PURPOSE: GH-releasing peptide(GHRP-6) was shown to possess strong GH-releasing activity both in vitro and in vivo. Chemically,GHRP-6 has no primary sequence homology with GHRH. The GH releasing activity of GHRP-6 has been demonstrated in several animal species including humans. GHRPs could have a considerable physiological and clinical useful for treatment of GH deficient and/or non GH deficient short children in the near future. The aim of this study was to evaluate the GH-releasing activity of GHRP-6 in anterior pituitary cell culture and compared to that of GHRH . METHODS: Spraque-Dawley rats were decapitated and pituitary glands were collected in ice-cold PBS. The anterior pituitaries were minced into small fragments and dissociated by enzymatic digestion. These pituitary cells were suspended in Dulbecco' modified Eagle' medium(DMEM) with fetal calf serum at a concentration of 106cells/mL and then plated onto multiwelled dishes at a density of 1.5*05 cells per 6 well plate. GHRP-6 treated group(10-8, 10-7, 10-6 M), GHRH treated group(10-8, 10-7, 10-6 M) and combined GHRP-6 and GHRH treated group were classified. After replacement of each GHRP and/or GHRH+GHRP, the released GH were measured with RIA in 10 min, 20 min, and 30 min. RESULTS: 1) GHRH(10-8) treatment increased GH release by 15.8+/-3.9ng/mL in 0 min., 69.8+/-4.3ng/mL in 10 min. 78.3+/-5.0ng/mL in 20 min. and 67.8+/-7.2ng/mL in 30 min. In case of GHRP-6(10-8M) treatment increased GH release by 11.0+/-1.4 in 0 min., 90.3+/-12.2 in 10 min., 78.3+/-4.5ng/mL in 20 min. and 78.0+/-4.8ng/mL in 30 min. The released GH levels were markedly increased in 10 min. after GHRP-6 and were not singificantly different from that of GHRH. 2)GHRP+GHRH(10-7M+10-8M) treatment increase GH release by 8.8+/-1.5ng/mL in 0 min., 37.8+/-9.3ng/mL in 10 min., 41.3+/-8.1ng/mL in 20 min. and 40.0+/-7.9ng/mL in 30 min. The released GH levels after GHRP+GHRH treatment was not markedly increased statistically compared to GHRH only. CONCLUSION: GHRP-6 could release GH in rat anterior pituitary cell culture and the released GH amounts were not significantly different from that of GHRH. There was no synergistic additive effect in GHRP+GHRH in rat pituitary cell culture.

Prostate specific antigen (PSA) is known as the most sensitive marker for detecting prostate carcinoma (CaP). Nevertheless, PSA testing lacks sufficient sensitivity and specificity to be considered the perfect tumor marker for the detection of early prostate cancer. PSA exists in the serum in several molecular forms; free PSA and complexed PSA (PSA complexed to alpha-1-antichymotrypsin or a-2-macrogloburin or inter-alpha -trypsin inhibitor). It has been suggested that analysis of level of free to total PSA ratio improves specificily of PSA assays in the early detection of prostate carcinoma. We measured free PSA and total PSA of 367 healthy men aged from 30 to 79 years old using radioimmunoassay (PSA-RIACT and FPSA-RIACT kit) in order to know the normal range of PSA, free PSA and free PSA to total PSA ratio. The mean free to total PSA ratio in normal Korean men is 0.31+/-0.14 and there is no correlation with patient age.

Leiomyosarcoma of the prostate is a rare malignant tumor. It originates from the smooth muscles of the prostatic gland and is usually found during old ages. Prognosis is usually poor especially in childhood. We report a case of leiomyosarcoma of the prostate measured 320gm in 64 years old man.

A number of noninvasive technics have been advocated as reflecting left ventricular performance. These methods include systolic time intervals, echocardiography and imaging of the left ventricular chamber with radionuclides during systole and diastole. Radionuclide evaluation of left ventricular function by means of the gamma camera and gating currently appears to be the most reliable noninvasive method for approximating angiographic evaluation of left ventricular performance. Utilizing the radionuclide angiography, we measured the left ventricular function in 19 normal healthy control, 60 patients with coronary artery diseases 7 patients with dilated cardiomyopathy, 5 patients with hypertension. 1) Left ventricular ejection fraction decreased in 12 patients with anterior myocardial infarction (39.9+/-11.6%), 17 patients with inferior myocardial infarction (49.9+/-8.4%) and 7 patients with dilated cardiomyopathy (19.0+/-5.8%), and there was a statistically significant difference compared with 19 normal control group (63.5+/-8.2%)(p<0.005). However there were no statistically significant difference between normal control group, patients with hypertension (58.8+/-7.6%) and patients with angina pectoris (60.1+/-6.5%). 2) Left ventricular ejection fraction decreased in both anterior and inferior myocardial infarction, and there was a statisically significant difference between both groups (p<0.01). All 13 patients with acute myocardial infarction had abnormal LVEF (40.5+/-9.1%) whcih was significantly lower than that of 16 patients with old myolardial infarction (50.1+/-10.5%)(p<0.01).

The pathophysiology of pediatric encopresis has been incomprehensible. The current study was designed to assess its clinical and physiologic findings. Moreover, outcome of treatment was evaluated. METHODS: The clinical and functional findings of 18 patients (13 boys, 5 girls) were analyzed, retrospectively. Physiologic studies for cooperative child included anal manometry (n=12), cinedefecography (n=3), and PNTML (pudendal nerve terminal motor latency, n=1). For exclusion of the organic cause, barium contrast study was carried out in all case. Patients were categorized by leading symptom as constipation or incontinence. Physiologic findings and outcome of treatment were analyzed based on the categorized groups. Biofeedback therapy by using newly-developed anal sphincter control system (KONTINENCE CLINICAL(TM)) in my institute, was underwent a mean 4.1 (range, 2~12) sessions. The outcome was analyzed in the period of 5.4 (range, 1~33) months follow-up. RESULTS: Patients were categorized as having constipation (group I, n=12) or incontinence (group II, n=6) group. In the manometric parameters, there were no statistical differences between the values of the mean resting pressure (RP), the maximum RP, and the maximum voluntary contraction between group I and II. In the cinedefecography, 3 of group I patients revealed as having the pelvic floor dyssynergia. The findings of PNTML were not specific in group II (n=1). Regarding to the therapeutic outcome, 8 of 10 patients were cured or improved. CONCLUSIONS: There were no differences in the resting and squeeze profiles of manometric parameters between two groups. However, pelvic floor dyssynergia was identified in the cinedefecography of constipated group. Conventional and biofeedback treatment for encopretic children provides acceptable outcome.

Transient hyperkalemia has been reported to occur in eletric burn patients following intravenous administration of succinylcholine. We have studied the origin of the elevated serum K+ concentration after injection of succinylcholine from both the non-burned area and from the burned area in electirc burn patients. Blood samples for serum K+ measurement were drawn 1,2,3,4,5 and 10 minutes after administration of succinylcholine from both the burned are and the non-burned area in 6 electric burn patients. The following results were obtained: 1) Serum K+ levels increased in the burned group in 3 minutes after injection of succinylcholine. 2) The serum K+ concentration of venous samples from the electric burn area were more increased than from the non-burned area injection of succinylcholine.
