Recurrent epistaxis is not one of rare symptoms in children, the well-known causes of which are anatomical abnormalities of nasal cavity and systemic bleeding tendency. but, in the majority of cases of recurrent epistaxis, it is usually very difficult to find out their underlying causes, so that the treatment is only symptomatic control of nasal bleeding whenever epistaxis occurs, but it usually is impossible to manage against their underlying causes as a specific therapy. The authors considered the breakdown or weakness of vascular integrity of nasal capillary vessel wall as an important factor of recurrent epistaxis, and vitamin C, which has an important role for the synthesis of collagen fiber, could influence to the vascular integrity of nasal capillary vessels. To elucidate the relation between recurrent epistaxis and the status of vitamin C in the tissue of the patients, the authors performed urinary vitamin C loading test measuring urinary excretion of vitamin C with high-performance liquid chromatography by Sirota et al in 19 cases of control group and 32 cases of patients with recurrent epistaxis, whose underlying diseases were not identified. And also the authors administered 1.0 gm/day of vitamin C orally for the treatment of recurrent epistaxis and follow-up was done over 1 year from the beginning of treatment to evaluate the treatment response. The results were as follows: 1) The hemoglobin level was significantly decreased in patient group compared with that of control group (12.4+/-0.8 vs 9.0+/-3.2 gm/dl). 2) The results of urine loading test of vitamin C, expressed as the percent excreted ratio, revealed significantly decreased in the patient group compared to that of the control group (9.1+/-6.1% vs 13.6+/-7.9%). 3) After treatment with 1.0 gm/day of vitamin C orally, follow-up was possible in 23 cases of total 32 patients. Of the 23 patients, "excellent" therapeutic response were in 16 cases (69.6%), "good" response in 5 cases (21.7%), and "no response" only in 2 cases (8.7%). The overall treatment response were in 21 cases (91.3%). In conclusion, it seems that majority of the patients with idiopathic recurrent epistaxis in the deficient state tissue vitamin C so that administration of vitamin C will be one of the effective therapy.

Although the ultrasonography has been regarded as a main procedure in the diagnosis of gallbladder diseases, no many papers concerning the ultrasonographic findings of gallbladder empyema appeared in the literature. Twenty-four cases of surgically proven gallbladder empyema were studied by ultrasonography in our hospital during last 15 months. The results were as follows; 1. The size of gallbladder was enlarged in 18 cases. 2. The thicknessof gallbladder wall was more than 3mm in 16 cases. 3. The echogenicity of gallbladder wall was diminished in all cases. the inner margin of gallblaldder wall was also ill-defined in all cases. These findings are considered to be important in the diagnosis of gallbladder empyema. 4. The internal echogenicity of gallbladder (diffuse or localized) was positive in 16 cases and negative in the remainders. The echo genility was thought to beproportional to the amount of pus in gallbladder. 5. The 7 cases presented periocholecystic sonolucent area hadperforation of gallbladder and pericholecystic abscess. 6. Gallstone was found in 17 cases.

Cryptosporidium parvum oocysts were isolated from a child suffering from acute gastroenteritis and successfully passaged in a calf and mice (designated hereafter SNU-H1) in the Republic of Korea; its molecular genotype has been analyzed. The GAG microsatellite region was amplified by a polymerase chain reaction (PCR), with a 238 base pair product, which is commonly displayed in C. parvum. The isolate was shown to be a mixture of the genotypes 1 (anthroponotic) and 2 (zoonotic). To study its infectivity in animals, 2 calves and 3 strains of mice were infected with the SNU-H1; in these animals, the propagation of both genotypes was successful. In immunosuppressed (ImSP) BALB/c and C57BL/6 mice the number of oocysts decreased after day 10 post-infection (PI) ; but in ImSP ICR mice, they remained constant until day 27 PI. The results show that both the C. parvum genotypes 1 and 2 can be propagated in calves and ImSP mice.
