BACKGROUND AND PURPOSE: Valproic acid (2-propylpentanoic acid) which enhances GABA synthesis and blocks it's degradation has been useful treatment of migraine and may activate GABA receptors to modulate trigeminal nociceptive neurons innervating the meninges. But the mechanism and action of sodium valproate in headache is not clear. To investigate the mechanism of valproic acid action in headache model, we compared the change of dural plasma protein extravasation in both substance-P neurogenic inflammation rats with valproic acid pretreatment and without valproic acid pretreatment. METHOD: Sprague-Dawely rats were pretreated with valproate 30 minutes prior to substance-P administration in order to test the effects of sodium valproate on dural plasma protein extravasation by detecting the amount of extravasated Evans blue in the dura matter. To examine the abilities of either bicuculine (GABAA antagonist) and phaclofen (GABAB antagonist) to reverse the effect of valproate, they were administered 5 min before valproate administration. After then we also test the effect of muscimol (GABAA agonist) and bicuculine (GABAA antagonist) in substance-P induced neurogenic inflammation rats. RESULTS: Intraperitoneal injection of sodium valproate and muscimol reduced dural plasma protein extravasation after intravenous substance-P administration. The GABAA antagonist bicuculine completely reversed the effect of valproate and muscimol on plasma extravasation following substance-P administration, whereas the GABAB receptor antagonist, phaclofen, did not. CONCLUSION: We concluded that the attenuation of dural plasma protein extravasation by valproate and muscimol is mediated by via GABAA receptors within the meninges. Agonists and modulators at the GABAA receptor may become useful for the development of selective therapeutic agents for migraine headache.

Average anteversion of the femur is 15.3 degree. Ultrasound, computerized tomogram, and three dimensional reconstruction from CT or MRI have been used for more accurate measurement of the anteversion. There are two methods in measuing anteversion angle from CT scan:one is by drawing a mid line through long axis of the femoral neck (conventional method). Another is by drawing a line from the center of the head to that of the neck at the base of the trochanter using several cut slices (Murphy’s method). We compared these methods with fluoroscopic measurement of the Anteversion. We traced the change of the anteversion before and after closed femoral intramedullary (IMO) nailing to evaluate the origin of malrotation of the femur. 1. Normal anteversion angles were measured in 15 cases. Average anteversion angle was 6.9 degrees by conventional method, 12.3 degrees by Murphy’s method, and 12.2 degrees by fluoroscope. 2. Anteversion angles were measured after IM nailing in 18 cases. Average was 17 degrees by Murphy’s method and 15.2 degrees by fluoroscope. Mean of difference between these two methods sea 6.3 degrees. That was 1.7 degrees in normal side. 3. Change of the anteversion angle between before and after IM nailing was measured in 17 cases by fluoroscope. Average anteversion angle before the operation was 11.9 degrees and it was change to 15.8 degrees after operation. Mean of these change was 7.1 degrees. 4. Pereperative traction provides important information on change of anteversion. Reduction excessive flexion of proximal fragment was a origin of change of anteversion during nailing procedure. Conclusion : Malrotation of the femur after IM nailing must be keep in mind and it may be preventable by fluoroscopic control of the rotation in nailing procedure.

During the period from July 1975 to June 1982 we performed 17 Putti-Platt operations on 16 males and one female, ranging from 19 to 39 years. The average follow-up period was 3.8 years in 13 cases of them. The results were as follows: 1. The ages in initial dislocation were ranged from 14 to 31 with an average of 18.5 years. 2. Right side was involved in 15 cases and. left in 2 cases. 3. On radiological finding Hill-Sachs lesion was found in 41%.0n pathological finding at operation of 15 cases, Bankart lesion was seen in 73%, Hill-Sachs lesion in 60%, glenoid erosion in 33%, capsular loosening in 33%, and capsular tear in 13%. 4. Limitation of external rotation compared with sound opposite side was measured in 12 to 40 with an average of 19.2 degrees. 5. The Putti-Platt operation is considered as sound, surgical procedure that gives excellent functional results.

The Changes of soluble Fas levels in Patients with Autoimmune Thyroid Diseases BACKGROUD: Apoptosis was observed in thyroid tissue from Hashimoto disease but not those from Graves disease. Recently Fas and Fas ligand interactions among thyrocytes were suggested to development of clinical hypothyroidism in Hashimoto disease.Soluble Fas produced as the form lacking the tranmembrane domain due to alternative splicing, is supposed to inhibit Fas-Fas ligand interaction and blocks Fas mediated apoptosis. METHODS: In tbis study, we measured serum soluble Fas to determine the possible involvement of this molecule in the autoimmune thyroid disease by enzyme linked immunosorbant assay in 29 patients with Graves disease, 30 patients with Hashimotos disease and 19 normal controls. RESULTS: Compared with normal subjeets (4.26 +/- 1.00 U/mL), soluble Fas was not increased in patients with Graves disease (4.23 +/- 1.14 U/mL, p>0.05) but it was increased in throtoxic Graves patients (4.70 +/- 1.26 U/mL, p<0.05) compared to euthyroid Graves (3.72 +/- 0.73 U/mL, p<0.05) and normal subjects (4.26 +/- 1.00 U/mL, p<0.05). The euthyroid and hypothyroid patients with Hashimoto disease showed low soluble Fas levels, 2.94 +/- 0.54 U/mL and 2.74 U/mL, respectively compare to the patients with Graves disease and normal subjects. The thyroid hormone levels to (T3 T4 and free T4) showed positive correlation with the serum titers of antithyroid autoantibodies, antithyroglobuin antibodies, antiperoxidase antibodies and thyrotropin binding inhibitor immunoglobulins. CONCLUSION: We found that the patients with thyrotoxic Graves disease had increased level of serum soluble Fas and the patients with Hashimoto disease showed low levels of soluble Fas compared to normal controls. Increased soluble Fas in Graves disease suggests increased expression of alternatively spliced Fas mRNA variant and decreased soluble Fas in Hashimoto disease suggests decreased Fas mRNA variant and increased full length membrane Fas, so these findings are related to the promotion of apoptosis of thyroid cells during autoimmune reaction in Hashimotos disease.

Becker muscular dystrophy is a X-linked recessive disease with the affected gene at locus Xp21, characterized by progressive muscular weakness. Without the definite family history, it has been known that the diagnosis of this disease is almost impossible on clinical grounds alone. We reviewed the muscle pathology of two casses of genetically confirmed Becker muscular dystrophy to know the diagnositc significances of this study. The first case, a 20 year old man, is the classical one with definite family history of X-linked recessive heredity. The muscle pathology of the biceps showed dystrophic muscular changes, including increased internal nuclei, marked variation of fiber sizes and mild endomysial fibrosis. The dystrophin stain of the muscle was also confirmative for the diagnosis. The second case was a 32 year old man who has been biopsied his left vastus lateralis 5 years before this genetic diagnosis. This case is a sporadic one without the family history. The diagnosis at the time of muscle biopsy was limb-girdle muscular dystorphy or inclusion body myositis because of the typical rimmed vacuoles and marked variation of fiber sizes. The dystophin stain was not available at that time. Our conclusion is that the molecular genetic study and/or dystrophin protein test of muscle biopsy should be done in every clinically suspected patient, including limb-girdle muscular dystorphy, inclusion body myositis or rimmed vacuolar myopathies.

OBJECTIVE: Congenital bilateral perisylvian syndrome (CBPS) has been defined as a characteristic malformative perisylvian polymicrogyria (PMG) in patients with clinical symptoms of pseudobulbar palsy and epileptic seizures. For the present study, we investigate clinicopathologic features of CBPS associated with timing of lesion formation. METHODS: Clinicopathologic features of CBPS from 6 patients with surgical resection of the cerebral lesions due to medically intractable seizures were studied. RESULTS: Seizure onset ranged from 1 to 10years (average 6.7years) of age, and average duration of seizure was 23years. All had complex partial seizures, and two patients had additional tonic clonic seizures. Magnetic resonance (MR) images showed polymicrogyria, atropic gyri with gliosis. In the histopathologic examination, the cortical lesions revealed features of ulegyria ; atrophic and sclerotic gyri, laminar loss of neurons, extensive lobular gliosis throughout the gray and white matter, neuronoglial nodule formation, and many amyloid bodies. Unlayered or four-layered PMG was not identified. CONCLUSION: Above data suggest that CBPS might be caused by ulegyria resulting from developmental cortical defect during early fetal stage or acquired hypoxic/ischemic injury in prenatal or postnatal life.
