Immune-regulating effects of securidaca inappendiculata
hassk in rats☆
Li Yong-wen, Li Li

Abstract
BACKGROUND: Many kinds of immunosuppressive drugs, such as cyclosporine A, are commonly used against rejection
in organ transplantation, but are lack of selectivity and specificity. They have potent effective on primary immune response
rather than on secondary immune response.
OBJECTIVE: To develop cell models with low immunity by adding cyclosporine A into splenic lymphocytes for observing
the immune-regulating effects of rat serum containing securidaca inappendiculata hassk on lymphocytes.
DESIGN: Randomized and controlled Chinese medicine serum pharmacological experiment.
TIME AND SETTING: Performed at the Laboratory Center for Medical Science, Guangxi Medical University between
June and September 2007.
MATERIALS: Forty healthy adult Wistar rats were selected for preparation of serum containing securidaca inappendiculata
hassk, and the splenic lymphocytes originated from eight healthy adult Kunming mouse were used for testing immunological
function. Securidaca inappendiculata hassk decoction (Lot No. 20061220) was kindly gifted by Yulin Pharmaceutical
Factory, China. Concanavalin A [ConA, Fluka, Switzerland Lot No.10578] was the product of Fluka Company, Switzerland;
Cyclosporine A (100 mg/L, Lot No. 20070108) was purchased from the North China Drugs Manufacture Group, China.
METHODS: Rats were intragastrically administered securidaca inappendiculata hassk 10.0, 5.0, 2.5 g/kg/d for a total of 7
days, to prepare rat serum containing different levels of securidaca inappendiculata hassk. 20 mg/LConA (50 μL/well),
serum containing securidaca inappendiculata hassk (50 μL/well), cyclosporine A (100 μL/well), and splenic lymphocyte
suspension (100 μL/well) were added into 96-well plate. Serum without medicine was taken as control.
MAIN OUTCOME MEASURES: 96-well plate was inoculated for 68 hours after sample adding and for another 4 hours
after application of methyl thiazolyl tetrazolium (MTT). Absorbance (A) value was determined using enzyme reader.
RESULTS: A value was significantly higher in the non-medicine blood serum + Con A group than in the non-medicine
blood serum (P < 0.01).The medicine blood serum +Con A group had significantly higher A value than non-medicine blood
serum +Con A group ( P < 0.01). A value was significantly lower in the non-medicine blood serum+ Con A+ cyclosporine A
group than in the non-medicine blood serum+ Con A group ( P < 0.01) but was higher than in the non-medicine blood serum
group ( P < 0.05). High- and middle-dose medicine serum + Con A+ cyclosporine A group had higher A value than the
non-medicine blood serum + cyclosporine A group (P < 0.05).
CONCLUSION: Securidaca inappendiculata hassk can improve the immune function of normal mice and elevate the lower
immune function induced by cyclosporine A, which indicates that securidaca inappendiculata hassk has a positive regulatory
effect.


INTRODUCTION

At present, immunosuppressive drugs commonly
used in clinics such as cyclosprine A share the
following common shortcomings: ①Most
immunosuppressives can inhibit both normal and
abnormal immune response of the body due to its
lack of selectivity and specificity. That is the reason
why these drugs can induce infection, increase
incidence of cancer and affect the function of
reproductive system due to its effects of reducing
normal immunity of the body. ②Most
immunosuppressives have strong action to primary
immune response and weak action to secondary
immune response. Chinese medicine is rich in
resources and used for a long time. Searching for
effective, low-toxicity, inexpensive and new
immunosuppressives to prevent rejection and
complication and overcome severe adverse reaction
caused by long-term application of
immunosuooressuves is a hot spot in the study of
Chinese medicine.
Securidaca inappendiculata hassk belongs to the
polygalaceae, the aspiration race of cicada wing
cane, which distributes in India, Burma, Vietnam,
Indonesia and Malaysia. While in our country it
widely grows in Guangdong, Hainan, Guangxi and
Yunnan provinces [1].
So far, there are seven types of chemical
constituents from the vine plants confirmed in
securidaca inappendiculata hassk, such as
flavonoids, xanthone, and terpene, steroidal
glycosides and its glycosides, sugar and
glycosides, alkaloids, organic acid and its
derivatives[2-4]. It is reported that its
pharmacological effects include anti-HIV,
anti-allergic and anti-leukemia, anti-cancer,
antibacterial and other anti-inflammatory
factors [5-8]. In order to further investigate the
mechanism of action of immune regulating effects
of securidaca inappendiculata hassk, we studied
how securidaca inappendiculata hassk enhance the
immune function of normal mouse, resist
cyclosprine A-caused low immunity, and
up-regulate immunity, thereby providing evidence
for clinical application.

Methods
Preparation of drug-containing serum
Serum pharmacology method was used. Wistar rats were
administered securidaca inappendiculata hassk (10.0, 5.0 ,
2.5 g/kg/d)and physiological saline for 7 days. Two hours
after the last intragastric administration (prior to intragastric
administration, water but not food was available) and
subsequent to ethyl ether anesthesia, rat blood was taken
from the abdominal aorta, and serum was isolated by
low-speed centrifugation (2 500 r/min, 15 minutes). Next,
the serum was inactivated for 30 minutes at 56 ℃ and
filtered using 0.45 μm millipore filter and 0.22 μm
millipore filter, and finally preserved at –20 ℃.
Detection of splenic lymphocyte proliferation
Mouse splenic lymphocytes were collected. Total number of
cells was obtained, and simultaneously RPMI 1640 (10% fetal
bovine serum volume was calculated to adjust cell
concentration. 20 μg/mL ConA (50 μL/well), serum
containing securidaca inappendiculata hassk (50 μL/well),
cyclosporine A (100 μL/well), and splenic lymphocyte
suspension (100 μL/well). 96-well plate was cultured at 37℃
in a 5% CO2-containing incubator for 68 hours after sample
adding and for another 4 hours after application of methyl
thiazolyl tetrazolium (MTT). Next, 100 μL of hydrochloric
acid/isopropyl alcohol solution (1:300) was added.
Absorbance (A) was determined using an enzyme reader.
Cyclosprine A inhibition rate (%) = (1-A570 value in the
experimental group/A570 value in the blank control group)
×100;Stimulation index = (average A value for the ConA
stimulation well/average A value for the control well)-1.

Design, enforcement and evaluation: Li Yong-wen
designed this study. Li Li and Li Yong-wen performed the
experiments. Professor Huang Ren-bin, doctor’s tutor, who
was from the Department of Pharmacology, Guangxi Medical
University, participated in the evaluation.

Main outcome measures: Splenic lymphocyte
proliferation.

Statistical analysis: Analysis of variance was performed
using SPSS 10.0 software. All experimental data were
expressed as Mean ± SD.

Table 1 shows that A value was significantly higher in the
non-medicine blood serum + Con A group than in the
non-medicine blood serum (P < 0.01). A value was
significantly higher in the medicine blood serum + Con A
group than in the non-medicine blood serum+ Con A group
(P < 0.01). This indicates that securidaca inappendiculata
hassk can enhance immune function. A value was
significantly lower in the non-medicine blood serum+ Con
A+ cyclosporine A group than in the non-medicine blood
serum+ Con A group ( P < 0.01) but was higher compared
with the non-medicine blood serum group ( P < 0.05).
High- and middle-dose medicine serum + Con A+
cyclosporine A group had higher A value than the
non-medicine blood serum + cyclosporine A group (P <
0.05). This indicates that securidaca inappendiculata hassk
can resist the low immune function induced by
cyclosporine A, which indicates that securidaca
inappendiculata hassk has a positive regulatory effect.
Factors that may affect the outcomes of study
Carelessness may lead to pollution during the whole
operation. The primary measures in preventing pollution
are as follows: ① Equipment and solution should be
sterilized before use. ② Operators should wear mask and
hat. ③The mouth of culture flask should be sterilized with
75% ethanol. ④Normal operation.

DISCUSSION

Rats, rabbits, and guinea pigs are mostly used to prepare
drug-containing serum in the pharmacological experiments.
The animals used for serum preparation should be
consistent with those used for ex vivo preparation of organs,
tissue, and cells. Thus, the physiological and chemical
differences between animal serums or between animal
serum and human serum can be reduced or avoided, thereby
reducing the immune reactions caused by species
differences and enhancing the reliability of experimental
results.
In the present study, rats were used for preparing
drug-containing serum because they could provide enough
serum to satisfy the experimental requirements.
The present study used drug-containing rat serum to
observe the effects of securidaca inappendiculata hassk on
mouse splenic lymphocyte transformation rate. To better
study the mechanism of action of securidaca
inappendiculata hassk on enhancing mouse immunity, cell
models with low immunity were established by adding
cyclosporine A into splenic lymphocytes to observe the
immune-regulating effects of rat serum containing
securidaca inappendiculata hassk on lymphocytes. Results
demonstrated that securidaca inappendiculata hassk can
improve the immune function of normal mice and elevate
the low immune function induced by cyclosporine A, which
indicates that securidaca inappendiculata hassk, in
particular at high dose, has a positive regulatory effect.
