We studied the left ventricular function with the use of M-mode and 2-D Echocardiography to 32 patients with congestive heart failure before and 2 weeks after medication of prazosin 2 mg tid during July 1979 and Dec. 1980 in Heart Center, Paik Hospital, In-Je Medical College, Busan, Korea. The results were following; 1) LVDeD before and after vasodilaor therapy was each 5.64+/-0.76 and 5.04+/-0.57.cm, LVSeD before and after therapy each 4.52+/-0.51 and 3.70+/-0.57cm, and F.S. before and after therapy 19.87+/-3.66 and 26.59+/-6.75%. The difference of LVSeD, LVDeD and F.S. was each statistically significant. 2) LVDeV before and after therapy was each 182.2+/-58.07 and 132.80+/-47.01 ml LVSeV before and after therapy each 92.35+/-23.60 and 50.65+/-27.21ml, and E.F. before and after therapy each 49.31+/-7.07 and 61.86+/-11.74%. The difference of LVDeV, LVSeV and E.F. was each statisitically significant. 3) LVPWTh before and after therapy was each 0.89+/-0.11 and 0.77+/-0.08cm, and Vcf before and after therapy 0.83+/-0.11 and 1.03+/-0.27 cir./sec. The difference of LVPWTh and vcf before and after therapy was each statistically significant. 4) The difference of VSTh, RVD, LAD, and Aorta Dimension before and after therapy was each statisitically significant.

BACKGROUND: Recently, missense mutation of the B3-adrenergic receptor gene has been shown to be associated with early onset of type 2 diabetes, abdominal obesity and an increased capacity to gain weight. This study was performed to investigate the effects of Trp64Arg mutation in the B3-adrenergic receptor gene on body fat distribution and weight loss in obese subjects. METHODS: Determination of the B3-adrenergic receptor gene mutation with restriction enzyme digestion method, anthropometry, various biochemical studies, including oral glucose tolerance test were performed in 99 obese and 35 control subjects. Body fat distributions were also evaluated by computerized tomography before and after weight-reduction program. RESULTS: I) There were no differences in the frequencies of Trp64Arg mutation in the B3-adrenergic receptor gene between obese and control subjects (15.2 vs 12.9 %). 2) The obese subjects with Trp64Arg mutation had higher waist to hip circumference ratio(WHR) (0.93 +/- 0.05 vs 0.87 +/- 0.04, p<0.001), visceral fat area (115.0 +/- 25.9 vs 86.4 +/- 41.4 cm, p=0.01), but decreased plasma free fatty acid (618.0 +/- 163.1 vs 817.5 +/- 248.2 pEq/L, p=0.001), and triglyceride level (118.7 +/- 36.2 vs 158.4 +/- 105.8 mg/dL, p=0.015) than those without mutation. 3) The obese subjects with Trp64Arg mutation had smaller decreases in weight (-3.4 vs -5.1 kg, p<0.001), body fat content (-2.1 vs -3.8 %, p<0.001), WHR (-0.01 vs -0.03, p=0.025), and abdominal fat masses (total, subcutaneous, and visceral fat) after weight-reduction program than those without mutation. CONCLUSION: Trp64Arg mutation in the B3-adrenergic receptor gene might be one of genetic loci contributing to central obesity and a predictor of difficulty in losing weight in obese subjects.

Hepatoma is one of the most common malignant disease among cancers that occur in Korea. Recently, according ta developing imaging diagnostic technology and non surgical treatment the hepatoma is easily detected in early diagnosis and appropriate treatment. From this point of view, the histologic pattern of hepatoma is markedly important. This is the first reported case of sclerosing hepatocellular carcinoma, which is characterized by intense fibrosis, in which the tubular neoplastic structures are embedded. The incidence of sclerosing hepatocellular carcinoma is very rare. Therefore the rare histologic pattern of hepatoma might be introduced by many studies and reports. We recently experienced a case of sclerosing hepatocellular carcinoma.

The relationship between hypercalcemic crisis and pancreatitis, first described in patients with hyperparathyroidism, still remains controversial. Acute pancreatitis may complicate the clinical course of hyperparathyroidism, particularly when the degree of hypercalcemia is severe. The incidence of hyperparathyroidism presenting as acute pancreatitis appears to be steadily decreasing, possibly reflecting the earlier diagnosis of asymptomatic hyperparaparathyroidism due to widespread application of screening methods. Here, we report two patients with primary hyperparathyroidism manifesting clinically as acute pancreatitis. One patient died of progessive pancreatitis and uncontrolled sepsis. The other patient was fullly recovered by emergent parathyroidectomy followed by medical management of hypercalcemia.

Background: Estrogen status is important for maintaining the homeostasis of bone. Estrogen has direct effects on bone cells, through binding to the high-affinity estrogen receptor. Several recent studies suggest that there might be genetically determined variations in biosynthesis and function of estrogen receptor in postmenopausal osteoporosis. Also the main cause of postmenopausal osteoporosis is decreased level of serum estrogen, whereas there had been some suggestion that the remaining estrogen have some effect on bone metabolism after menopause. We investigated the relationship between estrogen receptor gene PvulI polymorphism and bone mineral density(BMD), and the relationship between 18 urinary metabolites of estrogen and BMD in Korean postmeno- pausal osteoporosis. Methods: We examined the PvuII polymorphism of the estrogen receptor gene in 5' upstream region and the first intron by restrietion frapnent length polymorphism analysis in 62 postmeno- pausal wornen, BMD was measured by DEXA. The urinary estrogen metabolites were determined by GC/MS(Gas Chromatography-Mass Spectrometry) at Korean Institute of Science and Techno- logy Doping Control Center. Results: BMD of the spine and the femoral neck correlated with body weight, height, body mass index as we expected. There was no polymorphism of PvuII restriction site on 5 upstream region of estrogen receptor gene. Whereas the prevalen~ee of the PP, Pp, pp genotype in the first intron of estrogen receptor was 12.9%, 45.2%, 41.9%, respectively. But, there was no correlation between PvuII genotype and the spinel and femoral neck BMD. 2(OH)E2 among 18 urinary metabolites of estrogen, showed a negative correlation with the spinal and femoral neck BMD(r =-0.2551, p<0.05, and r =-0.3341, p<0.01, respectively), and the ratio of 16a(OH)E2/2(OH)E1> revealed a positive correlation with the spinal BMD(r =0.3057, p<0.05). In stepwise multiple regression analysis, body weight, 2(OH)E2, 16a(OH)E1, 2(Meo)E1 were independent predictors of the spinal bone density, and body weight and 2(OH)E2 were independent predictors of the femoral neck bone density. Conclusion: These results suggested that restrietion fragment length polymorphism analysis of the estrogen receptor gene with PvuII restriction enzyme was not helpful for early detection of patients at risk of developing osteoporosis. However, the ratio of 16-hydroxylation to 2-hydroxylation of estrogen metabolism was reduced in postmenopausal women and high catecholestrogen formation might be a greater risk factor for osteoporosis.
