This study was for investigating relations between distributions of monoamines-norepinephrine, serotonin, and dopamine-on the visual system and their functions. Distributions of these monoamines in the lateral geniculate body, pulvinar, lateral posterior nucleus, and suprachiasmatic nucleus were investigated. Brain of a squirrel monkey was removed and frozen sectioned. Immunocytochemical study was performed for the tissue of the brain. Results showed that the anterior part of the lateral geniculate body contained more monoamines than the posterior part. More serotonins were distrbuted at the magnocellular part, and more dopamines were found at the parvocellular part. In pulvinar, more norepinephrines were distributed at the medial part, while serotonins were evenly distributed at all parts. In lateral posterior nucleus and suprachiasmatic nucleus, three kinds of monoamines were distributed with high density. Among the three, density of the serotonin showed the highest value. The lateral geniculate body relates with visual perception such as visual acuity, form and color perception, and stereopsis, while the pulvinar relates with visual functions, such as visual attention, sensory integration, and differentiation. Since norepinephrine and serotonine are distributed with high density in the pulvinar than in the lateral geniculate body those two monoamines are expected to playa major role for visual functions. Inferior part of the pulvinar relates with visual imagination, and the lateral posterior nucleus relates with integration of visual sensory. Relatively high distribution of dopamine in these two parts means that dopamine may playa major role for visual imagination and integration. As suprachiasmatic nucleus relates with controlling biorhythm, dense distribution of monoamines in suprachiasmatic nucleus implies that the monoamines may work for controlling biorhythm.

Herpes zoster ophthalmicus is an infectious disease caused by varicella-zoster virus. It has no predilection for sex, race, or age, though the incidence and severity of zoster is greater in the elderly. The usual site of herpes zoster ophthalmicus is the skin and eye innervated by the gasserian ganglion that receives fibers from the ophthalmic division of the trigeminal nerve. A most serious lesion is corneal ulceration, frequently complicated by other evidence of keratitis, by uveitis, and by secondary glaucoma. The treatment of zoster is difficult and frustrating for no specific therapy is known.

Pseudohypoaldosteronism (PHA) is rare herediary salt wasting syndrome due to peripheral resistance to aldostrone. PHA type I, subdivided into isolated renal insensitivity to aldosterone of autosomal dominant inheritance and multiple target organ defect of autosomal recessive inheritance, and PHA type II show similar clinical manifestations except hypertension which is limited to type II. PHA type I is charaterized by hyponatremia, hyperkalemia, high plasma aldosterone and renin activity. Variable degrees, completely asymptomatic to severe fatal, of salt loosing manifestationsdehydration, hypotension, failure to thrive, and renal tubular acidosis usually start during infancy. Sodium loss not only from kidney but also from sweat gland, salivary gland and colon may occur in some cases. Recently we experienced two cases of PHA, a 27 days of age male newborn infant with charateristic clinical symptoms and typical laboratory manifestations of PHA, confirm diagnosed as PHA type I of isolated renal defect by pilocarpin iontophoresis showing normal sodium concentration in sweat gland, and his asymptomatic 6 year-old brother with the history of salt loosing symptoms treated until second year of life diagnosed as PHA type I by markedly elevated plasma aldosterone and renin activity. Brief review and related literatures were also presented.

Decreased number of the Neuropeptide-Y[NPY] immunoreactive neurons in the corpus striatum and primary motor cortex of aged rat was detected by the immunohistochemical method. The animals were categorized into control and aged group and we used 10 Sprague-Dawley rat weighing 250-300gm for control group. 10 Sprague-Dawley rat weighing over 600gm for aged group. The number of NPY-immunoreactive neurons in corpus striatum and primary motor cortex were counted under the light microscope and the following results were obtained. 1. The NPY-immunoreactive neurons were evenly distributed in corpus striatum and in the primaty motor cortex, the NPY-immunoreactive neurons were concentrated within the layer II, III and layer V, VI. The typical NPY-immunoreactive perikarya was multipolar shape. 2. Decreased number of NPY-immunoreactive neurons were detected in some areas of corpus striatum and primary mortor cortex of the aged rat. 3. Decrease of NPY-immunoreactive neurons were most prominent in the caudate-putamen and there were moderate decrease of NPY-immunoreactive neurons in the primary motor cortex, mild decrease of NPY-immunoreactive neurons in the nucleus accumbens but the NPY-immunoreactive neurons were not observed in the globus pallidus in both control and aged rat. NPY is supposed to act as a neurotransmitter of local circuit neurons in the striatum and may exert its potent vasoconstrictor effects on cerebral vessels which influences on the microcirculation of cerebral cortex and striatum. So our results seems to provide an important data on change of the function in the striatum and primary motor cortex of aged rat brain.

To examine the clinical characteristics of ocular emergency in Sungnam, we analyzed 3784 of the eye patients who visited emergency medical center of Inha university hospital during 3 years from January 1, 1995 to December 31, 1997 The ambulation rate of eye patients was 3.97% of total patients visiting emergency medical center and the admission rate was 8.30%. Male was more common than female about 2-fold and the patients in the age of 3rd decade(30.8%) and 4th decade(23.7%) were common Regarding the eye in trouble, there was no significant difference between right eye and left eye. September and autumn were most common month and season and visit rate of Sunday(27.7%) was highest in a week. According to the arrival time at emergency medical center, largest group was between 9 PM and 12 AM and within 1 hour from the onset of disease most patients visit emergency medical center. Most frequent cause of visit was beating by fist and common ocular diseases were conjunctivitis(20.4%), orbital contusion(17.9%) and eyelid laceration(13.9%).

PURPOSE: This study aimed to evaluate the effectiveness of continuous nutritional education and oral mucositis management on the nutritive status of patients who received hematopoietic stem cell transplantation (HSCT). METHODS: After randomly allotting 72 patients who received HSCT to either an experimental group or a control group, intensive and continuous care for preventing malnutrition was conducted in the experimental group while usual routine care was conducted in the control group. The changes of the body scale, blood chemistry profile, oral intake calories, nausea and vomitus, and oral stomatitis scores were measured at three points during their hospitalization using a oral assessment guide and nutrition analysis program: admission, HSCT, and discharge day. The differences between the scores of two groups were analyzed by repeated measures analysis of covariance. RESULTS: The number of total lymphocytes was significantly improved in the experimental group after transplantation (p<.001). Nausea and vomiting score was significantly decreased in the experimental group during the conditioning regimen (p<.001). CONCLUSION: It was found that continuous nutritional education and oral mucositis control is an effective intervention by improving immune condition. Further investigations concerning direct examination of oral intake with controlling the effect of the chemotherapy are needed to ultimately discern the impact of varying oral nutrition patterns during HSCT.

Dermoid is a kind of choristoma and rare congenital benign tumor. It is ugly in appearance and especially dermoid appears at corneal limbus. The above 2 cases which we report invade cornea and it is especially giant compared with the report which has been reported untill now.
