OBJECTIVE: Asymmetries in evoked potential P300 topography of schizophrenia and bipolar disorder are still controversial. The purpose of this study was to examine the difference in P300 topography between schizophrenia and bipolar disorder. METHOD: P300 was recorded from 16 schizophrenic, 15 bipolar manic, and 16 control subjects. All were right-handed. Subjects silently counted target stimuli(2.0kHz) among trains of standard stimuli(1.0 kHz). Averages were constructed from brain responses to target stimuli. RESULTS: 1) Schizophrenics displayed significantly smaller peak amplitude of P300 over Cz, Pz, T3 than controls. 2) Schizophrenics displayed significantly smaller peak amplitude of P300 over T3 than bipolar manics. 3) Schizophrenics displayed significantly smaller peak amplitude of P300 over T3 than their T4. 4) Schizophrenics displayed significantly delayed latency of P300 over T3 than bipolar manics. 5) Schizophrenics displayed significantly delayed latency of P300 over T3 than their T4. CONCLUSION: Left-sided P300 abnormality, especially left superior temporal gyrus, in schizophrenics, relative to bipolar manics and controls suggests that psychophysiological cause of schizophrenia and bipolar disorder is different and P300 asymmetry is specific to the psychophysiological cause of schizophrenia.

Authors report a case of separation anxiety disorder, which developed as a side effect during haloperidol treatment of Tourette syndromes(TS). In this case, 14 years old boys developed attention deficit symptoms during his infancy. At 4th grade of primary school, he developed vocal tic, motor tic, and coprolalia. With 5mg/day of haloperidol treatment his symptoms of TS were subsided. During the treatment, he developed features of separation anxiety disorder, including dependence, pleading, clinging, and sadness. Symptoms of attention deficit and separation anxiety disorder were improved by 25mg/day of imipramine treatment. During haloperidol treatment of TS, careful observation may be needed whether separation anxiety disorder-like symptom develops.

OBJECTS: Sanjoin, the seeds of Zizyphus vulgaris var. spinosus has been used as the most important hypnotic agent in chinese medicine to treat insomnia. This research was performed in order to examine the effect of betulinic acid and sanjoinine-A which are components of Sanjoin. METHOD: Sleeping time, sleep recordings of EEG, serum serotonin level, and locomotor activity were measured in rats which received betulinic acid and sanjoinine-A as sleep induction material extracted from Sanjoin. RESULTS: 1) Groups received betulinic acid, sanjoinine-A, and lorazepam showed increased sleep time than control group with saline. 2) Groups with betulinic acid, sanjoinine-A, lorazepam and saline recorded beta-wave in sleep recording of EEG. In there was no significant difference among all groups. 3) No significant difference in serum serotonin level among all groups was found. 4) In autonomic activity testing, groups of betulinic acid, sanjoinine-A, and lorazepam showed significantly more decreased in activity than saline group. In comparison of groups of betulinic acid and sanjoinine-A with a group of lorazepam, there was no significant difference. CONCLUSION: These results suggests that betulinic acid and sanjoinine-A have the sedative effect like lorazepam rather than sleep effect.

A case of toxic epidermal necrolysis (TEN) was presented in 46 year-old male patient. The characteristic skin lesions of TEN were developed after some medictions and tetanus anti-toxin (TAT) injection due to trauma. Probably, the cause of the disease was drugs, TAT injection or trauma inself. On the pathologic findings, lower epidermis and dermo-epidermal cleavage were noticed. He was treated with massive antibiotics and steroid. About 7 days after therapy, much improvement achived. However foul odorous yellowish discharge was noticed since 20 days of hospitalization. Wide debridement of necrotic tissue was carried without improvement. Patient expired on 48th hospital day due to sepsis and impending hepatic coma.

Serum zinc is an essential element in men and animals. Recently on the dermatologic fields, the serum and the skin levels and the roles of zinc have been studied especially in acne vulgaris, but the results were controversial. So to confirm the previous reports and for evaluation of the relationship between the various aspects of acne vulgaris and the serum levels of zinc, the serum levels of zinc were measured by atomic absorption spectrophotometer in 13 healthy controls and 46 patients with acne vulgaris. In the healthy controls, their mean values of zinc were 0.843+0.251 ppm in total, 0.920+0.219 ppm, in females and 0.777+0.260 ppm in males. There was no statistical difference attributable to sex. In the 46 patients with acne vulgaris, their mean value of zinc was 0.741+0.195 ppm. There was no significant difference in the mean serum zinc level compared with the controls. In the males with acne, the mean va1ue of zinc was 0.727+0.166 ppm, and 0.748+0.208 ppm in females with acne. There was no significant statistical difference between males and females with acne. And females, but not males, with acne had significantly lower serum zinc levelss than controls of the corresponding sex. (p<0.1) By clinical severity, classifying the 46 patients with acne vulgaris into three groups: mild type (only comedones), moderate type (comedones with pa.pules) and severe type (includes pustules, comedones, and papules, etc.), the serum zinc levels of each group were 0.774+0.185 ppm, 0.7880. 200 ppm and 0.666+0.176 ppm. The significant statistical difference was found only in the severe type of acne compared with the healthy controls (p<0.05). Also classifying the patients into three groups (acute, moderate and chronic types of acne) by duration of acne, the serum values of zinc were 0.738+0.158 ppm, 0.692+0.283 ppm and 0.769+0.241 ppm, respectively. Only in the moderate type of acne, the mean serum level of zinc was significantly reduced compared with the control group (p<0.1)

This study was designed to investigate the effect of GABA and related substances on the spontaneous contraction of rat small intestine. The rats (Sprague-Dawley), weighing 200-250g, were sacrificed by cervical dislocation, and the small intestine was isolated. Longitudinal muscle strips from duodenum, jejunum and ileum were suspended in Biancani's isolated muscle chambers and myographied isometrically. GABA and muscimol, a GABA A receptor agonist relaxed the duodenum and jejunum significantly, but baclofen-induced relaxation in those muscle strips negligible. The effectiveness of GABA and muscimol in various regions were the greatest on duodenum, and greater on jejunum than on ileum The effect of GABA and muscimol was antagonized by bicuculline, a competitive GABA A receptor antagonist and picrotoxin, a noncompetitive GABA A receptor antagonist. Duodenal relaxation induced by GABA and muscimol was unaffected by hexamethonium, but was prevented by tetrodotoxin. These results suggest that GABA inhibit the contractility of smooth muscle with distinct regional difference of efficacy, and the site of inhibitory action is the GABA A receptor existing at the presynaptic membrane of postganglionic excitatory nerves.

BACKGROUND: Hypersalivation can be a troublesome side effect of clozapine, limiting its usefulness in the management some cases of schizophrenia. But the pharmacodynamic basis of clozapine-induced hypersalivation remains obscure. Object : The aim of this study was to evaluate the effect of the alpha2-adrenergic agonist clonidine on clozapin-induced hypersalivation in the patients who were receiving clozapine. METHOD: Twenty one schizophrenic inpatients on clozapine participated in the study. The amount of saliva was measur on the 7th day at 8pm after starting clozapine treatment. Of them, 15 patients who had experienced hypersalivation treated with 0.1mg/day of clonidine. RESULT: Of 21 schizophrenic patients treated with clozapine in the psychiatric inpatients clinic, 15(71.4%) complain hypervalivation. After clonidine treatment, mean salivary flow-rate was decreased significantly in these patients. CONCLUSION: Clozapine-induced hypersalivation could be decreased by administration of alpha2-adrenergic agonist clonidine are compliance could be improved. Also our study supports the notion that increased adrenergic tone contributes to clozapine induce hypersalivation.

OBJECT: This study was performed in order to examine the correlation between acute neuroleptic-induced dystonic reactions and serum iron level. METHOD: Serum iron levels were measured in psychiatric inpatients who had developed acute neuroleptic-induced dystonia(N=41) and in control patients with no history of acute dystonic reactions(N=37). Serum iron levels were compared in acute dystonic inpatients before starting treatment with neuroleptics and after acute dystonic reaction. RESULTS: The patients exhibiting acute dystonic reactions had significantly lower serum iron levels than the patients without acute dystonic reactions. CONCLUSION: This result supports an association between low serum iron and the occurrence of neuroleptic-induced acute dystonic reactions.

Journal of Korean Neuropsychiatric Association 2001;40(5):885-892
BACKGROUND:To evaluate the efficacy of lamotrigine on bipolar disorder, both manic and depressed episode, the author compared the effects of lamotrigine with lithium and placebo. METHOD: Forty-seven manic patients with bipolar disorder and 43 depressed patients with bipolar disorder were treated with lamotrigine, lithium or placebo during 6 weeks. Their severity of symptoms were rated weekly using Young's Rating Scale for Mania and Hamilton Rating Scale for Depression. RESULTS: In manic patients the therapeutic efficacy of lamotrigine was lower than that of lithium during baseline to week 2, but after week 3, lamotrigine was as effective as lithium. In depressed patients the therapeutic efficacy of lamotrigine was superior to lithium from week 2 to endpoint. Most patients tolerated well except that one patient developed skin rashes. CONCLUSION: Lamotrigine seems to have antimanic and antidepressant effect as lithium in the treatment for acute bipolar disorder.
