The development of aorticpulmonary bodies was studied by electron microscope in human fatuses ranging from 40mm to 260mm crowm-rump length. The aorticpulmonary bodies were observed in the wall of the aorta, and of the pulmonart trunk and arteries. At 40mm fetus, the aorticopulmonary bodies were composed of clusters of primitive glomus cells, primative supporting cells, unmyelinated nerve fibers, and capillaries. The primitive glomus cells possessed large nuclei, dense-cored vesicles, many Golgi complexes, rough endoplasmic reticulum, and, multivesicular bodies, the primitive supporting cells were agranular with attenuated cytoplasmic processed which partially ensheathed the primitive glomus cells. Synaptic contacts between the axon terminals and the aoma of primitive glomus cells were first observed. The primitive glomus cells increased somewhat in size and number by 90mm fetus, but retained essentially the same characteristics as at the earlier stage. Desmosome-like contacts between glomus cells and adjacent cells were commonly seen. At 160mm fetus, the glomus cells had increased accumulations of all organells and numerous dense cored vesicles. The supporting cells completely invested the glomus cells. Two types of nerve terminals were observed. One type contained small agranular vesicles which was identified as cholinergic axon terminal. The other contained a majority of small granular vesicles which was classfied as adrenergic axon terminal. Synaptic contacts between the cholinergic axon terminals and the soma of the glomus cell were observed. During next prenatal stage up to 260mm fetus the glomus cells and the supporting cells resembling those in adult were present. It is concluded that the ultrastructural features of these aorticopulmonary bodies are similar to those of the carotid body. It is therefore suggested that the aorticopulmonary bodies of the human fetures have a chemorecepter function similar to that of the carotid body.

BACKGROUND: Herpes zoster with generalized varicelliform eruptions occurs in 2 to 10% of patients with herpes zoster. It occurs mainly in old or debilitated persons especially those who have immunologic defects such as lymphoproliferative diseases, AIDS, or recipients of immunosuppressive therapy. The reported incidence of herpes zoster with generalized varicelliform eruptions is variable. OBJECTIVE: The purpose of this study was to elucidate the incidence and clinical features of herpes zoster with generalized varicelliform eruptions. METHODS: We reviewed the clinical data of 962 patients with herpes zoster by retrospective methods. The annual incidence, age, sex, seasonal variation, predilection sites, and associated conditions of herpes zoster with generalized varicelliform eruptions were analyzed from January 1990 to December 1996 (7 years). RESULTS: 1. Among 962 patients, 8 patients with herpes zoster revealed generalixed varicelliform eruptions (0.83%). 2. The age ranged from 20 to 85 and the majority of cases occurred in the 6th decade. There were 4 females and 4 males. 3. Past histories of malignancy were observed in 2 patients. However, there were no signs of malignancy at the time of diagnosis of herpes zoster with generalized varicelliform eruptions. 4. The most common site of initial lesion was the thoracic dermatome,followed by the lumbar and the cervical ones. CONCLUSION: From our observation, it is suggested that herpes zoster with generalized varicelliform eruptions may occur in patients without underlying malignancy or immunosuppressive disorders. Sudden incidental uprising of herpes zoster with generalized varicelliform eruptions was observed in 1996.

The aim of this study was to determine whether losartan, an angiotensin II (Ang II) type 1 (AT1) receptor could influence the CA release from the isolated perfused model of the rat adrenal medulla. Losartan (5~50 micrometer) perfused into an adrenal vein for 90 min produced dose- and time-dependent inhibition of the CA secretory responses evoked by ACh (5.32 mM), high K+ (56 mM, a direct membrane depolarizer), DMPP (100 micrometer) and McN-A-343 (100 micrometer). Losartan failed to affect basal CA output. Furthermore, in adrenal glands loaded with losartan (15 micrometer) for 90 min, the CA secretory responses evoked by Bay-K-8644 (10 micrometer, an activator of L-type Ca2+ channels), cyclopiazonic acid (10 micrometer, an inhibitor of cytoplasmic Ca2+-ATPase), veratridine (100 micrometer, an activator of Na+ channels), and Ang II (100 nM) were markedly inhibited. However, at high concentrations (150~300 micrometer), losartan rather enhanced the CA secretion evoked by ACh. Collectively, these experimental results suggest that losartan at low concentrations inhibits the CA secretion evoked by cholinergic stimulation (both nicotininc and muscarinic receptors) as well as by membrane depolarization from the rat adrenal medulla, but at high concentration it rather inhibits ACh-evoked CA secretion. It seems that losartan has a dual action, acting as both agonist and antagonist to nicotinic receptors of the rat adrenal medulla, which might be dependent on the concentration. It is also thought that this inhibitory effect of losartan may be mediated by blocking the influx of both Na+ and Ca2+ into the rat adrenomedullary chromaffin cells as well as by inhibiting the Ca2+ release from the cytoplasmic calcium store, which is thought to be relevant to the AT1 receptor blockade, in addition to its enhancement of the CA release.

The Loewenstein Occupational Therapy Cognitive Assessment(LOTCA) battery provides an initial profile of the cognitive abilities of the brain-injured patient that can be used as a starting point for occupational therapy intervention and as a screening test for further assessment. Reliability and validity for the LOTCA have been reported in the literatures. This study investigated the relationship between LOTCA scores and functional assessments in 34 brain-injured patients, consisting of 21 stroke patients and 13 traumatic brain injury patients. Subjects were administered the LOTCA and, as functional assessment tools, the Cognitive Capacity Screening Examination(CCSE) and the Modified Barthel Index(MBI) upon referral to occupational therapy initially, and again at discharge. The initial and the last LOTCA scores were significantly related to the initial and the last CCSE scores and the MBI scores, respectively, in brain-injured patients. Each of the last LOTCA scores, CCSE scores, and MBI scores increased significantly compared to the initial scores. There were no significant differences in the initial and the last LOTCA scores, CCSE scores, and MBI scores between stroke patients and traumatic brain injury patients. Greater LOTCA gain was significantly related to greater MBI gain. These results suggest that the LOTCA battery for brain-injured patients is related not only to cognitive function, but also to functional evaluation as activities of daily living and functional recovery at discharge.

The relationship between respiratory infections and exacerbations of wheezing in patients with wheezy bronchitis or asthma has been described. Most respiratory infections were viral or Mycoplasma pneumoniae. This study was performed to evaluate the effect of Mycoplasma pneumoniae infection on bronchial reactivity and atopic background. 106 patients with Mycoplasma pneumoniae pneumonia who were admitted to the department of pediatrics, Fatima Hospital, Taegu during the period of two years from January 1989 to December 1990 were involved in this study. The results were as follows 1) Out of 106 cases, 69 were male,37 were female and 34.9% of the cases were between 5~6 years of age. 35 cases(33.0%) had wheezing and the incidence of wheezing were higher in male than in female. 2) The incidence of wheezing was high in the patients with serum IgE level higher than 200IU/ml, patients with past and family history of allergy and the patients fed with formula feeding in infancy. 3) Eosinophils and the associated maxillary sinusitis had no effect on the incidence of wheezing. 4) The recurrence of wheezing was higher in Mycoplasma pneumoniae pneumonia with wheezing(26.8%) than in patients without wheezing(3.8%).

We examined the anatomical position of the mental foramina in mandibles foramen normal adult Koreans. 1. The percentages obtained from the study of the relationships between the mental foramen and the lower teeth showed that the most common location was type lv in which the mental foramen lay at the apex of the second promolar. The foramen between thr apices of ice two premolars (type lll) and the foramen between the second premolar and the first molar (type v) occured often and less often rspectively and find no foramen mesial to the first premolar or at the apex of the first premolar and posterior of the first molar (type l, ll, vl). 2. The study of relationship of the mental foramen to the bo of the mandible revealed that mental foramen was situated closer to the lowed border of the mandibular body. The distance ratio between the mental foramen and the alveolar crest to that between the mental foramen and the lower border was approximately 1.2 : 1. The height of the mandibular body was 31.09±2.80mm on the left side and 30.97±2.48mm on the right. 3. The distance from the mandibular symphysis to the anterior border of the mental foramen measured 29.52±2.01mm on the left, 30.82±2.04mm on the right side, and from the mandibular symphysis to the posterior border of the mandibular ramus was 104.20±4.74mm on the left, 105.44±4.49mm on the right side. It indicates that the mental foramen lies approximately at one-fourth of the distance from the mandibular symphysis to 2017-04-19 the posterior border of the ramus. 4. The distance from the superior border of the mental foramen to the bottom of the lower second premolar socket was found to be positive. It was 5.46±3.09mm on the left, 5.73±3.03mm on the right side. This indicates that the bottom of the lower second premolar socket is slightly higher than the superior border of the mental foramen.
