The development of immuohistochemistry and the application of electron microscopy have revolutionized our understanding of the pathopysiology of pituitart adenoma. The clinical value of functional characterization of pituitary adenoma has been realized. Immunohistochemical stains using polyclonal antibodies to six pituitary hormones (GH, PRL, ACTH, TSH, FSH & LH) were performed to classify the pituitary adenoma and to investigate the relationship between the results of the immunohistochemical study and pared to the serum hormone level. The results are summarized as follows: The Most common clinical type of pituitary adenoma was prolactinoma and the second was nonfunctioning adenoma. However, the most common immunohistological type of pituitary adenoma was null cell adenoma, the second one, lactotrope adenoma and the third one, mixed sommatotrope & lactotrope adenoma. In the clinically nonfunctioning adenoma cases, null cell adenoma were present in 75%; gonadotrope adenoma and corticotrope adenoma were present in 25%, while the serum prolactin level was increased in ten of the twenty cases(50%) of the null cell adenoma. When the serum prolactin level was increased above the 150ng/ml, the tumor cells gave positive reactions in 95.2% of cases immunohistochemically. But in the cases of GH, FSH & LH, the tumor cells gave positive reactions in 100%, 75%, and 66.7%, respectively. In the case of increased serum prolactin level, more than 50% and 30% proportion of tumor cells showed positive reactions in the micro- and macroadenoma, respectively.

BACKGROUND: To comparatively analysis the epidemiological changes in the acute drug intoxication between 1980s and 1990s. METHODS: We reviewed retrospectively the medical records of the patients with acute drug intoxication in the emergency department of the Inha hospital from June 1986 to April 1987 and from June 1996 to May 1997. And we performed comparative analysis between two result. RESULTS: The ratio of the acute drug intoxication in the emergency medical center was reduced significantly in 1990s against 1980s. Sexual ratio and prevalent age group has no significant interval changes between 1980s and 1990s. The prevalent seasons were Spring in 1980s and Summer in 1990s but has no significance. The most commonly used drugs was rodentides in 1980s and hypnosedatives in 1990s and shown significant interval changes. The most common motive was suicidal attempts in both 1980s and 1990s, but significantly reduced. After emergency treatment the rate of curative-discharge has improved and the rate of admission has decreased significantly in 1990s against 1980s. The most critical agent was agricultural chemicals in both 1980s and 1990s. The mortality rate has no significant interval changes. CONCLUSION: There were some significant interval changes of the acute drug intoxication in prevalence rate, commonly used drugs, ratio of suicidal attempt and curative-discharge rate between 1980s and 1990s. New education programs far preventing acute drug intoxication and strict legal control of drugs are important and necessary.

Seventeen cases of Kienbock's disease were treated since 1982, and analysed their clinical outcomes to confine the pathogenesis and to make sure the best way to treat them in various stages. It was not related to trauma around wrist joint (35.3%) but significantly closed to ulnar negative variances(64.7%). Ulnar tilt angle was increased definitely upto 28.9° compared with normal value (22°) in ulnar negative variance, but volar tilt angle was within normal limits. The packing with tensor fascia lata or palmaris longus tendon after the complete excision of avascular lunate could not prevent the collapse of carpal bones at long-term follow-up. But the triscaphe fusion was most effective to maintain the normal wrist anatomy, and radial shortening than ulnar lengtherning is thought to be more effective in wrist biomechanics of kienbock's disease with ulnar negative variances.

BACKGROUND: Dizziness is a common complaint in patients presenting to the emergency room and that has various pathologic causes. This study investigate the clinical differences in dizziness between the central origin and the peripheral origin and to provides the clues far diagnosis and proper treatment. METHODS: We analysed 290 patients with dizziness during 12 months period prospectively, who visited in ED, Inha University Hospital from Jan. 1997 to Dec. 1997. We analysized sex ratio, characteristics of the dizziness, associated past illness, associated symptoms, severity, results of the special radiologic study, nystagmus type, and causes of central origin and peripheral origin dizziness. RESULTS: Male to female ratio was 1:1.4 in central origin(n=165) and 1:2.0 in peripheral origin(n=125). Most common age group was 11th decade in both groups. According to the characteristics of the dizziness, rotation sense was the main complaint of the peripheral origin dizziness. Most common past illness was hypertension in both groups. MRI has diagnostic priority than CT scan in central origin dizziness. Types of nystagmus has some significant differences between two groups. CONCLUSION: Dizziness may represented as a sign of significant pathological neurologic status especially in central origin. So we must precisely evaluate the patient history, neurologic examination of the inner ear and CNS, and special radiologic study incliding MRI.

Infertility is a world wide problem affecting up to 15% of married couples. Although it is well known that male factor is the important cause of the infertility in 40-50% of the cases, the appropriate drugs for treating this condition have not yet been established. With certain exceptions, the etiology of many cases of male infertility is unknown. For such cases, various drugs including both hormonal and non-hormonal agents are sometime prescribed, but there have been no entirely satisfactory results. The present investigation would assess the effectiveness of Korean Ginseng, herbal medicine in the treatment of male infertility during the period from September to December, 1988, at the Andrology Clinic of the Department of Urology, Seoul National University Hospital. This herbal medicine was selected because its ingredients accelerate the metabolism of lipids and synthesis of DNA, RNA and proteins. This medicine contains ingredients which build resistance against stress since many of male infertility are under stress and also is to control immunological disorders. Ginseng has steroid-like, anti-allergic and anti-inflammatory actions, and accommodates the blood-testis barrier, improve digestive functions and peripheral blood flow. Accordingly, Ginseng has been used as an agent restoring healthy conditions to maintain homeostasis or to keep physical and mental balance. Extensive chemical investigation on Ginseng has revealed that Ginseng contains characteristic dammarane-type triterpenoid saponins as the main principles. These saponins are called ginsenosides and represent the principal pharmacological actions of Ginseng. The ginsenosides react at the hypothalamus-pituitary-gonadal axis. The decreases of sexual drive and disorders of fecundity under challenge of stress are prevented by oral administration of ginsenosides. To assess the efficacy of treatment with Ginseng which is alleged to improve spermatogenesis in idiopathic infertile selected patients. Participants in this study are men with primary idiopathic oligospermia and asthenospermia. The inclusion criteria would be as follows : a) men aged 20-40 years, whose female partners are entirely normal. b) men having vaginal intercourse with one partner and without psycho-sexual problems. c) men willing to enter this clinical trial and relying only on the drug administered throughout the study. d) no history of serious chronic physical or psychological diseases. e) men whose female partners are not using any method of birth control. f) men with no history of drugs to treat sperm disorders within 3 months. A total of 12 patients with sperm counts of less than 20 x 10 6/ml (oligospermia group), and 5 patients with sperm motility of less than 20% (asthenospermia group) are selected as the study subjects. Parameters to be assessed are as follows : Before and after Ginseng administration, history taking, physical examination with testis size measurement, laboratory works including urinalysis, CBC, seminal fructose, semen analyses (pH, volume, density, motility, activity grade, morphology, fertility unit, and WBC), plasma hormonal assays (FSH, LH, testosterone, estradiol, and prolactin). Before starting the treatment, 2 semen samples are obtained preteded by 3 days of abstinence. For follow-up, patients will have a semen sample taken every month while in treatment. After the treatment, more than 2 semen analyses will be undertaken for the final evaluation. Treatment scheme is as follows : The composition of the Ginseng extract used in this clinical trial consisted of the standardized highly concentrated Ginseng extract G115, 100mg : concentrated standardized lectithin, 95mg , alpha tocopherol, 10mg ; and excipients q.s.ad. This Ginseng extract named Ginsana capsule produced by Pharmaton-Korea Co., Ltd. Four capsules of Ginsana are given twice a day by mouth before meal for more than 90 days to be justified on the basis of general assumption that spermatogenesis cycle lasts approximately 74 days. The results of the clinical investigation are considered to be effective, if more than double of improvemant being noted on the count or more than 30% ot improvement being noted on motility beyond the pre-treatment levles. Clinical characteristics of a total of 17 patients are listed in the table 1. The outcomes of this trial are presented as follows : (tables 2 and 3). Coital frequency increased from 2.6/week before Ginsana exposure to 3.1/week after the treatment. General health such as stamina, body weight and spirits improved in 10 patients of the 17 after Ginsang treatment. Regarding hormonal partmeters (table 2), Plasma FSH and LH were not changed much before and after Ginsana administration. Patients with low FSH and LH levels before the treatment and patients with high range of prolactin levels before the treatment have a tendency to improve more in semen parameters after the treatment. Hyperestrogenemia was decreased and plasma testosterone levels increased after Ginsana treatment. Subsequently, T/E2 ratio resulted in normal to help spermatogenesis. Regarding the semen parameters (table 3), sperm counts increased in 58% of the patients in oligosperrnia group after oligospermia group. Sperm motility improved in 33% of the patients rn oligospermia group after the treatment. Mean motility increased from 34% to 45% after the treatment in oligospermia group. Activity grade and fertility unit were also improved in oligospermia group after the treatment Other parameters such as volume, normal morphology, pH and seminal fructose were not changed significantly before and after Ginstna treatment. Only one case showed an improvement in sperm counts and motility of a total of 5 patients with asthenospermia. Pregnancy resulted in 2 patients of improved cases and 1 patient of not improved cases in oligopsermia group after Ginsana administration. So that, pregnancy rate was 25 % of the oligospermia group. The study results of some imvestigators are summarized in the table 4. From these results, Ginsana appears mainly act on testis directly, restore the steroidogenesis, resulting in the stimulation of spermatogenesis. in conclusion, the authors clinical experience confirmed that Ginsana, a traditional Chinese medicine, appears to be of value particularly in the trettment of idiopethic oligospermia without any noticeabel adverse side effects.

Optic nerve sheath meningioma arises from the arachnoid cap cell of optic nerve sheath and comprises most of primary orbital meningioma. We experienced a rare case of optic nerve sheath meningioma originating in the left orbit. A 44-year-old woman had suffered from visual disturbance in the left eye for 3 years and had only light perceptibility for the recent 6 months. The right eye was normal. Brain CT scan and MRI revealed a 2x0.8 cm sized fusiform solid mass in the left retrobulbar area. Under the impression of optic nerve tumor. excision of the mass including a small segment of the optic nerve was performed. The tumor was a yellowish firm, relatively well demarcated mass that encircled the optic nerve without infiltrating it. Microscopically it was a typical meningioma, meningothelial type. The recovery of visual acuity was impossible due to resection of optic nerve but there was no evidence of recurrence for u months.
