The malic dehydrogenase activity was determined by the modified method of Ochoa (1955) using tissue homogenates of various parasitic helminths. Worm parasites were mostly collected from local abattoir, and removed from the organ or tissues of the naturally infected animal hosts, and some materials were also obtained from the human hosts. The helminths used in this experiment include 3 kinds of nematodes, 5 kinds of trematodes, and 8 kinds of cestodes. They were throughly washed and homogenized in glass tissue grinder in ice chilled water bath, and then centrifuged. The supernatants were designated as enzyme preparations. The hydrogen concentrations of buffer solution were pH 1.4, 2.7, 3.5, 4.2, 5.2, 7.4, 8.2, 9.3, 10.2, 11.6, and enzymatic reaction of this experiment was performed at incubation temperature of 20, 30, 40, and 50 C. The extinction of Nicotinamide Adenosine Dinucleotide (NAD) was measured by spectrophotometry at the wave length of 340 millimicron. The results of the experiment were as follows: The malic dehydrogenase activity occurred over all kinds of parasitic helminths used in this study. And the activity on sparganum turned out to be highest. All helminths displayed their maximum activity in the range of alkaline pH. A comparison of the effects of temperature and substrate concentration on the enzyme activity was made among these helminths. However, no definite relationship among them has been detected. The significance of the existence of this enzyme in the helminths was briefly discussed.

Nasal congestion is one of the most common symptoms of medical complaints. Snoring is caused by vibration of the uvula and the soft palate. Nasal obstruction may contribute not only to snoring and obstructive sleep apnea (OSA) but also impair application of continuous nasal positive airway pressure (CPAP), which is the most widely employed treatment for OSA. Total or near-total nasal obstruction leads to mouth breathing and has been shown to cause increased airway resistance. However, the exact role of the nasal airway in the pathogenesis of OSA is not clear and there is no consensus about the role of nasal obstruction in snoring and sleep apnea. Some reports have failed to demonstrate any correlation between snoring and nasal obstruction. On the other hand, opposing reports suggest that nasal disease may cause sleep disorders and that snoring can be improved after nasoseptal surgery. Reduced cross-sectional area causes increased nasal resistance and predisposes the patient to inspiratory collapse of the oropharynx, hypopharynx, or both. Discrete abnormalities of the nasal airway, such as septal deformities, nasal polyps, and choanal atresia and with certain mucosal conditions such as sinusitis, allergic rhinitis and inferior turbinate hypertrophy can cause snoring or OSA. Thus, these sources of nasal obstruction should be corrected medically or surgically for the effective management of OSA and adjunctive for CPAP.

Since Senoo and Lincicome (1951) first have brought up for attention to the existence of malayan filariasis in Korea, several reports on the epidemiological investigations of the disease had already been made by many workers. However it is little known what kind of mosquitoes are involved as the major vectors in main endemic areas. In Cheju-Do, known as one of main endemic areas in Korea, Aedes togoi is most likely suspected as an important vector because of their abundant collections and vigorous biting attack to human. As a part of studies on filariasis in Korea, an essential preliminary is to determiine whether this mosquito, Aedes togoi collected in the above areas is receptive to the microfilariae of B. malayi. Therefore, the present paper is concerned chiefly with the development of B. malayi in A. togoi. It is also hoped that the studies on the larval morphology in the mosquito host and the structure of microfilariae will provide the base line data required for later investigation of the different vector hosts. The studies were summarized as follows: The measurements of the fixed points in percentage of the body length of microfilariae from the Giemsa stained thick films were made, and they showed that cephalic space was 8 percent,cephalic space length to width, 1.3:1, nerve ring, 21.2 percent, excretory pore, 30.8 percent, excretory cell, 36.5 percent, R1 cell, 66. 5 percent, anus 80.4 percent and body length 202 micrometer(l81-228 micrometer) maximun width 7.6 micrometer. A study on the development of microfilaria malayi in the mosquito, Aedes togoi was carried out at room temperature (24-30 C). Mosquitoes used in this experiment were reared from larvae collected from the tide water rock pool in the coastal areas of Cheju-Do and they were fed with a blood meal of carrier donors whose microfilaria densities were in the range from 0.5 to 0.7 per cmm of blood. All of the microfilariae ingested by mosquito exsheathed in stomach, penetrated into the body cavity and then migrated into the thoracic muscles of the mosquitoes within 10 hours, after two moults in the mosquito host, the length of the developing 3rd stage larvae reached in size of 1.3-1.7 mm x 23-32 microns with anal ratio, 2.6 to 3.6. The first appearance of 3rd stage larvae in the mosquito host in this experiment was in 8th day after infection. The larvae were observed in the various cavities of mosquito, such as head, thoracic cavity, abdomen, halters, eye and legs. During the larval development in larval development in the host, the shortening of body length was first observed and then elnongation was followed until becoming 3rd stage larvae. Aedes togoi was proved to be the most suitable host for this species of microfilaria malayi in the above endemic areas.

It has been well known that infertile women experience not only emotional disturbance but also stress. But there is no concern about male infertility patients. So phychiat.ic symptoms were studied with SCL-90 (Symptom Check List-90) in 30 infertile men who was operated testicular sperm extraction (TESE) in Samsung Cheil Hospital and in age matched 31 fertile men from Jan. 1998 to Aug. 1998. In 5 symptom dimensions (Obcessive-Compulsive, Interpersonal Sensitivity, Depression, Phobic anxiety, Psychoticisim) scores. The Infertile group scored significantly higher than the control group. The result revealed that infertile men also experienced substantially more psychiatric symptoms than fertile men. Considering this results, psychiatric evaluation and tender care by infertility specialist are necessary for infertile men during and after evaluation and treatment.

This sutdy was performed to find out a LD isoenzyme pattern in neoplastic tissue of gastric carcinoma and in gastric mucosa with intestinal metaplasia, which has been known as premalignant lesion. The specimens used in this study were 18 stomachs with caarcinoma and 8 stomachs with peptic ulcer as control, and wer obtained by subtotal or total gastrectomy at Pusan National University Hsopital from Oct. 1987 to Sept. 1988. Total LD activity and its isoenzymes in body and antral mucosae and neoplastic tissue of stomach were assayed, and analysed statistically from several points of view. The results obtained were summarized as follows: 1) There was no significant difference in total LD activity between univolved body and antral mucosae of stomach with carcinoma, and between mucosa of stomach with peptic ulcer and univolved mucosa of stomach with carcinoma. 2) Total LD activity in the neoplastic tissue of gastric carcinoma was significantly higher than those of univolved body and antral mucosae of stomach with carcinoam or that of stomach with peptic ulcer, but no significant difference was observed among histological types of gastric carcinoma. 3) The uninvolved body mucosa of stomach with carcinoma or peptic ulcer showed a pattern of LD1 predominance and increas of H to M ratio, while the antral mucosa of stomach with carcinoma or peptic ulcer showed a pattern of LD3 predominance and decrease of H to M ratio. 4) The LD4 and LD5 fractions in antral mucosa with moderate to severe intestinal metaplasia were slightly increased than those of antral mucosa with nil to mild intestinal metaplasia, but did not show statistically significant difference. 5) Marked increase of LD5 fraction was found in neoplastic tissue of gastric carcinoma, and thus ratio of H to M subunit in neoplastic tissue was significantly lower, as compared with body or antral univolved mucosa of stomach. In conclusion, the neoplastic tissue of gastric carcinoma and gastric mucosa with intestinal metaplasia show substantially predominant "M" subunit as well as increased total LD activity.

Reconstruction of cruciate ligament has been controversial. Autogenous grafts has been used with inconsistent success rates due to their variable strength and limited length. If any autograft could cover such drawbacks it could surpass the advantage of artificial ligaments also. Recently, we used partial Achilles tendon autograft in reconstructive operation of anterior cruciate ligament with promising result. The main advantages of this Achilles tendon autograft are its sufficient length and strength. Preliminary study was done in 11 patients who received reconstruction of the anterior cruciate ligament using partial Achilles tendon autograft. The results were as followings :l. Anterior cruciate ligament reconstructions were done in 11 patients, with follow-ups ranging from 5 to 12 months, average being 8 months. 2. Average preoperative knee score was 49.1, and it was improved up to 87.4 after operation. 3. Among the 11 patients, 6 belonged to the Excellent, 4 to good, and 1 to fair. 4. Achilles tendon autograft turned out to be a good autograft substitute for the anterior crucate deficient knee. The results were promising. Long-term follow-up is needed to confirm the final status of the operated knee.

An immunohistochemical stain for the Rb tumor suppressor gene product was performed in pathologic specimens from 72 primary lung cancer patients to study the correlation between its expression and histologic type, cancer differentiation, clinical stage and survival rate. The expression of the Rb protein was positive in 34 cases(47.2%) and negative in 38 cases(52.8%). The Rb protein was not expressed in 16 of 42 cases(38.1%) in squamous cell carcinoma, in 17 of 23 cases(73.9%) in adenocarcinoma, in one of three cases(33.3%) in undifferentiated large cell carcinoma, in two of two cases(100%) in small cell carcinoma, in one of one case(100%) in an adenosquamous carcinoma and in one of one case(100%) in an atypical carcinoid. There were significant difference of the Rb protein expression between squamous cell carcinoma and adenocarcinoma(p<0.05). The expression of Rb protein was not correlated with degree of cancer cell differentiation and clinical stage of the lung cancer(p>0.05). The two year survival rate for patients with the Rb positive was 65% compared with 37% for those with the Rb negative which was significant(p<0.05). This result suggests that an altered or the absence of the Rb protein in cancer cells can be a valuable prognostic factor in the lung cancer.

OBJECTIVES: The study was to examine major factors that affect suicidal ideation of elderly in urban areas. METHODS: The subjects were 302 elders who voluntarily participated in the study. The instruments for this study were scale for suicidal ideation(19 items), family concord (20 items), CED-depression(20 items) and family inventor of life events and changes(FILE, 22 items). Frequency, percentage, t-test, ANOVA, Duncan test, Pearson' correlation coefficient, stepwise multiple regression with SPSS program were used to analyze the data. RESULTS: The average score of suicidal ideation was 14.88. Suicidal ideation was positively related to depression and stress, but negatively related to family concord. depression, family concord, stress and health status accounted for 86.1% of the variance in suicidal ideation. These results suggest that family concord, depression and stress can be potential risk factors for suicide of elderly. CONCLUSIONS: These findings may give useful information for developing suicidal prevention program on old age.
