This experiment was performed to study the influence of hypertonic saline on the production of the secretory granules by the cellular organelles of the jejunal Paneth cells of the rabbit fed on the 3 % hypertonic saline. The jejunal mucosae of the experimental rabbits were removed partially in the upper one third of the jejunum and fixed in 2.0% glutaraldehyde for 2 hours, followed by 1% osmium tetroxide fixative for 2 hours. Then they were embedded in epon mixture, cut with ultramicrotome and done uranyl acetate-lead citrate double stain, and observed with JEM100 CX Ⅱ electron microscope. Observed results were as follows: 1. The number of secretory granules of a higher electron density was gradually increased as a whole in the course of time after feeding on the hypertonic saline. 2. After feeding on the hypertonic saline, secretory granules of various sizes with a higher electron density mostly occupied the supranuclear region of Paneth cells, but a few secretory granules of various sizes with low electron density were observed. 3. After feeding on the hypertonic saline, the Goigi complex, the mitochondria and the rough surfaced endoplasmic reticula were gradually figured, especially the cisternae of the rough surfaced endoplasmic reticula displayed polyhedral shapes. 4. Considering the above findings, following the feeding on the hypertonic saline, the function of the jejunal Paneth cells was influenced and secretory granules of various sizes with a higher electron density were more abundant as compared with those of a lower electron density. From the above results, it was considered that the Golgi complex, the mitochondria and especially the rough surfaced endoplasmic reticula were activated to maintain homeostasis. As a result of that, the production and concentration of secretory granules were prominently observed.

Yongdam multipurpose dam is under construction to divert a part of Geum riverflow to Mankyung watershed and to supply the domestic water to the Chunju region and produce the hydro-electricity. Generally, construction of dam by the method of inter-regional water transfer affects the quantity and quality of water in the down streams and reservoirs. The impact of operation plan of Yongdam dam on the quantity and quality of water in the Geum river and Daechung dam was investigated. It was recommended that the discharge of water transfer from one watershed to another should be minimized as much as possible.
개 이자의 Somatostatin 양성세포의 발달에 관한 면역조직화학적 연구

Cells immnunoreactive for somatostatin(SOM) and glucagon(GLU) were investigated in postnatal day 0, 7, 14, 28, 90, 180 and adult canine pancreas using light microscopic immunohistochemistry. Pancreatic SOM-immunoreactive cells were found in pancreatic acini, pancreatic duct, and pancreatic islet gradually. Pancreatic SOM-immunoreactive cells were more located in pancreatic parenchyme than pancreatic islet throughout pancreas by postnatal day 28. But there was change by the postnatal 3 months : pancreatic SOM-immunoreactive cells were more located in pancreatic islet than acini and duct. It is suggested that the number of the SOM-immunoreactive cells may not increase with age apparently. A small number of SOM-immunoreactive cells that showed GLU-immunoreactivity were also observed in canine pancreatic islet. The physiologic consequences of these changes remain to be determined. These results sugegest that SOM in the developing pancreas may relate to the secretion of pancreatic hormones.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.
CASE REPORT : A Case of Localized Amyloid Light-Chain Amyloidosis in the Small Intestine

Amyloidosis is characterized by the abnormal deposition of extracellular amyloid fibrils. Cases involving amyloid light-chain amyloidosis in the small intestine have been reported infrequently in Korea. Here, we report a case of localized light chain protein amyloidosis in the small intestine. Esophagogastroduodenoscopy, push enteroscopy, and capsule endoscopy revealed submucosal tumor-like lesions, multiple shallow ulcers, and several erosions in the distal duodenum and jejunum. An endoscopic biopsy established the diagnosis of amyloidosis. In through an immunohistochemical analysis, the presence of lambda light chain protein was detected. The patient had no evidence of an underlying clonal plasma cell disorder or additional organ involvement. Therefore, we concluded that the patient had localized amyloidosis of the small intestine.
