PURPOSE: This study was done to identify the effects of weight-bearing exercise(WBE) on bone metabolism. METHOD: WBE was performed for 12 weeks by healthy college women. Bone-related parameters were measured four times during this period by evaluating the immunoradiometric assay and enzyme immunoassay. Bone mineral densities(BMDs) were measured by dual energy x-ray absorptiometry before and after the WBE program. Data was analyzed using t-test, paired t-test, x2-test, and repeated measures ANOVA. RESULT: Osteocalcin, a bone formation marker, increased more in the experimental group than in the control group based on the interaction between time and group(F=3.29 p=.024). Little difference between the two groups was found for the other parameters: urinary deoxypyridinoline, insulin-like growth factorI, parathormone, serum calcium, and serum phosphorus without showing any time interaction between the groups. The femoral trochanter BMD rose in the experimental group while that of the control group fell, showing a significant difference for BMD(t=3.06 p=.005). However, there was no significant difference between the two groups for changes in BMD of the forearm, lumbar spine, femoral neck, and femoral ward's triangle. CONCLUSION: These findings supported the WBE is beneficial for increasing bone formation in college women and long-term application is needed to substantiate the effects of WBE as a intervention in promotion of bone-health.

Palpation of an abdominal mass in an infant or child presents a challenging problem in diagnosis and treatment. We reviewed the data on 166 patients under age 15 years who admitted to Ped. Dept. of PMC due to palpable abdominal mass in Jan. 1972-July 1977. The results are as follows 1. Of the 57 surgical cases, pathologically confirmed abdominal tumors were 39 cases. Of the 20 retroperitoneal tumors, Wilms tumors were 13 cases, neuroblastomas were 3 cases, polycystic kidney was 1 case, and retroperitoneal teratoma was 1 case. Of the 19 intraperitonel tumors, hepatomas were 3 cases, hepatoblastoma was 1 case, choledocal cysts were 3 cases, mesenteric and omental cysts were 4 cases, malignant lymphomas were 4 cases and ovarian cysts were 3 cases. Other surgical diseases were 2 cases of ascariasis and 2 cases of bezoar. 2. Medical cases were as follows : 35 cases of leukemia, 15 cases of infectious hepatitis, 14 cases of congenital syphilis 7 cases of liver cirrhosis 7 cases of lirerabscesses, 4 cases of miliary Tbc., 3 cases of congenital spherocytosis, 1 case of cryptococosis, I case of osteopetrosis and 1 case of erythroblastosis fetalis. 3. In age distribution, almost all cases(94%) of Wilms tumor and neuroblastoma were under age of 4 and half of medical cases in infancy were congenital syphilis. 4. Of the pathologically confirmed 39 abdominal tumors, 20 cases were retroperitoneal tumor and 19 cases were intraperitoneal tumor. Of the 20 retroperitonel tumor cases, 16 cases were renal origin, 3 cases were adrenal origin, and 1 case was teratoma. Of the 19 intraperitoneal tum orcases, 8 cases were hepatobiliary origin, 3 cases were ovary origin, 4 cases were omental and mesenteric origin and 4 cases were lymphatics origin. 5. Of the 39 abdominal tumor cases, 34 cases (87%) visited the hospital with the chief complaint of palpable abdominal mass. But, of the 94 medical cases, only 16 cases(17%) visited the hospital with the chief complaint of palpable abdominal mass. 6. In some cases presumptive diagnosis on the base of history taking, physical examination, chest X-ray, simple abdominal X-ray. Peripheral blood findings on admission were uncorrect. In 1 case of Wilms tumor, we suspected liver abscess on admission. In 1/3 case of intraperitoneal tumors, we suspected retroperitoneal tumor on admission. We suspected lymphoma on admission in 1 case of ascariasis and 1 case of bezoar. We misdiagnoed 1 case of miliary Tbc. As hepatoma, 1 case of liver cirrhosis as retroperitoneal tumor and 1 case of congenital syphilis as retroperitoneal tumor on admission. 7. In the treatment of malignant abdominal tumor, we tried all possible measures such as surgery, chemotherapy, and radiation therapy. But prognosis of all malignant abdominal tumors were very poor. Only 1 case of Wilms tumor and 1 case of hepatoblastoma were survived at the time of review.

The incidence of diphtheria is markedly decreased in the developed countries. But in Korea, since 1970, there has been an increased incidene of diphtheria and some clinical modifications of the classical picture were seen, such as less incidence of preudomembrane, milder constitutional symptoms and fewer positive culture of C. diphtheriae. With this in mind we reviewed the 40 cases of diphtheria, who were admitted to Ped. Dept. of PMMC during the period of past 5 years period(Feb. 1972-Dec. 1976). Thus this study is based on the clinical manifestations, the findings of routine lab. And EKG, localization of diphtheric lesions, relationship between the first visit to hospital and death rate, and the various complications of the disease esp. toxic myocarditis. The results of this study are as follow: 1. Number of patients had been increased since 1974. The 70% of diphtheric cases was developed in Winter season. 2. The age incidence was highest in the 4~8 years range and 14 cases (35%) were before 6 years of age. The sex ratio of male to female was 1.5:1. Primary DPT vaccination had been done in only 1 case. 3. The average time coming to the hospital was 5.4 days of illness. Patients with laryngeal type visited hospital earlier than patients with pharyngeal type. 4. The site of localization of diphtheria was larynx (42.5%), pharynx (37.5%), and pharyngolarynx (20%). 5. The chief clinical findings on admission was dyspnea (70%), fever (67.5%) and pseudomembrane (30%). There were marked difference in clinical manifestations with the site of localization of the disease. 6. Leucocytosis was found in almost every case. Culture studies for Corynebacterium diphtheriae were positive in 72.5% of cases. 7. The order of EKG abnormalities were S-T segment and T-wavechanges, complete A-V block, A-V dissociation, P-R interval prolongation, and right bundle branch block. 8. Complications of the disease were as follows : Bull neck (20%), myocarditis (30%), peumonia (27.5%), and proteinuria (42.5%). 9. Mortality rate was 15% of the total, 20% in pharyngeal type, 25% in pharyngolaryngeal type and 7% in laryngeal type. The cause of death was myocarditis in 5 case and pneumonia in 1 case. The mortality rate of myocarditis was 42% ( 5/12).

In effort to determine whether aircraft noise can have health effects such as hearing loss, hypertension and psychological stress, a total of 111 male professors and administrative officers working a college near a military airport in Korea(exposed group) and a total of 168 males and 112 females matched by age groups(control groups) were analyzed. Personal noise exposure and indoor and outdoor sound level of jet aircraft noise were measured at the exposed area. And pure tone, air conduction test and measurement of blood pressure were given to the exposed(males) and matched control groups(males and females). BEPSI(Brief Encounter Psychological Instrument) and psychological response to aircraft noise were examined for the exposed group. The noise dosimetry results revealed time-weighted averages(TWAs) that ranged from 61 to 68 dBA. However the levels encountered during taking off jet airplanes reached 126 dBA for two half minutes time period. The audiometric test showed that mean values of HTL(hearing threshold level) in exposed group at every frequency(500, 1,000, 2,000, 4,000, and 8,000 Hz were much lower than them of male and female control groups. And in old age groups, interaction of age and noise was observed at 8,000 Hz in both ears(p< 0.05). Conclusively, aircraft noise does not appear to induce hearing loss directly, but may decreased hearing threshold level by interaction of aging process and noise exposure. However, difference of mean values of exposed and control groups on blood pressure was not significantly. In psychological test, annoyance was the most severe psychological response to noise in exposed group, but mean value of BEPSI was not correlated with job duration in exposed group

BACKGROUND: Inflammatory bowel disease(IBD) such as ulcerative colitis or Croln's disease is often related with varied diseases including pyoderma gangrenosum, erythema nodosum, ankylosing arthritis and psoriasis. To date, however, a cIinical observation of IBD accompanied by psoriasis has been sparcely accomplished although an immunogenetic mechanism explaining a coexistence of IBD and psoriasis has been proposed. OBJECTIVE: We estimated the prevalence of IBD in patients with psoriasis in Korea and investigated the clinical characteristics of IBD accompanied by psoriasis. METHODS: 92 psoriatic patients and 389 non-psoriatic control subjects were enrolled in this study. Colonoscopic biopsy and barium series were performed in 47 psoriatic patients and 110 control subjects showing irritative intestinal symptoms. RESULTS: 1. The prevalence of IBD in psoriatic patients(14.1%) was significantly greater than in the control group(1.0%). 2. In the temporal relationship, psoriasis developed several years prior to the onset of IBD in 84.6% of psoriatic patients. 3. The frequency of arthropathies in the psoriatic patients possessing IBD(84.6%) was significantly higher than that of non-psariatic counterparts with IBD(25.0%) or that of psoriatics without lBD(2.5%), 4. The psoriatir. patients with IBD demonstrated much more frequently diffuse colonal extension than in non-psoriatic subjects with IBD. CONCLUSION: Our findings of an increased prevalence of IBD in the psoriatic population present further evidence of an association between IBD and psoriasis. In the psoriatic patients showing acute or chronic gastrointestinal symptoms, colonoseopic evaluation might be mandatory for the evaluation of IBD.

Recently apoptotic cell death has been reported in differentiated skeletal muscle, where apoptosis was generally assumed not to occur. To investigate whether apoptosis may contribute to the steroid-induced myopathy, rats treated with triamcinolone acetonide (TA) for 9 days were sacrificed for detecting apoptosis by in situ end labeling (ISEL) and electron microscopy in the soleus muscles. Immunohistochemical stainings of Fas antigen and p53 protein were performed to examine whether apoptosis-related proteins were present in the myopathy. Muscle fiber necrosis and apoptotic myonuclei appeared in the soleus muscles following administration of TA, while control muscles showed no evidences for apoptosis. Fas antigen was not detected in control muscles, but expressed in the soleus muscles of steroid-induced myopathy. Some of the Fas antigen-expressing muscle fibers were positive for ISEL. p53 protein was not detected in any muscle fibers. These findings indicate that TA can induce apoptosis in differentiated skeletal muscles, and Fas antigen might be partly related to apoptotic muscle death in steroid-induced myopathy.

The aim of this study was to evaluate neurotoxicity of Nitric oxide(NO) on cornea after excimer laser photorefractive keratectomy(PRK). PRK was performed on rabbit eyes. According to the time table, tear samples were collected with microcapillary tubes and corneal sensitivity was measured with a Cochet-Bonnet esthesiometer. No generation in the tear fluid was analyzed. To demonstrate NO Synthase(NOS), immunohistochemical localization was performed on frozen sections from rat eyeball tissue. Western blot analysis was used for detection of peroxynitrite, powerful oxidant of NO. NO generation was increased and reached to a maximum value(0.69+/-0.22micrometer/microgram) after 96 hours of PRK, as compared with in normal subjects(Mean: 0.30+/-0.08micrometer/microgram) and was not increased in the treated group with topical application of Ng-nitro-L-arginine methyl ester(L-NAME), a competitive inhibitor of constitutive NOS(cNOS) and inducible NOS(iNOS). Corneal sensitivity decreased below pretreatment levers after three postoperative days, but it was not observed in the L-NAME applied group. We have confirmed that a very strong iNOS and BNOS immunoreactivity was present in corneal keratocytes. Western blot analysis identifed the bands of nitrotyro-sine-proteins suggesting in vivo peroxynitrite toxicity. Our results suggested that NO generated from the enzyme after PRK decreased corneal sensitivity by damaging corneal sensory nerve through the NO and iths oxidant peroxitrite. Therefore topical application of a NOS inhibitor may be effective in maintaining corneal sensitivity.
