This study was aimed to clarify the effects of systemic kainic acid (KA) administration (10 mg/kg i.p.) on somatostatin containing neurons, and to examine the distribution of somatostain immunoreactive neurons in the cerebral cortex of the rats. Animals were sacrificed at three time points at the two, six, and ten days after the injection of KA. Thirty-six rats were observed by using the free-floating immunohistochemical method (modified ABC method). The results were as follows: 1) In the anterior and posterior cingulate cortex, somatostatin immunoreactive neurons were not observed in 2,6,10days after treatment of KA including control group except Cg 1 showing some somatostatin immunoreactive neurons in 10days and control groups. 2) In the insular cortex, somatostatin immunoreactive neurons also were not observed in any groups except AIV showing few somatostatin immunoreactive neurons in control group. 3) In the perirhinal cortex, few somatostatin immunoreactive neurons were observed in 2 days and 6 days groups. In control group, a number of somatostatin immunoreactive neurons observed. 4) A strong decrease of somatostatin immunoreactive neurons were observed in the frontal, arietal, temporal and occipital cortex 2 days after treatment of KA. Initially decreased somatostatin immunoreactive neurons had recovered to control 10 days after treatment. 5) Distribution of the somatostatin immunoreactive neurons was observed marked difference according to the cortical areas. Somatostatin immunoreactive neurons in isocortex were more increased in number than the allcotex by control study. The changes in somatostatin immunoreactive neurons after systemic treament of KA were marked in 2 days and 6 days, but these had recovered to control 10 days the treatment of KA. It suggested the normalization of the cerebral function 10 days after seizure. According to the cerebral cortex, the different distribution of somatostatin immunoreactive neurons in number was observed.

The authors analysed 196 cases of convulsive disorder in children who were admitted to the pediatric department of Kyunghee Hospital from June 1993. Blood samples were drawn immediately following seizures on arrival. Serum prolactin values were measured by radioimmunoassay. The results obtained were as follows: 1) Mean serum prolactin value was 55.4+/-20.8ng/ml in generalized seizures within 1 hr following seizures, 22.5+/-3.9ng/ml in partial seizures. There was a significant difference between generalized scizures and partial scizures (p<0.05). 2) Mean serum prolactin value was 23.5+/-9.7ng/ml in generalized seizures within 1~3 hrs following seizures, 10.4+/-4.9ng/ml in partial seizures. There was a significant difference between generalized seizures and partial seizures (p<0.05). 3) Mean serum prolactin value was 9.5+/-4.4ng/ml in generalized seizures 3 hrs following seizures, 9.8+/-4.8ng/ml in partial seizures. There was no significant difference between generalized seizures and partial seizures (p>0.05). We found transient hyperprolactinemia following generalized seizures but a little change following gartial seizures. Postictal elevation of serum prolactin may represent a biochemical marker of generalized and partial seizures.
