One of the most common symptoms in gynecologic disorders is an abnormal utirine bleeding, of which dysfuncyional uterine bleeding (DUB) is frequently encountered. DUB is defined as an endocrinologic imbalance of the axis of hypothalamus-pituitary-ovary-endometrium without organic diseases such as a neoplasm, and inflammation, a pregnancy, a trauma, Although the correct diagnosis of DUB depends on various assessements such as a menstrual cycle, basal body temperature, endocrine assay, vaginal cytology and endometrial histology, in many circumstances pathologist have only the endometrial histology with trivial clinical information to make a diagnosis. Therefore, the present study was aimed at assessing the pattern of the endometrium as precisely as possible. The histologic pattern was classified according to the Handrickson and kempson classification (1980). The authors also attempted to correlate the non-neoplastic metaplasia with the endometrial histology. The material consisted of 447 cases of endometrial curettage specimens diagnosed clinically as DUB during recent 4 years. The histologic examination was carried out through the routine formalin fixed-paraffin embedding method, followed by hematoxylin-eosin staining in routine and other special staining as required. The following results were obtained; 1) The pattern of the endometrium in DUB was predominently the proliferative type (239 cases, 65.55%). Of these 293 cases, 144 were of the abnormal proliferatrive phase, and particulary most were the disordered proliferative phase. The remaining 154 cases (34.45%) were found to have secretory endometrium, of which 50 cases belonged to the abnormal secretory type. Most of the cases shewing abnormal secretory patterns appeared dyssynchronous or underdeveloped. 2) Of the 361 patients with DUB for whom the clinical records were available, 197 (54.57%) were non-ovulatory and 118 (32.69%) were ovulatory. 3) Non-neoplasic metaplasia was found in 87 cases, of which ciliiated and papillary types were most common. The endometrium was of the proliferative phase in 73.56% of the cases with metaplasia, and the disordered proliferative pattern showed a particular correlation with the metaplasia (44 cases). 4) Among 63 postmenopausal DUB patients, 52 (82.53%) appeared to have the proliferative endometrium, and in particular 23 (36.51%) had the disordered proliferative endometrium.

Unilateral absence of the articular process at a lumbar vertebra is a rare anomaly. The etiology of the congenital absence of articular process is not precisely determined yet, but it was explained as some of the possible embryologic bases. Absence of the articular process at the level of L5-Sl have been reported a few, but anomaly above L4 is rare. We are reporting a case of absence of articular process at the level of the 4th lumbar vertebra.

Most patients who have spondylolysis dont's need surgical treatment. However, for the patients who have no response to conservative treatment, surgical treatment may be indicated. In 1970, Buck reported the operative technique that the used two screws between the pars defect and lamina followed by bone graft. In patients who have spondyloysis, pain in the back seems to be due to instability and irritation of nerve root by the abnormal motion of the loose neural arch and granulation tissue. For period of 7 years from May, 1984 to March, 1991, twelve patients with spondyloysis who had no response to conservative treatment were treated with Buck's operation and were analyzed. Following results were obtained: 1. The age of the patients was 24 years in average ranging from 14 to 40 years. 2. The level of the lesion was L5 in 10 cases, L4 in 2 cases. 3. Preoperative clinical feature included low back pain in 12 cases, refered pain in 2 cases. 4. Clinical sympotoms were improved in 83%, and the follow up result of the operation: excellent 16.7%, good 66.6% and poor 16.7%.

Recent development in the polymerase chain reaction( PCR) technology has brought an extraordinary opportunity for the rapid detection of Mycobacterium tuberculosis in clinical specimens for the diagnosis of tuberculosis. This study was initiated to compare the PCR results with those obtained by culture on Ogawa medium. A total of 18 urine samples from patients suspected having tuberculosis were tested by PCR using the primer: P1(5'-AGC-ACG-GCG-ATT-TGG-AGT-CG-3')andP2 (5'-ATC-GTT-TTC-GGC-GGT-ATC-TG-3'). Of 5 culture positive samples, 3 showed the 320 bp DNA products in PCR and 2 were negative. Besides, 3 of 13 culture negative samples also showed positive results in PCR. In conclusion, the PCR easily detected M.tuberculosis in smear-positive samples. The PCR could detect the presence of M.tuberculosis when the samples were culture negative. Therefore, the PCR was probably more sensitive than culture. Because of the extreme sensitivity of PCR, one would expect to be able to detect organism that are present in low numbers and those that are nonviable. However, the PCR method could miss the culture proved M.tuberculosis. The PCR method looks promising for the rapid and specific laboratory diagnosis of tuberculosis.

We analyzed 177 diabetic patients(80 males, 97 females) with the nerve con duction study (NCS) performed twice or more at the interval of more than one year in Severance Hospital from Jan 1, 1984 through Dec 31, 1994. We conclude as follows: 1)The NCS follow-ups showed that diabetic polyneuropathy was getting worsened electrophysiologically as time goes by. 2)The NCS revealed that the earlier change was noticed on the distal portion of sensory nerve fiber, though diabetes was known to cause a damage to both sensory and motor nerve fibes. 3)Considering that the NCS follow-ups revealed earlier and more marked changes in amplitude than in nerve conduction velocity, axonal degeneration seems to be more responsible for the pathogenesis of diabetic polyneuropathy rather than segmental demyelination.
