the most concerns about the use of implant treatments is bacterial leakage
between the fixture and abutment at the connection. The aim of this study was
to evaluate the bacterial leakage rate at the interface of ITI fixtures and
ITI, DIO and OSSTEM solid abutments. Materials and Methods: Thirty ITI
fixtures were divided into three groups (n=10) based on the abutment used. In
the first group, 10 solid ITI abutments, in the second group, 10 solid DIO
abutments, and in the third group, 10 solid OSSTEM abutments with similar
length and diameter were screwed into fixtures. Fixtures and abutments were
assembled and allowed to incubate in a solution of Streptococcus faecalis
(SF) for 5 days. In each group, two additional fixtures and two abutments were
selected and divided into two subgroups. In the negative-control subgroups,
abutments were not connected to fixtures and were placed into normal saline
solution. In the positive-control subgroup, abutments were not connected to
fixtures but were subjected to the same bacterial solution. After disconnection
of fixtures and abutments under sterile condition, abutments and fixtures were
placed in 1ml of normal saline solution and were vortexed for 30 sec. Then,
0.01 ml of each vortexed solution was cultured under appropriate conditions for
2 days. The CFUs (colony forming unit) were counted and recorded for each
abutment and fixture. Results: The average of CFUs for
each abutment and fixture counted in the first group was 13.6 and 20, in the
second group was 21.9 and 28.9, in the third group was 26.2 and 35.9, in positive
control subgroup was 152.3 and 178.3, and in negative-control subgroup was 0
and 0, respectively. There were not statistically significant differences
between the first and second groups but the leakage rate was statistically
different between first and third groups. Conclusion: The results of the
present study demonstrated that compatibility of DIO solid abutments on ITI
fixtures are acceptable but it is not the case for OSSTEM solid abutments and
the use of these abutments on ITI fixtures is not recommended. Background and Objective: One of

of diabetes mellitus that affects the life quality of patients. Nigella
sativa-derived thymoquinone exhibits antidiabetic
and anti-inflammatory effects. This study was designed to investigate the
antinociceptive effect of thymoquinone (TQ) in streptozotocin-diabetic rats. Materials and Methods: Rats were divided into control, high
dose TQ-treated control, diabetic, sodium salicylate (SS)-treated control and diabetic,
and high and low dose TQ-treated diabetic groups. TQ was administered i.p. at
doses of 2.5 and 5 mg/kg one week after diabetes induction by streptozotocin
for 5 weeks. Results: TQ treatment of diabetic rats reduced pain score
in acute and chronic phases of the formalin test (p < 0.05). Meanwhile, SS
administration significantly reduced pain score only at chronic phase of the
test (p < 0.01). Regarding hot tail immersion test, diabetic rats showed a
significant reduction in tail flick latency as compared to control ones
(p < 0.05) and TQ treatment of diabetic rats slightly increased this latency
relative to untreated diabetics but the existing difference was not
statistically significant. In addition, high-dose TQ significantly reduced serum
level of MDA in diabetic group (p < 0.05). Conclusion: Taken together, administration of TQ could
attenuate nociceptive score in both phases of formalin test in experimental
model of diabetes mellitus and has no obvious effect on thermal pain threshold
and part of this effect is exerted through attenuation of lipid peroxidation in
peripoheral tissues of the body. Background and Objective: Hyperalgesia is one of the signs

prevalent causes of death. A coronary artery
bypass surgery is a common treatment for this disease.
In addition, renal dysfunction can lead to increased mortality and post-operative
complications. This study aimed to identify the most important factors
influencing the mortality of patients who suffer from coronary artery disease
and to introduce a classification approach according to Classification Tree
(CART) model for predicting the mortality from this disease. Materials and Methods: This research was conducted based on the information
gathered from a cross-sectional study on 1390 patients (except
dialysis-dependent) who undergone coronary artery bypass grafting, admitted to
Cardiology ward of Shariati hospital during the years 2007-2010. The ordinary
logistic regression model and a classification tree were utilized for
predicting the probability of death in these patients. The SPSS version 18.0
and CART version 6.0 were used for data analysis. Results: In this study, the classification tree model (CART)
resulted in an accuracy of 90%. The patients with renal insufficiency,
intra-aortic balloon pump placement during and after surgery, prolonged
ventilation, and perfusion time over 160 were shown as the high-risk groups,
while those patients with heart ventricular post-operative complications
regarded as the medium-risk group. The sensitivity and specificity indices for
this model were 82% and 89%, respectively, while it was 80.4% and 88%,
respectively, for logistic model. Conclusion: In the present study, the logistic and decision
tree models led to nearly similar results, however, the decision tree model
seemed to be more accurate. The IABP (Intra-Aortic
Balloon Pump < /font>) was the most effective factor for mortality. The
mortality rate due to this factor during and after surgery for all patients was
19% and 54.1%, respectively. Background and Objective: Coronary artery disease is one of the most

prevalence and the fact that some of the patients remain refractory to
available antiepileptic drugs, design of suitable drugs, without unwanted side
effects is necessary. The use of plant extracts to treat diseases is proposed
as a therapeutic modality. Lavandula officinalis (L. officinalis),
commonly known as ustukhuddoos, has been used for a long time in traditional
medicine for some of nervous disorders like epilepsy. The aim of this
investigation was to provide a scientific basis for traditional use of L.
officinalis in epilepsy. Materials and Methods: A total of 60 male NMRI mice
weighing 25 to 30 g were randomly divided into six groups including: 1. PTZ, 2.
positive control (PTZ and valproate 150 mg/kg, as an anticonvulsant drug), 3 to
5. mice received L. officinalis
extract at three doses of 200, 400 and 800 mg/kg, and 6. mixed group which
received L. officinalis (200 mg/kg) and valproate (100 mg/kg) i.p. All
groups were kindled by 11 injections of PTZ (35 mg/kg) with an interval of 48
h. In the 12th injection, all groups
were tested for PTZ challenge dose (75 mg/kg). The phases of seizure (0-6),
threshold and duration of second and fifth phases were observed for 30 min after
PTZ injection. Results: Data analysis showed that L. officinalis
could reduce intensity and duration of seizures. In addition, there was no
phase 5 following L. officinalis treatment. Anti-epileptic effect in mix
group was not more than the L. officinalis group. Conclusion: Antiepileptic effect of chronic administration
of L. officinalis was established and it was more effective at a dose of
200 mg/kg than doses of 400 and 800 mg/kg. Meanwhile, L. officinalis
could reduce seizure phases better than valproic acid.

that underlies lifestyle in later periods of life. The aim of this study was
evaluation of the impact of a model based intervention on lifestyle among
adolescents. Materials and Methods: A group randomized clinical trial
for assessing the effect of educational intervention on 365 adolescents (192
females and 173 males) was designed. Adolescent life style questionnaire (ALQ)
and a demographic scale were used for data collection. Data were collected
before and two weeks after the intervention with regard to PRECEDE PROCEED
model. Statistical tests such as Chi 2, independent and paired t-test were used
by SPSS software version 17 for data analysis. Results: The mean age of adolescents was 15.77 years (SD =
0.74) years. A significant increment in lifestyle score was obtained between
before and after intervention among intervention groups (p < 0.01). The
standard mean of physical activity among males and the standard mean of social
support among females were higher than the other gender. Conclusion: The findings suggest that an educational
intervention based on PRECEDE PROCEED model may be effective for lifestyle
improvement among adolescents. In light of these findings, necessity of
gender-based healthy life style education among adolescents should be
considered further. Background and Objective: Adolescence is a critical period

considered further. https://daneshvarmed.shahed.ac.ir/article_1513_2b3bf3eee2475e03885a110e9acaab61.pdfShahed UniversityDaneshvar Medicine2716-972320120120420The effect of immobilization stress and Aloe vera extract on serum levels of LH, FSH and testosterone in male ratsThe effect of immobilization stress and Aloe vera extract on serum levels of LH, FSH and testosterone in male rats69741514FARahimAhmadiParisaTavakoliMahyarMafiJournal Article20200926 Background and Objective: Studies showed that Aloe vera
extract can influence reproductive functions in animals. The purpose of this
study was to determine the effect of immobilization stress and Aloe vera
extract on serum LH, FSH and testosterone levels in male rats. Materials and Methods: In this study, male Wistar rats were randomly divided into 9 groups including control, Aloe
vera extract receiving, Aloe vera extract and normal saline
receiving, acutely or chronically immobilized, acutely or chronically
immobilized and normal saline receiving and acutely or chronically
immobilized and Aloe vera extract receiving animals of 5 in each group.
Chronic immobilization was exerted 2h/day for 3 weeks and acute immobilization
was exerted 8h/day for one week. Aloe vera extract (625 mg/kg/body
weight) was taken by gavage feeding. Finally, blood samples were collected
using cardiac puncture method. Following serum collection, LH, FSH and
testosterone levels were measured by radioimmunoassay method. Data were compared between groups using
ANOVA. Results: Serum LH or testosterone level significantly
decreased in chronically or acutely immobilized rats compared to control
animals (p < 0.001) however, LH or testosterone serum level did not
significantly change in Aloe vera extract receiving and acutely or
chronically immobilized Aloe vera extract receiving animals compared
with control rats. Conclusion: Our findings showed that immobilization stress
reduces serum level of LH and testosterone however, intake of Aloe vera
can withstand against. Background and Objective: Studies showed that Aloe vera
