The author has recently experienced two cases of cysticercosis whish occurred under the superior bulbar subconjunctiva and the caruncle. These cases were not associated with any other systemic lesions elsewhere in the body. The cysts were surgically removed and the microscopic examination confirmed a well preserved cysticercus cellulosae. According to the previous reports, the cysticercosis occurs frequently in the ocular region. In the ocular region, the subretina and the vitreous cavity are the predominating areas. The author experienced subconjunctival cysticercosis in the eye where it has rarely been reported. The ocular cysticercosis is known as a very rare case in Korea. A brief medical history of cases and a review of the related reports are presented.

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

We investigated seven cases of intraocular cysticercosis: 4 subretinal in the macular region, 1 subretinal just above the optic disc and 2 in the vitreous cavity. Preoperative diagnosis was confirmed in all cases by observing the characteristic movement of the cysticercus larva. Trans-scleral extraction of the cysticercus was performed and resulted in improvement of vision in two cases and preservation of the preoperative vision in the other cases. We reviewed the medical histories, preoperative evaluation of the status of the vitreous and the retina, and the procedures of the operation.

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.

The authors have recently experienced with a five years old female patient who had a cysticercosis under the superio-nasal bulbar conjunctiva. The case was not associated with any other systemic lesions elsewhere in the body. The cyst was surgically removed and the microscopic examination confirmed a well preserved cysticercus cellulosae. According to the previous reports, the cysticercosis occurs frequently in the ocular region. Although ocular cysticercosis is common, subconjunctival cysticercosis rarely been reported in Korea. A brief medical history of case and a review of the related reports are presented.

An electron microscopic study was performed to know the basic tegumental structure of Cysticercus cellulosae. The scolex and bladder portions of cysticerci (human and porcine strains) were prepared for transmission and scanning electron microscopy by conventional procedures. In general, the tegument of C. cellulosae showed the basic ultrastructure of cestode tegument on electron micrographs. The teguments of both scolex and bladder portions consisted of such components i.e., an outer vesicular layer with numerous microtriches and inner fibrous layer. Below the fibrous layer, there were layers of muscle bundles and tegumental cells. The microtriches which covered the surface of cysticercus revealed two distinctly different shapes. The characteristic bladder-like, elongated pyramid shaped 'tetrahedral form' was observed on the surface of the scolex portion, whereas the elongated cylindrical 'filamentous form' was distributed on the surface of bladder portion. In spite of the difference of isolated host and location, the cysticerci showed the same result. But dimensional variations of the tegument according to topography of the worm were observed. The possibility of application in making differential diagnosis from other larval cestodes and possible functions of this larval tegument were discussed.

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

The Authors recently experienced with a 11 years old female patient who had a cysticercus in her left inferior rectus muscle. Under the diagnosis of a conjunctival cyst, a surgical intervention was carried out. The microscopic studies revealed that as a cysticercus cellulosae. The post-operative outcomes are uneventful and the ocular functions are satisfactory, visual acuity and ocular motility as well.

An acephalic budding Cysticercus of 1.2 cm long was removed surgically at the abdominal wall of a Korean man. The worm revealed abnormal buds on the bladder wall and absence of suckers and hooklets in the scolex body. The buds were of two histologic types; branching bud covered with normal tegumentum and with subtegumental cells of normal density, and buds of proliferated subtegumental cells with lacunae formation. On the bases of the morphologic features, it was identified as a racemose cysticercus. This case confirms that its extracranial location is possible.
