The results of 16 cases of herpes simplex keratitis treated by cryogenic method are presented. The cryoapplicators(2 mm and 4 mm in diameter of tip) were applied on the lesions 5-7 seconds and antibiotics and atropine solutions were instilled. No complication by cryogenic treatment was happened. The new vessels in the cornea were faded after cryocautery for the treatment of herpes simplex keratitis.

The use of hormonal stimulation in human in vitro fertilization and embryo transfer (IVF-ET) leads to increased production of embryos for ET. So to avoid high pregnancies and to allow conception in future, unstimulated cycles, cryopreservation of spare embryos is desirable. One of the improvement of cryopreservation methods is vitrification. We cryopreserved mouse day 3 embryos by vitrification using the three different vitrification solution (EFS40, VSll and VS3a). EFS40 solution is consisted of 40% (v/v) ethylene glycol, Ficol170 30% (w/v) and 0.5M sucrose and VSll is 6.0M ethylene glycol and 1.8M glycerol. And VS3a is 6.5M glycerol and 6% (w/v) BSA (bovine serum albumin). First we tested the toxicity of three vitrification solution by exposure to these solution during 3 min. After washing by thawing solution, the survival rates of each groups are 95.5%, 90.9% and 84.4% (EFS40, VS11 and VS3a). High percentages of them developed to expanded blastocyst and hatching embryos in culture 48hrs 94.2%, 97.7%, 100% and 97.4% (no treatment group, EFS40, VS11 and VS3a). So there is no significant differences among the each group. Second, after thawing of vitirfied embryos, the survival rates of each groups are 96.8% (slow freeze), 94.1% (EFS40), 85.5% (VS11) and 80.0% (VS3a, P vs. no freeze or EFS40 is 0.01). Vitrified embryos exhibited a high rate of development in vitro after 48hrs culture. The percentages of each group to blastocyst and hatching embryos are 88.7% (no freeze), 91.8% (slow freeze), 93.4% (EFS40), 87.7% (VS11) and 73.0% (VS3a, P vs. other group is 0.01). The results suggest that there is no significant differences in exposure of various vitrification solution and day 3 mouse embryos can be vitrified in solution EFS40 and VS11 by simple procedure.

This investigation was aimed to study the effect of contrast media on the cardiovascular system. So in thisstudy, pithed rats were used whether alteration in cardiovascular system by contrast media were controlledcentrally. Furthermore, several hypertonic solutions were also used to clarify the effect of contrast media. Theresults are as follows: 1. Intravenous injection of contrast media in rats(2.5m/kg) caused hypotension andbradycardia. The effects were neither blocked by pretreatment of atropine nor pyribenzamine+atropine. 2. NaCl4.7%, dextrose 24.8%, urea 9.0% and glycerol 10.1%(v/v) which were equiosmolar with contrast media, causedhypotension, but did not affect the heart rate. 3. In pithed rats, intravenous injection of Angiografin increasedblood pressure in a dose-dependant manner, and caused decrease in heart rate compared with those of control rats. 4. In pithed rats, bradycardia by intravascular injection with Angiografin was partialy blocked by atropine. 5.Metrizamide of which iodine content was adjusted to 280 mg/ml caused increased in blood pressure when was injectedintravenously in pithed rats with little effect on heart rate. 6. When perfused with contrast media in rathindlimb at 15ml/kg speed both perfusion pressure and flow effluent incereased, simultaneously. These resultssuggest that hypotension might be caused by the central effect due to hyperosmolarity of contrast media andbrachycardia caused by both parasympathetic stimulation and direct inhibitory action on the cardiac conductivesystem.

Hemangiopericycic maningioma is clinically and pathologically similar to peripheral Hemangiopericytoma and now tends to be terned as hemangiopericytoma of central nervous system. The authors studied 3 cases of hemangiopericytic meningioma obtained from 3 patients, 1 case of meningotheliomatous meningioma, angioblastic meningioma and transitional meningioma, and 2 cases of peripheral hemangiopericytoma, which had operated from November 1988 to May 1989 at the department of neurosurgery, Pusan Inje University Hospital. The authors analysed and compared the immunohistochemical finding and light microscopic apearance. The results obtained were summarized as follows; 1) Classic maningioma (meningotheliomatous meningioma, transitional meningioma and angioblastic meningioma) shows reactivity to both EMA and vimentin. 2) Hemangiopercicytic meningioma and peripheral hemangiopericytoma are reactive only to vimentin, so the two tumors are suggested as same type of tumor. 3) One of 3 cases of hemangiopericytic meningioma shows whorling and interlacing bundles of spindle cells, the peculiar light microscopic features of transitional meningioma, suggesting transitional or mixed form of hemangiopericytic meningioma and transitional meningioma.

This survey was conducted in February 24, 1999, in order to investigate the nutritional knowledge and dietary attitude of the school dietitians working in Kyungnam area. Subjects consisted of 305 school dietitians of which 163 married and 141 unmarried. The results obtained are summarized as follows : The average nutritional knowledge score was 10.50 out of possible 15 points, and dietary attitude score was 69.36 out of 100 points. Most of the subjects belonged to "Fair" group in terms of nutritional knowledge and dietary attitude level. Married dietitians scored significantly higher on dietary attitudes than unmarried dietitians (p<0.05). The correlation between nutritional knowledge score and dietary attitude score was not statistically significant(r=0.107)

Sirenomelia is a severe form of caudal regression syndrome that results in a fusion of the lower extremities, which is not compatible with life. A various spectrum of anomalies affecting primarily the musculoskeletal, genitourinary and gastrointestinal systems also can occur. This rare malformation has a reported incidence rate of approximately 1 in 60,000 births, with a range of 1 to 1 percent of all malformed infants. We experienced a sirenomelic case with combined anomalies of genitourinary, cardiovascular and gastrointestinal systems. Maternal obstetric history revealed oligohydramnios and intrauterine fetal growth retardation, and the baby was spontaneously delivered at 37 weeks of gestational age, but died I hour after birth.

Acute infectious myocarditis in children can be caused by many pathogens, including bacteria, viruses, fungi and protozoa. Patients may be asymptomatic or may have 'flu-like symptoms' to life-theratening arrhythmias or sudden death. We herein report a case of acute myocarditis complicated by complets and permanent AV block, associated with Salmonella group B gastroenteritis in a previously healthy 5-year-old boy. Presenting symptoms were dyspnea, cyanosis, vomiting, and diarrhea. Electrocardiography on admission showed very slow ventricular escape rhythm at 37 beats/minute. He was treated with antibiotics, inotropic agents, ventilatory support, and transvenous temporary pacemaker. Ten days later, permanent dual chamber pacemaker was implanted. All three consecutive stool cultures done after admission grew Salmonella group B. His ventricular function recovered rapidly and completely and he became fully active 2 months after the onset. However, his conduction system was totally destroyed and at last follw up evaluation 2 years after the onset, he is still totally dependent on the pacemaker without any escape rhythm.
