The present study was undertaken to evaluate the prevalence rate of Taenia spp. infection and distribution of taeniasis caused by T. solium among Koreans in several localities in Korea during the period from 1977 to 1980. A total of 1,946 stool specimens collected from students and inhabitants of Chungcheong Bug Do and Gyeongsang Nam Do were examined by cellophane thick smear method. Among them, 40 persons were detected as Taenia egg positive cases. The overall positive rate of Taenia spp. shows 2.1 percent. The prevalence rate of male (2.3 percent) is relatively higher than that of female (1.4 percent). In order to observe the distribution of Taenia solium infection, the whole worms or a part of proglottids of Taenia spp. were collected from the stools of egg positive cases by normal defecation or anthelmintic treatment. For the species identification, expelled proglottids were examined microscopically by the number of branches of the uterus, presence of a vaginal sphincter or the accessory ovarian lobe etc. Among 199 egg detected cases in this study 59 (39.1 percent) out of 151 cases in Seoul, 12(40.0 percent) of 30 cases in Gyeongsang Nam Do and 2 (25.0 percent) from 8 taeniasis cases in Cheju Do were infected with T. solium. But none of T. solium infection was found from 10 egg positive cases in Chungcheong Bug Do. As a whole, the composition of species shows 36.7 per cent of T. solium infection and 55.8 percent of T. saginata infection, and in 7.5 per cent the species were not identified.

Molecular examination on Taenia solium cysticercus isolated from Vietnamses patients in Bac ninh province. Total DNA was extracted. PCR were performed and the nucleotide sequences were developed. Nucleotide sequences and amino acids of cob gene fraction was confronted to some species of Taenia isolated from China, Taiwan. The result confirmed that cysticercus isolated from Vietnamese is Taenia solium

Studty was conducted on 42 patients (32 males and 10 females, aged 14-55 years old) with taenia soluincyst in brain. The cyst was common at the age 20-49 years old, female 23.81% and male 76.19%. There was a diversity of nervous syndromes in both 2 hemispheres of brain, the most were intern-cerebral high pressure 95.2% and epilepsy 54.74%. Active forms of cyst accounted for 73.81%, needed for treating CT images of skull and brain showed a dispersion of the cyst in both 2 hemispheres of brain, consisted with the clinical symptoms.

b cytochrome oxydase gene fragment of the mitochondric geneme includes 652 nucleotides and aminoacide of taenia solium isolated from Vietnamese [symbolized as TsoN (VN)] was received by PCR reaction, purified, cloning and expressed in sequence. Results were compared with those of corresponding sequence of some genera of Taenia solium in China (T. saginata) in Taiwan (Taeniaasiatica) and in Viet Nam. Cysticercoid larve of Taenia solium isolated from Vietnamese was similar with that isolated from pig in Viet Nam and China, but there are high difference between the genera T. saginata (in China) and T. asiatica (in Taiwan and Viet Nam). The analysis determinated various varieties of eysticercoid larve as Taenia sodium’s larva. This is the first determination of this genus in Viet Nam

A complete but abnormal form of Taenia worm was obtained from an 18-year-old male student in Cheju Island, Korea, which has been known as a heavy endemic area of Taenia saginata and few of T. solium. There was an apical hookless eminence in the scolex, longitudinal white line along the middle portion of entire strobila, double genital pores and several lateral buddings from the strobila. It was considered an abnormal form of Taenia species, probably T. saginata.

The survey was carried out between June - December 2002 and May - October 2003 in the different sites of Ha Noi. 138.298 pigs and 9.755 cattle were inspected. One of the 138.298 inspected pigs was found to be infected with Teania solium larva (0.000723%). No one of 9.755 inspected cattle was found to be infected. The survey was also carried out in the pork shops in five districts of Ha Noi city: Dang Tran Con (Dong Da district), North Thanh Xuan (Thanh Xuan district), Thanh Cong (Ba Dinh district), Van Dien (Thanh Tri district) and Phung Khoang (Tu Liem district). In 5.570 times of inspection in the pork shops, only one sample (0.018%) was found to be infected with Teania solium larva. This infected case was found from 1.305 samples (0.08%) collected in the Thanh Cong market. None of 4.265 inspected samples was positive with Teania solium. Also none of the samples collected from meat of cows and buffalo sold in 1.557 shops was found positive

Previous paleoparasitological studies of Joseon specimens established that the prevalence of Taenia infection was not much different from that of the early 20th century Korean population. As many of taeniases originally diagnosed as Taenia saginata in South Korea were revealed to be actually Taenia asiatica, which share a common intermediate host with T. solium (the pig), Joseon people must have ingested raw pork frequently. However, the current examination of extant Joseon documents revealed that the population ate significant amounts of beef even if the beef ban was enforced; and pork was not consumed as much as we thought. Considering the meat consumption pattern at that time, Joseon people should have been infected by T. saginata more frequently than T. asiatica. This may suggest a low prevalence of T. saginata metacestodes in cattle compared to that of T. asiatica metacestodes in pigs, possibly due to the traditional way of rearing pigs (using human feces). This letter gives us a chance to reconsider the existing preconception about parasitic infections in Korean history though we are still hard to accurately estimate the historical patterns of taeniases at this stage.

Ten cases infected with Taenia saginata were treated with Bithionol, 2, 2' thiobis (4,6-dichlorophenol) which is well known as an excellent anthelminthhic against paragonimiasis and their follow-up studies were carried on within 3 to 12 months after treatment. Bithionol, 50 mg dose per kg of body weight was divided into two equal dose and administered orally in 30 minutes intervals. Three hours later, this was followed with a sodium sulfate or magnesium sulfate purge. The strobilas without scolices were found in the stools after the medication and the follow-up studies have shown the complete deworming in all cases. It is well tolerated, toxic effects being uncommon and when present, limited to mild gastro-intestinal disturbances.

The phamacological and anthelmintic action of Lysimachia clethroides were examined. Upon examining the action of water, ether, alcohol and acetone extrcts of the root on smooth muscle, it was found that the active principle was weakened by heating. Water and ether extracts inhibited the dehydrogenase of the worm. In 50 percent of 8 areas studied, Taenia were completely eliminated with 2.5-4.0 gm doses of the ether extracts, and no toxic effect was observed by the administration of the above-mentioned doses.

From 1960 through 1965, 39 cases with epileptic seizure caused by the Cystricercus cellulosae were experienced at Kaejong Mental Hospital, Okku-Gun, Chollapukdo province. The present study was carried on at the area of Chollapukdo province where Cysticercus cellulosae cases were frequently reported. Thrity-nine Cystricercus cellulosae cases(35 male and 4 female) with epileptic seizure visited Kaejong Mental Hospital . Okku-Gun, Chollapukdo during the years of 1960-1965 from various Gun(county): Okku-Gun 13, Kimje-Gun 7, and Soonchang-Gun 6. The high incidence was found at the age group of 20-49 years and the distribution of 214 subcutaneous nodules were as follows: Trunk 56.6 percent, upper extremities 26.6 percent, head and neck 9.3 percent, lower extremities 7.5 percent. According to the address of above 39 cases, taenia infestation of the inhabitants in the area was examined by questionaire form. Plain rural area (Maryong-Ri, Okku-Gun); Among 803 persons interviewed, 4.0 percent or 32 complained the output of Taenia segments. The male group showed higher incidence (6.4 percent) than the female(1.5 percent) . The highest incidence was observed at the age group of 30-39 years. Most of the inhabitants of the area had the eating habit of raw beef and pork. Mountainous rural area(Bok-Heung-Myun, Soonchang-Gun); Among 542 persons interviewed, 33 or 6.1 percent complained Taenia infection. The higher incidence was observed in the male group(8.7 percent) than in the female group(3.1 percent) , and also at the age group of 20-49 years. They had eating habit of raw beef and pork. The species of adult worm were identified by morphological examination. Totally 36 adult worms(Taenia saginata 21, T. solium 15) were obtained from 26 cases, and it was experienced that 5 T. solium were eliminated from one person.
