This study was performed to observe the therapeutic effects of interferon-gamma(IFN-gamma) and gamma-globulin(gamma-globulin) in experimental Pneumocystis carinii pneumonia of immune suppressed mice. After 9 weeks, trimethoprim-sulfamethoxazole(TMP-SMZ; 10-50 mg/mouse/day), mouse IFN-gamma(5 x 10(4) units/mouse/day) and mouse gamma-globulin(20 mg/mouse/day) were administered to the mice for 3 weeks by the experimental group. The therapeutic efficacy was evaluated by body weights, histopathologic and electron microscopic findings of the lungs, and number of P. carinii cysts by Gomori's methenamine silver stain. Body weights of the mice were significantly increased in the group of combination therapy of TMP-SMZ with IFN-gamma or gamma-globulin, and in the group of TMP-SMZ treatment (p < 0.05), however, little effect was found in the group of gamma-globulin alone. Histopathologic findings of P. carinii pneumonia were much improved in the group of combination therapy of TMP-SMZ with IFN-gamma. Treatment with either TMP-SMZ or IFN-gamma significantly reduced the number of cysts in the P. carinii pneumonia, but gamma-globulin alone was ineffective. In electron microscopic findings of P. carinii pneumonia, the number of trophozoites and cysts were reduced by treatment with either TMP-SMZ or IFN-gamma, and most of the cysts were empty or containing one or two intracystic bodies. The present results suggested, that combination therapy of TMP-SMZ with IFN-gamma had synergistic effects in treatment of P. carinii pneumonia in experimental mice.

It is well-known that the course of phototherapy, stool colour changes from yellow to green. The occurrence of frequent loose green stools, commencing a few hours after the beginning of treatment, has been observed in several different centers. In order to elucidate the machanism by which phototherapy induces loose stools in newborns, studies were perforned on the speed of intestinal transit by performing the carmine red ftest on 15fullterm newborns, 15jaundiced newborns before and after phototherapy and 15 healthy newborns exposed to phototherapy. The following results were obtained. 1) Intestinal transit time in 15 full term newborns was 12.75+_3.54 hours.(Fig. 1). 2) Intestinal transit time before phototherapy was 13.63+_3.21 hours in 15 jaundiced newborns and it was 7.32+_2.76 hours after phototherapy (Fig. 1). 3) Intestinal transit time in 15 healthy newborns was 13.74+_5.14 hours(Fig. 1). A statistically accelerated intestinal transit was observed in jaundiced newborns treated with phototherapy. The increased rate of intestinal transit produced by phototherapy is probably due to the action of the phototherapy.

BACKGROUND: The evaluation of obesity in practice has been done indirectly by anthropometric values such as body mass index(BMI), waist and hip circumferences and waisthip ratio(WHR). Somatotype drawing developed by Srensen has been evaluated as a simple instrument of obesity without real somatic measuring in several studies. This study was attempted to evaluate correlation between somatotype drawing and anthropometric values. METHODS: The subjects were measured anthroprmetric values such as height, weight, hip and waist circumferences. After calculating BMI and WHR, we evaluated correlation between these values and somatotype drawing. And we tried to grouping of somatotype drawing with the means of anthropometric values. RESULTS: The data were collected from 224 subjects, whose BMI(kg/m2) and WHR were 22.81+/-2.96 and 0.84+/-0.07(mean+/-SD). Spearmans correlation coefficients(rs) of somatotype drawing were 0.77 with BMI, 0.62 with waist circumference, 0.61 with weight and hip circumference, 0.40 with WHR that remained statistically significant after adjusting age, sex, education level, monthly income and job. And, the grades of somatotype drawing were grouped as 1, 2, 3-4, 5-6, 7 by BMI and hip circumference, 1, 2-4, 5, 6, 7 by waist circumference(ANOVA and Duncans method). CONCLUSIONS: Somatotype drawing has a good correlations with BMI, weight, waist and hip circumference. But it is not applicable to assess WHR because of its relatively lower correlation.

PURPOSE: Advances in neonatal intensive care have improved the survival rate of low-birth-weight infants, but mild bronchopulmonary dysplasia (BPD) with the accompanying need for prolonged oxygen supplement remains problematic. Maternal chorioamnionitis and neonatal ventilator care affect the development of BPD. This study aimed to examine whether maternal chorioamnionitis or neonatal ventilator care affect the development of BPD dependently or independently. METHODS: We performed a retrospective study of 158 newborn infants below 36 weeks of gestational age and 1,500 gm birth weight admitted to the neonatal intensive care unit of Daegu Fatima Hospital between January 2000 and December 2006. We analyzed the incidence of BPD according to maternal chorioamnionitis and neonatal ventilator care. Result: Histologic chorioamnionitis was observed in 50 of 158 infants (31.6%). There were no significant differences in the development of BPD (P=0.735) between the chorioamnionitis (+) and chorioamnionitis (-) groups. In the multiple regression analysis, ventilator care (OR=7.409, 95% CI=2.532-21.681) and neonatal sepsis (OR=4.897, 95% CI=1.227-19.539) affected the development of BPD rather than maternal chorioamnionitis (OR=0.461, 95% CI=0.201-1.059). CONCLUSION: Ventilator care or neonatal sepsis may play a role in the development of BPD rather than maternal chorioamnionitis.

The myoclonic epilepsies of infancy and early childhood pose the most difficult problems in the diagnosis and classification of epilepsies because they are often confused with the Lennox-Gastaut syndrome sharing a number of common features. However, their correct differentiation is easily justifiable because some of the myoclonic epilepsies of early childhood have better prognosis than the Lennox-Gastaut syndrome. We experienced and treated a 4-year-old boy who had normal intellectual function but frequent myoclonic and generalized clinic-tonic-clinic seizures, which were successfully controlled by anti-epileptic drugs. Hence we report a case with brief review of literatures.

To investigate the retinal hemodynamics in chronic primary open angle glaucoma (POAG), high-quality video fluorescein angiograms using a scanning laser ophthalmoscope(SL0 101, Rodenstock, Munich, Germany) were obtained from 22 eyes of 16 patients with POAG and 14 eyes of 14 healthy subjects. From these angiograms, the arm to retinal time (ART), arteriovenous passage time (AvFT), venous fulling time(VFT) and arteriovenous fulling time (AvFT) were quantified. And these parameters of retinal circulation of the group of patients with POAG were compared with those of the age-matched group of healthy subjects. There were no significant differences in the ART between two groups (p=0.09). But significant prolongations of the AvPT, VFT and AvFT of the group of patients with POAG(2.5 +/- 1.1, 8.4 +/- 1.8 and 10.9 +/- 2. sec, respectively) were observed compared to the values (1.8 +/- 0.7, 6.4 +/- 2.2 and 8.1 +/- 2. 4 sec, respectively) obtained among the healthy subjects (p=0.04, p=0.007 and p=0.0008, respectively). These results indicate that a significant retinal microcirculatory deficit exists in the eyes of POAG, and the VFT and AvFT may be good indices of retinal microcirculatory deficit in the eyes of POAG.

Apoptosis is a distinct mode of cell death that is responsible for deletion of cells in normal tissues. Apoptotic cell death plays an important role in the proliferation and turnover of cells in various tumors. Apoptosis occurs spontaneously in malignant tumors, often markedly retarding their growth, and increased in tumors responding to irradiation, cytotoxic chemotherapy, heating and hormone ablation. Flowcytometric analysis of the cellular DNA content appears to be a useful clinical prognostic indicator in colorectal cancer. The relationship of apoptotic index(AI) and proliferative indices have being investigated. We analyzed the tumor DNA content and AI in 84 patients who underwent resection for colorectal cancer between January 1989 and December 1994 in order to evaluate the prognostic significance of apoptosis, DNA ploidy and index using in situ apoptosis detection method and flowcytometry. The mean value of AI was 32.4, and median value 21. In the cellular DNA, forty-two percent of the tumors were diploidy, fifty-eight percent aneuploidy. The mean value of DNA index(DI) was 1.38, G0/G1 72%, S phase fraction 21.7%, G2/M 6.3%, and proliferative fraction 28%. There was no significant difference between AI and tumor invasion, LN metastasis, DNA ploidy, DI.(p>0.05) There was no significance between overall survival and AI, DNA ploidy, DI. But patients who had tumors with low DNA index had a significantly longer disease free survival than high DNA index.(p<0.05) As a result, this study shows that AI is a less useful as prognostic factor and DNA index is a more important prognostic factor in patients undergoing surgery for colorectal cancer.
