Bovine drumstick of neutrophil leucocytes was studied on the quantitative and morphological characteristics and was evaluated as a diagnostic measure for bovine freemartin in newborn calves. Nuclear area of neutrophil (A, ${\mu}m^2$) and drumstick area (B, ${\mu}m^2$) were significantly correlated with average diameter of drumstick (ADD, ${\mu}m$) and following regression equations were obtained : $A=45({\pm}3)$ ADD-8, r = 0.74, $s.e.{\pm}0.6$, p < 0.01, $B=1.72({\pm}0.05)$ ADD-0.98, r = 0.93, $s.e.{\pm}0.1$, p < 0.01 Eight female siblings of heterosexual multiplets were diagnosed as freemartin from the results of chromosome analysis. Heterosexual multiplets had a very low frequency of drumstick in the nucleus of neutrophils irrespective of genetic sex. Diameters of drumstick fund in freemartin and male cotwin did not differ from those of normal cows. Examinations of drumstick in 800 neutrophils for both female and male siblings are concluded to be the best way to aid the detection of freemartinism of heterosexual twins at early life.

Proinflammatory effects of bacterial lipopolysaccharide (LPS) have been assessed by analysing the induction of two inflammatory genes, $interleukin-1\beta$ $(IL-1\beta)$ and cyclooxygenase-2 (COX-2), in rainbow trout (Oncorhynchus mykiss) macrophage cells. Production of a metabolite of arachidonic acid by COX-2, prostaglandin $E_2\;(PGE_2)$, was also analysed in macrophage cells after LPS stimulation. Northern blot analysis revealed that LPS $(5{\mu}g/mL)$ significantly upregulated $IL-1\beta$ (54 times) and COX-2 (40.7 times) gene expression in macrophage cells after 4 h stimulation. According to RT-PCR (Reverse Transcription Polymerase Chain Reaction) analysis, $IL-1\beta$ gene induction in LPS stimulated macrophage cells was started within 1h and significantly increased thereafter until 4h. Meanwhile, COX-2 gene induction by LPS was delayed in comparison with $IL-1\beta$ gene induction as a faint band was observed after 4h stimulation in head kidney macrophage cells. LPS also significantly increased $PGE_2$ production in head kidney leucocytes, presumably via activating COX-2 expression that metabolites arachidonic acid to $PGE_2$. In conclusion, it was demonstrated that LPS could induce two main inflammatory and immune related genes, $IL-1\beta$ and COX-2, and increase $PGE_2$ production in trout head kidney macrophage cells, representing a strong inflammatory activity.

The gross appearance, cellular constituents, and quality of mucin clot of synovial fluid from the normal tibiotarsal joints of 57 healthy Korean cattle were investigated. The results obtained were summarized as followings. 1. The gross appearance of the synovial fluid were quite clear without any minute particles of flocculent, colourless (78.95%) or slightly yellowish (21.05%), and it did not coagulate within the 24 hours after sampling. 2. The mean number of leucocytes for the entire group was $127.68{\pm}13.84/mm^3$ (SE) with a range of 0 to $627/mm^3$ for individual samples. In the total cell count no significance among the investigated age and sex categories was found. 3. The mean differential values for the groups ware: neutrophil, $9.36{\pm}1.67%$; lymphocyte, $57.66{\pm}8.34%$; monocyte, $24.70{\pm}2.22%$; eosinophil, $1.45{\pm}0.27%$; and macrophage, $5.83{\pm}1.13%$. No basophils were observed in stained smears of synovial fluid. 4. Normal mucin clot quality was recorded for 94.7% of the animals, but 5.3% were observed to have fair mucin clot quality. Quality of mucin clot was approximately equal for bulls, cows, and calves.

수산 혈액학에 시판의 Diff-Quick kit를 사용할 수 있는지의 여부를 검토하였다. 제조사의 지시에 따라 뱀장어의 말초혈액의 도말표본을 염색하였을 때는 핵의 염색성이 불량하여 핵 내에 미염색의 부분도 남아 있고, 또한 세포질의 호염기성도 저하되었으며, 백혈구 과립의 염색도 불량하여 상법으로 사용하는 May-Glunward Giemsa염색에 비해 염색성이 나빴다. 그러나 염색 시간을 변경하여 solution I에 5초, solution II에 10초 염색 후 이온교환수로 세척하였을 때 양호한 결과를 얻었으며, 혈구의 분류도 가능한 것으로 나타났다. 이러한 염색 조건을 다른 어종인 메기를 비롯한 3종의 어류의 말초혈액의 도말표본에 적용해본 결과 이들 어류의 혈액 염색에도 적용 가능한 것으로 나타났다.

The bacterium Edwardsiella tarda was injected into healthy snakeheads (Channa argus) in order to prove the causative agent of ascite. The bacterium dominantly isolated from 2 cultured ascite snakeheads was injected into fish by the dose of $5\times10^6$ CFU/ 0.25ml, but the same dose of $0.65\%$ physiological saline was injected into the each control. The injected fish was divided into 4 groups such as intraperitoneal, intramuscle, control intra-peritoneal and control intramuscle according to their injection points. Each was composed of 10 healthy snakeheads respectively. Ascites and haemorrhagic ulcers became distinct 5 days after injection, but controls did not show any abnormal symptoms during the experimental period. Edwardsiella tarda was reisalated out of the injected fish's ascite, liver, kidney, spleen and haemorrhagic ulcer on the skin. Regardless of the injecting methods, liver was necrotized more severely than any other internal organ, but both the glomeruli of kidney and spleen were considerably damaged. Necrosis of muscle and a number of leucocytes were observed at the ulcerous region of the intramuscular injected fish. It is concluded that judging from the above results the Edwardsiella tarda is a causative agent to cause ascite in snakehead.

We have reported that kalopanaxsaponin A (KPS-A) Isolated from Kalopanax pictus have anti-rheumatoidal activity in the rat treated with Freunds complete adjuvant (FCA) reagent. In addition, it has been also reported that KPS-A is a potent antioxidant in the rheumatoidal rat. This research was undertaken to examine whether the saponins of KPS-A and -1 could adjust the abnormal lipid metabolisms and hematological changes in immunological diseases. KPS-A significantly inhibited the increases in both triglycerides and total proteins in addition to the decrease in total cholesterol induced by FCA reagent treatment. KPS-A treatment decreased the number of leucocytes elevated by FCA reagent treatment. Excess dose of the methanol extract produced no severe toxicity on the body weight, wet organ weights and hepatic functions. Since $LD_50$ value of K. pictus methanol extract was shown to be 4,033 ${mg/kg}$, it could be estimated to be a safe agent for anti-rheumatoidal herbal medicines.

The anti-inflammatory effect of Spirulina fusiformis on monosodium urate crystal-induced inflammation in mice has been investigated and compared with the non-steroidal anti-inflammatory drug Indomethacin. The paw volume, lysosomal enzyme activities, lipid peroxidation, anti-oxidant status and inflammatory mediator tumour necrosis factor-$\alpha$ were studied in control and monosodium urate crystal-induced mice after oral administration of Spirulina platensis in an experimental model for gouty arthritis. In the induced mice, the levels of lysosomal enzymes, inflammatory mediator tumour necrosis factor-$\alpha$, lipid peroxidation and the paw volume increased significantly, whereas the antioxidant status decreased when compared to control mice. $\beta$-glucuronidase and lactate dehydrogenase level were also found to be increased in untreated monosodium urate crystal-incubated polymorphonuclear leucocytes. After the oral administration of Spirulina fusiformis, the physical and biochemical changes observed in monosodium urate crystal-induced animals were significantly restored to near normal levels. The results clearly indicated the anti-inflammatory role of Spirulina fusiformis, a promising drug for gouty arthritis.

Morphogenesis of rat spleen was studied by light and electron microscope from the fetal stage till the newborn or adult stages. The results indicate as follows: at the 14th day of gestation rat spleen, as an early form, consists of intercellular spaces and mesenchymal cells. And at this stage the spleen is in a premature state, then it appears its adult condition in structures after the 7th postnatal day. Erythropoiesis is shown to be an active process in rat spleen beginning about the 18th day of gestation, and once established the process continues at least till the 7th postnatal day. At the 20th day of gestation, there are splenic nodules, trabeculae, venous sinus, and granular leucocytes such as neutrophils and basophils in rat spleen. Lymphocytes appeared to be well differentiated at the 7th postnatal day and were present till the adult stage. While degenerating erythrocytes are phagocytosed by macrophages. In conclusion, rat spleen started to be appeared from the 14th day of gestation and erythropoiesis in rat spleen was carried out for about 10 days between prenatal and postnatal stage. Erythrophagocytosis was accomplished by macrophages and it is suggested that the proper functions of rat spleen set off from the 7 th postnatal day when its structures are similar to the adult's.

The diagnostic effects of the Modified Whiteside Test(M.W.T.) and the California Mastitis Test(C.M.T.) for detection of bovine mastitis were studied using 372 quarter milk samples collected from six dairy herds in suburbs of Suwon city in order to compare the effectiveness of the two methods. The leucocyte count and bacteriological observation were also performed to support analysing the results. The results obtained were as follows; 1. The CMT showed more specificity than MWT for leucocytes in the abnormal milk. 2. When comparison was based on Identical ratings, agreement was obtained in 56.4% of the samples. The stronger reaction had the higher agreement and the CMT was found to be more specific than MWT in detection of the sub-clinical mastitis. 3. The CMT reaction was instantaneous and sufficiently clear-cut. 4. The results of the CMT leucocyte count and bacteriological observation were completely agreed in 69.9% of the samples. When degrees of reaction and the leucocyte count were considered, the CMT showed agreement in 93.5% of the samples.

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.
