The present study was performed to observe tegumental ultrastructure of Echinoparyphium recurvatum according to developmental stages. Worms (1, 3, 5 and 15-day old) were recovered from chicks experimentally infected with metacercariae from Radix auricularia coreana. One-day old worms were elongated and ventrally concave, and covered with peg-like tegumental spines except the adjecent areas of the head crown and excretory pore. Type I sensory papillae were distributed on the lip of the oral sucker, and grouped ciliated papillae were around the oral sucker. Peg-like tegumental spines were densely distributed on the anterior surface of the ventral sucker level. The ventral sucker had an aspinous tegument and no sensory papillae. Tegumental spines on the posterior surface of the ventral sucker level were sparsely distributed and disappeared posteriorly. In 3 and 5-day old worms, the tegument around the oral sucker was aspinose and wrinkled concentrically. The ventral sucker had a wrinkled tegument and many bulbous papillae. Type I sensory papillae were distributed between the bulbous papillae. Tegumental spines were spade-shaped with a terminal tip. A total of 45 collar spines including 4 end group ones on both ventral corners was alternately arranged in 2 rows. The 15-day old worms were very stout and their tegumental spines were tongue-shaped without a terminal tip. From the above results, it is confirmed that the surface ultrastructure of E. recurvatum was generally similar to that of other echinostomatid flukes. However, some features, i.e., morphological change of tegumental spines and appearence of sensory papillae on the ventral sucker according to development, and number, shape and arrangement of collar spines, were characteristic, which may be of taxonomic and bioecological significance.

A retrospective review was performed in 33 knees of 30 patients who had undergone arthroscopic debridement for degenerative osteoarthritis of the knee. The mean age of the patients at operation was 55 years and the mean follow-up after operation was 15 months. We divided the knec:s into 2 groups; meniscectomy group (23 knees) and non-meniscectomy group (10 knees). The preoperative radiographic findings were divided into 3 groups according to the classification systern by Lotke et al. The postoperative results were evaluated using the nine-point scale by Baumgaertner et al. Our study was conducted to: 1) assess the overall efficacy of arthroscopic debridement, 2) compare the results between the. Meniscectomy group and nonmeniscectomy group, and 3) identify the relationship between the preoperative radiographic findings and out- come at the final follow-up time. Overall excellent or good results were ac.hieved in 22 knees (67%) and the preoperative radiographic findings correlated with the outcome at the final follow-up time. But the results in the meniscectomy and non-meniscectomy poups showed no significant differences statistically. We believe that arthroscopic debridement is an effective option of treatments for mild I:o moderate degenerative arthritis of the knee after failure of conservative measures.

Primary malignant melanornn of the vagina is rare, with only about 130 reported cases worldwide. They presumably arise from melanocytes that are present in the vagina in 3% of normal wornen. Vaginal melanoma accounts for less than 1% of melanomas and less than 3% of primary malignant tumors of the vagina. Most of patients complain vaginal bleeding, vaginal discharge, foreign body sensation in order. The best treatment of vaginal melanoma rernains eni.gmatic, Many authors indicate that radical surgery may be the pcferred approach and the number of reported cases treated with radical surgery is increasing. But other author comment that no significant change in survival is apparent with radical surgery. Overall prognosis is poor as most patients have deeply penetrating lesions at the time of diagnosis. Recently, not only the effort to increase the survival rate but the quality of life including sexual function after treatment is becoming an important issue about treatment ot cancer patients. We experienced a case of primary malignant melanoma of the vagina treated with radical surgery and restored the sexual function by vulvovaginal reconstruction using gracilis myocutaneous flap. So we report this case with brief literature review.

Symphyseal injury is increasing in number together with today's speed of development of car industry in Korea. However, this injury is not common in practice. Some authors reported that symphyseal injury is only 4 to 6% of all pelvic fractures. Symphysis pubis has characteristicsl anatomy to maintain mechanical integrity of the pe1vis with circumferential ligament. The pelvis is a ring structure with strong ligaments. This support include the symphysis pubis, the anterior and posterior sacroiliac ligaments, and the strong sacrotuberous ligaments. According to Peltier(1964), when symphysis is separated more than 1.0cm, pubic instability will be developed. However, Wild(1982) reported that pelvic instability develops when separation of the symphysis exceeds more than 2.5cm. Tile(1984) reported that anterior pubic rami acts as a strut to prevent anterior collapse of the pelvic ring during weight bearing. However, in the presence of intact posterior structures, it gives little effect on pelvic stability. In addition to trauma, pelvic instability develops congenitally or by pregnancy. During pregnancy, pregnancy-related hormones relsx the ligameritous stuctures of the pelvic girdle. In most instances, the major pelvic ring returns to normal when the effect of the relaxin hormones disappear. However, in rare instances, a major symphysis disruption may continuously persist. To evaluste the trauma-induced separation of the symphysis pubis, we analyzed the 19 cases with 15 months follow-up on an average, who were treated at the Orthopaedic Department, Kang-Nam St. Marys Hospital, from June 1981 to June 1986. The results were as follows 1. Among 19 cases, 9 cases(47.4%) were male, 10 cases(52.6%) were female. And average age of the patients was 30.2 years. 2. The main cause of the fracture was traffic accident in 18 out of 19 cases. 3. In cases of symphyseal separation more than 3.4cm, fracture-separation of both sacroiliac joint was certainly occured. However, in cases with separation more than 2.2cm, unilalateral fracture-dislocation of sacroiliac joint occurred. 4. Open reduction and interal fixatiopn including external fixation was performed in 9 og cases. As an indication of surgery, separation of the symphysis, which exceeds more than 2.2cm and which associated (1) with sacroiliac fracture-dislocation, (2) failed conservative treatment, and (3) when simultaneously emergency urological operation is indicated.
