Producer prices of raw milk include following elements: a basic price, payment according to fat content, payment according to bacteriological quality and somatic cell count. The quality of raw milk has increased since last change of payment system according somatic cell count. But last change of payment system according to fat content is not effective. It is necessary to widen the range of equal price by fat content. Also it is necessary to include payment according to protein content.

In order to investigate the effects of Sakunjatang(四君子湯) and Samultang(四物湯) aqua-acupuncture on immune response, Sprague-Dawley male rats were used and randomly divided into four group. Normal group was normal control, Control group was injected i.v. with 2mg/kg MTX on 9th and 11th day after sensitization with SRBC on 5th day, Sakunjatang aqua-acupunctured group(Sample A) was aqua-acupunctured daily for 18 days into the locus corresponding Bisu(B20) locus of the human body to Rat and MTX was administered 9th and 11th experimental day, Samultang aqua-acupunctured group(Sample B) was aqua-acupunctured daily for 18 days into the locus coresponding Bisu(B20) locus of the human body to Rat and MTX was administered 9th and 11th experimental day. In the 9th day and the 11th day after aqua-acupuncture, MTX was injected to reduce immune function in the tail of rat. leukocyte count, lymphocyte ratio, lymphocyte count of spleen, lymphocyte count of bonemarrow, contact hypersensitivity to DNFB, morphologic change of thymus cell, and electropherogram of serum protein. The result were summarized as follows: 1. Before MTX injection, leukocyte count had no significant difference in Sakunjatang aqua-acupunctured group and Samultang aqua-acupunctured group compared to control group and after MTX injection, leukocyte count had no significant difference Sakunjatang aqua-acupunctured group and Samultang aqua-acupunctured group. 2. Before MTX injection, lymphocyte ratio was decreased significantly Sakunjatang aqua-acupunctured group and Samultang aqua-acupunctured group compared to control group. 3. After MTX injection, lymphocyte ratio was increased significantly Sakunjatang aqua-acupunctured group, Samultang aqua-acupunctured group had no significant difference compared to control group. 4. The lymphocyte count of spleen was increased significantly Sakunjatang aqua-acupunctured group and Samultang aqua-acupunctured group compared to control group. 5. The lymphocyte count of bonemarrow was increased significantly Sakunjatang aqua-acupunctured group, Samultang aqua-acupunctured group had no significant difference compared to control group. 6. Contact hypersensitivity was no significant difference in Sakunjatang aqua-acupunctured group and Samultang aqua-acupunctured group compared to control group. 7. In the morphologic change of thymus cell, control group compared to normal group had a indistinct boundary between cortex and medulla, and lymphocyte cell density of thymus was low, Sakunjatang aqua-acupuryctured group had a distinct boundary between cortex and medulla, and lymphocyte cell density of thymus was high. 8.

배경: 동맥경화가 일종의 염증성 반응에 의해 매개된다는 이론을 바탕으로 여러 연구에서 백혈구 수치의 증가가 심혈관 질환에 의한 사망에 영향을 준다는 결과가 보고되고 있다. 같은 맥락에서 관상동맥우회술 시에도 수술 전 백혈구 수치가 수술 후 사망의 독립예측변수라는 보고들이 있다. 저자들은 본 연구를 통해 관상동맥우회술시 수술 전 백혈구 수치가 수술 후 사망 및 합병증 발생에 있어 과연 어떤 영향을 미치는가를 알아보고자 하였다. 대상 및 방법 : 1996년부터 2003년까지 인하대병원 흉부외과에서 단독 관상동맥우회술(isolated coronary artery bypass grafting)을 시행한 환자 133명을 대상으로 의무 기록의 후향적 분석을 시행하였다. 수술 전 백혈구 수에 따라 환자들을 오름차순으로 배열한 후 균등하게 A, B, C, D군의 네 군으로 나누었을 때 수술 전 백혈구 수치의 범위는 A군은 $1.3\times10^3/{\mu}L$에서 $5.9\times10^3/{\mu}L$까지, B군은 $6.0\times10^3/{\mu}L$에서 $7.0\times10^3/{\mu}L$까지 C군은 $7.1\times10^3/{\mu}L$에서 $8.9\times10^3/{\mu}L$까지 D군은 $8.9\times10^3/{\mu}L$에서 $16.9\times10^3/{\mu}L$까지로 환자 수는 A군만 34명을 포함시켰으며 나머지 군은 모두 33명으로 동일하였다. 결과: 수술 전 심근경색이 선행된 환자 수는 A군에서는 0명, B군 2명$(6.1\%)$, C군 4명$(12.1\%)$, D군 8명$(24.3\%)$으로 백혈구 수가 높은 군일수록 심근경색이 선행된 환자 수가 많음이 입증되었다(p<0.01). 수술 후 사망 예는 모두 6예로, A군 1명$(2.9\%)$, B군 1명$(3.0\%)$, C군 2명$(6.1\%)$, D군 2명$(6.1\%)$으로 각 군에 따른 유의한 차이는 보이지 아니하였다(p=0.44). 수술 후 창상 감염은 3명의 환자에서 발생하였는데 3명 모두 D군에서 발생하였다. 결론: 관상동맥우회술 환자에서 수술 전 백혈구 수치와 술 후 사망간의 연관 관계는 찾을 수 없었다. 술 전 백혈구 수치가 높은 군에서 술 후 창상 감염의 빈도가 증가하였다.

Toxoplasmosis, a neglected tropical disease caused by the protozoan parasite Toxoplasma gondii, occurs throughout the world. Human T. gondii infection is asymptomatic in 80% of the population; however, the infection is life-threatening and causes substantial neurologic damage in immunocompromised patients such as HIV-infected persons. The major purpose of this study was to investigate the seroprevalence of T. gondii infection in subjects infected with HIV/AIDS in eastern China. Our findings showed 9.7% prevalence of anti-T. gondii IgG antibody in HIV/AIDS patients, which was higher than in intravenous drug users (2.2%) and healthy controls (4.7%), while no significant difference was observed in the seroprevalence of anti-Toxoplasma IgM antibody among all participants (P>0.05). Among all HIV/AIDS patients, 15 men (7.7%) and 10 women (15.9%) were positive for anti-T. gondii IgG antibody; however, no significant difference was detected in the seroprevalence of anti-Toxoplasma IgG antibody between males and females. The frequency of anti-Toxoplasma IgG antibody was 8.0%, 13.2%, 5.5%, and 0% in patients with normal immune function ($CD4^+$ T-lymphocyte count ${\geq}500cells/ml$), immunocompromised patients (cell count ${\geq}200$ and <500 cells/ml), severely immunocompromised patients (cell count ${\geq}50$ and <200 cells/ml), and advanced AIDS patients, respectively (cell count <50 cells/ml), while only 3 immunocompromised patients were positive for anti-T. gondii IgM antibody. The results indicate a high seroprevalence of T. gondii infection in HIV/AIDS patients in eastern China, and a preventive therapy for toxoplasmosis may be given to HIV/AIDS patients based on $CD4^+$ T lymphocyte count.

A comparative study between 17 Japanese and 19 Indian patients with oral squamous cell carcinomas (OSCCs) revealed that the tumour prognostic indicator mean vessel density (MVD) count for angiogenesis was relatively high at 57.1 in Indian as compared to 39.3 in Japanese (P=0.001) cases, whereas the lymph-vessel density (LVD) count for lymphangiogenesis was lower (12.8 vs 48.0, P=0.002). Both male and female Indians had higher MVD counts, but LVD counts were only slightly lower in females. MVD count was relatively high among the cases below 65 years old in both the countries (P=0.4). Japanese cases with Tongue cancer had higher MVD count, but the Indian cases had lower LVD counts. Size-wise, T2 and T3 had higher counts of MVD both in Indian and Japanese cases. MVD and LVD count was higher in grades II and III both in Japanese and Indian cases. There was insignificant difference of the MVD counts among smokers, but the tobacco chewers in Indian cases had higher counts of MVD and LVD (P value by Bartlett test 0.35, 0.57 respectively). The hot-spots of tumour sites had variable rates of lymphocyte infiltration showed higher MVD counts in all the cases. Although the clinical characteristics and demographic variables usually relate to MVD and LVD counts, the tendency of higher values, especially among tobacco chewers, identified as the highest risk group for occurrence of oral cancer needs to be investigated further.

Objectives : The purpose of this study was to investigate the effects of modified fasting therapy on body composition, blood cell count and blood chemistry in inpatients. Methods : The modified fasting therapy program consists of three phases, a period of reducing food intakes, fasting and refeeding. Body weight, body composition, and the degree of obesity were estimated in before fasting therapy and after refeeding. Blood cell count and blood chemistry were estimated in before fasting therapy, before refeeding and after refeeding. Results : After modified fasting therapy, body weight, body fat mass, percent body fat, body mass index(BMI), body matabolic rate(BMR) and muscle mass was decreased significantly. WBC count and platelet count decreased significantly, RBC count and hemoglobin increased significantly and hematocrit was not changed significantly but within normal limit. AST and ALT increased significantly, especially patients group over BMI 25 within normal liver function. This study was not founded correlation between decreased muscle mass and increased liver function test. ALP, BUN, Total-cholesterol, and triglyceride decreased significantly. Creatinine increased significantly, but within normal limit. Sodium was not changed significantly, potassium decreased significantly but within normal limit. Conclusions : These results suggest that modified fasting therapy will be beneficial if several measures complement.

In recent years, many researches are actively undertaken for environmental-friendly animal production according to the increased understanding about food safety because of the outbreak of various diseases such as mad cow disease, Foot and mouth disease and Poultry Influenza virus. However, high quality(higher safety)- animal production may not be successful without increasing of disease resistance of animal and the improvement of feeding environment. To increase the disease resistance is able to be accomplished by stimulating the immune function. The present study was undertaken to investigate the effects of enzyme mixture reinforced with ${\beta}$-glucanase activity which degrade polysaccharide to release ${\beta}$-glucan known as stimulator of immune function on the change of milk production and somatic cell count. After 12weeks of experimental feeding, milk production tended to be increased and somatic cell count was decreased from average $227{\times}10^4$ to $37.1{\times}10^4$. Milk protein and solid-fat content were tended to increase but milk fat showed decreasing tendency by the feeding of enzyme mixture. All together, it has been suggest6d that the improvement of high quality milk production may be possible through the dietary addition of immune modulating enzyme mixture in lactating dairy cows.
