol compound and Linolenic acid.

The study of essential oil’s ingredients of Ocimum Basilicum (Basil) herb leaves and its anti-bacterial effects.Dr.Emmad AL-Hadad

ABSTRACT 
In October 2014, the collected air-green samples of Basil herb were gathered from the region of MashtaAlhulu. Then the volatile oil from fresh samples was extracted with N-Hexane and other samples with steam distilled water, and we have found that the percentage of the volatile oil in the first sample (N-Hexane) is 2,7% , and 2,5% in the second sample (steam distilled water). Suitable conditions were chosen to separate the components of the volatile oil by GC-MS and we noticed: – the first sample (extracted with N-hexane) contains 18 compounds, and they are: Six Terpenes compounds and they form 21.22%, Hydrocarbon compounds form 21.8% from the total weight and they are 7 compounds, and one compound from Ketone class dicycle and its percentage is 2.32%, and two Ester compound and they form 18.96%, One phenolic compound and forms 21.60%, one Ether compound and forms 14.08%. -the volatile oil from the second sample (extracted with steam distilled water) contains 11 compounds, and they are: 6 compounds belong to Hydrocarbon class and they are the main components in the volatile oil with a 91.24% of the oil total weight, One compoundfrom Ether class forms 1.62%, one phenolic compound which forms 3.93%, and three Terpenes compounds and they form 3.17%.
