Electroacupuncture on Gastric Motility and Heart Rate Variability in Conscious
Imai K, et al. Department of Surgery, Duke University, Durham,

To clarify the mechanism of site-specific effects of acupuncture on gastric
motor function, we studied the simultaneous recording of gastric motility and
electrocardiogram (ECG) for heart rate variability (HRV) analysis in conscious
rats. Gastric motility and ECG were recorded before, during and after
electroacupuncture (EA) at ST-36 (hind limb) or ST-25 (abdomen). EA at ST-36
significantly increased gastric motility and decreased the ratio of low
frequency (LF)/high frequency (HF) of the HRV analysis. In contrast, EA at ST-25
significantly inhibited gastric motility and increased LF/HF ratio. There was a
significant correlation observed between the changes of gastric motility and LF/HF
ratio in response to EA. It is suggested that the stimulatory effect of EA at
ST-36 on gastric motility is associated with its stimulatory effect on vagal
activity. The inhibitory effect of EA at ST-25 on gastric motility is associated
with its stimulatory effect on the sympathetic nerve activity.

OBJECTIVE: To approach to the best therapy for recovery of fingers function
after apoplexy. METHODS; One hundred and twenty-three cases were randomly
divided into an observation group of 63 cases and a control group of 60 cases.
The control group were treated by acupuncture at Quchi (LI 11), Shousanli ( LI
10), Waiguan (TE 5), etc., and the observation group by acupuncture at point "Xiajiquan"
besides the acupoints for the control group. After treatment of 10 sessions, the
therapeutic effects were assessed. RESULTS: The cured and markedly effective
rate was 74.6% in the observation group and 40.0% in the control group, the
observation group being significantly better than the control group (P < 0.05).
CONCLUSION: Point "Xiajiquan" has a better therapeutic effect on derivation of
finger muscular strength.

The Effects of
Rhizoma Curculiginis and Rhizoma Drynariae Extracts on Bones
Wong RW, Rabie B, Bendeus M, Hagg U.
ABSTRACT: BACKGROUND: Rhizoma Curculiginis (Xianmao) and Rhizoma Drynariae (Gusuibu)
are aYang-tonifyinga traditional Chinese herbal medicines used to strengthen
bones. This investigation aims to assess the systemic effect of extracts of
Rhizoma Curculiginis and Rhizoma Drynariae on bone histomorphology and
formation, and their local effect on bone healing. METHODS: For the
investigation of the systemic effect, thirty 8-week-old male BALB/c mice were
divided into three groups: (1) control group, ten mice fed daily with distilled
water; (2) Rhizoma Curculiginis group, ten mice fed daily with distilled water
mixed with Rhizoma Curculiginis extract; (3) Rhizoma Drynarie group, ten mice
fed daily with distilled water mixed with Rhizoma Drynarie extract. The mice
were fed for five weeks before sacrifice. Twenty micro-tomographic slices with
an increment of 0.25 mm were prepared to cover the proximal end of the left
tibia of each mouse. Quantitative morphometry of the bone structure was
performed. For the investigation of the local effect on bone healing, two bone
defects (5x10 mm) were created in the parietal bone of each of the three New
Zealand white rabbits. Two defects in the first animal were grafted with
collagen matrix with Rhizoma Curculiginis extract; two defects in the second
animal were grafted with collagen matrix with Rhizoma Drynarie extract; two
defects in the third (control) animal were grafted with collagen matrix alone.
The animals were sacrificed on day 14 and the defects were dissected and
prepared for histological and ultrastructural assessment. RESULTS: Rhizoma
Curculiginis and Rhizoma Drynariae extracts altered the bone histomorphology,
both increasing the trabecular number by 10% (P=0.002). Rhizoma Curculiginis
extract increased bone density by 3.13% (P=0.122) and Rhizoma Drynariae extract
increased bone density by 6.45% (P=0.005). Both Rhizoma Curculiginis and Rhizoma
Drynariae extracts induced new bone formation on the margins of the defects.
CONCLUSION: Two 'Yang-tonifyinga herbs, Rhizoma Curculiginis and Rhizoma
Drynariae, were demonstrated to have systemic effects on bone histomorphology
and formation as well as local bone healing.
