Abstract: A various household appliances that containing CCl
4
can cause an inflammation. Utilization of date seed as
an anti-inflammatory agent has never been done. The aim of the study was to explore the peripheral blood
profiles of CCl
4
-induced wistar rat after steeped date seed treatment. An experimental study, post-test only
with control group design was used. Rats were assigned into 6 groups. There are negative control, positive
control, healthy control and treatment groups (dose 1; 3; 5 g/kg). Data collected were neutrophils,
lymphocytes and monocytes. The data was compared between the groups with the ANOVA test and was
followed by post hoc test. Induction of CCl
4
causes an increase of monocytes, neutrophils and decreased
lymphocytes number. Giving of dates seeds can reduce the number of monocytes and neutrophils but
increase of lymphocytes number. A dose of 3 g/kg of dates seed has the same effect with a control group
that given dexamethasone. The study showed for the first time anti-inflammatory of activity of steeped date
seed can change the peripheral blood profile. Steeping of date seeds can repair tissue damage due to CCl
4
exposure to be marked by accelerating the inflammatory process.
1 BACKGROUND
Exposure to toxic compounds, microorganisms,
tumors and trauma will lead to the onset of
inflammatory process. The inflammatory process
involves the role of peripheral blood cells to
minimize damage. From the site of infection,
chronic irritation and inflammation can also develop
into various types of cancer. Lymphocytes and
monocytes play an important role as predictor
survival of several diseases (Li et al., 2014). The
high levels of monocyte and/or neutrophil
infiltration may be accompanied by cytotoxicity,
angiostasis and tumor regression. The neutrophil-
lymph node ratio (NLR) is an index indicating
systemic inflammation (Unal et al., 2013).
Lymphocyte-monocyte ratio (LMR) is a useful
predictive factor for various cancers (Huang & Feng,
2015). The amount of eosinophil also correlates with
inflammation in bronchial asthma (Hef et al., 2017;
Katz et al., 2014). It suggests that the peripheral
blood profile is sensitive to identify the status of
systemic inflammation that occurs.
The peripheral blood features include eosinophil,
neutrophil, basophil, lymphocytes and monocytes.
Neutrophil acts as a bacterial phagocytosis and cell
destruction with lysosome enzymes. Basophil plays
an important role in hypersensitivity reactions.
While eosinophil produces antihistamines and plays
a role to prevent hypersensitivity reactions. Systemic
inflammation responses play an important role in the
progress of some diseases. Round blood examination
is easy to do, accurate and low cost. Inflammation
modifies the quality of the immune response.
Lymphocytes and monocytes are the major immune
cells in the inflammation response. The platelet-
lymphocyte ratio is a critical sign and associated
with a poor prognosis in some oncologic disorders
(Gary et al., 2013).
Recently, several cross sectional and cohort
studies have shown that the number of leukocytes is
positively associated with the prevalence and
incidence of metabolic syndrome (Sun et al., 2014).
The use of drugs as anti-inflammation cause various
side effects. One of the herb plants that allegedly act
as immunomodulators is date seeds. The date seeds
contain polyphenols (Ardekani et al., 2010) which

Saryono, Rahmawati, et al., 2017) and glucose (El-
Fouhil et al., 2011; El-Fouhil et al., 2010). However,
there have been no studies that explain the
peripheral blood parameters in inflammation due to
CCl
4
toxicity given the steeping of date palms
(Phoenix Dactylifera L.). Thus, this study aimed to
determine the profile of peripheral blood in mice
exposed to CCl
4
after being given the steeping of
date seeds.
2 METHODS
2.1 Preparation of Dates
The matured seeds of Phoenix dactylifera were
purchased from local market. Date palm seed of
Deglet Nour was selected and washed with tap
water, left to dry under the sun for one day. The
dried date palm seed was roasted and ground with
blender. Filtered the flour to obtain a fine powder.
2.2 Experimental Animal
Animal try in the form of white rat wistar grown
male, age about 2-3 months with the weight range
150-200 grams. Rats were adapted for one week and
placed in separate cages according to the group. All
animals were given food and drink according to their
needs (add libitum), and kept on a light dark cycle
12/12 hours. They were conducted based on
standardized protocols for experimental animal
studies. This study followed the principles of
laboratory established by Ethic Committee of
Medical School, University of Sebelas Maret,
Surakarta, Indonesia.
2.3 Research Design
The research was conducted using laboratory
experimental, pre and post-test with control group
design. The white rats were grouped into 6 groups,
healthy control (HC), negative control (NC),
positive control (PC), treatment dose 1 g/kg (T1),
treatment dose 3 g/kg (T3), and treatment dose 5
g/kg (T5). Prior to treatment, all groups were
induced with CCl
4
with a single dose of 0.2 ml/100g
except group E6. The treatment of giving the date
seeds was given for 14 days. Positive control using
dexamethasone dose 0.5 mg/kg.
2.4 Statistical Analysis
The measured data were peripheral blood profiles
including the absolute number of monocytes,
eosinophil, neutrophil segments and stems, as well
as lymphocytes with GIEMSA staining. The data
obtained will be compared between groups with one
way ANOVA test. The test results are said to be
significant if p <0.05. If there is a significant
difference, the data are analysed further by the post
hoc Least Significant Difference (LSD) test.
3 RESULTS
3.1 Phytochemical Test
Based on phytochemical test, steeping of date seed
powder contain more flavonoid and tannin.
Quantitative test results show that the steamed of
date seeds powder contain flavonoids that is 20.68
mg/mL (Table 1).
3.2 Peripheral Blood Profile
The mean score of monocytes in the healthy control
group was 1.8 ± 1.09 cells/mm
3
while in the CCl
4
-
induced group 2 ± 0.76 cells/mm
3
. In the CCl
4
-
induced group, the number of monocytes increased
but did not differ significantly with the healthy
group. After the treatment period, the group given 5
mg/kg of date seeds had the greatest decrease and
significant compared to the other groups. The lowest
monocyte rate was 1.8 ± 0.44 in the treatment group
with 5 mg/kg of date seeds (Table 2). Based on the
Anova test, it was found that there was a difference
of monocyte level between groups (p = 0.000). In
the negative control group, the number of monocytes
is still high. When compared with the positive
control group, administering the seeds of dates can
lower the number of monocytes larger. Based on the
LSD post hoc test, treatment group given 3 g/kg and
5 g/kg duck seeds were not significantly different
(Table 3), but generally the steeping of date palm
seeds decreased the number of monocytes.

There was a significant difference in the number of
lymphocytes between the healthy group and the
CCl
4
induced group (p<0.009). After the treatment
period, the average number of lymphocytes
increased (Table 4). Anova test results showed that
there were significant differences in the number of
lymphocytes between groups (p = 0.000). The
greatest increase occurred in the positive control
group given dexamethasone, and did not differ
significantly with the group given dose 3 g/kg
(Table 4). Based on the LSD post hoc test, the group
given doses of 1 and 5 g/kg date seeds were not
significantly different.

Based on the analysis of the overall data, giving
positive control (dexamethasone) showed no
difference with the giving of dill seeds dose 3 g/kg.
This means that the steeping dose of 3 g/kg doses is
proportional to the effects of dexamethasone drugs
as anti-inflammatory.
4 DISCUSSION
Epidemiological studies have shown that peripheral
blood profiles play a role in inflammation. CCl
4
toxicity can cause inflammation, but the mechanism
of using dates as anti-inflammatory in CCl
4
toxicity
is unclear. Giving CCl
4
effect on the occurrence of
acute inflammation, especially liver and kidney
organ. The number of monocytes and neutrophils
increased, while the number of lymphocytes
decreased after CCl
4
induction. These occur because
the inflammation caused spur the secretion of
monocytes and neutrophils to fight inflammation.
The presence of trauma to the cells will trigger an
inflammatory response, but some factors can boost
immunity so that it can reduce inflammation (Viana
et al., 2014).
In chronic inflammation, an increase in
monocytes in peripheral blood. After 24 hours, the
monocyte goes to the tissues and forms
macrophages. Macrophages will be activated by
TNF-α and activate iNOS (inducible nitrite oxide
synthase) and produce NO. The CCl
4
compound that
enters the liver will be converted to CCl
3
-
. CCl
3
bonding with NO will lead to new, more toxic
compounds, peroxinitrite (ONOO
-
). The ONOO
-
compound will cause endothelial poisoning,
resulting in decreased endothelial NO production.
This causes vasoconstriction so that the
inflammation gets worse. Giving dates flavonoids
(Yasin et al., 2015; Mohamed et al., 2014), can act
as antioxidants, by donating H+ to CCl
3
-
to become
neutral. This is what causes the number of
monocytes to return to normal.
Neutrophils are innate immunity components
that are abundant in the circulation. Neutrophils play
a role in the fight against invasive pathogens,
although it can also increase certain inflammatory
diseases. At the time of acute inflammation there is
an increase in the number of neutrophils that will
degrade the phospholipid membrane and form
arachidonic acid. With the help of the enzyme
cyclooxygenase-2 (COX2), arachidonic acid is
converted to prostaglandin. An increase in the
number of neutrophils is activated by IL-1β pro-
inflammatory cytokines. Along with cell repair by
the body's immune system, the number of
neutrophils will decrease. Some types of diseases
accompanied by high neutrophils have more severe
clinical outcome problems than controls such as
pain, bleeding, infarction and death (Zhang et al.,
2016). The results showed that neutrophil
recruitment to the site of infection was enhanced by
serotonin delivered by platelets in innate immune
reactions (Duerschmied et al., 2017). Several studies
have clarified the association of neutrophils with
prognostic diseases (Hashimoto et al., 2013; Li et
al., 2014; Jiang et al., 2015).
Increasing the number of lymphocytes at a time
of chronic inflammation is due to the immune
system trying to form antibodies as a defense against
CCl
4
radicals. But after the seeding of the date palm,
the free radicals CCl
3
-
decreases and the
lymphocytes return to normal. Baldness dates palm
seeds contain many flavonoids that can act as
antioxidants (Tang et al., 2013). This is evident from
previous research that the steeping of date palm
seeds can reduce malondialdehyde as a free radical
oxidation product and increase antioxidant enzymes
(Saryono, Hisni, et al., 2017). High leukocyte
content, neutrophil count and high neutrophil-

lymphocyte ratios correlated with failure of ST
elevation myocardial infarction (STEMI). This
indicator is a good failure predictor of the case
(Ghaffari et al., 2014). Other studies have shown
that leukocytes play a role in the generation of
oxidative stress and inflammation in diabetic
mellitus patients (Shurtz-Swirski et al., 2001).
5 CONCLUSIONS
CCl
4
toxicity can lead to visible inflammation in the
presence of an increase in the number of monocytes,
neutrophils and decreased lymphocytes. Giving of
dates seeds can reduce the number of monocytes,
neutrophils and increase lymphocytes. Steeped of
palm seeds can repair tissue damage due to CCl
4
exposure in animals that to be marked by
accelerating the inflammatory process. The date seed
steeped of 3 g/kg have an comparable to the effects
of the drug dexamethasone as anti-inflammatory.
Implication: The use of date palm seed as anti-
inflammatory can be given in the form of steeping.
The first study to look at the effects of date seed as
anti-inflammatory based on peripheral blood profiles
can be used as an early reference for further
research.
