This study is aimed to observe the expressions of different genes, including the extracellular matrix proteins, growth factors, and transcription factors during different developmental stages of mouse submandibular gland. Reverse transcription-polymerase chain reaction (RT-PCR) and the antisense inhibition in organ culture system were performed using mouse embryos and newborns. Total 140 mouse embryos (E14(80), E15(20), E16(20), E18(20)) and 30 newborn mice (D2(10), D3(10), D6(10)) obtained from 60 pregnant mice and 3 adult mice (3 weeks old) were used for the cDNA production and the salivary gland organ culture. Syndecan, perlecan, laminin alpha1 chain, TGF beta1, beta 3, and sonic hedgehog mRNAs were expressed in the early stage (E14~E16) of the submandibular gland development, whereas transglutaminase C (TGase C), E-cadherin, epimorphin, laminin beta2 and gamma1 chains, and HGF mRNAs were expressed in the middle and late stages (E16~E18, D2~D6). Antisense inhibition of different genes in the organ culture of E14 mouse embryos of submandibular gland showed specific growth retardation in the development of ductal and acinar cells. Especially, the antisense inhibition of perlecan, E-cadherin, laminin alpha1 chain, laminin beta2 chain, and syndecan mRNA arrested the growth of ductal and acinar cells. While the antisense inhibition of integrin beta5 greatly affected the acinar cell differentiation and also produced cystic dilatation of salivary ducts, the antisense inhibition of fibronectin showed aberrant growth of ectomesenchymal tissues of the mouse submandibular gland.

BACKGROUND: In order to evaluate the prevalence of enterovirus and cytomegalovirus infections to terminally failing hearts, the presence of enteroviral RNA and cytomegaloviral DNA was screened in the explanted hearts of transplantation recipients. METHODS: RNA and DNA extractions were performed from explanted failing hearts (N=22) and normal hearts (N=5). Reverse transcription-polymerase chain reaction (RT-PCR) of enterovirus and polymerase chain reaction (PCR) of cytomegalovirus were performed. In situ RT-PCR and in situ PCR were performed with positive nucleic acids of viruses. RESULTS: The positivity of enterovirus in failing hearts was 4.4% (1/22) and 0% (0/5) in normal hearts in nested RT-PCR. There was no significant difference in positivity of enteroviral RNA between failing and normal hearts. Nuclei of myocardium was stained in dark-violet color with in situ RT-PCR. The positivity of cytomegalovirus in failing hearts was 45% (10/22) and 40% (2/5) in nested PCR. There was no significant difference in positivity of cytomegaloviral DNA between failing and normal hearts. Nuclei of myocardium was stained in dark-violet color with in situ PCR. Positive chambers of cytomegalovirus were in decreasing tendency according to increasing patient's age. CONCLUSION: Enterovirus was very rarely observed in explanted terminally failing hearts and cytomegalovirus was frequently found both in explanted failing hearts and normal. These viruses have little direct causal relationship with the development of heart failure.

The authors analysed 261 cases of mycoplasmal pneumonia in children who were admitted to the pediatric department of Seoul Adventist Hospital between July 1986 and June 1991. The result obtained were as follows; 1) Yearly distribution of the cases showed high in 1987 and 1991, but no significant difference was noted in seasonally or monthly distribution. 2) The peak incidence of age was between 2 and 6 years of age, and the sex ratio of boy to girl was 1.1:1. 3) pulmonary manifestations were asthma in 21 cases (8.0%), atelectasis in 5 cases (1.9%), emphysema in 3 cases (1.2%), pleural effusion in 16 cases (6.1%), otitis media in 4 cases (1.2%) and sinusitis in 9 cases (3.4%). 4) Extrapulmonary complication were hepatitis in 53 cases (20.3%), skin rash in 9 cases (2.4%), proteinuria in 6 cases (2.3%), and hematuria in 4 cases (1.5%). 5) On the chest X-ray examination, the most common type of pneumonia was interstitial pneumonia (94 cases, 39.8%), and unilateral involvement was common (85.6%), and the most common involvement was right lower lobe (83 cases, 41.4%). 6) The relationship between the type of pneumonia and cold agglutinini titer, and between the type of pneumonia and Mycoplasma antibody titer were not found (P>0.05). 7) In the 16 cases of pleural effusion, The type of pneumonia was lobar, lobular (9 cases), bronchopneumonia (7 cases), and interstitial type was not present. The site of pneumonia was left (6 cases), right (9 cases), and 1 case showed bilatrality. The extent of pleural effusion was mild (10 cases), moderate (3 cases), and severe (3 cases). The result of pleural fluid exam in severe cases was all exudate. 8) The mean duration of admission was most common from 6 to 10 days. the mean duration of admission by the type of pneumonia was lobar, lobar (10.71+/-3.40), interstitial (8.78+/-2.14), and bronchopneumonia (8.83+/-2.47). 9) Both mycoplasma antibody test and cold agglutinin test were carried out in 185 cases and sensitivity of mycoplasma antibody test was 55.1%.

PURPOSE: This study was a latitudinal descriptive effort to understand the degree of quality of life of patients who had undergone a rectal cancer operation. METHODS: The Korean versions of European Orgaization for Research and Treatment of Cancer (EORTC)-Quality of life Questionnaire 30 (QLQ-C30) and Colorectal Cancer-specific Core Questionnaire (QLQ-CR38) were used to examine the degree of quality of life of patients who had undergone a rectal cancer operation. The subjects of this study were 155 patients who had been diagnosed as having rectal cancer and who had received an anterior resection (AR), a low anterior resection (LAR), or an abdominoperineal resection (APR). RESULTS: In our study, patients' responses were combined and converted to a 0-100 scale according to the guidelines provided by the EORTC Center. From these guidelines, high functional scores (0-100) represent good function and high symptom scores (100-0) signify more problems. The APR patients had their social and family life disrupted (social functioning) and were less able to get about and look after themselves (physical functioning), and they felt themselves to be less attractive (body image). In addition, the scores for stoma problems were worse than those for pain and for male sexual problems. The AR patients and the LAR patients, despite suffering diarrhea, symptoms of insomnia, and defecation problems, had better quality of life than the APR patients without anorectal function. CONCLUSION: If the quality of life of rectal cancer patients is to be maintained and their rate of survival is to be increased, an understanding of the patients' situation, education on self-management related to stoma, and active provision of support from medical teams to solve the discomfort caused by the operation are needed.

PURPOSE: To evaluate prognostic factors for improvement of visual acuity after intravitreal triamcinolone acetonide injection (IVTA) for treatment of macular edema (ME) secondary to branch retinal vein occlusion (BRVO). METHODS: Sixty-eight eyes of 68 consecutive patients treated with IVTA for ME due to BRVO were retrospectively reviewed. Patients were categorized into 2 groups according to the final visual acuity. The 'gainer group' consisted of eyes with a gain of 2 or more Snellen chart lines and the 'non-gainer group' consisted of eyes with less than 2 lines improvement or which had worsened at the last follow-up visit. Comparative clinical characteristics and ophthalmoscopic examinations were analyzed between the 2 groups. RESULTS: Out of the 68 eyes, 38 (56%) showed improved vision and were categorized as the gainer group; 30 eyes (44%) were categorized as the non-gainer group. The duration of symptoms in the non-gainer group was longer than the gainer group. Additionally, patients with a better baseline vision were expected to show greater improvement. The number of early visual acuity gainers who showed visual improvement at 1 month after IVTA was significantly higher in the gainer group. The number of eyes with angiographically documented macular ischemia was significantly higher in the non-gainer group. Existence of subretinal fluid has been identified as a positive factor for visual improvement. CONCLUSIONS: The cases with early treatment, good baseline visual acuity, case of favorable response to the initial IVTA, absence of macular ischemia, and baseline subretinal fluid are favorable prognostic factors for the outcome of visual acuity after IVTA for ME due to BRVO.
