Cystic parathyroid adenoma is one of the rare causes of hyperparathyroidism, and is usually located in neck and mediastinum. This type of adenoma tends to cause increased serum level of parathyroid hormone and alkaline phosphatase, similar serum calcium level when compared to those of solid adenoma. Thanks to current radioimmunoassay and easy accessibility to serum autoanalyzer, serum calcium level and parathyroid hormone level are more easily measured, which in turn lead to more easier diagnosis of hyperparathyroidism. Also improvement in imaging and nuclear diagnostic method of parathyroid lesion are suggested to enable easy diagnosis of cystic parathyroid adenoma. A 35-year-old male presented with easy fatigability for 12 months. The serum calcium, phosphate, alkaline phosphotase were 11.5mg/dL, 1.4mg/dL, 194IU/L respectively and his parathyroid hormone level in serum was 126.42pg/mL. Neck CT showed enlargement of right lobe of thyroid gland with well defined inhomogenously enhanced density inside the right thyroid gland. The patient was diagnosed of hyperparathyroidim due to parathyroid adenoma and was surgically removed. The surgical biopsy showed cystic parathyroid adenoma. After operation his general condition was improved and serum calcium, phosphate, parathyroid hormone level were normalizd. We report a case of hyperparathyroidism caused by cystic parathyroid adenoma with brief review of literature.

OBJECTIVES: The purpose of this study was to examine the factors related to children's health behavior. METHODS: A self-administered questionnaire survey was carried out for 431 (boys; 227, girls; 204) children, 6th grade students, in Taegu from December 14 to 18 in 1998. This study employed health promotion model as a hypothetical model. Collected data were analysed through the chi-square test, ANOVA, and path analysis. RESULTS: By univariate analysis, in case of boys, health practice was related to perceived self efficacy, perceived health status, perceived benefits of health-promoting behaviors, and perceived barriers, and in girls, health practice was related to perceived self efficacy, perceived benefits of health-promoting behaviors, perceived barriers, and cues to action. By path analysis, in case of boys, the better economic status, the younger mothers' age, the higher score of family cohesion and adaptability, healthier, the more perceived benefits, and the less perceived barriers were, the more health behaviors were practiced. Girls did the more health practice, in case of living with parents only, the higher score of family cohesion and adaptability, the more perceived self-efficacy, the less perceived barriers, and the more cues to action. Family cohesion had the most important effect on health practice of primary school students. CONCLUSIONS: In order to promote health behavior of primary school students, a good family environment as well as health education might be very important. That is, we have to try together in home and as well as in school.

GABA is an inhibitory neurotransmitter in central nervous system and produce sedative, antianxiety and muscle relaxing effects via GABA(A) receptor or GABA(B) receptor. Recently it is known that GABA is widely distributed throughout peripheral organs and may play a physiological role in certain organ. The vas deferens is innervated by species-difference. These study, therefore, was performed to investigate the mode and the mechanism of action of GABA on the norepinephrine-, ATP- and electric stimulation-induced contraction of vas deferens of rat. Sprague-Dawley rats were sacrificed by cervical dislocation. The smooth muscle strips were isolated from the prostatic portion and were mounted in the isolated muscle bath. PSS in the bath was aerated with 95/5%-O₂/CO₂ at 33℃. Muscle tensions were measured by isometric tension transducer and were recorded by biological recording system. 1. GABA, muscimol, a GABA(A) agonist, and baclofen, a GABA(B) agonist inhibited the electric field stimulation (EFS, 0.2Hz, 1mSec, 80V, monophasic square wave)-induced contraction with a rank order of potency of GABA greater than baclofen greater than muscimol. 2. The inhibitory effect of GABA was antagonized by delta aminovaleric acid (DAVA), a GABA(B) antagonist, but not by bicuculline, a GABA(A) intagonist. 3. The inhibitory effect of baclofen was antagonized by DAVA, but the effect of muscimol was not antagonized by bicuculline. 4. Exogenous norepinephrine (NE) and ATP contracted muscle strip concentration dependently, but the effect of acetylcholine was negligible and GABA did not affect the NE-and ATP-induced contractions. 5. GABA, baclofen and muscimol did not affect basal tone, and GABA did not affect the NE-and ATP-induced contractions. 6. EFS-induced contraction was inclucling 2 distinctable components. The first phasic component was inhibited by beta gamma-methylene ATP (mATP), a desensitizing agent of APT receptor and the second tonic component was reduced by pretreatment of reserpine (3 mg/Kg, IP). 7. GABA inhibited the EFS-induced contraction of reserpinized strips, but not the mATP-treated strips. These results suggest that in the prostatic portion of the rat vas deferens, adrenergic and purinergic neurotransmissions are exist, and GABA inhibits the release of ATP via presynaptic GABA(B) receptor on the excitatory neurons.

Lesch-Nyhan syndrome is an inborn error of purine metabolism resulting from hypoxanthine-guanine-phosphoribosyltransferase (HGPRT) deficiency and leading to excess purine production and uric acid over-production. It is a very rare X-linked recessive disorder, characterized by movement disorder, cognitive deficits, and self-injurious behavior. However, because of the high incidence of calculi, patients may present for surgery of urinary tract, and have increased risk of difficult intubation, aspiration pneumonia, renal insufficiency or sudden death. We report the case of a 5-year-old boy with Lesch-Nyhan syndrome who underwent successive extracorporeal shockwave lithotripsy under general anesthesia.
