Smoking tobacco is probably the single most significant source of
toxic chemical exposure to humans, and that affects many human
organs .smoking is a major risk factor for various types of
cancers.The specimenen compassed of two groups of voluntee
rs:
the group included 20 volunteers of smokers, the second
group included14 volunteers of non-smokers as a control group.
Surgical biopsy from oral buccal mucosa were taken and stained
with ( P21,p27 clone) antibody by IHC, and we count the positive
stained cells in two study groups to show if the gene p21,p27 is
affected by cigarette smoking, and investigate the possibility of a
mutation in it .statistical clear differences between the two groups .
the control group is negative while the two groups was positive.
Purpose: to study the Distribution of intraocular pressure in the age group 20-40 years old and the related factors: age, gender, family history, BMI, smoking.
Methods: This was a population-based cross-sectional study of 1000 subjects All particip
ant underwent IOP (intraocular pressure) measurement and a standardized survey for the initial data of the study.
Results: The mean IOP for the study subjects was (17.6mmHg); the mean IOP in men was higher than women (17.53) vs (16.8) mmHg respectively. Ocular hypertension was found in 16.8% participants. IOP increased 0.5 mmHg for every 10 years of age. BMI (Body Mass Index) had a positive association with IOP. Subjects with positive family history of ocular hypertension had higher IOP (18.46) vs (16.98) mmHg. IOP was higher in smokers’ group (17.77) vs (16.29) mmHg. Multivariate analyzing showed that aging, smoking, male sex, family history were independent risk factors for ocular hypertension, otherwise there was no significant relationship between ocular hypertension and BMI.
This study aimstoinvistigatethepopularity of smoking habit among high school
students who were taken as a study sample. It also, determing the social factors and family
circvmistancy that cavseteenagrs to smoking, for that purpose we used the descr
iptive
analytical approach ,and the questionnaire was adopted (designed) as a tool to collect
information, and it was distributed on a sample of (100) student in a secondary school in
al-qutaifa city in damascus countryside. Resultsshow that the impact of social and family
factors on the tendency of secondary school students to smoke: to express their manhood,
to feel confidence, and non application the decision which prevent children and
adolescents from purchasing cigarettes.
The family factors inclvde : the imitation of the children to their parents and relatives
who smoke, more coquetry from parents to their children , in addition to that there are
satellite channels and website which affect the children and adolescents . Finally, it was
ended up to several recommendations
Khat chewing is a deep-rooted habit in Yemen. It has many
negative impacts on different body systems. The spread of khat chewing
among adult males in Yemeni society needs special attention. Cathinone
and cathine are the most stimulants of khat ing
redients. Other ingredients
could have other implication such as gastrointestinal carcinogenic tannins.
the aim of this study is to Investigate chronic khatchewing
effects on oral mucosa and the role of concurrent smoking.

Because of the special importance of saliva in the field of dentistry, we have
discussed the relation between the dry mouth and the reduction of salivary flow
rate.
We have indicated in this study the adverse effects of smoking on the salivary
gl
ands and the relation between smoking and the dry mouth, on one hand, and
salivery flow rate on the ather.
We have also referred to some cases in which the indivedual feels the dryness of
the mouth in spite of the possibility of measuring salivary flow rate easily.
In this research, the concentration of thiocyanate ion in serum has been investigated,
thiocyanate has negative effects on human body when it increasses higher than specific
limit, this ion is produced by the metabolism of cyanide which exist in ci
garette smoke.
Spectrophotometric method has been used in the visible range at λ=460 nm, the formation
of the complex between thiocyanate and reagent Ferric chloride (FeCl3) have been made in
an ideal parameters such as temperature 25 ºC, time=15 min, pH=4.4, volume of citrate
buffer=0.75 ml, volume of reagent (FeCl3) =1 ml and concentration of reagent = 0.02
mg/ml.
The selected method showed good accuracy and precision, the accuracy of the method has
been validated with R=99.3%, and the precision of relative standard deviation was
(RSD<=1.149 % .
The concentration of thiocyanate has been studied in a sample of 240 non-smokers’ and in
a sample of 240 smokers’, these samples have been divided into different age groups.
The maximum concentration of thiocyanate was 89.49 μmol/L in the fourth group (>50
years) of the non-smokers’, and the maximum concentration of thiocyanate was 190.27
μmol/L in the fourth group (>50 years) of the smokers’. The maximum concentration of
thiocyanate was 91.647 μmol/L in the non-smokers’ males and 86.623 μmol/L for the nonsmokers’
females, whereas the concentration of thiocyanate was 204.53 μmol/L in the
male smokers’ and 167.33 μmol/L in the female smokers’.
Background: smoking is the major cause of many chronic diseases and a growing
public health problem in the world. - Aim: the aim of this study is to determine
prevalence of smoking habit and associated factors among students of Al-Andalus
universi
ty of medical science. - Methods: A cross sectional study was conducted from
October academic year 2017 to March academic year 2018 on 300 students in Al- andalus
Medical University. A systematic stratified sampling method was used. Data collected by
self-administrated questionnaire. - Results: out of the 300 respondents, 166 students were
smokers giving a prevalence rate of 55%.The prevalence of smokers were much higher in
males than females (79.5% and 20.5%, respectively). 72.2% of students started smoking at
the age of less than 20 years. There were a significance differences between faculties (P=
0.02) , which faculty of medicine reported high percentage. - Conclusions: This study
directs the attention to the fact that problem of smoking among university students has
important contributing personal and socio demographic factors. The study recommends
integrating health awareness programmes about smoking hazards in the medical education
curriculum.
Purpose: Lacunar infarcts is an important stroke subgroup with unique clinical and
pathologic features, but risk factors for lacunar infarcts have been rarely documented. To
address this matter, we studied 65 patients had lacunar infarction at Depa
rtment of
Neurology , Tishreen University Hospital , Lattakia , Syria , and 65 controls during the
period between May 2017 – May 2018 .
Methods: We obtained information concerning risk factor exposure status among the
patients by a structured questionnaire , we recorded age , sex , blood pressure , glucose ,
heart diseases , cigarette smoking , alcohol drinking , physical exercise for patiens and
controls .We do laboratory tests and ECG and echocardiography and CT brain or MRI .
Results: Significantly increasing the risk of lacunar stroke were hypertension
(P-value=0.0001) and (OR=9.9), Current smokers (P-value=0.002) and (OR=5.2), diabetes
(P-value=0.001) and (OR=5.3) , whereas frequent physical exercise was associated with a
significantly decreased risk) P-value=00001( and (OR=2.6). There was no risk of
lacunar stroke associated with heart disease (P-value=0.6) (OR=0.8) , high cholesterol (Pvalue=
1) and (OR=1) , alcohol drinking (P-value=0.7) and (OR=0.8).
Conclusions: Patients with hypertension or diabetes, current smokers, those who
have not heart disease, are at a higher risk of lacunar stroke, whereas those who undertake
regular physical exercise may be at lower risk.
