1.Studies on Amphistoma in Korean cattle.
The Korean Journal of Parasitology 1972;10(1):34-43
The present studies were done to determine the prevalence of Paramphistoma in Korean cattle. Material have been collected by authors at the slaughter house of Pusan in Korea from February to July of 1966. The fixing solution used were 10 percent formaline, Carnoy-solution, Zinker and Bouin solution for total worm body preparation. The staining was done with acetocarmine and Delafild's Hematoxylin for total preparation and double Hematoxylin-Eosin staining for microscopical section slides. The following results were obtained: The authors have identified six species of Amphistoma from Korean cattle, and these are Paramphistoma orthocoelium, P. cervi, P. explanatum, P. gotoi, Gastrothylax elongatus and Gastrothylax cobblodi. The prevalence status is as follow: Paramphistoma orthoceolium and Gastrothylax elongatus are very common and Paramphistoma cervi, Paramphistoma explanatum are rather common, but Paramphistoma gotoi and Gastrothylax cobblodi are very rare in Korean cattle.

The Korean Journal of Parasitology 1973;11(2):83-96
Authors were observing a case of infection with Thelazia callipaeda in Korean girl, on 11th Sep. in 1971. The case was 23 years old Korean girl who visited with the complaints of foreign body sensation and lacrimation in right eye. The worm had slender creamy white which was fixed in 10 percent formaline solution. The worm is 10.5mm in length, 0.5mm in body diameter. The oral end in provided with a chitinoid capsule. Esophagus moderately short, tail blunt, poserior extremity had a distinctly recurved. Spicules dissimilar, left spicule is 0.1mm in length, and right spicule is 0.08 mm in length.

The Korean Journal of Parasitology 1975;13(1):53-59
A Study on glutamic pyruvic and oxaloacetic transaminase of different organs(e.g intestine, seminal vesicle, reticular tissue, uterus, ovary, testes) in Ascaris lumbricoides suis have been investigated. The activity of transaminase were determined on the whole homogenates and subcellular fractions separated by differential centrifugation. The activity of glutamic pyruvic and oxaloacetic were assayed by colorimetric method of Reitman-Frankel. The results were obtained as follows: About ninty percent of the glutamic pyruvic and oxaloacetic transaminase in different organs was found to be localized in the supernatant fraction with the separation of differential centrifugation. And it was found that ten percent of glutamic pyruvic and oxaloacetic transaminase exists in the mitochondrial fraction. The specific activity of glutamic oxaloacetic transnaminase in different organs was relatively higher than the glutamic pyruvic transaminase activity.

4.Cytochemical study on lipase and nucleic acid in Trichomonas vaginalis.
The Korean Journal of Parasitology 1975;13(1):47-52
Cytochemical demonstrations of lipase and nucleic acid in Trichomonas vaginalis were attempted. Modified Gomori tween method for lipase and acridine orange method for nucleic acid was applied. Trichomonas vaginalis incubated in the isolation mediurn (C.P.L.M.) were pooled and fixed using 0.1 N McIlvaine buffer saline and cold acetone for lipase and Walpole acetate buffer saline and acetic alcohol for nucleic acid. The results were obtained as follows: Activity of lipase and nucleic acid were recognized in the cytoplasm of T. vaginalis as scattered positive granules stained in blue yellow-green bright reddish color respectively. However these reactions were not shown in nucleus, nuclear membrane, undulating membrane etc. Present authos believe the negative finding of acridine orange staining in nucleus should be studied further.

5.Histochemical studies on the relationship between the ascarides of man and pig..
The Korean Journal of Parasitology 1963;1(1):15-21
The histochemical study, especially the demonstration of alkaline phosphatase and acid phosphatase was carried out in order to differentiate ascarides of human and pigs. The experimental material were obtained from naturally contaminated men and pigs. As the histochemical staining methods the Gomori's was applied for acid phosphatase and Takeuchi and Takami's for alkaline phosphatase. The results obtained were summerized as follows : In the pig's ascarides, alkaline phosphatase was richly found in the subcuticular tissue, lateral line, median line, strial zone and epithelial cells of the intestine, epithelial cell and basal membrane of the ovary, the same part of the uterus and also in eggs. Acid phosphatase in the pig's ascarides were distributed in the same part as alkaline phosphatase. It, however, was darker brown in the soft tissue of the lateral line, epithelium of excretory canal, median bundle, whole zone of the intestine and intestinal contents. In the human ascarides, the alkaline phosphatase was distributed in the testes and the parts where the acid phosphatase was found in the pig ascarides. The acid phosphatase in the human ascarides was demonstrated in the subcuticular tissue, soft tissue of lateral line, epithelium of excretory cells, strial zone, transparent zone, granular zone and epithelial zone of esophagus and intestine, ovary, ova in the uterus, epithelial cell and basal membrane of the uterus and in testes. In the pig's ascarides, the area of distribution of alkaline phosphatase was restricted, but that of acid phosphatase was wider. In human ascarides, the area of distribution of alkaline phosphatase and acid phosphatase was not significantly different, but in some part showed slight difference. Above mentioned finding suggest that the distribution of phosphatase could be utilized for the differentiation of ascarides of human and pig.

The authors carried out histochemical studies on Clonorchis sinensis, especially, histochemical demonstration of carbonic anhydrase activity. Kurada's method was applied for the histochemicl staining in this study. The result obtained were summerized as follows : Carbonic anhydrase activity was intensely positive in oral sucker cells, reticular tissue cells, epithelium of the intestine and testes, more or less intensely positive in vitelline gland cells and yolk of eggs as well.

In order to study species of the Fascioloidae in Korea, a series of morphological and taxonomical studies were carried out and the following results were obtained. Among the species of the Fascioloidae in Pusan area, intermediate form (F. indica?) were 70 percent, F. gigantica 25 percent and F. hepatica, 5 percent. None experimental, natural infective rate of the Fasciolosis was 3.3-3.4 percent among the cattles (Bos taurus var. domesticus) in Pusan area.

The purpose of the present study is to demonstrate the distribution of carbonic anhydrase pattern in the various termatodes (Fasciola gigantica, Paramphistoma orthocoelium, Paragonimus westermani) by means of Kurada staining method, and to correlate these findings with the histochemical data and harboring location. The results are summarized as follows: In Fasciloa gigantica, carbonic anhydrase activity was positive in the vitelline gland cells and eggs in the uterus. In Paramphistoma orthocoelium, carbonic anhydrase activity was positive in the vitelline gland cells and eggs in the uterus. In Paragonimus westermani, carbonic anhydrase activity was positive in intestinal mucous membrane, vitelline gland cells and eggs.

This is a case report of intestinal eosinophilic granuloma caused by Ascaris ova and worm which is supposed to be rare in Korea. Case: A 23 year old healthy female reached Pusan Sanitation Hospital with complaints of high fever and abdominal pain on December 3 in 1966. Examination: Her temperature was 99.6 F. Pulse 80. Abdominal palpation showed muscle rigidity and tenderness. On the right side of the abdomen diagnosis due to ruptured appendix was made, and a laparotomy was performed the same day. Operation: Intestinal perforation by a Ascaris worm in the caecum about 7 cm from the ileo-caecal junction was also found. The worm was liquefied already. The intestine was edematous . Numerous rice sized nodules were seen on the intestine. The omentum was markdly inflammed and was adhered with a fist size mass. The mass and appendix were also resected in order to do a histological study. Pathology: Two kinds of tissues were examined : one a mesenteric mass, the other lymph node. Microscopically, it showed intensive and entirely necrotic tissue in which numerous parasitic ova were surrounded by granulomatous inflammatory cells with eosinophiles . The parasitic ova were degenerative and partialy necrotic although they had three layers of egg shell which are identified with Ascaris ova.
