Serum chemical values were determined in blood samples obtained from 179 normal, healthy Jindo dogs of both sexes that ranged in age from 3 months to 10 years. Female dogs had higher total protein and albumin values than their male counterparts. Age-related differences were detected for serum proteins, inorganic phosphate, glucose, and blood urea nitrogen levels. The GGT level Was within the normal range in dogs.

The origin of Jindo dogs has been controversial. It has been informed by words of mouth that they are the offsprings of either the digs of Sung dynasty (960~1279 A.D.) in China or the Mongolian dogs. Some breeds of dogs in Japan now have almost same appearance as Jindo dogs. The authors reviewed the history of Japan and found that Korean hunting dogs were sent to Japan in early 5th century, which was before Sung dynasty of China. Dr. Jae-Keun Ryu of National Institute of Environmental Research has done some work on serums of dogs of both Korea and Japan; the results of his serological and molecular biological studies indicated that Korean dogs were sent to Japan 1,300~2,500 years ago. Jindo dogs appear to be the descendants of the dogs of the Stone Age. They have adapted themselves to the unfavorable environment of Jindo island so that they can maintain pure line-age and wild nature until today. It was concluded that they are Korean native dogs, not the offsprings of the dogs of Sung dynasty or the Mongolian dogs.

In order to investigate the spermiogenesis of the Korean Native Jin-do dog, the tissue sampled from the testis and the epididymis of matured dog were conventionally prepared as thin sections. And then these sections were observed under a transmission electron microscope. Based on the development of various permanent organelle and certain transient structures, the spermiogenesis of the dog could be divided into four major phases: Golgi, cap, acrosome and maturation; and these phases had been futher subdivided into seven stages. In the maturatin phase, the karyoplasm has been condensed completely and the nucleus eleongated as the movement of the unclear ring. The equatorial segment has notable waist-form at the late acrosomal stage. In the cross section of the tail, it shows a typicl 9＋9＋2 pattern of the axial fiber bundle condisting of the dense fibers, the inner fibers, and a central pair. The dense fiber number 1, 5, 6, and 9 were larger in diameter than the rest of the dense fibers.

A four-year-old female Jindo dog was admitted to the hospital because of bilaterally symmetrical alopecia and inappentence. Systemic abnomalities detected on physical examination were obesity, bradycardia, exercise intolerance, mental dullness and hypothermia. Dermatologically symmetrical alopecia on the back, trunk and dorsal tail, and ventral hyperpigmentation were observed. Also face was very tragic. The level of basal $T_4$ was 0.01ug/dl. In TSH stimulation test $fT_4$ value was 0.08ng/dl. After treatment was initiated with L-thyroxine the dog's general condition was improved at 4 weeks.

A 13-years and 8-months old Jindo dog showed vomiting and pale red vulvular discharge. At necropsy, the uterus was swollen and endometrium was diffusely thickened by numerous protruding cysts which measured approximately from 0.5 to 1 cm in diameter. On sectioning the cysts exuded pale red watery fluid. histologically the endometrium was thickened and characterized by mild to moderate edema congestion and hemorrhagic foci. The cystic endometrial glands were lined by a single layer of flattened cuboidal or vacuolated columnar epithelium. Occasional dilated glands had traversed through the submucosa into the myometrial region. Afew mixed inflammatory cells infiltrated in the lamina propria. Bacteriologically Escherichia coli was isolated from the uterine contents. Gross and microscopic finding were consistent with cystic endometrial hyperplasia.

In an effort to obtain basic data of carbohydrate metabolism during spermiogenesis of the sexually-matured Jindo dog, the glycogen distribution in the testis was investigated by light and transmission electron microscopy. Periodic acid thiocarbohydrazide silver proteinate physical development(PA-TCH-SP-PD) staining method provided better results in the detection of glycogen granules from Sertoli cells and germ cells than the periodic acid schiff(PAS) staining method did. Pre-treatment of the tissue sections with ${\alpha}$-amylase elicited a significant decrease in PA-TCH-SP-PD stained granules, which suggested that the stained granules were of glycogen origin. High concentration of the glycogen granules were observed in the Sertoli cells, especially in its column, sheet-like processes, club-like processes, and tubular processes. The glycogen granules were unevenly distributed in some Sertoli cell columns. These results strongly indicated that the Sertoli cells of Jindo dogs showed vigorous activity of carbohydrate metabolism.

This study presented the results of ophthalmic examinations performed on 545 Korean Jindo dogs. The most prevalent ocular variation within normal limits was hyoid vessel remnant (12.7%) and prominence of lens suture was also noticed (1.7%). The most common ocular diseases were retinal scars (6.8%), focal cataract (4.6%) and persistent pupillary membrane (4.2%). Inherited ocular diseases found in this study were persistent pupillary membrane (4.2%), persistent hyperplastic primary vitreous (0.6%), retinal dysplasia (0.6%), entropion (0.4%) and progressive retinal atrophy (0.4%). The prevalence of ocular diseases was higher in Male than in Female and proportionately higher in the older dogs. The most prevalence was shown in white coat color dogs. The fundus color changes according to the age was not related in coat colors and shown same pattern.

It has been known that garlic, one of the essential ingredient in korean food, has a hypotensive effect. and it is reported that they lower the level of triglycerides, cholesterol and glucose in blood. Especially, the sulfur containing amine acid and the derivatives of the garlic has the counteracting effect to heavy metals. Nowadays, the garlic is known for its efficiency for the various kinds of cancer, neoplasms, hypertension, arteriosclerosis and apoplexy. But, it is reported that the intake of the excessive amount of garlic causes hemolytic anemia recently. The hemolytic anemia is more severe especially in HK phenotype dogs which has a Na-K-ATPase activity. Therefore, this study was performed to examine the effect on the blood of the HK phenotype Jindo dogs when administered the excessive amount of garlic. HK phenotype group showed the significant decrease on RBC, WBC, PCV, Hb, MCV, MCHC, GSH, Met-Hb but LK phenotype group didn't show the significant decrease.

Observations were made on the infection rate of common internal parasites in Jindo dogs from January to March, 1989. Fecal samples were collected from 115 Jindo dogs in Jindo area. On the basis of egg counting, the following results were obtained； 1. Of 115 fecal samples, 65.2％ were appeared as positive, Dogs from intensive dog-rearing places have lower infection rates than others. 2. Of the parasites detected, Toxocara canis was the most commonly encountered (26.1%). 3. Ascarids, flukes and coccidia were more prevalent in pups than in mature dogs, whereas hookworms were detected less often in young dogs than in older ones.

2세의 암컷 진돗개가 3개월간 혈액성 질분비물과와 외음부 종창을 주증으로 내원하였다. 질에 형성된 종괴는 조직병리학적 검사로 개 전파성 생식기 육종으로 진단되어 vincristine sulfate$(0.5 mg/M^{2})$을 1주 간격으로 3회 정맥주사를 실시하면서 혈액, 병리조직 검사 를 병행하였다. 종괴의 크기는 투여 후 1주부터 급격히 감소되었으며 조직소견상 종양세포는 세포질의 공포변성, 핵농축 및 붕괴, 혹은 apoptosis가 관찰되었다. 4주째 종괴는 완전히 소실 되어 치료를 중단하였고 혈액학적 검사 결과 부작용은 없었다. 마지막 투여후 10주째 건강한 새끼 4마리를 자연 분만하여 개 전파성 생식기 육종에서 vincristine 단독 투여로 우수한 치료 효과를 얻었다.
