Acute intermittent porphyrla(AIP) is a disorder that results frorn partial deficiency of porpbobi- linogen dearninase an has varlable clinical manifestations, such as acute abdominal pain, vomiting, nausea, constipation, perlpheral neuropathy, seizure, abnormal psychic symptoms, respiratory failure, tachycardia, and hypertension. If cases present severe acute hypertension, their clinical signs may mimick pheochromocytoma and the diagnosis of AIP would be delayed. We experienced a case of acute intermittent porphyria presenting with acute hypertension, mimicking pheochromo- cytoma in a 35 year-old female patient. She had history of two admissions to different hospitals with acute hypertension and abdominal pain. An extensive investigations had been done but no specific diagnosis was made. She had previously responded well to atenolol but after continuous treatement this led to hypotention. Her blood pressure was 210/140mmHg in both arms at admision to this hospital. She complained of acute abdominal pain and constipation, and she also had psychotic episodes. She had intermittent severe hypertension with the feature of pheochro- mocytorna. Tests for pheochromocytoma(including 24h urinary catecholamines, clonidine-inhibition test) were negative. Apart from slightly increased urinary excretion of catecholamines on one occasion, her symptoms were provoked by starvation and emotional stress and neurologic exami- nation revealed peripheral neuopathy. A screening test for porphobilinogen was strongly positive, but tests for uroporphyrin and coproporphyrin were negative. AIP was confirmed by clinical features and increased 24 hour urine delta-aminolevulinic acid(60.2 mg/1). Also, screening test for porphobilinogen was strongly positive in her mother and her brother. Supportive treatment with high glucose solution infusion and cimetidine resulted in symptomatic recovery and she was discharged after being educated on precipitating factors. The presenting feature of acute hypertension in this case baffled several doctors and the diagnosis of AIP was long delayed. AIP should be considered as one of the differential diagnosis of acute hypertension, especially when pheochrornocytoma is suspected but cannot be demonstrated.

N/A Objective: Anti-neutrophil cytoplasmic antibody (ANCA), known as a useful diagnostic marker in patients with ulcerative colitis (UC), are specific for granule proteins of granulocytes and monocytes and induce distinct fluorescence patterns. To evaluate the significance of ANCA in chronic inflammatory bowel disease (IHD), the presence of ANCA in chronic IBD was studied using indirect immunofluorescent test (IIF), Methods: Between March, 1994 and September 1995, 51 patients with chronic inflammatory bowel disease were subjected in this study. We had analysed the correlation between duration, disease activity, location by colonoscopy and radiologic examinations, steroid treatment. Results: 1) Among 34 patients with ulcerative colitis (UC), ANCA was demonstrated in 23 patients (67.6%). Among 19 patients with other chronic IBD (4 Crohn's disease, 6 Behcet's colitis, 7 intestinal tuberculosis and 2 radiation colitis) 2 patients (10.5%) had ANCA. The positivity of ANCA in patients with UC was significantly higher than in patients with other chronic IBD. 2) In patients with UC, c-ANCA was positive in 2 (5.9%) patients and p-ANCA was positive in 21 (61.8%) patients. In patients with other chronic IBD, ANCA was positive in one patient with Behcet's colitis or one patient with intestinal tuberculosis but negative in all patients with Crohn's disease or radiation colitis. 3) The mean duration of disease in ANCA positive patients was 42.4±39.4 months and the mean duration of disease in ANCA negative patients was 44.9±36.8 months, but there was no significant difference. 4) The number of patients in clinically mild, moderate and severe group were 23 (37.6%), 6 (83.2%) and 5 (14.7%) respectively. Among these groups the number of ANCA positive patients were 15 (65.2%), 5 (83.2%) and 3 (60%) respectively, but there was no significant difference. 5) The number of patients with proctitis, left side colitis and pancolitis were 9 (26.5%), 14 (41.2%) and 11 (32.4%) respectively, Among these groups the number of ANCA positive patients were 4 (44.4%), 10 (71.4%) and 9 (81.8%) respectively, but there was no significant difference. 6) Among 13 patients with steroid treatment 9 patients (69.2%) were ANCA positive. Among 21 patients without steroid treatment 16 patients (76.2%) were ANCA positive, but there was no significant difference. Conclusion: Although there was no correlation between ANCA and duration, disease activity, location or steroid treatment in UC patients, ANCA could be a diagnostic marker of UC in chronic IBD patients.

N/A The spastic pelvic floor syndrome is a functional disorder due to abnormal contraction in- stead of relaxation of the pelvic floor muscle during straining. This inhibits defecation and gives rise to constipation. We carried out the clinical and psychologic analysis, defecogram, electrophysiologic tests, and treatment in 17 patients with spastic pelvic floor syndrome. The mean age of patients was 48.2+10.1 years. The male to female ratio was 1:7.5. Prirnary com plaints were incomplete evacuation 82.3%, constipation 52.9%, tenesmus 41.2%, straining 41.2 %, and dysuria 29.4%. The patterns of personality using the MMPI showed somatization type in 7 cases and psychophysiologic reaction type in 4 cases. Defecogram revealed paradoxical contraction of puborectalis in 100.0% of cases,incomplete evacuation 76.5%, rectocele 58.8%, incontinence 17.6%, intussusception 5.9%, and excessive pelvic floor descent 5.9%. The ano- rectal angle in patients did not increase during straining and rernained about 90. The mean maximum resting and squeezing anal canal pressures were 94.4 + 48.4mmHg, and 136.4 + 28.8 mmHg. Seven patients(70.0%) were unable to expel a balloon. The pudendal neuropathy re- vealed in 4 patients(40.0%). Seven patients underwent a EMCr-based biofeedback therapy. Four among them(57.1%) had increased bowel frequency and improved the symptom of in- complete evacuation. In conclusion, careful history taking, physical examination and colorectal motility tests perrnit diagnosis of spastic pelvic floor syndrome. This disease is related with incoordination of pelvic floor muscle, so treatment should be aimed at restoration of normal muscle function through biofeedback.(Korean J Gastroenterol 1994; 26: 482 490)

This experiment was carried out to compare biological availability of phosphorus(P) in locally produced dicalcium phosphate(DCP), tricalcium phosphate(TCP) and sodium acid phosphate (SAP) with 210 broiler-type chicks(Arbor Acres). Chicks were divided into 7 treatments consisted of DCP_1(low), DCP_2(high), TCP_1(low), TCP_2(high), SAP_1(low), SAP_2(high) and Control group for a period of 4 weeks. The results obtained are summarized as follows: 1. Liveability of Control, DCP_1, DCP_2, TCP_1, TCP_2, SAP_1 and SAP_2 were 90.0%, 96.7%, 96.7%, 93.3%, 93.3% 96.7% and 96.7%, respectively. 2. Body weight gain, feed intake and feed efficiency for 4 weeks feeding period were not significantly affected by the source of phosphorus supplements. However, it was found that chicks received DCP gained more body weight than the birds fed TCP or Control diet. 3. The relative biological availability of P in DCP, TCP and SAP fed broiler chicks were 98.1%, 94.23% and 100%, respectively. The results obtained from the present experiment indicated that the availability of P in DCP were better than that in TCP.

Eighteen Holstein cows capable of producing at least 23㎏ of milk per day were assigned randomly in equal numbers and fed one of three isocaloric total rations of 15.8 (soybean meal), 15.8 (urea), or 14.1% (urea) crude protein in dry basis. All cows were fed their assigned ration continuously for 63 days beginning on the 20 day postpartum. This experiment was designed to determine the influence of concentration and source of dietary protein on milk production(kg) and milk fat(%) during early lactation. The results which were obtained in this experiment as follows: 1. Milk yields (4.0% fat corrected milk, FCM) of cows for 42 day trial in early lactation were 23.80, 20.32, 18.44kg for the respective treatment. In this experiment the higher protein concentration (15.8% vs 14.1%) increased milk production, and source of protein influenced milk production. 2. Milk fat of 3.63, 3.52, and 3.39% showed that dietary protein concentration and source influenced milk fat in early lactating cows. 3. Income above feed cost for 42 day trial was greatest for the group fed the 15.8% crude protein from soybean meal (5,406 won/cow/day) and lowest for the group fed the 14.1% crude protein from urea (3,919.5 won/cow/day). income above feed cost for 15.8% crude protein from urea was 4,154.4 won /cow/day.

Pituitary metastais is a rare condition of distant metastasis of systemic cancer. Pituitary metastasis may present headache, hypopituitarism, and diabetes insipidus resulting from metastatic site. We report a 42 year-old man with pituitary metastasis from periampullary adenocarcinoma who developed diplopea follwing headache and importence. He also had widespreak lymph node metastasis. Diagnosis was made by endoscopy with biopsy, abdominal ultrasonogram, abdominal CT scan, and brain CT scan. Brain CT scan showed tumor in the pituitary gland with invasion into sphenoid bone and cavernous sinus. Light microscopic fingdings revealed moderately differentiated adenocarcinoma in periampullary mass, and metastatic adenocarcinoma in the cevical lymph node. The combined pituitary stimulation test showed decreased reserve capacity of pituitary hormones. We report a case of pituitary metastasis from periampullary adenocarcinoma with the revies of the literature.(J Kor Endocrino 8:88~93, 1993)

We reviewed 21 surgically and 17 percutaneously drained abdominal abscesses at Yong Dong Severance Hospital, Yonsei University College of Medicine from March 1983 to January 1990. The results were as follow: 1) The most common location of abscesses was right paracolic (25.0%), followed by subhepatic (22.2%), right subphrenic (19.4%), left subphrenic (19,4%) and lesser sac space (11.1%). 2) The most common causative aerobic microorganism was E. coli, followed by Streptococcus, Enterococcus, Klebsiella and the most common anaerobic microorganism was Bacteroides fragilis, followed by Peptostreptococcus, Bifidobacterium. 3) The most common cause of pyogenic abscesses was postoperative complication (58.3%), followed by original intraperitoneal disease without operation (22.2%), trauma (5.6%). 4) Among the total 36 cases, we had 95.2% success rate with 21 cases drained surgically, 76.4% success rate with 17 cases drained percutaneously. We conclude that if percutaneous drainage is possible, percutaneous drainage under US or CT guide is an effective method for treatment of intraabdominal abscesses and avoids the risks of a major operative procedure.
