This study was performed to investigate the serum creative kinase(CK) activity and CK isoenzyme in Jindo dog. Serum CK activity and CK-isoenzyme were analyzed in 53 Jindo dogs of both sexes. The mean value and normal range of serum CK activity were 24.1 lu/$\ell$ and 7-91 lu/$\ell$, respectively, in 29 female dogs, 24.8 lu/$\ell$ and 8-89 lu/$\ell$ in 24 male dogs. The CK activity of the Puppy showed a tendency to be higher than that of the adult. There was no significance between Puppy and adult. Three isoenzymes (CK-MM, CK- BB, and CK-MB) were recognized in serum. The mean percentages of female and male were as follows: 48.31fp and 48.1% for CK-MM, 35.49) and 33.61fp for CK-BB, and 8.2% and 10.1% for CK-MB in the puppy and 46.21% and 46.1 % for CK-MM, 36.3% and 37.6% for CK-BB and 10.5% and 9.5% for CK-MB in the adult.

Mitochondrial DNA(mt DNA) of Mammalian is the circular one which the 16.5K base pairs and show the maternal inheritance. Evolutional speed of nucleotide sequence is very fast. So that polymorphic analysis of mt DNA provide the useful informations to investigate the genetic relations of interspecies. Authors trials were focussed to compare with the polymorphic differences of mitochondrial DNA between Jindo and Japanese mongrel dogs. DNA was extracted from bloods of 21 head of Jindo dogs and 20 head of Japanese dogs and isolated using 10 kinds of restriction endonucleases(Apa I, BamH I, Bgl II, EcoR I, EcoR V, Hinc II. Hind III, Pst I, Sty I, Xba I) and then separated by the agarose gel electrophoresis. After sourthern blotting hybridization was completed using the mtDNA of Japanese mongrel dogs as a probe. Autoradiography was used to compare the polymorphism of mtDNA both dogs. The results obtained were as follows; 1. mt DNA of Jindo dog showed polymorphism resulting cleavage with four kinds of restriction endonuclease, Apa I, EcoR V, Hinc II, Sty I. While in the Japanese mongrel dogs observed the polymorphism in the five kinds of restriction endonuclease supplemented with EcoR I. 2. Compared with both dogs the frequency differences of DNA polymorphism were recognized in the specific restriction endonuclease Apa I. Consequently in the restriction endonuclease Apa I both dogs classified with three types as A, B, C however in the Jindo dogs frequency of C type was 71.5 percent but in Japanese mongrel dogs observed 45 percent in the A type. 3. DNA polymorphism obtained from the use of five kinds of restriction endonuclease were classified with seven types. In Jindo dogs frequency was highest in the type 6 as 71.4 percent but in the Japanese mongrel dogs showed 35 percent in the type 5. 4. Genetic distances calculated by NEI method showed 0.0089 in Jindo dogs and was 0.0094 in the Japanese mongrel dogs.

In order to study on the Sertoli cell, we attempt have been made to measure the average number of each germ cells per Sertoli cell on the 12 stages of cycle in matured korean Jindo dog. The fine structure of Sertoli cell junctional specialization was studied with electron microscope. The results were summarized as follows; 1. The average number of various germ cells associated with Sertoli cell was 9.77 to 13. 80 through stages of cycle and the total average number was 11.62. 2. Sertoli-Sertoli cell junctional specialization was present in seminiferous epilthelium, and Sertoli-spermatid cell junctional specialization rose from stage 8 spermatid, persisted to step 13 spermatid and then disappeared. The structure of Sedoli-spermatid cell juncticnal specialization was not similar to that of Sertoli cxlls. 3. Just after spermiation, free-surface of Sertoli-spermatid cell junctional specialization was replaced by Sertoli cell cytoplasm with tubulobulbar complex at the neiglaboring region observed. 4. The Sertoli cell process was located within the cytoplasm of late stage spermatids. Some membranes of residual body and spermatid cytoplasm partly disappeared, resulting in opening of the cytoplasm of spermatid into that Sertoli cell. This fact suggested that spermatid cytoplasm was partly eliminated.

To investigate the cycle and relative frequences and the fine structure of seminiferous epithelia in mature Jindo dogs, histologic study was performed. The results obtained were summarized as follows; 1. Type A spermatogonia appeared approximately 1.6 times as many at stage II as compared to stage I while type In spermatogonia appeared small amount in stage III, IV and V. type B spermatogonia were found during the stage VI to VIII, though not detectable during stage I to V. The type B spermatogonia divided at stage VII to produce the preleptotene primary spermatocytes at stage VIII. The number of primary spermatocytes of the leptotene phase markedly increased during stage I to II, and the primary spermatocytes of the pachytene phase were shown the least in number at stage IV. The secondary spermatocytes could be seen only at stage IV. 2. The relative frequencies of each stage from stages I to VIII of the cycle of seminiferous epithelia were 31.6, 11.9, 10.0, 3.2, 8.2, 10.1, 11.7 and 13.2% respectively. 3. On electron microscopic observations, acrosomal vesicle of spermatids appeared larger though the bulk of germ cells were the morphologically same as those of the other animal species. Thread line structures light microscopically observed in the cytoplasm of Sertoli cell were the longitudinal orientation of mitochondria.

Generally, it is known that the composition of the cation of the dog's RBCs is high in potassium(K) and low in sodium(Na). However, it is reported that certain kinds of dogs have HK, HG phenotype which contains a large amount of reduced glutathione(GSH) by the effect of Na-K pump on the cell membrane of RBC with high concentration of K and low concentration of Na. Although this HK phenotype is not regarded as a disease, it is supposed to be an important assignment to examine the distribution and the occurrence rate of the dogs that contain HK cell in their RBCs for the proper clinical treatments as these HK dogs are very sensitive to aromatic disul-fide or onions and have a tendency to cause hemolysis. Accordingly, present study was performed to measure the concentration of K, Na and GSH in the RBCs of Jindo dogs and that of Dosa dogs at the same time.

The present study was conducted in order to get the relationship of heartworm, Dirofilaria immitis and eosinophils in blood of Jindo dogs. Blood samples were taken from 141( man 31, womam 110) of yellow, 44 ( man 17, woman27) of white Jindo dogs in Jindo area. The results obtained in this study were summarized as follows : 1. There were no significant differences of the hematological values in comparison with others reported values, but the mean corpuscular hemoglobin concentration and the number of eosinophils were high in comparison with other reported values. 2. The mean values of total white blood cell count(P<0.05), neutrophil(P<0.05) and monocyte(P< 0.05) were that the yellow dogs and a tendency toward fisher values than the white dogs, but no significant differences were observed. 3. Age-related differences were detected for the total erythrocyte count(P<0.05), hemoglobin content (P<0.001), PCV(P<0.001) and the number of eosinophils(P<0.001). 4. The direct and indirect eosinophil counts were increased with age, there were no significant differences of the values between two groups. 5. Dirofilaria immitis was found in 34(18.4%), increased with age and were relatively significant differences in areas of the 185 Jindo dogs. 6. Survey for hematological values of Dirofilaria immitis infected dogs with direct and indirect method, mean values of eosinophil were 2,788/ ${\mu}l,$ 3,021/ ${\mu}$l, respectively. They showed that eosinophil had a tendency toward higher values than others, but others were no significant differences.

The lectin-binding patterns in the testis of the sexually matured Jindo dog were investigated to study the distribution of glycoconjugates in the seminiferous tubule under light and transmission electron microscopy. Positive reactions to Wheat germ agglutinin(WGA) and Dolichos biflorus agglutinin (DBA) were observed in the Sertoli cell and in the residual body of spermatid with a stronger reaction in the Sertoli cell to the lectins than in the residual body. Strong reactions to Soybean agglutinin(SBA) and Peanut agglutinin(PNA) were observed in the acrosome vesicles of the Golgi- and cap-phase spermatid, while a moderate reaction was observed in the acrosome-phase, maturation-phase spermatid and the residual body. The acrosome area of the spermatid reacted intensively to Griffonia simplicifolia agglutinin( GS-I) when the cell was in the acrosome-phase and maturation-phase, and the same reaction to the GS-I was observed in the residual body. However, the seminiferous tubule did not react to Ulex europeus agglutinin I(UEA-I). The gold-labelling of the Sertoli cells with DBA resulted in positive reactions of the Sertoli cell column and processes when observed under the electron microscopy, while the Golgi-, cap- and acrosome-phase spermatids reacted positively to SBA in the peripheral low-dense area of the acrosome vesicle of spermatid. Based on these results, we concluded that differences in the lectin-binding pattern of the seminiferous tubules were recognized in the Jindo dog compared to other animals.
