This study aimed to compare practically design optimization on cooling and heating hydronic system by application of unique and innovative flow control valve. Total commissioning kit of PICV shows good advantage of component dealing and maintenance with assembling PICV, drain kit, air vent and flow measuring port by one kit. It gives also easy and high cost saving by view point of installation. 6-way cooling and heating reversing system was introduced to make good design optimization as operating cooling and heating system on fan coil unit. It gives cost saving and easy control during reversing or direct cooling hand heating operation. This study shows visible comparison conventional to innovative approach for hydronic system.

Cinical observation was made of 30 cases of surgical patients who were operated with perforation of the ileum secondary to salmonellosis, which were experienced from July, 1967 to Oct., 1973 at the department of general surgery of Chungnam National University Hospital. The results are as follow 1. Recently the incidence of perforation of the ileum due to salmonellosis has a tendency to increase. 8 cases(26.7%) in 1973, 8 cases (26.7%) in 1972, 7 cases(23.3%) in 1971, 3 cases(10.0%) in 1970, 1 case in 1969, 2 cases in 1968, 1 case in 1967. 2. The occurence of salmoellnosis was most frequent in summer. 3. Salmonellosis was occured most frequently in those between the age from 20 to 29 years old and the male-female ratio was 2:1. 4. Perforation was developed most frequently at 11th. to 20th. day after onset and the duration from perforation to operation was most frequent in 2 to 3 days. 5. 6 cases(20%) were operated within 24 hours after perforation, then there was no expired case, that was contributed to the decresed mortality rate. 6. Subdiaphragmatic free air in simple X-ray was found in 75% of perforated cases. 7. The site of intestinal perforation was within 60cm. proximal to ileocecal region in 73.3% of the perforated cases. 8. In surgical management, simple suture of the lesion was performed in 73.3% of the cases and end-to end anastomosis after resection was done in 16.7%, exteriorization was done in 10.0%. 9. The incidence was higher in rural (77%) than in city(23%). 10. Complications after surgery were wound infection: 23%, wound disruption: 14%, intestinal fistula: 7%, liver abscess: 3%, mortality rate:30% 11. In the hematologic finding on admission, the leucopenic change(below 6000/mm3 in W. B. C.) was in 43.3%. 12. The result of Widal test was positive in 47% (above 160X). 13. The diagnoisis of ileal perforation was confirmed in all biopsied cases (12 cases) as salmonellosis. 14. The overall mortality rate was 30%.

To investigate the side effects of the adriamycin on bone marrow and peripheral blood morphologically, all ADR-treated rabbits were given a dose of 0.6mg/kg on alternate days, three times a week, achieving a total cumulative dose of 11mg/kg to 44mg/kg. In each group, the bone marrow tissue and peripheral blood are obtained 24 hours after termination of injection, and stained with Wright-Giemds & perexidase in bone marrow, H-E & reticulin in peripheral blood. The results are as follows: 1. The cellularity of the bone marrow was decreased as the dosage of ADR was increased. The most prominent group revealed the changes similar to the findings of aplastic anemia. That is, the marrow was nearly filled with plasma cells, lymphocytes, and histiocytes. But the fibrosis of the marrow was not seen. 2. One month after termination of treatment of the ADR, the cellularity of the marrow was increased to 30% and all the cells of the marrow were recovered. 3. After treatment of ADR, the platelet of the peripheral blood were decreased rapidly, but the myeloid and erythroid cells were decreased progressively. The degree of the change was more marked in larger dosage group. After stop of the treatment, all cells were recovered to nearly normal state rapidly.
