The antinociceptive effect and the mechanism of bee venom acupuncture (BVA)
on inflammatory pain, especially in the rat model of collagen-induced arthritis
(CIA), have not yet been fully studied. This study was designed to investigate
the antinociceptive effect and its mu-opioid and alpha(2)-adrenergic
mechanism of BVA in the CIA rat model. To induce CIA, male Sprague-Dawley
rats were immunized with bovine type II collagen emulsified in Freund's incomplete
adjuvant followed by a booster injection 14 days later. The antinociceptive
effect was evaluated by tail flick latency (TFL). After induction of arthritis,
the inflammatory pain threshold decreased as time passed, and there was no
big change of the pain threshold after 3 weeks. Three weeks after the first
immunization, BVA (0.25 mg/kg) injected into the Zusanli acupoint (ST(36)) showed the antinociceptive effect. Furthermore, the
antinociceptive effect of BVA was blocked by yohimbine (alpha(2)-adrenergic
receptor antagonist, 2 mg/kg, i.p) pretreatment, but not by naloxone (mu-opioid
receptor antagonist, 2 mg/kg, i.p.) pretreatment. These results suggest that
BVA can relieve inflammatory pain in CIA and the antinociceptive effect of
BVA can be mediated by alpha(2)-adrenergic receptor.

The aim of this study was to assess the inhibitory effect of whole bee venom
(BV) on adjuvant-induced arthritis in the rat. Rats were divided into pre-apitherapy,
post-apitherapy and control experimental groups. The pre-apitherapy group
was subcutaneously stung with a honeybee (Apis mellifera L.) and the control
group was subcutaneously injected with 0.1 ml of physiological saline solution
one day prior to complete Freund's adjuvant (CFA) injection. The post-apitherapy
group was subcutaneously stung with a honeybee on day 14 after CFA injection.
When arthritis had developed in the rat, the post-apitherapy group was subcutaneously
administered whole BV every other day for a further 14 days. Clinical signs,
hematological values and radioglogical features were observed during the entire
experimental period. In the pre-apitherapy group, the development of inflammatory
edema and polyarthritis was inhibited. Significant differences in lameness
score, hind paw edema volume and radiological features were observed between
control and pre-apitherapy rats. White blood cell counts indicated that the
degree of leucocytosis was significantly different between the pre-apitherapy
and control groups (p < 0.01). Inflammatory edema, polyarthritis and bone
change into the right hind paw were effectively inhibited in pre-apitherapy
rats during the two-week period post-CFA injection. In conclusion, whole BV
was found to inhibit arthritic inflammation and bone changes in the rat. This
may be an alternative treatment for arthritis in humans.

Bee venom (BV) has been used traditionally for the control of pain and inflammation
in various chronic inflammatory diseases, including rheumatoid arthritis (RA)
in Oriental medicine. However, it is still unclear how BV exerts its beneficial
effects on the clinical course of RA patients. To investigate the effect of
BV on the treatment of rheumatoid synovitis, we examined the inhibition of
cell growth and induction of apoptosis in human rheumatoid synovial fibroblasts.
Rheumatoid synovial fibroblasts were surgically obtained from patients with
RA. Cell proliferation and viability were assessed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium
bromide (MTT) assay. The apoptosis of synovial cells treated with 10 microg/ml
BV for 24 h was identified by 4,6-diamidino-2-phenylindole (DAPI) staining,
terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling (TUNEL)
assay, DNA fragmentation assay, RT-PCR, and Western blot analysis. It was
demonstrated that rheumatoid synovial cells treated with
10 microg/ml BV for 24 h exhibited apoptotic features and fragmentation of
DNA. In addition, BV induces apoptosis in rheumatoid synovial cells
through a decrease in BCL2 expression and an increase in BAX and caspase-3
(CASP3) expression. It is suggested that BV inhibits the proliferation of
rheumatoid synovial cells through induction of apoptosis by CASP3 activation.

The effect of bee venom aqua-acupuncture (BVA) (api-toxin), a traditional
immunosuppressive Korean aqua-acupuncture, on the bone function in human osteoblastic
cells was studied. To provide insights into the effect of BVA on aromatase
activity in bone-derived cells, we examined the human leukaemic cell line
FLG 29.1, which is induced to differentiate toward the osteoclastic phenotype
by TPA and TGF-beta1, and the primary first-passage osteoblastic cells (hOB).
Southern blot of RT-PCR products with a 32P-labeled cDNA probe for the human
aromatase demonstrated that FLG 29.1 and hOB cells express aromatase mRNA.
Gene expression and enzyme activity were stimulated in a time-dependent fashion
by 5.0 microl/ml BV and by either 1-50 nM TPA or
0.01-0.5 ng/ml TGF-beta1, with maximal responses after 2-3 h exposure. After
24 h incubation of the cells in the absence of these stimuli the aromatase
mRNA and the protein were barely detectable. These findings demonstrate that
cells of the osteoclastic lineage synthesize aromatase in vitro by the local
cytokine of TGF-beta1 and BVA. These can offer an explanation for the lack
of development of osteoarthritis in BVA-treated patients.

Recently, the antinociceptive and anti-inflammatory efficacy of bee venom
(BV, Apis mellifera) has been confirmed in rodent models of inflammation and
arthritis. Interestingly, the antinociceptive and anti-inflammatory effect
of whole BV can be reproduced by two water-soluble fractions of BV (>20
kDa:BVAF1 and<10 kDa: BVAF3). Based on these scientific findings,
BV and its effective water-soluble fractions have been proposed as potential
anti-inflammatory and antinociceptive pharmaceuticals. While BV's anti-inflammatory
and antinociceptive properties have been well documented, there have been
no careful studies of potential, side effects of BV and its fractions when
administered in the therapeutic range (BV, 5 microgram/kg; BVAF1, 0.2 microgram/kg:
BVAF3, 3 microgram/kg; subcutaneous or intradermal). Such information is critical
for future clinical use of BV in humans. Because of this paucity of information,
the present study was designed to determine the general pharmacological/physiological
effects of BV and its fractions administration on the rodent central nervous,
cardiovascular, respiratory and gastrointestinal system. Subcutaneous BV and
its fractions treatment did not produce any significant effects on general
physiological functions at the highest dose tested (200-fold and 100-fold
doses higher than that used clinically, respectively) except writhing test.
These results demonstrate that doses of BV or BV subfractions in the therapeutic
range or higher can be used as safe antinociceptive and anti-inflammatory
agents.

Microarray
analysis of gene expression in chondrosarcoma cells treated with bee venom.
Yin
CS, Lee
HJ, Hong

HG.
Department of Acupuncture,
Bee venom (BV) has a broad array of clinical applications in Korean medicine,
including treatment of inflammatory conditions such as arthritis. The final
common pathway of many arthropathies is the destruction of articular cartilage
and consequent loss of articular function. Chondrocyte dysfunction plays a
key role in the pathogenesis of such disorders. To explore the global gene
expression profiles in a human chondrocyte-like cell line treated with BV,
microarray analysis was performed. The HTB-94 human chondrosarcoma cells were
treated with BV, lipopolysaccharide (LPS), or both. Of the 344 genes profiled
in this study, with a cut-off level of 4-fold change in the expression, (1)
35 were downregulated following BV treatment, (2) 16 were upregulated and
7 downregulated following LPS treatment, and (3) 32 were downregulated following
co-stimulation of BV and LPS. The results of the present study shows that
treatment of BV reversed the LPS-induced upregulation of such genes as interleukin-6
(IL-6) receptor, matrix metalloproteinase 15 (MMP-15), tumor necrosis factor
(ligand) superfamily-10, caspase-6 and tissue inhibitor of metalloproteinase-1
(TIMP-1). It is thought that microarrays will play an ever-growing role in
the advance of our understanding of the pharmacologic actions of BV in the
treatment of arthritis.

Antiarthritic
effect of bee venom: inhibition of inflammation mediator generation by suppression
of NF-kappaB through interaction with the p50 subunit.

OBJECTIVE: To investigate the molecular mechanisms of the antiarthritic effects
of bee venom (BV) and melittin (a major component of BV) in a murine macrophage
cell line (Raw 264.7) and in synoviocytes obtained from patients with rheumatoid
arthritis. METHODS: We evaluated the antiarthritic effects of BV in a rat
model of carrageenan-induced acute edema in the paw and in a rat model of
chronic adjuvant-induced arthritis. The inhibitory effects of BV and melittin
on inflammatory gene expression were measured by Western blotting, and the
generation of prostaglandin E(2) (PGE(2)) and nitric
oxide (NO) and the intracellular calcium level were assayed. NF-kappaB DNA
binding and transcriptional activity were determined by gel mobility shift
assay or by luciferase assay. Direct binding of BV and melittin to the p50
subunit of NF-kappaB was determined with a surface plasmon resonance analyzer.
RESULTS: BV (0.8 and 1.6 mug/kg) reduced the effects of carrageenan- and adjuvant-induced
arthritis. This reducing effect was consistent with the inhibitory effects
of BV (0.5, 1, and 5 mug/ml) and melittin (5 and 10 mug/ml) on lipopolysaccharide
(LPS; 1 mug/ml)-induced expression of cyclooxygenase 2, cytosolic phospholipase
A(2), inducible NO synthase, generation of PGE(2)
and NO, and the intracellular calcium level. BV and melittin prevented LPS-induced
transcriptional and DNA binding activity of NF-kappaB via the inhibition of
IkappaB release and p50 translocation. BV (affinity [K(d)]
= 4.6 x 10(-6)M) and melittin (K(d) = 1.2 x 10(-8)M) bound directly to p50.
CONCLUSION: Target inactivation of NF-kappaB by directly binding to the p50
subunit is an important mechanism of the antiarthritic effects of BV.

Bee venom (BV) has been used to relieve pain and reduce inflammation in traditional
Oriental medicine, especially in chronic inflammatory diseases such as rheumatoid
arthritis (RA). We previously reported that the BV injection into a traditional
acupuncture point (Zusanli) reduced arthritis-associated edema and nociceptive
responses in Freund's adjuvant-induced arthritis in rats (Kwon et al., 2001).
This study was designed to evaluate the anti-inflammatory and anti-cytokine
effect of BV on a murine type-II collagen-induced arthritis (CIA) model. Male
mice were immunized by spontaneous injection of 100 microg of an emulsion
of bovine type-II collagen and complete Freund's adjuvant (CFA), with a booster
injection after 2 weeks. In the experimental group, 0.1 ml BV was injected
at acupuncture point (Zusanli) near both knees twice a week for a total of
5 times. In the control group, normal saline was injected at the same frequencies.
These injections began 5 weeks after the first collagen injection. Starting
the 3rd week after the first collagen injection, we examined limb swelling
and severity of arthritis twice a week. At 8 weeks, mice were sacrificed and
synovial tissue was examined with the light microscope and serum cytokines
(IL-1beta and TNF-alpha) were measured by ELISA. The incidence of arthritis,
the mean arthritis index and the number of arthritic limbs were significantly
lower in the treatment compared to the control group (63% versus 75%, 3.4%
versus 8.5%, 23% versus 75%, respectively). Among the serum proinflammatory
cytokines, the production of TNF-alpha in the BV group was suppressed compared
to the control group (59 +/- 4.5 versus 99.5 +/- 6.5, p < 0.05), but IL-1beta
was not suppressed. The examination of the histopathology of the joints of
murine CIA showed decreased inflammation signs and less lymphocyte infiltration
after BV acupuncture therapy. Acupuncture therapy with BV suppressed the development
of arthritis and caused inhibition of the immune responses in type-II collagen-induced
arthritis.

Inhibition of COX-2 activity and proinflammatory cytokines (TNF-alpha
and IL-1beta) production by water-soluble sub-fractionated parts from bee
(Apis mellifera) venom.
Nam KW, Je KH, Lee JH, Han HJ, Lee HJ, Kang SK, Mar W.
Natural Products Research Institute,
Bee venom is used as a traditional medicine for treatment of arthritis. The
anti-inflammatory activity of the n-hexane, ethyl acetate, and aqueous partitions
from bee venom (Apis mellifera) was studied using cyclooxygenase (COX) activity
and pro-inflammatory cytokines (TNF-alpha and IL-1beta) production, in vitro.
COX-2 is involved in the production of prostaglandins that mediate pain and
support the inflammatory process. The aqueous partition of bee venom showed
strong dose-dependent inhibitory effects on COX-2 activity (IC50 = 13.1 microg/mL),
but did not inhibit COX-1 activity. The aqueous partition was subfractionated
into three parts by molecular weight differences, namely, B-F1 (above 20 KDa),
B-F2 (between 10 KDa and 20 KDa) and B-F3 (below 10 KDa). B-F2 and B-F3 strongly
inhibited COX-2 activity and COX-2 mRNA expression in a dose-dependent manner,
without revealing cytotoxic effects. TNF-alpha and IL-1beta,
are potent pro-inflammatory cytokines and are early indicators of the inflammatory
process. We also investigated the effects of three subfractions on TNF-alpha
and IL-1beta production using ELISA method. All three subfractions, B-F1,
B-F2 and B-F3, inhibited TNF-alpha and IL-1beta production. These results
suggest the pharmacological activities of bee venom on anti-inflammatory process
include the inhibition of COX-2 expression and the blocking of pro-inflammatory
cytokines (TNF-alpha, and IL-1beta) production.

In two previous reports, we have demonstrated that injection of bee venom
(BV) into an acupoint produces a significant antinociceptive and anti-inflammatory
effect in both a mouse model of visceral nociception and a rat model of chronic
arthritis. The present study was designed to evaluate the potential antinociceptive
effect of BV pretreatment on formalin-induced pain behavior and it associated
spinal cord Fos expression in rats. Adult Sprague-Dawley
rats were injected with BV directly into the Zusanli (ST36) acupoint or into
an arbitrary non-acupoint located on the back. BV pretreatment into the Zusanli
acupoint significantly decreased paw-licking time in the late phase of the
formalin test. In contrast, BV injected into a non-acupoint in the back region
did not suppress the paw-licking time. In addition, BV pretreatment into the
Zusanli acupoint markedly inhibited spinal cord Fos
expression induced by formalin injection. These findings indicate that BV
pretreatment into the Zusanli acupoint has an antinociceptive effect on formalin-induced
pain behavior.

male rats were injected with complete Freund's adjuvant (CFA). Adjuvant arthritis
was produced by a single subcutaneous injection of I mg Mycobacterium butyricum
suspended in 0.1 ml paraffin oil into the right hind paw. Righting reflex
was uniformly lost and considered to be the point of arthritis development

The water-soluble
fraction of bee venom produces antinociceptive and anti-inflammatory effects
on rheumatoid arthritis in rats.

National University, Suwon, South Korea.
We recently demonstrated that bee venom (BV) injection into the Zusanli acupoint
produced a significantly more potent anti-inflammatory and antinociceptive
effect than injection into a non-acupoint in a Freund's adjuvant induced rheumatoid
arthritis (RA) model. However, the precise BV constituents responsible for
these antinociceptive and/or anti-inflammatory effects are not fully understood.
In order to investigate the possible role of the soluble fraction of BV in
producing the anti-arthritic actions of BV acupuncture, whole BV was extracted
into two fractions according to solubility (a water soluble fraction, BVA
and an ethylacetate soluble fraction, BVE) and the BVA fraction was further
tested.Subcutaneous BVA injection (0.9 mg/kg/day) into the Zusanli acupoint
was found to dramatically inhibit paw edema and radiological change (i.e.
new bone proliferation and soft tissue swelling) caused by Freund's adjuvant
injection. BVA treatment also reduced the increase in serum interleukin-6
caused by RA induction to levels observed in non-arthritic animals. In addition,
BVA therapy significantly reduced arthritis-induced nociceptive behaviors
(i.e. nociceptive scores for mechanical hyperalgesia and thermal hyperalgesia).
Finally, BVA treatment significantly suppressed adjuvant-induced Fos
expression in the lumbar spinal cord at 3 weeks post-adjuvant injection. In
contrast, BVE treatment (0.05 mg/kg/day) failed to show any anti-inflammatory
or antinociceptive effects on RA.The results of the present study demonstrate
that BVA is the effective fraction of whole BV responsible for the antinociception
and anti-inflammatory effects of BV acupuncture treatment. Thus it is recommended
that this fraction of BV be used for long-term treatment of RA-induced pain
and inflammation. However, further study is necessary to clarify which constituents
of the BVA fraction are directly responsible for these anti-arthritis effects.

The aim of this investigation was to determine whether bee venom (BV) administered
directly into an acupoint was a clinically effective and safe method for relieving
the pain of patients with knee osteoarthritis (OA) as compared to traditional
needle acupuncture. We evaluated the efficacy of BV acupuncture using both
pain relief scores and computerized infrared thermography (IRT) following
4 weeks of BV acupuncture treatment. We observed that a significantly higher
proportion of subjects receiving BV acupuncture reported substantial pain
relief as compared with those receiving traditional needle acupuncture therapy.
Furthermore, the IRT score was significantly improved and paralleled the level
of pain relief.

From a clinical perspective, the alternative forms of acupoint stimulation
including electroacupuncture, moxibustion and acupressure appear to have more
potent analgesic effects than manual needle acupuncture. Bee venom (BV) injection
has also been reported to produce persistent nociceptive stimulation and to
cause neuronal activation in the spinal cord. In previous study, we observed
that BV stimulation into acupoint, namely BV acupuncture or Apipuncture, produced
more potent anti-inflammatory and antinociceptive potency in rodent arthritis
model as comparing with that of non-acupoint injection. Based on previous
report, we decided to further investigate that BV injection into an acupoint
produces antinociception as a result of its potent chemical stimulatory effect
in both abdominal stretch assay and formalin test. Different doses of BV were
injected into an acupoint or a non-acupoint 30 min prior to intraplantar formalin
injection or intraperitoneal acetic acid injection. Using the abdominal stretch
assay, we found that the high dose of BV (1:100 diluted in 20microl saline)
produced a potent antinociceptive effect irrespective of the site of BV injection.
In contrast the antinociceptive effect observed in both the writhing and formalin
tests following administration of a low dose of BV (1:1000 diluted in 20microl
saline) was significantly different between acupoint and non-acupoint sites.
BV injection into an acupoint (Zhongwan, Cv. 12) was found to produce significantly
greater antinociception than non-acupoint injection (

Bee venom
pretreatment has both an antinociceptive and anti-inflammatory effect on carrageenan-induced
inflammation.
Lee JH, Kwon YB, Han HJ, Mar WC, Lee HJ, Yang IS, Beitz AJ, Kang SK.
Department
of Veterinary Physiology,
Although the injection of bee venom (BV) has been reported to evoke tonic
pain and hyperalgesia, there is conflicting evidence in the literature indicating
that BV can also exert an anti-inflammatory and antinociceptive
effects on inflammation. In this regard, BV has been traditionally
used in Oriental medicine to relieve pain and to treat chronic inflammatory
diseases such as rheumatoid arthritis. The present study was designed to test
the hypothesis that BV induces acute nociception under normal conditions,
but that it can serve as a potent anti-inflammatory and antinociceptive agent
in a localized inflammatory state. The experiments were designed to evaluate
the effect of BV pretreatment on carrageenan (CR)-induced acute paw edema
and thermal hyperalgesia. In addition, spinal cord Fos expression induced by peripheral inflammation was quantitatively
analyzed. In normal animals subcutaneous BV injection into the hindlimb was
found to slightly increase Fos expression in the
spinal cord without producing detectable nociceptive behaviors or hyperalgesia.
In contrast pretreatment with BV (0.8 mg/kg) 30 min prior to CR injection
suppressed both the paw edema and thermal hyperalgesia evoked by CR. In addition,
there was a positive correlation between the percent change in paw volume
and the expression of Fos positive neurons in the
spinal cord. These results indicate that BV pretreatment has both antinociceptive
and anti-inflammatory effects in CR-induced inflammatory pain. These data
also suggest that BV administration may be useful in the treatment of the
pain and edema associated with chronic inflammatory diseases.

Bee venom (BV) has traditionally been used in Oriental medicine to relieve
pain and to treat inflammatory diseases such as rheumatoid arthritis (RA).
While several investigators have evaluated the anti-inflammatory effect of
BV treatment, the anti-nociceptive effect of BV treatment on inflammatory
pain has not been examined. Previous studies in experimental animals suggest
that the therapeutic effect of BV on arthritis is dependent on the site of
administration. Because of this potential site specificity, the present study
was designed to evaluate the anti-nociceptive effect of BV injections into
a specific acupoint (Zusanli) compared to a non-acupoint in an animal model
of chronic arthritis.

Secreted
phospholipase A(2) induces vascular endothelial cell
migration.

and
Secreted phospholipase A(2) (sPLA(2)) regulates a
variety of cellular functions. The present investigation was undertaken to
elucidate the potential role of sPLA(2) in endothelial
cell (EC) migration. Bovine aortic endothelial cells (BAECs) exposed to sPLA(2) placed in the lower compartment of a modified Boyden
chamber displayed increased migration compared to cells exposed to vehicle.
The effect of sPLA(2) on EC migration was time and
dose dependent. Migration of BAECs was observed at 30 minutes, increased over
1 to 2 hours, and declined thereafter. At 2 hours of stimulation, sPLA(2)
(0.01-2 micromol/L) induced 1.2- to 3-fold increased cell migration compared
with media alone. Among the different sPLA(2)s tested,
bee venom, Naja naja, and porcine and human pancreatic PLA(2)s all evoked
a migratory response in ECs. Moreover, human synovial fluid, obtained from
patients with arthritis and containing sPLA(2) activity,
induced EC migration. Migration of ECs was significantly reduced after exposure
to a catalytic site mutant of pancreatic sPLA(2)
with decreased lipolytic activity as compared to wild-type sPLA(2). Similarly,
pretreatment of human synovial fluid with p-bromophenacyl bromide, an irreversible
inhibitor of sPLA(2), markedly decreased the ability
of human synovial fluid to stimulate EC migration. Moreover, migration of
ECs was stimulated on exposure to hydrolytic products of sPLA(2) activity including arachidonic acid, lysophosphatidic
acid, and lysophosphatidylcholine. These findings suggest that sPLA(2)
plays a physiologic role in induction of EC migration. Moreover, the effects
of sPLA(2) on EC migration are mediated, at least
in part, by its catalytic activity. (Blood. 2000;96:3809-3815)

The marine product petrosaspongiolide
M is a novel inhibitor of phospholipase A2 (PLA2), showing selectivity for
secretory PLA2 versus cytosolic PLA2, with a potency on the human synovial enzyme (group II) similar to
that of manoalide. This compound was more potent than manoalide on bee venom
PLA2 (group III) and had no effect on group I enzymes (Naja naja and porcine
pancreatic PLA2). Inhibition of PLA2 was also observed in vivo in the zymosan-injected
rat air pouch, on the secretory enzyme accumulated in the pouch exudate. Petrosaspongiolide
M decreased carrageenan paw edema in mice after the oral administration of
5, 10, or 20 mg/kg. This marine metabolite (0.01-1.0 micromol/pouch) induced
a dose-dependent reduction in the levels of prostaglandin (PG)E2,
leukotriene B4, and tumor necrosis factor-alpha in the mouse air pouch injected
with zymosan 4 h after the stimulus. It also had a weaker effect on cell migration.
The inflammatory response of adjuvant arthritis was reduced by petrosaspongiolide
M, which also inhibited leukotriene B4 levels in serum and PGE2 levels in
paw homogenates. In contrast with indomethacin, this marine compound did not
reduce PGE2 levels in stomach homogenates. Petrosaspongiolide M is a new inhibitor
of secretory PLA2 in vitro and in vivo, with anti-inflammatory properties
in acute and chronic inflammation.
