The tuberculosis of the stomach is very rare disease and its association with gastric carcinoma is more so. The diagnosis of gastric tuberculosis is usually made on the histological basis not clinical findings. This case of gastric tuberculosis was found incidentally after the subtotal gastrectomy performed under the impression of stomach cancer. There was an ill-defined ulcerative lesion at the lesser curvature. Microscopically, poorly differentiated adenocarcinoma extended to the serosa and typical tuberculous granulomas were found in the lesion of stomach and regional lymph nodes. Acid-fast bacilli were demonstrated by Ziehl-Neelsen stain in the granuloms of the regional lymph nodes, and a case of gastric carcinoma is presented here and briefly reviewed with the literature.

A clinical review was made on 48 cases with cor pulmonale who were admitted to medical department, National Medical Center, between 1973 and 1982, and the results were as follows : 1) Teh age of subjects ranged from 26 to 88, and their mean was 51. male to female ratio was 1.6:1 and majority of them were in their 6th and 7th decade. 2) COPD was the most common cause of cor pulmonale but pulmonary tuberculosis had also a considerable portion. Less commonly it was caused by chest deformity which was mainly from spine tuberculosis and kyphoscoliosis. 3) Almost all patients were admitted with over heart failure. 4) Laboratory features showed indirect evidence of heart failure and pulmonary hypertension in chest X-ray films, RVH patterns in EKG and hypoxia and hypertcapnea with metabolic compensation in arterial gas analysis. 5) The case fatality rate was one-forth and that from kyphoscoliosis was especially high(80%).

In parentage testing DNA profiles are used to link the alleged father with paternity by matching their patterns. The probative value of a match is often calculated by multiplying together the estimated frequencies with which each particular VNTR or STR pattern occurs in a reference population. When this calculating method applies to the motherless case of paternity disputes, a calculation must usually be based on types determined for the child and the alleged father. In such case, the first consideration is to exclude a man from paternity of a child when the man did not have the child's paternal allele at some loci, or if the paternal allele cannot be determined, when the man had neither of the child s alleles. The second is to evaluate the DNA evidence when a man is not excluded by the paternal allele. This work is to provide theories of paternity analysis with three approach methods for the motherless case, and to evaluate their efficiency compared to the trio case when the man tested is not excluded. Consequently, the motherless case offers lower probability exclusion and questionable cumulative paternity index than those of the trio case as being typed with 14 STR loci(CSF1PO, TH01, TPDX, vWA, D5S818, D13S317, D7S820, D16S539, FGA, D21S11, FES/FPS, F13A1, D18S80, D17S5). Since the motherless case in paternity disputes is less efficient for paternity exclusion of the child, the use of genetic maker systems with the higher value of mean exclusion chance(MEC) and exact levels of the relative probability of paternity must be of importance considered in the analysis of such deficiency cases.

The HUMACTBP2 locus was investigated to collect population genetic data in the Korean population and to evaluate the applicability for the forensic field. An Automatic fluorescent-based sequencer (377 automatic DNA sequencer, ABI) was used to detect amplified fragments of the HUMACTBP2 locus electrophoresed on 4% denaturing polyacrylamide sequencing gels. ACTBP2 allelic ladder consisting of different sizes of 18 alleles was constructed and employed as an internal size standard in combination with a GS-350 size standard for precision of allele-band sizing. By utilizing different fluorescent dyes, both the allelic ladders and samples were able to be analyzed in the same lane by 99% orecision of allele-band sizing. Among the Korean population (n=224), 26 alleles in the range of 239-313 bp are determined. allele No. 6 is found 45 times (0.100) which is mostly frequent, and the rest of allele is distributed with their relative frequency of 0.002-0.100. The comparison between observed and expected numbers of homozygous and heterozygous individuals confirms that ACTBP2 locus is in the state of Hardy-Weinberg equilibrium among the Korean population. The heterozygosity is 0.9389+/-0.0034(93.89%), and the power of discrimination(PD) and power of exclusion(PEX) are calculated to be 0.991(99.1%)and 0.890(89.0%), respectively, showing the high informativeness for individual identification. Thus, these results mean that the HUMACTBP2 locus can effectively be used for the forensic application.

Inflammatory mediators, such as oxidants, TNF-alpha, and IL-6, play a major role in the systemic response to bum injury It has been known that a continuing inflammatory response cause a sepsis and subsequent multiple organ failure. Recent studies have shown that burn patients receiving recombinant human growth hormone(rhGH) therapy have an improvement of the general condition, but the mechanism by which rhGH exerts its effects has not been clearly understood. The aim of this study was to evaluate the effect of rhGH on the early bum injury. Female Sprague-Dawley rats were divided into four groups : control group, bum group, burn plus rhGH treated group, and rhGH only treated group. Animals were killed at 30min., 3, 6, 24, and 48 hours after treatment. Histology and biochemical changes including malondialdehyde(MDA) content, tissue reduced glutathione(GSH) and catalase activity in the lung and liver, and plasma TNF-alpha and IL-6 levels were examined. Lung histology in the bum plus rhGH treated group showed decreased inflammtory response such as neutrophil and lymphocyte infiltrations, interstitial thickening, and edema compared with the bum group. Liver histology in the bum group revealed mild neutrophil and lymphocyte infiltrations, vacuolization .of hepatocytes, disrupted lobular structures, and dilated sinusoids. But liver histology of the bum plus rhGH was similar to control group. Lung and liver MDA in the burn plus rhGH and rhGH only treated groups were decreased with time compared with the burn group. Lung and liver GSH and catalase activities in the bum plus rhGH and GH only treated groups remained significantly increased compared with the bum group for the 48-hours period. Plasma TNF-alpha levels in the bum group remained elevated for the 48-hours period compared with the bum plus rhGH and rhGH only treated groups. Plasma IL-6 levels in the burn group were significantly increased only at first compared with the bum plus rhGH and rhGH only treated groups. These results suggested that rhGH showed inhibitory effects on the inflammatory cell infiltration and lipid peroxidation in the lung and liver after bum injury. Increased GSH levels and catalase activities seemed to be associated with the antioxidant effect of rhGH. But the inhibitory effect of rhGH on plasma TNF- and R-6 levels was not clearly demonstrated.

The effect of dexamethasone of the maturation of the fetal lungs of rats with streptozotocin-induced diabetes was studied morphologically and biochemically. By light and electron microscopy there was little difference in fetal pulmonary maturation between the untreated control group and the untreated diabetic group, but when both groups were treated with dexamethasone the fetuses showed accelerated pulmonary maturation, approximately one day earlier with an increase of air spaces per unit area and an earlier appearance of type II pneumocytes. The number of osmiophilic inclusion bodies per alveolus and per type II pneumocyte, and the lecithin/sphingomyelin ratio in amniotic fluid increased markedly and they were statistically significant in both groups injected with dexamethasone, but were decreased in the untreated diabetic group, though only the L/S ratio of the animals of the 19th day gestation was statistically significant. Phosphatidylglycerol was present in the amniotic fluid of the groups injected with dexamethasone one day earlier than the untreated control and the untreated diabetic groups. However, the intensity of phosphatidylglycerol tended to be lower in the untreated diabetic group. It is concluded that the prenatal administration of dexamethasone to the diabetic pregnant rats will accelerate fetal pulmonary maturation morphologically and promote the synthesis of surfactant biochemically.

Chemically induced epiderml carcinogenesis is usually divided into two stages, the initiation and promotion. The initiation involves conversion of some epidermal cells into latent neoplastic cells and the promotion is proliferation of the transformed cells. As immunosurveillence is thought to be a host defense against tumors, Langerhans cells, being essential in initiation of local cutaneous immunologic reaction, is suggested to be important in the carcingenesis of the epidermis. This study is attempted to investigate the epidermal proliferative changes in mice induced by application of 12-0-tetradecanoy1-phorbol-13-acetate(TPA) on the skin initiated with 7, 12-dimethylbenzanthracene(DMBA) and its relationship with Langerhans cell. Ninty five male inbred BALB/c mice weighing 20~25 g were divided into five groups; the 33 week-group, the 21 week-group, the 12 week-group and the 4 week-group according to the duration of carcinogen application, and the control group. The carcingen was applied with a brush on the dorsal skin of mice after depilation. Ten days after application of 800 nmole DMBA in 0.4 cc acetone, 20 nmole TPA in 0.4 cc acetone was applied twice per week and the control group was applied with the same amount of acetone for 4 weeks. Animals were sacrificed 3 days after the last application of TPA. One hour before sacrifice, bromodeoxyuridine(BrdU) (1 mg/g) was injected via the tail artert for BrdU stain of S phase cells. A strip of dorsal skin was used for hematoxylineosin stain, immunohistochemical stain for BrdU and la antigen of Langerhans cell, and flow cytometry. The results are as follows: 1. Cellular proliferation, hyperkeratosis and dysplasia of the epidermis were increased in relation to duration of carcingen application. Papillomas were developed 12 weeks after application of the carcingen. 2. BrdU labelling and proliferative indices of the 20 weeks' application group were significantly higher than those of the 12 weeks' application group. The number of Langerhans cell was decreased markedly ater 4 week' application of the carcinogen. 3. All epiedrmal lesions including a case of squamous cell carcinoma were diploidy in flow cytometry. It is thought that disturbance of immunosurveillence, caused by depletion of Langerhans cell, may permit proliferation of epidermal cells. Although abnormal quantitative change of nuclear DNA has not occurred even when the epidermal proliferative activity and dysplastic change were increased markedly, it is thought that the occurrence of structural change of chromosome is remained to be clarified.

We have experienced a rare case of leukemic lesion(chloroma) in the lower spinal canal which was confirmed by the surgery and histologic examination of the tumor. A farmer, aged 39, was admitted to the Department of Neurosurgery, St. Paul Hospital in December 1974 with chief complaints of low back pain with radiating pain in the right lower extremity and voiding difficulty for one month. On admission, neurologically, the patient exhibited weakness of the right anterior tibialis, extensor hallucis longus and peroneus longus and brevis muscles and sensory involvement of the right third, fourth and fifth sacral dermatomes. He was disclosed the positive signs of the Naffziger's and Lasegue's and severe tenderness on the spinous process of the fifth lumbar and first sacral vertebrae. Lumbar myelogram demonstrated a total block at lower level of the fifth lumbar vertebra and a filling defect of the right fifth lumbar root area. Through the laminectomy of fourth lumbar to first sacral lamina, an extradural greenish soft mass located at the ventral aspect of the right fifth lumbar to upper sacral roots, and the mass was removed. The biopsy specimen disclosed chloroma with leukemic infiltration of the meninges.
