Seven cases of canine babesiasis were observed by clinically, hematologically and immunologically in the Kyungbook and Pusan area from May 1961 to October 1963. And a survey was conducted on the rising pups for their babesia, infection in the broken out districts of the disease. The results obtained were as follows: 1. Severe cases of canine babesiasis due to the same agent have been encountered in various breed, of dogs in widely separated location in the Kyungpook and Pusan area. 2. The principal symptoms oserved in infected dogs were severe anemia, weakness, inappetence, moderate fever or subnormal body temperature, increased respiration and pulse, palpitation, icterus, hemogrobinuria and redish yellow defecation. 3. Of hematological findings, decrease in erythrocytes count, hemoglobin content was evident and severe anemic changes occured which were associated with macrocytic anisocytosis. The differential leucocytes counts showed a tendency to increased monocytes and decreased monocytes and decreased basophil. 4. The principal anatomic chabges observed in two cases of infected dogs were severe anemic and icteric changes, markedly enlarged spleen, and enlarged liver with distended gall bladder. 5. Haemaphysalis bispinosa was suspected as being the principal vector of the infection. 6. It was suspected that chronic canine babesiasis would prevailed widely in Kyungpook and Pusan area, and that dogs are raised in such infected environment usually suffer only from the mild, chronic form, which may be practically symptomless, while imported dogs usually suffer from the acute form of the disease.

This study investigated the effects of temperature ($50^{\circ}C$, $55^{\circ}C$, and $60^{\circ}C$) and time (12 and 24 h) on the cookery properties of sous-vide (SV) processed pork loin. As an indicator of cookery properties, cooking loss, expressible moisture (EM), pH, differential scanning calorimetry (DSC), shear force, total plate count (TPC) and CIE color were measured and compared with fresh (FC) and cooked control (CC, $75^{\circ}C$ for 30 min). SV treatments at $50^{\circ}C$ showed higher tenderness and lower cooking loss comparing to CC. DSC result indicated that thermal transition of collagen was a key factor affecting the cooking loss and shear force of meat. In comparison of CC, risks of insufficient pasteurization and uncooked color generation were not shown in SV processed meat. Therefore, the results indicated that SV had a potential advantage to produce tender and moist meat, and the best SV condition of pork loin was estimated at $50^{\circ}C$ for 24 h.

To clarify the hematologic effects of the radioiodine ($^{131}I$) in therapeutic doses ($5{\sim}10$ mCi) on the various thyroid patients, authors studied the peripheral blood pictures of 396 goitrous patients before and after radioiodine ($^{131}I$) administrations in the Isotope Clinic of Seoul National University Hospital. Among these 396 cases of goiters, we gave 5 to 10 mCi of radioiodine ($^{131}I$) with single or fractionated administrations. The blood pictures of peripheral blood were repeated after 3 months in 40 cases of 65 cases who had been treated with $^{131}I$. The blood pictures of non-treated thyroid patients were compared with that of normal Korean values to clarify any difference between normal and goiter. The blood pictures of hyperthyroid patients treated with $^{131}I$ therapy were compared with the blood pictures of non-treated thyroid patients. The results were as following: 1) The incidence according to type: Toxic diffuse goiter: 35.4% Nontoxic nodular goiter: 29.7% Euthyroid: 13.8% Nontoxic diffuse goiter: 12.6% Hypothyroidism: 4.3% Thyroiditis($\bar{s}$ subacute form): 1.8% Toxic nodular goiter: 1.4% Malignancy: 1.0% 2) Age incidence: The range of distribution was 11 to 71 years. The peak incidence was found in the 4th decade of life. $80.6{\sim}82.6%$ of those 396 cases were found among the 3rd, 4th and the 5th decades of life. 3) Sex incidence: Sex ratio of male:female was 1:7.8. 4) The most outstanding findings in peripheral blood before treatment were decreased erythrocyte count and hemoglobin value in all types of thyroid diseases, especially in. the cases of hypothyroidism and thyroiditis. Hook worm-infested patients showed no significant difference in erythrocytes and hemoglobin values from those of other hook worm free patients. 5) Total leukocytes count was within normal range. Differential count of W.B.C. showed increased percentile of lymphocyte in diffuse toxic goiter and thyroiditis. 6) 39 cases of diffuse goiter treated with $^{131}I$ toxic showed amelioration in the anemia and restoration to normal range of lymphocyte count in association with increased percentile of neutrophiles 3 months after administration, except a case of toxic nodular goiter. One can observe anemia in slight degree, and increased lymphocytes count in hypothyroidism. Therapeutic dose of radioiodine ($^{131}I$) does not result any residual effect on the hematopoietic function. Radioiodine ($^{131}I$) therapy resulted in improvement of thyroid function in association of amelioration of pevious abnormal blood pictures. 7) Authors did not observe any myxedema resulted from radioiodine therapy during the 3 months period in this study.

Purpose: Mistletoe (Viscum album L.) extract is one of the most widely used agents in alternative cancer therapeutic regimens in Europe. This study was conducted to determine the effect of mistletoe extract on immune function in gastric cancer patients. Materials and Methods: Ten patients that had undergone a curative gastrectomy were enrolled in the prospective study. ABNOBAviscum $Q^{(R)}$ was injected subcutaneously three times a week from postoperative-day 7 to week 16 with an increasing dose. All of the patients simultaneously received chemotheraphy with mitomycin, oral 5-FU and a cisplatin regimen. The WBC count, differential count, lymphocyte/WBC ratio and the level of cytokines (IL-$1{\beta}$, IL-2, IL-6, IFN-$\gamma$, TNF-$\alpha$) were checked in the peripheral blood preoperatively, at postoperative week 8 and at postoperative week 16. Results: The WBC and neutrophil counts significantly decreased after treatment on week 8 and week 16 (P=0.001), but the total eosinophil count was slightly increased (P=0.15). The total lymphocyte count also decreased during treatment but the lymphocyte/WBC ratio was slightly increased without statistical significance (P=0.91). The cytokine levels did not significantly change during treatment. Conclusion: It is somewhat difficult to determine the direct effect of mistletoe therapy on immune function as the effect may be compromised by the concurrent chemotherapy. It can be assumed that the slightly increased lymphocyte/WBC ratio and eosinophil count may be a result of the immunomodulatory effect of the mistletoe extract.

Purpose : Radiation-induced alteration in the immune function is well known phenomenon in cancer patients. Our purpose is to evaluate the extent of immune suppression immediately after mediastinal or pelvic irradiation, which include significant volume of active bone marrow in adults. Materials and Methods'48 cancer patients with mediastinal(N=29) and pelvic irradiation(N=19) were the basis of this analysis. Age ranged from 36 to 76 and mean and median value was 57 years, respectively Sex ratio was 1.3(M: F=27/21). The immunological parameters were the complete blood cell(CBC) with differential cell(D/C) count, T cell subset(CD3, CD4, CD8 CDl9), NK cell test(CDl6, CD56), and serum immunoglobulin(IgG, IgA, IgM) level. Results : The mean value of white blood cell(WBC) was reduced from 7017 to 4470 after irradiation(p=0.0000). In the differential count, the number of lymphocyte, neutrophil, and basophil was markedly reduced with statistical significance(p<0.01) and the number of monocyte was not changed and, on the contrary, that of eosinophil was increased by irradiation. In the lymphocyte subpopulation analysis, the number of all subpopulations, CD3(T cell), CD4(helper T cell), CD8(suppressor T cell), CDl6(NK cell), CDl9(B, cell) was reduced with statistical significance. The mean ratio of CD4 to CD8 in all patients was 1.09 initially and reduced to 0.99 after radiotherapy(p=0.34) , but the proportional percentage of all subpopulations was not changed except CD19(B cell) after irradiation. In the immunoglobulin study, initial values of Ig G, Ig A, and Ig M were relatively above the normal range and the only Ig M was statistically significantly reduced after radiotherapy(p=0.02). Conclusion : Mediastinal and pelvic irradiation resulted in remarkable suppression of lymphocyte count in contrast to the relatively good preservation of other components of white blood cells. But the further study on the functional changes of lymphocyte after radiotherapy may be necessary to conclude the effects of the radiation on the immunity of the cancer Patients.

The importance of genetic resource preservation has been highlighted in the literature as a means of maintaining genetic diversity. Investigations for hematologic values and the differential count of white blood cell count (WBC) for Korean indigenous cattle (KIC) and endangered indigenous cattle (EIC) are rarely performed. Therefore, the objective of this study was to investigate the hematologic values of total 40 EIC (White, Black, Mini cattle) and 35 KIC as control by analysis of hematologic characteristics. As a result, the mean values of RBC and platelet of EIC were significantly decreased by age (p<0.05). The mean values of RBC, HCT, MCV and MCHC between EIC and KIC of the same age (2~3 years) showed the statistical significance (p<0.05). Also, in the WBC of EIC, the mean values were decreased according to the age from $13.9{\times}10^3/{\mu}L{\sim}12.7{\times}10^3/{\mu}L$ under 1 year to $9.1{\times}10^3/{\mu}L{\sim}11.5{\times}10^3/{\mu}L$ over 2 years respectively. In the differential count of WBC of EIC (White, Black, Mini cattle), it showed generally the rates of 40.2%, 52.2%, 49.0% lymphocyte and 27.2%, 33.9%, 32.0% segmented neutrophil from 2~3 years respectively. Result of this study will be used for establishing reference range for blood analysis in EIC such as white, black and mini cattle. This study reported hematological values which could serve as baseline information for comparison in conditions of nutrient deficiency, physiological and health status of endangered Korean native cattle. In addition, this study provides a valuable resource for further investigations of the preservation of rare genetic stocks underlying traits of interest in cattle.

Background : Differential diagnosis of lymphocytic pleural effusion is difficult even with many laboratory findings. Nitric oxide(NO) level is higher in the sputum or exhaled breath of patients with active pulmonary tuberculosis than in those without tuberculosis. In addition, there are some reports about the increased level of NO metabolites in body fluids of cancer patients. However, there is no data on the NO levels in the pleural fluid of patients with tuberculous pleurisy. Method : The serum and pleural fluid NO in the patients with acute lymphocytic pleural effusion were analyzed. Results : Of total 27 patients, there were 14 males and average age of patients was 48 years. The final diagnosis was tuberculous pleurisy in 17 cases and malignant pleural effusion in 10. The pleural fluid NO level was $540.1{\pm}116.4{\mu}mol$ in the tuberculous pleurisy patients and $383.7{\pm}71.0{\mu}mol$ in the malignant pleural effusion patients. The serum NO level was $624.7{\pm}142.0{\mu}mol$ in tuberculous pleurisy patients and $394.4{\pm}90.4{\mu}mol$ in malignant pleural effusion patients. There was no significant difference in the serum and pleural fluid NO level between the two groups. The NO level in the pleural fluid showed a significant correlations with the pleural fluid neutrophil count, the pleural fluid/serum protein ratio, and pleural fluid/serum albumin ratio (p<0.05 in each). The protein concentration, leukocyte and lymphocyte count in the pleural fluid were significantly higher in the tuberculous pleurisy patients than the malignant pleural effusion patients (p<0.05 in each). Conclusion : NO is not a suitable marker for a differential diagnosis of lymphocytic pleural effusion. However, the NO level in the pleural fluid might be associated with the neutrophil recruitment and protein leakage in the pleural space.

Background: It is sometimes difficult to differentiate tuberculous pleural effusion from malignant pleural effusion by clinical symptoms, signs, by routine tests of pleural fluid, and by pathologic studies. And recently, it was discovered that cytokines such as IL-2, IFN-$\gamma$, TNF-$\alpha$ are elevated in tuberculous pleural fluid, and there have been several attempts to diagnose tuberculous pleural effusion by using these immunological mediators. There are several studies regarding the diagnostic value of IFN-$\gamma$, and there are two studies in Korea. But the diagnostic values of IFN-$\gamma$ in these studies were slightly lower than those in other countries. To compare the diagnostic value of IFN-$\gamma$ with those of CEA and ADA, and to determine the sensitivity and specificity of IFN-$\gamma$ in Korean, we mesured IFN-$\gamma$, CEA level and ADA activity in pleural effusions. Methods: ADA activity, IFN-$\gamma$ level and CEA level as well as cell count, differential count, and biochemical assays such as protein content and lactate dehydrogenase were measured in 40 cases of tuberculous pleuritis and 42 cases of malignant pleural effusion. Results: Tuberculous pleural fluid showed higher levels of IFN-$\gamma$ and ADA ($832.6{\pm}357.2$ pg/ml and $82.5{\pm}25.9$ U/L, respectively) than those of malignant pleural effusion ($2.6{\pm}8.0$ pg/ml and $19.2{\pm}10.9$ U/L, respectively) (p<0.01). Malignant pleural effusions showed higher median value (102.2 ng/ml) than tubercalous pleural effusions (1.8 ng/ml) (p<0.01). The sensitivities of IFN-$\gamma$, ADA, CEA were 0.97, 0.87, 0.67 and the specificities of IFN-$\gamma$, ADA, CEA were 1.0, 0.97, 1.0, respectively. There was no significant correlation between ADA activity and IFN-$\gamma$ level. Conclusion: This study showed that IFN-$\gamma$ test would be a very useful clinical test for differential diagnosis of tuberculous pleuritis and malignant pleural effusion because it is very sensitive and specific, although it is an expensive test.

Theileria sergenti were isolated from infected erythrocytes by hypotonic Iysis, and soluble meroBoite antigens were purified by sonication and differential centrifugation. The preparation contained 29, 34, 35 and 105 kD immuno-dominant polypeptides. The soluble antigens (0.5 mg/ml) were prepared and fortified with Freund's adjuvant. Five month old naive Korean calves were subcutaneously inoculated with the preparation and a booster dose was administered 4 weeks later Nine weeks after the booster dose, vaccinates and controls were challenged with a homologous stabilate (5.6×106 RBC/dose, 40% Parasitemia). All animals were monitored for hematocrit, total erythrocyte count, parasitemia and for the specific antibody by Western immuno- blot (WB) and indirect immuno-auorescent antibody(IFA) test. By 18 weeks after vaccination (6 weeks after the challenge), vaccinated cattle had an average IFA titer of 1 : 10,240 compared with 1 : 1,280 of the controls. The vaccinates showed ne91igib1e change in hematocrit and total RBC count whereas control animals showed significant (P<0.05) hematological chanties and associated anemia. After vaccination and challenge, the antibody responses demonstrated that vaccination had induced significant production of antibody to the 29 and 35 kD polypeptides. The latter polypeptide was much more strongly recognized by the vaccinated animals, and thus it may be a potential candidate for the vaccine.

This study was carried out to investigate the effects of activated carbon (AC) on growth, ruminal charateristics, blood profiles and feed digestibility in sheep, using roughage-based or concentrate-based diets. Twelve Suffolk breed of sheep of similar age and weight were distributed into 4 groups in a $2{\times}2$ factorial design. Two groups were fed a roughage-based diet with (R + AC) and without AC (R - AC), while the other two were fed a concentrate-based diet with (C + AC) and without AC (C - AC), respectively. The addition of 0.3% AC was based on dry matter of feed offered to animals. The incorporation of AC in roughage and concentrate based diets had no marked effects on feed intake, daily gain and feed conversion of the animals within experimental diets. The results obtained might be due to the low level of AC added in the diet. The animal on both concentrate-based diets were higher than the roughage-based diets in terms of daily gain and feed conversion ratio. However, it was observed that the animals provided with AC in the concentrate-based diet did not suffer from diarrhea and easily adjusted to high concentrate feeding. Further, the pH value for all diets before feeding was noted to be similar. After feeding, however, pH was shown to be higher in R + AC (p < 0.05) than in C + AC diet. Rumen protozoa number was decreased after feeding for both + AC diets, but in C - AC diet it was higher than in the roughage-based diets. For ammonia-nitrogen, C - AC was found to be higher than C + AC diet and the roughage-based diets before feeding. Total volatile fatty acid concentration, propionate and valerate molar ratios for both diets and time of collection were not affected. However, acetate, butyrate and valerate molar ratios were observed to be affected by diets and time of collections. The diets with AC increased (p < 0.05) before feeding for acetate molar ratio, but not different within diet, however, the roughage diets were found to be higher (p < 0.05) in acetate than the concentrate diet. In the blood parameters, the glutamic pyruvic transaminase (GPT), red and white blood cell (RBC, WBC) counts and packed cell volume (PCV) did not differ within and among the diets. Likewise, the WBC differential count in both diets with either - AC or + AC were similar in trend. However, lymphocyte count was noted to be increased in R + AC than the R - AC diet. The addition of AC in both diets did not affect nutrient digestibilities within diets.
