The objective of this study was to establish a good methodology to isolate single smooth muscle cells that are alive and respond properly to pharmacological agents. Canine urinary bladders were employed as the source of single cells, and acetylcholine, atropine and imipramine were used as indicators of pharmacological responsiveness. Imipramine, an antidepressant drug exhibited the anticholinergic and calcium antagonizing properties on rat detrusor muscle. To establish a control value for a further experiment to elucidate the mechanism of action of imipramine on detrusor muscle, we measured the concentration-response of single cells to acetylcholine in the presesnce of imipramine by length of the cells and compared the result with the response in the presence of atropine. Tiny chops of smooth muscle taken from anesthetized canine urinary bladder were incubated in collagenase solution at 36℃ for 17-20 minutes. The collagenase solution included collagenase 1.2 mg/ml, soybean tryspin inhibitory 0.08 mg/ml, bovine serum albumin 2% in 10 ml Krebs-Henseleit buffer solution aerated with a consistent breeze of 95/5% O2/CO2 to maintain the pH at 7.4. After washing with plain K-H solution on 450 mesh, cells were dissociated from the digested tissue for 12-15 minutes. Cell suspension was transfered in 5 ml test tubes and acetylcholine was added for the final concentration to be 10⁻¹⁴~10⁻⁹M. To find the optimal time to fix the cells to determine the contractile responses, 1% acrolein was added 5, 10, 20, 30, 60 and 120 seconds after the administration of ACh. The length of cells fixed by acrolein were measured by microscaler vis CCTV camers on phaes-contrast microscope. The average length of 50 cells from a slide glass was taken as the value of a sample at the very concentration point. Single cells were isolated from canine detrusor. The length of untreated cells varied from 82 µm to 94 µm. The maximal response to actylcholine 10E-9M was accomplished within 5 seconds of exposure, and the shortening was 19±3%. Atropine reduced the contraction of the cells concentration-dependently. Lmipramine which exerts a cholinergic blocking action on some smooth muscles also reduced the contraction concentration-dependently and by a similar pattern as atropine. These findings document that imipramine may exerts a cholinergic blocking activity in the single smooth muscle cells isolated from canine urinary bladder.

Acral persistent papular mucinosis is a subtype of the localized papular mucinosis. Clinically, ivory to flesh-colored papules develop exclusively on the back of the hands, the extensor surface of the wrists, and occasionally the distal forearms. Histologically, mucin accumulates in the upper reticular dermis, typically sparing a subepidermal zone and fibroblasts are not increased in number. On experiencing a case of numerous papules on both hands and forearms of a fifty year-old woman, we present it as acral persistent papular mucinosis.

OBJECT: In order to compare several Obstetric characteristics and outmmes of teenage pregnancy. METHODS: The 10 year clinical records of 11,583 women undergoing Cesarean section and delivery were reviewed in the department of Obstetrics and Gynecology, Incheon Christian Hospital from July 1, 1989 to June 30, 1999. There were seventy-eight pregnancies under age 20 and we compared them with two hundred pregnancies aged 20-29 who were randomly chosen during the same periods as the control group. RESULT: The following results were obtained. The proportion of birth by teenagers increased from 0.5% of all birth in 1989 to 2.61% in 1999. The most of cases were in high teen group, age 14- 19.The majority(50.5%) were in the age of 19. Seventy two cases(92.3%) had no previous pregnant history. Six cases had one previous pregnant history. The frequencies of prenatal care were significantly lower than that of the control group(p<0.05). The mean gestational period was 36+4weeks, and showed significant difference between the study group and the control group(39+3 weeks). The incidence of preterm labor was significantly different between the two proups(p<0.05). But the incidence of postterm delivery were not significantly different between the two groups. The mean weight gain of pregnant teenagers revealed 10.64kg, significantly less profound than the control group. The matemal weight gain of control group revealed 12.95kg, respectively. The mean birth weight(2.54kg) of infant was significantly less profound than the control group. The incidence of birth of small for gestational age(birth weight 1,500-2,499gm ; 14.5%) was significantly increased among study group than the control group(1%). The rate of abdominal delivery(21.8%) were not significantly decreased than the control group(47%). The incidence of cephalopelvic disproportion and malpresentation for cesarean section were somewhat higher than the control group, and were statistically significant(p<0.05). During the antepartun period, anemia, pyelonephritis, and preterm labor occurred more frequently in the teenage pregnancy than the control group, but not statistically significant. Among postpartum complications, incidence of anemia(51.3%) increased significantly. The perinatal mortality, intrauterine growth retardation, congenital anomaly occurred more frequently than the control group. CONCLUSION: These results show that pregnancy of teenage will be comeout high risk and complications. And then we will be more concern and study about teenage pregnancy.

PURPOSE: Specific microorganisms, such as C trachomatis, Mycoplasma and T vaginalis, are rarely detected in idiopathic chronic prostatitis. However, fastidious and nonculturable microorganisms may be important in the etiology of idiopathic chronic prostatitis. The object of this study was to test a new PCR primer set to detect 16S rDNA from various prokaryotes suggestive of the etiologies of idiopathic chronic prostatitis. MATERIALS AND METHODS: A new 16S rDNA primer set was designed from common prokaryotic genetic sequences using bioinformatic tools. The genomic DNAs from E-coli, Enterobacter cloacae, Klebsiella pneumoniae, Pseudomonas aeruginosa, Actinobacter baumanmii, coagulase negative Staphylococcus, Corynebacterium, Serratia marcescens, Proteus mirabilis and Staphylococcus aureus were extracted by boiling colonies from their plated cultures. The template DNAs from the above microorganisms were amplified using this new 16S rDNA primer set. RESULTS: The correct PCR product, 470 bp, was obtained from E-coli, Enterobacter cloacae, Klebsiella pneumoniae, Pseudomonas aeruginosa, Actinobactrer baumanmii, Corynebacterium spp, Serratia marcescens and Proteus mirabilis. However, a constant result from gram positive bacteria, such as Stapylococci, could not be obtained. CONCLUSIONS: A new PCR primer set, which can detect various prokaryotes suggestive of the etiologies of idiopathic chronic prostatitis, was obtained.
