PURPOSE: Relaxation of the penile cavernosum smooth muscle is a critical event in erection. Artemisia iwaymogi(AI) is a perennial herb growing in Korea. The aerial parts have been used in folk medicine. Bioassay-guided fractionation of an H2O extract of AI has furnished an inhibitory substance (PCLS-2). We investigated compound extracted in the rabbit corporal cavernosum smooth muscle. MATERIALS AND METHODS: Bioassay-guided fractionation of an H2O extract was used. A strip of rabbit corpus cavernosum was mounted in an organ chamber to measure the isometric tension. PCLS-2 compound induced relaxations were evaluated by in vitro study using muscarinic receptor blocker atropine (ATR), cyclo-oxygenase inhibitor indomethacin, nitric oxide synthase (NOS) ihibitor Nitro-L Arginine-Methyl Ester (NAME), guanylate cyclase inhibitor 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin 1-one (ODQ), intrinsic neurotransmission inhibitor tetrodotoxin (TTX), or/and potassium channel blockers. RESULTS: PCLS-2 showed relaxation in a dose-dependent manner. Atropine, Indomethacin, NAME, ODQ, TTX, glibenclamide, tetraethylammonium, 4-aminopyridine, charybdotoxin, or apamin did not inhibit the relaxation induced by PCLS-2 compound. CONCLUSIONS: The present results suggest that the PCL-2 compound has effect of relaxation of corpus cavernosum smooth muscle and the relaxation was not involved muscarinic receptor, nitric oxide, prostaglandin, potassium channels and intrinsic neurotransmission. Other mechanisms may by involved in the PCLS-2 induced relaxation in the rabbit corpus cavernosum smooth muscle.

We experienced a case of primary gastric tuberculosis presented with melena. A 61-year-old male was admitted with epigastric pain and melena. Upper endoscopy revealed an irregular shaped gastric ulcer on the posterior wall of the body. Histological examination of endoscopic specimen revealed chronic inflammation with fibrosis, granulomas and acid-fast bacilli. Cultures for acid-fast bacilli subsequently grew Mycobacterium tuberculosis. There was no evidence of the tuberculous lesion anywhere else. Primary gastric tuberculosis remains an extremely uncommon clinical entity; the definitive diagnosis is made by biopsy and positive culture for the organism. We report a case of primary gastric tuberculosis with review of the literature.

Most nontraumatic subarachnoid hemorrhages are induced by the rupture of a saccular aneurysm. Acute nontraumatic cortical subarachnoid hemorrhage at the convexity of a cerebral hemisphere is a relatively rare occurrence with various vascular or nonvascular causes. Furthermore, the clinical manifestation of acute nontraumatic cortical subarachnoid hemorrhage differs from that of aneurysmal rupture. We experienced five cases of acute nontraumatic cortical subarachnoid hemorrhage with diverse neurological symptoms. Consecutive workup revealed the various etiologies of that hemorrhage.

Postpartum cerebral angiopathy is a main cause of postpartum stroke. We describe a 27-year-old woman with postpartum cerebral angiopathy after taking bromocriptine. Her brain FLAIR MR image revealed several lesions of sulcal hyperintensity. The sulcal hyperintensity in the MR image may be a sequelae of bromocriptine-induced angiopathy during the postpartum period.

BACKGROUND: Gallstone is the most common disease of the biliary system. Most cases of gallstone are asymptomatic and we incidentally found gallstones during a community health survey. Our study was designed to determine the prevalence and risk factors for gallstone in a population who underwent health screening. METHODS: We enrolled a total of 36,314 persons who visited the health promotion center in Kyungpook National University Hospital in Korea from 1998 to 2004. They had their gallbladder or biliary system examined with using ultrasonography. The body mass index and biochemical parameters from liver function tests, the lipid profiles and the fasting blood sugar were all measured. All the subjects were divided into several groups and the particular prevalence for gallstone disease for each group was calculated. Chi-square tests and logistic regression analysis assessed the risk factors for gallstone disease. RESULTS: Among 36,314 persons, (19,345 males (53.3%) and 16,969 females (46.7%)), gallstone was found in 735 persons (2.0%). On univariate analysis, the risk factors for gallstone disease were age, body mass index, fasting blood sugar, total cholesterol, LDL-cholesterol, triglyceride and serum aspartate aminotransferase. On multivariate logistic regression analysis, the the risk factors were high body mass index, older age and high fasting blood sugar. CONCLUSIONS: The risk factors seem to show a common pathogenesis for gallstone disease. Although the relation between gallstone disease and metabolic syndrome has not been established, it appears to be associated with metabolic syndrome, but further study on a general population is required.
