Jejunal and ileal atresias are the most common cause of congenital intestinal obstruction and accounts for about 1/3 of all cases of intestinal obstruction in newborns. Despite the relative frequency of this anomaly, its survival rate was less than 10% up to 1950, more recently the survival rate has risen rapidly to 90% with the introduction of modern surgical techniques and the use of total parenteral nutrition. In 1969 Thomas described a tapering jejunoplasty to manage the discrepancy in the size of the proximal dilated lumen & contracted distal lumen, and to preserve absorptive surface when the dilated jejunum involved a long length, and Grosfeld et al.(1979) facilitated this method by using GIA staplers. Author have also used GIA stapler to resect the antimesenteric portion of the dilated proximal bowel in 8 cases of jejunoileal atresias with good results. The following results were obtained ; 1. There we 3 jejunal atresias & 5 ileal atresias, and male to female sex ratio was 5 : 3. 2. The type of atresia was as follows ; type IIIa was 3 cases, type IIIb was 4 cases, type IIIb+IV was 1 case. 3. In non-complication cases(5 cases), the mean hospital day was 16 days, and oral feeding was feasible from 6.2 days after operation. 4. The complications(anastomotic leakage, pneumonia) were frequently occurred in type IIIb cases and in low birth weight cases(75%). 5. Mortality rate was 25% including DAMA(discharge against medical advice) discharge case.

A diagnosis of iodine-deficient goiter was confirmed in newborn piglets that were born hairless edematous, and with markedly enlarged thyroid gland. Clinically, most of the piglets were born dead, extreme weakness or dying within a few hours of birth. Gestation periods were prolonged for 3-7 days. Histopathologically, hair follicles were scarce and reduced in size, contained slender hairs, and revealed a shallow penetration into the hypodermis that showed severe diffuse edema. Thyroid glands had severely hyperplastic follicles and poorly staining colloid. The follicles were irregular in size and shape depending on varying amounts of lightly eosinophilic and granular colloid in the lumen. The iodine content of the diet fed to the sows and plasma total thyroxine and triiodothyronine concentration of sows were very low. This is a first report for iodine-deficient goiter in newborn piglets in Korea.

Tsaiya ducks and Leghorn hens are the two major laying birds raised in Taiwan. They are all excellent egg layers. Tsaiya ducks are small in body size (1.3 kg) with bigger egg weight (65 g) and stronger eggshell breaking strength than eggs from hens. The eggshell consists mainly of calcium carbonate, hence calcium plays an important role in the eggshell formation. Magnesium is also present in eggshell in small amounts, which may have effect on maintaining eggshell quality. In comparison studies, it was shown that the duck eggshells contained higher calcium and lower magnesium content than chicken eggshells. The eggshell magnesium content was not affected by the dietary magnesium levels (690-2380 ppm) in ducks, but in hens, it increased linearly with dietary magnesium levels. The palisade layer ($5000{\times}$) of the eggshell was found to have a compact form for ducks while there are many hallow vesicles in chicken eggshells. The eggshell magnesium deposition model is different for ducks and hens with ducks having a one-peak and hens having a two-peak model. The calcium deposition model is similar for both birds. Both the carbonic anhydrase specific activity and total activity in the shell gland mucosa of ducks are higher than those in hens. Ducks retain higher magnesium and lower calcium in the shell gland mucosa and secret less magnesium and more calcium into the shell gland lumen for eggshell deposition. The ATPase specific activity is maintained fairly constant during the eggshell forming stage, indicating continuous calcium transport into the shell gland lumen for eggshell formation. The magnesium content in duck eggshells is much lower than that in hens indicating that the magnesium content in the eggshell may have an effect on eggshell quality.

Infection effect of $Nosema$ $bombyics$ on the midgut of silkworm $Bombyx$ $mori$ and subsequent appearance of spores and the performance of larvae was studied. Autopsy of larvae showed white pustules on the surface of midgut at 5 days of post infection (pi). At later stage, important organs like midgut, silk gland and gonads reduced in size and all these organs showed white pustules. Light microscope observation of pustules revealed enormous spores. Spore multiplication was at a faster rate in young larvae. Infection of the adult larvae resulted in pebrinized pupa and moths. Larval weight, cocoon weight and cocoon shell ratio reduced as the post infection period increased. Transverse sections of midgut showed $N.$ $bombycis$ infection limited to a few columnar cells at 3-5 days of pi. At 7 days pi, cell volume increased, cells were swollen and elongated. Heavily infected cells looked like sacks filled with parasite and the apical region of certain cells were bulging into the gut lumen. Later at 8-9 days of pi, spores or its developing stages leaked into the lumen either freely or enclosed within the globules of host cytoplasm. Besides columnar cells, development of $N.$ $bombycis$ was observed in the regenerative cells and rarely in goblet cells. Development of $N.$ $bombycis$ was also observed in both longitudinal and circular muscles at the late pi period. The histopathological changes, deformities and spore production time in the host were all influenced by the spore dosage and age of the host.

Ultrasonographic study was undertaken to establish the echogenecity and size of reproductive organs of 18 cycling buffaloes of different parities and compared with the sizes measured by palpation per rectum at estrus (day 0), met estrus (day 2), mid diestrus (day 10) and late diestrus (day 16). The overall mean size of cervix, uterine body, right horn, left horn, right ovary and left ovary measured by palpation per rectum were 2.70$\pm$0.43, 2.36$\pm$0.36, 2.17$\pm$0.37, 2.12$\pm$0.38, 2.63$\pm$0.41 and 2.72$\pm$0.37 cm, respectively. The corresponding ultrasonographic observations were 2.10$\pm$0.40, 1.85$\pm$0.30, 1.73$\pm$0.36, 1.64$\pm$0.37, 2.16$\pm$0.36 and 2.29$\pm$0.38 cm respectively. Variations in the size of genitalia due to stages of estrous cycle were non-significant. The size of genitalia measured by palpation per rectum was significantly higher (p<0.05) than by ultrasonography. However, there was linear positive correlation (r=+0.87) in the measurements by the two techniques. The ultrasonographic characteristics of tubular genitalia revealed different echogenic gray shades around the nonechogenic (black) central area of lumen depending upon the stage of cycle. The ovarian stroma appeared as hyperechoic (white) area with nonechogenic (black) follicle. The corpus luteum (CL) exhibited different echogenic texture viz. grayish black, grayish granular and grayish white at met estrus, mid diestrus and late diestrus, respectively. Therefore, ltrasonography can be effectively employed to record the exact size and echotexture of the buffalo genitalia during different stages of estrous cycle.

Wastewoods (logging residues) generated in Korea were used to make lignocellulosic fillers for papermaking. Lignocellulosic fillers could play great roles to increase retention efficiency and thus decrease turbidity of white water in papermaking process. In addition, lignocellulosic fillers could be used to improve physical properties of paper through their high affinity to cellulosic fibers, leading to the less use of chemical additives like retention aids. Wastewoods including Pinus densiflora and Quercus variabilis were chemically and mechanically treated for making fine particles passing through 100 mesh wire. The newly generated fillers showed larger particle size distribution than ground calcium carbonates but similar distribution to talc. In particular, pretreatment by hot water was more effective to generate smaller particle size than by alkali treatment. Lignocellulosic particles mixed with ground calcium carbonates under intense hybridizing condition greatly contributed to surface coverage of organic fillers in addition to filling to lumen and pits.

The Sialolithiasis is one of the most common disease that is found in the submandibular gland and they can be usually observed in the extra glandular area. As the lumen of Wharton's duct is larger and more expandable than that of Stensen's duct, the symptom of them is initially painless. As increasing their size, the sign and symptom are pain and sudden enlargement of gland. It can be observed with clinical exam and the scintigraphy. After removal of sialoliths, the majority of them can get the recovery of function. Our department performed the transoral sialolithotomy and the extraoral sialoadenectomy for three patients of sialolithiasis and all of them showed no complication after operation.

Four dead wild racoons found in Chonnam province were examined parasitologically, pathologically and bacteriologically. Using standard flotation technique with feces many number of ancylostoma eggs which were oval in shape and $60-70{\times}35-45 {\mu}m$ in size were detected. Grossly, severe anemia, multiple congestion and consolidation of lung and catarrhal exudate in small intestine were observed. One of racoons had multifocal white to yellow nodules in the liver. Histopathologically, ancylostoma larvas were found in intestinal lumen. Some of them penetrated and attached to intestinal mucosa. Lungs revealed multiple severe fibrinopurulent pneumonia in which bacterial colonies were scattered. Liver had multiple microabscesses containing peripheral bacterial colony. By Gram stain using paraffin sections of liver and lung, bacterial colony was Gram negative. Isolated bacteria from lung and liver was Gram negative rod. This bacteria was identical with Escherichia coli by biochemical tests. From these results, ancylostomiasis caused severe problems in Korean wild racoons. This is the first report about ancylostomiasis in wild racoons in Korea.

Balantidiasis is an infectious disease worldwide which is produced by a protozoan Balantidium coli. This single-celled organism is characterized by their large size ranging from 50 $\mu\textrm{m}$ to more than 500 $\mu\textrm{m}$ [1] which indicated by the presence of cilia on its cell surface. The parasite occurs in the lumen of cecum and colon of swine, humans and nonhuman primates as commensal, but can turn opportunist and invade injury tissues by other diseases [2]. It is difficult to diagnose the disease clinically since they are asymptomatic [3]; and can be complicated with other disease or parasitism. Here we report the incidental findings of Balantidiasis in the lymphatic ducts of gastric lymph node of Barbary sheep (Ammotragus lervia). (omitted)

Gallbladder (GB) polyp is a mucosal projection into the GB lumen. With increasing health awareness, GB polyps are frequently found using ultrasonography during health screening. The prevalence of GB polyps ranges between 1.3% and 9.5%. Most patients are asymptomatic and have benign characteristics. Of the nonneoplastic polyps, cholesterol polyps are most common, accounting for 60%-70% of lesions. However, a few polyps have malignant potential. Currently, the guidelines recommend laparoscopic cholecystectomy for polyps larger than 1 cm in diameter due to their malignant potential. The treatment algorithm can be influenced by the size, shape, and numbers of polyps, old age (>50 years), the presence of primary sclerosing cholangitis, and gallstones. This review summarizes the commonly recognized concepts on GB polyps from diagnosis to an algorithm of treatment.
