This study was conducted to investigate the vibrio flora in sand shrimp, Crangon affinis, which were collected in the estuarine area, Dadaepo near Nakdong River in Korea from in June 1996 to in May 1997. Crangon affinis is very important role in food chain in nature because of food for many seabirds and fishes. Six species of vibrios (Vibrio alginolyticus, V. parahaemolyticus, Listonella damsela (V. damsela), V. harveyi, V. splendidus biotype I, V. splendidus biotype II, and V. natriegens, an unrecorded species in Korea) were isolated from the intestine of shrimps and characterized by the biochemical tests.

Proximal femoral focal deficiency (PFFD) in early infancy is characteristic by quite shortening of the tight segment, flexed, abducted and externally rotated position In assciation with a stable hip which Is freely mobile. Authors experienced a case with the congenital deficiency of the femoral head. The case showed the normal femoral segment and no any other bony anomalies which cannot be Included in Aitkens or Amstutz's classification.

BACKGROUND: Topical irritants disrupt the cutaneous permeability barrier through the removal of stratum comeum lipids. This perturbation of barrier integrity stimulates a variety of homeostatic repair responses that ultimately result in the normalization of bamer function. Object To measure the effect of desoxymethasone ointment, vaseline and hydrobase on the barrier recovery of benzalkonium chloride (BKC) imtated skin. MATERIALS AND METHODS: The left flank skin of 2-3 monthold hairless mice was treated with BKC and then desoxymethasone ointment, vaseline and hydrobase were applied. Transepidermal water loss (TEWL) was checked after 0, 3, 6, 9, 12, 15, 18, 21 and 24 hours. Electron microscopic examination was performed after 3 and 24 hours after desoxymethasone, vaseline and hydrobase had been applied. RESULTS: The recovery of TEWL was most prominantly observed in the desoxymethasone ointment treated group followed by vaseline and hydrobase. Electron microscopic examination using ruthenium tetroxide fixation revealed that secretion and numbers of lamellar bodies and complete formatice of lipid bilayers were most prominent at desoxymethasone ointment and vaseline treated group. CONCLUSION: Desoxymethasone ointment, vaseline and hydrobase can be good agents in improving bamer recovery after exposure to irritant material.

OBJECTIVE: Multiple birth implicates the important health and social problems such as preterm birth, low birth weight, high perinatal mortality, and increased medical cost. This study was performed to investigate the multiple birth rate in Korea using the birth certificate data. METHODS: Retrospective review and analysis of data from Korean birth certificate in 1996. RESULTS: Multiple birth rate was 1.4% of total births(683,043 cases). Mean birth weight was 3.29+/-0.47kg for singleton birth and 2.57+/-0.58kg for multiple birth. Mean gestational age was 39.56+/-1.32 weeks for singleton birth and 37.47+/-2.41 weeks for multiple birth. Rate of low birth weight (< 2.5kg) was 14 times higher for multiple birth compared with that of singleton birth, and rate of preterm birth(< 37 weeks) was 10 times higher. Multiple logistic regression analysis was performed to examine the relationship between multiple birth and selected variables including maternal age, job and birth order. As the odds ratio(OR) was 2.47(95% CI: 2.34 - 2.59, p<0.001) for the second birth, and 5.31(95% CI: 4.99 - 5.65, p<0.001) for the third and over birth compared with the first birth, there was a significant correlation between multiple birth and birth order. CONCLUSIONS: Based on the birth certificate data in 1996, the incidence of twin and higher order multiple birth was 1.7%, and a significant correlation between multiple birth and birth order was revealed. Further studies are necessary to elucidate the etiology and prognosis of multiple birth and the developmental problems from birth to adolescence.

Pruritic folliculitis of pregnancy of pregnancy is a specific dermatoses of pregnancy which is characterized by erythematous follicular papules and pustules between the fourth and ninth month of pregnancy. It has usually resolved by 4 weeks of postpartum and has no adverse implications for mother and baby. We report a case of pruritic folliculitis of pregnancy in a 24-year-old primigravida woman who had had monomorphic erythematous follicular papules and pustules on her anterior chest wall and back. Histopathological findings of erythematous papules showed acute folliculitis and perifolliculitis. The skin lesions improved rapidly with 2 weeks of delivery without treatment.

Canalith repositioning maneuver is effective to treat benign paroxysmal positional vertigo(BPPV). This case showed complicated form of the BPPV such as changes of canalolithiasis to cupulolithiasis, involvement of one canal to two canals and from unilateral to bilateral involvement during the reposition maneuver. This patient was diagnosed as left lateral canalolithiasis at first. After left barbecue maneuver, the type was changed to the right posterior cupulolithiasis. Semont maneuver was performed and then the type of BPPV was changed to combined type with right posterior canalolithiasis and left lateral canalolithiasis. We performed left barbecue maneuver and right Epley maneuver. Then the type of BPPV was changed to left lateral cupulolithiasis. After Brandt-Daroff maneuver and left barbecue maneuver, nystagmus and dizziness disappeared finally.
