OBJECTIVE: To evaluate luteinizing hormone(LH) in patients with infertility and recurrent spontaneous abortion. MATERIAL AND METHOD: LH was tested by solid phase immunoradiometric assay based on monoclonal and polyclonal anti-LH antibodies. RESULTS: Of 100 infertile patients, the number of less than 5 mIU/ml, 5~10 mIU/ml, greater than 10 mIU/ml in LH level was 67(67%), 22(22%), 11(11%), respectively. Of 100 patients with recurrent spontaneous abortion, the number of less than 5 mIU/ml, 5~10 mIU/ml, greater than 10 mIU/ml in LH level was 79(79%), 18(18%), 3(3%), respectively. There was a significant difference between patients with infertility and recurrent spontaneous abortion only in the group with LH level greater than 10 mIU/ml(p=0.325). CONCLUSIONS: High LH in the follicular phase is known to decrease pregnancy rate and increase abortion rate. But in this study the incidence of high LH in patients with recurrent spontaneous abortion was low. On the contrary, there was a significant increase of LH in infertile patients. So recurrent spontaneous abortion does not seem to be related to high LH level.

Psoriasis and eczematous dermatitis are two major different inflarnmtory dermatitis but differential diagnosis is sometimes difficult by histologic patterns. The object of this study is to find out whether there are any differences in the expressions of proliferation related pntein between psoriasis and eczematous dermatitis by chronological evaluation on the proliferating cell nuclear antigen(PCNA) and epidermal growth factor receptor(EGFR). The detections of PCNA and EGFR were done by immunohistoc.ienical methods(alkaline phosphatase anti-alkaline phosphatase method with new fuchsin substrated usir g respective polyclonal antibod ies in the paraffin embedded tissue from psoriasis(21 cases) and eczomtous dermatitis(26 cases). The labelling indeces of PCNA were 2.4+0.9% in normal. Indece; were 27.3+2.9% in acute, 20.7+ 3.7% in chronic psoriasis, while 12.4+5.6% in acute and 21.8% 5.0% in chronic eczematous dermtitis. The expressions of EGFR were very weak in normal, and increased in acute psoriasis and chronic eczematous dermatitiy. Our immunohistochemical results of PCNA and EGFR suggest that activated proliferation is rather pronounced in acute psoriasis and chronic eczemat.ous dermatitis, thouh proliferative activity is more marked in psoriasis.

Argon laser trabeculoplasty(ALT) is commonly used in the treatment of uncontrolled open angle glaucoma. The authors retrospectively reviewed the efficacy of ALT in 52 patients(57 eyes) with primary open angle glaucoma. The mean follow-up was 28 months(range 2-48 months). The decrease in intraocular pressure 10P) was 10.1 +/- 3.5 mmHg at 1 month, 8.2 +/- 2.8 mmHg at 1 year, 6.2 +/- 5.1 mmHg at 2 years and 51% at 3 years. Failure was most common in the first 6 months after treatment(29%) and thereafter failure occurred at a rate of 5% to 15% per year. The sex and age of patients had no significant effect on success rate. The success rate was high in the patients with baseline IOP of 26 to 30 mmHg. A mild iritis in all cases, transient rise in IOP, peripheral anterior synechia and microscopic hyphema were noted as early complications of ALT.

A survey for nematode and cestode parasites of rodents in Korea has been carried out at the areas of Chulwon, Kumwha, Pochon, Paju and Chungpyong, Kyunggi-Do. A total of 300 rodents of seven species was examined, comprising of 219 A. agrarius, 33 R. norvegicus, 8 R. alexandrinus, 14 Mus musculus yamashinai, Microtus fortis pellceus, 21 Crocidura russula and a Cricetulus trition nester. The following fifteen species belonging to thirteen genera were identified: NEMATODA: Heterakis spumosa, Syphacia obvelata, Nippostrongylus muris, Protospirura muris, Capillaria hepatica, Capillaria sp., Heligmosomum sp., Heligmosomoides sp., Rictularia sp. and Gongylonema sp. CESTODA: Hymenolepis nana, Hymenolepis diminuta, Raillietina coreensis, Paranoplocephala sp. and Cysticercus fasciolaris(the larva of Taenia taeniaeformis).

For orthodontic tooth movement, optimal orthodontic force should be maintained without periodontal breakdown and alveolar bone should be remodeled physiologically. Therefore, To obtain proper occlusion through tooth movement within alveolar bone, we should know the biomechanics of teeth and supporting tissues. The present study was performed to observe histologic changes of periodontal tissue immediately after application of orthodontic force and during the retention period in growing young adult dogs. In this study, experimental group contained between mandibular left canie and 1st molar and control group contained contralateral teeth of same animal. The .018"x.22" stainless steel closed coil spring(Dentaurum Co.) was ligated on the experimental teeth at initial 200gm-force from mandibular canine to 1st molar. The animals(4 to 6 months aged young adult dogs) were sacrificed on 0, 14, 28 days after the finish of appliance activation, and then tissue samples were divided into hematoxylin-eosin(HE) staining section, ground section, alkaline phosphatase(ALP) staining section, and tartrate-resistant acid phosphatase(TRAP) staining section. Thereafter, the preparations were examined under light microsopy. The following results were obtained: 1. Immediately after the finish of appliance activation, the periodontal space was increased in tension side, but decreased in pressure side compared to that of control. The hyalinized zone was also observed in the periodontium. 2. After the 14-day retention, periodontal space was decreased in tension side and slightly increased in pressure side compared to that of immediately after the finish of appliance activation. The hyalinized zone was repaired and a few osteoblasts showing slightly new bone formation were seen. Osteoblasts were scarcely observed along the alveolar bone. 3. After the 28-day retention, the periodontal fibers are normally repaired. A lot of TRAP(+) osteoclasts and increased alveolar bone resorption were observed in pressure side, and AP(+) osteoblast and increased new bone formation were observed in tension side.

Despite the large amount of adipose tissue in bone marrow, intraosseous lipoma is a very rare tumor. Since th first report by Cornil and Renvier in 1868 for a lipoma in the diaphysis of the femur, many cases of intraosseous lipomas of the limbs have been reported. For intraosseous lipoma, Dahlin reported an overall incidence of one per 1,000 bone tumors. Child reported the first case of intraosseous lipoma in the calcaneus. In Korea, a intraosseous lipoma in the fibula was reported only. We reported a case of intraosseous lipoma in the calcaneus.

MRI has proved to be very reliable in evaluating the menisci and cruciate ligaments. On MRI, several diagnostic criteria of ruptured ACL were reported. Boeree and Ackyroyd reported that when the ACL is ruptured the PCL may appear to be curled up or sigmoid. But these morphologic changes may be shown in the normal ACL, so the quantitative analysis of these morphologic changes in considered as a way to increase the diagnostic sensitivity. We have used 1.0 tesla MRI scanner(SIMENS W. Germany) with a surface coil. We compared two groups of patients; a ruptured ACL group(16 patients) in which had indicated and arthroscopy confirmed rupture of the ACL and control group(46 patients), in which had shown the ACL to be entirely normal. At first, we made a line(basal line) between the femoral attachment and tibial attachment of the PCL and decided the point(apex) which was located far distant from the line. And we made a line(A line) between the femoral attachment and apex of the PCL, another line(B line) between the tibial attachment and apex of the PCL. We divided the basal line into the four areas. We measured the each angle between basal line and A line(angle a), between basal line and B line(angle b). And we measured the entire length of basal line, each height of the PCL previously divided point of the basal line(H1, H2, H3) and the apex of the PCL on the basal line. We compared the control group and ruptured ACL group by t-test from the measured factors angle a, angle b, H1, H2, H3, H4, and length of basal line. We studied factors which were able to decide whether the ACL was ruptured or not in MRI finding by logistic regression. 1. H1, the distance from the basal line to the PCL at 1/4 point on the basal line, were 5.7±1.6 mm in ruptured ACL group, 4.7±1.3 mm in control group, so there was statistically significant increase in ruptured ACL group. 2. The angle a were 56.0±14.4° in ruptured ACL group, 39.7±10.1° in control group, so there was statistically significant increase in ruptured ACL group. 3. From the measured factors angle a was able to decide whether the ACL was ruptured or not in MRI and the slope of angle a in logistic regression was 0.1. In conclusion, when the apex of the PCL is located at proximal 1/4 of the PCL and PCL and greater curve, above signs will be considered to be a sign of ruptured ACL in MRI.
