연구배경 : 결핵의 감염에서는 세포성면역이 중요하며 그 중에서도 T림프구가 중요한 역할을 하는 것으로 알려져 있고 조력 T림프구와 억제 T림프구의 기능의 불균형이 결핵의 발병에 있어 중요한 역할을 할 것으로 생각되고 있다. 동일한 결핵균의 감염시 일부 환자에서는 결핵의 병변이 폐에 국한되는 반면, 일부의 환자들에서는 폐의 결핵병변의 유무와 관계없이 폐외장기의 결핵이 발생되고 이러한 폐외결핵의 경우 항결핵화학요법에 잘 반응하지 않는 경우를 종종 경험할 수 있을뿐만 아니라 그 유병율의 감소도 폐결핵의 경우와는 달리 현저하지 못하여 폐결핵환자와 페외결핵환자군간의 면역기능의 차이가 의심된다. 방법 : 폐결핵환자와 폐외결핵환자군에서의 T림프구 매개성 세포성면역기능의 차이와 면역기능의 생체내검사와 생체외검사의 상관성을 규명하고자 T림프구 및 아형의 수적변화를 유세포분석법(flow cytometry)을 이용하여 측정하였고 PPD피부반응검사 및 림프아구형성을 측정하여 비교하였다. 결과 : 1) 총 림프구수는 결핵환자군에서 대조군에 비하여 유의하게 감소되어 있었으나 페결핵환자군과 폐외결핵환자군간의 차이는 없었다. 2) PPD 피부반응검사와 백혈구수는 3군간에 유의한 차이가 없었다. 3) $T_3$, $T_4$, $T_8$(+)인 세포의 백분율과 절대수는 3군간에 유의한 차이가 없었으며 $T_4/T_8$의 비도 3군간에 유의한 차이가 없었다. 4) HLA-DR(+)인 세포의 백분율과 절대수는 대조군에 비하여 결핵환자군에서 유의하게 증가되어 있었으며 $IL_2$ 수용체(+)인 세포의 백분율과 절대수도 결핵환자군에서 유의하게 증가되어 있었으나 폐결핵환자군과 폐외결핵환자군에는 유의한 차이가 없었다. 5) Concanavalin-A, Phytohemagglutinin 및 PPD 자극에 대한 림프아구형성은 3군간에 유의한 차이가 없었다. 6) $T_4$(+)인 림프구의 백분율 및 절대수와 PPD 피부반응검사의 크기사이에는 유의한 상관관계가 있었다. 결론 : 이상의 결과에서 폐결핵환자와 페외결핵환자군간에 T림프구성 매개성 세포성면역기능의 변화를 발견할 수 없었다. 그러나 본 연구만으로 세포성 면역기능의 차이를 모두 관찰하였다고 할 수는 없기 때문에 이에 대하여는 추후 연구가 필요하리라고 사료된다.

Over the last 50 years, a number of antibiotic agents have been developed and clinically used in the area of infectious diseases. Due to antimicrobial resistance problems and increasing health care costs, the rational use of antibiotics has been required. As a drug of choice to treat infections caused by MRSA, vancomycin has been extensively prescribed since the late 1970's. Recently, reports of vancomycin-resistant organisms such as VRE and VRSA have been increased to draw medical concerns. The objectives of this study were to evaluate the rational use of vancomycin and the appropriateness of the Restrictional Program of Antibiotic Utilization (RPAU) which has been operated at Samsung Medical Center. A retrospective chart review was performed in 132 hospitalized patients treated with vancomycin in the surgery departments from. January to June 1998. The guidelines of ASHP and HICPAC for vancomycin were modified and used as our criteria to determine the vancomycin DUE. In one hundred out of the patients, uses of vancomycin were approved by the Department of Infectious Diseases (DID) based on the RPAU. Vancomycin was appropriately used in $62.5\%$ of the 100 patients according to the criteria of justification of use, while $60.0\%,\;60.0\%,\;79.0\%,\;and\;51.0\%$ of the patients showed appropriate according to those of lab reports such as applicable culture obtained, pretreatment SCr, WBC and serum drug concentration monitoring, respectively. Although the rest 32 patients were not approved to receive vancomycin by the DID, twenty two percent continued receiving vancomycin treatment. This might result from the fact that the RPAU was started not before the use of antibiotics but in the middle of antimicrobial therapy. Continual education should be provide to the related health professionals and the RPAU should be simultaneously modified in order to increase the rate of appropriate uses of antibiotics.

The electrocardiogram of frogs were obtained in winter (January), spring (April), summer (July) and autumn (September and November). Electrocardiograms were recorded applying electrodes to the atria, ventricle and apex of the heart by unipolar or bipolar leads. V wave was recorded prior to P wave, for the presence of the sinus venosus which controls the automaticity of the frog heart, in four seasons. Regardless of the leads or the position of the electrodes P wave was diphasic and wide. According to the rise of temperature the rate of heart beat was increased, and V-P and P-R interval were shortened. Two regression line between R-R interval and both V-P interval and P-R interval were drawn. These were calculated as V-P interval=1 0.276R-R $interva1+0.067{\pm}0.15$ (sec.) and P-R interval=0.179R-R $interva1+0.155{\pm}0.1$ (sec). From these calculation the larger gradient of V-P interval than P-R interval was suggestive that the heart rate is more dependent on the changes of V-P interval than that of P-R interval. Changes of the heart rate were also measured in four seasons and artificial temperatures. Two regression lines between the heart rate (H.H.) and both seasonal temperature (T) and artificial temperature, were drawn. These two lines were calculated as H.R.=20+3.71 (T-10) and H.R.=32+1.425 T respectively. From two gradients of the above equations it is considered that the changes of the heart rate in artificial temperature were milder than that in seasonal temperature. The number of RBC and WBC of frogs were measured in four seasons and a tendency of the changes was observed according to the seasonal variation.

Objectives : The purpose of this study was to evaluate the significance of antibiotics in reducing postoperative infection rates and other complications following third molar surgery. Patients and methods : Two groups of patients underwent surgical extraction of third molars. The antibiotics group, n=21, received a third generation cephalosporin antibiotic for 5 days, starting from the day of surgery. The non-antibiotics group, n=26, didn't receive any antibiotics and only received analgesics to control postoperative pain. Body temperature and hematologic findings including WBC, neutrophils, lymphocytes and monocytes counts were compared between the two groups at three intervals, preoperatively, 24 hours and 7-10 days postoperatively. Pain and swelling during the follow up period were also recorded in both groups and compared in the second part of the study. Results : In the first part of the study, comparison of body temperature, CBC components (except WBCs) showed no significant difference between the two groups during the follow up period. All parameters were within the normal range at all intervals, which indicated absence of infection. In the second part, 38% of patients in the antibiotic group, compared to 54% of the non-antibiotics group, had one or more complications during the follow up period. However, three patients from the antibiotic group compared to one from the nonantibiotics group reported having a swelling of some degree. Conclusion : Based on our objective parameters (body temperature and CBC components), both groups showed no signs of infection during the follow up period. However, the results related to pain and swelling were less conclusive, probably due to small number of patients included in the study. Accordingly, we are unable to provide definite recommendations on antibiotics use in third molar surgery.

Failure Renal is the function of the kidneys to remove waste products and keep them on the periphery. and minerals for the body. Chronic renal failure is a syndrome characterized by a slow, irreversible deterioration of renal function due to the slow destruction of renal parenchyma. Calcium is one of the important minerals that the body contains in the blood and important tissues, and it has an important role in vital processes such as muscle contraction, nerve impulse conduction, the efficiency of heart muscle work, and blood clotting processes. The aim of the study is to study and compare calcium levels in men and women. It includes studying abnormal levels of calcium that cause many diseases, including chronic renal failure, and studying changes associated with renal failure. The method of this study was conducted on patients with chronic renal failure at Murjan Teaching Hospital in Babylon city during the period. The study included a sample of 70 patients (40 males, 30 females) with chronic renal failure, their ages ranged from 30-65, and 60 (30 males, 30 females) healthy without the disease of the same age. The result was a significant decrease in the number of red and white blood cells, hemoglobin concentration, hematocrit and platelets in patients with chronic renal failure, The result has been showed significant level in enzymes activity for transfer of amine group (alanine amino transferase, aspartate amino transferas) and phosphatase alkaline and also concentration of total bilirubin in patient with compare with healthy, Significantly increases, were found in the concentration of urea, uric acid and creatinine, as well as the concentration of calcium and phosphorous ions in the blood serum of patients compared to healthy controls.

A total of 109 heads of horses and ponies from eight horseback riding clubs nearby Central Taiwan were investigated to evaluate the blood parameters and the biochemical compositions of serum for the documentation of clinical pathological diagnosis and exercise physiology. Blood samples were collected from the jugular vein of resting horses. The sex difference in the blood traits were compared both in horses and in ponies. Results shows that total plasma proteins (PP) and hematocrit (PCV) were found higher in male horses than in females (p < 0.05). The sexual effect also exertes a significant influence on the leucocyte (WBC) count, but not on the erythrocyte (RBC) concentration. According to the differential counts of leucocytes, the number of monocytes and lymphocytes was higher in the male pony than that of in male horse. A close relationship Between the erythrocyte sedimention rate (ESR) and the other blood parameters were found especially in PCV, RBC concentration, and plasma protein level. The average ESR observed at 60 minutes were $21.80{\pm}21.87mm$, $39.50{\pm}18.90mm$ and $43.73{\pm}17.89mm$ in stallions, geldings, and mares, respectively. Most of the biochemical components of horse serum detected were distributed in normal ranges, although some of the items show a great variation in such a large sample size.

I selected the theory of blood stasis and wetness-phlegm among the major 4 causes of Joong Poong(C.V.A.)(wind. fire. deficiency of vital energy and wetness-phlegm) and recent etiology of blood stasis. An experimental studies were done to investigate the effects of Danggieum (removing blood stasis and promoting blood circulation) and Ijintang(dissipating wetness-phlegm) on thrombosis and elevated blood viscosity. The results were as follows; 1. The number of platelets were significantly increased in only Danggieum group. 2. Related to the amount of fibrinogen. only Danggieum group revealed some increase. but both groups revealed no significance. 3. Related to the prothrombin time. Danggieum and Ijintang groups had significant decrease. but Danggieum group revealed more significance. 4. Related to the degree of concentration of FDP, only Danggieum group had significant decrease. 5. Whole blood viscosity and plasma viscosity in lower shear rates. both groups of Danggieum and Ijintang had significant decrease. 6. Related to the amount of RBC. both groups of Danggieum and Ijintang had significant decrease. 7. Related to the change of hematocrit. only Danggieum group, and the change of hemoglobin. only Ijintang group had significant decrease. 8. Related to the change of body temperature. only Ijintang group had significant raise. 9. Related to the changes of WBC. glucose, albumin, total protein and body weight. Danggieum and Ijintang groups had each increase or decrease. but no significance. According to the above results, Danggieum had more significant effect than Ijintang on the thrombosis. and Ijintang had more significant effect than Danggieum on the elevated blood viscosity. And it is considered that it might be more effective in treating Joong-Poong(C.V.A) to take medicines regarding patient's constitution and symptoms as well as the causes of Joong-Poong(C.V.A)

The present study was devised to determine the effects of body weight, organ weight, hematological values and biochemical parameters by vitamin E and selenium (Selevit) on the Orch rats. The animals were divided into 4 groups. Intact group (n=10) received no treatment and operation. Sham group (n=10) received only sham operation and no treatment. Orch group received operation and no treatment. Orch+Selevit received operation and Selevit. The body weights of each group increased, but that of the Orch+Selevit group were significantly lower than those of all the other groups. There were significant differences (P<0.001) of body weights between Orch+Selevit group and all the other groups. Also, organ weights such as heart, liver, spleen and kidney were measured. The heart weights were significantly lower (P<0.001) in the Orch+Selevit group than in Intact and Sham group. The liver weights in the Orch+Selevit group were significantly differences (P<0.001) in comparison with those in the Intact and Sham groups. The kidney weights in the Orch+Selevit group were significantly differences (P<0.01, P<0.001) in comparison with those in all the other groups. On the other hand, there were no significantly differences in the organ weights of spleen between the Orch+Selevit groups and the any other groups. The number of white blood cell (WBC) was significantly higher (P<0.05) in the Orch+Selevit group than in all the other groups. The hematological values of red blood cell (RBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) were not significantly different in any of the groups. The concentrations of serum total protein, albumin and alkaline phosphatase increased significantly (P<0.05, P<0.01) in the Orch+Selevit group as compared to that in the Orch group. However, there were no significant differences in AST and ALT in any other groups. We conclude that Selevit was significantly decreased the body weight in the orchidectomized rats. Our findings suggest that Selevit may influence the process of lipid packaging and absorption in the orchidectomized rats.
