  • During heat treatment and storage of milk, deteriorative reaction takes place, which consequently influence on the milk quality. In this study, formation of lactulose and furosine under different thermal conditions and storage conditions, and the ratio of lactulose and furosine (LU/FU) in presence of reconstituted milk powder were determined to establish chemical indicators for heat damages of milk and the adulteration of fresh milk in dairy field. The lactulose and furosine contents linearly increased with increased heating temperature and heating time. It showed high correlation between the formation of lactulose and furosine, and the treatment temperature and time (p<0.05). The lactulose and furosine concentration of HTST milk and UHT milk noticeably increased during storage at $30^{\circ}C$, but there was no noticeable increase of lactulose and furosine concentration at lower storage temperature. In the raw milk, the lactulose and furosine contents greatly increased with the addition of reconstituted milk. The increase level of furosine was much higher than that of lactulose, which consequently resulted in the lower LU/FU ratio in milk as increase of added reconstituted milk amounts. As comparing with raw milk, there was more than twice reduction in LU/FU ratios after the addition of reconstituted milk (p<0.05). It can be concluded that lactulose and furosine are suitable milk quality indicators of heat damage and for demonstrating improper addition of reconstituted milk powder.

  • Purpose : To assess the feasibility and the toxicity of the neoadjuvant chemotherapy on the treatment of patients with locoregionally advanced nasopharyngeal carcinoma. Methods and Materials : We analyzed 77 previously untreated and histologically confirmed advanced stage nasopharyngeal carcinoma patients treated with neoadjuvant chemotherapy followed by radiation therapy at the Seoul National University Hospital between 1984 and 1996. The stage distribution was as follows : AJCC stage III-2, stage IV-75. Sixty-six patients received infusion of 5-FU (1000 mg/m$^2$, on Day 1$\~$5) and cisplatin (100 mg/m$^2$, on Day 1), eleven patients received infusion of 5-FU (1000 mg/m$^2$, on Day 1 $\~$5) and carboplatin (300 mg/m$^2$, on Day 1) as neoadjuvant chemotherapy Prior to radiation therapy. The median follow-up for surviving patients was 44 months. Results : The overall chemotherapy response rates were 87$\%$. The toxicities of chemotherapy were mild. Only 3 patients experienced Grade 3 toxicities (1 for cytopenia, 2 for nause/vomiting). The degree of radiation induced mucositis was not severe, and ten patients developed Grade 2 mucositis. The 5-year overall survival rates were 68$\%$ and the 5-year disease free survival rates were 65$\%$. The 5-year freedom from distant metastasis rates were 82$\%$ and 5-year locoregional control rates were 75$\%$. Conclusion : This single institution experience suggests that neoadjuvant chemotherapy improves overall survival and disease free survival for patients with advanced stage nasopharyngeal carcinoma without increase of toxicity.

  • Objective: This study reports the effect of Hyungbangjihwang-tang-gami as a treatment for Soyang-in patients with chronic diarrhea. Methods: We treated three male patients with chronic diarrhea who did not improve after taking herbal medicine, as determined by zang-fu (organ) pattern diagnosis. After changing our approach to a Sasang constitution, we prescribed Hyungbangjihwang-tang-gami and assessed the effect by the frequency or form of defecation. Results: The patients' complaints worsened when they were administered a herbal medicine unsuited to their Soyang constitutions, which caused an exuberance of Yang. Changing the herbal medicine to Hyungbangjihwang-tang-gami improved their symptoms. Conclusions: This study suggested that Soyang-in patients may have side effects when administered unsuitable herbs, even if they were diagnosed using zang-fu (organ) pattern diagnosis. When we treat patients, we have to consider their Sasang constitution, as well as the zang-fu (organ) pattern diagnosis.

  • 뇌모세혈관내피세포로 구성된 혈액-뇌관문(BBB)은 tight junction으로 구성되어 있을뿐만 아니라 fenestra가 없는 등 BBB가 가진 특성으로 인해 물질 수송에 장벽역할을 하기 때문에 주로 중추신경계 질환시의 약물요법에 많은 제한이 따른다. 따라서 뇌로의 효율적인 약물 송달방법에 대해 많은 연구가 진행중에 있는데 본 연구에서는 BBB의 hyperosmotic opening법을 이용하여 뇌로 잘 수송되지 않는 약물의 뇌송달 방법에 대해 연구하고자 하였다. 먼저 수용성으로 인해 BBB 에 잘 통과하지 않는 물질로 신장 및 뇌영상 촬영시 사용되는 방사성 의약품이 Tc-DTPA를 이용하여, hyperosmotic opening법에 의한 뇌투과 증가정도를 검토하였으며, 실험방법이 확립됨에 따라 뇌암의 항암요법을 위해 뇌로의 투과가 적은 항암제(5-Fluorouracil, 5-FU)의 뇌송달에 대해 본 방법을 적용하여 검토하였다. 실험동물로는 S.D.계 웅성 랫트를 사용하였으며, 실험방법은 다음과 같이 하였다. 랫트의 좌측 외경동맥(left external carotid artery)에 혈류의 역방향으로 혈관 분지점에서 1-2mm 전까지 PE-50 catheter를 삽입하고, 1.6 molal L-(+)- arabinose 고장액(1580mOsm)을 0.12ml/sec의 일정한 속도로 30초간 infusion함으로 BBB를 opening 한 다음, 5분 후에 Tc-DTPA를 대퇴 정맥으로 주사하여 0, 10, 30초, 1, 1.5, 2, 3, 4, 5, 7 및 10분 간격으로 대퇴동맥에 설치한 카테타로부터 혈액을 채취하고 마지막 혈액을 취한 후 즉시 단두하여 뇌를 적출하였다. 채취한 뇌를 액체질소에 담근 후 tissue Tek으로 고정하고 autoradiography를 하기 위한 slice와 농도측정을 위해 필요한 부위를 취한 후 감마카운터로 Tc-DTPA의 brain각 부위별 및 혈장농도를 측정하였다. 뇌조직중 혈액부피의 측정은 Tc-albumin를 이용하여 구하였다. 같은 방법으로 5-FU에 대한 실험도 행하였고, 이때 각 혈장 및 조직중의 5-FU함량은 HPLC로 하였다.

  • Objectives : The purpose of this paper is to examine the mechanism and treatment of the Zangfu warm disease in the Beijiqianjinyaofang. Methods : This study examined the Zangfu warm disease content in the Beijiqianjinyaofang, Shanghanzongbinglun, Saninfang, based on the Neijing explanation of the pathological mechanism. Treatment was analyzed among the three texts in terms of their similarity and difference. Results & Conclusions : 1. Zangfu warm disease is caused by seasonally inappropriate qi, which is infectious, epidemic, and seasonal. 2. While the Qingjinqian disease pattern was explained in terms of the relationship between Shaoyin and Shaoyang, the actual disease pattern happened more in the Taiyang channel, and partly in the Shaoyang channel. For treatment of Fu deficiency pattern, the Chaihudihuangtang was listed in the Qianjinyaofang and the Shanghanzongbinglun, while in the Sanyinfang, the formula was modified to extinguish heat and thin phlegm, while reinforcing healthy qi. 3. The Chimaifei disease pattern was explained in terms of the relationship between Shaoyin and Taiyang that is deeply associated with Wei qi. For treatment of Fu deficiency the Qianjinyaofang and Shanghanzongbinglun used the Shigaodihuangtang, while the Sanyinfang reinforced healthy qi and eliminated pathogenic qi. 4. The Huangrousui disease pattern was explained as being caused by problems in the Taiyin and Yangming, in which the Triple Burner fails to control and manage cold dampness. In treating Zang excessiveness, the Qianjinyaofang and Shanghanzongbinglun used the Xuanshenhanshuishitang, while the Sanyinfang instructed to reinforce healthy qi and eliminate pathogenic qi. In treating Fu deficiency, the Sanyinfang instructed to warm the center and dry dampness, tonifying the Spleen and reinforcing qi. 5. The Baiqili disease pattern was explained within the relationship between Taiyin and Taiyang. In treating Fu deficiency, the Qianjinyaofang and Shanghanzongbinglun used the Shigaoxingrentang, while the Sanyinfang instructed to reinforce healthy qi and eliminate pathogenic qi. In treating Zang excessiveness, the Qianjinyaofang and Shanghanzongbinglun used the Shigaocongbaitang, while the Sanyinfang instructed to reinforce healthy qi and eliminate pathogenic qi. 6. The Heiguwen disease pattern was explained as being caused by stagnation and obstruction in the Triple Burner due to clash between Taiyang and Shaoyin. In treating Zang excessiveness, the Qianjinyaofang and Shanghanzongbinglun used the Kushenshigaotang, while the Sanyinfang instructed to reinforce healthy qi and eliminate pathogenic qi. The Zangfu Warm Disease is a infectious disease concept which is based on the Five Zang that integrates the meridian aspect together with the Six Fu with which there is an external/internal relationship. This concept and treatment could be considered in dealing with COVID-19.
