OBJECTIVE: To show the value of rotating chair test (ROT) as an adjunct to the conventional electronystagmography (ENG) examination including caloric test for the diagnosis of vestibular lesions. BACKGROUND: Since caloric stimulatim is regarded as a very low frequency (0. 003Hz) test, it is desirable to test the function of horizontal semicircula canals by stimulating with faster frequencies. Baloh et al. (1984a) described that lesions ofdifferentiated by ROT. Leigh and Zee(1991) told that ROT can give more accurate and reproducible results than do caloric tests. METHOD: 30 patients who suffered from vertigo with either peripheral or central pathology were given computerized ENG and ROT. We discuss the representative examples of our initial experience with ROT. RESULTS: 1.In eight patients with known peripheral pathology, low-frequency phase deficits, asymmetry toward the lesim side and VOR suppression by gazefixation were seen during ROT. With bilateral peripheral vetibular disease, the ROT could identify remaining vestibular function at higher frequencies. 2. Seven patients with lesions of central vestibular structure showed abnormalities of saccades and pursuit during ENG and failure of VOR suppression by gaze fixation during ROT. 3. Out of 15 patients whose lesions could not be localized distinctly after caloric test, four patients were suggested to have central pathology. CONCLUSION: ROT can be a useful method to study the vestibular abnonnahties and an adjunct to the conventional ENG test.

As a series of systematic classification of paramphistomes, in the first step, paramphistomes in the rumen and reticulum were collected on 170 Korean cattles (2-3 years age, male) slaughtered at Jeonju abattoir from July 1984 to September 1985 and were classified by means of morphology of the worms. Afterwards, the karyotype of Paramphistomum explanatum (Creplin, 1849) which is the common in Korean cattle was detected by means of modified air-drying method from testis cells of the worm. The following is a brief summary of the leading facts gained through the experiment. Most of the cattle slaughtered at the abattoir were infected with paramphistomes. The 5 species of the worms were detected on 170 Korean cattle and the worm burden per head was from 2 to 784 (on the average 170) worms, 120(70.59 percent) heads out of them involving 2-100 worms. In 28,900 individuals of paramphistomes obtained on 170 Korean cattle, appearance rates of various worms were as follows : 49.74 percent in P. explanatum, 48.08 percent in P. cervi, 0.98 percent in Orthocoelium orthocoelium, 0.89 percent in Fischoederius cobboldi and 0.14 percent in Cotylophoron cotylophorum. The chromosome number of 620 P. explanatum in the haploid and diploid cells was n=9 and 2n=18, and abundant cells in meiotic division were observed; 1,420 haploid and 38 diploid cells were reliable. Nine pairs of mitotic chromosomes were homologous and the chromosomes were composed of five medium-sized metacentrics (m), subtelocentrics (st) or submetacentrics (sm)and four small-sized subtelocentrics (st) or submetacentrics (sm), while meiotic metaphase chromosomes were composed of five medium and four small-sized. The haploid of the testis cells showed C-band in the centromeric region from 8 of them, whereas the remaining chromosome No. 5 included heterochromatin on the tip region, and chromosomes No. 3 and No. 7 showed a remarkable C-band distinguished from other chromosomes.

This comparative study was undertaken to investigate the position of the hyoid bone in unilateral cleft lip and palate individuals. The materials for this study consisted of 35 subjects with surgically repaired unilateral cleft lip and palate (25 males, 10 females) and 40 subjects with normal facial morphology (20 males, 20 females). Cephalometric measurements of unilateral cleft and palate individuals were compared with those of non-cleft individuals. The conclusions of this study were obtained as follows: 1. To the anterior cranial base, the hyoid bone in unilateral cleft lip and palate individuals was located downward as compared with non-cleft individuals. 2. To the mandible, the hyoid bone in unilateral cleft lip and palate individuals was located backward as compared with non-cleft individuals. 3. The distance between the dorsum of the tongue and the inferior border of the hard palate in unilateral cleft lip and palate individuals was longer than that in non-cleft individuals. 4. Unilateral cleft lip and palate individuals showed no significant difference in the distance between the hyoid bone and the dorum of the tongue as compared with non-cleft individuals.

In order to clarify infestation pattern for the encysted larvae of digenetic trematodes from fresh-water fishes, this survey was carried out from March to September, 1983. A total of 380 fishes of 32 species were collected with netting at the three reaches, upper, middle and lower in Mangyeong riverside area. After the fishes were dissected into small scraps, they were pressed under cover glass and examined for the presence of those of digenetic trematodes with a microscope. The results obtained were as follows: Out of a total of 380 fishes inspected, 320 fishes (84 percent) from 31 species were found positive with digenetic trematode metacercariae; more than 10 species of the metacercariae were detected in Pseudorasbora parva; Gnathopogon majimae, Microphysogobio yaluensis, Cultriculus eigenmanni and Gnathopogon coreanus (more than 8 species); Aphyocypris chinensis(8 species) and etc. respectively. Clonorchis sinensis metacercariae were found positive from 93 fishes (25 percent) from 12 species detection rates in other species of digenetic trematode metacercariae from various fishes were; Exorchis oviformis, 261 fishes (57 percent) from 28 species; Cyathocotyle orientalis, 47 fishes (12 percent) from 12 species; Metorchis orientalis, 21 fishes (6 percent) from 12 species; Metagonimus yokogawai, 164 fishes (43 percent) from 26 species; Pseudexorchis major, 71 fishes (19 percent) from 18 species; Metacercaria hasegawai, 77 fishes (20 percent) from 25 species; Centrocestus armatus, 24 fishes (6 percent) from 7 species; Echinochasmus japonicus, 2 fishes (0.5 percent) from 2 species, and unidentified species, 34 fishes (9 percent) from 15 species respectively. The sums of average number of the encysted larvae of all species found in fish body/gram showed 83 in P. parva, Cobitis taenia (74.2), A. chinensis (28.5), Pseudoperilampus uyekii (26.6), G. majimae (19.6) and etc. respectively and the average peak number of each metacercaria in fish body/gram showed 21.7 C. sinensis, 24 E. oviformis , 15.3 M. orientalis and 6.1 E. japonicus in P. parva ; 42.7 C. orientalis and 25.1 M. yokogawai in C. taenia; 8.3 C. armatus and 8.3 M. hasegawai in P. uyekii; 6.3 P. major in Carassius carassius, and 2.9 unidentified species in G. majimae respectively.
