1.Antibodies to Heat Shock Protein 70kDa and 90kDa in the Patients with Schizophrenia, and Their Relationship with Clinical Variables.
Journal of the Korean Society of Biological Psychiatry 1999;6(2):202-208
Schizophrenia has many clinical expression and probably different etiologic factors. Infections, autoimmune mechanism and related neurodevelopmental abnormalities have been suggested as possible etiologic factors of schizophrenia. It has been reported that immunoreactivity to heat shock proteins, which play a protective role against environmental stresses in a cell, might be related to the pathogenesis of schizophrenia. Therefore we examined the immunoreactivity to heat shock protein 70kDa and 90kDa(HSP70 and 90) in 91 patients with schizophrenia and 83 normal controls. Ig G antibodies to HSP70 and 90 of sera were quantitated by ELISA. The optical density(OD) was measured by an automated microplate reader at a wavelength of 490nm. The amounts of antibodies to HSPs were expressed as arbitrary units(AU)/ml related to a standard serum. The limit for elevated antibody titers(anti-HSPs positive or negative) was set at two standard deviations added to the mean of the normal controls. Twenty nine(31.9%) of the 91 patients showed anti-HSP70 positive and 19(20.9%) of those showed anti-HSP90 positive. On the other hand, only 1(1.4%) of the normal controls and 4(4.8%) of those showed anti-HSP70 positive and anti-HSP90 positive, respectively. The titers of anti-HSP-70 positive were related with BPRS scores, while those of anti-HSP90 positive were not. There were no relationship between antibody titers and clinical variables including age at onset, duration of illness, family history of schizophrenia or number of admission. The titers of anti-HSP70 positive were significantly associated with anti-HSP90 positive. Our results suggest the presence of abnormal immune reactivity involving HSP70 and HSP90 in a subset of patients with schizophrenia.

2.The Role of Serotonin in pathology and Treatment of the Mood Disorders.
Journal of the Korean Society of Biological Psychiatry 1997;4(2):168-178
The serotonin has been known to play important roles in pathology of the mood disorders. We summerize the evidences of serotonin in pathology of the mood disorders in a view of neuroanatomical and neurochemical aspects. Nowaday, the selective serotonin reuptake inhibitors(SSRIs)may be practically the first line of antidepressants with traditional tricyclic antidepressants(TCAs. Authors review the role of serotonin in the treatment of the mood disorders, in a view of the general considerations in selecting antidepressants, pharmacology, therapeutic, indications, side effects, doses of medication, drug-discontinuation syndrome, drug-to-drug interactions, and special therapeutic situations.

6.Computed tomography of pituitary apoplexy: report of 2 cases
Journal of the Korean Radiological Society 1982;18(1):45-48
Pituitary apoplexy, the sudden infarction, necrosis or hemorrhage into a pituitary adenoma may be threatening life and is difficult to diagnose. With an advent of CT, early diagnosis of hemorrhage into the pituitary adenomais possible if one has familiarity with its characteristic CT changes. Two cases of pituitary apoplexy are reported with brief review of the literatures. One case had a history of radiation therapy for pituitary adenoma 7 years ago, and the other had no symptoms or sings of pituitary tumor prior to onset of disease.

A putative polypeptide hormone identified as amylin[islet amyloid polypeptide] is synthesized and co-localized with insulin in B cells of pancreatic islets in several animal species including man. However, there is growing evidence that somatostatin cells are also expressed and contained amylin in the pancreatic islets of the rat The aim of the present study was to investigate the immunocytochemical expression of the amylin within the endocrine pancreas of the man, rabbit and guinea pig, with special reference to the possible ability of islet cells other than insulin cells to synthesize amylin. For this purpose serial sections of the pancreatic islets were stainedimmunocytochemically using anti-amylin, anti-insulin, anti-glucagon, anti-somatostatin antisera. In serial sections of pancreatic islets of the man and rabbit, it was shown that amylin immunoreactivity occurred in insulin-reactive B cells predominantly located in interior of the islets. In contrast, amylin immunoreacivity appeared in glucagon-reactive A cells peripherally located in the islets of the guinea pig. These results suggest that in both the man and rabbit, amylin is synthesized by B cells for subsequent co-secretion with insulin, and that in guinea pig, amylin is synthesized by A cells for co-secretion with glucagon. It thus appears that amylin release may be mediated by different secretory mechanisms according to animal species.

PURPOSE: To assess how accurately computed tomography (CY) can demonstrate the abnormal findings which are believed to cause the clinical signs and symptoms of hearing loss (HL), vertigo and facial paralysis (FP) in patients with temporal bone trauma. MATERIALS AND METHODS: The authors studied CT scans of 39 ears in 35 patients with temporal bone trauma. CT scans were performed with 1-115 mm slice thickness and table incrementation. Both axial and coronal scans were obtained in 32 patients and in three patients only axial scans were obtained. We analyzed CT with special reference to the structural abnormalities of the external auditory canal, middle ear cavity, bony labyrinth, and facial nerve canal, and correlated these findings with the actual clinical signs and symptoms. As to hearing loss, we evaluated 32 ears in which pure tone audiometry or brainstem evoked response audiometry had been performed. RESULTS: With respect to the specific types of HL, CT accurately showed the abnormalities in 84% (16/19) in conductive HL, 100% (2/2) in sensorineural HL, and 25% (2/8) for mixed HL. When we categorized HL simply as conductive and sensorineural, assuming that mixed be the result of combined conductive and sensorineural HL, CT demonstrated the abnormalities in 89% (24/27) for conductive HL and 50% (5/10) for sensorineural HL. Concerning vertigo and FP, CT demonstrated abonormalities in 67%(4/6), and 29% (4/14), respectively. CONCLUSION: Except for conductive HL, CT seems to have a variable degree of limitation for the demonstration of the structural abnormalities resulting sensorineural HL, vertigo or facial paralysis. It is imperative to correlate the CT findings with the signs and symptoms in those clinical settings.

The acardius occurs with an incidence of one in 35,000 births and is presumed to result hom vascular anastomosis between the arterial circulation of the hemodynamically larger ""pump"" twin and that of the recipient ""perfused"" twin. The perfused twin displays severe anomalies, typically referred to as acardia, that are incompatible with life. The pump twin, because of its expanded cardiac demand, may also deveolp cardiac failure, with a mortality risk of 50-70%. We experienced one case of acardiac-acephalus twin gestation diagnosed by antenatal ultrasonography, and presented this.

Placenta previa percreta is an uncommon and lifetbreatening complication of pregnancy. tbe incidence of both placenta previa and placenta acaeta are increased in patients with scaned uteri, and patienth with uterine scars and placenta previa are at inaeased risk for also baving placenta accreta. A case of placents previa percreta involving the urinary bladder was experienced and treated with surgical management. We reported a case with concerned literatures
