Objective: This study addressed a case of central post-stroke pain described as right arm painful with coldness and left lateral medullary infarction. Methods: A patient, 71 years old female with medullary infarction, was treated with a Korean herbal medication (BackJun-pill). The improvement of symptoms was evaluated using the Numeral Rating Scale and reports of coldness and pain in the affected areas. We also measured the body temperature difference between the left and right arms using digital infrared thermographic imaging (DITI). Results: After six weeks of treatment with Korean medicine, the patient's pain and sensation of coldness decreased. Conclusions: This clinical case study suggests that BackJun-pill may be effective for alleviating pain and coldness due to central post-stroke pain.

BacJung-pil(百中丸) using in stagnation-syndrome of gi and blood(痺證) is a expience prescription, A female patient diagnosed as wind syndrome of head(頭風), and stagnation-syndrome of gi and blood(痺證) showed severe pruritus, rash and eruption of skin. After the patient took BackJun-Pill, two hours later, We examined her change and witnessed macular papule and severe pruritus. Those symptoms disappeared in 7 days since we administer anti-histamine, steroid and GamDu-TangGamiBang(甘豆湯加味方).

This paper proposes a method to improve the left right discrimination performance by eliminating the imaginary target based on the frequency features of the beam pattern for bow array. The beamwidth of the imaginary target is wider than that of the real target. If an azimuth axis is considered as a time axis, the real and the imaginary targets can be assumed as high and low frequencies, respectively. To eliminate the imaginary target which has a low frequency component, we design a cut-off frequency of the High Pass Filter (HPF) using the back-lobe imaginary beamwidth. The real target is estimated by eliminating the imaginary target by applying HPF to the entire power of the beamformer output. Computer simulations show that the proposed method can increase the left right discrimination performance above 8 dB on average.
