In order to determine the status of Enterobius vermicularis infection among schoolchildren in suburban areas of Myanmar, 761 primary schoolchildren in 3 different townships around Yangon City were subjected to a survey using cello-tape anal swabs. The subjected schoolchildren were 383 boys and 378 girls who were 5-7 years of age. Only 1 anal swab was obtained from each child. The overall egg positive rate of E. vermicularis was 47.2% (359 positives), and sex difference was not remarkable (48.6% in boys and 45.8% in girls). However, the positive rate was the highest in South Dagon (54.6%) followed by Hlaing Thayar (43.8%) and North Dagon (34.8%). This difference was highly correlated with the living standards of the people in each township. Nucleotide sequence of the 5S rDNA from the eggs on the cello-tape (2 children) revealed 99.7% identity with that of E. vermicularis reported in GenBank. The results indicated that E. vermicularis infection is highly prevalent among primary schoolchildren around Yangon, Myanmar.

A total of 738 samples was collected to survey the helminthic infections of residents in two rural areas near Ulaanbaatar, Mongolia for 2 weeks from July 23 to August 2, 1998. Among 391 scotch-taped slides of anal swabs of children and of young teenagers, Enterobius vermicularis eggs were detected in 138 cases (35.3%). With the fecal samples of 206 Kato-Katz thick smear slides from adults, the eggs of E.vermicularis were observed in 9 cases and Taenia sp.in one case, respectively. And by ELISA on 141 blood samples absorbed to blood sampling paper,12 cases (8.5%)were found to be positive against the hydatid cyst antigen. Enterobiasis and hydatidosis are two major endemic diseases which are related closely to the life style of Mongolian.

An epidemiological study was undertaken to estimate the prevalence of Enterobius vermicularis infection among the primary (and infant) school schildren in Ysngyang-gun, Kyongsangbuk-do. During the period from 2 to 14 December 1983, a total of 2,227 school children in 13 schools were examined one time by means of scotch-tape anal swab technique with a simple questionaire study on perianal itching, enuresis and school record. The results are as follows: 1. The overall egg Positive rate was 64.1% and the rate ranged from 46.6 to 86.7% by schools. 2. The egg positive rates of boys and twirls were 60.5 and 68.0% respectively and the difference was statistically significant (P<0.005). 3. There was noted a tendency of decrease in prevalence by increase of the age of children. 4. It was revealed that perianal itching and school record were significantly correlated with E. vermicularis infection (P<0.05) while not in case of enuresis (P>0.1).

Enterobius vermicularis (pinworm) infestation in present day Korea has become one of nationwide problems. But, the incidence of pinworm infestation having been reported by many workers was almostly the data for specific groups. The incidence of pinworm infestation for 208 families of 760(male; 30, female;420) middle class inhabitant of Seoul, 238 subrural inhabitants in Gyeonggi Province and 150(male;77, female;73) rural primary students in three different districts were examined by modified Gralam's scotch-tape swab method. The results are summarized as follows; 1. The incidence of nationwide infestation a. The nationwide incidence of pinworm infestation of the 1,148 specimens examined was 28.7% (male; 27.5%, female; 29.6%). b. The highest incidence was found among 5-14 years of age. c. In comparison of the incidence by the area, the highest incidence was found among subrural area, next among rural area and the lowest among urban area. 2, Urban area a. The incidence of the 760 inhabitants examined was 23.2% (male; 24.1%, female; 22. 3%). b. The incidence of the parents group was 12.2% and children group was 30. 30.3%. c. In the parents who hold one or more pinworm poitive cases among children, the incidence of father group was 13.2% and mother group was 29.7%.3. Subrural area a. The incidence of the 238 inhabitants examined was 42.9% (male, 40.8%, female; 44.4%). b. The cumulative positive rate of anal swabs showed increasing tendency. c. Worm collection rates after chemotherapy of 98 inhabitants were 54, 0%. d. In scotch tape anal swab only one times, diagnostic value was 74.0%. e.

To evaluate the parasitic infection rates among inhabitants in urban area of Seoul, Korea, a total of 5,275 stool and anal swab specimens was obtained from 2,527 male and Z,748 female living in 24 Dongs of 17 Kus. Cases were sampled randomely to represent 1,000 inhabitants refereed to the census in 1980. The methods employed were formalin ether technique to detect helminth ova and protozoan cysts and scotch tape anal swab technique to detect eggs of Enterobius vermicularis. The results obtained are as follows ; 1) Total positive rate of helminthes was 23.5% among 5,275 (male 22.5% and female 24.5%) specimens. Nine kinds of the helminthes were detected and infection rates of each helminth were; Ascaris lumbricoides 4.1%, Hookworm 0.1%, Trichuris trichiura 11.1%, Trichostrongylus orientalis 0.1%. Clonorchis sinensis 1.2%, Metagonimus yokogawai 0.1%, Taenia spp. 0.2%, Hymenolepis nana 0.3 and Enterobius vermicularis 9.6%. 2) Total positive rate of intestinal protozoa was 1.4%. Four kinds of the protozoan cysts were detected and the infection rates of each protozoa were; Entamoeba histolytica 0.15%, E. coli 0.4%, Endolimax nana 0.04% and Giardia lamblia 0.89%. 3) No significant differences in the parasitic infection rate by sex was noticed although male group showed lower infection rate than female group. However the incidence of C. sinensis, M. yokogawai and Taenia spp. was twice as much in female group as in male group. 4) No difference in the infection rate by age was found although E. vermicularis positive rate was highest in "0~9 years group" by 2.1% and C. sinensis infection rate was higher in over "30~39 years group". The parasitic infection rate of the present study was significantly lower than those of previous reports in Seoul area and other provinces.

A combined syrup preparation of pyrantel pamoate and oxantel pamoate containing 50mg/ml of respective anthelminthics was evaluated on the efficacy to treat the human intestinal nematodes. Total 24 cases were treated with oral administration of above preparation 10 mg/kg body weight by single dose. The results were summarized as follows: 1. Out of 21 cases of Ascaris lumbricoides infection, 19 (90.5%) turned to be egg negative on 21 days after treatment and egg-reduction rate was 99.7%. 2. 17 cases out of 19 cases infected with Trichocephalus trichiurus were egg negative after treatment (84.2%) and egg reduction rate was 60.6%. 3. As for Ancylostoma duodenale infection, egg negative conversion rate was 88.9% and egg reduction rate was 98.1% by single oral administration among 9 infected cases. 4. In Enterobius vermicularis infection, all of 17 cases gave negative anal swab on 21th day after the treatment. From the above results, it was assumed that the anthelminthic activities of pyrantel pamoate and oxantel pamoate were not potentiated by the mixture of two kinds of drugs but showed simple additive effect.
