BACKGROUND: Uterine leiomyoma is the most common pelvic tumor, occurring in 20-25% of women in reproductive age. Gonadotropin releasing hormone agonist (GnRHa) has been reognized as a temporary medical management for this disorder. The etiology of these tumors is unknown but it has been shown that the insulin-like growth factors (IGF-I, IGF-II) are promoters of growth in nongynecologic tumors. Several recent studies have suggested the possible role of IGFs in human leiomyoma growth. The IGF binding proteins (IGFBPs) are believed to modulate actions of IGF and to have IGF-independent actions. The purpose of this study was to evaluate the type of IGF and IGFBP which may be involved in leiomyoma growth and to investigate a possible IGF related mechanism of action of GnRHa. METHOD: The IGFs and IGFBPs were measured by double antibody radioimmunoassay, western ligand blot and immunoprecipitation in the tissue cytosols of normal uterine myometria (n=15), nontumorous myometria adjacent to a leiomyoma and leiomyoma from patients nontreated (n=15) and treated (n=10) with GnRHa. RESULTS: The mean IGF-I and IGF-II level were significantly higher in leiomyoma from untreated patients than in the adjacent myometrium and normal myometrium but no significant differences in these IGF levels between normal myometrium and adjacent myometrium were noted. The IGFBP-2, IGFBP-3 and 26kDa IGFBP were detected variably but IGFBP-4 was consistently present in all tissues. There were no significant differences in the relative intensity for IGFBP-4 and the frequency of IGFBPs between leiomyoma, adjacent myometrium and normal myometrium from untreated patients. The IGF-I, IGF-II levels and the relative intensity of IGFBP-4 in leiomyoma from GnRHa-treated patients were significantly lower than those in untreated patients, but these levels in the adjacent myometrium were comparable. The frequency of each IGFBP in leiomyoma and the adjacent myornetrium from GnRHa-treated patients did not significantly differ from untreated patients. CONCLUSION: Both IGF-I and IGF-II are involved in the growth of leiomyoma and GnRHa may in part act to decrease size of leiomyoma by regulating the local levels of IGF-I, IGF-II and IGFBP-4.

Present trial was carried out to evaluate the anthelmintic efficacy of oxantel/pyrantel tablets against intestinal nematode infections, and to determine the efficacy of oxantel tablels against Trichuris infection. A total of 34 subjects with the mixed infections were treated with oxantel/pyrantel tablets (100 mg/tablet each) in a single dose of 15 mg/kg body weight, and another group of 22 Trichuris infected cases received oxantel pamoate tablets (125 mg/tablet) in a single dose of 15 mg/kg. All stool examinations were done before the treatment and 3 weeks after the treatment. The cellophane thick smear (Kato's technique) and Stoll's dilution egg counting method were employed. The results of the trial were summarized as follows: The cure rates (egg negative conversion rates) and egg reduction rates for oxantel/pyrantel tablets were 85.3 percent and 97 percent in trichuriasis, 100 percent each in ascariasis and ancylostomiasis. The oxantel tablet treated group demonstrated a cure rate of 90.9 percent and an egg reduction rate of 96.3 percent in the treatment of Trichuris. There were no detectable objective and subjective side effects in this trial. Both oxantel/pyrantel and oxantel pamoate tablets were readily accepted and well tolerated.

Painful stiff shoulder after trauma may be one of the difficult situation. Incomplete brachial plexus palsy may cause painful stiff shoulder. Symptoms and signs of this entity are vague. It is not rare to miss detecting subtle damage of the brachial plexus. We analysed these cases to identify specific clues on history and physical examination that help making the diagnosis of this entity. We have experienced 14 cases of incomplete brachial plexus palsy that showed painful stiff shoulder in Asan Medical Center from March 1995 to February 1996. All the charts and letters from primary care hospitals were reviewed. Initial diagnosis of the primary hospital, duration of delay of diagnosis after initial trauma, clues for the diagnosis in history and physical findings, patterns of the nerve injuries were analyzed. Average age was 48 years (from 25 to 84). Nine cases were male, and five cases were female. The most common primary diagnosis was proximal humerus fracture. Delayed diagnosis was the most remarkable feature. Average duration of delayed diagnosis was about three months (from one to thirteen months). Tentative diagnosis was made on the base of history and physical examination. The most frequent clue on the history was long standing painful stiff shoulder inappropriate to the initial diagnosis. The most common physical finding was tenderness at the brachial plexus area. Definite diagnosis was confirmed with electromyography. Careful history taking and thorough physical examination are essential for every shoulder injury. Incomplete brachial plexus palsy is one of the cause of painful stiff shoulder. It is important to keep in mind this entity to arrive correct diagnosis. Eletromyography should be done for the suspected cases.

The authors reviewed the clinical findings and treatment results of 12 cases of spinal meningeal cysts which were detected in MRI of low back patients. In these lesions, large cysts without CSF communication can compressed the nerve roots within spinal canal and it is difficult to confirm the cause of symptom whether it is originated from cysts or from associated spinal disorders. The terms and classifications of spinal meningeal cysts were very confusing. Among 12 cases, we excised 3 cases of large cysts with gluteal and perianal pains that were caused by compressed sacral nerve roots. All three cases were type 2 cyst (classified by Nabors) and located in sacral canal. In one case associated with isthmic spondylolisthesis, posterolateral fusion and pedicle screw fixations were combined with cyst excision. In other two cases, there were not any spinal pathologic findings that compressed sacral nerve roots except mild degenerative changes and intervertebral disc herniation in lower lumbar and sacral levels All 3 excised cases showed good prognosis in more than one year follow up. The other cases were treated conservatively for the associated spinal disorders.

Lymphomatous involvement of the gallbladder is rarely identified and manifests mostly as a local involvement of disseminated disease. There have been reported only about 20 primary malignant lymphomas of the gallbladder without involvement of other sites. A 63-year-old woman presented with jaundice, epigastric pain, and weight olss of two months duration. There was no systemic lymphadenopathy elsewhere. Abdominal computed tomograph revealed a focal thickening of the gallbladder wall. The removed gallbladder contained a well circumscribed, 5x3 cm-sized, slightly elevated firm area with accentuated mucosal papillary excrescences near the neck protion. The lesion involved whole thickness of the wall, and was made up of diffuse atypical lymphoid cell infiltrates of variable size accompanying plasmacytoid differentiation in areas. Some large tumor cells were pleomorphic and contained prominent nucleoli. To our knowledge, this is the first case of primary malignant lymphoma of the gallbladder in Korean literature.

The purpose of this study was to investigate any relationship between the geometric factors of synaptic contacts of muscle spindle afferent terminals and masseteric motor neurons in the trigeminal motor nucleus. Terminals from the masseteric muscle spindle afferents were stained with intra-axonal injection of HRP and were examined electronmi-croscopically with serial sections at the central and peripheral regions of trigeminal motor nucleus of the cat. The number of terminals examined were 76 in peripheral and 105 in central region. The results obtained were as follows. 1. Most of the labeled terminals showed simple synaptic connectivity. Each terminals in peripheral and central region made synaptic contact with 1 to 5 neuronal profiles. Two or three labeled terminals were occasionally seen to make synaptic contact with the same dendrite. 2. The average number of postsynaptic proximal dendrite per labeled terminal was higher in the central region than in the peripheral region. In contrast, that of postsynaptic distal dendrite per labeled terminal was higher in the peripheral region than in the central region. 3. The average diameter of postsynaptic dendrites in the central region was larger than that in the peripheral region. This imply terminals in the peripheral region contacted with further distal part of the distal dendrite than that in the central region. These results indicate that synaptic connectivity associated with the spindle afferents from masseteric muscle is different according to their geometric location within the trigeminal motor nucleus and suggest that there will be precise interrelationship between the morphology, pattern of synaptic connectivity and functions of muscle spindle afferents.
