Acupuncture is helpful for functional bowel diseases, such as constipation and
diarrhea. However, the mechanisms of beneficial effects of acupuncture on
colonic function have barely ever been explored. A study was conducted to test
the hypothesis that electroacupuncture (EA) at ST-36 stimulates colonic motility
and transit through a parasympathetic pathway in conscious rats. Needles were
inserted at bilateral ST-36 (lower limb) or BL-21 (back) and electrically
stimulated at 10 Hz for 20 min. C-Fos expression in response to EA at ST-36 in
Barrington's nucleus of the pons was also studied. EA at ST-36, but not BL-21,
significantly increased the amplitude of motility at the distal colon.
Calculated motility index of the distal colon was increased to 132+/-9.9% of
basal levels (n=14, P<0.05). In contrast, EA at ST-36 had no stimulatory effects
in the proximal colon. EA at ST-36 significantly accelerated colonic transit
(GC=6.76+/-0.42, n=9, P<0.001), compared to EA atBL-21 (GC=5.23+/-0.39, n=7).
The stimulatory effect of EA at ST-36 on colonic motility and transit was
blocked by pretreatment with atropine. EA-induced acceleration of colonic
transit was also blocked by the extrinsic nerve denervation of the distal colon
(GC=4.69+/-0.33, n=6). The number of c-Fos immunopositive cells at the
Barrington's nucleus significantly increased in response to EA at ST-36 to
8.1+/-1.1 cells/section, compared to that of controls (2.4+/-0.5 cells/section)
(n=3, P<0.01). In conclusion, EA at ST-36 stimulates distal colonic motility and
accelerates colonic transit via a sacral parasympathetic efferent pathway
(pelvic nerve).
Patients With
Mental Disorders Often Seek Complementary Treatment
Rickhi, B. et al. Mental disorders and reasons for using
complementary therapy. Canadian Journal of Psychiatry 48(7):475-9.
The authors compared patients with and without mental
disorders who sought services from a complementary therapy practitioner in
regard to quality of life, reasons for seeking complementary therapies,
complaints, and physical conditions. Of the 826 new patients in the surveyed
clinic, 578 (70%) presented with a mental disorder. Patients with a mental
disorder perceived their quality of life as poorer and reported greater levels
of stress than did those without a mental disorder. The groups did not, however,
differ in their self-reported reasons for seeking complementary therapies, in
their complaints or in their physical conditions. Among patients with a mental
disorder, the major reasons for choosing complementary therapies were personal
preference, interest or belief in complementary therapies (44.3%) and perceiving
complementary therapies as a last resort (30.7%). Most patients with a mental
disorder saw a complementary practitioner for musculoskeletal and
connective-tissue disorders (44.1%), fatigue (26.6%) and headache (15.2%). The
most frequent physical illnesses among patients with a mental disorder were
diseases of the musculoskeletal system and connective tissue (42.6%). Like their
counterparts without a mental disorder, individuals with a mental disorder use
complementary therapies because of personal beliefs. The wide use of
complementary therapies among individuals with a mental disorder may be ascribed
to a poor quality of life and high levels of distress.
Acupuncture for
Managing Myofascial Pain and Headache
Audette, J.F. and Blinder, R.A. Acupuncture in the
management of myofascial pain and headache. Current Pain and Headache Reports
7(5):395-401.
Acupuncture encompasses a host of healing techniques that have
been practiced for more than 2000 years. Though many different techniques and
styles are in use in the West, scientifically studying acupuncture’s
effectiveness has proven problematic. This is partly because of the difficulty
in studying a dynamic, patient-centered system whose practice paradigms often
are artificially limited by the application of a reductionist methodology, which
is dictated by the standards of scientific enquiry. However, acupuncture, unlike
many indigent medical practices in the world, has withstood the test of time in
China and in the West, with many practitioners and patients reporting real
benefits for the conditions of headache and myofascial pain when treated by
acupuncture. This review provides a brief overview of acupuncture and what is
known of its effectiveness in treating headache and myofascial pain.
